Comparing two analytical methods: minimal standards in forensic toxicology derived from information theory

Frequently, new instrumentation and techniques are being applied to casework without an adequate knowledge of how this new technology compares to acceptable analytical procedures. Information theory provides a mathematical method to estimate the identification power of various analytical procedures and predicts if the new method produces a better or poorer confidence in the analysis than an accepted method. This paper makes comparisons based on relative informational power and discusses methods to make those estimates. With the procedures outlined in this paper, an analyst can estimate if a novel technique has the opportunity of reaching the accepted analytical methodology and, if necessary, identify places where the greatest improvement can be made to reach this equilivalence. Even though relative information theory can dismiss some proposed techniques before any analysis starts, it cannot verify if a given technique is adequate for a particular task. For that purpose, a complete procedural verification must be undertaken.     

Stable isotope ratios as a tool in microbial forensics--Part 1. Microbial isotopic composition as a function of growth medium

The stable isotope ratios of a seized pathogen culture could potentially reveal information about the environment in which the agent was produced. In this paper we describe general relationships between stable isotopes of carbon, nitrogen, and hydrogen in bacteriological culture media and spores of Bacillus subtilis, an endospore-forming soil bacterium. In numerous media that varied both in nutrient composition and water stable isotope ratios, medium to spore enrichment in carbon isotopes was 0.3 +/- 2.0% per thousand (parts per thousand), and in nitrogen, 4.5 +/- 0.7% per thousand. We achieved mass balance for the contribution of hydrogen isotopes from nutrients (70%) and water (30%) to spores in independent experiments by varying the isotope ratios of nutrients or water. A model was derived for predicting the isotope ratio values of spores from those in nutrients and water.     

Frontier expansion and settlement in lowland Bolivia

This article examines the expansion of cash crop production into the lowland Bolivian frontier and explores the dynamics of class formation that shaped peasant political consciousness. It discusses the factors that moulded local‐level response to the conditions created by capitalist development: the process of social differentiation that affected settlers and the relationship between subsistence agriculture and wage labour; the tensions between settlers and large‐scale entrepreneurs; and changing state policies and economic conditions. It concludes that rigid analytic distinctions between peasants and proletarians ignore the historical development of production relations in Bolivia.     

“I have never met the normal woman”: Stella Browne and the politics of womanhood

Abstract

F. W. Stella Browne (1880–1995) and her views on female sexuality have been much discussed of recent years. These discussions have tended to rely on a limited number of her copious (if often hard-to-find) writings, and have also failed to take into account where Stella, as an individual woman, was coming from. In the light of ongoing researches into her life and career, this article locates her writings in her life of activism in a wide variety of causes. It argues that her opinions about women's needs do not conform to a simplistic model of a ‘New’ feminism of difference, and that her relationship to the thought of contemporary male sexologists has been presented in a one-dimensional and misleading way. Her tripartite commitment to feminism, socialism, and individualism is illustrated, drawing on a wide range of her writings and statements between 1912 and 1937. In her crusade to celebrate and liberate the “variety and variability of women” Stella sought constantly to overthrow concepts of a monolithic female nature as well as to reject the Double Moral Standard: ‘normality’ to her was an instrument for the oppression of women. Consideration is also given to the wider influence of her ideas.     

Kosovo: Missed opportunities,lessons for the future

The growth in the number of 'small wars' has led to a proliferation of post-conflict reconstruction efforts. The experience in the Balkans with post-war reconstruction can provide a significant contribution to further learning, as much learning still needs to be done from the messy, poorly conceived, and chaotic manner in which the outside world stepped in and tried to help in the 1990s. Among the most important lessons that transpired is the need to include women fully in peace building. In the case of Kosovo, as elsewhere, the international effort was dominated by men, with little insight into or concern about addressing gender inequalities. This indifference in turn pervaded assistance programmes, with particularly damaging effects for local women.     

Justice for All? Factors Affecting Perceptions of Environmental and Ecological Injustice

Moving beyond the typical focus on individual injustices, we examine individual-level and contextual factors affecting perceptions of justice with regard to the environment. Specifically, we examine decision-making procedures pertaining to environmental resource use and harms across groups of people; the distribution of environmental harms; and the direct treatment of the natural environment (i.e., procedural environmental justice, distributive environmental injustice, and ecological injustice, respectively). To test our hypotheses, we use data from a survey administered to a cohort of first-year college students at a southeastern university. Results demonstrate that environmental identity and perceptions of the extent to which the university context encourages sustainability consistently enhance perceptions of all three types of justice. Other factors differentially affect each type of justice. We discuss the importance of the patterns that emerge for environmental and sustainability education and speculate on the implications of moving from thinking about (in)justice related to the environment as an individual issue to one of the collectivity.
