马克思主义中国化是过程与结果的统一,过程产生结果,结果来自过程.立足过程本身,多维透视马克思主义中国化过程,探索其中文化选择、思想斗争、实践运用、理论创新、问题解决等不同方面的历史运动过程,无疑有助于深入认识马克思主义中国化的理论本质和实践逻辑. 相似文献

Nonparametric test statistics are constructed by considering the medians in subsamples of appropriate size taken -from n independent observations. These tests are shown to be sensitive to both heavy and moderate tailed distributions. 相似文献

In this paper we consider the problem of obtaining best linear unbiased estimators of individual response coefficients in a Random Coefficient Linear Regression (RCR} Model, comparing alternative estimators for these response vectors through a simulation study. We also provide an empirical example that illustrates the estimation procedure proposed here. 相似文献

A simple adaptation of a distribution-free method due to Scholz (1978) and Sievers (1978) for inference in a single regression setting is proposed for inference about the difference in slopes of two regression lines. We assume that the data are obtained from a designed experiment with common regression constants. A comparison of the proposed method to its competitors-one due to Hollander and the other due to Rao and Gore-indicates superiority of the new method. 相似文献

In this article, we present the effects of three hypothesized protective factors—social activities, school-related activities, and anti–substance use media messages—on adolescent tobacco and alcohol use. Data were drawn from the “Monitoring the Future” research project, which was conducted by the Institute for Social Research at the University of Michigan. The sample included 2,551 twelfth-grade students. The results of the structural equation model showed that exposure to media anti-drug messages had an indirect negative effect on tobacco and alcohol use through school-related activity and social activity. The results suggest that comprehensive ecological interventions encompassing media, family, and school can increase the preventive effects of adolescent's substance use. 相似文献

The MINQUE and its modifications are considered for estimating the variances of the balanced one-way random effects model. The effects of the a priori values on the estimators of the variances are examined in detail. The Mean Square Errors of the estimators are compared for variations in the prior values of the unknown variances. 相似文献

The world economy today is swept by unprecedented rates of change, complexity, interconnectedness, and uncertainty. For the first time since the 1930s, issues of the international economy and financial markets are playing a pivotal role in discussions of foreign and domestic policy. However, even as the revolutionary trends in the international economy and in world finance are in the offing, it is important to realize that the problems of mankind are primarily economic and social, not financial or political. While the trends towards liberalization of economic policies and integration of financial markets might seem to point toward the ultimate triumph of the magic of the market and free enterprise, a little reflection will reveal a number of undercurrents, dilemmas, and difficult choices waiting to be resolved. This article identifies the structural and human dimensions of these challenges in the form of thirteen Policy Imperatives aimed at the creation of modified versions of financial markets to make them more humane and less vulnerable to failure. 相似文献

Iron and steel is a key industry in the Indian economy. The author looks at the prospects into the next century and the options facing the industry over the next two decades. New capacity will have to be undertaken but it will undoubtedly be difficult to fund this without external assistance and without diverting resources from other areas. Thus it will be necessary to plan for technological innovation to achieve production objectives, and such technology must be developed in India, or imported and adapted to suit indigenous conditions. 相似文献

The method of ratio estimation for estimating the population mean ? of a characteristic y when we have auxillary information on a characteristic x highly correlated with y, consists in getting an estimator of the population ratio R = ?/X? and then multiplying this estimator by the known population mean X?. Though efficient, ratio estimators are in general biased and in this article we review some of the unbiased ratio estimators and discuss a method of constructing them. Next we present the Jackknife technique for reducing bias and show how the generalized Jackknife could be interpreted by the same method. 相似文献
