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 …

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 = …

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 Effects Of Podcasts On Mental Health Stigma, Sarah N. Dure

Student Theses

Research indicates that media can have both negative and positive impacts on mental health stigma and self-stigma. No studies, to our knowledge, have examined the impact of audio media representation (podcasts) on mental health stigma. Our study therefore examines the effects that both positive and negative portrayals of mental illness in a news podcast would have on mental health stigma. We hypothesized that participants assigned to podcast conditions that primed for mental illness would lead participants to attribute an incident to mental illness. Additionally, we hypothesized that listening to a podcast that speaks negatively about individuals with mental illnesses would …

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 …

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 …

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 …

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 …

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 …

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 …

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 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 …

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 …

Exploring Vicarious Trauma In The Archives: A Brief Survey Of American Archival Experiences, Victoria A. Fernandez

Student Theses

Whether deliberately collected or not, evidence of trauma is commonly found in archival collections. As a result, the field has seen a recent increase in conference presentations regarding archivists’ experience of working with traumatic materials, yet little has actually been researched or published. Vicarious trauma, as it is known in psychological contexts, is the understanding that individuals engaging with survivors of trauma may experience the emotional labor of their clients in secondary form. Although the concept of vicarious trauma is almost exclusively applied to mental health professionals, archivists are recognizing the need to integrate the prevalence of vicarious trauma within …

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 …
