毛泽东与“另起炉灶”的外交战略理论和实践

建国之时,毛泽东和党中央根据当时的国际形势,从中国人民的根本利益出发,提出和实施“另起炉灶”的外交战略,成为新中国在当时最重要的外交方略之一。“另起炉灶”外交战略理论的提出实施,彻底划清了新中国外交与旧中国外交的界限,从根本上维护了“一个中国”的原则,使新中国走上了真正独立自主的道路。因此,“另起炉灶”的外交战略理论不仅具有伟大的历史意义,而且具有伟大的现实意义。     

新时期中国经济现代化成功启动的原因

改革开放以来,中国经济现代化实现了成功启动。其成功启动,离不开对百余年中国现代化史的科学总结,离不开对旧有社会主义发展模式的深刻反思,离不开对旧的国际战略格局的超越,同时也离不开现代西方工业文明的深刻影响。正确总结其原因,对今天的现代化建设仍具有重要意义。     

The source of Black-White inequality in early language acquisition: Evidence from Early Head Start

I compare language learning trajectories for Black and White children over the first 3 years of life using data from the Early Head Start Research and Evaluation study (EHSRE) in order to determine the timing and source of divergence in early language skill. Results indicate that that while controlling for racial differences in family background and a measure of the home language environment cannot entirely account for disparities in language acquisition, interactions between age, race and maternal education, and between race and a time-varying measure of the home language environment play a significant role. I show that returns to parental education and the home language environment, in terms of language learning, are higher for White children than their Black peers. Specification checks confirm that these results are robust to alternate definitions of child language and the home language environment, and that no interactions between race, age and any of the other covariates are significant. I discuss possible explanations for these race specific education gradients, including measurement error and test bias. In addition, I address relevant empirical issues in estimating language growth with respect to linguistic inputs and the home language environment.     

The Importance of Early,Targeted Intervention: The Effect of Family,Maternal, and Child Characteristics on the Use of Physical Discipline

Secondary analysis of Early Head Start Research and Evaluation Study longitudinal data explored family, parent, and child factors that contribute to the use of physical discipline with infants and toddlers. The sample included mothers (N = 1,580) who self reported the use of spanking at 14, 24, and 36 months. Eighteen percent of the mothers (n = 287) indicated that their children experienced consistent physical discipline. Data were analyzed using binary logistic regression. Participation in parenting classes resulted in a 30% reduction in the use of physical discipline. For every year older the mother was at the birth of the child, there was a 7% decrease in physical discipline. Increased knowledge of child development reduced spanking by 35%. Implications for social work practice with families of young children are discussed.     

一首别开生面的山水诗——曾公亮《宿甘露寺僧舍》论析

曾诗描绘宿甘露寺僧舍的情景。一二句写近景,三四句写远景。山水诗或者写景诗,从视觉落笔,几成为诗人们最常用的表现手法。曾公亮此诗却避开这种传统章法,开篇即从感觉、听觉写起,三四句一反常理逆逻辑顺序绘景。起笔既不落窠臼,末二句写法又富创变,全诗于虚处传神,显得别开生面而又饶有新意和诗趣。     

A Storm in a Tea‐Cup? ‘Making a Difference’ in Two Sure Start Children's Centres

Sure Start Children's Centres were central to the last UK Labour government in improving outcomes for children and families. Yet, participation by those who ‘ought’ to attend was and remains a focus of concern. Using the work of Foucault, this paper explores parental participation in two Centres to examine how ‘government operates at a distance’, through the everyday interactions of those who inhabit these spaces. In exploring micro‐practices, the humble cup of tea can be seen, not only as a small act of caring but a site of power and struggle over what these spaces meant to parents and practitioners.

A method for analyzing supersaturated designs inspired by control charts

The identification of active effects in supersaturated designs (SSDs) constitutes a problem of considerable interest to both scientists and engineers. The complicated structure of the design matrix renders the analysis of such designs a complicated issue. Although several methods have been proposed so far, a solution to the problem beyond one or two active factors seems to be inadequate. This article presents a heuristic approach for analyzing SSDs using the cumulative sum control chart (CUSUM) under a sure independence screening approach. Simulations are used to investigate the performance of the method comparing the proposed method with other well-known methods from the literature. The results establish the powerfulness of the proposed methodology.     

The Association between head Start Enrollment and Children's Mental Health Scores

This study examined the association of the children's entry age and enrollment duration of Head Start on children's mental health, using secondary data analysis. Children were of three groups: one group of children entered Head Start at age 3 and maintained enrollment for 1 year (Group 1), the second group of children entered Head Start at age 4 and stayed for 1 year (Group 2) and the third group of children entered at age 3 and stayed in Head Start for 2 years (Group 3). Research questions are (1) Do child and family characteristics have any association with mental health scores? (2) Do children's mental health scores differ among the three groups? Compared with children who entered at age 4 and stayed for 1 year, children who entered Head Start at age 3 and stayed in Head Start both for 1 year and for 2 years had higher mental health scores. Controlling for other factors, boys and children with special needs had higher mental health scores. Black and dual bilingual children had lower mental health scores.
