Europe’S Refugee Crisis: Assessing The Factors Preventing A Coordinated Eu Response, Ali Albassam

Master's Theses

In order to escape increasing political violence in the Middle East and Africa, many refugees are fleeing by sea to seek asylum in Europe. As a result, Europe has witnessed the highest influx of refugees since World War Two. European Union member states have scrambled for a solution, seemingly unable to form a collective response. The reemergence of nationalism amid the arrival of thousands of refugees not only clouds Europe’s moral compass, but also weakens the EU and its founding principles. In an effort to contribute to the protection of refugees and the EU and its values, this thesis aims …

Characterizing The Role Of Sialylated Milk Glycans And The Infant Gut Microbiota In Growth And Metabolism, Mark Richard Charbonneau

Arts & Sciences Graduate Student Theses and Dissertations

Undernutrition is a pressing and pervasive global health problem. The pathogenesis of this disease remains unclear, but epidemiologic studies indicate that it is not due to food insecurity alone. Moreover, current therapeutic interventions have limited efficacy in preventing or ameliorating the long-term sequelae of undernutrition, including stunting and cognitive deficits. Recent culture-independent studies have demonstrated that the normal postnatal pattern of gut microbiota development is disrupted in children with undernutrition, leading to the proposal that perturbations in gut microbiota development impairs healthy growth of the host. Human breast milk contains a diverse repertoire of free and conjugated human milk oligosaccharides …

Collective Action Dynamics In Urban Neighborhoods: A Study Of Urban Community Gardens, Nishesh Chalise

Arts & Sciences Graduate Student Theses and Dissertations

Lessons from various policies and programs both in the United States and international development have led to a knowledge base concluding that an engaged community is a critical component for developing a thriving community. This is based on a premise that even in the modernized world community still has a role to play along with government and the market in their own development. Community’s role is further highlighted in areas such as low-income urban neighborhoods where both the government and the market may not be able to fulfill all the needs.Research has followed by trying to understand why people engage …

Understanding The Nano- And Macroscale Processes Impacting Arsenic Mobilization During Managed Aquifer Recharge Using Reclaimed Wastewater, Chelsea Wren Neil

McKelvey School of Engineering Graduate Student Theses & Dissertations

Managed aquifer recharge (MAR) utilizing reclaimed wastewater is a vital means of replenishing natural freshwater supplies in order to meet growing demands. Unfortunately, this process has been found to induce unfavorable geochemical reactions which mobilize arsenic from aquifer sediments. This process is further complicated by the simultaneous formation of iron(III) (hydr)oxide secondary minerals, which can sorb aqueous arsenic. It is crucial to fully elucidate these physico-chemical processes in order to establish safe MAR operations which minimize arsenic release. Thus, the mechanisms controlling arsenic release from arsenopyrite during MAR were investigated from the nano- to macroscale.

First, nanoscale iron(III) (hydr)oxide nucleation …

Investigating The Complexity Of Impact Crater Ejecta, Michael Raymond Zanetti

Arts & Sciences Graduate Student Theses and Dissertations

The formation of an impact crater ejecta blanket can be viewed as a form of organized chaos. Material that is ejected from a crater is heavily brecciated, but falls back to the surface along ballistic trajectories, generally preserving an inverted sense of the original stratigraphy. As the ejecta re-impacts the area surrounding the crater it forms a thick blanket of ejected material and reworked target surface that gradually thins away from the crater rim. Within the crater, crater modification processes, such as wall terrace formation and impact melt drainage, transform the crater in expectable ways. The approach adopted in this …

Applying Bayesian Machine Learning Methods To Theoretical Surface Science, Shane Carr

McKelvey School of Engineering Graduate Student Theses & Dissertations

Machine learning is a rapidly evolving field in computer science with increasingly many applications to other domains. In this thesis, I present a Bayesian machine learning approach to solving a problem in theoretical surface science: calculating the preferred active site on a catalyst surface for a given adsorbate molecule. I formulate the problem as a low-dimensional objective function. I show how the objective function can be approximated into a certain confidence interval using just one iteration of the self-consistent field (SCF) loop in density functional theory (DFT). I then use Bayesian optimization to perform a global search for the solution. …

Copper And Zinc Oxide Composite Nanostructures For Solar Energy Harvesting, Fei Wu

McKelvey School of Engineering Graduate Student Theses & Dissertations

Solar energy is a clean and sustainable energy source to counter global environmental issues of rising atmospheric CO2 levels and depletion of natural resources. To extract useful work from solar energy, silicon-based photovoltaic devices are extensively used. The technological maturity and the high quality of silicon (Si) make it a material of choice. However limitations in Si exist, ranging from its indirect band gap to low light absorption coefficient and energy and capital intensive crystal growth schemes. Therefore, alternate materials that are earth-abundant, benign and simpler to process are needed for developing new platforms for solar energy harvesting applications.

Science And Nature In The Medieval Ecological Imagination, Jessica Rezunyk

Arts & Sciences Graduate Student Theses and Dissertations

This dissertation explores the intersections between nature and culture in medieval literature and art with particular focus on Geoffrey Chaucer’s House of Fame, the thirteenth-century French Bible Moralisée (Vienna, Österreichische Nationalbibliothek Codex Vindobonensis 2554), and William Langland’s Piers Plowman. Current academic paradigms tend to place the study of nature firmly within the sciences and the study of culture firmly within the humanities, creating a gap between the fields that effectively isolates their respective methodologies and vocabularies from one another. This dissertation seeks to bridge that gap between the sciences and the humanities by approaching medieval literature through the lens of …

Investigation Of 89zr-Siderophores As Molecular Imaging Agents For Positron Emission Tomography Imaging Of Bacterial Infections, Nora C. M. Goscinski

Arts & Sciences Graduate Student Theses and Dissertations

Siderophores are small molecules synthesized by bacteria to harvest Fe³⁺ from their environment. In infection scenarios, their production can increase infection virulence by increasing the ability of bacteria to obtain Fe³⁺ and therefore grow more rapidly. The selective uptake of siderophores in vivo in multi-bacteria environments indicates that this class of molecules has a potential use as selective imaging agents. In this work, DFO-NCS and a library of trihydroxamate siderophores were evaluated as vehicles to deliver ⁸⁹Zr selectively to bacteria for Positron Emission Tomography (PET) imaging of bacterial infections. Productive work with radiometals involves thorough knowledge of …

The Role Of Trauma And Mental Health Problems In The Perpetration Of Intimate Partner Violence In Post-Genocide Rwanda, Sarah Myers Tlapek

Arts & Sciences Graduate Student Theses and Dissertations

Exposure to political violence or war is associated with intimate partner violence (IPV) in post-conflict settings (Clark et al., 2010; Gupta, Reed, Kelly, Stein, & Williams, 2012), and civilians and veterans who develop posttraumatic stress disorder (PTSD) after exposure to combat or violence are more likely to perpetrate violence against an intimate partner (Taft, Watkins, Stafford, Street, & Monson, 2011). Rwandan health professionals estimate that after the 1994 genocide more than one-quarter of the country’s population now suffers from PTSD (Munyandamutsa, Nkubamugisha, Gex-Fabry, & Eytan, 2012). Although the majority of Rwandan women (56%) have experienced IPV in their lifetime (National …

National Narratives, Comparative Moves: Tracing Literary Connections Between Anglophone Postcolonial Literatures And Modern Turkish Literature, Aysegul Turan

Arts & Sciences Graduate Student Theses and Dissertations

This dissertation examines Anglophone postcolonial literatures and modern Turkish literature through their representations of the idea of empire and the nation-state. By employing a comparative framework that brings together Anglophone postcolonial literatures and modern Turkish literature, this project strives to relocate the focus of postcolonial discourse from the colonizer-colonized divide to a broader frame of uneven power relations, both past and present. In doing so, it examines paradigms such as the independence struggle, the nation-state, and modernization that are vital to an understanding not only of the imperial past but also of the global present. The Anglophone postcolonial canon and …

Betting On Empire: A Socio-Cultural History Of Gambling In Late-Qing China, En Li

Arts & Sciences Graduate Student Theses and Dissertations

This dissertation uses the practice and licensing of gambling, especially the lotteries, to investigate social, intellectual, and geo-political changes in the transitional period of late-Qing China. This research begins with a study of a civil service examination scandal in 1885. A highly organized lottery scheme, where money was bet on surnames that would pass the state’s official selection examinations, spurred manipulation of the examination results. Based on current sources and agreeing with resent studies on public institutions in late-imperial China, I conclude that, the lottery contributed to a more inclusive public by providing people with simultaneous experiences across time and …

Micro-Determinants Of Income Inequality And Consumption In Rural Bangladesh, S Rahman

School of Engineering, Computing and Mathematics

The paper examines the extent to which household and regional characteristics influence income inequality and consumption/welfare based on an in-depth survey of 406 households from 21 villages in three regions of Bangladesh. Results show that the overall Gini coefficient for rural incomes is 0.43 but Gini-decomposition revealed that the contribution of mixed crop production to inequality is just 10 percent while “Green Revolution” technology contributes almost 29 percent. Land ownership, farm capital assets, modern irrigation, non-agricultural income, and household head”s education significantly increase consumption. Tenants and households with more dependents are doubly disadvantaged and consume significantly less. Regional factors also …

Human Immunodeficiency Virus Type 1 Envelope Protein Interaction With Host Cell Coreceptor C-X-C Chemokine Receptor Type 4, Jie Zhang

Arts & Sciences Graduate Student Theses and Dissertations

Human Immunodeficiency Virus Type 1 (HIV-1) envelope protein is the sole determinant for viral entry and tropism. The ability of HIV-1 to infect susceptible host cells depends on the ability of its envelope protein to engage host cell receptor CD4 and coreceptor C-C Chemokine Receptor Type 5 (CCR5) and/or C-X-C Chemokine Receptor Type 4 (CXCR4). Most naturally occurring infections start with a single CCR5-tropic virion. In approximately 50% of HIV-1 Clade B infected patients, the viral population spontaneous develops the ability to utilize CXCR4 at a late disease stage, and this coreceptor shift corresponds to a poor prognosis for the …

Exploring The Concepts Of Traditional Inuit Leadership And Effective School Leadership In Nunavut (Canada), Jane P. Preston, Tim R. Claypool, William Rowluck, Brenda Green

Comparative and International Education / Éducation Comparée et Internationale

The purpose of this paper is to document how educators living in Nunavut communities describe traditional Inuit leadership and effective school leadership. The data for this qualitative study were 24 semi-structured interviews, involving 14 teachers, vice-principals, and principals from Nunavut. Findings revealed that traditional Inuit leadership was about promoting the personal leadership skills, interests, and/or abilities of each community member, and it often involved Elders who fostered the linguistic, social, cultural, and spiritual wellness of students and school staff. Participants depicted an effective school leader to be someone who promoted teamwork. Also, participants indicated that effective school leaders were community …

Antisense Rna-Mediated Epigenetic Regulation Of Brain-Derived Neurotrophic Factor., Roya Pedram Fatemi

Open Access Dissertations

Long noncoding RNAs (lncRNAs) regulate chromatin remodeling through their interactions with epigenetic enzymes during development and disease. The inhibition of the natural antisense transcript of Brain-derived neurotrophic factor (BDNF-AS), results in BDNF promoter de-repression and transcriptional upregulation, both in vitro and in vivo. Recently, we showed that BDNF-AS interacts with the histone methyltransferase enhancer of zeste homolog 2 (EZH2) to suppress BDNF mRNA and protein expression. BDNF is an important neurotrophin that is required for neural development and maintenance of the nervous system. Dysregulation of BDNF occurs in a number of neurological disorders, including: Alzheimer’s Disease, Parkinson’s Disease, Rett syndrome, …

Sparse Representation And Dictionary Learning For Biometrics And Object Tracking, Rahman Khorsandi

Open Access Dissertations

Biometrics attracted the attention of researchers in computer vision and machine learning for its use in many applications. We propose systems for face and ear recognition, gender classification and object tracking. First, we present a fully automated system for recognition from ear images based upon sparse representation. In sparse representation, extracted features from the training data is used to develop a dictionary. Classification is achieved by representing the extracted features of the test data as a linear combination of entries in the dictionary. In fact, there are many solutions for this problem and the goal is to find the sparsest …

Comparison Of Beginning Teachers' And Experienced Teachers' Readiness To Integratetechnology As Measured By Tpack Scores, Heather S. Fontanilla

Dissertations

Despite a growing awareness of the importance of technology in education, increased investment and attention to preparing teachers to integrate technology into the classroom, research shows that technology continues to fail to live up to its potential for transforming education. As schools move from standards based testing to implementation of the Common Core State Standards (CCSS), an expectation exists that teachers will be using technology to transform their teaching practices. There is also an expectation that schools are providing students with 21st century skills, including the use of technology. In exploring the reasons teachers are not using technology effectively, much …

The Female Perception Of Safety On A College Campus, Kimberly N. Miles

Mahurin Honors College Capstone Experience/Thesis Projects

Previous research has shown the prevalence of females on college campuses across the nation experiencing a generalized fear of being victimized or violently assaulted while on campus. This fear is generated by the knowledge of violent crimes towards women on campus, as well as the perception alone that there are assaults happening on campus. Studies have noted that this fear held by female students can significantly affect their academic progress and overall wellbeing while at school. This study chose to examine the female students of Western Kentucky University and their personal perception of safety on college campuses comparing students who …

Backwards In High Heels: Examining The Careers And Artistic Contributions Of Fred Astaire’S Female Dance Partners, Fiona Mowbray

Mahurin Honors College Capstone Experience/Thesis Projects

This project examines the careers and contributions of three of Fred Astaire’s female dancing partners during the golden age of movie musicals: Ginger Rogers, Vera-Ellen, and Cyd Charisse. These women receive less recognition than their male co-star, due in part to the political and social environment from the 1930s to the 1950s in America, sexism and competition within Hollywood, and personal obstacles. Rogers, Vera-Ellen, and Charisse are all important as individual performers as well as for the part they played in enhancing Astaire’s legacy. My goal is to bring these women back into the musical theatre narrative in a compact …

Puerto Rico’S Community Health Centers In A Time Of Crisis, Peter Shin, Jessica Sharac, Marie Nina Luis, Sara J. Rosenbaum

Geiger Gibson/RCHN Community Health Foundation Research Collaborative

In 2014, Puerto Rico’s twenty federally funded community health centers, operating in 71 sites located throughout the Commonwealth, served 330,736 patients, approximately one in ten Commonwealth residents. Compared to other Puerto Rico residents, health center patients are less likely to be insured. Despite considerable growth in Medicaid as a result of the supplemental funding provided under the Affordable Care Act, in 2014, 12.2% of health center patients remained uninsured.

Compared to health centers outside Puerto Rico, Puerto Rico’s health centers show a greater proportion of Medicaid patients served (69% compared to 46% outside Puerto Rico), a greater dependence on physician …
