Disparities exist in the U.S. between the health status of African American and Hispanic individuals and the health status of non-Hispanic Caucasian individuals across all age groups. Those minority individuals age 55 and over are more likely to suffer from specific health disparities in areas such as diabetes, heart disease, and cancer than their white majority counterparts. Among the most common chronic disorders experienced within this age group are obesity, type II diabetes and cardiovascular disease, all three of which collectively form what has recently become known as metabolic syndrome. As of 2004, metabolic syndrome is diagnosable once criteria are clinically significant for a variety of different risk factors designated by the World Health Organization. However, like many syndromes these criteria are not stable across individuals, and leaves variability between individuals being diagnosed. It has been seen that each of the above mentioned racial/ethnic groups experience the individual risk factors at disproportionate rates, making it plausible that metabolic syndrome could be experienced in distinctly different ways depending upon racial/ethnic background. Using two nationally representative data sets, it is first largely evident that African American and Hispanic individuals are reaching higher peak rates of diabetes and cardiovascular disease much earlier in …

This study examined the effectiveness of training Head Start teachers and aides in child teacher relationship training (CTRT). CTRT is based on child parent relationship therapy (CPRT) (Landreth & Bratton, 2006), a filial therapy model based on the principles of child-centered play therapy, and was adapted for the classroom. In this quasi-experimental design, 12 teacher/aide pairs (n = 24) were assigned to the experimental (n = 12) or active control group (n = 12). Children who scored in the Borderline or 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 = 54). Nine hypotheses were analyzed using a two factor repeated measures multivariate analysis to determine if the CTRT group and the active control group performed differently across time according to pre-, mid-, and posttest results of the C-TRF. Additionally, effect sizes were calculated to determine practical significance. Five hypotheses were retained at the .05 level of significance. Post hoc analysis was conducted to analyze the effects of the two phases of treatment. Results indicated that children in the experimental group made statistically significant improvements in externalizing problems (p = .003). Children of focus made statistically significant …

This study looked at leadership development at top performing nuclear plants in the United States. The examination of leadership development as actually practiced in the nuclear energy industry lead to the development of a best practice model. The nuclear industry is self-regulated through the Institute for Nuclear Power Operations (INPO). INPO has been evaluating nuclear plants over the past 15 years. Recently they have identified supervisor performance as a key factor in poor plant performance. INPO created a model for leadership development called Growing Industry Leaders. The nuclear industry has identified its aging workforce and subsequent loss of leadership as an emerging issue facing the nuclear industry in the next five to ten years. This initiative was aimed at both the supervisor shortfalls identified through plant evaluations and the state of the workforce within the nuclear industry. This research evaluated the elements of this model and compared them to a model of best practice. This research answered the following questions: What elements of leadership development should be included in leadership development programs? What would a model of best practice in leadership development look like? Data was collected from nine out of 103 top performing plants. Development activities were categorized by …

This causal-comparative and correlational study examined cross-cultural adaptability of randomly selected licensed dental hygienists, 1995-2005 graduates, practicing in the state of Texas and first and second-year dental hygiene students attending 5 randomly selected accredited 2 and 4-year dental hygiene schools in the state of Texas. A sample of 289 individuals: 194 enrolled students and 95 licensed dental hygienists, alumni of the 5 schools, completed the 50-item Cross-Cultural Adaptability Inventory (CCAI ®) and a brief demographic survey. The purpose of this study was to determine if statistically significant differences existed among and between licensed dental hygienists and first and second-year dental hygiene students in the state of Texas on a cross-cultural adaptability measure. The study also examined relationships among and between cross-cultural adaptability scores, as measured by the CCAI, and several independent variables. The data were analyzed by using the Statistical Package of Social Sciences (SPSS 12). Eight hypotheses related to group differences and relationships among and between groups and variables were tested. The groups were compared on total CCAI scores using a t-test, and on subscale CCAI scores simultaneously using a descriptive discriminant analysis (DDA). A 3X2 MANOVA was used to compare all groups simultaneously on subscale CCAI scores. The …

Abstract Attracting and developing information technology (IT) professionals is one of the top concerns for companies. Although much research has been conducted about the job behavior and attitudes of IT professionals over the last three decades, findings are inconclusive and contradictory. This suggests that something may be missing in how we examine this phenomenon. Most of this research is drawn from theories of motivation, very little examines the effect of social relationships on IT professionals' behavior and attitude. Yet, social capital theory suggests that job behavior and attitude may be greatly influenced by these relationships. This suggests that IT professionals' social capital warrants empirical examination. The primary research question that this dissertation addresses is how social capital affects IT professionals' work attitude and behavior including job satisfaction, organizational citizenship behavior, job performance and turnover intention. The research model in this dissertation examines the influence of three aspects of social capital on IT professionals' job attitude and work behavior: tie strength, the number of ties and the structural holes. Data were collected from 129 IT professionals from a range of jobs, organizations and industries. Results indicate that tie strength in the organization of an IT professional is positively related to job …

Medication non-compliance has become one of the most prevalent reasons for hospitalization and doctor's visits by the elderly. As the elderly population is more likely to have decreased cognitive abilities, it is suggested that neuropsychological factors, especially executive function, are more influential in medication non-compliance than once thought. This study looked at executive function performance on a traditional battery of neuropsychological tests, self-report of perceived ability to perform executive function tasks, and the newly developed Pillbox Test, a performance based IADL measure. The Pillbox Test is designed to replicate a type of medication-management specific IADL as a means to asses executive function. Standard executive function measures only tap a portion of executive function, but it is believed that the Pillbox Test incorporates all four theoretical domains of executive function. The multiple measures of executive function performance were compared in three prevalent subgroups of the elderly population (mixed neurological group, cardiac medical-control group, and healthy community-control group). Results found significant differences, where the community-control and cardiac groups outperformed the mixed neurological group on the large majority of executive function tasks. Smaller differences were also noted between the community-control and cardiac groups and between the cardiac and mixed neurological groups. Together, these …

Toward the end of his life, from 1908 to 1909, Gustav Mahler (1860-1911) composed Das Lied von der Erde (The song of the earth). This piece is a cycle of six song movements based on seven poems selected from Die chinesische Flötem - Nachdichtungen chinesischer Lyrik (The Chinese flute - free adaptation of Chinese lyric poetry) by Hans Bethge. The Chinese verse was written by Li-Po (numbers 1, 3, 4 and 5), Tchang-Tsi (number 2), and Mong-Kao-Jen and Wang-Wei (combined in number 6). Subsequently, in 1921, Arnold Schoenberg reduced the work to a simple chamber version transcription from Mahler's original massive score for full orchestra, a version completed in 1983 by Rainer Riehn. While the main melodic material in the vocal parts was maintained, the orchestral parts underwent substantial changes. This dissertation explores Mahler's reconfiguration of textual material and the setting of these texts in the orchestral medium. After consulting the various textual editions, I establish misreading and translational differences from the original Chinese through its various Western European incarnations; how and why Mahler chose the Bethge edition; what influenced his specific selection of poetry; and how these poems inform one another and the work as a whole. I also …

Composed in 1927 and dedicated to Segovia, Ponce's Sonata III, one of the staples of the classical guitar repertoire, is the focus of this paper. To put this piece into proper perspective among Ponce's other works, biographical information leading up to the composition of the piece is presented first. Each of the three movements is then analyzed with regard to formal construction as well as harmonic and melodic language. Analysis is an important precursor to actually playing the piece, as Sonata III is a work that departs from Ponce's previous compositional style. The main portion of this paper addresses the preparation and interpretation of Sonata III. The insight gained through initial analysis of the piece is used to arrive at a musically satisfying interpretation of the work. Specific performance suggestions are included. Technical issues are addressed and possible solutions are presented. Alternate fingerings are provided to alleviate some of the common technical challenges the guitarist will encounter. A transcription and discussion of the Segovia revisions are also present. The paper concludes with general suggestions for improving performance that would be applicable to other works for guitar as well. This synthesis of biographical information, analysis, editorial options and performance suggestions, has …

To form Cu interconnects, dual-damascene techniques like chemical mechanical planarization (CMP) and post-CMP became inevitable for removing the "overburden" Cu and for planarizing the wafer surface. During the CMP processing, Cu interconnects and barrier metal layers experience different electrochemical interactions depending on the slurry composition, pH, and ohmic contact with adjacent metal layers that would set corrosion process. Ruthenium as a replacement of existing diffusion barrier layer will require extensive investigation to eliminate or control the corrosion process during CMP and post CMP. Bimetallic corrosion process was investigated in the ammonium citrate (a complexing agent of Cu in CMP solutions) using micro test patterns and potentiodynamic measurements. The enhanced bimetallic corrosion of copper observed is due to noble behavior of the ruthenium metal. Cu formed Cu(II)-amine and Cu(II)-citrate complexes in alkaline and acidic solutions and a corrosion mechanism has been proposed. The currently used metallization process (PVD, CVD and ALD) require ultra-high vacuum and are expensive. A novel method of Si surface metallization process is discussed that can be achieved at room temperature and does not require ultra-high vacuum. Ruthenation of Si surface through strong Si-Ru covalent bond formation is demonstrated using different ruthenium carbonyl compounds. RBS analysis accounted for …

The Sonata for Trumpet and Piano by Peter Maxwell Davies is one of his earliest works, and a notoriously difficult work to perform. While using serialism and other twentieth-century compositional techniques, this work also uses older historical forms, including sonata-allegro and sonata-rondo forms. An analysis of the work is presented, identifying the older historical forms, and considerations for performers when making decisions on how to perform the work are provided.

Compassion is one of the fundamental experiences which signify human existence. Person perception is the constructive process with which we form an opinion or judgment of another person. Two experiments (N =277) were conducted in this study. Experiment 1 examined the effects of a mindfulness meditation on compassion in a large sample of young adults. Participants (n =76) were randomly assigned to three groups. Participants in group 1 received the mindfulness meditation, group 2 received an alternate version of the mindfulness meditation (self-focus only), and participants in group 3 were asked to complete an attention task and read a geological text. It was hypothesized that mindfulness meditation is significantly associated with the experience of compassion. Results showed that participants in the experimental group 1 experienced significantly higher levels of compassion compared to participants in the control group 3. The participants in group 2 were not different from experimental group 1 or from control group 3. Gender differences in the effects of meditation on compassion were explored. Different measures yielded conflicting evidence for gender differences in experienced compassion. For the second experiment a Solomon four-group experimental design was employed to examine the possible effects of compassion on person perception. Participants (n …

Hard real-time systems in robotics, space and military missions, and control devices are specified with stringent and critical time constraints. On the other hand, soft real-time applications arising from multimedia, telecommunications, Internet web services, and games are specified with more lenient constraints. Real-time systems can also be distinguished in terms of their implementation into preemptive and non-preemptive systems. In preemptive systems, tasks are often preempted by higher priority tasks. Non-preemptive systems are gaining interest for implementing soft-real applications on multithreaded platforms. In this dissertation, I propose a new algorithm that uses a two-level scheduling strategy for scheduling non-preemptive soft real-time tasks. Our goal is to improve the success ratios of the well-known earliest deadline first (EDF) approach when the load on the system is very high and to improve the overall performance in both underloaded and overloaded conditions. Our approach, known as group-EDF (gEDF), is based on dynamic grouping of tasks with deadlines that are very close to each other, and using a shortest job first (SJF) technique to schedule tasks within the group. I believe that grouping tasks dynamically with similar deadlines and utilizing secondary criteria, such as minimizing the total execution time can lead to new and more …

This study seeks to provide information relevant to public policy that will lead to increased access and utilization among this vulnerable population and to reinforce the validity of the behavioral model for vulnerable populations. This study is a secondary analysis of data collected in a study that examined adult, working-aged patients within the John Peter Smith Health Network, which is a large, urban, tax supported county health care system in Fort Worth, Texas. From a sampling frame of 10,000 patients, the study analyzed data for 243 low-income, white, working-age males, collected from computer assisted telephone interviews in 2000. Cross-tabulations and bivariate logistic regressions were used to analyze the effect of 8 independent variables (age, marital status, insurance, employment status, a usual source of care, competing needs, experiences with paperwork, and perceived health status upon 5 dependent variables pertaining to unmet health care, unmet prescription medicine needs, unmet dental needs, utilization of doctors in emergency departments, and overnight hospital stays. The results show the safety net system is failing to meet the needs of this vulnerable population. The findings indicate white men who found it necessary to forgo health care due to other needs were almost five (4.973) times as likely …

This study examines the factors that have contributed to the success of some Central and Eastern European countries to improve their health care sector in the post communist period, while leaving others to its demise. While most literature has been focused on the political and economic transition of Eastern Europe, very little research has been done about the welfare aspects of the transition process, especially the health care sector. While the focus on political consequences and main macroeconomic reforms has shed light on many important processes, the lack of research of health care issues has lead to consequences on our ability to understand its impact on the future of the new democracies and their sustainability. This model looks at the impact of international (World Bank) and domestic institutions, corruption and public support and how they affect the ability of some countries to improve and reform their health care sector in the post-transition period.

This study employed a multivariate, multidimensional approach to understanding psychosocial and personality variables associated with institutional maladjustment and recidivism among youthful offenders. Participants included nine hundred serious and chronic male youthful offenders incarcerated in the Texas Youth Commission (TYC); sample sizes varied by analysis. Empirically-validated psychosocial factors (e.g., intelligence, home approval status), past criminal history variables, and two self-report personality measures of empathy and hostility were entered into hierarchical regression and structural equation modeling (SEM) analyses to predict institutional behavior and recidivism at one- and three-year intervals after release from the TYC. Confirmatory factor analysis of the personality measures revealed one underlying factor indicative of their theoretical constructs of empathy and hostility. Some differences were noted between youth in the specialized treatment programs; however, effect sizes were small to moderate. Overall, regression and SEM results indicated the variables accounted for a meaningful proportion of the variance in the outcomes. Specifically, although length of stay in the TYC was associated with institutional behavior, younger age of onset, higher hostility, and greater home disapproval also contributed significantly. Past criminal behavior was predictive of future reoffending, but lower empathy, greater home disapproval, and younger age of onset accounted for a substantial portion of …

The purpose of this study was to determine whether working in the field of deaf education, as opposed to general education, results in a higher level of technology integration. A secondary goal was to determine if deaf educators who are deaf integrate technology at a higher level than their hearing counterparts. The instrument chosen for this study was the LoTi Technology Use Profile, a tool used to explore the role of technology in the classroom. A total of 92 participates were included in the study of which 48 were regular educators and 44 were deaf educators. The participants were selected from a population pool whereby teachers were presumably pre-disposed to using technology based upon their attendance at a technology training session in the form of a conference or a class. Deaf educators as a whole did not perform as well as general educators on the LoTi scales. Given the fact that the technology-minded general educators who comprised the sample population of this study scored exceptionally high on the LoTi scales, further research is needed to ensure comparability between the two groups. The findings of the current study do suggest, though, that deaf educators who are deaf have the potential to …

This study examined the home-based family literacy practices of one Hispanic family, especially focusing on the parents' memories of home-based and school-based literacy activities, current home-based literacy activities and functions, and the interface of home-based family literacy practices and school-based literacy expectations. Ethnographic data offered insight into the understanding that literacy acquisition begins in the home and is dependent and reflective of literacy experiences that are sociocultural based. These home-based family literacy activities and functions are broad in scope and are valuable forms of literacy. However, these activities of marginalized families are often regarded as unimportant and/or unrelated to school-based literacy expectations, and therefore inferior. In response to this perceived mismatch between home-based family literacy activities and school-based literacy expectations, educators approached families from a deficit perspective. This deficit assumption created a sense of devalue on the part of the parents, who assisted their children by culturally and socially relevant means. To meet the school-based literacy expectations familial relationships were jeopardized as the pressure, frustration, and guilt from educators can result in emotional and physical abuse from mother to her children.

The purpose of this study was to determine the relationship between principals' leadership styles and principals'/teachers' implementation of technology. The Leadership Effectiveness and Adaptability Description (LEAD) Self was used to identify the primary and secondary leadership styles of principals. The Level of Technology Implementation (LoTi) Questionnaire was used to identify the level of technology implementation (LoTi), personal computer use (PCU) and current instructional practice (CIP) scores for both teachers and principals. Data collected from 390 K-12 teachers and 22 principals of three large suburban districts in the Dallas-Fort Worth Metroplex was included in data analysis. The findings suggest that differing leadership styles do play a role in the LoTi, PCU, and CIP scores among teachers. Based on descriptive statistics it was determined that teachers with "participating" principals had higher mean LoTi and PCU scores than those with "telling" and "selling" principals. The difference in the mean PCU scores was statistically significant (p<.05) for teachers with "selling" and "participating" principals. Results also showed there was a statistical significance (p<.05) in the mean PCU and CIP scores of teachers working for principals with weak and high adaptability. Due to the low number of principals participating in this study, there is a need …

This dissertation: (a) investigated the degree to which the squared canonical correlation coefficient is biased in multivariate nonnormal distributions and (b) identified formulae that adjust the squared canonical correlation coefficient (Rc2) such that it most closely approximates the true population effect under normal and nonnormal data conditions. Five conditions were manipulated in a fully-crossed design to determine the degree of bias associated with Rc2: distribution shape, variable sets, sample size to variable ratios, and within- and between-set correlations. Very few of the condition combinations produced acceptable amounts of bias in Rc2, but those that did were all found with first function results. The sample size to variable ratio (n:v)was determined to have the greatest impact on the bias associated with the Rc2 for the first, second, and third functions. The variable set condition also affected the accuracy of Rc2, but for the second and third functions only. The kurtosis levels of the marginal distributions (b2), and the between- and within-set correlations demonstrated little or no impact on the bias associated with Rc2. Therefore, it is recommended that researchers use n:v ratios of at least 10:1 in canonical analyses, although greater n:v ratios have the potential to produce even less bias. …

The purpose of this research is to empirically investigate consumers' health care decision choices in a dynamic market setting. The unprecedented demands on the U.S. health care system coupled with the mounting controversies surrounding health care reform suggest that consumers' health care decisions warrant empirical research attention. Toward this end, this dissertation empirically explored (1) the characteristics of consumers who possess a willingness to use non-conventional treatments over conventional treatments, (2) the characteristics of consumers who elect self-medication in lieu of health care practitioner-directed medication, and (3) the salient dimensions of consumers' channel choice for the procurement of health care products. Each of these decision choice factors were tested across two U.S. generational segments to assess whether differences existed across Baby Boomers' and Gen Yers' health care decision choices. The conceptual framework for empirical assessment is Bandura's (1986) social cognitive theory. From Bandura's social cognitive theory, a general model of healthcare decision choice is proposed to assess consumers' states of mind, states of being and states of action (decision choice). Results indicate that social cognitive factors (e.g., self-efficacy, objectivism) play an important role in each of the decision domains explored in this dissertation. Moreover, health value was found to be …

This study examined the distinct effects of partner violence and psychological abuse on women's mental health over time. Latent growth modeling was used to examine stability and change over time, evaluating the course and consequences of each form of abuse. The size of women's social support network was examined as a mediator. The sample consisted of 835 African American, Euro-American, and Mexican American low-income women. Participants who completed Waves 1, 2, 3, and 5 were included in the study (n = 585). In general, partner violence decreased over time for all groups, while psychological abuse decreased over time for only Euro-American women. Whereas initial and prolonged exposure to psychological abuse was related to and directly impacted women's mental health, partner violence was only related to initial levels of mental health. Surprisingly, social support was only related to initial violence and distress and had no impact on the rate of change over time. These results have important implications for researchers and health care professionals. First, differences in the pattern of results were found for each ethnic group, reaffirming the notion that counselors and researchers must be sensitive to multicultural concerns in both assessment and intervention. For example, psychological abuse had a …

Vulnerable populations comprise a growing number of people living with HIV/AIDS and are at increased risk for poorer health outcomes. The purpose of this research was to approximate the effect of the Ryan White CARE Act on the health status of people living with HIV/AIDS who were receiving medical care in the United States. The vulnerable populations model was utilized to identify appropriate variables for analysis as well as to provide a sequencing for the testing of models. Data analyzed in this study came from the 1996 Baseline Survey of the HIV Cost and Services Utilization Study (HCSUS), a cooperative study between RAND and the Agency for Health Care Policy and Research (now known as the Agency for Health Care Quality and Research). Three analyses sequences, using different dependent variables, to estimate health status were conducted. In the first analysis, health status was measured by CD-4 count and stage of illness. In the second analysis, only CD-4 counts were used for health status. In the final analysis, health status was estimated based on AIDS diagnosis. Each of the three analyses included the same independent variables: race, gender, education, sexual orientation, income, insurance status, region of the country, receipt of case …

The purpose was to analyze Turkey's current music teacher training curriculum as situated in the centralized educational system, focusing on the extent to which the written document (1) reflects the core elements of the overall centralized educational system; (2) prescribes the nature of teaching materials and methods, assessment tools and other forms of evaluating and monitoring performance as teachers and musicians; and (3) acknowledges cultural diversity by addressing repertoire, musical activities and concepts according to geographic and cultural regions. Qualitative-descriptive and quantitative content analysis, including the methods of (a) Inverse document frequency and (b) relevance feedback model, were the analytic tools. Of the required 147 credit hours, 138 are the core. The music core consists of 87 (63%) and the non-music core of 51 credit hours (37%). On paper, there is a conceptual overlap in wording between the music core, the general core, and the teacher training core, suggesting curricular cohesion and consistency. Noticeably less cohesion exists between the document and three major policy papers on teacher competencies. By word count, preparing teachers for instruction in Turkish folk music and multicultural issues appears to hold a low priority in the curriculum. However, course descriptions, where they exist, speak to skills …

With three homogenous caregiver groups (i.e., Alzheimer's caregivers, grandparents raising grandchildren, parents), caregiving styles were explored to determine their reliability and validity, their unique role in predicting caregiver outcomes, and their differences between groups of caregivers. A conceptual framework was adapted to determine the impact of contextual variables, caregiving styles, caregiver appraisal, and mediating variables on caregiving outcomes. A more concise version of the Caregiving Style Scale (CSS) was developed with 49 items yielding an internal consistency coefficient of .74. As expected, three caregiving styles emerged and were positively related to the parallel parenting styles. Across the caregiver samples, there were positive relationships among caregiving style dimensions within the same caregiving style, while those from opposing caregiving styles tended to have negative relationships indicating good convergent and discriminant validity. Authoritative caregiving style dimensions were generally associated with healthier functioning, while authoritarian and permissive caregiving style dimensions were correlated with less healthy functioning. Caregiving style dimensions were among the predictors of several outcome measures, highlighting the importance of their placement in the conceptual framework for caregiver stress and coping. Generally, an unexpected finding was that authoritative caregiving style dimensions tended to predict less adaptive caregiving outcomes, particularly for parents and grandparents, …
