Child Sexual Abuse Disclosure: Non-Offending Fathers, Mckayla Marie Harrison

Dissertations

Rates of childhood sexual abuse (CSA) are difficult to track due to the taboo nature and stigma surrounding the topic (McElvaney & Nixon, 2020). To address this nationwide crisis, mental health clinicians are relied upon to educate, assess, and treat accordingly. Yet, despite the ubiquitous nature of CSA, existing research has not yet examined non-offending fathers’ experience, a major support system and means of healing for children. This qualitative phenomenological study sought to capture the descriptions of non-offending fathers with children that have disclosed sexual abuse in an effort to better understand the struggles and needs for these fathers, as …

Counseling Students’ Experiences Of Religious/Spiritual Transitions: A Narrative Inquiry, Lexi Gene Heringer Wimmer

Dissertations

Religious and spiritual (R/S) identities are not stagnant constructs, as may often be believed (Strawn, 2019). The landscape of religion and spirituality is shifting rapidly, and these changes point to individual experiences of R/S transition. One place these kinds of individual changes are occurring is within counselor training. Counselor training can be a transformative experience, and these transformations can include religious and spiritual changes (Nogueiras et al., 2019). Little research explores a broad understanding of religious/spiritual transition, and this gap widens when considering counselors-in-training (CITs) specifically. The purpose of this narrative inquiry was to more fully understand the narratives of …

Design, Synthesis, And Optimization Of Allosteric Inhibitors Of Hiv-1 Integrase, Krunal H. Patel

Dissertations

The human immunodeficiency virus type 1 (HIV-1) infection remains a global health crisis, necessitating the development of innovative antiviral strategies. During the integration step, HIV-1 integrase (IN) interacts with viral DNA and the cellular cofactor LEDGF/p75 to effectively integrate the reverse transcript into the host chromatin. Recently, a novel class of antiretroviral agents called Allosteric Inhibitors of HIV-1 Integrase (ALLINI) compounds has emerged as a promising avenue in the fight against HIV-1. While originally designed to inhibit IN-LEDGF/p75 interactions, these compounds have been shown to also impact late-stage viral maturation severely through IN multimerization. Induction of IN multimerization interferes with …

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.

Comparison Of Bayesian Versus Maximum Likelihood Estimation In The Case Of Unbalanced Panels With Count Data, Bryan Hudson

Dissertations

Commonly in applied research settings, investigators wish to study counts of some event of interest over time, such as number of infections, or absences from school. However, in many cases, investigators may only have access to data sets in which measurements with individuals are not available at each measurement timepoint. A foundational statistical method for the study of panel data is generalized linear mixed effect modeling, which typically uses the maximum likelihood estimation (MLE) to estimate parameters. However, Bayesian estimation (BE) offers an alternative approach. In this simulation study, data were generated with varying sample sizes, proportions of missing data, …

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 …
