Synthesis of the Personal and the Political in the Works of May Stevens
This thesis is an investigation of the way in which the painter May Stevens (b. 1924) synthesizes her personal experiences and political philosophy to form complex and enduring works of art. Primary data was accumulated through an extended interview with May Stevens and by examining her works on exhibit in New York and Boston. An analysis of selected works from her "Big Daddy" and "Ordinary/Extraordinary" series revealed how her personal feelings about her own family became entwined with larger political issues. As an important member of the feminist art movement that evolved during the 1970s, she celebrated this new kinship among women in paintings that also explored the contradictions in their lives. In more recent work she has explored complex social issues such as teenage prostitution, sexism, and child abuse in a variety of artistic styles and media. This study investigates how May Stevens continues to portray issues of international significance in works that consistently engage the viewer on a personal, almost visceral level.

Biodiversity of Dragonflies and Damselflies (Odonata) of the South-Central Nearctic and Adjacent Neotropical Biotic Provinces
The south-central United States serves as an important biogeographical link and dispersal corridor between Nearctic and Neotropical elements of western hemisphere odonate faunas. Its species are reasonably well known because of substantial collections, but there has been no concerted effort to document the extent of biodiversity and possible geographic affinities of dragonflies and damselflies of this region. The recent discoveries of Argia leonorae Garrison, Gomphus gonzalezi Dunkle and Erpetogomphus heterodon Garrison from southern and western Texas and northern Mexico suggest that Odonata species remain to be discovered in this area, particularly from far south Texas and northern Mexico. I have documented a total of 12,515 records of Odonata found in 408 counties within the south-central U.S. A total of 73 species of damselflies and 160 species of dragonflies was revealed in the region. The 233 (197 in Texas) Odonata species are distributed among 10 families and 66 genera. Illustrated family, generic, and species-level keys are provided. Since the beginning of this work in the Fall of 1993, one species has been added each to the Louisiana and Oklahoma faunas, and 12 species have been added, previously unreported from Texas, including four new to the U.S. The area of highest Odonata …

The Effect of Presence of Support Systems and Level of Agreement on the Performance of Work Groups
In the study of team-based organizations most of the research has focus on the internal make-up and structure of teams. Recently there has been more interest in the effects that environment has on teams. With this new focus Support Systems in organizations have become an area of interest. Examining the perceptions of workers with respect to support systems of organizations could give insight into performance. This study specifically examines the interaction between a team's shared perception of the support in their environment and the level of support in their environment. The interaction between the two does seem to have a strong relationship with perceived performance. How do the two concepts interact, and what does this mean for organizational designers? Both questions are discussed.

Effect of Task Appropriateness, Social Comparison, and Feedback on Female Goals, Performance, and Self-Confidence with a Motor Task
Lenney (1977) concluded that achievement gender differences were predicted by females' lower self confidence and expectancies in competitive situations, identifying three variables that mediated female self confidence in achievement situations, (1) task appropriateness. (2) social comparison, and (3) feedback. The present study manipulated all three mediating variables with 240 undergraduate 18-25 year old female subjects with the pursuit rotor task that requires tracking a moving (40 rpm's) white light with a hand-held stylus for 60 seconds. Response measurement was based upon time on target. Subjects were tested over five trials while setting goals for each trial. Females were randomly assigned to a male appropriate, female appropriate, or gender neutral task condition, a competition or alone condition, and to one of four feedback conditions (no feedback, feedback about own performance only, feedback about own performance that provided the perception that subject was performing better than an opponent and/or average on each trial, or feedback about own performance that provided the perception that subject was performing poorer than an opponent and/or average on each of the five trials). Results from the 2 (social comparison) X 3 (task appropriateness) X 4 (feedback) ANOVA were contradictory to previous findings (Corbin, 1981; Petruzzello & Corbin, …

Nesting Ecology and Reproductive Correlates in the Desert-nesting Gray Gull Larus Modestus
General objectives of my study were to describe the reproductive ecology of gray gulls in the large Lealtad colony, with emphasis on demographic parameters and physiological adaptations of eggs and chicks, which would complete some original objectives established in the early 1980's by Guerra and Fitzpatrick. Specifically, my study focused on describing, then comparing with other desert and non-desert nesting larids, interactive effects of ambient physical conditions and nest-site predation on eggs and chicks.

"Beowulf": Myth as a Structural and Thematic Key
Very little of the huge corpus of Beowulf criticism has been directed at discovering the function and meaning of myth in the poem. Scholars have noted many mythological elements, but there has never been a satisfactory explanation of the poet's use of this material. A close analysis of Beowulf reveals that myth does, in fact, inform its structure, plot, characters and even imagery. More significant than the poet's use of myth, however, is the way he interlaces the historical and Christian elements with the mythological story to reflect his understanding of the cyclic nature of human existence. The examination in Chapter II of the religious component in eighth-century Anglo-Saxon culture demonstrates that the traditional Germanic religion or mythology was still very much alive. Thus the Beowulf poet was certainly aware of pre-Christian beliefs. Furthermore, he seems to have perceived basic similarities between the old and new religions, and this understanding is reflected in the poem. Chapter III discusses the way in which the characterization of the monsters is enriched by their mythological connotations. Chapter IV demonstrates that the poet also imbued the hero Beowulf with mythological significance. The discussion in Chapter V of themes and type-scenes reveals the origins of …

Perceptions of Managers in Kuwait on the Role of the Multinational Corporations in Change in Kuwait
The purpose of this study is to investigate the perceptions of managers in Kuwait (both Kuwaiti and non- Kuwaiti) on the effects of multinational corporations (MNCs) in Kuwait and whether these effects were beneficial. The problem motivating this study is the effects that MNCs have on the social, cultural, political, legal, economic, business, and technological environments of their host countries, especially in developing nations. This study is based on a survey of the perceptions of 1,344 managers in Kuwait on the role of MNCs in changes in Kuwait. A review of the literature on MNCs and their relationships with their host countries is provided. This review focuses on four major environmental dimensions (Social-Cultural, Political-Legal, Business-Economic, and Technological) that are affected by MNCs. The factor analysis performed for this study supports this classification of the dimensions in the environment. An English questionnaire was developed from the list of major items in each of these dimensions. An Arabic version was developed using a "double-translation method." Both the English and Arabic versions of the questionnaire were pilot tested. The instrument proved to be reliable and valid. The study utilizes a 2 x 3 block design, categorizing subjects by nationality (Kuwaiti, other Arab, others) …

A Structural Equation Analysis of Intergenerational Differences in Attitudes toward Individual Modernity in the United Arab Emirates: Implications for Cross-Cultural Research
It has been widely believed that modernity is a byproduct of a nuclear family system, a highly urbanized society, and a secular way of life. As such, developing countries are characterized as modern insofar as their social and cultural structures are able to correspond to these criteria. To examine the validity of these propositions, data on two randomly-selected generations--daughters and mothers in the United Arab Emirates--were generated.

Organizational Commitment: A Cross-National Comparison of Arab and Non-Arab Employees in Saudi Petrochemical Companies
Individuals with different personal demographics and job-based factors have different attitudes and behaviors, which can influence their levels of commitment to their organizations. These differences in organizational commitment increase as their cultural backgrounds differ significantly. Personal demographics and job-related factors are reliable predictors of employees' commitment to their employing organizations. The purpose of this study was to empirically investigate if there is a difference in the level of employees' commitment to Saudi petrochemical companies on the basis of differences in their personal demographics and job-related factors.

Subsidy ("Vanity") Publishing Among American College and University Faculty
The problem of this study was subsidy ("vanity") publishing among college and university faculty. The purpose of the study was to estimate the extent to which postsecondary faculty use subsidy presses for the publication of their scholarly writings and the professional reasons for which academicians choose these presses to publish their works, viz., tenure, promotion, or salary increase. An additional purpose was to compare the subsidy publication experiences of faculty according to the types of institutions which employ them. The study involved 11 national subsidy publishers and 1,124 subsidy-published authors throughout the United States. Subsidy-published authors were identified occupationally as faculty by their appearance in the 1990 edition of The National Faculty Directory. The subjects in this study consisted of (a) faculty members listed in The National Faculty Directory. 1990 who are (b) known to have used subsidy presses for publishing their writings. A major finding of the study was that the proportion of vanity-published authors who are college and university faculty was small. Twenty-seven percent of the faculty whose books had been published by subsidy presses indicated that they had written and published in order to earn salary increases. Another 23% indicated that they had their books published to …

Teacher Implementation of a Pretreatment Assessment Procedure in a Public Middle School
In an attempt to determine the effectiveness of a pretreatment assessment procedure known as the scatter plot (Touchette, MacDonald, & Langer, 1985), direct observational data was collected by 13 middle school teachers on four "problem" students. After four weeks of data collection, interobserver agreement probes were calculated and a visual analysis of the plotted data was performed to ascertain a possible pattern of problem behavior. Additionally, in an attempt to assess the teachers' perceptions of the scatter plot, the 13 teachers were asked to complete a questionnaire. Although a visual analysis of the plotted data suggested a possible pattern of problem behavior, interobserver agreement probes failed to achieve a desired overall reliability of 90% or higher. Despite a low IOA, results of the questionnaire administered to the 13 teachers generally supported the use of the scatter plot as a means of assessing student behavior. Possible reasons for failing to attain an IOA of 90% or higher include the total number of students in a class, the number of subjects observed per period, the teacher's location in the classroom, and the subjects ability to recognize if the teacher was "looking." Recommendations are provided regarding future research concerning the scatter plot and …

Distractibility, Impulsivity, and Hyperactivity Measured by the Kaufman Assessment Battery for Children and Personality Inventory for Children
Basic criteria for determination of Attention Deficit Hyperactivity Disorder (ADHD) include hyperactivity, impulsivity, and distractibility. Four scales of the Personality Inventory for Children have been found to be useful in the diagnosis of ADHD. Impulsivity and distractibility can affect scores on the Hand Movements, Number Recall, Word Order, Spatial Memory, Arithmetic, Riddles, and Matrix Analogies subtests of the Kaufman Assessment Battery for Children. Subjects were 100 children, aged six through 13 who were referred for psychological assessment. The purpose of this study was to determine if there was a correlation between scores on the four scales of the PIC and the designated subtest scores on the KABC. Four correlations were significant, but of low magnitude.

A Behavioral Model for Detection of Acute Stress in Bivalves
A behavioral model for acute responses in bivalves, was developed using time series analysis for use in a real-time biomonitoring unit. Stressed bivalves closed their shell and waited for the stressful conditions to pass. Baseline data showed that group behavior of fifteen bivalves was periodic, however, individuals behaved independently. Group behavior did not change over a period of 20 minutes more than 30 percent, however, following toxic exposures the group behavior changed by more than 30 percent within 20 minutes. Behavior was mathematically modeled using autoregression to compare current and past behavior. A logical alarm applied to the behavior model determined when organisms were stressed. The ability to disseminate data collected in real time via the Internet was demonstrated.

A Model for Predicting Bereavement Outcome in Widowhood
The present longitudinal study examined the effects and interactions of several variables thought to affect adjustment to conjugal bereavement. Questionnaires were administered to 147 conjugally bereaved subjects and to 46 persons bereaved of close relatives other than spouse. Independent variables included experienced competence (self-esteem, locus of control, coping self-efficacy, and prior coping strategies), impact of loss (anticipation and preventabillty of loss, centrality of relationship and life change), and perceived resources. All of the independent variables were found to be important predictors of adjustment in conjugal bereavement. However, hypothesized interactions among variables were generally not found. Experimental variables were better predictors of adjustment in conjugal bereavement than were demographic variables. Contrary to prediction, widowed subjects tended to become more lonely and showed increased bereavement adjustment difficulties over a six month period of time. However, post hoc analysis suggested that levels of adjustment do not decline over the long term in widowhood. The present study supports a view of widowhood as a multidimensional event, characterized by seemingly contradictory feelings, experiences, and behaviors.
