Leadership Practices Of Science Department Chairs In Secondary Public Schools, Kathryn Marie Baal

Dissertations

This study was designed to explore the transformational leadership practices of science department chairs as perceived by both science department chairs and their principals as measured quantitatively by the third edition of the Leadership Practice Inventory (LPI) (Kouzes & Posner, 2007). In addition to transformational leadership, three other paradigms of leadership were essential to this study: transactional leadership, teacher leadership, and distributed leadership. Science department chairs are recognized as formal teacher leaders, primarily because their situational position makes them formal leaders; in addition science department chairs teach, to some degree, hence they are acknowledged as teacher leaders. The study further …

Meta-Analysis Of The Relationship Between Collective Teacher Efficacy And Student Achievement, Rachel Jean Eells

Dissertations

Collective teacher efficacy is an emergent school level variable reflecting a faculty's collective belief in its ability to positively affect students. It has been linked in the literature to school achievement. 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 …

Incompatible: The Construction Of The Homosexual Subject In American Mainline Protestantism, John Joseph Anderson

Dissertations

Many American mainline Protestant denominations discriminate against gays and lesbians or have discriminated against them in recent history by denying ordination to "self-avowed practicing homosexuals." This dissertation analyzes such ordination policies and their enforcement in ecclesial courts in three denominations, the United Methodist Church, the Presbyterian Church (USA), and the Evangelical Lutheran Church in America. Moving from a theoretical framework that integrates Michel Foucault's theories of discourse and subjectivity with Christian body theology, this dissertation argues that the language of the "self-avowed practicing homosexual" discursively produces a homosexual subject that does violence to gays and lesbians in these churches.

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 …

Exploring Diverse Blended Families: Using Critical Discourse Analysis To Hear Their Voices, Robin Moore-Chambers

Dissertations

It has been predicted that if you were born in the 1980s and 1990s, there was a one in two chanceof either living in a blended family as a child or as an adult (Coleman, Ganong, & Fine, 2000).In 1989, Glick predicted that in the 21st century, blended families would be the leading family form. Today in 2010, they are far from being a new phenomenon (Stewart, 2008). They are a rapidly growing part of the American population according to Census data and over half of American families may be blended, i.e., formed by (married or non-married) partners with children. …

Role Of Amyloid Beta Assembly State In The Human Immune Response, Deepa Viswanathan

Dissertations

Alzheimer’s disease (AD) is a slowly progressing neurodegenerative disease that leads to dementia. Histopathological hallmarks that characterize AD are senile plaques formed by extracellular deposition of Amyloid beta (Aβ) peptide and intracellular aggregates of hyperphosphorylated tau protein. The plaques, which are found in the brain parenchyma, comprise both 40 and 42 residue Aβ. Aggregation of Aβ is an established pathogenic mechanism in AD, but little is known about the initiation of this process in vivo. Several studies have revealed significant inflammatory markers such as activated microglia and cytokines surrounding the plaques. Plaques are a hallmark of AD, but they are …

Activation Of Propargylic Alcohols By Piano-Stool Ruthenium Complexes Bearing Phosphoramidite Ligands, Stephen Andrew Costin

Dissertations

Various piano-stool ruthenium complexes bearing phosphoramidite ligands have been synthesized and characterized spectroscopically and in some cases structurally. Reaction of phosphoramidite ligands with an appropriate metal precursor gives new piano-stool ruthenium complexes [RuCl(L)(arene)(phosphoramidite)], where L = Cl, PPh3, or others. The novel complexes are tested for their ability to activate propargylic alcohols catalytically as well as stoichiometrically. Specifically, catalytic substitution of propargylic alcohols via allenylidene intermediates is envisioned. Stoichiometric reactions designed to form stable, isolable allenylidenes are sought as well. h6-p-cymene complexes of the type [RuCl2(h6-p-cymene)(phosphoramidite)] activate propargylic alcohols in the reaction with carboxylic acids to form b-oxo esters. The …

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 …

Outsourcing The American Dream: An Analysis Of The Re-Employment Potential Of U.S.-Based Call Center Workers Within The Context Of Globalization, Wendell Allen Robbins Iii

Dissertations

This study examines call center workers in order to determine the effects of globalization on this class of service sector workers and to determine their reemployment potential. A major component of globalization is free trade, which enables offshore outsourcing (offshoring). Outsourcing often has the “Robin Hood” effect of taking jobs from rich countries and sending them abroad in a cost-saving effort, further, the competition of the global market has the capability of upsetting the current social and economic stability and prosperity. While this improves the quality of life for those in the poor country whose economy has developed as a …
