Review essay: Disentangling feminisms from the cold war

Feminist thinkers have long argued for the centrality of sexuality, gender and women to the Cold War. They have critiqued the sexual language of ‘deep penetration’ and ‘orgasmic whumps’ used to describe nuclear arms race technology and argued that sexuality and gender were central to high‐level political decision‐making and everyday experiences of the conflict.1 Scholars have also begun to question the inverse relationship: they have used the politics of the Cold War as a lens into the history of feminist knowledge production itself. Kelly Coogan‐Gehr's 2011 monograph, for example, challenges conventional genealogies tracing feminist scholarship in the ‘West’ back to the ‘new social movements’ of the 1960s and to women's movements, in particular.2 She argues Cold War pressures have privileged certain ideologies (neoliberal capitalism) and knowledge producers (white women) at the expense of others (socialism, communism and black feminist thinkers) in the preeminent feminist journal, Signs, since its inception in 1975

Arsenic in Poultry Litter: Organic Regulations

Most of the arsenic used as an antibiotic in commercial broiler production ends up in the litter. Using this litter as a soil amendment is not prohibited by the National Organic Program, but 7CFR S205.203(c) of the Rule requires that "the producer must manage plant and animal materials to maintain or improve soil organic matter content in a manner that does not contribute to contamination of crops, soil, or water by plant nutrients, pathogenic organisms, heavy metals, or residues of prohibited substances." Poultry litter applied at agronomic levels, using good soil conservation practices, generally will not raise arsenic concentrations sufficiently over background levels to pose environmental or human heath risks. However, recent studies show that more than 70% of the arsenic in uncovered piles of poultry litter can be dissolved by rainfall and potentially leach into lakes or streams. Thus, organic producers must take care when they handle and apply poultry litter

Health Benefits of Urban Agriculture

Health professionals increasingly recognize the value of farm-and garden-scale urban agriculture. Growing food and non-food crops in and near cities contributes to healthy communities by engaging residents in work and recreation that improves individual and public well-being. This article outlines the benefits of urban agriculture with regard to nutrition, food security, exercise, mental health, and social and physical urban environments. Potential risks are reviewed. Practical recommendations for health professionals to increase the positive benefits of urban agriculture are provided

A comparative study of the influence of buoyancy driven fluid flow on GaAs crystal growth

A systematic investigation of the effect of gravity driven fluid flow on GaAs crystal growth was performed. It includes GaAs crystal growth in the microgravity environment aboard the Space Shuttle. The program involves a controlled comparative study of crystal growth under a variety of earth based conditions with variable orientation and applied magnetic field in addition to the microgravity growth. Earth based growth will be performed under stabilizing as well as destabilizing temperature gradients. The boules grown in space and on earth will be fully characterized to correlate the degree of convection with the distribution of impurities. Both macro- and micro-segregation will be determined. The space growth experiment will be flown in a self-contained payload container through NASA's Get Away Special program

A payload for investigating the influence of convection on GaAs crystal growth

A comparative study of the influence of buoyancy driven fluid flow on gallium arsenide (GaAs) crystal growth was undertaken. Crystals will be grown from melts with different degrees of convective flow including growth in the microgravity environment of space. The space growth of GaAs will be performed in a Get Away Special payload. A well insulated growth furnace was designed for both Earth-based and space-based experiments. The self contained payload will carry two such furnaces in addition to a large battery power source and a microprocessor-based control and data acquisition system for regulating the growth process with high precision. The microcomputer will also monitor the growth conditions and measure and record the acceleration in 3 axes

Purchasing Organic Food in U.S. Food Systems: A Study of Attitudes and Practice

Consumers' preference for organic foods in the context of food aspects considered important in a consumption decision and socioeconomic variables has been examined in this study. The results indicate that food aspects related to naturalness, vegetarian-vegan and production location were critical enhancing regularity of organic food purchases. While the familiarity food aspect was viewed as a 'no' issue as far as organic food purchases are concerned. Results further indicate that females and young people buy organics on a regular basis. In terms of political affiliation and church attendance, the liberals and those who at least visit places worship once a month will also regularly buy organics.Consumer/Household Economics,

Mobile Device Use Among Rural, Low-Income Families and the Feasibility of an App to Encourage Preschoolers' Physical Activity: Qualitative Study.

BackgroundAs mobile devices are becoming ubiquitous, technology-based interventions provide a promising strategy to positively influence health behaviors of families with young children. However, questions remain about the feasibility and acceptability of intervention delivery via mobile apps in low-income, rural settings and among families with preschoolers.ObjectiveThe aims of this study were to understand the content and context of mobile device use for preschoolers; explore parent beliefs on this topic, including the acceptability of intervention delivery via mobile devices; and test a prototype of an app to encourage preschoolers' physical activity with both parents and children.MethodsParents (n=29) were recruited from 5 preschool centers in eastern, rural Colorado to complete a semistructured telephone interview regarding preschoolers' mobile device use. A second sample of parents (n=31) was recruited from the same preschool centers to view the app prototype independently and provide feedback. A third sample of preschool children (n=24) was videotaped using the app in small groups to measure engagement and record their responses to the app.ResultsFive key content areas emerged from the telephone interviews: (1) mobile devices are an important part of families' everyday routines, and parents have parameters governing their use; (2) parents often use mobile devices as a tool for behavior management; (3) parents clearly distinguish between mobile device use for learning versus entertainment; (4) parents have an overarching desire for balance in regard to their child's mobile device use; and (5) parents were generally supportive of the idea of using mobile apps for intervention delivery. From the app prototype testing with parents, participants reacted positively to the app and felt that it would be useful in a variety of situations. Testing with preschoolers showed the children were highly engaged with the app and a majority remained standing and/or actively moving through the entire length of the app.ConclusionsMobile devices are already integrated into most families' daily routines and appear to be an acceptable method of intervention delivery in low-income families in rural Colorado. The physical activity app represents an innovative way to reach these families and, with further improvements based on participant feedback, will provide children with a unique opportunity to practice key movement skills
