实践与选择：纪念人民代表大会成立60周年

人民代表大会制度是中国人民权益的根本保障。作为第十二届全国人大代表和全国人民代表大会成立60周年庆祝大会的亲历者，作者从人民代表大会制度是中国人民百年探索的珍贵收获和必然选择、人民代表大会制度从根本上保障了中国人民的各项权益、人民代表大会制度是实现中华民族伟大复兴中国梦的根本制度保障三方面阐述了人民代表大会制度的优越性和重要性。     

Percentile Related Bounds and Estimator for the Mean of the Negative Binomial Distribution

Upper and lower bounds are obtained for the mean of the negative binomial distribution. These bounds are simple functions of a percentile determined by the shape parameter. The result is then used to obtain a robust estimate of the mean when the shape parameter is known.     

Period Parity Progression Ratios and Birth Intervals in England and Wales, 1941–1971: A Synthetic Life Table Analysis

A method is presented for analysing maternity history data to provide period estimates of parity progression ratios, birth intervals and related indices. This is applied to a sample of the marriage and maternity histories from the Census of England and Wales of 1971 and shows: (a) a general increase through the 1950s and into the 1960s in period estimates of marriage and parity progression ratios, especially in the progression from first to second birth; (b) a general acceleration of fertility with, again, the second birth interval becoming particularly short and compact; and (c) very steep declines in third and fourth birth progression ratios from the mid-1960s. Birth interval distributions altered during the period examined. Decomposition of a progression-based total fertility index shows change in the ratios for lower birth orders to have dominated the fertility upswing and declines in ratios for higher birth orders to have initiated the subsequent decline.     

Sequential estimation problems for negative exponential populations

The literature on sequential estimation problems for negative exponential populations has been reviewed here, We attempt to bring in all the published and unpublished materials known to us in a fairly coherent fashion. Both the concepts and theoretical findings are discussed.     

公司治理结构与投资决策安排

厂商的投资决策在受体制模式制约的同时,也在很大程度上受制于企业的制度安排.公司治理结构之于投资决策安排,属于市场经济体制模式下的制度与行为之间的微观制约关系.联系宏观经济运行看问题,这种制约关系的格局会影响到经济运行和发展.本文在对两者之相关性作出概要解说的基础上,重点分析公司治理结构对投资决策安排的内在规定性,并以此为基础透视了我国现阶段公司治理结构的基本特征在哪些方面决定着公司的投资决策安排;作为对公司治理问题的一种探讨,文章穿插了对我国特定制度环境下公司治理模式的两种主要类型的讨论,认为不同类型的公司治理模式具有不同的投资决策机理.     

从中国与前苏联政治体制改革比较看中国的成功经验

中国与前苏联两国政治体制改革在起点、切入点、目标与模式等方面有着巨大的差异,并由此带来了两个国家截然不同的发展现状与前景。从两国政治体制改革的比较中,可以总结出中国成功的经验,即在政治体制改革中坚持中国共产党的领导,坚持社会主义的发展方向,坚持稳定压倒一切,坚持从中国国情出发。     

The numerical evaluation of the distribution function of a bilinear from to a quadratic from with econometric examples

This paper considers a general and computationally convenient method of evaluating the distribution function of statistics that are the ratio of a bilinear form to a quadratic form. Numerous Economemc applications of the method are given.     

外来移民与塞浦路斯的民族形成--兼述塞浦路斯历史上希腊族人与土耳其族人的关系

塞浦路斯最早的居民是古塞浦路斯人;后来古希腊移民成为塞浦路斯居民的主体,他们不仅融合了古塞浦路斯人,而且先后同化了移居塞浦路斯的腓尼基人、犹太人、阿拉伯人;惟有移居塞浦路斯的亚美尼亚人和马龙派教徒保持着自己的民族特性;姗姗来迟的土耳其人成为塞浦路斯的第二大民族,并保持着他们的宗教信仰、语言和文化传统。
