The Role Of Temperament In Criminal Trajectories: Development, Stability, And Predictive Power Across The Life Course, Joshua A. Lang

Dissertations, Theses, and Capstone Projects

Temperament, an individual's largely innate tendency to experience and regulate responses to their environment, has long been studied but was only recently introduced as a primary predictor of criminal behavior (DeLisi & Vaughn, 2014). While prior criminological theories have incorporated temperament-related constructs, such as negative affect (Agnew, 1992; Moffitt, 1993) and self-control (Gottfredson & Hirschi, 1990), no other theory has explicitly positioned temperament as the central factor in offending. DeLisi and Vaughn’s temperament-based theory of antisocial behavior posits that individuals with low effortful control and high negative emotionality—features of a difficult temperament—are more likely to engage in criminal behavior. Despite …

Viability Of Manually Passing Projectiles Through The Barrel Of A Firearm In Lieu Of Test Firing, Mara V. Mineo

Student Theses

Forensic examinations of discharged projectiles are made possible by the toolmarks and striations made by the barrel the projectiles pass through. Suspect barrels are attached to firearms and test fired to compare these toolmarks and striations with found evidence. However, physically damaged barrels could potentially be unable to produce exemplars. This study tests the viability of manually passing projectiles through stationary barrels as a meaningful and accurate means to produce acceptable exemplars that are able to be compared against recovered evidence. A total of 18 projectiles were manually passed between two distinct Glock handgun barrels and viewed under a comparison …

Effect Of Food Resource, Preservation Method, And Preservation Duration On Larval Size Of Forensically Important Fly Species (Order: Diptera), John Zukowski

Student Theses

Forensic entomology is a vital discipline that can aid in the proceedings of criminal cases. Larval age and development are important aspects to consider when utilizing blow flies (Family: Calliphoridae) for estimates pertaining to the initial time of colonization (TOC), which contributes to postmortem interval (PMI) estimations. Thus, it is important to understand the factors that influence larval size and development, since larval size is commonly used as a proxy for age. Larvae of three species of flies, Lucilia sericata (Meigen), Calliphora vicina (Robineau-Desvoidy), and Phormia regina (Meigen), were reared on five different food resources. Specimens of L. sericata and …

Breaking Point: Exploring Side Bets, Support, And Pension Investment As Predictors Of Turnover Intention In Urban Policing, Kenneth M. Quick, Kevin T. Wolff

Publications and Research

Guided by Becker’s side-bet theory, this study examines turnover intentions among officers in the New York City Police Department by assessing pension investment and affective commitment as accumulated organizational “side bets,” alongside job satisfaction, perceived organizational support, and workplace conditions. Data was drawn from an online survey of 1,454 officers. Population weights based on gender, race/ethnicity, and rank were applied to improve representativeness. Weighted multinomial logistic regression models examined predictors of turnover intention, while second-difference tests of average marginal effects (AMEs) assessed whether workplace factors operated differently across tenure groups. Results indicate that perceived organizational attitudes and workplace conditions significantly …

Investigating Potential Bias In Public Acceptance Of Restorative Justice: The Influence Of Situational And Offender Characteristics, Kiara Haynes

Student Theses

Restorative Justice has been an emerging justice mechanism in the U.S. since the 1970s that advocates are working to expand more widely throughout the justice system. Due to victims and the broader community of the offender being an integral part of the Restorative Justice process, it is critical to consider the general public's support of this novel justice mechanism, as well as the influence that social biases among the public may have on the experience of defendants going through the system. The study conducted examined the effect that social biases toward an offender's personal characteristics have on attitudes and opinions …

Adversarial Robustness Of Perceptual Hashing Systems: A Unified Security Evaluation Framework, Avijit Roy

Student Theses

Social network platforms, child safety organizations, and image provenance systems use perceptual hashing to identify known child sexual abuse material (CSAM), support content moderation and reverse image search, and verify image integrity. Perceptual hashing works by producing similar fingerprints for visually similar images, even after common transformations such as compression, resizing, or minor brightness changes. This useful similarity-preserving property also creates an adversarial attack surface, as attackers can use AI-assisted or conventional image manipulation techniques to move a hash across a matching threshold while maintaining visual similarity, often without access to specialized hardware.

The security failures produced by adversarial attacks …

A Qualitative And Quantitative Comparative Analysis Of Ballistic Bone Trauma From Frangible And Full Metal Jacket Projectiles, Hajar S. Hassan

Student Theses

Ballistic bone research is essential as 90% of homicides with the use of a firearm include injuries to bone. Forensic anthropologists use ballistic bone trauma to gather details and reconstruct an event, but ballistic bone trauma depends on many intrinsic and extrinsic factors. These factors include the type of bone, the type of firearm, and the type of ammunition. As new ammunition and firearms emerge, the literature on ballistic bone trauma remains limited. This novel study compares the bone trauma from the most common projectile, the full metal jacket, to a frangible projectile which is made to break upon impact. …

Publications and Research

The current study examines the relationships between specific psychiatric diagnoses and both adolescent suicide and reoffending, the implications of adverse childhood experiences on these outcomes, and assesses whether these relationships are moderated by sex. Using a multilayer multiyear statewide sample of 6,515 adolescents who completed juvenile justice residential placements, logistic regression and moderation models were used to examine these relationships. Findings demonstrate that the rate of suicidal ideation was 2.5 times higher for female youth, while the recidivism rate was 1.7 times higher for males. Psychiatric diagnoses prevalence ranged from 65.9% for conduct disorder to less than 1% for personality …

A Meta-Analysis On Joinder Effects: Do They All Have The Same Magnitude?, Amelia M. Tisk

Student Theses

The present meta-analysis examined whether different forms of joinder and procedural consolidation produce varying levels of prejudice in adjudicative decision-making. Although joinder procedures improve judicial efficiency, psychological research has suggested that combining charges, defendants, or plaintiffs within a single proceeding may increase conviction likelihood, liability judgments, and broader perceptions of wrongdoing. A random-effects meta-analysis was conducted across 22 independent study effects examining charge joinder, defendant consolidation, plaintiff consolidation, multiple-complainant procedures, and related aggregation paradigms. Effect sizes were converted to Pearson’s r whenever possible. Overall, procedural aggregation produced a moderate effect on adjudicative outcomes, r = .27, 95% CI [.22, .32]. …

When Disaster Strikes Y’All Street: A Study On Cross-Sector Collaboration In Protecting U.S. Financial Critical Infrastructure, Rachael A. Zerr, John Friedlander

Publications and Research

This exploratory research examines public-private collaboration between corporate security leaders and local emergency responders in the North Texas financial corridor known as “Y’all Street.” Using perception-based survey data from senior representatives in the private and public sectors, the paper evaluates partnership strength, preparedness activities, information sharing, and operational coordination. Findings indicate that collaborative practices such as facility tours, joint exercises, and emergency planning are present, but that partnership maturity remains uneven and is not yet fully standardized across the corridor. The research concludes that more formalized and institutionalized coordination will be necessary to strengthen resilience as the region’s financial significance …

Method Development And Optimization For The Detection Of Synthetic Cannabinoids In Hair Using Lc-Msms, Linda K. Obeng

Student Theses

Synthetic cannabinoids represent one of the most prevalent and high-risk classes of New Psychoactive Substances (NPS), continuously evolving in structure and potency. Their widespread presence in seized materials and toxicology casework underscores the growing need for reliable analytical methods capable of detecting these compounds in biological matrices. Hair offers several advantages for drug testing, including a long detection window, minimal invasiveness, and resistance to adulteration; however, detecting synthetic cannabinoids in hair remains challenging due to their low incorporation levels and structural diversity. This study focuses on the method development and optimization of an LC-MS/MS technique for the detection of selected …

Fast & Forensic: Rapid Detection & Quantitation Of 30 + Emerging Novel Psychoactive Substances In Hair Using Lc-Ms/Ms, Seokjin Hwang

Student Theses

The continuous emergence of novel psychoactive substances (NPS) poses a significant challenge for forensic and clinical toxicologists, due to their structural diversity, rapid turnover on the illicit drug market, and limited toxicological information. Hair is a powerful matrix for retrospective drug exposure assessment and monitoring NPS worldwide. Not only does it provide a broad window of detection but also a simple sample exchange amongst laboratories. However, the extraction of multi-class NPS in a single method remains an analytical challenge. Therefore, there is an urgent need for extraction techniques and analytical methods that are both rapid and capable of multi-class quantitation …

Eyewitness Consent To Be Video Recorded: Implications For Identification Accuracy And Confidence, Sarah Argüelles

Student Theses

Recently, a recommendation has emerged for law enforcement to record the full eyewitness identification procedure, recognizing the critical role eyewitness testimony plays in the justice system (Wells et al., 2020). However, in some states, such as New York, law enforcement is required to seek consent from witnesses before recording (Municipal Police Training Council & Division of Criminal Justice Services, 2017). Since this practice is relatively new, there has been limited research on how obtaining consent may affect eyewitness accuracy. It was hypothesized that obtaining consent to video record could be linked to a witness’s confidence in their identification, with higher …

Rape Myth Acceptance, Pretrial Publicity, And Decision-Making: An Examination Of Perceptions Of Victim Credibility And Perpetrator Guilt In A Real-World Sexual Assault Case, Lindsey Strouse

Student Theses

This study explores how the media narratives and political perspective of pretrial publicity (PTP) can influence jurors’ perceptions in sexual assault cases, raising significant concerns about justice in courtrooms. Specifically, it examines whether media framing of a real-life sexual assault case — through varying media narratives, with media that either challenges or endorses rape myths, and media source (liberal vs. conservative) — affects mock jurors’ rape myth acceptance (RMA), views of victim credibility, and judgements of perpetrator guilt. Participants first completed a RMA scale, then read mock news articles varying in media narrative and political affiliations (media source), followed by …

Scripted For Surveillance: Parole Revocation Hearings And The Performance Of Procedure In New York, Kelsey G. Greeff

Dissertations, Theses, and Capstone Projects

This thesis examines parole revocation hearings in New York as complex performances that extend carceral control beyond prison walls. Drawing on a composite vignette from the Bronx parole court, it analyzes the interplay between procedural reform, constitutional due process, and neoliberal governance. Using a dramaturgical framework informed by Michel Foucault’s discourse analysis and Judith Butler’s theory of performativity, the study identifies four interrelated processes: the judge as director, who orchestrates hearings according to institutional priorities; normalization, where repetition embeds structural inequality as routine; type-marking, the classification of parolees into predefined roles through accumulated records and cues; and the extension of …

Effects Of Rapid Shearing Depending On Environmental Factors: Acrylic, Modacrylic, And Polypropylene Fibers, Charles K. Jin

Student Theses

Textiles can often be found damaged in forensic casework, and analysis of these defects can yield valuable information. Different methods of fiber fracture leave behind varying alterations in structure on individual fiber ends, leading to their possible identification and connection to a case. Interactions between high-speed impacts and synthetic fabrics composed of thermoplastic fibers are classified as rapid shear or high-speed tensile breaks. In these situations, unique fiber end characteristics can form due to excessive heat generation that is unable to dissipate quickly enough to prevent fiber end morphology from changing.

This study aimed to explore how different external conditions …

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 …

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 …

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 …

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 …

Fugitive Colors, Natalie Rose Eddings

Theses and Dissertations

My objects are meditations on intertwining themes of labor, rest, and interiority and their shadow sides—power, subjugation and the gaze. I couple materials that have millenia-long histories such as metals, glass, paper and clay with found objects and plat materials to illustrate narratives and exhume memories. Drawn from nature and technologies of land, plant stewardship and the domestic realm, I imagine my sculptures as life supporting vessels or magical enclosures.

Through sculpture, photography and printmaking, I build structures that are space of quiet to be filled with thought, healing and development. Like incubators and seed pods, my work is protective …

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 …

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 …

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 …
