Paleoepidemiological Analysis Of Trauma In A Roman Period Population From Kellis, Egypt, Circa 50-450 Ad, Isabella A. Graham Sep 2016

Paleoepidemiological Analysis Of Trauma In A Roman Period Population From Kellis, Egypt, Circa 50-450 Ad, Isabella A. Graham

Electronic Thesis and Dissertation Repository

This thesis analyzes human skeletal trauma in a large well-preserved sample (n =268) from the Roman period Kellis site in the Dakhleh Oasis, Egypt. Prevalence was determined for both infracranial and cranial skeletal trauma. The null hypothesis tested was that there are no differences in trauma when stratified by sex and by age cohorts (i.e., 18-35, 36-50 and 51+). Despite the overall trauma prevalence being similar between the sexes when not differentiated by age, the null hypothesis was rejected. Key differences that occurred between the sexes were that males suffered greater malintent and occupational traumas, whereas osteoporosis was the major …


A Statistical Investigation Of Nonmetric Vertebral Traits With A Skeletal Population Sample From The Dakhleh Oasis, Egypt, Tiffany A. Sarfo Sep 2014

A Statistical Investigation Of Nonmetric Vertebral Traits With A Skeletal Population Sample From The Dakhleh Oasis, Egypt, Tiffany A. Sarfo

Electronic Thesis and Dissertation Repository

This paleogenetic study utilizes 17 nonmetric epigenetic vertebral traits to determine their suitability for studying past genetic relationships. The samples utilized were from Egypt’s Dakhleh Oasis. Though infracranial nonmetric traits have a limited role in the study of past population genetics, this study has shown their value for elucidating past genetic patterns for intragroup analysis. The key to their utilization is to test the epigenetic factors (e.g., age, sex, symmetry and intertrait correlations) which were done using a number of statistical tests including Phi coefficient, G-test and the Odds ratio. This study utilized a novel set of spatial statistics to …


In Search Of A Cause: An Etiological Analysis Of Manubrial Porosity, Jose Sanchez Sep 2014

In Search Of A Cause: An Etiological Analysis Of Manubrial Porosity, Jose Sanchez

Electronic Thesis and Dissertation Repository

Few studies in paleopathology focus on the sternum as a unit of analysis to determine how it can contribute to disease diagnosis in the past. This thesis tested the null hypothesis that manubrial porosity was not associated with respiratory disease or pulmonary tuberculosis. One hundred fifty-four individuals from the Luis Lopes Skeletal Collection were assessed for manubrial porosity. This study sought to be as comprehensive as possible, and thus tested several variables to identify any significant associations with manubrial porosity. Using the odds ratio, 95% confidence interval, and chi-square tests, significant associations exist between manubrial porosity, adolescence, and sternal body …
