Falk Daviter 《Policy Studies》2017,38(6):571-588
One of the truisms of policy analysis is that policy problems are rarely solved. As an ever-increasing number of policy issues are identified as an inherently ill-structured and intractable type of wicked problem, the question of what policy analysis sets out to accomplish has emerged as more central than ever. If solving wicked problems is beyond reach, research on wicked problems needs to provide a clearer understanding of the alternatives. The article identifies and explicates three distinguishable strategies of problem governance: coping, taming and solving. It shows that their intellectual premises and practical implications clearly contrast in core respects. The article argues that none of the identified strategies of problem governance is invariably more suitable for dealing with wicked problems. Rather than advocate for some universally applicable approach to the governance of wicked problems, the article asks under what conditions different ways of governing wicked problems are analytically reasonable and normatively justified. It concludes that a more systematic assessment of alternative approaches of problem governance requires a reorientation of the debate away from the conception of wicked problems as a singular type toward the more focused analysis of different dimensions of problem wickedness. 相似文献

The role of normative reflection and the possibilities of ethical inquiry in technology assessment have been under discussion in the TA community for several years. As an outcome of this discussion the necessity of explicitly dealing with normativity in TA has widely been acknowledged. However, it is still quite unclear in which way this should be done. This paper is dedicated to the role (and limitations) of ethical expertise in this field, especially in HTA. By methodological analysis an approach is developed to show how entry points for ethical expertise could be identified. The result is that ethical expertise can inform moral debates by uncovering underlying assumptions, by making the normative structure of argumentation transparent, and by weighing the strength of the arguments. In this way moral debates in HTA can become more transparent and opened to argumentative reasoning instead of consisting of bargaining processes determined by power distributions. Ethical reflection, however, does not replace decision-making. 相似文献

With more and better clinical data being captured outside of clinical studies and greater data sharing of clinical studies, external controls may become a more attractive alternative to randomized clinical trials (RCTs). Both industry and regulators recognize that in situations where a randomized study cannot be performed, external controls can provide the needed contextualization to allow a better interpretation of studies without a randomized control. It is also agreed that external controls will not fully replace RCTs as the gold standard for formal proof of efficacy in drug development and the yardstick of clinical research. However, it remains unclear in which situations conclusions about efficacy and a positive benefit/risk can reliably be based on the use of an external control. This paper will provide an overview on types of external control, their applications and the different sources of bias their use may incur, and discuss potential mitigation steps. It will also give recommendations on how the use of external controls can be justified. 相似文献

For a few years now German universities have the opportunity to employ teaching professors and lecturers with fixed-term work contracts. Trutz von Trotha, Armin Nassehi and Jo Reichertz discuss the implications that this development may have for university employment structures as well as for the future of research and teachings. 相似文献

Abstract Rural sociology has been closely tied to the research and policy agendas of America's land grant colleges and universities. Because of this, the contributions of rural sociologists have been more applied and focused than those of the discipline as a whole. The Rural Sociological Society serves as an important venue that unifies the discipline. Phenomenologically speaking, we are who we are because of where we are. 相似文献

This paper studies risk attitudes using a large representative survey and a complementary experiment conducted with a representative subject pool in subjects' homes. Using a question asking people about their willingness to take risks “in general”, we find that gender, age, height, and parental background have an economically significant impact on willingness to take risks. The experiment confirms the behavioral validity of this measure, using paid lottery choices. Turning to other questions about risk attitudes in specific contexts, we find similar results on the determinants of risk attitudes, and also shed light on the deeper question of stability of risk attitudes across contexts. We conduct a horse race of the ability of different measures to explain risky behaviors such as holdings stocks, occupational choice, and smoking. The question about risk taking in general generates the best all‐round predictor of risky behavior. 相似文献

Ephemeral social media, platforms that display shared content for a limited period of time, have become a prominent component of the social ecosystem. We draw on experience sampling data collected over two weeks (Study 1; N?=?154) and in-depth interview data from a subsample of participants (Study 2; N?=?28) to understand college students’ social and emotional experiences on Snapchat, a popular ephemeral mobile platform. Our quantitative data demonstrated that Snapchat interactions were perceived as more enjoyable – and associated with more positive mood – than other communication technologies. However, Snapchat interactions were also associated with lower social support than other channels. Our qualitative data highlighted aspects of Snapchat use that may facilitate positive affect (but not social support), including sharing mundane experiences with close ties and reduced self-presentational concerns. In addition, users compared Snapchat to face-to-face interaction and reported attending to Snapchat content more closely than archived content, which may contribute to increased emotional rewards. Overall, participants did not see the application as a platform for sharing or viewing photos; rather, Snapchat was viewed as a lightweight channel for sharing spontaneous experiences with trusted ties. Together, these studies contribute to our evolving understanding of ephemeral social media and their role in social relationships. 相似文献

We provide evidence that long‐term relationships between trading parties emerge endogenously in the absence of third party enforcement of contracts and are associated with a fundamental change in the nature of market interactions. Without third party enforcement, the vast majority of trades are initiated with private offers and the parties share the gains from trade equally. Low effort or bad quality is penalized by the termination of the relationship, wielding a powerful effect on contract enforcement. Successful long‐term relations exhibit generous rent sharing and high effort (quality) from the very beginning of the relationship. In the absence of third‐party enforcement, markets resemble a collection of bilateral trading islands rather than a competitive market. If contracts are third party enforceable, rent sharing and long‐term relations are absent and the vast majority of trades are initiated with public offers. Most trades take place in one‐shot transactions and the contracting parties are indifferent with regard to the identity of their trading partner. 相似文献
