Access to Health Care and Rates of Mortality and Utilization for the Elderly in Rural America
The aging experience of men and women in rural America is different than that of their urban counterparts. In this study, I identified key disparities in access to health care, mortality, and utilization of health care that result from geographic location. Foundational theories are discussed to illustrate that disparities can originate from historical societal behaviors. Secondary data and literary reviews create a combined qualitative and quantitative approach to explore the rural/urban divide, concluding that the potential for increased disparities as the aging population grows is very real and rural residents remain vulnerable to a poor(er) aging experience. Recommendations for policy and practice, as well as additional research, are made to address the conclusion.
African-American Achievement in Charter Schools and the Impact of Connectedness, Alignment, Rigor, and Engagement (C.A.R.E.) on School Effectiveness: A Meta-Analysis and Systematic Review
The purpose of the study was to examine the effects of charter schools on African-American students, this study sought to determine if the practice of connectedness, alignment, rigor, and engagement (C.A.R.E.) influenced academic outcomes. The research methodology employed a meta-analysis in conjunction with a systematic review as a cross-reference and to address variables not covered in the meta-analysis. Utilizing a meta-analysis allowed for a synthesis of the existing quantitative published data to consolidate the results. This produced a specific report of achievement data for African-American students. The results revealed that regardless of region, subject, type of assessment, or school focus charter school do positively influence African-American students' academic outcomes. This study also found the practices connectedness, alignment, rigor, and engagement, the C.A.R.E. model when employed in schools improve academic outcomes, especially when combined and implemented with best practices.
Association of College and Career Readiness Indicators on Hispanic College Enrollment and Postsecondary Resiliency
This investigation was a post-hoc, quantitative analysis of secondary academic performance and participation choices of Hispanic students. Three years of longitudinal student-level data was collected to examine the likelihood of college enrollment based on college and career readiness (CCR) factors. At the time of the study, CCR was defined as qualifying exam scores, credit for at least two advanced/dual enrollment courses, or enrollment in a career and technology education (CTE) coherent sequence of courses. Research participants (N = 803) consisted solely of Hispanic high school graduates from the 2014 cohort. Frequency statistics indicate 45.5% (n = 365) attended an institute of higher education (IHE) within 2 years of high school graduation. Findings reveal Hispanic females were more likely than Hispanic males to meet CCR indicators as well as postsecondary resiliency outcomes. Analysis of chi-square tests of independence suggests a moderately strong association exists between CCR indicators and postsecondary participation among high school graduates. Differences were found in terms of gender and postsecondary enrollment, x^2(6) = 24.538, p < .001. Differences were also found in terms of type of IHE and postsecondary resiliency, x^2(3) = 34.373, p < .001. More Hispanic CCR graduates enrolled at 2-year and 4-year IHE than expected by chance. While non-CCR graduates enrolled in IHE, they were less likely to meet postsecondary resiliency outcomes. CCR graduates who initially enrolled at 2-year IHE were also less likely to persist. Furthermore, the greatest contribution to differences in resiliency existed for Hispanic CCR graduates who enroll at 4-year IHE.
The Biogeographic Distribution of Caddisflies (Insecta: Trichoptera) within the South-Central United States
Through the use of natural history records, published literature, and personal sampling (2011-2016) a total of 454 caddisfly species represented by 24 families and 93 genera were documented from the south-central United States. Two Hydroptilidae species were collected during the 2011-2016 collection efforts that are new to the region: Hydroptilia scheringi and Mayatrichia tuscaloosa. Eightteen species are endemic and 30 are considered species of concern by either federal or state agencies. The majority of each of these groups is Hydroptilidae, or microcaddisflies. Trichoptera community structure, by minimum number of species, was analysed in conjunction with large-scale geographical factors to determine which factor illustrated caddisfly community structure across the region. Physiographic provinces compared to other geographic factors analyzed best-represented caddisfly communities with a minimum of 10 or more species. Statistically, Hydrologic Unit Code 4 (HUC 4) was the most significant geographical factor but low number of samples representing this variable rendered it less representative of caddisfly community structure for the study area.
Changes in Student Borrowing at Private Not-for-Profit Four-Year Institutions in the United States
Trends in tuition and financial aid policy have increased the number of students who borrow for higher education and the aggregate debt students acquire. Most research on student borrowing over the years has analyzed the effects of borrowing and the prospects of indebtedness on individual students' choices and persistence. However, dynamics at the institutional level such as the need to ensure a stable flow of resources may accelerate or slow down student borrowing. Drawing on resource dependence theory, this study examined changes in student borrowing at private not for profit four year institutions in the US to identify trends and implications. A fixed effects regression analysis was applied to panel data from the Delta Cost project and the National Association of College and University Business Officers. Analytical focus was on the financial and enrollment characteristics of private not for profit four-year institutions, the relationship between these characteristics and student borrowing, and whether these relationships are stable or change over time. Findings revealed that the financial and enrollment characteristics of private not for profit institutions during the study period were characterized by gradual variation. The results also revealed that most of the financial characteristics were predictive of student borrowing and that these relationships vary with time. Evidence from this study cautions higher education policy makers that high tuition dependence and the attendant student loan burden may disadvantage some students. Policy makers concerned about providing equitable access to higher education to all student subpopulations should try to moderate competition among institutions and tuition rises that intensify student borrowing. Institutional practices such as tuition maximization and selective price discrimination must be moderated so that financial aid, including loans, can realize the objective of encouraging fairness and choice in higher education entry.
Chronic Homelessness and the Aging Population: Findings in a Homeless Sample from Arkansas
Understanding underlying mechanisms and pathways that lead to chronic homelessness would help develop intervention strategies that could help prevent subsequent episodes of homelessness. Quantitative data for this cross-sectional study was gathered by interviewing individuals who were homeless in the State of Arkansas, using a structured survey between 2007 and 2011. Qualitative data was gathered using semi-structured interviews between 2016 and 2018. Chi-square statistics and a multivariate logistic regression model was used to analyze the quantitative data, while phenomenological methods were used to analyze the qualitative data. Nearly half of the study participants identified themselves as being chronically homeless. Chronically homeless adults in this region were significantly more likely to be older men with no family ties, more likely to be victims of domestic violence, have higher rates of physical health problems, and have alcohol and substance abuse problems. Results from the multivariate nominal regression revealed that individuals who reported themselves as chronically homeless were more likely to be in the 50 years or older age group. In addition, study findings highlighted a dynamic interplay between three biopsychosocial risk factors for homelessness. Fostering development of inclusive sustainable communities, intergenerational relationships, and shared housing practices could help ease such social inequities and prevent problems such as chronic homelessness in older homeless adults.
A Comparison of Major Factors that Affect Hospital Formulary Decision-Making by Three Groups of Prescribers
The exponential growth in medical pharmaceuticals and related clinical trials have created a need to better understand the decision-making factors in the processes for developing hospital medication formularies. The purpose of the study was to identify, rank, and compare major factors impacting hospital formulary decision-making among three prescriber groups serving on a hospital's pharmacy and therapeutics (P&T) committee. Prescribers were selected from the University of Texas, MD Anderson Cancer Center which is a large, multi-facility, academic oncology hospital. Specifically, the prescriber groups studied were comprised of physicians, midlevel providers, and pharmacists. A self-administered online survey was disseminated to participants. Seven major hospital formulary decision-making factors were identified in the scientific literature. Study participants were asked to respond to questions about each of the hospital formulary decision-making factors and to rank the various formulary decision-making factors from the factor deemed most important to the factor deemed least important. There are five major conclusions drawn from the study including three similarities and two significant differences among the prescriber groups and factors. Similarities include: (1) the factor "pharmacy staff's evaluation of medical evidence including formulary recommendations" was ranked highest for all three prescriber groups; (2) "evaluation of medications by expert physicians" was ranked second for physicians and midlevel providers while pharmacists ranked it third; and (3) the factor, "financial impact of the treatment to the patient" was fifth in terms of hospital formulary decision-making statement and ranking by all three prescriber groups. Two significant differences include: (1) for the hospital-formulary decision making statement, "I consider the number of patients affected by adding, removing, or modifying a drug on the formulary when making hospital medication formulary decisions," midlevel providers considered this factor of significantly greater importance than did physicians; and (2) for the ranked hospital formulary decision-making factor, "financial impact of treatment to the …
A Cross-Cultural Study of Adult Attachment, Social Self-Efficacy, Familismo, and Psychological Wellbeing
Although Latinos are the largest minority group in the country, research examining how different psychological and cultural variables affect Latino individuals' wellbeing is disproportionately developed and cross-cultural comparison studies are particularly scarce. To address these issues, this dissertation research examined cross-cultural adult attachment-social self-efficacy-psychosocial wellbeing conceptual mediational model while investigating the moderator effects of country membership and familismo on the proposed mediational model using a cross-cultural sample of Mexican and Mexican-American university students. A total of 595 participants, including 360 Mexican students from Mexico and 235 Mexican-American students from the United States completed the research questionnaires. Results indicated that social self-efficacy was a significant mediator for the effects of insecure attachment on life satisfaction and conflict resolution in both cultural groups and for the links between attachment insecurity and depressive symptoms in the Mexican-American group. Additionally, moderated mediation analyses showed that country membership was a significant moderator for the links between attachment avoidance and social self-efficacy when life satisfaction, conflict resolution style, and depressive symptoms were the dependent variables, as well as for the direct link between attachment anxiety and physical health symptoms. Familismo was also found to be a significant moderator for the direct effects of attachment anxiety on physical health symptoms and life satisfaction in both groups. Findings are discussed from the attachment and cross-cultural perspectives. Counseling implications, limitations, and future research directions are offered.
Demand and Supply Explanation: Nonprofit Size in Homeless Service Area
This study explores the demand and supply oriented factors that may contribute to the size of nonprofit organizations in the U.S. communities. This research tests demand theory, which indicated that nonprofit organizations grow more in communities where large service demand exists and when there is a service gap between community demand and government service supply. On the other hand, supply theories contend that nonprofit organizations are prevalent where a community carries the supply of human capital and financial resources and these supply of human and economic capital will mobilize nonprofit organizations to fulfill civic duties. For the scientific test of demand and supply theories, this study employs hierarchical linear model (HLM) and develops a longitudinal data set from multiple sources such as Department of Housing and Urban Development and National Charitable Center for Statistics, and Census. The proposed model analyzes how demand and supply indicators explain homeless serving nonprofit organizations size. The size of homeless service nonprofit was measured by three indicators: number of nonprofits, revenue of nonprofits and number of shelter beds. The findings of HLM analyses confirmed some of demand and supply factors that contribute homeless service nonprofit size. The communities with higher level of chronic homeless population have more nonprofit organizations when we control community size. Also, we found the communities with a greater number of educated individuals are more likely to invest in nonprofit organizations. And it was noteworthy that the higher education institution was a positive supply factor for the nonprofit size in our communities.
The Double Down: The Autoethnography of Navigating as Black American Male Instructing Preservice Teachers Methods of Teaching Social Studies
This inquiry is an autoethnography of my experiences as a Black American male serving as a methods of social studies instructor to preservice teachers. Although some may deem this study as subjective, I have embraced that designation to provide insider information to others that face intersectionality and to inform institutional practices in teacher education programs.
Drug-Related Violence and Party Behavior: The Case of Candidate Selection in Mexico
This dissertation examines how parties respond and adapt their behavior to political violence. Building a theoretical argument about strategic party behavior and party capture, I address the following questions: How do parties select and recruit their candidates in regions with high levels of violence and the pervasive presence of VNAs? Do parties respond to violence by selecting certain types of candidates who are more capable of fighting these organizations? Do parties react differently at different levels of government? And finally, how do VNSAs capture political selection across at different levels of government? I argue that in regions where there is high "uncertainty," candidate selection becomes highly important for both party leaders and DTOs. Second, I argue that as violence increases and the number of DTOs also, criminal organizations, as risk-averse actors, will capture candidate selection. I posit that as violence increases, there is a greater likelihood that candidates will have criminal connections. To test my theory, I use the case of Mexico. Violence in Mexico and the presence of criminal organizations across the country has experienced a great deal of variation since the 1990s. In Chapter 2, I find that violence affects the gubernatorial candidate selection of the PRI, PAN and PRD. In high violence states, parties select gubernatorial candidates with long experience in subnational politics compared to other types of experiences. In chapter 3, however, I find that at the municipal level not all the parties respond equally to violence. As a municipality becomes more violent, the PRI and PAN party leaders are more likely to select mayoral candidates who were either state or federal deputies or candidates who were both. In contrast, the PRD is likely to recruit state deputies as a function of violence, but not national deputies or candidates who were deputies at both the state …
Educator Perceptions of Forces Influencing Implementation of a Statewide Writing Portfolio Assessment
Leaders of the 84th Texas Legislature drafted and ratified HB 1164 (2015), prompting the Texas Education Agency to pilot a portfolio assessment option for assessing student writing growth and proficiency. The purpose of this study was to identify the perceptions, characterize the experiences, and identify the forces that influenced initial implementation of the statewide writing pilot. Through interviews with district leaders and the collection of open-ended questionnaires from participating educators, a collective case study method was conducted and allowed for analysis of cross-case themes. The identification of restraining and driving forces affecting implementation of the statewide pilot program provided insight into considerations for next steps in the evaluation of student writing achievement and growth. Three primary perceptions emerged as restraining forces influencing implementation: influences of inadequate funding, inconsistencies of implementation, and navigation of multiple assessment systems. Six primary themes related to driving forces influencing implementation were identified: using sociocultural and authentic methods, engaging in reflective practices, increasing volume and variety of writing opportunities, assessing student growth, aligning methods of instruction and assessment, and reducing stress for students. Effective professional development, dependent upon funding and staffing allocations; two-way channels of communication for participant reflection and feedback; and effective assessment structures must be aligned with the purpose and goals of a student-centered assessment system, which requires collaborative conversations between policy makers, state-level decision makers, and educators.
Effects of Cultural Intelligence and Social Support on Adjustment of International Students
The purpose of this study was to investigate direct and interaction effects of cultural intelligence and social support on the adjustment of international students to U.S. higher education. Hierarchical multiple regression analyses were conducted to test (a) if cultural intelligence was a predictor for adjustment of international students to U.S. higher education; (b) if social support was a predictor for adjustment of international students to U.S. higher education; and (c) if there was an interaction effect between cultural intelligence and social support on international students' adjustment to U.S. higher education. The participants included 262 international students from a southwestern university. The results found only social support from the university was a significant predictor of international students' adjustment. There was no interaction effect between cultural intelligence and social support from any sources on international students' adjustment.
Effects of Deepwater Horizon Crude Oil on Visual Function in Teleost Fishes
The Deepwater Horizon oil spill released millions of barrels of oil into the Gulf of Mexico, impacting economically and ecologically important fishes. Polycyclic aromatic hydrocarbons (PAHs) present in the oil have been shown to cause developmental impairments in early life stage fishes, such as morphological and behavioral changes related to eye formation and visual processing following PAH exposure. Prior research reported reduced eye growth in open water, pelagic species, as well as reduced photoreceptor-specific transcription factors associated with eye development following exposure to crude oil. Though changes in transcriptomic-level pathways associated with vision and visual processing have been reported, it has yet to be determined how these changes relate to physiological or behavioral-level effects in fish. Therefore, the present studies evaluated the effect of weathered crude oil on eye development and visual function in mahi-mahi, red drum, sheepshead minnow, and zebrafish larvae. Fish were assessed through several visually-mediated behavioral assays, analyzed histologically and immunohistologically, along with subsequent transcriptomic analyses and associated gene expression changes. Larvae exposed to crude oil experienced significantly reduced abilities to exhibit optomotor or optokinetic responses relative to controls, with associated reductions in retinal development. Furthermore, genes associated with eye development and phototransduction were downregulated, with subsequent decreases in the immunofluorescence of neurological connections within the retina and a choroid-specific increase in apoptotic activity. We related oil-induced transcriptomic-level effects to morphological, physiological, and behavioral-level impairments in larval teleost fishes.
The Effects of the $0.50-Debt Test on Fast Growth Texas School Districts: A Case Study of Three Districts
A three-district case study was conducted to determine the effects of the 50-cent debt test on fast-growth Texas school districts. The 50-cent debt test for Texas schools came into existence as part of Senate Bill 351 in 1991. Prior to the passing of Senate Bill 351, districts in Texas were limited to issuing 10% of their assessed valuation. Of the 75 school districts that currently meet the criteria to be considered a fast-growth district, 15 of the districts had an Interest and Sinking tax rate of $0.50 in 2014. Also, 33 of the 75 districts had an Interest and Sinking tax rate of $0.40 or higher in 2014. The 50-cent cap on the interest and sinking fund tax rate for districts is arbitrary and inefficient. The limit does not take into account a district's enrollment growth or the wishes of local taxpayers who might vote to authorize debt to build additional facilities or a higher tax rate to pay down debt sooner. Over the past 20 years, Texas voters have approved $96.7 billion of the $118.4 billion resulting in over 81% of funding sought for facilities being approved. The issuance of the approved bond authorization by these voters is governed by the Texas Attorney General's Office, and local districts must pass the 50-cent test by statute. This study examined the impact the 50-cent test has had on three districts through interviews with district staff, and by analyzing and comparing enrollment and various financial data. Specifically, property values, bond types and terms, as well as project delays and operating budgets were assessed.
Empowering U.S. Marshallese Students to Engagement and Active Participation in Learning
The U.S. Marshallese population is one of the fastest growing Pacific Islander populations in the United States. The purpose of this study was to identify how U.S. Marshallese students could be empowered and engaged in their learning through clearly identified indicators that educators could apply within their classrooms and schools. The indicators have been established on a historical, cultural, and linked perceptions of student learning as identified by U.S. Marshallese students and teachers. Pacific Islanders consisted of a variety of populations with varying cultures and ethnic diversity. This study has been conducted using a postpositivism worldview, Marshallese migration is not a limited phenomenon of displacement, but a migratory change that must be embraced by communities and educators. Educators must understand how to empower and engage U.S. Marshallese students in their learning. This study was designed utilizing an interpretative descriptive naturalistic ethnography qualitative research design with middle school students and teachers to gather qualitative data from U.S. Marshallese students that will lead to a contextual understanding of empowering and engaging U.S. Marshallese students in their learning. The findings of this qualitative research study can be applied by educators to empower and engage U.S. Marshallese students in their learning on a daily basis in schools and classrooms. Culture understanding, positive relationship building, and the design of culturally connected intrinsically student motivated learning activities is the foundation and critical component of empowering and engaging U.S. Marshallese students in school and classrooms for improved student learning.
Exploration of Information Sharing Structures within Makerspaces: A Mixed Methods Case Study of Dallas Makerspace and Its Users
Makerspaces are a popular, new concept being implemented in public, academic, and school libraries, and as stand-alone spaces. The literature reflects the newness of the topic with a limited number of articles and studies and even less about the users of makerspaces themselves. This study explored information sharing behaviors in the Dallas Makerspace as an informal learning environment and described their preferred method of information transfer from one member to another. It employed a mixed methods methodology using surveys, interviews and observations. The study identified how the rules and policies in place at the makerspace influence the information seeking process and how the Dallas Makerspace exchanges information effectively. Dallas Makerspace is one of the largest non-profit work groups in its size, and this research study answers how information is exchanged in an informal environment.
An Exploratory Mixed Method Study of Gender and Sexual Minority Health in Dallas: A Needs Assessment
Gender and sexual minorities (GSM) experience considerably worse health outcomes than heterosexual and cisgender people, yet no comprehensive understanding of GSM health exists due to a dearth of research. GSM leaders in Dallas expressed need for a community needs assessment of GSM health. In response to this call, the Center for Psychosocial Health Research conducted a needs assessment of gender and sexual minority health in Dallas (35 interviews, 6 focus groups). Competency was one area highlighted and shared across existing research. Thus, the current study explored how competency impacts gender and sexual minorities' experience of health care in Dallas. We utilized a consensual qualitative research approach to analyze competency-related contents. The meaning and implications of emerging core ideas were explored. These findings were also used to develop a survey instrument.
Framing the DREAM Act: An Analysis of Congressional Speeches
Initially proposed in 2001, the Development, Relief, and Education for Alien Minors Act (DREAM Act) continues to be relevant after nearly 20 years of debate. The year 2010 was significant because there seemed to be some possibility of passage. This study investigated the ways in which the DREAM Act discourse was framed that year by supporters and opponents. Selected Congressional speeches of three supporters and three opponents were analyzed using the approach to frame analysis developed by Schön and Rein. Accordingly, attention went to each individual's metacultural frame (i.e., culturally shared beliefs), policy frame (i.e., identification of problem and presentation of possible solution), and rhetorical frame (i.e., means of persuading the audience). Attention also went to the shared framing among supporters and the shared framing among opponents as well as differences in framing across the two groups. Although speakers varied in framing the issue, there were commonalities within groups and contrasts between groups. For supporters, the metacultural frame emphasized equity/equal opportunity, fairness, and rule of law; for opponents, the metacultural frame stressed rule of law, patriotism, and national security. For supporters, the policy frame underscored unfairness as the problem and the DREAM Act as the solution; for opponents, the policy frame emphasized the DREAM Act as the problem and defeating the DREAM Act as the solution. Rhetorical frames also differed, with the supporters making much use of testimonial examples and the opponents making much use of hyperbole. The study illustrates (1) how the same named values and beliefs can have dramatically different interpretations in metacultural framing, as were the case for rule of law and American dream in this discourse; (2) how the crux of an issue and its intractability can be seen by looking at how the problem is posed and how the solution is argued, and (3) how …
The Hoboken War Bride: A Novel
The Hoboken War Bride is a work of historical fiction set in Hoboken, New Jersey during World War II. A young soldier named Daniel and an aspiring actress named Hildy marry days after meeting, though the marriage is doomed to fail. This young couple is not compatible. Daniel ships out to basic training the day after their hasty marriage, leaving Hildy behind with his family, the Anellos, who she quickly becomes attached to. Hildy is exposed to family in a way she had never lived with her own, embracing them even though she doubts she'll ever have a future with Daniel. When Daniel returns after the end of the war, the young couple try to make their marriage work, but it fails almost immediately. Both Hildy and Daniel struggle to pick themselves up after their divorce, finding themselves making choices they never thought they would when they were younger.
The Identification and Participation of Latino Students in Advanced Mathematics Courses
Using a phenomenological approach, this qualitative study examined the perspectives of Latino parents and their involvement in the decision of their child to enroll in an advanced mathematics course in sixth grade. Since enrollment in Algebra I in high school is said to be a strong predictor of college attainment and with the growing number of Latino students across the nation, this study has the potential to help district and campus leaders establish whole-school systems for communicating with Latino parents to encourage their children to enroll in advanced mathematics courses at earlier grades. Participants in this study included four sixth-grade students enrolled in an advanced mathematics course, four enrolled in regular mathematics, their mother or father, two mathematics teachers, a school counselor, and two district administrators. Data analyzed included audio recordings of semi-structured interviews of each of the participants. The findings suggested that the district has proactively developed a systematic process of creating that includes six data points to create a student profile of students that will do well in advanced mathematics. This process is helping the district close the gap between total Latino school enrollment and the enrollment of Latino students in advanced mathematics. The findings also suggested that specific communication with parents about the importance of enrollment trajectories might influence the enrollment of students into advanced mathematics courses at earlier grades.
The Impact of Teacher Professional Development on Student Achievement at a North Texas High School as Measured by End-of-Course Assessments in Algebra I and English Language Arts
The purpose of this study determined if a significant relationship existed between the amount of professional development that teachers participated in and the impact on the classroom instruction that followed. The goal was to study the effect that this had on student achievement in the State of Texas Assessment of Academic Readiness (STAAR) for English 1 and Algebra 1 for students at a large north Texas high school. Testing years for the study included the school years 2013-14, 2014-15, and 2015-16. Additional variables included the work in three areas of teacher professional development over the three-year period. Fourteen teachers, in two subjects, were studied in their implementation of classroom instruction. Particular attention was given to the instructional changes, and the number of hours of professional development in the areas of instruction, technology, and differentiation. Teachers were given opportunities to participate in 18 hours of professional development in all three areas in each of the three years. Teachers were then asked to incorporate the work that they completed each year into their day to day classroom instruction. The goal of the implementation of the professional development in addition to the curricular specifics regarding instruction of state standards was expected to produce increased state scale score marks for the students in the classes. Results of the study indicated success for students in the area of English 1 end-of-course assessment. From the beginning of the study, where student success rates in English state assessment was calculated at 47% overall passing rate, to the completion of the study, where student success was charted at 70% overall passing rate, significant changes were noted. In addition to the improvements made in English I, there were also significant changes made in the approaches to the Algebra 1 assessment. Classroom instructional practices were noted as much improved, and …
Influences on Latino Males' Enrollment in Four-Year Colleges
The purpose of this study was to explore characteristics that influence Latino male students' enrollment in four-year colleges. This study utilized a mixed-methods approach and acquired information specifically pertaining to the high school Latino male population. Participants for the study included Latino male high school students in Grades 9-12, parents of Latino male high school students in Grades 9-12, and counselors of high school students in Grades 9-12. The study was conducted across two campuses. Data for student and parent participants were obtained through an online survey questionnaire and counselor data was obtained through face-to-face semi-structured interviews. The results of this study reveal that there are influential characteristics that contribute to Latino males' potential enrollment in college. Of the data obtained from student participants, 70.2% of participants on Campus 1 and 90.5% of participants on Campus 2 planned on attending college. Responses from parent surveys found that 85.8% of parents had expectations for their Latino male student to attend college. Through the semi-structured focus group interviews, it was found that the school district and campuses in which the study was conducted had several procedures or processes in place to positively encourage Latino male student enrollment in four-year colleges. Results of this study provide a better understanding and insight on characteristics that influence the high school Latino male student in Grades 9-12 to enroll in college.
An Investigation of Paramedical Vocational Interest and Choice for Men of Color in Texas Community Colleges
Although the recent annual growth rate in the US paramedic field has been 4%, Latino and African American men have been significantly underrepresented in the field compared to their proportion in the US population at large. This problem threatens both the quality and quantity of available emergency health care. The purpose of this study was to describe how men of color (MOC) in community college paramedical programs experienced their awareness, interest, and proactive choice of paramedicine as a course of study. Using a qualitative phenomenological approach and social cognitive career theory as a theoretical framework, I interviewed 23 MOC enrolled during one semester across three community college paramedical programs in the southwestern US: 9 Latino and 14 African American, aged 18-29 with mean age 22 years. The focus of the interviews was the participants' lived experiences at various career points, as well as the enablers and disablers they had encountered. I identified three primary themes for possible use in enhancing recruitment of MOC to the paramedic field: strategic use of new digital media, promotion of the vocation's quasi-familial characteristics, and augmentation of neighborhood-based outreach. Identified areas for further research included recruitment dynamics of female paramedics, MOC persistence issues, and MOC job satisfaction assessments.
Knowledge, Attitudes and Practices of Teachers on the Use of Technology Applications with Children: A Survey of PK-5 Teachers in a South Texas Region
This quantitative methods study explored the knowledge, attitudes and practices of PK-5 teachers on the use of technology applications in the classroom. The Texas State Board of Education has set in place standards for technology applications that require the use of technology applications across all grades. Likewise, the American Academy of Pediatrics (AAP) published new guidelines on the use of technology by children. However, it is the responsibility of teachers to implement and embed these standards, while also paying attention to the recommendations of the AAP. I developed a survey that provided demographic information, and included 12 items to measure the knowledge, attitudes and practices of teachers of technology applications in the classroom. Participants included 251 PK-5 teachers from three different districts in a South Texas region. Multiple regressions were conducted for each of the constructs produced by a factor analysis. Knowledge and attitudes presented no statistically significant results from individual teacher characteristics, but there were statistically significant differences on attitudes by districts. The regression analysis for practice reported a statistically significant difference between teachers that held a master's degree and those who did not. I conclude that technology applications implementation in the PK-5 classrooms is still developing and evolving, but there is still no consistency across districts, and further research in this matter is still needed.
Leaving the Classroom: A Multiple Case Study on the Experiences of Black Women who Transitioned from Teaching to a Non-Teaching Role
This qualitative multiple case study aims to describe the experiences of two Black women who chose to leave the classroom and transition to other roles within the field of education. Using metaphorical analysis, this study employed the four-capital theoretical framework. This framework connects human capital, structural capital, social capital, and positive psychological capital as factors related to teacher attrition and retention. This study illustrates how the participants' experiences fit into the four-capital theoretical framework and highlights the metaphors the participants use to describe their transition. The researcher conducted two semi-structured open-ended interviews in which the participants were asked to describe their experiences in the classroom as well as their experiences in their new positions. The researcher analyzed the metaphors used by the participants and categorized their responses based on the four capitals. The identified metaphors offered a vivid description of the participants' experiences. The results indicated that although the experiences of the participants are similar to those found throughout the literature, the four-capital theory helps describe their experiences more holistically. Rather than having isolated reasons for leaving the classroom, the attrition of the participants can be explained by examining the interconnectedness of the various capitals. These findings suggest that teacher retention and attrition be studied by looking at a variety of causes as opposed to isolated factors.
A Legal Analysis of Litigation against Louisiana Educators and School Districts, Before and After the Louisiana Governmental Claims Act
This dissertation analyzed court decisions in injuries on school grounds cases under the Louisiana Governmental Claims Act. The question addressed was: How have the Louisiana courts interpreted the Louisiana Governmental Claims Act in litigation against Louisiana school districts and their employees? The intent of this study was to show how Louisiana's legal system has evolved, and how that evolution affected tort cases involving school boards and school board employees. Doctrinal legal research was the methodology used to answer the research question. To limit the number of cases analyzed, this study only focused on tort claims involving injury on school property. In order to gain a broad perspective, tort claims cases filed prior to the 1974 Louisiana Constitution, cases filed after the 1974 Louisiana Constitution, and cases filed after the 1995 Louisiana Liability Limits Amendment, and the Louisiana Governmental Claims Act of 1996 were analyzed. By analyzing the tort claims brought against Louisiana school districts and employees during the various time-periods, it was clear to see how the case rulings reflected the frequent changes of the Louisiana Constitution and its' laws. In the end, the state continued to control who could sue them and how much they would pay in damages.
Long-Term Citizen Science Water Monitoring Data: An Exploration of Accuracy over Space and Time
The Texas Stream Team (TST) is one of an increasing number of citizen science water monitoring programs throughout the US which have been continuously collecting surface water quality data under quality assurance protocols for decades. Volunteer monitoring efforts have generated monitoring datasets that are long-term, continuous, and cover a large geographic area - characteristics shown to be valuable for scientists and professional agencies. However, citizen science data has been of limited use to researchers due to concerns about the accuracy of data collected by volunteers, and the decades of water quality monitoring data collected by TST volunteers is not widely used, if at all. A growing body of studies have attempted to address accuracy concerns by comparing volunteer data to professional data, but this has rarely been done with large-scale, existing datasets like those collected by TST. This study assesses the accuracy of the volunteer water quality data collected across the state of Texas by the TST citizen science program between 1992-2017 by comparing it to professional data from corresponding stations during the same time period, as well as comparing existing and experimental data from a local TST partner agency. The results indicate that even large-scale, existing volunteer and professional data with unpaired samples that may have been taken months apart can show statewide agreement of 80% for all parameters (DO = 77%, pH = 79%, conductivity = 85%) over the 38 years of sampling included in the analyses, across all locations. The local case study using paired datasets for which a greater number of factors were controlled for show an even higher agreement between volunteers and professionals (DO = 91%, pH = 87%, conductivity = 100%) and show no significant difference between experimental and existing sampling data. The results from this study indicate that TST has been collecting water …
Meaning in Life and Psychological Wellness among Latino Immigrants: Role of Attachment, Belongingness, and Hope
Guided by attachment theory and principles of positive psychology, a conceptual model was developed depicting the direct and indirect effects of attachment insecurity, state hope, belongingness, and meaning in life on wellness indicators (i.e., life satisfaction, physical health, and depression) of first generation Latino immigrants in the U.S. Specifically, the present study proposed that the effects of attachment insecurity on Latino immigrants' wellness would be mediated by two tiers of factors. The first tier consisted of state hope (i.e., general state hope, spiritual state hope, mastery state hope) and sense of belonging (i.e., general belongingness; connectedness with mainstream/ethnic community), which represented individual-level and relational factors, respectively, salient in Latino culture. Greater attachment insecurity was hypothesized to contribute to a compromised MIL and poorer wellness by decreasing state hope and sense of belongingness. A total of 352 first-generation Latino immigrants from Texas participated in this study. The exploratory factor analysis on the Experiences in Close Relationships Scale revealed a two-factor factor structure that is different from the two factors of adult attachment typically found with American samples (i.e., anxiety and avoidance). The emerged two factors represent anxious-distancing attachment and comfort-seeking attachment. Results from structural equation modeling analysis showed adequate model fit with the data. The final model indicated that the effects of comfort-seeking attachment on wellness were fully mediated by two layers of mediators (belongingness and state hope as the first layer and meaning in life as the second layer). In addition, the effect of anxious-distancing attachment on wellness was fully mediated by belongingness and meaning in life but not through state hope. Bootstrap methods were used to assess the significance magnitude of these indirect effects. Comfort-seeking attachment explained 13% of the variance in state hope and both attachment variables explained 36% of the variance in sense of belongingness. Anxious-distancing attachment, …

This dissertation examines the effects of micro-level inequality on political preferences and voting behavior.
The Population Genetic Structure of Quadrula aurea (Bivalvia: Unionidae), A Threatened Freshwater Mussel in Central Texas
The anthropogenic alteration of riverine ecosystems has led to declines in the abundance and diversity of freshwater mussels (Bivalvia: Unionoida) worldwide. Central Texas is home to a diverse freshwater mussel fauna including three candidates for federal listing under the Endangered Species Act. Surveys conducted over the last few decades suggest many of the endemic freshwater mussel species in Texas exist in small isolated populations that may be vulnerable to the deleterious effects of genetic diversity loss. Microsatellite primers from two closely related species were used to identify a set of genetic markers that functioned in the Golden Orb (Quadrula aurea). Microsatellite markers were then applied to document the population genetic structure of Q. aurea within and among three connected river drainages in southeastern Texas. Gene flow within existing Q. aurea populations appears high indicating little potential for genetic issues stemming from isolation and inbreeding. Two weakly divergent admixed populations were identified occupying the San Antonio and Guadalupe/San Marcos rivers. Population genetic structure was related to river basin affiliation, but results for environmental factors were unresolved. Current effective population size estimates are large for the Guadalupe/San Marcos drainage and moderately large for the San Antonio drainage and there is no clear genetic evidence of contemporary population declines. Transport in the glochidial phase by a highly mobile host fish, the channel catfish (Ictalurus punctatus), may provide a mechanism for maintaining connectivity among spatially discrete mussel beds and deserves further study. Information on the occurrence and habitat associations of Q. aurea and two other threatened freshwater mussel species was documented. Quantification of the population genetic structure for Q. aurea provides important information needed for the management of this species, a baseline for understanding future changes, and insight into the factors that shape the population genetic structure of other threatened unionids in Texas.
Portraits of Young Artists: Artworlds, In/Equity, and Dis/Identification in Post-Katrina New Orleans
Using portraiture methodology and social practice theory, this study examined the identity work of young people engaged in a teen arts internship program at a contemporary arts center in post-Katrina New Orleans. This research asked four interrelated questions. Through the lens of a teen arts internship at a contemporary arts center in post-Katrina New Orleans, 1) How do contextual figured worlds influence artist identity work? 2) How does artist identity work manifest through personal narratives? 3) How does artist identity work manifest in activities? 4) What are the consequences of artist identity work? The findings of the study highlight how sociocultural factors influence dis/identification with the visual arts in young people and provoke considerations of in/equity in the arts.
Presence of Instruction regarding Technology Leadership in Texas University Principal Preparation Programs: An Exploratory Study
This study investigated the presence of technology leadership components in Texas principal preparation programs. Programmatic and course information of principal preparation programs holding accreditation with Texas Education Agency were analyzed to determine presence of technology leadership instruction. Results were compared with Shrum et al.'s 2011 research, and showed a slight increase in presence. This study also examined possible differences in technology leadership components based on if the course was delivered online, face-to-face, or blended. Results showed a stronger presence of technology leadership in online courses. Additionally, the degree of alignment of technology leadership components being taught in principal preparation programs in Texas with the International Society for Technology in Education was explored. Results showed a positive correlation between technology leadership components instruction with the International Society for Technology in Education.
Reclaiming Female Virtue: Social Hygiene, Venereal Disease and Texas Reclamation Centers during World War I
During the Progressive Era in the United States, social hygiene reformers underwent a fundamental change in their stance toward women accused of prostitution or promiscuous behavior. Rather than viewing such women as unfortunate victims of circumstance who were worthy of compassion, many Progressives deemed them as predatory villains who instead deserved incarceration, forced rehabilitation, and non-consenting medical interference. Texas, due to the many military bases within its borders, became a key battleground in this moral crusade against women as the carriers and proliferators of VD. "Promiscuous" women were seen as not only dangerous to the soldiers but also as a threat to the nation's security, creating an environment that led Texas Progressives to suppress women's civil liberties in the name of protecting soldiers. The catalyst for this change in attitude was World War I. The Great War brought to the forefront an unpleasant reality facing a significant percentage of America's fighting men: venereal disease. While combating sexually transmitted diseases was a serious medical and manpower concern for the military in the era before penicillin, the sole focus on women as the carriers and proliferators of VD led to a nationwide campaign against the "social evil" that demonized women and led to the suspension of thousands of women's habeas corpus rights. This dissertation examines how the twin crusades of Progressivism and the War to End All Wars created conditions in Texas that for many women meant appalling repression rather than progress toward the enjoyment of greater equality.
The Relationship among Select School Variables and 8th Grade African American Male Academic Achievement
This study was designed to investigate the correlational relationship between four school elements listed on the Texas Academic Progress Report (TAPR) and the academic achievement of 8th grade African American male students. Data for this study was provided from the Texas Education Agency's (TEA) Office for Public Information Requests. The study included four independent variables: percent of socioeconomically disadvantaged students, average years of teachers' experience, attendance rate and average class size in mathematics. The dependent variable was the 8th grade African American males' performance on the mathematics STAAR exam. The study examined scores from the mathematics STAAR exam for the years 2012-2014. The sample population included 1,540 schools and 47,169 individual test results. The results of the correlational analysis indicate that none of the independent variables were correlated to each other, but each of the independent variables had a statistically significant correlation with the dependent variable at the p < .05 level. The study also sought to explore the variance in academic achievement that could be explained by the four independent variables when used as a model. The results of the simple multiple regression suggest that not only were the results statistically significant at the p < .01 level, but the model explained 32.4% of the variance in 8th grade African American males' performance on the STAAR mathematics exam in the years 2012-2014.
Relationships between Job Satisfaction, Work Engagement, and Turnover Intention of Health Science Teachers
The purpose of this research was to investigate the relationships between job satisfaction, work engagement, and turnover intention of health science teachers in the state of Texas. The healthcare profession is one of the largest growing occupations in the U.S. nationwide. The job growth outlook for healthcare professionals is projected to be on average 34% between 2014 and 2024. Despite the growing healthcare job categories, there is a shortage of healthcare professionals in the U.S. This study addressed the shortage of health science teachers in secondary education. Considering the importance of healthcare, especially with an aging U.S. population, it is critical to study the impact of work engagement and job satisfaction on teacher intent to leave the health science teaching profession. Through a correlational survey research design it was found that job satisfaction and work engagement are negatively related to turnover intention. Hierarchical regression analysis indicated that job satisfaction accounted for 39.6% of the variation in turnover intention. Findings also showed that work engagement did not moderate the relationship between job satisfaction and turnover intention. Implications for research and practice are discussed and conclusions are provided.
Response to Intervention (RTI) and Promising Practices: What Works at the Secondary Level
The primary focus of RtI has been at the elementary school level. However, over the past few years there has been a shift, and RtI has been expanding to secondary schools. Through this expansion, it is unclear if RtI has been effectively implemented at the secondary level. The ultimate goal for any school implementing change is institutionalization or sustainability. Therefore, this qualitative case study examined the institutionalization or sustainability of RtI systems in one high school. This study was designed to deepen the understanding of secondary RtI and to add to the literature on RtI at the secondary level. The purpose was to understand how one secondary school addressed the complexity and uniqueness of the secondary environment while sustaining RtI practices. The participants in this study shared several research-based practices that they believed assisted struggling students to become academically successful. The findings regarding RtI practices and implementation were supported by researchers whose works were analyzed in the literature review. The study concluded that understanding the phases of change, the three major forces which influenced change and a clear, well thought out plan are vital components to success.
State Created Danger and Chronic Traumatic Encephalopathy in Texas Schools: A Legal Examination
The recent breakthroughs in the research of brain trauma as it relates to athletics has revealed never before seen damage linked with football participation. Known as chronic traumatic encephalopathy (CTE), it is caused by activities inherent to the sport of football. School sponsored football has been granted immunity through case law and legislation in Texas. Recent research however indicates a different type of injury than those that school districts have been protected of liability from. This will provide a challenge to the immunity school districts have enjoyed regarding football. One route to abrogation of immunity is the state created danger provision established by the Supreme Court. The Fifth Circuit Court whose jurisdiction includes Texas has yet to officially adopt the state created danger theory. This research examined legal precedent to determine the challenge CTE may present the various layers of immunity surrounding school sponsored football in Texas.
Survey of Texas Secondary Transition and Employment Designees' Use of Evidence-Based Practices
The role of transition providers' knowledge of evidence-based practices (EBPs) in secondary transition can only be understood in the context of the dismal post-secondary outcomes of students with disabilities (SWD) and the need for bridging the research-to-practice gap among secondary transition practitioners. A sample of 1,163 Texas Employment Designees (TEDs) were surveyed about their knowledge of secondary transition EBPs. The study examined the psychometric properties and theoretical factor structure fit of a modified version of the Mazzotti and Plotner's Use of Secondary Transition EBPs survey and identified significant effects of TEDs' characteristics on their capacity for implementing secondary transition EBPs (F(9, 110) = 2.16, p = 0.03). Psychometric validation of the instrument indicated overall reliability and internal consistency of the modified instrument in measuring both knowledge and use of EBPs in support and direct provision of transition services (Cronbach's alpha of 0.99). Principal components analysis (PCA) and exploratory factor analysis (EFA) returned a simple one-factor structure. A composite score was developed for the single factor of "capacity", and a subsequent analysis was conducted to determine a relationship between the demographic factors and the overall capacity scores of respondents (n = 198). Study limitations and need for further research are discussed.
Urban Elementary School Students' Conception of Learning: A Phenomenographic Mapping of Variation
For decades, urban public schools have been plagued by systemic and structural challenges that continue today. Scholars, policymakers, and the general public have pointed to problems of learning in urban schools and to low expectations for urban students' learning, but little attention has been given to how urban students themselves conceptualize learning. This study sought to fill the void by asking a group of urban students about their views of learning. A phenomenographic approach was employed to examine the qualitatively different ways in which 20 urban elementary fifth-grade students expressed their conceptions of learning and of their learning approaches. Consistent with phenomenography, the study was intended to understand the collective expressions of individuals' conceptions regarding a phenomenon, and emphasis was on the mapping of variation across the conceptions. Semi-structured interviews with open-ended questions, conducted individually, elicited the students' conceptions of the meaning of learning and their learning approaches. In a "search for meaning" approach, analyses were based on students' transcribed responses forming a pool of quotations. These quotations were divided first into "what" and "how" categories—"what" is learning and "how" does learning occur—and then into subcategories. The results were a set of categories organized in a two-level hierarchy. The three "what" conceptions were as follows: learning as increasing knowledge, learning as growing as a person, and learning as applying knowledge. The three "how" conceptions were the following: learning by persevering, learning by using active learning strategies, and learning by participating in social interactions. These conceptions comprised an outcome space representing the six different ways that these urban school students expressed their conceptions of learning inside and outside of school contexts. Whereas much attention in the educational literature has been directed to teachers setting high expectations for urban students, students in this study seemed to be setting high expectations for themselves, …
Use of Digital Fabrication Tools and Curriculum with Gifted Students in Rural Middle Schools
This study focuses on the use of American Invention Kits from the Smithsonian Institute in conjunction with a 3D printer. In conjunction with a large dataset from a study funded by the National Science Foundation (NSF), this innovative research focuses on the effect the digital fabrication curriculum unit has on gifted and talented students' knowledge and affinity toward the fields of science, technology, engineering, and mathematics (STEM). Students from two rural middle schools in north-central Texas (N = 190) took part in this quantitative study; the students were divided among four subgroups: gifted-contrast (n = 12), gifted-treatment (n = 8), nongifted-contrast (n = 76), and nongifted-treatment (n = 94). The surveys utilized include the STEM Semantics Survey, TIMSS-Limited, and a knowledge assessment for the specific curriculum unit focused on the solenoid. The STEM Semantics Survey is divided into five subsets. Thirty-two separate one-way repeated measures ANOVAs were performed across the surveys and subgroups. Statistically significant results were found on four comparisons. This research holds implications in the areas of advocating for gifted education, collecting field data, utilizing large datasets, and understanding rural schools.
Vietnamese Students' Translanguaging in a Bilingual Context: Communications within a Student Organization at a US University
Today linguistic hybridity is often conceptualized as translanguaging. The present study of translanguaging was a linguistic ethnography, which meant investigating cultural issues as well as linguistic practices. The focus was on bilingual speakers of Vietnamese and English, two "named" languages that differ considerably in morphology, syntax, and orthography. This study, conducted over four and a half months, was situated in the Vietnamese Student Organization of a U.S. university, and it included 37 participants. The research was intended to answer two questions: what forms of translanguaging did these bilinguals use? and what reasons did they provide for instances of translanguaging? In capturing the language use of this community, my role was participant-observer, which entailed observing and audio-recording conversations in three kinds of settings: group meetings, social gatherings, and Facebook communications. Additional insights came from discourse-based interviews, focused on instances of translanguaging by 10 individuals. In the group meetings and Facebook conversations, it was conventional for the major language to be English, whereas in the social gatherings it was Vietnamese. My attention in analyzing these interactions was on patterns of translanguaging that occurred within sentences and those occurring outside sentence boundaries. Overall, most translanguaging occurred intra-sententially, as single words from one language were segmented within a sentence being spoken or written in the other. As to extra-sentential forms, this translanguaging in the group meetings mainly took the form of Vietnamese honorifics, and Facebook conversations included some extra-sentential double postings. Participants provided reasons for translanguaging that included community factors, discourse-related factors, and individual-related factors. This inquiry provides further insights into the multi-competences of bilingual individuals. The Vietnamese-English bilinguals drew flexibly from their linguistic repertoires, merging two languages that are quite different. Use of hybridized language was conventional for them and was central to their practices. This linguistic hybridity was a mutuality—one of the …
"When We Go to Deal with City Hall, We Put on a Shirt and Tie": Gay Rights Movement Done the Dallas Way, 1965-2003
This dissertation examines the gay rights movement occurring in Dallas, Texas, from the mid-twentieth century to present day by focusing on the work of the Dallas Gay and Lesbian Alliance (DGLA), previously known as the Dallas Gay Political Caucus and the Dallas Gay Alliance. Members of that group utilized a methodology they called "the Dallas Way" that minimized mass protests and rallies in favor of using backroom negotiations with the people who could make the changes sought by the movement. The fact that most of the members of the DGLA were white, professional men aided in the success of their methodology. Particularly useful in this type of effort is the use of legal action. The Dallas community supported several lawsuits that attempted to overthrow various versions of sodomy laws in the Texas Penal Code that criminalized an entire population of gay men and lesbians in the state.
