An Analysis of the Ability of an Instrument to Measure Quality of Library Service and Library Success (open access)

An Analysis of the Ability of an Instrument to Measure Quality of Library Service and Library Success

This study consisted of an examination of how service quality should be measured within libraries and how library service quality relates to library success. A modified version of the SERVQUAL instrument was evaluated to determine how effectively it measures library service quality. Instruments designed to measure information center success and information system success were evaluated to determine how effectively they measure library success and how they relate to SERVQUAL. A model of library success was developed to examine how library service quality relates to other variables associated with library success. Responses from 385 end users at two U.S. Army Corps of Engineers libraries were obtained through a mail survey. Results indicate that library service quality is best measured with a performance-based version of SERVQUAL, and that measuring importance may be as critical as measuring expectations for management purposes. Results also indicate that library service quality is an important factor in library success and that library success is best measured with a combination of SERVQUAL and library success instruments. The findings have implications for the development of new instruments to more effectively measure library service quality and library success as well as for the development of new models of library service …

The Effects of Shaping and Instruction-based Procedures on Behavioral Variability during Acquisition and Extinction (open access)

The Effects of Shaping and Instruction-based Procedures on Behavioral Variability during Acquisition and Extinction

This study examined effects of two response acquisition procedures on topography of responding using the revealed operant technique and compared results to previous experiments on this topic. Subjects emitted 100 repetitions each of 4 response patterns on a continuous schedule of reinforcement. A 30-min extinction condition followed acquisition. One group of subjects learned the first response through a series of shaping steps designed to reduce acquisition variability. Another group of subjects was instructed in the correct response topography and was told there was no penalty for attempting other sequences. The first group of subjects produced high variability during extinction despite reduced variability in acquisition. The second group of subjects responded with moderate to high variability during extinction and little variability during acquisition. Most extinction responses for the first group were variations of the last pattern reinforced. Most extinction responses for the second group were repetitions of the last pattern reinforced.

Nobody's Fool: A Study of the Yrodivy in Boris Godunov (open access)

Nobody's Fool: A Study of the Yrodivy in Boris Godunov

Modest Musorgsky completed two versions of his opera Boris Godunov between 1869 and 1874, with significant changes in the second version. The second version adds a concluding lament by the fool character that serves as a warning to the people of Russia beyond the scope of the opera. The use of a fool is significant in Russian history and this connection is made between the opera and other arts of nineteenth-century Russia. These changes are, musically, rather small, but historically and socially, significant. The importance of the people as a functioning character in the opera has precedence in art and literature in Russia in the second half of the nineteenth-century and is related to the Populist movement. Most importantly, the change in endings between the two versions alters the entire meaning of the composition. This study suggests that this is a political statement on the part of the composer.

Scientific Considerations of Olestra as a Fat Substitute (open access)

Scientific Considerations of Olestra as a Fat Substitute

Olestra is, a sucrose polyester, a noncaloric fat substitute, made from sucrose and several fatty acid esters. It has been approved by the FDA as a food additive used in preparing low-fat deep-frying foods such as savory snacks. Available literature on olestra was evaluated that had both positive and negative connotations. Clinical trials in numerous species of animals including humans were conducted to determine if olestra would affect the utilization and absorption of macro- and micronutrients; the effects of olestra on growth, reproduction, or its toxicity were also examined. The roles of olestra as a fat substitute, how it could effect on humans and the environment, and the potential impacts from its use in large amounts were assessed. Olestra can be removed from the environment by aerobic bacteria and fungi which may be isolated from activated sludge and soils.

Performing "Camp, Vamp & Femme Fatale": Revisiting, Reinventing & Retelling the Lives of Post-Death, Retro-Gothic Women (open access)

Performing "Camp, Vamp & Femme Fatale": Revisiting, Reinventing & Retelling the Lives of Post-Death, Retro-Gothic Women

This thesis examines the production process for "Camp, Vamp and Femme Fatale," performed at the University of North Texas in April of 1997. The first chapter applies Henry Jenkins's theory of textual poaching to the authors' and cast's reappropriation of cultural narratives about female vampires. The chapter goes on to survey the narrative, cinematic and critical work on women as vampires. As many of the texts were developed as part of the fantasy role-playing game Vampire: The Masquerade, this chapter also surveys how fantasy role-playing develops unpublished texts that can make fruitful ground for performance studies. The second chapter examines the rehearsal and production process in comparison to the work of Glenda Dickerson and other feminist directors.

Goal Setting Strategies, Locus of Control Beliefs, and Personality Characteristics of NCAA Division IA Swimmers (open access)

Goal Setting Strategies, Locus of Control Beliefs, and Personality Characteristics of NCAA Division IA Swimmers

The purpose of the present study was to examine goal setting strategies, locus of control beliefs and personality characteristics of swimmers (108 males and 111 females) from top twenty 1999 NCAA Division IA programs. Three questionnaires were completed: (a) Goal Setting in Sport Questionnaire (GSISQ: Weinberg, Burton, Yukelson, & Weigand, 1993), (b) the Internal, Powerful Others, Chance Scale (IPC: Levenson, 1973), and (c) the compliance subscale and six conscientiousness subscales from the NEO Personality Inventory-Revised (NEO PI-R: Costa & McCrae, 1985). Descriptive statistics from the GSISQ indicated that most of the swimmers set goals to improve overall performance (51%) and set moderately difficult goals (58%). Results associated with the IPC scale revealed that most of the swimmers attributed their sport performance to internal factors. Results pertaining to the NEO-PI-R indicated that most swimmers were highly conscientious, disciplined, purposeful, and determined.

A Narrative Analysis of Korematsu v. United States (open access)

A Narrative Analysis of Korematsu v. United States

This thesis studies the Supreme Court decision, Korematsu v. United States, 323 U.S. 214 (1944) and its historical context, using a narrative perspective and reviewing aspects of narrative viewpoints with reference to legal studies in order to introduce the present study as a method of assessing narratives in legal settings. The study reviews the Supreme Court decision to reveal its arguments and focuses on the context of the case through the presentation of the public story, the institutional story, and the ethnic Japanese story, which are analyzed using Walter Fisher's narrative perspective. The study concludes that the narrative paradigm is useful for assessing stories in the law because it enables the critic to examine both the emotional and logical reasoning that determine the outcomes of the cases.

Cassette Systems for Creating Intergeneric Hybrid ATCases (open access)

Cassette Systems for Creating Intergeneric Hybrid ATCases

Cassette systems for creating intergeneric hybrid ATCases were constructed. An MluI restriction enzyme site was introduced at the carbamoylphosphate binding site within the pyrB genes of both Pseudomonas putida and Escherichia coli. Two hybrids, E. coli pyrB polar domain fused with P. putida pyrB equatorial domain and P. putida pyrB polar domain fused with E. coli pyrB equatorial domain, are possible. The intergeneric E. coli-P. putida hybrid pyrB gene was constructed and found to encode an active ATCase which complemented an E. coli Pyr- strain. These hybrids are useful for kinetic and expression studies of ATCase in E. coli.

Elasticity of Money as a Reinforcer: Assessing Multiple Compositions of Unit Price (open access)

Elasticity of Money as a Reinforcer: Assessing Multiple Compositions of Unit Price

Behavioral economics is the integration of concepts from micro-economics into behavior analysis. Most of the research in behavioral economics has been done with non-human subjects and with drugs as reinforcers. This study represents an extension of previous research to assess money as a reinforcer with humans as subjects. The participants in this study solved math problems to earn money at various unit prices. Results indicate that demand of money adhered to the law of demand in that consumption decreased as unit prices increased. An underlying assumption is that consumption should be equivalent at different compositions of unit price. Replications of either the same or different compositions of unit price indicated that there were some discrepancies in consumption in this study.

Development of a Coaxiality Indicator

Access: Use of this item is restricted to the UNT Community
The geometric dimensioning and tolerancing concept of coaxiality is often required by design engineers for balance of rotating parts and precision mating parts. In current practice, it is difficult for manufacturers to measure coaxiality quickly and inexpensively. This study examines feasibility of a manually-operated, mechanical device combined with formulae to indicate coaxiality of a test specimen. The author designs, fabricates, and tests the system for measuring coaxiality of holes machined in a steel test piece. Gage Repeatability and Reproducibility (gage R&R) and univariate analysis of variance is performed in accordance with Measurement System Analysis published by AIAG. Results indicate significant design flaws exist in the current configuration of the device; observed values vary greatly with operator technique. Suggestions for device improvements conclude the research.

A Descriptive Study of Students Who Were Accepted for Admission at West Texas A&M University But Did Not Enroll

Access: Use of this item is restricted to the UNT Community
Each year, institutions of higher education devote valuable financial and personnel resources in the hope of enhancing student recruitment and matriculation. The purpose of this study was to examine the demographic characteristics, the factors that influenced students’ decisions to apply for admission to a university, their educational intentions, and their reasons for not enrolling after they had been admitted. The subjects of the study were first-time freshmen accepted for admission to a mid-size, public, southwestern university who did not enroll for the fall 1997 semester. Statistically significant differences were found when comparing no-shows and enrolled students by gender, ethnicity, age, ACT/SAT score, and distance of their hometown from the university. There were more female no-shows, and more males enrolled than females; a greater percentage of no-shows reported the distance of their hometown to be more than 200 miles; and the mean test score for no-shows was higher. Factors important in the college selection process found to be statistically significant among the groups were: a greater percentage of Minorities than Caucasians reported the importance of the financial aid award or a scholarship offer; students living within 100 miles of the campus reported the proximity of the university as important, advice received …

Cure Kinetics and Processing Parameters of Neat and Reinforced High Performance Epoxy Resins: Evaluation of Techniques

Access: Use of this item is restricted to the UNT Community
Kinetic equation parameters for the curing reaction of a commercial glass fiber reinforced high performance epoxy prepreg composed of the tetrafunctional epoxy tetraglycidyl 4,4-diaminodiphenyl methane (TGDDM), the tetrafunctional amine curing agent 4,4’-diaminodiphenylsulfone (DDS) and an ionic initiator/accelerator, are determined by various thermal analysis techniques and the results compared. The reaction is monitored by heat generated determined by differential scanning calorimetry (DSC). The changes in physical properties indicating increasing conversion are followed by shifts in glass transition temperature determined by DSC and temperature-modulated DSC (TMDSC), thermomechanical (TMA) and dynamic mechanical (DMA) analysis and thermally stimulated depolarization (TSD). Changes in viscosity, also indicative of degree of conversion, are monitored by DMA. Thermal stability as a function of degree of cure is monitored by thermogravimetric analysis (TGA). The parameters of the general kinetic equations, including activation energy and rate constant, are explained and used to compare results of various techniques. The utilities of the kinetic descriptions are demonstrated in the construction of a useful time-temperature-transformation (TTT) diagram for rapid determination of processing parameters in the processing of prepregs.

Counselor Effectiveness and Correlations With Select Demographic Variables for Masters Level Counseling Students

Access: Use of this item is restricted to the UNT Community
Counselor education programs are charged with the responsibility to train students to be effective counselors. Despite relative consistency in academic and clinical experiences, some students are less effective than others. It was the intent of this research to investigate possible relationships which may exist between students' background and experiences and their levels of demonstrated counselor effectiveness as measured by the Counselor Rating Form - Short Version (CRF-S) and the Supervisor Rated-Counselor Interaction Analysis (SR-CIA). It was hypothesized that counselor effectiveness would be negatively correlated with prior teaching experience and level of religious participation. Data was collected using a demographic survey from masters level counseling students participating in their practicum semester. Counseling tapes from each of the participants were collected towards the end of the semester. These tapes were then rated by doctoral students using the CRF-S and the SR-CIA. The total sample size was 28. Regression analysis was used to investigate the hypotheses. Three models were constructed. The dependent variables used were scores from the CRF-S, the SR-CIA and a third comprised of a normalized composite of CRF-S and SR-CIA termed COMPOSITE. Each model used, as the independent variables, years of teaching experience, and hours of religious participation. Results from …

Hospitality Students' Attitudes and Behavioral Intentions toward Learning and Using Computer Technology

Access: Use of this item is restricted to the UNT Community
Following Ajzen/Fishbein's 1980 Theory of Reasoned Action, influences of hospitality students' external variables (age, gender, university classification, and work experience) on computer attitudes, and relationships between computer attitudes and intentions to learn and use computers were tested. A sample of 412 hospitality students completed two measurements: Loyd/Gressard's 1984 Computer Attitude Scale, and Behavioral Intentions to Learn and Use Computers. Males and females had positive computer attitudes. Graduates had more positive computer attitudes. No interaction effect existed between gender and classification. No relationships existed between age and work experience on computer attitudes. Computer attitudes positively correlated with intentions to learn and use computers. Results supported the Theory of Reasoned Action. External variables partially influence attitudes and attitudes influence intentions.

The Afro-British Slave Narrative: The Rhetoric of Freedom in the Kairos of Abolition

Access: Use of this item is restricted to the UNT Community
The dissertation argues that the development of the British abolition movement was based on the abolitionists' perception that their actions were kairotic; they attempted to shape their own kairos by taking temporal events and reinterpreting them to construct a kairotic process that led to a perceived fulfillment: abolition. Thus, the dissertation examines the rhetorical strategies used by white abolitionists to construct an abolitionist kairos that was designed to produce salvation for white Britons more than it was to help free blacks. The dissertation especially examines the three major texts produced by black persons living in England during the late eighteenth centuryIgnatius Sancho's Letters of the Late Ignatius Sancho (1782), Ottobauh Cugoano's Thoughts and Sentiments on the Evil of Slavery (1787), and Olaudah Equiano's The Interesting Narrative of the Life of Olaudah Equiano, or Gustavus Vassa, the African (1789)to illustrate how black rhetoric was appropriated by whites to fulfill their own kairotic desires. By examining the rhetorical strategies employed in both white and black rhetorics, the dissertation illustrates how the abolitionists thought the movement was shaped by, and how they were shaping the movement through, kairotic time. While the dissertation contends that the abolition movement was rhetorically designed to provide redemption, …

A Qualitative Study of the Use and Value of Financial Performance Indicators in Selected Community Colleges in the State of Texas as Perceived by their Chief Executive Officers

Access: Use of this item is restricted to the UNT Community
Throughout the United States, colleges and universities are faced with an increasing need for financial funding, while at the same time resources continue to diminish. With the limitations of available funds, community colleges must exhibit efficiencies in the operations of their institutions. External interests, such as governing boards and legislatures, require demonstration of efficient financial management. This evidence is then used to make decisions concerning future financial support for the community college. This study determined if community college chief executive officers use financial performance indicators as provided by the State Auditor's Office and if the chief executive officers of the community colleges value the compilation and the distribution of the financial performance indicators. In the selected colleges, many of the chief executive officers depend on their chief financial officer for understanding and application of financial performance indicators. The performance indicators distributed by the Auditor's Office captured only a snapshot of the college's performance, and failed to fully describe the whole college performance or specific financial events captured by the indicators. Though the indicators had flaws, either through incorrect data or lack of explanation, the CEOs did value their compilation because they provided a means for ‘getting the community college story' …

Techniques of Sensual Perception: The Creation of Emotional Pathways

Access: Use of this item is restricted to the UNT Community
Some artists strive to create artwork that has aesthetic value. If a piece of artwork has the ability to capture the attention of an audience, it must contain strong sensual attributes. Thus, understanding how to design an art form to contain strong sensual attributes may increase the possibility of an aesthetic experience. Since aesthetics is an experience of sensations perceived when in contact with a creative form in any artistic discipline, it is necessary for an artist to understand the nature of the sensual experience. In understanding the sensual experience, artists may be able to create techniques to enhance the aesthetic experience of their work. My video piece, entitled Ararat is a study of methods to enhance the sensual experience. I hope to accomplish this by means of using techniques that optimize an audience's perceptual experience.

The Relationship Between Time-On-Task in Computer-Aided Instruction and the Progress of Developmental Reading Students at the University of Texas at Brownsville and Texas Southmost College

This research sought to determine what relationship exists between time-on-task in computer-aided instruction (CAI) using Destinations courseware and progress in reading ability of developmental reading students as indicated by the reading portion of the Texas Academic Skills Program (TASP) test. Time-on-task is the time during which a student actively works on Destinations activities, as recorded by the software management system. TASP, an exam required of all students in Texas public colleges, assesses reading, math, and writing skills. The population was made up of 482 students who took the TASP exam before and after CAI and who used Destinations CAI for remediation of reading skills. Null hypotheses were explored using Pearson correlation and linear multiple regression. The findings for the null hypotheses were the following: Ho1 - Correlation and linear regression correlation showed that time-on-task in Destinations CAI had no significant effect on the TASP scores of the population studied. Ho2 - Correlation and linear regression correlation showed that females made significantly better gains on the TASP test from CAI than males. Ho3 - Correlation and linear regression correlation showed that low-achiever students made no better gains on the TASP test from time-on-task in CAI than high-achiever students.

The Luxury of Tears: A Secondary Survivor's Story

Access: Use of this item is restricted to the UNT Community
As the written accompaniment for The Luxury of Tears, a twelve-minute documentary video exploring the emotional impact of sexual assault on male survivors and their partners, this document examines the visual texts of both the fiction and nonfiction genres. Specifically, I contend that fiction film manufactures male survivorship with regard to rape events in such manner which contributes to the thematization of social silence. Such silence perpetuates the feminization of rape as a social problem, and dissolves the development of male survivor resources. A discussion of production processes, challenges, and resolutions is included.

Symmetrical Features of Nikolai Medtner's Language: The Grzovaya Sonata, Opus 53 No. 2

Access: Use of this item is restricted to the UNT Community
Nikolai Medtner's works evidence an intense interest in symmetrical designs. This concern is manifest at all levels, from the large scale proportions of his numerous ingenious sonata forms to the symmetrically constructed themes and motives. Medtner's works include several instances of palindromic themes and periods. Some palindromic contours are achieved through immediate inversion, creating expansive, symmetrical waves. One of Medtner's thumbprints, symmetrical contrary voice-leading, consists of two or more voices which systematically expand or contract in exact mirror fashion. The contrary movement is usually stepwise, and may be either chromatic or diatonic. Occasionally even larger intervals, such as thirds and fourths, are subjected to this favourite mirroring technique. Such symmetrical expansion and contraction often controls the harmonic progression of several consecutive bars. One of the most striking aspects of Medtner's music is his sophisticated harmonic language. He was fascinated with symmetrical harmonic designs, such as the tritone, the French sixth chord, and the octatonic scale, and made endless and increasingly intricate explorations into these stuctures and the ways in which these apparently nontonal, non-hierarchical forms could be coordinated with the fundamental hierarchy of asymmetrical tonal forms, including triads, major and minor scales, and tonic-dominant relations. Medtner's late work, the Grozovaya …
