A Multi-Proxy Approach to Identifying Marine Overwash Sedimentation and Terrestrial Flood Sedimentation in a Coastal Lake in Southeastern Texas

This research project focuses on using a multiproxy approach to discriminate between overwash and non-hurricane marsh sediments within the bed of a coastal lake. 3 marsh cores were collected in an area of McFaddin National Wildlife Refuge just south of Clam Lake that are known to contain 4 hurricane overwash deposits, Ike, Rita, Carla, and Audrey. LOI and XRF analysis were used to determine the signature of the hurricane overwash layers. 3 more cores were collected from Clam Lake where there are no visible sand layers. The elemental signature of the overwash layers found in the marsh cores was used to run a hierarchical cluster analysis on the lake cores. This was able to determine the effectiveness of XRF's ability to distinguish between hurricane overwash and marsh sediments. The combination of cluster analysis, LOI, and XRF can tentatively identify hurricane overwash deposits in a coastal lake, however, it is more successful in the marsh cores. Results in the lake cores are somewhat inconsistent and uncertain, possibly because there may have not been enough overwash deposits to identity or that the XRF analysis needs more distinct sand layers to distinguish between overwash and marsh.

Building Resiliency: The Role of Faith-Based Organizations in the Trauma-Affected Community of Santa Fe, Texas (open access)

Building Resiliency: The Role of Faith-Based Organizations in the Trauma-Affected Community of Santa Fe, Texas

On May 18, 2018, a shooter entered Santa Fe High School, killing eight students and two teachers. Using ethnographic methods, this research examines the role of faith, rituals, language, and symbols in the trauma-affected community during the response, recovery, and resiliency efforts as perceived by the Santa Fe community and those impacted by the tragedy. Qualitative data collected from 100 individuals ages of 17-84 illustrated how historical trauma, community culture, and faith-based organizations impact community resiliency and how illusions of a homogenous view of the community left many feeling shocked, divided, forgotten or muted.

Diversity Without Inclusion: The Experience of Female Graduate Students of Color at a Minority Serving Institution

Graduate education can be psychologically taxing, and the academic tasks that graduate students are required to perform can cause a great level of stress, insecurity, and uncertainty. The unique experiences that female students of color face at the intersections of gender, race, and class may have negative effects on their academic performance and attainment. This research explored the experiences of discrimination among the female African American/Black and Hispanic/Latina graduate students and their coping strategies to survive in the program of study at the University of North Texas (UNT), as a minority serving institution (MSI). A narrative research method was applied and 13 in-depth interviews were conducted using a semi-structured interview protocol. The findings showed the participants experienced various types of intragroup and intergroup discrimination based on the intersections of their multiple identities, especially race, gender, and socioeconomic status. The findings of this study revealed structural discrimination that participants experienced through their education; starting with their low income neighborhood where they were raised and the discrimination at the university. They perceived that minorities are not represented in the management and faculty positions, and there is an inadequacy of support resources and lack of racially sensitive advising services for female graduate students …

Engine Running: Essays

Engine Running: Essays is a collection of creative nonfiction that explores, in parts, a persona's distancing from home and self against the backdrop of an increasingly fractured family doing the same. Through a variety of forms, the essays seek to balance themes like loss, self-discovery, and manhood in reflections on the role of childhood memory, the early revelations and experimentation of sexuality, and the carving-out of personal identity in West Texas.

GIS-Based Analysis of Local Climate Zones in Denton, Texas (open access)

GIS-Based Analysis of Local Climate Zones in Denton, Texas

This study implemented a GIS-based analysis of local climate zones (LCZ) in Denton, TX with data sets from 2009, 2011, 2015, and 2016. The LCZ scheme enables evaluation of distinct regions' thermal characteristics with greater granularity than conventional urban-rural dichotomies. Further, the GIS-based approach to LCZ mapping allows use of high-resolution lidar data, the availability of which for the study area enabled estimation of geometric and surface cover parameters: height of roughness elements, sky-view factor, and building surface fraction. Pervious surface fraction was estimated from National Landcover Database impervious imagery. A regular grid was used to estimate per-cell mean values for each parameter, and with a decision-making algorithm (if/then statements) two maps were produced (2011 and 2015) and six LCZ identified in each: LCZ 6 (open low-rise), LCZ 8 (large low-rise), LCZ 9 (sparsely built), LCZ A (dense trees), LCZ B (scattered trees), and LCZ C (bush/scrub). Post-processing was carried out to ensure identified zones met the spatial minimum for qualification as LCZ. Landsat Collection 2 Level 2 surface temperature products from various seasons of 2011 and 2015 were acquired to examine LCZ thermal differentiability, and preliminary surface urban heat island intensity values were estimated. Particular attention was afforded to …
