A number of reasons have been suggested for the rapid decline in influence and credibility experienced by William McDougall after his arrival in America. To obtain some evidence on this issue, all articles appearing in The New York Times between 1906 and 1940 in which McDougall was mentioned were coded for the nature of the image conveyed. Articles mentioning the two authors most similar to McDougall in terms of number of citations, Joseph Jastrow and Edward L. Thorndike, were also coded for the nature of the image conveyed. In contrast to the images of Jastrow and Thorndike, the image McDougall conveyed was significantly more negative. McDougall was more often satirized, and references to McDougall were significantly less likely to be simple reporting of something he had said or done. Results are discussed in terms of the role of the press in "deciding" controversies in which the scientific community has lost interest.

Detailed examination of the lifetimes of components and assemblies by means of the usual sequential probability ratio tests is often not feasible because of the prohibitive time or cost involved in such an examination. Situations commonly arise, however, where extraneous information is available (perhaps in the form of experience of similar situations or concerning the reputation of the supplier of the components or assemblies) which reflects on the current situation. Such information might be incorporated in a Bayesian analysis, but little work seems to have been done in this area. This paper presents a possible sequential life test incorporating prior information, applied to the simplest situation of components with exponentially distributed lifetimes, tested individually. The results for conventional sequential lifetests are used as a rough yardstick against which to measure the properties of the Bayesian lifetest discussed in the paper. 相似文献

This article examines some of the announcements and advertisements that Camille Silvy placed in the English press during the nine years he spent as one of London's foremost commercial portraitists. The article also looks at some other occurrences of Silvy's name in a variety of newspapers and journals and discusses the new light that these sources shed on Silvy's business practices and on the history of his studio. 相似文献

In this paper, the reliability of a system with N independent components supplied with a pool of s spares is investigated. The components have an exponential life time distribution and the failed components are repaired, one at a time, with a general repair time distribution. Numerical results are presented for the mean time to system failure (system is said to fail when a component fails with no spare available) and the reliability of the system in some special cases of interest. 相似文献

In this paper, we consider the detailed characteristics of the standard sequential test of a simple hypothesis versus a single alternative for the case of the binomial distribution. A method is developed which permits evaluation of the associated probabilities of acceptance and/or rejection of the null hypothesis at each stage. From this information, the quantitative features of the test (Operating Characteristic and test termination probability) are completely determined. Curves are presented to facilitate assessment of the sequential procedure in practical cases. A sequential test is compared with a fixed sample size test having approximately the same Operating Characteristic. Wald's approximation for the average sample number is compared with exact values. 相似文献
