Multiple Perpetrator Sexual Assault: The Relationship Between The Number Of Perpetrators, Blame Attribution, And Victim Resistance, Yi Jin Genevieve Lim

Student Theses

Sexual assault has been and continues to be a prevalent public health and social problem that can lead to severe ramifications for the victim. There has been growing research on multiple perpetrator sexual assault (MPSA) and how it qualitatively differs from single assailant offenses. However, there is a paucity of studies investigating the differences between sexual assault perpetrated by duos versus three or more individuals and how it affects victim behavioral responses and blame attribution. This study aimed to examine the relationship between the perceived level of victim blame and the number of perpetrators in MPSA cases contingent on the …

911 Dispatchers: Their Role As Evidence Collectors, Brittany P. Kassis

Student Theses

911 dispatchers are often the first point of contact after an individual is in an accident, needs emergency assistance, or witnesses a crime. In an emergency involving a crime, a dispatcher can play an important role in assisting the investigative process and collecting evidence, such as an eyewitness’ description of the suspect. While trained in how to gather situational and locational information from a caller so that relevant first responders can be notified, dispatchers may not be trained on how the specific language they use with a caller can impact the caller’s memory for the event. Thus, if dispatchers are …

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 …

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 …

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 …

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. …

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 …

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, …

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 …

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 …

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 …

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 …

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”, …

Effects Of Defendant Group Status And Inclusion Of A Lesser Charge On Participant-Juror Verdict Preferences, Brittany Decesare

Student Theses

Black, Hispanic and White participant-jurors read a murder trial transcript in which the defendant belonged to either one of the other racial/ethnic groups (outgroup) or their own racial/ethnic group (ingroup). In the two-verdict condition, participants were provided with two verdict options: guilty or not guilty. In the three-verdict condition, participant-jurors were provided with three verdict options: guilty of second-degree murder (primary charge), guilty of voluntary manslaughter (lesser charge) or not guilty. In all conditions, participants provided their verdict preference, verdict certainty, the defendant’s likelihood of guilt and the strength of evidence. Participants in the two-verdict condition indicated higher proportions of …

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 …

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% …

Does Distance Equal Length? : The Effect Of Relational Closeness On Length Of Sentencing In Child Sexual Abuse, Brittney Peiffer

Student Theses

Expectations of how family and friends are supposed to treat children may influence decision- making in child sexual abuse cases. These expectations can be understood from a moral code and moral violation perspective, such that broken moral codes formed by society can elicit negative emotions resulting in moral hypervigilance. Moral hypervigilance is the need to mediate the negative emotions elicited by the moral code violations with action, such as deciding the length of sentencing for a person who the moral code. This study examined the impact of relational closeness and victim gender on the length of sentencing for child sexual …
