Schole facilitates the exchange of scholarly insights and scientific discovery

面对现代性的环境风险，科学界和政策界对环境科学研究投入大量的政治、经济、文化资源，同时也为环境风险治理的专业知识积累作出重要贡献，但专业知识能否给予行动以强有力支持则成了一个问题。分析发现，适度的改变是不够的，需要对社会体制进行不断优化与创新。基于此，本文在梳理环境专业知识核心概念与内涵的基础上，探索性地提出以反思性、批判性、建构性为主要分析维度的社会科学中环境专业知识的整体责任框架，凸显社会科学的专业知识在具有高度复杂性和不确定性的环境风险社会中发挥的融合作用，为实现可持续性的社会变革创制新的超越式的战略性发展模式。

特定词汇的风靡承载着深刻的社会内涵，从“下海”到“上岸”的话语变迁，折射出不同时代个体在机遇与风险间的集体选择。本研究以Lakoff和Johnson的认知隐喻理论为基础，梳理从下海到上岸的含义变迁，解析结构、方位与本体隐喻，并开展英文语境跨文化比较。研究发现，“上岸”依托“不稳定是苦海”的结构隐喻、具身性方位隐喻与目标导向的本体隐喻，构成认知安稳与风险的核心框架；作为植根中国农耕文明的本土隐喻，“上岸”隐喻与社会求稳取向高度契合，在英文中缺乏直接对应表达；中西“海—岸”隐喻差异本质是农耕文明求安与航海文明求拓的价值分野。研究丰富了认知隐喻理论的本土应用，为解读社会转型期集体心态与跨文化比较提供了新视角。

Rapid urbanization is driving a surge in decoration and demolition waste (DDW), yet DDW generation and management remain insufficiently characterized in China. Using a single office-building project in Shenzhen as an exploratory case study, we quantify DDW composition and waste generation rates (WGRs) from on-site inspections, semi-structured interviews, and project records (material catalogues, construction organization plans, and bills of quantities) using a unit-area approach. Total DDW intensity is 382.74 kg/m². Mortar and concrete account for 38% and 32% of total mass, respectively; together with metals, tiles, and bricks, these fractions contribute ~90% of DDW, indicating strong concentration in a few material streams and the need for differentiated controls. Comparison with prior studies suggests that WGRs and composition are sensitive to local waste-management systems, managerial awareness, and construction practices. Given the single-case design, the reported WGRs should be interpreted as indicative rather than statistically representative benchmarks. Based on the empirical results, we propose an integrated governance framework combining improved laws and standards, strengthened supervision and traceability, targeted economic incentives, optimized collection and sorting systems, upgrading of recycling facilities, and capacity building through training and public education.
