Externalizing Problem Behavior in Adolescence: Parenting Interacting With DAT1 and DRD4 Genes

This study extends previous gene‐by‐environment (G × E) research through design and methodological advances and examines alternative hypotheses of diathesis stress, vantage sensitivity, and differential susceptibility. In a sample of 984 adolescents and their parents, we examined whether effects of parental support, proactive, punitive, harsh punitive, and psychological control on externalizing problem behavior are moderated by adolescents' genotype for the dopamine transporter (DAT1) or receptor D4 (DRD4) gene. Results provided evidence for main effects of parenting behavior and DRD4, and multiple interaction effects of which one survived Bonferroni correction. Adolescents carrying a long DRD4 variant were more susceptible to the effects of parental proactive control on aggression, for better and for worse. Critical considerations were made regarding the complexity of G × E research.     

The displaced and dispossessed of Darfur: explaining the sources of a continuing state-led genocide

The millions of survivors who fled from attacks to Sudanese-controlled displacement camps and the refugee camps in Chad are the living ghosts of the Darfur genocide. The 1948 Genocide Convention incorporates extermination by mass killing and elimination through forced migration as two distinct elements of genocide. Genocide scholars and public discourse emphasize extermination by killing, but they give far less explanatory attention to the elimination processes that the Genocide Convention describes as 'deliberately inflicting on the group conditions of life calculated to bring about its physical destruction'. (Article II United Nations 1948.) In Darfur, understanding the latter processes requires theoretical attention to the history of food, water, and famine and detailed methodological attention to temporal processes of displacement. We demonstrate how intentional state-led attacks on food and water massively dislodged Black Africans in Darfur from February 2003 to August 2004. The political leadership of the Sudanese state dehumanized and forcibly displaced Black Africans from their homes in Darfur to camps where they largely remain, not only through mass killings and rapes, but also by destroying life-sustaining access to food and water, leading to the genocidal elimination of group life in this region.     

Between Civilizations: One Side of a Dialogue

In the present global context, the ‘problem’ of religion in relation to gender has become predominantly about the situation of Muslim women and what this indicates about the state of our civilization. Thus, in such incidents as the death of Aqsa Parvez (age 16) in late 2007 in Toronto, Canada, Muslim women's bodies, as many scholars have argued, become the battlegrounds which clearly demarcate the line between the civilized secular modern nation and premodern religious fundamentalisms. In this paper, I want to extend this critical work by bringing in an analysis of the second or ‘homegrown’ generation as it is in this context, I will argue that national anxieties about Canada's global status as a tolerant multicultural nation are most pronounced. Drawing on the work of Asad (2003), Mahmood (2006) and Brown (2006), I will outline how conceptions of tolerance and secularism operate through culture to produce a racialized distinction between the civilized, modern citizen and premodern fundamentalist groups in the making of Canada as a white settler multicultural nation. In order to illustrate this concretely, I will carry out a critical content analysis of representations of Aqsa Parvez's death in the media, representations which clearly demonstrate the contemporary operation of secularism and tolerance in relation to multiculturalism and its particular intensity as it pertains to second generation Muslims. In the conclusion, I want to reflect on how we might rethink our understanding of violence against Muslim women in order to destabilize this powerful binaristic framing which continues to secure a white settler hegemony of ‘multiculturalism within a bilingual framework’ even as it obscures the power relations through which it sustains a racial hierarchy.     

Food Security: An Ecological–Social Analysis to Promote Social Development

Coupled with the obesity epidemic, food insecurity presents a public health and social crisis. The United States' industrialized food system embodies an unsustainable network of production and unequal distribution of food creating threats to both the natural environment and human development. Ecological, economic, and social systems are interdependent and their relationships to food security are complex and dynamic. Social workers have a unique set of community practice knowledge and skills that can help communities achieve greater access to affordable, healthy food. Building interdisciplinary networks to change food policies and develop sustainable and equitable food systems can address food insecurity.     

A New Characterization and Estimation of the Zero–bias Bandwidth

It is well established that bandwidths exist that can yield an unbiased non–parametric kernel density estimate at points in particular regions (e.g. convex regions) of the underlying density. These zero–bias bandwidths have superior theoretical properties, including a 1/n convergence rate of the mean squared error. However, the explicit functional form of the zero–bias bandwidth has remained elusive. It is difficult to estimate these bandwidths and virtually impossible to achieve the higher–order rate in practice. This paper addresses these issues by taking a fundamentally different approach to the asymptotics of the kernel density estimator to derive a functional approximation to the zero–bias bandwidth. It develops a simple approximation algorithm that focuses on estimating these zero–bias bandwidths in the tails of densities where the convexity conditions favourable to the existence of the zerobias bandwidths are more natural. The estimated bandwidths yield density estimates with mean squared error that is O(n^–4/5), the same rate as the mean squared error of density estimates with other choices of local bandwidths. Simulation studies and an illustrative example with air pollution data show that these estimated zero–bias bandwidths outperform other global and local bandwidth estimators in estimating points in the tails of densities.     

Moving from sustainable management to sustainable governance of natural resources: The role of social learning processes in rural India,Bolivia and Mali

The present paper discusses a conceptual, methodological and practical framework within which the limitations of the conventional notion of natural resource management (NRM) can be overcome. NRM is understood as the application of scientific ecological knowledge to resource management. By including a consideration of the normative imperatives that arise from scientific ecological knowledge and submitting them to public scrutiny, ‘sustainable management of natural resources’ can be recontextualised as ‘sustainable governance of natural resources’. This in turn makes it possible to place the politically neutralising discourse of ‘management’ in a space for wider societal debate, in which the different actors involved can deliberate and negotiate the norms, rules and power relations related to natural resource use and sustainable development. The transformation of sustainable management into sustainable governance of natural resources can be conceptualised as a social learning process involving scientists, experts, politicians and local actors, and their corresponding scientific and non-scientific knowledges. The social learning process is the result of what Habermas has described as ‘communicative action’, in contrast to ‘strategic action’. Sustainable governance of natural resources thus requires a new space for communicative action aiming at shared, intersubjectively validated definitions of actual situations and the goals and means required for transforming current norms, rules and power relations in order to achieve sustainable development. Case studies from rural India, Bolivia and Mali explore the potentials and limitations for broadening communicative action through an intensification of social learning processes at the interface of local and external knowledge. Key factors that enable or hinder the transformation of sustainable management into sustainable governance of natural resources through social learning processes and communicative action are discussed.
