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

虽然我们可以回顾性地观察到规划科学中的热点问题的唐斯，但问题关注周期在该领域还没有得到全面和系统的分析。这是本研究项目的出发点。它涉及的基本问题是如何在空间规划的科学话语的问题演变。以“气候变化”和“收缩的城市”为例，对规划科学中的问题关注周期进行了实证研究。在现有的科学社会学方法的基础上，关注周期被概念化为基于阶段启发的社会决定的发展过程。在话语分析的框架内，研究了专业话语中各个问题在时间过程中的意义变化。此外，社会结构和过程的问题注意力周期进行检查。网络分析描述了各自领域的主动和被动行为体景观的具体情况，在此基础上，机构分析考虑了网络行为体行动的结构背景。该研究项目旨在通过描述公众处理规划科学问题的复杂过程和确定关键影响因素，加深对规划科学问题关注周期的理解。

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.
