Genetic Diversity Of White-Tailed Deer Populations In Southwestern Pennsylvania And The Development Of A Forensics Panel, Melanie Quain

Electronic Theses and Dissertations

During the 20^thcentury, white-tailed deer (Odocoileus virginianus) became scarce, prompting conservation efforts by hunters and wildlife managers with the goal to recover this species. Various strategies were implemented including reintroductions from areas that still had large deer populations, developing bag limits, seasonal restrictions, and habitat management. These efforts were highly successful across the United States.

Today, white-tailed deer are one of the most abundant and widely-distributed large-bodied mammals in North America. However, there are several important management concerns. In numerous states, including Pennsylvania, CWD negatively impacts deer populations and has become a major health concern. When …

Just Between Us Girls: Discursive Spaces From America's First Gay Magazine To The World's Last Website For Queer Women, 1947-2019, Josie Rush

Electronic Theses and Dissertations

Just Between Us Girls charts the diffusion of queer theory outside of the academy, using convergence theory to examine communication technologies like periodicals and the Web to argue for a conception of queer theory that includes discourse between queer women about queerness. In making this argument, this project creates a lineage of discursive spaces by, for, and about queer women, putting content from these spaces in conversation with canonical queer theorists like Judith Butler, Eve Sedgwick, and Jack Halberstam. Analyzing and contextualizing discursive spaces like Vice Versa (1947-1948), The Ladder (1956-1972), The Furies (1972-1973), AfterEllen, and Autostraddle demonstrates not …

Electronic Theses and Dissertations

This dissertation explores intersections between vulnerability and urban planning in Sub-Saharan Africa, where distinct forms of urbanization are occurring and where there are significant data constraints limiting local studies and urban assessments in the region. The three studies which make up this dissertation offer methodological and theoretical pathways toward examining and measuring the influence of urbanization and planning factors on vulnerability of urban populations in the region. The first study is a literature review and examines existing literature for vulnerability conceptualization in urban environments, the notion of ‘urban vulnerability’, and roles of urban planning and related factors in relation to …

Mapping Rural Literacy Sponsorship Networks : Literacy Infrastructures And Perceptions In Abbyville., Amy Mccleese Nichols

Electronic Theses and Dissertations

Recently, the academy has become aware that rural students are choosing to attend institutions of higher education less often than their urban counterparts. Rationalizing why this particular population remains underserved by institutions of higher learning is a new conversation for higher education. And yet, in literacy studies, the perceived urban/rural divide in terms of national politics sometimes seeps into conversations about the perceived “literacy” or culture of rural peoples. This polarization, unaccompanied by detailed portraits of rural community literacy sponsorship, means that rural areas do not benefit from the consistent attention paid to their urban counterparts in New Literacy Studies. …

Comparing Structure From Motion Photogrammetry And Computer Vision For Low-Cost 3d Cave Mapping: Tipton-Haynes Cave, Tennessee, Clinton Elmore

Electronic Theses and Dissertations

Natural caves represent one of the most difficult environments to map with modern 3D technologies. In this study I tested two relatively new methods for 3D mapping in Tipton-Haynes Cave near Johnson City, Tennessee: Structure from Motion Photogrammetry and Computer Vision using Tango, an RGB-D (Red Green Blue and Depth) technology. Many different aspects of these two methods were analyzed with respect to the needs of average cave explorers. Major considerations were cost, time, accuracy, durability, simplicity, lighting setup, and drift. The 3D maps were compared to a conventional cave map drafted with measurements from a modern digital survey instrument …

The Effects Of Urbanization On Avian Seed Dispersal Success Of Toxicodendron Radicans (Anacardiaceae), Aiden M. Stanley

Electronic Theses and Dissertations

Urbanization is increasing at a dramatic rate as the human population increases. While it is well-known that urbanization tends to decrease species diversity (i.e., biotic homogenization), it is not known how urbanization affects the frequency and efficiency of species interactions. Seed dispersal is a plant-animal interaction that depends on disperser feeding rate, disperser diversity, probability of seed dispersal and germination. How these factors are affected by urbanization however is unknown. In this study, we evaluate how urbanization alters these factors. Urban sites had 2x higher feeding rate and 3x higher number of disperser species. The probability of seed dispersal however …

Automation Of State Climate Office Processes & Products: Developing Efficient Approaches For Data Dissemination, Michael Shoop

The Ethics Of Occultic Communication: An Invocation Of Joshua Gunn And Sissela Bok, James Thomas Begley Jr.

Electronic Theses and Dissertations

Occultic rhetoric, according to Joshua Gunn, is a genre of discourse concerned with the study and practice of secret communications. The strategic sharing of secret messages involves a host of methods and conventions designed for the selective disclosure of hidden knowledge, thus controlling the boundaries of (and accessibility to power between) insider and outsider groups. Occultic rhetoric has its uses in everyday encounters, but the abuse of such manipulative strategies, especially by those in the academy and other positions of power and trust, calls for an ethical response. This dissertation submits occultic rhetoric to moral investigation by incorporating the works …

The Influence Of Question Sequencing Using Formative Assessment In Introductory Statistics, Bryan Nelson

Electronic Theses and Dissertations

Formative assessment has long been used to gauge students’ understanding of course material prior to taking an exam. With the advent of more advanced technology, only recently have instructors been able to combine formative assessment with a student response system to allow students to respond to questions in real time during class. Previous studies show mixed findings on the relationship between the use of student response systems and student learning. For example, some studies show that those students who used a student response system performed better on exams or in the course when compared to those who did not, while …

As awareness of this issue in both Texas and the United States increases, efforts to educate communities, advocate for new policies, and provide services to survivors are on the rise. One strategy utilized by organizations, agencies, and individuals across Texas serving survivors of human trafficking is the use of coalitions. Limited research addresses coalition sustainability within the context of issues outside healthcare initiatives facing communities, including human trafficking. Due to the limited research surrounding community …

Anthropogenic Landscapes Of Amazonia : A Spatial Analysis Of Landscape Modification And Settlement Organization At Macurany, Brazil., M. Grace Ellis

Electronic Theses and Dissertations

Anthropogenic landscapes are the product of complex human-environment processes that form distinct features in the landscape, which materially preserve and reflect human behavior. Anthropogenic landscapes in Amazonia likely date back to human colonization of the region around 16,000 BP. Since colonization, humans have been marking, modifying, managing, and engineering the landscape resulting in a mosaic of anthropogenic landscape features across Amazonia. The diversity of ancient landscapes documented in Amazonia reflects the cultural heterogeneity that existed in the past. This research explores the complex human-environmental processes that form distinct, identifiable, lasting features on the landscape and what these features can illuminate …

The Suburban Nightmare: A Study Of Atmosphere, Mood And Emotion, Ericka Sobrack

Electronic Theses and Dissertations

In this thesis body of work, I focus on the implied human presence through the lack of actual human figures. I believe there is more to say in a landscape with the absence of the figure, allowing the dialogue to be read and interpreted by a larger audience. I am particularly satisfied with White Knuckles, shown in figure 3, because I collide reason with imagination, thus contradicting the context and interpretation of the subject matter. In White Knuckles, I deal with formal elements such as composition, atmosphere, lightness and darkness as well as nuances of color. I have also considered …

From The Temple To The Synagogue: Exploring Changes In Judaism After The Fall Of The Second Temple, Adam Cohen

Electronic Theses and Dissertations

"From the Temple to the Synagogue" is an analysis on the influence of external cultures, predominantly the Persian religion of Zoroastrianism on the early rabbis following their failed revolt against Rome and the destruction of the Second Temple in the first century CE. How did the Jewish people react to the upheaval of their center of worship? What can we attribute to the major changes in their religious literature and centers of worship following the demise of their rebellion? Is it possible that what has traditionally been seen as an isolated and uniform group of people did in fact borrow …

Pine, Aphids, And Parasitoid Wasps: Patterns Of Cospeciation And Host Switches In A Tri-Trophic System, Amber Bass

Electronic Theses and Dissertations

Ecological interactions may drive speciation events, and the processes that drive these speciation events can leave behind patterns in the phylogenies of interacting taxa. These patterns have been studied extensively in herbivores and host plants, as well as parasites and their hosts, but rarely in tri-trophic systems. Here, we examine three closely related groups of interacting taxa, including parasitoid wasps (Pauesia), aphid herbivores (Cinara), and pine trees (Pinus) to determine if the patterns between each interacting taxa indicate that cospeciation or host switches are more dominant. We create phylogenies of Cinara and Pauesia in the southeastern United States using ddRADseq …

Handgun Carrying Patterns And Suicide Risk Among Youth., Teresa Jane Mcgeeney

Electronic Theses and Dissertations

Recent data have shown marked increases in carrying of handguns among youth. Though firearms are often discussed using a lens of prevention of violence towards others, the majority of firearm deaths are suicides. Youth suicide has also seen steady increases across the United States in the past decade, demanding urgent solutions to curb this concerning trend. Klonsky and May’s Three Step Theory (3ST) outlines three primary steps that lead to death by suicide and proposes that access to and familiarity with lethal means, such as firearms, make up a critical component of the etiology of suicide. With youth suicide and …

Exploring Place As A Producer Of Localized Art Styles And Its Role In A Contemporary Global Art World., Alexis Doerr

Electronic Theses and Dissertations

Place as influencing the production of local art idioms is examined. Pierre Bourdieu’s theory of habitus and Michael Baxandall’s concept of visual capacity explain the social, economic, and physical structures that comprise place and affect how people perceive and evaluate the world around them. Art education, professional development opportunities, and local arts spending are discussed as the main structures of place that shape local art idioms and art making processes. South Dakota artists Harvey Dunn, Terry Redlin, and Dorothy Morgan are used as a case study. The writer argues that due to globalization the long-standing structure of art center and …

A Multi-Plot Assessment Of Vegetation Structure Using A Micro-Unmanned Aerial System (Uas) In A Semi-Arid Savanna Environment., Nicholas E Kolarik

Electronic Theses and Dissertations

Unmanned Aerial Systems (UAS) have emerged as a capable platform for measuring vegetation health, structure and productivity. Products derived from UAS imagery typically have much finer spatial resolutions than traditional satellite or aircraft imagery, allowing the spectral and structural heterogeneity of vegetation to be mapped and monitored with more detail. This study uses UAS-captured imagery from the Chobe Enclave of northern Botswana. Flights were conducted across a gradient of savanna sites classified as grass-, shrub-, or tree-dominated. We compare multiple approaches for extracting woody vegetation structure from UAS imagery and assess correlations between in situ field measurements and UAS estimates. …

Investigating A Mental Health Literacy Intervention Among Economically Disadvantaged Youth, Jayna Mumbauer

Electronic Theses and Dissertations

Mental health is a critical and pervasive issue for children and adolescents in the United States, with one in five youth living with a diagnosable mental health condition (Center for Disease Control and Prevention, 2017). Despite the increasing rates of mental health disorders, barriers to treatment are abundant and most young people do not receive appropriate treatment (Merikangas, 2009). Mental health literacy is the knowledge and beliefs surrounding mental health that guide recognition, management, and prevention (Jorm, 1997, p. 143). Mental health literacy is a particularly important framework for youth from economically disadvantaged backgrounds as they face increased vulnerabilities to …

Electronic Theses and Dissertations

Confronted with negative consequences of rural youth outmigration, many rural communities are interested in how to recruit and retain young adults. Yet, attention has largely been focused on those who leave. This study thus explores the experiences of young adults who make conscious commitments to improving the communities of Appalachian Kentucky despite many obstacles and pressures to leave. Two aims were established in this pursuit: 1) Understand and provide deep description of young adults’ experience of committing to stay and work in Appalachian Kentucky and the meaning they make of these decisions and 2) Develop a context specific framework for …

Moving Towards A Dialogic Pedagogy: Using Video Feedback As A Teaching Tool To Respond To Writing Across Disciplines, Paul Martin

Electronic Theses and Dissertations

This study examined the impact of video feedback (VF) as a teaching tool for responding to writing activities and assignments across disciplines and whether or not VF can help instructors facilitate dialogic exchanges between students and teachers. I conducted three case studies with three different instructors from three different disciplines: psychology, history, and nanoscience. To determine the potential of video feedback to facilitate dialogic pedagogies, this dissertation examined the presence of transformational leadership theory (Parkin, 2017), the voices of teaching and learning (Collison et al., 2001), and gesture theory (Bavelas et al., 2014; Peräkylä & Ruusuvuori, 2008) for the paralinguistic …

A Systematic Assessment Of Socio-Economic Impacts Of Prolonged Episodic Volcano Crises, Justin Peers

Electronic Theses and Dissertations

Uncertainty surrounding volcanic activity can lead to socio-economic crises with or without an eruption as demonstrated by the post-1978 response to unrest of Long Valley Caldera (LVC), CA. Extensive research in physical sciences provides a foundation on which to assess direct impacts of hazards, but fewer resources have been dedicated towards understanding human responses to volcanic risk. To evaluate natural hazard risk issues at LVC, a multi-hazard, mail-based, household survey was conducted to compare perceptions of volcanic, seismic, and wildfire hazards. Impacts of volcanic activity on housing prices and businesses were examined at the county-level for three volcanoes with a …

Ecometric Estimation Of Present And Past Climate Of North America Using Crown Heights Of Rodents And Lagomorphs: With Application To The Middle Miocene Climatic Optimum, Julia Schap

Electronic Theses and Dissertations

Continental scale studies on ungulate crown heights in relation to climate and habitat changes have revealed a correlation between increasing hypsodonty and a shift to more arid environments. Small mammals have been shown to adapt to changing habitats millions of years earlier than larger mammals. In this study I examined fossil localities throughout the last 37 Ma across North America. Diversity of rodents and lagomorphs were analyzed through this time period, with examination of community structure characterized by relative percentages of taxa with different crown heights. Overall, a decrease in precipitation and temperature was found across North America from 37 …
