Biologically Motivated Cancer Risk Models

A two-stage dose response model is proposed for use in cancer risk assessment. The model assumes that transformation probabilities and cellular dynamics are exposure- and time-dependent.     

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.

论通谋虚伪意思表示——从虚构房屋交易贷款案件说起

虚构房屋交易贷款案件涉及合同的效力在实践中争议较大，主要原因是未认识到该案件的性质属于通谋虚伪的意思表示，通谋虚伪意思表示在当事人之间无效，但不能对抗善意第三人。通谋虚伪意思表示在我国现行法中没有明确的规范，未来制定民法典时应明确虚伪意思表示在当事人之间的效力、针对善意第三人的效力，并对隐藏行为进行规范，特别应强调虚伪意思表示的当事人不得获益的原则。

作为师生沟通媒介的手机及其引发的新课题——以南京大学本科师生为例

人际传播媒介演进总是带来人际沟通领域的深刻变化。手机和手机短信作为当今高校辅导员与学生沟通的主要方式之一,不仅提高了师生沟通的效率,也改变了双方的沟通形态。文章以南京大学本科师生为调查对象,结合问卷调查法和观察法,探讨手机普及给师生沟通带来的变化。     

H_2O_2对大豆根边缘细胞发育的影响

以大豆根发育不同阶段的边缘细胞为对象,研究不同浓度H2O2对其活性的影响.结果表明:大豆根边缘细胞游离发育的启动与初生根发育几乎同步,并且在初生根生长至15mm时,边缘细胞数目达到最大值,约为5100个;低浓度H2O2对边缘细胞的活性具有促进作用,高浓度则抑制其活性.     

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。
