Religious Coping and Experience of Body Satisfaction Among College Women
This study examined whether religious coping moderated the effects of thin-ideal images on body satisfaction among college women. Religious (N = 178) participants met for a pre-test to complete religiosity measures. A week later, the participants reconvened and were assigned to one of two conditions: before (n = 83) or after (n = 95). Within each of these two groups, participants were randomly assigned to read a list of statements: positive religious statements, positive nonreligious statements, negative religious statements, positive body neutral religious statements, and neutral statements. Each participant was exposed to a task that included 10 images of thin-ideal models, read her list of statements, and completed the Body Dissatisfaction Scale of the EDI-3. The results revealed no significant main effect of placement, type of statement and no significant Placement X Statement Type interaction. However, when religious statements were collapsed and a subsequent 2 (Placement) X 3 (Statement type) analysis was conducted the results indicated a significant main effect for type of statement. Reading religious statements resulted in less body dissatisfaction than non-religious statements. There was no main effect for placement and no Placement X Statement Type interaction. Ethnic differences in religiosity were noted (all p’s <.05). Implications and …

The Art-Union and Photography, 1839-1854: The First Fifteen Years of Critical Engagement between Two Cultural Icons of Nineteenth-Century Britain
This study analyzes how the Art-Union, a British journal interested only in the fine arts, approached photography between 1839 and 1854. It is informed by Karl Marx’s materialism-informed commodity fetishism, Gerry Beegan’s conception of knowingness, Benedict Anderson’s imagined community, and an art critical discourse that was defined by Roger de Piles and Joshua Reynolds. The individual chapters are each sites in which to examine these multiple theoretical approaches to the journal’s and photography’s association in separate, yet sometimes overlapping, periods. One particular focus of this study concerns the method through which the journal viewed photography—as an artistic or scientific enterprise. A second important focus of this study is the commodification of both the journal and photography in Britain. Also, it determines how the journal’s critical engagement with photography fits into the structure and development of a nineteenth-century British social collectivity focused on art and the photographic enterprise.

Chronic Insomnia and Healthcare Utilization in Young Adults
Chronic insomnia is a highly prevalent disorder in general and young adult populations, and contributes a significant economic burden on society. Previous studies have shown healthcare utilization (HCU) is significantly higher for people with insomnia than people without insomnia. One limitation with previous research is accurate measurement of HCU in people with insomnia is difficult due to a high co-morbidity of medical and mental health problems as well as varying operational definitions of insomnia. Assessing HCU in people with insomnia can be improved by applying research diagnostic criteria (RDC) for insomnia, using a population with low rates of co-morbid medical/mental health problems, and measuring HCU with subjective, objective, and predictive methods. The current study found young adults with chronic insomnia had greater HCU than normal sleepers, specifically on number of medications, and chronic disease score (CDS) estimates of total healthcare costs, outpatient costs, and predicted number of primary care visits. The presence of a medical and/or mental health problem acted as a moderating variable between chronic insomnia and HCU. Simple effects testing found young adults with chronic insomnia and a medical/mental health problem had the greatest HCU followed by normal sleepers with a medical/mental health problem, chronic insomnia, and normal …

A Real-Time Electronic Sound Analysis System with Graphical User Interface
Noise-induced hearing loss is a serious problem common to musical environments. Current dosimetry technology is primarily designed for industrial environments and not suited for musical settings. At present, there are no government regulations that apply to the educational music environment as it relates to monitoring and prevention of hearing loss. Also, no system exists than can serve as a proactive tool in observation and reporting of sound exposure levels with the goal of hearing conservation. Newly proposed system takes a software based approach in designing a proactive dosimetry system that can assess the risk of sound noise exposure. It provides real-time feedback trough a graphical user interface that is capable of database storage for further study.

Re-Envisioning an Eighteenth-Century Artifact: A Postmodern Reading of Tristram Shandy
The interjection of a new and dynamically different reading of Lawrence Sterne’s Tristram Shandy is imperative, if scholars want to clearly see many of the hidden facets of the novel that have gone unexamined because of out-dated scholarship. Ian Watt’s assumption that Sterne “would probably have been the supreme figure among eighteenth-century novelists” (291) if he had not tried to be so odd, and the conclusion that he draws, that “Tristram Shandy is not so much a novel as a parody of a novel” (291), is incorrect. Throughout the thesis, I argue that Sterne was not burlesquing other novelists, but instead, was engaging with themes that are now being examined by postmodern theories of Jacques Derrida, Michel Foucault, and Jean François Lyotard: themes like the impenetrability of identity (“Don’t puzzle me” (TS 7.33.633)), the insufficiency of language (“Well might Locke write a chapter upon the imperfections of words” (5.6.429)), and the unavailability of permanence (“Time wastes too fast” (9.8.754)). I actively engage with their theories to deconstruct unexamined themes inside Tristram Shandy, and illuminate postmodern elements inside the novel. However, I do not argue that Tristram Shandy is postmodern. Instead, I argue that if the reader examines the novel outside …

Factors Affecting Police Officers' Acceptance of GIS Technologies: A study of the Turkish National Police
The situations and problems that police officers face are more complex in today’s society, due in part to the increase of technology and growing complexity of globalization. Accordingly, to solve these problems and deal with the complexities, law enforcement organizations develop and apply new techniques and methods such as geographic information systems (GIS). However, the successful implementation of a new technology does not just depend on providing perfect technical support, but effective and active interaction between the user and system. For this reason, research examining user acceptance of GIS technologies provides a valuable source to investors and designers to predict whether the results of the technology will meet user expectations; understanding the factors that influence user acceptance is vitally important to make the system more usable and preferable. This study attempts to explain Turkish National Police officers’ beliefs about and behaviors toward GIS applications by using the technology acceptance models. It contributes to the technology acceptance literature by testing the proposed model in a rarely studied organization: law enforcement. Regarding methodology, I distributed a survey questionnaire in Turkey; the unit of analysis was the law enforcement officers in the Turkish National Police (TNP). In order to analyze the data derived …

Anticipating Work and Family: Experience, Conflict, and Planning in the Transition to Adulthood
The purpose of this study was to examine the development of work and family plans in young adults, and to clarify the long-term stability, prevalence, and consequences of anticipated work-family conflict. The study utilizes Super’s model of career development and social cognitive career theory, as well as research on current work-family interface, as a framework for understanding the period of anticipating and planning for multiple role integration that occurs between adolescence and adulthood. A sample of 48 male and 52 female college students assessed two years prior completed self-report questionnaires measuring work, marriage, and parenting experience; anticipated work-family conflict; and multiple-role planning. Results of this study suggest that students desire both a career and a family, and recognize potential challenges of a multiple-role lifestyle. Such recognition of anticipated work-family conflict varies by conflict domains and measurement methods, but remains stable over two years. Results also suggest that anticipated work-family conflict does not mediate the relationship between experience and planning; instead, marriage experience predicts planning directly. Implications for the findings are discussed as are suggestions for directions of new research concerning anticipated work-family conflict and planning for multiple roles.

Evaluating the Effects of Public Postings on Energy Conservation Behavior at a Public University
This study evaluated the effects of public postings on energy conservation behavior at a public university, using a multiple baseline design across three settings; bathrooms break rooms, and conference rooms. The behavior of building occupants was recorded to assess the frequency at which those individuals would turn lights off upon exiting an unoccupied room. The independent variables implemented by experimenters (light-switch plate stickers and laminated signs) had little to no effects on cumulative instances of lights turned off however, the installation of motion sensor lights produced better results. Across all conditions, lights were turned off most frequently in conference rooms (65% of observations) followed by break rooms (9% of observations), and bathrooms (3% of observations).

Effects of a Play-Based Teacher Consultation (PBTC) Program on Interpersonal Skills of Elementary School Teachers in the Classroom
The purpose of this study was to examine the effectiveness of a play-based teacher consultation (PBTC) program on individual teachers’ interpersonal classroom behaviors and teacher-child relationships. The research questions addressed the application of child-centered play therapy principles and PBTC increasing teacher responsiveness, decreasing teacher criticism, and enhancing teachers‟ perceptions of the teacher-child relationship in elementary school classrooms. Single-case design was utilized to examine eight teachers‟ perceptions over 16 weeks. The sample included 8 White female teachers from three local elementary schools. Teacher ages ranged from 28 to 59 years old. There were 5 kindergarten, 1 first grade, and 2 second grade teachers. The teachers participated in one educational training session followed by play sessions with children of focus and interactive modeling sessions. Trained observers, blind to the study’s purpose, utilized the Interaction Analysis System in classroom observations of the teachers, three times per week, to examine teachers’ interpersonal skills. Additionally, the teachers completed the Student Teacher Relationship Scale for the children of focus before and after the play session phase to examine change in the teacher-child relationship. Visual analysis of the data indicated the PBTC’s overall positive impact. 5 out of 8 teachers demonstrated increases in teacher responding scores at …

The Influence of Classroom Community and Self-Directed Learning Readiness on Community College Student Successful Course Completion in Online Courses
The relationships between community college students’ sense of community, student self-directed learning readiness, and successful completion of online courses were investigated using a correlational research design. Rovai’s Classroom Community Scale was used to measure classroom community, and the Fisher Self-directed Learning Readiness Scale was used to measure self-directed learning readiness, including three subscales of self-management, desire for learning, and self-control. The study participants were 205 students (49 males, 156 females; 131 White, 39 Black, 15 Asian, 10 Latino, 10 Multi-racial, 1 Native American) taking online courses during a summer term at a Texas community college. The research hypotheses were tested using Pearson r correlation coefficients between each of the seven independent variables (student learning, connectedness, classroom community, self-management, desire for learning, self-control, and self-directed learning readiness) and student successful course completion data. Contrary to prior study results, no association was found between students’ sense of community in online courses and student successful course completion. Although statistically significant differences were found between successful course completion and self-management (r = .258), desire for learning (r = .162), and self-directed learning readiness (r = .184), effect sizes were small suggesting a lack of practical significance. Possible reasons for the outcome of this study …

Resilience and Health Outcomes in Patients with Traumatic Injury
Due to the increasing healthcare costs and reduced length of hospital stay it is becoming increasingly important to identify individuals who are ‘at risk’ of experiencing long-term health issues. The purpose of the study was to: (1) determine if resilience, self efficacy and depression changed from inpatient to 3-month follow up; (2) examine the relationship between resilience, self efficacy, depression, and quality of life (social roles/activity limitations) at inpatient and 3-month follow up; and (3) identify if resilience at inpatient is related to change scores in selfefficacy and depression at 3-month follow up. Results from the paired sample t-test indicated that participants did not experience a significant change from inpatient to 3-month follow up in resilience or self-efficacy, but a significant decrease in depression was observed. Findings also indicated significant correlations between resilience, self-efficacy, and depression during inpatient stay and resilience, self-efficacy, depression, and quality of life at 3-month follow up. However, there was no relationship found between resilience and change scores in self-efficacy and depression. Future resilience research should continue to identify the variables that are most strongly related to resilience so effective interventions can be developed that improve rehabilitation outcomes, decrease secondary and chronic conditions as well as …

User-Centered Evaluation of the Quality of Blogs
Blogs serve multiple purposes, resulting in several types of blogs that vary greatly in terms of quality and content. It is important to evaluate the quality of blogs, which requires appropriate evaluation criteria. Unfortunately, there are minimal studies on framework and the specific criteria and indicators for evaluating the quality of blogs. Moreover, quality is related to user perception, and should therefore be evaluated by the receivers. This dissertation examines the criteria and indicators that blog users consider important for evaluating the quality of blogs, and develops a user-centered framework for evaluating quality by conducting user surveys and post-survey email interviews. The personal characteristics that affect the users’ choices of criteria to evaluate the quality of blogs are examined as well. The study’s findings include 1) the criteria that users consider important when evaluating the quality of blogs are content quality, usability, authority, and blog credibility; 2) the indicators that blog users consider most important for evaluating the quality of blogs are understandability, accuracy, believability, currency, ease of use, and navigation; and 3) gender, education level, age, profession, purpose of use, and specific interests affect the user’s choices of criteria for evaluating the quality of blogs. Future research may involve …

Reconsidering Regionalism: The Environmental Ethics of Sarah Orne Jewett, Kate Chopin, and Willa Cather
This study identifies environmentalist themes in the fiction and nonfiction of Sarah Orne Jewett, Kate Chopin, and Willa Cather and argues that these ideals are interdependent upon the authors’ humanistic objectives. Focusing on these three authors’ overlapping interest in topics such as women’s rights, environmental health, and Native American history, this dissertation calls attention to the presence of a frequently unexplored but distinct, traceable feminist environmental ethic in American women’s regional writing. This set of beliefs involves a critique of the threats posed by a patriarchal society to both the environment and its human inhabitants, particularly the women, and thus can be classified as proto-ecofeminist. Moreover, the authors’ shared emphasis on the benefits of local environmental knowledge and stewardship demonstrates vital characteristics of the bioregionalist perspective, a modern form of environmental activism that promotes sustainability at a local level and mutually beneficial relationships among human and nonhuman inhabitants of a naturally defined region. Thus, the study ultimately defines a particular form of women’s literary activism that emerged in the last decades of the nineteenth century and argues for these authors’ continued theoretical relevance to a twenty-first-century audience increasingly invested in understanding and resolving a global environmental predicament.

Testing the Impacts of Social Disorganization and Parochial Control on Public Order Crimes in Turkey
The primary focus of this study is to investigate the effects of social control mechanisms on public order crimes in Turkey. Supporting efforts of parochial control is a rising trend in crime control activities. Statements regarding the relationship between social disorganization variables, parochial control variables, and spatial distribution of crime have long been studied by researchers. Using the same assumptions in this study, I test their applicability to public order crimes in Turkey. The poverty and residential mobility variables had significant positive effect on public order crimes holding other structural and parochial variables constant. The number of public order crimes seems to be higher in provinces where there are more disrupted families. The number of public order crimes seems to be lower in provinces where there are more religious institutions. Overall, the results reveal that social structural variables and parochial control factors affect the institutional bases of provinces and partly affect the occurrence of public order crimes. Based on the study findings, several policy implications and recommendations for future research are suggested.

Modeling Place Vulnerability of HIV/AIDS in Texas
This study provides a measurable model of the concept of place vulnerability for HIV/AIDS that incorporates both community and structural level effects using data provided at the ZIP code level from the Texas Department of State Health Services. Sociological literature on the effects of place on health has been growing but falls short of providing an operational definition of the effects of place on health. This dissertation looks to the literature in medical/health geography to supplement sociology’s understanding of the effects of place on health, to the end of providing a measurable model. Prior research that has recognized the complexity of the effects of place still have forced data into one scale and emphasized individual-level outcomes. A multilevel model allows for keeping the associated spatial unit data, without aggregating or parsing it out for convenience of model fit. The place vulnerability model proposed examines how exposure, capacity and potentiality variables all influence an area’s HIV/AIDS count. To capture the effects of place vulnerability at multiple levels, this dissertation research uses a multilevel zero-inflated poisson (MLZIP) model to examine how factors measured at the ZIP code and county both affect HIV/AIDS counts per ZIP code as an outcome. Furthermore, empirical Bayes …

Measuring Semantic Relatedness Using Salient Encyclopedic Concepts
While pragmatics, through its integration of situational awareness and real world relevant knowledge, offers a high level of analysis that is suitable for real interpretation of natural dialogue, semantics, on the other end, represents a lower yet more tractable and affordable linguistic level of analysis using current technologies. Generally, the understanding of semantic meaning in literature has revolved around the famous quote ``You shall know a word by the company it keeps''. In this thesis we investigate the role of context constituents in decoding the semantic meaning of the engulfing context; specifically we probe the role of salient concepts, defined as content-bearing expressions which afford encyclopedic definitions, as a suitable source of semantic clues to an unambiguous interpretation of context. Furthermore, we integrate this world knowledge in building a new and robust unsupervised semantic model and apply it to entail semantic relatedness between textual pairs, whether they are words, sentences or paragraphs. Moreover, we explore the abstraction of semantics across languages and utilize our findings into building a novel multi-lingual semantic relatedness model exploiting information acquired from various languages. We demonstrate the effectiveness and the superiority of our mono-lingual and multi-lingual models through a comprehensive set of evaluations on specialized …

NNS Use of Adverbs in Academic Writing
Recent studies have begun to redefine the idea of accuracy in second language acquisition to include not only grammatical correctness, but also native-like selection. This is an exploratory study aimed at identifying areas of nonnative-like selection of adverbs, such as sentence position, semantic category preferences, frequency of use and breadth of word choice. Using corpus-linguistic methods it compares the writing of nonnative English speakers at an intermediate and advanced level to both American college students’ writing and published academic writing. It also conducts in-depth case studies of three of the most commonly used adverbs. It finds that while advanced students are grammatically accurate, there are still several ways in which their use of adverbs differs from that of native speakers.

Race Differences in Religiosity, Social Support, and Quality of Life among People Living with HIV/AIDS in Dallas/ Ft. Worth, TX
This study examines race differences and the relationship between religiosity/ spirituality and social support on quality of life (QOL) among people living with HIV/AIDS in Dallas/Ft. Worth, TX. The data were obtained from the Project VOICES research study conducted by the Center of Psychosocial Health Research at University of North Texas in 2003. This study explores the hypotheses that religiosity/spirituality and social support positively influences quality of life among people living with HIV/AIDS. The current study uses a diverse, gender-balanced sample consisting of African Americans (n = 156), aged 20-68, 47% male, 52% female and 1% transgendered) and Non-African Americans (n = 131), aged 19-65, 50% male, 46% female and 3% transgendered) (Caucasian, Latino, & others) to evaluate the relationship among variables of interest. Multiple regression analyses revealed that social support was a significant factor explaining quality of life (QOL) for African Americans when controlling for medical variables but did not for non-African Americans. Religiosity/spirituality was not found to be significant in this study. The implications of the findings are discussed.

The Effects of Capturing and Searching on the Acquisition of a Simple Arm Position
The present experiment compared two methods of training a simple arm position using auditory feedback: capture and search. The participants were four right-handed female college students. During capture, auditory feedback was delivered by the experimenter after the participant moved along a single axis into the target position. During search, auditory feedback was produced by the computer after the participant left clicked a mouse inside the target location. The results of a multi-element design showed that participants performed more accurately during capture training than search training. Pre-training and post-training probes, during which no auditory feedback was provided, showed similar fluctuations in accuracy across probe types. A retention check, performed seven days after the final training session, showed higher accuracy scores for search than capture, across all four participants. These findings suggest that TAGteach should incorporate an approach similar to search training to improve training outcomes.

Faunal Exploitation during the Depopulation of the Mesa Verde Region (A. D. 1300): A Case Study of Goodman Point Pueblo (5MT604)
This analysis of faunal remains from Goodman Point Pueblo (5MT604), a large village occupied just before the ancestral Puebloans permanently left southwestern Colorado at the end of the thirteenth century, explores the effect of dietary stress during abandonment in the Four Corners region. As archaeologists, we interpret what these former cultures were like and what resources they used through what they left behind. By specifically looking at faunal remains, or remains from food resources, environmental change and dietary stress can be assessed. Identifications of taxa identified at Goodman Point are made explicit via a systematic paleontology. This is followed by site-level taxonomic abundances and spatial analysis. Then, effects of technological innovations, environmental change, and sample quality are examined as alternate explanations of shifts in foraging efficiency, particularly related to animal hunting. Analyzing why and if the availability of faunal resources changes over time helps to clarify why the ancestral Puebloans left southwestern Colorado.

A Comparison of Principals’ Perceptions of Preparedness Based on Leadership Development Opportunities
This research study identified the frequency in which six public school districts in Texas provided principals with effective development opportunities prior to the principalship excluding university or certification programs. A purposive sample of over 200 principals from six school districts in the Dallas/Fort Worth area were asked to participate in the study yielding a response rate of 41%. Respondents identified through a questionnaire their leadership development opportunities and perceptions of preparedness on nine standards common to the profession. Principals were nominally grouped for comparison. The perceptions of preparedness for principals who received effective leadership development opportunities were compared to those who did not receive these same opportunities using an independent samples t-test to determine statistical significance (p < .05). Peer coaching yielded the most statistically significant results in three standards. This finding indicates principals who receive peer coaching prior to the principalship compared to those who did not perceive themselves as more prepared in the areas of community collaboration, political, social, economic, legal, and cultural context, and curriculum, instruction and assessment. Effect size was measured for the statistically significance standards to determine practical significance. Each of the five statistically significant standards yielded a medium effect size indicating that the leadership …

An Exploration of the Ground Water Quality of the Trinity Aquifer Using Multivariate Statistical Techniques
The ground water quality of the Trinity Aquifer for wells sampled between 2000 and 2009 was examined using multivariate and spatial statistical techniques. A Kruskal-Wallis test revealed that all of the water quality parameters with the exception of nitrate vary with land use. A Spearman’s rho analysis illustrates that every water quality parameter with the exception of silica correlated with well depth. Factor analysis identified four factors contributable to hydrochemical processes, electrical conductivity, alkalinity, and the dissolution of parent rock material into the ground water. The cluster analysis generated seven clusters. A chi-squared analysis shows that Clusters 1, 2, 5, and 6 are reflective of the distribution of the entire dataset when looking specifically at land use categories. The nearest neighbor analysis revealed clustered, dispersed, and random patterns depending upon the entity being examined. The spatial autocorrelation technique used on the water quality parameters for the entire dataset identified that all of the parameters are random with the exception of pH which was found to be spatially clustered. The combination of the multivariate and spatial techniques together identified influences on the Trinity Aquifer including hydrochemical processes, agricultural activities, recharge, and land use. In addition, the techniques aided in identifying areas …

Aerospace and Defense Industries Online Recruiting of College and University Graduates: Strategies Toward Defining a Comprehensive Informational Benchmark
This qualitative, inductive study analyzed online recruiting information posted at the websites of five major aerospace and defense corporations to recruit college juniors, seniors, and recent graduates. Recruitment of this group is critical to staff the personnel for the scientific, technical, and management needs of aerospace and defense industries. The study sought: (1) to determine the use of multiple recruitment factors inferred from the literature and recommended for successful recruitment of college graduates, (2) to determine use of online social media (Facebook, Twitter, LinkedIn) to recruit this population, and (3) to explore commonalities among these corporations regarding online recruiting information to determine if a model for online recruitment now exists. A matrix of recruitment factors was developed from a review of the literature on the personnel needs of this industry and on effective recruiting factors for this group. Content analysis involved filtering information at each website with the matrix. Conclusions of this study include: (1) the matrix of recruitment factors and the rating scale developed for the purposes of this study provide a tool for researching, documenting, and comparing recruitment information on the internet; (2) that while these corporations represent the latest applications in technology in their manufacturing processes and …

Discretion, Delegation, and Professionalism: A Study of Outcome Measures in Upward Bound Programs
In our society, American citizens expect public policies to result in programs that address social problems in ways that are both efficient and effective. In order to judge if these two values are being achieved, public programs are often scrutinized through program monitoring and evaluation. Evaluation of public programs often is a responsibility delegated to local-level managers. The resulting discretion has to be balanced with the need for accountability that is also inherent in public programs. Evaluation is often difficult because outcomes are not readily measurable due to the complexity of the problems faced in the public setting. The Upward Bound program provides an example of this. Upward Bound provides services to students from low-income families and those in which neither parent holds a bachelor’s degree in order to increase the rate at which participants complete secondary education and enroll in and graduate from postsecondary institutions. Upward Bound is implemented and evaluated based upon specifications decided upon at the local level. This discretion granted to local level managers has resulted in wide variations in the way the program is being evaluated. This presents a problem for evaluation and has resulted in inconclusive results as to the success of the program. …
