Proteomic Characterization of Host-Microbe Interactions in the <i>Euprymna scolopes</i> Light Organ Symbiosis with <i>Vibrio fischeri</i>
Schleicher, Tyler R
The squid, Euprymna scolopes, and the bacterium, Vibrio fischeri, form a highly specific relationship that is used to study how beneficial bacteria interact with animal hosts. Even though the light organ of E. scolopes is exposed to the outside marine environment, it can only be colonized by V. fischeri. For this reason E. scolopes must carefully control the light organ microenvironment. One mechanism that the squid utilizes to regulate this symbiosis is a daily expulsion of V. fischeri from the light organ. The squid expels the symbiont, in addition to some host tissue, as a thick exudate that was collected and analyzed by high-throughput mass spectrometry (MS)-based proteomics. As expected, many of the V. fischeri proteins identified exemplify the lifestyle of the symbiont in the light organ including quorum sensing and the management of oxidative stress. The function of one of the V. fischeri proteins identified, a bacterial immunoglobulin-like surface protein, was further characterized by creating a mutant deficient in this protein. Host proteins within the light organ also highlighted the oxidative microenvironment, but proteins associated with innate immunity were prominent as well. The innate immune response, including macrophage-like hemocytes, of E. scolopes is considered to provide an additional regulatory component to this host-microbe relationship. In the absence of adaptive immunity, the hemocytes still have the ability to differentiate V. fischeri from non-symbiotic bacteria. To get a better understanding of the molecular mechanisms involved in determining host-symbiont specificity, two quantitative proteomic techniques (iTRAQ and label-free spectral counting) were used to characterize the influence of light organ colonization on the squid hemocytes. These studies demonstrated that the presence of V. fischeri in the light organ can alter the composition of the hemocyte proteome by affecting proteins related to the cytoskeleton, adhesion, and innate immunity. Further characterization of symbiont recognition by the host involved the analysis of the transcript distribution and protein localization of two carbohydrate-binding galectins. These studies represent the first application of a variety of MS-based proteomic techniques to the squid-vibrio symbiosis. In addition, the data generated from these analyses have laid the foundation for the characterization of many new target proteins, which may have important functions in regulating and shaping the outcome of host-microbe relationships in general.

THALASSEMIA: AN ANTHROPOLOGICAL STUDY OF 86 PATIENTS AND THEIR FAMILIES IN CYPRUS
BOOK, PATRICIA ANN
This is a study of thalassemia on the island of Cyprus where 27 percent of the population carries one of the thalassemia genes. Thalassemia is an incurable genetic disease of childhood in which death occurs during the first year if untreated. With modern costly treatment, including monthly blood transfusions and related symptomatic therapy, affected persons commonly live into their teens.^ Thalassemia is an inherited defect in the synthesis of the adult hemoglobin molecule. Evolutionary theory suggests that its high incidence in human populations was the result of a balanced polymorphism where thalassemia heterozygotes had a reproductive advantage due to natural protection from the malaria parasite. With the eradication of the presumed selection factor (malaria) after World War II, the human adaptation to environmental stress no longer applies.^ The primary aim of the study is to describe and assess the quality of life of thalassemic children in Cyprus. From this ethnographic and statistical analysis it is possible to identify those factors of home life, social relations, and medical care which contribute to more positive coping behaviors (of the children and their parents) in the face of terminal illness.^ In this study, it was hypothesized that children from more cohesive families, with higher socioeconomic status, casual adherence to the Greek Orthodox religious tenets would exhibit more positive adjustment as would those with medical management approximating a more comprehensive treatment program, with little manifest deformity. Field work to test these hypotheses was carried out in Cyprus over a seven-month period in 1976-1977.^ Extensive formal interviews, psychological testing, direct observation, home visits, school visits and teacher ratings provided the data for testing the hypothesis.^ Considerable variation in patient adjustment was documented. One-third of the patients were identified as experiencing significant coping problems.^ Among the variables tested for association with patient adjustment, family cohesiveness is most important. In addition, components of other variables were related to several aspects of patient functioning.^ Results of the study indicate that patient psychosocial well being depends not only on optimal medical management. Maintaining family functioning is critical to good patient adjustment. Future program plans recommended include, in addition to continued optimal medical management, patient education services, family counselling services, and disease prevention. ^

THE EFFECTS OF SELECTED BLACK LITERATURE ON THE ATTITUDES OF WHITE ADOLESCENTS TOWARD BLACKS
MARTIN, JEAN-PROCOPE
The purpose of this study was to measure the effect of a four month experience with Black literature on attitudes of White suburban adolescents toward Blacks. The sample, consisting of 435 pupils (215 female, 220 male) was selected from ninth grade students attending six suburban schools in communities surrounding a northern city.^ An instrument, Multifactor Racial Attitude Inventory, introduced as a pretest and posttest to assess racial attitudes, and a Black Literature Package, compiled by the author, was introduced as the study treatment. External validity was controlled by The Solomon Four-Group design. The experimental groups took the pretest and became involved with the Black Literature Package during the four month period. These groups read the Black literature selections after taking the pretest and produced written personalized reactions to these readings during the treatment. Following the treatment, a posttest was administered. The control groups took the pretests and posttests specified by the research design but were not exposed to the treatment. Sex, reading comprehension and IQ were studied as potential sources of confounding influence on racial attitude.^ The study posed several questions concerning the impact of the Black Literature Package on racial attitudes of these students and dealt with the question of whether or not differences in attitude depend on individual differences in sex, reading comprehension and IQ. When racial attitude is thought of as a multifactor construct, Hypothesis One was rejected for two subscales, Gradualism and Ease in Interracial Contacts and Hypothesis Six was rejected for one subscale, Private Rights. If one views racial attitude as a single global dimension, all null hypotheses under investigation would be retained. The findings previously stated when racial attitude is looked upon as a psychological domain having many components, suggest that some of these components are susceptible to relatively short term change.^ The results of the study provided evidence for the necessity of strengthening the Multifactor Racial Attitude Inventory for measuring attitudinal change in adolescents as well as the desirability of supplementing such quantitative measures by more subjective kinds of response such as written personal reactions. An inspection of the students' written responses disclosed clear, positive attitudinal change in a number of cases. Although difficult to quantify, these writings reflected positive attitudes toward characters in the literary selections and were considered by this researcher to be an important experimental outcome.^ A previous study by Page (1974) investigated the extent to which racial attitudes of eleventh grade students change after reading Black literature. His findings suggested that Black literature read by students at that grade level for five weeks independent of or in conjunction with the teacher did not transform negative attitudes into positive attitudes.^ A later study sought to determine the influences of literature read since grade six on racial attitudes (Culp, 1976). The findings in this case revealed that the majority of students had been influenced to some extent in their attitudes, values, and behavior by reading literature. The effects of reading literary works by Black and White American writers on attitudes of students toward Black literature was assessed by Cooke (1971). Her findings indicated a significant improvement in Black literature after students had read works by both Black and White Americans.^ Based on the literature review, one would expect racial attitude, in general, to be resistant to short term effects. The present study, while supporting this view along those dimensions of racial attitude, suggest that, particularly in the case of Gradualism and Ease in Interracial Contacts, short term treatment may produce significant change. ^

THE EFFECT OF TWO TECHNIQUES WHICH ELICIT PREDICTIVE RESPONSES ON THE COMPREHENSION OF CONTENT AREA READING MATERIAL
MURRAY, EDWARD THOMAS
Nonvisual information affects the meaning that students derive from print. The present literature reflects theories that attempt to describe the relationship between the reader and the text. Two theories have strongly influenced this investigation into prereading strategies, the transactional theory of literature as described by Louise Rosenblatt (1978) and the model of comprehension as explained by Frank Smith (1978).^ Lesson structure investigations and various methodologies which attempt to guide students through their content area texts provide little empirical support for prereading activities. This investigation, therefore, examines the effect of two prereading strategies involving prediction on student comprehension scores in secondary content area reading tasks. The anticipation guide is a technique that asks probing questions on the subject to be read with the intention of adjusting student schema and activating relevant prior knowledge. The brainstorming guide serves the same purpose but is designed differently. Its implementation places the onerous on the teacher to motivate, involve, and guide students' predictions for the purpose of enhancing comprehension of the content area text.^ This research examines the interrelationships between the treatment groups and the dependent variables; the cloze test and a passage dependent multiple choice test. The research also examines the instructional effects of a prereading cloze passage on student comprehension. The study is guided by these questions: What relationship exists between the use of prediction strategies and student comprehension of content material? Can differences be measured by using a cloze passage comprehension test and a multiple choice passage dependent test?^ The test population includes 72 tenth and eleventh grade students from a multi-ethnic, diversified socioeconomic population at an urban high school in Connecticut.^ Analysis of variance design is used to test the hypotheses: (1) No significant differences exist at the p < .05 level among the means of reading comprehension scores of students on a passage dependent multiple choice test or a cloze test when grouped according to T(,1) (anticipation guide), T(,2) (brainstorming guide) and Control (no treatment). (2) No significant differences exist at the p < .05 level among the means of reading comprehension scores of students grouped according to C(,1) (receiving a cloze test) and C(,2) (not receiving a cloze test). (3) No significant interactions exist at the p < .05 level between T(,1) (anticipation guide), T(,2) (brainstorming guide) and Control (no treatment) and C(,1) (receiving a cloze test) and C(,2) (not receiving a cloze test) with respect to reading comprehension scores on the cloze test or the passage dependent multiple choice test.^ Within the limits of the study it appears that the prereading treatments do the following: (1) Brainstorming guides apparently help students to comprehend their textbooks, to become actively involved in the reading process, and to mobilize prior knowledge and activate relevant schema. (2) Anticipation guides may enhance comprehension when used with appropriate classes. (3) Prereading cloze may be used more effectively as a measure of readability than a prereading instructional device.^ The findings indicate that students may comprehend more when they are adequately prepared for the reading task. Even though the text used in the study was written at a readability level that was too difficult for the classes, the brainstorming strategy had a positive effect on passage dependent comprehension scores. Therefore, it is concluded that instructional practices should contain elements that allow for the mobilization of prior knowledge schema adjustment techniques. These techniques should be designed so that students are obligated to make predictions about the content of the material that they are to find in their text books. ^

A COMPARATIVE ANALYSIS OF THE PERCEIVED HUMAN, TECHNICAL AND CONCEPTUAL COMPETENCIES OF SELECTED ELEMENTARY SCHOOL PRINCIPALS, COMMUNITY SCHOOL DIRECTORS, HUMAN SERVICE AGENCY DIRECTORS AND HUMAN SERVICE AGENCY PROJECT ADMINISTRATORS
WARREN, RICHARD
Background. Katz (1954, 1972) advises all leaders perform tasks requiring human, technical and conceptual abilities. Many leadership training programs have been premised upon this belief. Training administrators in community education is a fairly recent occurrence. Most of this training is occurring in the field of educational administration. However, DeLargy (1975) suggests leaders in community education perform different duties than other educators. Literature implies community educators may perform duties similar to those required by human service administrators. Past research is not available to support nor reject this inference. Therefore, this study was conducted to determine if the perceived human, technical and conceptual skills of community education administrators were more similar to the group they are trained with or to a group that performs similar tasks. The variables: sex of administrator, academic training and past administrative experiences were considered in analyzing the data.^ Sample. Administrators in nine Massachusetts cities with 50,000 to 100,000 inhabitants and one certified community school were identified. From the pool of available administrators, 30 Elementary School Principals; 30 Community School Directors; 30 Human Service Agency Directors and 30 Human Service Agency Project Administrators were selected. One research assistant per city was employed. 100% of the data was collected and deemed usable in the analysis of data.^ Statistical Procedures. A questionnaire was utilized for data collection. Content validity and reliability of the instrument were determined by utilizing the KR 20 process. One-way analysis of variance was utilized to compare the perceived levels of competencies of each group. Each null hypothesis was rejected at the .01 level of significance. Two-way analysis of variance was utilized to determine differences in perceptions of males and females. Each null hypothesis failed to be rejected at the .05 level of significance. Tukey's post hoc comparison test was utilized when significant differences occurred. Frequency distributions were utilized to describe academic training and administrative experiences.^ Findings. Community School Directors and Elementary School Principals perceived their human skills more similarly than both groups of Human Service Agency Administrators. Community School Directors, Elementary School Principals and Human Service Agency Directors expressed similar levels of perceived technical and conceptual competencies. However, Community School Directors cited such technical skills as: oral and written communications; finance and marketing more frequently than the other groups. Conceptual skill scores for all groups were distinctively lower than the other competencies. However, community education literature strongly implies leadership based on sophisticated abilities to conceptualize. There was no significant difference in perceived competencies between sexes. However, the ratio of female community education administrators appears to be distinctively greater than females in other educational administrative positions. Community Educators represented about half the past administrative experiences and significantly less academic training than other groups included in this study. Similar levels of perceived skills indicate: Community Educators perform administrative tasks similar to Principals and Agency Directors; or it may infer that it is the profession and not the academic or administrative experiences that effect the perceptions. Human Service representatives and Elementary School Principals were trained in a field allied to their profession. Conversely, Community School Directors exhibited diversified academic backgrounds. There may be a link between varied academic background, minimal administrative experience and School Superintendents understanding of community education's leadership requirements. ^

A PHENOMENOLOGICAL STUDY OF TEACHING ROLE PERCEPTIONS OF COLLEGE AND UNIVERSITY PROFESSORS WHO ARE RECIPIENTS OF AN OUTSTANDING TEACHING AWARD
SANDERS, PATRICIA
This phenomenological study reports on teaching role perceptions derived from in-depth interviews with 10 college and university professors in Connecticut four-year institutions of higher education who were identified for teaching excellence through an Outstanding Teaching Award. Recipients identified by faculty and/or administrator groups were contrasted with recipients identified by student groups on three research questions related to self-perception of teaching role, perception of students and perception of the teaching/learning dynamics in the college or university classroom.^ Analysis of the interview data revealed three distinct teaching role orientations: evocative, didactic, and affiliative. The teaching role orientations are based upon a synthesis of the professors' reflections related to the three research questions under investigation. The three orientations are described in detail.^ Analysis of the information supplied in the Professor Profile Questionnaire indicated that award recipients in both groups were approximately the same age at the time the Award was presented. Some minor differences, however, are noted between the two recipient groups. Professors who are recipients of faculty/administrator selected teaching awards have lighter semester teaching loads, teach more graduate students, hold a higher academic rank, are more tenured and are more productive publishers than professors who are recipients of student selected awards. These data support the research literature relative to criteria used in determining teaching effectiveness, that is, students use different criteria from faculty and administrators in evaluating teaching excellence. Furthermore, four of the five professors in the faculty/administrator selected recipient group fit the description of the academic "good man theory." The "good man theory" is descriptive of the academic professional who does everything--teach, research and perform service--and does it well.^ A further analysis of the data revealed that the teaching professors in this study possess the following common characteristics: (1) they are committed to scholarship; (2) they accept teaching as an important responsibility and are committed to fulfilling that responsibility with distinction; (3) they have a "conceptualized" understanding of the multiple parts of their academic work; (4) they have the ability to "personalize" classroom instruction; and, (5) they have the capacity to form and enter into good interpersonal relationships with students and colleagues.^ Other findings include: the professors demonstrate an "implicit but manifest" theoretical underpinning for their teaching; the professors have reached "maturity" in their teaching; the professors perceive scholarship and research as providing more resources from which to draw upon in their teaching; the professors have a clear understanding of the nature and needs of their students; early socialization to an academic career is teaching oriented; two professors made mid-life career changes into college and university teaching; the professors emulate the behaviors of their teachers whom they considered to be outstanding. Emulation, however, is a "subconscious" process.^ Five "essences" of teaching excellence were identified for the 10 professors. They are: intrinsic motivation, self-evaluation, natural teaching talent combined with "working" at teaching, congruence between "professor-as-person" and "professor-as-teacher," and "togetherness."^ Implications of the study for higher education are discussed and suggestions for future research are presented. Appended to the text are the schedule of interview questions, data on Teaching Award Programs in Connecticut four-year institutions of higher education and the professors' perceptions related to the significance of teaching awards. ^

CHOU EN-LAI, CREATIVE REVOLUTIONARY
WEIDENBAUM, RHODA SUSSMAN
This biographic study of Chou En-lai covers the period from his birth to the age of twenty-nine and traces the early emergence of key leadership characteristics. Psychoanalytic theory is used as an interpretive framework and Erik Erikson's theories regarding the stages of personality development and growth are applied. Basic causes, from the Freudian point of view, of Chou's impulses towards revolutionary activity are identified.^ The study opens with an analysis of Chou En-lai's family background, education and experience as a teen-ager. His years in Europe, especially France, where he committed himself to communism, are analyzed in detail. Consideration is also given to the background of his wife, Teng Ying-ch'ao, and to their marriage.^ Chou En-lai's early political career after he returned to China is emphasized. This includes the period of the first United Front between the Kuomintang and the Chinese Communist Party, when Chou was Political Director of the Whampoa Military Academy, Commissioner of the East River District and Political Adviser to the First Division of the National Revolutionary Army, which was commanded by Chiang Kai-shek. It also includes his activities as an underground operative in Shanghai during the period of the breakdown of the alliance. The study concludes with a reconstruction of the Nanch'ang Rebellion of 1927. Chou En-lai played a major role in that insurrection, which, although a failure at the time, is now regarded as having led to the founding of the Chinese Red Army. ^

RAPID PRECISION INTERFEROMETRY FOR THE ANALYTICAL ULTRACENTRIFUGE
LAUE, THOMAS MAXON
Four instruments have been designed, constructed and tested that speed up the taking of data from the analytical ultracentrifuge Rayleigh interference optical system. The Raleigh interference optical system produces a cell image in which the concentration at each radial position is represented by the vertical displacement of a set of equally spaced horizontal fringes. The first instrument determines the fringe displacement from interferograms. The seconds instrument mounts directly on the ultracentrifuge and measures the fringe displacement at a single radial position every twelve seconds. The third system determines mounts directly on the ultracentrifuge and measures the fringe displacement at 342 radial positions every 20 seconds. The fourth instrument synchronizes the operation of the data taking devices with the pulsed laser light source used to produce the Rayleigh images. Data is presented demonstrating the performance of each of the four systems. ^

AN ANALYSIS OF THE PRODUCTIVITY OF GIFTED STUDENTS PARTICIPATING IN PROGRAMS USING THE REVOLVING DOOR IDENTIFICATION MODEL
REIS, SALLY MORGAN
This study was undertaken to analyze the use of a new identification system, the Revolving Door Identification Model (RDIM), which was substituted for the more traditional identification systems in twelve school districts throughout Connecticut. The purpose of this study was to develop a product rating scale, the Student Product Assessment Form, which was used by raters to assess the differences in the quality of products completed by male and female students in the gifted programs in these districts. Students were divided into two groups: female and male students who would have been identified by traditional guidelines (usually the top 1-5% as selected by high scores on an achievement or IQ test), and female and male students who would not have been traditionally identified but who entered the program under an expanded set of criteria. Additionally, the study analyzed whether sex or grade level affected the process of students "revolving in" to the resource room of the gifted program to complete advanced level products. This study also analyzed the effects of implementing the RDIM, which identifies 15-25% of the student population as being eligible to participate in the gifted program.^ The procedures used to determine the proportion of students who revolved in to the resource room to complete advanced level products showed that a significantly higher proportion of females revolved in than males. Additionally, it was found that a significantly higher proportion of 4-6 grade students revolved in than 1-3 grade students.^ Analysis of variance procedures showed no significant difference in the quality of products completed by students in the two groups and no significant difference in the overall quality of products completed by males and females. Although some significant interactions between sex and group with respect to the quality of products was found, follow-up t-tests revealed no significant differences between males and females in either group on the Total of all of the Key Concepts on the Student Product Assessment Form. Finally, a qualitative analysis on the effects of implementing the RDIM showed that the model was highly successful across the field test districts. ^

COORDINATION AMONG ARTICULATORS IN SPEECH
TULLER, BETTY HELEN
The present experiments explore temporal relationships among articulatory events as a function of changes in speaking rate and syllable stress. The first experiment was designed to examine the adequacy of two basic types of explanation that have been proposed for these changes. One view is that the segmental "commands" for syllables spoken quickly and for unstressed syllables show more extensive temporal overlap than the same syllables spoken more slowly or with greater syllabic stress. An alternative view is that the temporal relationships among articulations remain constant over changes in speaking rate and stress but the individual gestures themselves vary. The results support the latter hypothesis. Electromyographic (EMG) activity in the articulatory muscles examined (genioglossus and orbicularis oris) showed that aspects of the motor activity underlying lip movements for bilabial stops and tongue fronting for the vowels /i/ and /e/ maintained a tight absolute temporal constancy. The second experiment explored whether this constancy of absolute temporal patterns over changes in speaking rate and syllable stress is unique to the genioglossus and orbicularis oris muscles, is a general characteristic of speech motor control, or is a special case of a more general constraint on relative temporal patterns. EMG recordings from lip, tongue and jaw muscles were obtained so that temporal aspects of muscle activity could be examined over more phonetic segments than possible in Experiment 1. The results suggest that an adequate description of speech motor coordination may be in terms of relative timing constraints. The similarity between this view of coordination among articulators in speech and the style of coordination in other motor systems is also discussed. ^

THE STATE AND SOCIOECONOMIC TRANSFORMATION IN THE SUDAN: THE CASE OF SOCIAL CONFLICT IN SOUTHWEST KURDUFAN
SAEED, ABDALBASIT
This study addresses social conflict in southwest Kurdufan. It espouses historical materialist concepts. Accepting the conventional view of conflicts as ethnically-articulated, I argue that conflicts are founded upon class relations of production. More importantly, is how and why conflicts came to be what they are. Data presented stem from a view of social transformation as necessarily involving transforming relations of production, and conflicts which such changes generate.^ In southwest Kurdufan, tribalism, ethnicity, sufism, and mystic association (the prevailing ideologies of the power structure) are not regarded as false; but are real and effective forms of socio-cultural identification and avenues in which conflict is articulated. But forms of conflict may also be read as manifestations of contradictory interests: having their genesis in historical processes determined by, and explicable in terms of production relations in situations, like the Sudanese, of rapid socioeconomic changes throughout this century. Such destabilizing changes inevitably generate conflict because of the uneven and inequal distribution of wealth.^ More recently, conflicts increased due primarily to drastic shifts from accumulation based on pre-capitalist standards of status and prestige, to accumulation of private property in money, land and animals effected by imposition of capitalist production by colonialism. After independence a national client bourgeoisie controlled State power and perpetuated dependence on imperialism and indigenous exploitation. These classes are represented locally by mercantilists, provincial bureaucrats, and tribal dynastic leaders (whose interests are no longer anchored at the local level). By analysing relations by which dominant fractions exploit rural direct producers, I argue that conflict is no longer triggered primarily by intervention of animals in cultivated plots, but between pastoralists without pasture, by class fractions in land ownership disputes, and by opposition to imposition of exploitative relations by the State and its plans for capitalist development which permit intervention of international finance institutions and multinational oil companies, and which suppress rural populations under the pretext of 'maintaining law and order'. ^

A STUDY OF PREDICTORS OF ALUMNI PHILANTHROPY IN PRIVATE UNIVERSITIES
BEELER, KARL JOSEPH
College alumni are in a powerful position to influence all sources of voluntary support to higher education. An increase in alumni support can result in gifts and grants from foundations, corporations, and private benefactors which exceed the amount of alumni contributions manyfold. Surprisingly little is known, however, about the characteristics and attitudes of alumni donors.^ The purpose of this study was to test the ability of fourteen demographic and attitudinal variables to discriminate between alumni donors and non-donors, as well as limited donors and substantial donors, to the annual campaign of a private research university in the Northeast.^ A questionnaire survey was mailed to 1000 randomly-selected alumni who had graduated from the institution between 1960 and 1969. Applications of one-way multivariate analysis of variance for 744 respondents, blocking on year of graduation by academic performance and number of extracurricular activities, indicated that the sample was relatively homogeneous and could be analyzed as a group.^ To test the initial hypothesis of no difference between the donor and non-donor groups on each of the independent variables, analysis of variance procedures were applied. To assess the combined ability of these variables to predict group membership as donor or non-donor, a single function, two-group discriminant analysis procedure was applied; this procedure was then repeated for a disaggregated sample to assess the prediction of group membership as limited donor or substantial donor.^ Donors and non-donors differed significantly on eight variables: year of graduation, undergraduate school, receipt of institutional scholarship or grant, enrollment at another college subsequent to graduation, distance of permanent residence from campus, current occupation, satisfaction with undergraduate preparation for first job, and emotional attachment to alma mater. For the donor versus non-donor discriminant analysis, the discriminant function correctly predicted group membership for 64.11 percent of the cases, 24.8 percent better than chance. Emotional attachment, current occupation, undergraduate school, and receipt of institutional scholarship or grant were the best predictors of group status. For the limited donor versus substantial donor discriminant analysis, the discriminant function predicted group membership for 75.00 percent of the cases, 55.2 percent better than chance. Emotional attachment and current occupation were the best predictors of limited or substantial donor status.^ Suggestions for further study included replication of the study in varying types of institutions, such as public research universities, regional state universities, and liberal arts colleges. Also suggested were field validation of the optimal classification equations and applications of research designs with additional variables. ^

MORPHOLOGY, ULTRASTRUCTURE AND EVOLUTIONARY SIGNIFICANCE OF MONOSULCATE POLLEN
ZAVADA, MICHAEL STEPHAN
Data on pollen wall development of a variety of major taxa was examined to help establish homologies among different types of pollen walls and to contribute to understanding evolutionary trends in pollen wall ontogeny. Comparative morphological and ultrastructural studies of monosulcate pollen were also conducted to determine evolutionary trends in pollen wall structure of major extant angiosperm taxa. A number of Mesozoic dispersed saccate and non-saccate pollen were also examined ultrastructurally. The value of the dispersed Mesozoic pollen record in clarifying angiosperm origin(s) and radiation is discussed against the background of these data. ^

ASPECTS OF MISCIBILITY IN POLYMER SYSTEMS: HYDROGEN BONDING IN POLYMER BLENDS (PVC, POLYCAPROLACTONE)
CANGELOSI, FRANK
The importance of hydrogen bonding interactions in promoting miscibility in polymer-polymer blends has been demonstrated. Hydrogen bonding is considered to be responsible for the large number of compatible blends involving poly(vinyl chloride), poly(caprolactone), and several water-soluble polymers. This research has been undertaken to understand the structural requirements for hydrogen bonding in polymer blends, with the goal of providing molecular explanations for the phase behavior of selected polymer-polymer systems, and a basis for predicting phase behavior of new systems. The method of analysis has been infrared spectroscopy; the locations of the absorption frequencies of potentially hydrogen bonded groups (hydroxyl and carbonyl absorptions) were monitored on carefully selected "probe" molecules. The intensities of the bonded and nonbonded peaks were compared to measure the percentage of bonded groups, while the amount of shift (from nonbonded absorptions) was used to determine hydrogen bond strength.^ Mixtures of low molecular weight monofunctional probes incorporated into a variety of polymer matices were studied in order to determine the effect of molecular size and geometry on the strength of a hydrogen bonding interaction. Cyclic base probes were found to interact more strongly than straight chain molecules; probe geometry was not significant in mixtures of monofunctional acid probes. Results of these studies were also used to rank polymer matices in terms of their potential to interact with another polymer.^ The interaction of oligomeric probes with several polymers was also investigated. These materials were ideally large enough to interact with matrix as would a polymer, but small enough to preclude intramolecular hydrogen bonding and phase separation. However, probe-probe interactions were found to dominate in these blends; the strength of these interactions was usually a function of the polymer dielectric constant. Thus, the number and strength of self-associations which had to be broken to achieve miscibility were important. Also, the effect of weaker non-specific interactions, such as dipole-dipole, was significant.^ Changes in subtle variables, including polymer tacticity, functional group concentration, and matrix molecular weight, were also studied. ^

PREHISTORY OF THE LOWER CONNECTICUT RIVER VALLEY
MCBRIDE, KEVIN ALLEN
The research upon which this dissertation is based was collected over a four year period. The research included studies in ethnohistory, geography, paleobotany and cultural ecology, conducted within the context of an archaeological survey of the lower Connecticut River valley. The primary objectives of the research were to construct a regional culture history of the lower valley, and to document changes in regional settlement patterns through time.^ Over 350 prehistoric sites were located through a combination of field surveys and informant interviews. Located sites ranged in age from 8,000 B.C. to A.D. 1700.^ Based upon excavations at over 60 of these sites, nine distinct phases were identified in the lower Connecticut River Valley, from the Archaic (ca. 2500 B.C.) through the Contact Periods (ca. A.D. 1600). Two major changes in aboriginal settlement patterns were detected. The first, beginning around 1000 B.C., indicates a trend toward a more logistically oriented settlement system, with large seasonal occupations located along the Connecticut River and smaller temporary and task-specific locations in the uplands. This trend continued throughout the Woodland Period, where it culminated in sedentary villages around A.D. 1000.^ The second major change in settlement patterns began around A.D. 1500, when the settlement system was characterized by the presence of small seasonal upland camps, demonstrated to be associated with small extended or nuclear families. This orientation towards smaller economic units indicates some important changes in aboriginal socio-economic systems during this period.^ Several potential explanations for these settlement shifts are examined in this thesis. The initial settlement shift to riverine areas may be the result of increased reliance on wetland resources, or developing trade networks with the upper Hudson valley. The second settlement change to smaller subsistence units could be the result of either intensification of horticulture, or early contact with Europeans.^ Data on site distributions and site types are presented and discussed for each defined phase. The data for each phase are then assessed with respect to current models of settlement and subsistence in southern New England. ^

FINANCIAL VARIABLES PREDICTIVE OF COLLEGE DEMISE
KACMARCZYK, RONALD HENRY
Recently, the National Association of College and University Business Officers (NACUBO) developed an instrument that collegiate institutions could use to gauge their fiscal status during these financially beleaguered times in academe. However, the NACUBO instrument has not been broadly tested for its utility.^ It was therefore the main purpose of this study to test the instrument preliminarily by answering to what extent and in what manner 27 selected NACUBO indicators could differentiate open from closed, small, less selective liberal arts (L.A. II) colleges. Financial data on 284 small, open L.A. II colleges and 19 small L.A. II colleges that had closed or merged with other institutions between 1976-77 and 1981-82 were first garnered from the National Institute of Independent colleges and Universities. Then, discriminant function analysis was utilized, yielding an equation with ten significant predictors. Of these, three accounted for 67% of explained variance: (1) Financial Full-Time Equivalent Student Enrollment was derived by subtracting unrestricted-fund scholarships and fellowships from tuition and fees and then dividing that figure by annual tuition rate. The indicator may suggest that, to meet expenses, tuition dollars must be used sparingly in subsidizing students. (2) Private Gifts, Grants, and Contracts Proportion was derived through division of private funding by educational and general expenses along with mandatory transfers. The indicator may note varied income as an important contributor to solvency. (3) Student Services Expenditures per Student was derived through division of student services expenditures by the Higher Education Price Index and then through division by total students. The indicator may suggest that student services (particularly counseling) are important in student retention.^ The equation explained 44.12% of all variance (p < .0001). The cut-off D value was -32.99. The centroid equalled -30.68 for closed colleges and -40.67 for open colleges. The equation correctly classified 292 of 303 colleges (96.4%). This was 62.7% above chance (p < .001).^ The study therefore suggested that the NACUBO instrument may be a powerful tool, at least for small L.A. II colleges. The study also provided a model through which L.A. II colleges might partially gauge their well-being. ^

SOCIALIZATION AS A FUNCTION OF CLASSROOM HUMOR
KUHLIG, RUTH ELAINE
Recently there has been an increase in research focusing on children's humor. The research, however, has been concerned with an individual's or group's response to a particular stimulus. There has been a lucunae of research which examines in situ the invention, presentation, and appreciation of children's classroom humor.^ This ethnography determines the function of classroom humor by examining closely the activities, expressed attitudes, and roles which exist in the classroom. The research examines the information obtained from participant observation, formal and informal interviews, and written documentation from schools, teachers, and students. Analysis is made by identifying categories of behaviors which are co-existent with humorous situations.^ The goals of this research are to attempt to understand humor's function in the classroom, to develop a model which pictorally represents classroom activities and humor's role among these activities, and to generate a grounded theory about humor's function for school groups.^ This research concludes that humor functioned as a socializer in the classrooms studied. The socializing effect occurred in three ways. First, the teachers employed the "joking relationship" to inform students of group expectations; secondly, teachers used and encouraged the use of certain humor techniques in the classroom; and thirdly, the definition of acceptable humor was given by teachers in several ways.^ The model presents a picture of classroom behaviors as if the teacher were a tightrope walker carrying children from one platform (grade) to another. Humor is designated as a balancing pole to be used by students to aid both teachers and pupils to reach their goal.^ The grounded theory emphasizes the importance of the teacher's definition of what is humorous. Rather than simply a tool for persons to use in coping with their individual lives, humor acts as an acceptable way to inform children of social expectations. ^

THE PREPARATION OF SMALL METAL PARTICLES ON ZEOLITES AND OTHER SUPPORTS (MICROWAVES, MOESSBAUER, FISCHER-TROPSCH, FERROMAGNETIC RESONANCE)
MCMAHON, KERRY CHARLES
Small metal particles in the cages of zeolites can be selective catalysts for the production of hydrocarbons from carbon monoxide and hydrogen. Our research involves several different methods for the preparation of small particles of metal in zeolites. Iron and cobalt were the metals investigated.^ Success has been achieved through the use of a microwave induced argon plasma which decomposes metal carbonyls and organometallics to form small ferromagnetic metal particles. Characterization of these samples as to their chemical, physical and catalytic properties for Fischer-Tropsch synthesis has been done. Details of preparations and reactions are presented. ^

MARKETING IN THE CORPORATE BOARDROOM: A STUDY OF CORPORATE FUND RAISING FOR HIGHER EDUCATION
STEINBERG, MARGERY SUE
The purpose of this study was to collect and organize data on college and university fund-raising efforts during the past year (1982-83). It examined development directors' familiarity with and utilization of modern marketing techniques, and sought to document the relationship between selected variables and fund-raising success.^ This was a survey research project with an ex post facto design. The population for this study was comprised of development directors or officers from 525 institutions of higher education randomly selected from the 1981-82 National Center for Education Statistics Directory: Higher Education. The Corporate Fund-Raising Practices Survey and the Marketing Application Survey, both developed by the investigators were used to collect the data for this study.^ The existence of corporate fund-raising programs among all institutional types studied was extensive. On the average, development directors were somewhat familiar with modern marketing concepts, but their level of utilization was relatively low.^ Among the respondents, most perceived their fund-raising achievement to be satisfactory (36%) and unsuccessful (31%). Disaggregation of the data disclosed significant differences (.05 level) between institutional types and sizes, highest degree offered and student body mix in patterns of purposes addressed, organizational and institutional factors, patterns of fund-raising operations, methods of corporate cultivation, solicitation and follow-up in corporate fund-raising programs during the past year (1982-83).^ In a multiple regression exercise to test the efficacy of familiarity with and utilization of modern marketing concepts as predictors of fund-raising success, four significant (.05 level) predictors emerged: utilization of consideration of corporation's goals and interests, familiarity with an objective-based fund-raising budget, utilization of an objective-based fund-raising budget and utilization of market segmentation of target corporations. These four variables accounted for a modest amount of variance (12%).^ Further study in the areas of implementing marketing training for development directors, developing communications networks among development directors and understanding the vagarities and nuances of corporate fund raising for higher education was recommended. ^

NONLINEAR INVERSE METHODS APPLIED TO INTERPRETING GRAVITY ANOMALIES PRODUCED BY MULTI-INTERFACED GEOLOGIC BODIES
PAN, JENG-JONG
Nonlinear inverse methods can be used to determine shapes of source bodies directly from observed gravity anomalies when density distributions are known. Two nonlinear inverse methods are applied in this study, the nonlinear optimization and the least-squares methods, which are here grouped under optimization methods. For an initially assumed model of a geological structure, optimization methods obtain values for source parameters by iterative adjustments that minimize a nonlinear objective function. This function is the sum of the squares of residuals of observed anomaly minus calculated value at each station. Whether optimization methods can be used to delineate a particular structure depends primarily on whether an analytical formula can be developed to represent the gravity anomaly.^ The performance of ten different nonlinear, unconstrained and constrained, optimization methods and one least-squares method (see Table 1) are tested and compared in their abilities to resolve the shape of a given two-dimensional sedimentary basin model. These eleven methods provide quite adequate resolution in finding a solution to the specified problem, particularly Powell's method, the variable metric method, and Marquardt's method.^ Five hypothetical and one field structure (the Aleutian trench) are analyzed by Powell's method to illustrate the versatility of that method for simulating two-dimensional multi-interfaced earth structures. Other optimization methods can be developed to obtain similar analyses. The behavior of an objective function may be studied visually by means of two-dimensional cross-sections in an n-dimensional space. Contoured values of an objective function can indicate locations of solutions for acceptable structures. Contour patterns can also provide ranges of possible solutions. Multi-modality is the main characteristic of the objective function associated with a complex structure and is the consequence of nonuniqueness in inverse problems.^ Optimization methods applied in analyzing gravity anomalies produced by multi-interfaced structures can (1) provide high resolution for simple structures or, at least, find gross models for very complex structures in short computer time, (2) simulate various geological models where the corresponding objective function can be defined, and (3) indicate available constraints placed on some parameters. Other types of geophysical inverse problems can be similarly analyzed by optimization methods. ^

TECHNOLOGICAL CHANGE AND ENGLISH TEACHING: A DELPHI STUDY OF AMERICAN, BRITISH, AND CANADIAN ENGLISH EDUCATORS' VIEWS OF THE FUTURE OF SECONDARY ENGLISH TEACHING (WORD-PROCESSING, MEDIA, LITERACY)
BARBER, BETSY SUE
As rapidly expanding technology alters the ways in which people communicate, English educators face the increasingly insistent question of how to keep the teaching of secondary English responsive to these changes. While commentary from social critics, scientists, and futurists abounds, there has been no consensus among expert English educators. The availability of such a consensus would be of value to those concerned with the appropriateness of today's curriculum for tomorrow's world. Employing a modified Delphi technique, this study attempted to develop that consensus.^ A panel of 77 distinguished English educators from the United States, Britain, and Canada addressed specific ways English teaching might change by the year 2000 as a result of technology's impact on society or schools. They generated lists of potential changes from which 42 of the most commonly cited were selected for scrutiny. Through two additional rounds of questionnaires, they estimated the probability of occurrence for each change by 1990, 1995, and 2000, rated its desirability, and produced extensive commentary. Consensus was measured using medians and interquartile ranges.^ Among those developments on which the experts achieved consensus are the following.^ They identify four technological developments as having greatest impact on English teaching: widespread use of microcomputers, highly sophisticated forthcoming software, capabilities of telematic (telecommunications plus computers) interface, and cultural subordination of print to screen media.^ Although they foresee little change before the year 2000, panelists concur that by the end of the century English teaching will be based on a new definition of literacy--expanded to include all message systems. They believe basic reading, grammar, and mechanics skills will be taught by computer; that word processing will promote emphasis on text revision; that competence in networking and information handling will be viewed as basics; that media analysis will be emphasized; that literature will be taught via video as well as print, and that attention to more complex kinds of teaching and learning will result from more sophisticated electronic resources. ^

EFFECTS OF ENVIRONMENTAL AND SOCIAL CONDITIONS ON THE AGONISTIC BEHAVIOR OF THE MONGOLIAN GERBIL (MERIONES UNGUICULATUS) (TERRITORIALITY, DOMINANCE, AGGRESSION)
ALBANESE, NICOLA
The Mongolian gerbil is a colonial, burrowing rodent inhabiting deserts and semideserts. The burrow and burrow-related activities play a central role in the gerbil's environmental adaptation and may be a focus for social interaction and territorial behavior. If the gerbil's territoriality is influenced by the characteristics of its residence then, even in captivity, experimental environments closer to its natural habitat should foster stronger aggressive responses toward intruders than more dissimilar ones. Furthermore, potentially reproductive female-male pairs should be more affected by the presence of burrows than unisexual male pairs.^ A partition divided a 183 x 61 x 61 cm (6 x 2 x 2 ft) enclosure into two equal compartments. In three different environmental conditions, part of the floor was either left in place or removed to give access to tanks filled with dirt or hay. In two social conditions one female-male pair or two males were introduced in each of the two compartments. In the "Dirt" and "Hay" condition the animals burrowed and built underground nests and food chambers. In "Flat" they built shallow surface nests. On the seventh day of residence the partition between compartments was removed.^ The measures of severe fighting and death indicated a strong environment by social group interaction. The female-male groups showed maximal aggressiveness toward intruders in Dirt and less in Hay and Flat, whereas the male-male groups were not significantly affected by environmental change. The measures of mild fighting, threat, and chasing present a less clear picture and are discussed in terms of possible influences of the experimental arrangement. The differences in behavior between the female-male and male-male groups are discussed in terms of differential reactivity to environmental conditions and differences in the nature of the aggression displayed. It is argued that the agonism of the male-male groups may have been regulated by dominance relationships, whereas the aggressiveness of the female-male groups was of a predominantly territorial nature. The susceptibility of these two forms of social utilization of space to environmental and social conditions is discussed. ^

MATTEO RICCI, S.J. IN CHINA, 1583-1610: A CASE STUDY OF A PRECURSOR IN EDUCATIONAL ANTHROPOLOGY (JESUITS, CROSS-CULTURAL METHODOLOGY)
FORD, ROSALIE JUDITH
Educational Anthropology or EA is considered a 'new' field by educators and anthropologists alike. The literature indicates the earliest linkage of education with anthropology in the United States was around the turn of the century, while the term itself, educational anthropology, was coined in 1954 by Rosenstiel. In an attempt to establish some historical roots for this young discipline, the author investigated, as a possible precursor of EA, Matteo Ricci, a sixteenth-century Italian Jesuit who spent twenty-seven years in China. Ricci was selected as the subject of this study since he was representative of the era in which the parent discipline of EA, namely anthropology, generally took shape.^ Ricci gained entry into China when there was a policy of isolationism. His prolonged residence and acceptance by the Chinese were due, in large part, to his knowledge of Western science and his familiarity with the language and customs of the country. His interest in education and his association with the scholarly-gentry gained his acceptance as a mandarin and permitted him to view the culture in terms of its educational system. Given the fact that Ricci came to understand the Chinese best through a holistic approach, the purpose of this study was to determine to what extent Matteo Ricci embodies the techniques of contemporary educational anthropology and thereby provides an historical background for the discipline.^ Ricci's EA techniques in China were examined providing the standpoint for a comparative analysis of the discipline's methodological principles today. The analysis of the data indicated that there were seven Riccian methods with contemporary EA counterparts, three Riccian methods with no contemporary EA counterparts, and one contemporary EA method without a Riccian couanterpart.^ Matteo Ricci, therefore, could be considered a precursor of EA in that he was, by reason of this indoctrination in ADAPTATION, fully prepared, on entering China, to accept the Chinese "where they were"; in that he partially, but only partially, implemented the basic EA METHODOLOGY; and finally, in that, to a great extent, he implemented the DEFINITION of EA. ^

THE OPIUM OF THE CHILDREN: DOMESTIC OPIUM AND INFANT DRUGGING IN EARLY VICTORIAN ENGLAND (DRUG REGULATION, CHILDCARE, MORTALITY, WOMEN)
CHEPAITIS, ELIA VALLONE
Widespread narcoticism seems anomalous in Victorian England, a culture esteemed for its moral rectitude and strong family values. Yet, both early and mid-Victorian adults consumed staggering amounts of opium, and child drugging was commonplace in this environment. In some areas and among some income groups, opium feeding was nearly ubiquitous.^ The practice of feeding opiates to children was not clandestine, and was considered inhumane by contemporaries. Engels and Marx both mentioned child doping, and parliamentarians and medical men publicized the recklessness with which opiates were dispensed to infants. A large amount of evidence was gathered in the Parliamentary Papers and in professional journals, but child drugging and its ramifications have not been studied adequately.^ This dissertation is a two-fold study: of child doping and of inaction against drugging. The reasons why children were fed dangerous amounts of opium and the effects of excessive drugging are examined first. Opium-related infant mortality, deficiency diseases, and retardation are investigated using case studies and parliamentary testimony. Although it is impossible to determine with precision how many children were harmed by opium, the evidence of significant damage is convincing and consistent.^ The last chapters examine Victorian attitudes toward inebriates, and the dramatic increase in opium use by all age groups from 1821 to 1851. The conclusion surveys opium's decline and the movement to regulate drugs. Although the sangfroid of the early Victorians toward the maiming and killing of children is startling, especially in contrast with twentieth century antagonism toward drug abuse, critics of doping frequently noted their limitations--in medical theory, in law enforcement, and in altering custom and the social order. Reformers relied on public education to turn the public against opium feeding. Periodic investigations, as well as changes in living and working conditions did reduce drugging. By the 1890's opium's popularity had waned, and a social consensus on the desirability of controlling narcotics had emerged. ^

A SENSITIVITY STUDY OF THE GROUND HYDROLOGIC MODEL USING DATA GENERATED BY AN ATMOSPHERIC GENERAL CIRCULATION MODEL
SUN, SHU FEN
In this study, the Ground Hydrologic Model (GHM) developed by Lin, Alfano and Bock (1978) for use in an atmospheric general circulation model (GCM) has been refined. A series of sensitivity studies of the new version of the GHM were conducted for the purpose of understanding the role played by various physical parameters in the GHM.^ This version of the GHM has made the following refinements: (1) The GHM is coupled directly with the planetary boundary layer (PBL), using Deardorff's (1972) parameterization. (2) A bulk vegetation layer is added with a more realistic large-scale parameterization. (3) The infiltration rate is modified using Green-Ampt's (1911) formula.^ The GHM has been tested using input data derived from a GCM simulation run for eight North America regions for 45 days. The results are compared with those of the resident GHM in the GCM. The daily average of grid surface temperatures from both models agree reasonably well in phase and magnitude. However, large difference exists in one or two regions on some days. The daily average evaportranspiration is in general 10-30% less than the corresponding value given by the resident GHM.^ Sensitivity studies have been Conducted for: (1) Initial conditions and lower boundary conditions. The effect of different initial soil moisture conditions in the surface layer persists approximately one week, while in the lower layer at least as long as the operational period. Different lower boundary conditions only produce minor effects. (2) Vegetation density. For extreme cases of desertification and afforestation, the effects of the vegetation density on surface temperature, evaporation, sensible heat and soil moisture are most significant. (3) Canopy resistance. Mainly the daily averaged grid evapotranspiration and the soil moisture content are effected. (4) Surface albedo. Albedo exerts a large effect on the energy balance and thus temperature variation. (5) Depth of root zone and root density distribution. The effects from thse two parameters on the grid evaporation, sensible heat, moisture content and temperature are small. ^

EFFECTS OF SOCIAL LEARNING AND ILLNESS MODELS OF ALCOHOL ABUSE ON HELP-SEEKING BEHAVIOR
MOSS, STEPHEN BLAINE
Eighty-five percent of severe alcohol abusers never receive treatment for their problem. This study compared the effects of Social Learning and Illness models of alcohol abuse on facilitating acknowledgement of a problem and encouraging attitudes and behaviors that might lead to seeking treatment. It was hypothesized that the Social Learning model, emphasizing the psychosocial factors of alcohol abuse, would more effectively facilitate appropriate help-seeking attitudes.^ College students who reported high and moderate alcohol abuse were educated in one of these models. Independent variables included subsequent questionnaire responses and unobtrusive behavioral measures. Prior alcohol beliefs were found to be easily manipulated and impacted minimally on the findings. Evidence suggested that Subjects educated in the Social Learning model were better able to acknowledge that they were too dependent on alcohol and that they would have difficulty cutting down their drinking.^ Illness subjects were found to be more willing to admit needing help and less embarrassed about seeking treatment; less inclined to assign fault to the abuser; and more interested in considering seeking further information. More educational brochures and announcements for an upcoming seminar were also taken by Illness subjects. Post hoc analyses consistently supported the superiority of the Illness model in encouraging help-seeking.^ To explain the superiority of the Illness model in encouraging more adaptive help-seeking attitudes, intentions, and behaviors, it was suggested that the Illness model was less threatening to one's self-esteem, was a simpler construct to understand, and aroused more motivating fear. Future research should address the value of the Social Learning model in facilitating the acknowledgement of a drinking problem and test these findings in appropriate populations. ^

PROTEIN AND RNA SYNTHESIS INHIBITION BY VESICULAR STOMATITIS VIRUS: AN ANALYSIS OF THE VIRAL COMPONENTS REQUIRED FOR INHIBITION (TRANSLATION, TRANSCRIPTION, INFECTION, TARGET-SIZE, LEADER)
DUNIGAN, DAVID DEEDS
Protein and RNA synthesis are inhibited when VSV infects certain cells. UV-inactivation analysis of the virus indicates that transcription of two regions of the viral genome are required for efficient inhibition. The larger of the two viral products represents transcription of approximately 1500 nucleotides and may represent the N protein gene, while the smaller product is approximately 40 nucleotides long. The latter product is thought to be encoded at the 3'-proximal end of the genome.^ Two viral mutants have been shown to be deficient in the expression of the smaller transcription product and result in less efficient inhibition of both protein and RNA synthesis. Analysis of these mutants and the UV-inactivated wild-type virus have allowed for the establishment of conditions where the effects of either the large or the small transcription product can be observed independent of the other. This will allow for the correlation of a viral product with inhibition, and thereby establish the causative agent(s) of inhibition. The striking similarities of the inhibition processes for protein and RNA synthesis suggests that protein synthesis inhibition may be a consequence of RNA synthesis inhibition. A likely candidate for the small transcription product is the plus-strand leader RNA, a 47-50 nucleotide long transcript encoded at the exact 3'-end of the viral genome. However, analysis of this viral product in wild-type and mutant virus-infected cells indicates that neither protein nor RNA synthesis inhibition correlate to the presence of the plus-strand leader RNA.^ In vitro translation in VSV-infected cell lysates have been shown to reflect the synthetic activity of the whole cell. When the lysates are treated with eukaryotic initiation factors (eIF-2 and eIF-4B/4F), there is a stimulation of synthesis in the VSV-infected cell lysates and this stimulation seems to require expression of the majority of the viral genome. The eIF-2 specific stimulation is quenched when cell extracts are pre-incubated with sera from patients having the Lupus auto-immune antibody to the La protein. ^

THE MODELING OF GALVANIC CORROSION SYSTEMS USING NUMERICAL METHODS WITH PARTICULAR ATTENTION TO BOUNDARY CONDITIONS OF NONLINEAR POLARIZATION (ELECTROCHEMISTRY, FINITE-ELEMENT METHODS)
MUNN, RAYMOND SHATTUCK
The objective of this research was to develop a method for a-priori quantitative prediction of electrochemical potential and current distributions in systems of dissimilar metals submerged in an electrolyte, the motivation being mitigation of corrosion effects by material selection, geometric configuration, and cathodic protection design. Specificially, the method would employ existing numerical techniques for solving the Laplace equation, applying them in an electrochemical analysis technique for any specified geometry of electrodes having known electrode kinetics. Particular emphasis was placed on characterization of electrodic behavior using analytical expressions to represent the boundary conditions while retaining physical significance.^ A literature search examined analytical and graphical methods of the past half-century and numerical methods which began to appear in the latter 1970's. Herein, the partial differential equation governing the electric potential distribution in electrolytes was derived and unique boundary conditions representing complete nonlinear electrodics of submerged metals were developed. Modern numerical finite difference, finite element, and boundary element methods with applicability to modeling electrochemical phenomena were investigated.^ A particular finite element formulation was developed to preserve charge conservation, a required condition to include mixed potential theory in electrochemical modeling. The mathematics analogy between electrical and thermal conduction was identified and a commercially-available heat conduction computer program was selected and modified for electrochemical analysis by programming for the particular boundary conditions representing nonlinear electrode kinetics.^ The method of galvanic modeling and analysis was demonstrated by the several examples. One problem simulated one of simple geometry and idealized linear electrode kinetics previously solved exactly in the literature. Two problems with measured results for correlation were solved, one of a laboratory-scale experiment with two dissimilar metals submerged in the electrolyte, and a second of a macroscopic field problem of a shipboard seawater tank with the electrolyte enclosed by wetted metals. All three demonstration problems predicted electrochemical potential distributions in very good agreement with the exact solution or measured results.^ It was concluded that the electrochemical modeling method developed in this research embodies both mixed potential theory and full electrodic behavior of metal/electrolyte systems with demonstrated accuracy. ^

CLASSIFICATION OF TEXTURED SURFACES BASED ON REFLECTION DATA (IMAGE-PROCESSING, COMPUTER VISION)
TULPULE, SHARAYU
Recognition of surfaces is very important in computer vision. Color and texture of a surface are two key characteristics that influence the surface recognition process. Light reflected from a surface contains information about these two characteristics. The color of a surface determines how a surface reflects light of a specific wavelength, and the surface texture determines the amount of diffuse and specular reflection taking place from the surface.^ A statistical approach has been developed for classification of surfaces based on the spatial intensity distribution of light reflected from the surfaces. In this approach, a surface is modelled as a collection of mirror-like micro-facets oriented randomly with respect to each other. The random orientations of the micro-facets give rise to spatial intensity distribution of the reflected light. The reflected light field is characterized by a probability density function, which is used for deriving first and second order features. The first order features are the mean and variance of the reflected intensities, while the second order features are based on the spatial correlation between the reflected intensities. A correlation matrix is formulated based on the co-occurrence of two given intensities separated by a given angular distance. Two classification schemes based on maximum-likelihood and nearest-neighbor decision rules are implemented on the feature sets.^ Experimental results for the classification schemes are presented for a variety of sample surfaces. These include paper, cloth, felt, sandpaper, cork, crumpled and smooth aluminum foils, etc. The success rate of 80-100% has been achieved for the two classification schemes.^ In addition to these statistical features, other properties of textures such as gloss, contrast, roughness, etc., have also been measured from the reflected intensities. Parameters such as micro-facet slope function, micro-facet orientation function, etc., have been measured and used for predicting the statistics of the perceived texture. Techniques have been developed to reduce the computational burden associated with this reflection data based surface classification scheme in order to make it suitable for on-line operation. ^

A PERCEPTUAL AND ACOUSTIC STUDY OF THE EFFECTS OF SPEECH RATE ON DISTINCTIVE VOWEL LENGTH IN THAI
SVASTIKULA, M. L. KATYANEE
The difference between phonologically short and long vowels in Thai is mainly a temporal one, i.e., the relative durations of the vocalic segments. Yet such durational differences are also produced by changes in speaking rate. The present study explored the effects of speaking rate on 10 simple vowels of Thai. The first and second experiments were designed to see whether speech rates affects only vowel durations, or formant targets as well as durations. The results support only the effect on vowel durations. Acoustical measurements showed that formant-frequency targets were relatively unaffected by rate variations; however, vowel durations did vary significantly with change of rate. The vowel durations decreased with increase of speaking rate and vice versa.^ The third, fourth, and fifth experiments attempted to find out about the effects of speech rates on the perception of vowels of CV(V)C syllables. A potential perceptual problem would seem to be the confounding of temporal information for short and long vowels with temporal compensation between the rates of the carrier phrase and those of the key words. Experiments 3, 4, and 5 confirmed that listeners evaluated duration in the key words relative to the carrier-phrase rates. That is, the identification of a key word in its original carrier context was accurate; however, errors increased when there was a mismatch between the carrier rates and the rates of the key words. Not only the preceding-carrier rates but also the rates of the postcursive context influenced the vowel judgments for the key words. Thus, errors in vowel identification increased when only the postcursive rate was mismatched with the key-word rate, as compared with the identifications when the key word occurred in its original context. In addition, the influence of both preceding-context rate and following-context rate extends across words; it is not limited to a single syllable.^ For the phonological distinction between short and long vowels, the speaker of Thai takes considerable variation in speech rate into account, for both production and perception, in the processing of relative duration as the major phonetic feature. ^

A SYSTEMS ENGINEERING BASED METHODOLOGY FOR ANALYZING HUMAN BRAIN FUNCTION (EVOKED RESPONSES, STEADY-STATE EEG)
JUNKER, ANDREW MICHAEL
The objective of this work was to develop a systems engineering based methodology for quantifying effects of cognitive loading, and for modeling the human brain response in systems engineering terms. The visual-cortical response was selected as the input-output channel around which the methodology was developed. A steady-state input (a continuous sum of 10 sine waves) and a transient input (a train of pulses) were used for system stimulation. The human occipital EEG (surface electrodes at Oz and mastoids) was used as the cortical output. Analysis of input stimuli and output EEG potentials produced human visual-cortical describing functions (gain and phase) and remnant spectra (background EEG).^ A stimulus parametric investigation indicated that sensitivity to stimulus modulation depth is unequal across frequencies, and that relatively low stimulus intensity and depth of modulation are desirable to reduce response saturation.^ Comparisons between transient and steady-state stimulation revealed that both forms produced functionally related responses, suggesting that the visual-cortical response contains a measurable linear portion. Time domain amplitude changes corresponded to transient and steady-state gain changes.^ Consistent trends observed among subjects indicated that it is advisable to group subjects into two classes: alpha responders, and non-alpha responders. Classification would be based upon alpha band (8 to 12 Hz) responses in both remnant and gain curves.^ To investigate cognitive loading effects three tasks were utilized: manual tracking, grammatical reasoning, and supervisory control. Changes in visual-cortical response measures related to task loading were observed. With increased cognitive loading, alpha responders generally showed reductions in alpha band gain and remnant, and increases in beta band gain. Non-alpha responders showed increases in beta band gain only. Performance of supervisory control caused a reduction in phase lag for all subjects tested. Results revealed that individual differences must be accounted for.^ Some success in matching data with the model forms considered was achieved. Multipath modeling provided a promising approach for handling observed dropout points in the data. Model parameter values were found to relate to task performance scores. A model form based upon alpha and non-alpha classification should be individually applied. ^

THE HISPANIOLA DIASPORA, 1791-1850: PUERTO RICO, CUBA, LOUISIANA, AND OTHER HOST SOCIETIES (SLAVERY, RACE, SANTO DOMINGO)
MORALES, JOSE
The study examines the economic, political, and social repercussions of the Haitian Revolution (1791-1804) on the slaveholding societies of Puerto Rico, Cuba, Jamaica, Louisiana, Venezuela, and several cities in the United States. The focus is on the emigres who fled Hispaniola due to the events that enveloped the adjoining French and Spanish colonies. Special attention is paid to Louisiana and Cuba, both recipients of large numbers of emigres, and the effect of the Napoleonic invasion of Spain on both these societies. In both territories, the St. Dominguans augmented an already large population of free people of color. In Puerto Rico a similar situation occurred: the French contingent on the island was made up mostly of emigres from St. Domingue, and the free people of color were in turn the most numerous group within the French immigrant community.^ Chapter 1 discusses the Haitian Revolution and events that led to the first black republic in the Western Hemisphere. Chapters 2 and 3 look at the Hispaniola emigres in Louisiana, Cuba, Jamaica, and Venezuela, all very different social environments. The latter two were strongly affected by events in Europe. The common denominator in the host societies was the fear that the newcomers would "contaminate" the population with the ideals of the French Revolution. The fact that a large percentage of the emigres were people of color caused concern over a possible alliance with the slave population.^ Chapters 4 and 5 investigate the economic, political, and social development of Puerto Rico from the seventeenth century to the first decades of the nineteenth. Special attention is paid to population growth and the development of a cash-crop economy based on slave labor.^ Chapter 6 is a detailed examination of the municipality of Mayaguez, Puerto Rico, where the majority of Hispaniola emigres settled, and then engaged in sugar and coffee production and marketing. ^

EFFECTS OF AN ELECTROPOLYMERIZED INTERLAYER ON THE MECHANICAL PROPERTIES OF GRAPHITE FIBER/EPOXY COMPOSITES
CHANG, JEMEI
A uniform thickness, high molecular weight, acrylonitrile/methyl acrylate copolymer coating was applied onto graphite fiber surfaces through a batch electro-copolymerization technique. This technique was used to introduce a ductile interlayer of controlled composition and thickness between the composite fibers and matrix. Copolymers of methyl acrylate and acrylonitrile formed by this technique are random copolymers, with Tg's varying linearly with the copolymer composition from 14(DEGREES)C to 98(DEGREES)C. These copolymers have a fairly high number average molecular weight, in the range of 10('5) g/mol. Monomer reactivity ratios were determined, based upon free radical polymerization kinetics.^ Effects of the interlayer between the graphite fibers and epoxy matrix of a graphite/epoxy composite upon the composite mechanical properties were studied. The thickness and modulus of the interlayer and the bonding between the interlayer and the epoxy matrix were the three major parameters examined.^ It was found that interlaminar shear strength (ILSS) and impact resistance (IMPR) vary with the thickness of the interlayer, both showing the same general trend as the modulus of the interlayer changes. A thin interlayer, under 0.10 microns, improves the ILSS by relieving the thermal stress but also depresses the IMPR. An optimum thickness interlayer, between 0.1 and 0.15 microns, improves both ILSS and IMPR through stress relief and introducing shear failure during the fracture. At the maximum point, IMPR is improved about 30-40%, and ILSS is improved about 10-20% when compared with control samples. For interlayers thicker than 0.15 microns, ILSS and IMPR both decrease. The modulus of the interlayer does not show significant effects on the impact resistance due to high test speeds, all of the interlayers were glassy under impact conditions. The interlaminar shear strength decreases with the modulus owing to decreased stress transfer capability. Bonding between the interlayer and matrix, enhanced by acrylic acid, also improved the ILSS and IMPR. The single-fiber fragmentation test shows that good adhesion was achieved at both the fiber/interlayer and the interlayer/matrix interface.^ This study shows that it is possible to simultaneously improve both the interlaminar shear strength and impact resistance of composites by applying a suitable modulus and thickness interlayer at the fiber/matrix interphase.

VARIATIONS IN THE BANKING MULTIPLIER AND BASE MONEY: IMPLICATIONS FOR MONETARY POLICY IN THAILAND
CHATURONGKUL, THANISR
The problem of monetary policy implementation is how to manipulate policy so that the ultimate objectives can be achieved. Unfortunately, due to incomplete information about the structure of the economy, the monetary authorities' policy actions are unable to directly influence the ultimate objectives. The money supply, however, is one of the important economic variables that links policy instruments to the ultimate objectives. Thus, it is necessary for the policymakers to understand how the money supply is determined. The money-multiplier model helps explain the determination of the money supply because it incorporates both policy and nonpolicy factors that affect the behavior of the money supply.^ This dissertation addresses the usefulness of the money-multiplier model as a guide to monetary policy in Thailand. The model is developed based upon economic factors and the institutional structural of the Thai economy. To utilize this model as a guide to policy, the banking multiplier must be shown to be either stable or predictable or both. Thus, this dissertation provides empirical evidence on the predictability and stability of the banking multiplier. Predictability refers to the ability of a model to forecast the behavior of the multiplier. Stability means a strong relationship between base-money growth and money-stock growth. In addition, we examine the structure and activity of the Thai government security markets in connection with open-market policy.^ The findings of this dissertation provide support for the predictability of the banking multipliers. In regard to the stability of the banking multiplier, the bulk of the evidence exhibits a strong link between base-money growth and money-stock growth in the long run. In the short run, however, there is some evidence indicating the dominance of banking-multiplier movements in explaining money-stock movements. But, since the multipliers are predictable, then there is little reason not to adopt the money-multiplier model as a guide aid for monetary policy in Thailand. ^

DIGITAL HYDROLOGIC MODELING METHODS FOR WATER RESOURCES ENGINEERING WITH APPLICATION TO THE BROAD BROOK WATERSHED (CONNECTICUT)
ALLEN, STEPHEN JEFFREY
Methods are presented for the digital simulation of the hydrology of a small rural watershed. Development of the methods has been accomplished using the Broad Brook Watershed in northcentral Connecticut as a prototype watershed although the methods reported may be generalized and applied to other small watersheds. A computer model called the Small Watershed Hydrologic Analysis Model (SWHAM) is constructed by linkage of an existing one-dimensional Ground Hydrology Model (GHM) to an existing channel flow model through a newly created overland flow model. Methods for the creation of a digital database of watershed data including soils, land-use and land cover, and topography are presented using the MAP geographic information system (GIS), and the created database is then coupled with SWHAM. Meteorological data collected from several sources are used to drive SWHAM. Model output consists of the soil moistures, vegetation and soil temperatures, latent and sensible heat fluxes, and the basin discharge hydrograph. A sensitivity experiment is conducted using SWHAM to demonstrate the usefulness of the model in water resources engineering by assessing spatial variations in hydrologic inputs. ^

DEVELOPMENT OF A EUTROPHICATION MODEL OF AN ESTUARY DOMINATED BY THE MACROALGA ULVA LACTUCA (CONNECTICUT)
CURTIS, MICHAEL DUNCAN
Algorithms were written leading to the development and application of a water quality model describing the population dynamics of the macroalga Ulva lactuca. Model development assessed the fate and effect of the discharge from the Groton, Connecticut Wastewater Treatment Facility. Important biological and chemical processes researched for application to this model were Ulva sporulation, nutrient cell quota growth kinetics and nutrient uptake. Temperature related growth and the growth response of Ulva to ambient light intensities were researched and implemented as found in the literature.^ Data collection proceeded in three related efforts over a four year period in Mumford Cove, Groton, Connecticut. The data gathered from this site served as the calibration and verification data sets for model application. Extensive data reduction as well as interpretation of data seen in the literature allowed the development of the kinetic structure of the water quality model. The Water Analysis Simulation Program was used as the base hydraulic portion of the model.^ Nutrient cell quota kinetics were successfully developed and applied. Nitrogen cell quota calibration was accomplished with input data calculated from published reports while phosphorus cell quota parameters required some adjustment prior to model completion. Ulva sporulation was shown to be a highly significant process in the nutrient and Ulva population dynamics. Sporulation represents a major pathway for nutrient introduction to the sediments. Additionally, in Mumford Cove, sporulation is a significant source of summertime Ulva population decay. ^

FOOD OF THE GODS: CACAO AND THE ECONOMY OF THE PROVINCE OF CARACAS, 1700-1770 (VENEZUELA)
PINERO, EUGENIO
This study examines the economy of Caracas Province during the eighteenth century using the staple thesis model of economic development. The staple of the region was cacao, produced on plantations, and exported to the markets of Mexico, Spain and Europe. Of particular importance was the creation of the Caracas Company in 1728, formed for the purpose of shipping cacao to the Spanish market and to prevent contraband trade. It failed in the latter goal due to the incursions of Dutch traders who were aware of the profitability of the cacao trade to Europe.^ The export of cacao from Caracas had an impact upon the regional economy in many ways. Linkages with timber and cattle producers, for example, were established. In one northwest city of the Province, San Felipe, Indians not only worked on plantations, but also proved to be successful as small farmers. They sold their cacao in the port of Puerto Cabello along side larger plantation owners. Thus, San Felipe offers an example of the multiplier effects from a plantation, and the manner in which ties were forged between colonists, internal and coastal cities, metropolis and the international market.^ Quantitative analysis is employed to understand various aspects of the 18th century cacao trade from Caracas Province to Veracruz and European ports of entry. ^

PREPARATION AND CHARACTERIZATION OF IRON CATALYSTS ON PILLARED CLAYS AND PHOSPHORUS CONTAINING MOLECULAR SIEVES
KOSTAPAPAS, ATHANASIOS
Mossbauer, EPR and UV-visible spectroscopic techniques has been used to study the environment of ferric Fe $\sp{3+}$ ions doped into alumina-pillared bentonite clay materials. Results suggest that the ferric ions can preferentially occupy different sites in the clay depending upon synthetic conditions. In addition, evidence is presented for the Fe $\sp{3+}$ ions being coordinated within the pillar itself. N-decane hydrocracking experiments indicate that the catalytic activity and selectivity of these materials depends upon the location of the ferric ions within the clay. During catalytic reaction the chemical state of the iron changes as indicated by Mossbauer spectroscopy and X-ray diffraction data, after catalysis, indicate that these materials are not thermally stable.^ In addition, metallic iron catalysts were prepared on aluminophosphate and silicoaluminophosphate molecular sieves vis microwave decomposition of organometallic precursors in an argon plasma. Mossbauer spectroscopy was employed to characterize the prepared catalysts and evidence exists for the preparation of small metallic iron particles, in the superparamagnetic region. Furthermore, results obtained provide evidence which suggest that the state of dehydration of the catalyst support, the surface chemistry and type of support are important factors to be taken into consideration when one investigates the feasibility of preparing zerovalent small metal particles on supports via microwave discharge methods. Experiments suggest that the higher the acidity of the surface, the less likely the possibility of small metal particle preparation on surfaces. ^

Knowledge-based classification of Landsat Thematic Mapper digital imagery
Civco, Daniel Louis
An innovative approach to identifying land use and land cover categories through computer-assisted analyses of digital satellite remote sensing image data is presented. The technique is based on the subfield of artificial intelligence known as expert systems, commonly referred to as knowledge-based systems. The methodology developed embodies expert image analyst rules and heuristics in a knowledge base which is used to classify regions of a Landsat Thematic Mapper image. Expert knowledge about and image attributes from spectral, spatial, and temporal domains are addressed. The procedures for image and ancillary data preprocessing, knowledge acquisition, knowledge-based image analysis, and traditional image classification are discussed.^ Both the deterministic knowledge-based image analysis approach and the traditional statistical maximum likelihood approach were applied to multidate Landsat Thematic Mapper digital imagery to derive land use and land cover information. It was found that a knowledge-based approch to the classification of specially-processed, digital remote sensing imagery, coupled with spatial information, produced results superior, in terms of accuracy and visual comprehensibility, to those achieved through conventional per-pixel, supervised classification of multispectral data alone. It was illustrated that the knowledge-based method developed permits the inclusion of heuristics and decision criteria not possible in the strictly numerical, algorithmic approach. Because of the success of this prototype knowledge-based image analysis system, and because of its parallelism with human visual image analysis processes, additional research into this area is recommended and briefly discussed. ^

THE EFFECTS OF COMBINED SCALING TECHNIQUES ON THE PSYCHOMETRIC CHARACTERISTICS OF A RATING SCALE
THOMAS, RICHARD DONALD
This study examined the psychometric characteristics of several variations of a rating scale that was developed as a part of a selection and promotion project for the Police Department of Peoria, Illinois. The rating scale was specifically for the purpose of rating the incumbent sergeants in the department. The sergeants were to be rated by their supervisors.^ Supervisory ratings are among the most common indices of performance in settings such as this. Since this data is often critical to promotion decisions, psychometrically sound rating instruments are extremely important.^ A combination of rating scale development techniques was used. Characteristics important to the job of sergeant were solicited from the incumbent sergeants and the administrative staff of the department. These characteristics were edited, assigned to a rating instrument and sent back to the sergeants and administrators. They were then asked to rate each characteristic on the continua of both importance to the job and how often the characteristic is needed in the job. The items were arranged by rank order of importance and used as a pool to create two separate rating scales.^ The first scale consisted of the simple assignment of the items to a 52 item Likert type scale. The second scale was created by selecting 23 items that evenly spanned the importance continuum. These scales were then used by supervisors to rate the incumbent sergeants. Both of these scales were scored using a simple summated procedure and using a procedure that attributed weights to each item equal to their median importance ratings.^ Cronbach's Alpha, the skewness index, and validity coefficients were calculated for each variation of the rating scale. (Ratings were correlated with a paper and pencil test developed to measure job knowledge to determine the validity coefficient).^ Results indicate that the short weighted versions of the rating scale provide ratings with significantly superior validity data. ^

CHAIN GROWTH IN THE FISCHER-TROPSCH SYNTHESIS
STOCKWELL, DAVID MATHESON
Methanation and hydrocarbon synthesis from CO and H$\sb2$ was studied using 10 wt% Ni/Al$\sb2$O$\sb3$ and 10 wt% Fe/Al$\sb2$O$\sb3$ catalysts at 1 atm. Transient responses to the switches between various feed mixtures, especially isotopically labeled feeds, to a gradientless microreactor were used to obtain information on the amounts and reactivities of intermediates on and in the catalysts. On Ni/Al$\sb2$O$\sb3$, about 0.5 monolayer of adsorbed CO and smaller amounts of C are present during reaction. Infrared and CO/D$\sb2$ suggest that significant amounts of CH$\sb{\rm x}$ (x = 1-3) are not present. Chain growth experiments with $\sp{13}$CO/H$\sb2$ indicate that the hydrocarbons are formed primarily from C, but the results also indicate that the process is not fully understood. All steps in methanation and chain growth appear to be fast, except for the limiting steps CO$\sp\* \to$ C and C $\to$ CH. On Fe/Al$\sb2$O$\sb3$, methanation and chain growth occur via CH, with all steps except the initial conversion of CH apparently being fast. Bulk iron carbides and an inactive form of carbon, different from C on Ni/Al$\sb2$O$\sb3$, do not participate significantly. The CH deactivates slowly with time on stream; only a small portion produces most of the products after 2 h on stream.^ Other work concerned H$\sb2$ chemisorption on various supported metal catalysts. Using TPD, an unusual spike was found after low temperature adsorption on Ru/SiO$\sb2$. The activated adsorption of H$\sb2$ on Fe/SiO$\sb2$, Fe/Al$\sb2$O$\sb3$, Ni/AlO$\sb3$, and Rh/TiO$\sb2$ was compared. It was suggested that, by analogy to titania-supported metals, the origin of the activation barrier may lie in a decoration phenomenon. It was proposed that SiO$\sb{\rm x}$ and AlO$\sb{\rm x}$ species may have been derived from small amounts of support which dissolved in the impregnating solution. ^

Texture and ornament in the music of Claude Debussy
Friedman, Edward Arthur
Motion is the central metaphor available to analysts' attempts to appreciate or account for musical activity. Yet, because the music of Claude Debussy is in so many ways puzzling to critics, a great deal of commentary neglects the question of his unique way of creating musical motion. The aim of this study is to show that Debussy did not reject motion in favor of color; rather, a new concept of musical motion generated (among other things) a new kind of color.^ This study focuses on a group of selected songs and piano pieces published by Debussy over a period of about twenty five years: "Passepied" (Suite bergamasque), "Clair de lune" (Suite bergamasque), "La flute de Pan" (Trois Chansons de Bilitis), "Clair de lune" (Fetes galantes, 1st collection), "Mandoline", "C'est l'extase" (Ariettes Oubliees), "Reflects dans l'eau" (Images pour piano, 1st set), "Feuilles mortes", "General Lavine--eccentric", and "La terrasse des audiences du clair de lune" (all from Preludes, 2nd book), "Et la lune descend sur le temple qui fut" (Images pour piano, 2nd set), plus the first movement from the Sonata for Flute, Viola, and Harp.^ Chapter One is concerned with the nature of Debussy's conception of tonality, a circumscribed tonality of reduced cadential obligations. The harmonic surfaces are largely the product of mixed modalities, tonal allusion (a lack of dependence on cadential inevitability is accompanied by conventional relationships in foreign keys without traditional tonicization), and harmonic sequence.^ Debussy's harmonic surfaces are ultimately to be characterized as ornamental in that chromatic melodic motion occurs without significant chromatic harmonic motion. Chapter Two is an examination of ornamental textures and how they contribute to harmonic definition. Underlying progressions are characteristically expressed as successions of textures in which the importance of surface harmonic progressions is in many ways subordinate to other elements such as pedals, linear motion, and chordal arpeggiation.^ Harmonic, linear, and textural shapes often produce a tonal problem or puzzle. Chapter Three shows the essential formal consequences of their subsequent treatment in the articulation of both a tonal structure and a thematic plan. ^

Investigation into the use of glassy gelatin beads as a swelling-controlled drug delivery system
Klech, Cathy Marie
The fundamental principle of a swelling-controlled drug delivery system is nonFickian transport of solvent into a glassy polymer matrix. The velocity of the advancing solvent front can determine the drug release rate.^ Initial stages of the development of gelatin as a swelling-controlled drug delivery system required the identification and characterization of influential parameters associated with the swelling behavior of the glassy gelatin matrix. For example, swelling studies using different solvents demonstrated a size selectivity, in which a known solvent for gelatin could not penetrate the glassy matrix due to its large molecular size. Also, by the estimation of effective crosslink density, the distinction was made between chemical and physical crosslinks.^ Two moving boundaries are associated with this swelling system, the penetrating water front and outer swelling gelatin front. Both boundaries were measured directly with an optical microscope as a function of time. Interestingly, the water front profile exhibited three distinct regions: an initial square root of time region (Fickian), a steady state velocity region (apparent Case II transport), and a final region where the front accelerated near the bead's center (apparent Supercase II transport).^ Subsequent studies focused primarily on variables that affect the water front steady state velocity which include: initial size of a dry bead, crosslink density, solvent-induced stress on the glass-gel interface, and most importantly, the efficiency in molecular packing of the glassy matrix (swelling history). A correlating function was then proposed on the basis of dimensional analysis and experimental observations.^ Incorporation of the model drug, isoniazid (INH), into gelatin beads altered the structure and hence swelling behavior of the glassy matrix. Plasticization of gelatin chains by INH was postulated as the primary factor for inducing the increase in water front velocity for beads with greater drug content. Fractional release rates were studied as a function of crosslink density, drug load, and device size, in addition to moving boundary analysis. These combined results provide evidence that INH release rates were dependent on the water front velocity. ^

HUMAN AUDITORY AND VISUAL CONTINUOUS EVOKED POTENTIALS
GOLDMAN, ZVI Z
The motivation for this research was to develop an evoked potential methodology for non-invasively monitoring the auditory and visual sensory channel engagement and interaction (A x V) in humans. Sensory interaction was concluded whenever response variations of one sensory channel could be attributed to parameter changes of an additional stimulus, simultaneously presented to another sensory channel. This study adapted the phase-lock technique in characterizing the stimulus parameter-space of the A x V process.^ The stimuli consisted of sinusoidally modulated, 100% amplitude-modulated tone and spot-light signals. The independent variables were the stimulus modality (audio, visual or both), Modulation Frequency (MF, 5-61 Hz), intensity (24 dB range) and subject attentiveness. Continuous Evoked Potentials (CEPs) were recorded from Cz-A1 (auditory) and Oz-A1(visual) sites. The CEP dependent variables were the magnitude and phase of the evoked potential component phase-locked to the stimulus fundamental or 2nd harmonic MF. The CEPs were characterized in terms of their magnitude, phase and latency Modulation Transfer Functions, background EEG, repeatability, linearity, and stimulus intensity and subject attentiveness dependencies. Finally, the A x V process was assessed on a selected stimulus parameter-space.^ Most of the results were derived from two MF regions, "Beta" (16-25 Hz) and "Theta" (5-6 Hz). Delays and latencies of Beta and Theta CEPs were estimated from linear models fitted to the magnitude data; 30-40 msec and 60-70 msec (Beta), and 50-60 msec and 200-240 msec (Theta), respectively. Responses elicited from these MF regions were consistent, exclusively evoked, repeatable and easily detectable. In comparison to the auditory CEPs, the visual CEPs were associated with higher signal/noise magnitude ratio, higher inter-subject variability and lower intra-subject variability.^ Genuine A x V effects of 5.5 dB magnitude-gain and 40 degree phase-shift were found. Magnitude inhibition and phase lag were generally associated with, and induced by, the short-latency Beta MF region. Magnitude data was primarily affected by "Internal" parameters (intra-modality stimulus intensity or MF) and phase data by "External" parameters (cross-modality stimulus intensity). Attention allocation did not play a major role. ^

Creating paradise: The Cuban-American struggle for control of Cuba's economic development, 1944--1952
Figueroa, Javier
This study examines the Cuban-American struggle to control Cuba's postwar economic development in the period 1944-1952. Cuba emerged from the war in a strong position to negotiate with the United States. The Americans required sugar and Cuba had plenty of it. When the United States suggested to Cuba's President, Ramon Grau San Martin, a strategy for economic development that de-emphasized the sugar industry and instead recommended industrial growth and a suitable climate for foreign investment, including restraints upon labor, the Cuban government refused to comply. Cuba needed to sell sugar and market conditions were favorable for sales.^ But by 1947 circumstances had changed. The United States no longer needed as much sugar from Cuba, so Havana was forced to modify its stance. When the new Cuban President, Carlos Prio Socarras, realized that the Americans were no longer willing to grant its sugar petitions, he began to look for new markets. At the same time the Cubans drafted a policy of industrialization. Prio also opened Cuba's doors to military links with the Americans, an initiative which the United States viewed as fundamental to achieve internal security. President Prio, however, resisted American pressures to modify his labor policy which tolerated strikes and provided for higher wages. He needed the political support of the workers and refused to take measures to restrict them. Employers criticized him and the United States lost trust in the Cuban President. The military coup orchestrated by Fulgencio Batista on March 10, 1952, found Prio politically weak. Cuban capitalists and the Truman Administration supported the new regime. They turned to Batista in the hope that a strong hand could help them achieve their goals. The United States and Cuba were finally in basic agreement on the strategy to develop the Cuban economy.^ This study is based upon archival research at the United States National Archives, the Harry S. Truman Library, and the University of Florida Libraries, as well as upon contemporary Cuban and American documents and publications. Interviews with persons who participated in the events also helped in reconstructing the Cuban side of the story. ^

A study of the relationship between cross-cultural training, the scale to assess world views, and the quality of care given by nurses in a psychiatric setting
Cunningham-Warburton, Patricia Ann
This research was designed to examine the relationship between training in the use of the Scale to Assess World Views and transcultural nursing and client perception of nurse caring. The Scale to Assess World Views is a cultural assessment tool that was used by nurses in the study to identify the values and beliefs of clients. The study focused on individual value orientations with an emphasis on within group variation. Using the assumption that individual variation within cultures is a significant factor, this study focused on variant value orientations rather than dominant value orientations. A second assumption posits that each nurse-client interaction is, to a certain degree, a cross-cultural encounter. In addition to client perception of nurse caring, client perceived empathy was also investigated.^ The sample consisted of two groups: nurses and hospitalized clients. A combination of two designs was used: a pretest postest control group design and a postest only control group design. Nurse participants were randomly assigned to the experimental or control group. All nurses were pretested on empathy. At the completion of the experimental treatment, all nurses were postested on empathy. One month after completion of postesting, nurses in the experimental group began to use the Scale to Assess World Views with clients. Over the next three months, data were collected from clients on nurse caring and empathy.^ Data were analyzed using the following procedures: one-way analysis of variance, repeated measures analysis of variance, and the Pearson Product-Moment Correlation Coefficient. Significance was determined at the.05 level.^ Four null hypotheses were tested. Three were rejected. There was a significant difference between groups on client perceived nurse empathy and nurse caring. There also was a significant interaction between time of testing and group membership on empathy scores. There was no correlation established between nurses' self-rating of empathy and client perception of nurse caring.^ The results suggest that cross-cultural training and the use of the Scale to Assess World Views can enhance quality of nursing care. ^

Characteristics of the effective clinical teacher of nursing as perceived by students and faculty
Murphy, Angela Ciolfi
It is presumed in the relevant literature that the characteristics of the effective classroom and clinical teacher of nursing are the same. This study sought to determine the accuracy of this presumption by surveying the perceptions of senior nursing students and their faculty regarding the characteristics of the classroom and the clinical teacher. It also sought to generate descriptive theory by identifying essential characteristics of the effective clinical teacher of nursing. Descriptive theory that can yield hypotheses for further study in this area.^ This research was conducted in two phases. The first phase established validity and reliability measures on a modified version of Sylvia Brown's Clinical Teacher Characteristics Instrument. The instrument was administered to five Faculty raters and 137 senior nursing students in a four-year publicly supported baccalaureate nursing program in Rhode Island. In the second phase, the instrument was utilized to survey the perceptions of a population of 581 senior nursing students and 134 faculty in ten publicly supported university nursing programs in five New England States. Validity and Reliability measures of the instrument were again established.^ Four null hypotheses were proposed that anticipated no significant difference in: (1) the student's perception of the characteristics of the effective clinical vs. the classroom teacher of nursing; (2) the faculty's perception of the characteristics of the effective clinical vs. the classroom teacher of nursing; (3) the student's vs. the faculty's perception of the characteristics of the effective classroom teacher of nursing; and (4) the student's vs. the faculty's perception of the characteristics of the effective clinical teacher of nursing. After Factor Analysis and Discriminant Function Analysis all four hypotheses were rejected.^ Both students and faculty perceived the characteristics of the classroom teacher and the clinical teacher of nursing to be different. In addition, the faculty perceptions of the characteristics of the classroom and the clinical teacher of nursing differed from those of the students. A revised version of Brown's instrument was developed, and the first step of descriptive theory regarding the clinical teacher of nursing was established. ^

The Edwardses: A ministerial family in eighteenth century New England
Minkema, Kenneth Pieter
Jonathan Edwards, today hailed as the foremost colonial American thinker, has emerged as an important figure in the rewriting of New England history. Edwardsean scholars are revising the image of him as an isolated genius by looking at him within a cultural context, attempting to discover what he had in common with his times. This dissertation seeks to extend this approach by exploring for the first time the inter-connectedness of the three generations of the Edwards family of pastors, one of the most prominent families in eighteenth-century New England, showing how each generation influenced the next.^ The collective careers of Timothy Edwards (1669-1758), Jonathan Edwards (1703-1758), and Jonathan Edwards, Jr. (1745-1801) reflect a period in which New England, not to mention the thirteen British American colonies, underwent tremendous change. Yet, the transformation of New England thought and society was accommodated and guided by vital strains of Puritan thought, piety, and temperament. Much of that experience is illuminated through the Edwards family.^ Recent historians have emphasized the persistence of Puritanism in opposition to the traditional "declension" model, which posits that seventeenth-century piety and doctrine had all but disappeared by the early eighteenth century. The Edwardses typified their fellow provincials in retaining Puritanism while addressing contemporary issues. In particular, this study explores the Edwards' reliance on the comprehensive Puritan construct of the covenant theology, which addressed the terms of national prosperity, church maintenance, and individual conversion; the role of family culture in inculcating religious persuasion; the personalities of each of the Edwardses and how their temperaments, generally not as exalted as their intellects, affected their careers; and their often ambivalent relationships with their congregations within the broader context of lay-clerical relationships in New England.^ But the Edwardses were not passive receptors of teachings handed down from the past. Their determination was to make Calvinism relevant and engaging. Their reassertion, reinterpretation, and refinement of Puritan tenets not only reflected but also instigated changes in evangelical techniques, pulpit rhetoric, and religious psychology, and provided fuel for late eighteenth-century and nineteenth-century debates in philosophy, social ethics, and ecclesiology. ^

An analysis of selected variables that predict persistence of re-entry women in an external degree baccalaureate nursing program
Rucki, Sheila Quinn
While many re-entry women begin baccalaureate study in nursing, little is known about phenomena that contribute to persistence in higher education. Little research has been conducted on the external degree baccalaureate nursing program as an alternative to traditional study.^ The purpose of this study was to identify a set of variables indicative of group membership as a persister or non-persister of a sample of re-entry women enrolled in an external degree program, specifically, the New York Regents Baccalaureate Nursing Program, and to examine the strength of these variables in several contexts. Self-report data were collected regarding life situation, employment and education variables, along with data on factors indicative of satisfaction with degree requirements, interpersonal supports, external study issues and goal attainment. These variables were cast as possible predictors of persistence of students enrolled in this program. Achievement data was added to this list for a New York State sub-sample.^ This was a survey research project with an ex post facto design. The population for the study was comprised of 800 participants from the external degree program. An instrument developed by the investigator was used to collect data.^ Discriminant function analysis was applied to data for the sample. Findings revealed the following as significant predictors of group membership as a persister or non-persister: Factor 1 (Degree), NLN Accreditation Status, NLN Decision and Factor 2 (Interpersonal Support). Post-hoc tests of differences between two means for Factors 1 and 2 were highly significant. Post-hoc Chi-Square Analysis of NLN Decision and NLN Status were not reported as significant, suggesting interaction status for these variables.^ A second discriminant analysis exercise was employed for analysis of the New York State sub-sample. The following emerged as significant: Factor 4 (Goal Attainment), Years Elapsed, Factor 3 (External Study Issues), Credits Accrued, Factor 1 (Degree) and NLN Decision. Post-hoc tests of mean differences on Factors 1 and 4 yielded significant results. Post-hoc Chi-Square Analysis of differences between credits accrued and years elapsed were also significant. Replication of the study with more and different predictor variables was recommended for further study. ^

La barbarie en la sangre: Determinismo y significaci\'on en el ``Facundo''
Saez, Nacunan Lautaro Fernando
Sarmiento aspires to a "scientific" historiography. He maintains that direct observation, free from the distortions of rhetoric, would make possible to discern hidden, unsconscious principles behind individual people and actions. He realizes, however, that those very transcendental principles make rhetoric unavoidable. "Meaning" acquires thus a new dimension. Earlier historians were concerned with the meaning of history, with the finality of human actions that made history comprehensible. Sarmiento, on the contrary, is preoccupied with meaning in history, with the hermeneutics of historiography. He contends that because there is a transcendental sense, our knowledge is conditioned and subjective.^ Meaning is, then, at once a condition of and a threat to the rationality and predictability of time. Sarmiento implies that the history of his country is incomprehensible on the surface because it is determined, at a deep level, by the conflict between civilization and barbarism, a conflict which is not directly observable. Paradoxically, Sarmiento avoids defining the two principles. Therefore, criticism has reproached him for being nebulous and unsystematic. I argue, however, that the logic of eschatological determinism prevents him from giving univocal definitions. It he were to conclude, for example, "barbarism is oppression, civilization is democracy," he would imply that ultimate determination comes from freedom and oppression, not from civilization and barbarism. The system, because it is transcendental, must be relativistic.^ History reveals itself through signs, but signs are inadequate. Indeed, they are exactly the opposite of their referent. Seeking to write an unrhetorical history, Sarmiento published Facundo in a system of simplified spelling, believing that, if each letter corresponded to a sound, everyone could easily read and write. Universal literacy would almost automatically bring about democracy. In a literal sense, then, phonetic spelling represented educated consensus, civilization. In another sense, it represented a new cognitive disposition, a system of signs which were arbitrary but also decodable, since they exist in discrete, phonetic opposition to reality. Writing would then dispell meaninglessness by making it predictable. If Sarmiento could explain barbarism, it would vanish. ^

On government
Uriagereka, Juan
This thesis explores the notion government within the Principles and Parameters model of Universal Grammar. Following Chomsky's proposals in Barriers, government is defined recursively, the induction step in terms of the notion barrier. This is used to account for phenomena that fall under (i) Case Theory, (ii) Movement operations and representations, (iii) Binding Theory.^ Barrier is defined in terms of maximal functional projections headed by a morphologically represented category. The process of Head Incorporation, since it leaves beind a non-morphological element (t), eliminates a class of potential barriers. Another class is eliminated by preventing the functional projection from taking a specifier, which results in the projection being non-maximal. Given this relativization, the same notion barrier can be used in different sub-systems.^ Analyses are presented of phenomena within the Romance Languages, English, Basque, and others, all of which involve government: Case assignment, Subjacency parameters, Multiple Questions, Modification, Cliticization, et cetera. Apart from simplifying considerably the Theory of Barriers, an attempt is made to derive Binding Theory from government-related notions, such as the Empty Category Principle and Incorporation. ^

Predictors of performance on NCLEX-RN for baccalaureate nursing graduates
Schiffman, Rachel Fredette
The relationship between selected demographic and academic predictors of performance of baccalaureate nursing graduates on the National Council Licensure Examination for Registered Nurses (NCLEX-RN) is the focus of this study. Also, an optimal time for identification of an at-risk group is presented. The current nursing shortage, which is exacerbated by declining enrollments and examination failure make it imperative to identify characteristics of successful baccalaureate nursing graduates in order to attract qualified candidates and retain them. An information-feedback systems framework proposes that characteristics of individuals prior to entry to college and the nursing program as well as their achievement in the nursing program are determinants of performance on the licensure examination. The sample is 501 nursing graduates from the classes of 1982 through 1986 at a public college in the Northeast. A double cross-validation strategy demonstrates the stability of the regression equation with correlations of.65 and.69 between actual and predicted NCLEX-RN scores. The hierarchical regression analysis results in an equation with five significant predictors and accounts for 52.4% of the variance in NCLEX-RN scores. The significant predictors are two entry characteristics, age and SAT-verbal score, and three nursing program variables, GPA's of the nursing courses second semester sophomore year, first semester junior year, and second semester junior year. The optimal time for predicting an at-risk group is the end of the junior year. The regression equation from this time classifies all but five of the cases known to have failed the examination in the at-risk group; however, this groups also includes a large number of cases known to have passed NCLEX-RN. Therefore, the classification is correct for only 25.8% of the at-risk group. The implications of the study findings include: first, to identify an at-risk group for further screening; second, to assess and strengthen the congruence between the curriculum and the content of the licensure examination; third, to employ causal models in future research; and fourth, to include variables from other domains in future research. ^

How nurse managers contribute to registered nurses' perceptions of the workplace reality
Caramanica, Laura Jude
The purposes of this investigation were: (1) to gather data on how nurse managers contribute to registered nurses' perceptions of the workplace reality and (2) to develop knowledge that will help hospitals obtain and retain registered nurses.^ Specifically, the research questions were: (1) How do nurse managers contribute to registered nurses' perceptions of the workplace reality? (a) How do nurse managers in the course of relating to their staff contribute information through social cues? (b) How do nurse managers in the course of carrying out their role and responsibilities enact the objective reality of the workplace?^ The primary methodology adopted for this investigation was grounded theory developed by Glaser and Strauss. Interviews with nurse managers and their staff (registered nurses), observer field notes, and review of selected memos and documents were combined to arrive at how nurse managers contribute to registered nurses' perceptions of the workplace reality. A total of five nurse managers and five registered nurses participated in the study.^ Data analysis yielded three categories of how nurse managers contributed to registered nurses' perceptions of the workplace reality: nurse manager as standard bearer, diplomat, and change agent. Based on these categories and their properties, an explanation of both aspects of the research question was obtained.^ Nurse managers and registered nurses identified that nurse managers play a significant role in the socialization of their staff. They influence their staff greatly during their initial contact (timing) with them and this appears to have a lasting effect over time.^ As diplomats, nurse managers strive to achieve a mutual level of understanding with their staff. They provide the organization's warmth; filter information to make it more acceptable for staff; and protect the organization's image.^ This study provides data to support that how nurse managers view change dictates how they implement the change process. As change agents, they use their authority to govern the workplace of their staff. Additionally, nurse managers have difficulty implementing a change they do not believe is consistent with the purpose of the organization.^ The findings suggest that nurse managers serve as key participants in their organization who enact the workplace reality through the process of attention and interpretation of the social construction and interaction processes of their organization. ^

The synthesis and characterization of dithiolenes with intense electronic transitions in the Near-IR region near 1.5 microns
Yoon, Dong Ihl
One of the most unusual properties of dithiolene complexes is their intense electronic transition in the VIS and Near-IR regions of the electromagnetic spectrum. To investigate the possibility of utilizing dithiolenes as dyes for the purpose of Q-switching NIR lasers, this work concerns the synthesis and characterization of new dithiolenes with intense absorption in the region between 1.3 and 1.5 $\mu$. The first task was to define the design of new ligand systems which incorporate several structural features necessary to shift the adsorption band into the lower energy range. An analysis of these structural features suggests the dithiolenes with amino-substituted acenaphthene and phenanthrene ligands as the best choice to reach 1.5$\mu$. Therefore, the target compounds of this thesis are bis(3,6-bis-diethylaminophenanthrene-9,10-dithiolato)nickel, bis(1,12-diethyl-1,2,3,4,9,10,11,12-octahydro-1,12-diazapentaphene-6,7-dithiolato)nickel and bis(1,4,9,12-tetraethyl-1,2,3,4,9,10,11,12-octahydro-1,4,9,12-tetraazapentaphene-6,7-dithiolato)nickel. The synthesis of these materials was accomplished. It was also deduced from the experimental results that this approach is reaching the limits to which donor-substituted benzenoid aromatics can be expected to shift the low-energy dithiolene absorption. ^

Characteristics related to high levels of creative/productive behavior in secondary school students: A multi-case study
Delcourt, Marcia Agnes Balnanosis
This study investigated characteristics related to creative/productive behavior in adolescents. These were students who consistently engaged in first-hand research of self-selected topics. The topics were related to activities both within or outside of school. Selection of students for this study was based upon the quantity and quality of their projects. Therefore, giftedness was viewed as being manifested in performances. In contrast to a static perspective of the gifted individual, this conception of giftedness focuses upon the dynamic nature of gifted behavior.^ Creative/productive behavior was under investigation for two main purposes. First, to describe the phenomenon, showing that students can be producers of information as well as consumers. Second, to examine student behaviors, forming a more specific set of personal and environmental characteristics related to creative/productivity.^ The sample consisted of 18 students in grades 9 through 12 from 4 sites in the Northeast. All sites were located in typical high schools as opposed to special schools for the gifted. These schools conducted programs for the gifted, focusing upon the development of creative/productive behavior in students.^ A qualitative analysis was conducted utilizing triangulated methodology of data sources and methods. Focusing upon student perspectives, sources constituted the family, the school, and the individual. Methods included document analysis, questionnaires, and a student interview. Document analysis was employed to collect school-related data pertaining to the program for gifted education and to the student's academic record. Parents responded to questionnaires about family background and their perspectives of their child's creative/productive behavior. Each student responded to several assessments of personality, a questionnaire regarding their creative productivity and a series of interview questions. A microcomputer program was employed for sorting and retrieving coded text data.^ Characteristics relative to family background, educational experiences and individual characteristics were analyzed. Results revealed that these students do exhibit characteristics similar to those of creative/productive adults, that these students can be producers of information as well as consumers, and that their learning processes merit closer attention if their abilities are to be better understood by parents and educators. ^

The organizational variables which affect the development of interpersonal conflict in a department of nursing: A case study
Milone-Nuzzo, Paula Frances
This study examined the organizational variables which affect the development of interpersonal conflict among faculty members. The setting for this research was a department of nursing in a public university in New England. Utilizing Baldridge's political model of the university as a theoretical framework, organizational variables including goals and values, interest groups, organizational role, participation in decision-making and perceived equitability of treatment were examined. Data were collected through semi-structured interviews with the members of the organization, non-participant observation of selected faculty meetings and document analysis. Trends in the data were identified through content analysis. The emergent category, characteristics of the formal leader, was revealed through inductive analysis of the data.^ The results of this study indicated that the organization itself had little if any interpersonal conflict. Consistent with the organizational literature, the variables commonly associated with minimum interpersonal conflict--knowledge of roles and responsibilities, perceived equitability of treatment and the absence of multiple interest groups--were present in the organization. Conversely, divergent goals and values, interest groups in the areas of clinical specialization and length of time teaching in the department and active participation of the faculty in the decision-making process were found to be present. While such variables have traditionally promoted interpersonal conflict, this was not the case in this particular environment.^ Characteristics of the formal leader was identified by the faculty as a significant variable in the amount of interpersonal conflict in the department. Two sub-categories--administrative style and willingness to negotiate--were suggested by the data as being related to little interpersonal conflict among the faculty. The democratic leadership style of the director, coupled with her willingness to negotiate with the faculty on important issues, significantly affected the organizational environment and fostered positive working relationships among the faculty.^ It is hypothesized that the unique nature of this organization, coupled with the participatory role of the formal leader, served to minimize conflict. Additional variables not explored in this study, such as personality, gender, and role of the professional in an organization need to be examined in further research. ^

The impact of technology on school health: A national Delphi probe of change to 2005 A.D.
Avery, Maureen Regan
Predictions of changes in the role of the school nurse into the mid-future were gathered through the Delphi technique. A national panel of school nurse consultants and certified school nurses identified technological and social changes which they predicted would alter school health practice. A three round process provided individual forecasts, which were then combined into 47 statements of predicted change. Each expert was asked to indicate predictability and desirability for each occurrence. Consensus was reached in 16 of the items.^ Strongest agreement centered around computerization of health records, younger children within the educational setting requiring supervision of the school nurse; more medically fragile children in school systems; and the expanded role of the school nurse into more health teaching and community health settings. The school nurses predicted greater role expansion and increased use of technology for communication, screening and health maintenance in schools. The consultants were less optimistic in these areas, citing the limitations of finances and adequate professional staffing for such predicted changes. All panelists predicted an increase in professional education and the level of practice essential for school nursing in the future.^ Conclusions drawn from this Delphi study on school nursing include: need for greater funding; the suitability of computerization within school health practice and education; dedication of the school nurses to provide the level of practice required for the changing school population; and the desire of the experts to be recognized as true partners with the educators in preparing students for productive lives. ^

Information processing of complex visuals and its relationship to cognitive style and cerebral dominance
Hebert, Pauline Frances
The problem. The problem examined relationships among (1) cognitive style (at two levels: field dependence, field independence), (2) a variable's location in a visual field (at two levels: right third and left third of a visual scene) and (3) a repeated measure of information processing--object manipulation in a visual field--(at four levels: object addition, object subtraction, object substitution and unaltered scenes) with variables of cerebral dominance, visual complexity and simulated ecological validity held constant. These variables were selected to assess their effects upon subjects' visual recognition abilities.^ Experimental design. A 2 x 2 x 4 factorial design was employed with dependent variable data--visual recognition scores--analyzed by a repeated measures ANOVA.^ Experimental procedure. A research sample of baccalaureate nursing students were administered the Group Embedded Figures Test (GEFT) to assess cognitive style grouping and Levy's criteria was employed to identify cerebral hemispheric dominance. Subjects who tested as right hemisphere dominant were omitted from the study, leaving a homogeneous population of left hemisphere dominant subjects.^ Subjects viewed 25 2" x 2" projected colored and simulated but ecologically valid visual scenes, followed by a recognition test of 150 scenes, one-half of which were unaltered scenes, while the second half contained altered scenes. Scenes were altered by object addition (25), object subtraction (25), and object substitution (25). Subjects were randomly assigned to one of two treatment groups, with object manipulations occurring either in the right or left third of the visual field. Subjects with complete sets of data were blocked into field dependent groups (N = 87) and field independent groups (N = 90), according to GEFT scores.^ Summary of findings. One significant main effect was obtained on object manipulations (F = 15.97; df = 3/519; p $<$.001). Correlated t-tests established a significant difference on five of the six different object manipulation comparisons. No significant first order interactions were identified. A second-order interaction showed significance of effect for cognitive style interacting with object location under conditions of object subtraction (F = 7.75; df = 1/173; p =$<$.00). ^

Iraqi Arabic morphophonemics
Majdi, Basim Badi
This thesis gives an account of the alternations that occur in the root forms (in particular, in the triconsonantal verbal root) of Iraqi Arabic (IA) words as a result of morphological affixation (e.g. in the perfective and imperfective paradigm of verbs, nominative and accusative paradigms of nouns and in prepositional cliticization). The phonological alternations studied include vowel deletion, insertion, and lengthening, as well as consonant gemination and glide vocalization.^ In this thesis, the theoretical framework is that of generative phonology. Following Chomsky and Halle (1968), I assume that related words have identical segmental lexical representations down to affixes, and these representations are related to phonetic representations by rules of phonology. The segmental representations are given a hierarchical syllable structure analysis (Kahn(1976), Selkirk (1980, 1982)). These hierarchical structures are interpreted as X-bar type projections of vowels (Hong and Michaels (1985), Michaels (1985), Majdi and Michaels (1987)). That is, V$\sp0$ (the syllable head) projects a category V$\sp\prime$ (the rhyme) which optionally licenses a C-position (Coda), and V$\sp\prime$ projects a category V$\sp{\prime\prime}$ (the syllable) which obligatorily licenses a C-position (Onset). Each position licensed at the X$\sp0$ level can contain no more than one segment. The rules which relate underlying and surface syllable structure representations are restricted to context-free operations in line with current work in syntax (Chomsky (1981), Lasnik and Saito (1984)) and are constrained by locality conditions and the requirements of syllable structure preservation.^ In this thesis, the above mentioned phonological alternations are investigated as automatic consequences of the interaction of syllable structure and stress assignment. As in other Semitic languages, consonantal roots must be preserved in IA. Fitting these consonantal roots into possible syllables requires the creation of syllable heads (vowel insertion) to license stranded consonants or the removal of syllable heads (vowel deletion) which are themselves stranded. Vowel lengthening and consonant gemination are investigated.^ The analysis also provides an account for the quality of affixation which affects the perfective and imperfective paradigms. The thesis argues that the two are formed by one affix system with an alternative realization in prefix and suffix forms. (Abstract shortened with permission of author.) ^

Transient and isotopic tracing kinetic study on supported rhodium catalysts in the CO hydrogenation reaction
Efstathiou, Angelos Michael
Methanation and hydrocarbon synthesis from CO and H$\sb2$ was studied using 5.2 wt% Rh/Al$\sb2$O$\sb3$ and 2.5 wt% Rh/MgO catalysts at 1 atm total pressure. Transient responses to the switches between various feed mixtures, including $\sp{13}$C labeled feeds, to a gradientless microreactor were used to obtain the in-situ surface composition of the catalysts.^ On Rh/Al$\sb2$O$\sb3$ in the temperature range of 180-260$\sp\circ$C the coverage of surface CO varies between 0.98 and 0.6 of a monolayer. This surface CO can be all exchanged off the surface by $\sp{13}$CO. The methanation reaction passes through a small reservoir of a very active carbon species CH$\sb{\rm x}$, between 0.03 and 0.08 of a monolayer. Large amounts of inactive carbon and formate species, between one and two monolayers were found. The formate and part of the inactive carbon species must be located on the alumina support. These two species do not participate in the mechanistic carbon pathway from CO to form methane, where the dissociation of CO must be considered as the rate determining step.^ On RH/MgO, it was found that the methane turnover frequency is an order of magnitude less than that when Rh/Al$\sb2$O$\sb3$ is used. Characterization of the catalyst before and during the kinetic study revealed drastic changes in the amount of H$\sb2$ and CO chemisorption and a large loss in its initial activity. The CO temperature programmed desorption study showed also a drastic change between the spectrum obtained from the catalyst before and after exposure to synthesis gas. The temperature programmed desorption and the CO temperature programmed reaction study for the two catalysts suggests that the binding energy of CO on Rh/MgO is higher than on Rh/Al$\sb2$O$\sb3$. Between 260$\sp\circ$C and 300$\sp\circ$C, the surface coverage of CO on Rh/MgO is about one monolayer, and that of active carbon species CH$\sb{\rm x}$ less than 0.02 of a monolayer. Therefore, as for the Rh/Al$\sb2$O$\sb3$, the rate of dissociation of surface CO largely controls the overall methanation rate. When the Rh/MgO catalyst reaches a reproducible activity, negligible amounts of inactive carbon are found. Formate may be present on the magnesia support, but is not reactive towards hydrogen and does not participate in the sequence of steps to produce methane. ^

Differences in information processing characteristics between gifted achievers and gifted underachievers
Lehmann, Franciene Alexa
School psychologists are frequently called upon to identify gifted students. There is perhaps a no more educationally difficult situation than one that requires intervention recommendations for a gifted underachiever. Current research and priority on identifying the discrepancy between potential and achievement of all students indicates a need to assess the information processing skills of gifted underachievers is paramount. Clear relationships are apparent between the means by which children process information and their achievement. In order to establish discrepancy criteria it is first necessary to examine differences between the information processing skills of gifted achievers versus gifted underachievers.^ The purpose of this study was to identify the role that information processing deficits play in academic underachievement of gifted students, and lend these deficits consideration in identification of and intervention with gifted underachieving students.^ The Bloomer Learning Test, a measure which evaluates information processing ability, was administered to 60 gifted achievers, and 74 gifted underachievers in a suburb of Toronto, Ontario. Analysis of Variance and Discriminant Function Analysis Procedures were employed to determine significant differences in performance between the groups, and the ability of subtest performance or combinations of subtest performance to explain group membership.^ Although sample selection was limited to a school system which has a procedure for identifying gifted underachievers this study is considered significant because of the information gained concerning the difference in information processing skills between gifted achievers and gifted underachievers. ^

The politics of maneuverability: Chinese-Soviet conflict and North Korea
Youn, Hai-Su
The purpose of this research was to ascertain how North Korea was able to maneuver itself successfully between China and the Soviet Union. Analysis of the tripartite relationship was based on the following theoretical background of great power-small power relations. When two great powers are in confrontation, each increases its pressure upon a small power in order to keep it within its sphere of influence. Under such circumstances, the small power can exercise only a small degree of maneuverability between the two great powers. As the relations between the great powers improve, however, both powers diminish their pressure upon the small power and begin to cooperate with it in order to maintain the status quo rather than trying to contain it within their sphere of influence. The small power can then expand its freedom of action with weaker pressure from the great powers. Through this process, the small power increases its maneuverability.^ This research tested the hypothesis that the lesser the intensity of the Sino-Soviet conflict, the greater North Korea's maneuverability between the two great powers by comparing three successive periods (1978-81, 1982-84, and 1985-87) that were characterized by the changes in tenor of Sino-Soviet relations.^ The results of this research can be summarized as the following. During the first period of Sino-Soviet conflict, both great powers simultaneously increased pressure on North Korea to bring it into its sphere of influence because North Korea carried a critical geopolitical importance to them. Under these circumstances, North Korea attempted to extract as much support as they could from both great powers by maintaining a balance between them. However, its efforts were constrained by the tension existing between the two great powers. As a result, North Korea's maneuverability during this period was limited. However, as Sino-Soviet relations improved from the beginning of the second period, their pressure on North Korea decreased. Therefore, North Korea could be more assertive in seeking support from the two great powers. As a result, its maneuverability was increased greater amount of political and economic supports from both great as it continued to receive an increasingly greater amount of political and economic support in the second and third period. ^
