The Politics Of The Black Womb: How Education And Power Reinforce The U.S. Black Maternal Health Crisis, Foluke Akinkunmi

Honors Scholar Theses

This study investigates the alarming maternal mortality rates among Black women in the U.S. today first by exploring the historical exploitation of Black maternal bodies during enslavement and with the rise of professionalized gynecology. It challenges the narrative that attributes these outcomes to individual choices or supposedly inherent biological factors, arguing instead that the devaluing of Black women’s well-being and authoritative knowledge have been constructed along with the United States itself. To advance a constructive response, the paper analyzes curriculum competencies for obstetric and midwifery healthcare providers, surveys of Black women's birthing experiences in the previous 20 years, and interviews …

Male And Female Contributions To Sexual Dimorphism, Catherine L.W. Clayton

Graduate Theses and Dissertations

Since Darwin, the evolution of sexual dimorphism connects to different evolutionary mechanisms reflecting both natural selection and sexual selection. In primates, body size dimorphism has been attributed to multiple factors, including sexual selection, fecundity selection, ecological selection, and other factors. In contrast, canine tooth size dimorphism has been primarily associated with sexual selection in males with minor change in females, with other factors playing only a secondary role. This suggests that the degree to which body size dimorphism and canine size dimorphism covary, controlling for phylogeny, should reflect the strength of sexual selection. Conversely, the magnitude of divergence between the …

Primates Shed Light On Glowing Mammals – Adaptation Or Epiphenomenon?, Juliana Hicks

Anthropology

Fluorescence is the ability of chemicals and materials to give off visible or invisible light after absorbing radiation such as ultraviolet light. Fluorescence has been documented in several mammalian families, yet Primates, as an order, have received limited attention in this regard. Within Primates, the suborder Strepsirrhini has been particularly overlooked. Strepsirrhines are compelling subjects due to their retention of primitive mammalian characteristics, representing a significant knowledge gap with respect to the occurrence of fluorescing pelage within the class Mammalia. To address this gap, we investigated the presence and absence of fluorescence in the pelage of preserved museum strepsirrhine specimens …

Accuracy Of Angular Displacement Measurements Using Imu, Aidan Mills

Anthropology

As a part of a larger group, this research focused on gathering data from accelerometers to gather further knowledge on how these devices could be used in further experiments. Using the Sparkfun Artemis accelerometer, angular displacement was isolated and tested to understand the parameters and abilities of the device. Simple tests were run moving the device through 90 degree angular changes. The data collected by the accelerometer was then analyzed using code written specifically to graph angular changes. The data was run through a low and a high pass filter to account for any drift experienced during the tests. An …

Parkinson’S Disease Pathophysiology And Comparative Analysis Of The Efficacy Between Subthalamic Nucleus And Globus Pallidus Interna Deep Brain Stimulation: A Student’S Perspective, Peter C. Solimando Ii

Anthropology

Parkinson’s Disease (PD) is becoming an increasingly common neurodegenerative disease across the world, presenting with both debilitating motor and non-motor symptoms that progressively worsen throughout the course of the disease. Prominent motor symptoms include tremors, bradykinesia, muscle rigidity, and postural/gait instabilities, while common non-motor symptoms include fatigue, pain, autonomic dysfunction (i.e., bowel and bladder dysfunction), mood disorders, and dementia. The advent of modern medical management of PD has introduced several different medications, the most popular being levodopa, that have shown success in reducing the severity of motor symptoms, particularly in the early stages of the disease. Throughout disease progression, however, …

Accuracy Of Balance Assessment Metrics Using Wearable Sensors, Brandon Sirof

Anthropology

Balance is a critical part of remaining healthy at all ages. Poor balance can lead to life-changing injury. Balance is typically assessed in a lab using a force-platform (FP), by comparing horizontal movements of the center of mass during trials with eyes open and eyes closed. The goal of this study is to evaluate whether inertial measurement units (IMUs) can be used to accurately measure balance. Simultaneous FP and IMU data were collected for 1 subject for 45s trials with eyes open (EO) and eyes closed (EC). We evaluate whether IMU and FP metrics for COM movement (max accel and …

Using Wearable Sensors For Gait Analysis: Measurement Accuracy For Linear Measurements, Evan Block

Anthropology

Measurement and analysis of human movement are necessary in a broad range of clinical, sports performance, and artistic applications. Historically, motion data were typically collected using optical motion capture systems. However, these systems are expensive and can only be used in lab spaces, which limits the range and speeds of human behavior. More recently, inexpensive, wearable sensors called Inertial Measurement Units (IMUs) have enabled motion measurement in natural settings, but these systems require validation before use. In this study, we evaluate measurement accuracy for linear displacements obtained using Sparkfun OpenLog Artemis IMUs. We conducted a series of tests, moving the …

Comparison Of Femoral Head Loading In Chimpanzees And Humans, Kyra Kalinovsky

Anthropology

Chimpanzees are the closest living relatives of humans, despite this, the species do have very different loading on the epiphysis of the proximal head of the femur. The difference in loading is primarily due to a difference in locomotion. These differences affect the properties of subchondral and trabecular bone properties in the femoral head. Previous studies have shown that chimpanzees have thick and concave trabeculae that create a dense bone structure (Georgiou et al., 2018). These are found mostly on the inferior and central part of the femoral head. In humans, the structure of the trabecular bone volume is less …

Interobserver Agreement Of Human Osteological Analysis On The Szeged, Hungary Skeletal Collection, Alleyia Bailey

All Theses

Biological anthropologists develop human skeletal biological profiles to identify skeletal remains and build demographic knowledge of past and modern peoples. Biological anthropologists estimate age-at-death, sex, stature, ancestry, and the presence of injury or pathology to develop biological profiles. While biological profiles are at the basis of the work anthropologists perform, there is a lack of research concerning the reproducibility and interobserver agreement rates of the methods used to create biological profiles. Due to the risk of variability stemming from the education, training, and experience of observers, along with variation that can arise from population affinity, examining the interobserver agreement rates …

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 …

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 …

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 …

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 …

Comparing Urban And Rural Mississippi Residents’ Health Literacy Of Sexually Transmitted Infections, Leah Tucker

Honors Theses

Health literacy is an individual’s ability to understand medical information to make decisions regarding their health, and it has become an important topic of discussion in the medical field. This is because people with low health literacy are more likely to be in poor health. There have been several programs aimed at improving health literacy across the US, but health literacy varies geographically. Typically, urban areas have higher health literacy rates than rural areas since rural areas have less access to health resources and health care. Almost 80% of Mississippi’s counties are considered rural, and Mississippi has some of the …

Smoking And Oral Health In The Tipu Maya: A Study Of Nicotine In Dental Calculus, Emily Byrd

Honors Theses

Tobacco smoking was a deeply rooted tradition in Maya society, often associated with ritual and daily life, and may have contributed to patterns of dental health. However, despite its cultural significance, direct biological evidence of tobacco use in ancient populations is rare. This study addresses that gap by analyzing nicotine residues preserved in dental calculus from the Tipu Maya, offering new insight into both cultural practices and potential health impacts.

Mass spectrometry identified molecular peaks corresponding to nicotine and its degradation products within the calculus samples.  Analysis revealed that over two-thirds of the individuals tested positive for nicotine, supporting the …

Sex Differences In Adult Frailty At The Late-Terminal Classic (C. 750-1000 Ce) Maya Site Of Lower Dover, Rose Rioux

Honors Thesis

While it has been suggested that the compounded effects of population growth and climatic pressures over the Classic period (c. 300-1000 CE) led to a health crisis among the Maya, there is no current knowledge of whether there were significant sex differences in risks of mortality and frailty associated with metabolic stressors. This research assesses sex differences in frailty and mortality of adults (n=52) from the medium-sized Maya polity of Lower Dover in the upper Belize River Valley from the Late Preclassic (c. 300 BCE-150 CE) to Terminal Classic (c. 750-1000 CE). Osteological methods of estimating age and sex were …

Characterizing The Nutrition-Gut Microbiome-Host Physiology Axis To Examine Flexibility In A Fruit-Specialist Primate, Nina Beeby

Dissertations, Theses, and Capstone Projects

Nutrition and, increasingly, microbiota are recognized in shaping all aspects of animal behavioral ecology and physiology. Since diet and nutrition shape not only animal physiology but also gut microbiota, and these microbiota serve as suppliers of and competitors to host nutrition, this raises questions of how these complex nutritional and microbial environments synergistically affect animal physiology. Examining this nutrition-gut microbiome-host physiology axis has immense potential to unveil how these intricate relationships contribute to animals’ responses to environmental change at multiple scales. Most of what we know about primate responses to environmental change is based upon studies examining one or few …

Pass It Along: Learning About Health Inequities Through Project-Based Learning And A Student-Developed Workshop, Marcy S. Ekanayake-Weber, Deanna Cunha, Kristi L. Fung, Sydney Macgregor, Nicole Ribeiro, Nicholas Smith

International Journal of Transformative Teaching and Learning in Higher Education

People in marginalized communities experience reduced quality of healthcare due to complex interactions between implicit bias, stereotypes, and structural inequities, but future healthcare providers remain unprepared to confront these problems. To address the issue of health inequities in health sciences education, a project-based learning seminar for undergraduates called “Biology of Inequity” was developed and offered by the Department of Anthropology at [redacted] University in Spring semester 2022. Following the project-based learning (PBL) framework, the course was extremely interactive, culminating in a project where students were asked to “materially improve health inequalities out in the real world.” The students responded by …
