The findings show that older adults, individuals with chronic medical conditions, and socially disadvantaged populations continue to experience the greatest burden of disease, with social determinants of health playing an important …

Gender Differences In Streaming Service Adoption And Cancellation During Covid-19, Dylan Lewis

Florida Atlantic Undergraduate Research Journal

For over a decade, the rise of subscription-based entertainment models has appeared inevitable. This trend became even more apparent when the world went into lockdown to curb the spread of COVID-19. During this time, many people began reevaluating how they allocated their discretionary income for day-to-day purchases as the future looked bleak. The purpose of this study was to examine people’s preferences between subscription-based models and one-time purchases. To do this, a 12-question survey was conducted, and data were collected through Amazon Mechanical Turk, yielding over 195 responses. The results indicate a statistically significant relationship between age and the use …

The Effect Of Vaccine Mandates On Disease Spread: Evidence From College Covid-19 Mandates, Riley K. Acton, Wenjia Cao, Emily E. Cook, Scott A. Imberman, Michael F. Lovenheim

Research Collection School Of Economics

Nearly 700 4-year U.S. colleges mandated students receive COVID-19 vaccinations in fall 2021. Using data on college policies and county health, we estimate how mandates affect surrounding communities. Event studies from August to November 2021 show that mandates covering all colleges in a county reduced COVID-19 deaths by 5.6 per 100,000 persons, a 4.6% reduction in the U.S. total during this period. Mandates reduced COVID cases by 504 and ICU admissions by 16.2 per 100,000, though we see no statistically significant impact on hospitalizations. Impacts are larger in counties with larger college populations and low estimated ex-ante student vaccination rates.

Back To Intent: Revamping California’S Flagship Environmental Legislation And Tackling The Rise Of The “Super-Commuter”, Jordan Q. Davis

San Diego Journal of Climate & Energy Law

The passage of the California Environmental Quality Act (CEQA) in 1970 has long been considered a watershed moment in the evolution of government participation in environmental issues. In the years since, CEQA has played a pivotal role in protecting Californians’ access to the beautiful nature offered by the Golden State. However, the very regulation that has been repeatedly relied upon to breathe clean air and drink clean water may very well be an instrument upon which Californians could return to smog-ridden skies. In this regard, CEQA’s biggest vulnerability may come from a most unexpected place: its strength.

Faculty, Staff and Students Publications

Psychological stress can cause diminished immune response to infectious challenges. The extent this holds true during severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and the modifying effect of vaccination status is untested. We explored these relationships in a non-random sample standardized to the US adult population. Across 2178 participants in the Aegis study (2021-2022), we identified 507 eligible laboratory-confirmed SARS-CoV-2 infections. We estimated the natural log of nucleocapsid-binding antibody absorbance (N-antibody) at study visits up to 225 days following a positive SARS-CoV-2 test. Linear mixed effects models were fit to estimate the association of baseline perceived stress and, separately, …

Long-Covid And Cognition, Mychael Bruce

Dissertations

COVID-19 is an evolving virus that can harm the body’s respiratory and cardiovascular systems. Directly related to COVID-19 are individuals who do not recover from their initial infection, making them long haulers. Long-COVID is transitioning from a range of isolated phenomena to higher prevalence rates in patients who contracted COVID-19. Many individuals report issues with cognitive function, referred to as ‘brain fog’, that affect memory, attention, and even language skills. This literature review addresses the available research on Long-COVID and how persistent infection correlates with cognitive difficulties. It aims to explain the neurobiology of Long-COVID and how Long-COVID interacts within …

Exploring Minor Feelings: Asian And Asian American’S Racialized Emotions, Identity, And Mental Health Amidst Covid-19, Kristina Mirasol Arevalo

Dissertations, Theses, and Capstone Projects

The COVID-19 pandemic highlighted the central role of racialized emotions in shaping how Asians/Asian Americans (A/AA) experience, interpret, and respond to racism, yet these emotional processes remain underexamined in psychological research. Rather than treating emotions as outcomes of discrimination, this dissertation conceptualizes racialized emotions as dynamic processes through which structural racism is experienced, interpreted, and embodied in everyday life. This framework positions racialized emotions as a key mechanism linking racialized social contexts to identity development and mental health. Across three studies using qualitative and quantitative methods, I examine how racialized emotions shape racial meaning-making, ethnic-racial identity, and psychological well-being among …

Trust, Civic Institutions, And Crisis: A Study Of Civic Culture In Italy, Nolan Joseph Sherwood

Master's Theses

This paper examines whether cultural familism — the orientation of trust toward family at the expense of strangers and civic institutions — shapes civic institutional engagement in Italy across three levels of analysis. The first analysis links four familism indices constructed from the European Values Study (2017) to pre-COVID municipal 5 per mille tax allocation rates across approximately 7,700 Italian municipalities, finding that higher Trust Gap and Institutional Distrust robustly predict lower baseline civic giving, both nationally and within each region. The second analysis uses a Regression Discontinuity in Time design exploiting the sharp onset of COVID-19 in 2020, finding …
