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 …

Macromorphological And Microscopic Effects Of Temperature In A Controlled Environment On The Process Of Decomposition In Bone, A. Marie Cato

All Graduate Theses, Dissertations, and Other Capstone Projects

This research explores the idea that the processes and rate of bone decomposition are affected by differential temperatures after death. Previous research supports changes in the molecular structure of bone due to different weather conditions, in addition to gross macroscopic changes, but there remain issues in understanding how these possible changes affect decomposition overall. In this research, I will explore how the freeze-thaw cycle affects decomposition, and what the relationship between weathering on bone and the natural decomposition process is. My hypothesis is that the freeze-thaw cycle will induce further decay, steady higher temperatures will speed up decomposition, and freezing …

Modeling Prehistoric Health In The Middle Cumberland Region Of Tennessee: Mississippian Populations On The Threshold Of Collapse, Christina Laiz Fojas

Doctoral Dissertations

This research explores differences in mortality and survivorship resulting from factors associated with the abandonment of the Middle Cumberland Region (MCR) of Tennessee during the Mississippian period (ca. 1000-1500 AD). My dissertation investigates whether individuals from the Late Mississippian period had a greater risk of death than individuals from the Early Mississippian period. Adult age-at-death estimates (n=545) were calculated using Transition Analysis, a Bayesian maximum likelihood method. Gompertz and Gompertz-Makeham hazard models were utilized to reconstruct the mortality profile of the MCR as they model human adult mortality and generate robust parametric mortality profiles. Rather than recount the prevalence of …

Investigating Cranial Variation In Japanese Populations Using Geometric Morphometrics, Beatrix Dudzik

Doctoral Dissertations

The Japanese archipelago exhibits an immense amount of variation in culture and history, despite the lay population mostly considering the modern Japanese a homogeneous population. Japan has experienced an amazing amount migration activity. These migration events are well represented in the archaeological record and have provided fodder for hypotheses proposed for peopling of the new world.

Biological anthropologists have tested hypotheses surrounding the initial peopling of the islands using linear data in conjunction with non-metric traits of the skull. Recent molecular studies have provided evidence for population substructure, which suggests an original founding group of North Asian descent, and a …

Is Quantitative Ultrasound A Valid Technique For Assessing Bone Quality In Deceased Infants?, Miriam Elizabeth Soto Martinez

Doctoral Dissertations

There is no quantitative method for evaluating infant bone quality that is non-invasive, portable, brief in scan duration, and does not use ionizing radiation. This study investigates the relationship between components of infant bone quality and a measure of quantitative ultrasound (QUS), speed of sound (SOS), to provide insight into the validity of QUS as a diagnostic tool for evaluating infant bone quality. The study sample was comprised of 78 infants between the age of 30 weeks estimated gestational age and 12 postnatal months receiving an autopsy at the Harris County Institute of Forensic Sciences and Texas Children’s Hospital. Bone …

A Comparative Ontogenetic Study Of Biomechanical Adaptations In The Long Bones Of South African Khoisan And Sadlermiut Inuit, Kaye-Lynn Boucher

Electronic Thesis and Dissertation Repository

This research examines and compares the biomechanical adaptations of juveniles from two different climate-adapted populations: Khoisan foragers from South Africa and Sadlermiut Inuit from Nunavut, Canada. Cortical bone measurements were recorded at three diaphyseal locations on the Sadlermiut and Khoisan humeri, tibiae and femora using biplanar radiographs. Biomechanical strength properties were calculated using the Eccentric Ellipse Method (EEM). EEM calculations were interpreted with consideration to the known behavioural patterns of the two groups. Humeral AP and torsional bending strength were greater in the Sadlermiut compared to the Khoisan – most likely caused by kayak paddling among the Sadlermiut. Few differences …
