Effects of the organophosphorous pesticide, dimethoate, on cardiac and acetylcholinesterase (AChE) activity in the shore crab Carcinus maenas

The potential use of biochemical and physiological responses as biomarkers of organophosphate exposure and/or effect were assessed in the shore crab (Carcinus maenas). Male crabs were assigned to one of four dimethoate treatments (0, 0.5, 1.0 or 2.0 mg 1(-1)). Cardiac activity was measured non-invasively before and during dimethoate exposure using automated interpulse duration assessment. Heart rates decreased significantly in a concentration-dependent manner (p

Dropping the weight stigma: Nostalgia improves attitudes toward persons who are overweight

Weight stigma, a negative attitude toward persons who are overweight, can lead to emotional detriment (increased vulnerability to depression and anxiety, decreased self-esteem) and discriminatory practices (denial of employment, lower wages, refusal of job promotion or college admission, healthcare deprivation), which have increased dramatically in the United States over the past decade. We report two experiments that implicate nostalgia as a resource or strategy for weight stigma reduction. We hypothesized and found that nostalgia about an encounter with a person who is overweight improves attitudes toward the group "overweight." Undergraduates who recalled a nostalgic (vs. ordinary) interaction with an overweight person subsequently showed more positive outgroup attitudes. The effect of nostalgia on outgroup attitudes was mediated by greater inclusion of the outgroup in the self and increased outgroup trust (Experiments 1 and 2), as well as reduced intergroup anxiety and greater perceptions of a common ingroup identity (Experiment 2). The findings have interventional potential. (C) 2011 Elsevier Inc. All rights reserved.

Minding the Gap: Children with Disabilities and the United Nations Convention on the Rights of Persons with Disabilities

This chapter provides a critical assessment of the approach adopted by the United Nations Convention on the Rights of Persons with Disabilities (CRPD) towards children with disabilities and its implications for socializing States Parties to both ‘right’ and ‘rights’ behaviour. It discusses the ways in which ‘rights talk’ for children with disabilities, itself a relatively recent development in this context, has been predominantly needs based in its substantive content, and explores whether the exacerbated disadvantage experienced by children with disabilities as a result of the particular interaction between disability and childhood is effectively addressed and given due weight by the new Convention. The CRPD's provisions are discussed in the context of children with disabilities and their potential to provide effective redress assessed. The chapter concludes with some critical reflections on the extent to which the CRPD can really be understood as minding the gap for children with disabilities.

Development of a Broad-Specificity Monoclonal Antibody-Based Immunoaffinity Chromatography Cleanup for Organophosphorus Pesticide Determination in Environmental Samples

An immunoaffinity chromatographic (IAC) method for the selective extraction and concentration of 13 organophosphorus pesticides (OPs, including coumaphos, parathion, phoxim, quinalphos, dichlofenthion, triazophos, azinphos-ethyl, phosalone, isochlorthion, parathion-methyl, cyanophos, disulfoton, and phorate) prior to analysis by high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) was developed. The IAC column was prepared by covalently immobilizing a monoclonal antibody with broad specificity for OPs on CNBr-activated Sephrose 4B. The column capacity ranged from 884 to 2641 ng/mL of gel. The optimum elution solvent was 0.01 M phosphate-buffered saline containing 80% methanol. The breakthrough volume of the IAC column was found to be 400 mL. Recoveries of OPs from spiked environmental samples by IAC cleanup and HPLC-MS/MS analysis ranged from 60.2 to 107.1%, with a relative standard deviation below 11.1%. The limit of quantitation for 13 OPs ranged from 0.01 to 0.13 ng/mL (ng/g). The application of IAC cleanup coupled to HPLC-MS/MS in real environmental samples demonstrated the potential of this method for the determination of OP residues in environmental samples at trace levels.

Delaying Truth Recovery for Missing Persons

The fate of missing persons is a central issue in post-conflict societies facing truth recovery and human rights dilemmas. Despite widespread public sympathy towards relatives, societies emerging from conflict often defer the recovery of missing for decades. More paradoxically, in post-1974 Cyprus, the official authorities delayed unilateral exhumations of victims buried within cemeteries in their own jurisdiction. Analysis of official post-1974 discourse reveals a Greek-Cypriot consensus to emphasise the issue as one of Turkish aggression, thus downplaying in-group responsibilities and the legacy of intra-communal violence. We compare the experience of Cyprus with other post-conflict societies such as Spain, Northern Ireland, and Mozambique and explore the linkages between institutions and beliefs about transitional justice. We argue that elite consensus initiates and facilitates the transition to democracy but often leads to the institutionalization of groups opposing truth recovery even for in-group members.

An Enchanted Tool? Humanitarian Assistance and the ILC Draft Articles on the Protection of Persons in the Event of Disasters

Despite previous attempts at codification of international law regarding international responses to natural and human-made disasters, there is currently no binding international legal framework to regulate the provision of humanitarian assistance outside armed conflicts. Nevertheless, since the International Law Commission (ILC) included the protection of persons in the event of disasters on its programme of work in 2006, it has provisionally adopted eleven draft articles that have the potential to create binding obligations on states and humanitarian actors in disaster settings. Draft articles adopted include the definition of ‘a disaster’, the relationship of the draft articles to the international humanitarian law of armed conflict, recognition of the inherent dignity of the human person, and the duty of international cooperation. However, the final form of the draft articles has not been agreed. The Codification Division of the UN Office of Legal Affairs has proposed a framework convention format, which has seen support in the ILC and the UN General Assembly Sixth Committee. The overall aim of this article is to provide an analysis of the potential forms of international regulation open to the ILC and states in the context of humanitarian responses to disasters. However to avoid enchanting the ILC draft articles with unwarranted power, any examination of form requires an understanding of the substantive subject matter of the planned international regulation. The article therefore provides an overview of the international legal regulation of humanitarian assistance following natural and human-made disasters, and the ILC’s work to date on the topic. It then examines two key issues that remain to be addressed by the ILC and representatives of states in the UN General Assembly Sixth Committee. Drawing on the UN Guiding Principles on Internal Displacement, the development and implications of binding and non-binding international texts are examined, followed by an analysis of the suggested framework convention approach identified by the Special Rapporteur as a potential outcome of the ILC work.

Elements of A New Framework for the principle of Equal Treatment of persons in EC Law

In June and November 2000, the European Parliament and the Council adopted two Directives referring to ‘the principle of equal treatment irrespective of’ in their title, one relating to racial and ethnic origin, the other to disability, age, religion and belief or sexual orientation. A thorough reform of Directive 76/207/EEC on the principle of equal treatment for women and men in employment matters is pending between the European Parliament's second reading and adoption while this is written. Community secondary legislation on equal treatment of persons has thus expanded in scope and number of reasons which must not serve as starting points for differentiation. Does this signify progress in legal protection against personal discrimination? While not providing a ready answer, this article proposes an analytical framework to answer this question, concentrating on conceptions of equality in general and in particular on the problems multi-dimensional discrimination might pose for the law.
