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.

The Dallas-Fort Worth International (DFW) Airport is located in a densely urbanized area with one of the fastest-growing populations in the U.S.A. The airport property includes a large tract of "protected" riparian forest that is unique to the urban surroundings. This dissertation explores variables that influence the benthic macroinvertebrate community structure found in urbanized prairie streams that were initially assessed by the University of North Texas (UNT) Benthic Ecology Lab during four, non-consecutive biomonitoring studies (2004, 2005, 2008, and 2014) funded by the DFW Airport. Additionally, land use analysis was performed using 5-meter resolution satellite imagery and eCognition to characterize the imperviousness of the study area watersheds at multiple scales. Overall, flow conditions and imperviousness at the watershed scale explained the most variability in the benthic stream community. Chironomidae taxa made up 20-50% of stream communities and outperformed all other taxa groups in discriminating between sites of similar flows and urban impairments. This finding highlights the need for genus level identifications of the chironomid family, especially as the dominant taxa in urban prairie streams. Over the course of these biomonitoring survey events, normal flow conditions and flows associated with supra-seasonal drought were experienced. Prevailing drought conditions of 2014 did not …

In urban environments, ozone air pollution, poses significant risks to respiratory health. Fixed site monitoring is the primary method of measuring ozone concentrations for health advisories and pollutant reduction, but the spatial scale may not reflect the current population distribution or its future growth. Moreover, formal methods for the placement of ozone monitoring sites within populations potentially omit important spatial criteria, producing monitoring locations that could unintentionally underestimate the exposure burden. Although air pollution affects all people, the combination of underlying health, socioeconomic and demographic factors exacerbate the impact for socially vulnerable population groups. A need exists for assessing the spatial representativeness and data gaps of existing pollution sensor networks and to evaluate future placement strategies of additional sensors. This research also seeks to understand how air pollution monitor placement strategies may neglect social vulnerabilities and therefore, potentially underestimate exposure burdens in vulnerable populations.

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.

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 …

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.

This study examined the influence of instructional technology on Spanish as a Foreign Language (SFL) vocabulary acquisition and the intrinsic motivation language learners present while learning vocabulary in a second language. A quasi-experimental design helped determine the impact of the instructional technology intervention using Quia and Quizlet to learn vocabulary over direct instruction. A nonrandom convenience sample of (N = 47) participants was divided into the experimental group (n = 25) and control group (n = 22). Data was collected from face-to-face interactions. Participants were secondary Spanish two students, ages 14–17, and from a north Texas public school. I taught 10 lessons over 10 days during a 30–45-minute instructional technology or direct instruction activity independently. The findings revealed whether the strategies, (a) instructional technology or (b) direct instruction, have a significant impact on Spanish vocabulary acquisition and student intrinsic motivation. The study's findings were derived from independent t-tests, which indicated that using instructional technology did not impact vocabulary acquisition over participants learning through a direct instruction method. Student intrinsic motivation was also not impacted. The analysis determined no significant impact between instructional strategies or the student's intrinsic motivation while learning vocabulary in a second language. While this study provides practical …

Fort Worth Stories is a collection of thirty-two bite-sized chapters of the city’s history. Did you know that the same day Fort Worth was mourning the death of beloved African American “Gooseneck Bill” McDonald, Dallas was experiencing a series of bombings in black neighborhoods? Or that Fort Worth almost got the largest statue to Robert E. Lee ever put up anywhere, sculpted by the same massive talent that created Mount Rushmore? Or that Fort Worth was once the candy-making capital of the Southwest and gave Hershey, Pennsylvania, a good run for its money as the sweet spot of the nation? A remarkable number of national figures have made a splash in Fort Worth, including Theodore Roosevelt while he was President; Vernon Castle, the Dance King; Dr. H.H. Holmes, America’s first serial killer; Harry Houdini, the escape artist; and Texas Guinan, star of the vaudeville stage and the big screen. Fort Worth Stories is illustrated with 50 photographs and drawings, many of them never before published. This collection of stories will appeal to all who appreciate the Cowtown city.

Changing Perspectives charts the pivotal period in Houston’s history when Jewish and Black leadership eventually came together to work for positive change. This is a story of two communities, both of which struggled to claim the rights and privileges they desired. Previous scholars of Southern Jewish history have argued that Black-Jewish relations did not exist in the South. However, during the 1930s to the 1980s, Jews and Blacks in Houston interacted in diverse and oftentimes surprising ways. The distance between Houston’s Jews and Blacks diminished after changing demographics, the end of segregation, city redistricting, and the emergence of Black political power. Allison Schottenstein shows that Black-Jewish relations did exist during the Long Civil Rights Movement in Houston.

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 …
