Electronic Theses and Dissertations

Preliminary investigation of the Bullard Peak metamorphic series (BPMS) in the northwestern Wind Mountain quadrangle within the Burro Mountains of southwestern New Mexico suggests a possible previously unidentified shear zone, prompting detailed (1:12,000) geologic mapping and collection of structural data. The study area has a complex tectonic history, including 1) ~1.65 Ga metamorphism during accretion of the Mazatzal terrane to Laurentia’s southern margin; 2) ~1.4 Ga intrusion of Granite and Rhyolite Province granitoids; 3) significant uplift during the formation of the Ancestral Rockies (~300 Ma) and the Rocky Mountains (~70-50 Ma); and 4) inversion tectonics with reactivation of compressional faults …

Evaluation Of Genetic Diversity And Stability Of Colocasia Cultivars Using Issr, Seukmin Hong

Electronic Theses and Dissertations

Using 44 ornamental Colocasia cultivars planted at Stephen F. Austin State University (Nacogdoches, TX), cultivar assessment, genetic diversity, stability, and relationship were examined with banding patterns produced from Inter-simple sequence repeat (ISSR) markers. Comparing banding patterns of vegetatively propagated clones of each cultivar, genetic stability was examined. Unweighted pair group method with arithmetic mean (UPGMA) and principal coordinate analysis (PCO) were performed to examine genetic relationship that can explain a need for the new classification Colocasia gigantea and recent movement of re-classifying Colocasia antiquorum. Average Shannon’s diversity index for all loci was found to quantify genetic diversity. The genetic …

Estimating Density And Residency Of Bottlenose Dolphins (Tursiops Truncatus) In Three Estuarine Sites In South Carolina, Jessica Nicole Conway

Electronic Theses and Dissertations

Of the three estuarine bottlenose dolphin stocks in South Carolina, two are considered data insufficient, with no minimum population estimate or assigned potential biological removal value. Additionally, the Northern Georgia Southern South Carolina Estuarine System (NGSSCES) stock’s boundaries are based on sighting data that do not extend to the full area encompassed by the boundary lines. In areas where stock boundaries are not clearly defined and data is insufficient for traditional methods of estimating abundance, density may provide insight into local distributions and serve as a proxy for actual abundance. Photo-identification surveys were conducted in three sites, representative of the …

Habitat Use Of Blacktip Sharks (Carcharhinus Limbatus) At Fishing Piers, Kelsey L. Spencer

Electronic Theses and Dissertations

Blacktip sharks (Carcharhinus limbatus) can be observed near fishing piers throughout the summer along the northeast coast of South Carolina. These piers attract and support a wide variety of potential prey and sharks are able to forage on fishers’ discards with minimal energetic cost. I tagged 12 blacktip sharks with acoustic transmitters, monitored piers with acoustic receivers, and conducted pier-creel surveys to determine the habitat use of blacktip sharks at fishing piers, factors that influenced residence time and presence/absence at piers, and any cyclical patterns in visits to piers. Data were analyzed with pier association indices (PAI), mixed models, and …

Geological Framework Of The Continental Shelf Of South Carolina Winyah Bay: Paleodrainage, Transgressions And Essential Fish Habitat, Amanda Roach

Electronic Theses and Dissertations

A regional geophysical survey of the inner continental shelf off central South Carolina was completed on a cooperative cruise between NOAA and Coastal Carolina University in July 2015. An integrated mapping suite comprised of subbottom echosounder, side scan, multibeam and split beam sonars was used to define the regional geologic framework, including paleodrainage patterns across the shelf and to identify potential fish habitat locations that will provide additional inputs to a thematic habitat mapping routine developed by NOAA. Results from the thematic mapper characterization suggest that large-scale framework elements such as paleochannel networks may play a role in determining benthic …

The Art Of Silence., Lydia Anne Kowalski

Electronic Theses and Dissertations

This dissertation argues that the role of silence as essential to experience the full aesthetic beauty of art in a museum setting. Museums have changed their focus due to socio-economic and financial pressures. They have changed from silent “temples” for art conservation and exhibition to places for interactive art education, entertainment, and social gathering. The results of these changes have been both positive and negative. Attendance has increased, enhancing the museum experience, engaging more diverse audiences in museum activities, and dispelling the “elitist” image of the museum. These changes, however, have resulted in the loss of a silent space to …

This Is Just A Phase : The Impact Of Population Structure On Haplotype Phasing And Linkage Disequilibrium Measures At Functional Genetic Sites., Roxanne Kaaren Leiter

Electronic Theses and Dissertations

The block-like structure of the human genome has been the subject of many scientific papers and is of practical significance in large-scale genome-wide association studies. How stringent haplotype block boundaries are within and between populations has been the subject of ongoing debate within human population genetics. This thesis will contribute to the description of universal and population-specific haplotype blocks at functional sites, namely across the IL-10 gene family (including IL-10, IL-19, IL-20 and IL-24), which is involved in a number of immune system processes, and MAPKAP-K2, an adjacent and functionally significant kinase gene. Beyond the description of blocks across these …

Electronic Theses and Dissertations

Seeking to understand the media’s influence over society, and the way the media motivate us to conform to specific ideals, this thesis focuses on how female bodies in particular are consistently idealized and objectified in mainstream media. Through television, print, and the internet, the media serve as our world’s main means of mass communication. Noting this, this text seeks to understand the female body’s historical objectification through art history and genres of the nude, how this has transferred to contemporary media, and finally states that these stereotypes and norms can be challenged through the work of contemporary artists. By reclaiming …

The Role Of Kinases And Phosphatases In The Pathobiology Of Porphyromonas Gingivalis., Sarah Whitmore

Electronic Theses and Dissertations

Periodontal diseases result from the interplay between the dysregulation of the host inflammatory response and the actions of a dysbiotic bacterial community. These chronic inflammatory conditions affect persons on a worldwide scale. P. gingivalis is strongly implicated as a key periodontal pathogen in the more severe manifestations of periodontal diseases such as periodontitis. A core element of P. gingivalis pathogenicity is its dysregulation of innate immunity, including suppression of IL-8 production by gingival epithelial cells. The NF-κB family of related transcription factors plays a central role in regulating many important aspects of innate immune responses. NF-κB RelA/p65 homodimers regulate transcription …

Since The Time Of Eve : La Leche League And Communities Of Mothers Throughout History., Joanna Paxton Federico

Electronic Theses and Dissertations

La Leche League International (LLL) is the oldest and largest breastfeeding support group in the world. This thesis examines how, beginning in 1956, seven Catholic housewives from suburban Chicago built up the institutional knowledge to sustain a cohesive global network of breastfeeding mothers. It also explores how LLL managed this knowledge over time in response to developments in scholarship and changing social conditions. Based on a narrative analysis of LLL publications, this thesis argues that the League’s founders drew selectively from existing bodies of knowledge and from their own cultural perspectives to establish a sense of community among breastfeeding women. …

The Feelings We Harbor - The Role Of Collage In Arousing Powerful Emotions In An Esl Classroom., Irina V. Mcgrath

Electronic Theses and Dissertations

Traditional literacy education in the U.S. relies exclusively on language-based models. This can be particularly challenging for English language learners, who often find themselves bound by the constraints of the English language and limited in their expressions of thought and emotion. Current research on English language teaching, largely targeted towards native English-speaking students, suggests that incorporating various alternate modes of communication and representation improves literacy learning. Studies that address English language learning for non-native speakers are sparse. The purpose of this arts-based, qualitative, descriptive study is to fill this gap in the literature. Using collage making as a communicative mode, …

Control Of Power Electronic Interfaces In Distributed Generation., Mohammad Mohebbi

Electronic Theses and Dissertations

Renewable energy has gained popularity as an alternative resource for electric power generation. As such, Distributed Generation (DG) is expected to open new horizons to electric power generation. Most renewable energy sources cannot be connected to the load directly. Integration of the renewable energy sources with the load has brought new challenges in terms of the system’s stability, voltage regulation and power quality issues. For example, the output power, voltage and frequency of an example wind turbine depend on the wind speed, which fluctuate over time and cannot be forecasted accurately. At the same time, the nonlinearity of residential electrical …

Factors Associated With Federal Student Loan Default Among Borrowers In A Statewide System Of Community And Technical Colleges., Brittany Inge

Electronic Theses and Dissertations

Community colleges serve as a gateway to higher education for millions of American college students. Open-door admission policies and federal student aid facilitate the access that two-year public institutions provide, particularly for students who are under-resourced or academically under-prepared for college. However, a substantial number of community college students who use federal student loans to pay for college ultimately fail to repay the loans, yielding negative consequences for borrowers, institutions, and taxpayers.

By employing a Hierarchical Generalized Linear Model (HGLM) this study investigates individual-level and institution-level factors associated with federal student loan default among borrowers who attended a two-year public …

Low ppb and even sub-ppb level of detection for some VOCs was achieved during the analysis …

Pcb-Associated Steatohepatitis And The Role Of Nuclear Receptors., Heather Brooke Clair

Electronic Theses and Dissertations

Metabolic diseases, including fatty liver disease, hyperglycemia, and obesity, result when body systems responsible for managing allostasis (dynamic homeostasis across systems) are pressured beyond their collective compensatory reserve. Nutritional excess contributes to this state, the capacity of which is limited by genetic variation, and failure of one system will gradually lead to pathological overload in the others. Agents which act directly on the communication machinery linking these connected systems can also change the point at which allostatic load becomes allostatic overload. Environmental exposure to polychlorinated biphenyls (PCBs), a class of persistent organic pollutant, is associated with a specific form of …

Educating Critically : Challenging The Familiar Contours Of Literacy Teacher Education., Bianca Nightengale-Lee

Electronic Theses and Dissertations

The shifting cultural ecologies of U.S. classrooms emphasize acknowledging difference, accepting diversity, and sustaining both cultural and linguistic plurality (Banks & Banks, 2009; hooks, 1994; Paris 2014). Teacher education programs play an integral role in preparing Pre-Service Teachers (PSTs) with skills, knowledge, and dispositions necessitated by a growing Culturally and Linguistically Diverse (CLD) student population (Cruz, Ellerbrock, Vasquez & Howes, 2014). To enact equitable teaching practices reflective of 21st century students, PSTs need to demonstrate a level of cultural awareness that acknowledges the racially, socially, and politically charged societal structures that shape education for CLD students (Hall & Carlson, 2016). …

Numerical Investigation Of Drop Impingement On Dry And Wet Surfaces., Yisen Guo

Electronic Theses and Dissertations

In-flight icing due to supercooled large droplets (SLDs) imposes great danger on aviation safety. Because of the large size, SLDs have different characteristics than typical cloud droplets that most icing encounters involve. As a result, SLDs more likely hit the wing surface and move into areas not protected by de-icing devices to form ice, which can lead to loss of lift, increase in drag, altered controllability, and eventually stall and loss of control of the aircraft. The phenomenon of droplet splashing is considered as the most important aspect of the SLD icing accretion problem. Although previous studies have established splashing …

Norton Commons, Clifton, And Social Equity : A Neighborhood, Inter-Neighborhood, And Regional Comparison Of New Urbanism And “Old” Urbanism., Aaron J. Stephenson

Electronic Theses and Dissertations

This dissertation examines two paradigms aimed at restoring urban vitality-- grassroots neighborhood revitalization and New Urbanism. New Urbanism is comprised of progressive goals, but unfortunately the relevant literature suggests that these goals have not been achieved. As such, this study focuses upon the degree to which each of these paradigms, New Urbanism and grassroots revitalization, may impact social equity on a spatial level. This dissertation explores this through a comprehensive micro-level comparison of two neighborhoods in Louisville, Kentucky- Clifton and Norton Commons. Clifton is an activist urban neighborhood that has been revitalized in recent decades, to become one of Louisville’s …

Lgbtq+ Nondiscrimination Laws In Kentucky., Christopher M Wales

Electronic Theses and Dissertations

This thesis explores the political and demographic obstacles facing the Fairness movement in Kentucky in regards to local employment protection ordinances for LGBTQ+ persons (Fairness Ordinances). Using case studies on recent Fairness debates in Berea and Bowling Green, this thesis explores the concern some Kentuckians have about LGBTQ+ nondiscrimination ordinances in their communities. From these cases studies, it can be concluded that many of the concerns espoused by opponents of Fairness are simple scare tactics with no evidence supporting their claims. This thesis then utilizes a logistical regression to uncover what demographic characteristics increase the odds of a municipality possessing …

Economic Growth Or Economic Development? An Examination Of Local Government Objectives Through Citizen Well-Being Framework., Mohd Mobin Khan

Electronic Theses and Dissertations

Economic development is considered one of the key functions and responsibilities of Federal, State, and local governments in the United States. However, most of the policies and strategies related to economic development, regardless of their focus or funding, have a strong role of municipalities for their implementation. Within local governments, economic development efforts often seem to not truly focus on the aspects of ‘development,’ but can rather be characterized as focused on economic ‘growth’ and measured in terms of economic activity generated. Job creation and the enhancement of tax base or revenue are considered two of the most important goals …
