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.  相似文献

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.  相似文献

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.  相似文献

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.  相似文献

Women in secure forensic mental health care require therapy and care that is responsive to their specific needs. Despite the policy recognition that women require a distinct service, evidence based practice is not available for this population. This review was undertaken in response to a clinical need within a medium secure unit in Glasgow that was experiencing high levels of challenging behaviour, in a female ward. The review aimed to identify effective strategies or interventions for the management of challenging behaviour in women in secure services and, therefore, improve practice and patient care. A synthesis of the findings from the 11 identified studies revealed variability in the approaches used to support women in forensic services, including: behavioural programmes; organisational change with a focus on staff training and support; medication; ECT and mechanical restraint. The challenging behaviours assessed included self-harm; physical and verbal aggression; suicide attempts and arson/fire setting. The majority of articles suggested some improvement in aspects of challenging behaviour, however this was limited by the lack of control groups and small sample sizes. Further investigation is required to find out whether interventions identified in this review can sustain a reduction in challenging behaviours in the long-term.  相似文献

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.  相似文献
