On perfect simulation for some mixtures of distributions

This paper studies the implementation of the coupling from the past (CFTP) method of Propp and Wilson (1996) in the set-up of two and three component mixtures with known components and unknown weights. We show that monotonicity structures can be exhibited in both cases, but that CFTP can still be costly for three component mixtures. We conclude with a simulation experiment exhibiting an almost perfect sampling scheme where we only consider a subset of the exhaustive set of starting values.

Die Einstellung zur Einführung des „Doppelpasses“

In this study the attitude towards the new nationality law in Germany is explained by a value/expectancy theory of attitude. 215 standardized face-to-face-interviews were performed with a quota sample. The results of this survey show that the value and expectancy theory of attitude is extremely successful in explaining the attitude towards the new nationality law. Models explaining the predictor variable of the attitude theory and a feedback-model were tested.     

Ability, individual development and optimal selection decisions

The paper analyzes different selection policies in education and business. We show that incorrect self-perceptions combined with imperfect performance measurement may cause significant welfare losses in selective educational systems, in particular if selection starts too early. Of course, these welfare losses can be mitigated by an investment in better ability assessment. However, an affirmative action policy could serve the same purpose as such an investment. We apply our analysis also to diversity management in firms. Based on positive discrimination we establish an efficiency argument for diversity management.     

超越自我 追寻精神——摭谈超个人心理学及其对教育的启示

超个人心理学在人本主义心理学的基础上进一步涵括了人的高层意识,认为人的本性是精神的,意识是多维的和发展的,道德是集体——内在的和整体的。这些观点有先进性也有不足,通过辨析,去其糟粕,取其精华,为我所用。这一理论启迪和警示教育：应唤醒人的精神意识、关注人的精神成长、提升人的精神境界。

The impact of acquisitions on firm performance: A review of the evidence

This paper presents a review of empirical research on the impact of acquisitions on firm performance. The evidence suggests that, in the short run, acquisitions have at best an insignificant impact on shareholder wealth. Long‐run performance analysis reveals overwhelmingly negative returns, while the evidence using accounting performance measures is mixed. The review also examines the impact of bid characteristics on performance. The acquisition of hostile targets, transactions that are paid for with cash and acquisitions of larger targets are associated with superior (or at least less negative) performance, while there is mixed evidence on the benefits of related acquisitions. A number of recent studies find that acquirers with superior pre‐bid performance tend to experience significant underperformance in the post‐bid period.
