The portable electronics industry has developed exponentially, especially over the last couple of decades and therefore the importance of efficient electrochemical energy storage systems cannot be overstated. Li-ion batteries have been the predominant rechargeable energy in use, however, they have their own particular drawbacks viz. flammability of the electrolyte, expensive mining of the Li metal etc. This is where the importance of Na-ion batteries lie. This research focuses on using existing transition metal oxides (TMOs) and tuning their crystal …

This Is A Black-White Conversation : Navigating Race, Class, And Gender At An Urban School., Jelisa S. Clark

Electronic Theses and Dissertations

This research examines how racial ideologies operate and shape experiences in an urban school. Using ethnographic methods, consisting of observations, formal and informal interviews, document analysis, I pose the following questions: (1) To what extent is OS premised on the Black male crisis discourse; (2) How do the students, faculty, and staff navigate the boundaries of race, class, and gender; and (3) How do racial ideologies (i.e., colorblind racism and Black male crisis discourse) influence the experiences of faculty and students? Findings suggest that colorblind ideology operates on various facets and on multiple levels in the school. By focusing on …

Vehicle Make And Model Recognition For Intelligent Transportation Monitoring And Surveillance., Faezeh Tafazzoli

Electronic Theses and Dissertations

Vehicle Make and Model Recognition (VMMR) has evolved into a significant subject of study due to its importance in numerous Intelligent Transportation Systems (ITS), such as autonomous navigation, traffic analysis, traffic surveillance and security systems.

It begins with a historical overview of the revolution and an explanation of how the media have framed other refugee groups and influenced American public opinion by doing so. Then the thesis explains how 713 news articles, coded for attributes and value frames, described Hungarian refugees from November 1956 until December 1957. American news media framed Hungarian refugees in a positive way, which matched the positive American public opinion of this particular refugee group. The thesis is divided into five chapters. Chapter one introduces …

Oil, Space, And National Imaginaries : Discursive Productions By Standard Oil New Jersey Post Wwii., Michael Poindexter

Electronic Theses and Dissertations

In a moment of self-representation, Standard Oil New Jersey commissioned a large photo ‘documentary’ project of nearly 80,000 images taken between the years 1943 to 1950. Produced for publication and exhibition, images captured “how oil seeped into every joint” of America, and displayed a specific landscape for post WWII economies. While a stable and centralized industry was ever more tied to the state’s idea of national security, Standard Oil needed a public relations project to address social concerns of big oil. This singular perspective on oil space is problematic. Community histories and social relations are seen through Standard Oil’s own …

Remotely Sensed Heat : Variation And Change In Surface Urban Heat Islands In A Temperate Eco-Region Of The United States., Jeremy Sandifer

Electronic Theses and Dissertations

Urban heat island (UHI) is a term used to describe increased surface and atmospheric temperatures in an urban core relative to surrounding non-urbanized areas. To examine the variability introduced into derived estimates of the surface UHI, this study constructs and compares multiple remotely sensed indicators of the surface UHI for major metropolitan cities of a temperate eco-region of the United States. The Moderate Resolution Imaging Spectroradiometer (MODIS) 8-day, 500-meter product (MOD11A2) is the source data used to calculate six different RS-derived UHI indicators for the year 2002 to 2012. The different SUHI indicators are evaluated using the Spearmans Rho rank-order …

Breaking The Cycle Of Silence : The Significance Of Anya Seton's Historical Fiction., Lindsey Marie Okoroafo (Jesnek)

Electronic Theses and Dissertations

This dissertation examines the feminist significance of Anya Seton’s historical novels, My Theodosia (1941), Katherine (1954), and The Winthrop Woman (1958). The two main goals of this project are to 1.) identify and explain the reasons why Seton’s historical novels have not received the scholarly attention they are due, and 2.) to call attention to the ways in which My Theodosia, Katherine, and The Winthrop Woman offer important feminist interventions to patriarchal social order. Ultimately, I argue that My Theodosia, Katherine, and The Winthrop Woman deserve more scholarly attention because they are significant contributions to women’s …

Analysis Of Gender And Gender-Related Implicit Leadership Themes In Hr Practitioner Literature : A Comparison Of The United States And Brazilian Hr Practitioner Publications., Flavia De Sousa E Castro Rossetti

Electronic Theses and Dissertations

Among the many factors studied in relation to the women and leadership equality gap are gender stereotypes, implicit leadership theories, and the congruity of gender role expectations (Eagly, & Karau, 2002). Multiple studies in the scholarly literature support the finding that men, rather than women, are more likely to be seen as leaders (Bierma, 2016; Eagly, & Schmidt, 2001), and this finding appears to be robust across some cultures (Schein, 2001). While the scholarly research on women and leadership has been burgeoning, few research studies have investigated how human resource (HR) practitioner literature addresses themes related to women and leadership …

An Analysis Of The Relationship Between Snowpack And Groundwater Across Utah Watersheds., Samuel Wright

Data was gathered on SWE from seventeen SNOTEL sites and groundwater elevation data was gathered from six continuously monitored groundwater wells. This data was gathered for January through May for 2011, 2013, and 2014 in order to represent the water conditions that were above average, below average, and average respectively. Using MLR formulas the total SWE for each sub-watershed was determined for each year/month. Afterwards a correlation analysis was performed to determine if any association existed between SWE …

Colorectal Cancer Fit Screening In The Hope Vi Population Of Jefferson County, Kentucky., Jeffrey D. Stone

Electronic Theses and Dissertations

Using pre-post survey data collected from 209 randomly selected African American people from the population of former residents of Clarksdale and Sheppard Square public housing areas, this study explores the relationship between individual characteristics and colorectal cancer screening behavior, measured by the uptake of the Fecal Immunochemical Test (FIT) and by prior colorectal screening, while controlling for neighborhood factors and geographic proximity to healthcare facilities. This particular public housing population is of interest because of their relocation from the downtown area, where healthcare facilities are within walking distances, to other public housing units either in large apartment complexes or scattered …

Dead Places : American Horror, Placelessness, And Globalization., Katherine Ashley Wagner

Electronic Theses and Dissertations

This dissertation investigates particular American anxieties concerning cultural identity and place, particularly fears about America’s place (or lack thereof) within the global world, that can be seen throughout much of post-WWII American horror literature and film. More specifically, this project explores how an existent pattern of visual and narrative depictions of destroyed bodies and places illustrates larger tensions and fears about placelessness—the affect and effect of incomplete, partial, or inauthentic relationships with the places that provide cultural and individual identity and meaning. I argue that representations of placelessness within American horror texts become vehicles for addressing and signifying American fears …

Transversal Approaches And Ecological Artwork., Madison Deanna Sevilla

Electronic Theses and Dissertations

This work explores systematic ecology as it relates to sculpture and language. This project exists in two parts: a written thesis and a thesis exhibition. Although both works explore ecological systems, Unseen: Visualizing Ecological Systems investigates visualizations and concepts of the ecological, whereas this thesis continues the exploration into the ramifications of disruptions in systems. Ecological systems such as the environmental, social/mental, economic, and political define the foundations of our known world and encapsulate all regions of society. No single system can function independently of the rest and all systems contain some aspect of human-system involvement. By using the work …

American Emergency : Catastrophe And Culture In The U.S.A., From The Civil War To Hurricane Katrina., Lynda Kristian Mercer

Electronic Theses and Dissertations

This dissertation examines socio-cultural experiences of national disasters in the United States as they intersect with political rhetorics of democracy, to understand the forms and functions of state power as it is mediated through famous historical figures. Tracing the manifold possibilities from within and around the disruptive spacetimes of disaster, which sociologist Harvey Molotch describes in their ultimate function as societal “rationalizers” (371), I analyze catastrophes as contested spaces and histories that often get situated as variations on the “man vs. nature/god/man” binaries in public discourse. By analyzing the deployment of, and response to, such explanatory frameworks in the United …

Electronic Theses and Dissertations

This study analyzes recent findings analyzing coffee shops as alternative indicators of gentrification and the spatial relationship to violent crime. This thesis seeks to add to this literature by providing additional alternative gentrification indicators such as breweries, distilleries and wineries. The change in number of coffee shops, breweries, distilleries and wineries may impact crime rates and multiyear average incidences of homicide and robbery in the city of Louisville, KY. The first hypothesis states that gentrification decreases multiyear average robberies per census tract from 2010 to 2016. The second hypothesis states that gentrification decreases multiyear average homicides per census tract from …

Governing The Urban Water Commons : Essays On Collaborative Policy Networks In A Polycentric Ecology Of Urban Water Policy Games., Emmanuel Frimpong Boamah

Electronic Theses and Dissertations

Governing social-ecological systems, such as the urban water commons, is a multi-scale and multi-sector (polycentric) human-environment process. This dissertation interrogates this process by situating itself within the Ecology of Games Framework by Norton Long (and updated by Mark Lubell) and the literature on polycentric governance by the Bloomington School of Political Economy. The dissertation’s three essays 1) offer both theoretical and methodological means to enact polycentric public economies within the ecology of games framework, and 2) explicate the conditions under which interoganizational collaboration is fostered within a polycentric ecology of policy games in governing the Middle Rio Grande urban watershed. …

Urban Governance Reconsidered : Assessing The Roles Of Public-, Private-, And Third Sector Leaders In Governing The Modern City., Benjamin Colby Leamon

Electronic Theses and Dissertations

As central cities redefine themselves after decades of commercial abandonment, “urban renaissance” movements, white flight, and the gentrification of their central urban neighborhoods, are cities still governed by the political-business coalitions conceptualized by urban regime theorists, or have new players emerged? Further, as cities continue to evolve within the post-Fordist landscape, do extant theories of urban governance, themselves built upon decades-old observations, continue to provide adequate models for urban governance as it actually exists in cities today? This dissertation is a quantitative and qualitative examination of contemporary urban governance in the United States, and the roles of CDCs and anchor …

Niche Modeling For The Giant Panda, Ailuropoda Melanoleuca, And The Original Panda, Ailurus Fulgens: Habitat Preferences And Evolutionary Consequences, Lauren M. Lyon

Electronic Theses and Dissertations

The well-known symbol for conservation, the giant panda bear, and the original red panda have been forced into remote habitats due to anthropogenic disturbance, making ecological study difficult. Therefore the first known species distribution model was created to predict the most likely areas of occurrence within the known range of these elusive animals. These models were then projected onto North America and evaluated against existing breeding programs. Additionally, the close proximity of the Gray Fossil Site and the discovery of the most complete fossil red panda specimens in the world allowed ecomorphological comparisons between the modern red panda, Ailurus fulgens …

English Proficiency Associated With The High School Grades Of Lep Students In Abilene Isd, Donald A. Dolton

Electronic Theses and Dissertations

In recent years, immigration into the U.S. has increased because of growing economic problems around the world. Economic globalization and technological developments (internet access and the ability to move massive amounts of information and people in a short amount of time) have influenced the number of those seeking asylum. Accordingly, the U.S. school system continues to see an increase in students who are culturally diverse with greater educational deficiencies and limited English proficiency (LEP). In Texas there has been a 90% increase in the number of immigrants from 1990 to 2010 (National CE). This means that currently immigrants make up …

The Modern Church Communicates: Rhetoric And Hypertext In Church Website Design, Edward Palmer

Electronic Theses and Dissertations

The Internet and the World Wide Web have supplanted many paper-based information systems. People turn to the web to locate local services in the same way they find ecommerce sites such as Amazon. Churches of all sizes must develop effective and attractive websites to attract new members and inform existing members. These two groups form distinct audiences that must be correctly targeted by the website content. Other churches may visit to gather ideas for their programs; they are a third group of site visitors. Organization of hypertext on the web requires skills that are different than writing for print. Technical …

Advancing Sylvia Wynter's Reimagination Of The Human And Counter-Poetics: A Critique Of Contemporary Western Science Discourse In Cosmos—A Spacetime Odyssey, With Host Neil Degrasse Tyson, Claire E. Slattery-Quintanilla

Electronic Theses and Dissertations

This thesis investigates the entanglements of "modernity/coloniality," Western conceptualizations of time and space, and questions of the "human" as they are situated in contemporary Western science discourse and thought. Through a textual analysis of the 2014 science television documentary series Cosmos: A Spacetime Odyssey presented by famous black astrophysicist Neil deGrasse Tyson, I argue Tyson refuses to discuss race as it relates to Western science on three levels in Cosmos: the racialized logic inherent in Western science, the sociohistorical relationship between European colonial racial subjugation and the emergence of contemporary Western science, and Tyson's experience as a black man …

Factor Invariance Of The Standard Achievement Admission Test By Gender And School Types, Mohammed Alqabbaa

Electronic Theses and Dissertations

This study examined the factorial structure of the SAAT with exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). Specifically, a CFA of a four-factor model (the hypothesized model) was tested to see if the model had good fit as well as a model generated from an EFA. The EFA showed that the SAAT test only measured two factors (biology and chemistry), not the four posited by the test developers. The CFA provided good fit to a two-factor model; however, a CFA showed that the hypothesized four-factor model also fit the data well and so the hypothesized model was selected …
