Exploring Social Identity Through Stable Isotope Analysis In The Kellis 2 Cemetery, Kaitlin East Jan 2015

Exploring Social Identity Through Stable Isotope Analysis In The Kellis 2 Cemetery, Kaitlin East

Electronic Theses and Dissertations

The material remains of ancient Egypt provide extensive and wide ranging data about the empire throughout its history. However, little evidence is available from ancient Egypt, or any past culture, with which to rebuild an image of social identity or individual experiences. This is especially problematic when the dominant narrative ignores experiences of minorities and minimizes the variation existing throughout the empire. Stable isotope analysis has the potential to reveal variability in lived experience of past peoples by acting as a proxy for behavior that can be analyzed from bone. Such an approach has been applied on individuals from the …

Identification Of The Domain(S) In Protein Disulfide Isomerase Required For Binding And Disassembly Of The Cholera Holotoxin, Laura Herndon Jan 2015

Identification Of The Domain(S) In Protein Disulfide Isomerase Required For Binding And Disassembly Of The Cholera Holotoxin, Laura Herndon

HIM 1990-2015

Cholera, caused by the secretion of cholera toxin (CT) by Vibrio cholerae within the intestinal lumen, triggers massive secretory diarrhea which may lead to life-threatening dehydration. CT is an AB5-type protein toxin that is comprised of an enzymatically active A1 chain, an A2 linker, and a cell-binding B pentamer. Once secreted, the CT holotoxin moves from the cell surface to the endoplasmic reticulum (ER) of a host target cell. To cause intoxication, CTA1 must be displaced from CTA2/CTB5 in the ER and is then transferred to the cytosol where it induces a diarrheal response by stimulating the efflux of chloride …

HIM 1990-2015

The Party Exercise found on countless career guidance websites and popularized by the best-selling, job-hunting book What Color Is Your Parachute (Bolles, 2015) purports to provide an estimate of an individual's Holland's code. This study examines whether this commonly used Party Exercise accurately predicts an individual's Holland's code (Holland, 1997). Undergraduate students (N=473) completed The Party Exercise and then the Self- Directed Search (Holland & Messer, 2013). The results of this study do not support the use of this popular “Party Exercise” as a valid estimate of an individual's Holland code.
