Examining The Impact Of Competency To Stand Trial And Judicial Instructions On Ngri Verdicts, Erin K. O'Donnell

Student Theses

Objective: The current study tests whether jury-eligible adults follow judicial instructions to disregard information about a defendant’s pretrial competency status when deciding whether he is guilty or not guilty by reason of insanity. Hypotheses: It was anticipated, because of the effects of hindsight bias, that defendants who were previously found competent to stand trial would be less likely to be found NGRI than a defendant who previously was deemed incompetent but has been restored to competency for trial. We also predicted that judicial instructions to disregard pretrial competency status would not effectively eliminate the effect of competency status without an …

The Influence Of Prison Sentence Length On The Societal Dehumanization Of Ex-Offenders, Skye Jensen

Student Theses

The current study examined the factors that influence the societal dehumanization of offenders, belief in offender redeemability, and support for resource allocation and offender re- enfranchisement. Specifically, the study investigated how prison sentence length influences public opinion on these measures. Two hundred and twenty-two individuals participated in this study and were randomly assigned to one of two conditions involving their responses to a vignette depicting an offender having served either five or 15 years. The results revealed that the length of the offender’s prison sentence did not impact participants’ dehumanization of offenders, belief in their redeemability, or support for reentry …

Not All Videos Are Created Equal: Camera Perspective Bias And Video-Recorded Eyewitness Identification Procedures, Kelsey N. Doherty

Student Theses

Video-recorded eyewitness identification procedures can preserve an accurate record of the conditions under which the eyewitness made an identification. Scholars posit that having the record will allow legal actors to make better decisions on the basis of an identification. Yet limited research has examined how jurors’ judgments are influenced by this evidence. Research on other types of video-recorded evidence has demonstrated a strong camera perspective bias, wherein jurors’ judgments are influenced by the angle with which the evidence is recorded. This study examined whether the camera perspective bias similarly influences jurors’ perceptions of video-recorded identification procedures. Participants viewed a mock …

Digilantism, Discrimination And Punitive Attitudes. A Digital Vigilantism Model, Sebastián A. Galleguillos

Student Theses

In this article, I propose and apply a digital vigilantism model to a specific incident that occurred in Mexico, where the death of two innocent people was filmed through Facebook Live. Using a mixed methods approach and content analysis, I analyzed digilante Facebook posts (N=942) coding gender, digital vigilantism categories, discriminatory comments, and punitive attitudes aimed at the perpetrators and the inciter of the lynching. The categories include investigating, blaming, or rebuking, while the discriminatory comments include classism, racism, homophobia, and body-shaming. I coded the punitive attitudes distinguishing four categories: non-physical punishment (calling for God’s wrath and the guilty conscience …

Substance Use, Neurocognitive Deficits, And Criminal Recidivism, Emily H. Kim

Student Theses

Many offenders demonstrate substance use and neurocognitive impairments. Substance use directly impacts executive functioning due to poor impulse control, leading to impaired decision- making. Substance use and neurocognitive deficits also contribute to recidivism. Incarcerated individuals with substance use disorder have higher rates of recidivism, and executive dysfunction has been shown to contribute to recidivism due to low behavioral inhibition skills and deficiency with cognitive flexibility. There is a discontinuity in literature, however, since many studies only investigate either substance use or neurocognitive deficits to predict recidivism. However, it is important to examine the interaction of these factors to predict future …

The Relationship Between Traumatic Brain Injuries, Impulsivity, And Crime, Brian Ramanauskas

Student Theses

The rate of traumatic brain injuries (TBIs) are increasing each year, impacting an estimated 1.4 million Americans. After further investigation, researchers have concluded that 8.5% of the general public sustains at least one TBI, whereas this number ranges from 25% to 87% in criminal populations. In the literature, impulsivity is frequently described as poorly conceived, prematurely expressed, or inappropriate behaviors. Additionally, poor impulse control has been shown to significantly impact the likelihood of criminal activity, increasing the rate of recidivism. The current study examined an archival dataset of 95 incarcerated individuals from a private correctional facility in a large mid-Atlantic …

The Language Abilities Of Justice-Involved Adults, Talaya Patton

Student Theses

This study explores the relationship between language abilities and involvement with the justice system across the lifespan. Previous research has demonstrated a significantly higher prevalence of language impairment in juvenile justice populations, relative to the general population. These language impairments have been found across both expressive and receptive abilities, often previously undiagnosed.Further, juvenile justice involvement is a well-established predictor for later adult criminal behavior.However, no studies to date have explored the effects of language abilities and juvenile justice involvement on future outcomes, namely continued justice involvement in adulthood. The current study utilizes archival data on 95 incarcerated men to analyze …

Reporting Of Sexual Assault And Abuse Of Males In The Ultra-Orthodox Jewish Community, Yevgeniy Pastukhov Semchenkov

Student Theses

This study explores religious, societal, and intrafamilial factors that prevent Ultra-Orthodox Jewish male survivors of child sexual abuse from reporting the incidents. Five men were recruited and participated in in-depth interviews. The findings indicate that child sexual abuse in Ultra-Orthodox Jewish communities was and is underreported. The factors that were identified as influential on the reporting decisions included religious rules and regulations, lack or deficient sexual and legal education, and communal and intrafamilial efforts to silence a child and cover up the abuse. The results link the religious and educational background of male survivors of sexual abuse and their reporting …

Analysis Of Cannabinoids In Serum By Gc-Ms/Ms, Christie Cannarozzi

Student Theses

Due to recent changes in federal and state legislations, the availability and consumption of cannabis products have increased in the United States. The expanded use of recreational and medicinal cannabis products increases the importance of implementing sensitive and selective instrumental methods in toxicological laboratories, as legal implications may arise in forensic cases, such as driving under the influence of drugs (DUID). The purpose of this study was to perform a cross-validation for the quantitative analysis of cannabinoids (Δ9-tetrahydrocannabinol, cannabidiol, cannabinol, 11-hydroxy-Δ9-tetrahydrocannabinol, and 11-nor-9-carboxy-Δ9-tetrahydrocannabinol) in serum by gas chromatography coupled to triple quadrupole tandem mass spectrometry (GCTQ). This method was fully …

Discrimination Of Monozygotic Twins Using Dna Methylation Levels Of One Cpg Site At Chromosome 3, Dino O. Robinson

Student Theses

Conventional STR typing, commonly used in forensics for human identification, poses a problem in criminal cases and paternity disputes involving monozygotic (MZ) twins because they share identical DNA sequences. To date, no routine method is available in forensics to differentiate between individuals of MZ pairs. Recently, epigenetic methods measuring differential DNA methylation patterns have been applied to MZ twin differentiation. In this study, we investigated the potential to identify MZ twins using a previously identified DNA methylation site in chromosome 3, cg18562578, in a sample of 129 MZ and 37 dizygotic (DZ) twin pairs. We used bisulfite converted saliva DNA …

Discrimination Of Soil Organic Matter Using Nuclear Magnetic Resonance In Conjunction With Principal Component Analysis, Victoria G. Hsieh

Student Theses

The characterization of trace evidence is key to the field of forensic science. Trace evidence can take many forms, such as glass, fiber, and soil. Traditionally, forensic soil analysis has been painted as one of the more tedious applications, which conventionally studies the mineral composition of soil samples. In this study, we present another avenue of soil analysis that takes advantage of understudied factor of soil: soil organic matter (SOM). Using both proton (¹H NMR) and carbon nuclear magnetic resonance (¹³C NMR) separately and applying principal component analysis (PCA) to both types of spectra, we sought …

Student Theses

The current use and misuse of synthetic and prescription opioids in the US has reached epidemic status. According to the US Department of Health and Human Services, every day more than 130 people in the US die after overdosing on opioids, and 2.1 million had an opioid use disorder in 2016. Hair is becoming an alternative matrix of increasing interest in forensic toxicology to investigate drug use and abuse patterns due to its long window of detection. The focus of this project was to develop and validate a method that simultaneously detects and quantifies 27 classic, prescription and synthetic opioids …

Paraphilias: A Survey Of Experts, Cecilia Allan

Student Theses

There is limited research examining the processes utilized when making diagnoses in sexual offender civil commitment (SVP) evaluations. The purpose of this research was to examine mental health professionals’ (MHPs) opinions towards, and use of, paraphilic diagnoses in SVP evaluations. In particular, other-specified (OS) paraphilic diagnoses of hebephilia and nonconsent were examined. Results indicate a lack of understanding among MHPs regarding how to recognize and apply OS paraphilic diagnoses. Findings also provide insight into how and why MHPs choose to diagnose OS paraphilias, demonstrating a high level of reliance on documentation. Results indicate the existence of an adversarial allegiance among …

The Tipping Point In Psychopathy: Role Of Psychopathic Traits In Trauma Exposure, Sneha M. Gupta

Student Theses

Though psychopathy has been associated with a socially deviant lifestyle, the idea of “successful” psychopathy has gained increased attention. Previous research has explored whether psychopathic traits play a role in trauma exposure/ PTSD, using clinical and forensic populations. Results from these studies suggest that Factor 1 traits may protect from trauma exposure (Factor 1 Theory) while Factor 2 traits may worsen the impact of trauma through exacerbated exposure to traumatic events. The objective of this study was to explore the relationship between each of Factor 1 traits and Factor 2 traits with trauma exposure and PTSD. In a sample of …

Student Theses

Domestic violence has continued to be a major global issue effecting many if not all countries in the world. The form domestic violence can take varies from country to country. Laws protecting women from domestic violence also differs as a result This research examines how cultural differences impact domestic violence legislations in the United States and the Republic of India. India was chosen as a comparison jurisdiction because of differing demographics and possible variables in that country.

The primary data source for this study were the numerous enacted legislations pertaining to domestic violence that form the legislative landscape on domestic …

Examining Mental Health Stigma Among Police Officers And Intended Behavior Towards People With Mental Illness, Sara Soomro

Student Theses

This research examines where or not stigma about mental illness exists among police officers in the United States and whether it shapes their attitudes about seeking mental health. It has been estimated that police officers have a prevalence rate of 13%, while the general population has a prevalence of 4%. Given the increased exposure to trauma, police officers are still unlikely to seek professional help. Moreover, police officers are first responders to incidents involving individuals with a mental illness and are often tasked with playing the role of a mental health professional. This study further examines how stigma effects intended …

Effects Of Mercury On The Dopamine Transporter Cell Surface Expression In Pc12 Cells, Christina Hui

Student Theses

Environmental factors, such as heavy metal exposures, have been suggested to have an impact not only on neurodegenerative disease, such as Parkinson’s disease, but also on psychostimulants abuse and their toxicity. In this study, two questions were addressed: 1) effects of mercuric chloride on parkinsonian toxicant 1-methyl-4-phenylpyridinium (MPP⁺) induced cytotoxicity and 2) effects of mercuric chloride on cell surface dopamine transporter. Pheochromocytorma cells (PC12) were treated with various concentrations of mercuric chloride (0.02~2.0 ppm) for 4 hours with and without 0.1 mM MPP⁺. Significant potentiation of toxicity was observed when there was co-treatment with 0.5 ppm …

Evaluation Of A Novel Dna Collection Matrix Designed To Improve Recovery Of Touch Dna From Non-Porous Surfaces, Eric Ramirez

Student Theses

The collection of touch DNA from evidence has been a challenge in the field of Forensic Biology for decades. There are numerous collection protocols, substrates, and solutions that have been used to varying levels of success. Currently, no single method or substrate stands out as the single most effective collection protocol. The Gene Link Omni Matrix™ K105 solution is a novel collection method that can be sprayed onto the surface of non-porous evidence. The matrix dries into a film, capturing cells and cell-free DNA which can be scraped off and collected into a tube. During extraction, the matrix dissolves into …

Dna Mixture Statistics Using A Likelihood Ratio Software Tool: Effect Of Variations In Drop-Out Rates And Number Of Contributors, Felicia M. Lucero

Student Theses

Complex DNA mixtures can be very probative evidence, but comparisons to a person of interest can be affected by allelic drop-out and uncertainty regarding the number of individuals having contributed DNA to a sample. Scientific organizations such as the International Society of Forensic Genetics (Gill et al., 2006) recommend that likelihood ratios should be used to provide a statistical weight when a positive association is made between the DNA profile of a person of interest and an evidentiary DNA sample. To this effect the New York City Office of Chief Medical Examiner (OCME) developed a software program, Forensic Statistical Tool …

Relationship Between Childhood Relationships And Antisocial And Lifestyle Characteristics Of Psychopathic Traits, Esther Kim

Student Theses

Psychopathy is a heterogeneous personality construct that has long been associated with antisocial behaviors and outcomes (Hare, 2003; Walsh & Kosson, 2006). However, some literature suggests that socially deviant behaviors and outcomes may not necessarily be a fundamental component of psychopathy (Cooke & Michie, 2001; DeMatteo, Heilbrun, & Marczyk, 2001; Lilienfeld & Widows, 2005). Research on externalizing behaviors and psychopathy has broadened from examining the quality of early relationships as a risk factor (Salekin & Lochman, 2008), to also examining early relationships as a potential protective factor against the development of psychopathic characteristics and antisocial outcomes (i.e. Backman, Laajasalo, Jokela, …

Development Of Multiplex Pcr Assay As A Basis For Predicting Pigment Related Features, Stephanie A. Rodriguez

Student Theses

Currently, short tandem repeats are used in forensic DNA typing to identify the DNA profiles recovered from evidence samples and deceased individuals. Recently, SNPs that are related to pigmentation have been researched for their use in the identification of phenotypic traits. The development of a SNP panel that could successful identify the eye and skin color of an individual, would be immensely useful in missing person cases or mass disaster victim identification. Eight SNPs were selected into a SNaPshot assay that could accurately predict eye and skin color, five for eye color and six for skin color. Development of the …

The Feedback Effect: Does Exposure To Interviewer Feedback Affect An Observer's Perception Of Veracity And Guilt?, Kayla A. Harrod

Student Theses

Historically, assessing deception has been rooted in the belief that a guilty suspect displays signs of anxiety. Based on a suspect’s physical demeanor and other behavioral cues presented during an interrogative session, law enforcement personnel (LEP) will utilize a set of techniques to elicit information about a crime. One such technique is the administration of feedback, which is the verbal assessment of a suspect’s guilt. The issue that stems from administering feedback lies not only in how it is given but also how it is received and interpreted by others. In a two-part study, the possibility of a “Feedback Effect” …

A Microspectra Analysis Of Synthetic Wig Fibers, Jaclyn R. Beshlian

Student Theses

The goal of this study was to determine whether differentiation between 20 visually similar light brown synthetic wig fibers was possible with the use of a microspectrophotometer (MSP). Visually similar fibers were chosen to display the power of the instrument over the human eye. An MSP is an instrument that has the ability to aid in the analysis of certain microscopical samples. With this particular instrument one is able to collect the absorption and fluorescence spectra of microscopical colored samples without destroying the piece of evidence itself. Prior to any analysis with the MSP, the material of the fibers was …

Dna Recovery From Handwritten Documents Using A Novel Vacuum Technique, Patrick M. Mclaughlin

Student Theses

Investigations of many crimes such as robberies, kidnappings, and terrorism are often associated with the recovery of a paper document which has been written by the perpetrator. Paper can provide a variety of forensic evidence such as DNA, latent fingermarks, and indented writing. The focus of this study was the collection of probative DNA profiles from the text region of a handwritten note through a vacuum suction device without altering or destroying the document. Collection of DNA evidence was carried out in two separate groups. The first group involved 11 volunteers providing a handwritten note sample with unwashed hands. The …

Student Theses

The main focus of this project was to investigate the protein and DNA components in both sebaceous and eccrine fingerprints. This study investigated the relative content of DNA and proteins in eccrine fingerprints to sebaceous fingerprints. All volunteers were instructed to wash and dry their hands prior to depositing parallel thumbprints. Twenty volunteers were instructed to touch their face to produce sebaceous prints, and 5 volunteers were instructed to wear gloves over a heat source to produce sweaty or eccrine prints. Microscopy was used to score the cellular debris of the right fingerprint on a scale of 1-4 based on …

The Role Of Eyewitness Confidence And Prosecution/Defense Presentation In How Facial Composites Shape Juror Decision-Making, Rebecca E. Singh

Student Theses

Eyewitness testimony has been found to be an unreliable form of evidence (Loftus, Miller & Burns, 1978; Oswald & Coleman, 2007; Wells & Hasel, 2007; Loftus & Greenspan, 2017; Jaross, 2018; Wade, Nash, & Lindsay, 2018; Wixted, Mickes, & Fisher, 2018). Yet, this evidence is still used in the courts today, and, in fact, is perceived by jurors as important and compelling in comparison to other case factors (e.g., character evidence, physical evidence; Topp-Manriquez, McQuiston, & Malpass, 2014; Kabzińska, 2015). Additionally, eyewitnesses are sometimes requested to help create a facial composite of the suspect and, critically, these composites are then …

The Impact Of Client's Gender And Culture On Service Providers Strategies In Diversion Programs, Stephany Betances

Student Theses

Despite the growing rate of adolescent girls in the criminal justice system, there has been little institutional support for empirically supported programs tailored for girls (Matthews & Hubbard, 2008). There is a similar substantial lack of culturally specific programming. Problematically, both constructs have been found to impact treatment (Bright & Jonson-Reid, 2010; Matthews & Hubbard, 2008). This qualitative study utilized grounded theory principals to investigate the impact of gender and culture on the therapeutic relationship for justice-involved youth in seven alternative-to-incarceration agencies in New York City. Elicited themes focused on both recommended strategies and continued challenges. Results indicated that while …

The Impact Of Cannabis Use On Generalized Anxiety Disorder, Dylan James Tellez

Student Theses

Cannabis is the most commonly used illicit substance in the world (United Nations Office on Drugs and Crime, 2018). Despite past criminalization, various states have begun to decriminalize cannabis for recreational and medical use; however, research on the effect of cannabis use on mental health is divided. Research on specific mental health disorders, like generalized anxiety disorder (GAD), and cannabis use is lacking. This study aimed to understand whether cannabis use affected individuals likelihood of meeting criteria for GAD by using a nationally representative longitudinal dataset. Results indicated that the inclusion of cannabis use did not explain additional variability in …

Development Of A Screening Method For Drugs Of Abuse By Direct Analysis Of Dried Urine Spots Coupled To Mass Spectrometry, Melanie Goldstein

Student Theses

Fast and easy screening procedures are essential in any forensic toxicology laboratory to differentiate negative samples from presumptive positive cases. Immunoassay techniques, such as enzyme multiplied immunoassay technique (EMIT), are routinely employed as screening procedures. However, these techniques lack specificity (only differentiate group of drugs and not individual compounds) and it is difficult to add new compounds to the panel. Direct analysis of dried urine spots (DUS) by mass spectrometry (MS) offers a novel strategy to overcome these issues. DUS offer an improved storage alternative for biological samples, reducing costs and space requirements. In this work, an original method to …

911 Dispatchers: Investigating Their Knowledge Of Eyewitness Evidence Collection, Samantha A. Kosziollek

Student Theses

911 dispatchers are often the first contact in an emergency, playing a critical role in the investigative process. Presently, a new bill is seeking to nationally reclassify these communications officers, recognizing them as vital first responders, as their initial collection of eyewitness evidence aid in the attainment of crucial information and detailed descriptions of an accident or crime. However, only one study (Kassis, 2017), to date, has examined the training of 911 dispatchers, as well as their self-reported knowledge of the potential influences their language could have on an eyewitness’ memory. While this research highlighted disparities between the perceived role …
