How Gender Affirming Care Affects The Current Sex Estimation Standards In Forensic Anthropology: A Preliminary Study, Maggie M. Klemm

Anthropology Department: Theses

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 Non-Racial Approach To Assessing Group Membership Of Victims In A Mass Grave Using Cranial Data, John Albanese, Alyssa Di Iorio

Integrative Biology Publications

In some jurisdictions, race, ancestry, or population affinity have been used for historical and po-litical, rather than biological, reasons in forensic anthropology when identifying individuals. The approach persists even though the genetic and skeletal data clearly demonstrate that human variation does not cluster into these groups. For over 60 years, these methods have consistently performed poorly when independently tested using large samples. By racializing the deceased, these methods have further marginalized the living. However, there is a need in the investigation of genocide and human rights violations to demonstrate that a specific group was targeted. Without relying on the outdated …

Simulating Fluvial Transport Patterns Of Human Remains In The Tennessee River, Karli Palmer

Masters Theses

Law enforcement and search and recovery personnel often encounter difficulties when trying to determine where to find a decedent within an aquatic environment. Drowning, boating accidents, and other water related deaths are not uncommon. However, expensive equipment such as sonar and remote operated vehicles, or specially trained rescue divers are often required when searching for remains. Due to both public health and ethical concerns, there is a lack of controlled studies on aquatic decomposition and fluvial transport of human remains, which has contributed to the difficulty of predicting where remains in the water may be located. The purpose of this …

Reconsidering Scales And The Binary In Forensic Anthropology: A Critical Analysis Of Morphoscopic Data Utilized In Sex Estimation Standards., Bailey N. Watson

College of Arts & Sciences Senior Honors Theses

This research explores sex estimation standards used in forensic anthropology in an effort to further the conversation about forensic anthropology's binary-focused language and methods. Discussions regarding sex estimation methodology are important in light of gender variance in the general population. Presently, there is minimal published research on the identification of gender non-conforming individuals in forensic anthropology.

Two researchers individually assigned scores to features associated with sexual dimorphism in the os coxae according to existing methods for 253 individuals, equally represented by self- reported males and females. These data were statistically analyzed for correlation and overlap between features.

Results mainly point …

Combating Frailty: Application Of A Modified Skeletal Frailty Index In Modern Military And Civilian Populations., Emily M. Frazier

Electronic Theses and Dissertations

Conceptualizing, quantifying, and evaluating frailty in human skeletal remains is critical to understanding and interpreting physiological health and stress among past populations. While many researchers focus on frailty in bioarchaeological samples, developing models for mortality risk and individual- and population-specific indices of stress, no current methods directly address frailty in forensic contexts. This study considers the applicability of a modified index for assessing frailty in forensic anthropology by comparing distributions of 8 biomarkers of stress (linear enamel hypoplasia; periodontal disease; caries; osteoarthritis; intervertebral disc disease; rotator cuff disorder; antemortem fracture; and surgical procedure) using the original skeletal frailty index (SFI) …

A Preliminary Investigation Into The Effects Of Lucilia Sericata (Meigen) Blow Fly Larval Feeding On Sharp Force Trauma (Sft) Wound Patterns In Decomposing Bones Of Sus Scrofa Domesticus, Erica L. Klafehn

Student Theses

An important aspect of forensic investigations involves the characterization and analysis of bone related trauma as this can provide valuable information regarding the manner and circumstances of death. Bone trauma can be classified into three main categories, which include Sharp Force Trauma (SFT), Blunt Force Trauma (BFT), and Gunshot Trauma. Previous experiments have explored SFT on flesh and bones, specifically made with knives or saws, coupled with various microscopic analytical methods. Minimal research has been done integrating both a forensic entomology and forensic anthropology approach, so it is imperative to understand previous literature detailing the behaviors of insects (blow flies), …

Detecting Gsr Indicative Particles On Decayed Bones Using A Novel Field Kit, Sven Engling

Student Theses

Decomposed human remains are complex forensic puzzles, escalating in difficulty as the remains’ age obscures evidence, like trauma. Research has shown that scanning electron microscopes with energy dispersive X-ray spectrometers (SEM-EDX) are capable of detecting and identifying gunshot residue (GSR) particles on bones. However, SEM-EDX work is time consuming, expensive, and not accessible to every forensic department. Therefore, a preliminary field test capable of detecting GSR indicative particles, like lead, could save departments money and assist in trauma identification. This study examines the viability of using either the 3M Lead Check Test swabs or a sodium rhodizonate solution as part …

Multi-Agent Scavenging Patterns In Hawai‘I: A Forensic Archaeological And Skeletal Case Study, Jennifer F. Byrnes, William Belcher

Department of Anthropology: Faculty Publications

Knowledge of the behavior of local fauna can aid forensic investigators in developing awareness of site formation processes. In Hawai‘i, little has been published on the effects of feral domestic pig (Sus scrofa) and feral domestic dog (Canis familiaris) scavenging and bone dispersal on field recovery and laboratory observations. In this Pacific tropical setting, the most consequential terrestrial taphonomic agents are pigs and dogs, both in terms of hard tissue modification and dispersal of remains across the landscape. In 2017, an archaeologist discovered the remains of an unidentified decedent on the island of Kauaʻi, State of Hawai‘i during a cultural …

Assessing The Precision Of Cranial And Mandibular Morphoscopic Traits From 3d Surface Scans, Sarah Thomas Schwing

Masters Theses

Virtual anthropological (VA) methods have been successfully used to capture metric data in the form of standard caliper measurements as well as volumetric data from various human skeletal elements. Virtual anthropological investigations of morphoscopic traits have increased over the past two decades, however, greater attention has been paid to investigations of metric data and to the use of CT technologies. Few studies have focused on morphoscopic data and fewer have employed 3D surface scans in data collection. Morphoscopic VA studies largely pertain to age estimation using the os coxa; fewer pertain to sex estimation and, to the author’s knowledge, no …

Mapping Louisiana's Missing: Spatiotemporal Profiling Of Louisiana's Missing Persons- An Experimental Application Of Geographic Information Systems And Forensic Anthropology, Liam J. Johnson

LSU Master's Theses

The growing number of unresolved unidentified and missing persons cases in the United States is this nation’s ‘silent mass disaster’ (Ritters, 2007). In addition to contextualizing biocultural traits of these cases, forensic anthropologists are uniquely qualified to address this underrecognized humanitarian crisis due to their proven ability to bridge conflicting stakeholders in often complex sociopolitical environments and to create improved opportunities for community collaboration. This project explores local and state demographic trends of missing persons cases and how this information can be used to assist investigative agencies with their missing population, analyzes gaps in identification data, and selects optimal locations …

Archaeology Or Crime Scene? Teeth Micro And Macro Structure Analysis As Dating Variable, Jessica A. Vincenty

Student Theses

Simple methods to aid in the determination of forensic or archaeologic relevancy of skeletonized remains have been researched since the 1950s. With advances in microscopic imaging techniques and machine learning computer data analysis methods the relevancy of decontextualized, comingled remains has room for improvement. This thesis is a study done to pioneer a new approach to analyzing dental skeletal remains to determine forensic relevancy.

Archaeological dental samples collected from the ancient city of Ur in modern day southern Iraq in addition to modern dental extractions were processed for scanning electron microscopy imaging. Archaeological and modern samples displayed different surface and …

Analyzing Lower Extremity Injury Profiles Of Pedestrian Traffic Fatalities According To Vehicle Type, Jacqulyn M. Scheer

Cal Poly Humboldt theses and projects

Skeletal trauma analysis of motor vehicle collisions has the potential to support or contradict reported collision circumstances. This project analyzed the skeletal injuries that pedestrians sustain in fatal collisions according to vehicle types (car, truck, SUV, van, bus, semi, etc.). Data were collected from reports and databases related to cases that occurred in King County, Washington. The pelvis and lower extremities of the body were analyzed for the frequency of skeletal fractures, grouped by pelvis, femora, patellae, tibiae, and fibulae skeletal groups. A Kruskal-Wallis test showed an overall no significant difference (P<0.05) in fracture quantity in skeletal regions between different vehicle groups. A multiple pairwise comparison using Dunn’s procedure also found no significant differences between vehicle type groups. A Partial Least Squares Discriminant Analysis showed an overall success rate of 37.29% when classifying injury profiles to vehicle type. The findings of this project can be applied to further research into the skeletal analysis of automobile versus pedestrian collisions. Low classification rates suggest that fracture frequency alone should not be used to assist in associating injuries with potential vehicle types in medicolegal investigations. Rather, the findings of this project lead the researcher to recommend that investigators and forensic practitioners move towards standardization in the quality and type of collected data—specific recommendations being the collection of actual speed and inclusion of full-body imaging in postmortem examinations to enable more detailed analyses.

Assessing Methods For Estimating Biological Sex From Subadult Skeletal Elements, Dorota Zabnicka

Cal Poly Humboldt theses and projects

While methods for estimating the sex of adult skeletons are relatively accurate, these methods are often inconclusive when applied to subadults (non-adults), especially when many secondary sexual characteristics have not fully developed. Furthermore, existing methods for subadults are often tested on samples with relatively homogenous ancestries, calling into question their reliability in more diverse populations. This thesis reviewed techniques for estimating sex in subadult skeletal remains, and the most promising methods were retested on individuals of known sex between ages 3 and 17 years (n=39, 14 males, 25 females) from the Hamann-Todd Osteological Collection. Data collection included measurements of the …

Alas, Poor Yorick: A Dna Analysis Of Ancestry Using Crania, Claire Hanson

Graduate Student Theses, Dissertations, & Professional Papers

Current methods for estimating ancestry in biological profiles provided to law enforcement and forensic collections rely heavily on the use of metric and non metric methods such as FORDISC 3.1 and “trait lists.” The reliance on these methods has led to inaccurate and ambiguous ancestry estimations, as many metric and non metric methods are subjective and cannot be statistically tested for error rates. As a result, forensic collections, such as the University of Montana Forensic Collection, could potentially house remains that have been inaccurately curated. In order to test the accuracy of curation in the UMFC, DNA samples were extracted …

A Comparative Analysis Of Homicide Rates Utilizing The University Of Tennessee Forensic Data Bank, Anna F. Hampton

Graduate Student Theses, Dissertations, & Professional Papers

Homicide has piqued the interest of society through media not only in the 21^st century, but also dating back to the 1800s with crime fiction novels. Homicide holds the attention of our society with crime drama television series and has become part of American culture. With the attention that homicide receives, studies focusing on homicide are therefore important. This research utilizes the University of Tennessee Forensic Data Bank (FDB) to examine and compare homicide rates to the Global Study on Homicide conducted by the United Nation Office on Drugs and Crime (UNODC). Variables examined include sex, ancestry, cause of …

Sexual Dimorphism In Skeletal Trauma Associated With Intimate Partner Violence (Ipv), Keith Biddle

Graduate Student Theses, Dissertations, & Professional Papers

Once known as “Domestic Violence”, Intimate Partner Violence, or IPV, is a problem as old as humanity. Even in our modern era, it continues to plague even the most “enlightened” or “advanced” cultures and societies. Much has been written about the issue from Sociological and psychological aspects and while there is some consensus in the medical field regarding the patterns of injury associated with IPV, that consensus has yet to reach the field of forensic anthropology. It is to this end that this study has been conceived.

The proposed project has three parts. The first part is a validation study …

New Approaches To Juvenile Age Estimation In Forensics: Application Of Transition Analysis Via The Shackelford Et Al. Method To A Diverse Modern Subadult Sample, Kelly R. Kamnikar, Nicholas P. Herrmann, Amber M. Plemons

Human Biology Open Access Pre-Prints

Dental development is one of the most widely utilized and accurate methods available for estimating age in subadult skeletal remains. The timing of tooth growth and development is regulated by genetics and less affected by external factors, allowing reliable estimates of chronological age. Traditional methodology focuses on comparing tooth developmental scores to corresponding age charts. Using the Moorrees, Fanning, and Hunt (MFH) developmental scores, Shackelford and colleagues embed the dental development method in a statistical framework based on transition analysis. They generated numerical parameters underlining each “stage” and age-at-death distribution and applied them to fossil hominins and Neanderthals with limited …

A Forensic Investigation Into The Possible Origins Of Three Human Skeletons, Jefferson P. Sinnott

Forensic Science Theses

The Anthropology Department at Buffalo State has three human skeletons that have been part of the department’s collection for several years. The origin of the skeletons is currently unknown. Modern DNA techniques coupled with forensic anthropological techniques may now allow us to determine with some certainty the geographic origin of the skeletons. Ancestry, sex, age, and stature were assessed using current anthropological techniques. Afterwards, one tooth from each of the three skeletons was extracted, pulverized and DNA was isolated. Y-STR fragment size analysis of the DNA samples can provide information about the patrilineage of male individuals. Mitochondrial DNA sequencing analysis …

United States-Mexico Border: Rights Of The Dead, Forensic Anthropologists, And Families Of The Victims, Diana A. Newberry

Cal Poly Humboldt theses and projects

From 1998-2018, over 6,000 migrants have been found dead after attempting to cross into the United States through its southern border; most of the deaths are due to harsh environmental conditions found through the crossing areas. Migrant remains are often found with no belongings or evidence to use to identify the deceased. Forensic anthropologists, medicolegal examiners, and non-governmental organizations such as Humane Borders, Águilas del Desierto [Eagles of the Desert], and the Colibrí Center for Human Rights have worked to recover, identify, and repatriate these remains. To understand the many facets of this process, this thesis explored the relationships between …

The Influence Of Body Size On Sexual Dimorphism, Haley Elizabeth Horbaly

Masters Theses

Accurate sex estimation of human skeletal remains is imperative for skeletal biologists, and relies upon the sexual dimorphism between males and females in a population. The degree of dimorphism, and hence the accuracy of sex estimation methods, are known to vary among populations, and while such global patterns have been well studied, the underlying causes of this variation are relatively unclear. Body size—a sexually dimorphic trait that also varies among populations—has previously been shown to affect skeletal morphology, yet whether specific body size parameters, such as stature and body mass, influence the expression of traits used for nonmetric sex estimation …

An Exploration Of The Effects Of Taphonomy On Isotope Ratios Of Human Hair, Tiffany Bivens Saul

Doctoral Dissertations

Isotope analyses of human remains have been conducted with growing frequency over the past thirty years in anthropology, in both archaeological and forensic contexts. Analyses of isotope ratios of elements such as carbon, nitrogen, hydrogen, oxygen, and strontium from teeth, bones, and hair have provided information regarding individual diet and geographic movement during different life stages. Hair grows at a predictable rate and provides a serial recording of diet and travel history for the weeks and months just prior to death. What has not been systematically studied is whether postmortem decompositional changes to the body have an effect upon isotope …

Geographic Information Systems (Gis) And Predictive Modeling Of Body Disposal Sites, Annemarie Catherine Gundel

Masters Theses

Homicide victims are often discovered by accident or located through witness testimony, both of which are unreliable methods. Moving a victim’s body from the scene of the crime to a secondary disposal site may further complicate their discovery, delaying recovery, identification, and evidence collection. Homicides are exponentially more difficult to investigate, solve, and prosecute without a body. In the medicolegal context, a body disposal site prediction model is an alternative to relying on luck or witness testimony. Predictive models were created using body disposal data collected from the Office of the Chief Medical Examiner (OCME), Connecticut, to explore the feasibility …

Identity By The Numbers: Cancerous Lesions And Likelihood Ratios, William Daniel Cawley

Masters Theses

The use of Bayesian theory has been gaining popularity within the forensic anthropology community for its ability to model the way in which decisions are made based upon varying levels of confidence. However, many forensic anthropologists have been reticent to adapt Bayesian approaches given the general lack of knowledge in regards to this approach (Konigsberg and Frankenburg, 2013:153). The purpose of this thesis is to demonstrate how the application of an establish Bayesian framework can be used to determine likelihood ratios representing the probative value of skeletal lesions consistent with cancer for use in forensic personal identification. To do this, …

Juvenile Remains: Predicting Body Mass And Stature In Modern American Populations, Erin F E Pinkston

Cal Poly Humboldt theses and projects

There are increasing numbers of unidentified persons in the U.S. and abroad. To generate positive identifications, forensic anthropologists and others working in the medicolegal field employ a variety of methods to produce biological profiles to match to case files and missing persons databases. Body mass, and stature are two important components of a biological profile, and both can be estimated using regression formulae derived from skeletal metrics. In cases of unidentified juvenile remains, these are particularly important metrics, as it is difficult or impossible to determine sex in prepubescent remains, and the quality of ancestry estimation is currently under debate …

The author’s research focuses on the traumatic injuries and demographics of the remains at Choeung Ek, while also incorporating cultural …

The Evaluation And Refinement Of Nonmetric Sex And Ancestry Assessment Methods In Modern Japanese And Thai Individuals, Sean D. Tallman

Doctoral Dissertations

Effective biological profiles in forensic anthropology and bioarchaeology depend on the development, validation, and refinement of population-specific methods. However, most methods were developed in North America on individuals of African and European descent, and it is unlikely that such methods can generate accurate biological profiles for Asian individuals. Moreover, Native Americans have served as biological proxies for Asians due to their distantly shared genetic history, resulting in largely untested assumptions that Native Americans and Asians are homogenous and share nonmetric sexually dimorphic skeletal features and a unique suite of cranial traits that can be used in ancestry assessment.
