Chronic Homelessness and the Aging Population: Findings in a Homeless Sample from Arkansas (open access)

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 …

Demand and Supply Explanation: Nonprofit Size in Homeless Service Area (open access)

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 …

Disaster Preparedness in Escambia County Florida: The Influence of Oral Narratives (open access)

Disaster Preparedness in Escambia County Florida: The Influence of Oral Narratives

This work addresses hurricane preparedness in Escambia County, Florida. It explores preparing for hurricanes as an informal learning process occurring within personal networks and embedded in beliefs, values, and attitudes. Findings reveal that participants learned to prepare from their parents in childhood and improved upon that knowledge through direct experience in adulthood. Later, they passed this knowledge on to their children as well as co-workers. These preparations are embedded in beliefs of self-determination and attitudes of endurance. However, this body of knowledge and their respective practices are not equally accessible to all. Recommendations are provided so local organizations can incorporate local knowledge and practices with preparedness improvement efforts and foster social cohesion as well.

Educator Perceptions of Forces Influencing Implementation of a Statewide Writing Portfolio Assessment (open access)

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 …

Effects of Cultural Intelligence and Social Support on Adjustment of International Students (open access)

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.

Forging Their Legacy: Cooperation and Accommodation in the Lower Rio Grande Valley, 1848-1870 (open access)

Forging Their Legacy: Cooperation and Accommodation in the Lower Rio Grande Valley, 1848-1870

Forging Their Legacy: Cooperation and Accommodation in the Lower Rio Grande Valley is an examination of the relationships created during the mid-nineteenth century between Anglo and Tejano elites in the five counties that make up the Lower Rio Grande Valley. Conducted through a quantitative lens, the five-chapter study seeks to demonstrate that, although the period between 1848 and 1870 was fraught with conflict and violence, the Anglo and Tejano elite of the Lower Rio Grande Valley came together in cooperation in order not only to survive these troubling times but to prosper. The thesis begins by identifying and analyzing the economic and political elite in the Lower Rio Grande Valley during the 1850s. A new crop of Anglo immigrants arrived with the Mexican-American War, but only a small number willing to assimilate to local Tejano culture were able to leave their mark on the Lower Valley. Chapter 4 relates the effect of the Civil War on the elite of the Lower Valley. It explores the profitable cotton trade during the war and the struggle that both Anglo and Tejano elites faced during Reconstruction. The thesis concludes with a macro-analysis of the twenty-two-year period from 1848-1870. It summarizes overall trends found …

Long-Term Citizen Science Water Monitoring Data: An Exploration of Accuracy over Space and Time (open access)

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 …

Reclaiming Female Virtue: Social Hygiene, Venereal Disease and Texas Reclamation Centers during World War I (open access)

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 …

Relationships between Job Satisfaction, Work Engagement, and Turnover Intention of Health Science Teachers (open access)

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.

Survey of Texas Secondary Transition and Employment Designees' Use of Evidence-Based Practices (open access)

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.

Untrammeled by Man? An Ethnographic Approach of Outdoor Recreation Management in Charon's Garden Wilderness (open access)

Untrammeled by Man? An Ethnographic Approach of Outdoor Recreation Management in Charon's Garden Wilderness

Charon's Garden Wilderness Area within the Wichita Mountains National Wildlife Refuge in Oklahoma is a landscape that is granted federal protection through the Wilderness Act of 1964. The discourse of wilderness management is influenced by governmental policies and practice which organize knowledge surrounding the natural landscape, like with the formation and semantics of the Wilderness Act. The Wilderness Act establishes characteristics that are designed to monitor and control the landscape and serve as a baseline and criterion for further wilderness preservation. These characteristics render the wilderness space as governable. Conservation management alternatives are identified which bypass the duality of nature from western society suggested by the discourse of environmental policy. These alternatives are understood under two notions of behaviors and perceptions. The project's goal is to uncover wilderness users' recreation behaviors and perceptions of wilderness as a designated space. Through understanding and assessing user's behaviors and perception of wilderness, alternative policies and practices that offer sustainable management practices and recreation opportunities can be developed.

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.

"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.

William's America: Royal Perspective and Centralization of the English Atlantic (open access)

William's America: Royal Perspective and Centralization of the English Atlantic

William III, Prince of Orange, ascended the throne of England after the English Glorious Revolution of 1688. The next year, the American colonists rebelled against colonial administrations in the name of their new king. This thesis examines William's perception of these rebellions and the impact his perception had on colonial structures following the Glorious Revolution. Identifying William's modus operandi—his habit of acceding to other's political choices for expediency until decisive action could be taken to assert his true agenda—elucidates his imperial ambitions through the context of his actions. William, an enigmatic and taciturn figure, rarely spoke his mind and therefore his actions must speak for him. By first establishing his pattern of behavior during his early career in the Netherlands and England, this project analyzes William's long-term ambitions to bring the Americas under his direct control following the 1689 rebellions and establish colonial administrations more in line with his vision of a centralized English empire.

Wrestling with the Past: How National Wrestling Lost Its Regional Heritage (open access)

Wrestling with the Past: How National Wrestling Lost Its Regional Heritage

Through a combination of stringent and deceptive corporate control of sources, as well as an academic blind spot on certain low-brow subcultures, there has been a lack of serious study of the various regional professional wrestling traditions that crossed the United States until the end of the 1980s. An in-depth examination of a wide range of books, newsletters, and interviews shows a rich history with a deep economic, social, and creative diversity that has been largely ignored as the industry has moved towards monopolization under Vincent Kennedy McMahon. The various regions are divided into three groups: those that closed on their own, those that fell in competition with McMahon, and those that survived into the era of national corporate pro wrestling. This organization challenges the narrative that regional pro wrestling came to an end solely due to the business power of McMahon. The first group looks at Northern California, Southern California, Georgia, and North Texas. The second group examines the independent wrestling companies Mid-South Wrestling and the American Wrestling Association, and their attempts to compete with McMahon on a national level. The group also explores how the intense local fan bases in Portland and Memphis buoyed the local pro wrestling …

Advancing a Community's Conversations About and Engagement with Climate Change

The goal of this project completed for the Greater Northfield Sustainability Collaborative (GNSC) was to understand how Northfield, Minnesota citizens are experiencing climate change. Thirty individuals were interviewed to find out what they know about climate change, what actions they are taking, what they think the solutions are to the problems, and what barriers they have to more fully engaging with climate change issues. The interview results are intended to promote and advance the community's discussion on climate change via social learning and community engagement activities such as town hall forums and community surveys. These activities encourage citizens in the community to have direct input into the development of the community's climate action plan (CAP). Analysis of the interviews showed that the interviewees are witnessing climate change, that most are taking at least some action such as recycling or lowering thermostats, that they can name barriers to their own inaction, that they say communication about climate change remains confusing and is not widespread in Northfield, and that they are able to provide numerous suggestions for what the local and broader leadership should be doing. The analysis also showed wide individual variation within the group. Interviewees who were less knowledgeable about …

Bread, Bullets, and Brotherhood: Masculine Ideologies in the Mid-Century Black Freedom Struggle, 1950-1975 (open access)

Bread, Bullets, and Brotherhood: Masculine Ideologies in the Mid-Century Black Freedom Struggle, 1950-1975

This thesis examines the ways that African Americans in the mid-twentieth century thought about and practiced masculinity. Important contemporary events such as the struggle for civil rights and the Vietnam War influenced the ways that black Americans sought not only to construct masculine identities, but to use these identities to achieve a higher social purpose. The thesis argues that while mainstream American society had specific prescriptions for how men should behave, black Americans were able to select which of these prescriptions they valued and wanted to pursue while simultaneously rejecting those that they found untenable. Masculinity in the mid-century was not based on one thing, but rather was an amalgamation of different ideals that black men (and women) sought to utilize to achieve communal goals of equality, opportunity, and family.

A Cross-Cultural Study of Adult Attachment, Social Self-Efficacy, Familismo, and Psychological Wellbeing (open access)

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 …

Effects of Deepwater Horizon Crude Oil on Visual Function in Teleost Fishes (open access)

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 …
