What Determines Trust in Information About Food-Related Risks? Underlying Psychological Constructs

Trust in risk information about food related-hazards may be an important determinant of public reactions to risk information. One of the central questions addressed by the risk communication literature is why some individuals and organizations are trusted as sources of risk information and others are not. Industry and government often lack public trust, whereas other sources (for example, consumer organizations, the quality media, medical doctors) are highly trusted. Problematically, previous surveys and questionnaire studies have utilized questions generated by the investigators themselves to assess public perceptions of trust in different sources. Furthermore, no account of the hazard domain was made. In the first study reported here, semistructured interviewing was used to elicit underpinning constructs determining trust and distrust in different sources providing food-related risk information ( n = 35). In the second study, the repertory grid method was used to elicit the terminology that respondents use to distinguish between different potential food-related information sources ( n = 35), the data being submitted to generalised Procrustes analysis. The results of the two studies were combined and validated in survey research ( n = 888) where factor analysis indicated that knowledge in itself does not lead to trust, but that trusted sources are seen to be characterised by multiple positive attributes. Contrary to previous research, complete freedom does not lead to trust—rather sources which possess moderate accountability are seen to be the most trusted.     

诉说离乱与建构主体——论马来西亚华人新生代的创作

马来西亚华人新生代的崛起是20世纪90年代以来马来西亚乃至东南亚华文文坛的重要现象.马来西来华人新生代在创作中甚为繁复地诉说着离乱的过往与身世的漂泊,这不但反映了他们成长期所经受的国族认同危机,而且透露出他们试图通过离乱历史的叙事而建构其马来西亚"国境内少数民族形象"的族群意识.但这种建构虽然以寻求认同为旨归,却天然地和当局打造马来西亚国族共同体的意识形态相冲突,而这冲突的双方在当前全球化语境中似乎又共同面临本真性幻觉的困境.

A generating algorithm for linear trend-free and nearly linear trend-free block designs

The theory and properties of trend-free (TF) and nearly trend-free (NTF) block designs are wel1 developed. Applications have been hampered because a methodology for design construction has not been available.

This article begins with a short review of concepts and properties of TF and NTF block designs. The major contribution is provision of an algorithm for the construction of linear and nearly linear TF block designs. The algorithm is incorporated in a computer program in FORTRAN 77 provided in an appendix for the IBM PC or compatible microcomputer, a program adaptable also to other computers. Three sets of block designs generated by the program are given as examples.

A numerical example of analysis of a linear trend-free balanced incomplete block design is provided.

论陈抟易学思想的影响

陈抟所开启的宋代象数易学一方面以《周易》的卦爻象数为基础,另一方面又超出卦爻象数之外,创新性地融合易老之说,积极探索自然万物的化生奥秘。陈抟易道相通、太极是一的宇宙本体论,融合了道家本体论和儒家太极说,并与道教内丹学紧密结合。同时,这种宇宙生成模式对邵雍、刘牧、周敦颐等宋儒以思维性启迪和深刻影响。

平面波照明正交光栅时的Talbot效应

本文根据菲涅尔衍射理论,讨论了平面波照明时,两方向周期d_x≠d_y的正交光栅的Talbot效应。指出,两方向周期满足k_x/k_y=(d_y~2)/(d_x~2)的关系时,才能得到完整信息的Talbot像。并据此,引入了混合Talbot像的新概念。给出了一种较Szwaykowski的方法优越的产生正交光栅的方法。并扩展了Szwaykowski的理论。实验结果和理论吻合很好。
