Quantitative Analysis of the Gabaergic System in Cat Primary Somatosensory Cortex and Its Relation to Receptive Field Properties
Sensory neocortex contains a significant number of inhibitory neurons that use gamma-aminobutyric acid (GABA) as their neurotransmitter. Functional roles for these neurons have been identified in physiological studies. For example, in primary somatosensory cortex (SI), blockade of GABAa receptors with bicuculline leads to expansion of receptive fields (RFs). The magnitude of RF enlargement varies between SIpopulations of GABAergic neurons were identified by labeling specific calcium binding proteins. digital.library.unt.edu/ark:/67531/metadc279190/
Experimental Synchronization of Chaotic Attractors Using Control
The focus of this thesis is to theoretically and experimentally investigate two new schemes of synchronizing chaotic attractors using chaotically operating diode resonators. The first method, called synchronization using control, is shown for the first time to experimentally synchronize dynamical systems. This method is an economical scheme which can be viably applied to low dimensional dynamical systems. The other, unidirectional coupling, is a straightforward means of synchronization which can be implemented in fast dynamical systems where timing is critical. Techniques developed in this work are of fundamental importance for future problems regarding high dimensional chaotic dynamical systems or arrays of mutually linked chaotically operating elements. digital.library.unt.edu/ark:/67531/metadc278971/
Was Ist Silvia? Englanderin Oder Deutsche? Restoring the Orignial English Texts to Songs Schubert Set in Translation, a Lecture Recital, Together with Three Recitals of Selected Works of H. Purcell, G. F. Handel, W. A. Mozart, F. Schubert, J. Brahms, H. Wolf, F. Poulenc and Others
Because of the lack of information concerning the success or failure of Schubert's bilingual edition and concerning the relationship between the English texts and Schubert's settings, most performers take the conservative route of performing both the songs from Lady of the Lake and the rest of Schubert's English song repertoire only with the German translations. Because of the desirability of performing this repertoire in English for English-speaking audiences, this study examines all of the English songs of Schubert to determine whether the original poems can be successfully substituted for the German translations. Editions of the settings that can be effectively performed with the English texts are included in the appendix, in order to make available editions which reflect Schubert's ambition to make his songs easily accessible to non-German-speaking audiences. digital.library.unt.edu/ark:/67531/metadc279276/
A Recommended Curriculum for Teaching Score Study in the Undergraduate Instrumental Conducting Class
The purpose of this study was to create and gain consensus of an essential curriculum for teaching score study in the undergraduate instrumental conducting class. Questions to be answered by this study were what methods, materials, and evaluations should be used to teach score study to undergraduate instrumental conducting students? Resolving the questions required the collection of information on the methods, materials, and evaluations used in teaching score preparation in the undergraduate instrumental conducting class and the opinions of conductors and teachers of conducting about those methods, materials, and evaluations. digital.library.unt.edu/ark:/67531/metadc279291/
The Condition of the Southern Baptist Professoriate : A Comparison with the Carnegie Foundations 1989 National Survey of Faculty
Southern Baptist-Related college faculty attitudes and opinions on areas of higher education most important to the professoriate as identified by the Carnegie Foundation in its 1989 National Survey of Faculty are described in this study and compared with the data from the survey reported by the Carnegie Foundation in The Condition of the Professoriate: Attitudes and Trends, 1989 and Scholarship Reconsidered: Priorities of the Professoriate. The data were compared in the eight areas: goals of collegiate education, academic standards, attitudes about student life, teaching, research, and service, status of the profession, views of the institution, participation in decision-making, and general observations of higher education. digital.library.unt.edu/ark:/67531/metadc279234/
Computer Simulation Placements in a Unit of Instruction
Educators considering implementing a computer simulation must decide on the optimum placement of the simulation in the unit of instruction to maximize student learning. This study examined student achievement using two different placements for the computer simulation, The Civil War, in a unit of instruction of 8th grade American History students in a suburban middle school. digital.library.unt.edu/ark:/67531/metadc278685/
Policies and Practices of University Presses in Texas
The purposes of this study were: (a) to present a brief history of university press publishing in Texas, (b) to describe operating policies and practices of these presses, (c) to compare these policies and practices with commonly accepted principles of publishing policy, and (d) to provide a view of the future of university press publishing in Texas. digital.library.unt.edu/ark:/67531/metadc279306/
A Comparison of Three Criteria Employed in the Selection of Regression Models Using Simulated and Real Data
Researchers who make predictions from educational data are interested in choosing the best regression model possible. Many criteria have been devised for choosing a full or restricted model, and also for selecting the best subset from an all-possible-subsets regression. The relative practical usefulness of three of the criteria used in selecting a regression model was compared in this study: (a) Mallows' C_p, (b) Amemiya's prediction criterion, and (c) Hagerty and Srinivasan's method involving predictive power. Target correlation matrices with 10,000 cases were simulated so that the matrices had varying degrees of effect sizes. The amount of power for each matrix was calculated after one or two predictors was dropped from the full regression model, for sample sizes ranging from n = 25 to n = 150. Also, the null case, when one predictor was uncorrelated with the other predictors, was considered. In addition, comparisons for regression models selected using C_p and prediction criterion were performed using data from the National Educational Longitudinal Study of 1988. digital.library.unt.edu/ark:/67531/metadc278764/
Accounting Measurement Bias and Executive Compensation Systems
This dissertation presents empirical evidence intended to help answer two research questions. The first question asks whether executive compensation systems appear to exploit the bias in accounting-based performance measures in order to reduce the volatility in executive compensation and to allocate incentives more effectively across the range of activities performed by the executive. The second question asks whether compensation systems systematically differ between firms that use alternative accounting methods and whether any such systematic difference helps explain accounting choice. Parameters estimated in fixed-effects endogenous switching regression models were used to test the risk-shielding and incentive-allocation hypotheses. The models were estimated across a dataset consisting of 1151 executive-year observations of annual compensation paid to 222 top-level executives in 40 oil and gas firms. The dataset was partitioned by accounting method and separate models estimated for the full cost and successful efforts partitions. The tests provided modest support for the risk-shielding and incentive-allocation hypotheses, revealing that accounting measurement bias is used to focus incentives for effort in the exploration activity and to reduce executives' exposure to production risk. The design also allowed an estimate of the proportional change in compensation that was realized from the accounting choice actually made. digital.library.unt.edu/ark:/67531/metadc278949/

Interactions of Presentation Formats and Decision-Maker Characteristics upon Multiple Decision-Making Tasks: an Experiment Using Multiple Cognitive Assessments
Information systems research tends to ignore individual differences in users. This laboratory experiment sought to illuminate contributions of decision-makers' cognitive processes to decision outcome as reflected in four hypothesis sets: the impact of imagery preference and presentation format upon (HI) recall accuracy and upon hemispheric activation during (H2) encoding and (H3) recall, and (H4) to examine the relationship between hemispheric activation differences and accuracy differences. Point-value (specific values) and intraset-pattern (relationships between values) recall were considered. Thirty MBA students, grouped by imagery preference (cognitive style) as favoring verbal (textual) or visual (graphical) information presentation, performed computer-based recall tasks using tabular and graphical formats in a repeated measures design. Hemispheric activation (cognitive process) was assessed using ratios of EEG activity in six frequency bands captured from six pairs of homologous electrode sites during encoding and recall. digital.library.unt.edu/ark:/67531/metadc278785/
Implementation of the Middle School Concept: a Profile of Perceived Effects
This study addressed the perceptions of teachers, parents, and students in a suburban middle school about the effects of implementation of the middle school concept on instruction, peer group interaction, teacher attitudes and practices, and school culture. A qualitative approach was used for this study. Interview questions were developed to determine perceptions about effects in the areas identified in the research questions. Interviews were conducted with selected teachers, parents, and students who had exposure to the school before and after planned changes were implemented. Documents were examined for evidence of perceptions in the four areas identified. In addition, an existing data set (a student survey} was examined and the same survey was administered to a more recent group of students to identify possible patterns in student perceptions. digital.library.unt.edu/ark:/67531/metadc279214/
A Qualitative Study of Nine Elementary Principals Providing Inclusion for the Differently Abled
This is a qualitative description of the decision making processes that nine elementary principals use in determining campus level services for the differently abled and of how their administrative styles and values impact those decisions. Both the literature on leadership and on special education inclusion are reviewed. This review creates the framework in which the research questions are examined and structures the reporting of the findings. The defining attributes of leadership styles in conjunction with the defining attributes of inclusion are the heart of this study. Audiotaped interviews with each principal provide the data related to questions of leadership style, decision making, philosophy and autonomy. Separate site visits in which teachers from both regular and special education are queried as to the actual practices on their respective campuses and to their reactions to program changes involving the differently abled students. The combination of data gathered from the principal interviews, from the site visitations and the use of triangulation of data provide the basis for the findings. digital.library.unt.edu/ark:/67531/metadc279287/
The Role of Contract Training by Academic Institutions in Corporate Education and Training Programs
This study explored the role of contract training provided by North Texas higher education institutions in the education and training programs administered by area businesses employing more than 100 people. A survey instrument was mailed to corporate trainers that were members of the Dallas Chapter of the American Society of Training and Development in businesses employing more than 100 people. A total list of 292 trainers generated 71 usable responses. The purposes of this study were to: (a) determine the extent to which corporations use academic institutions for contract training, (b) determine the academic institutions in North Texas that training managers in the Dallas area believe are suitable contract training partners, (c) identify what subject areas are perceived as top educational priorities by training managers and are perceived to be suitable for contract training by academic institutions, (d) determine educational and training subjects for which corporations would be willing or prefer to utilize contract training by academic institutions, and (e) identify the subjects in which corporations currently use contract training by academic institutions. digital.library.unt.edu/ark:/67531/metadc279355/
A Case Study of the Use of Activity-Based Analysis as an Information Resource Management Tool
The purpose of the study was to investigate a modification of a managerial accounting technique, Activity-Based Costing (ABC), as a tool for addressing Information Resource Management (IRM) concerns within business processes. To indicate that ABC has been adapted for the IRM context, this study called the tool "Activity-Based Analysis" (ABA). ABA includes ABC's costing methodology as well as additional methods to address broader issues. The research method was a single-site case study at a property and casualty insurance company. The unit of analysis was a business process consisting of activities needed to provide claims handling services for workers' compensation insurance. Four questions guided the study: 1. Did ABA identify management information required to monitor process effectiveness and efficiency? 2. Did ABA support outsourcing decision making by identifying IRM cost components within business processes? 3. Did ABA identify information resources; that are sharable? 4. Did ABA identify differences between Company organizational characteristics andIRM department organizational characteristics? digital.library.unt.edu/ark:/67531/metadc279172/
The Effect of Hand-Held Weights and Exaggerated Arm Swing on Heart Rate, Blood Pressure, and Ratings of Perceived Exertion during Submaximal Walking
The purpose of this study was to investigate the effect of hand-weights and exaggerated arm swing on heart rate, blood pressure, and ratings of perceived exertion during submaximal walking. Twenty middle-aged (40- 59 years) female volunteers were given four submaximal treadmill tests at 3.0 mph and 0 grade. The four treatment conditions were as follows: 1) walking with unexaggerated arm swing (AS); 2) walking with unexaggerated arm swing with hand-held weights (ASHW); 3) walking with exaggerated arm swing (EAS), and 4) walking with exaggerated arm swing with hand-held weights (EASHW). The testing sequence was randomized and a minimum of 48 hr was given between tests. digital.library.unt.edu/ark:/67531/metadc279087/
An Investigation of Young Children's Awareness of Line and Line Quality in Art and Graphic Reproductions
The purpose of this study was to determine whether kindergarten children possess the ability to recognize, match, and discuss lines and line qualities. Using graphics and art reproductions, three matching tasks were constructed which examined young children's awareness of the line qualities of length, width, straightness, direction, movement, and uniformity. Graphics and art reproductions were also used to construct two tracing tasks employed to examine young children's awareness of actual and implied lines. The tasks were administered to 69 kindergarten students from four elementary schools in a public school district in the north central Texas area. digital.library.unt.edu/ark:/67531/metadc278901/
Memory and Attention in the Healthy Elderly
This study investigated the influence of age and health status on verbal and visual memory and attention. The objective was to select subjects resembling participants in normative studies, and to contrast the genuinely healthy component with the "contaminants." A rigorous and detailed self-report of health status plus a standard neurological examination were used to screen and divide subjects into two health status groups: normal and super healthy. It was speculated that the strong effect of age on memory and attention commonly found among the elderly would be diminished with more restrictive control over health status. digital.library.unt.edu/ark:/67531/metadc278970/
Multifractal Measures
The purpose of this dissertation is to introduce a natural and unifying multifractal formalism which contains the above mentioned multifractal parameters, and gives interesting results for a large class of natural measures. In Part 2 we introduce the proposed multifractal formalism and study it properties. We also show that this multifractal formalism gives natural and interesting results when applied to (nonrandom) graph directed self-similar measures in Rd and "cookie-cutter" measures in R. In Part 3 we use the multifractal formalism introduced in Part 2 to give a detailed discussion of the multifractal structure of random (and hence, as a special case, non-random) graph directed self-similar measures in R^d. digital.library.unt.edu/ark:/67531/metadc279084/
Protecting Patriarchy: an Historical/Critical Analysis of Promise Keepers, an All-Male Social Movement
The historical survey of social movements in the United States reveals that the movement is a rhetorical ground occupied by groups who have been marginalized by society. Today, however, the distinctions between those who are marginalized and those who are part of the establishment have become difficult to distinguish. This study considers the emergence of Promise Keepers, an all-male social movement, and the rhetorical themes that emerge from the group. This study identifies five rhetorical themes in Promise Keepers. These themes include asserting authority of men in the home and church, the creation of a new male identity, sports and war rhetoric, political rhetoric, and racial reconciliation. The implications of these themes are considered from a critical perspective and areas for future research are provided. digital.library.unt.edu/ark:/67531/metadc278756/
Assessment of Malingering in a Jail Referral Population : Screening and Comprehensive Evaluation
Psychological assessment of mentally disordered offenders requires a systematic consideration of response styles, including malingering and defensiveness. Important components of these evaluations are standardized diagnostic interviews. However, the ability of offenders to feign mental disorders on such measures to achieve such external incentives as treatment, placement on safer units, or possible release from jail remains uninvestigated. With a known-groups comparison with the data from the Structured Interview of Reported Symptoms as a criterion, 24 suspected malingerers were compared to 64 genuine patients on the Schedule of Affective Disorders and Schizophrenia (SADS), the abbreviated SADS-C, the Suicide Probability Scale, and the Referral Decision Scale. digital.library.unt.edu/ark:/67531/metadc278712/
A History of the Administrative Development and Contributions of the Federation of North Texas Area Universities, 1968-1991
The Federation of North Texas Area Universities was mandated by the Coordinating Board of the Texas College and University System on 3 December 1968, and this consortium was given legal empowerment by the Texas State Legislature. The three federated Universities--North Texas State University, Texas Woman's University and East Texas State University--developed a plan of cooperative action to maximize use of available resources, a plan which included sharing facilities and faculty as well as developing joint program offerings. At a time in history when educational institutions were obliged to maximize their resources, minimize their expenditure, and eliminate duplication, the consortium was an innovative approach to higher education as well as an interesting alternative to having degree programs cut and funding diminished. digital.library.unt.edu/ark:/67531/metadc278728/

The Role of Individuation Processes in the Launching of Children into Adulthood
The purpose of this study was to examine the extent to which levels of individuation and separation in adulthood would predict adjustment to the empty nest transition. Two-hundred and twenty-seven adults (M age = 48) who had experienced the empty nest within the last year completed a battery of scales assessing individuation from family of origin, spouse, and children as well as measures of adjustment, role strain, coping, and sex role attitudes. MANOVAS and hierarchical regression analyses suggested that levels of individuation from one's family of origin, spouse, and children differentially affect one's adjustment to, and coping with, the experience of launching of the youngest child from the home. Empty nest parents who are less differentiated from their own parents, from their spouses, and from their children reported a more negative impact of the empty nest in terms of more overall stress and role strain, more negative mood, and less life satisfaction than did empty nest parents who were more differentiated with regard to parents, spouse, and children. Results regarding the impact of individuation on empty nest adjustment regarding sex role attitudes were less clear cut, and may reflect cohort differences in work role opportunities for women and a parallel redefinition of the work role/parent role dichotomy for men. The data also suggest that women and men experience the empty nest transition differently, with women experiencing more distress and negative mood, supporting the notion that women, who define themselves in a context of relationship may experience more distress at a time when significant relationships are in flux. However, additional results which indicated significantly more proactive and adaptive coping strategies for women as compared to men suggest that women can meet the demands of the new definitions of themselves and their relationships in a relatively positive and adaptive way. The results suggest that present as well as past experiences of separation and individuation impact how one experiences and copes with the empty nest. The findings lend support to the importance of early, successful individuation experiences as possible precursors of how successfully individuals negotiate other developmental experiences involving separation and loss. digital.library.unt.edu/ark:/67531/metadc278703/
Compulsive Sexual Behavior and Personality Characteristics : A Comparative Analysis
The purpose of the present study was to compare the scores of the Beck Depression Inventory, State-Trait Anxiety Inventory, and the Coopersmith Inventory of heterosexual men with compulsive sexual behavior (N = 22), homosexual men with compulsive sexual behavior (N = 19), heterosexual men without compulsive sexual behavior (N = 38), and homosexual men without compulsive sexual behavior (N = 8). The Sex Addiction Screening Test was used to determined placement in a group. Findings revealed men who exhibit compulsive sexual behavior are significantly more depressed, experience lower self-esteem and have higher state anxiety (situational) than controls. digital.library.unt.edu/ark:/67531/metadc278767/

Control over Therapist Interactions as a Reinforcer for a Child with Autism
This study evaluated whether therapist terminations of social interactions would decrease social terminations and increase social initiations during play activities with a child with autism. The assessment took place in two conditions. The first condition, instructed involved social interactions with instructions delivered, and the second, uninstructed, involved social interactions without instructions delivered. These conditions were analyzed with a multiple baseline across-conditions design. Interaction duration, initiations, instructions, and child terminations were recorded. This study showed that the therapist-removal procedure resulted in a complete decrease in child terminations, and an increase in the number of initiations and the duration of the child-therapist interactions during the uninstructed condition. Similar effects were seen in the instructed condition, but to a lesser degree. digital.library.unt.edu/ark:/67531/metadc278765/
A Data Acquisition System Experiment for Gas Temperature and Pressure Measurements on a Liquid-Nitrogen-Powered Vehicle
A data acquisition system was set up to measure gas temperatures and pressures at various points on a liquid-nitrogen-powered vehicle. The experiment was attempted to develop a data acquisition method for applications on engines that use liquid air as the fuel. Two thermocouples and a pressure transducer were connected using data acquisition instruments interfaced to a laptop computer to acquire data. digital.library.unt.edu/ark:/67531/metadc278790/
Transcendentalism and Intertextuality in Charles Ives's War Songs of 1917
This thesis examines a collection of three songs, "In Flanders Fields," "He Is There!," and "Tom Sails Away," written by Charles Ives in 1917, from primarily a literary perspective involving Transcendentalism and intertextuality. Ives's aesthetic builds upon the principles of Transcendentalism. I examine these songs using the principles outlined by the nineteenth-century Transcendentalists, and Ives's interpretations of these beliefs. Another characteristic of Ives's music is quotation. "Intertextuality" describes an interdependence of literary texts through quotation. I also examine these songs using the principles of intertextuality and Ives's uses of intertextual elements. Familiarity with the primary sources Ives quotes and the texts they suggest adds new meaning to his works. Transcendentalism and intertextuality create a greater understanding of Ives's conflicting views of the morality of war. digital.library.unt.edu/ark:/67531/metadc278789/
The Effects of Raising Grandchildren on the Marital Satisfaction, Life Satisfaction, and Parenting Stress of Grandparents
This study examined the relationship among the variables of marital satisfaction, life satisfaction, and parenting stress of grandparents raising grandchildren and whether the sources and levels of marital satisfaction, life satisfaction, and parenting stress differed among grandparents raising grandchildren and grandparents not raising grandchildren. digital.library.unt.edu/ark:/67531/metadc278743/
A Comparison of Teachers' Sense of Efficacy of Traditionally and Alternatively Certified First Year Teachers
The purpose of this study was to compare the self-efficacy of two groups of first year teachers working in a large urban school district in North Texas. Twenty-eight of the participants were certified teachers. Ten participants held college degrees unrelated to teaching and were undergoing an alternative certification process. The Teacher Efficacy Scale was administered at the beginning and the end of the school year. Data from this scale was analyzed to determine if there were differences between the regular certification teachers and the alternative certification teachers at the beginning and the end of the school year, and to determine if their sense of efficacy changed over the course of the school year. digital.library.unt.edu/ark:/67531/metadc278702/

Language Contact in the Inner City: the Acquisition of AAVE Features by Bilingual Hispanic Adolescents
Sociolinguists working in Northern urban areas have shown that Hispanics who come in contact with African Americans sometimes acquire features of African American vernacular English (AAVE). However, the acquisition of AAVE features by Hispanics in the South has yet to be documented. Specifically, no one has studied the kind of English that Hispanics in Texas are acquiring. The present study investigates this issue through research in an inner-city area of Dallas: Oak Cliff. During the past twenty-five years, the population of Oak Cliff has changed from a largely African American community to include a substantial number of Hispanics. Though their neighborhoods remain fairly separate, sports and gangs provide an arena for extended contact. This study investigates the extent to which AAVE grammatical features are being acquired by bilingual Hispanic adolescents who hang out with African Americans. The analysis for this paper focuses on the relationship between contact and depth of acquisition of AAVE syntactic constraints on the use the copula (is/are, be). Preliminary results show that be+V+ing as an habitual form has been incorporated into the grammar of these subjects, suggesting fundamental changes towards an AAVE grammatical system. digital.library.unt.edu/ark:/67531/metadc279116/
The Effect of Job Congruency and Discrepancy with the National Athletic Trainers Association Athletic Trainer Role Delineation on the Job Characteristics Model of Work Redesign in Secondary School Athletic Trainers in Texas

The work consists of five parts of a mass, the Processional, Kyrie, Alleluia!, Hosanna!, and Recessional, with texted sections being taken from the Latin mass. The work is intended for a sacred wedding service of any denomination. The work was composed with the traditional aspects of the Latin mass in combination with a contemporary setting. digital.library.unt.edu/ark:/67531/metadc279062/
Protection or Equality? : A Feminist Analysis of Protective Labor Legislation in UAW v. Johnson Controls, Inc.
This study provides a feminist analysis of protective labor legislation in the Supreme Court case of UAW v. Johnson Controls, Inc. History of protection rhetoric and precedented cases leading up to UAW are provided. Using a feminist analysis, this study argues that the victory for women's labor rights in UAW is short lived, and the cycle of protection rhetoric continues with new pro-business agendas replacing traditional justifications for "protecting" women in the work place. The implications of this and other findings are discussed. digital.library.unt.edu/ark:/67531/metadc279082/
An Assessment of College Students' Attitudes and Empathy toward Rape
The purpose of this study was to assess rape attitudes and empathy levels of students at a university in North Texas. The Attitudes Toward Rape questionnaire and the Rape Empathy Scale were administered to 387 undergraduate students. Dependent variables were attitudes and empathy and independent variables were prior knowledge or experience as a rape victim, having female siblings, gender, marital status, and age. Significance was found between rape-intolerant attitudes and both prior experience as a victim (p < .001), and gender (p < .001). Significance was also found between empathy and experience as a rape victim (p < .035) and gender (p < .032). digital.library.unt.edu/ark:/67531/metadc279015/
Construction of a Physical Map of Moraxella (Branhamella) catarrhalis Strain ATCC25238
In order to gain a better understanding of this microorganismand its role in human pathogenesis, a physical map of Moraxella catarrhalis type strain ATCC25238 was constructed using pulsed field gel electrophoresis (PFGE) in combination with Southern hybridization techniques. Restriction endonucleases Not I, Rsr II, and Sma I were used to digest the chromosomal DNA. An overlapping circular map was generated by cross-hybridization of isolated radiolabeled fragments of Moraxella catarrhalis genomic DNA to dried PFGE gels. The number and location of the 16S and 23S ribosomal RNA genes were determined by digestion with l-Ceul enzyme and by Southern hybridization. Virulence-associated genes, the gene for β-lactamase, and housekeeping genes were also placed onto the physical map. digital.library.unt.edu/ark:/67531/metadc279104/
Development and Validation of a Two Factor Model of Adult Career Orientation
Subjects in this study were 5,523 respondents from a survey which was sent to households throughout the United States. The purpose of this study was to examine two basic components of career orientation: career indecision and career insight. Correlational analyses found relationships between career indecision and average job tenure, industry leaving intentions, industry staying intentions, and job satisfaction. Correlational analyses found relationships between career insight, industry staying intentions and job satisfaction. Multiple regression analyses were run using both career indecision and career insight as independent variables found that they had useful levels of incremental validity in predicting industry leaving intentions and job satisfaction. Potential uses of the two-dimensional career indecision - career insight model are discussed. digital.library.unt.edu/ark:/67531/metadc279120/
Development and Application of an Assessment Protocol for Watershed Based Biomonitoring
With numerous bioassessment methodologies available, a regional protocol needs to be developed to ensure that results are comparable. A regional assessment protocol was developed that includes collecting five benthic macroinvertebrate samples, identifying organisms to genus, and calculating the following metrics: Number of Taxa, Total Number of Individuals, Simpson's Diversity Index, Shannon's Diversity Index, Percent Contribution of Dominant Taxa, Hilsenhoffs Biotic Index, and Percent Contribution of Dipterans. Once the protocol was developed, it was used to assess the Bayou Chico tributaries and watershed. All three tributaries had been significantly impacted by human activity as had the watershed as a whole. This study indicates that a regional protocol could be developed and is appropriate for biomonitoring at the watershed scale. digital.library.unt.edu/ark:/67531/metadc279219/
Non-Academic Institutional Variables Related to Degree Completion of Non-Traditional Age Undergraduate Students
A study was conducted at The University of Texas at Arlington to obtain measurements of non-traditional age undergraduate students using the Mattering Scales for Adult Students in Higher Education (MHE). The MHE is designed to assess the perceptions of adult students on how much they matter to the institution they are attending. The study also sought to determine if "mattering" and other selected nonacademic variables associated with the university environment are perceived by nontraditional age students to effect their likelihood of completing their baccalaureate degree. Of the five subscales surveyed by the MHE, significant statistical differences were found to exist in the Administration, Interaction With Peers, Multiple Roles, and Faculty subscales denoting an interaction between gender and minority status. Significant statistical differences were also found by gender on the Advising subscale and by minority status on the Faculty subscale. digital.library.unt.edu/ark:/67531/metadc279269/
Market Timing, Forecast Ability and Information Flow in Petroleum Futures Markets
Three petroleum futures contracts are examined over a ten-year period from 1986 to 1996. Intertemporal changes in futures prices and the net open interest positions of three trader types are compared to determine what, if any, market timing ability the traders have. Seasonal variation is considered and a simple trading rule is adopted to determine the dollar-return potential for market participation and shed light on issues of market efficiency. digital.library.unt.edu/ark:/67531/metadc278807/
University-industry Alliances : A Study of Faculty Attitudes Toward the Effects of Alliances on the Governance and Operations of Institutions of Higher Education
The central purpose of this study was to compare the attitudes of faculty in applied sciences to the attitudes of faculty in liberal arts and other selected fields to determine if they differ significantly from each other in their perceptions of the effects of university-industry alliances on campus governance and operations. Secondary purposes were (a) to appraise the debate on alliances and the effects of alliances on academic values and (b) to contribute to the literature concerning alliances and their potential for improving higher education. digital.library.unt.edu/ark:/67531/metadc279159/
Military Spending, External Dependence, and Economic Growth in Seven Asian Nations: a Cross-National Time-Series Analysis
The theme of this study is that seven major East Asian less developed countries (LDCs) have experienced "dependent development," and that some internal and external intervening factors mattered in that process. Utilizing a framework of "dependent development," the data analysis deals with the political economy of development in these countries. This analysis supports the fundamental arguments of the dependent development perspective, which emphasize positive effects of foreign capital dependence in domestic capital formation and industrialization in East Asian LDCs. This perspective assumes the active role of the state, and it is found here to be crucial in capital accumulation and in economic growth. This cross-national time-series analysis also shows that the effects of external dependence and military spending on capital accumulation and economic growth can be considered as a regional phenomenon. The dependent development perspective offers a useful way to understand economic dynamism of East Asian LDCs for the past two decades. digital.library.unt.edu/ark:/67531/metadc279398/
Motion Versus Non-Motion in Interactive Video Lessons in High School Physical Science
The most important question addresed in this study was whether there is any difference in student learning between a motion group and a non-motion group. The interactive video courseware is currently a part of the curriculum in this district. It was used in its original form with the contrast group. For the experimental group one unit of the courseware was modified to remove the motion video and replace it with photorealistic graphics that served as the non-motion part of the study. Covariates were selected to compensate for any differences in the two groups. A pretest and posttest was administered to both groups. Analysis of the posttest scores indicated that there was no difference in learning if motion in the presentation was the only variable. digital.library.unt.edu/ark:/67531/metadc279141/
Critical Thinking Skills Related to Pre-Clinical Medical School Course Examinations
The major purpose of this study was to determine if pre-clinical medical school course examinations reflect critical thinking skills. The entire second year class from a medical school in the southwest made up the population. Student examination results from the first two years as well as scores on the Watson-Glaser Critical Thinking Appraisal were used in this study. digital.library.unt.edu/ark:/67531/metadc279394/
Linkage of Business and Manufacturing Strategies as a Determinant of Enterprise Performance: an Empirical Study in the Textile Industry
The main question in this study was: do business units that exhibit a "linkage" or "fit" between their business strategy and manufacturing strategy variables, outperform competitors who lack such a fit? This exploratory research focused on two business strategies: cost leadership and differentiation. Based on existing literature, twenty-four hypotheses concerning the relationship between business strategy and selected manufacturing strategy variables were developed. The manufacturing executives of eighty-eight broadwoven cotton fabric mills (SIC 2211) were surveyed using a qualitative questionnaire. Two sets of comparisons were made between the manufacturing strategy variables of the sampled firms: first, high vs. low performers pursuing cost leadership strategy; and second, high vs. low performers focusing on differentiation strategy. Within each set of comparisons, high performers reported linkage between their business strategies and selected manufacturing strategy variables. This study re-affirms the importance of linking business strategy with manufacturing strategy variables as a forceful weapon for overcoming competition. digital.library.unt.edu/ark:/67531/metadc278687/
The Relationship Between the Grief Process and the Family System: The Role of Affect, Communication, and Cohesion
Sixty-six people who had recently experienced the death of a parent or a spouse completed a questionnaire packet to assess their current grief symptomatology and some characteristics of the relationships within their family. Participants were asked to fill out a questionnaire 4-5 weeks after the death and then again six months later. The present study compared two competing models to explain whether the grief process affects the characteristics of relationships within the family system or that family characteristics affect the experienced grief symptoms. digital.library.unt.edu/ark:/67531/metadc279027/
