Examining The Association Between Fictive Kin Care, Parental Attachment And Emotional Distress In College Students, Roxanne Watts

Master's Theses

Having a supportive and secure relationship with parents can predict less emotional distress in college students. In addition to parental support, many families leverage fictive kin caregivers to provide support. This is especially true in communities of racial and ethnic minorities. The present study investigated the association between fictive kin care, parental relationships, and emotional distress in college students. One hundred fourteen (N = 114) college students completed measures that assessed parental and fictive-kin relationships, social support, and emotional distress. A COVID-19 pandemic-related distress measure was also administered. Three hypotheses were tested. First, it was hypothesized that fictive kin …

Intermittent Standing And Prior Exercise As Strategies To Prevent Arterial Stiffening That Can Arise From Prolonged Sitting, Alexander Wright

Master's Theses

Though the Great Depression and Second World War were consecutive eras and overlapped in numerous aspects, scholarship often overlooks the commonalities between these periods. To demonstrate these eras’ shared qualities, this thesis examines the relationship in emotional-cultures—the cultural norms that dictated how individuals felt and demonstrated their emotions—among Civilian Conservation Corps (CCC) enrollees and U.S. Army enlistees during WWII.

The broad intent of this undertaking is to place the cultural history of the Great Depression and WWII in conversation and to show the advantage of inter- and multidisciplinary work by applying anthropological and historical theories of emotion. Though the historical …

Assessing The Effect Of Negative Mood States On Valence-Dependent Belief Updating, Aleksandr Karnick

Master's Theses

Individuals consistently tend to underestimate the likelihood of negative events happening to them and fail to update these beliefs adequately when provided with statistical evidence. However, depressed populations are better able to accurately update beliefs. It is not clear if the ability to update beliefs effectively is due to overall dysphoria or are partially due to momentary fluctuations of acute affective states. Undergraduates (N=83) completed a belief updating task where they estimated the likelihood of a negative event happening to them, were presented with the actual likelihood of the event, and then re-estimated the likelihood of the event happening to …

The individual who endorses a GM views a challenge or failure not as a defeat and submission of inability, but a recognition that further growth, persistence, and effort are required to accomplish the desired task. This project aimed to understand more about first generation college students (FGCS) who endorse a growth mindset. Specifically, the intention of the study was to understand how …

The Impact Of Formal Education, Specialized Training, And Offense Type On Perceptions Of Employability: Can Bias Toward Hiring A Person With A Criminal History Be Mitigated?, Rheanna Standridge

Master's Theses

Gaining employment for returning citizens has been shown to reduce recidivism and contribute to a successful community reintegration. Yet, many employers remain skeptical when it comes to hiring formerly incarcerated job candidates for a variety of reasons. Though hesitations are often related to assumptions about a person’s dangerousness, there remain legitimate reasons, such as limited formal education and basic skills, that prevent returning citizens from finding work. Further, previous research suggests that hiring decisions are confounded by offense type, even if an employer would otherwise consider a person with a criminal history. Thus, it is unclear whether returning citizens’ level …

Translatina Immigrant Mental Health Wellness: Suggestive Intervention Strategies The City Of San Francisco Should Consider Adopting, Valeria Vera

Master's Theses

Translatina immigrants in the United States often suffer from intersectional traumas due to their race, gender, sexual orientation, religion, and immigration status — putting them in a vulnerable position socially, psychologically, economically, and medically. Due to their positionality in the intersections of migration, criminalization, cissexism, and mental health, they are often more marginalized and have greater needs than communities with privileged sociocultural identities. As a particularly vulnerable group, they need guaranteed access to gender-affirming healthcare that is inclusive of mental health services. Despite Translatinas’ need for mental health services, there exist many barriers making services inaccessible and insufficient in San …

Impacts Of Transit-Oriented Development Through The Eyes & Lives Of Low-Income Latinx Residents: A Case Study In Fruitvale, Oakland, Diana Saavedra

Master's Theses

Transit-oriented development (TOD) is often showcased as a solution for private vehicle dependency and growing climate issues. Although TOD seems promising, it usually has harsh, unforgiving effects such as ecological gentrification. Ecological gentrification occurs when lower-income communities, especially of color, are pushed out of their neighborhoods due to the implementation of an environmental amenity, benefit, or service. However, research suggests that TODs that apply Transportation Justice principles seem to produce more equitable results. This study explores the Fruitvale Village TOD, located in Fruitvale, Oakland, California. This TOD was selected because it is unique in its conception and implementation, as it …

Therefore, the present study explored the mediating role of psychological empowerment on the relationship between transformational leadership and the outcomes of affective organizational commitment and turnover intentions. It was hypothesized that psychological empowerment would act as a mediator between transformational leadership and affective organizational commitment and turnover intentions. Results of an online survey from 111 employed individuals showed that …

Attitudes Toward Social Activism By Professional Athletes, Aaron M. Flores

Master's Theses

Many professional athletes have raised awareness about and publicly protested social injustices. Athlete activism research has generally supported that such activism results in harsh backlash against the athletes, stemming from beliefs that politics and social justice protests do not belong in sports; patriotic/nationalistic values leading individuals to view such protests as un-American; and racial beliefs and attitudes, especially towards African American athletes. While robust, much of this research is theoretical or qualitative in nature and mainly examined reactions towards Black football players, with less focus on White athletes or those in different sports. To address these gaps, the current research …

Doppler Lidar Observations Of The Wildfire Environment: Applications For Monitoring Downslope Wind Events And Prescribed Fires, Alan C. Huston

Master's Theses

Extreme wildfire activity is often associated with downslope windstorms which cause fires to spread rapidly. To limit the potential for a utility-caused ignition, Public Safety Power Shutoffs (PSPS) can be used preemptively during predicted wind events. The timing of when winds might mix down to the surface and impact the power grid infrastructure is difficult to predict due to the interaction of the atmosphere with complex terrain. To improve the spatial and temporal accuracy of wildfire mitigation during PSPS events, the deployment of a mobile Doppler LiDAR was used to monitor the vertical structure and evolution of two downslope wind …
