社区防灾减灾对策的复杂性科学问题

"社区研究"已有约150年的历史,社区的防灾减灾对策是一个综合性的科学问题。充分发挥社区的防灾减灾功能十分必要,确立社区防灾减灾最优对策在中国的现代化建设和可持续发展战略中具有重要意义。利用复杂性科学的理论和模型来处理社区的防灾减灾对策问题,是系统科学或复杂性科学中的一个有意义的发展方向。本文提出并分析了社区防灾减灾对策研究中的4个问题,即如何界定社区防灾减灾应急管理的角色和方向;何为防灾减灾安全社区;如何预警突发性灾难事件;社区防灾减灾系统是如何自组织的。本文引入复杂性科学理论对社区的防灾减灾对策进行了研究,讨论了复杂性科学应用于社区防灾减灾对策的理论框架。

黄渤海气溶胶光学厚度的多源卫星遥感产品精度分析和时空分布特征研究

以黄渤海上空大气为目标研究区,基于AERONET观测网,获取该区域2015—2017年的气溶胶光学厚度(AOD)实测数据,并对可见红外成像辐射计VIIRS,中分辨率成像光谱仪MODIS,静止水色卫星成像仪GOCI与新一代地球同步气象卫星AHI H8的AOD遥感产品展开精度验证.同时,利用长时间的遥感影像探究并分析AOD在不同时空尺度下的分布特征与变化情况.结果表明:同其它AOD遥感产品相比,GOCI AOD展示出了高采样频率及高精度的特性.此外,在研究区域AOD的逐小时遥感影像中未发现明显的变化规律,而月平均图则显示出从黄渤海西部至中部再到东部AOD逐渐递减的趋势,且该趋势在研究区域不同的地方是具有差异的.不仅如此,本文还尝试分析影响AOD反演精度的潜在因子,发现其可能与地表反射率提取的准确度与预设气溶胶模型设置的合理性有关.     

Ethical considerations when conservation research involves people

Social science is becoming increasingly important in conservation, with more studies involving methodologies that collect data from and about people. Conservation science is a normative and applied discipline designed to support and inform management and practice. Poor research practice risks harming participants and, researchers, and can leave negative legacies. Often, those at the forefront of field-based research are early-career researchers, many of whom enter their first research experience ill-prepared for the ethical conundrums they may face. We draw on our own experiences as early-career researchers to illuminate how ethical challenges arise during conservation research that involves human participants. Specifically, we considered ethical review procedures, conflicts of values, and power relations, and devised broad recommendations on how to navigate ethical challenges when they arise during research. In particular, we recommend researchers apply reflexivity (i.e., thinking that allows researchers to recognize the effect researchers have on the research) to help navigate ethical challenges and encourage greater engagement with ethical review processes and the development of ethical guidelines for conservation research that involves human participants. Such guidelines must be accompanied by the integration of rigorous ethical training into conservation education. We believe our experiences are not uncommon and can be avoided and hope to spark discussion to contribute to a more socially just conservation.     

Occupational injury rates among Norwegian farmers: A sociotechnical perspective

Introduction: This study addressed relative injury risk among Norwegian farmers, who are mostly self-employed and run small farm enterprises. The aim was to explore the relative importance of individual, enterprise, and work environment risks for occupational injury and to discuss the latent conditions for injuries using sociotechnical system theory. Method: Injury report and risk factors were collected through a survey among Norwegian farm owners in November 2012. The response rate was 40% (n = 2,967). Annual work hours were used to calculate injury rates within groups. Poisson regression using the log of hours worked as the offset variable allowed for the modeling of adjusted rate ratios for variables predictive of injury risk. Finally, safety climate measures were introduced to assess potential moderating effects on risk. Results: Results showed that the most important risk factors for injuries were the design of the workplace, type of production, and off-farm work hours. The main results remained unchanged when adding safety climate measures, but the measures moderated the injury risk for categories of predominant production and increased the risk for farmers working with family members and/or employees. An overall finding is how the risk factors were interrelated. Conclusions: The study identified large structural diversities within and between groups of farmers. The study drew attention to operating conditions rather than individual characteristics. The farmer’s role (managerial responsibility) versus regulation and safety climate is important for discussions of injury risk. Practical Applications: We need to study sub-groups to understand how regulation and structural changes affect work conditions and management within different work systems, conditioned by production. It is important to encourage actors in the political-economic system to become involved in issues that were found to affect the safety of farmers.     

Development of inherent safety and health index for formulated product design

The numerous formulated products which are introduced to the market consist of chemical ingredients that may cause various safety and health hazards to the consumers. Therefore, it is extremely important to practice a systematic methodology to formulate products with acceptable safety and health performances. This work presents an index-based methodology to assess the safety and health hazards of the ingredients during the early formulation stage of product design. Hence, new inherent safety and health sub-indexes are introduced to improve the current safety and health hazards that are needed in formulated product design. The inherent safety and health sub-indexes are assigned with scores based on the degree of potential hazards. A higher score indicates a higher safety risk or severe health effect, and vice versa. The proposed methodology will greatly assist the users to identify the adverse safety and health effects caused by the ingredients. Hence, it is pivotal to eliminate or reduce the safety and health impacts from product usage. A case study on common ingredients used in the formulation of paint is presented on this study to describe the proposed method.
