Issue Attention Cycles in Planning Science. A Discourse and Network Analysis using the Examples of "Climate Change" and "Shrinking Cities"

虽然我们可以追溯到规划科学中热门话题的起伏，但问题注意周期在这一领域还没有得到全面和系统的分析。这就是本研究项目的出发点。它涉及关于空间规划的科学论述中的基本问题如何演变。以“气候变化”和“城市缩水”为例，对规划科学中的问题关注周期进行了实证研究。在科学问题社会学现有方法的基础上，注意周期被概念化为在阶段启发式基础上由社会决定的发展过程。在语篇分析的框架内，我们考察了专业语篇中各个问题在一段时间内的意义变化。此外，还考察了问题注意周期的社会结构和过程。网络分析描述了各自领域中主动和被动行为者环境的具体情况，并且在此基础上，机构分析将网络行为者行动的结构背景考虑在内。该研究项目旨在通过描述规划科学中公众处理问题的复杂过程和确定关键影响因素，使人们能够更深入地了解规划科学中的问题注意周期。

Although we can retrospectively observe the ups and downs of hot topics in planning science, yet issue attention cycles have not been subject of a comprehensive and systematic analysis in this field. This is the starting point of this research project. It deals with the basic question how issues evolve in the scientific discourse on spatial planning. Using the Examples of "Climate Change" and "Shrinking Cities", issue attention cycles in planning science are examined exemplarily. Building on existing approaches of the sociology of science issue attention cycles are conceptualized as socially determined development processes on the basis of a phase heuristic. In the frame of a discourse analysis the changing meaning of the respective issue in the professional discourse in the course of time is examined. In addition, social structures and processes of the issue attention cycle are examined. A network analysis describes a specific picture of the active and passive actor landscapes in the respective field and, based on this, an institutional analysis takes the structural context of actions by the network actors into consideration. The research project aims at enabling a deeper understanding of issue attention cycles in planning science by describing the complex processes of the public treatment of issues in planning science and by identifying key impact factors.
