The Role Of Culture In Sustainable Communities: The Case Of Rapa Nui (Easter Island, Chile), Pamela A. Mischen, Carl P. Lipo

Anthropology Datasets

We explore how the combination of cultural heritage and present-day cultural affili- ations influences the construction of the concept of sustainability at the scale of the community using the case study of Rapa Nui (Easter Island, Chile). We argue that overlapping affiliations—expressed through administrative culture, organizational culture, and professional culture—influence the views held by governance leaders. Furthermore, the role of cultural heritage must be considered in efforts to change and perpetuate sustainability-related behaviors within a community. Using archeo- logical and historical evidence from the pre-contact and historical record of Rapa Nui, we discuss how cultural heritage evolved endogenously in response …

The Genetic Links Between Archaic And Modern Humans, Maria J. Orellana Rosales

Thinking Matters Symposium

Our modern physiology is the mixture of many archaic humans that once roamed our planet. The evidence of these archaic humans is still present in our DNA. This poster reviews how our understanding of ancient human genetics has drastically changed due to advances in molecular genetics. Neanderthal and Denisovan remains have been sequenced for nuclear and mitochondrial DNA. Neanderthal and Denisovan genetic ancestry have been identified by genomic studies in modern human populations across Eurasia and Pacific Island regions. Studies have shown a gene flow of 4±1% from Neanderthals to present-day Eurasians. Whereas, Papuan and Melanesian individuals share 4±0.7% more …

Embodied Injustices: Covid-19, Race, And Epigenetics, Maria Encinosa

Showcase of Osprey Advancements in Research and Scholarship (SOARS)

Digital Projects Showcase Exhibitor Award Although historical and even modern accounts of race assume significant biological differences between racial groups, race has little biological meaning. Nonetheless, the social construct of race has real consequences. Racial identity defines boundaries of community and impacts the experiences of individuals, including how people live and die during a pandemic. COVID-19 has disproportionately affected minority communities in the United States, triggering many explanations for racial disparities in health. Through an analysis of sources spanning from popular media to traditional academic journals, I analyze the potential for epigenetic research to serve as a missing link that …

Dental Disparities: A Quantitative & Regional Analysis Of Male Oral Health In The United States, Hannah Merritt, Gordon Rakita

Showcase of Osprey Advancements in Research and Scholarship (SOARS)

Project of Merit Winner

Multiple factors contribute to the oral health of male individuals in the United States, including economic, regional, and gender disparities. My study compares health care coverage and poverty rates to indicators of oral health status and dental care access such as percentage of tooth lost, number of dental visits, and oral health services at federally qualified health centers. This oral health data is drawn from the Center for Disease Control and Prevention across all fifty states in the year 2018 and from the United States Census. By examining this data, I will be able to answer …

"The Face Of The Agency": Interviews With Death Investigators In South Louisiana, Natalie H. King

LSU Master's Theses

According to the American Board of Medicolegal Death Investigators, “the role of the medicolegal death investigator is to investigate any death that falls under the jurisdiction of the medical examiner or coroner, including all suspicious, violent, unexplained and unexpected deaths” (American Board of Medicolegal Death Investigators [ABMDI], n.d.). As such, a death investigator has a job that is highly intense and stressful at a level similar to that of doctors, nurses, emergency medical technicians (EMTs), and firefighters. The majority of the literature written about death investigators focuses on procedural issues, while there seemingly is a lack of literature focused on …

The Bioarchaeology Of The Lake St. Agnes Mound (16av26) Site: Exploring Diet From Fragmentary Remains, Kenneth Tremblay

LSU Master's Theses

The Lake St. Agnes Mound (16AV26) site, located in central Louisiana, is composed of two, temporally distinct burial components; one, a Coles Creek period component, at the base of the mound (~780-880 CE), and the other, a Plaquemine subperiod component, at its apex (~1400 CE). These burials, though heavily fragmented, commingled, and representing small sample sizes, are valuable for studying the transition to agriculture in the Lower Mississippi River Valley. It is now clear that for the Coles Creek period, maize was likely only a ceremonial crop rather than a staple food source (Kidder, 1993; Listi, 2011). The reliance on …

Assessing The Validity Of The Estimation Of Population Affinity From The Maxillary Hard Palate: An Empirical Approach Using A Modern Forensic Sample, Christopher M. Goden

LSU Master's Theses

In response to Beathard and DiGangi’s (2020) call to action for empirical assessment of population affinity estimation methodology, this study investigates the validity of maxillary palate shape as an indicator of ancestral population affinity for human skeletal remains through the use of Elliptical Fourier Analysis (EFA) and Linear Discriminant Function Analysis (DFA). Further, this study also places emphasis on the expressed variation of palate shape within and between population groups exemplified by Principal Component Analysis (PCA) of EFA data.

Computed tomography scans of 180 individuals of Black, White, and Hispanic population affinities were obtained from the New Mexico Decedent Imaging …

Using The Seventh Rib Length And Depth Measurements As A Method To Estimate Ancestry And Sex In Adults, Alexandria M. Amaki

LSU Master's Theses

This study tested the correlation of dimensions of the left seventh rib (L7) to ancestry and sex in adult humans. The first hypothesis, based on Bergmann’s theory, is that Black (African-American) individuals will have smaller L7 dimensions than White individuals (Americans of primarily European descent). The second hypothesis is that males, due to sexual dimorphism, will have larger ribs than females. 299 individuals from the Hamann-Todd Skeletal Collection were used in the study, approximately evenly distributed among sex and ancestry groups. Five variables were examined, including three measurements (length, width, and width point), and two calculations (area and ratio). A …

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 …

Was Facial Width-To-Height Ratio Subject To Sexual Selection Pressures? A Life Course Approach, Carolyn R. Hodges-Simeon, Graham Albert, George B. Richardson, Timothy S. Mchale, Seth M. Weinberg, Michael Gurven, Steven J.C. Gaulin

Anthropology and Museum Studies Faculty Scholarship

Sexual selection researchers have traditionally focused on adult sex differences; however, the schedule and pattern of sex-specific ontogeny can provide insights unobtainable from an exclusive focus on adults. Recently, it has been debated whether facial width-to-height ratio (fWHR; bi-zygomatic breadth divided by midface height) is a human secondary sexual characteristic (SSC). Here, we review current evidence, then address this debate using ontogenetic evidence, which has been under-explored in fWHR research. Facial measurements were collected from 3D surface images of males and females aged 3 to 40 (Study 1; US European-descent, n = 2449), and from 2D photographs of males and …

Zoonotic Diseases: New Directions In Human–Animal Pathology, Robin Bendrey, Debra Martin

Anthropology Faculty Research

Zoonotic diseases—human diseases of animal origin—represent one of the world's greatest health challenges, both today and in the past. Since the Neolithic, zoonotic diseases have been one of the major factors shaping and influencing human adaptation. Archaeology is ideally situated to provide the long view on human–animal–pathogen relationships through combining cultural, environmental and biological datasets, yet long-term studies of linked human and animal records have often been overlooked and undertheorized. The seven papers in this special issue “Zoonotic diseases: New directions in human–animal pathology” cover a range of diseases caused by bacterial, viral, and parasitic pathogens, from case studies drawn …

Very Low Prevalence And Incidence Of Atrial Fibrillation Among Bolivian Forager-Farmers, Christopher J. Rowan, Michael A. Eskander, Edmond Seabright, Daniel Eid Rodriguez, Edhitt Cortez Linares, Raul Quispe Gutierrez, Juan Copajira Adrian, Daniel Cummings, Bret Beheim, Kirsten Tolstrup, Abinash Achrekar, Thomas Kraft, David E.

ESI Publications

Background: Atrial fibrillation is the most common arrhythmia in post-industrialized populations. Older age, hypertension, obesity, chronic inflammation, and diabetes are significant atrial fibrillation risk factors, suggesting that modern urban environments may promote atrial fibrillation.

Objective: Here we assess atrial fibrillation prevalence and incidence among tropical horticulturalists of the Bolivian Amazon with high levels of physical activity, a lean diet, and minimal coronary atherosclerosis, but also high infectious disease burden and associated inflammation.

Methods: Between 2005–2019, 1314 Tsimane aged 40–94 years (52% female) and 534 Moseten Amerindians aged 40–89 years (50% female) underwent resting 12-lead electrocardiograms to assess atrial fibrillation prevalence. …

Considerations For Post-Processing Parameters In Mixed-Method 3d Analyses: A Mesolithic Mandibular Case Study, Robert Z. Selden Jr., Lauren N. Butaric, Kersten Bergstrom, Dennis Van Gerven

CRHR: Archaeology

The production of three-dimensional (3D) digital meshes of surface and computed tomographic (CT) data has become widespread in morphometric analyses of anthropological and archaeological data. Given that processing methods are not standardized, this leaves questions regarding the comparability of processed and digitally curated 3D datasets. The goal of this study was to identify those processing parameters that result in the most consistent fit between CT-derived meshes and a 3D surface model of the same human mandible. Eight meshes, each using unique thresholding and smoothing parameters, were compared to assess whole-object deviations, deviations along curves, and deviations between specific anatomical features …

An Examination Of Sex Distributions In Umm An-Nar Tombs From Bronze Age Arabia Using The Distal Humerus, Charles Downey, Silvio Ernesto Mirabal Torres, Lesley A. Gregoricka, Jaime M. Ullinger

Year 1: AAPA 2021 – virtual

Background: Umm an-Nar (2700-2000 BCE) communal tombs from southeastern Arabia contain human skeletal remains characterized by extensive commingling and variable degrees of burning. Because of this, few bioarchaeological studies have been conducted examining the proportions of males to females in these monumental tombs. We hypothesized that increased social stratification in the late Umm an-Nar period would lead to a higher number of males interred in Umm an-Nar tombs over time.

Methods: To estimate sex, we measured four features of the distal humeri from tombs Unar 1 (2400-2200 BCE) and Unar 2 (2300-2100 BCE). Heat-induced changes to bone from cremation were …

Mni And Sex Estimation In Two Umm An-Nar Tombs From The Uae, Jaime M. Ullinger, Lesley A. Gregoricka, Chaylee Arellano, Quentin Burke, Victoria Calvin, Charlie Downey, Rachel Heil, Alyssa Mcgrath, Silvio Ernesto Mirabal Torres, Jeremy Simmons

Year 1: AAPA 2021 – virtual

Commingled tombs are often overlooked in bioarchaeological studies because of the difficult nature of analysis, despite their prevalence across the ancient world. Tombs Unar 1 (U1) and Unar 2 (U2), located in the United Arab Emirates, date to the Umm an-Nar period (2700-2000 BCE), when people witnessed shifts in mortuary practices likely reflective of broader changes in subsistence and social organization. A collaborative project that trains undergraduates in anthropological research has examined tomb membership for U1 and U2 by estimating MNI and sex. Despite early descriptions of U1 and U2 holding similar numbers of individuals, this project found that MNI …

A Tali Of Two Tombs: Calculating Mni And Bone Calcination In Commingled Remains From Two Bronze Age Tombs In The Uae, Alyssa Mcgrath, Rachel Heil, Lesley A. Gregoricka, Jaime M. Ullinger

Year 1: AAPA 2021 – virtual

Background: The Umm an-Nar period (2700-2000 BCE) is known for its dichotomy between the rise in social hierarchy during life, seen in the construction of monumental towers and emergence of oasis agriculture, and equal treatment in death, seen in the commingling of all community members within monumental tombs. Umm an-Nar tombs Unar 1 (2400-2200 BCE) and Unar 2 (2300-2100 BCE) were part of the Shimal Necropolis in the United Arab Emirates. Archaeologists initially hypothesized that these tombs each contained 400+ people, but these estimates were not based on bioarchaeological methods.

Methods: Using the talus, the landmark and zonation methods were …

Sex Estimation For Early Bronze Age Arabian Tombs Using The Temporal Bone, Victoria Calvin, Jeremy Simmons, Lesley A. Gregoricka, Jaime M. Ullinger

Year 1: AAPA 2021 – virtual

Background: The Umm an-Nar period (2700-2000 BCE) in the United Arab Emirates was marked by the appearance of settlements, oasis agriculture, and fortification towers, suggesting increasing stratification. Conversely, mortuary practices indicate equality based on commingling of community members. Based on other tombs in the region, it was hypothesized that sex ratios would not differ between tombs Unar 1 (U1; 2400-2200 BCE) and Unar 2 (U2; 2300-2100 BCE).

Methods: Sex was estimated using robusticity of the mastoid process and the lateral angle of the internal auditory meatus for the temporal bone. As cremation was part of the mortuary ritual and could …
