Analysis Of Polymer-Coated Bullets Using Spectroscopic Methods, Liana R. Albano

Student Theses

Polymer-coated bullets have gained popularity because they can reduce the user’s exposure to heavy metals in the ammunition. The synthetic jacket, which surrounds the lead core, is advantageous because it prevents metal-on-metal contact between the bullet and the bore. A challenge for firearms identification is that polymer-coated bullets do not retain unique markings that can be used to identify the gun, the way standard metal-coated bullets do. However, metal-coated bullets will result in a similar challenge if the bullet is too deformed once it is recovered. Another issue is that the composition of the polymer coating was never disclosed by …

Extraction Of Challenging Forensic Samples Using The Microgem Dna Extraction Kit, Falyn R. Vega

Student Theses

In forensic science, DNA extraction can be a tedious and resource-intensive process. Extraction with Proteinase K is an industry standard but has its drawbacks, such as requiring multiple ionic detergents and washing steps. MicroGEM has developed a new enzyme called forensicGEM that is temperature-dependent and compatible with mesophilic enzymes, offering complete DNA extraction in about 20 minutes in a single tube, limiting contamination, loss of sample, and working time. ForensicGEM can extract DNA from highly degraded samples, potentially leading to more complete STR profiles. Highly degraded tissue and bone samples were collected and extracted with the forensicGEM …

Comparison Of Hydrolysis Efficiency And Performance Of Four Recombinant Β- Glucuronidase Enzymes For The Detection Of Opioids In Urine Samples By Lc-Ms/Ms, Christina Fernandez

Student Theses

The United States has been experiencing a nationwide public health crisis since introducing prescription opioids in the 1990s. A central problem with opioids is their highly addictive nature causing a dose-dependent respiratory depression leading to overdoses and deaths. Drug overdose deaths have risen in the past two decades, with opioids being the dominant driver of this epidemic. Given the circumstances, accurate and efficient confirmatory analysis of opioids in urine is essential to monitoring patients’ compliance and preventing drug diversion in clinical and forensic settings. The development of recombinant β-glucuronidases allows for the hydrolysis of glucuronidated opioids using a shorter incubation …

Detection Of Delta-9-Tetrahydrocannabinol And Cannabidiol In Utero Exposure By Umbilical Cord Analysis, Emily Pagano

Student Theses

With the rising consumption of cannabis and cannabinoid-containing products among different demographics, including pregnant women, it is increasingly necessary to develop analytical tools to be able to determine prenatal cannabis exposure. The aim of this study was to develop and validate a sensitive and specific method, using umbilical cord, to determine in utero exposure to delta-9-tetrahydrocannabinol (THC) and cannabidiol (CBD). After homogenization and hydrolysis, samples were extracted using liquid-liquid extraction and analyzed by liquid chromatography-tandem mass spectrometry (LC-MSMS). MS analysis was performed in electrospray ionization negative mode and two multiple reaction monitoring (MRM) transitions were monitored per analyte. The linearity …

Identification Of Different Hair Dyes In Dyed Hair Using Attenuated Total Reflectance (Atr Ft-Ir), Surface Enhancing Raman Spectroscopy (Sers) Techniques, Nicholas Lovera

Student Theses

This investigation compares the ability of Attenuated Total Reflection Fourier Transfer Infrared Spectroscopy (ATR FT-IR) and Surface Enhance Raman Spectroscopy (SERS) to identify and differentiate different hair dye brands on dyed hair samples. Hair is a common type of trace evidence found at crime scenes and can provide numerous information through forensic hair analysis. Cosmetic hair treatment such as dying the hair different colors has grown and became popular, thus it can be a very common type of trace evidence. This study can provide a forensic scientist an additional method for analyzing dyed hair samples. The goal was to compare …

Impact Of Blood Preservatives And Anticoagulants On Cannabinoid Quantitative Analysis, Bridget O'Leary

Student Theses

The expanded use of recreational and medicinal cannabis products, as well as the appearance of new cannabinoid derivatives, increases the importance of implementing pre-analytical (sample collection) protocols and the development of recommendations for cannabinoid testing in biological samples. The accurate quantification of cannabinoids in biological samples is critical for providing a correct result interpretation, especially if specific thresholds have been legally set, as in drugs and driving cases in certain states. Previous studies have mainly focused on the impact of time and temperature on the stability of delta-9-tetrahydrocannabinol (delta-9-THC) and metabolites in blood samples; however, the influence of the type …

An Offer You Cannot Refuse: Understanding The Elusive Construct Of "Voluntary" Plea Decisions, Melanie B. Fessinger

Dissertations, Theses, and Capstone Projects

Defendants often plead guilty in exchange for reduced punishments. Some argue that these reduced punishments are necessary for the functioning of the criminal justice system, whereas others argue that they are inherently coercive because they place a burden on the exercise of constitutional rights. This potential coercion is of concern because the constitution requires valid guilty pleas to be made by defendants voluntarily. However, “voluntary” is an elusive construct of which courts, scholars, and laypeople have differing definitions. Although limited research has focused specifically on perceptions of voluntary pleas, decades of research have shown that individuals generally perceive decisions more …

The Relationship Between Sexting Behaviors And Image-Based Sexual Abuse (Ibsa): Does Sexting Predict Ibsa?, Seunghye Yang

Student Theses

With development of technology, Image-Based Sexual Abuse (IBSA), a new type of sexual abuse, has emerged. It is defined as nonconsensually creating nude or sexual images of others; nonconsensually distributing nude or sexual images of others; and threatening to distribute nude or sexual images of others (Henry & Flynn, 2019; Powell et al., 2019). As this is a relatively new phenomenon, risk factors for IBSA are not yet well understood. It has been suggested that sexting may be a risk factor for IBSA as the two behaviors share some common characteristics. For example, both sexting and IBSA involve sending or …

Open Fire: The Expansion Of 9mm Hollow Point Bullets In Relation To Tissue Thickness, Abigail Wilson

Student Theses

Bullets can be broadly differentiated into jacketed and unjacketed groups. Jacketed ammunition can be further broken down based on the bullet’s design, one of which is hollow points. This research examines a representative brand of jacketed hollow point bullets used in a common caliber cartridge, the 9mm Luger. A jacketed hollow point bullet is designed to expand when it encounters a viscous medium such as tissue. This experiment simulated tissue using ballistic gelatin and simulated skin using a chamois overlay. As a positive and negative control, a series of bullets were fired into a full-size block of gelatin to achieve …

The Punitive Laboratory Of Neoliberalism: A Cross-National Examination, Beth A. Fera

Dissertations, Theses, and Capstone Projects

A large body of research has been produced to explain global punitive trends in recent decades. Neoliberalism, an economic philosophy expressed by market deregulation, privatization, and the retrenchment of social supports, has been offered as an explanation for increases in cross-national punitiveness. According to neoliberal penality theory, neoliberalism has shifted principles guiding punishment practices and the treatment of offenders, which has resulted in harsher national responses to crime. However, many tenets of this theory have not yet been tested empirically. Drawing heavily on propositions from neoliberal penality, group-threat, and penal populism literature, this dissertation examines the relationship between economic shifts, …

A Multifaceted, Non-Militarized Approach To Security Dynamics In Protected Areas: From Foot Patrols, To Tourism, And Local Communities, Monique Sosnowski

Dissertations, Theses, and Capstone Projects

A wide range of interventions have been implemented to reduce wildlife poaching incidents across the globe. These include community-based strategies, such as the development of alternative livelihoods; legal strategies, such as the development of legal frameworks at local, regional, and international levels; and wildlife law enforcement efforts, such increasing patrolling efforts. While community-based and legal strategies generally attempt to reduce the motivating factors surrounding the commission of crimes, wildlife law enforcement further attempts to prevent crimes from happening, assuming that someone will always be inclined. Given this inevitability, the question is raised regarding how to best reduce the occurrence of …

Weird Winter Weather In The Anthropocene: How Volatile Temperatures Shape Violent Crime, Christopher Thomas, Kevin T. Wolff

Publications and Research

Purpose: Current evidence suggests volatile temperatures are becoming more common because of climate change and can be expected to become even more frequent in the future. By focusing on recent temperature variability, we attempt to estimate one important dimension of the impact of climate change on violent crime. We also explore whether sudden upward temperature anomalies have stronger positive impacts on violent crime in the coldest months of the year, as routine activities are likely to change more drastically during this period.

Methods: This study explores the association between sudden temperature anomalies (both upward and downward) and the daily incidence …

A Statewide Analysis Of The Impact Of Restitution And Fees On Juvenile Recidivism In Florida Across Race & Ethnicity, Alex R. Piquero, Michael T. Baglivio, Kevin T. Wolff

Publications and Research

Whether the imposition of monetary sanctions is related to juvenile recidivism is explored overall and across race and ethnicity. Leveraging a statewide sample, logistic regression was used to predict fees and restitution assignment based on youth/case characteristics, hierarchical linear and logistic random-effects regression examined the association between neighborhood characteristics with fees and restitution, and propensity score matching examined whether fees and/or restitution are related to reoffending. No race/ethnic differences were found in the proportion of youth receiving court fees, yet when fees were administered both black and Hispanic youth received higher fees. Neighborhood characteristics have minimal impact on whether (or …

Mental Illness And Ethnic Identity And Their Relationship With Internalized Stigma Among Individuals Identifying As Latinx And Diagnosed With A Mental Illness, Melissa V. Martinez

Student Theses

Identity plays a key role in all matters regarding mental health, especially in experiences of stigma. Stigma, a term used to describe the processes of labeling and stereotyping of particular groups, has been shown to be a major contributor to mental health outcomes. Internalization of stigma, is an emotional and behavioral response that further affects an individual’s functioning beyond the effects of a mental disorder. The relationship between stigma and certain identities, such as gender, have been clearly demonstrated in prior research. However, identity is a complex concept that varies in meaning between individuals. The significance of a particular identity …

An Archival Exploration Of Lineup Fairness In Eyewitness Research, Phoebe Kane

Student Theses

In this study, we were interested in investigating if the Betaface facial analysis program reliably predicts eyewitness lineup choosing behavior. If face analysis programs are as good or better than human judgements, using them could be a reliably more efficient, reproducible, and equitable basis for choosing fillers and evaluating lineup fairness. We collected 27 datasets from eyewitness researchers and analyzed them to produce Betaface similarity values, which measured the similarity between all the photos in each array. We compared these Betaface data to the identification data from the original studies. Our analysis of the arrays via Betaface yielded data with …

Reclaiming Narratives Of Sexual Assault: An Examination Of The #Metoo Movement And Social Media, Katherine V. Marano

Student Theses and Dissertations

Untruths depicted by American media has shaped narratives about sexual assault and negatively affected the credibility of female sexual assault victims. Since women began the viral #MeToo movement in 2017, there is a need for research about the shifting sexual assault narratives in the United States. My project examines how this movement and use of social media has allowed women to reclaim narratives about sexual assault, spanning from October 2017 to April 2023. Specifically, my project analyzes ways in which the media responded to the #MeToo movement and how female created social media videos amplify sexual assault stories. I argue …

The Association Between Rape Myths And Continued Contact With The Perpetrator Following Sexual Abuse, Jainee Smith

Student Theses

Sexual violence is a widespread phenomenon. The term rape myth was first coined in 1980 by Martha Burt, and she defined it as “prejudicial, stereotyped, or false beliefs about rape, rape victims, and rapists” (Burt, 1980 p. 217). These myths, as well as any continued contact after a sexual assault, often lead to victim blaming, making it more difficult for victims to report any sexual assault. While rape myths were developed based on adult sexual assault, some research suggests that they also applied to child sexual abuse. This study will explore and expand the literature on rape myth acceptance and …

Metaperceptions Of Interactions Between Asian And African American Adults, Ariana Schlegel

Student Theses

In recent years, there has been a drastic increase in anti-Asian hate crimes in the United States, as well as news stories highlighting African Americans as perpetrators of anti-Asian hate crimes. As such, the paper focuses on how Asian Americans expect to be perceived by others, and how those expectations may change depending on the race (African American or White) and gender (male or female) of the conversation partner. A survey was created, which employed deception to have participants believe that they would have a short video conversation with somebody else about a political topic, and which randomly assigned each …

Juror's Perceptions Of Evidence-Based Suspicion, Nicholas Welter

Student Theses

Eyewitness misidentification is a leading cause of wrongful conviction. Although the prior probability of guilt (i.e., pre-identification evidence strength) is the most important factor for predicting a defendant’s actual guilt status and the accuracy of any subsequent eyewitness identification, no study has examined whether it affects juror decisions. This oversight is problematic because when officers place suspects in lineups when there is little evidence connecting them to the crime, it falls on jurors to examine the probative value of identification evidence. Participants (N = 357) watched a mock trial depicting an armed robbery that varied pre-identification evidence (strong vs. …

Seeking Justice For Jews From Mena Countries Through International Law: Comparing The Cases Of Morocco And Iraq, Jessica E. Yeroshalmi

Student Theses and Dissertations

Little is known of the Jews of Middle Eastern North African (MENA) origin whose long standing history in the region did not protect them from discrimination, persecution, and ethnic cleansing. Although much of the research on contemporary Jewish history and persecution revolves around the Holocaust and European events and its implications for Jews and international law, far less is researched about the uprooting of nearly one million Jews from the MENA region. In this investigation, I aim to reconstruct that narrative, applying international law to Jewish refugees from Arab countries. My thesis will be a comparative analysis of Morocco and …

Racialized Experiences Of Covid-19: Help-Seeking Patterns In Response To Racial Discrimination Among Asian American College Students, Jeeyun Lee

Student Theses

In the United States, reported anti-Asian hate crimes increased by 164% from 2020 to 2021, with New York demonstrating a difference of 223% (Center for the Study of Hate & Extremism, 2021). Ample evidence suggested its deleterious emotional impact; COVID-19-associated racial discrimination was found to be significantly associated with increased levels of mental distress, such as anxiety, depression, and PTSD symptoms (e.g., Hahm et al. 2021). With an aim of addressing the significant dearth of research on Asian Americans’ help-seeking behaviors in response to COVID-19-associated racism and distress, this study employed grounded theory to explore the experiences of 10 self-identified …

Public Perceptions And Punishment Of Sex Offenders, Emily R. Ives

Student Theses

Previous research has examined negative public perceptions and attitudes towards sex offenders and, in turn, how sex offenders are punished. The present study aims to build on previous research by examining whether perceptions of sex offenders are impacted by the offender’s relationship to the victim, and how victim perpetrator relationship may impact sentencing. Survey data from n=119 participants was examined. Participants were randomly assigned to one of three relationship conditions (i.e., stranger, acquaintance, or spouse) which was manipulated within a mock article vignette describing a rape incident. Subsequently, participants completed questionaries regarding sentencing of the described perpetrator, as well …

The Association Between Mental Health Diagnoses And Trial Competency Assessments In Defendants: A Meta-Analysis, Danielle C. Severe

Student Theses

In the realm of trial competency evaluations, there are a variety of methods used to evaluate whether an individual is fit to stand trial. Presently, forensic psychologists conduct trial competency evaluations in order to assess one’s ability to stand trial, but for persons with a mental health diagnosis, the generic competency measures are not the most effective means to assess one’s ability to stand trial, as mental health diagnoses impair cognitive functions that are required in judicial proceedings. Forensic psychologists have opted to utilize other assessment methods such as the MacArthur Competence Assessment Tool – Criminal Adjudication [MacCAT-CA] and Fitness …

The Effect Of Henna And Bleach Treatments On Cocaine Hair External Contamination, Alexandra Dombroski

Student Theses

Hair external contamination is a challenging phenomenon that may compromise hair testing interpretation. Previous research has found that cosmetic hair treatments can decrease concentrations of drugs that are already present in the hair shaft, however little is known about the impact of these treatments on the hair when the drugs are deposited externally. The aims of the present study were to explore how henna and bleach treatments influence cocaine external contamination. Sixteen authentic hair samples were collected from volunteers with varying hair colors and shapes and were confirmed negative for cocaine and benzoylecgonine by a fully validated LC-MS/MS method. Each …

Dynamic Risk Trajectories, Community Context, And Juvenile Recidivism, Kevin T. Wolff, Michael T. Baglivio, Jonathan Intravia

Publications and Research

Purpose

While the implementation of risk assessment has expanded, the extent to which there are different trajectories of risk/protective factors among adjudicated youth during supervision in the community remains unanswered. The goal of the current study is to identify the distinct trajectories in dynamic risk and protective factors among youth on probation and assess whether different patterns in risk over time are associated with continued offending.

Method

Group-based trajectory modeling is used to identify distinct trajectories across multiple domains of risk/need. The individual- and neighborhood-level factors associated with these trajectories are then explored, prior to examining their relationship to continued …

Shoplifting And Other Types Of Petit Larceny In New York City, Jeffrey A. Butts, Richard A. Espinobarros

Publications and Research

This data brief from the Research and Evaluation Center at John Jay College of Criminal Justice highlights recent trends in petit larceny in New York City, based on the latest police crime data. Thefts involving items valued under $1,000 have increased by 50% since 2006 and 29% since 2019. Between 2019 and 2022, incidents at major commercial retailers rose sharply by 53%, with drug stores and chain stores experiencing some of the most dramatic increases. While some types of petit larceny had been in decline prior to 2019, many surged again in the years following. These patterns suggest shifting dynamics …

'I Can’T Vote If I Don’T Leave My Apartment’: The Problem Of Residential Violence And Its Impact On The Politics Of Black American Women Living Below The Poverty Line, Alex J. Moffett-Bateau

Publications and Research

Prior research examining political behavior outside of the United States, has shown that violence can have a mixed impact on political engagement. Building on that work, this research examines whether violence shapes the political lives of poor Black women within the United States. I argue, neighborhood violence in the United States can and often does, shape the political behavior of Black women living below the poverty line in public housing. I use ethnographic data to parse out a conceptual framework which articulates connections between residential violence experienced by Black women living in poverty and their politics. Ultimately, my analysis shows …

Eddie Ellis, Credible Messengers And The Neo-Liberal Imagination Of Anti-Violence, David C. Brotherton

Publications and Research

I trace the socio-historical pathway of the concept of the credible messenger and related youth anti-violence interventions from the 1930’s to a more radically imagined iteration by Eddie Ellis in the 1980s. The focus shifts to its present-day iterations as I review two widely adopted anti-violence programs. I conclude that today credible messengers and anti-violence interventions are: (i) primarily imagined within a framework of neo-liberal possibility; (ii) valued for their contributions on individual and/or group behavioral change; and (iii) conceived in programs outside of any discourse on the structural roots of crime, collective agency, or the historical struggle for social …
