Husband's and Daughter's Role Strain During Breast Cancer Hospice Patient Caregiving and Bereavement Adjustment
Current literature regarding caregiver bereavement adjustment has advanced two competing models explaining adjustment in relation to caregiver interrole conflict: the Relief Model and Complicated Grief Model. This research has primarily focused on the experience of those providing care to dementia patients. This study tests these competing models of bereavement adjustment for husband and daughter caregivers of breast cancer hospice patients. For husbands, greater psychological strain and health strain were predictive of greater difficulty with bereavement adjustment, supporting the Complicated Grief Model of bereavement adjustment. For daughters, strain was not a significant predictor of bereavement adjustment, and thus did not support either bereavement adjustment model. While daughter caregivers experienced more role strain than husband caregivers during patient care, the degree of role strain was predictive of bereavement adjustment for husbands but not for daughters, suggesting that relationship type (husbands versus daughters) between caregiver and patient impacts which factors influence bereavement adjustment.

Identifying At-Risk Students: An Assessment Instrument for Distributed Learning Courses in Higher Education
The current period of rapid technological change, particularly in the area of mediated communication, has combined with new philosophies of education and market forces to bring upheaval to the realm of higher education. Technical capabilities exceed our knowledge of whether expenditures on hardware and software lead to corresponding gains in student learning. Educators do not yet possess sophisticated assessments of what we may be gaining or losing as we widen the scope of distributed learning. The purpose of this study was not to draw sweeping conclusions with respect to the costs or benefits of technology in education. The researcher focused on a single issue involved in educational quality: assessing the ability of a student to complete a course. Previous research in this area indicates that attrition rates are often higher in distributed learning environments. Educators and students may benefit from a reliable instrument to identify those students who may encounter difficulty in these learning situations. This study is aligned with research focused on the individual engaged in seeking information, assisted or hindered by the capabilities of the computer information systems that create and provide access to information. Specifically, the study focused on the indicators of completion for students enrolled in …

Images of Remembered Earth
Images of Remembered Earth is a musical composition scored for full orchestra. The composition was inspired by Georgia O'Keeffe's painting, Light Coming on the Plains I (1917), which depicts a sunrise over a flat and empty landscape. In the painting, the expanse of the sun's rays is expressed through an even-blended transformation of color from goldish-blue at the light's source to progressively darker shades of blue near the edges of the canvas. The progression of color is interrupted by thin gold bands which sectionalize the sunrise into seven concentric arches. The construction of the musical composition derives musical materials directly from elements found within O'Keeffe's painting, specifically the shaping of structure, expansion, and color in arch patterns. Arch patterns, an integral element in O'Keeffe's painting, govern elements in the musical composition, including pitch selection, the overall tempo scheme, rhythmic activity, and formal shape. Pitch materials are expansive by design; this expansive quality is exhibited through the employment of wedge-shaped musical ideas and through the utilization of higher and lower registers. O'Keeffe's use of color in the painting influenced the orchestration of the music and is manifested in two ways: 1) gradual transformation of timbral colors and 2) the juxtaposition of …

Improved Fabrication and Quality Control of Substrate Integrated Microelectrode Arrays
Spontaneously active monolayer neuronal networks cultured on photoetched multimicroelectrode plates (MMEPs) offer great potential for use in studying neuronal networks. However, there are many problems associated with frequent, long-term use of MMEPs. The major problems include (1) polysiloxane insulation deterioration and breakdown, (2) and loss of gold at the gold electroplated indium-tin oxide (ITO) electrodes. The objective of this investigation was to correct these major problems. Quality control measures were employed to monitor MMEP fabrication variables. The phenotypes of polysiloxane degradation were identified and classified. Factors that were found to contribute most to insulation deterioration were (1) moisture contamination during MMEP insulation, (2) loss of the quartz barrier layer from excessive exposure to basic solutions, and (3) repetitive use in culture. As a result, the insulation equipment and methods were modified to control moisture-dependent insulation deterioration, and the KOH reprocessing solution was replaced with tetramethylguanidine to prevent damage to the quartz. The problems associated with gold electroplating were solved via the addition of a pulsed-DC application of gold in a new citrate buffered electroplating solution.

Infinite Planar Graphs
How many equivalence classes of geodesic rays does a graph contain? How many bounded automorphisms does a planar graph have? Neimayer and Watkins studied these two questions and answered them for a certain class of graphs. Using the concept of excess of a vertex, the class of graphs that Neimayer and Watkins studied are extended to include graphs with positive excess at each vertex. The results of this paper show that there are an uncountable number of geodesic fibers for graphs in this extended class and that for any graph in this extended class the only bounded automorphism is the identity automorphism.

The Influence of National Standards for Early Childhood Programs on Selected Rural Settings of the Education Service Centers in East Texas
This study addressed the current status of early childhood curriculum design and implementation in the Texas Education Service Centers Seven and Eight. No Previous research about the characteristics of the preschool programs had been completed in those areas. This research established if preschool programs were receiving priority status in East Texas. The results yielded evidence regarding the characteristics of administrators, teachers, curriculum implementation, plus parent and community involvement. The information also provided insight regarding short-term and longitudinal effects on children who have attended preschool programs. Data were collected from a search of educational literature, regional service preschool directors, administrators, and teachers. The procedure used in designing the survey and interview documents was Michael Scriven's goal-free strategy. The main sources for the questions were the National Association for the Education of Young Children and Head Start. The study first directs attention to the common characteristics of national programs/standards, then discusses the level of implementation in local rural prekindergartens. The fifteen open-ended interviews yielded concise information relevant to the population of students served and administrative beliefs on current practices. Surveys were sent to a total of all preschool administrators in the Education Service Center Regions of Seven and Eight. A 51 percent …

Integration of field-based analysis of plant community dynamics with quantitative analysis of landscape change in the Ray Roberts Lake area, 19871997
This study focused on the effectiveness of integrating traditional plant community analyses with landscape ecological analyses based on remotely sensed data. A temporal analysis of plant community diversity was conducted for major plant communities of the Ray Roberts Lake area using transect monitoring data collected between 1987 and 1997. Landscape analyses were performed with FRAGSTATS*ARC using classified SPOT satellite imagery for 1987 and 1997. Although the methodology developed in this work was exploratory, it was found that characterizing the dynamics of major plant communities in the study area produced a more effective and insightful analysis of Ray Roberts Lake area landscape dynamics.

Internet and U.S. citizen militias
Smelser's theory of collective behavior holds that people join radical social movements because they experience strain. Among the most serious strains are anxieties that relate to one's social status and the roles that correspond to it. A social movement arises as a means of coping with these anxieties. Militia presence and activity on the Internet (especially Usenet) is a phenomenon that can be studied within the framework of Smelser's theory. Militia watchers contend that those who join the militias have experienced the kinds of strain to which Smelser refers. A content analysis of Internet traffic of U.S. militias provides a test of the general thesis outlined above. By analyzing Internet sites it is possible to examine whether militiamen have experienced strain, and whether the strain, together with other factors, influence an individual's decision to join the militia. This dissertation was the first sociological study of American militias on the Internet and the first in which militias from all regions of the country was studied. Information was gathered on 171 militiamen who joined 28 militias. A qualitative analysis of militia web sites and Usenet traffic (n=1,189 online documents) yielded answers to seven research questions. Most militiamen studied experienced some form of …

An investigation of technical support issues influencing user satisfaction
The widespread distribution of personal computers (PCs) throughout organizations has made a substantial impact on information systems. Additionally, the tremendous growth of the Internet has changed the way business is carried out. As the user population evolves into a much more technical and demanding group, their needs are also changing. With this change, Management Information Systems (MIS) departments must develop new ways of providing service and support to the user community. This study investigates the relationship between information systems support structures, support services, service quality and the characteristics of a diverse user population. This includes investigating technical support issues influencing user satisfaction. This study attempts to improve the understanding of the support function within MIS. The results of this study clarify the support needs of the users and identify user satisfaction factors, as well as factors relative to the quality of the support received. Six streams of prior research were reviewed when developing the research framework. These include: user support, end users and end-user computing, identifying and classifying user types, information centers, user satisfaction, service quality and other sources of computer support. A survey instrument was designed using the (UIS) user satisfaction instrument developed by Doll and Torkzadeh (1988) and …

Korean Electoral Behavior: The 1992 and 1997 Presidential Elections
This is a study of Korean presidential elections. Its purpose is to determine how Koreans voted in the 1992 and 1997 presidential elections and to examine the factors that contributed to winners. In addition, the study compares the two elections by developing three models: candidate choice, voter turnout and political interest models. Using post election data from the Korean Social Science Data Center a multinomial logit regression was used in the candidate choice model. It shows that Korean voters selected their candidates mainly in terms of interest in the elections, age, orientation toward the governing or opposition parties, the regional effects of the Southwest (Honam) and the Southeast (Youngnam), and the evaluation of merged parties in 1992 or a united candidacy of parties in 1997. A Monte Carlo simulation was also employed to test the traditional assumption of candidate strength. It indicates that Kim Young-Sam had a more cohesive support from his older supporters in the 1992 election while Kim Dae-Jung had a greater cohesive support from his older supporters in the 1997 election. Both Kim Young-Sam's and Kim Dae-Jung's loyalists were crucial to the winning candidates in the 1992 and 1997 elections respectively. How did people vote? To address …

Learner-Centered Teacher Beliefs and Student-Perceived Teaching Effectiveness
Following Barr and Tagg's formalization of the concept of learner-centered educational practice at the postsecondary level as described in their seminal article in Change in 1995, survey instruments have been developed to assess teachers' beliefs about their own learner-centeredness.. The research reported in this dissertation examined the connection between college students' perceptions of teacher effectiveness on each of four dimensions appearing as questions on the IDEA Survey of student reaction to instruction and courses (developed at the IDEA Center, Kansas State University, in the early 1970s) and the Assessment of Learner-Centered Practices (ALCP): Beliefs Portion of the Postsecondary Level Instructor Survey, College Level (developed in early 1999 by B. L. McCombs, University of Denver Research Institute; alpha reliabilities reported). Using scoring rubrics accompanying the ALCP instrument, instructors were identified as learner-centered or non-learner-centered based on their responses. Independent t-tests were performed to determine whether learner-centered instructors were perceived differently by students in terms of teaching effectiveness than non-learner-centered instructors on each of four dimensions: overall excellence of course, overall excellence of instructor, effectiveness of instructor in helping students achieve relevant objectives in the course, and effectiveness of course and instructor in improving students' attitude toward the field of study. Students …

Linearity and monotonicity of a 10-bit, 125 MHz, segmented current steering digital to analog converter
The purpose of this research is to determine the linearity and monotonicity of the THS5651IDW digital to analog converter (DAC), a prototype of the future Texas Instruments TLV5651, 10-bit, 125 MHz communication DAC. Testing was conducted at the Texas Instruments facility on Forest Lane, Dallas, Texas. Texas Instruments provided test equipment, software and laboratory space to obtain test data. Analysis of the data found the DAC to be monotonic since the magnitude of the differential nonlinearity (DNL) was less than ± 1 least significant bit (LSB) and the integral nonlinearity (INL) was less than ± 0.5 LSB. The study also showed that the DAC has primarily negative DNL although the DNL is well within the desired specification.

Long-Term Care Administrator Licensure and Certification: An Emerging Health Profession
Access:
Use of this item is restricted to the UNT Community
The long-term care administrator profession is one that is both new and evolving. The unique historical perspective of this health profession is brief in the number of years it encompasses and crucial in understanding the current issues facing the profession. Administrator experiences provide a point of reference regarding the profession's structural problems. Ethical considerations play a dynamic role in administrators' daily jobs as well as their continued licensure. The significance of the profession's ongoing problems at the state and national level causes the need for alternatives to the current system. A combination of these alternatives must be embraced to assist in the recruitment and retention of long-term care administrators.

Macroinvertebrate Community Structure as an Indicator of Watershed Health in the Upper Trinity River Basin, North Central Texas
Access:
Use of this item is restricted to the UNT Community
This study describes macroinvertebrate community structure and assesses its potential in detecting point and non-point sources of disturbance associated with rural and urban areas in the Upper Trinity River Basin. Geospatial techniques were used to quantify landuse within the watershed in a GIS. At rural sites near the headwaters of the Trinity River, collector-gathering burrowers that are adapted to minimal flow comprised the majority of taxa. Destinies of taxa compositions at downstream sites increased and shifted toward psammophilic and rheophilic invertebrates, including primarily collector-filtering clingers, that are characteristic of shifting sand habitats in large prairie rivers. Benthic community structure generally benefited from point source impacts including wastewater treatment plant effluents that maintained higher flow. Community indices were negatively associated with forest landuse and positively associated with urban landuse. Partial CCA determined that flow and landuse contributed equally to species dispersions. Comparisons with historical biomonitoring studies in upper Trinity River Basin indicate improved watershed health.

Market valuation of the translation process under SFAS No. 52: Further evidence
This research investigates the information content of the translation information resulting from exchange rate fluctuations. Two hypotheses are examined. The dollar movement hypotheses investigate whether there is a positive relationship between security valuation and the translation information and whether the market assigns different weights to translation gains and losses in both the depreciating and appreciating exchange rate environments. The geographic concentration hypothesis tests whether the market's response to the translation information is geographically sensitive. Prior research on SFAS No. 8 and SFAS No. 52 has concentrated on the price and trading volume responses to the deliberations and issuance of these two accounting statements. Soo and Soo (1994) examine the long-term effect of the disclosure requirement under SFAS No. 52 on MNEs' security prices from 1981 to 1987. However, they fail to address two important issues pertinent to the MNE research--the effects of exchange rate changes and the geographic concentration. The dollar movement hypotheses provide strong evidence that under both the appreciating and depreciating exchange rate environments, a positive relationship exists between security returns and the translation information when MNEs disclose translation losses in stockholders' equity. The findings also provide evidence for a positive or at least non-negative relationship between security …

The Meaning of Elder Abuse
Access:
Use of this item is restricted to the UNT Community
Elder abuse first received national attention in 1980, as the subject of a congressional investigation. Now, 20 years later, establishing successful strategies of identification, subsequent intervention, and prevention of abuse is of paramount importance; but progress toward this goal is hindered by lack of consensus as to the definition of elder abuse, and the use of vague, confusing, and sometimes contradictory terms in its discussion. In this paper, both social research and professional approaches and legal approaches to the definition of elder abuse are surveyed, as are definitions formulated for the National Elder Abuse Incidence Study conducted by the National Center on Elder Abuse. The continuing need for a universal or standard definition is emphasized.

Measuring attention: An evaluation of the Search and Cancellation of Ascending Numbers (SCAN) and the short form of the Test of Attentional and Interpersonal Style (TAIS)
This study found a relationship between the Search and Cancellation of Ascending Numbers (SCAN), Digit Span, and Visual Search and Attention Test (VSAT). Data suggest the measures represent a common construct interpreted to be attention. An auditory distracter condition of the SCAN did not distract participants, while the measure exhibited ample alternate forms reliability. The study also found that the Test of Attentional and Interpersonal Style (TAIS) short form poorly predicted performance on the Digit Span, VSAT, and SCAN. Although the TAIS exhibited good internal consistency, the items likely measure the subjective perception of attention. Furthermore, discriminant and convergent validity of the TAIS were found to be poor.

MEDLINE Metric: A method to assess medical students' MEDLINE search effectiveness
Medical educators advocate the need for medical students to acquire information management skills, including the ability to search the MEDLINE database. There has been no published validated method available to use for assessing medical students' MEDLINE information retrieval skills. This research proposes and evaluates a method, designed as the MEDLINE Metric, for assessing medical students' search skills. MEDLINE Metric consists of: (a) the development, by experts, of realistic clinical scenarios that include highly constructed search questions designed to test defined search skills; (b) timed tasks (searches) completed by subjects; (c) the evaluation of search results; and (d) instructive feedback. A goal is to offer medical educators a valid, reliable, and feasible way to judge mastery of information searching skill by measuring results (search retrieval) rather than process (search behavior) or cognition (knowledge about searching). Following a documented procedure for test development, search specialists and medical content experts formulated six clinical search scenarios and questions. One hundred and forty-five subjects completed the six-item test under timed conditions. Subjects represented a wide range of MEDLINE search expertise. One hundred twenty complete cases were used, representing 53 second-year medical students (44%), 47 fourth-year medical students (39%), and 20 medical librarians (17%). Data related …

Microstructure and Electronic Structures of Er-Doped Si Nano-particles Synthesized by Vapor Phase Pyrolysis
Access:
Use of this item is restricted to the UNT Community
Si nanoparticles are new prospective optoelectronic materials. Unlike bulk Si cry-stals, Si nanoparticles display intriguing room-temperature photoluminescence. A major challenge in the fabrication of Si nanoparticles is the control of their size distribution. The rare-earth element Er has unique photo emission properties, including low pumping power, and a temperature independent, sharp spectrum. The emission wavelength matches the transmission window of optical fibers used in the telecommunications industry. Therefore, the study of Er-doped Si nanoparticles may have practical significance. The goals of the research described in this dissertation are to investigate vapor phase pyrolysis methods and to characterize the microstructure and associated defects, particles size distributions and photoluminescence efficiencies of doped and undoped Si nanoparticles using analytical transmission electron microscopy, high resolution electron microscopy, and optical spectroscopy. Er-doped and undoped Si nanoparticles were synthesized via vapor-phase pyrolysis of disilane at Texas Christian University. To achieve monodisperse size distributions, a process with fast nucleation and slow growth was employed. Disilane was diluted to 0.48% with helium. A horizontal pyrolysis oven was maintained at a temperature of 1000 °C. The oven length was varied from 1.5 cm to 6.0 cm to investigate the influence of oven length on the properties of the nanoparticles. …
