Description
Women in the military work in a hypermasculine environment and may have experiences with gender microaggressions that contribute poorly to their mental health. In this quantitative study, the author assessed active duty U.S. military women’s (N = 683) reports of experiences with eight types of gender microaggressions (traditional gender roles, sexual objectification, second class citizen, sexist language, explicit threat to physical safety, implicit threat to physical safety, invalidation of sexism, and environmental; Capodilupo et al., 2010). Participants reported around a little or rarely having experiences with such microaggressions. Exploratory analyses demonstrated that Navy and junior enlisted women reported significantly higher frequencies of gender microaggressions compared to other groups. Using hierarchical regression analysis, controlling for general levels of stress, branch, rank, and sexual orientation, the author also examined whether the eight gender microaggressions explained scores on a measure of depression. Results suggested that only second class citizen explained a significant proportion of variance in depression. Therefore, the author examined whether coping style moderated the association between the gender microaggression subscales and depression as proposed. Results indicated problem focused engagement and emotion focused disengagement both moderated the link between second class citizen and depression. Findings from the current study have the potential to inform military programs, specifically around bringing awareness to subtle forms of sexism and ways to engage in coping. Limitation and directions for future research also are discussed.

Description
The transition from adolescence to young adulthood is an important developmental period, as youth experience rapid changes in many domains of their lives (Settersten & Ray, 2010). These transitions have been linked to both positive and negative turning points in youths’ behavior and psychosocial wellbeing (Elder & Shanahan, 2007). Being disengaged from work and school, two important social institutions involved in the transition to adulthood (Havighurst, 1972), has been associated with poorer mental health and increases substance use; in this literature, there is still a dearth of research among youth in the United States of America and on the developmental implications of disengagement (Hilley et al., 2019). Therefore, this dissertation includes two studies to address these gaps with respect to mental health and substance use. Study 1 explores the heterogeneity in youths’ engagement and disengagement from work and school at two developmentally relevant time points across the transition to adulthood rather than impose a priori definitions of disengagement. Next, this study explores whether risk and protective factors predict membership in these subgroups. Finally, this study examines subgroup differences in problematic substance use concurrently and longitudinally. Study 2 investigates the cross-lagged associations between opportunity youth (or youth who are neither in school nor working) status and mental health over the transition to adulthood and explores whether familial social support and socioeconomic status mitigate or exacerbate the influence of opportunity youth status on mental health. Findings from these studies support the developmental nature of disengagement (despite its heterogeneity) and its connection with mental health and substance use, as well as suggest the need for additional research into risk and protective factors.

Description
This study was designed to examine the associations between food skills, resilience, and coping during the Covid-19 pandemic. Between April and June of 2020, a sample of 154 students, faculty, and staff from Arizona State University were surveyed. Each respondent was administered a survey containing demographic questions, a food skill questionnaire, and the 14-item Resilience Scale (RS). Results indicate that food skill was correlated with resilience (p<0.001) at an r=0.364 and r2=0.1243 and that resilience was correlated with coping during the Covid-19 pandemic (p<0.001) at an r=0.455. Correlations were also run between resilience score and the separate domains of food skill score: all domains remained significantly associated with resilience score (p<0.001) with a r=0.340 and r2=0.1173 for ‘Food Selection and Planning,’ r=0.312 and r2=0.0958 for ‘Food Preparation,’ and r=0.294 and r2=0.0767 for ‘Food Safety.’ Data seems to be consistent with contemporary research suggesting positive associations between diet quality and physiological resilience and positive associations between resilience and coping during the Covid-19 pandemic.

Description
Relative to their heterosexual peers, sexual minority youth experience significant mental health disparities. This, in part, is due to prejudicial encounters (e.g., discrimination, victimization) because of their sexual minority status, and potential compounding stressors from prejudicial experiences related to their ethnic minority status, which could lead to worse mental health outcomes due to intersecting minority stress processes. Surprisingly, even though religiosity has been identified as a protective factor in the general literature for adolescents and young adults, few studies have examined whether religiosity serves as a potential buffer of the relations between stress and mental health outcomes in sexual minority Latinx youth. Thus, the goals of this study were to examine: (1) whether ethnic discrimination and sexuality discrimination have additive or interactive effects on depressive symptoms, and (2) whether self or family religiosity moderate the relations between discrimination and depressive symptoms, in a sample of 377 sexual minority Latinx youth (Mage = 20.29, SD = 2.61, age range 14-24). Results showed that there was no interactive effect between ethnic discrimination and sexuality discrimination in predicting depressive symptoms. There was a significant interaction between own religiosity and sexuality discrimination in predicting depressive symptoms, in which own religiosity was negatively associated with depressive symptoms only at low level of sexuality discrimination. No significant interaction emerged between own religiosity and ethnic discrimination. Finally, there were significant interactive effects between family religiosity and discrimination (ethnic and sexuality), in which family religiosity was negatively associated with depressive symptoms only at average and low level of discrimination. These findings highlight the importance of examining the intersection of religion, sexuality, and Latinx minority status in relation to mental health outcome.

Description
Using data from a randomized, experimental trial of a brief family-based preventive intervention for parentally-bereaved families, this study evaluated whether participation in the Family Bereavement Program (FBP) when the offspring were in childhood/adolescence (ages 8 to 16) improved competencies when the offspring were emerging/young adults (ages 23 to 32). Participants were 244 emerging/young adults; data used were from assessments at pretest, posttest, 6 years post-intervention, and 15 years post-intervention. In addition to testing the direct effects of the program, developmental cascade effects models were used to test the relations between program-induced improvements in positive parenting and decreased negative life events at posttest and subsequent effects on domains of competence and behavior problems in adolescence/emerging adulthood (ages 14 to 22) and four developmental competencies of emerging/young adulthood: academic, peer, romantic, and work competence. Results supported a cascading effects model of program effects on competence outcomes. In the full sample, there were significant mediation effects of the intervention to decreased negative life events at posttest to increased grade-point average (GPA) at the 6-year follow-up to higher academic and work competence at the 15-year follow-up. For females only, two additional significant mediational pathways of the FBP occurred. The FBP led to an increase in peer competence 6 years post-intervention, which was associated with an increase in work competence 15 years post-intervention. Also, the FBP led to a decrease in externalizing problems in adolescence/emerging adulthood, but externalizing problems were positively associated with work competence. For males, additional mediation effects of the FBP on work competence occurred. The FBP decreased negative life events. However, higher negative life events were associated with lower externalizing problems in adolescence/emerging adulthood, and externalizing problems were positively associated with work competence. For males only, a significant three-pathway mediation effect of the intervention occurred on increased positive parenting at posttest to increased romantic attachment at the 6-year follow-up to higher romantic competence at the 15-year follow-up. Peer competence showed continuity over development. Mediational analyses highlighted the role of program-induced improvements in parenting, reductions in exposure to negative life events, and earlier developmental competencies on competence outcomes in emerging/young adulthood. Implications for promoting resilience in parentally-bereaved, at-risk youth are discussed.

Description
This dissertation focuses on thermal comfort and walking as an experiential phenomenon in outdoor urban environments. The goal of the study is to provide a better understanding of the impact of psychological adaptation factors on thermal comfort. The main research questions included the impact of psychological factors on outdoor thermal comfort as well as the impact of long-term thermal perception on momentary thermal sensation. My research follows a concurrent triangulation strategy as a mixed-method approach, which consisted of a simultaneous collection and analysis of qualitative and quantitative data. Research consisted of five rounds of data collection in different locations beginning February 2018 and continuing through December 2019. During the qualitative phase, I gathered data in the form of an open-ended questionnaire but importantly, self-walking interviews where participants narrated their experience of the environment while recording one-minute long videos. The visual and audible information was first processed using thematic analysis and then further analyzed via Latent Dirichlet Allocation (LDA). During the quantitative phase, I gathered information from participants in the form of three-step survey questionnaires, that data was analyzed using T-Test regression analysis in STATA. The quantitative data helped explore and address the initial research questions, while the qualitative data helped in addressing and explaining the trends and the experiential aspects of thermal environment.
Results revealed that spatial familiarity (as a psychological adaptation factor) has a significant relationship for both overall comfort and thermal comfort within outdoor environments. Moreover, long term thermal memory influences momentary thermal sensation. The results of qualitative and quantitative data were combined, compared, and contrasted to generate new insights in the design of outdoor urban environments. The depth and breadth of the qualitative data set consisting of more than a thousand minute-long of narrated video segments along with hundreds of pages of transcribed text, demonstrated the subjective aspects of thermal comfort. This research highlights the importance of context-based and human-centric design in any evidence-based design approach for outdoor environments. The implications of the study can provide new insights not only for architects and urban designers, but also for city planners, stakeholders, public officials, and policymakers.

Description
An expanse of research has demonstrated that persons with mental illness (PWMI) tend to avoid formal psychological treatment.One possible explanation for this failure to pursue formal treatment is the tendency of religious individuals to construe mental illness as spiritual in nature, leading religious communities to actively discourage emotional and psychological help-seeking through non-spiritual means. The present study examined help-seeking behaviors among religious PWMI by examining the impact of religiosity and gender on the relationship between mental illness stigma and help-seeking behaviors. Results indicate that higher levels of perceived stigma and religious salience relate to higher reported indirect support-seeking (ISS). Moreover, only religious salience appears to significantly relate to ISS among men, whereas perceived mental illness stigma significantly predicts direct and indirect support-seeking behaviors among women.

Description
Attitudes play a fundamental role when making critical judgments and the extremity of people’s attitudes can be influenced by one’s emotions, beliefs, or past experiences and behaviors. Human attitudes and preferences are susceptible to social influence and attempts to influence or change another person’s attitudes are pervasive in all societies. Given the importance of attitudes and attitude change, the current project investigated linguistic aspects of conversations that lead to attitude change by analyzing a dataset mined from Reddit’s Change My View (Priniski & Horne, 2018). Analysis of the data was done using Natural Language Processing (NLP), specifically information density, to predict attitude change. Top posts from Reddit’s (N = 510,149) were imported and processed in Python and information density measures were computed. The results indicate that comments with higher information density are more likely to be awarded a delta and are perceived to be more persuasive.

Description
Autonomous Vehicles (AVs), or self-driving cars, are poised to have an enormous impact on the automotive industry and road transportation. While advances have been made towards the development of safe, competent autonomous vehicles, there has been inadequate attention to the control of autonomous vehicles in unanticipated situations, such as imminent crashes. Even if autonomous vehicles follow all safety measures, accidents are inevitable, and humans must trust autonomous vehicles to respond appropriately in such scenarios. It is not plausible to program autonomous vehicles with a set of rules to tackle every possible crash scenario. Instead, a possible approach is to align their decision-making capabilities with the moral priorities, values, and social motivations of trustworthy human drivers.Toward this end, this thesis contributes a simulation framework for collecting, analyzing, and replicating human driving behaviors in a variety of scenarios, including imminent crashes. Four driving scenarios in an urban traffic environment were designed in the CARLA driving simulator platform, in which simulated cars can either drive autonomously or be driven by a user via a steering wheel and pedals. These included three unavoidable crash scenarios, representing classic trolley-problem ethical dilemmas, and a scenario in which a car must be driven through a school zone, in order to examine driver prioritization of reaching a destination versus ensuring safety. Sample human driving data in CARLA was logged from the simulated car’s sensors, including the LiDAR, IMU and camera. In order to reproduce human driving behaviors in a simulated vehicle, it is necessary for the AV to be able to identify objects in the environment and evaluate the volume of their bounding boxes for prediction and planning. An object detection method was used that processes LiDAR point cloud data using the PointNet neural network architecture, analyzes RGB images via transfer learning using the Xception convolutional neural network architecture, and fuses the outputs of these two networks. This method was trained and tested on both the KITTI Vision Benchmark Suite dataset and a virtual dataset exclusively generated from CARLA. When applied to the KITTI dataset, the object detection method achieved an average classification accuracy of 96.72% and an average Intersection over Union (IoU) of 0.72, where the IoU metric compares predicted bounding boxes to those used for training.

Description
Temporal-order judgments can require integration of self-generated action-events and external sensory information. In a previous study, it was found that participants are biased to perceive one’s own action-events to occur prior to simultaneous external events. This phenomenon, named the “Egocentric Temporal Order Bias”, or ETO bias, was demonstrated as a 67% probability for participants to report self-generated events as occurring prior to simultaneous externally-determined events. These results were interpreted as supporting a feed-forward, constructive model of perception. However, the empirical data could support many potential mechanisms. The present study tests whether the ETO bias is driven by attentional differences, feed-forward predictability, or action. These findings support that participants exhibit a bias due to both feed-forward predictability and action, and a Bayesian analysis supports that these effects are quantitatively unique. Therefore, the results indicate that the ETO bias is largely driven by one’s own action, over and above feed-forward predictability.
