Crocodile crimes: people versus wildlife and the politics of postcolonial conservation on Lake Kariba, Zimbabwe

This article is about the politics of conservation in postcolonial Southern Africa. It focuses on the process and consequences of redefining the Nile crocodile as an endangered species and explores the linked local and international, commercial and conservationist interests that allowed the animal to re-establish itself in state-protected waterways in colonial and postcolonial contexts. It investigates the effects of the animal's successful re-accommodation by examining conflicts between crocodiles and the fishing communities sharing space on Lake Kariba, Zimbabwe. Fishermen's hostile representations of the animal emphasize competition for fish, harassment, fear, loss of assets and loss of life. Their fear of crocodiles is heightened by the animal's entanglement in local social life, through its association with witchcraft. The article emphasizes the importance of considering both hegemonic and marginalized ideas about animals in the light of the material interactions, relations of power and historical contexts that shape them. Understanding the attitudes and circumstances of the local communities who bear the physical and economic costs of living with dangerous animals is important-it threatens the future of conservation programmes and reveals the potential for significant abuses to accompany the conservation of wildlife in postcolonial contexts. © 2004 Elsevier Ltd.

The geography of tyranny and despair: development indicators and the hypothesis of genetic inevitability of national inequality

Development geography has long sought to understand why inequalities exist and the best ways to address them. Dependency theory sets out an historical rationale for under development based on colonialism and a legacy of developed core and under-developed periphery. Race is relevant in this theory only insofar that Europeans are white and the places they colonised were occupied by people with darker skin colour. There are no innate biological reasons why it happened in that order. However, a new theory for national inequalities proposed by Lynn and Vanhanen in a series of publications makes the case that poorer countries have that status because of a poorer genetic stock rather than an accident of history. They argue that IQ has a genetic basis and IQ is linked to ability. Thus races with a poorer IQ have less ability, and thus national IQ can be positively correlated with performance as measured by an indicator like GDP/capita. Their thesis is one of despair, as little can be done to improve genetic stock significantly other than a programme of eugenics. This paper summarises and critiques the Lynn and Vanhanen hypothesis and the assumptions upon which it is based, and uses this analysis to show how a human desire to simplify in order to manage can be dangerous in development geography. While the attention may naturally be focused on the 'national IQ' variables as a proxy measure of 'innate ability', the assumption of GDP per capita as an indicator of 'success' and 'achievement' is far more readily accepted without criticism. The paper makes the case that the current vogue for indicators, indices and cause-effect can be tyrannical.

Attenuating mutations in the influenza virus genome which may increase the safety of vaccine production

Influenza virus epidemics occur on an annual basis and cause severe disease in the very young and old. The vaccine administered to high-risk groups is generated by amplifying reassortant viruses, with chronologically relevant viral surface antigens, in eggs. Every 20 years or so, influenza pandemics occur causing widespread fatality in all age groups. These viruses display novel viral surface antigens acquired from a zoonotic source, and vaccination against them poses new issues since production of large amounts of a respiratory virus containing novel surface antigens could be dangerous for those involved in manufacture. To minimise risks, it is advisable to use a virus whose genetic backbone is highly attenuated in man. Traditionally, the A/PR/8/34 strain of virus is used, however, the genetic basis of its attenuation is unclear. Cold-adapted (CA) strains of the influenza virus are all based on the H2N2 subtype, itself a virus with pandemic potential, and again the genetic basis of temperature sensitivity is not yet established. Reverse genetics technology allows us to engineer designer influenza viruses to order. Using this technology, we have been investigating mutations in several different gene segments to effectively attenuate potential vaccine strains allowing the safe production of vaccine to protect against the next pandemic.

A little learning is a dangerous thing: an experimental demonstration of ignorance-driven inference

Studies of ignorance-driven decision making have been employed to analyse when ignorance should prove advantageous on theoretical grounds or else they have been employed to examine whether human behaviour is consistent with an ignorance-driven inference strategy (e. g., the recognition heuristic). In the current study we examine whether-under conditions where such inferences might be expected-the advantages that theoretical analyses predict are evident in human performance data. A single experiment shows that, when asked to make relative wealth judgements, participants reliably use recognition as a basis for their judgements. Their wealth judgements under these conditions are reliably more accurate when some of the target names are unknown than when participants recognize all of the names (a "less-is-more effect"). These results are consistent across a number of variations: the number of options given to participants and the nature of the wealth judgement. A basic model of recognition-based inference predicts these effects.

Parallel performance and scalability experiments with the Danish Eulerian Model on the EPCC supercomputers

The Danish Eulerian Model (DEM) is a powerful air pollution model, designed to calculate the concentrations of various dangerous species over a large geographical region (e.g. Europe). It takes into account the main physical and chemical processes between these species, the actual meteorological conditions, emissions, etc.. This is a huge computational task and requires significant resources of storage and CPU time. Parallel computing is essential for the efficient practical use of the model. Some efficient parallel versions of the model were created over the past several years. A suitable parallel version of DEM by using the Message Passing Interface library (AIPI) was implemented on two powerful supercomputers of the EPCC - Edinburgh, available via the HPC-Europa programme for transnational access to research infrastructures in EC: a Sun Fire E15K and an IBM HPCx cluster. Although the implementation is in principal, the same for both supercomputers, few modifications had to be done for successful porting of the code on the IBM HPCx cluster. Performance analysis and parallel optimization was done next. Results from bench marking experiments will be presented in this paper. Another set of experiments was carried out in order to investigate the sensitivity of the model to variation of some chemical rate constants in the chemical submodel. Certain modifications of the code were necessary to be done in accordance with this task. The obtained results will be used for further sensitivity analysis Studies by using Monte Carlo simulation.

D. H. Lawrence and the publication of Look! We Have Come Through!

In 1917 D.H. Lawrence's whole outlook on the social and cultural environment of his country was embodied in his attitude towards the literary marketplace. The suppression of The Rainbow in 1915 and his opposition to the war contributed to his feeling of detachment from what he called ‘the bourgeois world, the world which controls press, publication and all’. Presenting new archival evidence, this article examines the publishing history of the poetry volume Look! We Have Come Through, issued by Chatto & Windus in 1917. Closer examination of the motives of the individual editors involved in the production of the volume reveals why Lawrence was required to make changes to his text but also why the firm were eager to publish a volume that was to have little commercial impact. Issued at a critical moment in Lawrence's relationship with the marketplace, and in the history of literary modernism, the episode shows how, in spite of general hostility to his work, there were forces in the mainstream publishing market that were keen to embrace modern literary forms and take risks with the work of authors whose subject-matter was challenging and potentially dangerous.

Return of the 'Angry Woman': authenticating female physical action in contemporary cinema

In 1999, Elizabeth Hills pointed up the challenges that physically active women on film still posed, in cultural terms, and in relation to certain branches of feminist theory . Since then, a remarkable number of emphatically active female heroes have appeared on screen, from 'Charlie’s Angels' to 'Resident Evil', 'Aeon Flux', and the 'Matrix' and 'X-Men' trilogies. Nevertheless, in a contemporary Western culture frequently characterised as postfeminist, these seem to be the ‘acceptable face’ – and body – of female empowerment: predominantly white, heterosexual, often scantily clad, with the traditional hero’s toughness and resolve re-imagined in terms of gender-biased notions of decorum: grace and dignity alongside perfect hair and make-up, and a body that does not display unsightly markers of physical exertion. The homogeneity of these representations is worth investigating in relation to critical claims that valorise such air-brushed, high-kicking 'action babes' for their combination of sexiness and strength, and the feminist and postfeminist discourses that are refracted through such readings. Indeed, this arguably ‘safe’ set of depictions, dovetailing so neatly with certain postfeminist notions of ‘having it all’, suppresses particular kinds of spectacles in relation to the active female body: images of physical stress and extension, biological consequences of violence and dangerous motivations are all absent. I argue that the untidy female exertions refused in popular “action babe” representations are now erupting into view in a number of other contemporaneous movies – 'Kill Bill' Vols 1 & 2, 'Monster', and 'Hard Candy' – that mark the return of that which is repressed in the mainstream vision of female power – that is, a more viscerally realistic physicality, rage and aggression. As such, these films engage directly with the issue of how to represent violent female agency. This chapter explores what is at stake at a representational level and in terms of spectatorial processes of identification in the return of this particularly visceral rendering of the female avenger.

Last charge of the knights? Iraq, Afghanistan and the special relationship

At the heart of the ‘special relationship’ ideology, there is supposed to be a grand bargain. In exchange for paying the ‘blood price’ as America's ally, Britain will be rewarded with exceptional influence over American foreign policy and its strategic behaviour. Soldiers and statesman continue to articulate this idea. Since 9/11, the notion of Britain playing ‘Greece’ to America's ‘Rome’ gained new life thanks to Anglophiles on both sides of the Atlantic. One potent version of this ideology was that the more seasoned British would teach Americans how to fight ‘small wars’ in Iraq and Afghanistan, thereby bolstering their role as tutor to the superpower. Britain does derive benefits from the Anglo-American alliance and has made momentous contributions to the wars in Afghanistan and Iraq. Yet British solidarity and sacrifices have not purchased special influence in Washington. This is partly due to Atlanticist ideology, which sets Britain unrealistic standards by which it is judged, and partly because the notion of ‘special influence’ is misleading as it loses sight of the complexities of American policy-making. The overall result of expeditionary wars has been to strain British credibility in American eyes and to display its lack of consistent influence both over high policy and the design and execution of US military campaigns. While there may be good arguments in favour of the UK continuing its efforts in Afghanistan, the notion that the war fortifies Britain's vicarious world status is a dangerous illusion that leads to repeated overstretch and disappointment. Now that Britain is in the foothills of a strategic defence review, it is important that the British abandon this false consciousness.
