现阶段,我国步入了创新驱动引领升级的关键时期,科技创新受到了整个社会的空前重视。科技保险作为分散和转移科技风险的重要手段,可以为科技创新提供有力的风险保障。目前,我国科技保险工作已经进入全面推广阶段,虽然取得了一定的成效,但整体运行并不理想,科技企业参保率低,科技保险缺失严重。究其原因,主要在于制度供给不能适应科技企业对科技保险的需求,科技保险制度供求非均衡,在现行的科技保险制度下积聚着大量的潜在利润,而这些潜在利润既是科技保险制度非均衡的原因,又是科技保险制度创新的动力。  相似文献

I call for a globally informed sociology of comparative placemaking that integrates historical and contemporary processes and includes the ephemeral, institutional, and personal. By placemaking, I am referring to the explicit or tacit cooperation among people to create, maintain, and give meaning to places in space through bodily occupation given differential resources and constraints. I review select place, space, and community-based literature about urban, Black, migrant, LGBTQ, and international populations to think about how we can build upon and integrate multiple theoretical, methodological, and epistemological insights to form an explicit placemaking research agenda. A US focus on neighborhoods contrasts with a comparative examination of global urban networks, social polarization, and transformation of the built environment in the interdisciplinary field of global urban studies (Ren, 2018). I argue for a placemaking research agenda that bridges insight from US Urban Sociology with Global Urban Studies to consider how various structures and actors constrain and facilitate place projects. With a globally reaching and comparatively informed sociology of placemaking, we can illuminate our multi-structured story of place and agency in context. We can answer questions about how and why we co-create and are simultaneously disciplined by the process of creation.  相似文献

丹巴位于“藏彝走廊”的核心区域,其对汉藏民族关系、中央政权与边疆地区的稳定均具有重要影响。自忽必烈时期开始丹巴即开始实行土司制度直至新中国成立,研究丹巴的土司制度发展历史对梳理“藏彝走廊”民族关系及社会发展历史具有重要作用。本文对丹巴土司制度的发展历史进行了考证,并对其境内的四个土司的管辖范围、权力地位进行了梳理,以期对该地区历史发展研究提供一些参考与借鉴。  相似文献

《左传·郑伯克段于鄢》是非常著名的历史叙述文本,讲述了庄公兄弟二人为王位而反目成仇的过程。《左传》评价"兄不友、弟不恭"的伦常失序是事件的起因。后世评论多以此为据,而忽视兄弟二人的母亲武姜的政治力量。清华简第六辑《郑武夫人规孺子》,塑造出颇具政治谋略的武姜,综合《左传·郑伯克段于鄢》的叙述,借助历史重演解释理论分析可知,她与庄公多年秘而不宣的政治角力,是郑伯克段叙述中的内隐的政治背景。庄公借助边父、祭仲等人的长久筹谋,因势利导,驱逐共叔段、拘禁武姜,避免郑国内乱,为国家兴盛谋求发展空间,但他养骄长恶,一贯以满足个体私欲来豢养王室及其近属,为郑国埋下内乱的祸根。  相似文献

Published articles may be retracted when their findings are no longer considered reliable due to honest error, publication misconduct, or research misconduct. This article focuses on the case of a single serial violator of research and publication ethics in anesthesiology and critical care, which is widely publicized. A chain of events led to detection of misconduct that had substantial impact on the evidence base for the safety of hydroxyethyl starch, an intravenous artificial colloid solution, which is reflected in current guidelines on fluid management and volume resuscitation. As citations to retracted works continue to be a cause for concern, this article reviews the retraction status of this author’s published articles to determine whether sufficient action has been taken to retract his body of work. Results show that retraction practices are not uniform and that guidelines for retraction are still not being fully implemented, resulting in retractions of insufficient quantity and quality. As retractions continue to emerge for the author’s publications, with ten more since 2011, and as they are generally increasing, these data on retractions not only provide findings of misconduct, but also allow us to make inferences about ongoing weaknesses in the system of scientific literature.  相似文献

Computer simulations are increasingly used within various fields of the social sciences, including analytical sociology and computational social science. However, the method has yet to fully find its place within critical realism, generally regarded as reductionist and methodological individualist and thus inadequate to the task of grasping the full and enigmatic complexity of social life. This article contributes to the discussion by suggesting an alternative approach to computer simulations in the social realm. Instead of representing reality, simulations are seen as a way of boosting abstraction by enabling us to isolate and study the effects of emergent mechanisms. The need for such tools is growing more urgent in an age characterized by rapid change and global networks of causal interrelation. Hence there is a need not only for new tools to deal with causal complexity within critical realism, but also for a critical realist perspective to fill the meta‐theoretical vacuum on which the simulation approach is largely based. The approach developed here provides a challenge to the predominant ways in which simulations are utilized today, with increasingly sophisticated models aiming towards realistic representation on the basis of empirical data.  相似文献

The commander was mainlu in charge of the army in the local administration system during the Han Dynasty to the Sunwu Period. As the border prefectures were important in military defense, the armies of these prefectures were commonly divided into parts. Therefore, the army of Kuaiji Prefecture were divided into West Section Duwei, East Section Duwei and South Section Duwei. The West and East Section Duweis were founded for the purpose of suppressing the adherents of Yuyue as well as the Minyue and Ouyue people in the southeast coastline. In demand of securing the safety of the ship routes alongside the southeast coastline, the East Section Duwei migrated frequently within the area. In the meantime, the foundation of South Section Duwei was the result of the Sunwu government suppressing the local force and pillaging the labor resources in a partition background  相似文献
