Evaluating A Test For Shedding Propensity Using Tape Lifts From Different Skin Locations, Xiao M. Chen

Student Theses

The shedding propensity of a person can assist data interpretation in casework when assessing the possibility of passive transfer for DNA analysis. Past studies on shedding propensity evaluated palmar skin (washed and unwashed) deposits. This study compared different skin locations with respect to shedding propensity, and explored the potential of tape-lifts as a skin surface collection method. Eight different skin types and samples were collected with adhesive tape disks from 28 participants over three non-consecutive days; the washed and unwashed fingers from both hands, toe, and arm, neck below ear, and nape. Samples were extracted, quantified, amplified, genotyped, and evaluated …

Reproducibility Of Individual Dna Deposits Detected Through Cellular Fluorescence, Natalee Small-Davidson

Student Theses

Contact traces are an important part of DNA casework, but the probative value of any identified associations depends on the possibility of passive transfer. There is known individual variation in DNA left behind during contact, this DNA shedding propensity has an effect on whose DNA is detected. This study evaluated this variability using a cell staining approach. Volunteers were asked to deposit a fingerprint on a clean glass slide, then wash their hands and deposit a second fingerprint after a 30-minute wait without touching anything. Three sets of samples were collected over three consecutive weeks. Fingerprints were stained with a …

Detecting Gsr Indicative Particles On Decayed Bones Using A Novel Field Kit, Sven Engling

Student Theses

Decomposed human remains are complex forensic puzzles, escalating in difficulty as the remains’ age obscures evidence, like trauma. Research has shown that scanning electron microscopes with energy dispersive X-ray spectrometers (SEM-EDX) are capable of detecting and identifying gunshot residue (GSR) particles on bones. However, SEM-EDX work is time consuming, expensive, and not accessible to every forensic department. Therefore, a preliminary field test capable of detecting GSR indicative particles, like lead, could save departments money and assist in trauma identification. This study examines the viability of using either the 3M Lead Check Test swabs or a sodium rhodizonate solution as part …

Memory Distortion For Footage Of An Emotionally Disturbing Police/Civilian Encounter: Investigating The Influence Of Bias And Trauma, Eric A. Korzun

Student Theses

Although body-worn cameras (BWCs) are expected to be objective tools for increasing police transparency and accountability, research refutes the idea that people can objectively view footage. Instead, research shows that people’s personal biases—for example, the extent to which people view the police like themselves, measured by the Identification with Police Scale (IPS; Tyler & Fagan, 2008) —shape how they view and interpret BWC footage (Jones, Crozier, & Strange, 2017). Additionally, studies of memory distortion reveal that people can come to remember traumatic events as worse than they originally experienced (Strange & Takarangi, 2012). Taken together, then, when viewing traumatic BWC …

A Preliminary Investigation Into The Effects Of Lucilia Sericata (Meigen) Blow Fly Larval Feeding On Sharp Force Trauma (Sft) Wound Patterns In Decomposing Bones Of Sus Scrofa Domesticus, Erica L. Klafehn

Student Theses

An important aspect of forensic investigations involves the characterization and analysis of bone related trauma as this can provide valuable information regarding the manner and circumstances of death. Bone trauma can be classified into three main categories, which include Sharp Force Trauma (SFT), Blunt Force Trauma (BFT), and Gunshot Trauma. Previous experiments have explored SFT on flesh and bones, specifically made with knives or saws, coupled with various microscopic analytical methods. Minimal research has been done integrating both a forensic entomology and forensic anthropology approach, so it is imperative to understand previous literature detailing the behaviors of insects (blow flies), …

Impact Of Blood Collection Tubes In Cannabinoid Quantitative Analysis, Tega E. Obruche-Akponah

Student Theses

In forensic toxicological cases, sample stability and storage are pivotal for obtaining adequate analytical results. Currently, limited information is available about the impact of different preservatives and anticoagulants present in the blood tubes used in the collection of blood samples containing cannabinoids. This study investigated the impact of sodium fluoride (gray top) and sodium citrate (blue top) blood collection tubes on the concentrations of tetrahydrocannabinol (THC), cannabidiol (CBD), cannabinol (CBN) and 5 THC metabolites (THC-OH, THC-COOH, THC-diOH, THC-glucuronide, THCCOOH-glucuronide) in whole blood samples, stored at room temperature, 4ºC and -20ºC for up to 3.5 months. The samples were extracted using …

The meat was burned over an open flame and the DNA was extracted using the Qiagen DNeasy Blood & Tissue Mini Kit, quantified with the NanoDrop, and amplified using the Bovine Genotypes Panel 3.1 Kit, and separated using the 3500 Genetic Analyzer. Profiles were analyzed using the Thermo Fisher Cloud Microsatellite Analysis software. The samples burned with the meat intact produced lower quantities of DNA than the bones burned with …

Waiting To Tell: Factors Associated With Delays In Reporting Sexual Violence, Lahiz P. Tavarez

Student Theses

In the United States (U.S.), 20% of women have experienced completed or attempted rape and 43.6% of women have experienced some form of contact sexual violence. Many instances of sexual violence go unreported to law enforcement – only 34% are reported to the police. Reporting can lead to more favorable outcomes for survivors since it is likely to increase access to medical care and mental health services and is an important step in order to hold perpetrators accountable, prevent future victims, and reduce the likelihood of longer psychological distress for the survivor. Delays in reporting are more prevalent in cases …

The Impact Of Covid-19 On The Thai Probation Department, Thanaphon Nunphong

Student Theses

The COVID-19 pandemic had a crucial impact on the Thai criminal justice system. While it may be true that the Department of Probation has proposed preventive and responsive measures in response to COVID-19, relatively little is known about the practical applications of these measures as well as the impact of COVID-19 on probation personnel, probationers, and parolees. The goal of this study is to explore the policies and practices of Thai probation agencies as they respond to the COVID-19 pandemic. This study surveyed probation officers in Thailand (N = 534; 60.6% Female) in March to April 2021, focusing on …

Support For Militant U.S. Foreign Policy: The Role Of Authoritarianism And International Xenophobia, Brandon M. Garcia

Student Theses

Right-Wing Authoritarianism (RWA) has been studied extensively in the domestic socio-political context, but its potential impact on foreign policy is still poorly understood. The current study replicated the putative two-factor model of the construct (Authoritarian Aggression/Submission and Conventionalism) and examined the associations of each factor with perceptions of overall danger to the U.S. posed by other countries and with the support for more militant U.S. foreign policy. As expected, both RWA factors correlated with self-reported levels of political conservatism (r = 0.32, r = 0.33; p < .001) Additionally, Authoritarian Aggression and Submission (but not Conventionalism) were correlated with increased perceived danger from foreign countries (r = .35; p < .001) and increased support for a more militant U.S. foreign policy (r = .25; p < .001). Participants higher in RWA were more likely to view the world as a hostile and threatening place, and in turn support more aggressive military action in response to those fears.

Effects Of Improper Ammunition Storage, Victoria S. Andre

Student Theses

Firearms are commonly used by law enforcement, hunters, and civilians either for protection, sport or criminal activity. Ammunition is used in traditional firearms such as rifles and handguns, and consists of a cartridge case, propellant, a bullet (projectile), and primer. The two types of priming systems within the cartridge that are commonly used today are rimfire and centerfire cartridges. There are several types of malfunctions that can occur with ammunition. Improper ammunition storage is one major factor that plays a role in ammunition failure. One form of improper ammunition storage is where the storage environment being used abruptly changes due …

Dosage Matters: What Is Dosage, Doyoung Kim

Student Theses

To reduce recidivism, many correctional programs and interventions have been introduced to offenders. Though, the rate of recidivism remains exceedingly high. To improve program outcomes, it is important to match the dosage of a program to risk levels. However, there is not a standardized definition and measurement of program dosage. This thesis extends the study on identifying the definition and measurement of dosage and the effectiveness of the programs by conducting a systematic review of prior research. The results indicate that as a treatment dosage, treatment duration was more frequently used compared to treatment intensity to reduce recidivism rate of …

Development And Validation Of A Method For The Determination Of Designer Benzodiazepines In Hair By Liquid Chromatography Tandem Mass Spectrometry (Lc-Ms/Ms), Laura C. Defreitas

Student Theses

In recent years, new designer benzodiazepines have become a challenge in forensic toxicology. These substances are analogues of the classic benzodiazepines, but their pharmacology is not well known, and many of them have been associated with overdoses and deaths. As a result, there has been a surge in efforts to develop ways to accurately test for these compounds in different biological matrices. This study focused to develop and validate a method for determining 17 new designer benzodiazepines in hair by liquid chromatography tandem mass spectrometry (LC-MS/MS). Hair samples were decontaminated, pulverized, and 20 mg of the sample was incubated in …

The Influence Of Demographic Information On Public Attitudes Towards Individuals Who Commit Sexual Offenses, Emily Bogdan

Student Theses

Research exploring the factors that shape public attitudes towards individuals who commit sexual offenses is needed to inform policy and reduce stigma that these individuals face as they reenter society. Prior research has explored demographic factors of those who offend and have been victimized, but few have studied how these variables may interact with one another to shape attitudes toward people who commit sexual offenses. The current study explores whether offender gender, victim gender, and victim age shape the public’s attitudes towards these individuals. Participants were presented with a vignette describing the offense and then they were asked to respond …

Sorption Of Metals At The Barite (001)-Water Interface, Inva Braha

Student Theses

Abstract

Ion desorption processes control the retention of ions, such as Pb²⁺, at barite surfaces, whereas ion adsorption processes are a likely initial step in the incorporation of divalent cations, such as Sr²⁺ and Pb²⁺, into barite. Based on previous studies on samples dominated by flat terraces with relatively few defects, Sr²⁺ and Pb²⁺ adsorb and incorporate at the barite (001)-water interface (Bracco et al., 2019; Bracco et al., 2020). Here, I measured how susceptible lead (Pb) is to desorption and the role surface variability plays in its sorption behavior. First, I measured …

Cocaine, Cocaethylene And Ethanol In Postmortem Blood Submitted To The New York City Office Of Chief Medical Examiner, Jada T. Alexis

Student Theses

Cocaine overdose deaths are on the rise in the United States. This increase may be due to the co-consumption of cocaine with other drugs. When cocaine is ingested in conjunction with alcohol, a specific metabolite called cocaethylene forms. Information regarding cocaethylene, specifically its interpretive value in post-mortem cases, has not been widely studied. Data from the Office of the Chief Medical Examiner in New York City revealed that there were 195 cases in 2017 positive for cocaethylene. These cases were most likely to involve black (42.1%) males (79.5%) in Manhattan (28.2%) aged 50 - 59 (34.4%). Most of the cases …

Stigma Towards Treatment Amongst People With Mental Illness, Haya M. Khan

Student Theses

There is evidence for the persistence of stigma towards people diagnosed with mental illness, as well as that endorsement of stigma is associated with reluctance to seek treatment. However, the process by which self-stigma impacts treatment choice amongst people with mental illness is not well understood. This study examined the impact of self-stigma on one’s decision to take medication or undergo psychotherapy; as well as the impact of stigma on choice of individual or group therapy. Surveys were administered through CloudResearch to 128 participants from the U.S, who reported a disorder diagnosed by a professional. The SSMIS-SF and ISMI-9 estimated …

Evaluating The 2019 New York State Bail Reform On Quality Of Life Offenses In New York City, Nodira Pirmukhamedova

Student Theses

Using the NYPD Complaint Data, this study compares the frequency of nine quality of life (QOL) misdemeanor complaints (n = 196,577) in New York City (NYC) before (n = 108,382) and after the 2019 NYS Bail Reform Act (n = 88,195), which eliminated cash bail for most misdemeanor crimes. The results show an overall decrease (18.6%) in nine QOL misdemeanor complaints in NYC after bail reform with a large effect (d = 1.317). The main limitation of this study is that it did not control for the impact of COVID-19 in 2020 on the criminal justice system’s shifting priorities. Another …

Bullet Ricochet Of Polymer Coated Bullets, Stephen Daly

Student Theses

Polymer coated bullets were designed to limit a shooter’s exposure to lead. However, despite the advantages that these bullets give there are still difficulties which arise in a forensic firearms examination. Unlike in a typical metal coated bullet, individualizing striations will typically not be imparted to a polymer coated bullet making it unable to be linked to a specific firearm. Due to this difficulty any information that can be gained at the scene of the crime could be crucial. Some obtainable information includes the angle of ricochet and the angle of incidence of the discharged bullet as well as traces …

They Should Know Better: Recognizing Sexual Grooming And Culpability Placement In Adolescents Versus Children, Taylor C. Smith

Student Theses

Sexual grooming is a process used by individuals in order to facilitate sexual abuse with a minor while simultaneously avoiding detection. As many sexual grooming behaviors are used before the perpetration of abuse, the identification of grooming behaviors is integral to child sexual abuse prevention. To date, few studies have researched the identification of sexual grooming behaviors utilized by child molesters and even fewer have examined the identification of those same behaviors utilized on adolescents. This study examined whether the age of the victim (child versus adolescent) affected how well someone can identify sexual grooming behaviors. Five hundred and forty-eight …

Investigation Of Postmortem Methamphetamine Cases Submitted To The New York City Office Of Chief Medical Examiner, Isaiah Jewell

Student Theses

Methamphetamine (N-methylamphetamine) is a central nervous system stimulant (CNS) and sympathomimetic drug with a high addiction potential. In the United States, there has been a significant increase in the presence of methamphetamine in recent years, specifically in the Northeastern region of the country. The New York City Office of Chief Medical Examiner (NYC-OCME) postmortem methamphetamine casework from 2018 and 2019 was analyzed and revealed that the presence of the drug increased drastically within a span of one year, jumping from 65 cases in 2018 to 99 cases in 2019. Males were overwhelmingly responsible for much of the casework, taking up …

Parental Plea Bargain Recommendations To Their Child In A Juvenile Court Setting, Aliya J. Birnbaum

Student Theses

This study examined parent acquiescence to attorney recommendations pertaining to plea bargain decisions, as well as whether this differed based on the racial similarity between an attorney and their juvenile client’s parent. Past research has shown that youth are vulnerable to the influence of perceived authority figures in a plea-bargain setting, leading them to rely heavily on the input of their parents and attorneys for how to plead. This study expands the literature to include how attorney race impacts parents’ plea decisions. A sample of parents of youth aged 11- 17 read a vignette, in which attorney race was manipulated, …

Weather And Crime: New York State, Yuna Kim

Student Theses

The present study assesses the degree to which temperature affects the crime rates in all 62 counties in the State of New York. Five different crimes (i.e., robbery, aggravated assault, burglary; larceny, and motor vehicle theft) for the year 2019 were selected from the Division of Criminal Justice Services of New York to be examined. The current study examined whether the rate of these crimes was associated with the changes in weather, with the assumption that higher weathers would lead to higher property and violent crimes, when controlling for the effect of various control variables. The findings suggest that the …

Sacred Music In Colonial Era Hispaniola: The Evangelization Of The Taino People, Tito J. Gutierrez

Student Theses

During the 15th-18th centuries, the major European religious orders; the Franciscans, Dominicans, Jesuits, and Jeronymites, journeyed to the newly colonized American territories in an attempt to convert the multitudes of natives peoples living there. Along with prayer books, crucifixes, and religious images, these missionaries brought sacred European music to American shores in an attempt to attract the native people to the Catholic faith.The use of music as a tool for conversion of native people in places such as Mexico, South America, California, and the South West United States, have been well researched and documented. However, the research of the spiritual …

Inclusivity In Children’S Services Within The School And Public Library, Phoebe Levin

Student Theses

The children's library has the potential to not only aid in knowledge-seeking conquests but to help establish a relationship of acceptance between the differences spewing from the child's own self, and the diversity of their peers. The increasing rate of underrepresented peoples in America, and the growing number of representative titles, have contributed to the trend of diversity and inclusivity in the library.

The efforts to make the library diverse and representative have been an ongoing struggle, yet in recent times efforts have proved that the exposure of diversity and inclusivity is beneficial to children. While examining how diversity and …

Relationship Between Race, United States Nativity, Perceived Discrimination, And Acculturation Stress, Simone N. Henderson

Student Theses

Acculturation has been defined as “changes that take place as a result of contact with culturally dissimilar people, groups, and social influences” (Gibson, 2001). This experience can cause stress for those experiencing it, especially when the individual is having a hard time adjusting to a new culture (Kim, 2019). One’s nativity, a person’s native-born status in their environment, and racial/ethnic group can also contribute to their experience of acculturation due to personal differences that these demographic variables create (Bondy et al., 2017; Hall & Carter, 2006). Studying race, nativity, perceived discrimination, and acculturation are essential for understanding the experiences of …

Disinhibition And Persistent Maladaptive Behavior, Angela T. West

Student Theses

Objective: There is an urgent need to reduce overpopulation in U.S. prisons, which are inundated with individuals needing substance use treatment. Research on both substance use and antisocial behaviors highlight maladaptive beliefs and behaviors, while also implicating disinhibition as an important factor. Disinhibition is a dynamic trait that can be targeted with therapeutic interventions. The current study explored the relationships between neurocognitive disinhibition, substance use, and recidivism among incarcerated men. The study hypothesized that disinhibition would be associated with history of substance use, history of antisocial behavior, and institutional misconduct, as well as predicting recidivism over and above history of …

Changes In The Black-White Sentencing Gap After United States V. Booker, 2008-17, Shuhao Zhang

Student Theses

The Black-White sentencing gap, as defined by the differences between the average sentences received by Black defendants and those by White defendants, is an under- research area. In the federal court, after United States v. Booker, this gap has decreased from 25 months in 2008-2010 to 0 in 2016-2107. By using Oaxaca decomposition, I find that the differences in criminal history, offense levels, and pretrial detention status between Black and White defendants are the main source of the gap. The unexplained portion of the gap, resulting from judges finding Black defendants more culpable to their offenses and thus imposing harsher …

Quantitative And Qualitative Assessment Of Interrogation Expectations, Shereen R. Lewis

Student Theses

Interrogation expectations (IE) is a construct that suggests expectations of custodial interrogations affect suspects’ Miranda waiver decisions while under interrogation. Prior research has examined IE quantitatively but there has been no prior research examining IE qualitatively. This current research conducted both a quantitative and qualitative analysis of IE using a sample of 335 participants from the United States. This research took the form of an online survey using Prolific (www.prolific.co) to recruit participants, Qualtrics (www.qualtrics.com) to record data, and SPSS and Nvivo to analyze quantitative qualitative data. It was hypothesized that substantial individual variation in IE will be found in …
