“A Highly Ambiguous Condition”: The Transgender Subject, Experimental Narrative And Trans-Reading Identity In The Fiction Of Virginia Woolf, Angela Carter, And Jeanette Winterson, Jennifer A. Smith

Dissertations

This dissertation examines how the constantly evolving gender identity o f a text’s transgender subject relates to the text’s narrative structure and shapes the orientation o f the reader to the text. Accordingly, this project examines how these transgender narratives deploy experimental stylistic techniques that enhance the reader’s experience of ceaseless transitioning by revealing gender as a constant process that never solidifies onto a body and by highlighting the text’s own status as process rather than finalized product. Further, this project examines how a transgender subject and his/her relationship to the body, culture, and narrative is involved in the re-vision …

Advanced Methods In Automatic Modulation Classification For Emerging Technologies, Hong Li

Dissertations

Modulation classification (MC) is of large importance in both military and commercial communication applications. It is a challenging problem, especially in non-cooperative wireless environments, where channel fading and no prior knowledge on the incoming signal are major factors that deteriorate the reception performance. Although the average likelihood ratio test method can provide an optimal solution to the MC problem with unknown parameters, it suffers from high computational complexity and in some cases mathematical intractability. Instead, in this research, an array-based quasi-hybrid likelihood ratio test (qHLRT) algorithm is proposed, which depicts two major advantages. First, it is simple yet accurate enough …

Development Decision-Making In St. Louis: Institutions, Incentives And Urban Development, William Ernst Winter

Dissertations

This study uses the example of St. Louis to identify how local leaders make decisions about development and what factors influence the type of projects chosen. Through an analysis of projects conducted in the downtown and two distressed neighborhoods, the study concludes that St. Louis has a system of development decision-making that is substantially privatized and decentralized. At the center of development activity are place-based entrepreneurs who understand the local market and work to change the incentive structure for reinvestment. The leadership of the private sector in planning and implementing development policy is the flipside of local institutions that are …

Evolutionary Epidemiology Of Endemic Gal¿Pagos Birds And Their Parasites, Noah Kerness Whiteman

Dissertations

In order to better understand parasite diversification, I went to the Gal¿pagos Islands to study the ecology and evolution of a model bird-parasite system, which included four phylogenetically independent ectoparasite lineages infecting the Gal¿pagos Hawk (Aves: Buteo galapagoensis). The parasites comprised two lice (Insecta: Phthiraptera: Amblycera, Ischnocera), a lousefly (Diptera: Hippoboscidae) and an avian skin mite (Acari: Epidermoptidae). Ultimately, my goal was to examine ectoparasite evolutionary epidemiology and disease susceptibility in relation to the host¿s ecological and colonization history. At the outset, I hypothesized that parasite natural history was key in influencing the coalescent process. Accordingly, I found differences …

Superintendents ’ Perceptions Of Clinical Supervision Practices In A District-Wide Implementation Program, Myrna Rae Ladner Bourgeois

Dissertations

In 1990 a new idea swept through the educational industry. Forty-nine school districts in Pennsylvania instituted a new form of organizational management called clinical supervision. In effect, this was a change in the relationship between administration and teachers concerning instructional behaviors. Formerly, when teachers were supervised and evaluated by administrators, they felt intimidated. They also felt their privacy was being invaded. Clinical supervision is an attempt to organize the methodology of teacher supervision while improving instruction. The purpose of this study was to provide data to the participating school districts for use in developing supervision, evaluation, and involvement training modification …

School Web Sites And Teacher Employment Interest, David Theodore Freeman

Dissertations

The Internet has changed the way many organizations, including public and private schools, recruit and select employees. It has also changed the way many people research and pursue employment opportunities, including those seeking positions in education. The school Web site is often the medium of first contact between a school or school district and a potential employee. That first contact can influence the potential employee’s decision to actively pursue employment with a school or a school district.

This research measured the reactions o f preservice teachers who visited three grade-level appropriate school Web sites of “poor,” “average,” and “best” distinction. …

Acts 2:42 In 2006: Examining Small Group Discussion In An American Mega-Church, Sheri Guseman Edd

Dissertations

During the last century, Americans have become increasingly isolated from one another, resulting in feelings of loneliness and creating a void of community (Frazee, 2001). However, as attendance at mainline churches continues to decline (Stafford, 1998), attendance and participation in mega-churches, defined as those serving more than 2,500 individuals and offering a multiplicity of services, continues to increase (http://www.hirr.hartsem.edu/org ). One popular explanation for this phenomenon is that mega-churches are often characterized by an organized small group ministry---something absent in more traditional churches. Although this trend has clearly swept the nation (Gladwell, 2005), related research on the efficacy of the …

Dissertations

All Naval enlisted personnel and officers are required to attend Leadership Continuum courses at designated career intervals. One of the required courses for officers is the Intermediate Officer Leadership Training Course (IOLTC). This study replicated William F. Conroy III's 2001 dissertation study of graduates of the IOLTC offered in San Diego with graduates of a similar course offered by the Center for Naval Leadership (CNL) at Naval Amphibious Base (NAB), Little Creek, VA. Like the Conroy study, this study attempted to identify barriers and incentives that IOLTC graduates encounter on-the-job that either encourage or discourage their use of leadership skills …

Gender Influences In The Graduate Classroom: An Investigation Of Female And Male Student Perceptions, Gerald B. Blanton Edd

Dissertations

Defined by Mary Rowe (1977) as micro inequities, seemingly insignificant gender bias behaviors create an inequitable academic environment and marginalize groups and individuals in the American classroom. Popularized by Hall and Sandler's 1982 report on the "chilly" classroom, gender bias is subtle and differs from the more obvious behaviors associated with sexual harassment. However, gender bias research appears incomplete. Study findings contradict each other, few studies explore gender bias in the graduate classroom, and fewer yet compare the perceptions of women and men concerning gender influences in the graduate classroom. This dissertation investigates perceptions of the influence of gender in …

The Dilemma Of Disclosure For College Students With Attention Deficit Disorder, Teresa L. Spoulos Edd

Dissertations

Many college campuses are striving to recruit and retain a diverse student population, and one population making its presence known are students with disabilities. As a result of the Rehabilitation Act of 1973 and the Americans with Disabilities Act of 1990, students with disabilities are ensured equal access to education through the removal of architectural barriers and the provision of reasonable accommodations. Despite the existence of these laws, however, many students with attention deficit disorder (ADD) choose not to request classroom accommodations from professors. Students choose not to disclose out of fear of having inaccurate labels placed on them, being …
