Barriers To Computer Programming Student Success: A Quantitative Study Of Community College Students In Southwest Missouri, Tiffany D. Ford

Dissertations

Student success in computer programming courses has been a long-studied problem and computer science major retention has historically been substantially lower than other majors. The issue of retention for computer science majors has become more pronounced in two-year, open-enrollment institutions. This quantitative study, grounded in Gardner’s theory of multiple intelligences, attempted to address some of the causes of poor retention for entry-level computer science majors at two-year colleges by looking for predictors of student success in their first computer programming course. Two of the intelligences from Gardner’s (1993) theory, Logical-Mathematical and Visual-Spatial, were used along with two factors: student success …

Regulation Of Vancomycin Resistance And Stress Response By The Msaabcr Operon In Staphylococcus Aureus, Dhritiman Samanta

Dissertations

Staphylococcus aureus is the predominant cause of public health problems around the world. Vancomycin has been an important antibiotic against Methicillin Resistant Staphylococcus aureus (MRSA) infections. However, Vancomycin Intermediate S. aureus (VISA) strains have been reported. These strains are characterized by thick cell walls, reduced autolytic rate, reduced PBP4 activity, and increased amount of D-Ala-D-Ala termini in the cell wall. In this study, we show that the msaABCR operon regulates vancomycin resistance in two clinical VISA strains. Deletion of the msaABCR operon in strains Mu50 and HIP6297 resulted in a significant decrease in the minimum inhibitory concentration (MIC) for vancomycin. …

Teacher Perceptions Of The Use Of School-Wide Positive Behavior Interventions And Supports At Reducing The Presence Of Bullying In Middle Schools, Kristine Marie Harper

Dissertations

Each day students throughout the world are exposed to bullying in many different ways and on many different occasions. Bullying has received such a great amount of attention through the media, that it leaves parents and community members with the belief that bullying has become a bigger problem today than it ever has before Austin, Reynolds, & Barnes, 2012; Carrera, DePalma, & Lameiras, 2011; Packman et al., 2005; Rigby & Smith, 2011). Nearly every state in the nation has passed laws regarding bullying and increasing the responsibility of schools and districts to implement programs to prevent and/or address bullying on …

An Analysis Of The Correlation Between Act Scores And One-To-One Computing, Jeffrey Brian Heath

Dissertations

This study examined whether a relationship exists between one-to-one computing and student achievement, specifically ACT scores. This study also examined whether relationships exist among teachers’ perceptions of one-to-one computing, teachers’ years of experience, subjects taught by teachers, teachers’ skill level in the use of a computer for instruction, and teachers’ perceptions of changes in ACT scores. The results of this study could help policymakers and educators with decisions regarding implementation of one-to-one computing programs.

Predictors Of Binge Eating In College Women, Emily E. Prather

Dissertations

Binge eating has received increased attention in the psychological literature, as the health consequences are becoming increasingly well known. The prevalence of subclinical binge eating (i.e., binge eating that is not associated with a diagnosable eating disorder) is elevated among college women, some of whom will go on to develop more serious problems. Thus, improved understanding of subclinical binge eating in this population can help to inform prevention and intervention strategies.

In a sample of 472 college women this study evaluated the relationships among four theoretically relevant factors hypothesized to predict binge eating: trait anger, anger suppression, impulsivity, and emotion …

Understanding Mechanistic Details Of Neuroinflammatory Pathways Stimulated By The Alzheimer's Disease Amyloid-Beta Protein, Shana Usery

Dissertations

Alzheimer’s disease (AD) is characterized by neuroinflammation. Senile plaques composed of aggregated amyloid-β protein (Aβ) are found in AD patients’ brains. The Aβ is formed by the proteolytic cleavage of the amyloid precursor protein (APP) resulting in Aβ fragments that are 39-42 amino acids in length. The two most common peptides are Aβ(1-40) and Aβ(1-42), which differ by two amino acids, isoleucine and alanine. Within the brain of AD patients, Aβ monomer self-assembles to form several aggregate morphologies, including oligomers, protofibrils, and fibrils. Activated microglial cells and associated secreted proinflammatory cytokines surround these plaques producing a localized inflammatory environment in …

Hometown Influence: The Impact Of Geography On Statewide Candidate Emergence And Success, Cassie A. Myers

Dissertations

The purpose of this study is to explore whether statewide geography influences a candidate’s electoral position. More specifically, what role does geography play in candidate emergence and success on the statewide level? Conventional wisdom holds that geography does matter in candidate emergence and success. Beyond the anecdotal, however, there has been little research in this area. I theorize that general attitudes about rural identity and, conversely, urbanity affect electoral outcomes based upon the population composition of the state. To explore these questions, I created a typology characterizing states as rural or urban, based upon an index capturing rural cultural and …

Talk And Deterrence In Drug Markets, Timothy Dickinson

Dissertations

Despite a wealth of conceptual and empirical examinations, key processes occurring during each of the primary stages of deterrence remain poorly specified. Little is known about how potential offenders form their perceptions of rules or threats, and the relationship between these perceptions and fear has only received moderate attention. In addition, many questions remain regarding how offenders eliminate or reshape punishments after violating rules. In this dissertation I examine how various forms of talk shape these processes. More specifically, I investigate how gossip influences offenders’ perceptions of rules or threats, how humor and threats and promises moderate the fear stemming …

The Schoolyard As An Outdoor Classroom: Learning Through Experience, Jason W. Spray

There were 248 fifth grade African-American students (N = 248) who participated in the research study. Students responded to a pre- and post-assessment to measure knowledge …

Educational Entrepreneurship As Reform Strategy For St. Louis Public Schools From 2003 To 2009, Nathalie Henderson

Dissertations

“Educational Entrepreneurship” has increasingly become a buzz word, theory of change, silver bullet for countless so called education reformers who look to fix urban education by allowing alternative routes to teacher certification, public- private partnerships and the creation of charter schools. I have chosen autoethnography to highlight critical events from my own professional experience to illustrate the effects of educational entrepreneurship on The St. Louis Public Schools. This study used critical race theory as a lens to probe my narrative not only as a participant in educational entrepreneurship but also as Black, female educator. The end result is a reflective …

Paradigm Transformation: Preparing Students For The Transition To Middle School, Lasabra Warner Patterson

Dissertations

This Change Leadership Plan is the second part of a three-part dissertation on effectively transitioning students from elementary school to middle school. Currently, there is no local program to aid students in transitioning from elementary to middle school. The rationale is that by addressing the need for increased focus on improving current practices, students’ needs will be met. This is important to the school, the district, and the educational community at large in preparation for implementation of the Common Core State Standards where all learning will spiral from grade level to grade level, continually allowing students and teachers to make …

Tongues Untied Truth Revealed: Body Image, Social Media, Identity Development, And Meaning-Making In Overweight And Obese Black Gay Msm, Amari Ja-Lynn Enam

Dissertations

This phenomenological study explored the meanings attributed to internalized messages about body image within the context of identity development from the perspectives of overweight/obese men of African descent (OMAD) among a group of 6 men who have sex with men (MSM). I was interested in those messages that have been incorporated, adopted, or integrated into OMAD-MSM’s sense of self. Informants shared body image-related experiences from interactions with family, friends, dating/sex partners, and the media/social media.

Academic literature has explained identity development processes among African Americans through various lenses but research has not adequately explored the convergence of multiply oppressed social …

Structural Controls On The Distribution Of Groundwater In Southern Sinai, Egypt: Constraints From Geophysical And Remote Sensing Observations, Lamees Mohamed

Dissertations

An integrated (Very Low Frequency [VLF] electromagnetic, magnetic, remote sensing, field, and Geographic Information System [GIS]) study was conducted over the basement complex in Southern Sinai (Feiran watershed) for a better understanding of the structural controls on the groundwater flow. The increase in satellite-based radar backscattering values following a large precipitation event (date: 17, 18 Jan 2010; amount: 34 mm) was used to identify water-bearing features, here interpreted as preferred pathways for surface water infiltration. Findings include: (1) The distribution of the water bearing features (conductive features) correspond to that of fractures, faults, shear zones, dike swarms, and wadi networks; …

Citizenship, Politics And Process: A Cross National Study Of Citizenship Regimes, Marisha Lina Lecea

Dissertations

Citizenship policy is important for democracies and for the people who live in them. Citizenship status is important for the individual enjoyment of social, political and human rights, and restricting access to citizenship can hamper a state’s enjoyment of legitimacy and stability. Across democracies, citizenship policies range from no allowance for dual nationality and very onerous naturalization policies, to acceptance of dual nationality and non-capricious paths to naturalization. The question of this dissertation is what accounts for the variation in citizenship regimes across democracies?

I argue that it is domestic politics through party in power, judicial review and strength of …

Information Filtering By Multiple Examples, Mingzhu Zhu

Dissertations

A key to successfully satisfy an information need lies in how users express it using keywords as queries. However, for many users, expressing their information needs using keywords is difficult, especially when the information need is complex. Search By Multiple Examples (SBME), a promising method for overcoming this problem, allows users to specify their information needs as a set of relevant documents rather than as a set of keywords.

Most of the studies on SBME adopt the Positive Unlabeled learning (PU learning) techniques by treating the user's provided examples (denoted as query examples) as positive set and the entire data …
