Four research questions guided this study: 1) How do individuals with autism and the people who support them describe their relationship? Specifically, how was the relationship established, how has it changed, what are the benefits and challenges, what works and what does not, and how is the relationship maintained? 2) From the perspective of both the individuals with autism and the supporting individuals, how do their relationships provide support for the individual with autism? 3) How does the mode of communication influence …

Reconsidering Academic Dishonesty: A Critical Examination Of A Complex Organizational Problem, Tricia Bertram Gallant Phd

Dissertations

Academic dishonesty, traditionally framed as a problem of student agency, plagues higher education institutions. In order to facilitate leadership toward the resolution of the problem, this study reconsiders academic dishonesty as a symptom of the complex interplay among agency, structure, and culture. The theoretical framework utilized, which I call Systemic Interactionism, builds on existing sociological, leadership, and organizational theories to provide a more robust explanation of academic dishonesty and other complex organizational problems. This reconsideration of academic dishonesty occurs in the context of three American higher education institutions. I employed a variety of field methods (interviews, observations, and document analysis) …

This small urban district has focused its resources on the re-design of its K-8 classrooms and curriculum to support educational reform through the use of technology, including hardware, software, and teacher professional development. Current best practices suggest that while staff development may begin with conventional in-service training, it should move quickly beyond to efforts that support teachers’ development as professionals involved in decision-making, inquiry, and leadership in their classroom teaching. In order to develop as professionals, teachers specifically need help and support in integrating new knowledge and …

An Overview Of Gerald R. Prescott’S 1935 “The Prescott Technic System” With Recommendations For A Contemporary Edition, Carson Lee Vermillion

Dissertations

Gerald R. Prescott (1902-2005) served as the Director of Bands at Mason City (Iowa) High School from 1927-31. During his tenure, Prescott established himself as an outstanding band director and music educator. While serving as the Director of Bands at the University of Minnesota, Prescott published The Prescott Technic System; a band curriculum employing excerpts from conservatory methods to develop individual technique. The system encompassed fourteen years of study, from beginning band through graduate school.

Due to the performance expectations placed on today’s instrumental music programs, little time remains for a sequenced individual course of study that adequately develops a …

Markov Chain Monte Carlo Methods For Regression Splines With A Penalized Acceptance Ratio, David Keith Stamps

Dissertations

An increasingly popular method for fitting complex models, particularly with a hierchical structure involvese the use of Markov Chain Monte Carlo simulation. Within a Bayesian framework, two major strategies are Gibbs sampling and Metropolis-Hastings methods. Recent research in the area of MCMC methods has witnessed the emergence of modeling efforts which permit the movement of the chain across models of varying dimensions. When properly constructed, such Markov chains converge to the joint posterior distribution of the parameters to be estimated, making Bayesian averaging an attractive option after convergence has occurred. With this transdimensional methodology, the Bayesian averaging process takes place …

The Effects Of Rumination On Problem-Solving Self-Efficacy And Self-Efficacy For Controlling Upsetting Thoughts In The Context Of Depressive Symptoms, Christina Marcia Gilliam

Dissertations

Two cognitive variables that are of interest in their role in depression are self-efficacy and rumination. Self-efficacy refers to individuals¿ own appraisal of their ability to successfully accomplish a domain of tasks (Bandura, 1977). Rumination, as defined by Response Styles Theory (Nolen-Hoeksema, 1991), refers to the process of repetitively and passively thinking about negative emotions, consequences, and symptoms of distress. Although the relationship between these two constructs and depression has been examined in both experimental and correlational studies, there has been minimal research on the relationship between self-efficacy and rumination among depressed individuals. The present study was intended to replicate …

Constructing Meaning Through Religious Coping: Rebuilding The Shattered Assumptive World Of Mothers Bereaved By Homicide, Accident, And Illness, Laura Thea Matthews

Dissertations

Researchers have begun to examine the theory that religion may help bereaved individuals to provide meaning to an otherwise inconceivable event. In addition, work by Janoff-Bulman (1989; 1992) and others (see Kauffman, 2002) has spawned a growing understanding that bereavement forces individuals to restructure and rebuild previously held assumptions about the self and the world. This study examined mediator-moderator effects of positive and negative religious coping on relationships between grief intensity and world assumptions in 117 mothers bereaved by the death of a child (homicide, illness, or accident). Mothers with higher grief intensity rated the world as less meaningful and …

The Power Of "Estudentprotest:" A Study Of Electronically-Enhanced Student Activism, James Patrick Biddix

Dissertations

Both student activism and Internet use by students are among the fastest growing variables in national reports of student engagement (Astin, 2004; Levine & Cureton, 1998b). This study introduces the term estudentprotest to describe how contemporary student activists use information and communication technologies (ICTs) for protest. A sequential mixed methods design (Creswell, 2003) was utilized. This approach involved obtaining statistical information from a sample for descriptive and outcome analyses, using the results to suggest nodes for an investigation of social networks, and finally interviewing individuals to explore those results in more depth. This study found that today¿s student protests begin …

Biogeography Of Buarremon Brush-Finches (Aves, Emberizinae): Integrating Ecology, Evolution, And Systematics, Carlos Daniel Cadena

Dissertations

Ecological and historical approaches to studying species¿ geographic ranges have yet to be unified. Ideal scenarios for integrating ecology with evolutionary biology in biogeography are those where contemporary ecological interactions may have influenced species¿ distributions historically, driving the evolution of ecological niches. I focused on understanding the origin of elevational distributions of species, and specifically on the role of interspecific competition in the origin of complementary elevational ranges. To test hypotheses about the origin of elevational distributions, I followed a combined approach involving molecular phylogenetics, phylogeography, population genetics, and ecological niche modeling. I focused on Buarremon torquatus and B. brunneinucha …

Image Segmentation By Energy And Related Functional Minimization Methods, Eric Hudson Mason

Dissertations

Effective and efficient methods for partitioning a digital image into image segments, called ¿image segmentation,¿ have a wide range of applications that include pattern recognition, classification, editing, rendering, and compressed data for image search. In general, image segments are described by their geometry and similarity measures that identify them. For example, the well-known optimization model proposed and studied in depth by David Mumford and Jayant Shah is based on an L₂ total energy functional that consists of three terms that govern the geometry of the image segments, the image fidelity (or closeness to the observed image), and the prior …

The Impact Of Sexual Abuse And How Children Cope: Different Perspectives From Caretakers And Children, Megan M. Schacht

Dissertations

Child sexual abuse is a complicated stressor with a broad range of associated symptoms. It has been suggested that the coping techniques children utilize may act as a mediating variable in the relationship between child sexual abuse and subsequent difficulties. Until recently, child sexual abuse sequelae were assessed in a piecemeal fashion, with individual tests for each symptom domain and reporter. However, recent developments in the area of trauma assessment have provided researchers with complementary caretaker- and self-report measures to assess a broad range of trauma-related symptoms (i.e., the Trauma Symptom Checklist for Young Children [TSCYC] and the Trauma Symptom …

Is Rumination General Or Specific To Negative Mood States? The Relationship Between Rumination And Distraction And Depressed, Anxious, And Angry Moods In Women, Jessica Lauren

Dissertations

Rumination has been found to play a role in negative affect by either maintaining or increasing depressive, anxious, and angry moods, whereas distraction has been found to decrease these negative moods. This experiment tested the hypothesis that the effect of rumination occurs across mood states and is not specific to one type of negative mood, using both Nolen-Hoeksema¿s Response Styles Theory (RST; 1991), and Bower¿s Associative Network Theory (1981; ANT). The impact of rumination and distraction on depressed, anxious, and angry mood states were examined in 90 women at the University of Missouri ¿ St. Louis. Participants were randomly placed …

Faculty Development In The University Setting: Perspectives And Practices, Verna Josephine Dickson

“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 …

Audio Narration And Reading Ability In Programmed Instruction, Wendy Jaehnig

Dissertations

This study compared the effects of audio, textual, and audio-textual narration in a programmed instructional module on the performance of individuals with different reading abilities. One hundred eighty-four college students were randomly assigned to audio, textual, or audio-narration. Dependent variables were posttest score and instruction completion time. An ANCOVA was used to analyze the results, with ACT reading test scores as the covariate. No differences were found between the groups on posttest scores (p = .56) or completion time (p = .90), and there was no interaction between narration type and reading score for either dependent variable. Audio …

Exposure Of Nervous System Cells To Polychlorinated Biphenyls (Pcbs), Results In Alterations Of Neurotrophic Factor Expression, Gordon H. Gurley

Dissertations

Toxic insult by PCBs results in learning and memory deficits in humans. Alterations in expression of neurotrophic factors (NF) and/or their receptors have been linked to changes in learning and memory. How PCBs affect cognition is not known. We suggest that PCBs affect cognition by altering NF expression.

We exposed cultured C6 rat glioblastoma cells (an astrocyte cell-line) to medium containing PCB (Aroclor 1254 (10ppm)). Control cells were treated with dimethyl sulfoxide (DMSO) or regular medium. Enzyme-linked immunosorbent assays (ELISA) were used to determine glial cell-line derived neurotrophic factor(GDNF) and nerve growth factor (NGF) concentrations in all samples. We also …

On April 28, 2004, pictures of abuse and torture of Iraqi detainees at Abu Ghraib prison by U.S. military personnel shocked many Americans. In the wake of the images, it became clear that several military personnel were involved in the acts of torture and abuse. This dissertation explores the interconnections of larger structural factors, state policies, and individual actors in an attempt to understand how and why torture and abuse occurred at Abu Ghraib. It builds upon an integrated theoretical model of state and corporate crime. The dissertation revises this model so that it can better address the complexities o …

Electronic Government Accessibility For People With Blindness Or Low Vision Who Utilize Assistive Computer Technology, Robert J. Sobie

Dissertations

Citizen access to electronic government information and services continues to enjoy an expansionary phase in local government. This expansionary phase holds a prominent place in service delivery strategic planning as governments address on-going operational challenges caused by increased fiscal pressures and greater accountability to the citizenry for their actions. Since the advent of the World Wide Web, in the mid 1990s, static information and interactive applications are available on government websites to facilitate information dissemination and citizen interaction.

Robust Kanban Design For A Lean Supply Chain, Hardik Shah

Dissertations

This research concentrates on the inventory management decisions within an assembly-type supply chain. The need for this type of investigation is warranted by the fact that intense competition and heightening demand from customers have forced businesses to focus their attention on strengthening their supply chains. The problem is that in any supply chain, there are many factors involved that cause variations and instability within the system. Previous literature indicates that the manipulation of a Kanban system in today's uncertain environment generates unfavorable results. Consequently, the goal is to find a Kanbanmethodology that would produce robust and consistent results even when …

Providing Uninsured Adults With Free Or Low-Cost Primary Care: Does It Influence Their Use Of Hospital Emergency Departments?, Anne G. Zahradnik

Dissertations

This study analyzes one component of the health care safety net to determine whether or not being enrolled in a free or low-cost primary care physician access program subsequently affects emergency room utilization by uninsured adults ages 18 through 64. Those individual decisions are analyzed from both public goods and rational choice schemas. Additionally, physician access programs of different formats (a low-cost physician referral program and a freewalk-in clinic) are analyzed and compared for relative effectiveness. The study is a quantitative analysis of more than 40,000 individual patient records rather than relying on qualitative patient recall or on analyzing broad …

The Representation Of Race And Ethnic Relations In Japanese Junior High School English Language Textbooks From 1987 To 2002, Mieko Yamada

Dissertations

This dissertation explores how cultural attitudes about race/ethnicity are taught and how international power relations are expressed in Japanese junior high school textbooks. In a content analysis of Japanese junior high school textbooks in English as a foreign language, I examine how race and ethnic relationswere expressed and what types of interracial communication took place in the textbooks. Applying the racial formation theory developed by Omi and Winant (1994) and the concept of color-blind racism by Bonilla-Silva (2001, 2003), I explain how cultural ideology towards racial and ethnic relations were guided in the Japanese English language textbooks.

Fifteen English language …

Non-Traditional Paths To Presidencies Of Higher Education Institutions In Michigan, Daryl Joseph Delabbio

The number of college and university presidents coming from a career path outside of higher education has seen a steady increase, from just under 10% in1986, to over 15% in 2001 (Corrigan, 2002), yet little is still known about this growing population. This qualitative study examined four current or former presidents of institutions of higher learning in Michigan who were elected to their positions without having experienced the traditional academic career pathcommonly associated with college and university leaders. Four presidents, along with their current or former chief academic officers and two current or former members of the governing boards that …

The Persistence Of At Risk College Students Into Their 8Th Semester At A Private Christian College, Rick Zomer

Dissertations

It is estimated that the number of students who will begin a course of study but fail to complete a post secondary degree is between 28.5% (Tinto, 1993) and 50% (Brawer, 1990). This qualitative study reviewed sixteen students enrolled at a private Christian college who were deemed to be at risk based on specific pre-enrollment data but had successfully persisted into their senior year of college. Tinto's Theory of Departure and the role of mentoring were used as lenses to determine: (1) the role of individual intentions and commitments in their persistence; (2) the impact of social and educational congruence …

Nurse Practitioner Adoption Of Clinical Innovations, Rhoberta Jones Haley Phd

Dissertations

Adoption of clinical innovations by Nurse Practitioners (NP) is a complex phenomenon, rooted in personal values and influenced by challenges within health care environments. When clinical innovations are adopted or rejected by NPs, this decision has meaning for patients, NPs, health care agencies, and society. The decision controls the opportunity for patients to access a clinical innovation that could reduce morbidity and mortality, save money, and provide satisfaction related to the health care encounter. The purpose of the study was to increase knowledge about NP adoption of clinical innovations, particularly emotionally-laden clinical innovations. The lines of inquiry focused on what …
