Reimaging Safety After Sexual Violence: A Qualitative Exploration Of Survivors' Experiences With Formal And Informal Crisis Response Networks., Hallie Ruth Decker

Electronic Theses and Dissertations

Sexual violence (SV) is a highly prevalent public health and human rights concern impacting communities across the United States. SV is associated with a myriad of adverse physical, reproductive, sexual, mental, behavioral, financial, and social health outcomes which may be acute or chronic. Health challenges associated with post-traumatic stress and post-traumatic stress disorder are particularly common among victims and survivors of SV. Engagement in early psychological/psychosocial intervention strategies may prevent or reduce PTSD-related symptomatology after experiencing an SV encounter. Despite the availability of crisis response and support options to support individuals who have experienced SV, significant barriers exist across social …

Examining The Relationship Between Mass Incarceration, Gender Norms, And Hiv Vulnerability For Formerly-Incarcerated Black Men Who Have Sex With Men And Women., Adrienne B. Smith

Electronic Theses and Dissertations

In 2018, Black Americans represented 42% of new HIV diagnoses, despite comprising only 13% of the population. Moreover, Black men accounted for three-quarters of new HIV cases in 2016, with Black gay/bisexual men contributing to the majority of incidence among Black Americans. Existing literature suggests that individual behavior alone cannot explain these racial inequities in HIV rates. This study aims to explore the role of the criminal legal system (CLS) as a structural determinant of health, given its historical racial implications that disproportionately affect Black Americans. Additionally, the study examines masculinity’s influence as a predictor of risky sexual behavior. This …

The focal determinant of …

Phenomenological Study Of The Impact Of Stress And Burnout After Covid-19 On Educators: Supporting Teachers In Resiliency And Facilitating Adversarial Growth Post-Pandemic., Rebecca Hicks-Hawkins

Electronic Theses and Dissertations

COVID-19 has not only caused anxiety and fears among teachers for their own health and that of their families; they are also facing increased responsibility. Planning periods had been replaced with coverage periods, where teachers must teach other classes when their colleagues are out—often due to illness—because the supply of substitute teachers cannot meet the demand (Barton & Dickason, 2022). Teaching is a demanding profession, and there will always be stress associated with a job where so many external factors come into play (Hansen, 2013). However, in the face of adversity some teachers were thriving. They are showing up and …

Multimodal Stylometry: A Novel Approach For Authorship Identification., Glory O. Adebayo

Electronic Theses and Dissertations

This dissertation introduces multimodal stylometry, a novel approach to authorship identification that integrates text and source code features for a comprehensive understanding of an author's unique style.

This research aims to bridge this gap by proposing a framework that combines textual and source code data to enhance the accuracy and reliability of authorship identification. The study begins by reviewing existing literature on authorship identification and stylometry, highlighting the limitations of unimodal approaches. Leveraging recent advancements in multimodal …

Memo: Dataset And Methods For Robust Multimodal Retinal Image Registration With Large Or Small Vessel Density Differences, Chiao-Yi Wang, Faranguisse Kahki Sadrieh, Yi-Ting Shen, Shih-En Chen, Sarah Kim, Victoria Chen, Achyut Raghavendra, Dongyi Wang, Osamah Saeedi, Yang Tao

Biological and Agricultural Engineering Faculty Publications and Presentations

The measurement of retinal blood flow (RBF) in capillaries can provide a powerful biomarker for the early diagnosis and treatment of ocular diseases. However, no single modality can determine capillary flowrates with high precision. Combining erythrocyte-mediated angiography (EMA) with optical coherence tomography angiography (OCTA) has the potential to achieve this goal, as EMA can measure the absolute RBF of retinal microvasculature and OCTA can provide the structural images of capillaries. However, multimodal retinal image registration between these two modalities remains largely unexplored. To fill this gap, we establish MEMO, the first public multimodal EMA and OCTA retinal image dataset. …

The Impact Of Death Anxiety On Counselors’-In-Training Efficacy With Substance Use Populations, Jason Rose

Dissertations

Death anxiety has been an unremitting agent of the human experience. The psychological dilemma posed by the awareness and forecasting of death can increase anxiety, thus affecting well-being through the compulsive desire or will to persist (Becker, 1973; Yalom, 1980). Such psychological armor can manifest in conscious and unconscious behaviors, thoughts, and emotions to which persons utilize psychological, social, and cultural defenses to manage anxiety (Becker, 1973; Solomon et al., 2015). Across all levels of counseling, there has been a deficiency in awareness and discussion of death-related fears within the therapeutic process (Lacocque & Loeb, 1988). Therefore, due to the …

A Discrit Analysis Of Experiences Influencing Belonging For College Students With Disabilities, Paige Nichole Johnsen

Dissertations

Despite growing numbers of college students with disabilities and a call to offer support beyond disability service offices, earlier data demonstrate disproportionate barriers to disabled students’ academic success resulting from or in (a) limitations to existing accommodations, (b) worsening mental health, (c) academic achievement gaps, and (d) a privileged understanding of disability. Using disability critical race theory (DisCrit) as a theoretical framework, the purpose of this narrative case study was to discover the intersectional experiences impacting sense of belonging for college students with disabilities at a mid-sized regional institution (pseudonym: Mountain West University) in the United States. The study was …

Exploring University Student Perceptions Of Climate Change Using Connection To Nature And Psychological Distance, Jessica Duke

Dissertations

The central goal of my dissertation is to better understand undergraduate biology students’ perceptions of climate change specifically using a localized lens. Research relating to climate change perceptions and understanding is common in the K-12 setting; however, there have been far fewer studies that use undergraduate student populations. Undergraduate students represent a new age of the voting populus and are therefore an important demographic to target for inducing environmental change. To foster climate change awareness, concern, and willingness to act in our undergraduate students, we must first understand how they perceive it. Using both quantitative and qualitative approaches I explored …

Community Of Practice As A Path To An Authentic Emancipatory Education, Rachel James Beckwith

Dissertations

Beckwith, Rachel James. Community of practice as a path to an authentic emancipatory education. Published Doctor of Education dissertation, University of Northern Colorado, 2024. Emphasized in Maslow’s Hierarchy of Needs is belonging. It is identified as one of the most inherent human needs; we cannot survive without connection, without belonging. Yet our society seems to reject community values in lieu of rugged individualism. This hyper-fixation on liberty at the expense of social responsibility has not been without its consequences. Classrooms have been a prime breeding spot for the battle between “us” and “them;” the heavy emphasis on grades, contests, and …

Supply Chain Disruptions And Supplier Capital In U.S. Firms, Ernest Liu, Vladimir Smirnyagin, Aleh Tsyvinski

Cowles Foundation Discussion Papers

We empirically and quantitatively study the impact of supply chain disruptions on U.S. businesses. Leveraging granular shipment-level data on the universe of U.S. seaborne imports with nearly 200 million observations, we construct a measure of disruptions at the individual firm level for the time period 2013-2023. We document a significant heterogeneity in disruption rates among U.S. public firms, with a notable increase observed in recent years. We introduce a notion of supplier capital and investigate the effect of supply disruptions on firms’ investment decisions. In the data, firms tend to increase investment in supplier capital following the shock, however, financially …

Oxidative Phosphorylation In Melanoma Brain Metastases: A Regulator Of The Tumor Immune Landscape, Renato A. Guerrieri

Dissertations and Theses (Open Access)

Previously, we demonstrated via RNA-sequencing analysis of murine intracranial melanoma tumors that pharmacologic inhibition of oxidative phosphorylation (OXPHOS) results in increased expression of genes consistent with activated anti-tumor immune responses. The central hypothesis of this dissertation is that OXPHOS plays a critical role in the pathogenesis and immune regulation of melanoma brain metastases (MBMs).

The functional significance of OXPHOS was assessed through genetic inhibition, involving knockout (KO) of key regulatory genes such as Ppargc1a (PGC1a) and Ndfus4 (NDUFS4), a component of mitochondrial complex I. PGC1a KO in an RCAS-TVA mouse model of autochthonous lung and brain tumors developing from primary …

Jane Austen And A Biographical Study Of The Historical Narrative Process, Serena Young

Electronic Theses, Projects, and Dissertations

Jane Austen, beloved national literary icon of Great Britain, is world-renowned for her fiction. Biographers have attempted to authentically piece together her life and often, try to connect her narrative to when and how her fiction was written, as well as point out circumstances within her personal life and speculate their influence on her work. Literary analysts and critics that have examined the historical narrative process, Hayden White and Kevin Gilvary, have found that the way in which a historical account is presented plays a significant role in how history is understood and perpetuated. When examining Jane Austen’s life, many …

The Role Of Social Support And Emotional Regulation In Relationship With Adverse Childhood Experiences And Food Addiction, Negin Ghaffari

Electronic Theses, Projects, and Dissertations

Adverse childhood experiences (ACEs) are potentially traumatic experiences that occur before the age of 18 and can have long-standing impacts on mental and physical health. Individuals with high exposure to ACEs may be at increased risk for depression, substance use disorders, and cardiovascular disease (Hughes et al., 2017). Social support has been shown to play an essential role in reducing the likelihood of adverse outcomes, such as substance dependence following exposure to adverse experiences. Furthermore, emotional regulation difficulties have been shown to mediate the relationship between childhood trauma and food addiction. There has been little research on adverse events in …

Away From Keyboard: Practical Applications Of Antifascism, Amber Sarelle Easley

Electronic Theses, Projects, and Dissertations

My work sits uncomfortably between and across the disciplines of activism and art. This tension is typical of Socially Engaged Art: a social interaction proclaiming itself as art. I aim for these interactions to center antifascism in interrogating the complex interrelation between digital spaces and the streets outside our front doors, as antifascism is the only appropriate response to the blatant fascistic aspirations that is both digitally and physically present.

Relationships In Lacustrine Ecosystems: Carbon, Color, And Precipitation In North Temperate Lakes, Emma M. Squires

Environmental Studies Honors Projects

Lakes are an important part of the global carbon cycle. Carbon from terrestrial sources washes into lakes where it can be processed and then emitted to the atmosphere, buried in sediments, or make its way downstream to an ocean. During rain events, precipitation can flush dissolved organic carbon (DOC)-enriched water from the upper soil layers into lakes. As climate change causes increased precipitation totals and precipitation events in the upper Midwest, this may cause increased DOC in lakes. Increased DOC in lakes leads to increased microbial respiration, contributing to increased greenhouse gas release from lakes. Thus, it is important to …
