This study investigates the impact of sociocultural mediators in relation to eating disorders among male undergraduates. Literature on eating disorders has demonstrated that a thin body shape ideal depicted in the media directly contributes to eating pathology among females, but little research has investigated the direct effects of ideal body shape images among men. The focus of the present investigation was to assess the direct effects of exposure to the ideal male body shape on men’s affect, self esteem, body satisfaction, and endorsement of U. S. societal ideals of attractiveness. In addition, the relation of these variables to bulimic symptomatology was examined. Modeling a study conducted on women (Stice & Shaw, 1994), male undergraduates between the ages of 18 to 25 participated in premeasure (N = 169) and post measure (N = 95) conditions. Participants in the post measure were randomly exposed to pictures from magazines containing either male models depicting the ideal body shape, an average body or pictures of clothing without models. Results from repeated mulitvariate analysis indicated that exposure to the ideal body shape condition did not demonstrate significant negative changes in men’s affect, self esteem, body satisfaction or endorsement of U. S. societal ideals of attractiveness. …

This study described the mentoring relationship between doctoral nursing students and their committee chairs. Twenty-two public university doctoral programs responded to a request for names and addresses of their doctoral candidates. The Major Professor Mentoring Scale was used to measure the mentoring relationship. The survey also included demographic and open-ended questions regarding the student-committee chair relationship. Surveys were mailed to 269 doctoral students with an 86% return rate. A principal components analysis was performed to identify the structure underpinning the relationship. The typical doctoral student in this sample was found to be a 44 year old Caucasian female, married with children, working full or part time while pursuing a PhD degree. Students traveled an average of 85 miles each way to campus and nearly half had selected their program based on its location. The typical committee chair was a Caucasian, tenured, associate or full professor between 46 and 69 years of age. The majority of chairs were married and had funded research projects. The students in the study reported knowing their chairs for an average of five years. The study revealed that mentoring is occurring in the majority of relationships between doctoral nursing students and their committee chairs. Students identified …

The relationship between occupational stress and burnout was investigated through a meta-analysis of 81 studies and 364 correlations. Occupational stress was measured by role conflict, role ambiguity, workload, cumulative role stress, job specific stress/stressors, and work setting characteristics. Burnout was measured by the Maslach Burnout Inventory, 1981 and 1986 versions, emotional exhaustion, depersonalization, and reduced personal accomplishment components of burnout, measures of tedium, and the Staff Burnout Scale for Health Professionals. Thirty occupations in human and non-human service organizations throughout four publication periods were examined. Results indicated occupational stress strongly predicts burnout in non-human service organizations like industry and manufacturing as well as the human services. Job specific stressors most strongly predict burnout across organization types and occupation. Occupational stress predicts emotional exhaustion and depersonalization more than perceptions of reduced personal accomplishment. The findings support the use of transactional models of stress which consider occupational context as a precipitator of burnout, especially emotional exhaustion.

The intent of this dissertation is to investigate Michael Tippett's eclectic approach to the sonata form in the twentieth century as demonstrated in his Sonata No. 1. Topics of discussion include historical background of English music, particularly the English piano sonata, at the turn of the century (chapter 1), biographical information and a general overview of Tippett's music (chapter 2), a brief examination of Tippett's Sonata Nos. 2, 3, and 4 (chapter 3) and a formal analysis of Sonata No. 1 as well as Tippett's approach to contrapuntal techniques, rhythm, harmony and tonality (chapter 4). In addition to the lecture recital given on February 1, 1999, three others were given: the first recital, on April 3, 1995, contained works by Beethoven, J.S. Bach/Busoni, and Bartok: the second recital, on February 5, 1996, included works by Schumann, Mozart, and Ginastera: and the third recital, on January 2, 1998, featured works by Barber and Chopin.

This study involves the investigation of the basis and validity of considering health information as therapeutic, the definition of Information Therapy, and whether the therapeutic nature of information can be measured empirically. The purpose of the study is to determine if there are any significant differences in the therapeutic effect of Information Therapy through the different delivery modes of support groups communicating face-to-face and those utilizing computer-mediated communication on the Internet. The comparison of these groups revealed no significant differences on three measures of health: physical, mental, and social support. Because one communication medium is not found to be advantageous over the other, the use of the computer can extend the benefits of Information Therapy to the home-bound, to those in remote areas, to people with time restraints, and those who may be shy. The validity of the therapeutic nature of information was verified by participant report of the effect of a health information search. Results demonstrated that the primary source for information is the physician, followed by the Internet, and 77% of participants reported a positive or therapeutic effect when health information was found. These results are significant because individuals who are in positions to deliver Information Therapy can …

Managing the movement of components and products from suppliers to customers and ultimately to end-users is undergoing rapid changes. Supply chain management has increasingly gained attention as companies have sought to reduce costs and improve service performance in a quest for gaining an advantage on the competition.

Night of no Exile is a collection of poems preceded by a critical article entitled "‘Exile seems both a blessing and a curse': A Blissful Reading of Li-Young Lee's Poetry." That article discusses Lee's quest to achieve communication, truth, and transcendence through poetic language and concludes that he finally reaches his goal through a leap from narrative poetry to lyricism. The "exile" alluded to in the title of the article is not only geographic, but also interioran exile due to the natural limitations of all languages, and which can be bridged only in linguistic ways. Lee's solution to that problem (lyricism) turns his poetry into what Roland Barthes would call "a text of bliss," a text that manages to deeply destabilize language, while simultaneously achieving a new kind of meaning. In the main body of the manuscript, the first section contains short love lyrics. The second section, "Night of no Exile," is an attempt at the demanding genre of the longer lyric poem. The third section uses short lyrics to explore various topics, such as discovering one's identity, friendship and solidarity between women, family history, and childhood memories. Finally, the last section includes poems, four of them longer, attempting to …

The glyoxalase system mediates the conversion of methylglyoxal, a toxic ketoaldehyde, to D-lactic acid. The system is composed of two enzymes, glyoxalase I (Glo-I) and glyoxalase II (Glo-II), and exhibits an absolute requirement for a catalytic quantity of glutathione (GSH). Glo-I catalyzes the isomerization of a hemithioacetal, formed non-enzymatically from methylglyoxal and GSH, to the corresponding a -D-hydroxyacid thioester, s-D-lactoylglutathione (SLG). Glo-II catalyzes the irreversible breakdown of SLG to D-lactate and GSH. We have observed that ATP or GTP significantly inhibits the Glo-II activity of tissue homogenates from various sources. We have developed a rapid, one step chromatography procedure to purify Glo-II such that the purified enzyme remains "sensitive" to inhibition by ATP or GTP (Glo-II-s). Studies indicate that inhibition of Glo-II-s by nucleotides is restricted to ATP, GTP, ADP, and GDP, with ATP appearing most effective. Kinetics studies have shown that ATP acts as a partial non-competitive inhibitor of Glo-II-s activity, and further suggest that two kinetically distinguishable forms of the enzyme exist. The sensitivity of pure Glo-II-s to nucleotide inhibition is slowly lost on storage even at -80° C. This loss is accelerated at higher temperatures or in the presence of ATP. Kinetics studies on the resultant "insensitive" …

The dissertation uses a number of mathematical formula including de Rham cohomology with complex coefficients to state and prove extension of Brieskorn's Lemma theorem.

This study examined the way in which the top 100 "most wired" colleges and universities provide online student services. Named by a national publication in May 1998, these colleges and universities were chosen because of their technological infrastructure, courses offered online, public computers on campus, and online student services, among other aspects.

Utilization of World Wide Web style Web-Based Intranet Systems (W-BIS) is a rapidly expanding information delivery technique in many organizations. Published reports concerning these systems have cited return on investment values exceeding 1300% and direct payback time periods as low as six to twelve weeks. While these systems have been widely implemented, little theoretically grounded research has been conducted in relation to users' acceptance, utilization or the perceived quality of these systems. The study employed a two-site investigation of corporate Web-Based Intranet Systems, with surveys distributed via the traditional mail system. The complete survey instrument distributed to employees included the ServQual/ServPerf, User Information Satisfaction, Ease of Use/Usefulness, and Computer Playfulness instruments. In addition to these previously developed instruments, the survey instrument for this study included measures of Web-Based Intranet Systems utilization and usefulness along with respondent demographics and subordinate-reported managerial commitment. This study investigated the reliability and validity of the ServQual/ServPerf instrument in an information systems service environment. The same analysis was conducted of the more generally accepted User Information Satisfaction instrument.

Within the last decade, more organizations are utilizing a non-traditional workforce. Specifically, these organizations are utilizing contract workers as resources to provide services and manufacture products. While this change in workforce provides benefits to organizations, the change also presents numerous challenges such as turnover. The turnover involved in such a relationship along with the addition of newcomers translates into an organizational socialization and knowledge transfer (KT) issue, because contract workers as well as employees need to be efficiently brought into a new organization, and knowledge needs to be shared with these new individuals so that they can effectively contribute to the work process. It is contended that organizations follow a typical, informal organizational socialization "policy" which involves KT in getting new contract workers and employees up to speed. This study addressed the typical organizational socialization policy as it is represented by formal knowledge transfer (FKT) via instructor-led/classroom training (ILT) and computer-based training (CBT) and by informal knowledge transfer (IKT) via a social network. The study focused on IKT, because companies understand this type of KT the least. In order to evaluate the organizational socialization of contract workers for this study, the contract worker population was compared to a baseline population …

Paul Wittgenstein (1887-1961) made significant contributions to the piano literature for the left hand through numerous commissioned works as well as his own transcriptions. In the transcriptions, Wittgenstein preserved the texture of two-hand music, aiming for the simulation of the original works. This requires special techniques in the performance by the left hand alone. This dissertation investigations technical means and performance problems associated with the transcriptions as well as Wittgenstein's own recordings of selections from his works. Chapter 1 serves as an introduction, providing a historical overview of the role of the left hand in two-hand piano literature. Chapter 2 gives biological information on Paul Wittgenstein and discusses the commissioned works. Chapter 3 investigates special techniques in the transcriptions, in the areas of arpeggios, widespread chords, fingering, pedaling, and others. Chapter 4 discusses Wittgensteins's performance style based on his recordings. Chapter 5 presents a conclusion pointing to the benefits of performing left-hand music in two-hand piano playing.

The primary purpose of this study was to use some of the action methods of playback theatre to facilitate the acquisition of knowledge through the experience of building community. The impact of action methods on group dynamics and the relationship among methods, individual perceptions, and the acquisition of knowledge were analyzed. The researcher suggested that playback theatre action methods provided a climate in which groups can improve the quality of their interactions. The Hill Interaction Matrix (HIM) formed the basis for the study's analysis of interactions. Since the researcher concluded there were significantly more interactions coded in the "power quadrant" after training, the researcher assumed that playback theatre action methods are a catalyst for keeping the focus on persons in the group, encouraging risk-taking behaviors, and producing constructive feedback between members. Based on session summaries, individual interviews, and an analysis of the Group Environment Scale (GES), the training group became more cohesive, became more expressive, promoted independence, encouraged self-discovery, and adapted in innovative ways. The experience of an interconnected community created a space where positive growth could occur. The researcher concluded that the process of community building is intricately connected with a person's ability to make meaning out of experiences. …

Theoretically grounded and empirically testable conceptualizations that offer alternative explanations regarding sales force performance and turnover can: (a) enhance understanding regarding these pivotal outcomes, and (b) augment an organization's capability to increase sales and decrease turnover. The study advances one such explanation by conceptualizing and testing a perceptual model that links a salesperson's psychological climate dimensions to organizational commitment, performance, and turnover. The framework the study proposes respecifies the leadership and work group dimensions of psychological climate into four distinct perceptions (i.e., a salesperson's perceptions regarding the behaviors of work group, sales manager, senior management, and non sales employees in the organization). These climate dimensions are posited to influence positively a salesperson's organizational commitment which consequently influences positively the salesperson's effort and intention to stay with the organization. The proposed outcomes of organizational commitment result in increased performance and decreased turnover. Success beliefs and perceived behavioral control are posited to moderate the relationship between the salesperson's organizational commitment and effort. The study tests the hypothesized relationships on a sample of salespersons belonging to a telecommunications organization utilizing path and hierarchical regression analyses.

This study addresses on facet of Joseph Turrin's compositional oeuvre: his published works for solo trumpet. Complete histories if all six trumpet compositions are chronicles. A discussion of formal organization and significant style features including harmonic language, melodic style and rhythmic features is included. A detailed performance analysis follows. The degree of difficulty of each work is assessed through an investigation of tessitura, range, melodic contour, endurance factors, fingerings, and technical features of the accompaniment. Analysis of tempi and dynamics, articulation and phrasing, and timbral considerations provides additional points of focus to the study. Finally, the importance of Turrin's works for trumpet and his impact on trumpet literature is assessed. Idiomatic aspects of composition that make Turrin's music attractive to performers are investigated and discussed.

A little-known chamber work by Benjamin Britten is the dramatic cantata Phaedra, op.93, for mezzo-soprano and small orchestra. Among his chamber works, the solo cantata was a musical form used only once by Britten, thus making Phaedra unique among Britten's oeuvre. Britten chose a genre that flourished in the seventeenth and eighteenth centuries the cantata - as a vehicle for the story of Phaedra. He employs clear allusions to Baroque music in Phaedra by the use of harpsichord and continuo in the recitatives, ornamentation, and word painting. The text for Britten's setting of Phaedra is a translation of Jean Racine's Phedre by the American poet Robert Lowell. From Lowell's complete play, Britten extracted Phaedra's key speeches that deal with her three confessions of incestuous love for her stepson, Hippolytus. These monologues are set in a series of recitatives and arias that make up the entirety of this chamber cantata. In order to gain complete understanding of Phaedra, this document will begin with an investigation into the historical background of Racine's Phedre and the conventions of French tragedy from which it arose. Lowell's translation method will then be explored in comparison to Racine's play. In turn, Britten's extractions from Lowell's translation …

This exploratory research focused on a problem stated years ago by Vannevar Bush: "The problem is how creative men think, and what can be done to help them think." The study explored the scholarly work process and the use of computer tools to augment thinking. Based on a review of several related literatures, a framework of 7 major categories and 28 subcategories of scholarly thinking was proposed. The literature was used to predict problems scholars have in organizing their information, potential solutions, and specific computer tool features to augment scholarly thinking. Info Select, a personal information manager with most of these features (text and outline processing, sophisticated searching and organizing), was chosen as a potential tool for thinking. The study looked at how six scholars (faculty and doctoral students in social science fields at three universities) organized information using Info Select as a personal documentation system for scholarly work. These multiple case studies involved four in-depth, focused interviews, written evaluations, direct observation, and analysis of computer logs and files collected over a 3- to 6-month period. A content analysis of interviews and journals supported the proposed AfFORD-W taxonomy: Scholarly work activities consisted of Adding, Filing, Finding, Organizing, Reminding, and Displaying …

This study was designed to investigate the correlation of the variables of gender, Myers-Briggs Type Indicator (MBTI) personality preferences, and androgyny as measured by the Bem Sex Role Inventory (BSRI) in Counselor Education graduate students. Instruments were administered to Counselor Education graduate students at nine institutions in five national regions. A total of 172 participants (18 males and 154 females) who were enrolled in Master's level theories courses or practicum courses completed a student information sheet, informed consent, MBTI, and BSRI. Instruments were hand scored and chi-square test was used to determine significance of the hypotheses; the saturated model of log linear analysis was the statistic used for the research question. As predicted, of the sixteen MBTI types, the most common for Counselor Education graduate students emerged as ENFP: extraversion, intuition, feeling, and perception. Additionally, this MBTI type was found to be significantly more common among the population of Counselor Education graduate students than is found among the general population. The expectation that more male Counselor Education graduate students would score higher on the androgyny scale of the BSRI was unsupported; low sample size for male Counselor Education graduate students prevented use of chi-square; however, it was apparent through the …

Generally, nonlinear optics studies investigate optically-induced changes in refraction or absorption, and their application to spectroscopy or device fabrication. The photorefractive effect is a nonlinear optical effect that occurs in solids, where transport of an optically-induced free-carrier population results in an internal space-charge field, which produces an index change via the linear electrooptic effect. The photorefractive effect has been widely studied for a variety of materials and device applications, mainly because it allows large index changes to be generated with laser beams having only a few milliwatts of average power.Compound semiconductors are important photorefractive materials because they offer a near-infrared optical response, and because their carrier transport properties allow the index change to be generated quickly and efficiently. While many researchers have attempted to measure the fundamental temporal dynamics of the photorefractive effect in semiconductors using continuous-wave, nanosecond- and picosecond-pulsed laser beams, these investigations have been unsuccessful. However, studies with this goal are of clear relevance because they provide information about the fundamental physical processes that produce this effect, as well as the material's speed and efficiency limitations for device applications.In this dissertation, for the first time, we time-resolve the temporal dynamics of the photorefractive nonlinearities in two zincblende semiconductors, …

Previous research has examined factors that predispose collegiate football players to injury (e.g., Petrie, 1993a, 1993b) as well as factors that influence athletes' psychological adjustment to being injured (e.g., Brewer, 1993; Leddy, Lambert, & Ogles, 1994). Despite the reports of the NCAA Injury Surveillance System that the greatest number of football injuries occur during the spring preseason (NCAA, 1997), studies have only examined injury during the regular season. Thus, the purpose of this study was to investigate the antecedents and consequences of injury in collegiate football players during the spring preseason and across the regular competitive season. Specifically, life stress, social support, competitive trait anxiety, athletic identity, coping style, and preinjury mood state was measured to determine their relationship with the occurrence of injury and with postinjury emotional responses in athletes who sustain an injury at some point during either the spring preseason or regular competitive football season. The overall incidence of athletic injuries was low and the athletes suffered more severe injuries than has been typically found in collegiate football samples. Negative life stress was found to be directly related to the occurrence of injury and to postinjury negative emotional response and was moderated by other psychosocial variables in …

This study attempts to explore the perceived value of Problem-Based Learning (PBL) in training teachers of students with behavioral disorders (E/BD) in Hong Kong. It represents an effort to improve the predominately lecture focussed approach adopted in many preparation programs. Data on the training needs of Hong Kong teachers were also acquired and 31 knowledge/skills areas related to teaching students with E/BD were identified. Subjects viewed the PBL approach as dynamic, interesting and incentive driven. It develops skills involved in group learning, self-directed learning, use of information resources and problem-solving. Most important, teachers felt they were supported to explore the practical problems they personally encountered in the classroom and actions they could take to resolve them. Difficulties in using PBL included a lack of resources and the tendencies of most Chinese students to accept rather than challenge others' ideas.

The potential for human exposure to pesticides exists particularly for agricultural workers (i.e. migrant workers) and individuals within close proximity to pesticide-sprayed crops (i.e. those living on or near agricultural farms). Children, through biology and behavior, may be more susceptible and vulnerable to exposure to pesticides than adults. The purpose of this study was to examine young populations particularly at-risk for occupational or accidental exposure to pesticides and determine associated behavioral, emotional, and physical symptoms. A total of 444 students from two South Texas school districts completed questionnaires assessing level of risk of exposure to pesticides and were categorized into at-risk and low risk categories. Physical, emotional, and behavioral symptoms were obtained using the Youth Self-Report. Children who were at-risk demonstrated significantly higher scores on the Youth Self-Report (YSR) in the areas of anxious/depressed, attention problems, social problems, somatic complaints, thought problems, withdrawal, internalizing behaviors, and total problem behaviors than children who were at lower risk of pesticide exposure. Odds ratios were obtained and suggested that children in the at-risk category were more five times more likely to score in the clinically significant range on the Attention Problems subscale, and three times more likely to score in the clinically significant …

This dissertation is a cross-national, empirical study of human rights conditions in a dynamic international political economy. The scope of the examination covers 176 developed and developing countries from 1980 through 1993. Through evaluating the numerous theoretical aspects of human rights conceptualization, I draw upon Shue's framework and consider whether there are indeed "basic rights" and which rights should fit into this category. Further, I address the debate between those who claim that these rights are truly universal (applying to all nations and individuals) and those who argue that the validity of a moral right is relative to indigenous cultures. In a similar vein, I empirically investigate whether various human rights are interdependent and indivisible, as some scholars argue, or whether there are inherent trade-offs between various rights provisions. In going beyond the fixation on a single aspect of human rights, I broadly investigate subsistence rights, security rights and political and economic freedom. While these have previously been addressed separately, there are virtually no studies that consider them together and the subsequent linkages between them. Ultimately, a pooled time-series cross-section model is developed that moves beyond the traditional concentration on security rights (also know as integrity of the person rights) …
