Sanitation workers at the frontline: work and vulnerability in response to COVID-19

ABSTRACT

The absence of a vaccine and effective treatment for COVID-19 has created public panic and burdened the health systems in most countries. Along with health workers’, sanitation personnel are also working at the frontlines in the war against the disease by keeping cities clean. Sanitation workers are engaged in Drudgery, Dangerous, Dirty and Dehumanising work that makes them vulnerable for developing the chronic respiratory diseases due to the exposure of various hazardous materials and toxic gases that are emitted from the solid waste. The sanitation workers working on a contractual basis are excluded from the labour policies and welfare programs who are playing a vital role in fighting the pandemic. Women sanitation workers are even more vulnerable because most of them are non-literate, poor in financial management and under-represented in the sanitation employee’s union. The local and state governments should protect and safeguard sanitation workers by providing them with adequate protective equipment, ensure payment of paying adequate salaries and provide them with health insurance.     

对中国城市环境地质工作的思考

本文回顾了国内外城市地质工作的发展历程，阐述了中国城市地质工人的发展方向和重点工作领域。指出城市地质工作必须服务于城市（城市群，经济开发区）的规划，建设和管理，为城市社会经济可持续发展，减灾防灾提供具有针对性，实用性和超前性的基础地质资料和成果。由于中国城市的规模，性质，自然资源承载力，地质环境特征不同，城市环境地质调查，评价的对象，内容也将有所差异。归纳起来，城市地质的重点工作领域为：城市可持续发展，城市可持续发展的资源开发战略与对策，城市地质环境容量及脆弱性分析。城市地质灾害：城市地质灾害风险，影响面，易损性及对灾害的反应，城市环境变化的地质指标体系，城市环境地质综合研究：城市环境地质调查评价的新理论，新方法，新技术，城市环境地质图纱的编制。数字城市环境地质：GIS平台上的地质空间数据库，城市地质环境动态分析，评价，决策系统和地质灾害预警预报系统。     

建设项目"三同时"制度中存在的问题及分析

本文就我国“三同时”制度实施中存在的问题进行了较全面的剖析，并针对这些问题提出了解决的办法，为我国进一步完善“三同时”制度，拓展“三同时”管理的内涵，制订有关“三同时”管理细则提供了有价值的参考。     

山地城市排水管网特细颗粒物特性及变化规律

对山地城市排水管网中特细颗粒物的粒径分布特征及变化规律、Zeta电位分布特征及变化规律和ρ(SS)的变化规律进行研究,同时对相关水化学参数(如电导率、pH)的变化规律进行了分析.结果表明:特细颗粒物的平均粒径、Zeta电位、ρ(SS)和电导率分别为21.04～73.53μm、-20.83～-11.15 mV、106～492 mg/L和973～2 445μS/cm,其统计平均值分别为(43.74±14.12)μm、(-17.95±1.88)mV、(233±90)mg/L和(1 343±331)μS/cm;pH为7.25～7.63.工业废水的排入对排水管网特细颗粒物的粒径分布特征、Zeta电位分布特征以及电导率有显著的影响并呈现出一定的规律性;传统沉砂池对进水中特细颗粒物的去除能力相当有限,特细颗粒物会直接进入生物处理系统.      

Ecological literacy and beyond: Problem-based learning for future professionals

Ecological science contributes to solving a broad range of environmental problems. However, lack of ecological literacy in practice often limits application of this knowledge. In this paper, we highlight a critical but often overlooked demand on ecological literacy: to enable professionals of various careers to apply scientific knowledge when faced with environmental problems. Current university courses on ecology often fail to persuade students that ecological science provides important tools for environmental problem solving. We propose problem-based learning to improve the understanding of ecological science and its usefulness for real-world environmental issues that professionals in careers as diverse as engineering, public health, architecture, social sciences, or management will address. Courses should set clear learning objectives for cognitive skills they expect students to acquire. Thus, professionals in different fields will be enabled to improve environmental decision-making processes and to participate effectively in multidisciplinary work groups charged with tackling environmental issues.

A narrative perspective on institutional work in environmental governance – insights from a beach nourishment case study in Sweden

Institutional work offers a promising lens for understanding institutional change, focusing on the efforts of actors in creating, maintaining or disrupting institutions. In this paper, we explore the capacity of a narrative approach to provide insights on institutional work, using a case study from the coast of Sweden. We identify four narratives that compete in the policy discourse regarding erosion and beach nourishment in the coastal province of Scania. The narratives reveal that actors hold different beliefs concerning the magnitude of the erosion problem, the division of responsibilities and the suitability of sand nourishment as a coastal protection measure. The narrative competition is considered reflective of past institutional discussions and ongoing institutional work in coastal management in Scania, confirming that narratives are used as sense-making and meaning-giving devices in institutional discussions.     

施工现场的风险管理应用研究

风险管理理论已广泛应用于项目的设计、采购及施工等各个阶段。在建设项目施工阶段的应用,特别是在施工事故的主动预防领域的应用,国外企业已取得不少成效。通常建设项目的施工现场由一系列的土建、安装、试验等施工活动组成,每一项施工活动又分解为不同的施工步骤,各施工步骤之间又存在多种工艺关系或组织关系,结合这些关系的特点,如果能对每一步骤中存在的危害进行识别、评价并根据评价结果采取相应的控制措施,则整项施工活动的风险可以从"源"上消除或降低到可接受程度,从而实现安全。针对施工现场施工活动多样、人员流动性大等特点,通过对施工现场的风险管理的应用研究,以期为各级从事现场的管理技术人员提供一种便于现场进行施工风险控制的实践方法。
