张孝祥的思想颇多禅宗随缘妙悟的成分。其禅学思想主要来自于两个方面:一是宋代浓厚的的禅学氛围和禅宗学说;二是张孝祥家族笃信佛教的传统。张孝祥与禅宗的重要宗派临济宗的高僧多有交往,并崇信高僧大慧宗杲的学说。而其家族对佛教有虔诚的信仰,张孝祥自小耳濡目染,深受其影响。 相似文献

Micro‐enterprises, i.e. firms with less than 10 employees, are traditionally the hardest to engage in learning; they are also least likely to participate in such measures as business advice and guidance provision and initiatives to support information communication technology (ICT) adoption. Through a community‐based initiative initially targeting parents (unemployed or employed) to participate in ICT, 30 micro‐enterprises were attracted to learning for the first time. These companies had carefully avoided similar initiatives taking place locally, which emphasized business success and growth; they had only participated in this ICT skills training because of their children. The paper takes a case study approach to evaluate the reasons for participation, explores barriers and implications for those organizing similar activities, and calls for a more holistic view of owners and managers of small firms as fathers, mothers, etc. rather than just as ‘entrepreneurs’. 相似文献

The International Conference on Harmonisation guideline ‘Statistical Principles for Clinical Trials’ was adopted by the Committee for Proprietary Medicinal Products (CPMP) in March 1998, and consequently is operational in Europe. Since then more detailed guidance on selected topics has been issued by the CPMP in the form of ‘Points to Consider’ documents. The intent of these was to give guidance particularly to non‐statistical reviewers within regulatory authorities, although of course they also provide a good source of information for pharmaceutical industry statisticians. In addition, the Food and Drug Administration has recently issued a draft guideline on data monitoring committees. In November 2002 a one‐day discussion forum was held in London by Statisticians in the Pharmaceutical Industry (PSI). The aim of the meeting was to discuss how statisticians were responding to some of the issues covered in these new guidelines, and to document consensus views where they existed. The forum was attended by industry, academic and regulatory statisticians. This paper outlines the questions raised, resulting discussions and consensus views reached. It is clear from the guidelines and discussions at the workshop that the statistical analysis strategy must be planned during the design phase of a clinical trial and carefully documented. Once the study is complete the analysis strategy should be thoughtfully executed and the findings reported. Copyright © 2003 John Wiley & Sons, Ltd. 相似文献

我国家族企业“富不过三代”现象引起了人们的极大关注。笔者认为,家族式企业裂解的制度原因在于产权制度的排他性、委托代理的高风险性以及人才选拔的制度封闭性。 相似文献

家族企业管理模式变革的实证研究 总被引:1,自引:0,他引:1
文章简要回顾了国内外学术界对家族企业的研究成果 ,根据我国私营企业发展现状 ,提出了在现阶段我国家族企业发展的两个假设 ,即 :两权 (所有权和管理权 )所有的家族企业是私营企业创业时期的首选 ;制度环境 (市场体系完善、法律健全、文化先进等 )状况促进或阻碍家族企业两权分离的发生。并用理论和统计数据分析、实证了家族企业管理模式及其影响因素 相似文献

Summary. In many biomedical studies, covariates are subject to measurement error. Although it is well known that the regression coefficients estimators can be substantially biased if the measurement error is not accommodated, there has been little study of the effect of covariate measurement error on the estimation of the dependence between bivariate failure times. We show that the dependence parameter estimator in the Clayton–Oakes model can be considerably biased if the measurement error in the covariate is not accommodated. In contrast with the typical bias towards the null for marginal regression coefficients, the dependence parameter can be biased in either direction. We introduce a bias reduction technique for the bivariate survival function in copula models while assuming an additive measurement error model and replicated measurement for the covariates, and we study the large and small sample properties of the dependence parameter estimator proposed. 相似文献

We propose four different GMM estimators that allow almost consistent estimation of the structural parameters of panel probit models with fixed effects for the case of small Tand large N. The moments used are derived for each period from a first order approximation of the mean of the dependent variable conditional on explanatory variables and on the fixed effect. The estimators differ w.r.t. the choice of instruments and whether they use trimming to reduce the bias or not. In a Monte Carlo study, we compare these estimators with pooled probit and conditional logit estimators for different data generating processes. The results show that the proposed estimators outperform these competitors in several situations. 相似文献

家庭档案在人们社会生活中的重要作用日益凸显;就教育功能而言,突出地表现在家庭档案可以提供德智体、美育、心育等方面的教育内容;同时,家庭档案也是一种积极有效的教育手段:能促进自主学习与自我教育,有利于家庭积极参与社区教育和社会主义精神文明建设;能促进学校的教育教学工作,有利于家教合作。档案部门、家庭、学校等有关方面应积极协作,加强宣传力度,加强公众的档案意识,向公众提供建设家庭档案的业务指导,加强家庭档案的建设,以充分发挥其教育功能。 相似文献
