This paper refutes the proposition by Caplan and Gochenour that there is no such thing as natural resources because all goods are produced. Caplan and Gochenour use that proposition to argue against the reform proposal of Henry George and his followers, to replace all taxes with a single tax on land value. The rebuttal to Caplan and Gochenour made by this paper is that the discovery of a resource does not constitute its production. The refutation here argues that entrepreneurship and investment create human capital and capital goods, not natural resources. Discovery is not the same as invention or production.  相似文献

The global economy is a reality. The challenge facing international human resource management (IHRM) is not whether to use widely recognized HR concepts and techniques but rather how to effectively adapt and fit them across cultures. The purpose of this article is to suggest and demonstrate a contingency matrix approach to IHRM. After first explaining what is meant by the contingency matrix approach, the remainder of the article uses a sampling of the HR research literature from Japan, Germany, Mexico, and China to show how a contingency matrix could be used for effective IHRM. © 1997 John Wiley & Sons, Inc.  相似文献

Several new product development (NPD) scholars have argued that formal processes should be used when selecting incremental new product ideas for advancement at the very beginning of the fuzzy front end (FFE), but that such formal processes may be less beneficial when selecting radical new product ideas. However, arguments also exist for using formal idea selection processes for both types of new product ideas. In practice, informal processes are used for selecting both idea types and more formal processes are used for selecting radical ideas. Unequivocal empirical evidence for either of the opposing views or practices is lacking. This study sheds light on this matter using data from 161 of the firms that participated in the Product Development and Management Association's latest (2012) Comparative Performance Assessment Study. The results reveal that the highest idea success rate (i.e., the proportion of selected ideas that are eventually launched as new products and are successful in the marketplace) is associated with firms’ use of formal processes to select the vast majority of both incremental and radical new product ideas for advancement. This finding supports earlier claims that even for (raw) idea selection processes that take place at the very beginning of the FFE, managers need to adopt a portfolio perspective and consistently use formal idea advancement selection processes to ensure attaining the right balance between radical and incremental projects in later stages of the NPD pipeline to enhance overall NPD success. Notably, this finding shows that common managerial practices of using inconsistent approaches for selecting radical and incremental ideas for advancement need to be reconsidered.  相似文献

Metrics addressing process safety incident performance typically focus on frequency and severity statistics. Often, these lagging metrics are not overly sensitive to actual performance, making trending and forecasting difficult. This article presents the results from a statistical study of a large incident dataset where changes in the Pareto shape parameter were observed as a function of time. This approach has been found to give far better insight into process safety performance than traditional incident metrics and readily relates back to concepts such as the “incident triangle” and “layers of protection.” Through the application of this approach, trends within process safety incident performance have been observed earlier, and more accurate forecasting has allowed for the identification of anomalies. In turn, these critical observations have allowed for the better structuring and targeting of process safety programs. Although incident data are generally considered as a lagging indicator, this approach has clearly reduced the lag time associated with this type of data and has given valuable insight into the current status of process safety performance. © 2009 American Institute of Chemical Engineers Process Saf Prog 2009  相似文献
