New frontiers facing urban sociology at the Millennium

The article examines some of the major challenges facing urban sociology at century's end given its traditions and lineages. These challenges arise out of the intersection of major macrosocial trends and their particular spatial patterns. The city and the metropolitan region emerge as one of the strategic sites where these macrosocial trends materialize and hence can be constituted as an object of study. Among these trends are globalization and the rise of the new information technologies, the intensifying of transnational and translocal dynamics, and the strengthening presence and voice of specific types of socio‐cultural diversity. Each one of these trends has its own specific conditionalities, contents and consequences for cities, and for theory and research. Cities are also sites where each of these trends interacts with the others in distinct, often complex manners, in a way they do not in just about any other setting. The city emerges once again as a strategic lens for the study of major macrosocial transformations as it was in the origins of sociology. Can urban sociology address these challenges and in so doing once again produce some of the analytic tools for understanding the broader transformation?     

The quest for legitimacy and the communication of strategic cross-sectoral partnership on Facebook: A big data study

Nowadays, many wicked problems such as environmental issues require organizations from multiple sectors to form cross-sectoral alliances. Cross-sectoral alliance networks can transfer resources and signal affiliations and value alignment between strategic partners. The communication of cross-sectoral alliances is a form of CSR communication that serves organizations’ strategic goals and objectives. Drawing on the literature on digital CSR communication and legitimacy theory, this article examines which legitimacy needs shape the formation of cross-sectoral ties on Facebook in addressing environmental and sustainable development issues in the United States. Combining data-mining, text-mining, social network analysis, and exponential graph modeling, this research investigates the structure of a network among 3071 organizations across multiple sectors. Findings show that organizations’ cross-sectoral tie formation is mainly driven by social legitimacy and alliance legitimacy needs.

Ranking terrorists in networks: A sensitivity analysis of Al Qaeda's 9/11 attack

All over the world, intelligence services are collecting data concerning possible terrorist threats. This information is usually transformed into network structures in which the nodes represent the individuals in the data set and the links possible connections between these individuals. Unfortunately, it is nearly impossible to keep track of all individuals in the resulting complex network. Therefore, Lindelauf et al. (2013) introduced a methodology that ranks terrorists in a network. The rankings that result from this methodology can be used as a decision support system to efficiently allocate the scarce surveillance means of intelligence agencies. Moreover, usage of these rankings can improve the quality of surveillance which can in turn lead to prevention of attacks or destabilization of the networks under surveillance.The methodology introduced by Lindelauf et al. (2013) is based on a game theoretic centrality measure, which is innovative in the sense that it takes into account not only the structure of the network but also individual and coalitional characteristics of the members of the network. In this paper we elaborate on this methodology by introducing a new game theoretic centrality measure that better takes into account the operational strength of connected subnetworks.Moreover, we perform a sensitivity analysis on the rankings derived from this new centrality measure for the case of Al Qaeda's 9/11 attack. In this sensitivity analysis we consider firstly the possible additional information available about members of the network, secondly, variations in relational strength and, finally, the absence or presence of a small percentage of links in the network. We also introduce a case specific method to compare the different rankings that result from the sensitivity analysis and show that the new centrality measure is robust to small changes in the data.     

网络传媒对协商民主的影响

在网络时代,网络传媒的运用,给协商民主的实现赋予了无限可能,提供了种种便利,它克服了传统公共领域中协商民主所存在的弊端,如话语权被掌握在少数人手中,也展示出了强大的生命力,引发了强烈的反响,使社会大众在更自由、更理性的协商基础上达成了共识。从协商民主的内涵入手,分析了网络传媒对协商民主的积极影响和消极作用,提出了完善网络环境下协商民主的对策和建议。
