Models for measuring and benchmarking olympics achievements

As demonstrated in several recent studies, data envelopment analysis (DEA) is a useful tool for evaluating and comparing the performance of nations competing in the Olympic Games. Assurance regions (ARs) have been used to further refine the DEA results. These AR DEA models assume that ARs apply uniformly across all nations. Such models can have shortcomings in the sense that different nations may impose different ARs, as nations may value gold, silver, and bronze medals differently. This paper extends previous DEA studies by incorporating multiple sets of nation-specific ARs into the DEA. By doing so, we establish fair models for measuring and benchmarking the performance of nations at six summer Olympic Games.     

企业持续改进的组织行动模型实证研究

在复杂多变的全球化环境中,制造类企业面临激烈的竞争,这要求企业实施持续改进的先进管理模式。但企业中的各项改进活动应如何进行、由谁负责,则成为持续改进执行过程中的难点,故提出对持续改进绩效有显著正向影响的不同主体的三类组织改进活动,据此针对组织改进活动和持续改进绩效之间的关系建立了模型,并利用Continuous Innovation Network(CINet)等数据库的数据进行了结构方程模型的实证。结果表明,其拟合优度指数满足要求,模型比较理想。组织在持续改进过程中可将模型中的三类活动作为重点,逐步开展持续改进的各项活动,提高组织绩效,进而全面实现持续改进。     

Organizational learning in SMEs’ internationalization: A moderated mediating effect of absorptive capacity

We examine both mediation and moderation effects on the direct relationship between internationalization speed and firm performance in the context of small and medium-sized enterprises (SMEs). Building on prior studies that focus either on the direct speed–performance linkage or the moderating role played by knowledge, we suggest that an important source of performance variations is organizational learning. Grounded in the organizational learning perspective, we argue that firm strategies regarding speed and earliness of internationalization provide the SMEs with opportunities to develop their absorptive capacity, and thus enhance their performance. Using survey data from 343 SMEs in Australia and New Zealand, our empirical results suggest that absorptive capacity is associated with internationalization speed in a reversed U-shape relationship and that in turn absorptive capacity mediates the direct speed–performance relationship. Moreover, this mediating effect is moderated by earliness of internationalization. By demonstrating the moderated mediating effect of absorptive capacity as a novel mechanism to achieving superior performance, we enhance the understanding of how firms succeed internationally.     

企业人力资本管理研究

在知识经济时代,企业之间的竞争更多地表现为企业所拥有的人力资本间的竞争。那么,企业怎样才能有效地管理好内部的人力资本呢?本文运用新制度经济学的研究工具,首先从人力资本专用程度、人力资本信息分布状况和人力资本管理的成本与收益三个方面提出了分析框架。然后,按转移成本和对企业依赖程度的不同,把人力资本分为通用性人力资本、专用性人力资本和准专用性人力资本三类,并对每一类人力资本的管理进行了研究。

Evaluation of Embedded Intelligent Real‐time Systems*

Over the past two decades, questions have surfaced about the effectiveness and contribution of intelligent systems to decision makers in a variety of settings. This paper focuses on the evaluation challenges associated with intelligent real‐time software systems that are embedded in larger host systems. With the proliferation of such systems in operational settings such as aerospace, medical, manufacturing, and transportation systems, increased attention to evaluations of such systems, and to resulting software safety, is warranted. This paper describes one such evaluation and proposes a set of evaluation criteria for embedded intelligent real‐time systems (EIRTS). Implications of the evaluation and the evaluation criteria are discussed.

资源异质性如何影响企业绩效:资源管理能力调节效应的检验和分析

战略理论认为,资源与能力是引致企业竞争优势和绩效差异的重要因素,但鲜有实证研究探讨异质性资源与何种企业能力组合可提升企业绩效的问题。本文通过定量研究分析了资源异质性与资源管理能力不同维度组合对企业绩效影响的效果。数据分析结果表明,资源获取、整合与释放能力维度对资源异质性正向影响企业绩效的作用关系有调节作用,但对不同的资源特质—绩效关系影响程度不同。本研究揭示了资源异质性—企业绩效关系成立的边界条件和影响因素,对企业管理实践有重要意义。     

Supplier integration and company performance: A configurational view

Supplier integration is considered a key managerial strategy for improving buyer performance. This study adopts a configurational approach to supplier integration, based on the interaction and complementarity between supply chain management practices. In this perspective, this study explores the impact of supplier integration and measures aimed at creating a fast supply network structure on buyer performance. This research also attempts to ascertain whether these practices can exert a synergic effect. After examining data from a sample of 186 manufacturing plants, we can conclude that while taken singly supplier integration and fast supply network structure practices have a markedly positive effect on the performance goals considered (i.e., efficiency, schedule attainment and flexibility); in addition, they interact to produce an additional synergic effect on efficiency and schedule attainment. The analyses also reveal that investing in FSNS or SI initiatives alone can be risky. On one hand, when companies fail to make any effort to structure their supply network in order to achieve fast lead times, the impact of supplier integration on efficiency and schedule attainment may be hindered and, in extreme cases, supplier integration might even have no impact at all. On the other hand, investing only in fast supply network structure initiatives, without striving to achieve an adequate level of supplier integration might well be useless: indeed, even detrimental to any improvement in performance. These findings provide useful guidelines for managers who must decide how to combine supplier integration and fast supply network structure initiatives in order to improve or maximize performance.
