    Overview study of Space Power Technologies for the advanced energetics program

    Get PDF
    Space power technologies are reviewed to determine the state-of-the-art and to identify advanced or novel concepts which promise large increases in performance. The potential for incresed performance is judged relative to benchmarks based on technologies which have been flight tested. Space power technology concepts selected for their potentially high performance are prioritized in a list of R & D topical recommendations for the NASA program on Advanced Energetics. The technology categories studied are solar collection, nuclear power sources, energy conversion, energy storage, power transmission, and power processing. The emphasis is on electric power generation in space for satellite on board electric power, for electric propulsion, or for beamed power to spacecraft. Generic mission categories such as low Earth orbit missions and geosynchronous orbit missions are used to distinguish general requirements placed on the performance of power conversion technology. Each space power technology is judged on its own merits without reference to specific missions or power systems. Recommendations include 31 space power concepts which span the entire collection of technology categories studied and represent the critical technologies needed for higher power, lighter weight, more efficient power conversion in space

    'An Apotheosis of Well-Being': Durkheim on austerity and double-dip recessions

    Get PDF
    This article is an attempt to contribute a view on the economic crisis from classical sociology, a voice often missing from the sociological response to the crisis. The work of Émile Durkheim provides a unique perspective here centred on morality and inequality produced in a historical context akin to our neoliberal times. It is argued there are four key points to take from Durkheim’s work. Firstly, that the initial credit crunch can be more fully understood with reference to the economic anomie which Durkheim sees as ‘chronic’ in a time of marketization. Secondly, that this creates an antagonistic relationship between a supposedly self-dependent rich and lazy poor. Thirdly, this conception of self-dependency and individual initiative makes any attempt to regulate the economy akin to sacrilege. Finally, the state is unwilling to intervene due to the emergence of ‘pseudo-democracies’. Therefore, Durkheim’s theory accounts for the initial crisis, austerity and double-dip recessions in a sociological framework. The article concludes by returning to the centrality of morality to the crisis for Durkheim and highlighting the omission of this in contemporary debates

    Review Essay: Biopolitics 2.0 – Reclaiming the Power of Life in the Anthropocene

    Get PDF
    Biopolitics was once the preserve of critical Foucauldian-influenced theorists. This is no longer the case. The rise of new materialisms, networked and object-oriented ontologies and demands for the ‘renaturalization of politics’ (Grosz, 2011; Sharp, 2011) have turned the political into the biopolitical in much of radical contemporary political theory. Here, the biopolitical is often in tension with the Foucauldian discourses of the last few decades, affirming alternative possibilities rather than merely critiquing regimes of power (Malabou, 2008; Kirby, 2011; Taussig, 2018). One factor in this shift has been the impact of anthropogenic climate change and global warming on the contemporary political imagination, increasingly refracted through conceptualizations of the Anthropocene (Tsing, 2015; Cohen et al, 2016; Chandler, 2018). A second factor has been that the life sciences no longer appear to support understandings of deterministic differences but rather to cast evolution in sympoietic and entangled ways, making biology appear as no longer essentialising but as increasingly importable into politics, in ways which disrupt modernist or liberal conceptions of the culture/nature divide (Haraway, 2016). Two important but very different engagements, which reflect these affirmative readings of biopolitics, are reviewed here, from the fields of postcolonial literature and gender and race in international politics

    Nigerian scam e-mails and the charms of capital

    Get PDF
    So-called '419' or 'advance-fee' e-mail frauds have proved remarkably successful. Global losses to these scams are believed to run to billions of dollars. Although it can be assumed that the promise of personal gain which these e-mails hold out is part of what motivates victims, there is more than greed at issue here. How is it that the seemingly incredible offers given in these unsolicited messages can find an audience willing to treat them as credible? The essay offers a speculative thesis in answer to this question. Firstly, it is argued, these scams are adept at exploiting common presuppositions in British and American culture regarding Africa and the relationships that are assumed to exist between their nations and those in the global south. Secondly, part of the appeal of these e-mails lies in the fact that they appear to reveal the processes by which wealth is created and distributed in the global economy. They thus speak to their readers’ attempts to map or conceptualise the otherwise inscrutable processes of that economy. In the conclusion the essay looks at the contradictions in the official state response to this phenomena

    Counterparts: Clothing, value and the sites of otherness in Panapompom ethnographic encounters

    Get PDF
    This is an Author's Accepted Manuscript of an article published in Anthropological Forum, 18(1), 17-35, 2008 [copyright Taylor & Francis], available online at: http://www.tandfonline.com/10.1080/00664670701858927.Panapompom people living in the western Louisiade Archipelago of Milne Bay Province, Papua New Guinea, see their clothes as indices of their perceived poverty. ‘Development’ as a valued form of social life appears as images that attach only loosely to the people employing them. They nevertheless hold Panapompom people to account as subjects to a voice and gaze that is located in the imagery they strive to present: their clothes. This predicament strains anthropological approaches to the study of Melanesia that subsist on strict alterity, because native self‐judgments are located ‘at home’ for the ethnographer. In this article, I develop the notion of the counterpart as a means to explore these forms of postcolonial oppression and their implications for the ethnographic encounter

    Psychosocial Consequences of Caregiver Transitions for Maltreated Youth Entering Foster Care: The Moderating Impact of Community Violence Exposure

    Get PDF
    Youth who experience a greater number of caregiver transitions during childhood are at risk for developing a host of psychosocial problems. Although researchers have examined individual-level factors that may moderate this association, no known studies have examined the impact of community-level factors. The current study investigated whether community violence exposure (CVE) moderated the association between number of prior caregiver transitions and increases in levels of externalizing and internalizing problems for a sample of youth entering foster care. Participants included 156 youth (aged 9-11 at first assessment) removed from their homes because of maltreatment. Youth provided reports of caregiver transitions and CVE at baseline, and caregivers, teachers, and youth reported on externalizing and internalizing problems 18-22 months later. Results from hierarchical multiple regression analyses indicated that youth with a greater number of caregiver transitions and higher levels of CVE evidenced significant increases in levels of psychosocial problems. The results of the study are discussed in terms of their implications for child welfare services
