Issues Of Commingling Within The Gold Mine Site (16ri13) Collection: Adult Human Humeri And Tibiae, Kinsey Brett Stewart

Masters Theses

Gold Mine (16RI13) is a Troyville ossuary mound site (circa CE 825) in northeastern Louisiana. Approximately 10-20% of the primary mound (Mound A) was excavated over the course of three field seasons (1978-1980), yielding a host of human skeletal remains. Extensively commingled secondary burials make up the majority of interments. The number of individuals represented within the collection (N) has been estimated at 150+ (McGimsey 2004:214), but attempts to quantitatively determine N have produced varied results. Formal analysis of the skeletal collection is complicated by the loss of provenience for many remains as well as additional post-excavation fragmentation …

Two Of A Kind: Implications Of Bilateral Directional Asymmetry On Pair Matching Of Human Limb Bones., Lauren Ashley Garroway

Masters Theses

The task of sorting and analyzing commingled remains can be daunting, depending on the degree of fragmentation, distribution, and contents of the assemblage. The Most Likely Number of Individuals (MLNI) calculation for quantifying the contents of human skeletal assemblages is dependent upon the ability to properly match bilateral elements into pairs. Anthropologists employ numerous methods to reassociate commingled remains into discrete individuals, but the guiding principle used to match sided elements is “general symmetry” (Adams and Konigsberg, 2008; Byrd, 2008). However, different skeletal elements and regions within those elements are variably responsive to a combination of environmental and genetic factors. …

An Assessment Of The Effect Of X-Ray Radiation On Dna Marker Profiles Obtained From Human Teeth, Erin Lynn Knapp

Masters Theses

X-ray radiation is known to destroy cells and damage DNA, yet human remains from forensic anthropology cases are routinely exposed to X-ray radiation as part of the documentation and evidence collection process. If X-ray radiation significantly impacts the quality of DNA extracted from human remains in forensic cases, then the validity of a resulting genetic profile is called into question. To better understand how X-ray radiation affects DNA profiles, specifically profiles consisting of short tandem repeat (STR) markers, this study followed standard forensic X-ray and genetic profiling protocols to obtain DNA profiles on individual molar teeth, before and after they …

Nonparametric Discriminant Analysis In Forensic Ancestry Estimation: An Assessment Of Utilized And Alternative Statistical Methods, David Anthony Mercer

Masters Theses

This thesis evaluates and compares the performances of four discriminant analysis techniques in forensic ancestry estimation using craniometric variables. Giles and Elliot (1962) were the first anthropologists to use discriminant analysis for ancestry estimation. They used Linear Discriminant Analysis (LDA) in an attempt to predict American White, American Black, and American Indian ancestry from craniometric variables. LDA has since been the dominant discriminant technique used for this purpose. It is the method that is exclusively used in FORDISC (Ousley and Jantz, 2005) and, until recently, was the only method applied to forensic craniometric ancestry estimation.

LDA, however, assumes the data …
