On the first order regression procedure of estimation for incomplete regression models

This article discusses some properties of the first order regression method for imputation of missing values on an explanatory variable in linear regression model and presents an estimation strategy based on hypothesis testing. This work was carried out before Professor V.K. Srivastava passed away in 2001. The author is grateful to the referees for their illuminating comments on an earlier draft of this paper.

Young people leaving care in Scotland

This paper presents the findings from the first national study of young people leaving care in Scotland. The research involved a policy study of all 32 social work departments and a survey of 107 young people from three authorities, 61 of whom were followed up over a six month period. In exploring the implications for policy and practice, it suggests that although the law and national policy context have been strengthened, improving outcomes for young people leaving care will require responses to more enduring problems, as well as the development of more comprehensive local policies.     

Cohabitation, Marriage, and First Birth: The Interrelationship of Family Formation Events in Spain

In this paper, we investigate (1) the mutualcausal relationship between first unionformation and first childbirth, and (2) theexistence of constant unmeasured determinantsshared by these two events. We argue that thesedeterminants mainly consist of valueorientations that are heterogeneous in thepopulation. We apply event-history techniquesto retrospective survey data on Spain, allowingfor unobserved heterogeneity components whichsimultaneously affect the two processes. Ourfindings confirm the existence of a strongselection effect, which influences both unionformation and first birth. When controlling forthese shared factors, we find that the risk ofconception increases immediately at marriage,and it continues to be high during thefollowing four years. Entry into cohabitation,in contrast, produces a much smaller increasein the relative risk of conception. The effectof conception on union formation isparticularly strong during pregnancy, but itdeclines sharply after delivery.     

一种简单随机模型下双重抽样的精度

本文提出了一种估计总体均值的双重抽样方案，第一相样本其指标值是粗估得到的含有误差数据，但调查费用是廉价的，第二相样本采用精确量测方法得到其指标真值，费用较昂，故容量较小，得到的结果表明在调查费用固定下，本文方法优于单一简单随机抽样方案，并对这一方案的具体的使用给出定性分析。     

从论战看20世纪上半叶唯物史观对中国现代学术的影响

20世纪上半叶是中国社会发生巨变和转型的时期。在百花齐放、百家争鸣的思潮激荡之际,思想文化界形成了马克思主义、自由主义、保守主义三足鼎立的格局。就影响而言,三者之中,马克思主义思潮可谓高歌猛进、一枝独秀、独领风骚。其中,唯物史观的影响又是最为显著的,唯物史观作为主要思潮,直接参与和影响了当时思想意识形态领域的六次大规模论战。论战的形式也多种多样,既有温和的学理上的论争,更有针锋相对的激烈的路线立场论战。论战的内容主要围绕唯物还是唯心、经济决定论还是多元论、阶级斗争、群众的历史作用与无产阶级专政等问题展开。经过论战,唯物史观进一步彰显了其学理的科学性和实践的生命力,成为一股重要的理论思潮和行动指南,极大地影响了当时的政治、经济、学术和思想文化,促进了思想文化的现代转化。这种影响不仅体现在一大批马克思主义学者身上,而且更体现在冯友兰、陶希圣这样一些非马克思主义学者身上。可以说,在学理上唯物史观树立起了一面鲜艳的旗帜。
