The Spectacle of the Invisible: Sephardic Jewish Identity in Multicultural Education

This study assesses from a North American Sephardic (Spanish-Jewish) perspective, the ambiguous relationships among Jews, people of color, and definitions of whiteness in order to re-evaluate multicultural education in the United States. My intent is not to polarize multiple cultural identities but to illuminate and clarify differences in Jewish histories, identities, and cultures. The assumption that all Jews are and can pass as white, and therefore have privilege, denies the complexities of racism, anti-Semitism, whiteness, assimilation, and multiculturalism. In a world where hierarchical divisions narrowly define our perceptions, our relations to power, and our multiple identities, Sephardic non-white Jews are often simultaneously defined and excluded by whites, people of color, and by those who are themselves stereotyped as the monolithic Jew (i.e., the German or Eastern European Jew). By examining historical and social constructions of whiteness, I hope to compel Jews to politicize the construction of our identities within the context of the diaspora and cultural workers to strengthen the vitality, complexity, and legitimacy of a multicultural curriculum

Quality control of gasohol using a micro-unit for membraneless gas diffusion

This work describes the development of a new spectrophotometric flow technique suitable for monitoring of ethanol content in gasohol fuel. Membraneless gas-diffusion (MBL-GD) was applied with one-step aqueous extraction of gasohol (1:2 gasohol/water). Segments of aqueous extract and color developing reagent were allowed to flow into two separate channels in the MBL-GD device. Inside the device, ethanol vapor can diffuse across a small headspace between the two channels (donor and acceptor). Introduction of an air-segment behind the zone of acceptor reagent to stop dispersion of the colored zone greatly improves the rapidity of analysis using this MBL-GD technique. Two methods were developed for quality control of gasohol by measuring ethanol content. Method I is suitable for direct calibration of E5 and E10. Method II is recommended for E20. These methods have high accuracy with good precision (% RSD: 1 to 4.9, n&#8201;=&#8201;45) and have a sample throughput of 26 samples per hour. E10 samples were compared with analysis using a standard GC method. </p

My Private Cloud Overview: A Trust, Privacy and Security Infrastructure for the Cloud

Based on the assumption that cloud providers can be trusted (to a certain extent) we define a trust, security and privacy preserving infrastructure that relies on trusted cloud providers to operate properly. Working in tandem with legal agreements, our open source software supports: trust and reputation management, sticky policies with fine grained access controls, privacy preserving delegation of authority, federated identity management, different levels of assurance and configurable audit trails. Armed with these tools, cloud service providers are then able to offer a reliable privacy preserving infrastructure-as-a-service to their clients

Megawatt solar power systems for lunar surface operations

The work presented here shows that a solar power system can provide power on the order of one megawatt to a lunar base with a fairly high specific power. The main drawback to using solar power is still the high mass, and therefore, cost of supplying energy storage through the solar night. The use of cryogenic reactant storage in a fuel cell system, however, greatly reduces the total system mass over conventional energy storage schemes

Megawatt solar power systems for lunar surface operations

Lunar surface operations require habitation, transportation, life support, scientific, and manufacturing systems, all of which require some form of power. As an alternative to nuclear power, the development of a modular one megawatt solar power system is studied, examining both photovoltaic and dynamic cycle conversion methods, along with energy storage, heat rejection, and power backup subsystems. For photovoltaic power conversion, two systems are examined. First, a substantial increase in photovoltaic conversion efficiency is realized with the use of new GaAs/GaSb tandem photovoltaic cells, offering an impressive overall array efficiency of 23.5 percent. Since these new cells are still in the experimental phase of development, a currently available GaAs cell providing 18 percent efficiency is examined as an alternate to the experimental cells. Both Brayton and Stirling cycles, powered by linear parabolic solar concentrators, are examined for dynamic cycle power conversion. The Brayton cycle is studied in depth since it is already well developed and can provide high power levels fairly efficiently in a compact, low mass system. The dynamic conversion system requires large scale waste heat rejection capability. To provide this heat rejection, a comparison is made between a heat pipe/radiative fin system using advanced composites, and a potentially less massive liquid droplet radiator system. To supply power through the lunar night, both a low temperature alkaline fuel cell system and an experimental high temperature monolithic solid-oxide fuel cell system are considered. The reactants for the fuel cells are stored cryogenically in order to avoid the high tankage mass required by conventional gaseous storage. In addition, it is proposed that the propellant tanks from a spent, prototype lunar excursion vehicle be used for this purpose, therefore resulting in a significant overall reduction in effective storage system mass

Canvas Totes and Plastic Bags: The Political Ecology of Food Assistance Effectiveness at Farmers\u27 Markets in the Twin Cities

In June of 2019, the Trump Administration proposed a policy that could result in three million people losing access to food stamp benefits. The Supplemental Nutrition Assistance Program (SNAP), formerly food stamps, is a governmental food aid program designed to help low-income individuals and families combat food insecurity across the country. According to Minnesota Hunger Solutions, in 2017, 9.5% of Minnesota households were food insecure. In the Twin Cities, SNAP benefits have been accepted at a selection of farmers’ markets since 2003 in order to improve accessibility of fresh, local produce. This paper utilizes a mixed method approach, including qualitative interviews with SNAP participants and key informants, to evaluate the effectiveness of SNAP in the context of three farmers’ markets in the Twin Cities. While research in this field has examined various individual and community coping strategies used to combat food insecurity, little work focuses on the link between SNAP and farmers’ markets as one option for providing local, healthy and affordable food. This paper implements both a broad political ecology framework to analyze the history and implementation of food assistance, and embodiment geography to examine the individual experience at farmers’ markets. Preliminary findings demonstrate the need to provide more comprehensive information to low income shoppers about the restrictions of SNAP, while also ensuring adequate accessibility to farmers’ markets. This research seeks to highlight the applicability of political ecology and embodiment geography to understand relationships at farmers’ markets and enhance food policy

Learning from the whirlpools of existence: Crises and transformative processes as complex and rhythmic phenomena

The aim of this paper is to problematize and enrich the use of the concept of crisis in adult education to theorize further its contribution to the study of transformative processes. This paper discusses first the implications inherent in the adoption of event-based and processual approaches to crises. It seeks then to nuance and problematize the ways in which the relationships between crisis, learning and (trans)formative processes are conceived in adult education, especially through transformative learning theory and biographical approaches. The reflection highlights the difficulty of capturing the fluidity of learning and (trans)formative dynamics. Inspired by Edgar Morin’s paradigm of complexity and illustrated by examples taken from the COVID-19 pandemic, three principles are defined to help conceiving what structures, regulates and reorganizes such dynamics. The contribution concludes by emphasizing the importance of developing a critical awareness of the rhythms that shape educational processes. (DIPF/Orig.
