Disentangling The Effect Of Criminal Legal System Involvement On Mental Health In The United States, Pui Ying Chan

Dissertations and Theses

BACKGROUND: Interactions with the criminal legal system (CLS), such as through arrest or incarceration, are relatively common in the United States (US) and are increasingly recognized as social risk factors for poor mental health. Previous studies have reported a positive association between CLS involvement and poor mental health, with some theoretical frameworks, including the ecosocial theory and the stress process paradigm, supporting a plausible causal relationship. However, prior research has significant limitations in providing casual evidence given possible reverse causation in cross-sectional studies and insufficient consideration for the dynamics between CLS exposures, mental health status, and related confounders over time …

Implementation Of A Forensic Ancestry Inference Indel Panel, Jacqueline Molina

Student Theses

Ancestry-informative markers (AIMs) are genetic variants that exhibit significant frequency differences between populations, making them valuable tools for inferring biogeographical ancestry in forensic investigations. Insertion/deletion polymorphisms (INDELs) offer particular advantages for degraded forensic samples due to their short amplicon sizes and binary allelic nature. As forensic laboratories adopt newer instrumentation, validation of established assays becomes critical to ensure analytical continuity and reliability. This study evaluated the comparative performance of the SeqStudio™ Genetic Analyzer in detecting a 46 AIMs INDEL multiplex panel, previously established with the ABI 3130 Genetic Analyzer. Four commercial blood samples were analyzed using both platforms to assess …

Indirect Dna Transfer To Duct Tape Rolls Stored In Cars, Yuching Chung

Student Theses

This project investigated the accumulation of DNA on duct tape rolls stored in cars. Specifically, we analyzed samples recovered from three areas (the inside, outside, and flat sides) of unused duct tape stored under the driver's seat and trunk of cars for seven days. Twelve volunteers were recruited, resulting in 64 DNA samples from 12 cars. We evaluated DNA quantities and STR genotyping outcomes after amplification with the GlobalFiler™ kit. On average, the DNA yields from under the driver's seat were higher than from the trunk, but the difference was not significant. The inside of the tape roll yielded significantly …

Exploring Variability Of The Cg18562578 Methylquant Assay For The Forensic Discrimination Of Monozygotic Twins, Sydney E. Arnold

Student Theses

Monozygotic (MZ) twins possess identical DNA sequences, posing a problem for forensic scientists, as they are incapable of distinguishing MZ twins from each other using traditional DNA identification methods. However, the epigenomes of MZ twins will differ and might be used for their forensic discrimination. Here, we explored the variability of an assay previously developed by our laboratory that showed high discrimination potential for MZ twins using buccal swab DNA, cg18562578 MethylQuant. We measured precision at each step: bisulfite conversion, nested PCR, and qPCR, reproducibility, and repeatability. DNA methylation ratios were compared between two analysts carrying each step using the …

Internet Of Things And Modern Digital Evidence Collection, Muhammad T. Haider

Student Theses

The ever-evolving landscape of technology and its innovations are populating our houses, streets and all kinds of industries. The use of smart devices is booming from most developed nations to underdeveloped countries. The complications which come with the use of the Internet of Things has been an active discussion for the past many years. If we look around in a room of 30 people, we will most likely find double the amount of IoT devices than the people in that room. All of those devices are connected to the Internet, and are communicating with data servers across the world. The …

Cg18562578 Methylquant Assay For The Discrimination Of Monozygotic Twins, Amber P. Chauca

Student Theses

Monozygotic (MZ) twins have identical DNA, making traditional profiling methods insufficient in their discrimination. However, MZ twins can be differentiated by their levels of DNA methylation. Our research group previously developed a methodology to detect cg18562578 DNA methylation levels in MZ twins based on a two- step PCR approach and a cg18562578 MethylQuant Assay. That study generated data for only 64% of the samples it investigated, and showed a discrimination power of 77% to discriminate between MZ twins. Here, we used the same methodology but a different approach to determine DNA methylation in 73 previously unsuccessful twin pairs. We diluted …

Further Investigation Of Environmental Factors On Rapid Shear In Fibers Of A Polyester-Cotton Blend, Daniel K. Oh

Student Theses

Rapid shear is a process that occurs in thermoplastic materials when they interact with a high-velocity impact. In forensics, these interactions would typically be from a bullet interacting with clothing that consisted of synthetic fibers. When the interaction occurs, bulb-like shapes appear on damaged fiber ends, distinguishing them from other kinds of damage. The reason why these shapes occur is varied, but one prevailing factor seems to be the heat generated by the impact.

In prior experiments, the factor of temperature being important to the formation of the phenomenon, different environmental simulations that affected the sample’s temperature were done on …

Bystanders Intervening During Acts Of Cyberbullying: Examining The Moderating Influence Of “Likes” And Pleas For Help, Joseph Kallman

Student Theses

Abstract

Cyberbullying research has only recently begun exploring “cyberstanders,” also known as bystanders, and their role in cyberbullying, as well as testing the bystander effect (Barlinska et al., 2013; Machackova et al., 2013; Obermaier et al., 2016; Shultz et al., 2014). In the current study, we aim to deepen our understanding of the bystander effect by manipulating the number of likes, which will indicate the number of bystanders present and the plea for help on social media via Twitter among college students, by examining how participants respond to fictitious cyberbullying incidents. The results of this study did not support our …

Exploring Adversarial Threats To Neuralhash: A Perceptual Hashing Algorithm, Gurleen Kaur

Student Theses

Perceptual hashing algorithms are algorithms that generate content-based image hashes by extracting perceptual features from the images. Unlike cryptographic hashes, which exhibit significant changes with even slight input alterations, perceptual hashes do not change when modifications like compression, color correction and brightness are applied to the images. These hashes are designed to remain similar for inputs that are visually or perceptually alike, which has led to their widespread application in detecting duplicate images, finding similar images for reverse image search and to detecting inappropriate content of Child sexual abuse (CSAM) images by comparing image hashes with dataset of known perceptual …

Characterization Of Dna Background On Duct Tape Stored In Domestic Environments, Elaan A. Lukasiewicz

Student Theses

With lower detection limits for forensic DNA analysis, it is important to have a better understanding of background DNA levels unrelated to the crime to facilitate accurate data interpretation. Duct tape is used in crimes, e.g. to bind victims and seal drug packaging, and may be tested for DNA. To determine DNA background levels, twelve volunteers were recruited to donate a used roll of duct tape from their home. The duct tape was divided into three areas: inside, outside, and sides of the roll, and swabbed for DNA. The average concentration of DNA was determined for the inside (0.0723 ng/µL …

Str Analysis Performance Comparison For Two Capillary Electrophoresis Instruments: The Seqstudio And The 3500 Genetic Analyzers, Yana Leichyk

Student Theses

This study compares the performance of two capillary electrophoresis instruments—the SeqStudio™ Genetic Analyzer and the 3500™ Genetic Analyzer—for forensic short tandem repeat (STR) analysis. Using the GlobalFiler STR kit and certified reference material (SRM 2391d), five key performance metrics were evaluated: sizing precision, signal reproducibility, detection sensitivity, mixture resolution, and overload tolerance. STR profiles were generated from single-source and mixture samples with DNA inputs ranging from 500 pg to 15.6 pg. Both instruments met the < 0.15 bp sizing precision requirement for forensic casework. Signal reproducibility tests showed that the SeqStudio often produced higher average RFU values, but with greater variability, while the 3500 demonstrated more stable signal performance across days and samples. Mixture detection was effective on both platforms up to 1:10 ratios. Dropout of minor alleles began to appear at 1:20 ratios, especially in green and yellow dye channels, on both instruments. Sensitivity studies confirmed full profile recovery down to 62.5 pg, with increasing allelic and locus dropout at lower inputs. Enhanced injection voltage (1.5 kV) did not improve low-template performance. In overload testing (1–5 ng input), the 3500 maintained a consistent signal output, while the SeqStudio exhibited signal suppression at 5 ng, likely due to internal normalization. The SeqStudio exhibited better spectral overlap compensation, with fewer occurrences of spectral bleed-through artifacts. These findings support the use of both platforms in forensic casework, while emphasizing the importance of platform-specific calibration and analytical threshold settings for optimal performance.

Introduction To Sociology: Deviance And Crime, Dr. Marcia Morrison Ph.D.

Open Educational Resources

Abstract

This paper explores the multifaceted concepts of deviance and crime by synthesizing major theoretical perspectives and contemporary research findings. Beginning with the fluid and culturally contingent nature of deviance, the discussion highlights how social norms, historical context, and power structures define what is considered deviant behavior. It examines the influence of economic elites on moral and legal standards, drawing on Marxist analyses, and considers the impact of societal labeling on personal identity through Lemert’s labeling theory.

The paper then delves into biological foundations of criminality, reviewing Lombroso’s atavism theory and modern research on genetic predispositions, including twin, adoption, and …

Environmental Enrichment Reduces Cue-Induced Reinstatement Of Heroin-Seeking Following Prolonged Use And Reverses Region-Specific Heroin-Induced Neuroadaptations, Apoorva Vashisht

Dissertations, Theses, and Capstone Projects

Background: Relapse remains the greatest barrier to long-term recovery and the consequential rising overdose-related mortality in heroin use disorder (HUD). Currently available behavioral and pharmacological interventions fail to extend their benefits beyond the duration of the treatment. Additionally, opioid agonist-based medications accompany harmful neurobiological risks and propensity to promote further drug-seeking post-treatment. We have shown that environmental enrichment (EE), as a therapeutic strategy applied after drug intravenous-self administration (IVSA), can effectively facilitate abstinence and reduce reinstatement of drug-seeking in animal models of drug abuse. Moreover, dopamine receptors like D1 and D3, and mu-opioid (MO) receptors are well known for their …

The Long Arm Of The Law: The Far-Reaching Effects Of The Carceral State On Families, Madison Squiers

Dissertations, Theses, and Capstone Projects

This thesis investigates the extended consequences of mass incarceration in the United States, focusing on the social, economic, and psychological impacts on the nuclear families of incarcerated individuals. Through a comprehensive literature review of peer-reviewed studies published between 2000 and 2024, this study highlights how female partners and children of imprisoned men face significant hardships, including emotional trauma, financial instability, and social stigma. These burdens are most acutely experienced by low-income families and communities of color, reflecting broader patterns of structural inequality. The findings underscore how punitive criminal justice policies—especially mandatory minimum sentencing and the War on Drugs—have created ripple …

The Invisible Hand Of Networked Repression, Thuy Anh Tran

Dissertations, Theses, and Capstone Projects

U.S. history is awash with contentious episodes involving a legion of governmental and non-governmental actors operating through an array of means and arenas to destroy the political opposition. Yet, there has been little systematic examination in the repression literature of how and why repressive efforts proliferate so far beyond the police, military, and intelligence agencies tasked and equipped to preserve the existing order. This dissertation presents a novel framework for studying the relational basis of repression—particularly as it is organized, mobilized, and extended through a networked social structure. Social network analysis and interpretive case studies are conducted on two historical …

Stereotype Engineering, Ian Olasov

Dissertations, Theses, and Capstone Projects

I offer an account of a novel variety of conceptual engineering, which I call stereotype engineering. Someone engineers a stereotype when they work to change the typicality effects associated with a category or expression (performance on goodness-of-example tasks, feature listing tasks, and accuracy rates and response times in recognition and retrieval tasks), without necessarily changing the concept of that category or the semantic value of the expression. I offer a number of examples of stereotype engineering in popular discourse – from rape activism to expansive uses of “white supremacy” and “ethnic cleansing,” to the hashtags #BlackGirlMagic and #MyNYPD, to advocacy …

Counter-Hegemony In The Captive State: Recasting Katrina’S Carceral Legacy Through Conjuncture, Joseph S. Muratore

Dissertations, Theses, and Capstone Projects

This thesis traces the historical development and contemporary manifestations of carceral power in Louisiana, arguing that racialized systems of control—from slavery and convict leasing to mass incarceration—have been sustained through shifting alliances of political and economic elites. Using The Historic New Orleans Collection (HNOC) and its exhibit Captive State: Louisiana and the Making of Mass Incarceration as a foundational timeline, this study demonstrates how Bourbonism forged a regional bloc that institutionalized racial domination through incarceration and labor exploitation, later reconstituted through neoliberal policies of abandonment, privatization, and militarization. I chose to focus on Hurricane Katrina because its aftermath reflects many …

Moving The Needle: The Policy Of Change On Syringe Access, New York City And State, 1988–2023, Joyce Rivera

Dissertations, Theses, and Capstone Projects

By the mid-1980s, the HIV/AIDS epidemic breached a longstanding consensus between the political class and its bureaucratic alliances that had relied for decades on attitudes and orientations that championed punitive prohibition toward drugs as a bedrock principle of policy making. This ‘focusing event’ created an opening for HIV/AIDS activists to build a movement that offered an alternative, a more effective and just approach to how government policies and practices can manage illegal drugs and the persons who use drugs.

The dissertation uses several theoretical and methodological tools to address the central research objective that highlights the critical role played by …

Drawing from critical race theory and the minority stress model, the study explores how race, discharge status, military experiences, and mental health conditions intersect to affect potential eligibility for and receipt of VA healthcare and benefits. Utilizing a secondary analysis of data from the Survey of Prison Inmates (SPI), the research employs quantitative methods to examine whether disparities exist in discharge characterizations, potential eligibility for VA care, and service utilization by race. Findings highlight …

Menstrual Math: The Price Of Bleeding, Gabrielle Langston

Dissertations, Theses, and Capstone Projects

This project examines the landscape of menstrual equity in the United States through a data storytelling lens, focusing on state-level policies regarding taxation and access to menstrual products. The analysis explores which states impose sales tax on menstrual products, if state schools provide free menstrual products, and which states ensure access for incarcerated individuals using publicly available datasets from advocacy groups. Additionally, there is an investigation into potential correlations between the gender wage gap and states that tax menstrual products, shedding light on economic and policy disparities.

Through its data visualizations, this project aims to provide a clear, although not …

Punitive Desire, Belief In Redeemability, And Support For Rehabilitation: A Comparison Of Victimized And Non-Victimized Individuals' Attitudes Toward Criminal Offenders, Caleb Linder

Student Theses

This study examined the attitudes of victimized and non-victimized individuals toward criminal offenders, investigating whether the supportive attitudes observed in Spoo et al. (2018) extend beyond sexual offenses to other types of crime. The study also explored how the perpetrator’s relationship to the victim (family member vs. stranger) and participants’ previous exposure to the justice system influenced their perceptions of offenders. Contrary to our hypothesis, punitive attitudes did not differ between participants with a history of victimization and those without. Additionally, there was no significant difference in punitive attitudes toward stranger offenders compared to offenders known to the victim. Furthermore, …

Belonging Against The Odds: Exploring Restorative Justice Practices As Pathways To Foster Belonging In New York City Transfer Schools, Miguel Rodriguez

Dissertations, Theses, and Capstone Projects

The U.S. education system perpetuates structural inequities that disproportionately affect Black students with the School-to-Prison Pipeline (STPPL) criminalizing them through Zero-Tolerance policies. Transfer schools are often a last resort for students pushed out of traditional schools provide a lens to examine the impact of Restorative Justice Practices (RJP) and Black student representation on belonging. This quantitative dissertation study analyzes secondary data from the NYC Department of Education using multivariate models to explore the relationship between RJPs and sense of belonging (SOB). Model 1 found that discussing feelings and emotions at school (Tier 1 RJP) had the strongest association with SOB …

Non-Destructive Dry Vacuum Recovery Of Dna From Fabric, Emily Sam-Zee-Moi

Student Theses

Trace DNA has proved to be a reliable forensic tool when investigating crimes. Current methods of trace DNA recovery from fabric include cutting, swabbing, scraping, and tape lifting. A dry vacuum collection method originally developed for paper evidence is an alternative nondestructive option for DNA collection from fabric. This research evaluated the success of the dry vacuum technique on pieces of cotton fabric that had been briefly touched as well as the effectiveness of different moistening agents and filters. The samples were designed to simulate an assault with the suspect grabbing the clothing of their victim. Volunteers created samples by …

The Effect Of Bullet Morphology And Intermediate Targets On Bullet Path, Natalia Aguilar

Student Theses

A key feature of shooting reconstruction is trajectory analysis. There are several different methods of assessing this from the bullet impact mark including: best-fit ellipse, lead-in, trajectory rod, 3D laser scanning, and machine learning. While these function in differently, many share a common fault. Few trajectory analysis techniques evaluate the difference in bullet path for bullet morphology. This raises the question: does the morphology of a bullet influence its degree of deviation when interacting with a target material? This study investigates the difference in bullet trajectories through drywall for 9mm full metal jacket (FMJ) and jacketed hollow point (JHP) ammunition …

A Seat At The Schoolhouse Table: Reimagining Education Through Afrofuturist And Womanist Theory, Natasha M. Capers

Student Theses

“A Seat at the Schoolhouse Table: Reimagining Education Through Afrofuturist and Womanist Theory” critically examines how curriculum, even when well-intentioned, can perpetuate harm by excluding the lived experiences of marginalized communities—especially Black, Indigenous, and LGBTQIA+ students. Using a real middle school immigration assignment given to the author's son as a case study, this capstone deconstructs the structural biases embedded in curriculum design and proposes a radical reimagining through the liberatory lenses of Afrofuturism and Womanism. Blending scholarly inquiry, personal narrative, and community-based interviews, this project offers a restructured assignment that centers joy, identity, and speculative storytelling as tools for educational …

Dna Extraction And Species Determination Of Historic Museum Pelt Samples, Selin Ates

Student Theses

The identity of the fur covering the sculpture named Object in the Museum of Modern Art has remained a mystery since its creation in 1936 by Meret Oppenheim. DNA testing can possibly provide an answer, but to preserve the integrity of the sculpture, only a very small piece of the fur can be sampled. Prior to testing Object, testing using museum samples was performed to determine whether DNA of a sufficient quantity and quality can be extracted and sequenced. Several DNA extraction and sample washing methods were tested to examine the effects on the DNA of museum pelts aged …

Quick And Easy Method For The Determination Of Cocaine And Six Metabolites In Postmortem Hair, Samantha C. Mulkeen

Student Theses

Hair testing is increasing in popularity in toxicology because of its long window of detection and ease of collection and sample storage. However, it has its limitations largely due to external contamination of drugs. In particular, cocaine (COC) is a common offender of this as it has several routes of consumption. Analyzing metabolites of COC may be the key to distinguishing between consumption and external contamination. The aim of the present study was to develop a quick, easy, and sensitive method for the detection and quantification of COC, benzoylecgonine (BE), norcocaine (NCOC), cocaethylene (CE), anhydroecgonine methyl ester (AEME), meta-hydroxy-cocaine (m-OH-COC), …
