Use Of Unoccupied Aerial Vehicle (Drones) Based Remote Sensing To Model Platform Topography And Identify Human-Made Earthen Barriers In Salt Marshes, Joshua J. Ward
Masters Theses
Elevation is a foundational driver of salt marsh morphology. Elevation governs inundation and hydrological patterns, vegetation distribution, and soil health. Anthropogenic impacts at grand scales (e.g., rising sea levels) and local scales (e.g., infrastructure) have altered the elevation of the salt marsh surface, changing the topography and morphology of these ecosystems. This study establishes and assesses means to document and analyze these impacts using Unoccupied Aerial Vehicle (UAV) based remote sensing to model platform topography. This thesis’s first and primary study presents and compares methods of producing high-resolution digital terrain models (DTMs) with UAV-based Digital Aerial Photogrammetry (DAP) and Light …
Buffering Effects Of Negative Intergroup Contact Through Complex Social Identities, Liora Morhayim
Buffering Effects Of Negative Intergroup Contact Through Complex Social Identities, Liora Morhayim
Masters Theses
Although negative intergroup contact occurs less frequently than positive contact, negative contact can more strongly influence outgroup attitudes and behaviors due to the effect of category salience in the generalization process. The present study (N =306) tests whether being aware of an outgroup member’s complex social identity will serve as a buffer against the adverse impact of a negative intergroup contact experience on outgroup attitudes. In a 3X2 between-subjects design, social identity complexity (SIC) of an outgroup confederate (high versus low versus control) and the valence of contact (neutral versus negative) were manipulated. Participants interacted with an outgroup confederate …
Structural Racism, Black Out-Group Preference, And Mental Health, Alexander J. Kellogg
Structural Racism, Black Out-Group Preference, And Mental Health, Alexander J. Kellogg
Masters Theses
Structural racism has increasingly been implicated as a root cause of racial disparities in health and well-being. Specifically, areas where White Americans hold more negative attitudes toward Black Americans have been associated with both anti-Black discrimination and poorer Black physical and mental health. However, previous research has relied on cross-sectional designs and has neglected the potential effects of Black community-level attitudes on mental health. We hypothesized that higher aggregate pro-White bias among White Americans would be associated with higher implicit out-group preference among Black residents living in the same communities, above and beyond the effects of traditional measures of structural …
Automated Identification And Mapping Of Interesting Mineral Spectra In Crism Images, Arun M. Saranathan
Automated Identification And Mapping Of Interesting Mineral Spectra In Crism Images, Arun M. Saranathan
Doctoral Dissertations
The Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) has proven to be an invaluable tool for the mineralogical analysis of the Martian surface. It has been crucial in identifying and mapping the spatial extents of various minerals. Primarily, the identification and mapping of these mineral spectral-shapes have been performed manually. Given the size of the CRISM image dataset, manual analysis of the full dataset would be arduous/infeasible. This dissertation attempts to address this issue by describing an (machine learning based) automated processing pipeline for CRISM data that can be used to identify and map the unique mineral signatures present in …
Local Governmental Collective Action And Mandated Policy Implementation, Michael D. Roberts
Local Governmental Collective Action And Mandated Policy Implementation, Michael D. Roberts
Doctoral Dissertations
Groundwater depletion is a global concern. Around the world, groundwater supplies more than half the water used for agriculture and human drinking. Many other species and ecosystems are supported by groundwater and rely on the integrity of groundwater and surface water connections. Like many social and environmental problems, addressing the overextraction of groundwater requires collective action across governmental authorities and jurisdictions. To date, there are few examples of successful, voluntary groundwater management. To steer collective action at the local level, higher levels of government often use policy mandates. This dissertation examines the implementation of one such mandate. California’s Sustainable Groundwater …
Framing Fanart, E J. Nielsen
Framing Fanart, E J. Nielsen
Doctoral Dissertations
My dissertation, “Framing Fanart,” broadly theorizes media fanart, a form of transformative work that is enormously popular, transnational and transcultural, and at its heart an engaged response to a piece of media. Through physical and digital archival research, discourse analysis, and qualitative research methods, I consider specific examples of how fanart functions within these different framings. This work is some of the first to consider fanart broadly as both a lens through which to view patterns of cultural production and a discrete artefact which merits serious consideration as artwork in its own right.
Associations Between Early Childhood Sleep, Memory Function, And Brain Development Across The Nap Transition, Sanna Lokhandwala
Associations Between Early Childhood Sleep, Memory Function, And Brain Development Across The Nap Transition, Sanna Lokhandwala
Doctoral Dissertations
Preschool-age children often distribute their sleep across a midday nap and overnight sleep. Skipping the nap is suggested to increase the duration and depth of deep sleep (i.e., slow wave activity; SWA). Moreover, missing the midday nap has been shown to impair learning processes. This may be because children’s brains at this point in development are immature, necessitating the intervening nap period to strengthen memories before they are forgotten. Nonetheless, at some point during the preschool years, many children begin transitioning naturally out of napping. It is unclear whether the memory benefits of overnight SWA after a skipped nap depend …
Online Fan Communities: Welcoming Behavior, Brand Community Markers, And Multiple Identities In Sports Fandom, Blaine R. Huber
Online Fan Communities: Welcoming Behavior, Brand Community Markers, And Multiple Identities In Sports Fandom, Blaine R. Huber
Doctoral Dissertations
Online fan communities have revolutionized the way sport consumers engage with fellow fans and the sports product. The traditional regional boundaries that once characterized sports fandom have been mitigated by the emergence of new media, social media platforms, and online fan communities. This dissertation explores the non-geographically bound nature of contemporary sports fan communities, examining the evolving dynamics of fan behavior in the digital age. In Study 1, an interactional perspective is employed to explore online fan socialization. The focus is on how new fans' self-presentation influences acceptance within NFL team-specific Reddit communities. Utilizing data mining, textual analysis, and qualitative …
The Impacts Of Environment And Host Evolutionary Relationships On Lemur Microbiota, Rachel B. Burten
The Impacts Of Environment And Host Evolutionary Relationships On Lemur Microbiota, Rachel B. Burten
Doctoral Dissertations
Recent studies have shown that the mammal microbiome is modified by environmental conditions, and that reduced microbiome functionality is associated with host health issues. Microbiome data in wild and captive primate populations can therefore be used to assess their health as they encounter a variety of environments. Comparative studies of the microbiome can also inform disease ecology, conservation, and captive management strategies tailored to different primate species. Therefore, this study examines how the hair, oral, and gut microbiota of nine wild and captive lemur species are determined by host phylogenetic relationships and host environment. I found that host species identity …
