The dual-use issue is often framed as a series of paralyzing ‘dilemmas’ facing the scientific community as well as institutions which support innovation. While this conceptualization of the dual-use issue can be useful in certain contexts (such as in awareness-raising and as part of educational activities directed at the scientific community) its usefulness is more limited when reflecting on the governance and politics of the dual-use issue. Within this paper, key shortcomings of the dilemma framing are outlined. It is argued that many of the issues raised in the most recent debates about ‘dual-use’ bird flu research remain unresolved. This includes questions about the trajectories of certain lines of research, as well as broader trends in the practice and governance of science. This leads to difficult questions about current approaches to the dual-use issue within the US, as well as internationally. 相似文献

Emerging findings from studies with infants at familial high risk for autism spectrum disorder (ASD), owing to an older sibling with a diagnosis, suggest that those who go on to develop ASD show early impairments in the processing of stimuli with both social and non‐social content. Although ASD is defined by social‐communication impairments and restricted and repetitive behaviours, the majority of cognitive theories of ASD posit a single underlying factor, which over development has secondary effects across domains. This is the first high‐risk study to statistically differentiate theoretical models of the development of ASD in high‐risk siblings using multiple risk factors. We examined the prediction of ASD outcome by attention to social and non‐social stimuli: gaze following and attentional disengagement assessed at 13 months in low‐risk controls and high‐risk ASD infants (who were subsequently diagnosed with ASD at 3 years). When included in the same regression model, these 13‐month measures independently predicted ASD outcome at 3 years of age. The data were best described by an additive model, suggesting that non‐social attention, disengagement, and social attention as evidenced by gaze following, have a cumulative impact on ASD risk. These data argue against cognitive theories of ASD which propose that a single underlying factor has cascading effects across early development leading to an ASD outcome, and support multiple impairment models of ASD that are more consistent with recent genetic and neurobiological evidence. 相似文献

Recently, Walter Sinott-Armstrong and Justin Snedegar have argued for a general contrastivist theory of reasons. According to the contrastivist account of reasons, all reasons claims should be understood as a relation with an additional place for a contrast class. For example, rather than X being a reason for A to P simpliciter, the contrastivist claims that X is a reason for A to P out of {P,Q,R…}. The main goal of this paper is to argue that the contrastivist account of reasons will be ill-fitted for accommodating certain features of moral reasons. In brief, the reason why the contrastivist analysis fails is that it cannot adequately allow for cases of morally correct whole-hearted action—cases where consideration of any alternate course of action would be misguided. But, if all consideration of alternate courses of action is misguided, then it is hard to see how one can set the relevant contrast class that is essential to the contrastivist view—any contrast class will seem out of place. In addition, I address some of the arguments that have been given in favor of the contrastivist account of reasons and argue that there are at least two ways that the non-contrastivist can respond to these arguments. 相似文献
