The ethics of genetic engineering and gene drives in conservation

The ethical issues associated with using genetic engineering and gene drives in conservation are typically described as consisting of risk assessment and management, public engagement and acceptance, opportunity costs, risk and benefit distributions, and oversight. These are important, but the ethical concerns extend beyond them because the use of genetic engineering has the potential to significantly alter the practices, concepts, and value commitments of conservation. I sought to elucidate the broader set of ethical issues connected with a potential genetic engineering turn in conservation and provide an approach to ethical analysis of novel conservation technologies. The primary rationales offered in support of using genetic engineering and gene drives in conservation are efficiency and necessity for achieving conservation goals. The instrumentalist ethical perspective associated with these rationales involves assessing novel technologies as a means to accomplish desired ends. For powerful emerging technologies the instrumentalist perspective needs to be complemented by a form-of-life perspective frequently applied in the philosophy of technology. The form-of-life perspective involves considering how novel technologies restructure the activities into which they are introduced. When the form-of-life perspective is applied to creative genetic engineering in conservation, it brings into focus a set of ethical issues, such as those associated with power, meaning, relationships, and values, that are not captured by the instrumentalist perspective. It also illuminates why the use of gene drives in conservation is so ethically and philosophically interesting.     

Voluntary participation for sustainability transition: experiences from the ‘Commitment to Sustainable Development 2050’

Voluntary and active participation by a wide variety of actors is a prerequisite for successful societal transitions towards sustainability. The ‘Commitment to Sustainable Development 2050’ is a national-level initiative in Finland, aiming to mobilise a large-scale transition involving various societal actors through openly communicated commitments to concrete actions. Each commitment should focus on at least one of the eight nationally defined sustainability objectives connected to the global Sustainable Development Goals. This article assesses the implementation and the development needs of the commitment process based on a range of materials. The results highlight the importance of securing adequate resources for long-term coordination and continuous development of the commitment process, trust creation through long-term and open communication, and flexibility allowing for experimentation aimed at finding new modes of interaction between the public and private sectors.     

人因视角下建筑安全研究现状及发展趋势分析

为了提高建筑安全后续研究的有效性与针对性,从人因视角对其研究现状及发展趋势进行了系统总结。采用定性文献综述的方法从实践需求和理论发展2个维度对国内外人因相关文献资料进行梳理、研判,通过明确焦点领域、核心方向、关键关注点等途径以明晰建筑安全研究现状及发展趋势,确定发展瓶颈,据此介入寻求突破的可能。研究结果表明:建筑工人不安全行为心理研究不足是人因视角下制约建筑安全理论发展的瓶颈,也是提升建筑安全管理应对的关键着力点;同时,从认知过程新视角证实了基于认知神经学范畴的研究是突破上述瓶颈的关键方向,在此基础上结合神经测量技术ERP新工具论证了该论断的可行性,为后续研究提供借鉴。     

基于煤矿安全生产标准化的双控机制APP系统研究

针对我国煤矿安全生产标准化工作中数据采集的时效性差、数据录入工作量繁琐、数据汇总分析不明确的问题,利用易安卓编程语言与SQLite数据库技术,采用瀑布生命周期模型的软件开发方法,以《煤矿安全生产标准化考核定级办法》中双控机制的基本内容为依据,设计包括个人信息管理、法律知识库检索、安全风险分级管控、事故隐患排查治理、数据可视化分析、其他6大功能模块的APP系统。结果表明:该系统可提供适合相关管理人员使用的可视化界面,减少了复杂繁琐的工作量,为标准化工作的定点巡检与数据的完整性提供了良好的技术支持,也为非煤矿山、冶金、石油化工等行业的标准化工作实现信息化管理提供了较好的应用模式。

Structural change and sustainable development

In this paper, we show that the commonly observed decline in primary (natural resource using) sector output and employment shares, often termed structural change, can be explained as an endogenous response to the presence of nature's constraint. Structural change takes place even if consumer preferences are homothetic, and technological progress does not discriminate against the primary sector. Under certain conditions, structural change allows an open economy to grow with natural resource sustainability. Sustained and environmentally sustainable economic growth is possible even if the natural resource is exploited under open access. Well-defined property rights are neither necessary, nor sufficient for sustainable growth. We show that there is no unique relationship between natural resource endowment and the rate of economic growth over the long run. Resource-rich economies may grow faster or slower than resource-poor ones.
