Information technology — a challenge for the sparsely populated areas

The computer and telecommunications technology has created new opportunities for developing interaction between offices and enterprises located far away from each other. Even if the market forces favour concentration to R & D centres in the big cities and in university towns, there are expectations that the distance over‐bridging qualities of the new technology can create development opportunities for sparsely populated peripheral areas. In this paper the interplay between the new technology and other important factors in the local and regional environment are discussed with the focus on both opportunities and restrictions.

固定污染源烟气比对监测的几点思考

固定源烟气对比监测是保证自动监测数据质量的重要手段。但是,有效性审核比对监测过程中存在烟气排放连续监测系统安装不规范、手工监测抗干扰能力较差、烟气预处理效果不稳定及监测点位差异影响监测结果比对等问题。在此基础上,提出了严格规范环境监测点位的布置,针对不同的污染源确定适合的监测技术方法,研发完善的烟气预处理设施以及建立健全的自动监测质量保证体系等解决问题的对策。     

On the critique of Beck’s view on risk and risk analysis

Ulrich Beck’s stand on risk and risk analysis has been challenged by many researchers. In this paper we look closer into some of the arguments used, with a main focus on the fundamental analysis carried out by Campbell and Currie. These two authors argue that Beck’s criticisms of the theory and practice of risk analysis are groundless: Beck’s understanding of what risk is, is badly flawed, and he misunderstands and distorts the use of probability in risk analysis. However, the analysis of Campbell and Currie is based on a set of premises, for example that risk is a function of probability and harm, and that risk really exists and one can be wrong about risk. Although such ideas are common, they can be challenged, and in the literature a number of alternative perspectives have been suggested. The purpose of the present paper is to study Beck’s stand on risk analysis and the related critique of Campbell and Currie and others, in view of some of these alternative perspectives on risk. To what extent is the critique then justified? The paper concludes that the case raised against Beck’s view is still strong and relevant, but has to be nuanced with respect to some important issues, for example concerning the distinction between belief and truth when it comes to risk. Allowing for spacious interpretations of some of Beck’s theses, the paper provides strengthened support for Beck’s view on these points.     

工程项目现场安全标志有效性评价

为改善工程项目现场作业安全状况,需要对安全标志的有效性进行评价。通过划分施工人员的认知行为阶段,从人机工程学系统优化的角度构建安全标志有效性评价指标体系,确立指标打分规则,采用网络层次分析法(ANP),运用超级决策(SD)软件确定指标权重、综合评分,并加以示例说明。结果表明:安全标志的有效性受注意阶段的显著性、识别阶段的可理解性、判断阶段的安全倾向性和行为阶段的易遵守性交互影响,其中,安全倾向性权重值最高。     

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.

Expert system application for prioritizing preventive actions for shift work: shift expert

Introduction. Shift patterns, work hours, work arrangements and worker motivations have increasingly become key factors for job performance. The main objective of this article is to design an expert system that identifies the negative effects of shift work and prioritizes mitigation efforts according to their importance in preventing these negative effects. The proposed expert system will be referred to as the shift expert. Methods. A thorough literature review is conducted to determine the effects of shift work on workers. Our work indicates that shift work is linked to demographic variables, sleepiness and fatigue, health and well-being, and social and domestic conditions. These parameters constitute the sections of a questionnaire designed to focus on 26 important issues related to shift work. The shift expert is then constructed to provide prevention advice at the individual and organizational levels, and it prioritizes this advice using a fuzzy analytic hierarchy process model, which considers comparison matrices provided by users during the prioritization process. An empirical study of 61 workers working on three rotating shifts is performed. After administering the questionnaires, the collected data are analyzed statistically, and then the shift expert produces individual and organizational recommendations for these workers.
