The Linkage Between Hospitals And Nursing Homes: Alternative Approaches To Minimizing Transaction Costs, Herng-Chia Chiu

Theses and Dissertations

Finding more efficient ways to organize and deliver medical care is a major policy and management concern in the United States. High levels of expenditures for administrative and coordinating functions are attributed to the fact that health care systems are not "seamless" and that excessive transaction or friction costs are incurred in the exchanges between providers and purchasers and among providers. Renewed interest in vertical integration as a means to addressed these problems is being explored in the empirical literature, but rigorous theory-based investigations are rare. This study is a theory-based exploration of how hospitals address the "make-or-buy" decision of …

A Generalized System Performance Model For Object-Oriented Database Applications, Ellen Moore Walk

Theses and Dissertations

Although relational database systems have met many needs in traditional business applications, such technology is inadequate for non-traditional applications such as computer-aided design, computer-aided software engineering, and knowledge bases. Object-oriented database systems (OODB) enhance the data modeling power and performance of database management systems for these applications.

Response time is an important issue facing OODB. However, standard measures of on-line transaction processing are irrelevant for OODB . Benchmarks compare alternative implementations of OODB system software, running a constant application workload. Few attempts have been made to characterize performance implications of OODB application design, given a fixed OODB and operating system …

Statistical Methods For Detecting And Characterizing Departures From Additivity In Multi-Dimensional Drug/Chemical Mixtures, Kathryn S. Dawson

Theses and Dissertations

In studies of the effects of multiple drug or chemical combinations, one goal may be to detect and characterize the interactions between the agents. The techniques currently applied to this problem have limitations when the experiments involve more than 2 agents. Certain response-surface techniques require an unrealistic number of observations for studies involving a large number of agents. Current graphical methods are impossible to use in studies of 3 or more agents. In this research two statistical techniques are described that can be applied to studies with an unlimited number of agents. In the first approach, dose combinations are collected …

The Computer Age And Planning: A Survey Of Technological Infusion, Robert Skot Bayers

Theses and Dissertations

This thesis reports on the results of a survey sent by the author to 148 local and regional planning agencies in Virginia. The mail survey of all Virginia county, city, town, and regional planning agencies showed that computers have been widely accepted and integrated into the planning workplace. Smaller agencies, and those with greater budgetary constraints have yet to realize the computer's full potential, however. The survey yielded an %84.5 total response rate, and covered hardware, software, organization and personnel, and effectiveness issues. It was based upon a similar survey administered in Arizona, New Mexico, and California five years ago. …

The Impact Of The Tau Mutation On Reproductive Function In The Golden Hamster, Eliza Leake Thomasson

Theses and Dissertations

The tau mutation affects the circadian system of the golden hamster primarily by decreasing the period of the activity cycle from 24 to 20 hours. To study the effect of this mutation on reproductive function in the golden hamster, 3 experiments have been designed. In the first experiment, wild-type and tau female hamsters will be maintained in conditions of 14:10 LD and 11.7:8.3 LD, respectively. Blood samples will be taken and analyzed by radioimmunoassay (RIA) to determine the timing of the proestrus LH surge. In the second experiment, wild-type and tau males will be transferred to shortened photoperiods of 10:14 …

Candido Portinari: Brazilian Artist As Cultural Ambassador: A Re-Examination Of The Library Of Congress Murals, Karen D. Daly

Theses and Dissertations

The artistic contributions of Portinari, and of many other Brazilian and Latin American modern artists, have not been adequately examined as part of the visual history of the twentieth century. Although by no means comprehensive, this study employs an holistic approach to re-examining Portinari's Library of Congress murals in an attempt to understand better not only these distinctive murals, but also the historical significance of this twentieth century artist.

Observations On The Serial Killer Phenomenon: An Examination Of Selected Behaviors Of The Interstate Offender Contrasted With The Intrastate Offender, Eric W. Witzig

Theses and Dissertations

The purpose of this work was to compare serial homicides committed by interstate and intrastate offenders and to determine differences in behavior between them. Knowledge of such differences would enable the trained homicide detective to structure his investigation according to the killer's inferred range of action.

This study used homicide data collected by the Violent Criminal Apprehension Program (VICAP), of the National Center for the Analysis of Violent Crime (NCAVC). VICAP's data was voluntarily submitted by investigators working at the state, local, and federal levels. The VICAP database had information on more than 804 cases of homicides committed by 241 …

Phosphorus Bearing Substrates In Ring Expansion Reactions, Bradley K. Norwood

Theses and Dissertations

A variety of substituted phosphonium salts, phosphorus ylides and phosphonates were studied to assess their utility in ring expansion reactions. The strategy involved formation of fused ring systems whose ring strain could be exploited to accomplish ring expansion to medium sized rings. β-Alkoxy vinylphosphonium salts were found to be unreactive with species such as the dimethylsulfoxonium methylide anion, Simmons-Smith type reagents. and carbenes in attempts to produce cyclopropyl phosphonium salts.

C-Alkylation of β-keto phosphorus ylides using haloalkanes bearing terminal groups that could be converted and reacted with the B-carbonyl, was also examined as a method for accessing strained rings bearing …

The Role Of Follicular Dendritic Cells In Human Immunodeficiency Virus Pathogenesis, Sonya Lynn Heath

Theses and Dissertations

Infection with Human Immunodeficiency Virus-1(HIV) results in a disease process characterized by three stages: an acute phase characterized by viremia, a clinically latent stage with little or no detection of virus in the blood, and the last stage, AIDS, which. is characterized. by marked immunodeficiency. During clinical latency, CD4+ T cells decline over a period lasting from a few to several years. Throughout this period, HIV is found trapped on the surface of follicular dendritic cells(FDC) in the germinal centers of secondary lymphoid tissues and this is the primary site of active viral replication. We hypothesize that FDC, and the …

A National Survey Of Occupational Therapists In The Public Schools: An Assessment Of Current Practice, Attitudes, And Training Needs Regarding The Transition Process For Students With Severe Disabilities, Katherine Josephine Inge

Theses and Dissertations

Because occupational therapy involvement in transition planning is a relatively new area. little was known about the characteristics of school-based therapists who serve students in this age group. The purpose of this study was to determine their current level of participation in the transition process, the roles that therapists identified for themselves in this process, their attitudes towards best practices for serving students ages 14 - 22, and occupational therapists’ future training needs if they are to participate fully in the national transition initiative. A survey was mailed to 1,000 therapists on the American Occupational Therapy Associations Direct Mail List …

Current Management Of Computerized Personnel Files In Virginia Public Schools: A Legal And Policy Analysis, Andrew Jameson Smith

Theses and Dissertations

Privacy in the workplace will be a significant legal and policy issue in employment during the late 1990's. The impact of computer technology in employment highlights privacy concerns and issues and is particularly acute in public school employment. Public schools have a right to know information about teachers which relates to their fitness in working with children. At the same time, teachers have a legitimate expectation of privacy, especially as it applies to their professional reputations and their abilities to maintain or obtain future employment in teaching.

This study had two purposes. One was to determine the extent of computer …

Prevention As A Component Of Homeless Policy: A Longer-Term Evaluation Of The State Of Virginia's Homeless Intervention Program, Emma Kathleen Flaherty

Subjects were asked to fill out a six page questionnaire immediately prior to a daylong certification training session. The sample was primarily white (85.2%) and male (57.7%). Information was gathered on the subjects' demographic characteristics, experience with and attitudes toward expert witnesses in custody cases, opinions on traditional court and family structures, and knowledge of developmental …

Role Of Perceived Competence In The Behavior Of Socially Anxious Persons In Problem-Solving Groups, Scott D. Bradshaw

Theses and Dissertations

Research finds high-shy persons participate minimally in interactions, withhold ideas from their groups, and negatively evaluate their performance. While commonly true, high-shy persons do not always interact less and it has been suggested (Efran & Korn, 1969) that high-shy persons may dominate a discussion if they can find a "safe" topic. The current study examined whether perceptions of perceived competence can produce this effect and increase the performance level of high-shy persons in a problem-solving group above the performance level of low-shy persons.

One hundred and four women, ages 18 to 24, at Virginia Commonwealth University participated. Subjects completed a …

"Writing A Picture": Adolph Gottlieb's Rolling And Yoshihara Jiro's Red Circle On Black, Ginger Suzanne Russell

Theses and Dissertations

Calligraphy and calligraphic elements in abstract art demonstrate the differences between Japanese and American approaches to abstraction. An examination of the use of calligraphy in Japanese art can reveal how its historic tradition in Japan lends depth and meaning to an image, which is not effectively possible for American artists using the same forms. These differences descend from a Japanese writing system that developed as abstracted images in themselves. Though the Western tradition of Abstract Expressionism art sought to make the experience of painting purely visual without the aid of narrative, explanation, or text, both American and Japanese artists used …

Attachment, Social Support, And Violence In Adolescent Delinquents, James R. Craft

Theses and Dissertations

Attachment relationships between children and their primary caretakers have been hypothesized to contribute to internal working models of subsequent relationships with others. Poor attachment might lead to internal working models which devalue later relationships, making the perpetration of violence against others more likely. One focus of this study was to propose a model which combined parental bonding, adolescent attachment, and perceived family support to predict the severity of violence used against others by adolescent delinquents. A second focus was to test the proposed model in predicting the total number of violent offenses committed by adolescent delinquents. One hundred and forty-five …

Determinants Of Continuity Of Care For Persons Transitioning From State Psychiatric Facilities To Communities, Sarah P. Farrell

Theses and Dissertations

When individuals with serious mental illness are discharged to the community, continuous and coordinated care are both desirable and necessary. A lack of continuity places the individual at risk for becoming lost to further services.

This study explores continuity of care for persons discharged from state psychiatric facilities in Virginia to communities. Continuity of care is defined as the successful initiation and maintenance of face-to-face contact by CSB staff with individuals to be discharged from state hospitals, and the subsequent provision of services post-discharge. This study identifies factors that influence continuity of care, examines the degree to which these factors …

"Cold Case" Investigations Within Fairfax County: Turning The Liability Of Time Into An Asset, Rodney L. Gohn

Theses and Dissertations

No department or individual involved in the investigation of homicides is ever going to have a 100% closure rate. Therefore, many departments will be faced with a situation where another homicide happens before they are finished handling the previous one.

How does one manage these open cases; how often are they reviewed; and who is responsible once the assigned detective is either transferred or leaves the unit or department? Someone has to be able to answer questions from the family, media and anyone else who might inquire about the case.

Based on the number of unsolved homicide cases within Fairfax …

The Relationship Between Physician Personality Type And Medical Malpractice Risk, Thomas H. Casey

Theses and Dissertations

The purpose of this study was to investigate possible relationships between a physician's personality type and his or her risk of receiving a medical malpractice claim or lawsuit. Patients frequently initiate a malpractice claim for reasons other than the perception of an injury. Often it is the result of a misunderstanding caused by ineffective or insufficient communication with the physician. Different personality types are known to communicate differently.

Six research questions were explored in this analytical-descriptive study. The population was the physician faculty of the Medical College of Virginia. The Myers-Briggs Type Inventory (MBTI) was completed by 236 faculty. Information …

Organizational Slack, Efficiency, And Quality Of Care In Acute Care Hospitals, Kyung Ii Youn

Theses and Dissertations

The relationship between technical efficiency and quality of care in hospitals is studied in the context of resource availability in hospital organizations. The resource availability of hospitals is conceptualized by organizational slack.

An integrated model is developed encompassing the source of organizational slack, its impact on technical efficiency and on quality of care, and its impact on the relationship between efficiency and quality. Organizational threat as an environmental factor affecting the level of slack is measured by the level of competition and regulation. Organizational slack is measured using financial and operational indicators of the hospitals. Technical efficiency is estimated by …

Nmda Receptor-Mediated Synaptic Plasticity In Developing Mammalian Visual Pathways, Gregory S. Perens

Theses and Dissertations

Precise connections in many mammalian nervous systems require a great deal of remodeling during development. In the visual system, many excess synapses are originally formed in the lateral geniculate nucleus and striate cortex. Only the correct set of axon terminals are retained during normal development, while imprecise ones withdraw. The mechanism by which only correct axons are retained requires neural activity, and may be regulated by specific receptors at synapses.

The transmission of neural signals at these synapses is carried out in part by the glutamate-activated NMDA receptor. It is hypothesized that NMDA receptor activation plays a crucial role in …
