The semi-structured interviews asked mothers, and some fathers, to tell the story of their child's diagnosis process. The data revealed that the process is very individual for each family. The results are shared in the …

Education, Fascism, And The Catholic Church In Franco's Spain, Joan Domke

Dissertations

Societies in transition are vulnerable to strong forces for political change. When Franco's fascist government defeated the socialist party that had taken control from 1931 to 1936, it aligned itself with Spain's Catholic Church. For most of Spain's history, the established Church culture had been inseparable from Spanish identity and Catholicism was taught in all schools, private and public. Therefore, under the guise of religion, the government used the educational system as a means of socialization, connecting nationalism and religion to promote their fascist agenda. The purpose of this historiographic study is to examine the relationships among the school, government, …

This meta-analysis systematically synthesized results from 26 component studies, including dissertations and published articles, which reported at least one correlation between collective teacher efficacy and school achievement.

The research questions addressed the distribution of effect sizes for the relationship and the moderator variables that could explain any variance found among the studies. It was hypothesized that collective teacher efficacy would be strongly associated with subsequent student achievement, and that …

High School Teacher Attitudes Toward Implementing Positive Behavior Support Systems, Lauren Mcardle

Dissertations

Positive behavior support (PBS) is a systems change effort that entails explicitly teaching expected social behaviors and rewarding students for behaving appropriately. Additionally, PBS systems involve developing a hierarchy of consequences that are matched to the severity of behavioral infractions. While there is growing research support for the effectiveness of PBS systems in elementary and middle school settings, there is very limited research about positive behavior support implementation at the high school level. Preliminary studies suggest that teacher and staff buy-in and attitudes toward implementation practices are critical to implementation success at the high school level. Additionally, the some theoretical …

An Examination Of Internet Pornography Usage Among Male Students At Evangelical Christian Colleges, Paul Olaf Chelsen

Dissertations

Internet pornography access among male students at Evangelical Christian colleges presents two dilemmas. First, Internet pornography access is institutionally prohibited based on a Biblical view of sexuality. The second dilemma is that individual students who choose to follow the teaching of Jesus Christ in the context of Evangelical Christian faith tradition can experience internal distress in response to Internet pornography access. No empirical study to date has examined Internet pornography access only among male undergraduates only at Evangelical Christian colleges. The first guiding research question is, "To what extent do male undergraduates at select Evangelical Christian colleges in the Midwest …

“Voluntary Sector-Rich” And “Voluntary Sector-Poor”: What Difference Does The Distinction Really Make?, Lindsey M. Mcdougle Phd

Dissertations

Nonprofit organizations serve a distinctive role within American society. Collectively, nonprofits are viewed as major sources of social capital, contributors to the public good, and the value guardians within communities. Nonprofits also have a sizeable (and quite positive) impact on the nation's economy. Despite the social and economic significance of nonprofits, though, research has shown that nonprofit organizations and resources are not always distributed evenly across communities. Indeed, Wolch (1990) has observed that some communities are voluntary sector-rich, while others are voluntary sector-poor. Therefore, many of the benefits often associated with the presence of nonprofits may not be actualized, or …

Spermatogenesis: Laser Microdissection Optimization, Deborah Ann Hansen

Dissertations

Studies link paternal environmental exposures to pesticides, herbicides, and radiation to adverse reproductive outcomes such as developmental delays, malignancies, and structural birth defects. To date, 900 children of Vietnam veterans with presumed Agent Orange exposure receive VA presumptive service connected benefits because these children have Spina Bifida. To date, there are limited data to explain the underlying causal mechanisms whereby paternal environmental exposures result in adverse reproductive events. Laser microdissection (LMD) is the only technology that allows the isolation of cell subpopulations from complex tissues such as the testes without disturbing the cell’s bimolecular signature. LMD is essential in the …

Avian Developmental Endocrinology: The Effects And Role Of Yolk Hormones, Sibling Dynamics, And Life-History, Corinne Patricia Kozlowski

Dissertations

Inter-specific variation of the endocrine system is an underlying component for variation in avian life-history. Females deposit hormones into the yolks of their eggs, and embryonic exposure affects nestling phenotype. Hormones are also produced endogenously by developing nestlings, further influencing their behavior and physiology. This dissertation examines the role of the endocrine system in development by focusing on several different avian taxa. Yolk hormone concentrations often vary across the laying order and may mediate hatching asynchrony. These patterns were characterized in two species that lay asynchronously hatching clutches: Eastern screech owls (Megascops asio) and cockatiels (Nymphicus hollandicus). The patterns described …

Policy Determinants And Medicaid Managed Care, Diane Elizabeth Brandt

Dissertations

The U.S. Medicaid program is increasingly challenged by reductions in federal entitlement spending, a faltering private sector health insurance base, escalating health care expenditures and an aging and increasingly diverse population. Converging pressures on state Medicaid programs have challenged state policy makers to find new approaches to enhance program efficiency. One of these policy tools is the adoption of Medicaid managed care programs for individuals with chronic illness and disability, particularly important as these enrollees incur the highest health care costs. The increasing prevalence of chronic illness combined with the growth of households in poverty creates significant implications for Medicaid …

The Speaking Cognitions And Attention Scale: An Empirically-Derived Measure Of Public Speaking Anxiety, Robert Drew Beck

Dissertations

Although public speaking anxiety is one of the most commonly reported causes of both clinical and non-clinical anxiety, many of the currently used questionnaire measures of public speaking anxiety do not reflect the advances made in recent decades regarding empirical methods of test construction, including item generation and determination of subscale composition. The current study administered 35 empirically-generated cognitive self-statement items related to speaking anxiety to a sample of 367 undergraduate students along with measures of public speaking anxiety, fear of negative evaluation, generalized social anxiety behaviors, and self-consciousness tendencies. Using exploratory factor analysis and item-total correlations, participant responses to …

Toward Automated Detection And Diagnosis Of Mammographic Microcalcifications, Imad Mohammad Zyout

Dissertations

Mammographie diagnosis is the most effective technique to detect breast cancer in its infancy when it is most responsive to treatment. An early and a significant indicator of breast cancer is the presence of clustered microcalcifications (MCs). Mammographie MCs greatly vary in their appearance and shape, and become indistinguishable when surrounded by dense breast tissue. This makes radiologist's interpretation of mammograms a tedious and an error prone task.

Although computer aided diagnosis (CAD) methods are being developed to aid radiologist in detecting and analyzing the malignancy of MCs, existing systems have not achieved a satisfactory performance. The specificity of existing …

Examining The Effectiveness And Efficiency Of Two Delivery Models To Teach Children Abduction Prevention Skills, Kimberly E. Seckinger-Bancroft

Dissertations

Nearly all children receive abduction prevention training. Most traditional education programs increase the learner's knowledge, but often fail to produce concomitant behavior change. Behavioral Skills Training (BST) is a multicomponent, behavior-based training strategy with empirical support demonstrating its effectiveness in teaching children safety skills, behavioral generalization and maintenance over time. BST, however, is restricted by financial, human and time costs and limited resources to implement the training protocol. These factors likely limit widespread adoption of the training model. This study examined the use of computer-based instruction that emphasized active responding and mastery level performance requirements to teach school-aged children abduction …

Mainstreaming Evaluation: Four Case Studies Of Systematic Evaluation Integrated Into Organizational Culture And Practices, Amy M. Gullickson
