Analyzing Learner Characteristics, Undergraduate Experience and Individual Teamwork Knowledge, Skills and Abilities: Toward Identifying Themes to Promote Higher Workforce Readiness
With the world amidst globalization and economic flux affecting business, industry, and communities the need to work together becomes increasingly important. Higher education serves an important role in developing the individual teaming capabilities of the workforce. This environment is the time and place - opportunity for student personnel to develop these capabilities. This multiple case study utilized the analysis phase (learner, setting and job) of an instructional design model to analyze learner characteristics, the higher education environment/undergraduate experience, and the job/skills associated with individual teamwork knowledge, skills, and abilities of students from a senior cohort of the TRiO - SSS Project at a public student-centered research institution. The results yielded themes to promote the development of target populations individual teamwork KSAs which should increase their readiness to meet the teaming demands of today's employers. With an engaging undergraduate experience, inclusive of interaction with faculty members and collaborative learning with their peers, structured opportunities to practice individual teamwork KSAs in a work setting or internship, these underrepresented students may be an asset that is needed to meet the global workforce needs and fill civic capacities in their home communities. digital.library.unt.edu/ark:/67531/metadc11044/
Cognitive Dysfunction in Middle-Aged Adults vs. Older Adults with Obstructive Sleep Apnea
The presence of cognitive deficits in obstructive sleep apnea (OSA) is well-documented. Specifically, short- and long-term memory, attention/vigilance, and executive function (e.g. processing speed, mental flexibility, and problem solving) are affected. Cognitive deficits in aging occur in similar areas (i.e., memory and processing speed). Given that a greater percentage of older adults experience sleep-disordered breathing as compared to middle-aged adults, it is possible that OSA may account for some of the deficits typically attributed to aging. This study investigated this hypothesis by comparing middle-aged and older adults with and without OSA on computer-based measures of cognitive performance. No effect of OSA or an interaction between OSA and age on cognitive function was found; an effect of age on processing speed, distinguishing stimuli rapidly, attention, spatial ability/mental flexibility, and both working memory and short-term visual memory was found. This study also explored whether or not cognitive function may be improved in persons with OSA by re-assessing those participants one month after treatment. An effect of treatment on improvements on processing speed, distinguishing stimuli rapidly, mental flexibility, and short term memory was found. Overall, findings reflect the ability of treatment to improve cognitive function among OSA patients, regardless of lack of deficits when compared to those without OSA. digital.library.unt.edu/ark:/67531/metadc11049/
Math literacy: The relationship of algebra, gender, ethnicity, socioeconomic status, and AVID enrollment with high school math course completion and college readiness.
The questions guiding this research seek to discover the factors that affect high school math course completion and college readiness in a Texas suburban public school district. The first research question examines the relationship between 8th grade completion of Algebra I and high school mathematics course taking patterns and college readiness. The second question evaluates the relationship between race, gender, socioeconomic status and enrollment in the Advancement Via Individual Determination (AVID) program to college math readiness and high school mathematics course completion. Participants included 841 high school graduates of the class of 2006; 76% of the graduates were White, 15% Hispanic and 7% African American. Twenty-three percent of students were economically disadvantaged and 46% of students completed Algebra I in 8th grade. Chi-square, Cramer's V, and multiple regression were conducted to evaluate possible relationships between variables. The Chi-square and Cramer's V showed statistically significant (p<.05) relationships between 8th grade algebra completion and both college readiness and high school math course completion. A significant statistical relationship was also found between college readiness and each of the independent variables, ethnicity, economic status, completion of 8th grade algebra and enrollment in AVID. The number of math courses completed in high school was statistically related to ethnicity and economic status.. The findings of this study indicate that early access to Algebra I can positively affect the number of high school math courses a student completes and the likelihood that the student will be college ready after high school graduation. digital.library.unt.edu/ark:/67531/metadc11046/
Missionary Millennium: The American West; North and West Africa in the Christian Imagination
During the 1890s in the United States, Midwestern YMCA missionaries challenged the nexus of power between Northeastern Protestant denominations, industrialists, politicians, and the Association's International Committee. Under Kansas YMCA secretary George Fisher, this movement shook the Northeastern alliance's underpinnings, eventually establishing the Gospel Missionary Union. The YMCA and the GMU mutually defined foreign and domestic missionary work discursively. Whereas Fisher's pre-millennial movement promoted world conversion generally, the YMCA primarily reached out to college students in the United States and abroad. Moreover, the GMU challenged social and gender roles among Moroccan Berbers. Fisher's movements have not been historically analyzed since 1975. Missionary Millennium is a reanalysis and critical reading of religious fictions about GMU missionaries, following the organization to its current incarnation as Avant Ministries. digital.library.unt.edu/ark:/67531/metadc11043/
Transforming the Predator: Representations of the Child Sexual Abuser in 21st Century American Visual Media
This thesis examines the ways American visual media -television and mainstream/independent cinema- has presented the narrative of child sexual abuse since the beginning of the 21st century. Due to the rise of the counterculture movement and the sexual revolution of the 1960s, a discourse for talking about child sexuality was created. By providing an opportunity to discuss children and sex, for the first time cultural products could deal overtly with child sexual abuse, rather than connotatively. In response to this new discourse, conservative ideals about child sexuality proliferated in the 1970s and 1980s that attempted to return the child to a world of purity and asexuality with all threats to this purity being monstrous. The examples discussed in this thesis highlight the ways that contemporary American visual media has responded to three decades of obsession that created a "master narrative" of child sexual abuse - something that continues to play a significant role in society. digital.library.unt.edu/ark:/67531/metadc11031/
The Rise and Fall of a Revolutionary Relationship: George Washington and Thomas Paine, 1776-1796
This study is a cultural and political analysis of the emergence and deterioration of the relationship between George Washington and Thomas Paine. It is informed by modern studies in Atlantic history and culture. It presents the falling out of the two Founding Fathers as a reflection of two competing political cultures, as well as a function of the class aspirations of Washington and Paine. It chronologically examines the two men's interaction with one another from the early days of the American Revolution to the Reign of Terror of the French Revolution. Along the way this study highlights the dynamics that characterized the Washington-Paine relationship and shows how the two men worked together to further their own agendas. This study also points to Thomas Paine's involvement with a web of Democratic Societies in America and to Washington's increasing wariness and suspicion of these Societies as agents of insurrection. digital.library.unt.edu/ark:/67531/metadc11037/
Leader Emergence and Effectiveness in Virtual Workgroups: Dispositional and Social Identity Perspectives
In today's global competitive environment, many organizations utilize virtual workgroups to overcome geographic and organizational boundaries. Research into their dynamics has received the attention of scholars within multiple disciplines, and the potential for an integrative approach to the study of virtual workgroups exists. This dissertation is a first step towards such an approach. The primary aim of this research is to examine antecedent and contextual factors that affect the emergence and effectiveness of leaders in virtual workgroups. To achieve this aim, an integrative model assembled from theory and empirical findings in leadership, management, social identity, and communications research is posited. Hypothesized relationships depicted in the model identify key dispositional and contextual variables linked to leader emergence, member behavior, and leader effectiveness within virtual workgroups. This study employed a nonexperimental research design, in which leader emergence and social identity manifest as naturally occurring phenomena. Data collection occurred via two web-based surveys administered at different points in time. Hypothesized relationships were tested utilizing correlational and hierarchical moderated multiple regression analyses. The findings of this dissertation suggest that traits, such as personality and cognitive ability, are not associated with leader emergence in virtual workgroups. In addition, the results indicate that the exhibition of relationship-oriented leader behaviors enhances group identity. In turn, identification is associated with increases in perceptions of leader effectiveness and decreases in counterproductive behavior exhibited by group members. This dissertation exposes an important limitation to the application of trait leadership theory. It also demonstrates the importance of relationship-oriented behavior and social identity in virtual contexts. Further, it advances an integrative theoretical model for the study of virtual workgroup phenomena. These contributions should assist and inform other researchers, as well as practitioners, interested in leadership and group member behavior in virtual workgroups. digital.library.unt.edu/ark:/67531/metadc11035/
Dementia, Diabetes, and Depression: Relationship to Cognitive Functioning
The number of adults in the United States who are age 65 or older is rapidly increasing. With longer lifespan comes an increase in chronic diseases such as dementia, diabetes, and depression. This study used archival data from a larger study conducted at the Memory Clinic at John Peter Smith County Hospital in Ft. Worth, Texas to examine several hypotheses and research questions related to the influence of type of dementia, presence of Type II diabetes, and presence of depression on neuropsychological test performance. First, this study attempted to identify specific patterns of performance on neuropsychological measures for those with Alzheimer's dementia (AD), vascular dementia (VaD), or mild cognitive impairment (MCI). The results indicated that those with MCI perform better than those with AD or VaD on all neuropsychological measures, and that those with VaD perform better than those with AD on a measure of verbal memory. Another purpose of the study was to determine how the presence of Type II diabetes affects this pattern of functioning; the overall finding in this study was that the presence or absence of diabetes did not affect performance on measures of cognitive functioning. Additionally, the study attempted to add to literature examining the influence of depression on older adults with diabetes and/or dementia; no significant differences emerged. digital.library.unt.edu/ark:/67531/metadc11032/
Predicting beginning master's level counselor effectiveness from personal characteristics and admissions data: An exploratory study.
In this exploratory study of 95 counseling program master's students at a large southwestern public university, students' scores on an admissions Group Interview Sociometric Rating did not correlate with their GRE Analytic Writing (GRE-AW) scores nor their basic skills course instructors' end-of-course assessment of students' counseling-related personality traits (Personality) or mastery of basic counseling skills (Mastery). However, Mastery was predicted by both Personality, with a large effect size, and GRE-AW, with a medium effect size. This study provides promising preliminary evidence that counselor educators may use Counselor Personality Assessment Ratings and GRE-AW scores to screen master's applicants by predicting students' abilities to master basic counseling skills early in their counselor preparation. Limitations of the study and recommendations for future research are discussed. digital.library.unt.edu/ark:/67531/metadc11038/
Performance appraisal impact on employee career development and performance: A longitudinal study.
Access: Use of this item is restricted to the UNT Community.
The purpose of this study was to determine the effectiveness of the implementation of an internally created performance appraisal system as well as the subjects' overall satisfaction with the implementation. The system was implemented at a major technology consulting firm in the US. The subjects of this study were three levels of employees of the firm. An employee survey conducted annually at the firm included questions relating to the implementation of the performance appraisal system. Eight years of employees' responses to three key questions were analyzed. Employees' perceptions of the appraisal feedback aiding increased performance, their belief about the implementation assisting with their career management, satisfaction with the initiative, and their understanding of the requirements for promotion were captured by this survey. Trend analysis indicates that employees at the firm perceived their career path knowledge unimproved, their understanding of promotion criteria unimproved as a result of the implementation. Employees did not indicate overall satisfaction with the implementation and the employee's belief about their skills and abilities utilization did not improve post implementation. digital.library.unt.edu/ark:/67531/metadc5420/
Computational Studies of Coordinatively Unsaturated Transition Metal Complexes
In this research the validity of various computational techniques has been determined and applied the appropriate techniques to investigate and propose a good catalytic system for C-H bond activation and functionalization. Methane being least reactive and major component of natural gas, its activation and conversion to functionalized products is of great scientific and economic interest in pure and applied chemistry. Thus C-H activation followed by C-C/C-X functionalization became crux of the synthesis. DFT (density functional theory) methods are well suited to determine the thermodynamic as well as kinetic factors of a reaction. The obtained results are helpful to industrial catalysis and experimental chemistry with additional information: since C-X (X = halogens) bond cleavage is important in many metal catalyzed organic syntheses, the results obtained in this research helps in determining the selectivity (kinetic or thermodynamic) advantage. When C-P bond activation is considered, results from chapter 3 indicated that C-X activation barrier is lower than C-H activation barrier. The results obtained from DFT calculations not only gave a good support to the experimental results and verified the experimentally demonstrated Ni-atom transfer mechanism from Ni=E (E = CH2, NH, PH) activating complex to ethylene to form three-membered ring products but also validated the application of late transition metal complexes in respective process. Results obtained supported the argument that increase in metal coordination and electronic spin state increases catalytic activity of FeIII-imido complexes. These results not only encouraged the fact that DFT and multi-layer ONIOM methods are good to determine geometry and thermodynamics of meta-stable chemical complexes, but also gave a great support to spectroscopic calculations like NMR and Mossbauer calculations. digital.library.unt.edu/ark:/67531/metadc5488/
The Online and the Onsite Holocaust Museum Exhibition as an Informational Resource
Museums today provide learning-rich experiences and quality informational resources through both physical and virtual environments. This study examined a Holocaust Museum traveling exhibition, Life in Shadows: Hidden Children and the Holocaust that was on display at the Art Center of Battle Creek, Michigan in fall 2005. The purpose of this mixed methods study was to assess the informational value of a Holocaust Museum exhibition in its onsite vs. online format by converging quantitative and qualitative data. Participants in the study included six eighth grade language arts classes who viewed various combinations or scenarios of the onsite and online Life in Shadows. Using student responses to questions in an online exhibition survey, an analysis of variance was performed to determine which scenario visit promotes the greatest content learning. Using student responses to additional questions on the same survey, data were analyzed qualitatively to discover the impact on students of each scenario visit. By means of an emotional empathy test, data were analyzed to determine differences among student response according to scenario visit. A principal finding of the study (supporting Falk and Dierking's contextual model of learning) was that the use of the online exhibition provided a source of prior orientation and functioned as an advanced organizer for students who subsequently viewed the onsite exhibition. Students who viewed the online exhibition received higher topic assessment scores. Students in each scenario visit gave positive exhibition feedback and evidence of emotional empathy. Further longitudinal studies in museum informatics and Holocaust education involving a more diverse population are needed. Of particular importance would be research focusing on using museum exhibitions and Web-based technology in a compelling manner so that students can continue to hear the words of survivors who themselves bear witness and give voice to silenced victims. When perpetuity of access to informational resources is assured, future generations will continue to be connected to the primary documents of history and cultural heritage. digital.library.unt.edu/ark:/67531/metadc5407/
Foucault's Foundationless Democratic Theory
I examine a key shift in Michel Foucault's political philosophy from a position in which he was a staunch anti-humanist, to a final position in which he advocated not only the ability of the subject to influence his political condition, but also the individual freedoms assured by a democratic form of government. I begin by summarizing his overall critique of the post-Enlightenment West, and then explain how his observation of the Iranian Revolution served as a key turning point concerning his attitude towards the subject. Next, I elaborate on the direction of Foucault's late writings and examine how his new conceptualization of the subject leads him to embrace a democratic political system albeit free from Enlightenment philosophical foundations. I conclude by critiquing Foucault's foundationless democratic theory on the basis that it would ultimately undermine the individual freedoms and aesthetic development that he seeks to protect. digital.library.unt.edu/ark:/67531/metadc5475/
Measurement and Utility of Functional Behavioral Assessments and Behavior Intervention Plans in Classrooms for Students with Emotional and Behavioral Disorders
This research study examined how education service providers conduct functional behavioral assessments and utilize behavior intervention plans to address the social and emotional needs of students with challenging behaviors. The data are based on a 20-item survey administered to educators who identified themselves as working with students diagnosed with emotional and behavioral disorders. The results and implications of the survey are discussed and evaluated to the review of literature conducted prior to the study. Recommendations for future research are also explored. digital.library.unt.edu/ark:/67531/metadc5469/
Timing and Congestion Driven Algorithms for FPGA Placement
Placement is one of the most important steps in physical design for VLSI circuits. For field programmable gate arrays (FPGAs), the placement step determines the location of each logic block. I present novel timing and congestion driven placement algorithms for FPGAs with minimal runtime overhead. By predicting the post-routing timing-critical edges and estimating congestion accurately, this algorithm is able to simultaneously reduce the critical path delay and the minimum number of routing tracks. The core of the algorithm consists of a criticality-history record of connection edges and a congestion map. This approach is applied to the 20 largest Microelectronics Center of North Carolina (MCNC) benchmark circuits. Experimental results show that compared with the state-of-the-art FPGA place and route package, the Versatile Place and Route (VPR) suite, this algorithm yields an average of 8.1% reduction (maximum 30.5%) in the critical path delay and 5% reduction in channel width. Meanwhile, the average runtime of the algorithm is only 2.3X as of VPR. digital.library.unt.edu/ark:/67531/metadc5423/
Descriptive Analysis of the Association for the Study of Higher Education Dissertation of the Year Award Winning Dissertation and Recipients, 1979 - 2004
Access: Use of this item is restricted to the UNT Community.
This mixed-methodology study examined a set of award winning dissertations to determine what factors may have led to their receiving recognition by the Association for the Study of Higher Education (ASHE). The study addressed seven specific research questions which were answered via two different research designs: 1) a survey administered to the 27 recipients of the dissertation award, and 2) through the qualitative assessment of a sample of the winning dissertations. The quantitative survey was distributed to recipients of the Association for the Study of Higher Education Dissertation of the Year award from 1979 through 2004. The survey collected specific information on the personal attributes and characteristics of the award recipients, descriptive information about the award winning dissertations, information concerning the quality of the winner's doctoral experiences, the quality of their relationship with their dissertations advisors and the progression of their careers after winning the award. The qualitative assessment involved applying a set of evaluative questions provided by Gall, Gall and Borg to describe a sample of the award winning documents. The results indicated that recipients of the ASHE award were not representative of education doctoral students as indicated by 2004 data. The results of the study also indicated that, as a group, these dissertations winners were full-time doctoral students, likely recipients of some form of financial assistance (assistantship and fellowships) and were able to complete their dissertations and degrees in substantially less time than typical education doctoral students. The findings also suggest that Gall, Gall and Borg's procedure for evaluating educational research can be used to assess doctoral dissertations. digital.library.unt.edu/ark:/67531/metadc5400/
A Tuscan Lawyer, His Farms and His Family: The Ledger of Andrea di Gherardo Casoli, 1387-1412
This is a study of a ledger written by Andrea di Gherardo Casoli between the years 1387 and 1412. Andrea was a lawyer in the Tuscan city of Arezzo, shortly after the city lost its sovereignty to the expanding Florentine state. While Andrea associated his identity with his legal practice, he engaged in many other, diverse enterprises, such as wine making, livestock commerce, and agricultural management. This thesis systematically examines each major facet of Andrea's life, with a detailed assessment of his involvement in rural commerce. Andrea's actions revolved around a central theme of maintaining and expanding the fortunes, both financial and social, of the Casoli family. digital.library.unt.edu/ark:/67531/metadc11041/
The Sacred and the Profane: Nin, Barnes, and the Aesthetics of Amorality
Barnes's Vagaries Malicieux, and Nin's Delta of Venus, are examples the developing vision of female sex, and both authors use their literary techniques to accomplish their aesthetic vision of amorality. Nin's visions are based on her and her friends' extreme experiences. Her primary concern was expressing her erotic and amorally aesthetic gaze, and the results of her efforts are found in her aesthetic vision of Paris and the amoral lifestyle. Barnes uses metaphor and linguistics to fashion her aesthetic vision. Her technique in "Run, Girls, Run!" both subverts any sense of morality, and offers an interesting and challenging read for its audience. In "Vagaries Malicieux" Barnes's Paris is dark while bright, and creates a sense of nothingness, indicated only by Barnes's aesthetic appreciation. digital.library.unt.edu/ark:/67531/metadc11047/
Correlates of Texas Standard AP Charter Campuses and How They Compare with Standard AP Traditional Public Campuses
The research sought to objectively evaluate the effectiveness of Texas standard AP open-enrollment charter school campuses and to discover independent variables that may be utilized to predict effective charter school campuses. The literature review was designed to enhance the current understanding of charter schools and therefore facilitate a more effective evaluation of them. A basic knowledge and understanding of the origins, characteristics and purposes of charters allow for a more objective analysis. The literature review covered the history of charters including their founders, characteristics, and growth patterns. The data items used in the analyses were downloaded from the 2007-2008 Academic Excellence Indicator System (AEIS), which contains a variety of data from all Texas public schools. Multiple statistical analyses were utilized including chi-square, ANOVA, multiple regression and discriminate analysis. In order to evaluate Texas standard AP open enrollment charter campuses, their accountability ratings were compared with those of standard AP traditional public school campuses. The research evaluated twelve independent variables for charter schools to determine their relationship to accountability ratings, thereby providing charter operators indicators or predictors of accountability ratings to facilitate better academic quality. By analyzing the same variables for traditional public schools as charter schools, a baseline model was developed to compare the similarities and differences with the results of the charter school analyses. digital.library.unt.edu/ark:/67531/metadc11042/
Always Painting the Future: Utopian Desire and the Women's Movement in Selected Works by United States Female Writers at the Turn of the Twentieth Century
This study explores six utopias by female authors written at the turn of the twentieth century: Mary Bradley Lane's Mizora (1881), Alice Ilgenfritz Jones and Ella Merchant's Unveiling Parallel (1893), Eloise O. Richberg's Reinstern (1900), Lena J. Fry's Other Worlds (1905), Charlotte Perkins Gilman's Herland (1915), and Martha Bensley Bruère's Mildred Carver, USA (1919). While the right to vote had become the central, most important point of the movement, women were concerned with many other issues affecting their lives. Positioned within the context of the late nineteenth century women's rights movement, this study examines these "sideline" concerns of the movement such as home and gender-determined spheres, motherhood, work, marriage, independence, and self-sufficiency and relates them to the transforming character of female identity at the time. The study focuses primarily on analyzing the expression of female historical desire through utopian genre and on explicating the contradictory nature of utopian production. digital.library.unt.edu/ark:/67531/metadc11060/
Characterizing Storm Water Runoff from Natural Gas Well Sites in Denton County, Texas
In order to better understand runoff characteristics from natural gas well sites in north central Texas, the City of Denton, with assistance through an EPA funded 104b3 Water Quality Cooperative Agreement, monitored storm water runoff from local natural gas well sites. Storm water runoff was found to contain high concentrations of total suspended solids (TSS). Observed TSS concentrations resulted in sediment loading rates that are similar to those observed from typical construction activities. Petroleum hydrocarbons, in contrast, were rarely detected in runoff samples. Heavy metals were detected in concentrations similar to those observed in typical urban runoff. However, the concentrations observed at the gas well sites were higher than those measured at nearby reference sites. Storm water runoff data collected from these sites were used to evaluate the effectiveness of the water erosion prediction project (WEPP) model for predicting runoff and sediment from these sites. Runoff and sediment predictions were adequate; however, rainfall simulation experiments were used to further characterize the portion of the site where drilling and extraction operations are performed, referred to as the "pad site." These experiments were used to develop specific pad site erosion parameters for the WEPP model. Finally, version 2 of the revised universal soil loss equation (RUSLE 2.0) was used to evaluate the efficiency of best management practices (BMPs) for natural gas well sites. BMP efficiency ratings, which ranged from 52 to 93%, were also evaluated in the context of site management goals and implementation cost, demonstrating a practical approach for managing soil loss and understanding the importance of selecting appropriate site-specific BMPs. digital.library.unt.edu/ark:/67531/metadc11064/
Correlates of a Past Behavior Interview for the Business Unit Leader: Experience, Motivation, Personality and Cognitive Ability
This research evaluates the relationship between various individual differences constructs and performance on a past behavior interview (PBI)-one of the most popular forms of personnel selection interviews used today-within a sample of business unit leader level incumbents and applicants from organizations across the United States. Correlation analysis is conducted on the relationship between overall performance on a PBI and four work-related constructs: Experience, Motivation, Personality, and Cognitive Ability. The existing literature on PBIs and the four independent variables is critically reviewed. As limited research has been conducted on the influence of Experience and Motivation on PBI performance, this study makes unique contributions to the literature regarding impact of these two constructs. The major hypotheses stated that Experience and Motivation would yield significant, positive correlations with PBI performance while Personality and Cognitive Ability would not be significantly correlated with PBIs. Results partially supported the hypotheses-Experience, Motivation, and Personality were significantly related to overall PBI score, while Cognitive Ability was not. Implications for the findings as well as suggestions for future research are discussed. digital.library.unt.edu/ark:/67531/metadc11066/
An investigation of factors affecting Omani faculty members' adoption of information and computing technology.
The purpose of this study was to explore the factors influencing information and computing technology (ICT) adoption for Omani faculty members from a framework of Rogers' theory of diffusion of innovation. Three hundred Omani faculty members from Sultan Qaboos University (SQU) participated in the study. The survey consisted of five parts: (a) an 18-item questionnaire on ICT uses and skills, (b) a 1-item questionnaire on adopter category, (c) a 44-item self-constructed questionnaire on perception of barriers to adopting ICT, (d) a 50-item questionnaire on ICT attributes adapted from Moore and Benbasat, and (e) a 15-item questionnaire on demographic and job-related variables. Descriptive statistics indicated that the faculty members overall used ICT at the "Sometimes" level and had ICT skills at the "Intermediate" level. The most frequently used and skillful ICT functional areas were Website browsing, Internet search engine, and word processing. One-way ANOVAs found significant group differences of ICT uses and skills, perception of barriers, and perception of ICT attributes in the category of adopter. Early adopters used ICT more, had higher ICT skills, perceived fewer barriers in the adopting process, and recognized higher values of ICT attributes than later adopters did. Multiple regression analysis showed the level of ICT uses could be predicted by ICT skills, adopter category, perception of barriers, ICT attributes, and the selected demographic and job-rated background variables, to a large magnitude with an adjusted R2 value of .70. The level of ICT skills was the most salient predictor. Perception of ICT attributes and the number of traditional classes taught appeared to be important as well. Results supported Rogers' theory at the macro level but not at the micro level. digital.library.unt.edu/ark:/67531/metadc11063/
The War for Peace: George H. W. Bush and Palestine, 1989-1992
The administration of President George H. W. Bush from 1989 to 1992 saw several firsts in both American foreign policy towards the Middle East, and in the Palestinian-Israeli conflict. At the beginning of the Bush Presidency, the intifada was raging in the West Bank and Gaza Strip, and by the time it was over negotiations were already in progress for the most comprehensive agreement brokered in the history of the conflict to that point, the Oslo Accords. This paper will serve two purposes. First, it will delineate the relationships between the players in the Middle East and President Bush during the first year of his presidency. It will also explore his foreign policy towards the Middle East, and argue that it was the efforts of George H. W. Bush, and his diplomatic team that enabled the signing of the historic agreement at Oslo. digital.library.unt.edu/ark:/67531/metadc11061/
Exploring Thai EFL University Students' Awareness of Their Knowledge, Use, and Control of Strategies in Reading and Writing
The purpose of this research was to conduct case studies to explore and describe Thai university students' awareness and application of cognitive and metacognitive strategies when reading and writing in English-as-a-foreign-language (EFL). Four participants, including two high and two low English language proficiency learners, were selected from 14 students enrolled in a five-week course called English for Social Sciences offered at Kasetsart University in Bangkok, Thailand in 2005. The major sources of data for the analyses included the transcripts of the participants' pair discussions, think-aloud protocols, interviews, and daily journal entries. In addition, field work observations, reading and writing strategy checklists, participants' written work, and the comparison of the pretest and posttest results were also instrumental to the analyses. The interpretive approach of content analysis was employed for these four case studies. Findings were initially derived from the single-case analyses, and then from cross-case analyses. Major findings revealed that strategic knowledge enhanced these English-as-a-foreign- language (EFL) learners' proficiency in English reading and writing. However, applying elaborative strategies for higher-level reading was challenging for most of the participants. Two crucial factors that impeded their development were the learners' uncertain procedural and conditional knowledge of strategy uses and their limited English language proficiency due to limited exposure to the second language (L2). The teacher's explanations and modeling of strategies, the participants' opportunities to discuss strategy use with peers, and extensive practice positively enhanced their development. Additionally, the learners' schema and knowledge of text structures played significant roles in their development of the two skills. These English-as-a-foreign-language (EFL) learners also developed metacognitive awareness and strategy applications, but not to the level that always enhanced effective regulation and control of their reading and writing behaviors. Combining reading and writing in English-as-a-foreign-language (EFL) instruction promoted the learners' awareness of the relationships of certain strategies for the two skills, and developed their literacy skills holistically. digital.library.unt.edu/ark:/67531/metadc5429/
The Effects of Labeling and Stigma on the Social Rejection of Striptease Performers
This study uses survey data collected from a convenience sample of undergraduate students (N=89). A vignette survey design is employed to measure social rejection of striptease performers compared to a control group. Data is also collected on negative stereotypes held about striptease performers, which are correlated with social rejection. Link and Phelan's conceptualization of the stigma process provides the theoretical framework for this analysis. Findings suggest that striptease performers experience higher levels of social rejection and are perceived more negatively than the control group and that endorsement of negative stereotypes is associated with social rejection. digital.library.unt.edu/ark:/67531/metadc5466/
An empirical investigation of manufacturing flexibility and organizational performance as moderated by strategic integration and organizational infrastructure.
The purpose of this study is empirically investigating four research questions related to manufacturing flexibility. 1) What are the components of manufacturing flexibility? 2) Is there a relationship between manufacturing flexibility and organizational performance? 3) Do integrated strategies strengthen the relationship between manufacturing flexibility and organizational performance? 4) Are there organizational characteristics that strengthen the relationship between manufacturing flexibility and organizational performance? This study used a cross-sectional survey design to collect data from manufacturing organizations in multiple industries. Organizational performance was quantified using common manufacturing measures. Strategic integration and organizational infrastructure were also measured. Data were collected using a self-administered questionnaire. Factor analysis, correlation analysis, and regression were used to analyze the data. The results indicate the variables and expected relationships exist as hypothesized. This study contributes to the manufacturing flexibility body of knowledge by identifying relationships between the manufacturing flexibility component, performance, strategic integration, and organizational infrastructure. The instrument development in this study is of particular value as there are few rigorously developed and validated instruments to measure the manufacturing flexibility components and performance. Understanding these relationships will help practitioners make better decisions in manufacturing organizations as well as enable application of the concepts in this study to other contexts such as service organizations. digital.library.unt.edu/ark:/67531/metadc11065/
Between the Waves: Truth-Telling, Feminism, and Silence in the Modernist Era Poetics of Laura Riding Jackson and Muriel Rukeyser
Access: Use of this item is restricted to the UNT Community.
This paper presents the lives and early feminist works of two modernist era poets, Laura Riding Jackson and Muriel Rukeyser. Despite differences of style, the two poets shared a common theme of essentialist feminism before its popularization by 1950s and 60s second wave feminists. The two poets also endured periods of poetic silence or self censorship which can be attributed to modernism, McCarthyism, and rising conservatism. Analysis of their poems helps to remedy their exclusion from the common canon. digital.library.unt.edu/ark:/67531/metadc5419/
It's a Different World: Gender Variations in the Satisfaction of African American College Students
The purpose of this research study was to explore gender variances in the satisfaction levels of African American students at UNT toward the goal of increasing the retention of these students. Variances in satisfaction levels were measured using information obtained from African American students that participated in the fall 2004 administration of the Noel Levitz Student Satisfaction Inventory (SSI). In addition, the UNT Customer Satisfaction Survey (UNT-CSS), which applies Hom's Basic Model of Customer Satisfaction, was used to further examine areas of interest identified by the Noel Levitz SSI. Analysis of the SSI data indicated that no statistical significance existed amongst any of the correlates of satisfaction as a function of gender. In fact, African American students appeared to have very similar ideas on what services were important to them and on how satisfied they were with the services provided to them by the university. African American males and females were most satisfied with Campus Support Services, Academic Advising/Counseling, and Instructional Effectiveness at UNT. The UNT-CSS further examined the above areas. African American males and females were measured against each other to discern if differences occur in how African American students process the customer service model as a function of gender. African American males demonstrated strong positive correlations between their expectation of customer service and their consequent evaluation of that service. African American females were more influenced by their perception of the service received. digital.library.unt.edu/ark:/67531/metadc5487/
The impact of child teacher relationship training on teachers' and aides' use of relationship-building skills and the effect on student classroom behavior.
This study examined the impact of child teacher relationship training (CTRT) on teachers' and aides' use of relationship- building skills in the classroom and the correlation between teachers' and aides' demonstration of relationship- building skills and the effect on student behavior. CTRT was modeled after Landreth and Bratton's (2006) 10-session filial therapy model titled child parent relationship therapy (CPRT) which is based on the principles and procedures of child -centered play therapy. The CPRT manual was adapted slightly for use with teachers and aides for this project. In this quasi-experimental design, 12 teacher aide dyads (n = 24) were assigned to the experimental (n = 12) or active control groups (n = 12). Children who scored in the Borderline/Clinical range on at least one scale of the Child Behavior Checklist-Caregiver/Teacher Report Form (C-TRF) at pretest qualified for the study (N = 32). During the first phase of treatment, teachers and aides participated in the equivalent of 10 training/supervision sessions consistent with the principles and procedures of CPRT. During CTRT Phase II, teachers and aides participated in 10 weeks of coaching/modeling to facilitate the use of CTRT skills in the classroom environment and continued to participate in weekly 1-hour group training/supervision sessions. Eight hypotheses were analyzed. Different analyses were conducted based on the hypotheses. Analyses of covariance and repeated measures analysis of variance were conducted. Correlation coefficients were also calculated. Additionally, effect sizes were calculated to determine practical significance. Two hypotheses were retained at the .05 level of significance. Children in the experimental group (n = 19) demonstrated a significant decrease (p = .04) in Externalizing Problems between Measurements 1 and 3 when compared to the children in the active control group (n = 13). A statistically significant relationship was found between teachers' and aides' higher use of relationship-building skills and students' decrease in externalizing behaviors (p < .05). No statistically significant results were found on the remaining hypotheses. digital.library.unt.edu/ark:/67531/metadc5457/
Beethoven's Opus 18 String Quartets: Selected First Movements in Consideration of the Formal Theories of Heinrich Koch as Expressed in Versuch Einer Anleitung Zur Composition
Heinrich Koch completed his treatise in 1793, a pioneering work regarding the musical phrase as well as a sonata form description (lacking that term). Composition of Opus 18 began in 1798, a momentous project for several reasons in Beethoven's early career. Here, the theories expressed in Koch's Versuch are taken as an analytic springboard into a thorough analysis of the first movement of the quartet published no. 3, which was the first composed; additionally, nos. 1 and 6 are explored to a lesser degree. This study in phrase-analysis demonstrates significance in the fundamental ideas of Koch as applied to a masterwork of the turn of the 19th century. digital.library.unt.edu/ark:/67531/metadc5427/
Knowledge Management and Law Enforcement: An Examination of Knowledge Management Strategies of the Police Information System (POLNET) in the Turkish National Police
This research study explores knowledge management (KM) in law enforcement, focusing on the POLNET system established by the Turkish National Police as a knowledge-sharing tool. This study employs a qualitative case study for exploratory and descriptive purposes. The qualitative data set came from semi-structured face-to-face and telephone interviews, as well as self-administered e-mail questionnaires. The sample was composed of police administrators who created POLNET, working under the Department of Information Technologies and the Department of Communication. A content analysis method is used to analyze the data. This study finds that law enforcement organizations' KM strategies have several differences from Handzic and Zhou's integrated KM model. Especially, organizational culture and structure of law enforcement agencies differently affect knowledge creation, conversion, retrieval, and sharing processes. Accordingly, this study offers a new model which is dynamic and suggests that outcomes always affect drivers. digital.library.unt.edu/ark:/67531/metadc11040/
Commercial Motor Vehicle Driver Safety: An Application of Ethics Theory
Safety is an important aspect of ethical, socially responsible logistics. Current U.S. motor carrier (MC) safety research topical coverage includes the effects of individual and environmental influences, carrier safety management, and regulatory compliance on carrier safety and driver fatigue/safety performance. Interestingly, little research on the subject of truck drivers' safety attitudes and behaviors exists and the underlying decision-making processes that guide drivers' safety-related behaviors have received little attention. Furthermore, researchers have not provided an integrated framework that explains individual, organizational, and regulatory factors' impact on drivers' safety decision-making and performance. Truck drivers' safety judgments, decisions, and actions must adhere to societal safety norms. To that end, ethical decision-making theory that draws from the deontological and teleological traditions in moral philosophy provides a theoretical foundation and integrated framework necessary to better understand drivers' safety decision-making processes. The current research sought to determine how drivers rely on safety norms and perceived consequences in forming safety judgments and behavioral intentions. Furthermore, the study was designed to explore how various factors (i.e., individual, organizational, and regulatory) influence drivers' safety decision-making processes. Specifically, the study sought to answer the broad question, "How do commercial motor vehicle drivers make safety-related decisions, and how do individual, organizational, and regulatory factors influence drivers' safety decision-making processes?" An experimental two-factor design (2×2) was used to manipulate safety norms (i.e., "deontologically unsafe situation" and "deontologically safe situation") and consequences (i.e., "positive consequences" and "negative consequences"). Multivariate statistical analysis revealed that drivers primarily rely on deontological evaluations in forming safety judgments. Furthermore, drivers primarily relied on safety judgments when forming behavioral intentions. Drivers' attitudes toward unsafe actions and the effectiveness of driver-related safety regulations were also influential to drivers' judgments and intentions, respectively. The empirical findings demonstrate to managers that communication and education of safety norms may be highly effective to improve safety in unique occupational contexts where employees are given high levels of responsibility with little physical supervision, and where judgment errors can have devastating consequences for multiple stakeholders. digital.library.unt.edu/ark:/67531/metadc11048/
Barriers Limiting Access to Hospice Care for Elderly African Americans in Amarillo, Texas
Access: Use of this item is restricted to the UNT Community.
This study examines barriers limiting access to hospice care for elderly African Americans. Ethnic background plays a critical role in the development of attitudes, beliefs and expectations related to death and issues surrounding hospice care. The purpose of this study was to identify barriers that may limit access to hospice care for African Americans. A questionnaire was administered to 56 elderly African Americans in three religious settings and an African American senior citizens center. The questionnaire was designed to obtain information concerning African Americans' attitudes toward death and dying; religious beliefs; health beliefs; familiarity with hospice and prospective use of hospice. The results of the study indicate a number of barriers in access to hospice care for African Americans including: hospice knowledge barriers; education/outreach barriers; cultural knowledge barriers related to death/dying values; family/social support barriers; hospice organizational/provider barriers; health care organizational/provider barriers; and reimbursement barriers. digital.library.unt.edu/ark:/67531/metadc2855/
Anne Brontë's New Women: Agnes Grey and The Tenant of Wildfell Hall as Precursors of New Woman Fiction
Access: Use of this item is restricted to the UNT Community.
Anne Brontë's Agnes Grey and The Tenant of Wildfell Hall were published more than forty years before the appearance of the feminist type that the Victorians called the “New Woman;” yet, both novels contain characteristics of New Woman fiction. By considering how Brontë's novels foreshadow New Woman fiction, the reader of these novels can re-enact the “gentlest” Brontë as an influential feminist whose ideology informed the construction of the radical New Woman. Brontë, like the New Woman writers, incorporated autobiographical dilemmas into her fiction. By using her own experiences as a governess, Brontë constructs Agnes Grey's incongruent social status and a morally corrupt gentry and aristocracy through her depiction of not only Agnes's second employers, the Murrays, but also the morally debauched world that Helen enters upon her marriage to Arthur Huntingdon in The Tenant of Wildfell Hall. Moreover, Brontë incorporates her observations of Branwell's alcoholism and her own religious beliefs into The Tenant of Wildfell Hall. Although Brontë's novels contain autobiographical material, her heroines are fictional constructions that she uses to engage her readers with the woman question. Brontë accomplishes this engagement through her heroines' narrative re-enactments of fictional autobiographical dilemmas. Helen's diary and Agnes's diary-based narrative produce the pattern of development of the Bildungsroman and foreshadow the New Woman novelists' Kunstlerromans. Brontë's heroines anticipate the female artist as the protagonist of the New Woman Kunstlerromans. Agnes and Helen both invade the masculine domain of economic motive and are feminists who profess gender definitions that conflict with dominant Victorian ideology. Agnes questions her own femininity by internalizing the governess's status incongruence, and Helen's femininity is questioned by those around her. The paradoxical position of both heroines anticipates the debate about the nature and function of art in which the New Woman writers engaged. Through her reconciliation of the aesthetic and the political, Brontë, like the New Woman novelists who will follow, explores the contradiction between art and activism. digital.library.unt.edu/ark:/67531/metadc2834/
Political Identity of First-Year College Students: An Analysis of Student Characteristics Using Cooperative Institutional Research Program (CIRP) Data
This quantitative study utilized secondary self-reported data from the 2008 administration of the Cooperative Institutional Research Program (CIRP) Freshman Survey from two Texas public universities to investigate the pre-college demographic, academic, attitude, behavioral, and familial factors that may relate to students' self-reported political identities. The study design was correlational regarding the relationship of the demographic, academic, attitude, behavioral, and familial independent variables to the dependent variable of the students' political identities. ANOVA main effects for the independent variables were calculated, and statistical significance required the p < .05 level. The statistically significant demographic factors were native English-speaking status; enrollment status; citizenship status; religious preference; and race. The statistically significant academic factor was intended major. The statistically significant attitude factors were opinions regarding social issues such as criminal rights; abortion rights; the death penalty; the legalization of marijuana; homosexual relationships and same-sex marriage; racial discrimination; income taxes; affirmative action; military spending and voluntary military service; gun control; the environment; national health care; immigration; personal success; political dissent; and free speech. Other statistically significant attitude factors related to personal goals of making artistic and scientific contributions; being politically influential and politically knowledgeable; raising a family; participating in environmental programs and community action programs; developing a life purpose; promoting racial understanding; and promoting cultural understanding. The statistically significant behavioral factors were the frequency with which students participated in activities such as attending religious services; smoking; feeling overwhelmed or depressed; playing a musical instrument; discussing politics; and being involved in political campaigns. Other statistically significant behavioral factors were the frequency with which students participated in critical thinking activities such as using logical arguments to support their opinions; seeking alternative solutions to problems; researching scientific articles; exploring topics of personal interest; and accepting mistakes. The statistically significant familial factors were the religious preferences of the students' fathers and mothers. The results can give insight into the political characteristics of the students with whom student affairs professionals work. They can be used to inform the planning and implementation of educational programs that aid in students' political identity development. digital.library.unt.edu/ark:/67531/metadc28457/
Virulence Factor Production in PyrE Mutants of Pseudomonas Aeruginosa
It has been shown previously in our lab that mutations in the pyrimidine pathway reduced the ability of Pseudomonas aeruginosa to produce virulence factors. Knockout mutations in pyrB, pyrC and pyrD genes of the pyrimidine pathway showed that virulence factor production was decreased. Pyoverdin, pyocyanin, hemolysin, iron chelation, motility, and adherence are all considered virulence factors. Here I further investigate the effects of mutations in the pyrimidine pathway by studying a pyrE mutant. I studied the effect of the pyrE mutation on the production of the above virulence factors. Just like the effect of pyrB, pyrC and pyrD mutations,the pyrE mutation also showed that the bacteria were deficient in producing virulence factors when compared to the wild type. The broader impact of this research would be the possibility of finding drugs that could treat patients infected with P. aeruginosa and possibly extend the lives of chronically infected patients with cystic fibrosis. digital.library.unt.edu/ark:/67531/metadc28458/
The Determinants and Consequences of Empathic Parenting: Testing an Expansion of Belsky's Model of Parenting Using SEM
An understanding of factors that enhance empathic parenting behaviors is of considerable importance to the study of child development and to the development of parenting interventions to promote child adjustment. Moreover, gaining a better understanding of the factors that predict empathic parenting with older children is of interest since most research examining parental empathy focuses on infants. These were the goals of the current study. Guided by Belsky's 1984 process model of the determinants of parenting that impact child development, an expanded model of the determinants of parenting is proposed that includes various parent, child, and contextual factors of influence. Using data from a community sample, a partial least squares path analysis approach was employed to test the model's strength in predicting empathically attuned parenting with children ages 5 to 10 years and, ultimately, the child's psychoemotional functioning. Results support the expanded model; however, a reduced model was found to be superior and revealed unique relationships between the determinants of parenting. Specifically, a parent's psychoemotional functioning and childrearing beliefs and attitudes were found to be critical to the parent's ability to engage in empathic parenting behaviors. Other parent factors such as the parent's developmental history of abuse, maladaptive personality traits, and age, along with contextual factors and child characteristics, were found to influence parenting only indirectly through their impact on the parent's level of psychoemotional distress or childrearing beliefs and attitudes. Ultimately, the current findings support Belsky's claim that parent factors are the strongest predictors of empathic parenting. Implications of these findings are many. The results highlight the importance of assessing a parent's childrearing beliefs and attitudes and level of distress in conjunction with characteristics of the child when a family comes in for treatment. Moreover, the results identify many points of intervention to stopping the cycle of abuse. digital.library.unt.edu/ark:/67531/metadc28454/
A Comparative Analysis of the 1915 and 1919 Versions of Symphony No. 5 in E-flat Major, op. 82 by Jean Sibelius
The initial composition of the Fifth Symphony in E-flat Major, Op. 82 was undertaken as a commission to celebrate the composer's fiftieth birthday. Unhappy with the initial efforts, two revisions were then performed; the first was in 1916 and the final revision in 1919. Despite the larger form of the work seeming to have been changed between the 1915 and 1919 versions, the smaller gestures of thematic expression in both versions remained similar. On the surface, it had appeared that the composer had eliminated a movement, changing the 1919 version into a three movement form. This view was not challenged by the composer at the time, and since the earlier versions had either been withdrawn or destroyed, there was no way to compare the original efforts to the final product until recently. In comparing the 1919 version to the original, a definite strong parallel can be seen between the two - despite the changes to form, rearrangement of melodic material, and the seemingly different number of movements. However, the parallel is enough that the 1915 version can be a guide to classifying the 1919 version, an act that has eluded many scholars since the 1920s. Most importantly, comparing the two versions shows that the 1919 version is not a three movement form at all; it is a four movement form that is obscured by the connection of the first and second movements by a thematic bridge that contains elements from both movements, but is not placed within either structure. digital.library.unt.edu/ark:/67531/metadc28459/
The Effects of Jackpots on Responding and Choice in Two Domestic Dogs
The current study investigated the impact of delivering a jackpot on response rate and response allocation in two domestic dogs. For the purpose of this research, a jackpot was defined as a one-time, within-session increase in the magnitude of reinforcement. Two experiments were conducted to investigate the effects of delivering a jackpot in both single-operant and concurrent schedule procedures. Experiment 1 investigated the impact of a one-time, within-session increase in the magnitude of reinforcement on response rate in a single-operant procedure. Results of Experiment 1 showed no clear change in response rate after the delivery of the jackpot. Experiment 2 investigated the impact of a one-time, within-session increase in the magnitude of reinforcement on response allocation in a concurrent schedule procedure. Results of Experiment 2 showed an increase in response allocation to the jackpotted contingency in both subjects. These results suggest that a jackpot, as defined here, has no effect in single-operant procedures while having an effect in concurrent schedule procedures. These effects are similar to those reported in the magnitude of reinforcement literature. digital.library.unt.edu/ark:/67531/metadc28456/
Maleic anhydride grafted polypropylene coatings on steel: Adhesion and wear.
Polymeric coatings are being used in a growing number of applications, contributing to protection against weather conditions and localized corrosion, reducing the friction and erosion wear on the substrate. In this study, various polypropylene (PP) coatings were applied onto steel substrates by compression molding. Chemical modification of PP has been performed to increase its adhesion to metallic surfaces by grafting of maleic anhydride (MAH) onto PP in the presence of dicumyl peroxide (DCP). Influence of different concentrations of MAH and DCP on the properties of resulting materials have been examined. The coated steel samples are characterized by scanning electron microscopy (SEM), shear adhesion testing, FTIR and tribometry. The coatings with 3 wt. % MAH have shown the maximum adhesion strength due to maximum amount of grafting. The wear rates increased with increasing the amount of MAH due to simultaneous increase in un-reacted MAH. digital.library.unt.edu/ark:/67531/metadc28452/
An Assessment of Undergraduate Course Syllabi in the Departments of English at Universities in Taiwan
This exploratory, qualitative research explored the extent that course syllabi in the Departments of English in 13 public and 9 private universities in Taiwan reflect the inclusion of syllabus components to promote learning as recommended in the literature in the United States. Research questions included: what components can be inferred from the literature in the U.S. for the recommended components of a course syllabus, for the components for a learning-centered syllabus, and for a model to analyze Bloom's cognitive level of learning? And when these are applied to analyze course syllabi in English courses, are syllabi in these universities congruent with the models? The research identified and analyzed 235 course syllabi from the core courses listed online at these universities. The findings indicated that these syllabi are highly congruent with the syllabus components template; 68% of the syllabi included seven or more of the ten components. Additionally, these syllabi reflect medium congruency with the learning-centered syllabus template. Verbs used in objectives and learning outcomes in different English courses indicate different levels of cognitive learning goals as identified by Bloom's cognitive domain. Additional findings indicate that there was no difference in inclusion of components based on where faculty earned their doctoral degree. This research assumed similarities between higher education in Taiwan and the U.S., conclusions indicate that the course syllabi in Departments of English in Taiwan are congruent with the models recommended in the literature in the U.S. digital.library.unt.edu/ark:/67531/metadc28451/
A Performer's Analysis of Dominick Argento's Miss Havisham's Wedding Night
Dominick Argento's Miss Havisham's Wedding Night is the least explored of his artistic output. A monodrama in one act for soprano, Miss Havisham's Wedding Night contains some of Argento's most beautiful and challenging music of his compositional output. The purpose of a detailed analysis of the structure and content of Argento's Miss Havisham's Wedding Night is to facilitate the solo vocal performer's interpretation. Argento's setting of Miss Havisham's Wedding Night is unique in that he musically translates the manic psychological state of the literary character. Argento structured the one act opera in such a manner that the music would illuminate the text and the audience might connect with the unstable psychological episodes and outbursts demonstrated by Miss Havisham. To that end, each section and phrase has its own psychological motivation, which in turn demands a varied musical and dramatic interpretation. Utilizing selected scenes from Miss Havisham's Wedding Night, the researcher will analyze Argento's musical manifestation of Dickens's literary work. This research will include an investigation into the manner in which Argento uses the shape of melody and the musical phrase along with the harmonic materials to enhance the text and dramatic content. The author will explore the musical nuances Argento incorporates in an effort to develop and portray Miss Havisham's psychological state. Through an analysis of the orchestral writing the author will show how Argento's aesthetic balance between the music and text represents the emotional and psychological implications of the monodrama. digital.library.unt.edu/ark:/67531/metadc28455/
Optimal design of Dutch auctions with discrete bid levels.
Access: Use of this item is restricted to the UNT Community.
The theory of auction has become an active research area spanning multiple disciplines such as economics, finance, marketing and management science. But a close examination of it reveals that most of the existing studies deal with ascending (i.e., English) auctions in which it is assumed that the bid increments are continuous. There is a clear lack of research on optimal descending (i.e., Dutch) auction design with discrete bid levels. This dissertation aims to fill this void by considering single-unit, open-bid, first price Dutch auctions in which the bid levels are restricted to a finite set of values, the number of bidders may be certain or uncertain, and a secret reserve price may be present or absent. These types of auctions are most attractive for selling products that are perishable (e.g., flowers) or whose value decreases with time (e.g., air flight seats and concert tickets) (Carare and Rothkopf, 2005). I began by conducting a comprehensive survey of the current literature to identify the key dimensions of an auction model. I then zeroed in on the particular combination of parameters that characterize the Dutch auctions of interest. As a significant departure from the traditional methods employed by applied economists and game theorists, a novel approach is taken by formulating the auctioning problem as a constrained mathematical program and applying standard nonlinear optimization techniques to solve it. In each of the basic Dutch auction model and its two extensions, interesting properties possessed by the optimal bid levels and the auctioneer's maximum expected revenue are uncovered. Numerical examples are provided to illustrate the major propositions where appropriate. The superiority of the optimal strategy recommended in this study over two commonly-used heuristic procedures for setting bid levels is also demonstrated both theoretically and empirically. Finally, economic as well as managerial implications of the findings reported in this dissertation research are discussed. digital.library.unt.edu/ark:/67531/metadc28450/

Identification of highly gifted 5- and 6-year-old children: Measures to predict academic achievement.
Access: Use of this item is restricted to the UNT Community.
Studies indicate the educational needs of highly gifted students are best met through accelerated learning. It is difficult to recognize very young children that are suited for an accelerated curriculum because younger students frequently lack school records or portfolios used to identify gifted students. This study examined the accuracy of cognitive ability and achievement tests in predicting academic achievement by the end of second grade, correlating test results and final grade averages collected from sixteen children ages five to six who entered a public school program for high-ability learners in kindergarten. A multiple regression analysis indicated the Wechsler Preschool and Primary Scale of Intelligence produced the highest mean IQ score and a strong correlation with reading achievement. The Wechsler Individual Achievement Test contributed in small part to the prediction of academic achievement. The Naglieri Nonverbal Ability Test and the Kaufman Brief Intelligence Test-Second Edition had negative correlations with final grade averages, indicating they are not predictors of academic achievement for these students. digital.library.unt.edu/ark:/67531/metadc28471/
An Analysis of Interrater Agreement Between the Motivation Assessment Scale (MAS), Questions About Behavioral Function (QABF), and Analog Assessment Outcomes
An analysis of interrater agreement across multiple respondents on anecdotal assessments was compared with experimental functional analysis outcomes for correspondence. Experiment 1 evaluated the agreement of multiple respondents on the function of problem behavior for 22 individuals across 42 target behaviors using the Motivation Assessment Scale (MAS) and the Questions About Behavioral Function (QABF). Results showed agreement on the primary maintaining consequence for 4 or 5 of the 5 respondents in 52% (22/42) of the individual's target behaviors with the MAS and 57% (24/42) with the QABF. Experiment 2 examined whether correspondence occurred between the anecdotal assessment results and experimental functional analysis (EFA) results for 7 individuals selected from Experiment 1. Correspondence between the QABF assessment and the EFA was found for 6 of 7 participants, and 4 of the 7 showed correspondence between the EFA and the MAS. This study showed that the QABF had higher correspondence with analog assessments than the MAS thus, supporting the previous findings of Paclawskyj et al. (2001). digital.library.unt.edu/ark:/67531/metadc28477/
Rail Transit and Its Influence on Land Use: A Dallas Case Study
Access: Use of this item is restricted to the UNT Community.
Mass transit investments continue to be utilized in many cities as means of dealing with various transportation issues. In Dallas Texas, light rail transit was developed with the hopes of encouraging compact and orderly growth. This research uses the DART system as a case study in examining transportation/land use relationships in Dallas. As such, this thesis reviews past research that examined transit systems impacts on urban areas, analyzes historical changes in land use pattern development around the existing twenty stations of the DART light rail starter system, and summarizes the progression of land use trends in the transit corridor as they relate to DART impacts. Results of this study suggest that DART's light rail system has been an effective tool used in achieving the transportation and land use goals for the region. Finally, recommendations are presented with respect to what can be expected for future light rail development in Dallas. digital.library.unt.edu/ark:/67531/metadc2847/
Daughters of the King and Founders of a Nation: Les Filles du Roi in New France
The late seventeenth century was a crucial era in establishing territorial claims on the North American continent. In order to strengthen France's hold on the Quebec colony, Louis XIV sent 770 women across the Atlantic at royal expense in order to populate New France. Since that time, these women known as the filles du roi, have often been reduced to a footnote in history books, or else mistakenly slandered as women of questionable morals. This work seeks to clearly identify the filles du roi through a study of their socioeconomic status, educational background, and various demographic factors, and compare the living conditions they had in France with those that awaited them in Canada. The aim of this undertaking is to better understand these pioneer women and their reasons for leaving France, as well as to identify the lasting contributions they made to French-Canadian culture and society. digital.library.unt.edu/ark:/67531/metadc28470/
Examining the Origins of Sociology: Continuities and Divergences Between Ibn Khaldun, Giambattista Vico, August Comte, Ludwig Gumplowicz, and Emile Durkheim
This thesis examines the extent to which Ibn Khaldun can legitimately be considered a founding father of sociology. To pursue this research, Khaldun's theoretical framework will be compared with four Western scholars: Auguste Comte, Emile Durkheim, Giambattista Vico, and Ludwig Gumplowicz. This paper begins with an Introduction (Chapter I), followed by a general overview of Khaldun's work (Chapter II). Next, Khaldun's work is compared to that of Auguste Comte (Chapter III), Emile Durkheim (Chapter IV), Ludwig Gumplowicz (Chapter V) and Giambattista Vico (Chapter VI). In each of these chapters, Khaldun is compared and contrasted to the other social theorist, illustrating their similarities and considering their differences. Finally, in Chapter VII, I put forth conclusions that consider the extent to which Khaldun can validly be considered a founding father of sociology. digital.library.unt.edu/ark:/67531/metadc28478/
