Husband's and Daughter's Role Strain During Breast Cancer Hospice Patient Caregiving and Bereavement Adjustment

Husband's and Daughter's Role Strain During Breast Cancer Hospice Patient Caregiving and Bereavement Adjustment

Date: May 2000
Creator: Bernard, Lori Lynn
Description: 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

Identifying At-Risk Students: An Assessment Instrument for Distributed Learning Courses in Higher Education

Date: May 2000
Creator: Osborn, Viola
Description: 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

Date: May 2000
Creator: Floyd, James Michael
Description: 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

Improved Fabrication and Quality Control of Substrate Integrated Microelectrode Arrays

Date: May 2000
Creator: Zim, Bret E.
Description: 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

Infinite Planar Graphs

Date: May 2000
Creator: Aurand, Eric William
Description: 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

The Influence of National Standards for Early Childhood Programs on Selected Rural Settings of the Education Service Centers in East Texas

Date: May 2000
Creator: Sanders, Mary Elizabeth
Description: 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, 1987—1997

Integration of field-based analysis of plant community dynamics with quantitative analysis of landscape change in the Ray Roberts Lake area, 1987—1997

Date: May 2000
Creator: McDonough, Theresa J.
Description: 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

Internet and U.S. citizen militias

Date: May 2000
Creator: Weeber, Stan C.
Description: 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

An investigation of technical support issues influencing user satisfaction

Date: May 2000
Creator: Gutierrez, Charletta Frances
Description: 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 ...
