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.     

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.     

Contemporary Psychoanalysis and Critical Theory: A New Synthesis

ABSTRACT

Critical Theory and contemporary psychoanalytic perspectives share many compatibilities in offering a constructive critique of society. Psychoanalysis teaches us that whatever values and ideals societies adopt, they are always mediated through unconscious psychic processes that condition the collective in both positive and negative ways, and in terms of relations of recognition and patterns of social justice. Contemporary critical theory may benefit from engaging post-classical and current trends in psychoanalytic thought that have direct bearing on the ways we conceive of and observe how individuals operate within social collectives. In particular, Axel Honneth relies on psychoanalytic sources that are dated. Critical theory would profit from engaging post-object relations schools such as self psychology, analytical psychology, psychoanalytic intersubjectivity theory, relationality, and contemporary attachment theory that are more nuanced yet can supplement Winnicottian perspectives. Implications for contemporary theory need to reflect upon how the psychosocial matrix of self and society both facilitate and hinder optimal social arrangements and fabrics of justice as it takes up the question of normativity. It is within this context that I hope to introduce contemporary psychoanalytic paradigms that move beyond classical models yet complement redirecting shifts in emphasis both psychoanalysis and Critical Theory attempt to accomplish. I suggest that an applied psychoanalytic explication on social phenomenology can expand the interpretive depth and breadth of human relations and open up a permissible space for interdisciplinary discourse. Here new vistas emerge for a proposed synthesis between the two schools of thought.     

Labour and Its Discontents: The Consequences of Orthodox Reform in Venezuela and Mexico

The negative impacts of orthodox liberalisation policies on labour in Venezuela and Mexico were representative of outcomes elsewhere in Latin America. Untheorised increases in precarious informal work, unemployment, and emigration as well as a growing breech between wages and productivity followed trade, capital, and labour market reforms and the prescribed macro stabilisation policies. Orthodox reforms in both countries paradoxically facilitated market failures given the forms or modes taken by foreign direct investment (FDI), which introduced ever more increasing scale economies with their attendant information imperfections. In addition, the growing competition from tradeable goods faced by domestic producers in both countries and the decision to buy rather than make technologies by way of FDI undermined job creation and induced inter-sectoral flows toward service sector and informal work.
