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, …

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 …

An Exploration Of Protein And Dna Components In Fingerprint Residue, Ashley Borrego

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 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 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 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 …

Language Access In Early And Late Spanish-English Bilinguals: An Erp Study, Lissete Gimenez-Arce

Student Theses

Research suggests that code-switching between two languages is possible because there is nonselective access to both languages, i.e., both languages are interdependent and stored in a shared lexicon. In this study, we used event-related brain potentials (ERPs) to measure the neural processes associated with language access, in particular, the ERP components: N200 and N400. Although previous studies have utilized these ERPs to investigate language access using interlingual homographs, i.e., words that look the same in two languages but have different meanings, these have focused on comparisons of monolingual and bilinguals. In contrast, we used a design that looked at Spanish …

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 …

Do Psychopathic Traits Influence Distractibility By Empathy-Eliciting Pictures?, Priya M. Reji

Student Theses

Empathy is a crucial component in forming interpersonal connections, and reflects the ability to share and understand the feelings of others. Psychopathy is often associated with a reduced ability to feel and display empathetic concern towards other people. The Response Modulation Hypothesis argues that such individuals have an attentional deficit, which makes it difficult for them to shift focus between stimuli, thus individuals who have high scores on the interpersonal-affective factor of psychopathy have an increased ability to ignore emotional stimuli that are goal-irrelevant. The current study investigated whether psychopathic traits would influence distractibility on an emotional Stroop (eStroop) task. …

Method Development And Validation For The Determination Of Designer Benzodiazepines In Blood By Lc-Ms/Ms, Victoria Mei

Student Theses

The misuse of designer benzodiazepines, as an alternative to prescription benzodiazepines and for drug-facilitated sexual assaults, has emerged as a growing threat, due in part to the ease of purchasing these drugs on the internet at low prices. Causing concern for safety, is the lack of dosage information resulting in users self-medicating, often leading to unintended overdoses, coma, or death at higher doses. With limited published data regarding quantification of designer benzodiazepines in forensic cases, a method was validated for the determination of thirteen and screening for two designer benzodiazepines in blood, in addition to a limited number of common …

Linguistic Features Of False Confessions And Confessions Not In Dispute: A Corpus Analysis, Lucrezia Rizzelli

Student Theses

Confessions are considered the gold standard of evidence, and yet many cases of false confessions causing wrongful convictions have come to the surface in the past decades. Currently, a method to identify false confessions does not exist and studies focusing on the content of the confessions have found similarities rather than points of distinction. In this study, we approached confessions from a stylistic rather than qualitative point of view, utilizing corpus analysis to outline the linguistic features of two samples of confessions: false confessions (n=37) and confessions not in dispute (n=98). Subsequently, we created a model …

Adults' Interpretation Of Children's Relative Temporal Judgments, Meghan Manginelli

Student Theses

Abstract

This study examined how adults interpret children’s relative temporal judgments about significant events. Previous research with children has shown that children have a “prospective bias,” when making relative temporal judgments. The impact of this bias within the context of eyewitness testimony is currently unknown, as no prior research has examined how adults interpret relative temporal judgments (i.e., are they also forward thinking). The present study examined this question. Adult participants were provided with mock attorney-child interactions during which a child witness (either 8 or 17 years old) gave relative temporal judgments (i.e., near, before, after) to …

Coercive Control In Long Term Sex Trafficking Relationships: Using Exhaustion To Control Victims, Nicole C. Bassil

Student Theses

The importance of coercive control tactics in maintaining women in commercial sex has been well-documented. Less known is how these tactics manifest in long-term relationships and how victims cope or react to establish patterns of control. The current study measured the temporal patterning of coercive control in long term sex trafficking relationships via wiretapped phone conversations between pimps and sex trafficked workers. In addition, victim responses of compliance versus resistance to coercive control tactics were measured. 68 phone calls over four months were transcribed and coded between two pimps and four women working in commercial sex. The findings indicate that …

Various initiatives to address the problem of gender-based violence have resulted in many countries attempting to quantify the extent of such crimes. The purpose of this present study is to examine nature and extent of GBV in India for prevention policy actions. The National Crime Record Bureau (NCRB) of India publishes a consolidated list of reported crime happenings in the country every year. Recognizing gendered aspect of certain crimes, the NCRB maintains a separate chapter on incidences of crimes …

The Forensic Analysis Of Adult Temporary Tattoos, Paige Cooper

Student Theses

Adult temporary tattoos have become more popular, yet there is very little research on them, especially regarding their use in forensics. This poses a problem because forensic investigators may not be able to distinguish a temporary tattoo from a real tattoo, possibly hindering their investigation. In this study, various types of adult temporary tattoos were examined and analyzed in attempts to identify and distinguish them, both from each other and from permanent tattoos. Infrared spectroscopy, specifically attenuated total reflection (ATR), proved to be more useful than ultra-violet visible light spectroscopy in terms of analyzing the samples. The natural adult temporary …

The Forensic Analysis Of Children's Temporary Tattoos, Erika Bravo

Student Theses

While children’s temporary tattoos have been produced since the 20th century, there are few scientific studies that have evaluated their physical and chemical characteristics. Therefore, this thesis is a preliminary study done to evaluate the composition of children’s temporary tattoos and consider the importance of such traces in a forensic content.

Colored regions in children’s temporary tattoos, such as red, pink, yellow and orange, were found to fluoresce with the use of an alternative light source while the use of microscopy led to the identification of different printing patterns between temporary tattoos. However, limitations in the ability to determine the …

Stop, Question, And Frisk: A Tool Of Racial Control In New York City, Justice D. Evans

Student Theses

Broken Windows policing through the utilization of Stop, Question, and Frisk has been widely used by the New York City Police Department (NYPD) since the 1990s, as guaranteed by landmark Supreme Court Case Terry v. Ohio (1968). As a result, hundreds of minority citizens have been the victim of routine stops for minor offenses through this aggressive police tactic. This study utilizes 2017 NYPD Stop, Question, and Frisk Data to determine whether broken windows policing, through stop, question, and frisk, operates as a mode of racial control for African Americans in New York City. Through the utilization of chi-square analyses, …

Simultaneous Determination Of Fourteen Antipsychotic Drugs In Whole Blood By Solid Phase Extraction And Liquid Chromatography Tandem Mass Spectrometry, Theresa M. Dawe

Student Theses

Anti-psychotic drugs are commonly prescribed to patients to treat several mental conditions, such as bipolar, schizophrenia, and manic-depressive disorder. The analysis of anti-psychotic drugs in blood is a common practice in clinical and forensic toxicology, to monitor drug treatment (therapeutic drug monitoring) or to explain the cause of the impairment or intoxication in human performance and in postmortem cases. However, most of the current studies have been performed in plasma, and a limited number in blood. We developed and validated a method to confirm and quantify a panel of commonly prescribed anti-psychotic drugs in whole blood using solid phase extraction …

Fight, Flight, And Free Will: How Knowledge Of Biopsychosocial Effects Of Trauma Influence Free Will Beliefs And Punishment For Juvenile And Adult Offenders, Rachel Lazar

Student Theses

Justifications for punishment are generally grounded in retribution or consequentialism. Retribution presupposes a belief in free will, claiming that offenders freely and rationally choose to commit a criminal act, and are therefore deserving of punishment. Consequentialism does not necessitate a reliance on free will, and views punishment as means to a valuable end. In recent years, neuroscientific research has challenged the notion of free will, providing one pathway for a public shift away from retribution and towards consequentialism. However, methods by which to instill this doubt in laypeople are still being discovered. To date, no studies have attempted to instill …

The Dud Effect: The Effect Of Dissimilar Fillers In Eyewitness Lineups, Shannon Booth

Student Theses

Similarity and confidence are often analyzed in relation to eyewitness accuracy. Duds, highly dissimilar fillers, can impact an eyewitness’ accuracy and confidence. This study analyzed the impact of duds, similarity and accuracy in the context of lineup bias. This study found that in target-absent conditions there is a significant positive relationship between lineup bias and confidence. This study also found that highly similar lineups results in a lower proportion of correct identification, even in highly confident witnesses, compared to medium similar and low similar lineups. Further research should look closer at the “sweet spot” of similarity in order to advise …

Developing And Validating A Fast And Accurate Method To Quantify 18 Antidepressants In Oral Fluid Samples Using Spe And Lc-Msms, Sanghee S. Shin

Student Theses

Antidepressant drugs are one of the most widely used medicines for treating major depressive disorders for long time periods. Oral fluid (OF) testing offers an easy and noninvasive sample collection. Detection of antidepressants in OF is important in clinical and forensic settings, such as therapeutic drug monitoring and roadside testing for driving under influence. We developed and validated a comprehensive liquid chromatography tandem mass spectrometry method for 18 antidepressants (amitriptyline, bupropion, citalopram, clomipramine, cyclobenzaprine, desipramine, desvenlafaxine, doxepin, duloxetine, fluoxetine, imipramine, mirtazapine, nortriptyline, paroxetine, sertraline, trazodone, trimipramine, venlafaxine) in oral fluid collected by Quantisal® oral collection devices. 0.5 mL of Quantisal® …

Examining Witness Testimony In Domestic Homicides, Hana Chae

Student Theses

The present study investigated the effects of varying witness testimony on mock jurors’ perceptions of a case where a woman utilizes self-defense as a reason for killing her husband during a domestic dispute. A 3 (expert witness) x 3 (child witness) design was used to examine the effects of two different forms of expert testimony (Battered Woman Syndrome [BWS] & Social Agency [SA]) and its interaction with presence of child witness [age 5 & age 8]. Jury eligible participants (N = 245) were recruited from Amazon Mechanical Turk (MTurk). It was hypothesized that the presence of an expert witness would …
