The forensic analysis of soil organic by FTIR

In order to elucidate the discriminating power of various soil analytical techniques, over 100 soils samples were analyzed using conventional analysis (i.e., color, percent organic and density gradient) and a novel FTIR technique. The FTIR technique involves collecting a spectrum of a soil sample that has been oxidatively pyrolysed, and therefore all organic have been degraded. This spectrum is subtracted from the spectrum of the same sample that contained the organic prior to pyrolysis. This resultant IR spectrum represents the organic portion of the sample. The use of organic components increases the discrimination in soils that are otherwise similar. We have illustrated the usefulness of this technique by selecting four soil samples, which have identical Munsel color values but can be discriminated by subtractive ETIR. We propose that the ETIR spectra of the organic portion of soil serves a useful purpose in forensic investigations.     

‘Peace with the earth:’ Women and the environmental movement in Sweden

Women active in the contemporary Swedish environmental movement draw much of their inspiration from twentieth century feminist Elin Wägner (1882–1949) who in the 1930s saw connections between environmental issues, feminism, and matriarchal cultures of the past. Contemporary women writers, poets, and artists celebrate periods in which both women and nature seemed to be more powerful than they are today. Contemporary women are most active in environmental issues that involve the reproduction of the human species (such as nuclear issues) and their own reproductive labor as it affects themselves, the family, and the state (such as pesticides, food quality and distribution, and work environments). These issues are analysed as a ‘politics of reproduction’ that leads to conflicting strategies of equality politics, women's culture politics, and alternative ‘green’ politics. These conflicting strategies exemplify contradictions inherent in both the wider women's movement and the ‘women and environment’ movements throughout the world today.     

School vouchers and academic performance: results from three randomized field trials

This article examines the effects of school vouchers on student test scores in New York, New York, Dayton, Ohio, and Washington, DC. The evaluations in all three cities are designed as randomized field trials. The findings, therefore, are not confounded by the self‐selection problems that pervade most observational data. After 2 years, African Americans who switched from public to private school gained, relative to their public‐school peers, an average of 6.3 National Percentile Ranking points in the three cities on the Iowa Test of Basic Skills. The gains by city were 4.2 points in New York, 6.5 points in Dayton, and 9.2 points in Washington. Effects for African Americans are statistically significant in all three cities. In no city are statistically significant effects observed for other ethnic groups, after either 1 or 2 years. © 2002 by the Association for Policy Analysis and Management.     

How the indigenous got seats at the UN table

Indigenous peoples are the only distinct segment of national populations having voting membership in UN bodies devoted to defining their rights and advancing their concerns. This unusual result was the result of the confluence of three factors familiar to students of transnational social movement politics: a) presence within UN offices and bodies of supporters opening forums and agendas to indigenous concerns, b) deference to the growing network of indigenous activists by anthropologists—the professional community best placed to serve as advocates speaking on behalf of indigenous communities, and c) indigenous activists' success in developing and projecting a globally-valid indigenous identity as “peoples” simultaneously uniting the various indigenous communities and providing a rationale for establishing voting rights that enough other actors could be persuaded to accept. Comparison with UN treatment of other groups indicates that indigenous voting rights are more likely to remain an isolated success rather than a harbinger of similar practices in other UN bodies.     

The National Partnership for Environmental Priorities Program

The National Partnership for Environmental Priorities (NPEP) program was created by the U.S. Environmental Protection Agency (USEPA) to reduce or eliminate the nation's production of hazardous wastes and products. The NPEP is a voluntary program that provides incentives to public, private, and federal organizations that minimize their use and generation of thirty-one priority chemicals. These chemicals are considered to be persistent, bioaccumulative, and toxic in the environment and present health risks to human and ecological receptors. The USEPA estimates that 90 percent of priority chemicals are used or produced during manufacturing of various household and industrial products and, as a result, end up in municipal and industrial waste streams. Ultimately, these chemicals find their way back into the environment through wastewater discharges, incineration, or other disposal practices. The NPEP program supports the goals of the National Waste Minimalization Program by encouraging simple waste minimalization solutions such as recycling, replacement, or elimination of wastes or products that contain priority chemicals, and cradle-to-cradle management of waste. Although the USEPA does not limit waste minimalization practices to only the priority chemicals, the program has set specific goals to track the elimination of these thirty-one chemicals to the environment on an annual basis.
