Evaluating De-Escalation Training At The National And Regional Levels: A Mixed Methods Analysis Of Officer Perceptions And Use Of Force, Samantha A. Tosto

Doctoral Works at the University of New Haven

High profile incidents of police misconduct and excessive use of force, particularly in cases of racialized violence against unarmed Black men, have led to a sociopolitical reckoning with the American criminal justice system. Following several of these incidents in the past decade, scholars, policymakers, and the public all have called for significant reform and the prioritization of de-escalation skills for law enforcement officers during citizen interactions. Despite these efforts, little empirical evidence has been established regarding the effectiveness and generalizability of de-escalation training programs. The current research represents a mixed-methods evaluation of the National De-escalation Training Center’s program at both …

A Comprehensive Examination Of The Post-Conviction Risk Assessment (Pcra) And Risk Prediction Index (Rpi) For General Risk Factors, Criminogenic Outcomes, And Risk-Specific Populations, Logan J. Distasio

Master's Theses

The use of risk assessment instruments has become an increasingly pertinent issue in the realm of reentry. Though sometimes controversial, risk assessment tools provide local, state, and federal governments with actuarial techniques focused on providing unbiased and accurate risk assessments for individuals returning to the community. The present study was focused on the further evaluation of two risk assessment instruments utilized by the Administrative Office of the United States Courts (AOUSC)—the Post-Conviction Risk Assessment (PCRA) and the Risk Prediction Index (RPI). A mixed-methods approach was taken in order to investigate the associations between these tools, general risk factors, criminogenic outcomes, …

Recovery Of Nuclear Dna From Skeletal Remains Decomposed In Freshwater, Zoe L. Sikon

Master's Theses

This research compared freshwater and dry decomposition environments and their impact on DNA recovery from Sus scrofa domesticus(domestic pig) femora over a 3-month period. Prior to decomposition, initial cuttings were taken from "fresh" bone samples. Cuttings were then collected at 3-week intervals from waterlogged and dry bone samples. All samples were extracted using the vendor recommended protocol for the Applied Biosystems PrepFiler BTA extraction kit and an updated version of the same protocol, that substitutes Proteinase K with additional Dithiothreitol (DTT) (Thermo Fisher Scientific, 2012.). DNA quantitation was performed using pig-specific custom primer sets, with the QuantStudio 5 Real-Time …

The Application Of Particle-Correlated Raman Spectroscopic Analysis Of Soils To Mock Casework Scenarios, Sam Gong

Master's Theses

Soil is a continuous material, reaching across geological bodies, and is distinctly variable and differentiable based on aspects such as geographic location, seasonal factors, and human interference. In combination with its highly transferable nature, the complexity of soil makes it valuable material for forensic trace evidence and object-to-scene association. The development of forensic soil analysis is currently focused on mineralogy. Raman spectroscopy is a chemical technique that has previously been studied for mineralogy uses. Additionally, Raman spectroscopy has been researched for use in other fields of forensic science as well. As such, it is possible to use Raman spectroscopy for …

Effects Of Ethanol On Gaba Transaminase, Mary Corrigan

Master's Theses

Ethanol is the primary active ingredient in alcoholic beverages, and functions in the body as a central nervous system (CNS) depressant. The overt effects ethanol has on the body, e.g. diminished cognitive ability, loss of motor control, slurred speech, impaired balance, etc., are well documented. While the behavioral consequences of consumption are well understood, how ethanol actually functions on a mechanistic level to elicit those effects has yet to be satisfactorily elucidated.

The structural homology between ethanol and the C3 and C4 carbons of gamma-hydroxybutyric acid (GABA), the major inhibitory neurotransmitter in the mature CNS, has led us to hypothesize …

The Detection Of Blood And The Recovery Of Dna From Heat-Damaged Surfaces, Teresa A. Distefano

Master's Theses

When investigating a scene exposed to high temperatures and long burn times, investigators should consider that recoverable blood could be linked to a source and give important profile information after DNA analysis. By locating blood with presumptive and confirmatory reagents, even after exposure to damaging conditions, investigators can attempt not only to confirm that blood was present but also to determine the DNA profile of the blood. Experimenting with the different burn times and temperatures in which blood is still detectable can be followed with DNA analysis, which will show whether the blood is viable after exposure to these damaging …

An Evaluation Of The Effect Of Degradation On Irisplex Snps, Maria Gruber

Master's Theses

The information from short tandem repeats (STRs), the current standard forensic DNA typing technology, does not always result in identification. In these cases, there are other informative markers in DNA that can be used to help generate investigative leads, one of which is single nucleotide polymorphisms (SNPs). One of the uses of SNPs is for phenotype determination. Among the phenotypic characteristics that can be predicted is eye color. A commonly used tool for eye color prediction is the free, online statistical prediction model IrisPlex, which includes 6 SNPs known to control eye color.

While SNPs can be useful, they, like …

Trace Dna Detection Using Diamond Dye: A Recovery Technique To Yield More Dna, Leah Davis

Master's Theses

This study aspires to find a new screening approach to trace DNA recovery techniques to yield a higher quantity of trace DNA from larger items of evidence. It takes the path of visualizing trace DNA on items of evidence with potential DNA so analysts can swab a more localized area rather than attempting to recover trace DNA through the general swabbing technique currently used for trace DNA recovery. The first and second parts consisted of observing trace DNA interaction with Diamond Dye on porous and non-porous surfaces.

The third part involved applying the Diamond Dye solution by spraying it onto …

Rattus Norvegicus As A Biological Detector Of Clandestine Remains And The Use Of Ultrasonic Vocalizations As A Locating Mechanism, Gabrielle M. Johnston

Master's Theses

In investigations, locating missing persons and clandestine remains are imperative. One way that first responder and police agencies can search for the remains is by using cadaver dogs as biological detectors. Cadaver dogs are typically used due to their olfactory sensitivity and ability to detect low concentrations of volatile organic compounds produced by biological remains. Cadaver dogs are typically chosen for their stamina, agility, and olfactory sensitivity. However, what is not taken into account often is the size of the animal and the expense of maintaining and training the animal. Cadaver dogs are typically large breeds that cannot fit in …

The Impact Of Bone Marrow Transplantation On Forensic Human Identification And Genetic Genealogy Testing, Lisa A. Sikop

Master's Theses

Forensic Investigative Genetic Genealogy has rapidly evolved to become a highly effective investigative tool to assist with identifying perpetrators of violent crimes and unidentified human remains. With forensic DNA (STR) analysis, it has previously been researched that a person who has received a bone marrow transplant (BMT) may produce a multi-allelic STR profile, as both the bone marrow donor and the recipients' DNA is present. A multi-allelic STR profile can easily be misinterpreted as a mixture DNA profile, when in fact it is a chimeric DNA profile originating from a single individual. While the impact of chimerism on STR profiles …

Evaluation Of Raman Microspectroscopy And Hyperspectral Imaging As A Screening Tool To Determine Optimal Sampling Sites For Dna Recovery From Human Skeletal Remains, Kathleen M. Smith

Master's Theses

Numerous challenges exist with forensic genetic testing of human skeletal remains due to diagenesis patterns in bone microstructure, DNA degradation, and the presence of PCR inhibitors. Diagenesis is the microscopic breakdown of the bone matrix, which consists primarily of mineralized calcium hydroxyapatite and collagen. The process of diagenesis occurs in a heterogeneous, non-uniform manner along the diaphysis of a long bone, and determining the region with the most intact bone microstructure is not possible with the naked eye. Therefore, taking cuttings from the diaphysis for DNA testing is somewhat of a “blind” process, and decades of research and casework have …

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 …

The Rise Of Terrorism In Africa And What It Means For U.S. Policymakers, Bridget Mary Hughes

Master's Theses

This thesis utilizes three case studies to measure the rise of terrorism in Africa. This qualitative data leads the reader to one ultimate question: what does the rise in terrorism in Africa mean for the United States (U.S.) and U.S. policymakers, National Security academia, students in National Security, if anything at all? The answer is: if civilian and military compounds are being targeted by these violent extremists, as these three case studies demonstrate, it is my recommendation that U.S. policymakers cease sending troops to the African theater and, instead, allocate funding to the citizens and nonprofits of the countries whom …

Quantifying Pain: A Ratio Of Cortisol, Substance P, And Pituitary Adenylate Cyclase-Activating Polypeptide As Biomarkers For Pain In Animal Cruelty And Neglect, Danielle Sherer

Master's Theses

Understanding the relationship between cortisol, Substance P, and PACAP during experienced pain and recovery, as well as the contrast between expression levels and serum levels, will provide an objective measure of pain and suffering to aid in the prosecution of animal cruelty and neglect cases.

There is no consensus at this time as to a recognized biomarker for pain experienced by an animal. Cortisol, Substance P, and Pituitary Adenylate Cyclase-Activating Peptide (PACAP) have been investigated separately in various animal and human studies with regard to stress, pain, and injury. Cortisol is a steroid hormone in the glucocorticoid class that has …

Evaluating The Panoptic Deterrent Effect Of Skywatch Surveillance Towers: A Mixed Methods Analysis, Penny M. Geyer

Doctoral Works at the University of New Haven

The internalization of an all-seeing gaze is an important component of crime control, whether in the form of suitable guardians, place managers, or meticulous surveillance ceremonies. Specifically, panoptic technologies have the potential to “normalize” behaviors through visible yet unverifiable surveillance. Although marketed as a technology that deters crime, SkyWatch surveillance towers’ actual deterrent effect has never been empirically evaluated. Such an assessment is critical not only from a crime reduction perspective, but also one of cost-effectiveness as these towers cost hundreds of thousands of dollars.

Utilizing a sequential triangulation mixed method procedure, information from 21 semi-structured interviews was combined with …

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 …

Cheating From A Distance: An Examination Of Academic Dishonesty Among University Students, Timothy K. Daty

Doctoral Works at the University of New Haven

Academic dishonesty among college students has been an enduring issue within higher education. While prior research has explored this issue, the recent global pandemic has shifted collegiate demographics dramatically, particularly within online courses. As a result, previous findings may prove less applicable, warranting new research into student cheating within this current educational landscape. Given these new enrollment trends, this study investigated intentions to cheat in traditional and online class settings, and for criminal justice and non-criminal justice majors. Utilizing principles of rational choice theory, other factors related to academic misconduct also were explored.

For this study, original data were collected …

The Effects Of Family Structure Stability And Parenting Practices On Juvenile Delinquency: Variations By Immigrant Generational Status And Race/Ethnicity, Lanmeng Ma

Doctoral Works at the University of New Haven

While the important role of various psychosocial factors in the development of criminality has long been acknowledged, many researchers, criminologists and criminal justice professionals firmly believe that family is specifically at the core. The purpose of this dissertation is to examine the relationships among family structure stability, parenting practice dimensions, and concurrent/subsequent delinquent behaviors, both theoretically and empirically. This study investigates how immigrant generational status and racial/ethnic disparities modulate associations between the stability of family structure, aspects of parenting practices, and adolescent delinquency, using a nationally representative sample from the National Longitudinal Study of Adolescent to Adult Health (Add Health). …

Forensic Artifact Finder (Forensicaf): An Approach & Tool For Leveraging Crowd-Sourced Curated Forensic Artifacts, Tyler Balon, Krikor Herlopian, Ibrahim Baggili, Cinthya Grajeda-Mendez

Electrical & Computer Engineering and Computer Science Faculty Publications

Current methods for artifact analysis and understanding depend on investigator expertise. Experienced and technically savvy examiners spend a lot of time reverse engineering applications while attempting to find crumbs they leave behind on systems. This takes away valuable time from the investigative process, and slows down forensic examination. Furthermore, when specific artifact knowledge is gained, it stays within the respective forensic units. To combat these challenges, we present ForensicAF, an approach for leveraging curated, crowd-sourced artifacts from the Artifact Genome Project (AGP). The approach has the overarching goal of uncovering forensically relevant artifacts from storage media. We explain our approach …

The device identifiers presented in this work may also be used to definitively detect device usage. Likewise, the DHCP logs …

Another Brick In The Wall: An Exploratory Analysis Of Digital Forensics Programs In The United States, Syria Mccullough, Stella Abudu, Ebere Onwubuariri, Ibrahim Baggili

Electrical & Computer Engineering and Computer Science Faculty Publications

We present a comprehensive review of digital forensics programs offered by universities across the United States (U.S.). While numerous studies on digital forensics standards and curriculum exist, few, if any, have examined digital forensics courses offered across the nation. Since digital forensics courses vary from university to university, online course catalogs for academic institutions were evaluated to curate a dataset. Universities were selected based on online searches, similar to those that would be made by prospective students. Ninety-seven (n = 97) degree programs in the U.S. were evaluated. Overall, results showed that advanced technical courses are missing from curricula. We …

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 …
