Prosecutorial And Judicial Decision-Making In Federal Sovereign Citizen Cases, Kyle Kaminicki

Graduate Theses and Dissertations

This study examines how ideology and extralegal factors shape prosecutorial and judicial outcomes among sovereign citizens (“sovereigns”) compared to other terrorists accused of committing non-violent crimes in the United States. This study is informed by focal concerns theory (Steffensmeier et al. 1998), which suggests that perceptions of blameworthiness, risk, and other practical implications shape prosecutorial and judicial decision-making.

Data come from the American Terrorism Study (ATS) where several measures are used including terrorist background and other extralegal factors (age, race, gender) for sovereign citizens and terrorists affiliated with other ideologies. Data on 308 sovereign citizens indicted in 158 federal court …

The Impacts Of Incarceration On The Wellbeing Of Family Members Of African American Males Who Experience The U.S Prison System: A Phenomenological Study, Tremaine N. Leslie

Graduate Theses and Dissertations

African Americans encounter a high rate of imprisonment, and the social, economic, mental and other effects of imprisonment are extended to their families and communities (Roberts, 2004). In addition to separating individuals from their families and communities, incarceration maximizes the probability for fractured relationships, fragmented communities, and encumbers the public service systems (DeHart, Shapiro & Clone, 2018).Therefore, the purpose of this phenomenological inquiry was to explore the mental health effects of incarceration on the family members of African American males who experience the U.S prison system.

The theoretical framework utilized for this study was the critical race theory (CRT) immersed …

Perceptions Of Help-Seeking Likelihood For Depression: Examining The Relative Predictive Value Of Ethnicity And Barriers To Care, Linda Esperanza Guzman

Graduate Theses and Dissertations

Latinx and non-Latinx White adults 18 years of age and older experience depression at proportional rates. However, Latinxs seek specialized care for depression at lower rates than non-Latinx Whites, suggesting these groups experience barriers in accessing care differently. This study sought to test the theoretical steps of help-seeking as informed by the Gaining Access and Treatment Equity model (GATE model; Bridges, 2018). According to the GATE model, successful help-seeking means navigating a series of barriers: sequentially, these are perceived need, attitudinal barriers, and structural barriers. Participants (N = 987) were either Latinx (n = 437) or non-Latinx White (n = …

Barriers To Integrated Primary Care And Specialty Mental Health Services: Perspectives From Latinx And Non-Latinx White Primary Care Patients, Elizabeth A. Anastasia

Graduate Theses and Dissertations

High need, low access, and rising health care costs reveal the inadequacies of the current mental health system in the U.S. Racial/ethnic minorities, including Latinxs, face substantial disparities in accessing mental health treatment compared with non-Latinx Whites. Integrated primary care (IPC) offers an alternate model for meeting mental health needs by providing care in a way that is accessible to the general population. Though it has been suggested that IPC may reduce health disparities by decreasing barriers to mental health treatment, empirical data relevant to this question are limited. A series of three studies were conducted using a mixed methodology …

The Effect Of Breakfast Macronutrient Composition In Children Ages 7-17 Years Old As A Potential Method To Combat Childhood Obesity, Angela M. Tacinelli

Graduate Theses and Dissertations

The prevalence of childhood overweight and obesity is an ongoing concern. Currently, approximately 20% of children in the United States are obese. While obesity was once regarded merely as excessive adiposity within the body, it is has emerged as a major risk factor for chronic diseases such as metabolic syndrome, type 2 diabetes, and cardiovascular disease. Obesity is multifactorial in nature. Weight gain can result from an energy imbalance in the body due to excess energy intake (calories in) and decreased energy expenditure (calories out). Identifying methods to combat obesity is essential. Nutritional intervention may be a strategy to help …

Landscapes Of Danger: A Geospatial Analysis Of Perceived And Realistic Risk In Bryce Canyon National Park, Tia Francis

Graduate Theses and Dissertations

The quantification of risk has inspired a wide breath of literature from the physical sciences, social sciences, and interdisciplinary disciplines like geography. Many attempts to estimate risk via natural hazards either focus on quantifying realistic risk or perceived risk of lay persons, with very little overlap between these paradigms. Due to this, a considerable knowledge gap exists within perceived risk and natural hazards research. This study aims to provide a comprehensive, risk estimation and assessment strategy through a multi-hazard risk assessment of Bryce Canyon National Park (BRCA). This case study analyzed knowledge of risk among visitors with perception surveys and …

Calling Out The Trolls: Responses To Witnessing Use Of The “Troll” Label As A Defense In An Online Group Context, Dene E. M. Wamsley

Graduate Theses and Dissertations

Although the term “troll” has existed since the 1980s, its meaning has shifted in recent years as social media use has increased. People provide contrasting and imprecise definitions for what constitutes “trolling,” and often apply the term subjectively to describe online discussants who are uncivil, who are deviant, and who and present counter-attitudinal opinions. Exposure to deviance, counter-attitudinal information, and incivility often leads to unwanted psychological effects. In theory, labeling an uncivil, counter-attitudinal deviant as a “troll” proposes that their intention is to disrupt the conversation and upset other discussants, which provides a reason for why incivility is used, and …

Food Safety Risk In An Indoor Microgreen Cultivation System, Gina Marie Misra

Graduate Theses and Dissertations

Microgreens are immature sprouts of edible plants, sharing some similarities with sprouted seeds and petite leafy greens. Since they are most often grown in containers in buildings or greenhouses, they present a new area for food safety research at the intersection of the built environment and produce farming. Contamination by human pathogens has been extensively studied in other types of produce typically eaten raw, including sprouted seeds, which have been implicated in numerous outbreaks of salmonellosis over the last several decades. There is a paucity of knowledge about the microgreen sector of the fresh-cut industry; thus, it was determined that …
