This paper discusses the relationship between business process reengineering and channel performance for firms implementing electronic data interchange (EDI) linkages within the U.S. grocery industry. Both quantitative and qualitative data sources are combined to test the hypothesis that channel transformation involving adoption of EDI and redesign of replenishment processes enables performance improvements more than an order of magnitude greater than implementation of EDI alone. This new process, enabled by EDI, provides retailers with 50- 100% higher inventory turns for products on continuous replenishment processes (CRP) relative to retailer performance using traditional ordering processes. Firms adopting EDI without using CRP to reengineer the ordering processes have failed to realize any statistically significant improvements in either inventory levels or warehouse stockouts. This research provides evidence to support the claims of process reengineering that are common in the popular business press, but for which statistically significant empirical evidence is minimal. The findings of the research also demonstrate the potential improvements that firms can realize through extending the business process reengineering concept to include the firms' entire supply chain. 相似文献

Abstract. A stochastic epidemic model is defined in which each individual belongs to a household, a secondary grouping (typically school or workplace) and also the community as a whole. Moreover, infectious contacts take place in these three settings according to potentially different rates. For this model, we consider how different kinds of data can be used to estimate the infection rate parameters with a view to understanding what can and cannot be inferred. Among other things we find that temporal data can be of considerable inferential benefit compared with final size data, that the degree of heterogeneity in the data can have a considerable effect on inference for non‐household transmission, and that inferences can be materially different from those obtained from a model with only two levels of mixing. We illustrate our findings by analysing a highly detailed dataset concerning a measles outbreak in Hagelloch, Germany. 相似文献

Abstract Temporary staffing has joined the ranks of the globalizing service industries. The largest agencies have now established a presence in more than sixty nations, where they are placing employees in temporary positions across a range of occupations, from clerical, cleaning and light industrial work through to accountancy, law and IT. The opening up of new occupational and geographical markets around the world has been driven by the imperative to sustain growth in sales volumes, in this business of tight margins and fierce competition. The most lucrative of the staffing industry's ‘emerging markets’ are found in the actively deregulating economies of the global North ‐ including Spain, Germany, Italy and Japan. While exploring how the staffing industry has been active in the construction of these markets, we argue that this fast‐growing business has become an important agent of labour market liberalization. 相似文献

An area of international communication research that has beenlargely overlooked is the extent to which a message originatingin one country is understood by receivers in another country.The study described in this article tested the construct validityof Darnell's clozentropy procedure as a measure of monolingualinternational communication comprehension. Results of the studystrongly support the procedure. 相似文献

MORTGAGE LENDING TO MINORITIES: WHERE'S THE BIAS? 总被引:1,自引:0,他引:1
This paper examines mortgage lending and concludes that studies based on data created by the Boston Fed should be reevaluated. A detailed examination of these data indicates that irregularities in these data, when combined with the most commonly used research methodology, appear to have biased previous research toward a finding of discrimination against minority applicants. When the most severe data irregularities are eliminated, evidence to support a hypothesis of discrimination disappears. The currently fashionable "flexible" underwriting standards of mortgage lenders may have the unintended consequences of increasing defaults for the "beneficiaries" of these policies.

Journal rankings published by Journal Citation Reports (JCR) are widely used to assess research quality, which influences important decisions by academic departments, universities, and countries in the allocation of research funds. We study refereed law journal rankings by JCR and Washington and Lee Law Library (W&L). JCR's rankings are uncorrelated with W&L's. The differences appear to be attributable to underrepresentation of law journals in JCR's database. We illustrate the effects of database bias on rankings through case studies of three elite journals, the Journal of Law and Economics, Supreme Court Review, and the American Law and Economics Review.
