Health Reform Implementation Analysis: A Guide to Policy Development for Geriatric Care Planning, Integration and Evaluation

In the context of health care delivery for senior citizens, this research utilizes three studies that examine the development and implementation of health policy and the factors that can directly or indirectly impact the effective delivery of health services to senior citizens. It utilizes three essays employing mixed methods (qualitative and quantitative) methods including semi structured interviews, multiple regression and partial least squares structural equation modelling to examine the extent to which the implementation of health services delivered attributes of primary and integrated care to seniors. The two essays identified methods, approaches and strategies of integrated care relevant to the development of policy that can be successfully implemented when the contextual issues that older people consider to be important in maintaining their functional capabilities and their motivation to improve health as perceived by them are addressed. Consequent upon the results from these studies, the third essay examines the methodological issues on integrated geriatric care implementation when guidelines for effective policy development identified were not followed. By highlighting the relationship between effective policy and patient satisfaction, these three essays' recommended approach enhances the theory of health design that confirms that theoretical models of primary care must incorporate the system, process and …

Smoothing the information seeking path: Removing representational obstacles in the middle-school digital library. (open access)

Smoothing the information seeking path: Removing representational obstacles in the middle-school digital library.

Middle school student's interaction within a digital library is explored. Issues of interface features used, obstacles encountered, search strategies and search techniques used, and representation obstacles are examined. A mechanism for evaluating user's descriptors is tested and effects of augmenting the system's resource descriptions with these descriptors on retrieval is explored. Transaction log data analysis (TLA) was used, with external corroborating achievement data provided by teachers. Analysis was conducted using quantitative and qualitative methods. Coding schemes for the failure analysis, search strategies and techniques analysis, as well as extent of match analysis between terms in student's questions and their search terms, and extent of match analysis between search terms and controlled vocabulary were developed. There are five chapters with twelve supporting appendixes. Chapter One presents an introduction to the problem and reviews the pilot study. Chapter Two presents the literature review and theoretical basis for the study. Chapter Three describes the research questions, hypotheses and methods. Chapter Four presents findings. Chapter Five presents a summary of the findings and their support of the hypotheses. Unanticipated findings, limitations, speculations, and areas of further research are indicated. Findings indicate that middle school users interact with the system in various sequences of patterns. …

Bayesian Probabilistic Reasoning Applied to Mathematical Epidemiology for Predictive Spatiotemporal Analysis of Infectious Diseases (open access)

Bayesian Probabilistic Reasoning Applied to Mathematical Epidemiology for Predictive Spatiotemporal Analysis of Infectious Diseases

Abstract Probabilistic reasoning under uncertainty suits well to analysis of disease dynamics. The stochastic nature of disease progression is modeled by applying the principles of Bayesian learning. Bayesian learning predicts the disease progression, including prevalence and incidence, for a geographic region and demographic composition. Public health resources, prioritized by the order of risk levels of the population, will efficiently minimize the disease spread and curtail the epidemic at the earliest. A Bayesian network representing the outbreak of influenza and pneumonia in a geographic region is ported to a newer region with different demographic composition. Upon analysis for the newer region, the corresponding prevalence of influenza and pneumonia among the different demographic subgroups is inferred for the newer region. Bayesian reasoning coupled with disease timeline is used to reverse engineer an influenza outbreak for a given geographic and demographic setting. The temporal flow of the epidemic among the different sections of the population is analyzed to identify the corresponding risk levels. In comparison to spread vaccination, prioritizing the limited vaccination resources to the higher risk groups results in relatively lower influenza prevalence. HIV incidence in Texas from 1989-2002 is analyzed using demographic based epidemic curves. Dynamic Bayesian networks are integrated with …

Culture and Anxiety: a Cross-Cultural Study (open access)

Culture and Anxiety: a Cross-Cultural Study

By measuring interactions among and between anxiety and the independent variables of country of origin, gender, level of education, and age, this study attempted to gain insight into how students from different countries experience anxiety on a U.S. college campus. Results of the Multivariate Analysis of Variance (MANOVA) and the univariate test(ANOVA) indicated that the gender and level of education of the subjects made no significant difference. However, when it came to country of origin, there were significant differences between two of the cultural groups and respective anxiety level. Findings also support a positive correlation between age and anxiety levels, with the youngest participants having the lowest anxiety levels.

Operators on Continuous Function Spaces and Weak Precompactness (open access)

Operators on Continuous Function Spaces and Weak Precompactness

If T:C(H,X)-->Y is a bounded linear operator then there exists a unique weakly regular finitely additive set function m:-->L(X,Y**) so that T(f) = ∫Hfdm. In this paper, bounded linear operators on C(H,X) are studied in terms the measure given by this representation theorem. The first chapter provides a brief history of representation theorems of these classes of operators. In the second chapter the represenation theorem used in the remainder of the paper is presented. If T is a weakly compact operator on C(H,X) with representing measure m, then m(A) is a weakly compact operator for every Borel set A. Furthermore, m is strongly bounded. Analogous statements may be made for many interesting classes of operators. In chapter III, two classes of operators, weakly precompact and QSP, are studied. Examples are provided to show that if T is weakly precompact (QSP) then m(A) need not be weakly precompact (QSP), for every Borel set A. In addition, it will be shown that weakly precompact and GSP operators need not have strongly bounded representing measures. Sufficient conditions are provided which guarantee that a weakly precompact (QSP) operator has weakly precompact (QSP) values. A sufficient condition for a weakly precomact operator to be strongly …

An investigation of the relationships between job characteristics, satisfaction, and team commitment as influenced by organization-based self-esteem within a team-based environment

Access: Use of this item is restricted to the UNT Community
Team-based management is a popular contemporary method of redesigning jobs in order to more effectively utilize the human potential of employees. The use of such management techniques should result in increased satisfaction and team commitment; however, many research studies have failed to demonstrate increases in affective outcomes on the part of the employee. The research question examined in this study is, "What specific job dimensions and situational factors result in higher levels of satisfaction and team commitment?" The Job Characteristics Model (Hackman & Oldham, 1975) provided a basis for this study. The model was designed for individual contributors and has not been extensively used in team research. As expected it was found that within a team-based environment higher levels of the five core job dimensions of skill variety, task identity, task significance, autonomy, and job feedback were associated with increased satisfaction and team commitment. Organization-based self-esteem was found to mediate the relationship between the five core job dimensions and the affective outcome variables. Contrary to expectations, however, it was found that consultative team members experienced higher levels of satisfaction and commitment than substantive team members. In addition, consultative team members reported higher levels of two core job dimensions, skill variety …

Biodiversity of Dragonflies and Damselflies (Odonata) of the South-Central Nearctic and Adjacent Neotropical Biotic Provinces (open access)

Biodiversity of Dragonflies and Damselflies (Odonata) of the South-Central Nearctic and Adjacent Neotropical Biotic Provinces

The south-central United States serves as an important biogeographical link and dispersal corridor between Nearctic and Neotropical elements of western hemisphere odonate faunas. Its species are reasonably well known because of substantial collections, but there has been no concerted effort to document the extent of biodiversity and possible geographic affinities of dragonflies and damselflies of this region. The recent discoveries of Argia leonorae Garrison, Gomphus gonzalezi Dunkle and Erpetogomphus heterodon Garrison from southern and western Texas and northern Mexico suggest that Odonata species remain to be discovered in this area, particularly from far south Texas and northern Mexico. I have documented a total of 12,515 records of Odonata found in 408 counties within the south-central U.S. A total of 73 species of damselflies and 160 species of dragonflies was revealed in the region. The 233 (197 in Texas) Odonata species are distributed among 10 families and 66 genera. Illustrated family, generic, and species-level keys are provided. Since the beginning of this work in the Fall of 1993, one species has been added each to the Louisiana and Oklahoma faunas, and 12 species have been added, previously unreported from Texas, including four new to the U.S. The area of highest Odonata …

The Effect of Average Grain Size on Polycrystalline Diamond Films (open access)

The Effect of Average Grain Size on Polycrystalline Diamond Films

The work function of hydrogen-terminated, polycrystalline diamond was studied using ultraviolet photoelectron spectroscopy. Polycrystalline diamond films were deposited onto molybdenum substrates by electrophoresis for grain sizes ranging from 0.3 to 108 microns. The work function and electron affinity were measured using 21.2 eV photons from a helium plasma source. The films were characterized by x-ray photoelectron spectroscopy to determine elemental composition and the sp2/sp3 carbon fraction. The percentage of (111) diamond was determined by x-ray diffraction, and scanning electron microscopy was performed to determine average grain size. The measured work function has a maximum of 5.1 eV at 0.3 microns, and decreases to 3.2 eV at approximately 4 microns. Then the work function increases with increasing grain size to 4.0 eV at 15 microns and then asymptotically approaches the 4.8 eV work function of single crystal diamond at 108 microns. These results are consistent with a 3-component model in which the work function is controlled by single-crystal (111) diamond at larger grain sizes, graphitic carbon at smaller grain sizes, and by the electron affinity for the intervening grain sizes.

An Investigation of the Management Accounting Framework for Performance Evaluation in American Multinational Enterprises (open access)

An Investigation of the Management Accounting Framework for Performance Evaluation in American Multinational Enterprises

The development of adequate performance evaluation techniques for appraising foreign subsidiaries and their managers in an environment different from their domestic ones has been suggested as an area where management accounting should be extended. This study concerned the performance evaluation of foreign subsidiary managers with the following objectives: (1) to examine the relationships among environmental factors and foreign subsidiary performance, (2) to develop a multinational enterprise (MNE) environmental model to evaluate the performance of subsidiary managers on the basis of controllable factors only, and (3) to test the model in American multinational enterprises for the existence of association among environmental factors and measured performance of foreign subsidiaries. The research method employed in this study was to test for association between noncontrollable environmental factors of a particular foreign country and measured performance of the foreign subsidiary (in terms of ROI) in that particular country. Major noncontrollable factor groups used were economic, political-legal, educational, and social environmental constraints.

Interfacial Characterization of Chemical Vapor Deposition (Cvd) Grown Graphene and Electrodeposited Bismuth on Ruthenium Surface (open access)

Interfacial Characterization of Chemical Vapor Deposition (Cvd) Grown Graphene and Electrodeposited Bismuth on Ruthenium Surface

Graphene receives enormous attention owing to its distinctive physical and chemical prosperities. Growing and transferring graphene to different substrates have been investigated. The graphene growing on the copper substrate has an advantage of low solubility of carbon on the copper which allow us to grow mostly monolayer graphene. Graphene sheet of few centimeters can be transferred to 300nm silicon oxide and quartz crystal pre-deposited with metal like Cu and Ru. Characterization of the graphene has been done with Raman and contact angle measurement and recently quartz crystal microbalance (QCM) has been employed. The underpotential deposition (UPD) process of Bi on Ru metal surface is studied using electrochemical quartz crystal microbalance (EQCM) and XPS techniques. Both Bi UPD and Bi bulk deposition are clearly observed on Ru in 1mM Bi (NO3)3/0.5M H2SO4. Bi monolayer coverage calculated from mass (MLMass) and from charge (MLCharge) were compared with respect to the potential scanning rates, anions and ambient controls. EQCM results indicate that Bi UPD on Ru is mostly scan rate independent but exhibits interesting difference at the slower scan. Bi UPD monolayer coverage calculated from cathodic frequency change (ΔfCathodic) is significantly smaller than the monolayer coverage derived from integrated charge under the cathodic …

Derivation of the Thematic Material and Intervallic Gestures From the Main Theme in Fantasia Carioca By Sérgio Assad (open access)

Derivation of the Thematic Material and Intervallic Gestures From the Main Theme in Fantasia Carioca By Sérgio Assad

The quantity of classical guitar literature reached a new peak late in the twentieth century with many famous guitarists publishing their own works for solo classical guitar. This increase in the published guitar literature resulted in a decline of the relative analytical discussions of contemporary guitar works. Sérgio Assad is a perfect example of an active guitarist/composer whose works are frequently performed in guitar recitals and yet very little discussion has been provided attempting to gain a deeper understanding of his compositional language. The purpose of this study is to two-fold: first, to show that Fantasia Carioca (1994) is a very carefully organized work and includes an intricate network of thematic material developed through a spectrum of intervallic gestures, of which all derive from the main theme of the piece; second, to provide a deeper insight into the compositional language of Sérgio Assad through a demonstration of different compositional procedures to which the composer resorts. This one-movement piece reveals a high level of organization present in Sérgio Assad's style. The entire thematic material is carefully derived from the main theme. Each thematic unit shows a set of predetermined characteristics that allow these units to react to particular textures and situations. …

An Analysis of Corporate Accounting and Reporting Practices in Bahrain (open access)

An Analysis of Corporate Accounting and Reporting Practices in Bahrain

The primary objective of this dissertation is to determine the factors that have shaped the corporate financial reporting practices in Bahrain. Prior researchers have offered two explanations, environmental factors and cultural importation, for the emergence of financial reporting practices in developing countries. The environmental explanation suggests that a nation's financial reporting practices will be shaped by its socioeconomic structure. The cultural importation explanation states that the desire for international legitimacy creates incentives for developing nation to adopt Western financial reporting practices. Bahrain provided an excellent environment in which to examine the two explanations since its public and closed corporations have similar economic characteristics. Only public corporations are legally required to publish financial reports. I posited that public corporations would try to gain legitimacy for their published reports by adopting Western standards, while closed corporations would not have a similar incentive. I used an interpretive framework to analyze the Bahrain socioeconomic environment and to examine the general financial reporting practices of Bahraini corporations. I found that closed corporations provided data responsive to the Bahraini environment. Public corporations, however, adopted International Accounting Standards. My analysis supported prior researchers7 findings that colonialism, the need for international legitimacy, and international audit firms were important …

Evaluation of Texas Home Instruction for Parents of Preschool Youngsters Program on Reading and Math Achievement for Grades K to 8 (open access)

Evaluation of Texas Home Instruction for Parents of Preschool Youngsters Program on Reading and Math Achievement for Grades K to 8

This study was intended to evaluate the impact of socioeconomically disadvantaged children's participation in the Texas Home Instruction for Parents of Preschool Youngsters (TX HIPPY) Program on their school readiness and academic achievement. The study used a quasi-experimental design and applied full and optimal propensity score matching (PSM) to address the evaluation concern of the impact of the TX HIPPY program on HIPPY participants' academic achievement compared to non-HIPPY participants. This evaluation targeted former HIPPY participants and tracked them in the Dallas ISD database through Grade Levels K-8. Data were obtained by administering Istation's Indicators of Progress (ISIP) for kindergarten, TerraNova/SUPERA for Grades K-2, and State of Texas Assessments of Academic Readiness for math and reading (STAAR) for Grades 3-8. HIPPY and non-HIPPY groups were matched using propensity score analysis procedures. The evaluation findings show that the TX HIPPY program positively influences kindergarten students to start school ready to learn. The findings of math and reading achievements suggest that HIPPY children scored at the same level or higher than non-HIPPY children did on math and reading achievement, indicating that TX HIPPY program has achieved its goal of helping children maintain long-term academic success. However, the evaluation findings also indicated that …

A Description and Analysis of the Channels of Distribution for Food Products in the State of Kuwait

This study is intended, first, to describe and analyze the channels of distribution for food products in the State of Kuwait, second, to pinpoint the problems that exist in the food-distribution system, and, third, to make specific recommendations for the alleviation of the problems. Consistent with the objectives of the study and based on the description and analysis of the food-distribution system in the country, it is concluded in the study that Kuwait depends on imports for virtually all of its food; the government plays a major role in the food-distribution system; and the majority of food wholesaling and retailing establishments are small, inefficient, and lack modern marketing and physical distribution techniques. Product shortages and rising food prices plague the food-distribution system in the country. Also, the findings indicate that consumers in Kuwait are generally ignorant and uninformed in the areas of food nutrition and food shopping, and the lack of standardization and grading of food products makes the shopping task of the consumer more difficult.
