IMPLEMENTATION WITH STATE DEPENDENT FEASIBLE SETS AND PREFERENCES: A RENEGOTIATION APPROACH

In this paper we present a model of implementation based on the idea that agents renegotiate unfeasible allocations. We characterize the maximal set of Social Choice Correspondences that can be implemented in Nash Equilibrium with a class of renegotiation functions that do not reward agents for unfeasibilities. This result is used to study the possibility of implementing the Walrasian Correspondence in exchange economies and several axiomatic solutions to problems of bargaining and bankruptcy.

Handedness as a marker of cerebral lateralization in children with and without autism

We employed a multiple case studies approach to investigate lateralization of hand actions in typically and atypically developing children between 4 and 5 years of age. We report on a detailed set of over 1200 hand actions made by four typically developing boys and four boys with autism. Participants were assessed for unimanual hand actions to both objects and the self (self-directed behaviors). Individual and group analyses suggest that typically developing children have a right hand dominance for hand actions to objects and a left hand dominance for hand actions for self-directed behaviors, revealing a possible dissociation for functional specialization of the left and right hemispheres respectively. Children with autism demonstrated mixed-handedness for both target conditions, consistent with the hypothesis that there is reduced cerebral specialization in these children. The findings are consistent with the view that observed lateralized motor action can serve as an indirect behavioral marker for evidence of cerebral lateralization

The continuing rise of contact dermatitis, part 1: the academic discipline

This article describes the history and development of contact dermatitis as an academic discipline, from early observations documented in ancient Egypt and Greece, to the current medical specialization we know today. Given its essential role in clinical diagnosis, the history of patch testing is also discussed, including the pioneering work of Stdeler, von Hebra, Jadassohn, and others. The historical development of some international societies for contact dermatitis is provided, along with some discussion on bibliometric performance in this field. Overall, it can be seen that from humble beginnings, contact dermatitis is now thriving as a specialized field in clinical dermatology

Gender, forests and famine in nineteenth century Chotanagpur, India

This paper examines the links between deforestation and famine in the context of the late-19th-century food crisis in Chotanagpur. It attempts to understand the phenomenon famine as a gendered one, and explores the cultural and gendered meanings of hunger. In doing so it looks at the symbolism of the landscape and the gendering of it by local communities in Chotanagpur

The historical development of academic journals in occupational medicine, 1901-2009

Academic journals in a specialist field provide an interesting historical record of its development and progression over time. This article describes the evolution of some major international journals of occupational medicine, including some historical background on their editorial board. As North America, the United Kingdom, and Northern Europe are known to have the highest contribution to scientific production, it was considered appropriate to investigate the main occupational medicine periodicals in these regions. Given the remarkable improvements in Japanese occupational health following the Second World War, it was also considered worthwhile to investigate the two English-language journals of occupational medicine from this country
