Entanglements Of Teenage Food Security Within High School Pantries In Pinellas County, Florida, Karen T. Díaz Serrano

USF Tampa Graduate Theses and Dissertations

Food insecurity has the ability to shape an individual’s or a family’s everyday life and take emotional, psychological, and physical tolls. Among adolescents, not having access to nutritious food could lead to physical effects during growth and development. Moreover, the stress and anxiety of not knowing where their next meal is coming from and the social stigma associated with being food insecure can have negative effects on mental health. A recent solution to these issues is locating food pantries in high schools. Purpose: This exploratory study examined how high school students in Pinellas County, Florida perceive the use of a …

The Applicability Of The Postmortem Submersion Interval Estimation Formula For Human Remains Found In Subtropical Aquatic Environments, Kara L. Dicomo

USF Tampa Graduate Theses and Dissertations

Within the past decade, several attempts have been made to standardize a method for estimating postmortem submersion intervals (PMSI); however, the majority of these studies have focused on data from a temperate climate which cannot be taken as representative of large portions of the globe. Thus, there are large portions of the earth in which the methodology from these studies may not be able to accurately estimate PMSI which has the potential to leave investigators in these other climatic zones at a disadvantage. This presentation presents a case study into the applicability of two Total Body Scoring Systems (TADS) utilized …

The Early Medieval Transition: Diet Reconstruction, Mobility, And Culture Contact In The Ravenna Countryside, Northern Italy, Anastasia Temkina

USF Tampa Graduate Theses and Dissertations

This research project evaluates the effects of increased mobility and culture contact on dietary practices, and on dietary variation among people buried at two northern Italian sites, Chiunsano di Ficarolo and Chiesazza di Ficarolo, located near the ancient Roman capital of Ravenna and dating 4th to 7th century CE. The Early Medieval period was a time of change, political instability, migration and invasion of the “barbarian” tribes, and diet was not unaffected. In particular, it is hypothesized that a new staple crop, millet, was introduced and that meat consumption had increased. The goal of this research is to use stable …

Pregnancy And Fertility Amongst Women With The Mthfr C677t Polymorphism: An Anthropological Review, Caroline A. Maclean

USF Tampa Graduate Theses and Dissertations

Effects of the MTHFR C677T allele on reproduction include multiple complications. The frequency of births with neural tube defects, Down Syndrome, or recurrent pregnancy loss of CC, CT, and TT mothers was measured using data collected from existing literature. Total participants n=2605 (n=1111 cases, n=1494 controls). Results show that folic acid supplementation did not prevent the incidence of NTD pregnancy in CT women. Furthermore, CT women are more fecund overall, producing more pregnancies than CC and TT women. While CT case women did have higher incidences of RPL, NTD pregnancy and DS pregnancy, this is due to the overall greater …

Identifying Skeletal Puberty Stages In A Modern Sample From The United States, Jordan T. Wright

USF Tampa Graduate Theses and Dissertations

Investigating the onset and progression of puberty can provide insight and evidence for social changes regarding the transition to adulthood. There are also many social factors that can lead to variation in the timing of the onset and progression of puberty. Methods created by Mary Lewis and Fiona Shapland for assessing changes in skeletal development associated with pubertal timing were applied to computerized tomography scans (n=400) from the New Mexico Decedent Image Database and recorded in an attempt to identify adolescent growth trends in a modern skeletal sample from the United States. This is a novel study using the methods …

Listening To Women: Using A Mixed-Methods Approach To Understanding Women’S Desires And Experience During Childbirth, Nicole Loraine Falk Smith

USF Tampa Graduate Theses and Dissertations

This dissertation is based on evolutionary medicine and applied anthropological research where the narratives and biology of modern women are used to inform evolutionary theory, specifically obligate midwifery, and modern birth practices. Improvements to the US maternity care systems are needed as rates of maternal mortality and morbidity are continually higher than rates in other technologically advanced nations. Additionally, women birthing under the technocratic model of care, as is predominant in the US, report trauma and post-traumatic stress disorders due to their birthing experience, and more women are experiencing postpartum depression. Thus, I seek to use an evolutionary medicine perspective …

Characterizing Childhood And Diet In Migration Period Hungary, Kirsten A. Verostick

USF Tampa Graduate Theses and Dissertations

This project investigates children, childhood and diet of two different Migration Period (4^th-8^th century AD) populations, the Gepids and the Avars, in the Great Hungarian Plain. The main goal was to assess whether there are differences in treatment of children and differences in breastfeeding and weaning practices in these distinct sites and populations. Secondarily, this research also focused on characterizing diet for the Gepids and the Avars at four different sites from the Migration Period, to understand how the migration and settling into the region and the assimilation of other groups into the two populations affected their …

Maternal Social Status, Offspring 2d:4d Ratio And Postnatal Growth, In Macaca Mulatta (Rhesus Macaques), Juan Pablo Arroyo

USF Tampa Graduate Theses and Dissertations

Early life exposure to stressors can disrupt growth and development, resulting in long-term compromised function and increased risk for disease throughout the lifecourse. Maternal exposure to psychosocial stressors (i.e., stressors derived from social status, social inequalities, and social interactions) during pregnancy has been associated with reduced fetal growth, adverse birth outcomes, and increased morbidity for the offspring later in life. Maternal hormonal responses to stress, such as fluctuations in glucocorticoids (e.g., cortisol) and androgens (e.g., testosterone), can result in increased developmental instability, interfere with offspring growth in-utero, and may alter developmental processes of sexual dimorphism. Second digit to fourth digit …

Laser-Induced Breakdown Spectroscopy For Elemental Analysis In Bioarchaeology And Forensic Anthropology, Kelsi N. Kuehn

USF Tampa Graduate Theses and Dissertations

Within bioarchaeology and forensic anthropology, the current processes of differentiating between individual human skeletal remains are imprecise, costly, and inefficient. A novel analytical technique within anthropology, laser-induced breakdown spectroscopy (LIBS) can aid in the identification of human remains using rapid laser ablation occurring at the micro-scale, making the technique virtually non-destructive to the sample. Considering this, LIBS could offer a superior method for materials discrimination and human identification. This research sought to examine whether LIBS can be used to obtain elemental signatures within bones to distinguish individuals from one another in a rapid, non-destructive manner. Seven human skeletal donors and …

Exploring Variations In Diet And Migration From Late Antiquity To The Early Medieval Period In The Veneto, Italy: A Biochemical Analysis, Ashley B. Maxwell

USF Tampa Graduate Theses and Dissertations

This project tests the hypothesis that the Langobard migration into the Roman/Byzantine Veneto (northeastern Italy) resulted in significant dietary changes from Late Antiquity (4-5th centuries AD) to the Early Medieval period (6-8th centuries AD). At the end of the Great Germanic Migrations in AD 568, Langobards from Pannonia entered and occupied two-thirds of the Italian peninsula. It is unclear how large these migrations were, as historical documents exaggerate mass movements; however, conservative estimates suggest they made up 8% of the areas they occupied. The degree to which the Langobards influenced economic change and subsistence in this area is poorly understood. …

The Association Of Size Variation In The Dental Arch To Third Molar Agenesis For A Modern Population, Devin N. Williams

USF Tampa Graduate Theses and Dissertations

The frequency with which individuals do not develop their third molars, or wisdom teeth, is increasing worldwide. This current topic of human evolution is relevant to the research of anthropologists, geneticists, dentists, and other researchers involved in the study of human dentition. Many explanations have been offered to account for the prevalence of molar agenesis including, evolutionary, environmental, and genetic theories. The purpose of this research project is to determine the frequency of third molar agenesis and investigate the relationship between third molar agenesis and maxillomandibular jaw dimensions in a sample of orthodontic patients. This research tests the hypotheses that: …

Evolution, Ecology, And Disparities: Constructing Stature, Immune Functioning, And Reproduction In Brazilian Quilombo, And United States, Women, Anna C. Rivara

USF Tampa Graduate Theses and Dissertations

The purpose of this dissertation is to test how growth, reproduction, and immune functioning interact in two populations of adult women residing in vastly different socio-economic and ecological environments, the Kalunga quilombo in Brazil, and the United States of America. The presence of life history trade-offs was tested to determine how the different envirnonments, and socio-ecological contexts of the populations were creating differential risks for health and reproductive outcomes, and life history trade-offs.

I hypothesized that the Kalunga people, living in very difficult and harsh conditions, would experience greater amounts of, and more severe, life history trade-offs than the U.S. …

Costumbres, Creencias, Y “Lo Normal”: A Biocultural Study On Changing Prenatal Dietary Practices In A Rural Tourism Community In Costa Rica, Allison Rachel Cantor

USF Tampa Graduate Theses and Dissertations

This study explores the relationship between tourism, the nutrition transition, and prenatal dietary practices in the Monteverde Zone, Costa Rica. This rural tourism community, located in the central highlands of Costa Rica, has seen rapid growth and development since the tourism boom in the early 1990s, leading to changes in the local food system and increased food insecurity. This investigation added to this work by identifying the ways that prenatal dietary practices have shifted over time in the context of increased tourism and the concomitant nutrition transition, and by describing the relationship between food insecurity and nutritional status among pregnant …

The Relationship Of Childhood Stress To Adult Health And Mortality Among Individuals From Two U.S. Documented Skeletal Collections, Late 19Th To Early 20Th Centuries, Rhonda Coolidge

USF Tampa Graduate Theses and Dissertations

Although the association between social inequality and poor adult health is well established, the mechanisms by which inequality is translated into poor adult health are less clear. Increasingly, evidence suggests that many adult health problems and health disparities have their origins in early life; the developmental origins of health and disease (DOHaD) hypothesis provides an explanatory mechanism linking adverse early life conditions with permanent structural or functional changes that increase the risk for disease. This hypothesis is consistent with bioarchaeological research noting reduced lifespan among individuals exhibiting signs of childhood stress.

The principal aim of this dissertation is to contribute …
