Protecting civilians from conflict and atrocities has become a major focus of governments, the UN, and activists. Yet peace operations—the main policy instrument for directly shielding civilians from violence—vary widely in how well they are designed to do so. One much-maligned problem is a gap between a force's ambitions to protect civilians and its physical resources for doing so. Missions plagued by these ambitions–resources gaps gesture toward protecting civilians but are not designed to do so effectively. They can also worsen civilian suffering. This article explores the politics behind these gaps, focusing on the role of powerful states—especially major Western democracies—in creating and facilitating them. It argues that ambitions–resources gaps represent a form of organized hypocrisy that helps political leaders balance competing normative and material pressures to protect civilians while limiting costs and risks. Case studies of France's Operation Turquoise in Rwanda and US support for the African Union Mission in Sudan (AMIS) in Darfur support the argument.  相似文献

Two of the formal-stage experiments of Piaget and Inhelder, selected largely for their closeness to the concepts defining the stage, were replicated with groups of average and gifted adolescents. This report describes the relevant Piagetian concepts (formal stage, concrete stage) in context, gives the methods and findings of this study, and concludes with a section discussing implications and making some reformulations which generally support but significantly qualify some of the central themes of the Piaget-Inhelder work. Fully developed formal-stage thinking emerges as far from commonplace among normal or average adolescents (by marked contrast with the impression created by the Piaget-Inhelder text, which chooses to report no middle or older adolescents who function at less than fully formal levels). In this respect, the formal stage differs appreciably from the earlier Piagetian stages, and early adolescence emerges as the age for which a single path model of cognitive development becomes seriously inadequate and a more complex model becomes essential. Formal-stage thinking seems best conceptualized, like most other aspects of psychological maturity, as a potentiality only partially attained by most and fully attained only by some.This work has been supported by NIMH Research Career Development Award K3-MH-18, 701.Clinical Assistant Professor of Psychiatry, AECM.

This article discusses how legal rights-based discourse could inform the response of Australian State and federal governments to the increasing prevalence of childhood obesity. The authors contend that the principles in the United Nations Convention on the Rights of the Child (a treaty which has been ratified but not implemented) are capable of providing a basis for a legislative program to prevent childhood obesity. It is argued that an approach to legislation which is grounded on the basis of children's rights would require that there be restrictions on advertising food to children. The authors set out specific proposals for legislative reforms which the federal Parliament could enact to implement the Convention so as to restrict advertising to children. The scope of the discussion is then expanded to consider the implications of rights-based discourse in broader public health contexts.  相似文献

Forensic laboratories are often faced with cases in which methamphetamine hydrochloride‐mixed blood is unable to be identified as human blood by immunochromatography against human hemoglobin A0. The application of mRNA expression analysis to samples that showed a false‐negative with immunochromatography was investigated as an alternative approach that did not depend on the antigen–antibody reaction. Real‐time PCR was used to examine the expression levels of blood markers such as glycophorin A, spectrin beta, and hemoglobin beta. Hemoglobin beta was the only marker that was specifically detected in blood, while glycophorin A was useful for determining human specificity. Hemoglobin beta showed good detection sensitivity and was detectable in 37‐year‐old blood stains. Hemoglobin beta was exclusively detectable in methamphetamine hydrochloride‐mixed blood stains. Detergents and disinfectants did not significantly influence mRNA markers. The proposed mRNA expression analysis was suitable for human blood identification as an alternative method to immunochromatography.  相似文献
