Juror Perceptions Of Interview Quality From Child Victims With Autism, Megan Blackburn

Theses and Dissertations

Autism Spectrum Disorder (ASD) can affect multiple memory abilities, including episodic memory, source monitoring, and relational processing. The possibility of these memory deficits can affect how a child with ASD testifies in court if they are the victim or witness to a crime. These testimonies are especially crucial for Child Sexual Abuse (CSA) cases where one of the biggest challenges is the lack of physical evidence in most cases, which leads to an abundance of trials relying on the initial forensic interview with the victim and victim testimony. Due to this, and the increased chance of affected memory abilities, it …

Mountain Lions In North Dakota: A Public Opinion Survey, Theodore A. Darnell

Theses and Dissertations

Breeding mountain lion (Puma concolor) populations currently inhabit the western portion of North Dakota. In recent years, apparent increases in human-lion interactions across North Dakota, and other Midwest states, have challenged wildlife managers who strive to balance biological and social carrying capacities of these animals.

A Critical Race Examination Of The Lived Experiences Of Persistent African American Students At A Predominantly White Community College, Elena Favela Naca

Theses and Dissertations

For well over a century, African Americans have fought for equal rights to employment, prosperity, political power and freedom. Earning an education was the way forward. Over time, legislative and institutional policies have created greater access to education for racialized individuals. Yet, African American students remain the most underserved population, and among the lowest in degree attainment across ethnic groups. Decades of research literature places blame on students and families, highlighting student deficiencies. Far fewer explanations in the literature point to institutional barriers that perpetuate practices that place African American students at a disadvantage. Critical Race Theory (CRT) offers a …

Safety Culture In Collegiate Aviation: A Cross-Sectional Analysis Between Multiple Universities, Robert Foster

Theses and Dissertations

A concurrent-embedded mixed method was used to evaluate observed outcomes of safety culture among multiple collegiate aviation programs in the U.S. A hypothesized model that measures the relationships between scales of safety management systems (SMS), safety motivation (mediator), and safety behaviors (safety compliance, safety reporting, and safety participation) was assessed using structural equation modeling/path analysis (SEM/PA). Demographic differences in safety culture were also evaluated. Semi-structured interviews were used further to understand the impacts of SMS on safety culture. Findings suggest significant predictive relationships between SMS and observed safety culture outcomes. There was also a significant mediation role of safety motivation …

The Impact Of Clinician Attachment Style On Burnout And Job Satisfaction: Introducing Mindfulness As A Mediator, Jill Marie Calderon

Transitions In Tumultuous Times: Teachers’ Experiences With Distance Learning Amidst The Covid-19 Pandemic, Lisa Ross-Hain

Theses and Dissertations

The COVID-19 pandemic in the spring of 2020 prompted the first nationwide extended educational disruption, resulting in many challenges for teachers as they were forced to a distance teaching and learning model. Educators modified curricular content, delivery, and assessment methods to accommodate and engage learners and maintain academic expectations while at the same time attempting to mitigate undue stress for their students. Teachers met this task with little to no adaptive expertise to draw from, as few had previous experience with distance teaching. Constructivist theory guided this qualitative study exploring teachers’ experiences in distance learning through a lens of adaptive …

The Effects Of Modulating Accommodative-Vergence Stress Within The Context Of Operator Performance On Automated System Tasks, Kyle Anthony Bernhardt

Theses and Dissertations

Automated systems (e.g., self-driving cars, autopilot) can reduce an operator’s (i.e., driver, pilot, baggage screener) task engagement, which can result in mind wandering, distraction, and loss of concentration. Consequently, unfavorable performance outcomes, such as missed critical signals and slow responses to emergency events, can occur. Because automation reverts the operator to a “visual monitoring” role, the oculomotor accommodative-vergence responses (the oculomotor responses that maintain a single focused image on the retina) may play a vital role in human-automation interactions. Prior research has shown that individuals with deficits in the accommodative-vergence responses can exhibit inattentive symptoms (e.g., poor concentration) characteristic of …

Asexual Experiences Of Microaggressions Scale: Instrument Development And Evaluation, Evelyn Estela Ayala

Theses and Dissertations

The present paper explores the experience of microaggressions among asexuals and relevant literature. There is a dearth of research on asexuality, particularly as it relates to the experience of microaggressions. However, research suggests that microaggressions have a cumulative impact on both physical and emotional well-being as reported by all minority groups that face microaggressions (Lewis, 2009, Mayer, 2010). The development of a scale that measures the experience of microaggressions would allow for this area of research to be further studied. The paper utilized DeVellis’s (2017) method for scale development to develop a psychometrically sound scale assessing the experience of microaggressions …

Predictors Of Professional Quality Of Life In Rural Nurses, Stephanie Deese

Theses and Dissertations

Worldwide nursing shortages have led to an increased burden on healthcare systems, and this is especially true in already underserved, remote, and rural areas, where access to healthcare is limited and the loss of highly-skilled nursing professionals is deeply-felt. Professional quality of life (ProQOL) has been studied as a major influence on nurses’ wellbeing, job satisfaction, burnout rates, turnover rates, and quality of care. While certain job-related factors that impact nurses’ ProQOL outcomes have been identified – excessive workload, exposure to trauma, financial strain due to low wages, lack of or over-emotional engagement in the workplace, individual disposition – certain …

Sexism, Gender Identity, And Psychological Well-Being: Examining Women’S Reactions To A Social Identity Threat, Wendy Nicole Fisher

Theses and Dissertations

For women, sexism is an unavoidable experience and perceiving one’s self as a victim of sexism can have detrimental effects on psychological well-being. However, situational factors, such as level of sexism, and individual differences in gender-related beliefs can influence whether women attribute negative experiences and outcomes to sexism and the degree to which they are impacted by sexism. The current two-part study examined how women responded to sexist feedback depending on the level and target of sexism, as well as individual differences in gender identity and endorsement of sexism. The impact of sexist feedback on women’s psychological well-being was also …

An Investigation Of Loss Of Control Eating Episodes And The Five Indicator Variables Of Loss Of Control Eating In A Non-Clinical Sample, Erica Goodman

Theses and Dissertations

Binge eating is common across both clinical and non-clinical populations; the diagnostic definition of binge eating has been scrutinized by extant literature in that findings have shown loss of control (LOC) to be more related to pathology than the amount of food consumed. The current study aimed to elucidate this notion further by investigating different types of LOC eating based on perception and amount of food consumed. College students (N = 227) completed self-report questionnaires assessing disordered eating, psychopathology, emotion regulation, impulsivity, quality of life, and self-esteem; 173 (76%) also completed an interview on typical and LOC eating in the …

An Examination Of The Short- And Longer-Term Reciprocal Relationship Between Older Adults' Cognitive Reappraisal And Positive Emotions And Their Impact On Psychological Well-Being, Nicole Haverstock

Theses and Dissertations

Older adults face many age-related challenges, making it critical to identify malleable coping strategies that contribute to more frequent positive emotions and serve to protect overall psychological well-being. Prior research has shown that cognitive reappraisal, or finding meaning in a difficult situation, is a cognitively-based coping strategy that contributes to more frequent positive emotions. The current studies examined the short- and longer-term reciprocal relationship between engagement in cognitive reappraisal and frequency of positive emotions using a cross-lagged panel design. Multiple indices of psychological well-being were also assessed (i.e., perceived control, life satisfaction, self-efficacy, perceived stress, and depressive symptoms). Study 1 …

Understanding Well-Being Among Black Female Student Activists Attending Predominantly White Institutions: A Narrative Inquiry Approach, Stephen Grey

Theses and Dissertations

As engagement in activism continues to increase on campus and nationally, a paucity of research exists on the experiences of Black student activists attending PWI and their well-being. Narrative inquiry was utilized in this study to better understand the lived experiences of two Black student activists. Semi-structured interviews were conducted with both participants to gain in-depth narratives of their experiences engaging in activism on PWIs. A narrative thematic approach was used to analyze the results. The findings suggested that the Black student participants experienced benefits (increased sense of belonging and racial cohesion) and consequences (activist burnout and decreased academic performance) …

Online Comment Incivility And Its Impact On Social Perceptions Of Stalking, Abigail Marie Kroke

Theses and Dissertations

The current study focuses on stalking and will enable a better understanding of how stalking is perceived. There are two main study objectives: to examine social perceptions of an online disclosure by a target of stalking behavior and to examine the role of online incivility on mood and social perceptions of stalking. Overall, both men and women responded similarly to the stalking scenario. Participants expressed …

Auditory Consonant Trigrams: Construct And Criterion Validity Update, Katharine Elizabeth Lindberg

Theses and Dissertations

The Auditory Consonant Trigrams (ACT) has historically been used in research and clinical settings as a measure of working memory ability, though previous research has failed to identify the precise cognitive processes and abilities measured by the task. The ACT total score (ACT T) has been shown to be sensitive to numerous clinical neurological and psychological populations (i.e., TBI, ADHD, MS, MDD). Alternatively, little is known about the ACT perseveration score (ACT P), the current study aimed to identity the ACT T and ACT P’s relationships to other neuropsychological measures and their clinical utility within diverse clinical/neurological presentations. In a …

Maladjustment Correlates Associated With Sexual Perpetration Tactics, Katya Maureen Mickelson

Theses and Dissertations

This project completed a partial replication and extension of a prior study (Norton-Baker, Russell, & King, 2018) regarding tactical differences in sexual perpetration victimization strategies. Respondents (n = 559) completed the Revised Sexual Experiences Survey-Long Form Perpetrator (SES-LFP) before being assigned to different macro-tactical groups (i.e. Non-Violent, Coercive, Aggressive, Polytactic). Membership to groups of micro-tactics of sexual perpetration was then assigned (sexual harassment, non-consensual distribution of sexual content, voyeurism, exhibitionism, sexual coercion, sexual coercion facilitated by substances, sexual perpetration, sexual perpetration facilitated by substances, and multiparticipant offenders). Participants completed the PID-5 as well as other measures of maladjustment. Polytactic perpetrators …
