The Impact Of The Covid-19 Pandemic On Risk Factors For Fatal Intimate Partner Violence And Domestic Violence Services Provided, Faith E. Alves

Honors Theses

The current study assessed the COVID-19 pandemic-related changes in risk factors for fatal intimate partner violence (IPV) among female victims. It additionally analyzed IPV services received before and during the pandemic. Data came from a system that most domestic violence (DV) agencies in Connecticut utilize to record their contacts with their clients, including an initial screening through a police-social service intervention. Results indicated that unemployment of the partner was significantly higher in the during-COVID group. Additionally, the delivery of criminal justice services was significantly higher in the pre-COVID group whereas delivery of law enforcement services was significantly higher in the …

Evaluation Of Raman Spectroscopy As A Screening Tool To Predict Dna Recovery Potential In Skeletonized Human Remains, Cody Silverman

Honors Theses

The purpose of this study is to determine if Raman spectroscopy can be used as a rapid and non-destructive screening tool to predict DNA recovery potential for bone, and to explore the correlation between the compositional microstructure of bone and preservation of DNA. The two primary structural components of bone are calcium hydroxyapatite and collagen. It is proposed that by analyzing bone using Raman spectroscopy, the presence, state, and distribution of hydroxyapatite and collagen can be measured, which may be useful in predicting if the sample is viable for DNA analysis. The ultimate goal of this study is to develop …

An Investigation Of The Effect Of Temperature And Humidity On The Formation Of Antemortem Root Banding, Mae Griffin

Honors Theses

Microscopical hair analysis has become a controversial practice within forensic science primarily due to issues related to interpretation, and specifically overstating the significance of an association. The validity of microscopical hair comparisons has suffered from intense scrutiny by the forensic community, with one criticism being a paucity of peer reviewed research. An often-unrecognized aspect of microscopical hair analysis is its use in providing reconstructive information based on identifiable features. One example of this is postmortem root band or PMRB. PMRB is the formation of a band slightly above the root bulb and below the skin surface on the hair of …

A Social Learning Perspective On Sexual Coercion, Mallory Ferrick

Honors Theses

Akers’ (2009) social learning theory proposes that individuals learn deviant behavior through the same learning processes by which they learn conventional behavior. Social learning theory has been applied as an explanation for an array of deviant behaviors; however, no known published research has explored the theory’s ability to explain the perpetration of sexual coercion. This project investigated the extent to which Akers’ social learning theory can be applied to sexual coercion. This project utilized a sample of undergraduate students enrolled in various courses at a private four-year institution in the northeast. Descriptive statistics revealed a lack of variability among responses …

An Interdisciplinary Analysis Of Dehumanization During The Holocaust, Alissa Marie Davies

Honors Theses

The body of literature surrounding the Holocaust and dehumanization is extensive. Multiple theories have been proffered to try and explain the Holocaust’s causation, each with varying degrees of acceptance from the Jewish and global communities. Meanwhile dehumanization has been studied however often through the lens of a singular field. Despite the abundance of research on the Holocaust, the subject of perpetrators has had limited exploration as of yet. The present analysis seeks to examine the mechanics of dehumanization and how these mechanics could explain the behaviors behind the perpetration of the Holocaust and by extension, other genocides. This analysis will …

No One Is Above The Law: Public Perception Of Prosecutorial Misconduct's Influence On Wrongful Convictions, Amanda N. Pappas

Honors Theses

Wrongful convictions pose a large threat to the integrity of the United States criminal justice system. While there are many known causes of wrongful convictions, such as eyewitness misidentification, ineffective counsel, and false confessions, the most egregious cause is prosecutorial misconduct. According to the National Registry of Exonerations, prosecutorial misconduct has been found in roughly half of the exonerations listed in the registry. Prosecutors have a tremendous amount of power in the criminal justice system through determining plea deals, obtainment of evidence, disclosure of evidence to the defense, and many more. Studies have been conducted that reveal the occurrence of …

Amino Acid Composition Analysis As A Means To Differentiate Hair Samples From Individuals Of Similar Demographics And The Effect Of Hair Treatments, Trisha Brady

Honors Theses

Hair is a forensically-relevant exhibit due to its ability to be shed, torn, or transferred during a crime. Current forensic hair analysis includes microscopic hair comparison and mitochondrial or nuclear DNA analyses, each with limitations. Novel methods, such as those evaluated herein, have potential to complement conventional techniques. These include evaluating functional groups with infrared (IR) spectroscopy, elements with laser induced breakdown spectroscopy (LIBS), and amino acid ratios with gas chromatography- mass spectrometry (GC-MS). Hair from two demographically similar individuals was divided into three sample groups per individual: untreated, bleached, and dyed. Spectral differences between individuals and treatments were evaluated …

Evaluation Of The Effect Of The Humic Acid Inhibitor On Forensic Genetic Investigations Of Human Skeletal Remains, Madeline King

Honors Theses

Postmortem survival of DNA in human skeletal remains occurs due to the compact microstructure of the skeleton and its ability to provide a strong, protective physical barrier to environmental insults. On a molecular level, DNA preservation in bones/teeth involves electrostatic interactions between the negatively-charged DNA backbone and positively charged calcium residues in hydroxyapatite, the latter of which is one of the main components of bone microstructure. Despite these protections, over time endogenous DNA becomes damaged, limiting our ability to detect it and affecting its utility in making a positive identification. Hence, forensic genetic investigations of unidentified human remains (UHRs) are …

Race And Social Class As Factors Associated With Sentence Disparities: A Survey Of Potential Jurors, Amanda Rickett

Honors Theses

Prior research has found that bias, along with other extralegal factors, leads to the sentencing disparities in the criminal justice system throughout the United States. The criminal justice system has implemented reforms to address these disparities. Furthering research on this issue, I analyze previous studies that tried to determine the effects of bias on the decisions made by judges and juries. Most importantly, the present study aimed to determine the effects of race and socioeconomic class of the defendant on the decisions on potential jurors using a vignette based survey with randomized assignment. The results suggest that the potential jurors’ …

Extraction Of Human Dna From Soil In A Simulated Clandestine Grave, Arely Joaly Parra Lopez

Honors Theses

Locard’s Exchange Principle states that “every contact leaves a trace.” The same principle applies when a perpetrator of a homicide decides to bury a victim in a clandestine grave. If a perpetrator originally buried a murder victim in haste to prevent discovery and then decided to later move the victim’s body to a remote location for disposal, decomposition fluids from the victim’s body (which contain cellular material and therefore DNA) would remain in the surrounding grave soil at the original burial site. It is possible that investigators could: 1) prove that a human body had once laid in that location …

Investigating The Use Of Saligae® To Identify Expirated Blood On Various Material, Maria Bigos

Honors Theses

Expirated bloodstains and impact bloodstains have very similar physical characteristics. The main way Blood Pattern Analysts identify bloodstains in based on their physical characteristics. This can lead to difficulty distinguishing between expirated blood and impact spatter. Expirated blood can be identified through the presence of air bubbles, however these are often only present on non-porous surfaces. However, if expirated bloodstains can be identified through the presence of saliva, this can provide an alternative way to identify expirated bloodstains. This study examined if SALIgAE can be accurately used to identify the presence of saliva in blood and thus, be a way …

Investigation Of Palatal Rugoscopy For Forensic Human Identification, Cameron Filipe

Honors Theses

Human identification is critical to the field of forensic science as well as in many sub-disciplines, including forensic pathology, forensic anthropology, and forensic odontology. While few widely-accepted methods of identification dominate the discipline (primarily fingerprint and dental record analysis), the study of palatal rugae patterns (rugoscopy) is an emerging tool in human identification. Some studies suggest that patterns of the palatal rugae are an individualizing characteristic among humans. While the use of rugoscopy for identification has been explored as an identifying marker in the dental and orthodontic communities, its use for forensic applications is not widely recognized. Also, while some …

Impact Of Denial Of Sexual Offenses On Sentencing And Treatment Strategies, Jenna Luallen

Honors Theses

The prevalence of sexual offenses calls for a reevaluation of how the system treats offenders and addresses indicators of risk. How an individual convicted of a sexual offense accepts or denies the assault can weigh heavily on the sanctions imposed upon them, and how the system processes the offender. Acceptance of guilt is an important goal in offender treatment programs, and denial is reportedly used as an indicator of high risk of recidivism. Deeper examination into how individuals who deny their offense are understood and processed throughout treatment aids in the identification of best practices for working with sex offender …

Delinquency In The Caribbean: Stakeholder Perceptions Of Root Causes, Laura Nolterieke

Honors Theses

There is a gap in the research on juvenile delinquency within the Caribbean context. As countries such as St. Lucia, Guyana, St. Kitts, and Nevis have growing delinquency and crime rates, there is a need to bridge this gap in the literature. This research sought to examine the main causes of juvenile delinquency within St. Lucia, Guyana, St. Kitts, and Nevis, as described by juvenile justice stakeholders, such as probation officers, prosecutors, and judges, within their respective countries. Through the use of grounded theory, the data were coded and analyzed using a constant comparison method. From these data, six themes …

Investigating The Efficacy Of Dna Damage With Bleach In Forensic Laboratories And At Crime Scenes, Alyssa Tuccinardi

Honors Theses

Household/commercial bleach (6% NaOCl, sodium hypochlorite) degrades DNA through oxidative damage, production of chlorinated base products, and cleavage of DNA strands (breaking it into smaller and smaller fragments). The presence of these lesions significantly impacts the ability to generate a full genetic profile from an evidentiary sample. In fact, knowledge of the damaging effect of bleach on DNA is the basis for its use in forensic laboratories to clean workbenches and prevent cross-contamination of samples between cases. Additionally, bleach is used intentionally by criminals to clean up crime scenes and destroy DNA evidence. A previous study demonstrated that bleach has …

Photofading Of Black Dyes In Cotton And Polyester Fibers Resulting From Environmental Exposure To Sunlight, Maggie E. Mahaney

Honors Theses

Color is one of the most important properties analyzed during forensic fiber examinations due to its discriminatory power. Differing colors in fibers are usually sufficient grounds for exclusion, but in cases where a lengthy period has passed between crime commission and evidence recovery, the high probability of environmental degradation having altered the questioned fibers’ properties could lead to false exclusions. Photofading, the loss of color resulting from exposure to light, is a common form of degradation observed in fibers. Although well-known in the dyeing industry, it is not typically factored into forensic fiber examinations. Published photofading research has been limited …

Small Island Taphonomy In Western Australia, Courtney J. Newberry

Honors Theses

Forensic death investigations rely on postmortem interval estimations to establish a timeline surrounding a decedent’s death. Several methods are used, often together, to make such estimations. One of the main methods is the evaluation of the stage of decomposition; although decomposition follows the same general steps, the length of the process can vary by location and environmental factors. Animal scavenging can also impact decomposition by consuming flesh and impacting insect activity on the remains.

This study investigates the scavenging guilds and rate of decomposition of pig (Sus scrofa) legs on Rottnest Island, Australia. Three sites with unique environments were selected …

How Gun Control Laws Affect Homicide, Abbey Maloney

Honors Theses

Homicide is an ever-prevalent problem in the United States (U.S.). One solution that is often turned to is the implementation of stricter gun control laws. This causes much divide as many citizens are not in agreement about whether or not these laws do what they are intended to. The aim of this study was to determine whether or not gun control laws have an effect on homicide, and, if so, what this effect is. The U.S. states were evaluated in several different categories to determine how strict or lax their gun laws were. They were scored using the number of …

Effect Of 17a - Ethynylestradiol On The Pupation Rate, Emergence Rate, And Sex Ratio Of Phormia Regina (Calliphoridae), Bethany K. Hoschar

Honors Theses

After death, blowflies are attracted to decomposing remains for feeding and reproduction purposes. Since blowflies are usually the first species to colonize a set of remains, they are important to forensic scientists when estimating the time since death. Using the knowledge of the life cycle of a blowfly and any interferences of the environment that can affect the development, forensic entomologists can estimate the time since the arrival of blowflies, otherwise considered time since deposition. This research investigated how a specific estrogen, 17 a-ethynylestradiol, present in pollutants affects the development time of blowflies, and therefore the time since death estimation. …

Impact Of High Profile Police Use Of Force Incidents On Violent Crime Rates, Megan Galante

Honors Theses

This research study examined the relationship between high-profile police use of force incidents and local violent crime rates. It is important to analyze the impact that police use of force has on the respective community in regard to crime rates. This study analyzed three incidents of police use of force that have received extensive coverage in the media in order to determine if there was a change in the rates of violent crime in that city. The theory of de-policing suggests that in the aftermath of a high-profile incident of police brutality, police departments in the area change their behaviors …

Evaluation Of Dna From Blood And Saliva Overtime, Janine Smalling

Honors Theses

In this research, we will examine the quantity of DNA over time. In John M. Butlers, "Fundamentals of Forensic DNA Typing", he charts out the average amount of DNA extracted from different bodily fluid samples. Examples include blood, semen, saliva, urine, etc. Though valuable, the values presented are in the cases of a fresh extraction of the sample. It is important to note that in most cases when DNA is being extracted from crime scene evidence, the samples are not fresh and have been degraded to some extent. On a crime scene, time is only one of the factors affecting …
