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 âdeep penetrationâ and âorgasmic whumpsâ used to describe nuclear arms race technology and argued that sexuality and gender were central to highâlevel political decisionâmaking 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 CooganâGehr's 2011 monograph, for example, challenges conventional genealogies tracing feminist scholarship in the âWestâ back to the ânew social movementsâ 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 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
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
Categorizing Humans, Animals, and Machines in Mary Shelleyâs Frankenstein
From Plato to Descartes and Kant and now to modern day, there is a general idea that pervades Western society. This idea is about the uniqueness and superiority of the human being. We are rational and conscious beings that apparently stand alone in the world, separated intellectually from animals and biologically from machines. The relationship between humans, animals, and machines is a tumultuous one and it is not easily definable. For many classical philosophers, this relationship has always been a hierarchy. Humans are on the top and animals and machines fall somewhere below. These beliefs have created a distinct category for the three terms that leaves no room for overlap. Because of the great disparity between these groups, the animal and machine have come to be known as the âOther.â This title demonstrates that they are markedly disregarded and disrespected.
All of the points indicated in regard to the relationship between humans, animals, and machines can be seen in the Frankenstein novel. Victor Frankenstein, the maker of the creature, has all of the typical ideas about the rarity and dominance inherent in humans. When working on his creature, he thinks of everything mechanistically. The human remains that he has collected are simply parts in the machine he wants to build. The whole creation is just a scientific procedure. What Frankenstein is doing is trying to make an artificial human or a cyborg. Once his experiment is complete, the creature becomes alive. He is not human-like in appearance and he cannot talk. Frankenstein flees in terror from the monster that he has brought into existence. He treats his work as some sort of animal not worthy of his attention any more. The creature runs away as well and is treated by everyone like a demon. He hides and it is during this time that he learns to read, write, and speak. He has learned what humans prize the most as something that is their own: language. At this point in time when the creature is most clearly human, he still has the qualities of animal and machine. Frankensteinâs creature has blurred the distinct categories of humans, animals, and machines. By analyzing the most contemporary philosophical writing on the boundaries between humans, animals, and machines as well as recent critical analyses on Frankenstein regarding these categories, a more unified view of the separate groups emerges
