Intra-Skeletal Variation In Stable Isotopes Through Non-Destructive Approaches: Applications Of The Patterns Of Skeletal Remodeling To Biological Anthropology, Armando Anzellini

Doctoral Dissertations

Stable isotope analysis is a well-established method in biological anthropology used to deliver data on residence, diet, and life history. Samples for these analyses are often collected from the diaphyses of long bones with an assumption of an expected rate of turnover between five and ten years, depending on the skeletal element. However, the biological foundations of this assumption are still uncertain, especially concerning the intra-skeletal and intra-element variation of isotopic signatures that may relate to patterns of remodeling. Exploring these gaps in intra-element isotopic variation requires fine-grained work using multiple bones from multiple individuals, but such work is limited …

Morbidity, Mortality, And Marginalization: An Intersectional Investigation Of Respiratory Stress And Differential Frailty In Industrial-Era England, Derek A. Boyd

Doctoral Dissertations

Respiratory disease affects more than one billion people today, particularly in urbanizing areas of low- and middle-income countries due to overcrowding, air pollution, poor sanitation, and differential access to life-sustaining resources. We can look to the past to understand the social, economic, and environmental factors that influence respiratory disease burden among urban dwellers because conditions in the urbanizing areas of antiquity mimic those observed in lower- and middle-income countries today. This study explored the impact of classism, sexism, and regional inequalities on respiratory disease burden among urban dwellers with differing levels of social and economic marginalization in England during the …

Sphenoidal Sinuses And Spherical Harmonics: Variation And Covariation Of The Most Morphologically Diverse And Least Understood Paranasal Sinus, Katharine Grace Josephine Ryan

Doctoral Dissertations

Understanding the shape variation of the human sphenoidal sinus is important to several areas of research. This includes clinical investigation (sinus pathology and safe endoscopic endonasal surgical practice) and paranasal sinus evolution (for which there is still no consensus). Yet, the sphenoidal sinus has high morphological variation, prohibiting its quantification through traditional geometric morphometric landmarking methods. The sphenoid body, and thus also the sinus contained within, is located directly at the developmental center of the basicranium in humans, where the three cranial fossae meet at the midline, and adjacent to the three synchondroses which are the sites of cranial base …

A Study Comparing “Better Body Bags” Versus Standard White Body Bags To Estimate Relative Preservation Of Human Genomic And Morphological Information, Serena A. Thariath

Masters Theses

In disaster scenarios, identification of the dead usually is delayed until after help is given to the living. During delays in recovery and transport of deceased individuals, decomposition of soft tissues will occur at a fast rate if individuals are not refrigerated. The Better Body Bag, or BBB, was designed for the International Committee of the Red Cross (ICRC) with features such as a vacuum seal, reflective coating, and absorbent pad to help delay the onset of decomposition that could render someone unidentifiable. In this study, the BBB was tested to determine if the individuals placed within a BBB yielded …

Primate Olfaction: A Phylogenetic Analysis Of Cribriform Plate Morphology, Amber Cooper

Anthropology Undergraduate Honors Theses

Decreased olfaction, or smell, is a diagnostic characteristic of primates. Despite this, olfaction remains important for diet and social behaviors in primates. To assess how morphological changes impact olfactory-based behaviors between the two major clades of primates, Strepsirrhini and Haplorrhini, this study examined the surface area of the cribriform plate, the bony interface between the brain and nasal cavity. Previous work has found several functional associations between cribriform plate morphology and species diet/ ecology, making this structure possibly more reflective of a species reliance on olfaction in its environment. Primate social structure, such as average group size, mating system, and …

Secular Change In Croatian Male Crania: 1812-1973, Ileana Ilas

Masters Theses

The study of secular change is the study of changes that have taken place in the human body during recent centuries. Although changes that affect populations are generally understood to occur over many centuries and millennia, anthropological studies have shown that population changes have occurred in the last two centuries, over a relatively small time period comprising a mere two hundred years. Biological anthropologists in particular are interested in how the human skeleton has changed in recent history, whether in the limbs, the torso, or the cranium. Changes have been observed in all areas of the skeleton, and these changes …

Body Size Interactions With Pubic Symphysis Age-At-Death Estimation: A Critical Analysis Of Senescence Of The Pubic Symphysis Components, Elizabeth A. Ronald

Masters Theses

Biological anthropologists struggle with accuracy and precision during age-at-death estimation when attempting to correlate biological age with chronological age, especially in older adults. Research has shown that intrinsic and extrinsic factors can cause this discrepancy. Anthropologists have recently found that body size may affect age-at-death estimation, with larger individuals being more commonly overaged and smaller individuals being underaged (Merritt, 2019; Wescott and Drew, 2015). This study elaborates on previous work in three ways. First, by applying Hartnett’s (2010) pubic symphysis phase method as the age-at-death estimation method used, which has not been assessed for body size interactions and is likely …

Ischiopubic Index: A Metric Approach To Estimating Sex In The Pelvic Region, Tripoli G. Mulvihill

Chancellor’s Honors Program Projects

No abstract provided.

Legs And Hills, Aidan Attema

Electronic Thesis and Dissertation Repository

Relatively longer leg length is a feature of the genus Homo that is often argued to have evolved due to selective pressures from a greater reliance on endurance running. Within the genus Homo, however, Neanderthals had relatively short legs with shorter tibiae – a characteristic that has been hypothesized to be a hindrance for running yet advantageous for locomoting on sloped terrains. This thesis tests three hypotheses relating to lower limb proportions and running performance: does morphological variability correspond with a) speed on flat and uphill terrain during a workout completed by cross-country athletes, or b) athletic performance during …

A Bioarchaeological Investigation Of The Courtney-Anderson Cemetery, Lauren Scott

Master's Theses

Located in Perry County, Mississippi, the Anderson Family Cemetery represents an abandoned turn-of-the-century Piney Woods cemetery. The cemetery is located on land once owned by the Courtney and Anderson families, who farmed the area until it was taken under eminent domain by the United States government in 1942. The purpose of this thesis is to present three osteobiographies created from human remains and material culture recovered from three graves excavated from within the cemetery in 2022 to explore the lifeways of rural Piney Woods families of Mississippi at the turn-of-the-century.

Among the graves explored, one did not contain evidence of …

An Analysis Of Mincer's Method And Ut-Age, Sarah Hartman

Masters Theses

Third molars have the most developmental variation of all human dentition, yet Mincer’s method and the computer program UT-Age use third molars to estimate the age of migrants crossing the U.S. border. Most migrants subjected to dental exams are classified as Hispanic. However, the term and reference samples used to estimate age do not account for the possible population variation that the term “Hispanic” can encompass. Additionally, third molar reference samples do not address the possible influence of impaction on third molar development. The objective of this study is to assess the effects of various sources of third molar variation …

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 …

Curvilinear Fractures In Burned Remains: An Assessment Of The Relationship Between Fracture Convexity And Fire Directionality, Kimber G. Cheek

Masters Theses

Burned remains present a challenge for forensic anthropologists due to the variable nature of fires, the unique way fires impact remains, and the impact of heat changes on the analysis of the remains. A topic of extensive study is the fracture patterns seen in burned remains. Curvilinear fractures are one type of fracture that was originally discussed in the context of studying the preburned state of remains (Baby, 1954; Binford, 1963; Buikstra and Swegle, 1989). These fractures are thought to be created through the kinetic energy generated as muscles shrink and pull on the periosteum, fracturing the bone below (Symes …

Transforming The Dead: The Taphonomy And Ritual Economy Of Funerary Bundles On The Pre-Hispanic Central Coast Of Peru (1000-1532 Ce), Joanna Motley

Electronic Thesis and Dissertation Repository

Death is not only the cessation of life; it is a social transformation. This dissertation investigates funerary practices that facilitated that transformation on the pre-Hispanic central coast of Peru from ca. 1000 - 1532 CE, a time of local consolidation of power after the dissolution of the Wari Empire (600-1100 CE), through to the expansion of the Inca Empire (1450 – 1532 CE). This work focuses on the practices of two archaeological cultures on the central coast of Peru: the Ychsma and the Chancay. Ritual economy, with its integration of agency and political economy, is used as a theoretical framework …

Diet And Nutrition Of Lemurs In The Lean Season, Santiago Cassalett

Dissertations, Theses, and Capstone Projects

Animals must navigate complex food and nutrient environments that are constantly in flux to obtain the macro and micronutrients necessary for their growth, reproduction, and survival. The nutritional needs of animals also vary over the life course, further complicating the search for adequate foods and the nutrients within them. The hypervariable and unpredictable environment of Madagascar creates a complex nutrient landscape for lemurs in particular because they are subject to large fluctuations in food availability. These fluctuations are thought to create extreme periods of nutritional stress during the dry season (known as the lean season) for lemurs. In response, lemurs …

Genetic Impacts Of Deforestation On Mouse Lemurs, Darice Westphal

Dissertations, Theses, and Capstone Projects

The impact of deforestation on the genetic structure of mouse lemurs is poorly understood. In this project, I assess deforestation of Madagascar’s terrestrial protected regions, quantify genomic wide genetic variation in two sympatric mouse lemurs, and evaluate the role of landscape structure in genetic relatedness patterns within two sympatric mouse lemur species. Overall deforestation rates across the 98 terrestrial protected areas in Madagascar are increasing, resulting in an average annual deforestation rate of 0.68% per year, with approximately 10,600 km² lost between 2000 and 2019. In a comparison of relatedness patterns between the sympatric gray mouse lemur (Microcebus …

Dental Health In The Aqllakuna From Farfán (Peru): A New Perspective On An Inca Female Institution (Ca. 1470-1532 A.D.) Using Micro-Ct And Histological Analysis, Émy Roberge

Electronic Thesis and Dissertation Repository

This research aims to explore the lifeways of an underrepresented subgroup of females while reducing the use of destructive methods in bioarchaeology. The excavation of Farfán on the North Coast of Peru revealed a rare aqlla cemetery from the Late Horizon (1470-1532 A.D.). The aqlla was an Inca religious institution where young females were sequestered to brew chicha and weave in their aqllawasi. According to ethnohistorical sources, these “Chosen Women” were expected to represent a homogenous and advantaged subset of the population. This hypothesis is assessed by comparing their dental lesions to the general population using macroscopy, micro-CT, and …

Health-Related Caretaking In An Institutionalized Setting: Applying The Index Of Care To Burial 1 From The Mid-19th To Early-20th Century Mississippi State Asylum, Jackson, Ms., Darcie Badon

Theses and Dissertations

This project employs a modified version of the Bioarchaeology of Care (BoC) in an analysis of Burial 1 from the Mississippi State Asylum, Jackson, MS. Burial 1 is a skeletal individual recovered from the historic MSA cemetery. Notably, Burial 1 exhibits recidivistic cranial trauma in the form of cranial depression fractures (CDFs) and significant entheseal changes in the upper extremities. However, because there is no identifying information associated with Burial 1, interpretations of the caretaking they may have received, both prior to and after institutionalization, include short- and long-term outcomes from their community and the MSA. Additionally, Burial 1’s CDFs …

Stature Estimates Of The Classic Period Maya From Chac Balam And San Juan, Ambergris Caye, Belize, Natalie Clark

Honors Theses

This thesis presents updated sex and stature estimates for ancient Maya females and males who lived in San Juan and Chac Balam in northern Ambergris Caye from approximately AD 700-900.

The regression formulae used in this study reflect a closer population affinity to the Maya compared to the equations used in the original analysis by Glassman (1995). Del Angel and Cisneros’ (2004) formulae were used when estimating stature based on a complete long bone. In Steele and Bramblett (1988), Steele and McKern (1969) and Steele (1970) regression formulae were used when estimating stature based on an incomplete humerus, femur, or …

Ageism, Eldercare, And Healthcare: An Examination Of Growing Old In Costa Rica, Akshaya Vijayasankar

Honors Theses

The world’s aging population and the Covid-19 pandemic have revealed the high level of ageism against older adults around the globe, which has resulted in an overall decreased quality of life for elders. Societies are now faced with the challenge of creating a suitable and equitable model of care to support their aging population. Despite the recent publication of the World Health Organization's Global Report on Ageism, there is still a large gap in the literature regarding ageism. This paper addresses the issues of institutional ageism in the eldercare and healthcare sector. I argue that Costa Rica serves as a …

The Abuse Of Darwinism (And Social Darwinism) For The Purposes Of Discrimination, Jessica N. Kantrowitz

Honors Student Research

Throughout most of history, people have tried to justify their discrimination against other groups of people in any way they can, especially using biology and evolutionary theories as reason. When Charles Darwin published his book “On the Origin of Species”, introducing his theory of evolution and the work and experiments he did to prove this theory, it caused many to question their previous bigoted beliefs. For some, however, Darwin’s theory of evolution, which would come to be referred to simply as Darwinism, only further proved their biases, or they could, at least, make it sound like they did. Later on, …

As a result of cultural differences, health disparities among ethnic groups in Kenya are increasing. A component of patient centered care involves the incorporation of cultural aspects of health and illness in the delivery of nursing care. Understanding cultural competence of nursing students will provide guidance on educational needs related to cultural competence.

Purpose:. The purpose of this study was to assess nursing students’ cultural competence (CC) in the areas of cultural awareness, knowledge, sensitivity, skills, encounters and desire. Nursing students’ views on caring for …

Reconstructing Bison And Mammoth Migration During The Late Pleistocene And Early Holocene Of Central Texas Using Strontium Isotopes, Joshua John Porter

Graduate Theses and Dissertations

During the Late Pleistocene (LP; past 130,000 years), over two-thirds of large mammal (>45kg) species went extinct globally. While the role of humans is hotly debated, the effect of these extinctions is growing clearer; the extinctions resulted in widespread and lasting faunal community reorganization. However, the impact of these extinctions on dietary and migratory behavior within faunal communities is unknown. Our study examines the impact of the megafaunal extinctions on the dietary and migratory behavior of surviving Bison individuals in Texas using carbon, oxygen, and strontium isotopes. Strontium isotopes are incorporated into mammalian enamel during their tooth development and …

Teaching Old Calipers New Tricks: Using Craniometrics For Ancestry Admixture Estimation Via Fuzzy Math, Kristi Carnahan

Master's Theses

Cranial measurements have been a cornerstone of physical anthropology since its formation as a discipline in the early 1900s. However, most other ancestry determination methods come with a significant epistemological issue: they differentiate individuals into discrete categories without accounting for the issue of admixture. Advances in data mining and analysis techniques can now be used to help resolve this issue through soft computing, also known as “fuzzy math”. This type of advanced computational math requires specialized knowledge in computer programming, statistics, and data analysis techniques unless one is using computer programs specially designed to run these analyses.

This project compiled …

Investigating The Mechanics And Chemistry Of Sickle Polish Development, Justin Jared Dubois

Graduate Theses and Dissertations

This series of experiments is designed to understand the development and chemistry of sickle gloss. Sickles are common in the archaeological record and have long been studied for their eponymous “sickle gloss”. There is debate as to how this gloss is formed. Five experimental sickles containing flint and novaculite blades were used to harvest high and low moisture content rye and common fescue and associated field weeds. The differences in the development of sickle gloss were examined. High moisture content plants create thick, smooth fields of polish with undulating, billowing margins at a higher developmental speed. Low moisture content plants …

Evaluating Cremation In Umm An-Nar Period Mortuary Practices Using Laser-Induced Breakdown Spectroscopy (Libs), Malena Butler

Anthropology Undergraduate Senior Theses

Chemical changes in bone composition that occur during the process of cremation have begun to be explored alongside corresponding macroscopic changes to bone color using a variety of analytical instrumentation. This research employed a lesser-utilized method, Laser-Induced Breakdown Spectroscopy (LIBS), alongside Munsell Color Charts to assess elemental changes that may occur in archaeological bone at varying cremation temperatures. It was hypothesized that differences in color would be indicative of different chemical compositions present in bone, despite previous evidence for at least some diagenetic change. Distal humeri from Umm an-Nar (2700-2000 BCE) period tombs Unar 1 (n=31) and Unar 2 (n=28) …

Quantification Of Dental Fissures Through Occlusal Topography Analysis, Duru Erkan

Biological Sciences Undergraduate Honors Theses

Narrow, deep, and elaborate dental fissures are widely believed to increase the predisposition of enamel to develop carious lesions as these surfaces are thought to be ideal for cariogenic bacteria to adhere to. Therefore, dentists prescribe sealants as a preventative measure for patients with such fissures to avoid tooth decay. Yet to date, there is no objective data supporting the notion that fissure morphology actually affects caries susceptibility, nor is there a quantifiable, clinically practical method to characterize fissure patterns expected to increase risk of caries disease.

In this study, three new methods to quantitatively characterize fissure pattern in mandibular …

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 …

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 …

Moral Distress, Burnout, And Moral Injury In Healthcare Professionals, Sophia Gibson

Anthropology Undergraduate Honors Theses

For doctors and other health care professionals, experiences of care too often involve burnout and moral distress. Making both visible to begin addressing them takes up the main concern of my thesis. Burnout and moral distress swallow a life. Suddenly you aren’t going on that shopping trip with friends, you can forget about going to that movie or play. You are too tired to drag yourself out of bed, instead getting caught in a cycle of sleep and work with no time for a break or even to process what happened last shift. Who’s going to have a nice relaxing …
