A note on Läuter-type robust design for polynomial regression models

In this paper, we consider the problem of model robust design for simultaneous parameter estimation among a class of polynomial regression models with degree up to k. A generalized D-optimality criterion, the Ψ_α‐optimality criterion, first introduced by Läuter (1974) is considered for this problem. By applying the theory of canonical moments and the technique of maximin principle, we derive a model robust optimal design in the sense of having highest minimum Ψ_α‐efficiency. Numerical comparison indicates that the proposed design has remarkable performance for parameter estimation in all of the considered rival models.     

A test statistic for weighted runs

A new test statistic based on runs of weighted deviations is introduced. Its use for observations sampled from independent normal distributions is worked out in detail. It supplements the classic χ² test which ignores the ordering of observations and provides additional sensitivity to local deviations from expectations. The exact distribution of the statistic in the non-parametric case is derived and an algorithm to compute p-values is presented. The computational complexity of the algorithm is derived employing a novel identity for integer partitions.     

Strong Consistency of Conditional Value-at-risk Estimate for ϕ-mixing Samples

In this article, we investigate the strong consistency of conditional value-at-risk estimate for ? ?mixing samples under mild conditions. Moreover, the corresponding strong consistency rate is also obtained.     

Standardisierungspotentiale lebenszyklusbasierter Modelle des strategischen Kostenmanagements

Tremendous increases in indirect costs can be found in many industries. Consequently, life cycle cost analysis models are getting more important in strategic cost management. However, existing models differ significantly from each other as they have been developed mainly for specific applications. In order to enable a common use of those models, a standardization of these models is required. We examine the potentials of standardizing models for life cycle cost analysis. In a first step, requirements regarding a standard model are derived from literature. As a second step, existing approaches found in literature are compared to the afore derived demands and it is analyzed to what extent they match the standardization requirements. Based on this comparison, we identify and discuss avenues for further research.     

Abschlussprüferhaftung bei unpräzisen Sorgfaltsstandards und Ambiguitätsaversion

The Ellsberg-paradox suggests that individuals are subject to ambiguity aversion. When the standard of due care is not precisely defined, the context of auditor’s liability can be considered as an ambiguity situation. The paper shows that compared to an Expected Utility framework an ambiguity-averse auditor will exert less care with low damage payments but higher care with high damage payments. Hence, it might be advisable to put a liability cap. With strict liability there is no ambiguity situation and thus, there are no distortions from ambiguity aversion.     

The empirical analysis of the -bilateral optimized combinatorial auction model

This study proposes a new and highly efficient dynamic combinatorial auction mechanism—the N-bilateral optimized combinatorial auction (N-BOCA). N-BOCA is a flexible iterative combinatorial auction model that offers more optimized trading for multiple suppliers and purchasers in the supply chain than one-sided combinatorial auction. We design the N-BOCA model from the perspectives of market architecture, trading rules, and decision strategy for winner determination, the decision strategy for winner determination needs flexible optimization modeling capability. Thus rule-based reasoning was applied for reflecting the flexible decision strategies. We also show the viability of N-BOCA through Paired Samples T-test experimentation. It shows that N-BOCA yields higher purchase efficiency and effectiveness than the one-auctioneer to multi-bidders (1-to-N) combinatorial auction mechanism.

Das 360-Grad-Feedback zur Unterstützung der Kompetenzerweiterung von Führungskräften

Zusammenfassung:  Der Beitrag beschreibt die Einbettung des 360-Grad-Feedbacks in ein Programm der Führungskr?fteentwicklung. 360-Grad-Feedback ist eine Voraussetzung für die systematische Kompetenzentwicklung der Führungskr?fte eines Unternehmens. Darüber hinaus k?nnen die Entwicklungs- und Lernm?glichkeiten, die ein individuelles Coaching bietet, durch ein vorheriges 360-Grad-Feedback optimiert werden. Die bei ThyssenKrupp Services mit dem F?rderprogramm „best-for-best“ gesammelten Erfahrungen zeigen deutlich, dass die Kombination von einem 360-Grad-Feedback mit gezielten Coaching-Angeboten ein echtes Erfolgsmodell darstellt.

略论软实力发展视阈下的区域形象塑造

区域形象是一种无形资产和战略资源,是区域“软实力”的重要组成部分。塑造良好的区域形象有利于促进区域经济发展,有利于加强区域对外交流与合作,有利于区域内其它资源优势的发挥,有利于优化区域社会环境,提高区域社会整体文明程度和区域综合竞争力。因此,塑造良好的区域形象,直接关系到区域的长远发展。在区域现代化建设过程中,必须高度重视区域良好形象的塑造,要以区域综合实力的不断发展,为区域形象塑造提供有力支撑,要有一个系统的塑造区域形象的实施战略,同时要重视不断提升区域公众的文明素质和形象意识。
