从对航空及航运的影响、通行能力和行车舒适性、行车安全与气候适应性、施工难度及工程风险等方面对桥梁、隧道方案各自的技术特性进行了分析与比较。从技术角度考虑,桥隧方案皆具有实施的可行性,隧道在航运影响、气候适应性、生态环境等方面明显优于桥梁,而桥梁则在通行能力、施工难度和风险、运营成本、行车安全、行车舒适性、景观效果等方面优于隧道。随后,运用层次分析法建立了渤海海峡跨海通道比较评价的指标体系,并确定了各指标的权重系数。通过专家打分法和隶属度函数取得各定性指标和定量指标的隶属度,最后运用模糊综合评价模型计算全桥梁、全隧道及桥隧组合方案的模糊综合评价值,全隧道方案评价得分最高,因此,推荐渤海海峡跨海通道采用全隧道方案。

根据独头巷道作业空间的特点,给出了独头巷道局部空气年龄、平均空气年龄的定义及其计算模型,用示踪气体测定平均空气年龄的方法和原理,并用CFD (computational fluid dynamics)对独头巷道附壁受限射流通风流场及平均空气年龄进行了数值计算,得出了独头巷道空间通风流场和平均空气年龄分布,建立了计算换气效率和排污效率的数学模型。研究表明影响通风有效性的主要因素是空气年龄和污染物浓度,而影响空气年龄主要是通风气流组织和通风量。为评价独头巷道通风有效性提供了一种新的理论依据。

This study aims to explore the prevalence and determinations of physical inactivity among hospital employees in Shanghai, China. A cross-sectional study of 4612 employees aged 19 to 68 years was conducted through stratified cluster sampling from different classes of Shanghai hospitals in 2011. The total physical activity was evaluated using the metabolic equivalent according to the Global Physical Activity Questionnaire. Among the participants, 38.5%, 32.3%, and 64.6% of the employees are inactive at work, commuting, and taking leisure time, respectively. Up to 41.8% of the men and 37.8% of the women (P = 0.012) are physically inactive. When the age and educational level are adjusted, male doctors and medical technicians show a higher percentage of physical inactivity than male workers in logistics (P = 0.001). Among females, employees who are working in second- and third-class hospitals show a higher proportion of physical inactivity than those who are working in community health care centers. Logistic regression analyses show that the odds ratios (ORs) of leisure-time physical inactivity associated with the intensity of physical activity at work are 2.259, 2.897, and 4.266 for men (P<0.001) and 2.456, 3.259, and 3.587 for women (P<0.001), respectively. The time during commuting activities is significantly associated with leisure-time physical inactivity in either sex (OR= 2.116 for men and 2.173 for women, P<0.001). Hospital employees, particularly doctors and medical technicians, show a higher proportion of physical inactivity than other inhabitants in Shanghai. The time and intensity of activity at work and commuting are associated with leisure-time activities.

River Chief System (RCS): An experiment on cross-sectoral coordination of watershed governance
Longfei Wang, Jiaxin Tong, Yi Li

The trans-regional characteristics of watershed governance produce more problems beyond the capacity of each individual water-related department, leading to the fragmentation of watershed management. The River Chief System (RCS) has experienced swift developments over the past decade in China by appointing the local government heads as river chiefs. RCS works efficiently in the short-term due to its superiority in the inclusion of clear responsibility, authority, and multi-sectoral collaboration. However, the characteristics of the authority-based vertical coordination of the hierarchical system remain unchanged, and therefore the problems of organizational logic and the responsibility dilemma still exist. Tasks including perfecting of laws, integrated watershed management, and public participation still need to be completed. RCS reflects the routine and characteristics of the migration of national governance, and as such provides new insights for other developing countries in the design of river management systems.
