“竞争申请制”:可持续发展政策试点与央地关系重构

可持续发展目标(SDGs)的提出,开启了人类可持续发展领域最宏大的政策实验,也为开展国际视野的比较公共政策研究提供了难得机遇。执行SDGs及国家可持续发展政策需要处理好中央政府与地方政府间关系,而政策试点是协调这一关系的重要政策工具。已有文献对经济政策试点做了较充分的研究,然而对旨在实现经济、社会与环境协调的可持续发展政策试点,现有研究尚缺乏成型理论。在复杂央地关系格局下,对于需持续投入成本且成果难以界定的可持续发展政策试点,其具有怎样的不同于经济政策试点的机制?此外,众多西方学者将美国作为政策试点研究的制度基础并视其为“民主实验室”。然而,政策试点在以中国为代表的不同体制国家中同样存在,并以多样的机制发挥作用。那么,不同国家体制内的可持续发展政策试点又有哪些异同?政策试点影响下中国既有的央地关系发生了怎样的重构?对此,本文基于最典型案例原则,选取中国与美国响应SDGs分别开展的政策试点进行比较研究。笔者识别了不同体制下试点机制的异同,指出中国基于“竞争申请制”开展的可持续发展政策试点强化了中央部委与地方政府间关系,形成了地方官员的可持续发展激励,保障了政策试点的实施。

环境监测在环境保护中起着重要的作用,伴随着环境保护法的进一步落实,使我国的环保措施及标准有了越来越规范的准则。可从实际工作情况看,监测机构监测水平较低、设备滞后、监督不严格等问题依然存在因此,要全面提高环境监测水平,加大对环境监测工作的重视程度。本文主要以环境监测在生态环境保护中产生的作用入手,提出了一些完善措施。     

Quantifying progress toward a conservation assessment for all plants

The Global Strategy for Plant Conservation (GSPC) set an ambitious target to achieve a conservation assessment for all known plant species by 2020. We consolidated digitally available plant conservation assessments and reconciled their scientific names and assessment status to predefined standards to provide a quantitative measure of progress toward this target. The 241,919 plant conservation assessments generated represent 111,824 accepted land plant species (vascular plants and bryophytes, not algae). At least 73,081 and up to 90,321 species have been assessed at the global scale, representing 21–26% of known plant species. Of these plant species, at least 27,148 and up to 32,542 are threatened. Eighty plant families, including some of the largest, such as Asteraceae, Orchidaceae, and Rubiaceae, are underassessed and should be the focus of assessment effort if the GSPC target is to be met by 2020. Our data set is accessible online (ThreatSearch) and is a baseline that can be used to directly support other GSPC targets and plant conservation action. Although around one‐quarter of a million plant assessments have been compiled, the majority of plants are still unassessed. The challenge now is to build on this progress and redouble efforts to document conservation status of unassessed plants to better inform conservation decisions and conserve the most threatened species.     

A hybrid decision-making approach based on FCM and MOORA for occupational health and safety risk analysis

IntroductionWith the development of industries and increased diversity of their associated hazards, the importance of identifying these hazards and controlling the Occupational Health and Safety (OHS) risks has also dramatically augmented. Currently, there is a serious need for a risk management system to identify and prioritize risks with the aim of providing corrective/preventive measures to minimize the negative consequences of OHS risks. In fact, this system can help the protection of employees’ health and reduction of organizational costs. Method: The present study proposes a hybrid decision-making approach based on the Failure Mode and Effect Analysis (FMEA), Fuzzy Cognitive Map (FCM), and Multi-Objective Optimization on the basis of Ratio Analysis (MOORA) for assessing and prioritizing OHS risks. After identifying the risks and determining the values of the risk assessment criteria via the FMEA technique, the attempt is made to determine the weights of criteria based on their causal relationships through FCM and the hybrid learning algorithm. Then, the risk prioritization is carried out using the MOORA method based on the decision matrix (the output of the FMEA) and the weights of the criteria (the output of the FCM). Results: The results from the implementation of the proposed approach in a manufacturing company reveal that the score at issue can overcome some of the drawbacks of the traditional Risk Priority Number (RPN) in the conventional FMEA, including lack of assignment the different relative importance to the assessment criteria, inability to take into account other important management criteria, lack of consideration of causal relationships among criteria, and high dependence of the prioritization on the experts’ opinions, which finally provides a full and distinct risk prioritization.     

土压平衡矩形顶管施工引起的地表沉降规律研究

为了分析与掌握矩形顶管施工引起的地表沉降变形规律，提出基于MIDAS-GTS有限元软件的分析方法，首先，通过工程实例验证MIDAS-GTS有限元软件在分析顶管施工引起地表沉降变形的有效性；其次，通过影响因素的敏感性分析确定不同影响因素作用下的地表沉降变形特性，这些影响因素主要包括开挖面支护压力、侧摩阻力、地层结构特性等；最后，通过地表沉降变形特性分析得出矩形顶管的适用范围。研究结果表明:基于MIDAS-GTS有限元软件的地表沉降规律分析方法和结果，可为矩形顶管施工过程提供相关参考和借鉴。     

基于社会技术系统的复工企业疫情防控风险路径研究*

为对复工企业疫情防控中的风险致因因素进行分析，探寻复工企业疫情防控的风险路径，基于社会技术系统理论，建立宏观工效学模型，通过查阅并分析国家、地方政府、企业文件以及相关文献，从人员、技术、组织管理、内部环境及外部环境5个子系统出发，识别出16个复工企业疫情失控致因因素；运用社会网络分析（SNA）构建复工企业疫情防控关系网络，对各因素节点中心度进行计算，分析各节点在网络中的位置及影响程度；采用贝叶斯网络（BN）进行参数学习和推理学习，找出复工企业疫情失控的最大致因链。结果表明:复工企业疫情失控关系网络中，存在政府监督管理不力→防疫物资筹备不足→日常监管不到位，政府监督管理不力→ 防疫宣传、培训缺失→员工防疫知识欠缺，政府监督管理不力→防疫宣传、培训缺失→日常监管不到位3条最长风险路径。研究结果可帮助复工企业针对最长风险路径中的因素进行管理，从而有效地为复工企业防疫提供理论支持。

污水处理消毒技术及发展方向

水循环过程中因受自然因素和人类的生活生产活动的影响,杂质和异物带入水循环形成污水。污水主要包括城市生活污水、工业废水和径流污水。若这些污水若不经处理就排入地面水体,就会使河流、湖泊受到严重污染。污水经过二级处理后,仍可能有病原菌,因此必须对污水进行消毒。本文分析比较了紫外线消毒以及氯消毒技术的适用条件、优缺点,还比较分析比较了二氧化氯消毒以及臭氧消毒技术的适用条件与优缺点,并对污水消毒技术的发展方向进行了探讨。
