Silencing And Assaulting The Feminine: An Analysis Of Institutions That Perpetuate A Rape-Supportive Culture, Melissa Territo

Masters Theses

Since 1700, rape has been a publicly discussed topic. Past research has focused on the effects that socialization practices, patriarchy, and hegemony have on sexual violence and mediated representations of gendered violence in the United States. This thesis explores two institutions, social structures, and cultures that contribute to and perpetuate a rape supportive culture in the United States-the penal and fraternity systems. By approaching and analyzing sexual assault as socially constructed and communicated through the institutional structures of the penal and fraternity systems, we are equipped to better understand how society and media (re )create and perpetuate a patriarchal rape …

Cloning, Overexpression, Purification And Characterization Of Gcp Ii Homologous Metalloprotein From Caulobacter Crescentus, Dilani Nilushika Gigiriwala Gamage

Masters Theses

A novel zinc metalloprotease gene isolated from Caulobacter crescentus (CCM) was cloned and overexpressed in Escherichia coli. A protease database search using MEROPS predicted this protein is a homolog of Glutamate Carboxypeptidase II (GCP II), a zinc metalloprotease found in humans and many other organisms. GCP II is considered as a suitable target for treating stroke, neurological disorders and a biomarker for prostate cancer. Chromatographic purification of CCM produced pure protein in milligram quantities. Molecular weight detern1ination using MALDI-TOF showed 51,582 Da and the extinction coefficient was found to be 33,007 M"1cm·1. Metal analysis and substrate profiling showed neither sufficient …

Electrochemical And Spectroscopic Characterization Of A Polypyridyl Ru(Ii) Complex Containing A Fused Alloxazine, Waynie Wilson Olaprath

Masters Theses

Phenanthroline pteridinedione (pptd) is an alloxazine derivative capable of 2e/ 2H+ transfer reactions. Coordination of pptd to a Ru(II) metal center allows for the synthesis of water-soluble metal complexes capable of being reduced by as many as 6 Hatoms making them candidates to be electrochemical mediators. This thesis describes the synthesis and characterization of pptd and [Ru(bpy)2(pptd)](PF6)2(b py = 2,2-bipyridine). The dipyrido[3,2-a: 1' ,2' -c] phenazine (d ppz) and [Ru(bpy)2(d ppz) ](PF6)2 are also synthesized and studied in order to distinguish the properties of the free and coordinated pteridinedione-based pptd ligand from the well-characterized phenazine based ligand.

Interaction Of Apoe With Estrogen In The Olfactory System During Nerve Maintenance And Recovery, Michael M. Tonsor Ii

Masters Theses

Estrogen replacement profoundly aids in nerve regeneration after injury in adult mammalian models. Estrogen replacement also protects against olfactory dysfunction in mammals. The mechanism underly1ng estrogen's neuroprotective effects remains ambiguous. My goal is to investigate and better clarify if apolipoprotein E (apoE ), a lipid transporting protein, is a critical intermediary to estrogen's effects on nerve maintenance and regeneration.

My hypothesis is that apoE is a mediator of estrogen's beneficial effects. This hypothesis is based on the following observations from previous studies. First, olfactory nerve regeneration was delayed in apoE-gene knockout (KO) mice as compared to wild type (WT) mice. …

Taking Out The Trash: Critiquing The Equipment For Living Of White Trash Films, Tasha Rose Dunn

Masters Theses

Over the past decade, class has become a lightning rod issue in the United States as the gap between the rich and the poor continues to widen. One of the main reasons for growing class segregation is the mere fact that U.S. culture carries enormous social anxieties about poverty and, in turn, blame the poor for being poor. As a result of hegemonic beliefs about class, crude discourses are formed and fostered through the mainstream media creating both inaccurate and damaging portrayals. Such damaging portrayals are immediately evident in a variety of mainstream Hollywood films produced in the past decade …

Analysis Of Transcription Factor Promoter Binding In Rat Hepatoma/Fibroblast Hybrids, Jordan C. Angle

Masters Theses

When hepatomas (liver cancer cells) are fused with fibroblasts (undifferentiated body cells), there is complete extinguishing of all tissue-specific gene expression. Once it was discovered that many hybrid cell lines do not express needed transcription factors for liver-specific gene transcription, the factors were reintroduced and forced to express through the use of plasmids. Even if the two primary transcription factors were present in the system, downstream tissue-specific gene expression was not rescued. To examine potential mechanisms for the repression of liver-specific gene expression in hepatoma x fibroblast hybrid cells, chromatin immunoprecipitation (ChlP) was used. This procedure allows the liver-specific gene …

Coercion In U.S. Foreign Policy: Evaluating The Utility Of The Jentleson And Whytock Model, John D. Hamilton

Masters Theses

This thesis seeks to test the utility of the Jentleson and Whytock (2006) model, which stems from their study of U.S. foreign policy with Libya. Their study established a model of foreign policy coercion, which they maintain helps explain why Libyan foreign policy changed so radically during the presidency of George W. Bush. The model is applied to American policy, implemented from the Carter administration to that of George W. Bush, towards Iran, Burma (Myanmar) and North Korea. The coercive strategies used by each administration are compared against the prescription and projection purported by the model in order to determine …

The Effects Of Technology On Literacy(S), Thomas Glen Petersen

Masters Theses

"One of the challenges when measuring the effects of technology on literacy(s) is finding a control group where technology; does not play a major role in the culture. The Amish successfully live in a Technocracy where mechanical/electronic tools are used only when absolutely necessary; the Amish are not dependent on them for survival. The crux of the Amish philosophy is humility, serving the community and serving God. Ironically, they have suffered tremendous repercussions for adopting a wholesome, selfless lifestyle which is contrary to most popular world views, regardless of religious or spiritual views"--Purpose, page 40.

Fatigue Of Friction Stir Welded Lap Joints With Sealants, Kenneth Doering

Masters Theses

"A lack of understanding of corrosion fatigue in friction stir welded aluminum joints prevents friction stir welding from being implemented in aerospace applications. Fatigue testing reveals a 60-75% reduction in the fatigue life of friction stir welded aluminum lap joints immersed in 3.5% NaCl solution (corrosion fatigue) compared with that of lap joints tested in ambient air. The loss in fatigue life is attributed to accelerated fatigue cracking due to hydrogen environment embrittlement. Two polymer sealant candidates are investigated: silicone rubber and nylon-11. Both sealant candidates can be applied prior to welding and seal the faying surface gaps in lap …

Primarily based on the satellite images of Sri Lanka taken before and during the 2004 tsunami, this study analyses: How could mechanical satellite images, taken automatically by a machine in orbit, become an object of profound emotional meaning?; How do viewer's experiences, knowledge, and discourse affect their interpretations of mechanical artifacts?; How are tsunami satellite images connected to affective responses by viewers?; How …

The Corrosion Of Ni₃Si Alloys In Sulfuric Acid, Christopher Marc Larson

Masters Theses

"Hydrogen production from water, the world's most renewable natural resource, can provide an economical and sustainable form of energy for the future. One means to achieve this is with a nuclear reactor-based sulfur-iodine (S-I) thermochemical cycle. Currently there are few materials available, other than precious metals like gold and platinum, that possess the corrosion resistance and mechanical properties required for the sulfuric acid decomposition loop of the S-I process. However, alloys based on Ni₃Si show promise to be a more affordable, corrosion resistant materials option for this technology. In this study, the corrosion behavior of NiSi₂₂ and NiSi₂₀(Nb,Ti)₃ alloys in …

Comparison Of In-Planta Sampling Methods For Delineating Groundwater Contaminants, Kendra Marie Waltermire

Masters Theses

"Plants directly interact with surrounding water, air, and soil, collecting and storing chemicals and elements from the surrounding environment. Two new and innovative sampling methods have been developed in which this valuable data can be accessed to replace as well as supplement contaminated-site investigations. When determining the extent of the plume on a contaminated site, groundwater sampling may be limited due to time, site access, and expense. Using new techniques that place sampling devices in trees on site, we can sample trees naturally occurring on a contaminated site or those planted in phytoremediation or redevelopment efforts. Using these sampling devices, …

Experiments And Modeling Of Shear-Driven Film Separation, J. L. Wegener

Masters Theses

"Dynamic thin liquid films driven by an adjacent gas flow have been subject to many investigations due to the presence of such films in many engineering applications. More specifically though, the behavior of such films at a sharply expanding corner has received little attention, but can be observed in internal combustion engines, liquid atomizer systems, refrigerant flows in evaporators, and film drag over wetted surfaces. Efforts to validate computational models of the propagation and separation of films are limited by the lack of reliable non-intrusive techniques to measure and analyze dynamic film parameters. In this study, film propagation models and …

Single Muslim Young Adults: Negotiating Identities, Religion And Desire, Zarinah El-Amin Naeem

Masters Theses

This ethnographic thesis is an empirically rich, critical analysis of the singlehood of Muslim young adults. Based on interviews with 21 single Muslims aged 18-36, and participant observation of Muslim spaces, I demonstrate that while Islam and Muslim communities present "ideal" behaviors, Islam is not alone. Instead, like identity, the singlehood of American Muslims is created and recreated through dialectical relationships with several cultural "wombs" including religion, popular culture, family, and ethnicity. As Muslim young adults encounter these often contradictory ideologies, they accept and reject parts, and negotiate their identities, religion and desires - all while struggling to maintain a …
