Are the Precautionary Principle and the International Trade of Genetically Modified Organisms Reconcilable?

This paper seeks to find possibilities forreconciliation of the implementation of theprecautionary principle and the promotion ofinternational trade of genetically modified organisms,based on the assumption that a sustainabledevelopment is a right objective to strive for. Itstarts with an explanation of the background and therole of the precautionary principle, and describes inwhat way measures based on the precautionary principlecan easily lead to the creation of trade barriers. Thearticle then examines to what extent the WTO (WorldTrade Organisation) Agreements allow theimplementation of the precautionary principle. Inaddition, structural conflicts between the perceptionof the precautionary principle and the concept oftrade liberalisation will be evoked. The last sectionof the paper analyses to what extent the WTO rulesprovide possibilities to avoid or solve theseconflicts in order to attempt to answer the mainquestion: are the precautionary principle and theinternational trade of genetically modified organismsreconcilable?

Forest growth in the light of the thermodynamic theory of ecological systems

The observed growth of a particular forest stand can be described by many models and explained by some of them. The forest growth models are also successfully applied for extrapolating the growth curve. However, the known models of forest growth are not “one-point” models. They are not designed to predict the future growth of a forest stand from its current state: the model parameters either are not directly measurable or cannot be measured with relevant accuracy. This article is an attempt to use Jørgensen–Svirezhev theory as a new clue to the choice of variables that determines forest growth. The postulates of this theory combined with the pipe theory of tree growth lead to conclusion that biomass of a stand should be proportional to the four-fifths power of its age. Empirical validation, however, disclosed that calendar age is rather approximate measure of ecosystem ontogeny. Delayed development or intensive thinning of a forest stand at the early stages leads to rejuvenation bias. Thus derived 4/5-law model approximates well-known Chapman–Richards model in the neighborhood of the inflection point, and is applicable to middle-aged forest stands.

基于灰色GM(1,1)-马尔科夫模型的职业病预测研究

为准确预测量化我国职业病的发病趋势,在灰色GM(1,1)模型的基础上结合马尔科夫过程构建灰色GM(1,1)-马尔科夫预测模型,探讨灰色GM(1,1)-马尔科夫模型在职业病预测领域的应用。通过平均相对误差、后验差比值、小误差概率3个指标对该组合模型的预测精度进行评估。结果表明:10维灰色GM(1,1)-马尔科夫模型与原始数列的拟合程度较高,预测精度等级为一级（好）,该组合模型的预测精度优于单一的灰色GM(1,1)预测模型;在遵循新陈代谢原理的情况下,我国职业病发病呈现上升态势,2015—2018年的职业病发病例数依次为31 196,36 284,37 724,39 147例。     

基于主成分分析法的液体管道泄漏后果综合评价模型

基于主成分分析和后果评价模型,提出了一种液体管道泄漏后果综合评价方法。将液体管道泄漏后果划分为火灾、爆炸和中毒3大类14个基本指标,建立后果评价指标体系。在VCE等后果模拟计算的基础上得到初始数据,运用SPSS软件处理相关数据,使用主成分分析法得到各指标相互独立的综合评价模型。选择天津港某码头进行实例分析,运用该方法对该港口储运的15类有代表性液体危险化学品进行综合评价,得到了各化学品的综合评价值以及按照其发生泄漏后危险性大小的排序。结果表明,该方法适用于评价港口码头等储运多种液体危险化学品的行业。
