长株潭城市群产业协同度测度及影响因素研究

城市群是城市化发展到高度水平的产物,在城市群发展过程中,产业结构发展状态直接关系到城市群的可持续发展。长株潭城市群于1997年正式开始规划建设,发展至今,三市在融合发展上取得了较好的成效,但也存在着产业结构相似导致区域内部竞争、行政区域划分弱化合作机制、传统产业比重过大而高新技术产业发展较慢等问题。针对这些问题,利用熵权法计算长株潭城市群和长株潭三市三次产业发展的有序度,并建立复合系统模型计算长株潭城市群和长株潭三市的产业协同度,再利用随机效应模型分析长株潭城市群产业协同度的影响因素。结合产业协同发展的影响因素,提出加强产业结构规划、加强合作机制建设、完善市场资源配置等建议,以不断优化长株潭城市群产业协同。     

Connecting sleep,the neurocognitive memory system,and Bourdieu's habitus concept: Is sleep a generative force of the habitus?

Bourdieu's habitus theory has been criticized for allegedly being static and deterministic. This is partly due to insufficiently elaborated microstructural aspects of the habitus. Previous works have tried to elaborate the habitus' individual side by drawing on neuropsychological and neuroscientific concepts including the neuropsychological memory system. Despite its relevance for several social processes, sleep has not been considered in this context. The present work investigates the interrelatedness of habitus, sleep, and the memory system with particular focus on the determinism and staticity critique. It shows that the neuropsychological memory system overlaps largely with implicit memory and sleep plays an important role in the formation of habitus‐relevant memory. Moreover, sleep enhances processes such as memory consolidation, reflexivity, associative creativity, and dream‐associated simulation of unknown situations which counter the determinism and staticity critique. The present article argues that habitus, memory, and sleep are closely related and memory and sleep represent operational micro‐structures of the habitus. Moreover, sleep‐related processes represent a generative force that renders the habitus more dynamic. Finally, strengths and weaknesses of the habitus‐memory‐sleep nexus are discussed and further lines of research are outlined.
