Surviving The Presidency: Presidential Failures In South America, Christopher A. Martinez

Dissertations

Since 1979, one out of six South American presidents have failed to complete their terms of office. These "failed presidencies" occur when democratically elected presidents are forced to leave office early, but without compromising the democratic order. This dissertation seeks to solve the puzzle of what drives presidents out of office. Previous studies have found that institutional and political factors, economic issues, and social mobilizations are powerful forces affecting presidential failures. In this research, I examine the impact these factors have on the likelihood of presidential failures.

Additionally, I argue that previous works have failed to find a significant relation …

Not The Whole Story: Narrative Responses To Contemporary Globalization, Sean Patrick O'Brien

Dissertations

This dissertation analyzes contemporary global fiction in English (and, in one chapter, new media literatures such as videogame-based narratives) to examine how individuals, communities, and globalized networks manage differences among historical interpretations, ideologies, lived experiences, and cultural and national traditions making competing demands. Cultural and media theorists like John Tomlinson, Anthony Giddens, Arjun Appadurai, Lev Manovich, and Ian Bogost have demonstrated the overwhelming complexity of life in an age of accelerating globalization. Building on their work and the narrative theory of Maggie Dunn and Ann Morris, I explore how literary narratives employ newly prominent composite narrative structures to represent and …

Eliminating Acute Myeloid Leukemia Stem Cells By Targeting The Niche Microenviromnent: Co-Inhibition Of Tnf/Il1- Jnk And Nf-Κb, Andrew Volk

Dissertations

Leukemia Stem Cells (LSCs) from Acute Myeloid Leukemia (AML) require the activity of the transcription factor NF-kB to maintain stemness and drive tumor formation. Blocking NF-kB can preferentially eliminate LSCs in vitro with minimal effects on healthy Hematopoietic Stem and Progenitor Cells (HSPCs), making NF-kB a compelling target for anti-leukemia therapies. However, blocking NF-kB in vivo can only extend survival for a short period of time before transplanted mice succumb to the disease. I propose this is due to components of the in vivo niche supporting LSC survival and compensating for the inhibition of NF-kB.

I observed patients with partially …

Negotiating Diabetes: Professional Diabetes Care Work In The U.S., Melissa Marie Gesbeck

Dissertations

The rising incidence of diabetes mellitus (types 1 and 2) transcends national borders, creating a global pandemic. The U.S. leads the world in diabetes prevalence, despite its wealth and access to sophisticated medical technologies. Within health care, there is an increasing focus on lifestyle and behavioral interventions that research suggests may be the key to reversing this trend, but thus far their effectiveness in practice is uneven at best. In order to gain a better understanding of the other factors involved in professional diabetes care work that might support or inhibit effective diabetes management, this research treats diabetes as a …

Exploring The Impact Of Mindfulness On Adolescents: A Mixed Methods Approach, Poonam Desai

Dissertations

As social emotional learning gains greater focus, identifying effective interventions for high-risk students, such as students with Emotional/ Behavioral Disorder (EBD), becomes a priority. Mindfulness, as an intervention, offers a unique set of skills to increase emotional awareness and regulation, while also teaching key social emotional skills (Singh et al, 2007). Mindfulness, or the nonjudgmental observation of one's thoughts, feelings, and emotions, has roots in Buddhist philosophy, but is used secularly in the fields of psychology, medicine, and education (Baer, 2003). In this mixed methods study, the researcher aims to examine the experiences of adolescents who have EBD at an …

Incapacitated Fatherhood: The Impact Of Incarceration On African American Fathers, Dara Lewis

Dissertations

This project examines the ways that incarceration can shape the meaning and performance of fatherhood. Using 109 surveys and 30 in-depth interviews, three dominant themes emerged that constitute a model father identity standard: 1) being there for their children; 2) being an example for their children; and 3) providing their children with love, basic needs, and protection. The findings indicate that prison environment and post-incarceration restrictions do not support fathers’ ability to perform their roles as fathers, or the maintenance of healthy relationships between fathers and their children. Specifically, it disrupts the father identity confirmation process. As a result, relational …

Growing Diversity: Urban Renewal, Community Activism, And The Politics Of Cultural Diversity In Uptown Chicago, 1940-1970, Devin Hunter

Dissertations

“Growing Diversity: Urban Renewal, Community Activism, and the Politics of Cultural Diversity in Uptown Chicago, 1940-1971” examines the development of one of the nation’s most culturally and economically diverse neighborhoods. This character resulted from a historical process centered on the shifting politics of cultural diversity itself. Boosters, urban renewal and redevelopment advocates, community activists, and low-income residents defined diversity on their own—often competing—terms. These dynamics manifested in urban planning and architecture, working-class and middle-class leisure, radical community organizing, and film. Beyond the demographic development of social and economic heterogeneity, “Growing Diversity” traces the ways that historical processes influenced the ways …

Gender-Homogenous Mentoring, Spiritual Wellbeing, And Self-Efficacy Beliefs In African American Male Adolescents: A Test Of Three Models, Toussaint David Whetstone

Dissertations

Many African American male adolescents mature without the influence of an adequate social model, or a positive, same sex (or gender-homogenous) mentor. Thus, it may be difficult for African American male adolescents to reach adulthood having developed the perceived capability to be successful within specific domains that American society commonly associates with a healthy life course trajectory. A large body of research has suggested that vicarious experience or role modeling is a primary source of efficacy information in a variety of life domains. Research has also suggested that modeling effects are enhanced if the subject and model are similar, especially …

Women In Kazakhstan: A Multifaceted Approach To Female Political Representation, Ashley Gaile Benedict

Dissertations

This investigation focuses on two competing theories (historical institutionalism and social constructivism) and their explanatory value in regards to female political representation in Kazakhstan. Historical Institutionalism maintains that current institutional dynamics are constrained by past institutional formations, even when these past institutions are no longer relevant. Social Constructivism challenges this theory by upholding that institutions are culturally situated and a reflection of shared ideas rather than material forces as argued by historical institutionalism. Based on Hanna Pitkin’s (1967) four dimensions of representation (formal, descriptive, substantive, and symbolic), I examine how Kazakhstan’s Soviet past and its creation of a Kazakh ethnic-national …

Who Decides? A Study Of The Effects On Decision Unit Dynamics In Crisis And Crisis Transition, Janet Leigh Drake

Dissertations

Foreign policy decision-making is often an obscured process, particularly when it involves threats to national security or national interests. Despite the lack of transparency, though sometimes necessary, foreign policy decisions can have far-reaching consequences. Policymakers establish and affect relationships with other governments, and can commit state resources for cooperation or for conflict. The purpose of this study is to determine what types of decision units make foreign policy decisions and what factors influence the dynamics of the unit. I employ the decision units (DU) framework developed by Margaret Hermann to decisions made by the United States and Israel during the …

The Role Of Violence Within And Across Self-Identified Gang Youth, J. Michael Vecchio

Dissertations

Whether actual (i.e., direct and vicarious victimization) or anticipated (i.e., fear of crime and perceived risk of victimization) violence, gang youth commonly discuss violence in terms of having an important role in both their gang experiences and daily lives. In particular, violence can play an important role within the specific stages of the gang experience – 1) joining, 2) active membership, and 3) leaving. This includes the importance of protection from violence as a common motivator for joining, the utility of violence as a means of building cohesion between active gang members, as well as the importance of exposure to …

Family-Of-Origin Characteristics Of Men Who Engage Regularly In Sexually Addictive Behavior, Mark Stephen Pfuetze

Dissertations

The present study surveyed men to assess whether any correlations existed between a man’s sexually addictive behavior and how his family-of-origin addressed sexuality along with demographic factors. A total of 374 male participants (18 years or older) provided complete data sets via the online survey located on SurveyMonkey. The main research question for this study was as follows: Is there a relationship between demographic variables or family factors: (a) negative attitudes and communication about sexuality in one’s family-of-origin, (b) exposure to sexual stimuli in one’s family-of-origin, and (c) open sexual discussion in one’s family-of-origin, and sexual addiction. All three of …

From Teachers' Control Of Curricula To Curricula's Control Of Teachers: An Analysis Of Loss Of Autonomy In The Lnstructional Labor Process, Joseph Daniel Abbott Jr.

Dissertations

This dissertation explores how the labor process of public school teaching, a white-collar profession, is deskilled. In a content analysis of English/language arts teacher’s manuals and teacher’s editions of student textbooks, I examine public school teachers’ degree of autonomy from an objective, macro-analytical perspective. Applying Harry Braverman’s (1974) theory of the degradation of the modern worker under monopoly capitalism, I explain how teacher deskilling reflects structural factors in the work context that prevent teachers from accessing their professional and personal skill sets via the separation of conception and execution in the instructional labor process.

The formal curricula drive the teaching …

Aminoglycoside-Induced Otoneurotoxicity: Analysis Of Inner Hair Cell Synaptic Plasticity Following Drug Exposure, Matthew M. Abernathy

Dissertations

Aminoglycoside antibiotics are powerful drugs for combating bacterial infections, but are limited in use due to their ototoxicity. This class of drug targets the auditory hair cells of the cochlea, causing cell death, which leads to a decline in auditory function. In spite of much research aimed at revealing a mechanism of damage, there are no co-therapies available to diminish the ototoxic liability of aminoglycosides. Existing research does show that there may be a neurodegenerative process that contributes to the observed toxicity. In an effort towards clarifying present understanding of issue, this dissertation project was conducted to characterize the neurodegenerative …
