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.

Since 2004, the number of people living with HIV (PLWH) has steadily increased by about 5% and currently, the number in Texas is about 86,000. Though the National HIV/AIDS Strategic Plan seeks to ensure “unfettered access to quality healthcare”, barriers to access still exist especially among minority populations. This study examines the relationship between HIV infection rates and the geographic location of HIV service centers with a focus on 4 counties: namely, Dallas, Denton, Harris and Tarrant. The goal is to show whether there is a spatial mismatch between HIV rates and service providers. Are service facilities located in zip codes where they are most needed? Using the vulnerability framework and the Inverse Care Law (ICL), we address the research question using demographic variables (race/ethnicity, sex, poverty, education attainment) and HIV data. Our results show that extreme vulnerable zip codes have high HIV rates and closest proximity to HIV service providers.

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 …

Social media offers numerous opportunities to companies, organizations and government agencies to communicate with people outside their organization, to promote their interests and to better serve their customers, or as in the case with government agencies, to better serve their citizens. However, little is known about how police departments in particular use social media. This research study explores why police departments use social media, how they manage their social media tools, and the problems and challenges experienced as they use social media. This qualitative study is largely guided by grounded theory. The data were collected from a study population using local police departments in the Dallas-Fort worth (DFW) area principal cities using both individual interviews with police departments’ social media officers and observations of these departments’ online social media tools (in particular, Facebook and Twitter). This study has shown that the DFW area city police departments are using social media quite extensively to keep the public informed and often for investigative purposes. There are some success factors to adopting and using these tools, such as the motivation of department staff and their benefits, successful implementation of the tools, the simplicity of using tools and that it is absolutely free.

In recent years there has been growing interest in limitless realism in computer graphics applications. Among those, my foremost concentration falls into the complex physical simulations and modeling with diverse applications for the gaming industry. Different simulations have been virtually successful by replicating the details of physical process. As a result, some were strong enough to lure the user into believable virtual worlds that could destroy any sense of attendance. In this research, I focus on fire simulations and its deformation process towards various virtual objects. In most game engines model loading takes place at the beginning of the game or when the game is transitioning between levels. Game models are stored in large data structures. Since changing or adjusting a large data structure while the game is proceeding may adversely affect the performance of the game. Therefore, developers may choose to avoid procedural simulations to save resources and avoid interruptions on performance. I introduce a process to implement a real-time model deformation while maintaining performance. It is a challenging task to achieve high quality simulation while utilizing minimum resources to represent multiple events in timely manner. Especially in video games, this overwhelming criterion would be robust enough to sustain …

Extracting meaningful information from large collections of text data is problematic because of the sheer size of the database. However, automated analytic methods capable of processing such data have emerged. These methods, collectively called text mining first began to appear in 1988. A number of additional text mining methods quickly developed in independent research silos with each based on unique mathematical algorithms. How good each of these methods are at analyzing text is unclear. Method development typically evolves from some research silo centric requirement with the success of the method measured by a custom requirement-based metric. Results of the new method are then compared to another method that was similarly developed. The proposed research introduces an experimentally designed testing method to text mining that eliminates research silo bias and simultaneously evaluates methods from all of the major context-region text mining method families. The proposed research method follows a random block factorial design with two treatments consisting of three and five levels (RBF-35) with repeated measures. Contribution of the research is threefold. First, the users perceived a difference in the effectiveness of the various methods. Second, while still not clear, there are characteristics with in the text collection that affect the …

The present research seeks to characterization of an additively manufactured and heat-treated Ti-xMn gradient alloy, a binary system that has largely been unexplored. In order to rapidly assess this binary system, compositionally graded Ti-xMn (0<x<15 wt%) specimens were fabricated using the LENS (Laser Engineered Net Shaping) and were subsequently heat-treated and characterized using a wide range of techniques. Microstructural changes with respect to the change in thermal treatments, hardness and chemical composition were observed and will be presented. These include assessments of both continuous cooling, leading to observations of both equilibrium and metastable phases, including the titanium martensites, and to direct aging studies looking for composition regimes that produce highly refined alpha precipitates – a subject of great interest given recent understandings of non-classical nucleation and growth mechanisms. The samples were characterized using SEM, EDS, TEM, and XRD and the properties probed using a Vickers Microhardness tester.

One in seven people in the world use online social networking for a variety of purposes -- to keep in touch with friends and family, to share special occasions, to broadcast announcements, and more. The majority of society has been bought into this new era of communication technology, which allows everyone on the internet to share information with friends. Since social networking has rapidly become a main form of communication, holes in privacy have become apparent. It has come to the point that the whole concept of sharing information requires restructuring. No longer are online social networks simply technology available for a niche market; they are in use by all of society. Thus it is important to not forget that a sense of privacy is inherent as an evolutionary by-product of social intelligence. In any context of society, privacy needs to be a part of the system in order to help users protect themselves from others. This dissertation attempts to address the lack of privacy management in online social networks by designing models which understand the social science behind how we form social groups and share information with each other. Social relationship strength was modeled using activity patterns, vocabulary usage, …

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 …

Magnesium alloys exhibit desirable properties for use in transportation technology. In particular, the low density and high specific strength of these alloys is of interest to the aerospace community. However, the concerns of flammability and susceptibility to corrosion have limited the use of magnesium alloys within the aircraft cabin. This work studies a magnesium alloy containing rare earth elements designed to increase resistance to ignition while lowering rate of corrosion. The microstructure of the alloy was documented using scanning electron microscopy. Specimens underwent salt spray testing and the corrosion products were examined using energy dispersive spectroscopy.

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. Aspects of Neuroticism and Extroversion, as …

Schools are increasingly challenged to respond to educational initiatives, implement accountability measures, and incorporate standards-driven curriculum changes introduced by laws such as the Individuals with Disabilities Education Improvement Act (IDEIA) of 2004. IDEIA signified a shift in the field of education and intensified practitioners’ concerns about the identification and instruction of students with learning disabilities (LD). The revisions to IDEIA proposed alternative models for the evaluation and identification of students with LD, such as response to intervention (RTI). RTI is an educational framework that supports students at-risk for academic failure by focusing on preventative measures. As teachers’ roles evolve in response to innovations such as RTI, teacher preparation programs must adjust their focus and curriculum accordingly. A parallel mixed-methods design was used to explore 100 general education pre-service teachers’ levels of concern regarding the implementation of RTI based on the concerns based adoption model. The sample for the study integrated general education pre-service teachers enrolled in professional development schools (PDS) at two levels of candidacy, PDS1 and PDS2. Data collected was analyzed utilizing canonical correlation analysis (CCA), multivariate analysis of variance (MANOVA), descriptive statistics, and thematic analysis. Results explain general education pre-service teachers’ levels of knowledge had a negative relationship …

The purpose of this study was to examine special education populations, special education reading achievement, and regular education reading achievement in relation to the implementation of the Reading First three-tiered model as a response to Intervention platform. The population for this study focused on rural schools with Grades K-3 in attendance. Schools participated in the reading first grant period of the 2003-2009 school years. Forty-seven Texas Reading First schools were compared to 47 campuses having similar populations, socioeconomic makeups, and grade structures. This study utilized quantitative research measures to evaluate the level of special education populations on Reading First campuses using a response to intervention model. Quantitative measures were also used to evaluate those same campuses achievement rates of both special education and regular education students on the Texas Assessment of Knowledge and Skills reading tests. The study's outcome data showed little to no statistic significance for the three research questions. However, the inferential statistics showed a decrease in the special education population of the Reading First schools. Inferential statistics also indicated both the special education and the regular education students showed growth on the Texas Assessment of Knowledge and Skills reading tests. The use of a response to intervention …

Metastable b-Ti alloys are titanium alloys with sufficient b stabilizer alloying additions such that it's possible to retain single b phase at room temperature. These alloys are of great advantage compared to a/b alloys since they are easily cold rolled, strip produced and can attain excellent mechanical properties upon age hardening. Beta 21S, a relatively new b titanium alloy in addition to these general advantages is known to possess excellent oxidation and corrosion resistance at elevated temperatures. A homogeneous distribution of fine sized a precipitates in the parent b matrix is known to provide good combination of strength, ductility and fracture toughness. The current work focuses on a study of different mechanisms to engineer homogeneously distributed fine sized a precipitates in the b matrix. The precipitation of metastable phases upon low temperature aging and their influence on a precipitation is studied in detail. The precipitation sequence on direct aging above the w solvus temperature is also assessed. The structural and compositional evolution of precipitate phase is determined using multiple characterization tools. The possibility of occurrence of other non-classical precipitation mechanisms that do not require heterogeneous nucleation sites are also analyzed. Lastly, the influence of interstitial element, oxygen on a precipitation …

Arvo Pärt's Concerto Piccolo über B-A-C-H for trumpet, strings, harpsichord, and piano is a brief yet challenging work in the trumpet repertoire. A carefully articulated performance guide is necessary to aid trumpeters in overcoming the numerous musical challenges presented in this piece.

This first section of this document provides historical and contextual information on Arvo Pärt, his compositional output during his experimental period, and subsequently, Concerto Piccolo. The second section includes a performance analysis of the work, while the third gives trumpet players pedagogical suggestions and practical exercises for proper preparation of Concerto Piccolo. This guide presents performers with relevant background, analytical, and pedagogical information required for an informed and high-level performance.

In 2012, the CIA World Fact Book showed that the service sector contributed about 76.6% and 51.4% of the 2010 gross national product of both the United States and Ghana, respectively. Research in the services area shows that a firm's success in today's competitive business environment is dependent upon its ability to deliver superior service quality. However, these studies have yet to address factors that influence customers to remain committed to a mass service in economically diverse countries. In addition, there is little research on established service quality measures pertaining to the mass service domain. This dissertation applies Rusbult's investment model of relationship commitment and examines its psychological impact on the commitment level of a customer towards a service in two economically diverse countries. In addition, service quality is conceptualized as a hierarchical construct in the mass service (banking) and specific dimensions are developed on which customers assess their quality evaluations. Using, PLS path modeling, a structural equation modeling approach to data analysis, service quality as a hierarchical third-order construct was found to have three primary dimensions and six sub-dimensions. The results also established that a country's national economy has a moderating effect on the relationship between service quality and …

This document also features a performance guide for the trumpet parts of The Silk House Tattoo. Pedagogical methods for learning the most challenging passages are evaluated, and daily exercises based on the specific demands of each excerpt are offered.

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 …

Ultimate is the fastest growing field sport in America. Created in 1968, forty-five years later the sport was still on the periphery of the mainstream but reached new heights in 2013 – two professional leagues, over 800 college teams and a broadcasting deal with ESPN – and the discussions throughout the sports’ history have never been as relevant. Self-officiation and the Spirit of the Game are the main tenets that make up the ethos of the sport and its community. These unique aspects differentiate Ultimate’s predominate culture from that of mainstream sports culture. This study shows the countercultural ties and survival of the ethos during the adolescent period of Ultimate’s evolution (1987-2010). It examines the progression of the community’s established grassroots culture and the governing body of the sport alongside the influx of young players with mainstream sports attitudes who bolstered certain organizers’ attempts to alter Ultimate in the hopes of gaining “legitimacy” through adding third-party officials, commercialization and corporate sponsorship.

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. …
