Abstract

Scalability can be understood as the ability to expand without changing. Yet, expanding an intervention to a global scale, we suggest, is a significant and difficult accomplishment. In this paper we propose to explore the kind of evidential exigencies that this accomplishment involves. To do so, we focus on the field of global health and examine how child immunization against the pneumococcus bacterium has been scaled up in low-income countries. The paper first attends to initial epidemiological scrutiny that revealed the existence of a large-scale public health problem and the possibility of an expandable solution (vaccination). It then describes the set-up of a funding arrangement using overseas aid to purchase vaccine doses manufactured by pharmaceutical companies, before paying attention to various frictions that affect the widespread use of pneumococcal vaccines. In these different moments through which scalability is accomplished, always partially and temporarily, we show that a dual activity can be witnessed, a pivoting between referential work and forward projection. To conclude, we suggest that scalability is more usefully approached as a form of expansion that is always attentive to the possibilities of change.  相似文献

Insects and ‘the swarm’ as metaphors and objects of research have inspired works in the genres of science fiction and horror; social and political theorists; and the development of war-fighting technologies such as ‘drone swarms’, which function as robot/insect hybrids. Contemporary developments suggest that the future of warfare will not be ‘robots’ as technological, individualised substitutions for idealised (masculine) warfighters, but warfighters understood as swarms: insect metaphors for non-centrally organised problem-solvers that will become technologies of racialisation. As such, contemporary feminist analysis requires an analysis of the politics of life and death in the insect and the swarm, which, following Braidotti (2002), cannot be assumed to be a mere metaphor or representation of political life, but an animating materialist logic. The swarm is not only a metaphor but also a central mode of biopolitical and necropolitical war, with the ‘terrorist’ enemy represented as swarm-like as well. In analysing the relations of assemblage and antagonism in the war ontologies of the drone swarm, I seek inspiration from what Hayles (1999, p. 47) describes as a double vision that ‘looks simultaneously at the power of simulation and at the materialities that produce it’. I discuss various representations and manifestations of swarms and insect life in science/speculative fiction, from various presentations of the ‘Borg’ in Star Trek (1987–1994, 1995–2001, 1996), Alien (1979) and The Fly (1958, 1986) to more positive representations of the ‘becoming-insect’ as possible feminist utopia in Gilman’s Herland (2015 [1915]) and Tiptree’s Houston, Houston, Do You Read? (1989 [1976]). Posthuman warfare also contains the possibilities of both appropriating and rewriting antagonisms of masculine and feminine in the embodiment of the subject of war in the swarm. This piece seeks to analyse new ways of feminist theorising of the relations of power and violence in the embodiment of war as the swarm.  相似文献

African indigenous vegetables (AIVs) have potential to sustainably address malnutrition, a growing problem in sub-Saharan Africa. Their consumption is however, limited by poor perceptions and lack of awareness of nutritional benefits. There is limited evidence of the effectiveness of community-focused information dissemination approaches in influencing participants’ perceptions and uptake of innovations in AIVs to address malnutrition. This article aims to fill this knowledge gap, using a case study focusing on pastoral communities in Monduli district in northern Tanzania. Target communities participated in a community-based nutritional outreach facilitated by the Good Seed Initiative (GSI), held at Monduli district hospital in September 2014. The results provide evidence of the achievements of the GSI intervention, and the effectiveness of alternative information dissemination approaches.  相似文献
