The Jury Does Not Always Need Help From Lay Opinion Witnesses, Taurus Myhand

Scholarly Works

Who is the “reasonable person”? There is little doubt that every competent legal professional, both in law practice and in the academic setting, has spent a great deal of time attempting to define the reasonable person. “Reasonableness is largely a matter of common sense.” In police encounters, the definition is certainly important to the outcome of questionable police conduct. How the reasonable person is defined often determines whether a police officer has infringed on an individual’s Fourth Amendment guarantee to be secure in their person against unreasonable searches and seizures. As the narratives of the news media shape how some …

Scans, Carlos D. Leon

Master's Theses

scans is a collection of poems that explore my memories within the small farm town of Soledad, California. This collection examines the intersections of religious experiences, relationships, and core regional identifiers. I believe literature transcends time and works as a capsule for our experiences. This collection looks to examine and elevate the qualities of these experiences, inviting the reader to rediscover their own memories and the minor details lost within them. Separated into four sections, each poem works as a fragmented memory, with the intent of creating a near, complete image of their designated section. I seek to provide an …

The Iterative Process Of Developing A School-Based Intervention To Take Actions Against Racism, Lindsay Poole, Danika Perry, Zumana Noor, Kim Graham, Tia Barnes, Danielle Hatchimonji, Kira Branch

Department of Medicine Faculty Papers

Racism threatens the mental and physical health of Black and Brown K-8 students and may lead to re-occurring harm without intervention. We developed ‘Actions Against Racism’ professional development trainings using a trauma-informed racial socialization lens to provide K-8 educators with proactive strategies to disrupt the negative psychosocial developmental outcomes associated with racism. This paper is a descriptive account of how we iteratively developed this intervention through four phases over the course of four years. The primary takeaway from this work is that developing and implementing interventions to disrupt racism and promote healing must take into account the implementation context, with …

Utilizing Technology To Support Collaborative Problem-Solving Of K-12 Students In Stem Education: A Multivariate Multi-Level Meta-Analysis, Marzieh Dehghan-Chaleshtori

Electronic Theses & Dissertations (2024 - present)

As classrooms in the 21st -century increasingly incorporate digital tools, educators and researchers have turned their attention to the promising potential of technology in enhancing essential competencies such as collaborative problem-solving (CPS) skills (OECD, 2017). CPS skills, including joint decision-making and coordinated problem resolution, are necessary for success in both academic and real-world contexts. While many studies have investigated individual problem-solving in technology-enhanced learning environments, the collaborative dimension remains underexplored (Graesser et al. 2018b). This dissertation addresses that gap by conducting a multivariate multi-level meta-analysis to examine the overall effects of technology use on K–12 students’ CPS skills in STEM …

Self-Preservation: Autobiography As A Form Of Archivization As Seen Through The Life And Poetic Works Of John Clare, Meghan J. Slaff

Electronic Theses & Dissertations (2024 - present)

This paper will look at how the processing efforts of an archivist mirror that of an autobiographer through the shared motivation of adding to the cultural memory or textual canon of a society. For archival purposes, the typical steps of ingesting, preparing, and presenting a collection are creation, capture, arrangement/description, and pluralization. To create an autobiography, writers take the memories that have been created and experienced due to events in their lives and capture those memories via recording in the literary form known as autobiography. These autobiographers then arrange and describe their memories in a way that shows vast similarities …

Multimorbidity In Adolescents: The Longitudinal Impact Of Childhood Socioeconomic Trajectories And Health Risk In Adulthood, Savitha Sambandamoorthy

Electronic Theses & Dissertations (2024 - present)

Abstract

Background:

Multimorbidity, defined as the co-occurrence of two or more health conditions (physical, mental, or both), has been thought of as a disease of the elderly, with most studies of multimorbidity focusing on adults and the elderly population. However, co-occurring (multimorbid) health conditions are common in adolescence, and it is important to understand the profiles and patterns of multimorbidity during adolescence, a critical developmental period with long-term implications. Social determinants of health, especially lower socioeconomic status (SES), are linked to higher risk of multimorbidity and poor outcomes in adulthood. However, most of the past studies that have looked at …

Mythogenesis In As I Lay Dying: A Comparative Exploration Of Mythmaking And Counter-Myths, Allison K. Groupp

Electronic Theses & Dissertations (2024 - present)

This thesis explores William Faulkner’s As I Lay Dying through the lens of comparative mythology, arguing that the novel constructs a counter-myth that challenges dominant Western narratives. By engaging with non-Western mythological traditions—particularly Proto-Indo European, Hindu, and Indigenous cosmologies—the study reveals how Faulkner embeds symbolic structures that transcend Christian and Greco-Roman frameworks. Using semiology and structuralist frameworks developed by Ferdinand de Saussure, Claude Lévi-Strauss, and Roland Barthes, the analysis deciphers a mythopoetic narrative that refocuses marginalized myths to destabilize binary oppositions such as Christian/Pagan, civilized/uncivilized, and male creation myths with female creation myths. Each chapter examines a different mythic layer: …

Kafka In The Plague Years: Reinterpreting Absurdity In The 2020s, Chris Lownie

Electronic Theses & Dissertations (2024 - present)

No word better encapsulates the confusion and inequality proliferating in the post-2020 global world than “absurd.” Absurdity consumes the way we interact with one another, going about life-as-usual in pocket worlds in which the individual is alienated from both oneself and others. Life is defined by a series of problems that regularly go ignored by both institution and general populace alike, but not by the human body: the effects of sustained illness and reinfection by recurrent viruses in a world that no longer acknowledges their severity nor their pervasiveness nor steps we may take towards personal safety. Daily life has …

Understanding The Dynamical Mechanisms Governing Northern Hemisphere Wintertime Persistent Flow Regimes And Their Associated Extreme Weather Events, Tyler Christopher Leicht

Electronic Theses & Dissertations (2024 - present)

Weather regimes are characterized as patterns of low-frequency variability in the middle to upper troposphere of the extratropics. Weather regimes can also be linked to variations in surface weather, making the study of weather regimes a bridge between traditional synoptic-dynamic meteorology and subseasonal-to-seasonal variability. This dissertation identifies and categorizes persistent flow regimes (PFRs), analyzes the dynamics underpinning PFR formation, identifies the linkages to atmospheric teleconnections, and examines the occurrence of surface weather extremes before and during PFRs.

PFRs are identified from 1979–2022 and grouped into five clusters using k-means clustering, which then allows for time-lag composite analysis to determine the …

The Multifaceted Role Of Glutamate At Excitatory And Inhibitory Synapses, Maurice A. Petroccione

Electronic Theses & Dissertations (2024 - present)

Our thoughts, memories, and actions are finely controlled by the coordinated activity of neural circuits in the brain. Prior work has identified a multitude of molecular mechanisms that contribute to the generation of these higher order functions, yet we know very little about how our ability to learn and perform habitual actions change depending on how far neurotransmitters released from neurons can travel away from their point of release. This is the main focus of my work, which I carried out using a diverse toolbox and focusing on two brain regions: the hippocampus and the striatum. The hippocampus controls learning …

Essays On Innovation And Labor Market Benefits, Kyoungah Noh

Electronic Theses & Dissertations (2024 - present)

The first chapter examines the impact of bank failures on team-based innovation, focusing on the persistence of inventor teams under credit supply constraints. Using U.S. patent and FDIC data from 2000 to 2012, this paper presents three main findings. First, bank failures significantly reduce both the number of team patents and the number of inventors with collaborators. Second, negative banking shocks decrease the likelihood that inventor teams remain together for projects in subsequent periods. However, team-specific factors, including geographic proximity, prior collaboration experience, and smaller team sizes, mitigate the adverse effects of bank failures and help preserve the stability of …

Epithelial Responses And Remodeling In The Submandibular Gland Post-Irradiation, Victoria Gellatly
