Stop Blaming My Users: Illumination Of The Technocentric Mythos Bias, Ervin H. Frenzel, Richard Lightcap

Journal of Cybersecurity Education, Research and Practice

 Abstract -This conceptual essay addresses the need for systemic and systematic transdisciplinary analytical techniques within cybersecurity and technical security. This conceptual essay is contingent upon recognition that cybersecurity is not simply technical in nature, it does not need an adversary, and more importantly it is based upon systems engineering and systems thinking.  The essay contributes a socio-technical attribution chain and field-specific ontology/taxonomy which distinguish user-triggered events from root causes, latent conditions, technical debt, validation failures, governance failures, and attribution bias before assigning responsibility to end users. It systematically defines an ontology inclusive of developer technical debt, organizational debt arising from …

A Qualitative And Quantitative Comparative Analysis Of Ballistic Bone Trauma From Frangible And Full Metal Jacket Projectiles, Hajar S. Hassan

Student Theses

Ballistic bone research is essential as 90% of homicides with the use of a firearm include injuries to bone. Forensic anthropologists use ballistic bone trauma to gather details and reconstruct an event, but ballistic bone trauma depends on many intrinsic and extrinsic factors. These factors include the type of bone, the type of firearm, and the type of ammunition. As new ammunition and firearms emerge, the literature on ballistic bone trauma remains limited. This novel study compares the bone trauma from the most common projectile, the full metal jacket, to a frangible projectile which is made to break upon impact. …

From Prairie To Practice: Forensic Taphonomy, Ethics, And Regional Ecology In Southeastern Nebraska, Jessica F. L. Gammage

Department of Anthropology: Theses and Student Research

Forensic taphonomy examines the postmortem processes that affect human remains within specific environmental contexts and plays a critical role in medicolegal death investigation. Despite significant advances in decomposition research, experimental studies remain geographically and environmentally uneven, limiting the transferability of postmortem interval (PMI) estimation methods across regions. The Central Great Plains are underrepresented in forensic taphonomic research despite its distinct ecological and geomorphological characteristics.

This thesis evaluates southeastern Nebraska as a specific regional setting for forensic taphonomic research by integrating ecological, pedological, and geomorphological data with current forensic literature. Tallgrass prairie vegetation, loess-derived soils, seasonal moisture variability, and dynamic fluvial …

Understanding Roma Oppression In Europe Through Humantarian Forensic Analysis, Christal L. Quinn

Department of Anthropology: Theses and Student Research

This thesis examines the marginalization of Roma people in Europe, and how humanitarian forensic practices may help Roma communities in their quest for justice and recognition. The study draws exclusively on secondary information to examine the social, political, and legal issues affecting the Roma communities, who have endured centuries of institutional discrimination, marginalization, and violence. This thesis identifies ways in which systematic oppression continues to limit Roma communities’ access to education, housing, healthcare, and legal protection through a review of relevant literature and applicable theoretical frameworks. The study also examines the relevance of forensic science, particularly its humanitarian applications, in …

Rehumanizing Anatomized Individuals: Using Osteobiographies As A Step Towards Reparative Justice, Lillie C. Turpin

Department of Anthropology: Theses and Student Research

In 1985, India banned the export of human remains. This ended the major trade route for primarily US and European anatomical supply companies. Until this point, companies like Carolina Biological Supply exploited and erased vulnerable people's identities, molding them into anonymous anatomical specimens. This study investigates the life and postmortem history of twenty-five individuals, previously used as anatomical specimens, housed at the University of Nebraska–Lincoln. Using an osteobiographical approach, this research reconstructs aspects of these individuals' lived experiences and examines how anatomical preparation practices reflect structural violence and apathy.

Skeletal analysis of twenty-five individuals revealed a range of biological profiles, …

Non-Destructive Automated Classification Of Human And Large Mammal Long Bone Fragments: A Deep Learning Approach Using Micro-Ct Histomorphology And Grad-Cam Interpretation, Kathleen Marie Kelley

Department of Anthropology: Theses and Student Research

This study explores the development and validation of an automated, deep learning system designed to differentiate human from large mammal long bone fragments using micro-CT imagery. A comprehensive dataset of cross-sectional µCT images was assembled from human and animal skeletal material processed at the DPAA, Nebraska. A convolutional neural network (CNN) based on a ResNet-18 architecture, utilizing transfer learning from ImageNet weights, was trained to classify µCT images as human or animal. The model achieved a mean classification accuracy of 89.85% (± 8.27%) across five sample-level cross-validation folds, with a sensitivity of 96.21% and a 95% bootstrap confidence interval of …

Decomposition Study Using Pigs In Southeastern Nebraska During The Fall And Winter Seasons, Ryan Bodine

Department of Anthropology: Theses and Student Research

When an individual is found deceased, one of the tools used in the identification process is estimating the post-mortem interval (PMI). This estimate is used to determine how long an individual has been deceased once their remains are found. To estimate an accurate PMI, knowing how decomposition is affected by external factors is key. The transition period from fall to winter in southeastern Nebraska consists of fluctuating temperatures as the seasons transfer from fall to winter. This thesis investigates how decomposition is affected during this transition period while also looking at two different environments that are common in Nebraska, prairies …

Exploring The Biocultural Profile Of The Undocumented Populations Of The Sonoran Corridor: A Skeletal Assessment Of The Prevention Through Deterrence Strategy, Mary A. Vaughn

Department of Anthropology: Theses and Student Research

Over the last thirty years the mortality rate of the undocumented population at the US-Mexico border has risen, requiring methods distinguishing US-born individuals from immigrants to improve the likelihood of identification and repatriation through foreign consulates. Forensic anthropologists with the Pima County Office of the Medical Examiner (PCOME) have advocated for the use of the biocultural profile, combining the biological profile with factors including oral health, osteological stress, and personal effects. The biocultural profile serves two purposes, functioning both as a tool for identification and with which to document structural inequality within communities of origin.

This study examines changes in …

Investigating The Relationship Between Noun Classes And Plant Folk Taxonomy In Chasu Language Of Kilimanjaro Region In Tanzania, Peter Rabson Mziray

Journal of Humanities and Social Sciences

The current study investigates the relationship between noun classes and plant folk taxonomy in Chasu (G 22). The study focuses on two objectives: the first objective is to describe the plant folk taxonomy in Chasu and the second objective is to determine the relationship between noun classes and plant folk taxonomy in Chasu. Data were collected from rural villages in Same and Mwanga districts by using free listing, field interviews (jungle-walk-and-identify), and written texts containing Chasu plant names. The findings reveal that Chasu folk taxonomy reflects different ethnobotanical categories; including a unique beginner which is mmea/mimea ‘plant(s)’, and three life …

The Normalization Of Clandestine Graves In Mexico, Alejandra Vela

Themis: Research Journal of Justice Studies and Forensic Science

Clandestine graves are increasing at an alarming rate in Mexico, as cartels fight for dominance over the wealthiest territories. Those who fall victim to cartels are brutally tortured into submission or are murdered and disposed of. These graves are the preferred method of body disposal by the cartels. By disposing of various victims in hidden locations, the cartels seek to erase the existence of these individuals. Victims are reduced to only bone fragments and ash. Friends and family of those who have gone missing have created a large search organization, Madres Buscadoras, to combat the helplessness of authorities. Madres Buscadoras …

Heat Induced Diagenesis And Osteometrics: An Experimental Approach To Assessing Thermal Alterations To Forensic Anthropological Data On Dry Bone, Audrey Holbeck

Department of Anthropology: Theses and Student Research

Fire appears in forensic casework in instances of arson, vehicle fire, house fire, to conceal evidence, or, in increasing contemporary frequency, wildfire, as a result of climate change. Thermal alteration is a destructive process to osseous material and can impact the accuracy of identification methods and trauma analysis by alteration of the structure, appearance, and morphology of human remains. This study seeks to validate previous research on the metric and morphological changes bone undergoes when exposed to extreme heat, and how that may impede estimation of metric features such as stature. Three long bones, a humerus, femur, and tibia, from …

Comparative Analysis Of Gunshot Trauma And Decomposition In Southeast Nebraska, Alexandra C. Tieken

Department of Anthropology: Theses and Student Research

Accurately identifying gunshot trauma (GST) in forensic anthropology remains a significant challenge, particularly in distinguishing the effects it has on decomposition. This study investigates how different types of gunshot trauma influence the rate and characteristics of decomposition in a humid continental climate, specifically southeastern Nebraska. Utilizing Sus scrofa domesticus (domestic pigs) as human proxies, four pigs were euthanized by professionals and subjected to controlled conditions at the Reller Prairie Field Station. Three pigs were inflicted postmortem with close-range gunshot trauma using a 9mm handgun, a 12-gauge shotgun, and an AR-15 rifle, while a fourth served as a trauma-free control. For …

Wildfire And Decomposition: A Taphonomic Analysis Of Thermal Alterations And Decomposition, Ashley Novak

Department of Anthropology: Theses and Student Research

Within the field of forensic anthropology, practitioners may be faced with remains that have been thermally altered by thermal alterations caused by wildfire. Within the field, very little research has been conducted examining how these thermal events impact rates of decomposition. While research has been conducted generally on the effects of thermal alteration on decomposition, these studies do not look through this lens and provide answers to the question of how do thermal alterations caused by wildfires affect rates of decomposition? This research examines the effects of thermal alteration caused by wildfire on the rate of decomposition. A decompositional study …

Firearm Trauma Across Time: Investigating Civil War Gunshot Trauma And Their Impact On Modern Forensic Analysis, Morgan K. Reeder

Department of Anthropology: Theses and Student Research

This thesis will examine the ballistic trauma caused by Civil War-era firearms and ammunition. These weapons, each with distinct characteristics, had a profound impact on the nature of combat and the resulting injuries. By investigating how these firearms’ ammunition interacted with human bone structure, this research will offer a detailed analysis of the trauma these weapons produced.

This research intends to answer several key research questions. First, how did the different types of Civil War firearms affect skeletal remains? Second, what are the key characteristics of gunshot trauma caused by these firearms in terms of bone fracturing and fragmentation, and …

Trends In Dna Aanalysis To Determine Postmortem Interval: A Systematic Lilterature Review, Victoria S. Kashkin

Department of Anthropology: Theses and Student Research

Forensic taphonomy is a recently popular field within forensic anthropology with limited research in the Central Great Plains. Given decomposition varies by region, more studies must be done to understand aspects of decomposition in this region. However, it is one of the most important subfields of forensic anthropology since determining postmortem interval (PMI) is extremely important to successfully identifying a missing individual if other indications of who the individual is are nonexistent. In this study, a systematic literature review was conducted to answer what trends are seen in research being done for using DNA to determine PMI, and what methods …

Military Forensic Archaeology: The Process And Recovery Of U.S. Missing-In-Action (Mia) Service Personnel, William Belcher, Luann Wandsnider, Ella N. Axelrod, Finn Kennison, Alicia Lawson

Department of Anthropology: Faculty Publications

The United States (U.S.) Department of Defense's (DoD) Defense POW/MIA Accounting Agency (DPAA) is the largest skeletal identification laboratory in the world and receives several hundred cases per year for identification related to Missing-in- Action (MIA) U.S. service members. While there are various sources for these accessions, by far the largest source is through unilateral or bilateral (done in cooperation with another governmental entity or nongovernmental organization) as well as public-private partnership excavations. While the DPAA-style military forensic archaeology follows archaeological principles and recording standards, the work is goal-oriented, evidence/trace-driven, and time-constrained— a common occurrence with cultural resource management sites …

Review Of Digging For The Disappeared: Forensic Science After Atrocity, Abigail Vaughn

Nebraska Anthropologist

Since the field's development, individuals and communities involved in and affected by international forensic investigations have been confronted with many political and ethical dilemmas. The book, Digging for the Disappeared: Forensic Science After Atrocity (2015), by Adam Rosenblatt, attempts to identify and articulate the various debates surrounding humanitarian forensic work. In doing so, the author focuses on four key areas; the purpose of such investigations, the stakeholders and expectations involved, and what may realistically be accomplished. While sympathetic to the perspective of forensic practitioners, Rosenblatt presents the positions of all parties in an unbiased manner, introducing the reader to …

Application And Implications Of Radiocarbon Dating In Forensic Case Work: When Medico-Legal Significance Meets Archaeological Relevance, Benoit Bertrand, Thibault Clauzel, Pascale Richardin, Anne Bécart, Philippe Morbidelli, Valery Hédouin, Carina Marques

Anthropology Faculty Publications

The estimation of the postmortem interval for skeletal remains is a crucial aspect of forensic anthropology. This paper illustrates the importance of radiocarbon analysis for establishing medico-legal significance and supporting forensic identification, through the analysis of three case studies for which the years of both birth and death were investigated. In Audresselles, Northern France, a partial skull was discovered with no contextual information or identity. Radiocarbon dating yielded an average calibrated calendar age of 4232 BCE (92.5% probability), indicating significant archaeological value but no forensic relevance. In the second case, skeletal remains were found in the flooded underground of a …

The Limitations And Future Of Isotope Analysis In Forensic Anthropology, Kris Weller

Themis: Research Journal of Justice Studies and Forensic Science

This research paper will discuss the applications of isotope analysis in forensic anthropology, focusing on the limitations of this technique and its potential future uses. Isotope analysis is based on the principle that isotope ratios vary across geographic regions and that humans incorporate those unique isotope ratios into their bodies when they eat and drink. Forensic anthropology uses isotope analysis to determine a decedent’s approximate region of origin or residence. It is especially in cases where the remains are partially or highly decomposed, and when other avenues of investigation have been exhausted. In its current form, the applications of isotope …

Adults Matter Too: An Examination Of State Adult Missing Persons Policies And Procedures To Implement A Best Practices Handbook, Hunter Smith

Honors Theses

The most recent estimates put the number of active missing person records at 97,127. Over the past eight years, child active records have decreased by 2,530, while adult active records have increased by 14,696. While there is no clear explanation for this trend, a common theory is that there are multiple federal and state laws requiring the entry of missing people under the age of 2; however, very few, if any, extend to adults. Additionally, there is a lack of standardization across available policies and procedures for where these cases should be reported, the time frame for doing so, and …

How Gender Affirming Care Affects The Current Sex Estimation Standards In Forensic Anthropology: A Preliminary Study, Dakota Taylor

Department of Anthropology: Theses and Student Research

Current sex estimation standards in forensic anthropology are based on individuals whose gender matches their biological/osteological sex, also known as Cisgendered individuals. Recently, transgender individuals have started to become more common in the forensic context due to the increase in hate crimes and violence. This research builds upon past research done on how facial feminization surgery can affect both visual and metric methods, where it was found that forensic anthropologists should rely on the visual methods if they suspect someone to be transgender due to it being more accurate and being able to clearly state the scars left on the …

Numerical Variations In The Thoracic And Lumbar Vertebrae Within The John A. Williams Skeletal Collection, Western Carolina University, Cullowhee, Nc (Usa), Leanna Annette Sanford

Department of Anthropology: Theses and Student Research

This research is on how human variation can lead to the identification of remains based on skeletal variation. The data were collected by performing a morphoscopic trait study of the John A. Williams (J.A.W.) Documented Human Skeletal Collection at Western Carolina University in Cullowhee, NC (USA). Morphoscopic traits are nonmetric traits, visually identified using the knowledge of osteology. The study was performed to study variation of the vertebral column, specifically focusing on morphoscopic traits of the thoracic and lumbar vertebrae. The focus of this research is centralized on the presence of numerical variations in the vertebral column such as eleven …

The Osteobiography Of Human Remains From The Seaview And Indian Town Trail Archaeological Sites, Maggie M. Klemm

Department of Anthropology: Theses and Student Research

Extensive site surveys and excavations on the Island of Barbuda led by Sophia Perdikaris have identified over 62 sites spanning from the Archaic time period to Historic times. Over the last 18 years, these multidisciplinary teams have focused on mapping all sites and performing rescue excavations on sites threatened by sea level rise, erosion or development. Two such sites are the Saladoid site of Seaview (BA016) and the Troumassoid site of Indian Town Trail (BA01). The dunes surrounding the site of Seaview receive the brunt of storms and hurricanes. In 1998 hurricane Georges exposed skeletal material now part of the …

A Manual On The Planning And Integration Of Archaeological Methods In To Outdoor Forensic Search Investigations, Jonathan Robert Garcia

Department of Anthropology: Theses and Student Research

As archaeology and its applications into forensic contexts develop into the growing discipline of forensic archaeology, an increasing amount of literature has resulted stemming from research on the integration of common archaeological methods. However, much of this literature is intended for professional archaeologists or forensic anthropologists who are well experienced in their respective disciplines. Emerging literature generally does not consider those who leads efforts at forensic scenes in the outdoors such as law enforcement officers who often lack a background in archaeology or forensic anthropology. This thesis seeks to resolve this dilemma by creating a new and accessible manual. The …

Understandings Of Vulnerability And Social Determinants Of Health In Forensic And Expert Social Anthropology: A Scoping Review, James W. W. Rose, David M. Tran

The Qualitative Report

Forensic and expert social anthropology (FESA) is a branch of social anthropology that specialises in the provision of evidence to legal-administrative processes, which are overseen by courts and other legally empowered bodies, and which give regard to the social cultures of legally and administratively involved individuals and communities (LAIICs). Despite a preoccupation with political advocacy in the broader philosophy of social anthropology, FESA literature does not typically give regard to LAIIC vulnerability defined qualitatively in terms of social determinants of health, including physical, mental, and social well-being. This paper presents findings from a JBI/PRISMA-ScR scoping review of n=1,674 texts, identifying …

Forensic Archaeology Protocols For Wildfires And Fire Related Scenes, Erik Schulz

Nebraska Anthropologist

Forensic Archaeology Protocols for Wildfires and Fire-Related Scenes

Forensic archaeology is a relatively new area of study and focuses on the medical legal aspects of archaeology. This paper will focus on how forensic archaeology should be used for wildfire and other fire-related fatalities or investigations, what happens to bone when exposed to heat, what protocols should be in place and how an excavation should look, and finally the challenges of fire-related investigations. This report will focus on the larger scale of the investigation and will be using several sources from different wildfire and fire fatality reports.

Inter- And Intra-Observer Error In Forensic Anthropology: Based Upon Langley Et Al. 2016 Data Collection Procedures For Forensic Skeletal Material 2.0 For The Cranium And Femur, Maggie M. Klemm, Dakota L. Taylor

Nebraska Anthropologist

Following the Daubert v. Merrell Dow Pharmaceuticals (1993) ruling three decades ago, guidelines were established for determining the reliability and validity of expert testimony in court. These guidelines include considerations of whether the theory and methodologies employed have been tested, the establishment of potential or known error rates, and the existence and maintenance of the standards (Christensen, 2004). Testifying in court as an expert witness has become a critical role as a forensic anthropologist. As such, the methodologies, techniques, and standards utilized by forensic anthropologists must be carefully considered and adhere to the Daubert guidelines within the court system. One …

Cheiloscopy Examination And Classification Of Lip Prints With And Without Parafunctional Oral Habits: A Cross-Sectional Observation Study, Emily Smith Regan

Dental Hygiene Theses & Dissertations

Problem: Lip prints are unique and have potential for use as a human identifier. The purpose of this study was to observe possible cheiloscopy differences of individuals with and without parafunctional oral habits. Additionally, inter-rater reliability (IRR) of lip print examiners was observed. Methods: This IRB approved blinded cross-sectional observational study collected lip prints from sixty-six individuals using lipstick and adhesive tape to transfer lip prints to white bond paper for viewing purposes. Each set of included lip prints was divided into quadrants and dichotomized as those with or without an oral parafunctional habit. Each quadrant sample was manually analyzed …
