The system of higher education in the United States of America has retained some of its original character yet it has also grown in many ways. Among the contemporary priorities of colleges and universities are undergraduate student learning outcomes and success along with a growing focus on diversity. As a result, there has been a growing focus on ways to achieve compositional diversity and a greater sense of inclusion with meaningful advances through better access and resources for individuals from non-dominant populations. The clearest result of these advances for sexual and gender diversity has been a normalization of lesbian, gay, bisexual, transgender, and queer (LGBTQ) identities through positive visibility and greater acceptance on campus. However, it appears that relatively few institutions have focused on improving academic diversity and students’ cognitive growth around LGBTQ issues. Through historical inquiry and a qualitative approach, this study explored the fundamental aspects of formal LGBTQ studies academic programs at some of the leading American research universities, including Cornell University, the University of Maryland, College Park, and the University of Texas at Austin – a purposeful sample chosen from the Association of American Universities (AAU) member institutions with organized curricula focused on the study of sexual …

POD (Point of Dispensing)-based emergency response plans involving mass prophylaxis may seem feasible when considering the choice of dispensing points within a region, overall population density, and estimated traffic demands. However, the plan may fail to serve particular vulnerable sub-populations, resulting in access disparities during emergency response. Federal authorities emphasize on the need to identify sub-populations that cannot avail regular services during an emergency due to their special needs to ensure effective response. Vulnerable individuals require the targeted allocation of appropriate resources to serve their special needs. Devising schemes to address the needs of vulnerable sub-populations is essential for the effectiveness of response plans. This research focuses on data-driven computational methods to quantify and address vulnerabilities in response plans that require the allocation of targeted resources. Data-driven methods to identify and quantify vulnerabilities in response plans are developed as part of this research. Addressing vulnerabilities requires the targeted allocation of appropriate resources to PODs. The problem of resource allocation to PODs during public health emergencies is introduced and the variants of the resource allocation problem such as the spatial allocation, spatio-temporal allocation and optimal resource subset variants are formulated. Generating optimal resource allocation and scheduling solutions can be computationally hard …

Education remains one of the most gender imbalanced fields, with disproportionately fewer women in higher levels of leadership. Women who reach leadership positions in education experience many triumphs and tribulations during their tenures as principals, assistant superintendents, and superintendents. The experiences of these women in their various administrative levels of leadership can provide important insight into the reasons for their success as women superintendents in Texas. This research has probed the career trajectory of nine women who have successfully attained and retained superintendencies in Texas to determine what career decisions have helped them and the challenges these women have faced in their positions. A qualitative research method, open-ended interviews, yielded several findings of what women considered important in proceeding from teaching through the various levels and ending in becoming superintendents. According to nine successful women superintendents in Texas, there are specific characteristics one can bring to the table that would really make a difference: Communication, collaboration, compassion, preparedness, hard work, and passion. All nine participants overcame challenges when climbing to the higher levels of leadership in education. These women have achieved success in the superintendency, and several factors appear to have played into the success of these women who have …

This research project aims to clarify the factors that impact successful aging in Assisted Living facilities (ALFs) in Denton County, Texas. We hypothesize that social disengagement decreases physical and mental components of quality of life. This exploratory research project employed standardized questionnaires to assess residents in the following domains; HRQOL, social engagement status, level of cognition, depression, and the level of functioning. This study collected data from 75 participants living in five ALFs. The average of Physical Component Scale (PCS) and Mental Component Scale (MCS) was 35.33, and 53.62 respectively. None of the participants had five or more social contacts out of facilities, and two-third of them had two or less social contacts. On average, those participants who were more socially engaged had higher score of MCS compared with disengaged counterparts. The level of physical function significantly affects social engagement, when people with more disabilities are more likely to be socially disengaged. Social engagement and depression significantly impact MCS, when depression is a mediating factor between social engagement and mental component of quality of life. Considering the expansion in aging population in the United States within the next three decades, the demand for high quality long-term care will skyrocket consequently. …

Why do megachurches participate in economic development, and who benefits from their participation? Frumkin's framework for understanding nonprofit and voluntary action and extra-role behavior are theories tested to answer these questions. My research employs a mixed-methods research design conducted in two phases. In phase one, I analyze 42 responses to an online survey to provide data about the prevalence and nature of economic development activities offered by megachurches in the Dallas-Fort Worth and Houston-Sugar Land-Baytown Metropolitan Statistical Areas. Phase two involved 23 semi-structured telephone interviews with megachurch leadership to provide data that explains the rationale for why megachurches offer economic development activities and who benefits. Evidence from this research demonstrates that megachurches are participating in economic development for reasons consistent with both demand-side and supply-side arguments. Findings also show that megachurches take on extra-role behaviors for in response to community expectations and the values of members and staff. Implications for understanding partnership decisions and collaborations between faith-based organizations and local governments are discussed.

The purpose of this paper is to investigate the effect of the "limits of arbitrage" on securities mispricing. Specifically, I investigate the effect of the availability of substitutes and financial constraints on stock mispricing. In addition, this study investigates the difference in the limits of arbitrage, in the sense that it will lead to lower mispricing for these stocks, relative to non-S&P 500 stocks. I also examine if the lower mispricing can be attributed to their lower limits of arbitrage. Modern finance theory and efficient market hypothesis suggest that security prices, at equilibrium, should reflect their fundamental value. If the market price deviates from the intrinsic value, then a risk-free profit opportunity has emerged and arbitrageurs will eliminate mispricing and equilibrium is restored. This arbitrage process is characterized by large number of arbitrageurs which have infinite access to capital. However, a better description of reality is that there are few numbers of arbitrageurs to the extent that they are highly specialized; and they have limited access to capital. Under these condition arbitrage is no more a risk-free activity and can be limited by several factors such as arbitrage risk and transaction costs. Other factors that are discussed in the literature …

Many external parties such as investors, creditors, and regulatory agencies, use a company’s financial statements in their decision-making. In doing so, they rely on audit opinions on whether financial statements are fairly stated. However, evidence suggests that there are factors in the audit environment that influence auditor judgments. For example, nondiagnostic client information dilutes auditor judgments when compared to judgments based on diagnostic information alone, especially for less experienced auditors (Hackenbrack 1992; Hoffman and Patton 1997; Glover 1994; Shelton 1999). High time pressure conditions mitigate this effect by refocusing auditor attention toward relevant client information, therefore reducing the impact of nondiagnostic information (Glover 1994, 1997). This research study examines other common audit environment factors to determine if they too influence audit judgment results. An online questionnaire of 149 auditors, CPAs and other accounting professionals indicate that the inclusion of nondiagnostic client information results in a significant change in auditor judgments. The direction of this change follows a theorized pattern; risk assessments that were initially high are reduced, while those that were initially low are increased. Significance was not consistently found for a workload and PCAOB effect on auditor judgment. However, a comparison of the absolute value of dilution effect means …

The purpose of this study was to investigate the current practices of school and community partnerships in five North Texas elementary schools. In addition, the study focused on the influence community partnerships have on at-risk students based on at-risk indicators data. The literature revealed that when schools, parents, and families work together, students tend to earn higher grades, attend school more regularly, stay in school longer, and enrolled in coursework beyond high school. The target population included approximately 350 administrators, teachers, and paraprofessionals from five North Texas elementary schools. Also included were the respective partners from each of the five elementary schools. This research included online survey instrument and data were gathered and analyzed through a combination of statistical procedures and descriptive and inferential statistics. The results may provide other schools with a profile of school and community partnerships that can be implemented as a method to help their at-risk student populations. Findings included a descriptive analysis of factors that contributed to the success of community engagement efforts as well as those factors that limited those efforts. A secondary purpose of this study was of continuous improvement in developing these approaches through a goal-setting approach. Schools included in the study …

It has become something of a cliché for contemporary scholars to assert that Madison turned Montesquieu on his head and thereafter give little thought to the Frenchman’s theory that republics must remain limited in territorial size. Madison did indeed present a formidable challenge to Montesquieu’s theory, but I will demonstrate in this dissertation that the authors of the Federalist Papers arrived at the extended sphere by following a theoretical pathway already cemented by the French philosopher. I will also show that Madison’s “practical sphere” ultimately concedes to Montesquieu that excessive territorial size and high levels of heterogeneity will overwhelm the citizens of a republic and enable the few to oppress the many. The importance of this dissertation is its finding that the principal mechanism devised by the Federalists for dealing with factions—the enlargement of the sphere—was crafted specifically for the purpose of moderating interests, classes, and sects within an otherwise relatively homogeneous nation. Consequently, the diverse republic that is America today may be exposed to the existential threat anticipated by Montesquieu’s theory of size—the plutocratic oppression of society by an elite class that employs the strategy of divide et impera.

The 2010 Deepwater Horizon oil spill resulted in the accidental release of millions of barrels of crude oil into the Gulf of Mexico (GoM). Photo-induced toxicity following co-exposure to ultraviolet (UV) radiation is one mechanism by which polycyclic aromatic hydrocarbons (PAHs) from oil spills may exert toxicity. Blue crab (Callinectes sapidus) are an important commercial and ecological resource in the Gulf of Mexico and their largely transparent larvae may make them sensitive to PAH photo-induced toxicity. Mahi-mahi (Coryphaena hippurus), an important fishery resource, have positively buoyant, transparent eggs. These characteristics may result in mahi-mahi embryos being at particular risk from photo-induced toxicity. Red drum (Sciaenops ocellatus) and speckled seatrout (Cynoscion nebulosus) are both important fishery resources in the GoM. They spawn near-shore and produce positively buoyant embryos that hatch into larvae in about 24 h. The goal of this body of work was to determine whether exposure to UV as natural sunlight enhances the toxicity of crude oil to early lifestage GoM species. Larval and embryonic organisms were exposed to several dilutions of water accommodated fractions (WAF) from several different oils collected in the field under chain of custody during the 2010 spill and two to three gradations of natural …

The past decade has become rife with an eagerness to integrate new digital technology into teaching. While there have been decades of research done on the importance of curriculum and pedagogy on student engagement, findings of actual technology integration are scarce. Moreover, what does it take to engage students in classroom activities and lessons when technology is introduced? The purpose of this study was to explore how digital technology, when integrated into classroom teaching and activities, impacted the students-classroom engagement based on the interim-cognitive, meta-cognitive, motivational, and behavioral markers. This was explored in a Texas public high school across the four core classes (English, Math, Science, and Social Studies. Data was collected in the form of observational field notes, transcripts of recorded lessons, and Likert-scaled surveys. Thematic analysis was used in analyzing qualitative data, Pearson’s correlation of those components found by factor analysis verified three of the five themes identified from the thematic analysis with statistical significance. The findings suggest that mere use of technology does not have a profound impact on student engagement. Instead, technology tends to amplify the existing classroom culture and social norms agreed upon between the teacher and their students. Texas teachers and students are also …

To date, traditional behavioral interventions have done little to reduce the prevalence and transmission of HIV among African American men who have sex with men (AAMSM), a highly at risk group. Some researchers theorize that the lack of success may be because these interventions do not address contextual factors among AAMSM. Community-based participatory research (CBPR) is one approach to research with the potential to lead to effective interventions in the future. CBPR is a collaborative, mixed-methods and multidisciplinary, approach to scientific inquiry, which is conducted with, and within, the community. The current study follows the CBPR approach to engage and develop a relationship with the African American communities in the Dallas/Fort Worth Metroplex. Contextual issues were discussed in order to identify emerging themes regarding HIV health related issues among AAMSM to provide the groundwork for continued CBPR research and future interventions with AAMSM in the Dallas/Fort Worth Metroplex. To accomplish this goal, researchers began the CBPR process by conducting interviews and focus groups with a sample of approximately 62 (34 from key informant interviews, 28 from focus groups [gender balanced]) AIDS service organization leaders and workers, advocates, medical doctors and community members with first-hand knowledge of HIV health issues in …

Given issues in education concerning teacher shortages, the omnipresence of alternative certification programs and the growth of online programs in higher education, this study investigated teacher retention for 77 secondary education teachers who completed an online teacher preparation program in Texas. Teacher retention was examined from 2003-2013 and investigated the influence of factors such personal characteristics, working conditions and school setting characteristics on teacher retention. Data was collected electronically utilizing a survey instrument designed by two teacher education experts and I. A total of 21 variables and two open-ended questions were investigated using the survey instrument. Exploratory factor and hierarchical multiple regression analyses were conducted to identify a multi-factor model for teacher retention utilizing the participants' survey responses. These analyses yielded evidence of the program's effectiveness in preparing teachers for long careers. Specifically, the areas of program support, field experience, and classroom management were statistically significant factors that contributed positively to teacher retention. Additionally, variables outside the program, were examined. These factors included personal characteristics, working conditions, and school setting factors. The predictor model accounted for 56% of the variance; F (17, 54) = 3.015; p = < 0.001. In particular, working conditions contributed to 41% of the variance associated …

In order to better understand variations of health behaviors between US-born and foreign-born elderly Asian Americans (65+) in the United States, the research aims to explore relationships among health outcomes, healthcare utilization, and sociodemographic characteristics. Data from the National Health Interview Survey 1998-2012 is used to construct structural equation models for the US born group and for the foreign born group. The results found that there is a reciprocal relationship between health outcomes and healthcare utilization in both groups. Use of healthcare services can positively affect health outcomes, while better health outcomes reduce the need for healthcare utilization. In addition, some sociodemographic characteristics, such as age, sex, and marital status have a direct effect on health outcomes, but some others, such as education, family size and combined family income, have an indirect effect on health outcomes via healthcare utilization. The region of residency has both direct and indirect effects on health outcomes. Regarding the effects of predictors on health outcomes, US-born elderly Asians usually receive more health advantages from using institutional health services than foreign-born elderly Asians. Practitioners, social gerontologists, and policy makers should be cautious about assuming that there is a positive impact of increased healthcare utilization on health …

The need to spur innovation and improve student performance initiated the formation of, under different legislative acts, charter schools that include variations of traditional public schools. With the enthusiasm and level of investment going into the formation of charter schools, it is necessary to explore whether these schools have achieved their objectives. This study explored whether Texas open enrollment charter schools perform bettered compared to Texas public schools. The study applied a causal comparative quantitative research design. School data on graduation and dropout rates, college preparation, attendance rates, and overall performance were analyzed quantitatively. Student achievement data available for statistical analysis includes student performance on the Texas Assessment of Knowledge and Skills (TAKS) state assessment from 2007 to 2011. Data analysis for race, special programs, at risk, economically disadvantaged, and limited English proficiency was incorporated. Descriptive statistics and analysis of variance techniques were included in the data analysis. The analysis extended to post hoc tests to determine variables that caused variation. The study found Texas open-enrollment charter schools had more African American students but fewer Whites compared to public schools. Students in public schools performed better than those in charter schools, and Whites yielded the best performance. Charter schools had …

Today’s military encompasses a wide variety of families who are affected by deployments in multiple and complex ways. Following deployments, families must reconnect in their relationships and reestablish their way of life. Appropriate and effective communication during this time is critical, yet many military couples struggle with this process. Moreover, student service members/veterans and their families are in a unique position. In addition to coping with changes in their marital relationship, student veterans may feel isolated or unsupported on college campuses, often experiencing anxiety, depression, posttraumatic stress, or suicidality. The current study seeks to bridge the gap between the military family literature and the student service member/veteran literature by examining how deployment experiences, mental health issues, and communication patterns influence post-deployment relationship adjustment among student veterans. Analyses tested whether communication style and/or current mental health concerns mediate associations between combat experiences and couples’ relationship adjustment, as well as between experiences in the aftermath of battle and relationship adjustment. Results suggest that although posttraumatic stress is significantly related to deployment experiences among student veterans, participants report no significant negative effects of deployment on relationship adjustment. Communication style, however, was significantly associated with relationship adjustment, and a lack of positive communication was …

With the increase in emergent bilinguals and higher standards for all, the challenge for educational stakeholders is to fully utilize dual language programs as a prominent means toward meeting and surpassing rigorous state and national standards. Part of maximizing dual language programs’ impact, and the purpose of this study, was to provide detailed analyses of program models and student biliteracy development. Thus, the research questions sought to explore the level of understanding and implementation of dual language programs in general and the biliteracy component in particular at each campus, before documenting the second through fifth grade English and Spanish reading biliteracy trajectories of students at each school. Both campuses experienced more challenges in the implementation of the program structure, staff quality, and professional development rather than in curriculum and instruction. Furthermore, although both campuses’ students experienced positive trajectories towards biliteracy by the end of fifth grade, each campus was characterized by different rates and correlation between English and Spanish reading growth in each grade. Finally, the researcher conducted a split plot MANOVA to examine how much variance in the biliteracy trajectories was explained by school attendance, gender, initial English oral language and initial Spanish oral language; only school of attendance …

Banda is a rural Mexican brass band genre from the state of Sinaloa that became popular among immigrant populations of Los Angeles in the 1990s. In contemporary banda, the tuba has acquired a more prominent role than it held in traditional banda. The tuba has shifted from the traditional background harmonic and rhythmic function to a significant and new placement with the front line melodic instruments. The focus on tubas in modern incarnations of banda has helped it become a staple in acoustic and accordion genres such as sierreña and norteña. In many Mexican-American regional ensembles, the prominence of the tuba and its placement within the group represents a shift in its cultural significance, a stronger connection to the Mexican history and cultural roots, in the Mexican-American music community of southern California. This paper uncovers some of the motives and significance behind these recent changes in the role of the tuba in Mexican-American regional genres as well as the cultural connection that the tuba provides for Mexican-Americans in southern California to traditional Mexican music culture.

Religion/spirituality is a salient facet of identity for many college students, yet addressing issues related to spirituality/religion is contentious in many higher education institutions. Prior research has shown that various other facets of identity, including race/ethnicity, gender, and sexual orientation, affect a student’s perception of campus climate, but religious/spiritual identity has not been examined in the same manner. Using confirmatory factor analysis and structural equation modeling, this study empirically tests the addition of religion/spirituality to the campus climate theory developed by Hurtado et al. (1999). Data came from the 2010 College Senior Survey administered by the Higher Education Research Institute at the University of California, Los Angeles. Results indicate that religious and spiritual identity have significant direct effects on the perception and other aspects of campus climate. Future research is needed to extend the understanding between religious and spiritual identity and the perception of campus climate.

The Online Student Connectedness Survey (OSCS) was introduced to the academic community in 2012 as an instrument designed to measure feelings of connectedness between students participating in online degree and certification programs. The purpose of this study was to examine data from the instrument for initial evidence of validity and reliability and to establish a nomological network between the OSCS and similar instruments utilized in the field. The study utilized sequential exploratory factor analysis- confirmatory factor analysis (EFA-CFA) and correlational analysis to assess results of the data. Students enrolled in online courses at higher education institutions located in the United States served as the sample for this study. Three instruments were used during the study. The OSCS was administered first so that the factor structure could be examined for factor validity. Once confirmed, the Classroom Community Scale (CCS) and the Community of Inquiry Scale (COI) served as the instruments to examine nomological validity through correlational analysis of data.This study provided evidence of factor validity and reliability for data from the OSCS. After the initial EFA-CFA, the four-factor structure held, and 16 of the 25 original items remained for nomological testing. Statistically significant correlations were demonstrated between factors contained in the …

Currently, neuropsychologists rely on assessment instruments rooted in century old theory and technology to make evaluations of military personnel’s readiness to return-to-duty or return to their community. The present study sought to explore an alternative by evaluating the validity of a neuropsychological assessment presented within a virtual reality platform. The integration of a neuropsychological assessment into a cognitively and emotionally demanding virtual environment – reminiscent of a combat experience in Iraq – offers a more ecologically valid manner in which to evaluate the cognitive skills required in theater. U.S. military veterans’ (N = 50) performance on the Virtual Reality Stroop Task (VRST) was compared with performance on a paper-and-pencil, a computer adapted version of the Stroop task, and the subtests included in the Automated Neuropsychological Assessment Metrics-4 (ANAM4) TBI-MIL test battery. Results supported the validity of the VRST, indicating it demonstrates the typical Stroop effect pattern. The emotional salience of the VRST resulted in slowed reaction time compared to the ANAM Stroop. Further, the complex interference condition of the VRST offers opportunities for evaluation of exogenous and endogenous attentional processing. In the evaluation of threat, participants were noted to perform more accurately and more quickly in low threat versus high …

This literary/historical novel details the life of African-American Deputy US Marshal Bass Reeves between the years 1838-1862 and 1883-1884. One plotline depicts Reeves’s youth as a slave, including his service as a body servant to a Confederate cavalry officer during the Civil War. Another plotline depicts him years later, after Emancipation, at the height of his deputy career, when he has become the most feared, most successful lawman in Indian Territory, the largest federal jurisdiction in American history and the most dangerous part of the Old West. A preface explores the uniqueness of this project’s historical relevance and literary positioning as a neo-slave narrative, and addresses a few liberties that I take with the historical record.

In conjunction with the Texas Technology Immersion Pilot program (TIP), the State of Texas implemented a four-year annual evaluation called the Evaluation of the Texas Technology Immersion Pilot (eTxTiP). It focused on the technology immersion experience through one-to-one mobile technology of sixth grade students in 22 selected middle schools. Initial findings suggested academic growth, especially in math, increased rigor of student work, greater teacher collaboration, a more positive school environment, and transformation of instructional practices. This study focused on one of the original schools selected to participate in the TIP program, exploring the impact over time of one-to-one mobile technology on one group of students over an 8-year period beginning with their third grade year. The selected school’s demographic makeup reflected a large number of schools within the state, including its size, rural location and economically disadvantaged student population. Based on an interrupted time series design, state assessment data was analyzed using a piecewise growth model. The study revealed no statistically significant academic growth in reading and math performance among the participants.

Many students and their families do not understand the impact of students’ involvement in gifted or advanced academics educational programs and their potentially positive effects and challenges. Nationally African American students are underrepresented in gifted and advanced academics courses in high schools; however, African American students and families often do not advocate for their inclusion in these educational pathways. A survey of literature supporting this study of voices of African American families concerning gifted and advanced academics participation focused on (1) the historical underpinnings for equity and excellence for African American and for gifted and advanced academics learners, (2) how the lack of an agreed upon definition of gifted and advanced academics by the professional field might contribute to the problem, and (3) how African American parents made educational decisions for and with their children, especially concerning college. Employing semi-structured interviews and a focus group, this qualitative case study examined how four students from each of three groups, gifted and talented, advanced academics, and neither, and a representative group of their parents perceived these programs and their children’s involvement in them within the framework provided by a single school district. African American families in this study asked for a partnership …
