Coding While Black, Kai Ajala Dupe

Theses and Dissertations

The focus on the lack of diversity in technology has become a hot topic over the last several years, with technology companies coming under fire for not being more representative of the markets that they serve. Even The White House and President Obama has made this issue of technology diversity and recruiting more women and people of color a topic of discussion hosting several events at The White House aimed at finding solutions to this issue. The issue has become so prevalent in the news recently that technology companies have been asked to publish report cards disclosing the demographic breakdown …

Hydrogen Sulfide Regulation Of Kir Channels, Junghoon Ha

Theses and Dissertations

Inwardly rectifying potassium (Kir) channels establish and regulate the resting membrane potential of excitable cells in the heart, brain and other peripheral tissues. Phosphatidylinositol- 4,5-bisphosphate (PIP2) is a key direct activator of ion channels, including Kir channels. Gasotransmitters, such as carbon monoxide (CO), have been reported to regulate the activity of Kir channels by altering channel-PIP2 interactions. We tested, in a model system, the effects and mechanism of action of another important gasotransmitter, hydrogen sulfide (H2S) thought to play a key role in cellular responses under ischemic conditions. Direct administration of sodium hydrogen sulfide (NaHS), as an exogenous H2S source, …

Health Aid In Africa: Placement, Service Utilization, And Benefit, Carrie Dolan

Theses and Dissertations

While the health sector has attracted significant foreign aid, evidence on the effectiveness of this support is mixed. This dissertation examines the allocation of health aid within the context of placement, service utilization, and benefit. The first paper examined the sub-national allocation of Chinese development aid projects across Africa. I determined how political preferencing of Chinese aid specifically, allocating aid to the birth region of the current political leader differs across sectors such as health, education, and transportation. I find some evidence that aid, more broadly defined, is subject to political preferencing in recipient countries, which could potentially limit its …

Renewable Carbon From Lignin Biomass And Its Electrode And Catalyst Applications In Batteries, Supercapacitors, And Fuel Cells, Muslum Demir

Theses and Dissertations

Over the last century, almost all of the carbon materials developed for the energy industry are derived from fossil fuels. The growing global concerns about energy needs, fossil fuels consumption, and the related environmental issues have motived scientists to find new, green and sustainable energy resources such as the wind, solar and biomass energy. Essentially, biomass-derived materials can be utilized in energy storage and conversion devices such as Li-ion batteries, fuel cells, and supercapacitors. Among the biomass resources, lignin is a high volume byproduct from the pulp and paper industry and is currently burned to generate electricity and steam. The …

The Tea Party Versus Planning: A Study Of Tea Party Activism And Its Impact On Local Government Planning, Spencer A. Norman

Theses and Dissertations

The Tea Party movement’s effect on local and regional planning in Virginia has received little study. This work identifies how conservative political activism has impacted planning in the Commonwealth and how planners have responded. The study relies on a qualitative approach involving 22 semi-structured interviews with activists, planners, and citizens, as well as textual analyses of planning documents, local and regional news reports, and Tea Party social media. The resultant findings show that Tea Party activism is rooted in deep seated ideals about private property rights and individualism. It also reveals that planning processes that increased the amount of public …

Wise Choices? The Economics Discourse Of A High School Economics And Personal Finance Course, Tamara L. Sober

Theses and Dissertations

Today’s high school students will face a host of economic problems such as the demise of the social safety net, mounting college student debt, and costly health care plans, as stated in the rationale for financial literacy provided by the Council for Economic Education’s National Standards for Financial Literacy. These problems are compounded by growing income and wealth inequality and the widespread influence of neoliberal ideology. Although one of the major goals of economics education is to teach students to make reasoned economic choices in their public and private lives and provide the skills to solve personal and social …

Effect Of Temperature And Genetic Structure On Adaptive Evolution At A Dynamic Range Edge In The North American Gypsy Moth (Lymantria Dispar L.), Trevor M. Faske

Theses and Dissertations

The study of biological invasions is not only essential to regulate their vast potential for ecological and economical harm, they offer a unique opportunity to study adaptive evolution in the context of recent range expansions into novel environments. The North American invasion of the gypsy moth, Lymantria dispar L., since its introduction in 1869 to Massachusetts, has expanded westward to Minnesota, northward to Canada, and southward to North Carolina. Fluctuating range dynamics at the southern invasive edge are heavily influenced by heat exposure over their optimal (supraoptimal) during the larval stage of development. We coupled genomic sequencing with reciprocal …

Modeling Psychologists’ Openness To Performing Clinical Work With Telepsychology, Bradford S. Pierce

Theses and Dissertations

This cross-sectional study examined whether the Theory of Reasoned Action (TRA) and Technology Acceptance Model (TAM) apply to psychologists’ openness to using telepsychology, and to identify significant personal or environmental predictors of telepsychology adoption. A total of 1,791 licensed psychologists currently practicing psychotherapy in the United States were recruited to complete a previously developed 21-item pool. Personal and environmental characteristics were also collected. Path models representing the TRA, TAM, and a hybrid of both were tested. Also, a logistic regression was used to identify personal and environmental predictors of current use of telepsychology. Results indicated the TRA and TAM were …

Recovery From Design, Cassandra J. Ellison

Theses and Dissertations

Through research, inquiry, and an evaluation of Recovery By Design, a ‘design therapy’ program that serves people with mental illness, substance use disorders, and developmental disabilities, it is my assertion that the practice of design has therapeutic potential and can aid in the process of recovery. To the novice, the practices of conception, shaping form, and praxis have empowering benefit especially when guided by Conditional and Transformation Design methods together with an emphasis on materiality and vernacular form.

Parent-Fostered Enrichment Activities And Academic Outcomes In Middle Childhood, Princess-Melissa T. Washington-Nortey

Theses and Dissertations

Despite numerous educational reforms, elementary school children in the United States continue to lag behind their peers from other developed countries on reading, math and science outcomes. Many interventions focus on strategies aimed at increasing the amount of classroom work children undertake. However, the key to improving outcomes may lie in out of school enrichment activities that facilitate learning. Drawing from Eccles Expectancy-Value theory(Simpkins, Fredricks, & Eccles, 2012), the current study focuses on assessing the impact of parent-fostered enrichment activities on child academic outcomes in the first three years of elementary school. Using secondary data from Early Childhood Longitudinal Study …

Construction Of An Album For Oneself, Maria Tinaut

Theses and Dissertations

Archive and Fiction: Construction of the past and the self is the result of two years of artwork exploring my family archives and my relationship to my family through them. I understand the family as a place of identity in continuous change, serving as a container of history and memory. Conceiving of my family albums as material allows me to approach my family history as a visitor. Mediated memory and constructed memory intertwine in the …

Relocations Of The 'Outraged Slave': Transatlantic Reform Conversations Through Douglass's Periodical Fiction, Nikki D. Fernandes

Theses and Dissertations

Through their editorial arrangements of African-American, Euro-American and European poetry, fiction and news, Frederick Douglass’s anti-slavery periodicals (The North Star and Frederick Douglass’ Paper) imagine a cosmopolitan discourse that predates the segregated realities of the antebellum United States. In spite of Southern blockades against the infiltration of Northern texts, Douglass’s material space uniquely capitalized on the limited restrictions of his reprinting culture to relocate the voice of the ‘outraged slave’ onto a global stage. From the poems of Phillis Wheatley and William Cowper to Charles Dickens’s Bleak House and Douglass’s own novella “The Heroic Slave,” this project considers how …

What's Haunting Jackson Ward? Race, Space, And Environmental Violence, Rachel Spraker

Theses and Dissertations

This research is about examining the way in which racialized environmental violence contributes to exploitative social relations becoming embedded in the everyday world. I argue that the space of the everyday has been produced through cycles of social relations proceeding from and/or tied to racialized environmental violence. I continue the work of critical scholars in asserting that social and environmental violence is linked in the same ideological impulse which seeks to hide itself behind a variety of alienating processes. The slow way in which environmental violence works is particularly impactful in these processes because of its attritional lethality, contributing to …

Open / Close: Assimilating Immersive Spaces In Visual Communication, Anika Sarin

Theses and Dissertations

I am interested in two spaces obverse to each other: open and closed. An open space develops organically based on how people inhabit it. Interacting with an open space is a dynamic, sporadic, multisensory, immersive, and subjective experience. In such spaces, we are confronted with an alternative aesthetic, one that is in conflict with the seamlessness of a closed space. A closed space is anchored on definite variables like structure, use and boundaries. While interaction between people and space is important, the space is tightly controlled and interaction is designed. Through this thesis project, I present a method that metaphorically …

Uncovering The Progress Of Planning For Vulnerability To Sea-Level Rise & Coastal Storms: A Plan Evaluation Of Norfolk, Va & New York City, Eric K. Borchers

Theses and Dissertations

In response to recent storms like Superstorm Sandy and sea-level rise influenced by climate change, cities, particularly those located at the coast, have taken initiative to combat these growing threats with adaptive urban planning. Although civilians residing in susceptible neighborhoods are often the most vulnerable socioeconomically, there has been minimal evidence that planning has accounted for the characteristics of vulnerability. This thesis evaluates the recent planning efforts and vulnerability of Norfolk, VA and New York City to gauge the progress being made toward reducing citizen vulnerability and raising adaptability and preparedness. The most recent peer-reviewed research is consulted to forge …

Leadership Influence On Aviation Safety Culture Inculcation As It Relates To Certified Non-Scheduled Air Taxi Operators, Stephen Birch

Theses and Dissertations

A general aviation industry segment member known as a Certified Non-scheduled Air Taxi Operator (CNATO) conducts passenger flights on-demand for hire. While airline accidents have reached historic lows, CNATO accident rates remain above one per 100,000 hours (NTSB, 2015b). Unlike airlines, the Federal Aviation Administration has not made safety management system implementation mandatory within CNATOs. As a result, there has been no decrease in CNATO organizational accidents over a 6-year period since 2009. Study goals strove to find a predictable method of variable identification influencing at-risk CNATOs. The study utilized a sequential transformative design comprising quantitative surveys and aviation accident …

Misencounters, Francisco J. Besa

Theses and Dissertations

We are immersed in an era of supermodernity, an age defined by excesses: of information—the acceleration of historical time—spatial overabundance—the nullification of distance by electronic media and transportation—and an excess of self-reflexive individuality. In this context, the idea of place is giving way to non-places: designed spaces in which social relations are tangential and the boundary between the individual and the group is increasingly mediated. Media plays an important role in the creation of non-places, by favoring a removed form of communication made pervasive and extensive through mobile devices. The blurring of the line between media and actuality …

Urban Heat Island Demonstration And Temperature Progression Using Oklahoma City, Oklahoma, Elliot Quinn Peltier

Theses and Dissertations

Urban heat islands are urban areas that become large enough to impact local climate, specifically by increasing temperatures. Urban centers are made of surfaces, high concentrations of buildings, and greenhouse gases that are susceptible to retaining heat. As more people move into cities, more space is needed for urbanization, increasing factors that raise temperature. This also affects energy demand, increases need for maintenance, and affects climate sensitive people.

Using the Oklahoma City metropolitan area, the objective is to demonstrate the urban heat island effect to see the extent to which heat islands impact urban climate. The years under observation cover …

Assessment Of Climate Change And Agricultural Land Use Change On Streamflow Input To Devils Lake: A Case Study Of The Mauvais Coulee Sub-Basin, Courtney Jackson

Theses and Dissertations

Since 1993, Devils Lake in North Dakota has experienced a prolonged rise in lake level and flooding of the lake’s neighboring areas within the closed basin system. Understanding the relative contribution of climate change and land use change is needed to explain the historical rise in lake level, and to evaluate the potential impact of anthropogenic climate change upon future lake conditions and management. Four methodologies were considered to examine the relative contribution of climatic and human landscape drivers to streamflow variations: statistical, ecohydrologic, physically-based modeling, and elasticity of streamflow; for this study, ecohydrologic and climate elasticity were selected. Agricultural …

Spatial Optimization Methods And System For Redistricting Problems, Hai Jin

Theses and Dissertations

Redistricting is the process of dividing space into districts or zones while optimizing a set of spatial criteria under certain constraints. Example applications of redistricting include political redistricting, school redistricting, business service planning, and city management, among many others. Redistricting is a mission-critical component in operating governments and businesses alike. In research fields, redistricting (or region building) are also widely used, such as climate zoning, traffic zone analysis, and complex network analysis. However, as a combinatorial optimization problem, redistricting optimization remains one of the most difficult research challenges. There are currently few automated redistricting methods that have the optimization capability …

Circling The Reality Of Public Institutions Anchoring Gentrification: An E-Delphi Study Of Information, Culture, And Community Stakeholders Voicing The Way Forward In Detroit, Michigan, Celeste L. Welch

Theses and Dissertations

Information, culture, and memory centers increasingly anchor urban redevelopment projects in historically marginalized communities challenged with contemporary social and economic disparities. This dissertation situated libraries, archives, and museums within a socio-cultural context and examined the role of cultural heritage institutions in gentrification. Librarians, archivists, curators, and community advocates in Detroit, Michigan shared their viewpoints and experiences of gentrification in a legacy city. Using a modified Delphi process, the e-Delphi panel explored the need for assessing policy, service delivery, and programming in a city of color at-risk to gentrification-induced displacement.

This mixed research study used a concurrent triangulation design. A panel …

“An Uphill Battle”: Psychosocial Health And Self-Care Among Advocates Who Work Against Gender-Based Violence In South Carolina, Ebru Cayir

SC consistently ranked among the highest in the nation in terms of female homicide rates. Non-profit organizations (NPOs) that focus their work specifically on GBV constitute an essential component of prevention and mitigation efforts in SC. Advocates who work for GBV-specific NPOs experience a wide range of psychosocial health and well-being benefits and risks due to their work. This study aimed to: 1) Identify the relationships between engaging in paid GBV-specific advocacy and …

“Bajan To Gullah” Cultural Capital: Wood, Stone, Iron, And Clay 1670 To 1770, Ramona Arlen La Roche

Theses and Dissertations

British planters, merchants and other non-landholding persons from Barbados owned and transported enslaved persons to the South Carolina colonial settlement as early as 1670. However, there is minimal specific information about Africans or Barbadian Creoles selected for these voyages. To date, no empirical research has examined any data on African or African descended artisans (enslaved or free) who accompanied their owners or authorized travelers to the New World. Such historical lack provides negligible if any recognition of the skillsets rendered by specific artisans that significantly enhanced the economic development of both Barbados initially, and later during the early development of …

Narrating The (Im)Migrant Experience: 21st Century African Fiction In The Age Of Globalization, Bernard Ayo Oniwe

Theses and Dissertations

This study examines the fiction of 21st century African writers as a product of engagement with the forces of globalization and the related notions of cosmopolitanism and the fact of South to North migration. Analyzing migrant experiences in the writings of Chris Abani’s Becoming Abigail (2007), Chika Unigwe’s The Black Street Sisters (2009), Chimamanda Ngozi Adichie’s Americanah (2011) and Teju Cole’s Open City (2013), I argue that third-generation African writers, while building on the works of previous generations, take a global turn, and in the process, push the borders of African literature beyond the continent. 21st century African fiction, I …

Well Enough Alone: Stories, Sarah Jane Huskey

Theses and Dissertations

This collection of short stories aims to capture the difficulties of telling anything at all, let alone the truth, the whole story, or the abstract reality. Though its thematic concerns might seem a bit cheerless at first blush, Well Enough Alone aims to treat them as prominent features of day-to-day life rather than gloomy afflictions or the loci of trauma.
