The Harms Of Imprisonment And Envisioning A Desistance-Supporting ‘Good Society’, Patricia Gray, Julie Parsons

School of Law, Humanities and Social Sciences

Research evidence in the 21st century strongly indicates that prisons are inherently harmful environments in which to try to support rehabilitation, because of their destructive impact on identity, self-actualisation, mental health and social relationships. Yet HM Prison and Probation Service (HMPPS) continues to propose that prisons can be legitimate sites of rehabilitation as well as centres of punishment. This article begins by interrogating this proposition by looking at research conducted in an adult male prison. By specifically focusing on the interpersonal conflicts and tensions that the men experience in their daily lives, the research highlights the ‘relational’ and ‘self-actualising’ harms …

College Students' Perceptions Of The Student-Teacher Relationship, Lauren E. Biggs

Electronic Theses and Dissertations

Humans, as social creatures, pursue relationships with others to fulfill various needs. As such, when we enter school, we naturally seek to establish relationships with teachers, who act as significant individuals in our lives. In general, research has shown that students with close, warm relationships with their teachers tend to experience more favorable outcomes related to academic achievement, behavior, and social-emotional factors. Students with more negative relationships with their teachers conversely tend to experience poorer outcomes. Though decades of research have consistently shown this correlation, few studies have examined the relationships between college students and their professors. The current study …

Avian Communities Monitored Along A Successional Chronosequence In Bottomland Hardwood Forests In The Lower Mississippi Alluvial Valley, Eamonn Alasdair Thurmond

Electronic Theses and Dissertations

Bottomland hardwood forests in the Lower Mississippi Alluvial Valley have been extensively reduced due to agriculture conversion and altered hydrology. Remnant forests have undergone further degradation from sources such as a lack of forest management, invasive species, and reduced regeneration of oaks (Quercus spp.). Recent restoration efforts of bottomland hardwood forests have focused on implementing wildlife forestry practices that prioritize restoring wildlife habitat while retaining profitable timber harvests. In this study I surveyed bird communities in bottomland hardwood forests in the Lower Mississippi Alluvial Valley along a successional chronosequence. Birds were sampled using automated recording units over 10 days …

A Uniformly Most Powerful Test For The Mean Of A Beta Distribution, Richard Ntiamoah Kyei

Electronic Theses and Dissertations

The beta distribution is used in numerous real-world applications, including areas such as manufacturing (quality control) and analyzing patient outcomes in health care. It also plays a key role in statistical theory, including multivariate analysis of variance (MANOVA) and Bayesian statistics. It is a flexible distribution that can account for many different characteristics of real data. To our surprise, there has been very little work or discussion on performing statistical hypothesis testing for the mean when it is reasonable to assume that the population is beta distributed. Many analysts conduct traditional analyses using a t-test or nonparametric approach, try transformations, …

Real-Time Delphi Study: Perspectives Of An Autistic Panel On Independent Living, Celeste Michaud

Graduate Theses and Dissertations

The shift from institutional living to community integration for people with disabilities, including autistic people, has been significantly influenced by legislative measures and advocacy. Despite these efforts, autistic youth and adults still experience a unique transition to independent living compared to their peers with other disabilities. Studies have reported that autistic adults are more likely to remain in the family home and less likely to live independently post-high school (Anderson et al., 2014). Existing literature and legislation illustrate a fragmented approach to defining and measuring independent living for autistic adults, often driven by non-autistic perspectives (Cribb et al., 2019). This …

Quantifying Physical Function: Moving Towards A New Definition And Better Assessment, Anthony Campitelli

Graduate Theses and Dissertations

Though poor physical function (PF) and disability are two of the most impactful problems facing older adults today, the field of kinesiology has not yet devised a method of measuring PF, thus limiting investigations with the potential to lead to improved PF interventions and assessments. This dissertation aimed to develop a single, continuous measure of PF using a latent variable modeling approach, and then use the generated scores to evaluate the role of lower body muscular power in PF assessment and to construct an improved PF assessment battery for predicting overall PF.

How Others Affect Identity: The Roles Of Mere Presence, Self-Disclosure Extent, And Partner Responsiveness, Josephine Collins

Graduate Theses and Dissertations

Previous research has indicated that identity is social in nature and that close relationships strengthen sense of identity, but details of this relationship are not well understood. Self-disclosure is a vital part of close relationships; thus, the present research sought to understand how talking about oneself is at play in the relation between relationship closeness and identity. In this study, 314 emerging adults (157 dyads; Mage = 19.2) engaged in an in-person interaction with either a close other or a stranger and, within this interaction, were assigned to engage in self-disclosure or a control task. Even though the closer participants …

Supply Chains Shocks, Network Linkages, And Economic Outcomes, Romeo Eric Neuyou Nana

Graduate Theses and Dissertations

One prominent consequence of the Covid-19 pandemic was the disruption of critical parts of the global supply chain. In the U.S., delays at ports and shortages of critical inputs such as semiconductors have negative ripple effects across the economy. This situation prompts a surge of interests from academics, business leaders, and policy makers alike. However, the evidence of the quantification of supply chain disruptions’ impact and its drivers on economic variables are still scant. In this essay, I investigate the extent of the impact of supply chain shocks on the U.S. economy and the mechanisms through which they affect economic …

S&P 1500 insiders whose personal networks contained higher fractions of socially connected individuals from countries affected by early stages of COVID-19 were more likely to sell shares of their firms in the period preceding the U.S. stock market decline, and they are less …

The Impact Of Algorithmic Control And Algorithmic Management In Online Labor Platforms, Yaping Zhu

Graduate Theses and Dissertations

Online labor platforms (OLPs) are transforming the way organizations operate and how people work. Platform work has been characterized as promoting autonomy and flexibility. Workers interact with a platform rather than human managers to accomplish tasks and they have the freedom to decide when, where, and how much to work. Yet, platform workers increasingly bemoan working conditions, revealing that the expected autonomy and flexibility benefits of platform work have not materialized. Current IS research sheds light on this phenomenon by explaining that platform organizations use algorithms to manage and control workers (i.e., algorithmic control). Yet, our understanding of how algorithmic …

News Media Coverage And Framing Of Human Trafficking In The United States, Chloe Junkerman

Graduate Theses and Dissertations

This study examines what makes mainstream news media representations of human trafficking cases newsworthy, and how news media choose to frame sensationalized human trafficking stories. While there have been several notable studies examining news media framing of human trafficking as a social issue more generally, prior research has yet to empirically investigate how the news media cover specific human trafficking cases, thus overlooking what types of attributes make cases newsworthy. This is an important gap in research as the types of cases that get covered, or ignored, by news media, and how stories frame various aspects of these crimes, informs …

To Be Framed: Investigating The Influence Of American Media Frames On Gun Control, William C. Chamblee

Graduate Theses and Dissertations

Gun control may be one of the most polarizing political issues facing America today. While there are many factors that contribute to gun control controversy, one may be how it is framed by news organizations. Research suggests that the emergence of partisan news media, differing levels of issue salience, and the public’s increased willingness to selectively expose could widen the gap between both Republicans and Democrats through their opinions on the issue of gun control, causing polarization. Using a survey, this study found that both Republicans and Democrats are likely to selectively expose to partisan media outlets and that a …

Development Of A High-Throughput Screening Platform To Profile Gene Delivery And Transcriptional Control In Macrophages, Alexis Ivy

Graduate Theses and Dissertations

Macrophages are an important cell type in the body responsible for orchestrating the inflammatory response and return to homeostasis. Macrophages are often implicated in a multitude of disease pathologies including delayed wound healing, excessive fibrosis, autoimmune disease, and immunosuppression within the tumor microenvironment. Although macrophages have been targeted for therapeutic applications, success in utilizing them has remained elusive due to their relative ease of phenotype switching between inflammatory and anti-inflammatory. The challenge that remains is developing clinically relevant delivery vehicles that can target macrophages without causing a phenotypic switch counter-productive to the desired response. This is especially important when targeting …

Diversity Equity And Inclusion Education: An Evaluation Of The Safe Zone Allies Program, Shannon E. Hart

Graduate Theses and Dissertations

Diversity, Equity, and Inclusion gained unprecedented popularity from 2019 to 2022. The tide turned in 2023, and Anti-DEI legislation continues to gain momentum nationwide. This backlash may be warranted, as research demonstrates that DEI can backfire. DEI programs remain unregulated, understudied, and often paradoxically under-supported despite their potential to catalyze positive social change. Two studies were conducted to begin creating standardized, accessible, and evidence-based DEI best practices. Safe Zone Allies, a LGBTQIA+ specific DEI program was selected for program review because; (a) it was not developed hastily, (b) it was not siloed, and (c) the curriculum is evidence-based.

Cancer Heterogeneity And Mitochondrial-Targeted Therapies In Cancer Cachexia, Francielly Morena Clark

Graduate Theses and Dissertations

Cancer Cachexia (CC) is a multifactorial and complex syndrome affecting up to 80% of cancer patients and contributing to approximately 40% of cancer-related deaths. Given its relationship with patients' quality of life and prognosis, there has been increasing emphasis on understanding the underlying mechanisms of CC using pre-clinical models. However, the mechanisms of cachexia vary depending on several factors, including tumor type, model, and biological variables such as sex. RNA-sequencing technology is a crucial tool for investigating CC heterogeneity, enabling the analysis of the transcriptome across different models, conditions, and sexes using publicly available data. Aim 1 of this dissertation …

Beyond Single Connections: An Exploration Of How Overlapping Networks Drive Policy Change Among State Legislators, Melanie B. Hoskins

Graduate Theses and Dissertations

Current research on policy diffusion and innovation primarily focuses on the policy idea as the unit of analysis. While diffusion studies incorporating social network theory often examine networks at the collective entity-level, they tend to neglect the actions of individual members. This study investigates how state legislators' exposure to novel policy ideas through their multiplex network ties influences their sponsorship of related bills and how legislators’ collaboration and coordination within these networks may significantly impact public policy outcomes. This three-article dissertation addresses three key areas by: 1) examining Arkansas legislators' participation within the American Legislative Exchange Council (ALEC) network; 2) …
