This article looks at the history of business schools and identifies specific characteristics that are common to European management schools. On the basis of these characteristics, European management is subsequently defined as a cross-cultural, societal management approach based on interdisciplinary principles. In a final step, a closer look is taken at how European business schools should prepare their students for the unique European management context. It is suggested that such schools should provide courses on cross-cultural management and courses explaining the interdependencies between the private and public sector, offer students opportunities to experience other cultures over the course of their studies, and teach management from an interdisciplinary and practically-oriented perspective.  相似文献

This paper studies the sensitivity of long-run trends in top income shares to differences in top-share measures. While the standard measure fixes a share of the population, we define alternatives that allow variation in both incomes and size of the top group based on defining absolute income thresholds. In an application to United States data, we find that top income share trends over the past century vary somewhat depending on the measure used. Allowing top groups to increase in size after 1980 along with overall economic growth results in a larger increase of top income shares. The historical drops before WWII are sensitive to the choice of income deflator: using GDP inflates interwar top income shares but using CPI deflates them. Altogether, these results recommend using complementary approaches to defining top income groups when measuring long-term top income share trends.

This paper quantifies the extent to which infants can perceive audio–visual congruence for speech information and assesses whether this ability changes with native language exposure over time. A hierarchical Bayesian robust regression model of 92 separate effect sizes extracted from 24 studies indicates a moderate effect size in a positive direction (0.35, CI [0.21: 0.50]). This result suggests that infants possess a robust ability to detect audio–visual congruence for speech. Moderator analyses, moreover, suggest that infants’ audio–visual matching ability for speech emerges at an early point in the process of language acquisition and remains stable for both native and non-native speech throughout early development. A sensitivity analysis of the meta-analytic data, however, indicates that a moderate publication bias for significant results could shift the lower credible interval to include null effects. Based on these findings, we outline recommendations for new lines of enquiry and suggest ways to improve the replicability of results in future investigations.  相似文献

The approximate Bayesian computation (ABC) algorithm is used to estimate parameters from complicated phenomena, where likelihood is intractable. Here, we report the development of an algorithm to choose the tolerance level for ABC. We have illustrated the performance of our proposed method by simulating the estimation of scaled mutation and recombination rates. The result shows that the proposed algorithm performs well.  相似文献

The question whether technological progress displaces employment or whether technological advance is beneficial for the level of employment has been at the core of economic debate for over two centuries. The beneficial effect might be achieved by several compensation mechanisms within the economic system. In this paper we categorize these compensation mechanisms into two basic categories that reflect the different nature of the ideas ruling the compensation. We discriminate the mechanisms of employment despite innovation from employment via innovation. In the context of new innovation economics we model an artificial industry implementing both compensation mechanisms. Simulation analysis is used to examine both the short–run and long–run properties of the model. There we focus on the influence of wage restraint policy on the functioning of the compensation mechanism.  相似文献

An experiment is discussed in which three computer-aided, interactive job shop scheduling approaches are compared using an interactive job shop scheduling simulator (JOB) developed for the project. All three approaches use a combination of computer and human capabilities to develop job shop schedules, but differ in terms of the timing and degree of human involvement required. The three scheduling approaches are (1) the successive approach, (2) the interactive approach, and (3) the semi-interactive approach. The successive approach is characterized by the computer scheduling all work orders without any human intervention. The interactive approach is distinguished by the human scheduling one work order at a time until all work orders are scheduled. The schedule is developed interactively by the person who must simultaneously consider work-order scheduling needs and machine group load capacities. The semi-interactive approach may be viewed as a combination of the successive and interactive approaches. Work orders are automatically scheduled one at a time using the successive approach criteria, but with prespecified machine-group load thresholds. As long as the load threshold is not exceeded, the successive approach is used to schedule work orders. When a threshold is exceeded, the algorithm (successive approach) pauses and human rescheduling (interactive approach) is required to rectify the overload situation. A second (reallocation) phase, identical for all three approaches, is used to overcome any scheduling problems generated in phase one. Experimental results based on nine different performance criteria (including scheduling time, makespan, machine group utilization, and work-in-process inventory) and 45 experimental runs indicate that there are differences between the results produced by the three scheduling approaches. The interactive approach yields the best overall scheduling results, but the other two approaches are clearly better than the interactive approach in some situations. The success of the interactive approach indicates that it is usually best for the human scheduler to become involved early in the computer-based job shop scheduling process.  相似文献

This study develops a heuristic procedure for decision making coordination in a decentralized organization structure. The procedure consists of simplified rules of iterative communication between decentralized units and a central agent. The central agent assigns budgeted profit levels and adjusts such levels guiding the system toward optimality. The decision making procedure developed in this study is compatible with management by objectives practices and can serve as a prototype for decentralized management.  相似文献
