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) …

Tooth Crown Morphology And Testosterone Transfer In Female Members Of Opposite-Sex Dizygotic Twin Pairs, Randall Feezell

Graduate Theses and Dissertations

The twin testosterone transfer (TTT) hypothesis posits that females gestated with male co-twins develop more masculine phenotypes due to in-utero androgen exposure. Research has shown co-gestational effects to be associated with increased deciduous and permanent tooth size in females belonging to opposite-sex dizygotic twin pairs (OSF) as compared with females belonging to same-sex monozygotic (MZF) and dizygotic (SSF) twin pairs and female siblings. This study evaluates whether the TTT hypothesis explains patterns of dental morphological variation, namely differences between OSF and other females (SSF, MZF, female siblings) in a contemporary sample that includes both deciduous and permanent data. This work …

Musculoskeletal Markers: A Comparison Of The Influence Of Three Biological Factors On Robusticity, Megan Greene

LSU Master's Theses

Research suggests that musculoskeletal markers (MSMs) can provide information about the lives of deceased individuals. The majority of studies focus on single factors that influence the morphology of MSMs in pre-modern societies (i.e., medieval, hunter-gatherers, preindustrial, etc.). This study analyzes MSMs of modern skeletons of 72 females and 83 males from the United States whose ages at death range from 30 to 89 to understand the relationship between various biological factors and MSM morphology. Eight MSMs (attachments of pectoralis major, deltoid, brachialis, supinator, iliopsoas, gluteus maximus, quadriceps, and soleus) were analyzed and categorized as phases zero, one, two, or three …

Assessing The Effect Time And Burial Environment Have On The Use Of The Lamendin Dental Age Estimation Method In Two Archaeological Samples From Jordan, Sabrina L. Williamson

LSU Master's Theses

The Lamendin method is a dental age estimation method that can be used by biological anthropologists when the skeletal anatomy is not available. The Lamendin method utilizes an index derived from measurements of the tooth root height (RH), periodontal line height (PLH), and root transparency height (RTH) to estimate the age of an individual. Although this method is often used in forensic contexts, its presence in the bioarcheological literature is almost non-existent. Research that mentions the Lamendin method conflict about whether the method can be used in specimens with longer postmortem intervals (PMIs) and in various depositional environments. This study …

Analysis Of Vertebrae Pathologies Of Grave A650 Chryssi Island, Crete, Greece, Abbey E. Bartmess, Susan Kirkpatrick Smith

Symposium of Student Scholars

This study of multiple, co-mingled adult individuals located in grave A650 on Chryssi Island, Crete, Greece, examines the prevalence of several pathologies of the vertebrae. This grave was built into a collapsed Late Minoan period house (1400-1100 B.C.E.). Grave A650, which likely dates to the 5th – 7th century C.E., shows evidence of being used over a long period of time and may have served as an ossuary. The pathologies of approximately 30 recovered vertebrae, both complete and incomplete, show signs of degenerative joint disease, spondylolisthesis, and body expansion. Researching this data aims to accomplish a comprehensive understanding of what …

Dating The Seals Of Harappa: A Radiocarbon Approach, Grace Abernathy

Symposium of Student Scholars

For many years, Indus seals have puzzled archaeologists with their detailed motifs and undeciphered script. There is no pattern to the relationship between motifs and inscriptions, as each motif has been found scattered across the greater Indus region. In looking at the context of the seals and radiocarbon dating of charcoal, bone, and shell in a singular site, there may be a definitive pattern between certain motifs and the time periods they were used. This study uses contextual analysis to identify chronological patterns of seals discovered at the site of Harappa. Should any patterns arise, this research study could be …

Dismantling Binary Assumptions In Sex Estimation: Uplifting Trans And Gender Diverse Identities In Forensic Anthropology, Audrey Holbeck

Honors Program: Senior Projects (Public)

Forensic anthropology is a study within the field of physical anthropology that seeks to apply osteological expertise to legal and criminal situations. One of a forensic anthropologists’ most important jobs is to build a biological profile, consisting of age, biological sex, stature, and ancestry, in correspondence to an unidentified decedent. As we enter the third decade of the 21st century, instances of violence against trans and gender non-conforming individuals are unfortunately prominent, however, there has also been more awareness shed on trans activism. Trans individuals are at a higher risk of being victims of violent crime, and thus, forensic anthropologists …

Remote Analysis Capabilities Of Digitally Rendered Models Of Human Remains: Obtaining Osteometric Data & Assessing Pathology And Taphonomic Alteration - Using Non-Human Animal Remains As An Analogue, M. Elizabeth Dyess

2022 Symposium

Computed tomography (CT), photogrammetry, and laser surface scanning technologies have enabled remote, noninvasive, and non-destructive analysis of skeletal human remains in various contexts. Such technologies have found applications in the disciplines of osteoarchaeology, forensic anthropology, the medical sciences, and other related fields of inquiry. This presentation will discuss the accuracy and reliability of osteometric data obtained from digitally rendered models, as well as the clarity and level of detail attained. Such qualifying standards are essential if practitioners are to reliably assess pathology and taphonomic alteration to the specimens from which the scans are modeled. The suitability of each of the …

Age And Inclusivity In Umm An-Nar Communal Tombs From Southeastern Arabia, Lesley A. Gregoricka, Jaime M. Ullinger, Christian Berends, Alyssa Bolster, Brittany Clark, Hannah Jeanlouis, Urvi Kaul, Rachael Orkin

Year 2: AABA 2022 – Denver, CO

Umm an-Nar (2700-2000 BCE) tombs in the United Arab Emirates contained the commingled remains of hundreds of individuals interred across multiple generations. Archaeologists commonly reference tomb demographics as being inclusive of all ages, but this assumption is based on a handful of studies that rarely distinguish age categories beyond “subadult” or “adult.” An undergraduate research training program sought to examine age distributions – and thus inclusivity in tomb membership – in greater detail, with a particular focus on fetal and older adult age categories.

A combination of traditional and novel aging techniques were applied to bones from tombs Unar 1 …

Analyzing The Prevalence And Severity Of Cribra Orbitalia In Bronze Age Arabia, Urvi Kaul, Brittany Clark, Lesley A. Gregoricka, Jaime M. Ullinger

Year 2: AABA 2022 – Denver, CO

Background: The Umm an-Nar period (ca. 2700-2000 BCE) in southeastern Arabia was marked by the intensification of oasis agriculture and a corresponding shift to sedentism. Cribra orbitalia lesions from tombs Unar 1 and Unar 2 (Emirate of Ras al-Khaimah, UAE) were observed for rates of nonspecific stress during this period of transition. We hypothesized that due to increased reliance on agriculture beginning around 2200 BCE, Unar 1 individuals would have a higher prevalence of active cribra orbitalia.

Methods: Given the commingled and fragmentary nature of these collections, we first scored percentage of orbit present in 25% increments. Scorable orbits (defined …

A Transition From Tradition: Employing Ta3 And Traditional Age & Sex Estimation Methods To Study Paleodemography In Umm An-Nar Arabia, Alyssa Bolster, Hannah Jeanlouis, Lesley A. Gregoricka, Jaime M. Ullinger

Year 2: AABA 2022 – Denver, CO

Background: Transition Analysis 3 (TA3) has enormous potential for the study of commingled skeletal material. Previous demographic analyses on commingled remains from Umm an-Nar (2700-2000 BCE) tombs Unar 1 and Unar 2 at the site of Shimal (Ras al-Khaimah, UAE) placed the majority of individuals in a generalized “adult” category using dental eruption. We hypothesized that we would identify more older adults (50+) in both tombs using TA3, and that more would be found in Unar 2, prior to the intensification of agriculture and regional aridification.

Methods: Commingled and fragmentary skeletal fragments (pubic symphyses (n=51), humeri (n=85), femora (n=194)) were …

Estimating Age From Fetal And Young Nonadults From Basilar Portions At Umm An-Nar Tombs From The Uae, Rachael Orkin, Christian Berends, Lesley A. Gregoricka, Jaime M. Ullinger

Year 2: AABA 2022 – Denver, CO

Background: The Umm an-Nar period (2700-2000 BCE) was a time of significant change in southeastern Arabia, prompted by agricultural shifts and seen in shifting social and mortuary practices. Communal tombs Unar 1 and Unar 2 from the Emirate of Ras al-Khaimah (United Arab Emirates), which date to the end of the third millennium BCE, contained commingled, cremated, and fragmented skeletons, a common mortuary pattern in this period.

Methods: Unfused basilar portions of nonadult occipital bones were examined to assess tomb membership and inclusion of young individuals. Three methods were used to analyze age, and measurements taken included sagittal length and …

Exploring The Relationship Between Nutrition And Cribra Orbitalia: The Comparison Of Dietary Stable Isotope Comparisons Of Juveniles From Kuelap, Peru, Lissette S. Osorio

Honors Undergraduate Theses

A juvenile’s dependency on their caregiver is significant to the overall development of nutritionally related pathological lesions. However, not all skeletal pathology is caused by nutritional stress; despite anemia being the usual inferred cause, the origin of Cribra Orbitalia (CO) – lesions on the orbital roofs of the cranium– is undetermined. The purpose of this research is to compare the reconstructed diets of juveniles with and without CO and explore connections to dietary patterns (inferred from stable isotope ratios of carbon and nitrogen). Rib bone samples of 79 juveniles with and without CO were sampled from the Kuelap archaeological site …

‘Loob’ And ‘Labas’: Spatial Constructions Of Safety And Risk Amid The Covid-19 Pandemic In The Philippines, Gideon Lasco, Michael L. Tan, Vincen Gregory Yu

Development Studies Faculty Publications

This article argues that local constructions of risky and safe spaces, as articulated by the notions ‘loob’ (inside) and ‘labas’ (outside), informed popular and political responses to the COVID-19 pandemic in the Philippines, leading to an overemphasis on staying at home and, conversely, a general avoidance or fear of outdoor spaces that was at times reinforced by public health authorities. Practices and policies related to the pandemic response rendered this binary opposition between ‘loob’ and ‘labas’ visible, from regulations concerning the use of personal protective equipment to restrictions of access to outdoor spaces. While this emergent …

Utilizing Geographic Information Systems To Explore The Mortuary Landscape At Kuelap, Peru, Hannah Haynes

Electronic Theses and Dissertations, 2020-2023

The placement of the dead is important for considering social memory, a source of collective knowledge and experiences that shapes social group identity. Mortuary placement is one form of ritual action that communities undertake to remember the dead. This allows anthropologists to ask questions about how humans engaged socially with each other and the landscape. This thesis utilizes an innovative methodological approach combining geographic information systems (GIS) and stable carbon and nitrogen isotope analysis to investigate mortuary variation and social identity within the Late Intermediate Period site (A.D. 800 – 1535) Kuelap in the northern Peruvian Andes. Spatial, demographic, and …

Analyzing Cut Mark Characteristics On Bone From Chopping/Hacking Tools: Implications For Forensic Analysis, Kelly Mcgehee

Electronic Theses and Dissertations, 2020-2023

Sharp force trauma (SFT) is a mechanism of traumatic injury in which a tool with a pointed or slanted edge impacts the skin and/or bone, producing a penetrating cut mark. Current assessment of forensic and bioarchaeological contexts typically focuses on evaluating and interpreting traumatic injuries to bone due to cutting and stabbing using small, bladed tools, primarily knives and saws. Minimal research focuses on the damage inflicted by a larger class of chopping/hacking tools. Therefore, the purpose of this research was to experimentally evaluate and analyze macroscopic characteristics of chopping/hacking trauma inflicted on pig bones (Sus scrofa domesticus) to determine …

The Naming Of Homo Bodoensis By Roksandic And Colleagues Does Not Resolve Issues Surrounding Middle Pleistocene Human Evolution, Eric Delson, Chris Stringer

Publications and Research

Roksandic et al. (2022) proposed the new species name Homo bodoensis as a replacement name for Homo rhodesiensis Woodward, 1921, because they felt it was poorly and variably defined and was linked to sociopolitical baggage. However, the International Code of Zoological Nomenclature includes regulations on how and when such name changes are allowed, and Roksandic et al.'s arguments meet none of these requirements. It is not permitted to change a name solely because of variable (or erroneous) later use once it has been originally defined correctly, nor can a name be modified because it is offensive to one or more …

We Can Still Feed Ourselves: Food Sovereignty, Aid, Sickness, And Health In Eastern Kentucky, Annie Koempel

Theses and Dissertations--Anthropology

Over forty percent of eastern Kentucky residents are classified as obese. From a biomedical perspective, obesity is linked to a range of chronic diseases, including heart disease, diabetes, and high blood pressure and is caused by particular lifestyle behaviors that lead to an increase in calorie consumption and decrease in calorie expenditure. However, these links – individual behavior leads to obesity which leads to chronic disease - do not take into account a wide range of personal, social, environmental, political, and economic conditions. In addition to the assumptions of what it means to become and be obese, Kentucky is regularly …

National Barriers Impeding The Implementation Of Nagpra: Suggestions From A Small Institution, Zoe Milburn

Honors Program Theses

This thesis focuses on the impact and unrealized potentials of NAGPRA for Indigenous Americans and professional archaeologists following the first thirty years of the law’s existence. After providing some necessary background on the NAGPRA legislation and the context of the law’s passage, I examine these issues through three distinct methods. The first method focuses on a review of published Indigenous and archaeological literature to identify changes in sentiment around the law as well as to identify known hurdles within the process. The second revolves around my experience preparing a NAGPRA inventory for the Rollins College Archaeology Lab. Specifically, I reflect …

Anthropological Responses To Covid-19 In The Philippines, Gideon Lasco

Development Studies Faculty Publications

This article reflects on the roles anthropologists have played in responding to the COVID-19 pandemic in the Philippines, and identifies the challenges – from the methodological to the political – they faced in fulfilling these roles. Drawing on the author's personal and professional experiences in the country, as well as on interviews with other anthropologists, this article identifies three major roles for anthropologists: conducting ethnographic research; bearing witness to the pandemic through first-person accounts; and engaging various publics. All these activities have contributed to a greater recognition of the role of the social sciences in health crises, even as anthropologists …

The Effects Humidity & Temperature Has On Dna Contamination During Storage, Samantha L. Ramey

Graduate Student Theses, Dissertations, & Professional Papers

Studies have been conducted on DNA cross-contamination throughout the criminal investigation process in order to evaluation the possibility that DNA from one sample could potentially influence the outcome of another. However, no published studies have examined the potential for contamination during the storage of genetic evidence after samples have been taken from crime scenes or suspects. This study is a continuation of a preliminary project, which examined storage drying time in relation to cross-contamination. The current study tested temperature and humidity for the potential of cross-contamination during storage prior to extraction. Prior to storage, 50 μl of male saliva was …

Y-Chromosome Dna Extraction From Post-Cranial Skeletal Elements, Mykala D. Ward

Graduate Student Theses, Dissertations, & Professional Papers

The use of DNA in forensic science has become an integral tool for victim and perpetrator identifications, missing person’s cases, paternity testing, etc. A major use of DNA is in the identification of unknown deceased individuals. With a reported number of individuals well over 8,000 in the United States, improved methods to accurately collect and analyze DNA from modern human bone are needed.

This project took the preliminary steps to improve DNA sampling and extraction methods by analyzing the Y-chromosome DNA yield from the two bone types. While both types are composed of the same materials, cortical bone is the …

Assessing Stress Biomarkers As Embodied Identity In Kentucky’S Green River Archaic, Anna-Marie Casserly

Theses and Dissertations--Anthropology

The primary goal of this bioarchaeology dissertation research is to investigate the relationship between evidence of social identity and indicators of biological stress in the Green River region of Kentucky during the Late Archaic period (5,000-3,000 BP). Utilizing a biocultural perspective, I examine the ways that aspects of identity and social organization are embodied through the experience of biological stress. This research explores how social differences influence the patterning of osteological stress markers in an Archaic population while problematizing categories of difference that are often naturalized in bioarchaeology, such as gender or age cohorts. In so doing, it contributes to …

Morphometric Ancestral Analysis Of Infraorbital Foramen And Maxillo-Facial Landmarks Of Adult North American Skulls Using X-Ray And Computed Tomography Scans, Anna-Marie Lynn David

Graduate Student Theses, Dissertations, & Professional Papers

Skeletal remains provide a variety of information about a species population and the sub populations within that species. The infraorbital foramen has previously been used to understand dietary niches, paleoecology, the nervous system, and the effect of the nervous system on other bone functions in the facial region in humans and other mammals. In medicine, the precise location of the infraorbital foramen has been studied to aid and guide maxillo-facial procedures and surgeries. In this research project, the null hypothesis states that the placement and location of the infraorbital foramen in relation to other facial landmarks were the same between …
