《格萨尔》史诗流布格局分析

《格萨尔》是藏族人民集体创作的一部伟大的英雄史诗,历史悠久,结构宏伟,卷帙浩繁,内容丰富,气势磅礴,流传广泛。从分布的格局上看,《格萨尔》的流传有若干个点,四条线和两个面。点连成线即东北线、东南线、南线和西线四条线。线铺成面,即东北线向北在蒙古草原驻足,又向四周辐射,形成以蒙古草原为中心的蒙古族《格萨尔》传播面,东南线、南线和西线铺成以青藏高原为中心的藏族《格萨尔》传播面。

“多元一体格局”理论视阈下和谐民族关系实现途径探讨

本文从＂中华民族多元一体格局＂理论视阈,论述了和谐民族关系的必要性与实现途径,要旨在于说明：古往今来,我国就是统一的多民族国家,构建和谐民族关系,始终是祖国统一、民族团结和国家安全的重要保障,也是增强中华民族凝聚力和当前实现民族复兴大业的关键所在;费孝通先生所提倡的＂中华民族多元一体格局＂理论,不仅是对中华各民族关系之历史与现状的精辟的理论概括和真实写照,而且对于我们正确认识中国国情,做好民族工作,构建社会主义和谐民族关系,亦有着非常重要的理论价值和现实意义。     

电磁导弹的波瓣特性

首次在球坐标系统下研究了电磁导弹有趣的波瓣特性。研究表明:当天线口径、距离一定时,电磁导弹的波瓣随波形参量减小而变窄;当天线口径、波形参量一定时,电磁导弹的波瓣随距离增加而变窄;当波形参量、距离一定时,电磁导弹的波瓣随天线口径增加而变宽;电磁导弹不存在副瓣;电磁导弹的能量在远轴时仍按球面波方式衰减。这些结论有助于理解电磁导弹的实质。     

科学社会主义与现实社会主义

科学社会主义的创立为无产阶级革命夺取政权指明了方向 ,以列宁为代表的布尔什维克党将科学社会主义理论结合俄国的具体国情 ,指导了俄国的革命 ,成功地建立了人类第一个社会主义国家。但因体制的缺陷和其他原因而解体。中国共产党在总结社会主义建设经验、教训的基础上逐步形成了有中国特色的社会主义。文章着重论述了有中国特色的社会主义是成功的社会主义

Causality and interdependence analysis in linear econometric models with an application to fertility

This paper is an applied analysis of the causal structure of linear multi-equational econometric models. Its aim is to identify the kind of relationships linking the endogenous variables of the model, distinguishing between causal links and feedback loops. The investigation is first carried out within a deterministic framework and then moves on to show how the results may change inside a more realistic stochastic context. The causal analysis is then specifically applied to a linear simultaneous equation model explaining fertility rates. The analysis is carried out by means of a specific RATS programming code designed to show the specific nature of the relationships within the model.     

Sequential Pattern Analysis: A Statistical Investigation of Sequence Length and Support

In sequential pattern analysis, the frequency of patterns is evaluated by the support. While computed efficiently from large databases, we show that the support cannot be compared between different databases, since it is influenced by the actual sequence length distribution. Models for this sequence length distribution are surveyed. One of these models, the Good distribution, appears to be sufficiently flexible for practice. It is used to exemplify an approach for adjusting the relative support such that the resulting adjusted support values are better comparable between different databases. We illustrate our findings with texts from the bilingual FinDe corpus.     

On the Use of Semi-folding in Regular Blocked Two-level Factorial Designs

In this article, we consider experimental situations where a blocked regular two-level fractional factorial initial design is used. We investigate the use of the semi-fold technique as a follow-up strategy for de-aliasing effects that are confounded in the initial design as well as an alternative method for constructing blocked fractional factorial designs. A construction method is suggested based on the full foldover technique and sufficient conditions are obtained when the semi-fold yields as many estimable effects as the full foldover.
