Participatory risk assessment: a new approach for safer food in vulnerable African communities

Women play the major role in food supply in developing countries, but too often their ability to feed their families properly is compromised; the result is high levels of food-borne disease and consequent limited access to higher-value markets. We argue that risk-based approaches – current best practice for managing food safety in developed countries – require adaptation to the difficult context of informal markets. We suggest participatory research and gender analysis as boundary-spanning mechanisms, bringing communities and food-safety implementers together to analyse food-safety problems and develop workable solutions. Examples show how these methodologies can contribute to operationalising risk-based approaches in urban settings and to the development of a new approach to assessing and managing food safety in poor countries, which we call ‘participatory risk analysis’.     

Innovating Science Policy: Restructuring S&T Policy for the Twenty-first Century1

Over the next twenty years, accelerating scientific and technical developments will spawn immense changes to society that can be both crucially beneficial and tragically destructive. This trend, principally occurring outside of government control, is both helping the United States to improve defense and economic security and producing threats to national security. To deal with these increasingly technical issues, the nation's leadership needs to be armed with considerable scientific and technological acumen. Hence, the United States should explore the creation of a national security science and technology (S&T) strategy that improves: (1) scientific analysis available to decision makers; (2) understanding of the S&T needed to maintain national security; (3) coordination and collaboration among S&T providers; (4) control of dangerous technologies; (5) technology prioritization and acquisition processes; and (6) the dialog on enhancing the application of the products of private sector and foreign research for American national security purposes. Policies that address these issues will have to achieve the difficult balance between government and scientists’ influence over research and development (R&D). This article explores how to better deliver technical advice to high-level decision makers, as a means to better deal with emerging threats that are enabled by the rapid innovation and proliferation of scientific knowledge throughout the world.     

Sex-typed role in male adolescent sexual abuse survivors

Confusion and conflicts regarding sexual identity have been identified by clinicians as sequelae of sexual abuse in male adolescents. The empirical evidence supporting this assertion is limited, however. The purpose of this study was to examine the relationship between sexual abuse of male adolescents and their sexual self-concept in comparison to other clinical and nonclinical adolescent populations. The Bem Sex-Role Inventory (BSRI) was administered to 31 sexually abused male adolescents, 14 nonabused, psychiatrically treated male adolescents, and 35 nonabused, nonpsychiatric male adolescents. A significant difference in sex-typed roles was found between sexually abused male adolescents and nonabused, nonpsychiatric male adolescents.     

Collateral Damage: An Analysis of the Achievements and Unintended Consequences of Batterer Intervention Programs and Discourse

This paper reviews and critiques two prevailing program models for batterer intervention in order to highlight both their valuable achievements and attendant costs and consequences. We analyze these batterer intervention program models at 3 levels. First, we describe the historical development and basic program components of the intervention models. Second, we trace differences in the models to their grounding in different psychological assumptions and theories about behavior change, masculinity, and violence. Third, differences between the models are mapped onto contrasting approaches to the regulation of human deviance in the criminal justice and mental health systems. Based on this analysis, we conclude that further attention to structural and contextual factors, such as class, race, economic stress, and substance abuse in explanations of domestic violence is needed, together with alternative approaches to collaboration between victim advocates and batterer intervention providers.     

Mothers of children removed under a care order: outcomes and experiences

ABSTRACT

Focusing on accounts by women who have children taken into care, this paper reports on a socio-legal case study in England, investigating the life experiences of nine mothers, whose children have been made subject to care orders under the Children Act 1989. In particular it considers the women’s experiences of their relationships with their own mothers and places this within the context of the mothers’ own experiences of having their children taken into care. Drawing on free association narrative interviews, the study focuses on the mothers’ accounts of long-term harm that began in their childhoods, especially their experiences of their mothers’ own difficulties and of their experiences of harm. It highlights the impact of relationship difficulties between mother and child, and questions how the legal concepts of harm and reasonable parental care are defined and deployed. In conclusion, it demonstrates a need for the legal framework to address children’s experiences of harm in a more intergenerational and intersubjective way. It highlights a new approach, suggesting consideration of harm, reasonable parental care and welfare to involve an increased concentration on the welfare of mothers and the relationship between mother and child, akin to an intersubjective and intergenerational approach to harm.     

Development of a real-time method to detect DNA degradation in forensic samples

Abstract: Knowledge of the degradation state of evidentiary DNA samples would allow selection of the appropriate analysis method (standard short tandem repeats [STRs] vs. mini STRs vs. mtDNA). This article describes the development of a Plexor® technology/real‐time PCR DNA degradation detection assay, which uses a common forward primer and two reverse primers (different fluorophores) to generate two Alu amplicons (63 and 246 bp). This very sensitive assay was optimized for reaction volume, cycle number, anneal/extend time, and temperature. Using DNA samples degraded with DNaseI, the ratio of the concentration of the short amplicon to the concentration of the long amplicon (degradation ratio) was increased versus time of degradation. Experiments were performed on a variety of environmentally degraded samples (age, sunlight, heat) and with seven commonly encountered forensic inhibitors. The degradation ratio was found to predict the observed loss of larger STR loci seen in the analysis of comprised samples.     

Nano-scale composition of commercial white powders for development of latent fingerprints on adhesives

Titanium dioxide based powders are regularly used in the development of latent fingerprints on dark surfaces. For analysis of prints on adhesive tapes, the titanium dioxide can be suspended in a surfactant and used in the form of a powder suspension. Commercially available products, whilst having nominally similar composition, show varying levels of effectiveness of print development, with some powders adhering to the background as well as the print.X-ray fluorescence (XRF), analytical transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS) and laser particle sizing of the fingerprint powders show TiO₂ particles with a surrounding coating, tens of nanometres thick, consisting of Al and Si rich material, with traces of sodium and sulphur. Such aluminosilicates are commonly used as anti-caking agents and to aid adhesion or functionality of some fingerprint powders; however, the morphology, thickness, coverage and composition of the aluminosilicates are the primary differences between the white powder formulations and could be related to variation in the efficacy of print development.
