Detection of Acetone Processing of Castor Bean Mash for Forensic Investigation of Ricin Preparation Methods*

Abstract: Samples containing the toxic castor bean protein ricin have been recently seized in connection with biocriminal activity. Analytical methods that enable investigators to determine how the samples were prepared and to match seized samples to potential source materials are needed. One commonly described crude ricin preparation method is acetone extraction of crushed castor beans. Here, we describe the use of solid‐phase microextraction and headspace analysis to determine whether castor beans were processed by acetone extraction. We prepared acetone‐extracted castor bean mash, along with controls of unextracted mash and mash extracted with nonacetone organic solvents. Samples of acetone‐extracted mash and unextracted mash were stored in closed containers for up to 109 days at both room temperature and ?20°C, and in open containers at room temperature for up to 94 days. Acetone‐extracted bean mash could consistently be statistically distinguished from controls, even after storage in open containers for 94 days.     

Legitimacy is Not Authority

The two leading traditions of theorizing about democratic legitimacy are liberalism and deliberative democracy. Liberals typically claim that legitimacy consists in the consent of the governed, while deliberative democrats typically claim that legitimacy consists in the soundness of political procedures. Despite this difference, both traditions see the need for legitimacy as arising from the coercive enforcement of law and regard legitimacy as necessary for law to have normative authority. While I endorse the broad aims of these two traditions, I believe they both misunderstand the nature of legitimacy. In this essay I argue that the legitimacy of a law is neither necessary nor sufficient for its normative authority, and I argue further that the need for legitimacy in law arises regardless of whether the law is coercively enforced. I thus articulate a new understanding of the legitimacy and authority of law.     

Race,ethnicity, and prison disciplinary misconduct

It is well known that racial and ethnic minorities (both male and female) have felt the effect of increased incarceration more than Whites, and a large amount of prior research has investigated the factors that influence higher levels of inmate misconduct, including the influence of race/ethnicity. This body of research has produced mixed results. Using recent data from one of the largest state prison systems, this study sought to determine the level of racial and ethnic disparity in the commission of inmate misconduct. Results indicate that Black inmates were significantly more likely than other inmates to commit general rule violations, serious rule violations, and assaultive rule violations. Correlates of inmate misconduct and policy implications stemming from the findings are discussed.     

Population data at two short tandem repeat loci D2S1338 and D19S433 in the sample of multinational Bosnia and Herzegovina residents

POPULATION: We have analyzed the distribution of allele frequencies at two short tandem repeats loci (D2S1338 and D19S433) in a multinational sample of Bosnia and Herzegovina (B&H) residents. A total of 110 unrelated male and female individuals (Caucasians) from different regions of B&H were sampled for the analysis. We ensured that the sample reflected approximate proportional participation of the three main ethnic groups in the population of B&H (Bosniacs-Muslim [45%], Serbs [34%], Croats [21%]).     

Working with local NGOs: WaterAid's programme in Nepal

This article describes the evolution of WaterAid's programme of work in Nepal, based on the author's experiences while working as WaterAid's Representative Engineer in Nepal from 1987 to 1991. It examines how WaterAid's philosophy of working in partnership with local organisations was actually put into practice. Various problems and constraints are identified and discussed, and certain points are highlighted which may be of general interest to other external support agencies working in similar ways in other countries and sectors. The overall conclusion is that this programme represents a viable methodology for an international NGO to achieve useful results in supporting local NGOs working in development.
