The Dutch people and the euro: A structural equations analysis relating national identity and economic expectations to attitude towards the euro

National identity, macro and micro economic expectations affect the attitude toward the euro. In a study in The Netherlands, data were collected and relationships between the latent concepts were modelled with LISREL. In the best fitting model, national identity has a direct and an indirect effect on attitude, respectively, an unstructured and a structured effect. The indirect effect is mediated by macro and micro expectations. Macro expectations also have a direct and an indirect effect. The indirect effect is mediated by micro expectations. On one hand, macro expectations form a strong link between national identity and attitude. On the other hand, macro expectations have a strong direct effect on attitudes. The euro is mainly perceived and evaluated in a macro-economic perspective.PsycINFO classification: 2229; 3920     

新课程改革之教学改革三步走

探讨了教学改革在新课程改革中的重要作用和意义,站在教师教学的立场上提出了新课程改革之教学改革三步走的设想。认为教学改革的第一步是教师包括教育教学人员的态度和理念的变化,其中包括他们对新课程计划的认同、采纳以及在教学过程中自觉地贯彻新课程理念,在忠实新课程理念的前提下最终成为实施新课程的主体;第二步是本着忠实新课程的文化和教育理念去实践新课程,从而使观念的课程计划转变为现实的教学行为;第三步是彻底实现从"传统教学"向"新教学"的转变,即实现新教学的永续。

Multivariate inverse Gaussian distribution as a limit of multivariate waiting time distributions

Multivariate inverse Gaussian distribution proposed by Minami [2003. A multivariate extension of inverse Gaussian distribution derived from inverse relationship. Commun. Statist. Theory Methods 32(12), 2285–2304] was derived through multivariate inverse relationship with multivariate Gaussian distributions and characterized as the distribution of the location at a certain stopping time of a multivariate Brownian motion. In this paper, we show that the multivariate inverse Gaussian distribution is also a limiting distribution of multivariate Lagrange distributions, which is a family of waiting time distributions, under certain conditions.     

Estimation of the number of studies with positive trends when studies with negative trends are present

A two-point estimator is proposed for the proportion of studies with positive trends among a collection of studies, some of which may demonstrate negative trends. The proposed estimator is the y-intercept of the secant line joining the points (a, F?(a)) and (b, F?(b)), where F?(p) is the empirical distribution function of p-values from one-tailed tests for positive trend derived from the individual studies. Although this estimator is negatively biased for any choice of the points 0 ≤ a < b ≤ 1, the bias is less than that of the previously proposed one-point estimator defined by setting b = 1. The bias of the two-point estimator is smallest when a and b approach the inflection point of the true distribution function, E [F?(p)]. The utility of the two-point estimator is demonstrated by using it to estimate the number of male-mouse liver carcinogens among carcinogenicity studies conducted by the National Toxicology Program.
