Spatial-Temporal Assessment of Irrigation Application Changes and Soil Moisture Analysis Using SMAP Maps
Due to inadequate long-term and large-scale observation approach for observation of soil moisture across the globe, this study intends to unveil the importance of using simulated soil moisture fields from land surface models, forced with observed precipitation and near-surface meteorology in monitoring drought and formulating effective water management practices for continued production irrigation applications. This study shows that socio-economic and ecosystem effects can be determined by evaluating spatial-temporal changes in irrigation applications. Thus, it facilitates understanding of the importance of water management and how water, energy, and carbon flows protect our climate and environment. By using Soil Moisture Active Passive (SMAP) in monitoring soil moisture, the information obtained is critical in providing early drought warnings, particularly in those parts of the United States that experience flash agricultural droughts. Further, this study highlights that frequent and reliable soil moisture measurements from SMAP helped improve the predictive capability of weather and climate models.
The Study of Network Governance in Continuum of Care (CoC), Homeless Service Networks in the US: Institutional Collective Action Framework
The dissertation investigates the form of network governance in the context of U.S. homeless service networks (namely continuum of care programs; CoCs). This research examines CoC homeless service networks by applying the institutional collective action (ICA) perspectives to understand the forms of network governance as a reflection of network context. The ICA perspective has been applied to understand the rational behavior of network members for the network governance form to mitigate the collective action problems. The ICA perspective helps understand why network members accept specific governance structures with their expectation to maximize the benefits and minimize the costs and uncertainty in their process of collaboration. This dissertation uses the data of CoC networks and point in time data from the U.S. Department of Housing and Urban Development in 2019 and Census. The data developed for this study offers the homeless incidences, geographical characteristics, and governance structure based on the contact information. For an in-depth understanding, interview by CoC leaders was integrated. This dissertation consists of four essays about 1) Literature review on network governance and the theoretical argument in the ICA framework, 2) Background and network governance of the U.S. homeless service networks, 3) Factors affecting the choice of network administrative organization (NAO) form, and 4) Interviews by the representatives of CoC networks. The findings inform us of the governance structure for the effective service provisions and coordination of actions of network members and about why and how network organizations choose a form of network governance.
Credentialing in Higher Education: A User Experience Study of the University of North Texas' Student Learner Record
This was a mixed-method user-centered study regarding the University of North Texas's student-owned learner record and credentialing system. Through methods of quantitative and qualitative inquiry, student perceptions were unearthed and recommendations to improve the system were provided.
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 issues regarding data quality and classifier threshold adjustment.
Socialization of the Strong Black Woman Schema
Black mothers socialize their daughters to embody the strong Black woman (SBW) schema to help them navigate gendered racist oppression. While research indicates that ascribing to the SBW schema offers Black women psychosocial benefits (e.g., increased self-esteem), identifying with the SBW schema has been linked to several negative psychological outcomes (e.g., anxiety, depression, and stress). Considering the evidenced negative implications associated with identifying with the SBW schema on Black women's mental health, the current study had three aims: (1) investigate the socialization messages Black women received about strong Black womanhood, (2) explore the extent to which they identified with these messages, and (3) assess the implications of this socialization on Black women's functioning. To address these aims researchers conducted semi-structured interviews with 11 Black college women (Mage = 20.09; SD = 1.04). For this manuscript, we extracted data pertaining to aim one and analyzed this data using a consensual qualitative research (CQR) data approach. Findings revealed messages Black women were given about strong Black womanhood (i.e., know your worth, depend on yourself, overcome societal barriers, little to no messages about strong Black womanhood, and additional responses) and illuminated behaviors mothers modeled that exemplified strength (i.e., self-sufficient, preserving, caretaking, and additional responses). Findings derived from this study have the potential to inform clinical intervention with Black women and, more specifically, provide insight as to how clinicians may work with Black women to mitigate the impact of the SBW schema on their mental health.
Impact of Instructional Technology on Student Motivation and Vocabulary Knowledge
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 methods to implement in a classroom for language learners, the recommendations are intended for all educators to guide and teach language development and implement instructional lessons that influence students' vocabulary acquisition using motivating strategies.
Multi-Tier Systems of Support and Their Impact on a Title I School
The purpose of this study was to examine a novel campus-based multi-tier systems of support (MTSS) framework. The framework included a standard-response protocol approach to response to intervention (RTI), integrated with a reversed process to professional learning communities, to support learning for students who were struggling to learn. Using a causal-comparative research design, a secondary analysis of quantitative data from one Title I school of approximately 500 students during the 2016-2018 school years was conducted to determine the level of impact MTSS had on reading achievement. Independent and paired samples t-tests were used to analyze iStation indicators of progress reading scores, resulting in statistically significant results. Kindergarten through 5th grade students' reading scores were significantly higher after one year of MTSS intervention than students who did not receive MTSS. One year of MTSS intervention had a statistically significant impact on both early and intermediate readers. Early readers, who began below grade level, performed significantly higher in reading achievement after just one year of MTSS as well. Intermediate readers, who began on or above grade level did not perform significantly higher in reading achievement after one year of MTSS, however. Possible long-term implications for MTSS were analyzed by comparing one year to two years of MTSS intervention. A consistently significant increase in reading scores occurred, suggesting growth that took place from one year of MTSS was enhanced by an additional year of MTSS. This novel MTSS framework could be used by campus leaders as an intervention to provide equitable learning for all students and yield statistically significant results in reading achievement in one school year. Additional research examining the impact of MTSS on Tier 1 intermediate readers receiving enrichment is recommended.
Divided-Tenure, Divided Recovery: How Policy and Land Tenure Shape Disaster Recovery for Mobile Homeowners
People who live in mobile homes have heightened vulnerability to disasters, due in part to mobile homes increasingly occupying high-hazard risk lands and the precarious ownership status known as divided-tenure. Divided-tenure is when an individual owns a mobile home and rents the land underneath. To identify the challenges associated with divided-tenure and disaster recovery from a policy perspective, this study analyzed the content of key HUD policies and performed a comparative policy analysis of purchase opportunity laws (requirements of landowners to give mobile homeowners an opportunity to purchase the property their home resides on) in three states: California, Florida, and New York. Content analysis indicated few direct references to mobile homes. Inconsistencies and confusing messaging were found in the existing federal guidance. The lack of consistent terminology and guidance on addressing divided-tenure, limits mobile homeowner's options for disaster recovery, including eligibility for federal disaster aid and potentially participation in relocation or buyout programs. The three selected states' purchase opportunity laws reviewed in this study were rated as weak. Policies lacked alignment with federal documents and opportunities for mobile homeowners were difficult to navigate. A pathway to land ownership could give mobile homeowners more control over their disaster recovery options, but current laws still limit that ability. This study and future work have the potential to help mobile homeowners, an understudied yet growing population, experience a more equitable disaster recovery, which currently is lacking, based on the reviewed federal and state policies.
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.
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 of color. The findings of this research showed that a large majority of the participants perceived UNT as an institution with diversity but without inclusion. They had used two strategies to respond to the incidents of discrimination; building resilience to fulfil a purpose, and self-care and building support system. This research concludes that UNT is in need to create a climate that is more accessible, caring, and supportive for female graduate students of color. Implications for practice and policy are discussed.
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.
Benevolent Assimilation: The Evolution of United States Army Civil Affairs Operations in the Philippines from 1898 to 1945
The history of the United States' occupation and administration of the Philippines is a premiere example of the evolution of the American military's civil administrative approach as it evolved from simple Army security in 1898, through an evolving ‘whole-of-government' method, to what was practically the full military administration of the country by March 1945. The second liberation and subsequent administration of the Philippines by the United States Army was unique, not simply because of the physical characteristics of the operations, but more so because of the theater commander, General Douglas MacArthur. MacArthur used a rather self-reliant approach that rejected much of the direction from various authorities in Washington and adopted independently authored local solutions, but he took advantage of external resources when necessary. Ultimately the United States Army Forces in the Far East (USAFFE) under his command had to accept external direction to gain external resources. The Army's civil administrative planning and execution in the Philippines in 1944-1945 was the direct result of the social, political, economic, and military relationships between Americans and Filipinos from 1898 to 1944, much of which involved MacArthur, and the institutional changes that developed from these interactions. The result was civil administration that met the local and immediate requirements suitable for the conditions at hand. By August 1945 the Army ended civil affairs operations and transferred responsibility to the Commonwealth government of the Philippines and the Foreign Economic Administration (FEA).
Ozone Pollution Monitoring and Population Vulnerability in Dallas-Ft. Worth: A Decision Support Approach
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.
Biomonitoring at Dallas-Fort Worth International Airport: Relating Watershed Land Use with Aquatic Life Use
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 negatively influence stream communities, allowing this study to capture the long-term natural (temporal) variability of urban prairie stream communities. Such long-term studies are imperative for discerning between stream impairment versus natural variation, especially as droughts become more frequent and severe.
Exploring the Relationships between Psychopathic Traits and Ethnocentric Attitudes
The current study employed both a variable- and person-centered approach to analyze data taken from a large sample of U.S. adults (N = 602, 59% males). For the former, structural equation modeling was utilized to empirically articulate the links between the four facets of psychopathy (interpersonal, affective, lifestyle, antisocial) and the six facets of ethnocentrism. For the person-centered approach, descriptive discriminant analysis was used to assess for differences in psychopathic trait profiles between those elevated or low in ethnocentric attitudes. Consistent with expectations, the affective dimension positively predicted denigration of out-group members whereas the lifestyle domain negatively predicted all facets of ethnocentrism. Unexpectedly, the antisocial facet positively predicted group cohesion and devotion towards one's ethnic in-group. Additionally, those elevated in ethnocentrism had higher interpersonal and affective scores and lower lifestyle scores relative to those low in ethnocentric attitudes. Results are discussed in the context of risk assessment for hate-based violence and the overlap in the nomological network of psychopathy and prejudicial attitudes.
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.
Intersectional Analysis of Perceived Racism as a Determinant of Children's Mental Health
Youth in the United States are experiencing a steep increase in mental health issues. Concurrently, unique political, economic and social dynamics in the U.S. make the circumstances of nonwhite children's mental health partially contingent on experiences of racism. In this study, I examine the relationship between racial minority children's mental health and perceived racism, while also examining the moderating effects of gender on this relationship. I first review prior research which suggest that racism is a salient determinant of several health outcomes among racial minorities and racial minority children, including depression and anxiety. I then review research on both gender and racial socialization and posit possible implications of these differentials on mental health. Considering both the racialized and gendered factors contributing to youth's mental health outcomes, this study fills a gap in previous research by exploring the differences by gender and race in the effect of perceived racism on children's mental health. I use data from the National Survey of Children's Health from 2016 to 2019. Using average marginal effects, calculated from a series of logistic regression models predicting depression, anxiety, behavioral and emotional problems, I find support for previous research which suggests that perceived racism predicts poor mental health among non-white children. I elaborate further by adding the intersection of gender, splitting and comparing the sample across race and gender subgroups. I find considerable variety in the effects of perceived racism across race and gender, such that Latina and Asian girls who experience racism are at heightened risk for being diagnosed with mental health conditions.
Saudi Mothers' Experiences Maintaining Their Young Children's Arabic Language and Islamic-Saudi Identity
As more Saudi individuals temporarily settle in the United States to pursue higher education, it becomes increasingly important to understand the impact this experience has on their families. The purpose of this qualitative instrumental case study was to examine Saudi mothers' experiences and motivations after transitioning to life in the United States. The main research question was: What are Saudi mothers' experiences of supporting their children maintaining and developing Arabic language skills and Islamic-Saudi identities while they are learning English and Western culture in U.S. schools? The sub-questions of the study were: Why do Saudi mothers in this study want their children to learn the Arabic language and culture? What are their concerns? What are the challenges Saudi mothers face in socializing their children to develop their Islamic-Saudi identity? What practices do mothers use to help their children preserve their Arabic language and develop the Islamic Saudi-identity while growing up in the United States? This study was conceptually framed within the theories of parenting style and acculturation. Participants in the study were five Saudi mothers pursuing higher education in Texas. Data were collected through three semi-structured interviews and four audio journals with each participant, and a focus group with the five mothers. Data were analyzed through a thematic analysis. The results of this study provide insights into the experiences, motivations, practices and challenges Saudi mothers face while raising their children in two cultures. This study contributes to the growing research in an era of increased population mobility, specifically by providing awareness of the needs and values of Saudi families who have been understudied in the field of early childhood education.

When They See Us: The Lived Experiences of Christian African American College Males at a Christian Predominantly White Institution (PWI) in the South
The purpose of this phenomenological study is to highlight the lived experiences of Christian African American college males attending a Christian predominately White institution (PWI) in the South. Through in-depth personal interviews, I offer insights into this specific student population's experience. Furthermore, I provide recommendations for key stakeholders at Christian PWIs in the South as they strive to create an inclusive campus environment. The ultimate goal of the research is to aid in the recruitment and retention of this particular student population.
Crafting Downtown Denton: An Exploration of Craft Beer Consumption as an Activity in Denton, Texas
Craft beer as a cultural phenomenon coincided with the revitalization of downtown Denton, Texas. Much of the existing literature on craft beer and its relation to place focuses on breweries rather than bars. This exploratory study aims to explain why people consume craft beer, what factors influenced its popularity in Denton despite little beer production, and to explore considerations for the promotion of Denton as a craft beer destination and making downtown an inclusive space. Data was collected through interviews, participant observation, and a survey. Findings indicated that craft beer consumption in Denton is largely related to perceptions of community, localism, and knowledge seeking. The ethos of the craft beer industry closely aligned with participants' perceptions of Denton as a city.
Unlocking Digital Literacy: A Multiple Case Study of Digital Literacy Instruction and the Interactive Decision Making of Teachers in a Texas Charter School
The rapid expansion of computers and digital technology requires citizens to be digitally literate. Teachers must prepare students for a digital world despite the lack of consensus on a definition or its components. This multiple case study explored the digital literacy instruction and interactive decision making of teachers with varied levels of expertise. Each participant completed a survey and the General Decision Making Style Questionnaire prior to a series of interviews and classroom observations. Findings from a qualitative analysis of the data suggest variations in the use of digital literacy components during instruction and that skills are related to one another. Findings also indicate similarities and differences in interactive decision making and teaching expertise behaviors related to instruction. Based on these findings, recommendations to better promote digital literacy are directed toward teachers, administrators, teacher preparation institutions, and future researchers. Current events emphasize the need for increased efforts in turning the key of digital literacy for students.
Information Seeking Behaviors of Transitioning Veterans When Job Hunting in North Texas
This study explored a part of our population that can be misunderstood, marginalized, and underserved: veterans who are seeking to transition from the military to employment in North Texas. At the time of this research (before the COVID-19 pandemic), overall unemployment in North Texas was only 3.9%.Veteran unemployment was calculated at approximately the same before considering the underemployed veterans or those who have given up finding employment (and before the COVID-19 global pandemic), and that calculation likely exceeds 16-18% according to the Texas Workforce Commission. By understanding the information-seeking behaviors of the veteran population targeting North Texas for future employment, their ability to find useful information for successful relocation, attainment of employment, and the resources that enables their sense-making processes, the services provided to veterans seeking employment can be improved. Further understanding can be gained by using a qualitative approach that references Dervin's sense making model (SMM) as the framework. The revelations and conclusions can be used to improve existing programs, inspire new programs, and provide answers that are useful to the Veteran's Administration (VA), other veteran-focused organizations, policymakers, non-profits who serve veterans, veterans themselves, and future employers who enable successful transitions by providing satisfying and inclusive employment opportunities for veterans.
Psychedelia in the United States: An Ethnographic Study of Naturalistic Psychedelic Use
The client for this study, the Entheogenic Research, Integration, and Education (ERIE), was interested in the use of anthropological methods to examine the experiences of people who use psychedelics beyond the clinical setting. Through collaborative discussions with the client, we decided that the central questions guiding this research are to understand the various reasons why people consume psychedelic substances across the United States as well as examine the self-reported influences of psychedelics in various areas of participants' life and identity. Participants were recruited using stratified sampling and were given a confidential, online survey that also provided an option to arrange a semi-structured interview. In total, there were 103 completed survey responses and 25 interviews. The results of this research indicate that the reasons for participants' psychedelic use often change over time from strictly recreational or out of curiosity to intentions based on therapeutic and psychospiritual development. Additionally, the majority of both survey and interview participants believed their psychedelic use to have had a transformative influence on their health and well-being, perception of nature, identity, spirituality, and creative expression of art and music. Another theme uncovered in this research is the impacts of punitive drug laws on psychedelic use such as creating barriers to availability, fear of arrest and incarceration, and lack of social support due to the stigma associated with psychedelic substances.
The Lynching of Women in Texas, 1885-1926
This work examines the lynching of twelve female victims in Texas from 1885 to 1926.
The Role of Faith-Based Congregations during Disaster Response and Recovery: A Case Study of Katy, Texas
When governments are unable or unwilling to provide necessary relief to communities, local faith-based congregations (FBCs) step in and fill the gap. Though shown to provide for so many needs following disaster, FBCs have largely been left out of the institutional emergency management cycle. The aim of this study was to explore the role of FBCs in the disaster response and recovery process and investigate how recovery impacts FBCs. The primary objective of this study is to gain a better understanding of FBCs and how to better integrate them into the formal emergency management process.The main questions were as follows: First, what is the role of FBCs during the disaster recovery process? Second, how do FBCs change (temporarily and permanently) during disaster recovery, and what factors may promote or inhibit change? To answer these questions, qualitative semistructured interviews were held to develop a case study of Katy, Texas and its recovery from Hurricane Harvey of 2017. The applied and conceptual implications resulting from this study, which apply to FBCs, researchers, emergency managers, and policy makers, highlight the opportunity to better incorporate FBCs formally into emergency management practices.
That Isolation Creeps In: Exploring the Intersection of Public Transit and Mental Health in Dallas County, Texas
The primary goal of the research project was to organize a community needs assessment, which culminated in a report attached in the appendix. Data from sixteen interviews with community leaders involved in mental health promotion throughout Dallas County, Texas was used as the foundation of the professional report. This data revealed several key barriers faced by those with mental illness in their ability to access mental health services in Dallas County. The information gathered prompted further exploration into the intersection between public transit and mental health. Transit became the focus of this work when it came up as simultaneously a barrier to care and mode of prevention in the majority of the interviews. Interestingly, Dallas County has public plans to address transit related disparities; however, their intervention pulls from strategies determined to be ineffectual among the poor and disenfranchised. In this work we explore community needs and the civic culture of Dallas with a specific focus on transportation.
A Case Study Assessing Performance Differences between Economically Impacted African American and White Students in High School Algebra II Classes in the Tucson Unified School District
This case study investigated the phenomenon of the black white test score gap by seeking to determine if there was a difference in the academic performance of African American students and their White peers. The determination of student academic performance was made using scores from second semester Algebra II classes at two high schools in the Tucson Unified School District. The data covered three academic years and was analyzed via SPSS (independent samples t-test, ANOVA, and a pairwise analysis) and content analysis for qualitative analysis. Findings revealed that there was no variance in the scores of African Americans and their White peers attending an affluent school; however African Americans attending a low-income school scored lower than all groups that were compared in this study.
Measuring College Readiness: Developing a System of On-Track and Off-Track Metrics for Texas High School Students
The purpose of this study was to analyze and determine the predictive power of individual and a combination of different indicators that are used to determine college readiness. For this study a logistic regression analysis was conducted due to the dichotomous nature of the dependent variable. The dependent variable for the study was the earning of a post-secondary credential. The independent variables included high school diploma type, Advanced Placement course taken, Advanced Placement test performance, SAT performance, ACT performance, a multidimensional index made up of all the variables, and high school GPA. The study found that high school GPA had the strongest odds ratio, Exp(B), for the participants earning a post-secondary credential (Exp(B) = 6.597), followed by diploma type (Exp(B) = 6.316), taking an Advanced Placement course (Exp(B) = 4.368), earning at least one qualifying Advanced Placement test score (Exp(B) = 3.846), a multidimensional index (Exp(B) = 2.318), ACT score (Exp(B) = 1.161) and SAT score (Exp(B) = 1.003). Future analysis is needed by using live data of student's college performance, stratifying the data to account for differences in post-secondary performance by different racial and socio-economic groups, and studying the effects of the State of Texas' chosen college readiness variables.
Refugee Employment in Dallas, TX: Experiences and Barriers
Changing national policies in recent years represent an unprecedented attack on refugee resettlement in the United States. In this period of political and social uncertainty, understanding the barriers to refugee economic integration is more critical than ever. Following a review of existing literature on refugee resettlement and economic integration, this research assesses experiences of refugee employment in Dallas, Texas—one of the cities that resettles the most new refugees nationwide—through investigating the experiences of four key populations: resettled individuals themselves (including refugees, asylees, and SIVs), resettlement caseworkers, third-party staffing agencies, and the management/HR staff of refugee employers. These diverse perspectives will assist in understanding the structural constraints that shape refugee employment services, as well as the interaction of these various individuals and organizations as parts of a dynamic system. The project also aims to explore employers' experiences of hiring refugees and working with resettlement programs, as the perspectives of entrepreneurs and the business community are those most likely to influence the attitudes of legislators and encourage renewed support of resettlement in Texas. The conclusion of this study offers recommendations for how resettlement organizations can navigate the ambiguities of a resettlement system driven by neoliberal economics and a push for rapid employment while supporting clients' successful economic integration and avoiding the exploitative work relationships that have come to characterize refugee employment in many areas.
Early Music Audiences: A Survey and Analysis of Early Music Consumers in Texas
Texas has a rich tradition of Early Music ensembles that dates back to 1969. However, there is little reliable information based on statistical data collection and analysis concerning Texas Early Music consumers. Little is known about why they attend Early Music performances or other important factors that affect the Early Music industry. Through the use of an extensive survey and accompanying statistical analysis, this study answers many questions regarding Early Music consumers in the State of Texas. This study collected demographic and psychographic data in January 2020 about the Early Music concert-going public in three major Texas cities - Dallas, Austin, and Houston. Other factors were identified in two primary areas: audience characteristics and ticket pricing practices.
Effect of Barrier Height on Magnitude and Character of Hurricane Harvey Washover Fans, Matagorda Peninsula, Texas
This study uses topographic profiles, washover fan volumes, and shoreline retreat rates to explore relationships between barrier types and Hurricane Harvey storm washover sedimentation. Pre- and post-Hurricane Harvey topographic profiles were created on 15 transects using Bare Earth LiDAR (2016) and surveyed elevations (2019). Depth and area of washover fan measurements were collected to estimate washover fan volumes. An inverse relationship was found between washover fan volume and pre- and post-storm barrier heights. Based on the topographic profiles, one section of shoreline had a scarp up to 3m high which blocked overwash, but appears to have increased shoreline erosion. In contrast, a low-lying section of shoreline generated relatively large washover fans, but experienced less shoreline retreat. Shoreline retreat was further quantified between 2014 and 2019 using Google Earth Imagery from 2014, 2016, 2017, and 2019 to track migration of the shoreline. The entire shoreline in the study area is undergoing relatively rapid retreat, but the results suggest that Hurricane Harvey increased erosional rates. The Colorado River Jetty borders the study area and may have acted as an anthropogenic barrier, likely reducing storm surge energy and contributing to marsh aggradation on transects in its close proximity. The study findings indicate that the identification and incorporation of other variables that influence washover magnitude would further the understanding of this complex natural system. The research results provide valuable information on the interaction of hurricane storm surge with natural and anthropogenic barriers, beach and dune erosion, and marsh aggradation along the coast of Texas.
Fire Eater in the Borderlands: The Political Life of Guy Morrison Bryan, 1847-1891
From 1847 to 1891, Guy Morrison Bryan was a prominent Texas politician who influenced many of the policies and events that shaped the state. Raised in his Uncle Stephen F. Austin's shadow, he was a Texas nationalist who felt responsible for promoting the interests of his state, its earliest settlers, and his family. During his nineteen years in the Texas Legislature and two years in the United States House of Representatives, he safeguarded land grants, supported internal improvements and education, and challenged northern hostility towards slavery. Convinced that abolitionists would stop at nothing to destroy the institution and Texas, he led his state's walkout of the National Democratic Convention in 1860 and became a leading proponet of secession. During the Civil War, he served as a staff officer, and his ability to mediate conflicts between local and national leaders propped up the isolated Confederate Trans-Mississippi Department. Finally as Speaker of the House, he helped oust Governor Edmund J. Davis in 1874 and "redeem" the state from Republican rule before convincing President Rutherford B. Hayes to adopt a conciliatory policy towards Texas and the South. Despite the tremendous influence Bryan wielded, scholars have largely ignored his contributions. This dissertation establishes his significance, uses his willingness to transfer national allegiances to consider nationalism--whether Texan, American, or Confederate--in the United States-Mexico Borderlands, and sheds light on neglected subjects like the role of staff officers in the Civil War.
What Would a Waterbird Do? An Annual Study of 13 Urban Wetlands in Frisco, Texas
Intention for this study is driven by finding patterns that may be shown to reveal primary factors of influence for the abundance and diversity of wetland birds. These correlations may be used to promote wetland management strategies for the benefit of waterbird species, and help illuminate current local wetland conditions for waterbirds, respectively. The idea is to help enliven individuals to become a more conscious steward and manipulator of our environment through incorporating structural and biological components into wetland development and management strategies, and broadly speaking, urban development practices.
A Mixed Method Inquiry into Student Academic Optimism: Validation of the Construct and Its Use to Give Voice to Latinx Student Experiences
This study examined student academic optimism in four diverse North Texas school districts. This study used a convergent parallel mixed methods design to analyze results of an online administration of the survey, and Latinx student responses to a focus group protocol derived from the survey. Quantitative results indicate the individual scales making up the construct align with previous research results. The three scales were found to be strongly and significantly correlated, indicating the potential for validation. Qualitative results indicate Latinx students' perceptions of their academic careers align with four themes. Latinx students are keenly aware of their teachers as a person, their school as a community, the intrusion of the outside world, and students as agents. Qualitative results support the importance of the three components of the construct, student trust in teachers, student academic press, and student identification with school. As a new source of data, combined with existing metrics of instructional effectiveness, student academic optimism could increase the ability of decision makers to improve the overall efficacy of school systems especially when addressing the persistent opportunity gaps for Latinx and other students of color.
Key Factors in Developing a Successful Bond Referendum in Texas School Districts
In May of 2002, Wichita Falls ISD, a district in Texas with a stagnate enrollment of 14,000 students for multiple years, asked for the community to support a $120 million bond to help cover the cost of four new elementary campuses and to maintain and upgrade aging facilities. The bond failed. Additionally, a 2004 bond failed again. Finally, in 2006, the district is finally able to pass a $60 million bond and only includes two new elementary campuses and no funding to address the aging facilities. At the same time, other districts in fast growing areas of Texas are able to pass school bonds with little to no issues. This begs the question, is there a formula for getting school bonds passed? The purpose of this study is to discover what key factors influence a bond package; to help find those answers, eight districts in Texas were selected, five considered to be a fast-growth district" and three considered to be no-growth district. The study used a qualitative research approach, using semi-structured interviews with 24 participants. After all factors were analyzed, a pattern and recommendation is developed for districts to follow allowing a high degree of success for school bonds.
In the Tall Grass West of Town: Racial Violence in Denton County during the Rise of the Second Ku Klux Klan
The aim of this thesis is to narrate and analyze lynching and atypical violence in Denton County, Texas, between 1920 and 1926. Through this intensive study of a rural county in north Texas, the role of law enforcement in typical and systemic violence is observed and the relationship between Denton County Officials and the Ku Klux Klan is analyzed. Chapter 1 discusses the root of the word lynching and submits a call for academic attention to violence that is unable to be categorized as lynching due to its restrictive definition. Chapter 2 chronicles known instances of lynching in Denton County from its founding through the 1920s including two lynchings perpetrated by Klavern 136, the Denton County Klan. Chapter 3 examines the relationship between Denton County Law Enforcement and the Klan. In Chapter 4, seasons of violence are identified and applied to available historical records. Chapter 5 concludes that non-lynching violence, termed "disappearances," occurred and argues on behalf of its inclusion within the historiography of Jim Crow Era criminal actions against Black Americans. In the Prologue and Epilogue, the development and dissolution of the St. John's Community in Pilot Point, Texas, is narrated.
The Power of Choice: An Examination of a Hybrid Recess/Tutorial Program at a Suburban High School in the Southwestern United States
A suburban district in the southwestern region of the United States created a choice-based program in which students have the opportunity to address their social, emotional, and academic needs through a mid-day period where they have the ability to attend tutorials or engage in a variety of club and social activities. Each day, students choose the activity that best serves their needs, be those academic, social, or emotional. In order to determine students' attitudes, opinions, and uses of the program in an effort to improve its effectiveness for student success, this qualitative study was planned to respond to the research questions: (1) how do students spend the emPower period? and (2) what are students' thoughts, attitudes, and opinions with regards to emPower? The research began by examining student responses to a previous principal survey asking their opinions on the program. Following the analysis of the survey, focus group sessions of five students from each high school grade were held to discuss student perceptions, choices, and uses of the program. The discussions were audiotaped and transcribed. Thematic data analysis resulted in themes of stress, social life, environment, regulations, choice and tutorials. Findings included a continuum of maturity evident with students' choices as they progressed in grade level; enhanced student decision making and self-reflection; cultivating positive student-teacher relationships. Student suggestions for the program involved extending the time length of the period, teaching younger students to use the program effectively, and updating the way the advisory class is taught to be more beneficial to students.
Analysis of Interrelationships between Climate Change and Cotton Yield in Texas High Plains
The Texas High Plains produces the most substantial amount of cotton in Texas. The region is a semi-arid area with limited precipitation, and it is, therefore, susceptible to climate change. Cotton production in the Texas High Plains is mostly dependent on irrigation to increase yield. The overall goal of this research was to study the interrelationships between climate change and cotton yield using correlation analysis and also to study how climate has changed in the region using trend analysis. A three-decade data (1987-2017) was analyzed to establish the relationship between climate change and cotton and also to determine how climate has changed in the area over the last 30 years. The research used precipitation and temperature data to assess climate change.The results of this research showed that annual mean temperature has lesser impacts on cotton yield, and the correlation between annual precipitation and cotton yield is insignificant. It also found out that high rates of temperature at the boll opening stage of cotton growth results in decreased cotton yield and that at the boll development and boll opening stages, precipitation is needed. Again, the research indicated that, on average, there had been a significant increase in temperature, but precipitation trends are insignificant. About 60% of cotton acreage in the area is irrigated. Therefore the research also found out that increasing trends of cotton yield may contribute to the decline of groundwater in the area.
Perceptions of Restorative Practices by Male Students of Color in Middle School
Zero-tolerance discipline policies have been in use in U.S. schools for almost 25 years. Since their enactment in the 1990s, researchers have found that zero tolerance disciplinary policies and practices can cause students to enter the school-to-prison pipeline. The purpose of this qualitative case study was to understand the perceptions of middle-school male students of color regarding the discipline process on a campus that supplemented zero-tolerance discipline with restorative practices (RPs). Additional intents of this study were to discover the challenges students encountered when they returned from a disciplinary alternative education program (DAEP) and determine whether RPs helped or hindered their transition to the home campus. Six middle-school male students of color who were placed at the district's DAEP and returned to their home campus participated in the study. The conceptual framework was based on Braithwaite's concept of stigmatized shame following an exclusion and Nathanson's human reactions to shame. The study yielded seven major themes: (a) student perceptions of exclusion, (b) behaviors related to exclusion from school, (c) human reactions to shame—attacking others, (d) human reactions to shame—avoidance, (e) the need for reintegration and acceptance, (f) traumatic events, and (g) dissonance in the discipline process.
The Administration of Unemployment Relief by the State of Texas during the Great Depression, 1929-1941
During the Great Depression, for the first time in its history, the federal government provided relief to the unemployed and destitute through myriad New Deal agencies. This dissertation examines how "general relief" (direct or "make-work") from federal programs—primarily the Emergency Relief and Construction Act (ERCA) and Federal Emergency Relief Administration (FERA)—was acquired and administered by the government of Texas through state administrative agencies. These agencies included the Chambers of Commerce (1932-1933), Unofficial Texas Relief Commission (1933), Texas Rehabilitation and Relief Commission (1933), Official Texas Relief Commission (1933-1934), Texas Relief Commission Division of the State Board of Control (1934), and the Department of Public Welfare (1939). Overall, the effective administration of general relief in the Lone Star State was undermined by a political ideology that persisted from, and was embodied by, the "Redeemer" Constitution of 1876.
Equitable Early Childhood Education for Young Bilingual Learners in North Texas: Examining Kindergarten Entry Assessments for Bilingual Children
A considerable amount of research has been done surrounding education in classrooms from kindergarten to Grade 12, but little research has been done surrounding early childhood education (ECE) beginning with birth to age 4. As a result, research is needed that examines interventions aimed to improve the quality of early childhood education for young bilingual learners at the earliest stages of schooling. The present study examines current efforts to serve the specific population of young bilingual children entering classrooms in an urban school district in North Texas. The focus of this study includes the access and examination of quality ECE programs (defined by the extent to which bilingual children have access to bilingual education programming). The present study also observes the visibility of young bilingual children who receive services that are responsive to their characteristics, experiences, and specific needs. Lastly, this study used a multiple regression analysis to examine the Kindergarten Early Assessment test that has been put in place to measure the school readiness performance of bilingual children in this urban district. Specifically, the analysis included program type, language of assessment, socio-economic status and gender variables.
An Evaluation of Long-Term Air Quality Trends in North Texas using Statistical and Machine Learning Techniques
While ozone design values have decreased since 2000, the values measured in Denton Airport South (DEN), an exurban region in the northwest tip of the Dallas-Fort Worth (DFW) metroplex, remains above those measured in Dallas Hinton (DAL) and Fort Worth Northwest (FWNW), two extremely urbanized regions; in addition, all three sites remained in nonattainment of National Ambient Air Quality Standards (NAAQS) ozone despite reductions in measured NOx and CO concentrations. The region's inability to achieve ozone attainment is tied to its concentration of total non-methane organic compounds (TNMOC). The mean concentration of TNMOC measured at DAL, FWNW, and DEN between 2000 and 2018 were 67.4 ± 1.51 ppb-C, 89.31 ± 2.12 ppb-C, and 220.69 ± 10.36 ppb-C, respectively. Despite being the least urbanized site of the three, the TNMOC concentration measured at DEN was over twice as large as those measured at the other two sites. A factor-based source apportionment analysis using positive matrix factorization technique showed that natural gas was a major contributing source factor to the measured TNMOC concentrations at all three sites and the dominant source factor at DEN. Natural gas accounted for 32%, 40%, and 69% of the measured TNMOC concentration at DAL, FWNW, and DEN, respectively. The Barnett Shale region, an active shale gas region adjacent to DFW, is a massive source of unconventional TNMOC emissions in the region. Also, the ozone formation potential (OFP) of the TNMOC pool in DEN were overwhelmingly dominated by slow-reacting alkanes emitted from natural gas sources. While the air pollutant trends and characteristics of an urban airshed can be determined using long-term ambient air quality measurements, this is difficult in regions with sparse air quality monitoring. To solve the lack in spatial and temporal datasets in non-urban regions, various machine learning (ML) algorithms were used to train a computer …
The Differences in Mental Effort and Task Difficulty between Veterans and Non-Veterans in Bachelor of Applied Arts and Science Degree Programs at Texas Public Universities
This dissertation seeks to determine the differences between veteran and non-veteran students' mental effort and task difficulty within undergraduate online courses in Bachelor of Applied Arts and Sciences (BAAS) programs at three public Texas universities. The BAAS program is geared toward non-traditional students, which includes veterans. The courses are delivered in flexible formats, including online courses, face-to-face courses, and blended courses, which use a combination of online and face-to-face courses. After reviewing literature and utilizing both the cognitive theory of multimedia learning and the cognitive learning theory, a survey was conducted using undergraduate students enrolled in BAAS programs at three public Texas universities. The data was analyzed by conducting a factorial ANOVA and Pearson correlation to determine if there was a difference between veterans and non-veteran students' mental effort and task difficulty within online courses within the BAAS programs. The results indicated that that all three hypotheses failed to reject the null hypotheses that: (1) there is no difference in mental effort of students who had military service, versus those who did not have military service, (2) there is no difference in mental effort of students who had military service, versus those who did not have military service, and (3) there is no difference in the correlation between successful completion of distance learning courses of students who had military services versus those who did not have military service.
A 'Bohemian' Premiere? Smetana's "The Bartered Bride" and National Identity in 1909 New York
When Czech composer Bedřich Smetana's opera The Bartered Bride received its American premiere at the Metropolitan Opera in February 1909, New York music critics published positive reviews which displayed a great fascination with the many "Bohemian" aspects of the production. However, certain comments or language used by some critics indicate that American opinions of the Czech people were less than positive. After Czechs began immigrating to America en masse in 1848, already-established American citizens developed skewed cultural perceptions of the Czech people, established negative stereotypes, and propagated their opinions in various forms of press throughout the nation. Despite a general dislike of the Czechs, reviewers revered The Bartered Bride and praised its many authentic "Bohemian" qualities. This research explores the idea of a paradoxical cultural phenomenon in which the prejudice against Czech people did not fully cross over into the musical sphere. Instead, appreciation for Czech music and musicians may have trumped any such negative opinions and authentic Czech productions such as The Bartered Bride may have been considered a novelty in the eyes of early twentieth-century New Yorkers.
Examining the Under-Representation of Female Euphonium Players in the USA
Females make up the minority in professional euphonium playing and teaching roles in the USA. The purpose of this research is to unveil the reasons behind this imbalance and to discover potential impacts females experience as a minority in the field. Research methods included sending a questionnaire to professional female euphonium players and teachers to document the experiences of participants. A secondary purpose of this study is to further document the existence of past and present potential female euphonium role models. Through a discussion of possible origins of and reasons behind a perceived lack of female euphonium players, I am seeking ways to achieve greater parity by garnering a more comprehensive understanding of the challenges faced by female euphonium players.
Storm Water Retention Ponds: An Important Source of Aquatic Macroinvertebrate Diversity in a Semi-Arid Urban Landscape of Denton, Texas
The City of Denton, located in a semi-arid region of Texas, has over 200 manmade ponds within its city limits. Many of these ponds, located in densely populated areas, are engineered to control storm water runoff. There is a general lack of recognition of the value these waters contribute to regional biodiversity and as greenspaces. This study, conducted in Denton, is monitoring habitat variables and macroinvertebrate diversity in a series of ponds selected to represent a gradient of urban influences. The objective of this study is to identify the variables associated with the highest diversity. Using drone imagery and a meter square box sampler, the quantitative approach allowed for delineation of three habitat types and area. The macroinvertebrates where identified to the genus level which allowed for higher resolution and resulted in stronger comparisons of the communities and conditions of the ponds. Taxa richness was positively correlated to pond size and trees along shoreline and negatively associated with average depth. Overall, submerged vegetation supported highest diversity and abundance, especially genera of Chironomidae (Diptera). Conductivity was associated with urban influences and the most urban influenced pond had the lowest taxa richness, but also reduced habitat area. Results of this study conclude that these stormwater ponds benefit to the ecology of the city and provide beautiful, green spaces. If managed correctly, these systems can be incorporated into sustainable development in the future of the City of Denton.
Supportive Conditions for the Successful Development of Ninth-Grade Centers
The transition from middle school to high school can be challenging for some students. Many school districts are implementing practices to ease the transition to high school. The current study examined one school district's practices and procedures for the development and implementation of a ninth-grade center. In this study, I examined the perceptions of 12 participants (teachers, counselors, and campus and district administrators) in a suburban Texas school district with a ninth-grade center. Using a qualitative descriptive case study methodology, data were collected and analyzed from face-to-face in-depth interviews and a focus group. The findings revealed an overall positive view of ninth-grade centers and a generally favorable impression of separating ninth graders from the remainder of the high school student body, to focus specifically on ninth graders' unique and individual needs. There were some identified concerns related to communication and logistical issues between the ninth-grade center and the main high school campus. From participant feedback, effective campus leadership, providing engaging and ongoing professional learning, having a separate facility, and creating a sense of team through building strong relationships are the specific top four elements that are most effective in developing a ninth-grade center. While this study provides a practical set of recommendations for school districts to guide the development and implementation of a ninth-grade center, expanded research is necessary to confirm the long-range impact on student achievement.
Horn Concerto in E-flat Major (C41) by Antonio Rosetti: A Critical Edition
This project delivers to the scholar and performer a critical edition of a little-known horn concerto by Antonio Rosetti. Standing in contrast to performance or practical editions, critical editions demand that the editor exerts a non-trivial measure of authority over the state of the text. Performers often find this fact to be uncomfortable given the normal tendency to revere the perceived intent of the composers based upon the text that they set down. When engaging with sources, it is rarely clear what that intent is, or which of the available sources most closely represents that intent. Those available sources often disagree with one another, even those in the composer's own hand. It is vital for the editor to know, as precisely as is possible, who created the source material, when they created these sources, and why they created these sources. At that point the editor must decide which sources will best fit his or her framework for the creation of the critical edition. At that point the editor will grapple with numerous inconsistencies and ambiguities within those sources, and then use his or her own authority to fix the text of the composer's work into a single version for today's use. The Horn Concerto in E-flat Major (C41) by Rosetti presents a unique case to the editor, scholar, and performer, in that it exists in two versions that carry substantial differences in the solo part. These differences are so great that it is often difficult to consider them as representative of the same work. This edition presents both versions, as each have different original purposes, and edits them in parallel so that the performer may determine which usage is most appropriate for his or her needs.
