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 …

Many school districts consider literacy and oral language as a top priority for pre-kindergarten students. In the district under study, pre-kindergarten English language learner (ELL) students are encouraged to attend a special summer school program to increase their oral language ability in English. This study compared three groups of children: ELL students attending summer school v. ELL students not attending summer school v. English speaking students not attending summer school. The students' primary reading inventory scores from the end of pre-kindergarten to the middle of kindergarten in the areas of reading, writing and oral language were compared. As expected, ELLs who attended summer school showed significant growth in oral language development from the beginning of summer school to the end of summer school. While it was hypothesized that ELL students attending summer school would show more improvement in oral language than other children over time, there was no significant difference between summer school and non-summer school children's scores by the middle of kindergarten.

The current study seeks to examine the relationships between perceptions of employee empowerment and perceptions of leadership, span of control, and industry type. Participants were gathered from an archival source employing a high school alumni e-mail group (n = 361) and a survey from 9 organizations (n = 647) and combined into a larger sample (n = 1008). The participants took Bodner's (2005) Assessment of Employee Empowerment and Assessment of Empowering Leadership instruments. Support was found to suggest that people report being less empowered than they believe that top management would report about them. Also, participants reported that their leader was less empowering than they believed top management would report about the leader. Span of control was found to impact perceptions of empowerment. Production workers reported feeling more empowered than workers in service industries. Participants did not report that leaders were more empowering if they were higher in the hierarchy (executive) than lower levels (coach, employee). Also, a respondent's position did not affect the relationship between job type and feelings of empowerment. This study suggests that the organizational design (span of control) and industry type may affect empowerment initiatives, while lower levels of the organization may view empowerment much differently …

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 …

The working cowboy remains part of the contemporary culture of Texas. A visual record of him appeared early in the state's history, in daguerreotypes, followed by representations in contemporary black and white as well as color photographs, film and video. Although the way of life for the Texas cowboy has changed, it remains a thriving part of the Texas economy, society, and culture. Moreover, the image of the cowboy has permeated popular culture and fine art. This paper explores what late twentieth century popular culture and fine art images of the cowboy signify, emphasizing aspects of how they signify in relation to an existing tradition of photographic representations. Using Barthes' "Myth Today," it considers how the documentary aspect of early photographic representations of cowboys is transformed in contemporary popular culture and fine art to become mythology, for example, by the exaggeration of features of dress to connote ideals allegorically.

Counter-productive workplace behavior (CWB) is defined as any intentional behavior on the part of an organization member viewed by the organization as contrary to its legitimate interests. A growing body of literature reveals that individual variables and pre-employment integrity tests can play a strong role in the prediction of CWB. The empirical literature has failed to clarify which type of individual level antecedents, or types of integrity test items, are more predictive of CWB. The current study evaluated data collected from restaurant employees (N=464) that measured items relating to personality tendencies, attitudes toward acceptance of counter-productive behaviors, work and high school background, and admissions of counter-productive behavior. A confirmatory factor analysis revealed a mediocre fit to a typology of CWB (interpersonal CWB vs. organizational CWB). Correlation analysis revealed that only specific attitudinal items and empirically keyed biodata items were significantly related to CWB. Hierarchical regression analysis found that attitudinal items paralleling admissions of CWB contributed variance beyond that of other personality and work and high school background antecedents.

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 …

Hafnium based high-κ dielectrics are considered potential candidates to replace SiO2 or SiON as the gate dielectric in complementary metal oxide semiconductor (CMOS) devices. Hydrogen is one of the most significant elements in semiconductor technology because of its pervasiveness in various deposition and optimization processes of electronic structures. Therefore, it is important to understand the properties and behavior of hydrogen in semiconductors with the final aim of controlling and using hydrogen to improve electronic performance of electronic structures. Trap transformations under annealing treatments in hydrogen ambient normally involve passivation of traps at thermal SiO2/Si interfaces by hydrogen. High-κ dielectric films are believed to exhibit significantly higher charge trapping affinity than SiO2. In this thesis, study of hydrogen trapping in alternate gate dielectric candidates such as HfO2 during annealing in hydrogen ambient is presented. Rutherford backscattering spectroscopy (RBS), elastic recoil detection analysis (ERDA) and nuclear reaction analysis (NRA) were used to characterize these thin dielectric materials. It was demonstrated that hydrogen trapping in bulk HfO2 is significantly reduced for pre-oxidized HfO2 prior to forming gas anneals. This strong dependence on oxygen pre-processing is believed to be due to oxygen vacancies/deficiencies and hydrogen-carbon impurity complexes that originate from organic precursors used in …

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.

This study addresses a tension in contemporary studies of public memory between ideology criticism and postmodern critique. Both strategies of reading public memory rely on a representational logic derived from the assumption that the source for comparison of a memory text occurs in a more fundamental text or event. Drawing heavily from Michel Foucault, the study proposes an alternative to a representational reading strategy based on the concepts of regularity, similitude, articulation, and cultural formation. The reading of Vietnam Veterans Memorial and the Galveston County Vietnam Memorial serves as an example of a non-representational regularity enabled by the cultural formation of pastoral power.

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 …

One of the greatest mysteries in the history of music is the castrato singers of the Baroque era. Castration has existed for many thousands of years, but for the first time in history, it was used for artistic purposes. Who were these men who seemingly gave up their masculinity for the sake of music? By examining the time period and circumstances in which these musicians lived, an answer may be found. Exploring the economic, social, and political structure of the 17th and 18th centuries may reveal the mindset behind such a strange yet accepted practice. The in-depth study of their lives and careers will help lift the veil of mystery that surrounds them. Was their physical sacrifice a blessing or a curse? Was it worth it?

This national study, focusing on job satisfaction within juvenile facility directors, was conducted by the means of a survey. The study is longitudinal in nature; the survey was conducted in 1995 and 2000. Other past studies have focused on line level employees, guards, and the juveniles, but few have concentrated on juvenile facility directors. Literature on directors is currently lacking, this continuous study will give a better ongoing perspective of their attitudes and beliefs. Findings from this particular study will help to address current concerns inside of the system, starting at the apex. The survey's goal is to correlate factors that have a direct impact on their job satisfaction. Results indicate that staff issues have a dramatic impact on a director's job satisfaction.

The Texas Open Beaches Act states that the public beach extends from the water up to the line of vegetation. Once a privately-owned property is submerged, it transfers into state ownership. Because of severe erosion and the shifting nature of vegetation, the Village of Surfside has lost several rows of houses and streets and, currently, over thirty houses are located on the public beach obstructing public access in violation of the Texas Open Beaches Act. The extreme erosion in this small village on the Texas Gulf Coast puts homeowners, property owners, legislators, and beachgoers in difficult positions and many are at odds with one another. The documentary film is structured around rental property owner Russell Clinton, environmentalists Ellis Pickett and Jeff Hooton, and former State Senator A.R. "Babe" Schwartz.

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 …

Following the Glorious Revolution in 1688, the British North American colonies interpreted Parliament's success in removing arbitrary governmental practices and establishing a balanced government as a victory for local representative government. Within these colonies, merchants secured their influence in local government in order to protect their profits and trade networks. The New England merchants that resettled in Nova Scotia in the 1750s successfully established a local government founded upon their rights as British subjects. The attempt by the British government to centralize the imperial administration in 1763 and the perceived threat of reintroducing arbitrary rule by Parliament was a direct threat to the colonial governmental system. Although Nova Scotia chose loyalism in 1775-1776, this decision did not stem from isolation or a differing political philosophy. In fact, it was their cultural and political similarities that led Nova Scotia and New England to separate paths in 1776. Nova Scotia merchants controlling the Assembly were able to confront and defeat attempts that threatened their influence in local politics and on the local economy. With the threat to their authority defeated and new markets opening for the colony, the Nova Scotia merchant class was able to preserve the status quo in local government.

I believe that poetry has survived for thousands of years because it provides people with a transpersonal connection that they can't find elsewhere. I look for poetry that is more than an emotional expression, more than witty word play, and more than an interesting observation. I want poetry to give me that inspirational spark, that glimpse into a world beyond my own. Poems that succeed in doing this force me into a perspective that I haven't previously imagined by yoking together two or more seemingly disparate elements. This tension between the old elements and the new link between them creates energy for the poem. This poetic nexus contributes to the transpersonal experience that I seek.

Caring for a family member or loved one with dementia places a heavy burden on those providing the care. Caregivers often develop chronic depression because of having to deal with this burden. A great deal of literature has been published discussing coping effectiveness, effects of social support, and other internal and external means of support for the caregiver. However, little has been written about the changes, if any, in depression that the caregiver experiences after the termination of care, either through institutionalization or death of the person with dementia. This study examined whether there is a change in depression of spousal caregivers after institutionalization of the dementia care recipient as well as any changes in depression that may have occurred as a result of the death of the dementia care recipient. Two theoretical models, the wear and tear model and the adaptation model were discussed in terms of caregiver depression after institutionalization of the dementia care recipient. Two other theoretical models, the relief model and the stress model, were discussed in terms of caregiver depression after the death of the dementia care recipient. Datasets from the National Institute on Aging sponsored Health and Retirement Study were analyzed. Results indicate that …

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 …

Susceptibles-infectives-removals (SIR) and its derivatives are the classic mathematical models for the study of infectious diseases in epidemiology. In order to model and simulate epidemics of an infectious disease, a global stochastic field simulation paradigm (GSFS) is proposed, which incorporates geographic and demographic based interactions. The interaction measure between regions is a function of population density and geographical distance, and has been extended to include demographic and migratory constraints. The progression of diseases using GSFS is analyzed, and similar behavior to the SIR model is exhibited by GSFS, using the geographic information systems (GIS) gravity model for interactions. The limitations of the SIR and similar models of homogeneous population with uniform mixing are addressed by the GSFS model. The GSFS model is oriented to heterogeneous population, and can incorporate interactions based on geography, demography, environment and migration patterns. The progression of diseases can be modeled at higher levels of fidelity using the GSFS model, and facilitates optimal deployment of public health resources for prevention, control and surveillance of infectious diseases.
