Functional Isolation: Understanding Isolation In Trafficking Survivors, Liz Mahan

Student Theses

This study examined how traffickers used different elements of isolation and how such tactics may have contributed to the traffickers’ success in maintaining control over the victim. I examined in-depth narratives from 14 women between the ages of 20-53, primarily immigrants, who were recruited from an agency serving victims of sex trafficking in a large metropolitan city. The tactics used by traffickers varied and included not only the commonly defined structural isolation in which victims are restricted physically and socially, but also included a shrinking of safe social space and an elimination of privacy and social support. The latter is …

Non-Contact Sex Offenders And Public Perception The Importance Of Victim Type And Crime Location, Chelsea Gold

Student Theses

It is estimated that 10% of Americans will be the victim of a non-contact sex offense in their lifetime. Non-contact sexual offenses include unsolicited exposure to sexual situations, verbal and behavioral sexual harassment, threats, and unsolicited use of a person’s image in a sexual manner. This study will specifically look at exhibitionism, voyeurism, and frotteurism. Historically these sex crimes have been considered nuisance behaviors, however, some recent research suggests that these crimes may negatively impact the victims. This study experimentally examined people’s perceptions of non-contact sex offenses and the type of consequences that should be incurred for these crimes. Further, …

Digital Anti-Forensics: An Implementation And Examination, Stephanie Dachs

Student Theses

The rise of computer use and technical adeptness by the general public in the last two decades are undeniable. With greater use comes a greater possibility for misuse, evidenced by today’s incredible number of crimes involving computers as well as the growth in severity from that of cyber hooliganism to cyber warfare. Although frequently utilized for privacy and security purposes, the vast range of anti-forensic techniques has contributed to the ability for hackers and criminals to obstruct computer forensic investigations.

Understanding how anti-forensics may alter important and relevant data on an electronic device will prove useful for the success and …

A Cross-Cultural Examination Of The Conformity Effect When Co-Witnesses Discuss A Crime, Sungil Bang

Student Theses

Prior research has shown that discussions with a co-witness can lead to the spread of false information, better known as the memory conformity effect. Specifically the effects of independence and interdependence on memory conformity have been examined. People who perceived their selves as a distinctive and unique were related to less memory conformity whereas those who identified themselves within their social relationships were not related to memory conformity. One of the limitations of the previous study is that they only focused on Western populations even though there is a cultural difference between Western European culture and Eastern Asian culture in …

Range Of Detection For Proteins And Dna From Fingerprints On Fired And Unfired Cartridge Casings, Stacey-Ann R. Sterling

Student Theses

Cartridges and spent cartridge casings can be probative pieces of evidence. Unfortunately due to a combination of factors such as exposure to high temperatures and initially low amounts of biological material on the surface, DNA testing so far has been mostly unsuccessful for these items. Typing other marker systems, such as protein polymorphisms, on the same biological evidence would add power of discrimination. To explore this option we developed a DNA-protein trypsin-based co-extraction method that was optimized for unfired and fired cartridges. Various sample wet and dry collection methods and multiple metal casings, such as aluminum, nickel, steel, and brass …

Are Dhs Technology Grants For Local Police Departments An Effective Tool Against Terrorism?, Erika Mcginty

Student Theses

This paper examines the effectiveness of allocating funds to the nation’s police departments for the prevention of domestic terrorism, as is done annually through the Department of Homeland Security’s Homeland Security Grants Program. The program, administered by the Federal Emergency Management Administration, has distributed billions of dollars since its 2003 inception in equipment, software, and technology services based on the recipient police agencies’ own risk assessments of local terrorism. Much of the technology desired by police consists of systems of mass surveillance; this thesis focuses on implementations of surveillance video cameras or CCTV, license plate readers, and unmanned aerial vehicles. …

Optimizing A Method For Simultaneous Recovery Of Proteins And Dna From Fingerprints, Steven Kranes

Student Theses

DNA testing on touched objects is a valuable tool in forensic investigations, but DNA is usually present in low amounts, causing poor STR typing results. For touch DNA evidence, there is a clear need for additional individualization, especially for highly probative samples. This could be achieved by testing genetically variable proteins. The goal of this project was to develop a DNA/protein co-extraction method to facilitate DNA and protein testing on the same evidence item. Existing DNA extraction methods were carefully adjusted to allow for downstream mass spectrometry analysis. Initial experiments on saliva and fingerprints placed on glass suggested that trypsin …

The Divinity Of Crime: How Spirituality Can Strengthen The Resilience Of Criminal Organizations, David R. Vegvari

Student Theses

This thesis conducts a systematic analysis of open source data that discusses ideational factors of resilience in criminal organizations. It does this by looking at the role of spirituality – referred to as an individual’s moral or ethical codes influenced by cultural, ethnic, and religious values – and its effects on an organization’s durability, impenetrability, and adaptability. To understand spirituality as a factor of resilience in criminal organizations, it is delineated into four Dimensions of Spiritual Influence (DoSI). They are (1) trust, (2) spiritual neutralization, (3) strategic arenas, and (4) the logistical use of spiritual institutions. In order to analyze …

Interrogation Techniques In South Korea: What Happens In A Korean Interrogation Room?, Hyunjoo Lee

Student Theses

Recently, South Koreans have realized that, due to the techniques used during police investigations, suspects might often commit suicide or confess to crimes that they did not commit. Unfortunately, many studies in Korea are retrospective with regard to false confessions (i.e., case study), and no systematical research studies have been conducted on how Korean police officers interrogate suspects. To prevent events in which potentially guilty suspects are treated inhumanely and innocent suspects falsely confess, self-reported surveys were administered to 86 Korean police officers to systematically analyze how Korean police officers prepare for interrogations (e.g., interrogation training session attendance), how they …

"Why Wouldn't You Like It?": Exploring Masculine Identities In Discussions Of Male Rape, Bridget Woods

Student Theses

Empirical research on the topic of male rape is scarce within the discipline of psychology. Current research focuses on negative perceptions of male rape victims, but does not take into account the role hegemonic masculinity plays in constructing beliefs about male rape. The present study aims to gather narratives of young men’s beliefs of male rape and male rape myths and analyze how masculinity and masculine identities shape these beliefs. Narratives were gained through collection of journal writings and focus groups, and an integrated narrative analysis was conducted to identify themes and discursive strategies that men employed to balance their …

Procedural Justice And Citizen Compliance: Police Officer Demeanor And Crime Severity, Shiny Sharma

Student Theses

Little is known about how police officer demeanor impacts citizen compliance under specific conditions such as the severity of a crime. Using a sample of 141 college students, we randomly assigned vignettes that manipulated crime severity type (e.g., petty theft or armed robbery) and police officer demeanor (e.g., procedurally just or not procedurally just) to gain a better understanding of this nuanced relationship. Participants were more likely to report suspicious behavior, regardless of crime severity, if the officer demeanor was procedurally just. Additionally, participants were more likely to consent to a search and report a suspicious person in the procedurally …

Risk And Prevalence Of Personality Disorders In Sexual Offenders, Allison Sigler

Student Theses

Studies suggest that about seventy percent of incarcerated sexual offenders have been diagnosed with a mental disorder, with about fifty percent meeting diagnostic criteria for a personality disorder. Personality disorders have been shown to increase the risk of recidivism in offenders overall. However, little is known about how a personality disorder diagnosis increases this risk for sex offenders. The current study aims to evaluate the prevalence of personality disorders in sexual offenders, whether this varies by offender type, and how these relate to recidivism risk. Archival records from a large sample of convicted sex offenders who were incarcerated in a …

Hindsight Bias In Clinical Decision Making, Amanda Beltrani

Student Theses

The tendency for an individual to believe that a specific event, in hindsight, was more predictable than it was in foresight is known as hindsight bias. This phenomenon has been demonstrated in the psychological literature across a variety of samples, methodologies, and predictions for decades. The current study used a sample of 95 mental health professionals to explore the impact of advanced outcome knowledge on the decision making process. Participants reviewed a hypothetical risk assessment in the form of a hospital chart and then responded to a series of questions, using only their clinical judgment. Analyses revealed that evaluators who …

Post-9/11 Media Coverage Of Terrorism, Zachary S. Mitnik

Student Theses

Media coverage of terrorist attacks plays an important role in shaping the public understanding of terrorism. While there have been several studies analyzing coverage of terrorist incidents prior to 9/11, there has been little research examining post-9/11 coverage. This study fills this gap by examining the media’s coverage of terrorism in the United States between the dates of September 12, 2001 and December 31, 2015. The analysis is based on a list of terrorist-related incidents and New York Times articles written on each incident. This study documents the amount of coverage received by these incidents and identifies the variables influencing …

Can Implicit Post-Event Information Influence Explicit Eyewitness Memory?, Hang Sze Chau

Student Theses

This study examines whether unconscious processing of misleading post-event information can influence explicit and implicit eyewitness memory. Using the existing misinformation paradigm, false post-event information was presented to participants either under full or divided attention. Eyewitness memory was tested with both explicit (free recall and cued recall tests) and implicit memory tests (truth rating test). Participants who were misinformed under full attention recalled significantly more misinformation than their counterparts who were misinformed under divided attention and the control group. However, results from the truth rating test showed that both explicit and implicit forms of misinformation had no impact on implicit …

Alcohol Use, Drinking Motivations, And Depression Among College Students: The Roles Of Sociotropy And Autonomy, Cameron P. Pugach

Student Theses

Sociotropy and autonomy are two cognitive personality dimensions, or personality styles, that have been implicated in the way individuals may uniquely develop, experience, and respond to treatment for depression. The goal of the current study was to investigate whether these cognitive personality dimensions are differentially related to drinking motivations and alcohol-related behaviors among college students. Participants included 311 college students (M_age = 23.1, 63% male) recruited via Amazon Mechanical Turk. Results partially supported hypothesized relationships showing that generally, those higher in sociotropy were more likely to endorse external motivations for drinking (i.e. social and conformity motives), while those …

Comparative Study Of Uniformed/Undercover Loss Prevention Agents In Reducing Shrinkage In Retail Businesses, Rustam Zakirov

Student Theses

This research examines the effectiveness of loss prevention strategies, specifically, uniformed and undercover Loss Prevention Agents (LPA), to determine the proper implementation of these strategies and provide necessary recommendations for the retail stores to lower the rate of shrinkage. It has been found that to date $13 billion worth of merchandise is stolen per year nationwide. Therefore, in order to reduce shoplifting, retail stores implement various loss prevention strategies among them: LPAs and others. Much research has been conducted in order to find an effective strategy for reducing shoplifting which among others impacts the rate of shrinkage. However, to date, …

Marital Rape Perception And Impact Of Force, Janelle N. Robinson

Student Theses

The majority of sexual abuse is committed by someone known to the victim. In fact, almost 75%-90% of rape victims know their perpetrator. While there has been a strong movement to identify and prosecute rape, one area that has still received relatively little attention in research and the media is marital rape. Research has found that marital rape is classified as less severe, less violating of women’s rights, and less psychologically damaging than rape taking place outside the marriage. To date, research has suggested that the perception of rape is influenced by a myriad of factors including the degree of …

Details In Testimony: How Hedge Words Influence People’S Perceptions Of Victim Testimony Credibility, Justine B. Rayborn

Student Theses

The purpose of this study was to examine whether hedge words and the age of a memory can influence the way participants (mock jurors) perceive an alleged sexual assault victim’s credibility. Prior research has demonstrated many issues that can affect the accuracy of memory for childhood events such as childhood amnesia, fragmented and distorted memories, false memories and source monitoring errors and the way in which jurors’ decisions can be swayed based on verbal cues to confidence. Here, we further investigated whether jurors' decisions are sensitive to the age of the memory—an event that happened in the recent or distant …

Psychopathy, Empathic Concern, And Emotional-Sentence Processing: An N400 Erp Study, Farren Larson

Student Theses

Using an undergraduate sample, the present study examined how psychopathic traits (assessed by the Psychopathic Personality Inventory-Revised) and empathic concern (assessed by the Interpersonal Reactivity Index) affect emotional-information processing using event-related potentials (ERPs) and a sentential priming paradigm. Participants had their electroencephalogram (EEG) recorded while they silently read sentences with three types of endings: congruent, incongruent, and emotionally negative. We hypothesized that participants with high levels of psychopathic traits and participants with low levels of empathic concern would find the emotionally negative sentence endings less unexpected and disturbing (yielding a smaller N400), compared to participants with low levels of psychopathic …

Treatment, Supervision, And Recidivism Of Individuals Convicted Of A Sex Offense In The United States: A Pilot Study, Gabriele F. Trupp

Student Theses

Although, previous research has shown that treatment programs for individuals convicted of a sex offense have the potential to lower sexual recidivism rates (Hanson & Bussiere, 1998; Hanson et al., 2002; Losel & Schmucker, 2005), there is some pause as to the methodological strength of these studies (Furby, Weinrott, & Blackshaw, 1989; Rice & Harris, 2003). Additionally, the literature is mixed regarding which elements of supervision for individuals convicted of a sex offense contribute to lower sexual recidivism (Aos, Miller, & Drake, 2006; Aytes, Olsen, Zakrajsek, Murry, & Ireson, 2001; Buttars, Huss, & Brack, 2016; McGrath, Cumming, Hoke, & Bonn-Miller, …

Detection Of Cathinone And Mephedrone In Plasma By Lc-Ms/Ms Using Standard Addition Quantification Technique, Theron W. Ng-A-Qui

Student Theses

Designer drugs are structural analogs of Drug Enforcement Agency (DEA) Schedule I and II substances. They are synthesized to mimic the effects of illegal drugs of abuse and to bypass the provisions of drug regulations. Despite the increased availability of designer drugs, few studies have focused on specific analytical extraction techniques for their detection and quantification in biological samples. Solid phase extraction (SPE) is the most commonly used technique for sample preparation. The purpose of this study is to evaluate the extraction efficiency of the various SPE columns with different sorbent materials for two designer drugs, cathinone and mephedrone in …

Inmate Death In Private And Public Prisons, Alexis Acevedo

Student Theses

Despite the vast body of research on privatization of prisons in the United States, little is known about the relationship between these types of facilities and death in custody. The literature on privatization compares private prisons to public prisons on many factors such as recidivism and cost-benefit analyses. However, there is a gap in the literature regarding death in custody in public and private facilities. This study focuses on both individual and facility level differences in Florida and Texas to explore potential difference in death in custody between public and private prisons. The research focuses on differences in the number …

Bayesian Approach To Toolmark Analysis, Antonio W. Del Valle

Student Theses

Statistical analysis of toolmarks using frequentist methods can be problematic for assorted reasons. Thus, in order to analyze toolmarks whilst avoiding these issues, a Bayesian approach is taken. Specifically for this thesis we discuss the computation of a specific Likelihood Ratio for toolmark comparisons. This Bayesian based approach involves using data already at hand in conjunction with a probability model in order to establish an estimate for its “value”, i.e. the “weight of evidence”. Making the calculations to obtain a Likelihood Ratio is very cumbersome and time consuming. Also many commercial software packages hide the process and underlying assumptions that …

Victim-Offender Relationships In Sexual Assault And Subsequent Disclosure And Reporting Styles, Amy R. Ramapuram

Student Theses

There is a discrepancy between the number of perpetrated sexual assaults and the number of reported sexual assaults. Past research has shown that one factor that could contribute to this discrepancy in reporting and disclosure of sexual assaults is the victim-offender relationship. Furthermore, there is evidence that victims of sexual assault minimize when describing their offense and their offender, which could further impact reporting and disclosure. The current study seeks to look into whether the victim-offender relationship influences the disclosure, reporting, and use of minimization, in reference to sexual assault. The victim-offender relationships that were analyzed were “stranger”, “friend/acquaintance”, “partner”, …

The Effect Of Phenotypic Bias On Lineup Construction Fairness, Sydney Y. Wood

Student Theses

There is converging evidence that people make inferences about others’ culpability and deservingness of punishment based on whether they express more of the African phenotype (e.g., darker skin, wider nose, thicker lips; Blair, Judd, & Chapleau, 2004; Eberhardt Goff, Purdie & Davies, 2004; Kahn & Davies, 2011). What is less clear is whether facial features that are phenotypically related to particular racial groups play a role in the mistaken identification of innocent Black suspects. Eyewitness descriptions lack detail with regard to racial phenotypes (Fahsing, Ask & Granhag, 2004; Nicholson & Kovera, 2013). Without descriptions containing phenotypic features to use when …

Attribution Of Blame In Rape: The Role Of Race, Alice Genna

Student Theses

Reports have shown that about 18 percent of women and 1 percent of men in the United States reported experiencing rape in the past (Center for Disease and Control Prevention, 2011). In addition, a previous study has shown that victims of rape are often reluctant to report the incidents, because they fear society’s perceptions of rape (Deming, Covan, Swan & Billings, 2013). Given this, it is important to study factors influencing individuals’ attribution of blame in rape. While many studies have focused on the role of gender, sexual orientation, and alcohol influence in perceptions of rape, research on the role …

Retrieval-Induced Forgetting Via Social Media: The Mnemonic Consequences Of Posting Pictures On Instagram, Chi Lap Wong

Student Theses

Social media has become a common tool for individuals to selectively offload personal memories to the internet. Such selectivity may reinforce the posted “memory” but induce forgetting for related “memories” (Anderson, Bjork, & Bjork, 1994). To explore this possibility, the present study adopted the retrieval-induced forgetting paradigm to the context of social media, Instagram. Participants were required to write a diary attached with pictures relevant to the events and then post pictures to the Instagram, followed by the final recall test. The results indicated that posting personal pictures online induced forgetting in related memories but not pictures, and posting …

An Exploration Of Youth Experiences In Chatrooms, Emily A. Greene-Colozzi

Student Theses

Internet predation of minors has increasingly become a focus of child abuse research and legislation. Concerns have arisen regarding “online grooming,” the ongoing process during which an adult offender prepares a child for sexual abuse by gaining emotional access to the child through an intimate online relationship. The present study provided one of the first comprehensive examinations of a victim's perspective of online grooming. Participants were 374 male and female college students at a public undergraduate institution who completed an online survey covering demographics, lifestyle factors, and experiences online of sexual solicitation or online grooming. Results showed that approximately 30% …

Chemical Identification Of Synthetic Cannabinoids In Herbal Incense Products, Karol F. Alvarez Heredia

Student Theses

The emergence of synthetic cannabinoids is an ongoing challenge for forensic, clinical analytical chemists and toxicologists. Different analogs are continuously introduced in the market to circumvent the legislation and to enhance their pharmacological activity. In the present project, a total of seven synthetic cannabinoids were identified in four herbal incense products by employing GCMS, and LC-TOF. Fractional collection of four out of the seven synthetic cannabinoids was performed using HPLC followed by the collection of FTIR-ATR spectra. Five out of seven synthetic cannabinoids were classified as indazole carboxamide derivatives, which include 5Fluoro-EMB-Pinaca, 5Fluoro-AMB, MA-Chminaca, AB-Chminaca, and 5Fluoro-AKB-48. The remaining two …
