This study explores how a scientist's location in science‐based policy networks can affect her policy‐oriented behaviors. In particular, we hypothesize that those scientists who fill structural holes in their networks will be more likely than others to engage in policy‐oriented behaviors. The network data are defined by scientists' coauthorship on policy documents regarding climate change in the Great Lakes. We employ a two‐mode network analysis to identify clusters of scientists who coauthored similar documents, and relative to those clusters, we identify those who fill structural holes by bridging between clusters. We find that those scientists who bridged between clusters were more likely to engage in policy‐oriented behaviors of policy advocacy and advising than were others in the network. This is an example of a link between network location and policy‐oriented behavior indicative of the broader phenomenon of how individuals exert agency, given structural constraints. 相似文献

The initial Late Paleolithic, said to appear between 40 and 30 kya in eastern Asia, is defined by the appearance of many innovations. These archaeological indicators include the appearance of more refined stone tool making techniques (e.g., include the appearance of blade and microblade technology), complex hearth construction, use of pigments and personal ornamentation, as well as worked faunal implements such as bone and antler tools. We report here new findings from a multidisciplinary research project conducted at the Shuidonggou (Choei-tong-keou) site complex in northern China, a series of localities that date from the initial Late Paleolithic to the Neolithic. 相似文献

This article offers a canine history of the “critical period” concept, situating its emergence within a growing, interdisciplinary network of canine behavior studies that connected eugenically minded American veterinarians, behavioral geneticists, and dog lovers with large institutional benefactors. These studies established both logistical and conceptual foundations for large-scale science with dogs while establishing a lingering interdependence between American dog science and eugenics. The article emphasizes the importance of dogs as subjects of ethological study, particularly in the United States, where some of the earliest organized efforts to analyze canine behavior began. Further, the article argues that the “critical period” is important not only for its lasting prominence in multiple fields of scientific inquiry, but also as a historiographical tool, one that invites reflection on the tendency of historians to emphasize a particular narrative structure of scientific advancement. 相似文献

This paper is dedicated to one of the outstanding scientists of the twentieth century—Ivane Beritashvili. He was a Georgian physiologist who graduated from St. Petersburg University and worked under the supervision of N. Wedensky. He founded the Department of Physiology and the Institute of Physiology at the University of Tbilisi, Georgia. Among his numerous contributions was the discovery of the rhythmical course of reciprocal inhibition in spinal reflexes, the first demonstration of the excitatory and inhibitory reactions in the brain stem neuropil. But Beritashvili's most significant contribution was the discovery of the mediation of animal psychoneural behavior by image-driven memory. 相似文献

At a time when Japanese foreign policy was constrained by the legacies of war and the exigencies of the Cold War, hosting the 1964 Tokyo Olympics was conceived as an alternative means of engagement with the international community. The sporting diplomacy of the Tokyo Olympics centered around elevating Japan’s international position by engaging the people of the world on a grassroots level. The pervasive notion that sports are separate from politics helped smooth Japan’s return to the international community, while concerns about the image presented to foreign audiences motivated efforts to internationalize Japan, in terms of both the physical infrastructure of the capital and attitudes of the people. The development of infrastructure for the Games—including new buildings, roads, and trains, and even a satellite to facilitate live international broadcast—all contributed to making Japan more “international.” The event was a great success for Japan, both athletically and diplomatically, and sports diplomacy became a lasting component of Japan’s foreign policy, still used today to promote international connections and develop greater knowledge and understanding of Japan. At the same time, this build-up of soft power also cleared the way for the development of greater hard power by Japan. 相似文献

北京王府井大街消费行为的空间特征分析 总被引:4,自引:1,他引:3
根据对北京市王府井大街消费者调查所获数据的分析,以地块为分析单位从空间角度探讨消费者的行为特征,包括人流、停留人次、消费金额、人均消费金额等要素的空间分布的基本特征以及入口、回游、出口各阶段的空间特征,以认识消费行为的复杂性和影响因素的多样性。
研究发现:总消费额与消费者人数的相关性远高于人均消费,显示了商业街经济活动以量取胜的现实;是否位于步行街区域及是否设有大型百货公司的影响在每个层面都得到了很明显的体现;另外由于公共交通所决定的出入口区也影响到了附近地块的商业表现。对出入口位置以及起始、回游、结束三地块消费者的人流分布的分析表明:位于起始消费阶段的消费者的人均消费额要远高于其他阶段。消费者的回游流动特点:①具有沿步行街区域由南向北的明显方向性;②相邻地块回游较为频繁;③步行街内部回游频繁,以外地区,特别是离主要出入口较远的北部区域鲜有人的活动;④大型百货之间的回游,特别是对面地块之间的互串较为频繁,最大的回游出现在新东安市场-北京市百货大楼。 相似文献

我国出境旅游者不文明行为改变的策略研究 总被引:1,自引:0,他引:1
我国公民在出境旅游中的不文明行为现状与日益强调国家软实力的国际竞争趋势,使提升国民文明素质变得更为紧迫。然而,国民文明素质的提升是一项持久工程,国家软实力的较量却在时刻进行。我国快速发展的出境旅游既向国民提出了提升文明素质的要求,也面临着急需即时改变旅游不文明行为的压力。本文首先对以往改变旅游不文明行为的误区进行了剖析,然后在分析旅游者不文明行为发生与改变规律的基础上,对旅游不文明行为改变的阶段性特征进行了讨论,进而针对改变不文明行为的关键点提出了积极的对策。 相似文献
