The Combined Role Of Sexual Selection And Socioeconomic Environment In Explaining Everyday Risk-Taking Behavior In Human Males, Hannah Goodman, Cyril C. Grueter, David A. Coall

Research outputs 2022 to 2026

Sexual selection theory predicts that males, especially in their prime reproductive years, are more risk-prone than females. Risk-taking is a means to convey mate quality or “good genes” to members of the opposite sex or competitive ability to members of the same sex. Therefore, risk-taking should be more common in the presence of potential mates (intersexual selection or female choice) or in the presence of male competitors (intrasexual selection or male–male competition). Risk-taking can also be situated within a life history/ecological perspective, according to which environmental unpredictability promotes more present-oriented and risky behavioral strategies. Therefore, people living in areas of …

Case Report: Disseminated Herpes Simplex Virus Complicated By Hemophagocytic Lymphohistiocytosis In A Neonate, Nicholas Tadros, Nihal Godiwala

School of Medicine Faculty Publications

Neonatal herpes simplex virus (HSV) infection carries a high mortality rate due to its potential to cause disseminated disease involving multiple organ systems, which can rapidly progress to shock and death if not promptly treated. In rare cases, neonates may mount an uncontrolled inflammatory response leading to hemophagocytic lymphohistiocytosis (HLH), a severe hyperinflammatory syndrome. We present a case of neonatal HSV infection complicated by HLH, highlighting the challenges of managing both conditions concurrently. Our therapeutic approach demonstrated a reduction in systemic inflammation and viral load; however, despite these efforts, the patient developed multiorgan failure and ultimately died from the initial …

Time And Flesh: Exploring The Embodied Experiences Of Black Mothers, Amber Tucker

Social and Cultural Sciences Faculty Research and Publications

Drawing on Black feminist theories of intersectionality and concepts of temporality and embodiment, this study centers Black girlhood to understand Black girls embodied journeys of “becoming” Black women. Findings revealed that: (a) Black girls often have complicated histories that lead to constrained and liberatory choices in adulthood and motherhood; (b) becoming a Black woman involves continual adaptations to temporal and historical contexts; and (c) Black motherhood is a contested space, deeply shaped by remembering Black girlhood and navigating maternal responses to legacies of harm. This study highlights the challenges and strengths in the transitory states of Black womanhood.

Buried Identities: Addie Bundren And The Vanishing Rural South, Eleanor Smith

FCRH Honors Program Theses

As I Lay Dying, by William Faulkner, was published in 1930 and follows the Bundrens, a poor white farming family, as they transport Addie Bundren’s body across the county to be buried with her kin in the town of Jefferson. Telling the story of a literal journey from the minimally developed countryside to the seat of Yoknapatawpha County, the novel shows how the Bundrens confront modernization, an encounter mediated through the female body of their matriarch. While existing scholarship on As I Lay Dying often emphasizes themes of gender and modernity, few studies apply the thesis advanced by some historians …

Introduction: Deep brain stimulation (DBS) is a promising treatment for refractory depression, utilizing surgically implanted electrodes to stimulate specific anatomical targets within the brain. However, limitations of patient-reported and clinician-administered mood assessments pose obstacles in evaluating DBS treatment efficacy. In this study, we investigated whether an affective bias task, which leverages the inherent negative interpretation bias seen in individuals with depression, could serve as a reliable measure of mood changes during DBS therapy in patients with treatment-resistant depression.

Methods: Two cohorts of patients (n = 8, n = 2) undergoing DBS for treatment-resistant depression at different academic medical centers …

Intraocular Lens Power Calculation In Challenging Cases, Jack X Ma, Li Wang, Douglas D Koch

Faculty, Staff and Students Publications

In this article, we reviewed recently published papers of intraocular lens (IOL) power calculation in special eyes. In short eyes, accurate estimation of effective lens position is critical, and the ZEISS artificial intelligence IOL calculator produces the best outcomes. In long eyes, accuracy has been improved with axial length (AL) adjusted formulas such as the Wang-Koch AL adjustment and newer IOL formulas. In keratoconic eyes, hyperopic refractive outcomes increase with steeper keratometric values, and accuracy is poor in eyes with keratometric values ≥50.0 D. Two keratoconus-specific formulas (Barrett True K for keratoconus and Kane keratoconus) have been introduced. In eyes …

High Tumor Cd161 Expression Predicts A Survival Advantage And Marks A Th1-Skewed Microenvironment, Briana Amicarella Burns, Manasvi Chandra, Vanaja Konduri, William K Decker

Faculty, Staff and Students Publications

CD8+CD161+ T-cells exhibit augmented memory and cytolytic properties, mediating enhanced immunity in murine tumor models and improved survival in human non-small cell lung cancer. This T-cell subset might serve as a biomarker of positive response to therapy or even be isolated to augment current immunotherapeutic approaches yet limited knowledge of CD161 expression in human cancers restricts practical application. Here we bioinformatically tested the hypothesis that CD161 expression may be associated with positive outcomes in human cancers and investigated mechanisms underlying any observed advantages. Using TCGA-PANCAN dataset, we analyzed expression of CD161 in over 10,000 human tumors, correlating expression levels with …

Of Monsters And Men: Fantasy, Aesthetics, And The Nation In Pan's Labyrinth (2006) And The Shape Of Water (2017), Ally Fleming

Scripps Senior Theses

ABSTRACT: Guillermo del Toro has established himself as one of Hollywood’s most beloved filmmakers due to his ability to blend popular genres with arthouse flair. This is especially true when it comes to fairy tales, a common thread woven throughout his films that are consistently imbued with political commentary on authoritarianism. This is most apparent in two of his most critically acclaimed films, Pan’s Labyrinth (2006) and The Shape of Water (2017). Part of why these films are so beloved is how they utilize popular culture not just as tools to foreground the story’s setting, but also to guide the …

The Moral Justifications Of The Justice-Experienced: Recidivism In Dark Triadic Morally Disengaging Offenders, Lacy Parrett

Scripps Senior Theses

Little is known about the cognitions of those who commit violent crimes; even less is known about the justification process of those who reoffend after completing a prison sentence. The proposed study suggests analyzing the moral disengagement strategies and personality traits of incarcerated adults to identify recidivism risk factors. Current literature indicates that nonhomicide violent offenders’ use of moral disengagement cognitions that justify the violation of socially accepted morals will moderate the relationship between psychopathic, Machiavellian, and narcissistic personality traits and offenders’ risks of recidivating. Furthermore, it is anticipated that an interaction will exist between moral disengagement and this so-called …

Price Sensitivity In The Secondhand Market: An Analysis Of Consumer Behavior On Ebay, Reyna Kleemeier

Scripps Senior Theses

The secondhand market is rapidly expanding, driven by growing consumer interest in sustainable consumption and economic value. This thesis examines consumer price sensitivity within the online resale market. Using a unique dataset of eBay clothing transactions, I employ an OLS regression model to analyze price elasticity of demand across various categories of new and used goods. I find that used goods exhibit characteristics of Veblen goods, where higher prices correlate with increased demand, suggesting that consumers perceive elevated prices as signals of rarity, quality, or exclusivity. My results highlight the nuanced dynamics of online resale markets, where consumer behavior is …

Empowering Adolescent Females: A Psychological Approach To Sexual Education, Paola Rausseo

Convinced Or Pressured: Investigating The Effect Of Self-Esteem Levels And Majority Opinion Size On Jurors Conformity In Deliberations, Mia Draisin

Scripps Senior Theses

Conformity has been shown to influence decision-making due to informational (knowledge seeking) and normative (social pressure) influence. Majority size is also related to conforming tendencies. In addition, self-esteem has been found to have a relationship with conformity. Individuals with low self-esteem have a fear of social rejection and partake in conforming behaviors. This study will illuminate the juror decision-making process and how external factors impair jurors' impartiality. This study will investigate how a juror's self-esteem level and the size of the majority opinion influence their likelihood of conforming during deliberations. It is hypothesized that individuals will be more likely to …
