风景园林与公共卫生：共识、分野与融汇 ——2次公共卫生革命视野下的学科关系审视

面对新型冠状病毒(COVID-19)所引发的肺炎疫情,基于“学科演进”这一特殊视角,关联性地审视“风景园林学”所面对的公共卫生和公众健康问题。在概述风景园林和公共卫生简史的基础上,重点结合第一次和第二次公共卫生革命,依据相关时间序列和历史事件梳理、勾勒出“风景园林-公共卫生”两大学科关联演进的大体脉络和历史图景。研究表明,正是第一次公共卫生革命,使现代风景园林和现代公共卫生从共识走向分野;而第二次公共卫生革命,又使现代风景园林和现代公共卫生从分野走向融汇。

FixMyStreet Brussels: Socio-Demographic Inequality in Crowdsourced Civic Participation

FixMyStreet (FMS) is a web-based civic participation platform that allows inhabitants to report environmental defects like potholes and damaged pavements to the government. In this paper, we examine the use of FMS in Brussels, the capital city of Belgium. Analyzing a total of 30,041 reports since its inception in 2013, we demonstrate how civic participation on FMS varies between the ethnically diverse districts in Brussels. We compare FMS use to a range of sociodemographic indicators derived from official city statistics as well as geotagged social media data from Twitter. Our statistical analysis revealed several significant differences between the districts that suggested that crowdsourced civic participation platforms tend to marginalize low-income and ethnically diverse communities. In this respect, our findings provide timely evidence to inform the design of more inclusive crowdsourced, civic participation platforms in the future.     

城市公共绿地开发经营模式探讨

城市公共绿地在城市居民生活中扮演重要角色,然而政府用于建设公共绿地的资金已越来越不能满足社会的需求.所以,笔者从城市绿地开发的概念入手,通过分析总结典型案例,提出几种新的城市公共绿地开发经营模式,发动私人力量,公私联合建设管理城市公共绿地,尽量使城市公共绿地建设与受益相挂钩,减轻政府负担,形成新的符合市场经济发展的开发经营体制.讨论了新的开发模式中政府的职能与义务,提出相应的开发程序,就几个成功案例进行了详尽的分析.

Risk of sick leave associated with outdoor air supply rate, humidification, and occupant complaints

We analyzed 1994 sick leave for 3,720 hourly employees of a large Massachusetts manufacturer, in 40 buildings with 115 independently ventilated work areas. Corporate records identified building characteristics and IEQ complaints. We rated ventilation as moderate (approximately 25 cfm/person, 12 ls-1) or high (approximately 50 cfm/person, 24 ls-1) outdoor air supply based on knowledge of ventilation systems and CO2 measurements on a subset of work areas, and used Poisson regression to analyze sick leave controlled for age, gender, seniority, hours of non-illness absence, shift, ethnicity, crowding, and type of job (office, technical, or manufacturing worker). We found consistent associations of increased sick leave with lower levels of outdoor air supply and IEQ complaints. Among office workers, the relative risk for short-term sick leave was 1.53 (95% confidence 1.22-1.92) with lower ventilation, and 1.52 (1.18-1.97) in areas with IEQ complaints. The effect of ventilation was independent of IEQ complaints and among those exposed to lower outdoor air supply rates the attributable risk of short-term sick leave was 35%. The cost of sick leave attributable to ventilation at current recommended rates was estimated as $480 per employee per year at Polaroid. These findings suggest that net savings of $400 per employee per year may be obtained with increased ventilation. Thus, currently recommended levels of outdoor air supply may be associated with significant morbidity, and lost productivity on a national scale could be as much as $22.8 billion per year. Additional studies of IEQ impacts on productivity and sick leave, and the mechanisms underlying the apparent association are needed.
