Is Agriculture in Need of Ethics?

The minister of Agriculture, Nature Management andFisheries of the Netherlands reflects on the question``Is agriculture in need of ethics?'' Changingnorms and values in society, the influence of newtechnologies (such as biotechnology) and theinternational trade liberalisation (WTO) providearguments for a positive answer on this question.     

生态恢复过程中的种群遗传学考虑

生态恢复是生态科学的最终实验,从种群角度看,恢复的目标是使种群（尤其是优势种或建群种）到具有生长、繁殖和适应进化变化的能力。要达到这个目标,种群遗传学知识必不可少。遗传变异是物种适应变化环境的基础,而局部适应则是种群适应局部环境遗传分化的结果,它们在生态恢复中起着重要的作用。分析了生态恢复过程中影响种群遗传变异因素,主要有取样误差和小种群效应（主要是瓶颈或建立者事件及其以后的近交和漂变等）,在进行

大数据时代政府环境治理路径创新

本文针对政府环境治理面临政府失灵、市场失灵和社会低效三个困境,提出运用大数据方法创新治理路径。政府应用大数据提高环境治理过程中的事前、事中和事后监管效能,创新监管模式提升环境治理能力,改善政府失灵困境;依托大数据完善市场化调节机制,激励企业环境行为市场化,构建企业环境信用评价体系,改变企业环境信息披露模式,弥补市场失灵;利用大数据增进公众环境意识,建设公开、透明、平权化的环境信息交互体系,重视环境信息的舆情引导,促进环保价值理念传播,改变公众参与低效现状。进而提出完善大数据治理平台、技术和体系,构建政府、企业、公众共同参与的立体化环境治理模式,提高环境治理的精准化、精细化和智能化水平。     

区块链技术在安全生产信息化建设中的应用

为了促进安全生产信息化平台在数据方面进行分析以及整合,基于区块链本身的匿名性、去中心化、安全性、开放性以及独立性等优势,提出将区块链技术应用于安全生产信息化建设,研究表明,区块链技术的应用将能够为企业针对生产安全状态进行有效监督提供最大的帮助,最大限度的实现资源共享,为企业监督、政府部门监管提供便利条件,各企业之间就安全问题进行交流沟通,安全评价服务机构针对各企业安全生产存在的问题提供更有针对性的服务,同时对于提升服务效率以及服务质量有着重要现实意义。     

重构煤炭主体专业教育的公益性

从煤炭主体专业教育具有的公益性属性分析入手,指出煤炭主体专业的办学经费日紧和煤炭主体专业边缘化与去煤化,公益性日渐式微。建议从国家、高校、企业、个人家庭等各个层次全方位重构煤炭主体专业教育的公益性,加强国家利益至上,强化政府主渠道作用,在政策与教育投入要向其倾斜,优先发展与保障煤炭主体专业的教育,制定相关法规确保煤炭专业生源与人才培养质量,并在该领域就业。国家、企业、高校与个人家庭利益相关者都应在制度上强化各自应有的责任,从而形成一个多层次全方位良性互动发展的培养与吸纳人才的机制,确保煤炭主体专业教育的公益性,促进煤炭主体专业健康发展,满足安全生产的人才需求的供给,从而为煤炭安全生产提供重要保障。     

Cash transfers' effect on government support: the case of Fiji

While some scholars have found that government post-disaster assistance supports the incumbent, others have shown that incumbent effects among beneficiaries are imperceptible or negative. This article contributes to this debate by using a regression discontinuity design of households affected by Tropical Cyclone Winston in Fiji to show that the type of assistance provided is an important variable in understanding the effects of aid on perceptions of the government. Residents of Fiji who received a post-disaster cash transfer are up to 20 per cent more likely to be very satisfied with the government than are those who did not. The probability further increases if the cash transfer was provided along with in-kind benefits or vouchers, but it is not affected if beneficiaries were also encouraged to use their own pension savings. This paper provides evidence in favour of the ‘attentive citizen’ theory by demonstrating that beneficiaries actively appraise government responses; it also reveals possible effects of elite capture on the relationship between the government and beneficiaries.     

Regional economic disparities in Belgium and regional,national and supra‐national policies: an analysis of collective failure

Two kinds of regional disparities can be distinguished in Belgium. First there is the internationally well‐known dispute between Flanders and Wallonia. Secondly, there are large disparities within the regions. Three policy levels deal with these disparities: the (Flemish) regional level, the national government level and the EEC level. The purpose of this paper is to sketch the regional problems in Belgium, to analyse the policies that deal with them, to consider the co‐ordination problems between them and to shed some light on the public choice aspects of government interventions. It is concluded that regional policy in Belgium is a highly politicised affair. Furthermore public attention paid to regional policies has outgrown the importance of our regional disparities. Even other forms of micro‐economic policy are jeopardised by regional disparities and the resulting pressure.     

电子废弃物的再循环利用：企业、政府与公众的角色和责任

电子废弃物不仅种类繁多，而且成分复杂，含有多种有毒、有害物质，已成为固体废物中最大的重金属污染源。长期以来，由于对电子废弃物问题缺乏足够认识和有效管理，电子废弃物对人体健床及生活环境可能构成的危害常常被忽视。实现电子废弃物的再循环利用，关键是明确企业、政府和公众在电子产品设计、生产、消费、回收、处置和再利用整个过程中的相关责任。因此，解决电子废弃物的问题，首先要对相关行为主体的角色进行准确定位。
