Rethinking Amnesties: Atrocity, Accountability And Impunity In Post-Conflict Societies.

The notion of accountability that is propagated in transitional justice often appears limited to demands for the prosecution and imprisonment of those who have been involved in serious human rights violations. Amnesties, widely understood as the absence of punishment for wrongdoing, are in turn considered by many scholars and activists as an example par excellence of the kind of Faustian pacts which are made in the name of political expediency in transitions from conflict. Drawing from a range of interdisciplinary literature, as well as research completed by the authors in a number of societies with a violent past, this paper uses amnesties as a case-study to argue for a more rounded interrogation of the notion of accountability in transitional justice. The paper charts the various forms of intersecting accountability which both shape and delimit amnesties at key ‘moments’ concerning their remit, introduction and operation. The paper concludes that the legalistic view of amnesties as equating to impunity and retribution as accountability is inaccurate and misleading. It argues that a broader perspective of accountability speaks directly to the capacity for amnesties to play a more constructive role in post conflict justice and peacemaking.

Gross anatomy and positional homology of gills, gonopores, and nephridiopores in “basal” living chitons (Polyplacophora: Lepidopleurina)

Traditional shell characters are insufficient to differentiate taxa within the polyplacophoran order Lepidopleurida. Additional morphological character sets from soft anatomy (e.g., gamete morphology, gill arrangement, and locations of gonopores and nephidiopores) have previously been described from only a small number of taxa. This study reports for the first time, positions of the gonopores and nephridiopores for 17 species in the Lepidopleurina. The position of both types of pores on the longitudinal body axis varies within a generalized range of the posterior third of the body; however, the separation between the pores as a proportion of the specimen’s foot length varies from 3.7% to 17% in different species. Positions of pores relative to the serial gills are also variable within species, and future studies may require a new descriptive basis in order to resolve positional homology. The order Lepidopleurida occupies a critical position with respect to understanding larger-scale patterns in polyplacophoran (and molluscan) evolution.

The costs of bearing arms and armour in the hermit crab Pagurus bernhardus

Hermit crabs use empty gastropod shells as protective armour and enlarged chelipeds as signals and weapons. However, carrying armour and arms may impose energy costs that result in increased lactate and hence potential fatigue and there may be consequent effects on general activity. We investigated whether variation in shell and cheliped size influences lactate levels in hermit crabs. Lactate was positively related to residual cheliped size for both sexes and was higher in males than females; when we controlled for body size, the former had larger chelipeds. Shell weight unexpectedly had no effect on lactate but crabs in small shells had high lactate, possibly because of reduced ability to maintain a respiratory current. The size of natural shells had no effect on activity but the addition of food odour increased locomotion. However, activity was not related to lactate. We conclude that possession of larger chelipeds than expected for body size imposes significant costs and may limit development of sexual dimorphism.

Self-Care, the Body and Identity: The Non-Abelist Consumer Perspective

Consumers confined to the home due to disability or long term illness are the subjects of this study. Home confined consumers are not subject to the public gaze but are nevertheless just as conscious of idealised conceptions of what constitutes a normalised body and strive to attain this by means of highly disciplined body self-care practices. This paper examines their consumption experiences and finds that they strive to create a disciplined approach to inner and outer body maintenance. They do so in order to maintain and develop self-identity, and even the survival of the self in their self-created marketplaces.

A proteomic analysis of thioacetamide-induced hepatotoxicity and cirrhosis in rat livers

Thioacetamide (TAA) administration is an established technique for generating rat models of liver fibrosis and cirrhosis. Oxidative stress is believed to be involved as TAA-induced liver fibrosis is initiated by thioacetamide S-oxide, which is derived from the biotransformation of TAA by the microsomal flavine-adenine dinucleotide (FAD)-containing monooxygense (FMO) and cytochrome P450 systems. A two-dimensional gel electrophoresis-mass spectrometry approach was applied to analyze the protein profiles of livers of rats administered with sublethal doses of TAA for 3, 6 and 10 weeks respectively. With this approach, 59 protein spots whose expression levels changed significantly upon TAA administration were identified, including three novel proteins. These proteins were then sorted according to their common biochemical properties and functions, so that pathways involved in the pathogenesis of rat liver fibrosis due to TAA-induced toxicity could be elucidated. As a result, it was found that TAA-administration down-regulated the enzymes of the primary metabolic pathways such as fatty acid beta-oxidation, branched chain amino acids and methionine breakdown. This phenomenon is suggestive of the depletion of succinyl-CoA which affects heme and iron metabolism. Up-regulated proteins, on the other hand, are related to oxidative stress and lipid peroxidation. Finally, these proteomics data and the data obtained from the scientific literature were integrated into an

Apoptosis and chemotherapy in bladder cancer in bladder cancer

Purpose: To discuss the role of apoptosis, gene directed self-destruction of a cell, in the response of transitional cell carcinoma of the bladder cells to chemotherapy. Methods: A directed MEDLINE literature search of apoptosis, bladder cancer and chemotherapy was performed to extract the relevant information, which was reviewed. The characteristics of apoptotic cells were defined and the methods in common use to detect these traits were described. The role of the key mediators of the apoptotic process in bladder cancer is discussed in the context of chemosensitivity and stage of disease. The importance of induction of apoptosis post chemotherapy is highlighted. Results: On stimulus by appropriate external or internal signals, a cell may alter the expression of genes coding for proteins associated with the apoptotic process. The development of apoptosis depends on the balance between pro- and anti- apoptotic proteins. Key alterations in genes and proteins related to apoptosis within bladder cancer result in a shift away from an ability to undergo apoptosis towards a cell with increased survival properties that is chemoresistant. Conclusions: Much current research in bladder cancer is aimed at restoring chemosensitivity by shifting the balance in a cell towards a pro-apoptotic phenotype. Successful translation of this work into clinical practice may improve survival in patients in whom prognosis is currently poor.

Association of impulsivity with sleep duration and insomnia in an employee population

Clinical studies have linked impulsivity and insomnia in patients, but little is known about this association in non-clinical settings. This study examined whether impulsive temperament is associated with sleep duration and insomnia complaints in a large cohort of hospital employees (535 men and 4014 women). Linear regression models were related to prospective data from two surveys conducted in 1998 and 2000. Adjustments were made for age, marital status, education, shift work, smoking, alcohol consumption, body mass index, physical activity, minor psychiatric morbidity, social support, somatic disease, depression and other psychiatric disease in 1998. In men, higher impulsivity predicted shorter sleep duration and waking up several times per night independent of baseline characteristics. In women, higher impulsivity predicted having difficulty falling asleep and waking up feeling tired after the usual amount of sleep after adjustment for most of covariates. However, these associations turned out to be non-significant after adjustment for somatic and psychiatric disease. These results support the hypothesis that impulsive temperament could be a risk factor for insomnia in men. (c) 2007 Elsevier Ltd. All rights reserved.

Residential consumption of gas and electricity in the U.S.: The role of prices and income

We study the residential demand for electricity and gas, working with nationwide household-level data that cover recent years, namely 1997-2007. Our dataset is a mixed panel/multi-year cross-sections of dwellings/households in the 50 largest metropolitan areas in the United States as of 2008. We estimate static and dynamic models of electricity and gas demand. We find strong household response to energy prices, both in the short and long term. From the static models, we get estimates of the own price elasticity of electricity demand in the -0.860 to -0.667 range, while the own price elasticity of gas demand is -0.693 to -0.566. These results are robust to a variety of checks. Contrary to earlier literature (Metcalf and Hassett, 1999; Reiss and White, 2005), we find no evidence of significantly different elasticities across households with electric and gas heat. The price elasticity of electricity demand declines with income, but the magnitude of this effect is small. These results are in sharp contrast to much of the literature on residential energy consumption in the United States, and with the figures used in current government agency practice. Our results suggest that there might be greater potential for policies which affect energy price than may have been previously appreciated. (C) 2011 Elsevier B.V. All rights reserved.

Class and Performance in the Age of Global Capitalism

This article addresses the relative absence of class-based analysis in theatre and performance studies, and suggests the reconfiguration of class as performance rather than as it is traditionally conceived as an identity predicated solely on economic stratification. It engages with the occlusion of class by the ascendancy of identity politics based on race, gender and sexuality and its attendant theoretical counterparts in deconstruction and post-structuralism, which became axiomatic as they displaced earlier methodologies to become hegemonic in the arts and humanities. The article proceeds to an assessment of the development of sociological approaches to theatre, particularly the legacy of Raymond Williams and Pierre Bourdieu. The argument concludes with the application of an approach which reconfigures class as performance to the production of Declan Hughes's play Shiver of 2003, which dramatizes the consequences of the dot.com bubble of the late 1990s for ambitious members of the Irish middle class.

Challenges of UK/Irish Contractors Regarding Material Management and Logistics in Confined Site Construction

The aim of this paper is to identify the various managerial issues encountered by UK/Irish contractors in the management of materials in confined urban construction sites. Through extensive literature review, detailed interviews, case studies, cognitive mapping, causal loop diagrams, questionnaire survey and documenting severity indices, a comprehensive insight into the materials management concerns within a confined construction site environment is envisaged and portrayed. The leading issues highlighted are: that contractors’ material spatial requirements exceed available space, it is difficult to coordinate the storage of materials in line with the programme, location of the site entrance makes delivery of materials particularly difficult, it is difficult to store materials on-site due to the lack of space, and difficult to coordinate the storage requirements of the various sub-contractors. With the continued development of confined urban centres and the increasing high cost of materials, any marginal savings made on-site would translate into significant monetary savings at project completion. Such savings would give developers a distinct competitive advantage in this challenging economic climate. As on-site management professionals successfully identify, acknowledge and counteract the numerous issues illustrated, the successful management of materials on a confined urban construction site becomes attainable.

Critical factors affecting management of site operatives and personal in confined construction site

The aim of this paper is to identify and classify the numerous managerial issues encountered in the management of personnel in confined site construction. For the purpose of this research, a confined construction site is defined as a site where permanent works fit the site footprint, extending to levels above and/or below ground level, leaving spatial restrictions for other operations (e.g. plant and material movements, materials storage and temporary accommodation etc.) and require effective resource co-ordination beyond normal on-site management input. A literature review and analysis, case studies incorporating interviews and focus groups along with a questionnaire survey were used in order to gain a comprehensive insight into the issues in the management of personnel in a confined construction site environment. The following are the top five leading issues highlighted in the management of personnel in confined site construction; (1) Accidents due to an untidy site, (2) One contractor holding up another because of the lack of space, (3) A risk to personnel because of vehicular traffic on-site, (4) Difficult to facilitate several contractors at one work location, and (5) Numerous personnel working within the one space. In today’s modern environment, spatial restrictions are quickly becoming the norm in the industry. Therefore, the management of personnel on-site becomes progressively more difficult with the decrease in available space on-site. Where such environments exist, acknowledging the numerous issues highlighted above, aids site management in the supervision and co-ordination of personnel on-site, thus reducing accidents, increasing productivity and increase profit margins, in spatially restricted environments. As on-site management professionals successfully identify, acknowledge and counteract the numerous issues illustrated, the successful management of personnel on a confined construction site is achievable. By identifying the numerous issues, on-site management can proactively mitigate such issues through adopting counteractive measures and through successful identification of the traits identified.
