A wide selection of classical and recent tests for exponentiality are discussed and compared. The classical procedures include the statistics of Kolmogorov-Smirnov and Cramér-von Mises, a statistic based on spacings, and a method involving the score function. Among the most recent approaches emphasized are methods based on the empirical Laplace transform and the empirical characteristic function, a method based on entropy as well as tests of the Kolmogorov-Smirnov and Cramér-von Mises type that utilize a characterization of exponentiality via the mean residual life function. We also propose a new goodness-of-fit test utilizing a novel characterization of the exponential distribution through its characteristic function. The finite-sample performance of the tests is investigated in an extensive simulation study.Received: January 2002/Revised: January 2004 相似文献

Although certain researchers have attributed widespread lottery play to irrational beliefs that people hold regarding the chances of winning the lottery, another explanation for the popularity of lottery gambling is that lottery players may experience positive emotions before the draw. Therefore, in this study, we examine the relationship between lottery participation and happiness. Using data from the British Gambling Prevalence Survey 2010 and utilizing propensity score matching methods, we find a small positive effect of lottery participation on happiness for individuals who engage in lottery play for recreational purposes. 相似文献

While it has long been recognised that the process of development is necessarily linked to technology, the question of the efficiency of technological spillovers from foreign direct investment remains controversial. The following paper examines the theoretical background and then focuses on the case of Mexico, analysing the technological performance of multinational enterprises in that country. 相似文献

This paper covers the main findings of the doctoral research that was concerned with seeking to extend aspects of dilemma
theory. In professional practice, the Trompenaars Hampden-Turner Dilemma Reconciliation ProcessTM is a vehicle delivering dilemma theory in application. It informs a manager or leader on how to explore the dilemmas they
face, how to reconcile the tensions that result, and how to structure the action steps for implementing the reconciled solutions.
This vehicle forms the professional practice of the author who seeks to bring more rigor to consulting practice and thereby
also contribute to theory development in the domain. The critical review of dilemma theory reveals that previous authors are
inconsistent and variously invalid in their use of the terms ‘dilemma theory,’ ‘dilemma methodology,’ ‘dilemma process,’ ‘dilemma
reconciliation,’ etc., and therefore an attempt is made to resolve these inconsistencies by considering whether ‘dilemmaism’
at the meta-level might be positioned as a new paradigm of inquiry for (management) research that embodies ontological, epistemological,
and methodical premises that frame an approach to the resolution of real world business problems in (multi) disciplinary;
(multi) functional and (multi) cultural business environments. This research offers contributions to knowledge, professional
practice and theory development from the exploration of the SPID model as a way to make the elicitation of dilemmas more rigorous
and structured and in the broader context of exploring ‘dilemmaism’ as a new paradigm of inquiry. 相似文献

The risk to human consumers from contaminants in fish is often dealt with by issuing consumption advisories, or in some cases, information brochures. Normally advisories and brochures are developed and tested with anglers. We examine the efficacy of a fish consumption brochure that was developed for pregnant women on people engaged in fishing in the Newark Bay Complex. The brochures were in English and Spanish, and subjects could read and be interviewed in either language. Of the 151 people interviewed, 32% were women, 58% spoke only English, 22% spoke mainly Spanish and the rest felt comfortable with both languages. There were no differences in the percent that were present as a function of preferred language. There were significant differences in the understanding of the brochure, depending upon preferred language (and the language of the brochure). In general, anglers preferring Spanish and who read the brochure in Spanish obtained fewer of the messages correctly than those who preferred English (seven of seven questions). There were also gender differences in efficacy of the brochures; a higher percentage of female anglers thought that the fish were not safe to eat from the port and thought that eating contaminated fish from the port could harm their baby. Although the correct message was obtained by 34–100% of the anglers, depending upon the question, and 60–75% of the anglers believed the pamphlet, only 16% (Spanish‐speaking) to 47% (Bilingual) planned on changing the species of fish they eat or the method of cooking. These data suggest that a pamphlet designed for pregnant women is useful for anglers, and they can obtain the ‘correct’ message from it. However, a relatively small percentage of subjects were persuaded to change their cooking or consumption behavior. In addition to television, subjects felt that the direct approach of distributing brochures face‐to‐face was an important method of communication of fish consumers. 相似文献
