"Their Past In My Blood": Paule Marshall, Gayl Jones, And Octavia Butler's Response To The Black Aesthetic, Williamenia Miranda Walker Freeman

Dissertations

Paule Marshall’s The Chosen Place, The Timeless People (1969), Gayl Jones’ Corregidora (1975), and Octavia Butler’s Kindred (1979) enhance our conceptualization of black aestheticism and black nationalism as cultural and political movements. The writers use the novel as genre to question the ideological paradigm of a black nationalist aesthetic by providing alternative definitions of community, black women’s sexuality, and race relations. Because of the ways in which these writers respond to black aestheticism and black nationalism, they transform our understanding of movements often perceived as sexist, racist, homophobic, and anti-Semitic. An examination of their works reveals the need for additional …

Shock Rhetoric, David Robert Nelson

Dissertations

Social movements create a public perception of themselves through rhetorical messages and demonstrations. In order to gain the public's attention, some radical groups use any rhetorical means necessary, including offensive remarks and conduct. Groups, such as the Westboro Baptist Church and Bash Back!, rhetorically challenge the boundaries of prudence. The purpose of this study is to identify, depict, and provide insight regarding shock rhetoric. This study will compare protest methods, visual imagery, and language choices used by Bash Back! and the Westboro Baptist Church. This dissertation helps illuminate why and how groups or individuals use shock rhetoric.

Adaptation Of Balanced Scorecard And Multiple Criteria Decision-Making Methodologies To Measure Nation-State Power, Gregg Eric Lassen

Dissertations

The objective of this research was to develop a model for nation-state power. People interested in international relations, including scholars, diplomats, and analysts, need to understand relative power among nation-states, but the unit of comparison, power, remains an elusive concept. This research utilized a Balanced Scorecard approach from business and organizational behavior literature to develop a more comprehensive model of nation-state power based on international relations literature. The model was then further developed into a ranking tool which utilized multiple criteria decision-making theory. The combination of these approaches provided a tool that was used to measure nation-state power based on …

The Knowing-Doing Gap: The Influence Of Teacher Feedback In Changing Principal Behavior - A Mixed Methods Study, Kimberly St. Martin

Dissertations

This mixed methods study attempted to determine how a system of regular feedback from teachers on principal's work influenced the way in which two principals incorporated the 21 Leadership Responsibilities into their daily practice. Since Principals are the front line of school reform, even when a school commits to an improvement effort that is well grounded in research such as Response to Intervention (Rtl), the principal plays a key role in leading the change of adapting the school processes, culture, roles and responsibilities, norms, and systems to support implementation. To play this role effectively, the principal often finds it necessary …

Integrated Approach For The Assessment And Development Of Groundwater Resources In Arid Lands: Applications In The Quetta Valley, Pakistan, Zhanay Sagintayev

Dissertations

The lack of adequate field measurements (e.g., precipitation and stream flow) and difficulty in obtaining them often hampers the construction and calibration of rainfall-runoff models over many of the world's watersheds, leaving key· elements of the hydrologic cycle unconstrained. I adopted methodologies that rely heavily on readily available remote sensing datasets as viable alternatives and useful tools for assessing, managing, and modeling the water resources of such remote and inadequately gauged regions.

The Soil and Water Assessment Tool was selected for continuous (1998-2005) rainfall-runoff modeling of the northeast part of the Pishin Lora basin (NEPL), a politically unstable area that …

A Paradigm For Effective Pre-College Classical Guitar Methodology: A Case Study Of Two Models Of Effective Instruction, Renthungo Merry

Dissertations

Many classical guitar teachers of the past had stated that the field of classical guitar education in general was an area that was in need of re-evaluation in terms of proper teaching methodology, especially at the beginner level. However, the last twenty years have seen the steady growth and expansion of classical guitar education. Various factors have contributed to this, including new and innovative methods of teaching, the construction of better instruments, the proliferation of new music written specifically for the classical guitar, and the growth of guitar programs in elementary and secondary levels of instruction. The purpose of this …

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 …

From Reproduction To Consumption: The Economic Deterioration Of Families In The United States After World War Ii, Michael David Gillespie

Dissertations

The United State's “great recession,” beginning in December 2007, is the latest indicator of the economic decline of middle- and working-class families. This research questions why the economic condition of U.S. families deteriorated after World War II. To address this research question, social structure of accumulation theory is used to examine the changing role of the family as an institution in capitalist society.

First, a qualitative institutional analysis of federal welfare, labor, and financial regulatory policies from the New Deal to the present is conducted. This analysis shows that, initially, the family was vital to the capitalist economy as the …

Teaching, Learning, And Writing In The Third Space: A Study Of Language And Culture Intersecting With Instruction, Susan Toma-Berge Edd

Dissertations

The purpose of this dissertation was to compare the characteristics and attributes of an effective first grade teacher of writing to English learners through the lens of the "third space." The "third space" represents a place where sociocultural theory interacts with language and culture, and authentic, integrated literacy instruction. Because there is no empirical evidence to support the theory of the "third space" the observation and interview data were analyzed using literature that draws on three areas of study: English learners, first grade literacy, and urban schools. The key findings from this study produced three themes that came about by …

Using High-Powered, Frequency-Narrowed Lasers For Rb/129xe And Cs/129xe Spin-Exchange Optical Pumping To Achieve Improved Production Of Highly Spin-Polarized Xenon For Use In Magnetic Resonance Applications, Nicholas Whiting

Dissertations

Nuclear magnetic resonance (NMR) spectroscopy has been extensively used to investigate numerous systems of interest, ranging from collections of molecules to living organisms. However, NMR suffers from one key drawback: an inherent lack of detection sensitivity, as compared to other common forms of spectroscopy. This is due to the minute nuclear magnetic moments and low nuclear spin polarization levels at thermal equilibrium (~10-5 to 10-6), and thus necessitates the use of relatively large sample volumes. One way to overcome this low detection sensitivity is to introduce a species with highly non-equilibrium nuclear spin polarization, such as `hyperpolarized' xenon-129. Hyperpolarized xenon …

Biochemical Characterization Of Theromin, A Novel Leech Inhibitor, And The Interaction Between The Fourth Metalbinding Domain Of Wilson Disease Protein And Its Copper(I) Chaperone Hah1, Brian A. Zeider

Dissertations

Theromin, a novel thrombin inhibitor from the leech Theromyzon tessulatum, has been shown to be the strongest inhibitor to date. There has been a lot of attention on direct thrombin inhibitors as a much more efficient drug for anticoagulation therapy. One main reason for the need of strong direct thrombin inhibitors is that the current therapy, heparin, causes alternative clotting events in some patients where antibodies are made to the heparin/thrombin complex and causes clots to occur by different methods. Recently there has been a strong inhibitor from a leech used, hirudin, that can inhibit with a K_{i …}

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 …

Experimentally Reducing Preset And Hysteresis Effects In Creating A Non-Linear Model For Brake Hoses, Jai Thomas

Dissertations

This research investigates a brake hose simulation model that includes the effect of nonlinear torsional stiffness in addition to the usually considered bending stiffness on brake hose shape. A simulation model consisting of beams and torsion springs is presented in this research to predict brake hose shape when it is twisted through different angles. This knowledge can help reduce the possibility of a significant source of failure related to brake hose abrasion on nearby structures, thus eliminating the safety hazard of a premature failure of hoses. This would also eliminate the need for polymer bumpers at the rub points since …

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

Dissertations

Following a literature review, a researcher generated a descriptive theory of evaluation mainstreaming, the integration of systematic evaluation into the culture, systems, and job responsibilities of organizations. She then explored the validity and generalizability of the theory in the National Science Foundation’s grant-funded Advanced Technological Education Program using mixed methods research. Four centers were chosen based on quantitative survey responses which suggested that the organizations were likely to be mainstreaming evaluation. For each center, the researcher conducted a site visit, interviews, and document review to understand (i) the processes by and extent to which evaluation became part of everyday operations; …

The Interface Of Breastfeeding And Work: A Phenomenological Exploration Of The Experiences Of White Low-Income Women, Jessica A. Kerby

Dissertations

Vocational psychologists have been called to expand the traditional discourses related to work and career to address the actual work experiences of individuals, especially those of the working class. Breastfeeding rates are on the rise among employed women and mothers of low-income, but little is known about women of low income who seek to concurrently work and breastfeed. Work-family interface theories suggest employed mothers of low-income may experience conflict and/or enhancement through multiple roles. The purpose of this research was to answer the call to vocational psychologists, give voice to the narratives around breastfeeding and work among lowincome mothers, and …

The Allocation Of Time And Goods: Three Essays On American Household Shopping Behavior, Jing Cai

Dissertations

Consumers’ shopping behavior connects market goods expenditure with the out of- market time allocation in their daily time use. This study is composed of three essays. In the first essay, data are collected from the American Time Use Survey and it is found that an individual’s time devoted to shopping is positively determined by opportunity cost of time. Grocery shopping and other shopping, as two distinct types of shopping, react differently to a series of individual and household characteristics as well as by seasons. The corresponding marginal effects also differentiate between shopping time, leisure time, and home production time. In …

Counseling Professionals' Attitudes Toward Transgender People And Responses To Transgender Clients, Emily A. Nisley

Dissertations

The multicultural counseling movement emphasizes the critical nature of counselor attitudes in providing culturally competent service (e.g., Sue, 2001; Sue, Arredondo, & McDavis, 1992; Sue et al, 1982; Sue & Sue, 2003). Until recently, however, the counseling professions have paid little attention toward transgender people as a cultural minority group. The purpose of this study was to conduct the first assessment of counseling professionals' attitudes toward transgender people and to examine relationships between such attitudes and responses to a transgender client.

A national convenience sample of 138 master's and doctoral level counselors and counseling psychologists, recruited via electronic mailing lists, …

Confidence Intervals And Tests On The Difference Of Means Of Two Delta Distributions, Karen Grace Villarente Rosales

Dissertations

Various research fields produce data that are lognormally distributed and inflated with zero values. This type of data follows a delta distribution. In this study, we want to extensively investigate different interval and hypothesis testing methods for comparing the means of two delta populations to see which methods are optimal under different conditions of the populations.

For confidence intervals, existing MVUE methods are extended to two sample cases and compared to classical and two proposed robust methods. We investigated the performance of the classical Student's t, Welch t, and Wilcoxon-based interval to see if these methods really perform badly on …

Effects Of Yellow Rectangular Rapid-Flashing Beacons And Novel Lane Markings On Motorists’ Yielding, Speed, And Headway At Multilane Uncontrolled Crosswalks, Jimmy Wayne Shurbutt

Dissertations

Several methods have been examined to increase motorists’ yielding to pedestrians and the distance at which they yield on multilane crosswalks at uncontrolled locations with relatively high average daily traffic (ADT). A series of 5 experiments were conducted to evaluate the efficacy of rectangular rapid-flashing beacons (RRFBs) as effective pedestrian crossing aides. The first experiment found that the RRFBs produced a significant increase in yielding behavior at all 26 sites located in 3 cities in the United States. Data collected over a 2-year follow-up period at 22 of these sites plus 14-month follow-up at an additional 4 sites documented the …

Composing Ourselves: Utilizing Literacy Narratives To Promote Knowledge And Reflection In Preservice Secondary English Teachers, Cheryl Henderson Almeda

Dissertations

My research entails examining and interrogating the literacy narratives written by six preservice secondary English teachers before their first semester of teaching. After writing their literacy narratives, these teachers worked together in two focus groups to consider, celebrate, and interrogate their memories they recorded in their narratives. They shared conversations which focused on their reflections, their teaching strategies, and the ideas they embraced as newly forming teachers.

This study considers claims made by Dewey (1933), Lortie (1975), Schulman (1986), and others, who emphasize the importance of learning through observation and the intuitive nature of reflective learning and teaching. It emphasizes …
