Ethnicity, Issue Voting, And Regime Change In The Gambia; Why Did Yahya Jammeh Lose The 2016 Presidential Election? The Dawning Of Dawning Democracy In The Gambia., Alieu Sanneh

Dissertations

ABSTRACT

In the 2016 presidential election in The Gambia, the opposition coalition party had successfully managed to overthrow an authoritarian government, which has ruled the country for 22 years. Contrary to the notion of the prevalence of ethnic voting in African elections, this study found that ethnicity is not the only issue influencing the voting behavior of Gambian voters. The concerns voters have on human rights abuses by the Jammeh’s admistration has resulted in a regime change. The election was issue-based, even though Gambian voters were split on the question of the economy, their dissatisfaction on Jammeh handling of human …

Conceptualizations Of Teaching In The Higher Education Classroom, Molly Flavin Broere

Dissertations

Adopting A Systematic Approach To Tasting Cider Within The Irish Craft Cider Industry, Richie Brady

Dissertations

Craft cider-makers produce less than 1% of Irish cider which is a significantly smaller percentage than craft producers in other beverage markets. This study contextualises Irish cider’s importance by exploring its rich history in Gaelic and Georgian Ireland. It then examines how that importance is not reflected in today’s market and posits that introducing a new systematic approach to tasting will enable cider to be viewed beyond what many see as a cheap, simple summer drink. A systematic approach to tasting is a structured and repeatable method of describing taste using a lexicon of agreed words. Unlike other drinks, such …

Understanding The Role Of Lipids Derived From The Gut Microbes In A Mouse Model Of Obesity-Induced Peripheral Pain, Raiza Rafael-Bonomo Hardy

Dissertations

The increase in obesity has been accompanied by a rise in the prevalence of painful peripheral neuropathy. Recently, studies have suggested a role for gut microbiome in the development of some peripheral pain, including chemotherapy- induced pain and fibromyalgia. In the present dissertation, we showed that modulation of gut microbiome in obese mice alleviated neuropathic indices, concurrent with changes in immune cell profile within the peripheral nerve system. We demonstrated that fecal transplantation from lean to obese mice decreased obesity-induced pain and restored nerve density in the skin. These improvements were accompanied by changes in peripheral nerve system gene expression, …

Exploring School Psychologists' Perceived Preparedness, Self-Efficacy, And Motivations For Practice In Urban Schools, Kiley Callahan

Dissertations

The fundamental goal of school psychological service delivery is to enhance the learning and mental health of all students, regardless of their school setting. However, there is evidence to suggest that school psychologists' professional needs and experiences may differ based on the context in which they work. The urban school context, in particular, is associated with several challenges that may impact school psychology practice, including the impact of systemic barriers, systematic marginalization of children and families, and limited resources. To better prepare school psychologists to support urban learners, efforts to understand their training needs must be prioritized. Still, the views …

Reams, Radicals And Revolutionaries: The 'Illinois Staats-Zeitung' And The German-American Milieu In Chicago, 1847-1877, Sebastian Peter Wuepper

Dissertations

This dissertation analyzes how a large, German-language newspaper, the Illinois Staats-Zeitung served the German-American immigrant community in Chicago in the second half of the nineteenth century. The German diaspora in the United States was not a secluded, separated, and isolated entity, but a node in a transnational network of cultural exchange that crossed national and natural boundaries. Newspapers contributed significantly to the creation and maintenance of this cultural sphere. The editors of the Staats-Zeitung were refugees of the failed 1848 democratic revolutions in Germany. In Germany they had been academics, intellectuals, lawyers and journalists. They brought their political convictions with …

Secure Data Integrity In Wireless Ad Hoc Networks, Elbasher O Esalmi Elmahdi

Dissertations

Wireless ad hoc networks (WANETs) have become increasingly popular in our everyday business and personal lives. As long as nodes in the network belong to the same organization and share the same goal, it can generally be expected that all nodes can be trusted. So, without any security measures in place, any node is capable of compromising the integrity of the data it forwards. It is necessary to save or secure data transmission in WANETs to achieve effective communication because most of the routing protocols proposed for WANETs assume a trusted and reliable environment and they do not consider the …

Improved Isosurfacing Through Compression And Sparse Grid Orientation Estimation, Brian Wood

Dissertations

This dissertation focuses on increasing isosurfacing speed through novel compression approaches. The compression occurs on a cell-by-cell basis during isosurface extraction, as opposed to compressing the mesh in a post-processing step. The compression is applied to isosurfacing on cluster computers, and it postpones scalability plateauing of prior parallel isosurfacers by reducing communication on cluster computers (versus the prior state of the art). A novel view-dependent isosurface mesh decompressor and improved isosurface orientation estimator for sparse datasets via quadratic splines fit to tetrahedral decompositions of the datasets are also described. Experimental results for all efforts, which quantify their effectiveness, are also …

Characterizing Galectin And Lysosomal Rupture's Role In Spreading Parkinson Disease Pathology, Kevin Burbidge

Dissertations

The misfolding and subsequent accumulation of alpha-synuclein (α-syn) is central to the pathogenesis of Parkinson's disease (PD). Several lines of evidence suggest pathological α-syn spread cell-to-cell via a "prion-like" mechanism. Furthermore, this pathological α-syn is capable of "seeding" further misfolding of non-pathological α-syn, converting them to the pathological form. While a vast body of both genetic and experimental evidence indicates that α-syn is critical to PD development, how α-syn induces progressive neuronal dysfunction and cell death remains unclear.Autophagy, conventional for macroautophagy, is the primary degradation pathway for α-syn aggregates. Autophagy also influences the unconventional secretion of both pathological and non-pathological …

Performance Comparison Between A Distributed Particle Swarm Algorithm And A Centralised Algorithm, Ciarán O’Loughlin

Dissertations

Particle Swarm optimisation (PSO) is a particular form of swarm intelligence, which itself is an innovative intelligent paradigm for solving optimization problems. PSO is generally used to find a global optimum in a single optimisation function. This typically occurs on one node(machine) but there has been a significant body of research into creating distributed implementations of the PSO algorithm. Such research has often focused on the creation and performance of the distributed implementation in an isolated manner or compared to different distributed algorithms.

This research piece aims to bridge a gap in the existing literature, by testing a distributed implementation …

Effects Of Altering Variable, Basic Residues Of Ribosomal Proteins Ul4 And Ul22 Facing The Ribosomal Exit Tunnel On Growth, Resistance,And Gene Expression In Escherichia Coli: Focus On Ul22 K90d, Elizabeth A. Franklin

Dissertations

Mutational changes in bacterial ribosomes that confer antibiotic resistance decrease cell fitness. Determining the genetic factors that interconnect antibiotic resistance and cell fitness is critical in the fight against bacterial infections. This study describes gene expression and phenotypic changes presented in Escherichia coli cells carrying a uL22 K90D mutant ribosomal protein, which showed growth defects and resistance to macrolide antibiotics. Other uL4 and uL22 mutation, in basic, non-conserved residues, were examined for phenotypic changes, however the uL22 K90D mutation displayed the most consistent phenotypes when compared to the wild type strain, and thus was the focus of this study. Ribosome …

These results show significant differences between kqueue and epoll, and a profound impact of virtualisation as a variable.

Disrupting The School-To-Prison Pipeline: A Mixed-Methods Systematic Review Of Alternative Discipline Practices To Reduce Exclusion And Promote Equity, Cara Diclemente

Dissertations

Zero tolerance policies were designed to create safety by implementing automatic exclusion (e.g., suspensions, expulsions) for misbehavior in response to rising school violence in the United States. However, evidence over the past four decades shows that these policies fail to increase objective and subjective safety, and instead foster poor school climate and disproportionate rates of minority groups in the school-to-prison pipeline. Previous research and literature reviews suggest there are a host of developing Multi-Tiered System of Supports (MTSS) practices that have promising potential to reduce exclusionary outcomes and foster equitable treatment of vulnerable student populations, such as Positive Behavioral Intervention …

Verification And Validation Methods For Extended Petri Nets Modeling Cyberattacks, Walter Alan Cantrell

Dissertations

Verification and validation are crucial to establishing the credibility of the results of a modeling and simulation project. Conclusions drawn from an unverified and unvalidated model are at best unconvincing, and at worst have the potential to be dangerous if decisions are made based on outputs from an incorrect model. In general, the most effective methods of verification and validation involve comparisons of simulation results with data from observations of the system or event being simulated. However, such methods cannot be used if system data is not available. This is often true of cyberattacks, because the victims of cyberattacks conceal …
