Advancing Forensic Firearm Analysis: Quantitative Measurement Of Pellet Patterns Using Open Source Software, Inez Staples

Master of Science in Forensic Science Directed Research Projects

Shotgun pellet pattern analysis plays a critical role in forensic firearm investigations, particularly for estimating muzzle-to-target distances. However, conventional methods based on pattern diameter become unreliable when only partial patterns are recovered, as is often the case in forensic scenarios involving soft tissue or incomplete impact surfaces. This study aimed to validate ImageJ, an open-source image analysis software, as a standardized, accurate, and reproducible tool for measuring pellet-to-pellet distances in partial shotgun patterns. The methodology included calibration of ImageJ using a perforated poly board, comparison of manual versus digital measurements on 17 pre-made pellet patterns, and development of a calibration …

Impact Of Substrates And Deposition Time On Bacteria Associated With Saliva Samples And Its Implication On A Bacterial Signature-Based Body Fluid Identification Method, Olisdey Galano Cruz

Master of Science in Forensic Science Directed Research Projects

Traditional serological methods for body fluid detection are limited by poor specificity and sensitivity, lacking confirmatory capability and thereby increasing the risk of false positives that may compromise the integrity of forensic investigations. While molecular methods such as mRNA, miRNA, and DNA methylation offer improved specificity, they are often hindered by marker instability and operational complexity in routine forensic workflows. Bacterial signature profiling has emerged as a promising alternative, offering enhanced stability, abundance, and compatibility with existing DNA workflows. However, its forensic implementation requires further validation. This study evaluated the effects of substrate type and storage time on the salivary …

Guardians Of Their Own: Routine Activities, Risk Perceptions, & Self-Protection Among Police Officers In The Line Of Duty, Amy Clifton-Mills

Theses and Dissertations

This research illuminated how police officers perceive risks in the line of duty and whether police officers implement protective behaviors on duty. This was done by implementing two phases of data collection: focus groups (I) and self-report surveys (II). The focus groups (N = 21) were conducted to inform the self-protective behaviors instrument in the self-report surveys (N =143). Officers self-reported their risk of assault and injury in the line of duty in the next six months to be 33.86% (SD = 27.13) and their risk of felonious death to be 14.4% (SD = 18.1). Results show that …

Nature, Nurture, And Serial Murder: A Biocriminological Analysis Of Jeffrey Dahmer And Aileen Wuornos, Dori W. Jal

Honors Thesis

In recent years, there has been an increase in public fascination with serial killers, however current criminological explanations continue to focus on social and psychological factors, lacking commentary on potential biological implications. This thesis addresses a gap in the literature by examining how biological processes, specifically epigenetic, neurobiological, and endocrinological mechanisms, interact with environmental stressors to shape serial homicidal behavior. The goal is to determine whether serial murder can be more effectively understood through a biosocial framework that integrates biological vulnerability with lived experience, rather than relying on singular explanatory models.

Using a qualitative multiple-case study methodology, this research analyzes …

Center on Children, Families, and the Law: Faculty Publications

Background: Engaging families effectively in child welfare services remains a persistent challenge, shaped by complex interactions between agency practices and family circumstances. While existing research has explored this issue, it has predominantly relied on data from agency and caseworker perspectives, often overlooking the crucial viewpoint of the families. Objectives: This study investigates families’ subjective experiences and perceptions within the child welfare system, focusing on their satisfaction with child welfare workers and overall engagement. Methods: The study draws on data collected through an evaluation of the implementation of Alternative Response in a Midwestern state. Agency administrative data is integrated with additional …

Reevaluating Felon-In-Possession Laws After Bruen And The War On Drugs, Laura Ginsberg Abelson

Faculty Journal Articles and Book Chapters

The legal landscape surrounding firearm possession is evolving rapidly. In 2022, the Supreme Court accelerated its expansion of the individual right to bear arms under the Second Amendment in New York Rifle & Pistol Ass’n v. Bruen. Since Bruen, courts around the country have struck down nearly all types of firearm regulations, with a notable exception: felon-in-possession laws. This Article examines the implications of a legal landscape where those who have prior felony convictions, and especially prior drug convictions, are punished harshly for the same behavior—possession of a firearm—that is constitutionally protected for nearly everyone else. I argue …

A Study Of Pattern Of Cybercrime Abuse Of Individual Internet Users In Umuahia North Lga, Abia State Of South-Eastern Nigeria, Ogochukwu Favour Nzeakor, Rita Ngozi Okafor, Chibuike Ndubuisi Nwoke

International Journal of Cybersecurity Intelligence & Cybercrime

Although a number of studies exist on cybercrime and its abuses, little is known about the pattern of cybercrime abuses individual Internet users experience in Nigeria, especially the south eastern region. Using data collected via various methods, this study examines the pattern of cybercrime abuses of individual Internet users in Umuahia, Abia State, of South Eastern Nigeria. The result of the analysis of 1,067 samples drawn from 223,134 Internet users in Umuahia North LGA of Abia Sate showed that: while most users are victims of stolen ICT-gadgets (19%), fraud related offences (17%), and hacking (15%); they rarely fall victims of …

The Rights Of Nature Meaning-Making Experiments In Ecuador: A Pragmatist Inquiry, Lourdes Aguas Gonzalez

Electronic Theses & Dissertations (2024 - present)

Ecuador is the first and only country in the world to recognize nature as a subject of rights in its national Constitution, with the most court cases to date, and with a vibrant moral imagination regarding the more-than-human world. Building on the pragmatist tradition, my research examines three questions: What are the rights of nature in Ecuador? How is nature politically represented in Ecuadorian legal forums? And how can collective problem-solving experiments around the rights of nature in Ecuador inform moral inquiry? To answer these questions, I bring sociology in conversation with philosophy. My theoretical and methodological tools as a …

Welfare States And Imprisonment Rates: Revisiting The Study Of Public Assistance And Punishment In The United States, Stefan Ivanov

Electronic Theses & Dissertations (2024 - present)

In the past fifty years, the United States has seen significant changes in both the criminal legal system and the welfare state. The incarceration rate surged by 475% from 1972 to 2007, driven by state-level decisions about criminal legal policy and disproportionately affecting Black Americans. Simultaneously, welfare programs became less generous, especially for those deemed “undeserving.” A long line of social science scholarship emphasizes that these two major social institutions—the welfare state and the carceral state—must be considered as complementary and alternative methods of managing marginalized groups. Quantitative research often confirms these claims, finding a durable inverse relationship between welfare …

Complex Lives And Procedural Barriers: Detainees’ “Life Happens” Explanations For Breaching Orders, Natalie Gately, Suzanne Rock, James L. Finney, Cate Parry

Research outputs 2022 to 2026

The Australian bail system routinely permits most individuals accused of a crime to remain in the community while awaiting a court date under a range of conditions. However, statistics have indicated that a high number of bailees breach the orders placed on them, increasing police and court interactions, and resulting in additional charges. This project utilised the Drug Use Monitoring in Australia – Western Australia (DUMA-WA) collection to survey 230 police detainees about their orders and reasons for breaching recent orders. The results indicated that most understood their orders but disclosed a range of complexities which interfered with compliance. Qualitative …

Why Domestic Violence Offenders Don't Give Up Their Guns, Natalie Nanasi

Faculty Journal Articles and Book Chapters

Perpetrators of intimate partner violence are barred by federal law and many states' laws from possessing firearms. While such prohibitions enjoy popular support, they are sporadically and inconsistently enforced, placing the lives of survivors at risk when offenders do not voluntarily comply. Many experts, including this author, have offered legal and policy solutions to increase the likelihood that perpetrators of domestic violence will either willingly relinquish their guns or otherwise be dispossessed of them. But these proposals may have been premature.

This Article is the first to take a step back and inquire why offenders do not surrender their firearms …

Analyzing Car Theft Trends In Central Texas: A Comparative Study Of Waco, College Station, And Killeen, Daniel Njogu

Williams Honors College, Honors Research Projects

This study examines motor vehicle theft (MVT) trends from 2019 to 2023 in three Central Texas cities—Waco, College Station, and Killeen—using temporal analysis, geospatial hotspot mapping, and make/model data. In Killeen, thefts generally rose over the period, with notable peaks in October and on Mondays. College Station saw an overall decline in thefts but experienced a seasonal spike each March, and Waco’s thefts increased until around 2021 before beginning to fall. Local festivals—such as the Spirit of Texas in College Station and the Heart O’ Texas Fair in Waco—appear to coincide with these seasonal upticks. Hyundais and Kias were most …

Breaking A Criminal Mind: Leveraging Habit Breaking/Building For Crime Reduction, Dru Gerace

Williams Honors College, Honors Research Projects

Criminal behavior is often shaped by a complex interaction between psychological processes, habitual actions, and neurobiological mechanisms. This research explores how habitual decision-making and reinforcement patterns contribute to criminal tendencies, integrating insights from neuroscience and psychology. The study examines how early-life experiences, cognitive biases, and environmental factors shape habitual behaviors that may predispose individuals to criminal activity. It also discusses the role of executive functioning, impulse control, and neuroplasticity in breaking maladaptive patterns. By analyzing contemporary theories of habit formation and their neurological underpinnings, this paper offers a multidimensional perspective on the development of criminal behavior. Furthermore, implications for rehabilitation …

A New Deepfake Detection Method With No-Reference Image Quality Assessment To Resist Image Degradation, Jiajun Jiang, Wen-Chao Yang, Chung-Hao Chen, Timothy Young

Electrical & Computer Engineering Faculty Publications

Deepfake technology, which utilizes advanced AI models such as Generative Adversarial Networks (GANs), has led to the proliferation of highly convincing manipulated media, posing significant challenges for detection. Existing detection methods often struggle with the low-quality or compressed press, which is prevalent on social media platforms. This paper proposes a novel Deepfake detection framework that leverages No-Reference Image Quality Assessment (NRIQA) techniques, specifically, BRISQUE, NIQE, and PIQUE, to extract quality-related features from facial images. These features are then classified using a Support Vector Machine (SVM) with various kernel functions. We evaluate our method under both intra-dataset and cross-dataset settings. For …

Perceptions And Treatment Decisions For A Drug Offender Based On Social Class, Cocaine Type, Personal Characteristics, And Compassionate Love: A Vignette Study, Yasmin A. Odeh

Theses and Dissertations

Problem: The shift from a focus on rehabilitation to the more punitive, “tough on crime” approach to illegal behavior in the U.S. has been enacted in no small way by policies connected to the use and abuse of drugs. The disparities between crack and powder cocaine—two chemically similar substances—have headlined this shift (Vagins and McCurdy 2006). However, research is scarce on laypeople’s approval of deterrence approaches for drug offenses, including as a function of types (e.g., powder vs. cocaine possession). This study examined people’s perceptions of prosecutorial decisions for drug offenders—whether they are punished, rehabilitated, or both—and whether people perceived …
