Coomassie Brilliant Blue Dye As A Method For Analyzing Fracture Markings In Bone, Abigail Hoffmeister, David Harutunyan, Matthew Aizawa, Everett Baker, Brandon Mendoza, Chase Freeman, Siran Iskanian

Seaver College Research And Scholarly Achievement Symposium

Coomassie Brilliant Blue Dye is a dye commonly used to stain proteins. Because of its ability to adhere to proteins, this research has focused on perfecting a method of dyeing a fractured flat bone in order to most accurately observe and analyze fracture markings within the trabecular layer. Stereoscopic microscopy was the chosen technique of analysis for this research because of its proven effectiveness in glass and ceramic fractography to observe varying depths. In order to most effectively apply stereoscopic microscopy to this research, the following variables were manipulated to maximize color contrast in the trabecular layer in order to …

Mentorship As An Evolving Practice: Emma And Justin's Excellent Adventure, Justin G. Foote, Emma Murdock

Speaker & Gavel

This paper provides a semi-autoethnographic exploration of the evolving practice of mentorship within forensic debate. Ultimately, this paper is situated within previous literature, such as Buell's (2004) understanding of mentorship models, but expands on the need for an evolving mentorship model within student-professor mentorship, especially as the student role changes from undergraduate student to graduate student. The researchers' arguments in this paper are around how mentorship in student-professor relationships needs to adapt as the student's role changes from novice to experienced competitor and eventually from student to coach. The goal of the mentor-mentee relationship is long-term success for both parties …

Avian Scavenging In The Forensic Context, Austin Millwood

Senior Theses

Many cultures have recognized the importance of birds in scavenging. However, within forensic literature and research, avian scavenging is an understudied phenomenon. Despite this, researchers have shown that scavenging by birds is unique from other types of scavenging in that birds can rapidly cause complete skeletonization, leave relatively little bone damage, and can spread remains and artifacts over a large area. Here birds known to scavenge are explained in a biological context and then their effects on remains are analyzed. Birds are capable of completely scavenging human remains in as little as 5 hours, depending on many understudied factors. Avian …

Extraction Of Challenging Forensic Samples Using The Microgem Dna Extraction Kit, Falyn R. Vega

Student Theses

In forensic science, DNA extraction can be a tedious and resource-intensive process. Extraction with Proteinase K is an industry standard but has its drawbacks, such as requiring multiple ionic detergents and washing steps. MicroGEM has developed a new enzyme called forensicGEM that is temperature-dependent and compatible with mesophilic enzymes, offering complete DNA extraction in about 20 minutes in a single tube, limiting contamination, loss of sample, and working time. ForensicGEM can extract DNA from highly degraded samples, potentially leading to more complete STR profiles. Highly degraded tissue and bone samples were collected and extracted with the forensicGEM …

The Relationship Between Schizophrenia Spectrum Disorder And Criminal Responsibility, Taylor A. Chille

Psychology Doctoral Specialization Projects

This original contribution to practice explores the significance of schizophrenia spectrum disorder, one of the most severe psychiatric disorders recognized in the DSM-5. This condition affects over 50 million people worldwide and is amongst one of the most common psychiatric illnesses diagnosed in criminal responsibility evaluations to date. Nonetheless, there is limited comprehensive literature specifically examining the relationship between schizophrenia and the insanity defense. Information provided in this literature review aims to fill that gap and act as a resource for clinical forensic practitioners who may encounter related cases. Specifically, this document will begin by introducing schizophrenia spectrum disorder and …

Continuing To Do The Work: An Examination Of The Experiences Of Students Of Color In Collegiate Speech, Tennisha Sonsalla

All Graduate Theses, Dissertations, and Other Capstone Projects

This thesis examines how the experiences of students of color in the collegiate speech community are inextricably linked to their race. Students of color, unlike white students, face unique challenges in the predominately white speech community. Using qualitative interviews to uncover the experiences of students of color who have participated in collegiate speech, this project details 6 major themes: Internal Pressures, External Pressures, Navigating Voice, Issues of Representation, Team Dynamics, and Survival Strategies. As well as implications, limitations,and suggestions for future research.

Rehearsing With Imagined Interactions Theory: Exploring Imagined Interactions As Framework For Ensemble And Solo Performance Rehearsals, Joshua Hamzehee

National Forensic Journal

How should I practice is a common question that comes up while teaching performance and public speaking classes, when directing and performing in productions, and when coaching and competing for forensics squads. This essay provides a rationale for fusing Honeycutt’s imagined interactions theory (2003) with performance rehearsal processes, employing research guiding retroactive and proactive imagined interactions as a template to frame rehearsals that have the purpose of future actor ó spectator engagement. I use my experiences applying imagined interactions to an ensemble performance rehearsal and during a solo performance rehearsal to show the usefulness, limitations, and potentials of this methodological …

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.

Estimating The Sex Of A Skeleton Using Measurements Of The Femur: Assessing Accuracy Among People Of Different Ancestry And Historic Periods, Hannah Decker

Graduate Research Theses & Dissertations

Two of the most common elements used for sex estimation in humans are the pelvis and the skull, as measurements of these two regions can provide highly accurate results. However, in some forensic cases and archaeological sites, the skull and pelvis may be damaged or missing. As a result, it is important to develop methods for estimating the sex of an individual from other bones of the body. In this study, I specifically examined the femur and determined classification accuracy rates for six femoral measurements: the supero-inferior neck diameter, epicondylar breadth, vertical head diameter, transverse femoral head diameter, femoral shaft …
