Training für ein Leben mit Vielfalt?

Training for a life in multiplicity. The competence of trainers in intercultural settings Training in intercultural skills is often requested in social and administrative organizations and institutions. Since up to now an education for intercultural trainers analogous to traditional training in psycho-social skills doesn’t exist, the author discusses the standards of quality which are generally applied in measuring the professional competence of psychosocial trainers and which standards should be applied to those offering intercultural trainings.     

Seeking useful contribution

This short communication is an attempt to define useful contribution in statistical consulting and to connect it to a collection of favorable attitudes and skills. It stresses the need for adequate education of beginning statisticians to render them capable of contributing effectively to society, business, and research. The communication ends with a list of related articles and publications.     

Monitoring correlated processes with binomial marginals

Few approaches for monitoring autocorrelated attribute data have been proposed in the literature. If the marginal process distribution is binomial, then the binomial AR(1) model as a realistic and well-interpretable process model may be adequate. Based on known and newly derived statistical properties of this model, we shall develop approaches to monitor a binomial AR(1) process, and investigate their performance in a simulation study. A case study demonstrates the applicability of the binomial AR(1) model and of the proposed control charts to problems from statistical process control.     

The susceptible circle: A taxonomy of followers associated with destructive leadership

While leadership scholars increasingly acknowledge the influence of followers in the leadership process, less attention has been paid to their role in the destructive leadership process. Specifically, the current debate lacks a broad-based understanding of different susceptible follower types that synthesizes related research across academic domains. Expanding on Padilla, Hogan, and Kaiser's (2007) toxic triangle model of destructive leadership, we integrate research and theory across various academic literatures to derive a cohesive taxonomy of vulnerable followers that we call the susceptible circle. We describe the core characteristics of each follower type, drawing on Barbuto's (2000) theory of follower compliance to highlight the psychological processes that motivate each follower to comply with destructive leaders. We then conclude by discussing theoretical and practical implications, as well as avenues for future research.     

On the Ghoudi,Khoudraji, and Rivest test for extreme‐value dependence

Ghoudi, Khoudraji & Rivest [The Canadian Journal of Statistics 1998;26:187–197] showed how to test whether the dependence structure of a pair of continuous random variables is characterized by an extreme‐value copula. The test is based on a U‐statistic whose finite‐ and large‐sample variance are determined by the present authors. They propose estimates of this variance which they compare to the jackknife estimate of Ghoudi, Khoudraji & Rivest ( 1998 ) through simulations. They study the finite‐sample and asymptotic power of the test under various alternatives. They illustrate their approach using financial and geological data.
