The First Days of Spring: An Analysis of the International Treatment of Homosexuality
In recent history, the rights of gay, lesbian, bisexual and transgendered (LGBT) persons have been in constant fluctuation. Many states criminalize homosexual behavior while other states legally recognize same-sex marriages and same-sex adoptions. There are also irregular patterns where LGBT interest groups form across the globe. With this research project, I begin to explain why these discrepancies in the treatment of homosexuality and the formation of LGBT interest groups occur. I develop a theory that the most obvious contrast across the globe occurs when analyzing the treatment of homosexuals in OECD member states versus non-OECD countries. OECD nations tend to see the gay community struggle for more advanced civil rights and government protections, while non-OECD states have to worry about fundamental human rights to life and liberty. I find that this specific dichotomization is what causes the irregular LGBT interest group formation pattern across the globe; non-OECD nations tend to have fewer LGBT interest groups than their OECD counterparts. When looking at why non-OECD nations and OECD nations suppress the rights of their gay citizens, I find that religion plays a critical role in the suppression of the gay community. In this analysis, I measure religion several different ways, including …

A Descriptive Analysis of the Critical Thinking Model in Texas Elementary Education
Contributions from elementary education to the practice and reality of critical thinking are rare, largely because attempts in basic education to elucidate a concept of critical thinking have a hard time breaking through the elusiveness and indeterminacy that characterize the history and reality of the concept. This situation is due to, and a consequence of, the difficulty of delimiting critical thinking from related fields, such as metacognition, higher-order-thinking, problem solving, informal logic, reasoning skills, and decision making, to name a few. Texas school authorities designed and put into practice a battery of tools to evaluate critical thinking through the assessment programs TAKS and STAAR, without taking a position regarding the indeterminacy problems of the content of critical thinking. The purpose of this study was to reconstruct the pieces of the critical thinking model imparted to Texas elementary school children since 1999 and continues today. The findings indicate that the critical thinking model implemented in Texas elementary schools is a particular version of a skills-only approach of critical thinking that follows the classical logical paradigm, consisting of two sets of complementary skills. This model acquaints students with the components and structure of five types of arguments while it fails to substantiate …

Intimate Partner Homicide Rates in Chicago, 1988 to 1992: a Modified General Strain Theory Approach
Using data from the Chicago Homicide Dataset for years 1988-1992 and the Chicago Community Area Demographics, multiple regression and mediation analysis are used to examine various community level factors’ impact on Intimate Partner Homicide (IPH) rates per Chicago community area. The relationship between the percentage of non-white and IPH rate per Chicago community area is significant and positive, but disappears once economic strain is taken into account, as well as when family disruption is included in the model. There is a weak, but positive relationship between population density and IPH rates, but neither economic strain nor family disruption mediates the relationship between population density and IPH rates. Economic deprivation is positively related to IPH rates, but economic strain and family disruption partially mediate the relationship between economic deprivation and IPH rates. Finally, the relationship between the percentage of males aged 30-59 and IPH rates per community area in Chicago is moderately negative, but this relationship disappears once economic strain is accounted for in the model. However, family disruption does not mediate the relationship between the percentage of males aged 30-59 and IPH rates. These results indicate that some structural covariates impact IPH rates and that some relationships are mediated by …

A Similar Approach with Different Results: the Use of Baroque Elements in Stravinsky’s Suite Italienne (1933), Shostakovich’s Violin Sonata in G Major, Op 134 (1968) and Schnittke’s Suite in the Old Style (1972)
Igor Stravinsky (1882-1971), Dmitri Shostakovich (1906-1975) and Alfred Schnittke (1934-1998) were three of the most important avant-garde Russian composers of the twentieth century. Even though their music shares a number of important traits, their work also reflects very individualized and distinct compositional styles. This study illustrates the similarities in their approach and the contrasting elements present in three selected pieces: Stravinsky´s Suite Italienne for Violin and Piano (1933), Shostakovich’s Violin Sonata in G Major, Op. 134 (1968), and Schnittke’s Suite in the Old Style for Violin and Piano (Harpsichord) (1972). The study disseminates Stravinsky, Shostakovich, and Schnittke’s musical influences in these works, focusing particularly in the use of baroque elements by tracing a number of important aspects from their backgrounds. In addition, a chronological outline of compositions containing baroque elements is provided. Finally, this research examines stylistic traits of the seventeenth and eighteenth centuries in the three selected compositions: Suite Italienne, Violin Sonata, Op. 134, and Suite in the Old Style.

Revisioning a Masterpiece: Jon Magnussen’s “Psalm”
In 2001, composer Jon Magnussen met the unusual challenge of unifying his new score for Psalm, an already-existing dance work from 1967, with the original artistic conceit of the choreographer, José Limón, who died in 1972. Limón was inspired directly by his reading of André Schwartz-Bart’s Holocaust novel, The Last of the Just, and had initially desired to use Stravinsky’s Symphony of Psalms as the score for the dance. Faced with cost-preclusive licensing fees for the Stravinksy, Limón engaged Eugene Lester to compose a score for Psalm. The Lester score, now lost, served the work for only a brief time, when the piece fell out of the repertory. When approached to create a new score for the extant dance work, Magnussen chose to draw his own influence from three works: the dance itself, Schwartz-Bart’s novel, and Stravinsky’s Symphony of Psalms. In addition, Limón Company Artistic Director Carla Maxwell served as Magnussen’s collaborator in reworking Psalm to resemble the work she believed Limón had desired all along. Magnussen’s influence from Stravinsky and Schwartz-Bart are revealed in the choices of text, the scored forces, and melodic ideas generated by the composer by mapping the names of significant Holocaust sites onto scalar patterns. …

Surface Modifications to Enhance the Wear Resistance and the Osseo-integration Properties of Biomedical Ti-alloy
The current study focuses on improving the wear resistance of femoral head component and enhancing the osseo-integration properties of femoral stem component of a hip implant made of a new generation low modulus alloy, Ti-35Nb-7Zr-5Ta or TNZT. Different techniques that were adopted to improve the wear resistance of low-modulus TNZT alloy included; (a) fabrication of graded TNZT-xB (x= 0, 1, 2 wt%) samples using LENS, (b) oxidation, and (c) LASER nitriding of TNZT. TNZT-1B and TNZT-O samples have shown improved wear resistance when tested against UHMWPE ball in SBF medium. A new class of bio-ceramic coatings based on calcium phosphate (CaP), was applied on the TNZT sample surface and was further laser processed with the objective of enhancing their osseo-integration properties. With optimized LASER parameters, TNZT-CaP samples have shown improved corrosion resistance, surface wettability and cellular response when compared to the base TNZT sample.

Contribution of Hurricane Ike Storm Surge Sedimentation to Long-term Aggradation of Coastal Marshes in Southeastern Texas and Southwestern Louisiana
Coastal marshes and wetlands are vital natural resources that offer habitats for plants and animals, serve as ecological filtration for soil and water pollutants, and act as protection for coastlines. Fishing, both commercial and sport, has a large economic impact in the study area – the Gulf Coast between Galveston Bay, TX and Oak Grove, LA. The objective of this research was to determine the contribution of Hurricane Ike storm surge sedimentation to long-term marsh aggradation in Texas and Louisiana coastal marshes. The research hypothesized that Hurricane Ike’s storm surge deposit would be equal to decades and possibly even a century’s worth of the average annual non-storm sedimentation. A quantitative field study was performed. The storm surge deposit was examined in a series of 15 transects covering approximately 180 km east of Hurricane Ike’s landfall. Nine of the 15 transects were re-surveyed a year after the initial measurement to assess preservation of the deposit. The results demonstrate that Hurricane Ike contributed between 10 to 135 years’ worth of sediment to coastal marshes along the coasts of Texas and Louisiana, and the sediment deposits have been preserved for over two years.

Innovation Teams: an Empirical Examination of the Relationship of Team Climate and Development Strategies in Consumer Packaged Goods Industries
Companies’ new primary source for sustainable revenue growth comes from creating new innovations, rather than from mergers and acquisitions. Companies are finding it difficult to align internal support for the innovative creativity of teams with standard operating procedures. This research aims to discover how innovative teams contribute to forming development strategies that CPG firms use to create new products. Dimensions of the Theory of Team Climate in Innovation (TTCI) offer insight on the dimensions of development strategy. Specifically, by integrating the theories, a proposed model identifies the innovation team’s impact on the firm’s development strategies. Such understanding has the potential to increase firm profits, lower innovation costs, increase innovation speed, and support innovation training. To empirically test this model, employees responsible for product development in the consumer packaged goods (CPG) industries were surveyed. Structural modeling techniques were used to analyze the data. Findings indicate support for using TTCI to explain the compressed development strategy. Theoretical contributions include: 1) extending TTCI and its associated measures into tangible products industries, 2) refining and adding to TTCI measures, 3) extending the development strategies theory into tangible products industries, and 4) adding to the measures for development strategy. Future research appears fertile for methods …

Site Formation Processes and Bone Preservation Along the Trinity River Basin, North Central Texas
This thesis presents the results of geoarchaeological investigations of several archaeological sites along the Elm Fork of the Trinity River in north central Texas. Archaeological data recorded from mitigation excavations in Denton and Cooke counties were analyzed to understand the geologic impacts on faunal preservation resulting from site formation processes. The faunal assemblages are highly fragmented, even in settings known for good preservation. A combined approach using geoarchaeological and taphonomic techniques was implemented to examine how fragmentation, evidence of soil weathering, and differential preservation were impacted by differing geologic conditions throughout the river basin. Intrasite and intersite results of the sites show that a great deal of variability of faunal preservation is present at difference scales of analysis.

The Effects of Adlerian Play Therapy on Maladaptive Perfectionism and Anxiety and in Children
I used singlecase A-B-A experimental design to examine the effectiveness of Adlerian play therapy (AdPT) for children identified with clinical levels of perfectionism on the Conners Parent Rating Scale-Revised and Conners Teacher Rating Scale-Revised. Participants were 2 children, a 10 year-old Hispanic male and a 7 year-old Caucasian female. To examine the effect of AdPT on maladaptive perfectionism and anxiety, the Child-Adolescent Perfectionism Scale and the Revised Children’s Manifest Anxiety Scale were administered to the children twice weekly over 3 phases of the study: baseline (6 administrations), intervention (12-16 administrations), and maintenance (6 administrations) for a total of 24 to 29 data points. Additionally, parents and teachers completed the Conners Rating Scales-Revised5 times: (1) prior to study, (2) following baseline/prior to treatment, (3) midpoint of treatment, (4) following treatment, and (5) following maintenance phase.During the intervention phase, the male and female participants attended 21 and 16 play therapy sessions, their mothers attended 6 and 5 parent consultations, and their teachers attended 6 and 3 teacher consultations, respectively. Analysis of the child self-report assessments indicated mixed and inconclusive results regarding the effects of AdPT on target behaviors. However, results of the parent and teacher reports indicated clinically significant reductionsin maladaptive perfectionism …

Developing a Collection Digitization Workflow for the Elm Fork Natural Heritage Museum
Natural history collections house immense amounts of data, but the majority of data is only accessible by locating the collection label, which is usually attached to the physical specimen. This method of data retrieval is time consuming and can be very damaging to fragile specimens. Digitizing the collections is the one way to reduce the time and potential damage related to finding the collection objects. The Elm Fork Natural Heritage Museum is a natural history museum located at the University of North Texas and contains collections of both vertebrate and invertebrate taxa, as well as plants. This project designed a collection digitization workflow for Elm Fork by working through digitizing the Benjamin B. Harris Herbarium. The collection was cataloged in Specify 6, a database program designed for natural history collection management. By working through one of the museum’s collections, the project was able to identify and address challenges related to digitizing the museum’s holdings in order to create robust workflows. The project also produced a series of documents explaining common processes in Specify and a data management plan.

Mental Toughness Training for Police Officers: the Impact of a Stress Inoculation Program on Police Stress
This study examined the impact that a stress inoculation training (SIT) program had on a small-sized city police department in the southwestern U.S. Specifically, the aim of this study was to investigate how a SIT program impacted police officer self-reported levels of organizational stress, operational stress, perceived life stress, and mood states. All 24 participants were recruited from a population of 132 sworn, active duty police officers and were pre-tested through administration of a questionnaire packet containing a host of measures related to demographics, organizational stressors, operational stressors, general life stressors, and mood states. Participants were then randomly assigned to one of the following treatment conditions: (1) delayed training; (2) SIT program; and (3) SIT plus booster program. On completion of the SIT program, members of each of the treatment conditions were re-assessed through the administration of the aforementioned questionnaire packet. Subsequent to conducting the booster sessions, participants from each treatment condition took part in a second, and final, follow-up assessment. Results suggested that organizational stress was decreased for participants in the SIT program, particularly at follow-up. Results also suggested that energy (i.e., vigor) was increased for participants in the SIT plus booster program at both post-test and follow-up. Furthermore, …

Dislocation Dynamics Simulations of Plasticity in Cu Thin Films
Strong size effects in plastic deformation of thin films have been experimentally observed, indicating non-traditional deformation mechanisms. These observations require improved understanding of the behavior of dislocation in small size materials, as they are the primary plastic deformation carrier. Dislocation dynamics (DD) is a computational method that is capable of directly simulating the motion and interaction of dislocations in crystalline materials. This provides a convenient approach to study micro plasticity in thin films. While two-dimensional dislocation dynamics simulation in thin film proved that the size effect fits Hall-Petch equation very well, there are issues related to three-dimensional size effects. In this work, three-dimensional dislocation dynamics simulations are used to study model cooper thin film deformation. Grain boundary is modeled as impenetrable obstacle to dislocation motion in this work. Both tension and cyclic loadings are applied and a wide range of size and geometry of thin films are studied. The results not only compare well with experimentally observed size effects on thin film strength, but also provide many details on dislocation processes in thin films, which could greatly help formulate new mechanisms of dislocation-based plasticity.

The Power of One Reinforcer
Animal trainers use shaping to teach many behaviors. However, during shaping, the organism may engage in behaviors other than the target behavior or approximations to the target behavior. If the animal is engaged in other behaviors, the rate of reinforcement may decrease and the trainer may resort to what is sometimes referred to as a “desperation click.” That is, the trainer delivers one reinforcer for a behavior that is not a successive approximation to the target response. Anecdotal reports from trainers suggest that sometimes the animal continues to repeat this other behavior that received only one reinforcer, even in the absence of further reinforcement for that behavior. This study compared whether, during a one minute extinction period, participants spent more time engaged in a behavior that had been reinforced only once after a brief period of no reinforcement or in a behavior that had been reinforced multiple times. Participants, who were university students, played a tabletop game that involved touching and manipulating small objects. Five conditions were repeated twice for each participant: reinforcement for interacting with a training object alone, reinforcement for interacting with a training object with other objects present, reinforcement for interacting with a target object, one reinforcer …

Personality Factors and Trust in Placebo Medical Trials
Prior research has reported that individual differences influence both placebo and nocebo responses. The present study examined how individual personality, as well as trust, influence placebo/nocebo belief and symptom reporting after receiving an inert capsule that for some was described as an active “cognitively-enhancing” trial medication. Individuals (N = 104) were randomly assigned to one of three conditions: condition A participants were told they’d received the medication, condition B participants were told they’d received a placebo, and condition C participants were told, via random assignment, each would receive either the medication or placebo (after the experiment this condition listed the group – medication or placebo - each believed s/he was in). The study was completed in the UNT Student Health and Wellness Center to provide context in a medical setting. Of the 104 participants, 46 (44.2%) were either placed by experimental design or self-report in the medication group. Participants with a belief in medication ingestion, regardless of condition (i.e., A or C), reported significantly more symptoms (M = 16.65, SD = 3.178), than participants who believed they had ingested a placebo (M = 14.21, SD = 2.58), t (102) = 4.32, p = .001.

The Effect of Season Performance on Male and Female Track and Field Athletes’ Self-identity
Although the “self” has generally been conceptualized as relatively stable in sport-specific research, events such as deselection, injury, and career termination have been found to negatively affect athletes’ levels of identification with the athlete role. Additionally, there has been limited research regarding competitive failure and its ability to negatively affect athletes’ levels of identification with the athlete role. The purpose of the present investigation was to provide additional evidence regarding the influence poor competitive seasons have on the malleability of athletes’ self-identity. Athletes were followed throughout the course of their season to determine whether athletes who encountered a poor competitive season reported lowered levels of athletic identity. Specifically, male and female NCAA Division I track and field athletes completed pre-indoor, post-indoor, and post-outdoor assessments of athletic identity. Contrary to previous research, the current study’s results indicated no identifiable relationship between male and female athletes’ season performance satisfaction and their level of post-indoor and post-outdoor athletic identity. Thus, the greatest predictor of athletes’ post-season level of athletic identity was their pre-season level of athletic identity, regardless of season performance. Given these results, future research should assess self-esteem as well as other potential coping strategies athletes might use in order to gain …

Iron Sharpens Iron: Duets for Two Women in the Teaching/instruction of Undergraduate Women
Duet literature remains largely untapped as a pedagogical tool in the undergraduate voice studio. This dissertation examines the ways in which eight duets for female voices, although not written primarily for pedagogical use, may be used to teach four main areas of voice technique: intonation, vocal agility, legato singing, and dramatic skills. Duets are chosen primarily from the standard repertoire and are in English, German, French, Italian and Latin. The compositional styles range from the Baroque period through the 20th century. Genres include art song, oratorio, and opera. Each chapter focuses on one of the four vocal skills listed above, and includes examinations of two duets whose vocal writing (rhythm, tessitura, intervals, tempi, and text) make them appropriate candidates for pedagogical use in the improvement of that specific skill. Both male and female teachers of singing may utilize this project as a practical resource and model in how to use other duets, including those for other voice types, for similar purposes in their teaching studio. This project also demonstrates how the experience of singing duets helps students develop ensemble singing as they listen and respond to each other. Finally, this project offers voice teachers an additional pedagogical tool to help …

Organizational Justice Perception and Its Effects on Knowledge Sharing: a Case Study of Forensics in the Turkish National Police
In today’s economy, organizational knowledge is a fundamental factor for remaining competitive and managing intellectual capital. Knowledge Management aims to improve organizational performance by designing the work environment with necessary tools. Yet, significant amount of knowledge resides within the people in different forms such as experience or abilities. Transferring individual knowledge within members or into organizational repositories is so difficult. Knowledge sharing only occurs under certain circumstances: People share knowledge when they believe it is beneficial for them, when they feel safe and secure, and when they trust. Since knowledge is power, and brings respect to its bearer, knowledge sharing needs suitable environment. In this context, this study investigates intention to knowledge sharing among forensics in the Turkish National Police (TNP) and the factors -such as perceived organizational justice, organizational citizenship behaviors, subjective norms, and attitudes toward knowledge sharing- affecting their intentions. The researcher utilized a model developed from Ajzen and Fishbein’s (1975; 1980) theory of reasoned action (TRA). To test this model, a self-administered questionnaire survey was administered in Turkey In order to analyze the quantitative data; SPSS version 19 was used for all preliminary analyses and LISREL 8.8 was used for Regression Analysis and Path Analysis The fit …

The Effect of Head Flexion/extension on Acoustic Measures of Singing Voice Quality
A study was undertaken to identify the effect of head flexion/extension on singing voice quality. The amplitude of the fundamental frequency (F0), and the singing power ratio (SPR), an indirect measure of singer’s formant activity, were measured. F0 and SPR scores at four experimental head positions were compared with the subjects’ scores at their habitual positions. Three vowels and three pitch levels were tested. F0 amplitudes and low frequency partials in general were greater with more extended head positions, while SPR increased with neck flexion. No effect of pitch or vowel was found. Gains in SPR appear to be the result of damping low frequency partials rather than amplifying those in the singer’s formant region. Raising the amplitude of F0 is an important resonance tool for female voices in the high range, and may be of benefit to other voice types in resonance, loudness, and laryngeal function.

Doctoral Level Counseling Students’ Experiences and Perceptions of Learning in a Cohort Environment
Learning community literature supports the use of student cohorts to enhance learning through increased peer interaction and common course work. Researchers employed the qualitative method of phenomenography to identify various ways doctoral counseling students conceptualize and experience learning in a cohort over the course of a single academic year. Participants were all 10 members of a single southwestern U.S. university counseling program doctoral cohort of full-time students between 20 and 59 years of age with 5 members 20-29, 4 members 30-39, 1 member 50-59; 8 female, 2 male; 9 White non-Hispanic, 1 African-American. Data were transcripts from 30 one-hour interviews, three for each participant over the course of their first year of study. The research team that analyzed the data consisted of three advanced counseling program doctoral students, each with research methods coursework. Results revealed nine dynamic structural aspects of learning: dialogue, diversity, knowledge, motivation, support, shared experience, relationship development, interpersonal awareness, and conflict. Findings support the use of learning communities in doctoral level counselor education programs. Cohort members demonstrated increasing awareness of the potential learning benefits of cohort interaction and developed more in depth strategies over time to utilize the cohort to enhance learning. Future counselor educators may now …

Micro-images, Genera and Poème Exotique: a Guide to Tone Color Selection, Relative Dynamics and Temporal Pacing for Effective Performances of Three Microtonal Flute Works by Daniel Kessner
Micro-Images for Solo Flute, Genera for Flute/Alto Flute/Bass Flute and Clarinet/Bass Clarinet, and Poème exotique for Flute and Piano by American composer Daniel Kessner (b. 1946) utilize a hybrid compositional approach in which microtones are incorporated with more traditional chromatic writing. Through representative musical examples from each piece, this document highlights the timbral, dynamic and pacing complexities associated with the microtonal fingerings and prompts flutists to forgo idiosyncratic tendencies in favor of contextually based choices. In order to help guide musicians toward effective performances of these three pieces and similar works, a new tone color spectrum and description of relative dynamics are provided along with a discussion of the relationships between tone colors, relative dynamics and temporal pacing. Appendices include transcripts of email interviews with composer Daniel Kessner and Carla Rees, British contemporary flutist, as well as an updated list of Kessner’s flute works.

Exploring the Impact on Self-regulated Learning: a Comparative Analysis of Learner Experiences Using Problem-based Learning, Game Play, and Computer-based Instruction
The ability to transfer what you know to new and different contexts is a sign of successful learning. While students often graduate from college with the required number of courses many lack the skills necessary to apply appropriate strategies to solve problems in different contexts, to reason, and think critically. More than a decade ago the Boyer Report (1995) pointed to this fact as a sign that Universities were falling short in adequately supporting their undergraduate populations. As a result, it is not uncommon to see educational institutions introducing new courses and programs geared towards helping students learn better. This study explores learner experiences and the impact on self-regulated learning within a distributed learning setting when motivated by problem-based learning, game play, and computer-based instruction. In this study the instructional design of the course introduced undergraduate students to authentic learning experiences in which students engaged in collaborative problem solving and learning activities framed within the narrative of an alternate reality game. Fifteen self-regulated learning constructs were examined. The comparison group engaged with problem solving tasks and computer-based instruction. Additionally, the study used the theory Learning and Teaching as Communicative Action and its four communicative actions as a lens to understand …

Qos Aware Service Oriented Architecture
Service-oriented architecture enables web services to operate in a loosely-coupled setting and provides an environment for dynamic discovery and use of services over a network using standards such as WSDL, SOAP, and UDDI. Web service has both functional and non-functional characteristics. This thesis work proposes to add QoS descriptions (non-functional properties) to WSDL and compose various services to form a business process. This composition of web services also considers QoS properties along with functional properties and the composed services can again be published as a new Web Service and can be part of any other composition using Composed WSDL.
