Dissertations

Large-scale collection of pedestrian facility (crosswalks, sidewalks, etc.) presence data is vital to the success of efforts to improve pedestrian facility management, safety analysis, and road network planning. However, this kind of data is typically not available on a large scale due to the high labor and time costs that are the result of relying on manual data collection methods. Therefore, methods for automating this process using techniques such as machine learning are currently being explored by researchers. In our work, we mainly focus on machine learning methods for the detection of crosswalks and sidewalks from both aerial and street-view …

The Role Of Pereceived Racial Discrimination On Help-Seeking Intention And Psychological Distress, Emili Noel Pickenpaugh

Dissertations

Based on their experiences of perceived discrimination, Black, Indigenous, and People of Color (BIPOC) college students should theoretically be in higher need of mental health care services as perceived discrimination often increases psychological distress. However, there is a documented disparity in the utilization of services. The Theory of Planned Behavior (TPB) suggests that those with higher levels of psychological distress should be more likely to seek services. This study analyzed the relationship between race, psychological distress, and perceived racial discrimination as predictors of help-seeking intention, specifically, with the hopes of understanding the potential moderating role perceived racial discrimination plays between …

Masculinity Ideology As A Moderator On The Effects Of Lethal Means Counseling And Distribution Of Cable Locks On Firearm Storage Practices Among National Guard Personnel, Samantha E. Daruwala

Dissertations

Safer firearm storage practices, which may reduce suicide risk, can be promoted by lethal means counseling (LMC). A recent trial found that providing a single LMC session or distributing cable locks can lead to sustained changes in firearm storage practices within a sample of firearm-owning National Guard personnel (Anestis et al., 2021). An important next step is to consider if the intervention effects may differ based on participant characteristics. One particularly relevant sociodemographic characteristic to consider is traditional masculine norms, which are evident in the military and firearm cultures and associated with several negative outcomes. The current study evaluated if …

Exploring Clinical Implications Of Consensual Non-Monogamy: A Proposed Intake Assessment Tool, Rebecca Tuttle

Dissertations

Relationships in the United States are often assumed to adhere to heteronormative and mononormative standards, which is problematic because a significant minority of individuals are neither heterosexual nor monogamous (approximately 4.5% and 4% of the United States population, respectively). As a result of mononormative biases in particular, alternatives to monogamy, such as consensually non-monogamous relationships, are often socially stigmatized and clinically pathologized. The existing research on consensually non-monogamous individuals indicates, despite negative assumptions, those who engage in consensually non-monogamous relationships demonstrate psychological well-being, physical health, and levels of relationship satisfaction comparable to their monogamous counterparts. While engaging in consensually non- …
