Can food safety policy-making be both scientifically and democratically legitimated? If so,how?

This paper provides an analysis of the evolution of thinking and talking about the role of scientific knowledge and expertise in food safety policy-making, and in risk policy-making more generally from the late 19th century to the present day. It highlights the defining characteristics of several models that have been used to represent and interpret the relations between policy-makers and expert scientific advisors and between scientific and political considerations. Both conceptual and empirical strengths and weaknesses of those models are identified, focusing in particular on the ways in which they deal with scientific uncertainties and social choices. By drawing on both empirical evidence and conceptual analysis, a novel and more realistic model is provided along with an account of some conditions for food safety policy-making achieving both scientific and democratic legitimacy.     

从安全科学的本质看安全专业教育的发展趋势

笔者从安全科学的本质分析入手,剖析安全专业教育的公共性、伦理性、综合性、复合性、实践性等本质属性,指出当前我国安全专业教育存在的问题,如公共性的缺失、忽视安全伦理教育、本质安全人的失落、实践能力的降低、通识教育的滑坡等等。并提出我国安全专业教育的发展趋势:走向公共性的复位;安全本质人的重塑;在课程开设中增加安全哲学、安全教育学、安全文化学等人学课程;重视学生工程实践能力的培养,向工程实践的回归;强调学生的综合素养教育,使其加大职业的适应度,走向通识教育的归位;重视伦理道德教育,将增设工程伦理与安全伦理学课程,并在每门课程的实际教学层面融入伦理方面的教育。     

安全科学学的初步研究

从安全科学学的高度,论述安全学科的属性为综合属性,并认为开展安全科学学的研究,才能获得更加重要、更具原创性和更加系统性的理论研究成果。笔者从发展安全学科的角度出发,给出了安全科学学、安全科学方法学、安全科学学公理、比较安全学的基本定义和内涵;从安全学科的属性总结出5条安全科学学公理;指出安全科学学的研究,可以以安全科学方法学的研究作为突破口,安全科学方法学的研究可以以比较安全学作为切入点;还从多个角度对安全科学方法学进行了分类;指出现在安全科学基础研究非常薄弱,安全学科的发展需要更多的研究者投入到安全科学的研究领域中。笔者的论文是第一篇比较系统开展安全科学学研究的论文,对安全学科的发展具有理论指导作用。     

安全管理学及其具体教学内容的构建

通过对安全管理实务和安全管理活动的理论分析,首先,把安全管理学广义地定义为关于事故预防的科学,并分析得到其详细内容、逻辑结构和应用原理;然后,将安全管理学狭义地定义为与安全相关的关于行为协调的科学,并选择性地构建其具体的、与其他课程没有或较少交叉的具体教学内容。     

Comparison of Four Machine Learning Methods for Predicting PM10 Concentrations in Helsinki, Finland

Machine learning methods can offer a practicalalternative to deterministic and statistical methods forpredicting air pollution concentrations. However, for agiven data set, it is often not clear beforehand whichmachine learning method will yield the best predictionperformance. This study compares the variable selection andprediction performance of four machine-learning methods ofdifferent complexity: logistic regression, decision tree,multivariate adaptive regression splines and neuralnetwork. The methods are applied to the task of predictingthe exceedance of the European PM₁₀ daily averageobjective of 50 g m^-3 for a station in Helsinki,Finland. Our study shows that some predictors were selectedby all models but that the different models also pickeddifferent variables. The performance of three of the fourmethods investigated was very similar, however, performanceof the decision tree method was significantly inferior.Performance was sensitive to the learning sample size andtime period used.
