The DEDICOM model is a model to analyze square tables describing asymmetric relationships among n entities. Its importance in the asymmetric multidimensional scaling literature is due to the fact that several authors showed a large class of models to be simply a constrained version of DEDICOM. A typical example is the Generalized GIPSCAL proposed by Kiers & Takane. In this paper we present a new algorithm capable to fit, in the least squares sense, any DEDICOM constrained model. 相似文献

We investigate the properties of several statistical tests for comparing treatment groups with respect to multivariate survival data, based on the marginal analysis approach introduced by Wei, Lin and Weissfeld [Regression Analysis of multivariate incomplete failure time data by modelling marginal distributians, JASA vol. 84 pp. 1065–1073]. We consider two types of directional tests, based on a constrained maximization and on linear combinations of the unconstrained maximizer of the working likelihood function, and the omnibus test arising from the same working likelihood. The directional tests are members of a larger class of tests, from which an asymptotically optimal test can be found. We compare the asymptotic powers of the tests under general contiguous alternatives for a variety of settings, and also consider the choice of the number of survival times to include in the multivariate outcome. We illustrate the results with simulations and with the results from a clinical trial examining recurring opportunistic infections in persons with HIV. 相似文献

This article presents a teaching concept that lets students of the educational fields acquire counselling qualifications along with their curriculum. The importance of offering this course at the university of Hamburg, where a first test-run is conducted, is discussed. Further, the theoretical background, course contents and structures of the planned addition qualification “educational counselling and psycho-educative coaching” are shown. Finally, the current implementation and its progression is described together with an accompanying survey. 相似文献

The influence of the social situation on the physical distance and, as measured by a questionnaire, emotional intimacy between participants was experimentally studied (N = 90) in a cooperative, a competitive, and a neutral social situation. Results indicate that the physical distance was greatest under neutral conditions. The cooperative condition produced the strongest feeling of intimacy. It is argued that the neutral condition is irrelevant to the participants’ behaviour and level of attention to other persons. Further, intimacy can only arise if an interaction is both positive and relevant. The correlation between physical and emotional distance turned out to be relatively small, in accordance with the range usually given for attitudebehaviour correlations. 相似文献

随着学习“三个代表”、实践“三个代表”的深入 ,“三个代表”思想如何进课堂是马克思主义理论课教学面临的现实问题。要讲清理论 ,掌握群众 ,体现“三个代表”思想的创新蕴意 ,必须解决好理论的“权威”与“维权”的矛盾 ;课堂中可能出现的“讲清”与“清讲”的矛盾 ;必须着眼于理论思维 ,全面梳理“三个代表”思想。 相似文献

Quality Management: History, problems and an integrative modelStarting with a critical examination of the history and the commonly known concepts and systems of Quality Management, the paper discusses a broader understanding of quality in a genuinely managerial perspective. This is shown by generating and applying five basic dimensions of the quality concept. An integrative concept of Quality Management is presented. 相似文献

进化论对中国近代国人的影响是多方面的.文章以胡适为例,探讨进化论在当时文学界产生的争论和影响.胡适以"一时代有一时代的文学"为主要内容的历史进化文学观念,有力地推动了白话文学的发展.由此引起的争论,使新文学借助于后胜于今的进化论与传统文学发生裂变,并与百年来的中国现代化进程紧紧地纽结在一起. 相似文献
