Consensual commitment: A grounded theory of the meso-level influence of organizational design on leadership and decision-making

This research examined the relationship between organizational design and leadership in decision-making teams. It used a grounded theory-based qualitative research design. The validity of the research was enhanced by data triangulation, wherein quantitative psychometric data augmented the qualitative data that are traditionally used. The research was based upon two organizations within the substantive setting of the knowledge industry. The higher order category of consensual commitment explained effective decision-making. At the meso-level of leadership modeling, organizational design influenced both leadership style and decision-making. Specifically, an organizational design that generated lateral job roles and a relational leadership orientation was found to enhance consensual commitment, and provided a level of assurance against dysfunctional team dynamics.

Qualitative research on leadership: A critical but appreciative review

This article reviews a large number of articles that derive from qualitative research on leadership that were published prior to 2004 in peer-reviewed journals. The article then goes on to examine critically but appreciatively the ways in which qualitative research on leadership is and is not distinctive. This review shows that while qualitative research has made some important contributions to certain areas of leadership, such as the role of leaders in the change process, it is sometimes not as distinctive, when compared to quantitative research, as might be supposed. The piece also examines studies that combine quantitative with qualitative research. The different ways in which the two approaches are combined is a particular emphasis in this examination. In addition, the article explores the issue of whether the corpus of research that has been accumulated by qualitative researchers can be combined with that of quantitative researchers. A central ingredient of the discussion of qualitative research is the tendency for many researchers not to build sufficiently on the studies of leadership conducted by others. It is argued that giving greater attention to this issue will allow the contributions of qualitative research on leadership to become clearer.     

组合拍卖与议价谈判机制设计研究

设计了一种先组合拍卖再议价谈判的多物品出售两阶段机制.论文分析表明,机制的组合拍卖阶段保持了VCG机制的激励相容性质,在机制的议价谈判阶段,存在4种不同类别的获胜投标者,就拍卖者将采取的不同价格策略,可将其区分为第1类投标者和第2类投标者.据此,找到了拍卖者采取不同价格策略的相应条件.给出了该机制中拍卖者与任意获胜投标者之间的博弈均衡路径.就买卖双方的总估价而言,存在不同相对关系下的不同交易结果.对比该机制和经典VCG机制,该机制改进社会交易福利值为:第1类投标者在议价价格和VCG价格下带给拍卖者利润的变化值.此结果表明,该机制的社会交易福利优于经典VCG机制.     

e-SCM系统的收益测算机制设计

作为供应链管理(Supply Chain Management,SCM)的支持手段,e-SCM系统(electronic Supply Chain Management System)的投资滞后成为制约SCM实现的重要障碍。本文借助Preinreich-Luecke定理、相对直接成本以及作业成本法所提供的理论框架,设计了简便易行的e-SCM系统收益测算机制,将其作为e-SCM系统投资决策的先导和收益实现的重要基础。本文的主要结论是:仅当业绩量的成本来源具有可变特质时,e-SCM系统所带来的业绩量才会产生经济收益,以库存为核心的资金占用成本因而成为业绩额的主要来源。仅需提取企业少量运营数据即可进行e化收益测算,客观上增加了测算的可行性。     

A Flexible Evaluative Framework for Order Picking Systems

This paper develops a novel framework to evaluate the integral performance of order picking systems with different combinations of storage and order picking policies. The warehousing literature on order picking mostly considers minimizing either elapsed time or distance as the sole objective, whereas warehouse managers in a supply chain have to look beyond single‐dimensional performance and consider trade‐offs among different criteria. Thus managers still need a unified and efficient framework to select a portfolio of appropriate order picking policies from a multi‐criteria and contextual perspective. Our framework—combining data envelopment analysis, ranking and selection, and multiple comparisons—provides an efficient methodology to simultaneously analyze several interrelated problems in order picking systems with multiple performance attributes, such as service levels and operational costs. We demonstrate our approach through comprehensive evaluations of order picking policies in three low‐level, picker‐to‐parts rectangular warehouses facing demand variations.     

The Dynamic Pivot Mechanism

We consider truthful implementation of the socially efficient allocation in an independent private‐value environment in which agents receive private information over time. We propose a suitable generalization of the pivot mechanism, based on the marginal contribution of each agent. In the dynamic pivot mechanism, the ex post incentive and ex post participation constraints are satisfied for all agents after all histories. In an environment with diverse preferences it is the unique mechanism satisfying ex post incentive, ex post participation, and efficient exit conditions. We develop the dynamic pivot mechanism in detail for a repeated auction of a single object in which each bidder learns over time her true valuation of the object. The dynamic pivot mechanism here is equivalent to a modified second price auction.     

存在荣誉效用的等级竞赛机制分析

针对存在荣誉效用的等级竞赛,研究在等级数已定的条件下,以总努力最大化为目标的竞赛设计者如何设置竞赛人数和各等级人数的问题。通过分析荣誉效用由于相邻等级容量调整所引起的变化对总努力的影响,得到结论：无论能力分布如何,将最高等级容量设置得很小,对竞赛设计者而言,是更合理的选择;当竞赛者的能力分布为凹函数时,将中低等级的容量设置得相对较大更合理;当能力分布为凸函数时,将中高等级的容量设置得相对较小更合理。
