Crash Injury Severity Prediction With Artificial Neural Networks, Rima Abisaad

Dissertations

Motor vehicle crashes are one of our nation's most serious social, economic and health issues. They are the leading cause of death among children and young adults, killing approximately 1.35 million people each year. Providing a safe and efficient transportation system is the primary goal of transportation engineering and planning. To help reduce traffic fatalities and injuries on roadways, crash prediction models are used to forecast the injury severity of potential crashes and apply precautionary countermeasures accordingly. Most of these models are reactive as they use historical crash data to categorize crash-related factors. Recently, advancements have been made in developing …

Employees' Expectations Of Leadership Development Programs And Their Effects On Anticipated Voluntary Employee Turnover And Organizational Commitment, Candace Johnson

Dissertations

Employee retention and commitment have gained attention over the past years (Mutsuddi, 2016). Commitment is the link that connects an individual to their organization, thereby decreases the probability of turnover (Allen & Meyer, 1990; Hague et al., 2019). According to Mutsuddi (2016), decreasing employee turnover remains a critical element for sustainment in any organization. However, most organizations invest in policies and practices to increase employee commitment; those same practices can lead to employee turnover (Mutsuddi, 2016). This study explores the effects of leadership development programs and their impact on organizational commitment and anticipated voluntary employee turnover. A qualitative research design …

The Understanding Of Digital And Multimedia Evidence (Dme) By Attorneys And Digital Forensic Examiners (Dfe) Within The United States Criminal Justice System, Joseph Levi White

Dissertations

One goal of this research was to determine potential themes that may influence the understanding of Digital and Multimedia Evidence (DME) by attorneys and Digital Forensic Examiners (DFE) within the United States Criminal Justice System. Qualitative semi-structured interviews were conducted to gather information from experienced criminal attorneys and DFEs regarding potential influences on their understanding of DME. The results of these interviews were transcribed, and the data coded to allow for qualitative analysis. Five themes were developed from this data and are thought to play a role in understanding of DME by attorneys and DFEs: motivation for involvement in the …

The Formation Of Proxy Force And External State Relationships: Prospect Theory And Proxy Force Decision Making, Brandon Temple

Dissertations

Proxy war is a common tactic employed by great powers as a safer alternative to direct conflict, especially in the era of nuclear weapons. While proxy war is common, there is a lack of research on the formation of proxy-external state relationships. Previous research has typically examined the phenomena of proxy war through the perspective of the external state power, leaving a gap in the literature. This dissertation fills that gap by assessing the conditions under which armed groups enter into proxy relationships with external states. Using prospect theory as a framework for understanding more clearly armed group decision making …

Should We Wear A Mask? Household Assessment Of Mask Wearing For Covid-19 In Ya’An, China, Leonard Peterson

Dissertations

In late 2019 and 2020, the novel SARS-CoV-2 virus spread worldwide and resulted in the COVID-19 pandemic, the second deadliest pandemic in modern history since the 1918 influenza pandemic. Since the virus was novel, no therapeutics and vaccines existed. Effective implementation of non-pharmaceutical interventions was essential to reducing the transmission of the disease until the discovery of effective therapeutics and vaccines. This study explores the influence of the facilitating protective action attribute on adopting mask-wearing as a protective action in Ya’an, Sichuan Province, China. The study found that perceptions of mask effectiveness to reduce the probability of contracting and spreading …

Examining Media Dependency And Parasocial Relationship On Protective Action Behaviors During Covid-19, Amy Hyman

Dissertations

The COVID-19 pandemic illuminated the significant role that mass media plays in disseminating messages to the public during disasters and public health crises. Information disseminated during a disaster influences individuals’ decision-making process regarding protective actions, or mitigation behaviors. This study examined the relationship between media dependency theory, parasocial relationship, and media effects (cognitive, affective and behavioral) during the COVID-19 pandemic. A quantitative approach was used with a convenience sample. The sample focused on residents in the state of Arkansas and specific generational cohorts. The results found that the generational cohorts had different media preferences during the height of …

The Influence Of Social Capital On Risk Attitude Toward Covid-19 Amongst Traditional Undergraduates, Jordan Titera

Dissertations

This dissertation assesses the influence of the three types of social capital (bonding, bridging, and linking) on the risk attitude of traditional undergraduate students (under 25 years old who enroll directly from high school, attend full-time, and do not have major life and work responsibilities). The research is motivated by three research questions: (1) What is the risk attitude of traditional undergraduate students surveyed about COVID-19 (addicted, seeking, tolerant, averse, paranoid); (2) What are the social capital characteristics for traditional undergraduate respondents surveyed; and (3) What influence does social capital have on the risk attitude of traditional undergraduate students regarding …

The Willingness And Ability Of First Responders To Report For Duty During Disasters: A Case Study Of Local Law Enforcement Officers, William Peak

Dissertations

Role abandonment of employees is a vulnerability of first responder organizations that can be exposed when disasters occur. Organizational vulnerabilities created by role abandonment of first responders can be reduced by understanding the willingness and ability of employees to report for duty during disasters. To gain a better understanding of law enforcement organizational vulnerability to disasters, this study utilizes an online survey disseminated to police officers (n = 314) working for a police department along the Gulf Coast to determine their willingness and ability to report for duty and examines the barriers and facilitators impacting their decision to report …

Sirencide: The Impact Of Acute Stress On Emergency Vehicle Crashes, Dustin Lambert

Dissertations

Emergency services provide an invaluable service to communities and cities around the world. Research has shown these professionals encounter significant acute psychological stress throughout their work shifts. Acute stress has been shown to impact human performance in various realms, from increased risk-taking to cognitive decline. While the actual work varies between firefighters, law enforcement, and emergency medical services, a shared commonality is the operation of emergency vehicles. Emergency vehicle crashes are recognized as a serious issue by FEMA. The current work aimed to measure the impact of acute stress on emergency responders as measured by fatal emergency vehicle crashes in …

Infrastructure Risk Reduction: The Case Of Drinking Water Emergencies, Mark Paine

Dissertations

Public water systems are an integral part of community infrastructure. Drinking water contamination or service disruptions have the potential to cause economic losses, limit fire suppression capability, and result in human illnesses. Until 2016, the United States federal government had not issued a disaster declaration due to contaminated water. The first federal drinking water disaster declaration due to contaminated water serves as a sentinel event demonstrating the need to increase focus on public water systems during all phases of emergency management: mitigation, preparation, response, and recovery. Previous studies evaluating risks to vulnerable populations associated with drinking water primarily utilized qualitative …

Determinants Of Residents’ Shadow Evacuation Intention During A Hurricane In The Rio Grande Valley, Texas, Manpreet Jaiswal

Dissertations

Studies on hurricane evacuation behaviour focus primarily on why individuals do not evacuate when they are instructed to, while few examine the reasons why individuals choose to evacuate under conditions that would not require them to, termed shadow evacuation. Such behaviour might delay the timely evacuation of more at-risk coastal residents. To better understand the reasons for shadow evacuation, this study analyzes data from a household evacuation behavioural survey administered between 2012-2013 to 479 households in Cameron, Hidalgo, and Willacy Counties, Texas, known as the Rio Grande Valley. This area features a number of Colonia neighborhoods with high rates …

Cities Leading The Way: Municipal Climate Policy In The Us, Naomi Bick

Dissertations

Understanding cities is a key feature for understanding responses (or lack thereof) to a collective action problem like climate change. In the absence of federal climate change policies in the United States, many city and state governments have adopted and implemented policies to mitigate and adapt to climate change. As mayors, city managers, and city councils increasingly become central actors, scholars have shifted their studies to focus on city climate change policy (Yi et al. 2017a, Hughes 2017). Descriptive case studies have identified a broad range of factors; however, the causal mechanisms of whether cities adopt and implement climate change …

When You Play The Game Of Drones, You Win Or You Die: Examining The Role Of U.S. Drone Strikes In U.S. And English Language Allies Newspapers From 2008-2019, Melissa Aho

Dissertations

In the years following the terrorist attacks on September 11, 2001, the United States ramped up its usage of drones and drone strikes around the world. Spanning three United States’ presidents, drone strikes became a regular feature in the US military arsenal. While American newspaper media and citizens have been very pro-drone, global citizens view drones in a far more negative light. This study examines US military drone strikes and English-speaking allied newspapers in Australia, Canada, New Zealand, and the United Kingdom and evaluates if coverage remains positive or negative depending on the newspaper’s conservative or liberal leanings from 2008–2019. …

Michigan Municipal Manager Perceptions On Lgbtq+ Inclusion: A Narrative Policy Framework Case Study, Christopher R. Surfus

Dissertations

This study explores the knowledge, attitudes, and perceptions (KAP) of municipal managers regarding the LGBTQ+ community in three Michigan cities—Grand Rapids, Holland, and Kalamazoo. The purpose is to understand managers’ beliefs and attitudes towards the LGBTQ+ community and how policies are implemented and enforced to reduce discrimination. The specific research questions deal with how the beliefs and attitudes of public managers reflect an understanding of and competency on LGBTQ+ issues, how they are affected by the presence of LGBTQ+ staff members, and how they differ from the actual policy provisions affecting the LGBTQ+ community. These questions are examined in the …

The Political Economy Of American Militarism: The Military- Industrial Complex, Power Elite, And The 2003 Invasion Of Iraq, Randy S. La Prairie

Dissertations

Sociologists have paid little attention to the structural causes of American participation in wars. Consequently, the discipline offers few theoretical perspectives on American war making. Sociological theories that do exist fall under two headings: state-centric and Marxist theories. Both lack prima facie plausibility. In this dissertation, I advance a unique, alternative theoretical framework that I argue offers a more tenable theory of American militarism in the post-World War II period. The elite model of war mobilization, as I refer to it, consists of five interrelated structural causes of American participation in wars: (1) state-capitalist imperialism; (2) elite control of public …

An Inferentially Robust Look At Two Competing Explanations For The Surge In Unauthorized Migration From Central America, Nick Santos

Dissertations

The last 8 years have seen a dramatic increase in the flow of Central American apprehensions by the U.S. Border Patrol. Explanations for this surge in apprehensions have been split between two leading hypotheses. Most academic scholars, immigrant advocates, progressive media outlets, and human rights organizations identify poverty and violence (the Poverty and Violence Hypothesis) in Central America as the primary triggers responsible. In contrast, while most government officials, conservative think tanks, and the agencies that work in the immigration and border enforcement realm admit poverty and violence may underlie some decisions to migrate, they instead blame lax U.S. immigration …

Considerations For Acquiring Excess Military Equipment By Police Leaders, Michael P. Mendenhall

Dissertations

Police departments across the United States have been able to acquire excess military equipment from the 1033 program since 1997. Although several studies have examined police militarization, including the 1033 program, this is the first study that has surveyed police leaders at the local level to understand the determinants of 1033 acquisitions in Michigan. Using an open systems framework, this dissertation will examine both the internal and external factors that contribute to police leaders’ decisions to acquire or not acquire equipment for their departments. These determinants include internal factors such as budgetary considerations, perceptions of the profession, and knowledge of …

An Exploration Of The Two-Generation Approach For Single Mother Degree Or Certificate Attainment, Chiquila N. Dolison

Dissertations

Investments in student support services that encompass single mother needs can influence postsecondary degree attainment and increase earning potential that can lead to benefits, including economic self-sufficiency and poverty alleviation (Alssid et al., 2002; Gault, Milli, & Cruse, 2018; Gault, Noll, & Reichilin, 2017; Graham & Bassett, 2011; Kruvelis, Cruse, & Gault, 2017). Despite the benefits of single mothers' college degree attainment, they are least likely to earn them (Gault et al., 2018). In the United States, 8% of single mother undergraduates earn a postsecondary degree within six years of enrollment compared to the 49% of women who are not …

Water Elites’ Perceptions Of Water Security In The Middle East And North Africa Region, Ghaleb Akari

Dissertations

The Middle East and North African region continues to face significant water security challenges. The purpose of this dissertation is to gain a deeper understanding of water elites’ perceptions of water security in the MENA region. It is not meant to generalize the findings. Instead, the intention for the research is to identify, explain, and analyze by national elites' contrasting perceptions in Jordan, Iraq, Egypt, and Tunisia.

The study examines water elites’ perceptions in four areas: current knowledge level of water security, water resource management, water service delivery, and water-related risk mitigation. These elites’ perceptions of water security will help …

Barriers To Post-Secondary Success, Douglas Swanson, Najeana Henderson, Maritza Sloan

Dissertations

This study reviews factors that prior studies have identified or failed to consider as barriers to post-secondary success. The three main areas include academic success for Latinx students after high school, organizational systems and their impact on African-American students’ postsecondary readiness, and what workers think of their high school education with regards to career preparedness.

Five factors are identified as major barriers for Latinx students to continue in a higher education system. A survey of former students from Saint Louis, Missouri, and Dallas, Texas, metroplex area identified 56 Latinx students that participated in an initial survey. This led to a …

Dismantling Tools Of The Incompetent: Exploring Cultural Competence Training In Undergraduate Education Policy And Education Studies Programs, Ashley P. Allen

Dissertations

Cultural competence is described as a set of skills, values, and principles that acknowledge, respect, and work toward optimal interactions between the individual and the various cultural and ethnic groups with which an individual might come into contact. Scholars have been critical of cultural competence training because the three-dimensional approach which is its foundation fails to address institutional and systemic racism. I posit that undergraduate programs should provide training, so graduates are culturally competent entering their respective fields. I examined cultural competence training within education policy and studies undergraduate programs because these graduates will work within education at all levels …
