随着乡村振兴战略全面实施及新农村建设深入推进,人口、产业、生态等资源要素在城乡互惠流动的同时,传统乡土性逐渐消解式微,如何重塑后乡土社会地域认同及整合机制是农民集中居住区重建的关键。基于后乡土社会理论视角,从地域空间、组织体系及社会结构维度考察苏北农民集中居住区秩序重建的实践过程发现,完成物理空间整合的农民集中居住区依然不同程度延续着传统乡土社会整合机制,使得现代普遍主义价值取向的地域关联及社会认同机制难以有效建立,后乡土社会样态的农民集中居住区公共性重建缺乏必要的社会基础。因此,如何突破制度红利型动力机制及行政主导实践逻辑重塑后乡土社会整合机制,就成为农民集中居住区重建地域公共性并顺利过渡到社会生活共同体的关键。 相似文献

The stamp markings on wooden surfaces, which are placed on trees and products including antiques, indicate the status of trees and involve identifying data regarding the products. Such markings are obliterated either to facilitate illegal logging or to conceal product information. Despite the wide literature on the restoration of obliterated characters on metal and polymer surfaces, the recovery of defaced characters on wooden surfaces appears to be understudied. Several reference texts in the forensic marks’ examination literature suggest that water, water vapor, and alkaline solutions are useful in restoring the abraded markings on the wood. Since there does not seem to be any experimental study proving such success, this study aimed to fill this gap. This study conducted experimental research by using water, ethanol, ammonia, and chloroform to recover the scraped characters on samples obtained from walnut, beech, spruce, oak, and cedar trees. The cold-stamped characters, which were defaced at varying depths, were restored using vapor and liquid phases of four solvents. While the vapor phases of water, ethanol, and ammonia yielded good outcomes on all types of wooden surfaces, the liquid phases did not seem to be useful in the revisualization process. The response of the vapors, which varied between 62 and 220 s, depended on the type of wood. The restoration technique developed in this research offers the possibility of on-site usage, easy application, utilization of low-cost solvents, rapid recovery, and effectiveness on various wooden surfaces. Overall, the restoration methodology used in this research appears to be fruitful in retrieving identifying information on wooden samples. 相似文献
