Design And Reliability Analysis Of A Radiation-Tolerant On-Board Computer System For Martian Surface Missions, Jack Ryan

Master's Theses

Space environments present complex challenges for electronic devices, perhaps most notably in the form of radiation effects; the natural protections provided by Earth’s atmosphere and magnetosphere are largely absent in deep space and extraterrestrial environments, making single-event effects (SEE) a critical concern. Although radiation-hardened components offer near-immunity to SEE, they possess tremendous drawbacks in both cost and performance. To circumvent such issues, this thesis investigates the feasibility of leveraging a commercial-off-the-shelf (COTS) device, the AMD KRIA K24 system-on-module (SOM), for use in Martian surface missions.

Detailed models were used to predict SEE rates in the system, and system-level fault tree …

The Link Between Incarceration And Education Level: Exploring The Correlation, Robert M. Sandoval

Electronic Theses, Projects, and Dissertations

Mass incarceration is on the rise, with education level being a strong predisposition indicator. A quantitative approach and survey method will be used to understand the correlations between the two social challenges. This research proposal is expected to reveal how education level significantly determines the probability of a person becoming incarcerated in California. A significant gap exists in understanding the intersectionality between education and mass incarceration. Intersectionality is a theory proposed by Kimberlie Crenshaw that discusses how people’s identities do not only stack on top, but also intersect to cause unique barriers. For example, Black women’s experiences with employment due …

Utilizing A Social-Ecological Approach To Understand Healthcare Professional's Ability To Identify Child Sexual Exploitation, Vanessa Gudiel, Alyssa Fierro

Electronic Theses, Projects, and Dissertations

Commercially sexually exploited children (CSEC) are an underrecognized population who face barriers when receiving healthcare services in emergency settings. A common theme that prevents them from receiving services is the healthcare professionals' (HP) inability to recognize warning signs and engage with victims. This stems from an absence of CSEC-focused curriculum in institutional settings, leading to a lack of education and confidence in identifying CSEC. CSEC screenings are not mandatory in most healthcare settings, leaving the discretion to the HP and enabling the continued missed opportunity to identify victims. The proposed study will utilize an exploratory design to conduct qualitative interviews …

Supreme Court And Presidentialism: When Judges Stand In The President’S Way, Michael Procopio Avelar

LL.M. Essays & Theses

This article examines the conditions under which constitutional courts are able to resist executive attempts at institutional capture during periods of democratic erosion. Instead of concentrating on the mechanisms through which courts are attacked, it focuses on how courts effectively behave in the long term when operating under sustained political pressure. The central claim is that judicial resistance cannot be explained solely by formal institutional design or by a general commitment to constitutional principles. It depends on the interaction of three variables: judicial replaceability, external support, and enforcement capacity.

The article develops a typology of judicial responses to executive aggrandizement, …

We Define The Future: Lived Experiences Of Foster Youth In Higher Education And The Role Of The Educational Opportunity Program, Krystalyn T. Diaz

Electronic Theses, Projects, and Dissertations

Foster youth face significant barriers to higher education, including housing instability, financial insecurity, trauma, and limited adult support, contributing to low college completion rates, with only 3 to 11 percent earning a bachelor’s degree (Morton, 2018; Moyer & Goldberg, 2019). The Educational Opportunity Program (EOP), established in 1969 within the California State University system, was designed to reduce these barriers through counseling, mentoring, financial assistance, and basic needs support. However, limited research has centered the voices of foster youth to understand their experiences with these services. Guided by Maslow’s Hierarchy of Needs and Resilience Theory, this qualitative phenomenological study explored …

Bridging Leadership Theory And Practice In University Advancement: Exploring Transactional, Transformational, And Followership Dynamics, Austin D. Quick
