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.

怀旧的意识形态一方面深受时代政治、社会经济和集体情绪等多方影响，另一方面又对现实社会产生巨大影响。景观理论、符号政治经济学批判和文化唯物主义理论揭示了消费社会中的怀旧被资本主义意识形态控制、利用及发挥文化代偿的功能，从而导致多重社会危机的现实状况。以历史唯物主义为视角重审怀旧的意识形态，可见其生成源自统治阶级对社会意识形态的控制，其引发的社会危机需要从怀旧的意识形态自身和现实政治经济变革两方面进行解决。将怀旧置入历史之流，可见其价值导向既表现出维护现存社会秩序的一面，又展现出解构资本主义意识形态的可能，具有双重的历史性意义。

Household income frequently accounts for family economic stability and total quality of life. This study examines the relationship between household income and the age at which the husband is older than the wife (AHOW). The findings indicate an inverted U relationship between AHOW and household income, suggesting that a greater age difference between the couple may not increase income and may even decrease it. It indicates that age differences should be carefully considered when selecting a partner. It suggests that, from an income-optimization perspective, the man might avoid marrying a wife considerably younger than himself.
