"自我"的问题,在中国文化体系中一直是一个敏感的问题.透过中国传统文化中关于自我观的现象,分析了关于"自我"的理念.提出了"自我观"在中国传统文化中的"道德化"倾向,以及"道德化自我"演变成"泛道德化自我"的极端状态的基本历程.同时,从文化学的角度论述了确立正确的"自我观"所要处理好的三个关系,即德性与才性的关系、个体与社会的关系、科学与人文的关系. 相似文献

中国农村发展水平因子分析 总被引:1,自引:0,他引:1
"三农"问题已成为制约中国经济社会发展的瓶颈性因素,而要有效地解决"三农"问题,首先要对中国不同地区农村发展水平做出相对客观的评价。选取一系列的评价指标,运用多元统计分析中的因子分析方法,30个省区的农村发展水平作整体综合分析,得出各地区农村发展水平的概况,并在此基础上指出了各地区解决农村发展问题的重点。 相似文献

在调整我国刑事庭审的"诱导性规则"里,诱导性询问仅被赋予消极的内涵而遭禁绝,从而直接影响了刑事庭审中司法公正、效率等多元价值的实现.在较为均衡的价值观的指导下,借鉴对抗制国家的立法经验,建立完善的符合我国实际的诱导性规则,是刑事庭审方式改革的当务之急. 相似文献

When estimating the distributions of two random variables, X and Y, investigators often have prior information that Y tends to be bigger than X. To formalize this prior belief, one could potentially assume stochastic ordering between X and Y, which implies Pr(X < or = z) > or = Pr(Y < or = z) for all z in the domain of X and Y. Stochastic ordering is quite restrictive, though, and this article focuses instead on Bayesian estimation of the distribution functions of X and Y under the weaker stochastic precedence constraint, Pr(X < or = Y) > or = 0.5. We consider the case where both X and Y are categorical variables with common support and develop a Gibbs sampling algorithm for posterior computation. The method is then generalized to the case where X and Y are survival times. The proposed approach is illustrated using data on survival after tumor removal for patients with malignant melanoma. 相似文献

Recurrent events are frequently observed in biomedical studies, and often more than one type of event is of interest. Follow-up time may be censored due to loss to follow-up or administrative censoring. We propose a class of semi-parametric marginal means/rates models, with a general relative risk form, for assessing the effect of covariates on the censored event processes of interest. We formulate estimating equations for the model parameters, and examine asymptotic properties of the parameter estimators. Finite sample properties of the regression coefficients are examined through simulations. The proposed methods are applied to a retrospective cohort study of risk factors for preschool asthma. 相似文献

The complex Bingham distribution is relevant for the shape analysis of landmark data in two dimensions. In this paper it is shown that the problem of simulating from this distribution reduces to simulation from a truncated multivariate exponential distribution. Several simulation methods are described and their efficiencies are compared. 相似文献

Regression models for survival data are often specified from the hazard function while classical regression analysis of quantitative outcomes focuses on the mean value (possibly after suitable transformations). Methods for regression analysis of mean survival time and the related quantity, the restricted mean survival time, are reviewed and compared to a method based on pseudo-observations. Both Monte Carlo simulations and two real data sets are studied. It is concluded that while existing methods may be superior for analysis of the mean, pseudo-observations seem well suited when the restricted mean is studied. 相似文献

陈马癸《文则》考察修辞现象的方法至今仍有意义。着眼于汉语修辞学史 ,从“假之以渔”,而不是“假之以鱼”的角度 ,可发现《文则》中蕴含着素朴的辩证综合法、直观分析法、有限演绎法 ,实在难能可贵 ,值得今人批判地继承 相似文献

Probabilistic risk analyses often construct multistage chance trees to estimate the joint probability of compound events. If random measurement error is associated with some or all of the estimates, we show that resulting estimates of joint probability may be highly skewed. Joint probability estimates based on the analysis of multistage chance trees are more likely than not to be below the true probability of adverse events, but will sometimes substantially overestimate them. In contexts such as insurance markets for environmental risks, skewed distributions of risk estimates amplify the "winner's curse" so that the estimated risk premium for low-probability events is likely to be lower than the normative value. Skewness may result even in unbiased estimators of expected value from simple lotteries, if measurement error is associated with both the probability and pay-off terms. Further, skewness may occur even if the error associated with these two estimates is symmetrically distributed. Under certain circumstances, skewed estimates of expected value may result in risk-neutral decisionmakers exhibiting a tendency to choose a certainty equivalent over a lottery of equal expected value, or vice versa. We show that when distributions of estimates of expected value are, positively skewed, under certain circumstances it will be optimal to choose lotteries with nominal values lower than the value of apparently superior certainty equivalents. Extending the previous work of Goodman (1960), we provide an exact formula for the skewness of products. 相似文献
