The Persecuting Society: Church, Crown, and Jewish Moneylending

The following text is a re-evaluation of Robert Moore's persecuting society thesis in light of recent criticism. The Persecuting Society asserts that the fundamental condition of Jewish persecution in the 13th century was law and order. In other words, persecution had become an institutionalized phenomenon through which medieval Christians--particularly, the English and French monarchies--segregated, both geographically and ideologically, Jews in England and France. The character of such persecution was primarily economic, but based in religious roots. The paper thus also discusses the role of the Church in establishing and justifying social and economic controls against Jews within the English and French persecutional state apparatuses. The text affirms Moore's persecuting society thesis on two accounts: First, that the English and French crowns developed institutions which marginalized and persecuted Jews; secondly, that functionaries of the Church, particularly ecclesiastic functionaries and later popes of the 13th century, did so as well.

Microfinance: A Better Design

My interest in this topic began last summer when I was fortunate enough to travel to Tomatin, Honduras on a microfinance mission with the organization Global Brigades. Microfinance previously an unknown concept to me, but once I saw the effect it had on the lives of those in need, I was immediately sold on its effectiveness. Microfinance stems from the field of developmental aid. While generally understood as one of the most powerful weapons in the fight against poverty, question as to which methods and techniques are the most effective are still unanswered. It is the goal of my thesis to examine the research in the area of microfinance, reveal the most effective methods, and apply these findings to improve the structure of the Global Brigade microfinance institution in Tomatin.

Utilization of Passive Samplers for Water Quality Monitoring of Hexavalent Chromium in Water Treatment Plants

Description

The current EPA regulation for total chromium in drinking water is the MCL standard of 0.1 milligrams per liter or 100 parts per billion (ppb) to avoid dermatological effects. With

The current EPA regulation for total chromium in drinking water is the MCL standard of 0.1 milligrams per liter or 100 parts per billion (ppb) to avoid dermatological effects. With a toxicology study released in 2008 by the Department of Health and Human Services noting that hexavalent chromium is carcinogenic, the EPA is currently reviewing this MCL standard. During this review, the EPA provides monitoring guidance that requires quarterly sampling of surface water for hexavalent chromium. However, these samples monitor the instant in time that they were taken, and do not account for varying concentrations that are time-dependent. This research seeks to develop a method for monitoring hexavalent chromium in water. Using ion exchange technology, passive samplers were developed and installed at the Chandler Water Treatment Plant for a week-long monitoring event. Results show that passive samplers using ion exchange technology provide an accurate assessment of the average concentration of total chromium within the water treatment plant's effluent with 90.3% recovery of Cr(VI) in SIR-100 resin and 62.6% recovery in SIR-700.

Ambivalent Sexism in College Women: Key Beliefs and Outcomes

Description

Gender discrimination and inequality in this day and age points to the existence of ambivalent sexist beliefs. That is, men and women hold outwardly negative or superficially positive sexist beliefs

Gender discrimination and inequality in this day and age points to the existence of ambivalent sexist beliefs. That is, men and women hold outwardly negative or superficially positive sexist beliefs about the innate inferiority of women (Glick & Fiske, 1996; Glick & Fiske, 1997). In the past twenty years, outcomes and effects of women due to these beliefs have been researched extensively. Less common are suggestions or conclusions regarding the underlying existence of these beliefs, though many researchers have related their results to aspects within the Social Identity Theory (1979) and other alike theories involving the self and threats to self. The present study looks at smaller constructs, reporting a relationship between a model of women's identity, including predictors: 1) closeness to women, 2) public regard 3) gender identity centrality, to hostile, benevolent and ambivalent sexist beliefs. A group of N=115 women with ages ranging from 18 to 22 at Arizona State University were administered a survey asking questions about their sexist beliefs and their personal gender values. Results show a significant relationship between predictor variables to hostile sexist beliefs, but not benevolent sexist beliefs. These findings suggest that women's association with their gender-derived identity may parallel with endorsement of sexist beliefs when conceptions of the traditional woman is more salient.

Synthesis and Electrochemical Characterization of Silicon Clathrates for Use in Lithium-Ion Battery Anodes

Lithium-ion batteries are one of the most widely used energy storage solutions today. As renewable energy sources proliferate to meet growth in worldwide energy consumption, it is important that lithium-ion batteries be improved to help capture this energy for use when the demand arises. One way to boost the performance of lithium-ion batteries is to replace the electrode active materials with materials of higher specific capacity. Silicon is one material that has been widely touted as a potential replacement for the graphite used in commercial anodes with a theoretical capacity of 3500 mAh/g as opposed to graphite's 372 mAh/g. However, bulk silicon is known to pulverize after experiencing large strains during lithiation. Here, silicon clathrates are investigated as a potential structure for accommodation of these strains. Silicon clathrates consist of covalently bonded silicon host cages surrounding a guest alkali or alkaline earth metal ion. Previous work has looked at silicon clathrates for their superconducting and thermoelectric properties. In this study, electrochemical properties of type I and II silicon clathrates with sodium guest ions (NaxSi46 and NaxSi136) and type I silicon clathrates with copper framework substitution and barium guest ions (Ba8CuxSi46-x) are examined. Sodium clathrates showed very high capacities during initial lithiation (>2500 mAh/g), but rapidly lost capacity thereafter. X-ray diffraction after lithiation showed conversion of the clathrate phase to lithium silicide and then to amorphous silicon after delithiation, indicating destruction of the clathrate structure as a possible explanation for the rapid capacity fade. Ba8CuxSi46-x clathrates were found to have their structures completely intact after 50 cycles. However, they had very low reversible capacities (<100 mAh/g) and potentially might not be electrochemically active. Further work is needed to better understand exactly how lithium is inserted into clathrates and if copper impurities detected during wavelength-dispersive X-ray spectroscopy could be inhibiting lithium transport into the clathrates.
