When Epistemic Communities Fail: Exploring the Mechanism of Policy Influence

Epistemic communities are an established concept in the study of international relations but can also explain policy change at the domestic level. This article asks why some epistemic communities manage to convince decision makers of their preferred policies while others do not. It suggests that the reason lies in the causal mechanism of epistemic communities' influence on decision makers, mediated by decision makers' demand for expert input. Most epistemic communities scholarship focuses on single case studies where the communities' influence on policy was strong and clear, leading to an overestimation of the groups' influence. To help correct this probable bias, this article compares a successful case of epistemic community influence (health technology assessment in Poland) with an unsuccessful example of the same policy (in the Czech Republic). The juxtaposition allows for unpacking of the necessary parts of the causal mechanism (emergence of an epistemic community, its activity, access to decision makers, and successful suasion) and separating them from the crucial scope condition. Decision makers' uncertainty about the policy issue at hand has traditionally been the key scope condition for epistemic communities but the successful Polish case demonstrates that epistemic communities can be influential even in highly certain areas of routine policymaking, leading to a reconceptualization of uncertainty as policymakers' demand for expert input. Demand can originate from various sources, but any change of it affects individual parts of the causal mechanism, leading to a success or failure of epistemic communities' policy enterprise.     

巴马盘阳河流域季节性移民社区类型与形成机理

季节性移民聚居现象受到西方学术界的极大关注,而我国鲜有研究。采用观察法和访谈法,对巴马盘阳河流域"一地多类"的季节性移民社区的形成过程、类型特征与作用机理进行归纳与揭示。研究表明：①季节性移民社区演变历经萌芽、快速参与和转型发展三个阶段,社区人口结构、聚居空间、经济业态、景观设施及人文氛围在不同时期呈现出不同的特征;②季节性移民社区形态存在差异,可以归类为交融性社区、优势性社区,共享性社区,纯粹性社区。③季节性移民社区是差异化的"美好生活"需求、独特的长寿资源及乡村生活环境、外来商业资本、地方政府调控和利益共生等"五力驱动"的结果,不同发展阶段其主导动力和作用方式存在差异。     

明代年例银制度形成探论

明代年例银制度是经过长期演变逐渐形成的一项军事供给制度。宣德十年(1435)首先出现京运银,历经景泰、天顺时期,京运银两中有一笔银两开始向"岁例"发生制度性转变的趋势;成化、弘治之际,"常数"、"岁运"、"岁例"、"年例"、"年例银"等名称的出现是这笔京运银两制度化发展的结果,标志着明代年例银制度的初步形成;嘉靖十六年(1537)年例银一年一发的规定以及年例银会计预算制的出现,意味着明代年例银制度的完全确立。年例银制度的形成和确立,改变了明代国家的军事供给体制,是明代军事财政史上的一个重大变革。     

我国古典诗歌传统对新诗的影响

从"五四"运动到今天,新诗已经走过了80多年的历程。这一历史进程曲折复杂而又历尽艰辛,从文化传统和美学的角度看,新诗与古典诗歌不但没有不可逾越的鸿沟,而且有着谁也不能割断的民族的血缘。我国古典诗歌传统对新诗有着深远的影响。     

洪业对顾颉刚的学术影响

洪业对崔述《知非集》、《荍田剩笔》等著作进行研究,系统梳理了崔述著作的版本流传、学术思想和生平事迹,这对顾颉刚整理和编订《崔东壁遗书》是有价值的。洪业主持的哈佛燕京学社引得编纂处支持了顾颉刚的《尚书》研究。在《禹贡》半月刊、禹贡学会的创立和以通俗读物的形式宣传抗日的工作中,洪业作出了自己的贡献,这些都对顾颉刚的学术产生了有意义的影响。     

生命哲学视野下旅游研究与实践方向的探索

近年来,旅游业已然成为中国国民经济的战略性支柱产业,但以经济发展为主要目标的旅游研究却呈现出固化和乏味的态势。未来旅游研究应科学与哲学齐头并进,与生命哲学的结合,更是旅游研究顺应时代发展的应有之义。文章以生命哲学研究的主要内容梳理为切入点,探索旅游生命观的形成,以生命哲学视野下的旅游概念与本质为整个研究体系的逻辑起点,分析生命哲学视域下旅游发展的内在机理,从矛盾论、价值论的视角逐步探讨未来旅游的研究与实践方向。结合当今时代特征,发现生命哲学下的旅游本质应是体察风景、体验生活与体悟生命的统合。人与自然共同构建生命共同体,科学旅游发展观应转向“以生命为本”,未来旅游的最终目的是促进人的生命自由和全面发展,实现人与自然的生命延续。     

论中国古代治边思想的特点、演变和影响

古代治边思想大体形成于秦汉,发展和延续至清代,其内涵是动态变化的,经历了从肤浅到成熟的过程,各个时期的治边思想又有其特色。古代治达思想总体上有两个基本的特点：统治对开疆拓土多持相对保守的态度,认为理想的边疆治理是“守在四夷”;从“华夷有别”的治边观出发,在边疆地区施行相对宽松的羁縻统治,同时重视在边疆传播封建化的教化作用。章还以封建统治对边疆民族的治策和对边疆的经济开发为例,阐述了古代治达思想对边疆治策的广泛影响。     

INTELLECTUAL HISTORY CONFRONTS THE LONGUE DURÉE

This review of John Potts's Ideas in Time: The Longue Durée in Intellectual History discusses the advantages and disadvantages of writing intellectual histories that embrace the longue durée. It applauds Potts's concise account of historiographical discussions of continuity and discontinuity in the history of ideas in the last seventy-five years but laments his failure to discuss the contributions of historians of science and scholarship to the practices of knowledge-making and to the transmission of ideas. It suggests that the study of discontinuities can also be rich and revealing, and it proposes one approach to understanding the ways in which ideas go out of fashion. It concludes by noting, first, that the models that contemporary historians of ideas adopt also have to do with book-market opportunities and pressures and, second, that we have work to do to engage our contemporaries and students in whatever form of intellectual history we choose to write.     

Evaluating Stakeholder Participation and Influence on State-Level Rulemaking

Despite sustained attention to the role of stakeholders in policymaking—both in legislative and regulatory venues—we lack a systematic understanding of whether and when stakeholders wield influence over decisions. This is particularly true regarding state-level rulemaking in the United States, which has become an important venue of policy action as federal policymaking is increasingly stymied. Although the specifics of the rulemaking process vary to some degree across states, determining whether common patterns of stakeholder influence exist across states and issue areas can advance our understanding of regulatory institutions more broadly. This study contributes to the growing body of scholarship on state-level rulemaking by analyzing the ways in which stakeholders participate in rulemaking processes and the effects on rulemaking decisions of such participation in three policy domains across five states. We find that while industry may be influential during rulemaking across cases, consequential opportunities for non-industry stakeholders to influence regulatory decisions also exist.     

山西省转型期旅游场强时空异质性特征及机制

以山西省转型期旅游发展为例,选取2005、2011和2017年17项指标构建城市旅游发展综合实力评价体系,基于改进场强模型,借助GIS技术和地理探测器模型,分析旅游场强时空异质性特征及演变机制。结果表明：①旅游场强高值区范围扩大、逐步形成叶脉状网络空间形态,突破了早期“人”形格局限制;②各地市旅游场强前期整体上升,后期集中在大西高铁沿线,城市绝对差异增加,高级别场强类型主要以太原市为中心向边缘扩散演替;③旅游场强空间格局演变具有时序性特征,主导因子经历了二元、三元主导和多元共同作用阶段,对于旅游产业后发省份构建区域旅游场强空间格局具有借鉴和指导意义。
