A Fusion Of Microscopy Technique In Human Coprolite Analysis: The Dyck Cliff Dwelling And The Arid West Cave, William Darwin Hertzel

Anthropology Department: Theses

In the two papers that comprise this thesis, I will discuss the dietary complexes of two separate Southwestern archaeological sites excavated in the 20th century through the medium of coprolite analysis. The fusion of microscopy techniques in this project expands the capability of observation and identification of microremains and their use in reconstructing the dietary habits of past peoples. I intend to highlight the value of integrating three separate methods of microscopy for the identification of diet and any practices for using that information to narrow down a coprologically unstudied site location for samples of lost provenience. Additionally, this project …

Firearms And Toolmark Error Rates, Susan Vanderplas, Kori Khan, Heike Hofmann, Alicia L. Carriquiry

Department of Statistics: Faculty Publications

We have outlined several problems with the state of error rate studies on firearm and toolmark examination. Fundamentally, we do not know what the error rate is for these types of comparisons. This is a failure of the scientific study of toolmarks, rather than the examiners themselves, but until this is corrected with multiple studies that meet the criteria described in Section 3, we cannot support the use of this evidence in criminal proceedings.

A Review Of The Mandible, Emily Hill

Anthropology Department Scholars Week

A Review of The Mandible by Emily Hill

The mandible is one of the 22 bones in the human skull. This paper aims to encapsulate the basic features of the human mandible while also addressing the evolution and morphological mandibular variation between mammals. It also aims to address the role that anthropology and all its sub-disciplines has played in the exploitation and erasure of Indigenous peoples. There must be a significant push to decolonize the field of osteology. The mandible is useful for forensic applications such as post-mortem identification. In a rapidly expanding technological world, new ways of studying the …

An Empirical Analysis Of Individual Events In Collegiate Forensics, Jordan Duffin Wong

Honors Theses

Anecdotally, it is a widely accepted notion in the United States’ collegiate competitive speech and debate community that a competitor’s strong record of competitive performance in the activity at the high school level is a powerful predictor of similar success in the activity at the collegiate level. However, no evidence has been brought to bear supporting this claim. This paper uses the universe of American Forensic Association National Individual Events Tournament results from 2013 to 2018 and links collegiate competitors to their respective high school performance data. I demonstrate evidence that high school experience does, in fact, appear to play …

We also developed and implemented a tool that aided in the timely

acquisition and identification of artifacts from the examined applications.

Additionally, our work explored the type of …

Fighting The Formula: Adherence To Unspoken Rules Limit The Value Of Individual Events, Eric Mishne

Communication Faculty Publications

Forensics is one of the most valuable activities in which college students can be involved. However, the strict adherence to formula and unspoken rules diminishes the educational benefits. This article explores an extensive body of literature highlighting the concerns of formulaic practices in collegiate forensics. The author asserts that authenticity, genuine learning, transferability of skills, innovation, and high quality speaking are the biggest victims of stringent adherence to the forensic formula. Specific recommendations for competitors, judges, coaches, and organizing bodies are given, suggesting that there are alternatives which can mitigate growing concerns.

What Can Anthropologists Do?: Applied Anthropology In A Conflict-Ridden World, Emma G. Dorshimer

Student Publications

This work examines the role of anthropology in conflict, post-conflict studies, and conflict resolution. Present research has asserted that Anthropology as a discipline must move forward with greater involvement in domestic and international conflict resolution, but no scholar nor activist has taken that leap. All anthropological research in conflict has pertained to forensic anthropology, expert witness testimony, and post-conflict ethnographic research— all completed after conflict has already ended. Many anthropologists have recommended involvement in actual conflict resolution, and many have advocated for further Ethnographic Peace Research. However, the role of anthropology continues to be questioned by the discipline itself as …

Optical Tweezers As An Effective Tool For Spermatozoa Isolation From Mixed Forensic Samples, Nicole Auka, Michael Valle, Bobby D. Cox, Peter D. Wilkerson, Tracey Dawson Cruz, Joseph E. Reiner, Sarah J. Seashols-Williams

Forensic Science Publications

A single focus optical tweezer is formed when a laser beam is launched through a high numerical aperture immersion objective. This objective focuses the beam down to a diffraction-limited spot, which creates an optical trap where cells suspended in aqueous solutions can be held fixed. Spermatozoa, an often probative cell type in forensic investigations, can be captured inside this optical trap and dragged one by one across millimeter-length distances in order to create a cluster of cells which can be subsequently drawn up into a capillary for collection. Sperm cells are then ejected onto a sterile cover slip, counted, and …

Our work presents the primary account for exploring the forensics of immersive Virtual Reality (VR) systems and their social applications. The Social VR applications studied in this work include Bigscreen, Altspace VR, Rec Room and Facebook Spaces. We explored the two most widely adopted consumer VR systems: the HTC Vive and the Oculus Rift. Our tests examined the efficacy of reconstructing evidence from network traffic as well as the systems themselves. The results showed that a significant amount of forensically relevant data such as user names, user profile pictures, events, and system details may be recovered. We anticipate that this …

Experience Constructing The Artifact Genome Project (Agp): Managing The Domain's Knowledge One Artifact At A Time, Cinthya Grajeda, Laura Sanchez, Ibrahim Baggili, Devon R. Clark, Frank Breitinger

Electrical & Computer Engineering and Computer Science Faculty Publications

While various tools have been created to assist the digital forensics community with acquiring, processing, and organizing evidence and indicating the existence of artifacts, very few attempts have been made to establish a centralized system for archiving artifacts. The Artifact Genome Project (AGP) has aimed to create the largest vetted and freely available digital forensics repository for Curated Forensic Artifacts (CuFAs). This paper details the experience of building, implementing, and maintaining such a system by sharing design decisions, lessons learned, and future work. We also discuss the impact of AGP in both the professional and academic realms of digital forensics. …

Breaking Into The Vault: Privacy, Security And Forensic Analysis Of Android Vault Applications, Xiaolu Zhang, Ibrahim Baggili, Frank Breitinger

Electrical & Computer Engineering and Computer Science Faculty Publications

In this work we share the first account for the forensic analysis, security and privacy of Android vault applications. Vaults are designed to be privacy enhancing as they allow users to hide personal data but may also be misused to hide incriminating files. Our work has already helped law enforcement in the state of Connecticut to reconstruct 66 incriminating images and 18 videos in a single criminal case. We present case studies and results from analyzing 18 Android vault applications (accounting for nearly 220 million downloads from the Google Play store) by reverse engineering them and examining the forensic artifacts …

A Descriptive Analysis Of Porcupine Scavenging In An Experimental Forensic Context, Tamara Marie Labanowski

Honors College

Addressing the impact of scavengers is essential for a complete analysis of many forensic sites. Despite considerable research on canids and rodents on a broad taphonomic scale (Haglund 1992; Haglund et al. 1989; Haynes 1983), the North American porcupine (Erethizon dorsatum) has not been studied for its impact in forensic contexts. In order to address this research gap, I will explore the role of the porcupine in scavenging bone based on data collected during a recent experimental taphonomic study (Sorg 2013). Funded by the National Institute of Justice, this study included data from motion- and heat-sensitive cameras focused on domesticated …

Memes: The Interaction Between Imagery And Subculture: An Analysis Of Situation, Race, And Gender On The Pi Kappa Delta Social Media App, Veronica Scott, Timothy Bill

Oswald Research and Creativity Competition

Collegiate speech and debate participants are committed to performance excellence and organizational unity. Pi Kappa Delta, a central organization for this subculture, annually hosts a national competition, during which competitors can create and post memes via the tournament phone app. While it is well-known that memes are a function of participatory culture, no analysis has yet examined memes exclusively consumed by the same subculture which created them. In this study, we examine the implicit messaging of this memetic imagery, and by doing so, gain insight into both the collegiate forensics subculture, and the function of memes in a small group.

The Optimization Of Pressure Cycling Technology (Pct) For Differential Extraction Of Sexual Assault Casework, Vanessa Martinez

FIU Electronic Theses and Dissertations

A two-step protocol has been devised as a rapid and selective alternative to conventional differential extraction techniques with an increased recovery of DNA. The protocol involves pressure cycling with the Barocycler^® NEP 2320 from Pressure Biosciences. Inc. in alkaline conditions for epithelial cell lysis and removal. This step is followed by alkaline lysis at 95^º C for extraction of sperm cell DNA. At 1:1 or 2:1 female to male cell ratios, high selectivity and complete separation can be achieved. But at higher ratios, male allelic dropout is observed. This protocol has been modified to generate a clean male …

E-Cigarettes May Be A Clue At Crime Scenes, Jessica Mayfield

Fors 401: Forensic Biochemistry—A Peer Review Of Teaching Project Inquiry Portfolio, Ashley Hall

UNL Faculty Course Portfolios

Students who participate in active and experiential learning activities develop a better understanding of basic scientific principles and are also more likely to be retained in a STEM discipline. Developing such activities, however, can be difficult. In the present study, we sought to develop classroom activities to engage university students and increase understanding of the theory and practice of forensic science. One common accessory amongst the target audience was the ever-present media, both social and popular (entertainment). In fact, a majority of students report watching at least one of the many popular forensic science shows on TV. Therefore, we hypothesized …

Psychology Faculty Scholarship

The field of psychology and law, including forensic psychology, is an exciting concentration of research activity and student training and has grown rapidly, but to what extent have teaching and training efforts in the field been systematically catalogued and evaluated? We conducted a historical review and content analysis of the American and Canadian literature on the scholarship of teaching and training in the field. This review catalogs (a) information related to the development of training and teaching, (b) descriptions of programs and courses at various levels, and (c) articles on teaching resources or techniques in this field. We hope it …

Identification Of Characteristic Volatile Organic Compounds Released During The Decomposition Process Of Human Remains And Analogues, Norma Iris Caraballo

FIU Electronic Theses and Dissertations

The manner in which remains decompose has been and is currently being researched around the world, yet little is still known about the generated scent of death. In fact, it was not until the Casey Anthony trial that research on the odor released from decomposing remains, and the compounds that it is comprised of, was brought to light. The Anthony trial marked the first admission of human decomposition odor as forensic evidence into the court of law; however, it was not “ready for prime time” as the scientific research on the scent of death is still in its infancy.

A Change In Competition: Assessing The Nfa-Ld Community And Its Views On Topical Counterplans, Matthew Whitman

Mahurin Honors College Capstone Experience/Thesis Projects

Intercollegiate academic debate allows students to participate in various contests and competitions to demonstrate expertise in argumentation and public speaking (Freeley & Steinberg 2009). The National Forensic Association's Lincoln-Douglas (NFA-LD) debate is a two-person style of policy-based debate, and it borrows much of its argumentative structure from other team-based debate organizations (Freeley & Steinberg, 2009). Yet it also prohibits other theoretical arguments from being used through its codified rules. This project seeks to examine current NFA-LD community attitudes towards the prohibition of topical counterplans, a theoretical negative argument, in the event.
