江泽民同志对文化纽带的两次深刻论述 ,主要是针对祖国统一和维护世界和平、促进共同发展的历史任务 ,强调了中华文化团结人民、凝聚人心的巨大作用。因此 ,文化纽带的内涵 ,实质就是中华文化的凝聚力问题。这是我们必须继承的宝贵精神财富 ,也是推进民族复兴大业的极为重要的力量 相似文献

Summary. Standard goodness-of-fit tests for a parametric regression model against a series of nonparametric alternatives are based on residuals arising from a fitted model. When a parametric regression model is compared with a nonparametric model, goodness-of-fit testing can be naturally approached by evaluating the likelihood of the parametric model within a nonparametric framework. We employ the empirical likelihood for an α -mixing process to formulate a test statistic that measures the goodness of fit of a parametric regression model. The technique is based on a comparison with kernel smoothing estimators. The empirical likelihood formulation of the test has two attractive features. One is its automatic consideration of the variation that is associated with the nonparametric fit due to empirical likelihood's ability to Studentize internally. The other is that the asymptotic distribution of the test statistic is free of unknown parameters, avoiding plug-in estimation. We apply the test to a discretized diffusion model which has recently been considered in financial market analysis. 相似文献

设Z_P={1,2,…,P-1,0},在模P的加法运算下,Z_P是一个群。Z_P上定义n维广义正方体,其顶点集为{(x_1,x_2,…,x_n):x_i∈Z_P.i=1,2,…,n},两个顶点x和y之间有一条棱,当且仅当sum from i=1 to n丨x_i-y_i丨=1 mod(P)。在这个定义下,本文证明了对任意P≥2和n≥2,Z_P中n维广义正方体上存在一个经过所有顶点的哈密顿回路。文中给出了一些例子作为应用。 相似文献

Several methods exist for the problem of testing the equality of several treatments against the one-sided alternative that the treatments are better than the control. These methods include Dunnett's test, Bartholomew's likelihood-ratio test, the Abelson-Tukey-Schaafsma-Smid optimal-contrast test, and the multiple-contrast test of Mukerjee, Robertson, and Wright. A new test is proposed based on an approximation of the likelihood-ratio test of Bartholomew. This test involves using a circular cone in place of the alternative-hypothesis cone. The circular-cone test has excellent power characteristics similar to those of Bartholomew's test. Moreover, it has the advantages of being simpler to compute and may be used with unequal sample sizes. 相似文献

What do we mean by progress and cumulation in the social and human sciences? Recent thinking in the philosophy and history of science has led to an abandonment of some versions of logical positivism and of verificationism that had a strong deductive and theory testing orientation. What is to replace them is less clear. This paper argues that progress and cumulation can be seen as a process of evaluation and retention within an epistemic community. Scholarly disciplines differ in their social structure and in their epistemic and normative commitments. Since sociology is a fragmented discipline, progress and cumulation differ within its multiple subdisciplines, which to varying extents represent epistemic communities. Brief sketches of progress (advance) and cumulation in several subdisciplines are offered. 相似文献

Clinical implications and ethical dilemmas of the use of confidential case material in clinical writing are examined, including
a review of the discourse among professionals who publish clinical work. This literature is applied to a clinical illustration
of psychotherapy with a client who gave consent for publication and read the clinical write-up of her case material. It is
suggested that clinical writing may increase client “self-reflection” if there is a “secure base” of attachment between therapist/author
and the client. The impact on the client’s treatment process is examined, in addition to a discussion of ethical questions
and professional recommendations.

This article provides a discursive perspective on the dilemmas of sameness and difference feminisms and their consequences for change projects. It explores how equal opportunity officers dealing with gender issues and introducing equality legislation in practice construct the meaning of equal opportunities. The analysis of the interpretative repertoires and ideological dilemmas drawn upon in ten interviews shows the highly context‐specific use of four different repertoires constructing gender equality: the sameness, difference, bandwidth and deconstructive repertoire. Interpreting the shifts between repertoires from the perspective of the ideological dilemma, new avenues for change are explored. The article concludes that the simultaneous use of all possible theoretical perspectives might be a worthwhile objective. 相似文献

Summary This paper solves some D-optimal design problems for certain Generalized Linear Models where the mean depends on two parameters
and two explanatory variables. In all of the cases considered the support point of the optimal designs are found to be independent
of the unknown parameters. While in some cases the optimal design measures are given by two points with equal weights, in
others the support is given by three point with weights depending on the unknown parameters, hence the designs are locally
optimal in general. Empirical results on the efficiency of the locally optimal designs are also given. Some of the designs
found can also be used for planning D-optimal experiments for the normal linear model, where the mean must be positive.

深化对劳动和劳动价值论问题的认识 ,是由马克思主义与时俱进的理论品质和劳动价值论的地位决定的 ,是迎接理论挑战和实践挑战的需要。通过深化对生产劳动、科技劳动和经济管理劳动的认识 ,有利于丰富劳动概念的内涵 ,拓展生产劳动的范围 ,明确科技和经营管理劳动不仅是生产性劳动 ,而且在价值和社会财富的创造中发挥着巨大的作用。 相似文献
