Iconoclast in the mirror.

This work explores identity positions of speakers in modern and contemporary poetry with respect to themes of subjectivity, self-awareness, lyricism, heteroglossia, and social contextualization, from perspectives including Bakhtinian, queer, feminist and postructuralist theories, and Peircian semiotics. Tony Hoagland, W.H. Auden, Adrienne Rich, and the poetic prose of Hélène Cixous provide textual examples of an evolving aesthetic in which the poet's self and world comprise multiple dynamic, open relationships supplanting one in which simple correspondences between signifiers and signifieds define selves isolated from the world. Hypertext and polyamory serve as useful analogies to the semantic eros characteristic of such poetry, including the collection of original poems that the critical portion of this thesis introduces.

An Examination of Methodological Rigor and Its Effects on Organizational Development and Change Outcomes

Access: Use of this item is restricted to the UNT Community
Organizational development and change (ODC) is a broad field because change occurs in all organizations, occurs at multiple organizational levels, consists of numerous interventions, and can impact multiple outcomes. Many ODC efforts attempt to examine the effectiveness of their initiatives, yet fail to account for the quality, or rigor of their methods. The purpose of this paper is to examine how methodological rigor and intervention implementation quality impact ODC outcomes. The results indicate that overall methodological rigor is not a significant predictor of organizational change outcomes; however, several individual rigor criteria exhibit predictive power. Implementation quality is a significant predictor of organizational outcomes, but in a negative direction.

Ethics in Technical Communication: Historical Context for the Human Radiation Experiments

Access: Use of this item is restricted to the UNT Community
To illustrate the intersection of ethical language and ethical frameworks within technical communication, this dissertation analyzes the history and documentation of the human radiation experiments of the 1940s through the 1970s. Research propositions included clarifying the link between medical documentation and technical communication by reviewing the literature that links the two disciplines from the ancient period to the present; establishing an appropriate historiography for the human radiation experiments by providing a context of the military, political, medical, and rhetorical milieu of the 1940s to the 1970s; closely examining and analyzing actual human radiation experiment documentation, including proposals, letters, memos, and consent forms, looking for established rhetorical constructions that indicate a document adheres to or diverts from specific ethical frameworks; and suggesting the importance of the human radiation documents for studying ethics in technical communication. Close rhetorical analysis of the documents included with this project reveals consistent patterns of metadiscourse, passive and nominal writing styles, and other rhetorical constructions, including negative language, redundancies, hedges, and intensifiers, that could lead a reader to misunderstand the writer's original ethical purpose. Ultimately this project finds that technical communicators cannot classify language itself as ethical or unethical; the language is simply the framework with which …

Pyrimidine Enzyme Specific Activity at Four Different Phases of Growth in Minimal and Rich Media, and Concomitant Virulence Factors Evaluation in Pseudomonas aeruginosa

Access: Use of this item is restricted to the UNT Community
Pseudomonas aeruginosa is a Gram-negative rod, aerobic, non-fermenting, oxidase positive, pigment producing, and nutritionally versatile bacterium. Infections by P. aeruginosa are the most important cause of morbidity and mortality in immunocompromised patients, given virulence factor production that suppresses antibiotic therapy and promotes persistent infection. This research is the first comprehensive report of the pyrimidine biosynthetic pathway for all phases of growth in minimal and rich media coupled with the evaluation of virulence factor production of P. aeruginosa in comparison to four other bacterial species (Pseudomonas putida, Pseudomonas fluorescens, Burkholderia cepacia, and Escherichia coli wild-type strains). Cellular growth and passing genetic information to the next generation depend on the synthesis of purines and pyrimidines, the precursors of DNA and RNA. The pyrimidine biosynthetic pathway is essential and found in most organisms, with the exception of a few parasites that depend upon the pyrimidine salvage pathway for growth. Both the pyrimidine biosynthetic and salvage enzymes are targets for chemotherapeutic agents. In our laboratory, research on pyrimidine auxotrophic mutants showed the role of the pyrimidine biosynthetic pathway and its intermediates on P. aeruginosa metabolism and impaired virulence factors production. The present research shows that pyrimidine enzymes are active in all phases of growth, …

Organizational development: A comparison of individual and organizational level change.

Access: Use of this item is restricted to the UNT Community
Organizational change and development (OCD) has been studied by researchers to identify the effectiveness of change initiatives. Because of the broad scope of interventions in OCD, these studies have covered a range of areas including multiple interventions and the methodological rigor used by researchers. However, few have looked at organizational versus individual change within an organization, to examine whether individual change is more effective than organizational change. The purpose of this study is to determine if organizational change occurs in a top down or bottom up manner. A meta-analysis was conducted using 238 field experiments. Each study was coded for intervention and organizational outcome and for individual or organizational level variables. Effect sizes were calculated for each study, each level, and each level by intervention and outcome measure. Results indicate that while OCD interventions overall had a moderate effect size, the level of intervention or outcome was not a moderating variable.

Knowledge management in virtual organizations: A study of a best practices knowledge transfer model.

Access: Use of this item is restricted to the UNT Community
Knowledge management is a major concern for organizations today, and in spite of investments in technology, knowledge transfer remains problematic. This study sought to determine whether a relationship exists among participant group demographics (experience), implementation of an integrated knowledge transfer system (best practices model), knowledge transfer barriers, and knowledge transfer project (Web-based training) outcome in a virtual organization. The participant organization was a network of individuals and groups who practice patient advocacy in the research and treatment of cancer. These advocates volunteer in various capacities and are not collocated nor do they report to any single organizational entity. Volunteer participants were randomly assigned to a treatment or control condition. The treatment participants received a training supplement based upon a best practices knowledge transfer model. All participants reviewed a Web-based communications training module scheduled for deployment by the participant organization. Upon completion of the training program, participants were instructed to practice specific techniques from the program. At the end of this period, participants completed an online survey that measured demographics, perceived barriers to the knowledge transfer, and project outcome. Knowledge transfer barriers were defined as knowledge, source, recipient, and organizational context characteristics that inhibit the expected transfer. Project outcome was a …

Distance Education in the Preparation of Special Education Personnel: An Examination of Videoconferencing and Web-based Instruction

Access: Use of this item is restricted to the UNT Community
This study examined the effectiveness of employing videoconferencing and Web-based instruction in the preparation of special education personnel. Due to the acute shortage of special education personnel, it was anticipated that the use of videoconferencing and online instruction would provide a convenient way for students to attend class without having to travel to the actual location of the educational site. Further, it was believed that this initiative would result in higher student enrollment in special education teacher certification programs, consequently leading to an increase of personnel in the field. Moreover, the increase in personnel would enhance the ability of educational institutions to address the dismal academic, social, and behavioral outcomes of students with disabilities. Information for the study was collected from surveys that investigated how students perceived the use of videoconferencing and web-based instruction in the preparation of special education personnel. Ninety-four graduate students responded to the videoconferencing surveys while 88 responded to the Web-based instruction surveys. Six respondents were randomly selected to participate in face-to-face interviews designed to investigate the effectiveness of both approaches. Findings indicated that videoconferencing and Web-based instruction are convenient ways for students to attend class although videoconferencing sites may not be conveniently located to all …

Conspicuous Consumption and American Political Behavior

Access: Use of this item is restricted to the UNT Community
The following premise is based on the ideas of social theorists who have contributed to understanding the importance of image in society. This proposal argues that political participation is susceptible to exploitation in the form of conspicuous consumption as defined by Thorstein Veblen. The analyses that follow will test the degree to which Americans who demonstrate more traditional forms of conspicuous consumption also tend to show more activity in political venues. While the correlation of these two variables is not sufficient to demonstrate cause and effect, it may be significant enough to attract more researchers to this question: are Americans using political involvement to positively influence the way that their social status is perceived by others?

Many Christian writers point to God through their fiction without openly evangelizing. The images their words evoke lift their secular and religious readers' heads, for God is reflected in their use of language, the emotions they describe, and the actions of their characters. The preface and short stories in this collection aim to show that God's presence can be felt even when people are suffering due to human decisions and mistakes. He is with His creations in the midst of their pain to impart hope when they need it most.

The Effects of Motivational and Instructional Self Talk on the Attentional Focus of High School Distance Runners.

Access: Use of this item is restricted to the UNT Community
The purposes of this study were to examine the (a) attentional focus strategies used by high school distance runners, (b) changes in attentional focus across four laps in three 1.6 km runs, and (c) effects of a pre-performance intervention using motivational and instructional self talk on the attentional focus strategies used by and performance of high school distance runners. Participants (N = 42) completed a background and demographic questionnaire, the Cross Country Attentional Focus Inventory (CCAFI), a motivational and instructional statement survey, and the Self-Motivation Inventory. A series of oneway ANOVAs revealed significant differences in the types of attentional strategies used by each group, as well as fluctuations in use of strategies. The experimental group associated more during the each of the 1.6 km trials, whereas the control group dissociated more throughout each trial. A significant group by week interaction was found, with the experimental group maintaining their performance and the control group slowing from week one to week three.

Treatment Effects Related to EEG-Biofeedback for Crack Cocaine Dependency: Changes in Personality and Attentional Variables

Access: Use of this item is restricted to the UNT Community
EEG biofeedback (neurotherapy) has been demonstrated as effective in the treatment of alcoholism, as evidenced by Peniston and Kulkosky's research efforts. These neurotherapy pioneers evaluated the efficacy of alpha-theta brain wave biofeedback as a treatment for chronic alcohol abuse, citing 80% abstinence rates as measured by improvements in psychopathology, serum beta endorphin levels, and long-term alcohol abstinence. Most research with alpha-theta EEG biofeedback has addressed alcohol addiction. Cocaine is now considered to be the most common drug problem of patients entering treatment for drug abuse. To date, only one controlled study has been published that researched alpha-theta neurofeedback in the treatment of "crack" cocaine addiction. The present study was an extension of a 4-year EEG-biofeedback treatment outcome project underway at a faith-based homeless mission in Houston, Texas, with male "crack" cocaine addicts. Changes in personality, attention, and impulsivity were measured following 30 sessions of a non-individualized EEG -biofeedback protocol. Experimental subjects received a variant of the Peniston-Kulkosky alpha-theta protocol for 30 sessions while controls received all elements of the experimental protocol except the EEG biofeedback. Assessment measures included the MMPI-2 and the IVA. Although experimental subjects showed greater mean improvement on most MMPI basic scales and all IVA Attention related …

Synthesis and Characterization of Crystalline Assemblies of Functionalized Hydrogel Nanoparticles

Access: Use of this item is restricted to the UNT Community
Two series monodispersed nanoparticles of hydroxylpropyl cellulose (HPC) and functionalized poly-N-isopropylamide (PNIPAM) particles have been synthesized and used as building blocks for creating three-dimensional networks, with two levels of structural hierarchy. The first level is HPC nanoparticles were made from methacrylated or degradable cross-linker attached HPC. These nanoparticles could be stabilized at room temperature by residual methacrylate or degradable groups are present both within and on the exterior of HPC nanoparticles. Controlled release studies have been performed on the particle and networks .The nearly monodispersed nanoparticles have been synthesized on the basis of a natural polymer of hydropropylcellulose (HPC) with a high molecular weight using the precipitation polymerization method and self-assembly of these particles in water results in bright colors. The HPC nanoparticles can be potential using as crosslinkers to increase the hydrogels mechanical properties, such as high transparency and rapid swelling/de-swelling kinetics. The central idea is to prepare colloidal particles containing C=C bonds and to use them as monomers - vinylparticles, to form stable particle assemblies with various architectures. This is accomplished by mixing an aqueous suspension of hydrogel nanoparticles (PNIPAM-co-allylamine) with the organic solvent (dichloromethane) to grow columnar crystals. The hydrogels with such a unique crystal structure behavior …

Reading Handel: A Textual and Musical Analysis of Handel's Acis and Galatea (1708, 1718)

Access: Use of this item is restricted to the UNT Community
The purpose of this dissertation is two-fold: one is to analyze the narratives of Acis and Galatea written by Ovid, and the two libretti by Handel's librettists including Nicola Giuvo (1708) and John Gay (1718) with John Hughes and Alexander Pope; the other is to correlate this textual analysis within the musical languages. A 1732 pastiche version is excluded because its bilingual texts are not suitable for the study of relationships between meaning and words. For this purpose, the study uses the structural theory- -mainly that of Gérard Genette--as a theoretical framework for the analysis of the texts. Narrative analysis of Acis and Galatea proves that the creative process of writing the libretto is a product of a conscious acknowledgement of its structure by composer and librettists. They put the major events of the story into recitative and ensemble. By examining the texts of both Handel's work, I explore several structural layers from the libretti: the change of the characterization to accommodate a specific occasion and the composer's response to contemporary English demand for pastoral drama with parodistic elements, alluding to the low and high class of society. Further, Polyphemus is examined in terms of relationships with culture corresponding to …

Temperature tolerances and predation susceptibilities of transgenic and wildtype zebra danios, Danio rerio.

Access: Use of this item is restricted to the UNT Community
Both the upper and lower temperature tolerances of red fluorescent protein transgenic zebra danios and wildtype zebra danios, Danio rerio, were significantly different via two different methods; however, all differences are small (< 1°C) and probably not ecologically important. The U.S. geographic distributions of both transgenic and wildtype zebra danios will not be restricted by their upper thermal tolerances, but will be limited to the southern and western portions of the U.S. by their lower thermal tolerances. Largemouth bass did not preferentially prey upon transgenic zebra danios compared to wildtype danios or wildtypes relative to a native fish. If transgenic or wildtype zebra danios are released into southern or western U.S. waters, it is possible they could be eliminated by predation.

In March 1942, the 2nd Battalion, 131st Field Artillery Regiment, 36th Division, surrendered to the Japanese Imperial Army on Java in the Dutch East Indies. Shortly after the surrender, the men of the 2nd Battalion were joined as prisoners-of-war by the sailors and Marines who survived the sinking of the heavy cruiser USS Houston. From March 1942 until the end of World War II, these men lived in various Japanese prison camps throughout the Dutch East Indies, Southeast Asia, and in the Japanese home islands. Forced to labor for their captors for the duration of the conflict, they performed extremely difficult tasks, including working in industrial plants and mining coal in Japan, and most notably, constructing the infamous Burma-Thailand Death Railway. During their three-and-one-half years of captivity, these prisoners experienced brutality at the hands of the Japanese. Enduring prolonged malnutrition and extreme overwork, they suffered from numerous tropical and dietary diseases while receiving almost no medical care. Each day, these men lived in fear of being beaten and tortured, and for months at a time they witnessed the agonizing deaths of their friends and countrymen. In spite of the conditions they faced, most survived to return to the United States …

Documentary Film: I Named Her Angel

Access: Use of this item is restricted to the UNT Community
Recent political developments in the world show us that different cultures need to know and understand each other better. Even though technological developments like the Internet, satellites, cable television and conglomeration of big media entities have made mass communication more effective and faster, we cannot easily say that these developments help to bring world cultures together. As a result, mass audiences are not very much able to see what few productions do speak to these issues in a constructive manner. The main aim of this documentary film project is to serve as a small step towards helping different cultures to understand each other better. This documentary film conveys the basics of Mevlevism by following the formal gatherings of a Mevlevi den in Istanbul, Turkey. A den or tekke is a place where Islamic people gather and perform their religious activities. During these gatherings they do the sema, they pray, they listen to music, and they discuss spiritual matters. Sema is the entire ritual they perform as part of their ceremonies including listening to music, singing and chanting to attain a state of religious emotion and ecstasy or vecd.

Leadership preferences of a Generation Y cohort: A mixed methods study.

Access: Use of this item is restricted to the UNT Community
Presently there are four generational cohorts in the workplace. Born from 1977 to 1997, the youngest cohort group, referred to as Generation Y (or Gen Y) in this study, has 81 million members, of whom over 29 million are already in the workplace. The importance of leader-subordinate relationships in the workplace has been confirmed; in recognizing this, leaders must identify and adapt to the changing era-shaped needs of employees, who cannot fully participate in organizational life if their most urgent needs are not being met. Because Gen Y employees are only now entering the workforce, little is actually known about the workplace needs of this cohort group. This study attempted to determine leadership needs of a Gen Y cohort as a means to enhance workplace relationships in the 21st century organization. A sequential, mixed methods study was employed to explore leadership preferences of a Gen Y cohort. Initially, focus group interviews were used to generate leadership themes. Based on these themes, an instrument was designed, and Gen Y business students from three higher education institutions were surveyed. Confirmatory factor analysis using LISREL software was used to test the themes. The driving force behind this research design was to build a …

Art Criticism and the Gendering of Lee Bontecou's Art, ca. 1959 - 1964

Access: Use of this item is restricted to the UNT Community
This thesis identifies and analyzes gendering in the art writing devoted to Lee Bontecou's metal and canvas sculptures made from the 1959 - 1964. Through a careful reading of reviews and articles written about Bontecou's constructions, this thesis reconstructs the context of the art world in the United States at mid-century and investigates how cultural expectations regarding gender directed the reception of Bontecou's art, beginning in 1959 and continuing through mid-1960s. Incorporating a description of the contemporaneous cultural context with description of the constructions and an analysis of examples of primary writing, the thesis chronologically follows the evolution of a tendency in art writing to associate gender-specific motivation and interpretation to one recurring feature of Bontecou's works.

Nutritional Labeling on Menus in Full-Service Restaurants: Consumer Attitudes and Intended Usage

Access: Use of this item is restricted to the UNT Community
Dining out has become an important part of the American lifestyle, greater frequencies as well as increased portion sizes have led to concern. The number of Americans that are classified as overweight or obese has also increased considerably, and the foodservice industry has become a target. Mandatory labeling of menu items has been avoided to this point, but the subject has moved to the forefront and continues to be debated. This study surveyed 502 patrons at a student-run restaurant in Texas. Respondents provided information concerning their health and dining habits as well as their attitudes toward and intended usage of nutritional information (NI) on menus in full-service restaurants. Gender, education levels, age, and household income affect the attitudes toward and intended usage of NI. Exercise frequency, the current use of nutritional information on packaged foods, and the practice of healthy eating habits are all related to the intended use of NI while dining out.

Perceptions of Postpartum Depression among Adolescent Mothers and the Social Construction of Related Stigma

Access: Use of this item is restricted to the UNT Community
Six serial focus groups were used to explore the perceptions of postpartum depression among nine adolescent mothers. The discussions were tape recorded, transcribed and analyzed using symbolic interaction theory, specifically Goffman's concept of stigma. Participants identified major stigma themes in relation to postpartum depression, teenage pregnancy and motherhood, all of which were portrayed negatively in the media. Several key causes of adolescent postpartum depression were also found including self esteem relating to poor body image and social support. The findings indicate a much needed change in the way adolescent mothers are identified and treated for postpartum depression. Additionally, the importance of social support in preventing and treating adolescent postpartum depression is highlighted and programs addressing such concerns must be implemented.

Treadmill validation of the Siconolfi step test.

Access: Use of this item is restricted to the UNT Community
Maximal oxygen uptake (VO2max) is the internationally recognized measure of a person's cardiorespiratory fitness. Currently the most accurate way of assessing one's true VO2max involves the use of maximal exercise tests, which require the use of specialized equipment, and are time consuming and costly. The purpose of this study was to determine the validity of the submaximal Siconolfi step test to estimate VO2max. A second purpose was to determine if body fat percentage improved the validity. Thirty-six individuals underwent a maximal treadmill test, in which VO2max was directly measured, and the step test. Results indicate that, although VO2max estimates generated by the Siconolfi step test are highly correlated to true VO2max (r =.887; p<.01), the values consistently underestimated a person's aerobic fitness. It was also determined that body fat percentage did not contribute to the prediction of VO2max.

Generalized identity matching in the pigeon: Effects of extended observing- and choice-response requirements.

Access: Use of this item is restricted to the UNT Community
Four experimentally naïve white Carneau pigeons learned to match three colors to each other in a variant of an Identity matching-to-sample procedure with an FR20 on samples and a response-initiated FI8-s on comparisons. In Experiment 1, the extent to which subjects were matching on the basis of identity was assessed by presenting, in extinction, test trials comprising novel stimuli serving as the sample (and matching comparison) or as the nonmatching comparison. The results from Experiment 1 suggested intermediate or little to no transfer on the basis of identity. Experiment 2 reassessed transfer on the basis of identity with differential reinforcement on the test trials. Under these conditions, two of the four birds demonstrated substantially better than chance levels of performance. These data imply that while the extended response requirements may be necessary, other procedural aspects may be responsible for generalized identity matching in the pigeon.
