Variants Of Social Disorganization: A Comparison Of Community Characteristic Measures On Crime Between Urban And Rural Counties In The United States, Shun Q. Feng

Student Theses

Abstract

Statement of Problem: This research examines the difference in the predictive nature of conventional social disorganization measures on seven (7) different crime types between urban and rural counties in the United States during 2014. There is a well-developed body of criminological research examining the effect of neighborhood disadvantage on crime through the social disorganization framework. However, social disorganization has been tested almost exclusively in urban or metropolitan areas, suggesting the current framework explaining criminal incidents through conventional measures of neighborhood disadvantage may be limited by “urban bias”. The present study seeks to test the conventional measures of social disorganization …

Effect Of Age And Sex On The Discrimination Of Monozygotic Twins Using Cg18562578 Dna Methylation In Saliva, Carla Pierre Louis

Student Theses

DNA methylation is a type of epigenetic modification that impacts gene expression without disturbing the genetic nucleotide sequence. DNA methylation has the potential to be included in the daily forensic analysis because among other uses, it has the potential to be applied to discrimination of monozygotic (MZ) twins that currently cannot be differentiated via forensic DNA profiling. In previous research, our group showed that DNA methylation at the cg18562578 site in chromosome 3 could be used to discriminate MZ twins. Because studies have shown that DNA methylation measures can be influenced by demographic factors such as sex and age; here, …

Exploring The Relationship Between Anger, Aggression, And Perpetrator Substance Use In The Commission Of Sexual Offenses, Dominique Rivera

Student Theses

This study examined the potential association between perpetrator substance use, anger, and aggressive behavior in the commission of sexual crimes. The sample included 246 adult males convicted of rape (n = 54) or child molestation (n = 192). Descriptive statistics revealed that 64.6% of the individuals in this sample (n = 159) were intoxicated at the time of the offense. Results showed that perpetrators who used substances at the time of the offense were more likely to exhibit aggressive behavior toward the victim (e.g., weapon use, verbal abuse) than those who did not. Offenders with higher pervasive anger scores were …

Estimating Muzzle To Target Distance From The Physical Characteristics Of A Bullet Hole In Different Wood Substrates, Alan Lee

Student Theses

Determining the muzzle to target distance of a firearm discharge is an integral part in crime scene reconstruction. Shooter distance is most often estimated using the Modified Griess test, which can be used to visualize gunshot residue (GSR) patterns around bullet holes. However, this test has a 3- to 5-feet range limit as the plume of GSR particles can only travel a certain distance past the muzzle. The purpose in this study was to develop a new method that overcomes this range limitation by analyzing the physical damage characteristics of a bullet hole. Test fires were conducted with a .22 …

The Determination Of G1 And G7 Ballistic Coefficients Of .22lr Caliber Ammunition In Gypsum Board Through Doppler Radar Acquisition, Jose A. Colon Jr.

Student Theses

In this experiment, a method of calculating ballistic coefficients of .22LR (long rifle) caliber ammunition was developed using Doppler radar to track the pre-impact and post-impact velocities of projectiles passing through gypsum board. The method demonstrated has distinct advantages in accuracy and flexibility over conventional chronograph projectile tracking that forensic firearm experts should consider when determining the optimal method to obtain a ballistic coefficient (BC). G1 and G7 ballistic coefficients were determined for three .22LR ammunition brands with respective muzzle velocities of approximately 1050ft/s (320m/s), 1230ft/s (375m/s), and 1640ft/s (500m/s) fired from a Ruger 10/22 semi-automatic carbine using an Infinition …

An Evolution Of Legal Rights For Guantanamo Bay Detainees: Habeas Corpus In The 21st Century, Jennifer Hirst

Student Theses

Guantanamo Bay, resting under United States’ jurisdiction since the early 20th century, has infamously stood as the symbol for where alleged terrorists and constitutional protections disappear. However, between the years of 2004 – 2008, the United States Supreme Court ruled on four landmark cases, gradually providing Guantanamo Bay detainees constitutional protections and access to the writ of habeas corpus – allowing detainees for the first time to challenge the legalities behind their detentions. Subsequently, judicial and executive powers have continuously contested one another, as Supreme Court rulings and documents released by the Bush Administration have intentionally aimed to minimize the …

Impacts Of Mental Health First Aid On Mental Health Literacy And Stigma, Junseon Hwang

Student Theses

Mental Health First Aid has been developed to train the general public to give initial support to those in mental health crisis and development. The effectiveness of Mental Health First Aid has been questioned due to its relatively short history of the course. Mental Health First Aid was recently widely-disseminated in New York City as part of the ThriveNYC initiative. While most studies were supportive of the training, there has been no study that specifically examines New York residents. We recruited 328 New York residents who self-reported whether or not they have participated in Mental Health First Aid via Amazon …

Effects Of Microwave Radiation On The Digestion Of Proteins Involved In Body Fluid Identification, Aaron J. Fox

Student Theses

Body fluid identification plays an important role in understanding how the events during a crime may have taken place. The presence of a body fluid may help identify an individual who committed a crime, while the type of body fluid present may help investigators determine how a crime occurred. Current body fluid identification techniques are not always conclusive and may only suggest the presence of a body fluid type. A protocol developed by the New York City Office of the Chief Medical Examiner (OCME) established a method that confirms body fluid type through mass spectrometry. To identify marker proteins in …

Performance Of A Dna And Protein Co-Extraction With Trypsin In Comparison To Two Proteinase K Based Dna Extraction Methods, Dinura A. Gunatilake

Student Theses

Effective DNA extraction methods are important for forensic applications. The main goal of this experiment was to determine if a newly developed trypsin based protein/DNA co-extraction method applied to contact traces would yield comparable results to a commercial Proteinase K method (QIAamp DNA Investigator Kit) and a Chelex extraction method with Tween 20 used in forensic laboratories. This was tested on 20 sets of sebaceous fingerprints on glass slides.

The results of this study demonstrate the trypsin co-extraction method yielded the highest amount of DNA. In the first comparison, the mean total DNA yields for the trypsin-co extraction method and …

The Mnemonic Consequences Of Posting “Self” And “Other” Photos On Social Media, Chloe L. Cardinale

Student Theses

The use of the internet and social media is ubiquitous. Research has shown that 90% of young Americans are active social media users, as well as 35% of American adults over the age of 65 (Perrin, 2015). When individuals use social media, they may selectively remember the information they post while simultaneously forgetting the information they did not post, but is related to the posted information (Anderson et al., 1994). The present study is an adaption of Anderson and colleagues’ retrieval-induced forgetting paradigm (RIF), consisting of personal and non-personal information. This study will specifically focus on the relationship between posting …

The Relationship Between Impact Energy And Glass Fracture Via .177 Caliber Steel Bbs, Jocenel Beach

Student Theses

Fractured glass is often found at shooting scenes and can provide useful information for crime scene reconstruction. Mechanical glass fracture from a projectile impact can result in different types of fracture patterns. The degree of fracture depends on several factors including: type of glass, the thickness of the glass, curvature (if any), distance from the muzzle, contact angle, and type of projectile. Correlating impact energy to the degree of glass fracture can provide useful information regarding the muzzle-to-target distance for a particular firearm/ammunition combination. This research focuses on the projectile impact velocity of .177 steel BBs shot from a pneumatic …

Further Evaluation Of A Dry Vacuuming Technique For Recovery Of Dna From Handwritten Documents, Christian Hopkins

Student Theses

A previously developed, non-destructive, homemade vacuum method for collecting biological material from handwritten documents had promising DNA results for white copy paper, preserved indented writing, and latent prints. Prior to casework implementation, additional validation experiments are warranted and here the method was tested for different paper substrates. This work describes testing of notebook paper, bank deposit slips, magazine pages, and manila envelopes. The quantity of recovered DNA varied from donor to donor, but the mean quantities showed a trend that can be explained by the different sizes and surface properties of the tested paper types. The rougher paper type, like …

Method Development For Identifying Counterfeit Cigarettes Using Environmental Pollen Analysis, Tiffany Chan

Student Theses

Cigarette counterfeiting negatively impacts government revenue and undermines tobacco control policies. Tracking geographical origins and potential trade routes of counterfeit cigarettes is important for investigation illegal trade in tobacco products. Traditional pollen extraction techniques provide clear residues of pollen trapped on tobacco leaves and used for geographical identification; however, such methods are time-consuming and utilize concentrated chemicals. This study developed a simple, fast and environmentally friendly method for extraction of pollen grains used in differentiating genuine and counterfeit cigarettes. Experimental factors that may affect pollen recovery including number of cigarettes, extraction solution, and extraction temperature, were optimized. The optimum parameters …

Developing A Maceration Method For Isolation Of Dna From Cancellous Bones, Bryan Bernal

Student Theses

Prior to isolating DNA, it is necessary to remove any biological materials that may be present on commingled remains. Manual maceration of the outer surface is time-consuming. This study will address this issue by developing a simple method for processing bone samples prior to DNA isolation. A liquid-based technique was applied to macerate bone fragments by incubating bone fragments in an enzyme solution, removing potential contaminants, followed by a bone tissue disruption. Swine (Sus scrofa) bones were used to simulate human bones. Microscopic analysis suggested this method was effective for surface material removal. The methods effect on the …

The Application Of A Simple Tissue-Disruption Method To Dna Extraction For Species Identification, Jordana R. Fox

Student Theses

The TissueLyser II was used to disrupt animal bones and plant tissue without dry ice or liquid nitrogen for species identification. Bone fragments of fresh swine (Sus scrofa) ribs were used. A 521bp fragment of the cyt b locus was analyzed, and the BLASTn results confirmed that the origin of all the samples was swine (E-value = 0.0). Bone fragments of bovine, chicken, duck, fish, sheep, and swine were also used to test the procedure. An approximately 600bp fragment of the COI locus was analyzed, and the BLASTn results confirmed the origin of all the samples (E-value = …

Archaeology Or Crime Scene? Teeth Micro And Macro Structure Analysis As Dating Variable, Jessica A. Vincenty

Student Theses

Simple methods to aid in the determination of forensic or archaeologic relevancy of skeletonized remains have been researched since the 1950s. With advances in microscopic imaging techniques and machine learning computer data analysis methods the relevancy of decontextualized, comingled remains has room for improvement. This thesis is a study done to pioneer a new approach to analyzing dental skeletal remains to determine forensic relevancy.

Archaeological dental samples collected from the ancient city of Ur in modern day southern Iraq in addition to modern dental extractions were processed for scanning electron microscopy imaging. Archaeological and modern samples displayed different surface and …

Hostile Attributions To Ambiguous Situations: A Vignette Study Of The Mediating Role Of Hostile Attributions In The Relationship Between Community Violence Exposure And Youths’ Aggressive Behaviors, Hyun Kim

Student Theses

The effect of exposure to community violence has received increasing attention in recent years, given its prevalence and negative psychological and behavioral consequences on adolescents, including aggression (Lambert et al., 2018). The existing literature links violence exposure to hostile interpretation of situations (Dodge et al., 1990; Huesmann, 1988), and hostile interpretations to aggressive responses (Bradshaw et al., 2009; Crick & Dodge, 1994; Dodge et al., 1990). However, most studies have focused on parenting practices and within home violence. Few studies have examined the possible mediating role of hostile attribution bias in the relationship between community violence exposure and youth aggression, …

Juveniles Tried As Adults:The Impact Of Youth Demographic Factors On Juror Perceptions, Denieka Ellis

Student Theses

Abstract: This study explored the impact of defendant age, race and stereotypic crime on verdicts and recommended sentencing of juveniles tried as adults. Previous research shows that jurors enter trial with negative preconceptions and biases of juveniles because they are being tried within an adult venue. These negative preconceptions have led jurors to recommend harsher sentencing for juveniles rather than adults with the same defendant characteristics and criminal history. Crime type and crime severity have also been shown to impact perceptions of juvenile defendants in adult court. However, research has not yet explored the potential impact that stereotypic crime—a crime …

Examining Afro-Cultural Values In African American Women With Childhood Sexual Abuse History: Its Relationship With Therapeutic Outcomes, Bibi Aneesa Subhan

Student Theses

In the United States, African American women are not only more likely to have experiences of childhood sexual abuse (CSA) but experience some of the severest forms of it. The presence of Afro-cultural values can play a significant role in the therapeutic outcomes of women who do seek out treatment after their experiences of CSA. That is, Afro-cultural values such as spirituality, communalism, utilization of the Black Church, and adherence to the Strong Black Women archetype (SBWA) can impact the efficacy of treatment for Black female survivors of CSA. The purpose of this study is to assess the separate relationships …

An Examination Of Defense Attorney Knowledge Of Dispatcher Practices In Eyewitness Calls, Elena Christofi

Student Theses

911 dispatchers are often the first point of contact for witnesses to crimes. Dispatchers have an important role in collecting information related to a witness’ observations and recollection of events, and this information can serve as primary evidence in criminal cases. Therefore, it is crucial that evidence collected from eyewitnesses is as accurate and detailed as possible. In the present study, we investigated defense attorneys’ perceptions on how dispatchers gather information from eyewitnesses during 911 calls, because little is known with respect to how defense attorneys review, use, and challenge 911 calls. Using an online survey, we asked defense attorneys …

An Analysis Of The Parental Structure And Involvement On Subsequent Delinquency, Bosco Villavicencio Jr

Student Theses

This thesis examines how parental involvement and family structure relate to the prevalence of juvenile delinquency. To answer the research question, the current study used a large sample of 12^th grade youth (n=1,272) from the Monitoring the Future project which includes measures on parental involvement, household structure, academic abilities, and risky behavior and delinquent behavior. The results of this secondary analysis showed a significant association between parental-child involvement measures and the delinquent outcomes examined; drinking, suspension, and skipping school. This study emphasizes the need to consider that the impact of household structure as well as that of a supportive …

Evidence Based Practices At A New York City Youth Justice Services Organization, Betsy Delissa Cespedes

Student Theses

There has been a national push to establish evidence-based juvenile criminal justice policies and practices that are focused on reducing the risk of recidivism for juvenile offenses. The reason for this push is rooted in the growing recidivism rates of juvenile offenders in the United States (Weber, Umpierre, & Bikchik, 2018). More than half of all juveniles who are on probation nationwide are rearrested, indicating that each juvenile offender faces equal likelihood of reoffending or not (Weber et al., 2018). Further, approximately 66% of juvenile offenders, or nearly seven out of 10 offenders, are rearrested within two years of their …

Felony Disenfranchisement: Factors Relating To Support For Restoration, Alexis K. Karpf

Student Theses

Felony Disenfranchisement, a collateral consequence, strips justice-involved individuals of their voting rights. While this policy is enacted in 48 states and the District of Columbia, a majority of community members are unaware of its existence. The current study used three hypotheses to guide its research about how education about disenfranchisement policy impacts a community member's opinion:1) Participants exposed to information about the effects of disenfranchisement will be more supportive of enfranchisement than those in the control condition; 2) Participants who receive the vignette featuring the White justice-involved individual will indicate a higher level of support for enfranchisement compared to those …

Semi-Quantitative Detection Of Signature Peptides In Body Fluids By Liquid Chromatography Tandem Mass Spectrometry (Lc-Ms/Ms), Tebah N. Browne

Student Theses

This study covers a modified semi-quantitative approach for liquid chromatography mass spectrometry (LC-MS/MS) signature peptide detection for body fluid identification. Peptide concentrations were measured based on synthetic peptide standards. Samples were processed with varying trypsin digestion and purification protocols, including a three-hour trypsin digestion and Microcon membrane filtration. The Microcon filtration method generates polymerase chain reaction (PCR) compatible DNA and peptide fractions that can be analyzed without any further purification. Preliminary validation tests covered stains on different substrates, semen/ saliva mixtures, minimum sample volume, and repeatability. All signature peptides in the multiplex were present at different concentrations and varied amongst …

Impact Of Think/No-Think Paradigm On Memory For Inadmissible Evidence, Catherine Hackett

Student Theses

Jurors are typically not able to disregard inadmissible evidence when asked to do so by judges. Yet, there is no research using the think/no-think paradigm on juror memory, which could be beneficial for trials in which inadmissible evidence is an issue. This study uses witness photos and statements to see if the material can be intentionally remembered and intentionally forgotten through a think/no-think task in which participants are cued to think about some witness photo/statement combinations and not think about other photo/statement combinations. Participants were responsible for learning pairs of faces and statements of witnesses from an alleged stabbing. After …

Dementia And Competency In United States Courtrooms: A Case Law Review, Dana Miller

Student Theses

The number of older adults in the United States is rising, as is the incidence of dementia. Older adults are coming into contact with the criminal justice system at greater rates than previously encountered. As such, individuals with dementia are likely appearing in courts at an unprecedented rate. While many civil competencies commonly related to older adults are well researched, competency in the criminal legal system has not received the same level of recognition in this population. This is particularly concerning given the growing awareness of the relevance of dementia in some criminal competencies (e.g., Madison v. Alabama, 2019). Of …

The Criminalized Victim: Can Knowledge Of Trauma And Coercion Influence Free Will Doubt And Perception Of Culpability For Sex Trafficked Individuals?, Megan Korovich

Student Theses

Individuals who have been sex trafficked are continuously being targeted for prostitution and other related offenses instead of being recognized for their victimization. This may occur due to a fundamental lack of understanding of the sex-trafficked experience, allowing for misperceptions to form unhindered. Individuals with these misperceptions then go on to form laws and services intended to aid victims, but instead leave them vulnerable and criminalized. This study assessed whether an educational intervention on the experience of a sex-trafficked individual could influence public perceptions of free will doubt and criminal culpability. This study used a nonequivalent groups posttest-only design to …

The Romanticization Of Violent Male Offenders: How Trauma And Internalized Sexism Can Explain Women's Fascination With Serial Killers, Ella R. Johnson

Student Theses

Past research has noted that women are interested in true crime more than men (Vicary & Fraley, 2014), and that some women romanticize violent male offenders (Isenberg, 1991). This study investigated women’s fascination with serial killers compared to other offenders and the psychological correlates of women who are fascinated with serial killers. I hypothesized women’s fascination was unique to serial killers and may be related to safe and culturally acceptable ways of coping with interpersonal trauma. Results largely support these hypotheses, indicating women were more fascinated with serial killers compared to other offenders, and with PTSD, child abuse, intimacy attitudes, …

Psychopathy And Police Officers: A Cross-Sectional Analysis Of The Relationship Between Psychopathic Traits And Police Work Across Temporal Factors, Hunter N. Moore

Student Theses

It’s estimated that psychopathic personalities constitute about 1% of the general population but is seen at elevated rates in particularly stressful and harsh environments (Babiak & Hare, 2006; Hare, 1996). A career in law enforcement is one known to be uniquely stressful (Lucas et al., 2012), and the trauma from their career seems to be having an impact on their personality (Wills & Schuldberg, 2016). While psychopathy traits have been reported in police officers (Próchniak, 2012), these traits have yet to be assessed as a function of time. The current study explores these relationships by assessing psychopathy traits, as measured …

Remembering School Shootings: An Examination Of Intergenerational Differences, Kelly Huie

Student Theses

In recent years, school shootings have evolved from rare occurrences to a full-blown epidemic, causing generations of students to have a realistic fear of attending school. When negative or traumatic events like a school shooting occur, people often form long lasting recollections of where they were, when learning about the traumatic, public event. Hence, the aim of this study was to understand if certain school shootings are more memorable for Americans, and whether differences exist across generations, as certain school shootings that occur during the reminiscence bump period (i.e., between the ages 10 – 30) may influence which shooting is …
