Millage Election Outcomes In Michigan Public School Districts: A Test Of The Rational Choice And Social Psychological Voting Models, Christopher Petras

Dissertations

In this study, the author tests two models of voting behavior to predict the likelihood of a public school millage passing. They are: (1) a rational-choice model, and (2) a social psychological model. The rational-choice model asserts that the likelihood of a school millage passing is a function of the millage's economic benefit as perceived by the voter. The social psychological model asserts that support for the local school millage is a function o f the voter's political attitudes and/or the salience of the ballot issue.

The author analyzed every millage election in the 561 (K-12) Michigan public school districts …

The Association Of Five Therapist Characteristics With Therapists' Suspicion Of Childhood Sexual Abuse In Adult Client Cases, Sherri I. Terrell

Dissertations

One hundred and twenty-five doctoral level psychologists interning at university counseling centers throughout North America were surveyed to explore the association of therapists' suspicion of childhood sexual abuse (CSA) in adult client cases with five therapist characteristics: (a) gender; (b) having or not having had personal therapy; (c) having or not having professional experience with three or more clients who are survivors of CSA; (d) having or not having a close friend, family member, or significant other who is a survivor of CSA; and (e) being or not being a survivor of CSA.

Information was collected on interns' demographics and …

Reductive Dehalogenation Of Chlorinated Aromatic And Aliphatic Hydrocarbons Under Anaerobic Conditions, Monica Turner Togna

Dissertations

The process of reductive dehalogenation involves the removal of a halogen substituent from a molecule with the concurrent addition of electrons to the molecule, resulting in a more reduced and often less toxic product. Anaerobic bacteria have the potential to utilize hazardous chlorinated aromatic and aliphatic hydrocarbons as electron acceptors in metabolic reductive dehalogenation processes.

In experiments performed with chlorinated aromatic compounds a highly enriched anaerobic culture stoichiometrically converted 2,4,6-trichlorophenol (2,4,6-TCP) to 4-monochlorophenol. Dehalogenation occurred only in alkaline media (pH 8-9) at concentrations of 2,4,6-TCP up to 1 mM. Data indicated that the dehalogenating organism did not fit into any …

Scaling Up Of Water-Based Organic Reactions, Chen Gu

Dissertations

Three water-based organic reactions, Diels-Alder, epoxidation of olefins, and free-radical bromination have been investigated as an approach to pollution prevention. The first two systems were scaled-up by at least a factor of 20. These reactions are of special interest to the pharmaceutical and speciality chemical industries. The photo-induced free-radical bromination of alkanes with bromine in water was studied in a two-phase system. Experimental results show that all reactions have advantages resulting from being conducted in water, such as reaction rate acceleration, reaction selectivity increase, and the absorption of water-soluble gas byproduct by solvent water.

The effects of stirring rates, temperature, …

Effect Of Vitamin Supplementation On Biodegradation Of Aliphatic Hydrocarbons And Diesel Fuel, Susmita Guptapal

Dissertations

Bioremediation of hazardous wastes is proven to be environmentally benign and most cost effective technology when proper conditions are provided. However, commercialization of this method still requires comprehensive research to enhance the degradation rate to make the technology more acceptable for implementation. In this research a unique approach to increase the rate of biodegradation by vitamins supplementation was studied.

Five vitamins, niacin, biotin, folic acid, thiamin and pantothenic acid were selected for the present study. Different short chain (C₈ and C₉), and long chain (C₁₆ and C₁₇) aliphatic hydrocarbons and diesel fuel (a mixture …

At first, based on the detailed survey on the piezo-optic properties of the crystals used in microelectronics, we apply …

Behavior And Attitudes Related To The Prevention Of Sexually Transmitted Disease And Unplanned Pregnancy, J. Lee Hoover

Dissertations

A sample of 214 persons was tested to determine the impact of gender role orientation, neuroticism, extraversion, authoritarianism, race, gender, and sexual orientation on attitudes and behavior relevant to the prevention of sexually transmitted disease and unintended pregnancy. Specifically measured was the impact of these factors on attitudes toward the condom as contraceptive, attitudes toward the condom as prophylactic, and reported condom use.

Gender role orientation was measured using the short form of the Bern Sex Role Inventory (BSRI) (Bern, 1978), neuroticism and extraversion were measured using the NEO-Five Factor Inventory (NEO-FFI) (Costa & McCrae, 1992), and authoritarianism was measured …

Leader Attitudes And Leader Stress: Is There A Connection?, Earl B. Kaurala

Dissertations

In an era of technological innovation, information explosion, and state and national calls for educational reform, it seems important to adopt processes that will allow for rapid diffusion of knowledge and implementation of new technologies into classrooms. The leadership provided by the principal is extremely important to this process. Unfortunately, principals can be overwhelmed by the conflicting expectations that have become associated with their role within the educational community.

The purpose of this study was to investigate the leadership attitudes of Michigan secondary school principals and the relationship of these attitudes to the work-related stress the surveyed principals indicated they …

Children With Hiv: How They Feel About What Parents Say, Susan Pease Instone Dnsc, Msn, Cpnp

Dissertations

With improvements in diagnosis and care, children with HIV infection are living long enough to reach school age, a stage when they are capable of perceiving the stigmatizing, life-threatening nature of their illness. Many parents desire to protect them from this knowledge by avoiding an open dialogue about their disease, even though pediatric professionals advocate disclosure. Research-based guidelines about the risks and benefits of telling, however, have not been available in the literature. Using an innovative, qualitative approach through the use of grounded theory and projective drawing techniques, this investigation sought to explore what parents said about the illness and …

Explicit Congestion Control Algorithms For Available Bit Rate Services In Asynchronous Transfer Mode Networks, Ambalavanar Arulambalam

Dissertations

Congestion control of available bit rate (ABR) services in asynchronous transfer mode (ATM) networks has been the recent focus of the ATM Forum. The focus of this dissertation is to study the impact of queueing disciplines on ABR service congestion control, and to develop an explicit rate control algorithm.

Two queueing disciplines, namely, First-In-First-Out (FIFO) and per-VC (virtual connection) queueing, are examined. Performance in terms of fairness, throughput, cell loss rate, buffer size and network utilization are benchmarked via extensive simulations. Implementation complexity analysis and trade-offs associated with each queueing implementation are addressed. Contrary to the common belief, our investigation …

Development Of A Traffic Safety Index For Urban Intersections, Jae-Hong Kang

Dissertations

Conventional safety analysis focuses on the accident environment at specific locations or a limited segment of highways or arterials, and attempts to identify the effects of accident contributing factors. The development of a safety index in the past was based on a statistical summary for county or statewide areas, using general indicators such as population, number of registered vehicles, vehicle miles traveled and so on. This research effort presents a state-of-the-art procedural analytical approach for the safety analysis of Manhattan intersections that are exposed to a unique urban environment. The computed index provides safety ratings that can identify potential safety …
