Investigating The "Tend-And-Befriend" Stress Response As A Risk Factor For Sexual Victimization Among College Women, Emily Kathleen Presutti

Theses - ALL

Sexual victimization of college women is a significant public health concern on U.S. college campuses. Traditional research on the human stress response has focused on the "fight-or-flight" model, which may not adequately capture female-typical responses in stress-inducing situations. Using a mixed-methods design, we sought to determine whether the "tend-and-befriend" stress response serves as a potential correlate of sexual victimization among college women and examine whether it contributes additional variance beyond established correlates of sexual victimization such as alcohol use, history of sexual victimization, and involvement in campus party culture. The study was conducted in two phases. In Phase I, 128 …

Policies Of Pain: Neoliberal Rhetorics Of The Opioid Epidemic In Culture And Policy, Gina Arlene Stinnett

Dissertations - ALL

This dissertation outlines and examines the Neoliberal rhetorics of choice and responsibility, and how these rhetorics are utilized in policy and culture related to the Opioid Epidemic in the United States. Through this examination of neoliberal rhetorics in policy and culture, I unpack the circular influence these two have on each other—i.e., cultural assumptions inform policy decisions, and established policy can slowly influence cultural assumptions. The key area in which these two influence each other is through rhetoric, therefore I argue that in addition to an economic and cultural structure, neoliberalism is a rhetorical structure—it shapes our society specifically through …

Essays On Housing Choices, Neighborhood Quality, And Urban Blight, Samuel Saltmarsh

Dissertations - ALL

This dissertation contains two chapters related to housing choices of low-income families, neighborhood quality, and the remediation of urban blight. The first chapter examines the effectiveness of Detroit's 2014–2022 residential demolition program in addressing neighborhood blight and vacancy in a shrinking city context. Using a stylized model of durable housing with downward price frictions, I combine parcel-level data on vacancies, blight, and demolitions to estimate the causal effects of demolition exposure on vacancy rates for non-demolished, single-family homes. Employing a difference-in-differences design, I find that the program as a whole did not reduce vacancies, and instead slightly increased them by …

Exploring The Chemical And Biological Foundations Of Protein Lipidation Through Functional And Computational Studies, Andrea Sprague-Getsy

Dissertations - ALL

Post-translational modifications (PTMs) are essential for the diversification of the human proteome. Prenylation is a PTM defined by the addition of a 15-carbon or 20 carbon isoprenoid group by FTase and GGTase-I, respectively, onto a cysteine near the C-terminus of proteins. This modification is the first step within the prenylation pathway where proteolysis and carboxymethylation occur afterwards, aiding in proteins localization to the cellular membrane. These prenyltransferases canonically recognize a “CaaX” box motif which has been determined through biochemical and structural studies. Recently, sequences following the C(x)3X and Cxx patterns have been shown to be prenylated as well as an …

On Detecting Change-Points Of A Segmented Logistic Regression Model, Jingwen Li

Dissertations - ALL

This dissertation investigates the problem of change-point detection in segmented logistic regression models, where the total number of change-points is unknown. We consider both unconstrained models, which allow discontinuities at change-points, and constrained models, which impose continuity across change-points. The central challenge is to determine the number of change-points and to accurately estimate their locations, while ensuring valid statistical inference for the associated regression coefficients. We begin by introducing a set of regularity assumptions that underlie the theoretical analysis throughout this work. For a given number of change-points, we present algorithms to estimate their locations and obtain the maximum likelihood …

Three Essays On The Supplemental Nutrition Assistance Program (Snap): Examining External Shocks, Protective Effects, And Administrative Challenges, Hyojeong Kim

Dissertations - ALL

Abstract In this dissertation, I present three studies that examine how different forms of inconsistency—arising from timing disruptions, eligibility structures, and administrative churn—shape the functioning and effectiveness of the Supplemental Nutrition Assistance Program (SNAP). Although SNAP is designed to provide a reliable source of food assistance, access to benefits is not always predictable, continuous, or evenly accessible. The studies show that inconsistencies can emerge through external shocks that alter the timing of benefit delivery, through eligibility rules tied to disability determinations in other programs that may exclude self-reported disabled households from accommodations, and through administrative procedures that generate temporary interruptions …
