Successful Psychopathy: Trait Expression, Construct Validity, And Career Differences Among Lawyers, Law Students, And Pre-Law Undergraduate Students, Jessica Rush

Student Theses

Psychopathy is a multidimensional personality construct traditionally studied in offender populations but increasingly recognized in high-functioning, nonclinical groups. This study examined the expression of psychopathic traits—Fearless Dominance, Self-Centered Impulsivity, and Coldheartedness—among legal professionals at various career stages, including pre-law students, law students, and practicing attorneys. Using the Psychopathic Personality Inventory–Revised (PPI-R) alongside validated measures of related constructs (e.g., narcissism, aggression, affect, behavioral activation/inhibition), the study assessed trait distribution, construct validity, and contextual influences in a sample of 82 participants. Results provided partial support for the PPI-R’s construct validity in this population. Total psychopathy and Self-Centered Impulsivity were positively associated with …

Pfas Levels In Hair: Comparing Us Populations To Global Trends, Ashef Ameer

Student Theses

Per- and polyfluoroalkyl substances (PFAS) are synthetic chemicals that raise significant toxicological concerns due to their environmental persistence and potential health hazards. This research examines the presence and concentration of selected PFAS compounds in human hair samples from volunteers in New York, comparing these results with global trends found in peer-reviewed research.

Investigation Into The Microbiome Of Blow Fly Eggs Using Microseqtm Id, Samantha S. Davis, Drusilla Sheridan, Jennifer Rosati

Undergraduate Research

There is little published research characterizing the microbiome associated with blow fly eggs and how they may affect the colonization behaviors of certain blow fly species. Once deposited, blow fly eggs are rapidly introduced to a diverse range of microorganisms, which can vary depending on the species of blow fly, the environment, and the decomposition stage of the substrate (Junqueira et al., 2017). Since blow flies are among the first insects to colonize decomposing remains, the microbial communities present on their eggs could serve as key indicators of the decomposition stage at the time of egg-laying, thus providing a potential …

Examining The Impact Of Expert Testimony And/Or Mindfulness Training On Jurors’ Appraisals Of False Confessions, Izabela Rzaca

Student Theses

False confessions continue to be the leading cause of wrongful convictions in the United States, often because of coercive interrogation tactics (Kassin, 2008; Leo & Ofshe, 1998). Jurors frequently view confession evidence as highly persuasive, even when situations suggest it may be false (Kassin & Sukel, 1997). A confession becomes important when there are no other forms of evidence against the defendant, especially in cases where police detectives are pressured to decipher the crime (Gross, 2004). Additionally, confessions have shown to override other types of evidence when jurors make their decisions (Leo et al., 2013). To address this issue, the …

A Qualitative Nmr And Histological Analysis Of Adipocere Formation In Different Aqueous Environments Using Sus Scrofa Models, Mia M. Sorrentino

Student Theses

Adipocere is a wax-like crust that has the potential to form over corpses in moist, humid, and anaerobic environments, preserving them in a process similar to that of mummification. The substance can be identified within 3-6 months postmortem and is characterized by the ratio of saturated fatty acids to unsaturated fatty acids. Palmitic acid and stearic acid are the most abundant in comparison to myristic and oleic acids. The goal of this study was to investigate factors affecting adipocere formation in different aqueous environments. Pork belly samples were submerged in water samples collected from different places around New York City …

Bullet Ricochet And Tunnelling Of Wood Substrates, Abdelrahman Khalifa

Student Theses

With the overall rise in shooting incidents throughout the country, most notably in urban areas, the capabilities and limitations of current forensic examinations of firearms-related incidents have become more apparent. An underappreciated aspect of shooting incidents is the phenomenon of bullet ricochet, which has led to ricochet-related injuries, with some cases proving fatal. Although there are processes and generally accepted standards for bullet trajectory analysis, ricochet analysis typically requires outside input from firearm examiners. Additionally, current research regarding ricochet on wood surfaces remains less thoroughly investigated than ricochet analysis on other yielding surfaces. The goal of this research was to …

Exploring The Biasing Effects Of Gender On Personality Disorder Diagnoses Formulated By Artificial Intelligence, Zoe Colclough

Student Theses

Gender bias is prevalent in personality disorder assessments, and while artificial intelligence has been posited as a solution to improve diagnostic objectivity and accuracy, the potential for such technologies to propagate human gender bias in mental health contexts remains underexplored. This study investigated the influences of gender bias on the diagnostic performance of ChatGPT-4o for personality disorders using three factorial research designs, which involved experimentally manipulating patient gender in a combined sample of 360 vignettes and case studies. Vignettes were synthesized through a novel artificial intelligence-assisted methodology established for this research, and case studies were identified from the literature. Significant …

Transfer Of Material Derived From Polymer-Jacketed Bullets During Cycling And Discharge, Ethan A. Frazer

Student Theses

The goal of this study was to determine alternative ways to connect a polymer-coated bullet to the handgun from which it was fired. Polymer-coated bullets are lead projectiles encased in a synthetic coating, which may vary between brands and/or models, to reduce barrel friction and heavy metal exposure. Federal Syntech^® Total Synthetic Jacket (TSJ) ammunition presents unique challenges to firearms examiners as its synthetic coating may not retain the individualizing striations found in traditional unjacketed or metal-jacketed bullets.

In this study, 9mm TSJ ammunition was fired through multiple traditionally rifled aftermarket Glock barrels. Cloth targets were set up at …

Examining Portrayals Of Gender In The Design Of Ai Voice Assistants, Olivia Fratangelo

Student Theses

This capstone project provides a theoretical framework for shifting the ways in which we think about and discuss anthropomorphized features of technological products, focusing specifically on applying this framework to the gendered design of AI voice assistants. The goal in providing this framework is to prompt readers to consider how we can think more critically about technology beyond our “preferences” and biases. Our roles as consumers of technology do not have to be passive ones. In fact, the dialectical relationship between humanity and technology makes everyone who contributes to society not just a consumer, but a developer of technology in …

Punishing Pregnancy Loss: Miscarriage Criminalization As An Embodied Carceral Practice, Robin O'Hanlon

Publications and Research

The persecution of Brittany Watts, a 34-year-old Black Ohio woman arrested in September 2023 after experiencing a miscarriage, is emblematic of pregnancy loss criminalization as an embodied carceral practice. In the United States, the expansion of “fetal personhood” laws, coupled with a desire to punish imperfect pregnancies, have coalesced to produce policies and practices which actively police and criminalize pregnancy loss. The carceral regime of fetal personhood is further reinforced by medical paternalism and surveillance. I argue that the policies and practices which police pregnancy loss are rooted in a series of carceral logics, which are in turn reinforced by …

Twelve volunteers were asked to place one fidget blaster each in the glove box and underneath the driver’s seat from behind. After the seven-day period, the volunteers returned the fidget blasters, donated a reference sample, and filled out a questionnaire. The grip, slide, and trigger were swabbed for DNA and extracted. The extracts were quantified to determine the concentration of human DNA, and if the samples met the PCR threshold to be genotyped. The …

Overlooking The Utility Of The Tattoo As An Investigatory Lead: An Exploratory Study Of Tattoo Documentation Quality Among Investigators And Medical Examiners, Deanna Corsetti

Student Theses

Tattoos have not only served as a subject of interest across cultures and disciplines for centuries, but also serve as a critical component of forensic investigations. Tattoos as traces–when properly identified and documented–serve as a valuable investigatory lead in cold, missing persons and unidentified remains cases. By examining the locations, dimensions, colors, and overall imagery of tattoos, investigators are able to use tattoos as a method of rapid, tentative identification of human remains (Miranda 2019). This study seeks to evaluate the quality and scope of tattoo documentation in cases classified as being unsolved. Specifically, tattoo data was collected from redacted …

Community-Level Analysis Of Anti-Asian Hate Crime, Jisoo Cho, Jinuk Jeong, Christopher Han-Fai Seto

Publications and Research

Motivated by the surge in anti-Asian hate crimes during the COVID-19 pandemic, this study examines the community characteristics associated with the likelihood of their occurrence from 2020 to 2023 through interracial conflict and social disorganization perspectives. Analyzing data from the New York City Police Department and the American Community Survey across 2,198 census tracts, we find that communities with higher levels of Asian population, racial heterogeneity, and residential instability have higher odds of experiencing anti-Asian hate crime. However, concentrated disadvantage and defended neighborhoods (White, Black, and Hispanic) are not significant across all estimated models. These findings have important implications for …

From Flames To Change: An Exploration Of Housing, Fire, And Inequity, Helen Underhill, Charles R. Jennings, Brian Meacham, Danielle Antonellis

Publications and Research

Housing and fire safety are deeply connected: inadequate and poorly maintained housing poses heightened fire risk for occupants. An individual or household’s housing situation (including limited or constrained choice) interacts with issues such as affordability, access, location, quality, safety, occupancy levels, tenure type, and resident or immigration status. These dynamics shape vulnerability, and inequity becomes most visible in the event of a fire. The extreme end of this spectrum includes the unhoused, who occupy structures entirely outside of regulatory systems with little or no fire protection.

A Meta-Analysis Of Intimate Partner Violence Treatment Programs: The Role Of Risk-Need-Responsivity In Treatment Effectiveness, Irina Fanarraga

Dissertations, Theses, and Capstone Projects

Nationally, it is estimated that over 17 million people experience victimization by an intimate partner every year. Additionally, individuals who perpetuate intimate partner violence (IPV) often have high rates of re-offending, potentially as high as 60%. IPV Treatment Programs (ITPs) are interventions designed to reduce recidivism among intimate partner violent individuals by changing their thinking and behaviors, ultimately leading to increased victim safety. Although there is significant evidence to suggest that correctional treatment programs can reduce re-offending, the literature on ITPs is less clear about their effectiveness in reducing recidivism among participants. Furthermore, while other correctional interventions have taken more …
