基于手机信令数据的大型足球赛事球迷当日空间行为特征研究

利用手机信令数据,以2014年3月上海申花与杭州绿城、上海上港对上海申鑫两场足球赛为研究对象,分析和归纳了观赛球迷的分布特征、活动特征,并进一步探索了球迷的行为对于球场周边商业体的影响,以此来分析大型赛事球迷的空间行为特征,希望能够对未来的城市相关设施规划起到一定的指导作用。研究表明,球迷的分布涵盖市域、呈现类圈层结构。球迷的出发时间与球赛开始时间相关,大部分球迷的出行目的较为明确。球迷对于球场周边一定距离范围内的商业体有影响,且商业体距离球场越远,影响越弱。最后,对于手机信令数据在大型活动或特定人群特征分析方面的应用提出了一些讨论思考。     

Identifying a technological style in the making of lime plasters at Teopancazco (Teotihuacan,México)

The aim of this article is to focus on the technology of archeological plasters at Teotihuacan (Central Mexico), from the Classic Period (200–650 A.D.), focusing in the study of Teopancazco, a neighborhood center in the city. Petrographic and chemical analyses by OM, SEM-EDS, and LA-ICP-MS were conducted to characterize samples from different constructive phases and sectors of the neighborhood center, to determine the provenance of the raw materials employed in the manufacturing (e.g., volcanic glass shards) and to assess whether a shift occurred in the manufacturing of plasters and in the procurement strategies of raw materials during the different phases. The results of the analyses show that almost no changes occurred in the making of the plaster during more than four centuries and allow us to consider the presence of a technological style in their manufacture, which is characterized by the making of plaster by mixing lime with volcanic glass shards, which in the case of Teopancazco were derived from the Altotonga (Veracruz) magmatic system. The data at our disposal suggest that this style was developed in Teopancazco and later introduced throughout the city of Teotihuacan in the Early Xolalpan phase (A.D. 350), although we still do not know whether the provenance of the raw materials is the same. The wide distribution of this technological tradition could be due to the technological properties of the materials and/or the influence of the intermediate elite who ruled over Teopancazco. The paper confirms that the study of material culture and technology sheds light on broader cultural aspects of ancient societies.     

Social distance,ethnicity, and religion in Northwest China: a survey of inter- and intra-group attitudes among Han,Hui, and Tibetan students

Building on existing research concerned with social distance in multi-ethnic states, this study of college students in Gansu Province and Ningxia Hui Autonomous Region provides a picture of social attitudes, intra-group attachment, and inter-group social distance along ethnic and religious lines in Northwest China. The study measures inter-ethnic group fissures in Chinese society as measured in social distance between three ethnic groups: Han, Hui, and Tibetan. Comparative survey methods are used to examine inter- and intra-group relations by mapping dimensions of social distance among 382 university students. Our results indicate only very subtle differences that suggest a closer majority–minority relationship than the previous literature indicates, especially between the Hui and Han. The findings show some clustering and segregating patterns along ethnic lines, specifically when accounting for degrees of trust and tolerance and levels of ethnic and religious attachment. The Hui and Han in Ningxia exhibit closer inter-group relations in comparison to wider measurements of social distance between the Tibetan and Han in Gansu. Where the survey data revealed clustering among ethnic groups, the analysis shows that religious, geographical, and economic differences fail to account for the attitudinal differences between ethnic groups.     

Geography's secret powers to save the world

The purpose of this paper, prepared to present at the 2018 joint Canadian Association of Geographers (CAG) and International Geographical Union (IGU) regional conference, is to suggest three strategies, framed as proposals, that geography and geography education can deploy to “save the world.” The first proposal is to expand explicit instruction in spatial thinking to close gender‐based achievement gaps. The second proposal is to apply research from the learning sciences to develop persuasive geography curricula and instructional materials. The third proposal focuses on ways social media and geospatial technologies can be employed in civic education, an idea termed “spatial citizenship.” The paper suggests a re‐envisioning of geography education with an enhanced focus on teaching for, in, and about a world that fully appreciates difference and acts on that appreciation.     

An Insider's Look into Policy Transfer in Transnational Expert Networks

Much of the recent academic literature on spatial planning in Europe focuses on either cross-national comparison of planning frameworks and planning practices or on transnational and transregional initiatives and their impact on planning in European countries. From those publications, it can be gleaned how similar themes are translated differentially in different national contexts. Although it is also a great source of European integration and harmonization, the phenomenon of the knowledge exchange within transnational expert networks of European planners at the level of cities has received less attention. In this paper, the knowledge exchange among planners in such a network is studied, highlighting the role of “transfer agents” (academic and/or policy experts operating in communities in different policy arenas) in the exchange process. It builds on the insights from existing literature on policy transfer and policy learning, and tries to add a new perspective on this body of literature from an insiders' perspective, i.e. participatory observation. The idea is that policy transfer can be fruitfully approached as a process of knowledge and information transfer between producers, senders, facilitators and recipients. Often this exchange is to a very large extent a process of absorbing appealing labels for policy solutions from the international or national policy levels, and then adopting an interpretation of it suitable to one's own context. The authors try to give meaning to this exchange process by using two mechanisms, i.e. social interaction and conceptual replication. By combining these two mechanisms the authors try to uncover which policy lessons are being transferred among seven European cities that joined the expert network on European sustainable urban development (Pegasus).
