a lesson from all our yesterdays

The rise of unemployment to close to three million recalls memories of the dole queues of the 1930s. Kent Matthews, of the Cardiff Business School, explores the analogies between the unemployment of the 1930s and the 1990s.     

THE EFFECT OF INVESTMENT IN INTERORGANIZATIONAL INFORMATION TECHNOLOGY IN A RETAIL SUPPLY CHAIN

The primary purpose of this research was to investigate the effect of investment in information technology in a supply chain. The results of that investigation are presented by focusing on an empirically tested supply chain relationship model containing both behavioral and operational constructs. The four behavioral constructs represented in the model are relationship trust, relationship commitment, relationship dependence, and long‐term relationship orientation. The four operational constructs represented in the model are retailer investment in interorganizational information technology, perceived supplier investment in interorganizational information technology, logistics efficiency, and logistics effectiveness. Among other findings, the results of the investigation found that perceived supplier investment in interorganizational information technology has a significant and positive effect on logistics efficiency.     

Rafting the River: A Risk Management Expert System for Dynamic Problem Solving

Commercial project management systems focus on preproject planning and after-the-fact documentation, but not on the dynamic problem solving required in day-to-day project management. Yet the need for risk-oriented management is clear. To understand and control project risks, managers must be able to identify problems as they occur, immediately assess their downstream impacts, and plan a course of action. The Advanced Risk Management System (ARMS) is a prototype system built to address the issues of identifying, analyzing, prioritizing, monitoring, and controlling project risk. ARMS uses expert systems, data base management, and hypermedia technologies to capture and classify project schedule problems, to determine their semantic impacts to future activities, and to alert appropriate project personnel in advance of problem occurrence.     

Explaining the Cross‐Section of Stock Returns in Japan: Factors or Characteristics?

Japanese stock returns are even more closely related to their book-to-market ratios than are their U.S. counterparts, and thus provide a good setting for testing whether the return premia associated with these characteristics arise because the characteristics are proxies for covariance with priced factors. Our tests, which replicate the Daniel and Titman (1997) tests on a Japanese sample, reject the Fama and French (1993) three-factor model, but fail to reject the characteristic model.     

Developing a tutoring module for presentation of computerized patient management problems

The simulation problem is one of the most commonly used formats in computer-assisted instruction (CAI). In medical education, a patient simulation problem is known as a patient management problem (PMP). A number of computerized PMP systems are currently available. However, to date, there is no record of PMP systems having been developed using artificial intelligence. This is noteworthy since artificial intelligence techniques could help in the generation of more effective and intelligent instructional systems.

This paper analyzes and evaluates existing instructional simulation software in clinical medicine in terms of effective educational design attributes. Components of effective PMP systems thus identified are incorporated into a computerized instructional system which uses artificial intelligence techniques for teaching problem-solving and diagnostic skills to undergraduate medical students.     

本土化和全球化并存下的企业责任和公司治理(英文)

近几年,公司治理日渐成为新的研究热点,吸引了各界广泛的兴趣。从传统意义上说,公司治理研究的是不同国家背景下的企业内部决策权分配的问题。本文却旨在超越传统观念,试图将公司治理概念与日益凸显的全球化统一起来。 为更好地探讨新的公司治理形式,我们粗泛地把它定义为：多重参与者影响下的、聚焦于企业合法利用国内外资源的企业战略决策。此定义带有与“战略方向”意义相一致的内涵。两者均承认治理决策对企业战略方向有影响,后者决定了企业和股东能否获得好的投资回报。 在战略管理领域,“公司治理专注于解决公司内部决策权分配的问题”（Gollis 和 Montgomery,1997）是一个被广泛接受的观点。传统观点认为,企业决策权的制定应局限于对企业资源有明确主张的内部利益相关者,而今,越来越多的人认识到企业外部的利益相关者也应获得企业决策权的合法权（Hill 和 Jones,2007）。尽管拓宽后的公司治理概念（也就是说,超越企业边界的社会群体与从中选举产生的董事会影响企业资源配置的决策权）常被归入企业社会责任范畴;可一量考虑到企业社会责任涵盖经济,生态和社会等内容,公司治理概念的外延也随之变得广阔起来——它要解决的问题不仅包括如何为公司股东聚焦财富,同时也包括如何对自然与社会环境施加直接的影响。 让我们把基本假设阐述得更清晰些。首先,政府的三个层面,即联邦、州（或省）及地方,对公司治理的影响是有效且关联的;其次,国际关系的描述性效用（可识别为各国基于企业资源决策的竞争性互动）对公司治理的影响越发显著。考虑到影响战略方向与绩效的国际层面互动,我们假设,除了三个传统的政府层面外,还存有重要性不弱于前者的第四层面（称其为超国家层面或许更恰当）。在此层面上,有众多影响企业治理的参与另两种组织（跨国公司、非政府组织）进行了详细讨论。 很明显,跨国公司、非政府组织是影响公司治理的新要素,它的出现已得到文献详细论述（Dah 和Jeegen,2003）。随着非政府组织影响的延展,要掌握当代公司治理的演化,我们需对“全球”和“本土”等几组概念进行扩展。举例而文言主,从“本土”视角看,拉丁美洲仅意味着地球的某一特定方位,如果拉丁美洲真的与世隔绝,用“本土”描述这一时空统一体当然是正确的。然而,由于快速沟通的实现,尤其是互联网的出现,只要点击鼠标,“本土”即刻成为了“全球”。因此,“本土”和“全球”合而为一是全球化的结果。 非政府组织领导者非常清楚全球性的根本改变,他们利用这种改变来增强自己的优势,并依据即定目标最大地发挥该组织的影响力。利用互联网的信息传播或是CNN的新闻报道,基于很低的成本,“绿色和平”组织可在几秒内把一件地区性小事（村落传闻）变成全球性大事（国际流言）。有鉴于此,“本上”不仅仅是方位,它还是发生在这个方位上的所有事件,而这些事件能迅速转化为国际性焦点。无疑,本土和全球已融为一体,我们也必须将他们视为一体。 为进一步阐明公司治理近几年已发生根本变化的观点,本文运用三个安全例来支持这种改变是如何在利益相关者试图影响公司战略方向的情况下发生的。案例一讲述执行墨西哥组装工厂计划的跨国公司回应关于外界呼吁其自主披露战略导向的故事。案例二描写的是沃尔玛在美国某社区建立分店的意图遭非政府组织与当地市民反对而最终落败的历程。案例三介绍多元化的利益相关者（政府、非政府组织、跨国公司、联合国等）如何通过国际制裁、国内立法和行业自治等手段以保护钻石产业免受战略性威胁。     

Revisiting managerial perspectives on dividend policy

We survey managers of Nasdaq firms that consistently pay cash dividends to determine their views about dividend policy, the relationship between dividend policy and value, and four common explanations for paying dividends. The evidence shows that managers stress the importance of maintaining dividend continuity and widely agree that changes in dividends affect firm value. Managers give the strongest support to a signaling explanation for paying dividends, weak to little support for the tax-preference and agency cost explanations, and no support to the bird-in-the-hand explanation. The study provides new evidence about how managers view dividend life cycles and residual dividend policy. The authors would like to thank two anonymous referees for helpful comments and suggestions, and Maheshan Fernando and Sumeet Chawla for providing research assistance.     

A generalized lot sizing model for the process cycling problem

Most scheduling/lot sizing models for the single-machine problem assume that aggregate demand equals aggregate production; and that backorders are to be avoided. Where working inventories are low, the scheduler may wish to avoid short production runs and willingly incur some backorder penalties so as to increase the length of production runs and reduce setup costs per unit of time. The model proposed here identifies optimal lot sizes with respect to the backorder/setup cost relationships. Use of the model will result in an optimally balanced inventory even when aggregate inventory levels are changing.
