后乡土社会视角下农民集中居住区秩序重建及反思--基于苏北的实证调查北大核心SSCI

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。     

论活力社会建设

改革开放在一定意义上是中国社会转向活力社会的一个重要标志。所谓活力社会就是充满生机活力的社会,每个社会细胞都健康活跃,这样的活力社会必然是开放、自由、包容和创新的社会。使社会始终充满生机活力,是我国国家制度和国家治理体系的一个显著优势,今后不但要继续发挥好这个显著优势,而且要将大力建设活力社会纳入国家发展战略,转化成为一项自觉的社会行动。当前,我国已全面建成小康社会,正在开启全面建设社会主义现代化国家新征程。在这一新时代背景下,明确提出、提倡并大力建设活力社会尤其具有重大的现实意义和深远的时代意义。     

The effects of four different solvent vapours on the restoration of obliterated stamp markings from five different wooden surfaces

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.
