Ranging Patterns And Habitat Utilization Of Northern River Otters, Lontra Canadensis, In Missouri: Implications For The Conservation Of A Reintroduced Species, Deborah Dorothy Boege-Tobin

Dissertations

I studied the spacing patterns and habitat utilization by reintroduced northern river otters, Lontra canadensis, at two sites in Missouri because previous studies of otters indicate, plasticity of a species social structure will likely be due to the tactics employed in acquiring resources in any given area. Seven hypotheses were tested by employing radio-tracking, habitat assessment and geographic information system approaches: (1) home range (HR) and core area (CA) size differ by sex; (2) HR and CA size differ in breeding vs. non-breeding seasons; (3) percent range overlap differs by sex; (4) habitat utilization, as indicated by latrine use, …

An Examination Of The Psychometric Properties Of The Spiritual Well-Being Scale In A Sample Of African American Women, Mary Catherine Dugan

Dissertations

This dissertation is an investigation of the psychometric properties of the Spiritual Well-Being Scale (SWBS) (Paloutzian & Ellison) using a sample of African American women recruited from the community. The purpose was to determine the appropriateness of using the SWBS with a sample not included in the earlier norming studies (Ledbetter et al., 1991). The sample consisted of 168 African American women who were parents or guardians of youth attending middle school in a Midwestern urban area. The women completed a survey including demographic information, parent scales, and the SWBS. Construct validity of the SWBS was examined by conducting a …

Increasing Blood Glucose Monitoring In Adolescents With Type 1 Diabetes: Effects Of A Prompt, Stephen J. Albrecht

Dissertations

A series of single-subject designs (AB, ABAB) were used to assess the effects of an antecedent prompting procedure (i.e., prompts) on blood glucose monitoring in young individuals diagnosed with type I diabetes. Prompts were delivered through portable, automated paging technology. Frequency of blood glucose checks was obtained across meter, baseline, and intervention phases. Metabolic control was assessed by obtaining blood glucose levels for each check across baseline and intervention phases, and hemoglobin (HbA1c) values at study entry and follow-up. Results indicated that the prompt increased blood glucose monitoring for three participants, and metabolic control improved for 2 participants when the …

Teacher Quality And Teacher Preparedness In Public Secondary Schools: Evidence From Sass 1999-2000, Xuejin Lu

Dissertations

Resource equalization represents the historical and theoretical basis for American school finance and its ideals continue to dominate discussion and practice. During the last decade and a half, the national aspiration for equitable distribution of school finance resources has started a transformation into a derivative notion of adequacy. This equity policy derivative embraces the idea of sufficiency, which in turn implies a standard. The concept of educational adequacy has grown to mean the achievement of high absolute standards. Equity (equalization) theorists measure resource level on a relative basis; each student relative to all others. Adequacy adherents measure student achievement against …

Higher Education Attorneys’ Perceptions Regarding Academic Freedom And Challenges To Academic Freedom, Manuel R. Rupe

Dissertations

Higher education attorneys have emerged in recent years as integral participants in the decision and policymaking processes within American higher educationinstitutions. The perceptions of higher education attorneys regarding academic freedom, including professorial, institutional, and student academic freedom, may significantly impact how higher education institutions respond to modern challenges to such freedom. Key challenges to academic freedom as identified in the literature were categorized into four groups for this study (a) judicial or governmental challenges, (b) internal or collegial challenges, (c) institutionalchallenges, and (d) outside or extra-institutional challenges.

An Internet-based survey was sent to higher education attorneys who subscribed to the …

Participants completed a battery of self-report measures that assessed childhood sexual abuse (CSA), adult sexual victimization (ASV), characteristics of the abuse, coping methods, PTSD symptomatology, and psychological distress. One-way analysis of variance (ANOVA) procedures revealed that victims were significantly more distressed than nonvictims; revictimized women and multiple victims were significantly more distressed than nonvictims; revictimized women were significantly more distressed than single victims; differences between multiple and single victims and single victims and nonvictims were not significant. Multivariate analysis of variance (MANOVA) analyses indicated victims reported significantly more frequent …

An Empirical Study Of Fiscal Decentralization Of Local Governments In China, Jianfeng Wang

Dissertations

The world is experiencing dramatic fiscal reconstruction in the socialist and (former) socialist countries and of continuing and fascinating evolution of government structure elsewhere. Being one of the fastest growing economies over the past nearly three decades, China seems deeply embracing this global mantra of power devolution in her effort to energize local economy that was suffocated in the highly constricted state-planning system. The literature of the Chinese central-local studies suggests that fiscal decentralization from the central government to provincial governments is a key institutional factor to explain Chinese economic success. However, the literature misses various lower levels of government …

This study examined whether professional role complexities existed for certified athletic trainers (ATCs) employed at the collegiate level, and if so, what impact these role complexities had upon job satisfaction and intent to leave a current position or the profession. The amount and sources of role complexities were examined for collegiate ATCs who were employed in clinical, faculty, or joint appointment positions.

Potential for professional role complexities exist in any situation where multiple role obligations are present in the workplace. Professional role complexities for health care employees often manifest into tension, dissatisfaction, lack of energy or ambition, and decreased attention …

Automotive Service Technology Intersectional Skills Proficiency Assessment, David L. Macquarrie

Dissertations

This dissertation focused on the creation and validation of a criterion referenced credentialing assessment of automotive service technicians' intersectional skills (ASTIS) proficiency. These intersectional skills are prerequisite and common to multiple job level tasks that an automotive service technician (AST) performs on the job. An assessment of the ASTIS was created to aid automotive technician employers in the evaluation of hiring prospective technician employees and is not duplicated by current certifications (e.g. ASE) as they do not uniquely assess these skills.

This dissertation focused on the ASTIS skills and the information an employer can obtain pertaining to a prospective employee's …

Performance Evaluation Models For Strategic Decision-Making: Towards A Hybrid Model, Geraldina Villalobos Quezada

Dissertations

Performance management systems serve strategic, administrative, and developmental purposes; therefore, their role in an organization cannot be overestimated. As a function of this strategic role, different evaluation models have been developed and implemented by organizations: BSC, CIPP, TQM, Six Sigma, and AOP.

Following a review of current evaluation theory and practice models that focus on improving strategic decision-making in organizations, four research questions were developed that sought to identify the interrelationships, evaluation components, evaluation indicators, data collected to support the evaluation,evaluation implementation protocols, quantitative and qualitative analyses, outcomes, and critical factors of the BSC and CIPP models.

Capacitated And Uncapacitated Facilities Locationallocation Problem With Sensitive Prices, Stochastic Demands, And Inventory, Yaser Al-Alawi

Dissertations

This study developed a quantitative model that solves a facility locationallocation (LA) problem that maximizes the net profits generated from expected sales. The model was formulated to take into consideration demand uncertainty, sensitive prices, and existence of inventory for capacitated and uncapacitated facilities. Four new models for the LA problem with stochastic demands and inventory were developed and studied. The four models were combinations of capacitated and uncapacitated facilities and sensitive and insensitive prices.

A new method was proposed for achieving optimality, and an approximation procedure was developed that could find near-optimal solutions for problems that could not be solved …

A Sociological History Of Prison Privatization In The Contemporary United States, Donna Selman-Killingbeck

Dissertations

This dissertation is framed by the radical criminological-theoretical perspective and utilizes the social constructionist method of analysis to examine the development of prison privatization in the United States. Central to this analysis is the question: How is it that, given the disastrous history of blatant attempts to blend capitalism and punishment, contemporary privatization of prisons not only emerged but continues to expand becoming a multinational incarceration industry? Three phases of privatization: emergence, maintenance and perpetuation, are illuminated in their political, economic and cultural contexts. Thestrategies and techniques, access to power, claims-making and managing counterclaims for example, of various stakeholders in …

Being Whole: Aligning Personhoods To Achieve Successful Childbirth With A History Of Childhood Sexual Abuse During Perinatal Services, Karla Kendall Richmond Phd, Msn, Rnc, Cns

Dissertations

Being a pregnant female is a temporary condition. A woman with a history of childhood sexual abuse aligns the personhoods of child victim, adult survivor and pregnant female to achieve a successful pregnancy, labor, delivery and postpartum experience. Female survivors desire to be recognized and function as whole being during the perinatal experience. It is estimated that 15 to 32 percent of females prior to the age of eighteen have unwanted sexual contact. Female survivors carry this history of childhood sexual abuse (CSA) with them throughout their lives which may involve childbirth. There are many long-term psychological consequences that can …

Hacks, Cracks, And Crime: An Examination Of The Subculture And Social Organization Of Computer Hackers, Thomas Jeffrey Holt

Dissertations

This dissertation examines both the subculture and social organization practices of computer hackers. The concept of normative orders (Herbert, 1998: 347) is used to explore hacker subculture in different contexts. To assess hacker social organization, I use Best and Luckenbill¿s (1994) framework of organizational sophistication as well as measures from Decker et al. (1998). The relationships between subculture, social organization, and behavior are explored as well. I collected three qualitative data sets to explore these issues, including posts from six on-line hacker discussion forums, in-depth interviews with active hackers, and field observations at the Defcon 12 hacker convention. These data …

Chronically Ill Adolescents' Involvement In Health Treatment Decision Making, Edna B. Domingo Phd

Dissertations

The purposes of this study were to explore preferences for involvement of chronically ill adolescents in health treatment decision-making; describe, explain and predict relationships and differences in self-confidence in decision-making between older and younger chronically ill adolescents; and explore relationships between severity of symptoms and self-confidence in health treatment decision-making among chronically ill adolescents. Ten to twenty million American children have some type of chronic illnesses with 90% survival to adulthood. There is lack of current literature on adolescent preferences for involvement in health care decisions. Courts and legislators assume that minors lack the requisite capacity for information, and lack …

Psychosocial Responses By Adolescent Male Victims To Peer Bullying, Karin Eve Reuter-Rice Phd

Bullying remains a pervasive problem in most schools throughout the nation. Peer-bullied victims report higher levels of depression, suicidal ideation, anxiety, and concerns regarding their safety in school. Reactions of victims to peer bullying have been extreme, as in the cases of the rampage school shooters. Primarily, current research has not focused on the high school adolescent, although most school shooters arise from that age group. The overall purpose of this study was to examine the psychosocial responses by adolescent male victims to peer bullying. Research questions addressed the frequency and severity of peer-victimization, distress, anxiety, and their perception of …

Heavy Metal Adsorption On Iron Oxide And Iron Oxide-Coated Silica : Macroscopic, Spectroscopic, And Modeling Studies, Ying Xu

Dissertations

To accurately model metal mobility and bioavailability in soils and sediments, systematic sorption studies are needed using representative and well-characterized minerals. Two important surfaces are iron oxide and silica, which are ubiquitous and associated with one another in the environment playing important roles in metal distribution. The objectives of this research are to develop models for predicting speciation and mobility of toxic trace metal ions in groundwater, soils, and sediments when competing ions are present. A model system for soils and sediments, iron oxide-coated silica, was synthesized; the degree of coatings was highly sensitive to the particle size of silica …

Nursing Students' Knowledge And Attitudes Regarding Pain And Pain Management, Ruth L. Schaffler Phd

Dissertations

Pain is a universal human experience and is a primary reason people seek health care; however, undertreatment of pain has been reported in the literature as a significant clinical problem for more than three decades. Researchers have concluded that nurses have inadequate knowledge of pain assessment, are misinformed about opioids, and have inappropriate attitudes about pain and pain management that lead to the undertreatment of pain. One question is whether those misconceptions are acquired in nursing school or whether they are present when students enroll in nursing programs. The purpose of this quasi-experimental study was to examine the attitudes regarding …

Study Of Si/Sio2 Interface Passivation And Sio2 Reliability On Deuterium Implanted Silicon, Tias Kundu

Dissertations

One of the major defects that contribute to the interface states in the silicon band gap is the dangling bond, which degrades performance of MOS devices. Passivation of these bonds with hydrogen had been found to diminish their effect but the improvement degrades the operation due to hot electron effect. Passivation with deuterium annealing has proven to improve the lifetime of the metal oxide semiconductor devices but this technique is not very effective for a multi-level metal-dielectric structure. This work investigates and optimizes incorporation of deuterium by ion implantation into the silicon substrate before the growth of 6.5 nm thin …

Robust Techniques And Applications In Fuzzy Clustering, Amit Banerjee

Dissertations

This dissertation addresses issues central to frizzy classification. The issue of sensitivity to noise and outliers of least squares minimization based clustering techniques, such as Fuzzy c-Means (FCM) and its variants is addressed. In this work, two novel and robust clustering schemes are presented and analyzed in detail. They approach the problem of robustness from different perspectives. The first scheme scales down the FCM memberships of data points based on the distance of the points from the cluster centers. Scaling done on outliers reduces their membership in true clusters. This scheme, known as the Mega-clustering, defines a conceptual mega-cluster which …

Variable Permittivity Dielectric Material Loaded Stepped-Horn Antenna, Ozgur Ozdemir

Dissertations

Stepped-horn antenna loaded with dielectric material of variable permittivity is proposed to improve radiation characteristics and/or to increase the electrical dimensions of the radiating structure compared to unloaded empty one. A hybrid numerical technique is used to analyze such an antenna. The tapered section of the horn antenna is modeled by multi-stepped waveguide structures filled with variable dielectric constant material. Generalized scattering matrix representation of the tapered section of the horn antenna is obtained using mode matching technique. The radiating aperture problem is solved by the method of moments, under the assumption that the horn is terminated by an infinite …
