Psychotherapist Understanding Of Genital Self-Mutilation Amongst Male To Female Transsexuals, Michael Robert Kenney

Dissertations

Self-mutilation of the genitals is a complex phenomenon that can provoke strong countertransference reactions amongst mental health clinician. Transsexuals who engage in self-inflicted mutilation of the genitals face a potentially increased risk of alienation from healthcare providers due to marginalization and lack of understanding by treating clinicians. Frequently, assumptions are made regarding the motivation for the behavior that fails to take into account the complex interplay between contributing psychological, social, and environmental forces.

This qualitative study explored the experience of four psychotherapists who had encountered the behavior in their work with transsexual clients in order to gain a more accurate …

High School Curriculum Tracks As Determinants Of Post-Secondary Outcomes: A Study Of Track Mobility And Its Effects, William Morrison

Dissertations

Despite scores of studies that have shown that tracking and ability grouping perpetuate the academic achievement gap that exists in the United States, the practice continues. The reason for this persistence is a confluence of educational, social, and political factors. As tracking will continue as practice for the foreseeable future, research must help to identify the best and worst of tracking practices so that its negative effects are minimized and positive effects maximized. Oakes (2005) has identified five common elements of tracking policies and practices: extent, pervasiveness, flexibility, mobility, and locus of control. Of these elements, it is my contention …

The Role Of Linker 2 (L2) Region In Rhtrim5Α Assembly And Hiv-1 Restriction, Jayalaxmi Sastri

Dissertations

The cellular restriction factor TRIM5alpha inhibits infection by numerous retroviruses in a species specific manner. TRIM5alpha protein from rhesus macaques (rhTRIM5alpha) and a related protein TRIM-Cyp from Owl monkeys restrict infection by HIV-1 while human TRIM5α (huTRIM5alpha) restricts infection by N-tropic murine leukemia virus (N-MLV) but not HIV-1. Several models have been proposed for retroviral restriction by TRIM5 proteins (TRIM5alpha and TRIMCyp). These models collectively suggest that TRIM5 proteins mediate restriction by recognizing specific determinants in the viral capsid and directly binding the capsid. Following binding, the TRIM5 proteins self-associate into large assemblies around the viral capsid, which leads to …

Relations Among Endogenous Attention, Executive Functioning, And Global Assessment Measures In Toddlers And Preschoolers Born Full-Term And Preterm, Nancy Wyss

Dissertations

Infants born prematurely now represent about 12% of all live births in the United States and are at risk for numerous developmental issues. For example, children born preterm are at an increased risk (2-3 times greater) for later attentional problems. With the high rate of attentional issues in later childhood, it is crucial to assess young children born preterm with a valid measure. Currently, global assessments are commonly utilized in neonatal follow-up programs as a broad-based assessment of children born preterm. However, they are often poor predictors of later functioning. There are many different components of attention, and experimental tasks …

International Education Exposure In Secondary Schooling: Impacting Academic Outcomes Among Urban Girls Of Color, Tiffini L. Andorful

Dissertations

Existing literature reveals a gap in research on high school students of color studying abroad. Therefore, this study seeks to provide an understanding and explanation of how international educational travel experiences and global education impact the educational outlook of urban high school girls of color. This study proposes that a positive educational outlook including a student's academic engagement, educational aspirations, motivation, perception of the world, and self-efficacy can later generate school persistence and predict high school completion despite the increasing rates of minority female dropouts and the potential effects of race, class, and gender.

Through a qualitative case study and …

Social And Emotional Learning: An Argument For Religious Pluralism, Debra Mayconich Baron

Dissertations

The purpose of this project is to argue that in order for social and emotional learning (SEL) goals to achieve their intended outcomes for students and society, religious pluralism must be reflected in student instruction. SEL involves the use of evidence-based practices to provide opportunities to develop competencies related to self-awareness, self-management, social awareness, relationship skills, and responsible decision making which are intended to enable students to demonstrate morally appropriate actions and ethical decisions, which I am calling "right behavior."

It is my argument that one's understanding of right behavior embodies both implicit and explicit moral beliefs based on one's …

Effect Of Advanced Age On The Innate Immune Response To Cutaneous Wound Infection, Aleah Lin Brubaker

Dissertations

An estimated 25 billion in US health care expenditure is spent on care of chronic, non-healing wounds. The failure to effectively heal wounds is often compounded by co-morbidities, such as diabetes or obesity. Another major patient population afflicted with chronic wounds are the elderly. Advanced age is associated with a decline in immunologic function that contributes to a poor response to vaccination, infection and tissue injury resulting in prolonged hospital stays and age-related morbidity and mortality. Specifically, clinical observations and laboratory studies have suggested an age-related decline in cutaneous wound healing, marked by protracted wound closure, wound dehiscence and chronic …

Fideism, Evidentialism, And The Epistemology Of Religious Belief, Matthew P. Butcher

Dissertations

Fideism is the theory that certain propositions can be held by faith without regard to evidence. Its epistemological underpinnings are often contrasted with evidentialism - the view that one is justified in holding a belief if and only if that belief is based on sufficient undefeated evidence. Recently, John Bishop and C. Stephen Evans have each forwarded new theories of fideism that oppose evidentialism. This dissertation examines these two theories, raising problems that threaten to undermine the epistemological claims of the fideist. A version of evidentialism is then advanced that addresses the problems identified by Evans and Bishop. Particularly important …

First Ladies Of The United States-Advocates For Children, Women Leadership And Social Causes: A Historical Examination Of Nancy Reagan And Hillary Rodham Clinton, Nimsiha Bhatt Kumar

Dissertations

In the twentieth and twenty-first centuries, First Ladies' greater involvement in presidential administration initiatives has allowed the role to evolve to be more influential in making social change in our country. Their desire to choose a cause to advocate during their time in the White House is due in large part to either personal connections or leadership goals that are assumed with a specific social or political cause.

The purpose of this study was to examined how two First Ladies, Nancy Reagan and Hillary Rodham Clinton, have developed, promoted and advanced social change for our nation's children and families to …

Addressing The Issue Of Meta-Analysis Multiplicity In Education And Psychology, Joshua R. Polanin

Dissertations

The concept of multiplicity, conducting multiple statistical significance tests in one study, has pervaded primary research over the last 7 decades (Hochberg & Tamhane, 1987). This continued discussion was due to the fact that multiplicity increases the probability of committing a Type 1 error (i.e., deriving a false conclusion). Little attention has been paid, unfortunately, to multiplicity in meta-analysis (Tendal, Nuesch, Higgins, Juni, & Gotzsche, 2011) and calls have been made for meta-analysis methodologists to address this critical issue (Bender et al., 2008). As such, the purpose and significance of this project was to answer these calls by formally quantifying …

Processes Underlying Syntactic Control: Evaluating Linguistically Diverse Children, Vanessa R. Raschke

Dissertations

The current study focused on the mechanisms involved in syntactic awareness development in monolingual and bilingual (English/Spanish-speaking) nine-year-olds. Inclusion of child language brokers (those who translate and interpret for non-English speaking family members) diversified the definition of "bilingual." Previous research has shown bilingual advantages in areas of metalinguistic awareness and executive function (e.g., Bialystok, 2010; Davidson, Raschke, & Pervez, 2010), however, child language brokers have not been distinguished in these studies. These children, due to early language-switching and translation duties, may have differential development of areas of inhibition, cognitive flexibility, and working memory, areas suspected to aid in metalinguistic awareness …

Reaping The "Colored Harvest": The Catholic Mission In The American South, Megan Stout Sibbel

Dissertations

A central paradox marks the story of the Roman Catholic mission in the American South. On one hand, the Church committed itself to providing access to quality education in underserved southern black communities. The establishment of southern Catholic schools for African American children supported the nation's traditional emphasis on education as a prerequisite for economic, social, and political advancement. Insofar as Catholic schools and sisters in the Jim Crow South offered opportunity in communities that otherwise lacked access to education, they demonstrated some of the best qualities traditionally associated with the United States of America.

On the other hand, Catholic …

Value-Centric Methodology For Requirement Verification Under Uncertainty, José F. Martin

Dissertations

The development of a Department of Defense (DoD) Product, no matter how simple or complex, will ultimately undergo the execution of a requirement verification plan to make sure that the product being developed meets the requirements that it was designed to meet. In DoD organizations, these plans are usually developed and executed with cost and schedule as two significant variables. Technical risk is also addressed but from the context of acknowledging that certain attributes have the potential to impact cost, schedule, or mission. While other influential pressure points are also critical (e.g., expected results, benefits, and uncertainty) these do not …

Comparing The Effectiveness Of Two Models Of College Summit Programs In An Urban School Setting, Wanda Davis

Dissertations

The inclusion of college preparation programs promote and forecast academic success in postsecondary studies among individual at-risk, African American urban high school students. Past research has shown ongoing, college acceptance, performance, and graduation gaps between at-risk, African American urban high school students when compared to affluent, Caucasian suburban high school students. The College Summit program is designed to help close this gap. The study compared two models of the College Summit Program in one urban school setting. The study evaluated the effect that pre-college preparation activities had on these dependent variables: completion of postsecondary planning activities, end-of-year GPA, awards of …

Environmental Factors Influencing Oxidative Stress In Respiratory Cells, Carresse L. Gerald

Dissertations

Agriculture workers inhale a variety of dusts, gases, microbes and compounds on a daily basis. Several respiratory diseases display inflammation and oxidative stress as key factors of pathogenesis. To better understand the effects of agricultural dusts on the airway there first needs to be characterization of dust components. Thus, we hypothesized that confinement facilities contain high levels of respirable particles, bacteria, and elements of respiratory importance. We further hypothesized that SCF dust alone or in combination with diepoxybutane (DEB) will result in oxidative stress and phytonutrients from the sorrel plant will reduce these effects. Several bacterial species were identified via …

A Descriptive Study Of The Leadership Role Of Community Health Ambassadors On Diabetes-Related Health Behaviors, Barbara Pullen-Smith

Dissertations

Diabetes is a chronic disease that bears a disproportionate burden among African American populations. The lack of access to affordable, culturally appropriate health care is a key barrier to effective diabetes prevention or disease management for racial/ethnic minority populations. Living in public housing communities, with concentrated poverty, exacerbates the burden of diabetes and reduces access to screening and early detection services to prevent the onset of diabetes. The purpose of the study was to describe the leadership role of lay health advisors, known as Community Health Ambassadors (CHAs), on diabetes-related health behaviors of African Americans living in a public housing …

Monitoring Damage Initiation And Growth In Composite Structures By Acoustic Emission Method, Kassahun Mekonnen Asamene

Dissertations

In this dissertation, acoustic emission technique is examined as candidate for monitoring the integrity of polymer matrix structural members. Acoustic emission technique has so far been largely limited to laboratory tests and field applications have been mostly limited to qualification tests of aerospace structures. The lack of quantitative indications of damage in composite structural members associated with the complex nature of damage in these materials has been a limiting factor. Generally, a number of failure modes operate simultaneously at a site of damage, and each of these failure modes generates a different type of acoustic emission signal. In addition, issues …

Stakeholders’ Perceptions Regarding Zero Tolerance And Disproportionate Exclusions Of African-American Male Students, Bertha Kornegay Dixon

Use Of Sweet Potato To Develop A Medium For Cultivation Of Lactic Acid Bacteria, Saeed A. Hayek

Dissertations

This study investigated the use of sweet potatoes (Ipomoea batatas) as a basic component to develop a medium for cultivation of lactic acid bacteria (LAB). Extract from baked sweet potatoes was used to form a sweet potato medium (SPM). SPM was supplemented with 4 g/L of each nitrogen source (beef extract, yeast extract, and proteose peptone #3). Lactobacilli MRS was used as a control medium. Ten LAB strains were used to determine the suitability of SPM serving the growth of LAB. Our results showed no significant (p < 0.05) differences in the optical density, maximum specific growth rates, and bacterial populations between MRS and SPM. SPM also maintained higher pH values throughout the incubation period compared to that in MRS. The cost of SPM was 47% less than the cost of MRS. Further step was taken to determine the suitability of SPM serving LAB enzymatic activity. LAB strains growing in SPM showed relatively higher β-glucosidases, acid phosphatase, and phytase activities and lower a-glucosidase compared to that in MRS. Strains of L. reuteri showed the …

A Neurophysiologic Study Of Visual Fatigue In Stereoscopic Related Displays, Hanniebey Dolphyne Nutung-Wiyor

Dissertations

Two tasks were investigated in this study. The first study investigated the effects of alignment display errors on visual fatigue. The experiment revealed the following conclusive results: First, EEG data suggested the possibility of cognitively-induced time compensation changes due to a corresponding effect in real-time brain activity by the eyes trying to compensate for the alignment. The magnification difference error showed more significant effects on all EEG band waves, which were indications of likely visual fatigue as shown by the prevalence of simulator sickness questionnaire (SSQ) increases across all task levels. Vertical shift errors were observed to be prevalent in …

Relationship Between Trust And Perceived Value Of Faculty Unionization Among Full-Time Faculty In Selected Michigan Community Colleges, Stacy L. Horner

Dissertations

Problem Statement. There are conflicting studies on the relationship between the union and nonunion faculty and trust. Studies have shown that the union environment inherently produces a distrustful atmosphere and, with a union, employees are actually more dissatisfied than their nonunion counterparts. On the other hand, this has created a cycle where faculty may not trust administration, and administration may not trust faculty. For example, when doing negotiations, each party fights on behalf of itself, instead of fighting for the betterment of the organization. However, unions can give faculty a voice with administration and state and federal government, and may …

Are Women Aware? : Factors Related To Women's Knowledge Of Risk And Preventive Factors In Breast Cancer, Sandra M. Walther

Dissertations

Problem. Women have a one-in-eight chance of being diagnosed with breast cancer in their lifetime. In the past decade, there has only been a decrease of less than 1% in breast cancer morbidity and mortality rates. Breast cancer continues to be a feared disease that ravages even its survivors, and grips many with fear. Furthermore, breast cancer remains the highest cost of care among cancers. In 1990 the overall cost of care for breast cancer was $4.2 billion. In 2010, the total cost of breast cancer care rose to almost $17 billion, and by 2020 the cost trends show …
