Sex, Energy, Well-Being And Low Testosterone: An Exploratory Survey Of U.S. Men’S Experiences On Prescription Testosterone, Alex A. Straftis, Peter B. Gray

Anthropology Faculty Research

Prescription testosterone sales in the United States have skyrocketed in the last two decades due to an aging population, direct-to-consumer advertising, and prescriber views of the benefits and risks to testosterone, among other factors. However, few studies have attempted to directly examine patient experiences on prescription testosterone therapy. The present exploratory study involved an online self-report survey of U.S. testosterone patients who were at least 21 years of age. The primary focus was on patient perspectives concerning motivations leading to the initiation of testosterone therapy and the perceived effects of treatment. Responses to open-ended questions drew upon a coding scheme …

Nutritional Assessment Of Oraons Of West Bengal: A Comparison Between Biochemical And Anthropometric Methods, Ankita Bhattacharya, Shankarashis Mukherjee, Subrata Kumar Roy

Journal Articles

Comprehensive nutritional assessment is the basis of nutritional diagnosis and necessary to identify the individual or the population at a risk of dietary deficiencies. However, there is no specific and confirmatory method to measure nutritional status. Present study tried to find out the efficacy of two nutritional assessment method (1) biochemical test like Total serum protein (TSP) and (2) anthropological measurements like body mass index (BMI) and mid-upper-arm-circumference (MUAC). Later, three methods were tested and compared for the strength of assessing the nutritional status. Study was conducted among 198 adult Oraon, 84 male, 114 female individuals of Madarihat and Falakata …

Oldowan Tool Behaviors Through Time On The Homa Peninsula, Kenya, Emma M. Finestone

Dissertations, Theses, and Capstone Projects

The adaptive significance of tool use to genus Homo is a central theme in human origins. However, what we know from the early Oldowan sites suggests that persistent technology may have begun as an opportunistic behavior with minimal investment, rather than a habitual and widespread adaptive revolution. This dissertation seeks to investigate investment in Oldowan tool production on the Homa Peninsula, Kenya, considering raw material selection, transport, and lithic production at two newly discovered Oldowan localities: Nyayanga (ca. 2.6 Ma) and Sare River (ca. 1.7 Ma).

The first section of this dissertation outlines a method that enables the comparison of …

Computed Tomography Shows High Fracture Prevalence Among Physically Active Forager-Horticulturalists With High Fertility, Jonathan Stieglitz, Benjamin C. Trumble, Horus Study Team, Caleb E. Finch, Dong Li, Matthew J. Budoff, Hillard Kaplan, Michael D. Gurven

ESI Publications

Modern humans have more fragile skeletons than other hominins, which may result from physical inactivity. Here, we test whether reproductive effort also compromises bone strength, by measuring using computed tomography thoracic vertebral bone mineral density (BMD) and fracture prevalence among physically active Tsimane forager-horticulturalists. Earlier onset of reproduction and shorter interbirth intervals are associated with reduced BMD for women. Tsimane BMD is lower versus Americans, but only for women, contrary to simple predictions relying on inactivity to explain skeletal fragility. Minimal BMD differences exist between Tsimane and American men, suggesting that systemic factors other than fertility (e.g. diet) do not …

Comparison Of Play Frequency In Four Sympatric Monkey Species In Kibale National Park, Uganda, Sara G. Lucci

Theses and Dissertations

This study describes play in red colobus (Procolobus rufomitratus), grey-cheeked mangabeys (Lophocebus albigena), black-and-white colobus (Colobus guereza), and redtail monkeys (Cercopithecus ascanius) to test Instinct-Practice Theory. Solitary locomotor play was different among the species. Rough-and-tumble play was different between male and female redtail monkeys. These results partially support Instinct-Practice Theory.

The Dynamics Of Men's Cooperation And Social Status In A Small-Scale Society, Christopher Von Rueden, Daniel Redhead, Rick O'Gorman, Hillard Kaplan, Michael Gurven

ESI Publications

We propose that networks of cooperation and allocation of social status co-emerge in human groups. We substantiate this hypothesis with one of the first longitudinal studies of cooperation in a preindustrial society, spanning 8 years. Using longitudinal social network analysis of cooperation among men, we find large effects of kinship, reciprocity and transitivity in the nomination of cooperation partners over time. Independent of these effects, we show that (i) higher-status individuals gain more cooperation partners, and (ii) individuals gain status by cooperating with individuals of higher status than themselves. We posit that human hierarchies are more egalitarian relative to other …

The Archaeology Of Mississippian Vulnerability And Resilience In The New Madrid Seismic Zone, Michelle Megan Rathgaber

Graduate Theses and Dissertations

This work examines the vulnerability and resilience of Mississippian people in the Central Mississippi Valley to the large-scale New Madrid seismic zone earthquakes of the late15th to early 16th century. This is done using the theory of eventful archaeology/anthropology to look at cultural materials both before and after an event (such as an earthquake and sand blows) to look for evidence of changes to the schema and resources on which a society relies. If changes are present, the event can be labeled as such, if there are no changes, it means that the society affected did not see the event …

How Extrinsic Mortality Affects Age At Menarche And Fertility In A 1970 British Cohort, Kimberly Marie Neagle

Boise State University Theses and Dissertations

Extrinsic mortality is the likelihood of mortality that is not conditional on reproductive effort. It does not depend on a person’s behavior and cannot be changed by altering behavior. Theoretically, extrinsic mortality plays a major role in the evolution of life history and the variation in reproductive strategies. Using life history theory as a framework, with higher extrinsic mortality cues women should speed up reproduction to maximize fitness in uncertain or risky environments, and in environments with little risk, women can allocate their energy to somatic development and in this time, accrue resources such as education and career opportunities. Thus, …

An Early Modern Human Outside Africa, Eric Delson

Publications and Research

Analysis of two fossils from a Greek cave has shed light on early hominins in Eurasia. One fossil is the earliest known specimen of Homo sapiens found outside Africa; the other is a Neanderthal who lived 40,000 years later.

Kinship Ties Across The Lifespan In Human Communities, Jeremy Koster, Dieter Lukas, David Nolin, Eleanor Power, Alexandra Alvergne, Ruth Mace, Cody T. Ross, Karen Kramer, Russell Graves, Mark Caudell, Shane Macfarlan, Eric Schniter, Robert Quinlan, Siobhan Mattison, Adam Reynolds, Chun Yi-Sim, Eric Massengill

ESI Publications

A hypothesis for the evolution of long post-reproductive lifespans in the human lineage involves asymmetries in relatedness between young immigrant females and the older females in their new groups. In these circumstances, inter-generational reproductive conflicts between younger and older females are predicted to resolve in favor of the younger females, who realize fewer inclusive fitness benefits from ceding reproduction to others. This conceptual model anticipates that immigrants to a community initially have few kin ties to others in the group, gradually showing greater relatedness to group members as they have descendants who remain with them in the group. We examine …

Probability, Populations, Phylogenetics And Hominin Speciation, Niccolo Caldararo

Human Biology Open Access Pre-Prints

A number of recent articles have appeared on the hominin Denisova fossil remains. Many of them focus on attempts to produce DNA sequences from the extracted samples. Often these project mtDNA sequences from the fossil remains of a number of Neandertal fossils and the Denisovans in an attempt to understand the evolution of Mid Pleistocene human ancestors. These papers, introduce a number of problems in the interpretation of speciation in hominins. One concerns the degradation of the ancient DNA and its interpretation as authentic genetic information. Another concerns the idea of “species” versus that of “population” and the use of …

The Humboldt Coastal Nature Center and the surrounding coastal dunes (HCNC) are man-aged as a land trust by Friends of the Dunes (FOD). FOD prioritize the restoration of dune habitats and encourages public involvement through community supported education and stewardship programs, guided nature tours, and naturalist training programs. The faculty, students, and …

Trends In Health, Stress, And Migration In The Pre-Contact Southwest United States, Alexis O'Donnell

Anthropology ETDs

The major goal of this dissertation was to examine migration and its impacts on health through use of dental morphological and paleopathological data. The case study is the Southwest United States between A.D. 1200-1400s. The second chapter, written with Corey Ragsdale, Biological Distance and the Fate of the Gallina in the American Southwest, examines where the Gallina people may have gone upon abandoning their homes in the late A.D. 1200s. We used dental data for 492 individuals and mean measure of divergence (biodistance) analysis to examine several hypotheses regarding where the Gallina went. We find that the Gallina may have …

Microdamage As A Bone Quality Component: Practical Guidelines For The Two‐Dimensional Analysis Of Linear Microcracks In Human Cortical Bone, Victoria M. Dominguez, Amanda M. Agnew

Publications and Research

Microdamage is a component of bone quality believed to play an integral role in bone health. However, comparability between existing studies is fraught with issues due to highly variable methods of sample preparation and poorly defined quantification criteria. To address these issues, this article has two aims. First, detailed methods for preparation and analysis of linear microcracks in human ribs, specifically addressing troubleshooting issues cited in previous studies, are laid out. Second, new, partially validated criteria are proposed in an effort to reduce subjective differences in microcrack counts and measures, ensuring more comparable results between studies. Revised definitions based on …

Trauma Analysis From Rapid Staircase Descension, Srinanti Bhattacharya

CURCE Annual Undergraduate Conference

This experiment was designed after the release of the Netflix show called the “The Staircase.” A true documentary, a woman’s fall down the staircase results in her death, but the investigators question whether it was an accident or murder. The woman’s husband was initially accused of murder, but after a lengthy trial and the review of additional evidence, it was ruled an accident. In the autopsy results, there was evidence of blunt force trauma (Figure 1) inconsistent with an accidental fall. Therefore this research asks what is the difference in trauma from an accidental fall versus a intentional, assisted descent?

Determination Of Intersex Humans In Human Remains, Audria Payne

CURCE Annual Undergraduate Conference

Currently, there isn’t much research on whether forensic anthropologists include the identification of intersex humans in human remains. Forensic anthropologists tend to have varied training that is related to identifying skeletal remains, but there isn’t much research about how to identify intersex humans after death or whether they have come across intersex in skeletal remains at all, besides those they have classified as ambiguous. In this paper, I will be researching various skeletal remains to see if the current identification methods of identifying sex are accurate in identifying intersex. I will also research ambiguous and undetermined remains to see if …

Maize And Bone: An Evaluation And Expansion Of A Proposed Model For The Differential Diagnosis Of Pellagra In Human Remains, Myra G. Miller

Master's Theses

This study attempts to test and expand a previous study to establish a differential diagnosis of pellagra in human remains (Paine & Brenton, 2006a). Seven individuals with documented pellagra and nine individuals randomly selected for comparison from the Hamann-Todd Osteological Collection were evaluated for caries, alveolar bone loss, periostitis, osteoporosis, cribra orbitalia, and porotic hyperostosis. Results indicate that the pellagra sample had lower rates of caries and alveolar bone loss, and higher rates of periostitis of the tibia and fibula in relation to the comparison sample. No osteoporosis, cribra orbitalia, or porotic hyperostosis was found in the pellagra sample. No …

Experimental Immunology And The Potential For Osteopathological Reconstructions : Pursuing An Experimental Foundation For The Skeletal Inflammatory Index., Megan Elizabeth Duncanson

Electronic Theses and Dissertations

Individuals who mount a strong inflammatory response may produce a shift in the systemic levels of inflammatory mediators, which may lead to a potential hyper-inflammatory phenotype (HIP). Systemic inflammation can increase severity in local inflammatory processes detected in bone lesions. This thesis investigated in vitro if human immune cells pre-treated with inflammatory inducers would affect the inflammatory response against Porphyromonas gingivalis or Staphylococcus aureus (both associated with osteological lesions). We exposed human peripheral blood mononuclear cells to bacterial lysates, or pro-inflammatory cytokines. Sequentially, we exposed the same culture to either P. gingivalis or S. aureus. The final expression of …

The Functional Morphology Of Ingestion In The Platyrrhine Sclerocarpic Harvesters (Platyrrhini, Primates), Zachary Stoffel Klukkert

Dissertations, Theses, and Capstone Projects

The identification of anatomical correlates of diet and feeding behavior in nonhuman primates is an important area of research in biological anthropology. The morphology of the jaws and teeth reflects the phylogeny and adaptations that distinguish taxa and their different ecological niches. Studying the form-function relationships of jaws and teeth in modern species provides a framework for interpreting the diets of extinct species and for inferring the ecological pressures that may have contributed to the evolutionary diversification of primate craniodental morphology. Previous work on modeling primate jaw mechanics has focused largely on the functional context of a closed jaw. Little …

The Archaeology Of Leetown Hamlet: Households And Consumer Behavior In The Arkansas Ozarks, Victoria Ann Jones

Graduate Theses and Dissertations

The hamlet of Leetown, located within Pea Ridge Military Park is the focus of this thesis. The Leetown hamlet played a role in the Battle of Pea Ridge and eventually disappeared before Pea Ridge National Military Park’s establishment in the 1960s. Shortly after the establishment of the Park, archeological investigations began. The resulting archeological investigations from 1962 to 2017 provided a glimpse into the lives of the families of Leetown hamlet within the rural Ozarks. This is an archeological investigation that focuses on establishing the date and function of the buildings within the hamlet as well as the consumer and …
