In this article, we raise ethical concerns about the potential misuse of open-source biology (OSB): biological research and development that progresses through an organisational model of radical openness, deskilling, and innovation. We compare this organisational structure to that of the open-source software model, and detail salient ethical implications of this model. We demonstrate that OSB, in virtue of its commitment to openness, may be resistant to governance attempts. 相似文献

This study investigated the shared and distinct associations between depressive and anxious symptoms and motives for pursuing personal goals. One hundred and thirty-six undergraduates generated approach and avoidance goals and rated each on intrinsic, identified, introjected and external motives. Anxious and depressive symptoms showed significant unique associations with distinct motives. Specifically, depressive symptoms predicted significant unique variance in intrinsic motivation for approach goals (but not avoidance goals), whereas anxious symptoms predicted significant unique variance in introjected regulation for approach and avoidance goals. Some of these findings were moderated by gender. The findings broadly support the notion that depression is uniquely characterised by reduced enjoyment of approach goal pursuit whereas anxiety is uniquely characterised by pursuit of goals in order to avoid negative outcomes. We suggest that these findings are compatible with regulatory focus theory and suggest that motives for goal pursuit are important in understanding the relation between goals and specific mood disorder symptoms. 相似文献

Recent insights show that increased motivation can benefit executive control, but this effect has not been explored in relation to semantic cognition. Patients with deficits of controlled semantic retrieval in the context of semantic aphasia (SA) after stroke may benefit from this approach since ‘semantic control’ is considered an executive process. Deficits in this domain are partially distinct from the domain-general deficits of cognitive control. We assessed the effect of both extrinsic and intrinsic motivation in healthy controls and SA patients. Experiment 1 manipulated extrinsic reward using high or low levels of points for correct responses during a semantic association task. Experiment 2 manipulated the intrinsic value of items using self-reference, allocating pictures of items to the participant (‘self’) or researcher (‘other’) in a shopping game before participants retrieved their semantic associations. These experiments revealed that patients, but not controls, showed better performance when given an extrinsic reward, consistent with the view that increased external motivation may help ameliorate patients’ semantic control deficits. However, while self-reference was associated with better episodic memory, there was no effect on semantic retrieval. We conclude that semantic control deficits can be reduced when extrinsic rewards are anticipated; this enhanced motivational state is expected to support proactive control, for example, through the maintenance of task representations. It may be possible to harness this modulatory impact of reward to combat the control demands of semantic tasks in SA patients. 相似文献

Empirical studies of sexual offender recidivism have proliferated in recent decades. Virtually all of the studies define recidivism as a new legal charge or conviction for a sexual crime, and these studies tend to find recidivism rates of the order of 5–15% after 5 years and 10–25% after 10+ years. It is uncontroversial that such a definition of recidivism underestimates the true rate of sexual recidivism because most sexual crime is not reported to legal authorities, a principle known as the “dark figure of crime.” To estimate the magnitude of the dark figure of sexual recidivism, this paper uses a probabilistic simulation approach in conjunction with the following: (i) victim self‐report survey data about the rate of reporting sexual crime to legal authorities; (ii) offender self‐report data about the number of victims per offender; and (iii) different assumptions about the chances of being convicted of a new sexual offense given that it is reported. Under any configuration of assumptions, the dark figure is substantial, and as a consequence the disparity between recidivism defined as a new legal charge or conviction for a sex crime and recidivism defined as actually committing a new sexual crime is large. These findings call into question the utility of recidivism studies that rely exclusively on official crime statistics to define sexual recidivism, and highlight the need for additional, long‐term studies that use a variety of different measures to assess whether or not sexual recidivism has occurred. 相似文献

The conjecture that negative emotions underpin support for far‐right politics is common among pundits and scholars. The conventional account holds that authoritarian populists catalyze public anxiety about the changing social order and/or deteriorating national economic conditions, and this anxiety subsequently drives up support for the far right. We propose that while emotions do indeed play an independent causal role in support for far‐right parties and policies, that support is more likely built upon the public’s anger rather than fear. This article explores the relative impact of fear and anger in reaction to the 2015 Paris terror attacks on the propensity to vote for the French far‐right party, the Front National, in the 2015 regional elections. Contrary to conventional wisdom, we find that anger is associated with voting for the Front National, while fear is associated with voting against the Front National. Moreover, anger boosts the Front National vote most powerfully among far‐right and authoritarian voters. On the other hand, fear reduces support for the far right among those same groups. 相似文献
