Consumer Selection of Food-Safety Information Sources

The aim of this study is to examine the preferences of consumers for different information sources when they have a question about food safety. On the basis of a nationally representative survey conducted in the Netherlands, five distinct consumer groups are identified that not only differ on the reported use of information sources but also regarding several personality characteristics and sociodemographic variables. The empirical results show that two-thirds of the consumers are selective in their use of information sources and prefer either institutional or social sources. So, multiple information-acquisition patterns exist among the general public. The study illustrates how these findings can help to develop effective risk communication strategies.     

具体人性——人权与宽容的新维度

简要列出宽容概念的种类,并概述人权与实际(或具体)人性之间的关联以及实质性的相互关系,基于针对人权的进一步区别、历史修正以及人权阐释的发展的评论,勾勒出人权从保护性人权向供人分享和有积极创造性的人权的发展历程,并提出与标准的法定人权相比,供人分享和有积极创造性的人权是对伦理上的真正尊严的主张,是一种道德人的准权利。因此,用“具体人性”和对具体人性的实际描述真正代替仅仅沉湎于人性和人道的相当抽象的观念,这在所有的人权教育中都是最重要的。     

论1807年的现象学的逻辑

在研究黑格尔《精神现象学》的内容时,应该同时研究其体系学的形式。1807年的现象学是建立在诸逻辑基本环节的某种序列的基础上的,而这种序列与黑格尔当时的逻辑学构想是相一致的,并且在现象学内具有一种统一的功能。要弄清这些基本规定之进程,有着诸多困难。在现象学的布局中的修改并没有走到损害现象学之逻辑根基的地步。本文第一章表明,从一开始,黑格尔就提出了这一要求:在非实在的意识的方式与逻辑的环节之间要有一种严格的对应。第二章讨论这些逻辑的环节作为什么进入意识的经验当中,以及它们如何组织意识的经验。第三章具体说明这些逻辑的基本环节的序列及其同意识的诸阶段的对应。文章最后还把一种有关现象学的方法和有关耶拿逻辑学的发展的见解,提出来进行了讨论。     

Pitfalls in multi-national long-range planning

The authors of this article argue that too many companies are not getting the benefits which should be produced by their long-range planning systems. Of the many possible explanations for this, the authors concentrate on the major pitfalls which should be avoided in order to ensure good results. The article is based upon the results of a survey of planning pitfalls among corporations in six industrialized countries.     

论科学与工程的结构性差异

工程最初被理解为自然科学的应用,然而科学与工程之间的区别是需要进一步澄清的。二者间最简单的区别表现在自然物的科学同人造物的科学之间的区别,而创造性并不能作为科学同工程之间的根本区别。工程师寻找实现目标的手段,手段则是由规则给出的,而且是在技术可能性上有效的。为了更好地理解工程,需要引入技术解释学,并且把工程科学的哲学溶入技术的形而上学之中。     

On the Effect of Risk Aversion in Bimatrix Games

Nash equilibria with identical supports are compared for bimatrix games that are different with respect to the risk aversion of player 2. For equilibria in 2× 2-bimatrix games and for equilibria with efficient supports in coordination games it is established for which cases increased risk aversion of player 2 benefits or hurts player 2.     

The implications of the Lima target: Explorations with a world industrialization model

The Second General Conference of the UNIDO held in Lima in 1975 declared that the share of developing countries in total world industrial production should reach 25% by the year 2000. The model presented in this article has been constructed in order to investigate whether this target is consistent with other more generally accepted goals of development and is feasible within the area of production and trade possibilities.The model is a dynamic, multisectoral, multiregional input-output model. It focuses on the impacts and mutual consistency of targets of growth, regional income distribution, industrialization, consumption levels, and trade. In the empirical application three periods, three regions, and nine sectors have been distinguished to produce intersectorally, interregionally, and intertemporally consistent accounts for the main variables. Since the study is concerned with the maximum possible growth of industrial output of the developing countries, a linear programming approach has been used.The report is organized as follows. After an introduction, the second section describes the mathematical model. The third section contains a detailed explanation of the data basis and of the assumptions made to stimulate the model. The numerical results of the model are discussed in the fourth section, and the main conclusions are given in the fifth.     

Decision problems under uncertainty based on entropy functionals

This essay intends to define the role of entropy, in particular, the role of the maximum entropy criterion with respect to decision analysis and information economics. By considering the average opportunity loss interpretation, the basic hypothesis for Shannon's derivation can be derived from properties of decision problems. Using the representation Bayes Boundary it is possible to show that selecting a single probability from a set by the Maximum Entropy Criterion corresponds to a minimax criterion for decision-making. Since problems of randomly accessing and storing information as well as communicating information can often be stated in terms of coding problems, this result might be used to develop strategies for minimizing retrieval time or communication costs.
