Medication adherence is a formidable challenge for the elderly who may have several prescribed medications while dealing with limited incomes and declining health. The primary purpose of this study was to evaluate the Liberty 6000, an automated capsule and tablet dispenser that provides proper medication dosages and is intended to encourage and track medication adherence. Seven focus groups were assembled; these comprised 49 men and women ages 65 to 98 years of Black, Anglo, and Hispanic descent who met the following criteria: living independently or semi-independently, had suffered one or more impairments, and were taking at least three prescription medications. Each focus group session lasted 90 minutes and was tape-recorded and transcribed verbatim, resulting in about 2,600 lines of text. Each question was designed to be open-ended to avoid introducing any bias that might influence the response. The Health Belief Model conceptually guided the study that addressed perceptions of illness susceptibility and severity, barriers, benefits, and cues to action associated with medication adherence. Main benefits of taking medications included avoiding inherited illnesses (or tendencies for illnesses), and reducing illness symptoms. Barriers to taking medications included forgetting, dexterity problems, and high cost. Benefits of the proposed intervention included reminding, caregiver notification, …

Concerto for Solo Percussion and Concert Band was commissioned by Staff Sergeant Rone Sparrow, a percussionist with the West Point Military Academy Band. Funding for the project was provided by the Barlow Foundation. The piece was premiered April 13, 2005 in the Eisenhower Hall Theater at West Point, New York. Rone Sparrow performed with the USMA band, and Colonel Thomas Rotondi Jr., Commander/Conductor, conducted the piece. The concerto consists of three movements, and each movement features a different instrument: the first features marimba, the second, vibraphone, and the third movement features the drum kit together with a rhythm section (piano, bass, and drums). In addition to the piece, the dissertation paper discusses important technical detail related to the piece, including: harmony, form, rhythm, programmatic ideas as they relate to motivic strands, and the process of generating and discarding material. The paper also focuses on a number of factors that were influential to the piece, such as postmodern philosophy.

This project utilizes a case study approach to explore the various ways in which the portrayals of gay people have changed on American television. Three contemporary programs - Will & Grace, Queer Eye for the Straight Guy and The L Word - are examined as examples of how far American television has progressed in terms of treating gay people with respect. Whether those shows move beyond merely presenting gay characters and into a level of actively challenging mainstream views on gay people is also examined. Findings suggest different factors affect the ability of the individual programs to test said views - including the genres to which each belongs, and their presence on network television (Will & Grace), basic cable (Queer Eye for the Straight Guy) or premium cable (The L Word). While all three programs show some tendencies toward queerness, they also take steps toward negotiating with mainstream culture, indicating that complete queerness may be an unattainable goal on American television.

The career development of students, demonstrated by students' career interest, is important for a more effective career education program. This study focused on the career choices of fifth grade students through the use of a career interest inventory before and after the use of a career education program. The design was experimental, and the purpose was to determine if there were differences in the career interest of fifth grade students who participated in a career education program compared with the career interest of fifth grade students who did not participate in a career education program. The COPS-PIC Picture Inventory of Careers (COPS-PIC) was used as a pretest and posttest for fifth grade students to determine baseline career interests. The COPS-PIC career inventory results were incorporated into the career education program and served as a career planning guide for incorporating students' input into career choices and exploration of those choices for a better understanding of the process of finding out who they want to be and what type of careers exists. The experimental group was provided instruction and career exploration opportunities for 4 weeks. The control group was not provided career education instruction and career exploration opportunities. This study suggests that …

Voluntary turnover has historically been a problem for today's organizations. Traditional models of turnover continue to be utilized in a number of ways in both academia and industry. A newer model of turnover, job embeddedness, has recently been developed in an attempt to better predict voluntary turnover than existing models. Job embeddedness consists of organizational fit, organizational sacrifice, and organizational links. The purpose of this study is to two fold. First, psychometric analyses were conducted on the job embeddedness model. Exploratory factor analyses were conducted on the dimensions of job embeddedness, which revealed a combined model consisting of five factors. This structure was then analyzed using confirmatory factor analysis, assessing a 1, 3, and 5 factor model structure. The confirmatory factor analysis established the use of the 5 factor model structure in subsequent analysis in this study. The second purpose of this study is to compare the predictive power of the job embeddedness model versus that of the traditional models of turnover. The traditional model of turnover is comprised of job satisfaction, organizational commitment, and perceived job alternatives. In order to compare the predictive power of the job embeddedness and traditional model of voluntary turnover, a series of structural equation …

Few studies have systematically evaluated whether preferences can reliably be identified using brief procedures. Typically, studies have used brief procedures to select potential reinforcers for use in intervention procedures. A total of 17 food and leisure paired-choice preference assessments were administered to 10 subjects in order to evaluate the extent to which the results of a brief (i.e., single-session) assessment correspond with those from more extended procedures (i.e., 5 sessions). Eleven out of the 17 brief and extended assessments identified the same stimulus as the most preferred (highest rank). Outcomes suggest that a brief assessment can be useful when a single, potent reinforcing stimulus is desired, and an extended assessment should be conducted when a larger number of preferred stimuli is desired.

Two series monodispersed nanoparticles of hydroxylpropyl cellulose (HPC) and functionalized poly-N-isopropylamide (PNIPAM) particles have been synthesized and used as building blocks for creating three-dimensional networks, with two levels of structural hierarchy. The first level is HPC nanoparticles were made from methacrylated or degradable cross-linker attached HPC. These nanoparticles could be stabilized at room temperature by residual methacrylate or degradable groups are present both within and on the exterior of HPC nanoparticles. Controlled release studies have been performed on the particle and networks .The nearly monodispersed nanoparticles have been synthesized on the basis of a natural polymer of hydropropylcellulose (HPC) with a high molecular weight using the precipitation polymerization method and self-assembly of these particles in water results in bright colors. The HPC nanoparticles can be potential using as crosslinkers to increase the hydrogels mechanical properties, such as high transparency and rapid swelling/de-swelling kinetics. The central idea is to prepare colloidal particles containing C=C bonds and to use them as monomers - vinylparticles, to form stable particle assemblies with various architectures. This is accomplished by mixing an aqueous suspension of hydrogel nanoparticles (PNIPAM-co-allylamine) with the organic solvent (dichloromethane) to grow columnar crystals. The hydrogels with such a unique crystal structure behavior …

Pigeons were trained on a zero-delay identity match-to-sample task. Experiment 1 started with every correct match reinforced with grain access and subsequent conditions include higher fixed-ratio values. Experiment 2 included the same fixed-ratio values as experiment 1 with and without a limited hold (LH) on the opportunity to select a comparison stimulus. Prior research suggested that trials after reinforcement would have an increased likelihood of error, and that these errors would be reduced in LH conditions. Results confirmed this expected error pattern and in most LH conditions errors were reduced early in the ratio.

When the Bush administration set out to revolutionize public education through the requirements commanded by No Child Left Behind Act of 2001 (NCLB), framers of the legislation chose language that appeared inclusive of all students in U.S. schools. The law demands that English language learners take the mandated exams early in their academic careers in the United States even though research indicates most will fail due to lack of time to acquire sufficient language proficiently to demonstrate their learning on the exams. Viewed through a critical theory lens, the inclusive nature of NCLB is in fact, oppressing ELL students. One district in Texas The study involved ELL students in grades 1-12 in a school district in North Central Texas that uses its family literacy center as an intervention to aid ELL families in English language acquisition. Students fell into three categories: students and parents who attend the family literacy center English classes, students whose parents attend the family literacy center English classes but the students do not attend, and students and parents who do not attend the family literacy center English classes. The quantitative data for the study were reading and math Texas Assessment of Knowledge and Skills (TAKS) and …

This project investigated the relations between recalled job-satisfaction, ability, and task demands in Vietnam era helicopter aviators. It attempted to detect and describe factors present in a dangerous combat environment which may influence some individuals to enjoy and take satisfaction at being exposed to, creating, and participating in the dangerous and life threatening violence involved in helicopter combat. Participants were 30 pilots and crew members retired from the 335th Assault Helicopter Company who were all actively involved in combat in Vietnam from 1968 to 1970. This study found that developing a love of war is correlated with anger during combat. The love of war is not correlated with PTSD processes nor is it correlated with specific personality dimensions. The love of war research is a new area. The questions were used to operationalize the love of war represent a significant limitation. This method of operationalizing the love of war concept does not make fine discriminations has questionable content validity. To facilitate accuracy in discriminating between participants when conducting future research in the area, researchers could benefit from constructing a measure with greater content validity.

Banach's contraction principle is probably one of the most important theorems in fixed point theory. It has been used to develop much of the rest of fixed point theory. Another key result in the field is a theorem due to Browder, Göhde, and Kirk involving Hilbert spaces and nonexpansive mappings. Several applications of Banach's contraction principle are made. Some of these applications involve obtaining new metrics on a space, forcing a continuous map to have a fixed point, and using conditions on the boundary of a closed ball in a Banach space to obtain a fixed point. Finally, a development of the theorem due to Browder et al. is given with Hilbert spaces replaced by uniformly convex Banach spaces.

Natural language is inherently ambiguous. For example, the word "bank" can mean a financial institution or a river shore. Finding the correct meaning of a word in a particular context is a task known as word sense disambiguation (WSD), which is essential for many natural language processing applications such as machine translation, information retrieval, and others. While most current WSD methods try to disambiguate a small number of words for which enough annotated examples are available, the method proposed in this thesis attempts to address all words in unrestricted text. The method is based on constraints imposed by syntactic dependencies and concept generalizations drawn from an external dictionary. The method was tested on standard benchmarks as used during the SENSEVAL-2 and SENSEVAL-3 WSD international evaluation exercises, and was found to be competitive.

This study focused on the identification of career paths that led to the Texas public school superintendency, including an examination of career path differences associated with gender, ethnicity, and district type, and on the identification of the career path positions superintendents perceived as being the most beneficial in preparing them for the superintendency. Additionally, the study examined place-bound versus career-bound superintendents. The most common career path to the Texas public school superintendency was secondary teacher, secondary principal, and superintendent. Female administrators and administrators who worked in large districts were more likely to take the director route to the superintendency. Additionally, most major urban superintendents took the director route to the superintendency. Ethnicity was not a significant factor in determining the career path to the superintendency. A significant correlation did exist between educational attainment and the secondary teacher, secondary assistant principal, secondary principal, assistant superintendent, superintendent career path. A higher representation of superintendent respondents who held earned doctorates existed in that career path than in any of the other career path groups. While educational attainment was important in higher paying districts, most Texas superintendents did not hold doctorates. Few held doctorates from the most prestigious, nationally recognized universities.

In late 20th century America, multiculturalism emerged as a doctrine of equal respect and a popular ideological framework for resolving intergroup relations. Despite its dramatic presence, many sociologists conclude that the rather vigorous and often contentious academic inquiries into multiculturalism left us without a solid understanding of its significance. In this dissertation I examine survey and personal interview data to more clearly identify patterns of ideological support for multiculturalism or assimilation in the U.S. public and to isolate the motivations for their preferences. Findings based on the survey data indicate that, despite multiculturalism's symbol appeal, it does not seem to guide preferences in favor of or opposition to assimilation/multiculturalism among members of most groups. According to the quantitative data, support for intermarriage is one of the few variables that positively correlates with preferences for assimilation. The interview data indicate a strong tendency among many participants to conflate the meaning of multiculturalism and assimilation. Despite their stated aspirations, many self-identified multiculturalists do not favor cultural pluralism. Apparently a significant number of the interview participants use a synthesis of multiculturalism and assimilation to frame their preferences for social convergence within an assimilationist paradigm - a perspective that only marginally resembles multiculturalism's doctrine …

This study identified and described the experiences of twelve African American men that influenced the choice to participate in postsecondary education. This qualitative study used a phenomenology framework to determine 1) the formation of predisposition in the college choice process, 2) the messages received about college from influential people, and 3) perception and interpretation of the importance of a college degree. The overall theme arising from the data is that the college choice process was complicated and inconsistent; however, ten of the twelve participants completed some type of postsecondary training. Deficient messages about postsecondary education manifested as low parental support for college attendance, low academic expectations, withholding of important information from school officials and little or no exposure to postsecondary institution campuses or students. Influential people for the participants ranged from parents to themselves, and from a combination of characteristics from different people, to peers, to no one. The informants did not consistently identify their role model as the one who influenced them to attend college. The perception of the value of a college degree varied among the participants. Some described the degree as a requirement for success; others felt that strengthening family and achieving financial independence was more important.

This thesis project explores Chicana feminist Gloria Anzaldúa's notion of a new mestiza consciousness, in which the marginalized ethnic American woman transcends her Otherness, breaks down the borders between her different identities, and creates a Thirdspace. Through the rehearsal and performance process, three ethnic American women employed Robert Scholes' model of textuality-the consumption and production of texts-as a framework to construct a new mestiza consciousness, and create a Thirdspace. The project set to determine what strategies were significant rehearsal techniques for encouraging the cast members to exercise textual power and claim a new mestiza identity, a Thirdspace. The results reveal four overarching factors involved in assuming textual power through rehearsal and performance in the production-building trust, having appropriate skills, assuming ownership and responsibility, and overcoming performance anxiety. The discussion addresses the direct link between Thirdspace and Scholes' notion of production of original texts.

This study is a multi-method, two-city, intensive, in-depth qualitative study of Huntington's disease (HD) caregivers (HDCs) in Colombia. I explored the Colombia HDCs' experience through the Hispanic culture of caring. I develop the theory of the subrogate agency based on 5 functional stages of HD from Shoulson and Fanh (1979). This study was conducted in two different regions of Colombia, Medellin and Juan de Acosta, in which high rates of HD cases have been identified. The data were collected through three methods: (a) 56 interviews with HDCs and 8 with physicians; (b) 28 participant observations of Huntington's disease sufferers (HDSs); (c) 4 interviews and 8 focus groups of 6 members each with HDCs of late HDSs. Human agency is the ability to monitor one's own action. This study showed that the gradual and serious loss of all capabilities in HDSs has a social effect on the HDSs' agency. HDSs' survival depends on the subrogation that the HDC offers to the HDS. The HDS retains self-hood, i.e. agency, through the HDC's action. This subrogation causes a paradoxical consequence, resulting in both negative and positive effects on the caregiver. The theory of surrogate agency is supported by the data. Through the progressive …

Private property in the United States arose out of a tradition that emphasized the individual freedom to control holdings without interference from governmental influences. A sharp distinction between society as a whole and individual rights isolated ownership of private property from a notion of the common good. This dualistic framework excludes the possibility for forms of property that do not fall completely into either category. Property ownership attitudes are central to issues that often divide environmentalists and landowners. Property rights must be put in the context to understand the divergence between landowner attitudes and provisions made when the institution of private property was created. Finally, land itself as a type of property should be considered ethically distinct from other forms of property because of the interdependencies of human and nonhuman interests that the science of ecology has revealed.

This study proposed a look at the importance and challenges of knowledge management in times of great change. In order to understand the information phenomena of interest, impacts on knowledge workers and knowledge documents in times of great organizational change, the study is positioned in a major consolidation of state agencies in Texas. It pays special attention to how the changes were perceived by the knowledge workers by interviewing those that were impacted by the changes resulting from the reorganization. The overall goal is to assess knowledge management in times of great organizational change by analyzing the impact of consolidation on knowledge management in Texas's Health and Human Services agencies. The overarching research question is what happened to the knowledge management structure during this time of great change? The first research question was what was the knowledge worker environment during the time of change? The second research question was what was the knowledge management environment of the agencies during the time of change? The last research question was did consolidation of the HHS agencies diminish the ability to transition from tacit to explicit knowledge? Additionally, the study investigates how the bill that mandated the consolidation was covered in the local …

Managing water quality aspects requires the use of integrative tools that allow a holistic approach to this problem. Water quality models coupled to hydrodynamic models are these tools. This study presents the application of the water quality model WASP coupled to the hydrodynamic model DYNHYD for two distinct reservoirs: Lake Texoma and Tocoma Reservoir. Modeling the former included simulations of water velocities, water level, and four chemical and physical compounds: chlorides, dissolved oxygen (DO), biochemical oxygen demand (BOD), and total suspended solids (TSS); and validation of the results by comparing with observed values during March - May, 1997. The latter is still under project status and the simulation was performed in a prospective way. The analysis included simulations of water velocities under current and for expected conditions, DO and BOD. Both models, DYNHYD and WASP, fitted pretty well to observed conditions for Lake Texoma and for where Tocoma Reservoir has been planned. Considering management and decision support purposes, the role of boundary and loading conditions also was tested. For Lake Texoma, controlling boundary conditions for chlorides is a determinant factor for water quality of the system. However, DO and TSS in the reservoir are governed by additional process besides the …

The present study examined the perceptions of teams and managers on team potency levels as a function of stage of team development. Drawing from the power and influence literature, potency was established as a means by which to assess team's internal dynamics. Stage of team development was separated into four categories including pseudo, potential, real and high performance teams. Archival data included 45 teams and managers gathered from the manufacturing and service industries. Results indicated a significant linear relationship between team perceptions of team potency and stage of team development. Additionally, potency perceptions of teams significantly differentiated between the four stages of team development. Manager perceptions of team potency produced non-significant results. Possible explanations of the results as well as implications for practice and future research are provided.

In recent years, few laws have had greater impact on public education than Title IX of the Education Amendments of 1972. As a result of this legislation, participation levels of female athletes have risen dramatically. Conducted in the Texas Education Agency's Region XI, this study sought to ascertain the perceptions of high school principals, the lead coaches of male athletes, and the lead coaches of female athletes with regard to their schools' compliance with the components of Title IX. The study centered on the results of a survey instrument that included twenty Likert-scale questions as well as several demographic questions. The research questions sought to determine: (1) respondents' overall perception of compliance; (2) any differences in perceptions of compliance based upon the role of the individual; (3) any differences in perceptions based upon the percentage of students qualifying for free and reduced lunch; (4) any differences based upon the state classification of the schools; (5) any differences based upon the gender of respondents; (6) whether complaints filed via OCR result in a perception of increased compliance; and (7) the program component areas in which respondents view their schools to be most compliant. Descriptive and causal-comparative methods were used to analyze …

In this study the author addresses the problem of finding quality repertoire for young college-level saxophonists. By examining graded repertoire lists from a variety of college and university saxophone instructors, the author has compiled a list of 180 works for alto saxophone and piano. Twenty-four well-known works of a difficulty-level appropriate for freshman and sophomore players are identified and annotated. Each annotation consists of bibliographical information, a biographical sketch of the composer, a difficulty rating of eight elements of performance, a discussion of performance considerations, and a bibliography of available recordings. The eight elements of performance included in the difficulty rating are: Meter, key signatures, tempo, note-values, rhythm, articulation, range, and dynamic levels. Each of these facets is graded using a six-point difficulty scale. One work from the select list, Yvon Bourrel's Sonate Pour Saxophone Alto et Piano, has been analyzed in greater detail with regard to thematic material and key areas to provide in-depth information that, hopefully, will help the student gain a deeper understanding of that work and as a result perform the piece with greater artistry.

What does it take for organizations to support people working together effectively? What does it mean for an organization to be effective? Does successful collaboration lead to more effective organizations? This study explored these questions both theoretically and empirically in an effort to help organizations understand the most important aspects to consider when attempting to achieve collaboration for organization success. The purpose of this study was to fill some of the gaps in the research by taking a broad, holistic approach to exploring the context required to support collaboration at levels of organizations broader than the team and exploring the links between organization support of collaboration and organization effectiveness. In preparation for the current study, the Organization Support of Collaboration model was developed to identify the broad organization design elements that are required to support collaboration. The Organization Effectiveness model was created to provide a holistic view of what it takes for an organization to be considered effective. The present study empirically validated these models and explored the links between them. Data was collected via a web-based questionnaire administered to a broad sample of individuals who work in organizations. Results supported a model of Organization Support of Collaboration with six …
