政治对城市规划的作用机制与影响

城市规划受政治制约，政治对城市规划的作用机制实际上在于权力和利益对城市空间和土地的处置权。权力从方向、层次和时间性三个方面影响城市规划的作用机制，城市规划进行分配与控制的目的在于平衡各种要素所形成的权力结构。城市规划的实现要依靠不同的规划师队伍站在政治的高度进行最有效的合作。     

全球时间与岭南想象 历史与大众政治视野中的广州新建筑评述

Tents,Tweets, and Events: The Interplay Between Ongoing Protests and Social Media

Recent protests have fuelled deliberations about the extent to which social media ignites popular uprisings. In this article, we use time‐series data of Twitter, Facebook, and onsite protests to assess the Granger causality between social media streams and onsite developments at the Indignados, Occupy, and Brazilian Vinegar protests. After applying Gaussianization to the data, we found contentious communication on Twitter and Facebook forecasted onsite protest during the Indignados and Occupy protests, with bidirectional Granger causality between online and onsite protest in the Occupy series. Conversely, the Vinegar demonstrations presented Granger causality between Facebook and Twitter communication, and separately between protestors and injuries/arrests onsite. We conclude that the effective forecasting of protest activity likely varies across different instances of political unrest.     

Informed Citizenship in a Media‐Centric Way of Life

Two trends are prominent and universal to contemporary democracies: Voting rates are in steady decline while media use is growing. A transdisciplinary vantage point might help to redirect research trajectories that lead to alarming conclusions of democratic crisis. To that end, dominant ontological positions will need revision or perhaps replacement. This essay calls for (a) knowledge to be explicated beyond the written word, with serious consideration of the information value of images in the conceptualization of informed citizenship; (b) the deliberate entanglement of emotion with knowledge acquisition and political participation in explication and operationalization of active citizenship; and (c) reconsideration of electoral activities as the index of active citizenship, especially in the context of interactive media.     

Insta-echoes: Selective exposure and selective avoidance on Instagram

Many studies have examined the degree to which social media facilitate echo chambers that keep users from diverse political perspectives (Bakshy, Messing, & Adamic, 2015; Parmelee & Bichard, 2012; Zhu, Skoric, & Shen, 2017). The present study expands the debate regarding selective exposure and selective avoidance to political Instagram use. A survey of politically active Instagram users measured how often users expose themselves to opinion-reinforcing political leaders and the extent to which users avoid opinion-challenging leaders. The findings indicate a high level of selective avoidance behavior on Instagram, especially by users who are conservative, Republican, very ideological, and female.     

Resisting Urban Entrepreneurialism: Place-based Politics in the Production of Collective Identity

Urban entrepreneurialism reflects recent changes to economic and political sensibility and emphasises the regulation of urban space in ways that promote market-based approaches to the restructuring of the built environment. The contradictions and controversy surrounding the Mt Barker foundry and the Pelican Point power station in South Australia provide an opportunity to revisit the place of urban social movements in this 'entrepreneurial' politic of a state Liberal government in the late 1990s.     

Towards democratic planning? Negotiating change in St Kilda,Melbourne

Are planners ‘dealmakers’ caught up in selling urban areas to the highest bidder, or are they negotiators concerned to maintain democratic planning and social diversity in areas that are subject to gentrification? This paper explores this question through the example of two sites in St Kilda, Melbourne. The sites highlight planning strategies used at the local government level by planners who are attempting to negotiate change and to maintain the social and cultural diversity of the area. The first example illustrates the processes of ‘democratic planning’ where planners question what is ‘legitimate’ and draw on discourses of local need. The second example illustrates the problems of co‐opting local culture within a process of democratic planning that is based on community consultation. Together, the examples illustrate the need for tighter local government policies, including stricter policies about the use of developer contributions, and a closer and more critical focus on the term ‘community consultation’, if democratic planning is to be achieved.

Environment and colour: The technological interface

Technology and colour are viewed as interfaces between the environment, humans and human activity. Examples are provided of ways of facilitating and improving access to and use of colours by commercial users of colour coatings through improvements in the accuracy of measuring and displaying colour. By analogy, the task of providing effective interfaces within the coatings industry, between the coatings industry and the environment and between the coatings industry and the public and political domain are discussed. Examples of information shortfalls are cited to illustrate how distortions arise. Examples of more effective, integrated technological, organisational and political interfacing are culled from the author's experiences.
