Estimation Methods For Bayesian Exponential Random Graph Models Under The Horseshoe Prior., Pamela Linares

Electronic Theses and Dissertations

Networks are powerful tools for modeling the complexity of social interactions, biological systems, and information spread. A leading statistical frameworks for analyzing network data are Exponential Random Graph Models (ERGMs), which provide a principled approach to capturing structural dependencies. However, ERGMs remain challenging to estimate, especially in sparse or high-dimensional settings where models suffer from degeneracy and unstable parameter inference. This paper proposes a penalized Bayesian approach to ERGMs that utilizes the horseshoe prior, a sparsity-inducing global-local shrinkage prior. This prior offers robust regularization while preserving important signals, improving estimation by shrinking irrelevant parameters and reducing the impact of extreme …

A Pandemic’S Potential To Haunt: A Longitudinal Look At The Professional Wellbeing Of Tn’S Infant And Early Childhood Mental Health (Iecmh) Workforce, Robyn A. Dolson

Electronic Theses and Dissertations

Infant and Early Childhood Mental Health (IECMH) providers engage in uniquely relational work with high-risk families that expose them to the full advantages (i.e., compassion satisfaction [CS]) and disadvantages (e.g., burn-out [BO]) of a helper role. Though the pandemic seemed poised to escalate disadvantage, most early pandemic studies found high CS alongside elevated BO. Unfortunately, as COVID-19 has continued, CS has declined while BO has increased. Given the delayed COVID-19 impact on children, these changes may be particularly acute for IECMH providers. Using a longitudinal cohort of 27 IECMH providers, this study aimed to describe and quantify changes in professional …

Impact Of Community-Based Care Model On Child Welfare Professionals: A Study Of Workload, Job Satisfaction, And Turnover Intent, Kerri Taylor

Electronic Theses and Dissertations

Much of the research on child welfare workers is in a traditional service model. However, there is a lack of empirical studies regarding childcare workers in a community-based care model. This study examines whether transitioning to the community-based model has positively impacted workers’ perspectives regarding turnover intention, job satisfaction, and workload manageability. A cross-sectional survey design was used with convenient sampling from a Texas Department of Family Protective Service Region that transitioned to the CBC model. The single source continuum contractor employed a sample of 125 potential respondents in the selected region. A total of 43 permanency workers responded to …

An Examination Of Racial And Ethnic Differences In Internalized Mental Health Stigma And Perceived Mental Health Barriers Due To Stigma Among Women Veterans, Christe’An D. Iglesias

Electronic Theses and Dissertations

The stigma associated with mental illness can serve as a barrier for receiving treatment. Veterans may avoid seeking care due to stigma-related negative beliefs about one’s self or others. Research suggests that the stigma of mental illness can adversely impact service utilization. Although studies have shown that racial and ethnic minoritized individuals are more likely to experience poor mental health outcomes, no studies have examined how mental illness stigma differs across racial groups among women veterans. The objective of this secondary analysis is to examine how internalized mental health stigma and perceived barriers to access to care related to mental …

A Grounded Theory Inquiry Into The Pedagogical Socialization Of Graduate Students Within Graduate Quantitative Methods Courses, Amanda Kay Thomas

Electronic Theses and Dissertations

Quantitative methods are one of the most highly technical fields of study within social sciences graduate programs. Although classroom pedagogy is an important factor connected to student success within graduate quantitative methods courses little is known on the pedagogical socialization experiences of masters and doctoral students. The purpose of this grounded theory inquiry was to discover graduate students perspectives on their pedagogical socialization experiences and the norms, values and role expectations transmitted during the teaching and learning of quantitative methods. Narrative data was collected from in-depth interviews among a theoretical sample of 31 masters and doctoral students enrolled in introductory, …

Measuring The Connective Action Of Black Lives Matter Activists: A Psychometric Investigation Into Twitter Data, Paige Alfonzo

Electronic Theses and Dissertations

Many protest movements from the last twenty-first century have become increasingly networked and personalized. Several scholars have tapped into this change coining terms such as participatory action, digitally mediated action, computer-mediated communication, issue-based organization, and what I focus on in this project, connective action. Building on the ideas percolating across the literary landscape at the time, Bennett and Segerberg (2012) introduced the logic of connective action based on emergent characteristics they observed in post-2010 large-scale social movements. Both the logic of connective action and related work have become deeply ingrained in today's social movement scholarship. As such, I felt it …

Childhood Abuse, Religiosity, And Opioid Use: Findings From The National Epidemiologic Survey On Alcohol And Related Conditions Data, James E. Lewis

Electronic Theses and Dissertations

Religiosity is adopting a belief system surrounding concepts of purpose, meaning, and value through an institution that has already defined these concepts prior to the individual member attending and that member’s degree of participation. Religiosity does have protective factors against negative health outcomes. This protective influence was evaluated in this study. Data from Wave 2 of the National Epidemiologic Survey on Alcohol and Related Conditions were examined to learn about the relationship between protective effects of religious participation on substance abuse, and whether this association weakened for individuals who have experienced higher levels of childhood abuse. A binary logistic regression …

Visitor Characteristics, Attitudes, And Management Preferences Of The Bob Marshall Wilderness Complex, Samuel J. Rhodes

Electronic Theses and Dissertations

The Bob Marshall Wilderness Complex (BMWC) encompasses 3 federal wilderness areas and spans over 1.5 million acres of iconic mountains and valleys in northwestern Montana. Here visitors can find a plethora of recreation opportunity that give access to some of the most rugged country that can be found in the lower 48 states. However, managing wilderness areas comes with the challenge of both preserving the natural resources found within their borders and enabling opportunities for recreational experiences. Wilderness social scientists always have striven to determine the type of visitors coming to wilderness, and see what sorts of experiences they pursue. …

Comparative Spending Of Medicaid Dollars On Child Participants Of Kentucky’S Sobriety Treatment And Recovery Teams Program Versus A Matched Comparison Group., Matthew Thomas Walton

Electronic Theses and Dissertations

Child protective services agencies have long observed the complicating role that parental substance use and addiction plays in cases of child maltreatment. Families who struggle with these problems present unique challenges for child welfare professionals. These families are typically more difficult to engage, more likely to have children removed from the home, and have poorer outcomes when compared to other families. These poorer outcomes often include health problems. Addiction has well-known effects on health, and the specific manifestations of these problems for parents have been documented for years in child protection casework. However, what has been less investigated are the …

Outcomes Of Mental Health Crises When Mental Health Professionals Partner With Mental Health Deputies, Melissa Kay Murray

Electronic Theses and Dissertations

Law enforcement has historically been on the frontlines of the mental health crisis. This expected role is difficult as police officers are not trained as mental health professionals. Collaboration between police officers, mental health professionals, and mental health authorities have produced integral models to assist with the mental health crisis. Crisis intervention teams (CIT), mobile crisis units, and street triage models are highlighted to gain understanding of the components of these models. This study desires to examine a collaborative, recently implemented mental health deputy grant program aimed at diverting mentally ill individuals in crisis from contact with the criminal justice …

Handgun Carrying Patterns And Suicide Risk Among Youth., Teresa Jane Mcgeeney

Electronic Theses and Dissertations

Recent data have shown marked increases in carrying of handguns among youth. Though firearms are often discussed using a lens of prevention of violence towards others, the majority of firearm deaths are suicides. Youth suicide has also seen steady increases across the United States in the past decade, demanding urgent solutions to curb this concerning trend. Klonsky and May’s Three Step Theory (3ST) outlines three primary steps that lead to death by suicide and proposes that access to and familiarity with lethal means, such as firearms, make up a critical component of the etiology of suicide. With youth suicide and …

A Systematic Assessment Of Socio-Economic Impacts Of Prolonged Episodic Volcano Crises, Justin Peers

Electronic Theses and Dissertations

Uncertainty surrounding volcanic activity can lead to socio-economic crises with or without an eruption as demonstrated by the post-1978 response to unrest of Long Valley Caldera (LVC), CA. Extensive research in physical sciences provides a foundation on which to assess direct impacts of hazards, but fewer resources have been dedicated towards understanding human responses to volcanic risk. To evaluate natural hazard risk issues at LVC, a multi-hazard, mail-based, household survey was conducted to compare perceptions of volcanic, seismic, and wildfire hazards. Impacts of volcanic activity on housing prices and businesses were examined at the county-level for three volcanoes with a …

An Evaluation Of Geotagged Twitter Data During Hurricane Irma Using Sentiment Analysis And Topic Modeling For Disaster Resilience, Ike Robert Vayansky

Electronic Theses and Dissertations

Disasters require quick response times, thought-out preparations, overall community, and government support. These efforts will ensure prevention of loss of life and reduce possible damages. The United States has been battered by multiple major hurricanes in the recent years and multiple avenues of disaster response efforts were being tested. Hurricane Irma can be recognized as the most popular hurricane in terms of social media attention. Irma made landfall in Florida as a Category 4 storm and preparation measures taken were intensive thus providing a good measure to evaluate in terms of efficacy. The effectiveness of the response methods utilized are …

Performance Evaluation Of Logistic Regression, Linear Discriminant Analysis, And Classification And Regression Trees Under Controlled Conditions, Cahit Polat

Electronic Theses and Dissertations

Logistic Regression (LR), Linear Discriminant Analysis (LDA), and Classification and Regression Trees (CART) are common classification techniques for prediction of group membership. Since these methods are applied for similar purposes with different procedures, it is important to evaluate the performance of these methods under different controlled conditions. With this information in hand, researchers can apply the optimal method for certain conditions. Following previous research which reported the effects of conditions such as sample size, homogeneity of variancecovariance matrices, effect size, and predictor distributions, this research focused on effects of correlation between predictor variables, number of the predictor variables, number of …

A Cross-Sectional Exploration Of Household Financial Reactions And Homebuyer Awareness Of Registered Sex Offenders In A Rural, Suburban, And Urban County., John Charles Navarro

Electronic Theses and Dissertations

As stigmatized persons, registered sex offenders betoken instability in communities. Depressed home sale values are associated with the presence of registered sex offenders even though the public is largely unaware of the presence of registered sex offenders. Using a spatial multilevel approach, the current study examines the role registered sex offenders influence sale values of homes sold in 2015 for three U.S. counties (rural, suburban, and urban) located in Illinois and Kentucky within the social disorganization framework. Homebuyers were surveyed to examine whether awareness of local registered sex offenders and the homebuyer’s community type operate as moderators between home selling …

Consumers' Perceptions Of Voluntary And Involuntary Deconsumption: An Exploratory Sequential Scale Development Study, Kranti K. Dugar

Electronic Theses and Dissertations

This exploratory sequential mixed methods study of scale development was conducted among baby boomers in the United States to render conceptual clarity to the concepts of voluntary and involuntary deconsumption, to explore deconsumption behavior under the tenets of the attribution theory of motivation, and to examine the components, structures, uses, and measurement properties of scales of voluntary and involuntary deconsumption. It was also an attempt to reiterate the importance of the baby boomer segment(s) for marketing practitioners based on growth, economic viability, and the power of influence, and to establish a deep understanding of the deconsumption processes, which could enable …

Determining Public Perceptions Toward Wildland Fire In The Veluwe Region Of The Netherlands, Amy Brennan

Electronic Theses and Dissertations

The Netherlands has been facing a growing threat of wildfires due to warmer

and drier weather patterns. The purpose of this study was to identify public

perceptions toward wildland fire in the forested Veluwe region of the country. The

Dutch have little experience with wildland fires or fire as a management tool. In a

collaborative effort between Stephen F. Austin State University and the Instituut

Fysieke Veiligheid, the Dutch public safety agency, a survey was distributed to

residents and visitors to the Veluwe to reveal and quantify public opinions and

perceptions regarding wildland fire and public expectations of government
