This article discusses the ethics of knowledge production (KP) from a cultural point of view, in contrast with the more usual emphasis on the ethical issues facing individuals involved in KP. Here, the emphasis is on the cultural environment within which individuals, groups and institutions perform KP. A principal purpose is to suggest ways in which reliable scientific knowledge could be produced more efficiently. The distinction between ethical hazard and (un)ethical behaviour is noted. Ethical hazards cannot be eliminated but they can be reduced if the cultural ambience is suitable. The main suggestions for reducing ethical hazards in KP relate to the review process. It is argued that some defects of the current, largely anonymous, review process could be ameliorated by a process of comprehensive, open and ongoing review (COOR). This includes partial professionalisation of the work of reviewing. Review at several stages is a vital part of the long filtering that incorporates some claims into the canon of reliable knowledge. The review process would be an acknowledged and explicit part of KP—a respected, public and rewarded activity. COOR would be expensive but cost-effective. The costs should be built explicitly into research culture. Finally, the considerations about a more ‘KP friendly’ culture lead to advocacy of a ‘long-term, short-term’ synthesis; that is, of the synthesis of long-term vision, such as a more cooperative and less competitive culture, with incremental changes which may be implemented in the short term. 相似文献

Some subjectivist views of practical reasons entail that some people, in some cases, lack sufficient reasons to act as morality requires of them. This is often thought to form the basis of an objection to these subjectivist views: ‘the amoralism objection’. This objection has been developed at length by Julia Markovits in her recent book Moral Reason. But Markovits—alongside many other proponents of this objection—does not explicitly consider that her objection is premised on a claim that her opponents deny on first-order grounds, often as part of a socially and politically motivated revisionism about the assessment of agents and their actions. As such, the amoralism objection as she presents it misses its dialectical mark. This has interesting consequences for subjectivism—and the methodology behind it—more generally. 相似文献

We study how job-related well-being (measured by Warr’s ‘Enthusiasm’ and ‘Contentment’ scales) altered through the Great Recession, and how this is related to changing job quality. Using nationally representative data for Britain, we find that job-related well-being was stable between 2001 and 2006, but then declined between 2006 and 2012. We report relevant changes in job quality. In modelling the determinants of job-related well-being, we confirm several previously-studied hypotheses and present some new findings: downsizing, work re-organisation, decreased choice, and linking pay to organisational performance each reduce well-being; indicators of skills challenge in jobs have more of a positive association with Enthusiasm than with Contentment, while effort has a more negative association with Contentment than with Enthusiasm. Our estimates are largely orthogonal to the effects of personality traits and demographic controls on well-being. Using a standard decomposition, we find that the 2006–2012 fall in job-related well-being is partly accounted for by accelerations in the pace of workplace change, rising job insecurity, increased effort and changing participation. 相似文献

Encoding multiple cues can improve the accuracy and reliability of navigation and goal localization. Problems may arise, however, if one cue is displaced and provides information which conflicts with other cues. Here we investigated how pigeons cope with cue conflict by training them to locate a goal relative to two landmarks and then varying the amount of conflict between the landmarks. When the amount of conflict was small, pigeons tended to integrate both cues in their search patterns. When the amount of conflict was large, however, pigeons used information from both cues independently. This context-dependent strategy for resolving spatial cue conflict agrees with Bayes optimal calculations for using information from multiple sources. 相似文献

The learning landscape of the higher education environment is changing, with an increased focus over the past decade on how educators might begin to cultivate reflective skills in health professions students. In addition, changing professional requirements demand that health professionals are adequately prepared to practise in today’s complex healthcare systems, including responding to changing demographics of population ageing. In this educational case study, we will share how we (a group of education, medical and nursing academics) developed ‘Depth of Field: Exploring Ageing’ a digital, consumer-driven, interprofessional reflective learning resource that uses photographs, narrative and small-group work to strengthen reflective capacity in current and/or future health professionals. 相似文献

This paper examines the acculturation process of male Central American-origin youths in Toronto, a group who are known to have a higher than average risk of dropping out of high school. Using data from semi-structured interviews with a small sample of male youths born in the region or born in Canada to parents from the region, we examine interrelated and shifting friendship patterns, ethno-social identities, and aspirations for schooling. The findings reveal that some youths become marginalized with weak friendship networks, diffuse ethno-social identities and low school completion aspirations, while others develop relatively strong affiliations exclusively with co-ethnic friends who have modest school completion goals. The strongest trend was toward being integrated with a mix of co-ethnic friends and those from other backgrounds, hybrid ethno-social identities, and higher schooling goals. The analysis examines whether the youths are aware of the relationships between social belonging and academic belonging, and whether they feel it possible to escape from being “boxed in” to acculturation patterns associated with poor school completion. These findings add to research on efforts to understand and improve schooling outcomes for “at risk” minority youth in a multicultural city. 相似文献
