Tradition and Change in Vietnamese Family Structure in the Red River Delta

One of the key features of Vietnamese family organization is patrilocality—the preference of married couples to coreside with the husband's parents. With data drawn from a retrospective survey of persons in 1,855 households in the largest province in the Red River Delta in northern Vietnam, we found that more than 75% of married respondents reported having lived with the grooms' family after marriage. The proportion of newly married couples that follow the patrilocal custom appears to have increased in recent decades, although the average duration of coresidence has declined. Some aspects of modernization, especially nonagricultural occupations and later age at marriage, contribute to a lower incidence of intergenerational coresidence, but the underlying cultural preference to live with the grooms' parents immediately after marriage appears to have become stronger in Vietnam. In contrast to some features of traditional family life that conflict with modernity, intergenerational coresidence can be quite functional in modernizing societies.     

The Role of Family Income in the Intergenerational Association of AFDC Receipt

Daughters from low‐income families who did not receive Aid to Families with Dependent Children (AFDC) are compared to daughters from low‐income families who did receive assistance to better account for family income in the intergenerational association of AFDC. The research models the timing of a daughter's first birth and, for those who become mothers, the number of years a daughter receives any AFDC. Women whose families received AFDC during their childhood are more likely to receive AFDC as adults relative to those women whose families did not receive AFDC. Controlling for family income in a more careful and comprehensive way than past research explains part but not all of the effects of childhood AFDC receipt. Among daughters from chronically poor families, however, parental AFDC use is not associated with additional years of AFDC participation. Although the present research cannot confirm or deny a causal role for parental welfare use, the intergenerational transmission of financial resources does explain part of the intergenerational association of welfare use.

Employment and filial relations: Is there a conflict?

Since children, particularly daughters, are among the most important sources of help and support for older Americans, it has been suggested that women's increasing employment will affect filial relations. Empirical evidence on this issue is inconsistent, in part due to the use of nonprobability samples. Few studies have measured effects for men. We attempt to broaden the scope of this question beyond help to the frail elderly by asking whether employment affects filial relations in general. We examine effects of hours employed on telephone contact, visiting, feelings of closeness, filial attitudes, and assistance to biological parents, for an area probability sample of men and women over 40. There are no effects of employment for men or women on contact, closeness, or assistance. For the vast majority of this population sample, contact and assistance involve few hours per week, and thus do not seem to conflict with employment.

代际支持对流动老年人生活满意度的影响：自我效能感和心理弹性的序列中介作用

以654名流动老年人为调查对象,通过问卷调查探讨不同的代际支持水平对流动老年人生活满意度的影响及自我效能感和心理弹性的序列中介作用。结果表明,代际支持、生活满意度、自我效能、心理弹性四因素之间两两显著相关。自我效能感与心理弹性在代际支持与生活满意度之间均有中介效应,中介效应值为0.198和0.078,且两者在代际支持与生活满意度之间具有序列中介效应,中介效应值为0.107。结果提示,代际支持通过自我效能感和心理弹性的链式中介效应,对流动老年人生活满意度产生直接的正向预测作用。     

Intergenerational Mobility Modes and Changes in Social Class in Contemporary China

Using data from three China General Social Surveys, this paper analyzes changes in the basic situation of intergenerational mobility among social classes in China over the past 60 years. General social mobility was found to have increased, but social openness tended to show a wave-like pattern of change. Despite this, intergenerational inheritance was the main form of intergenerational mobility in every period. With the transformation of the socioeconomic system, the main mechanism of social exclusion changed from “systemic exclusion” to “market exclusion,” leading to changes in the structure of social opportunity. As a result, the form taken by intergenerational mobility varied significantly. This is chiefly evident in the gradual decline in the dominance of intergenerational inheritance among particular strata, with cross-class cyclical mobility becoming more difficult. On the one hand, changes in the social exclusion mechanism may increase social openness, making society more dynamic and strengthening social legitimacy. On the other hand, as the dominant class learns how to use market exclusion to achieve class reproduction, class solidification may still be possible in a future Chinese society.     

开放经济下OFDI对产业结构升级效应及传导路径

开放经济下对外直接投资(OFDI)已成为我国融入世界经济的主要途径,在优化产业结构、推进经济转型等方面扮演着重要角色。根据OFDI与产业结构升级及传导路径的互动机理分析,在对安徽省OFDI投资概况和产业结构现状进行分析的基础上,选取2003—2017年相关数据为样本构建VAR模型,运用ADF检验、脉冲响应函数等方法从产业结构总水平角度,实证分析得出短期内安徽省OFDI所能带来的产业结构升级效应并不显著的结论。进而从具体传导路径角度,采用主成分分析法,从10个变量中提取主成分构建VAR模型,运用脉冲响应等方法实证分析得出安徽省OFDI可通过贸易、省内投资、就业和技术路径来促进产业结构升级。为此,安徽省应扩大OFDI规模,提升OFDI质量和效益;增强企业竞争实力和科技创新能力,优化对外投资结构;发挥政府宏观调控和政策引导作用,加大对企业的扶持力度。     

教育主体缺失视角下农村校园欺凌成因及治理

家庭、村庄和学校是农村学生成长过程中的三个重要教育主体，三者相辅相成共同构成农村教育主体结构。农村中小学生正是在该结构中获得成长，而农村校园欺凌事件的频发和多发则与其变化相关。农村教育主体结构的变化包括三个方面：一是家庭教育主体的缺位，表现为农村家庭隔代抚育的“不过问”逻辑；二是村庄教育主体的缺位，表现为村庄交往中的村民相互“不得罪”的逻辑；三是学校主体的缺位，表现为学校管理中官僚主义的“不出事”逻辑。这些主体行为逻辑的变化，进而带来了三者之间良性互动的阻隔，包括家庭与学校勾连的中断、村庄对学生和家庭监管的缺位，以及学校对农村社会的脱嵌。治理农村校园欺凌事件，除了法制和规范进校之外，还要搭建新型的教育主体结构，形成多元化、多主体农村校园欺凌的治理格局。     

现代激进主义文化思潮中的家庭重建——以《女铎》小说中的婚姻家庭观为视角

《女铎》是创刊于1912年,停刊于1951年的一份较有影响的妇女刊物。除了宣扬基督教义,还致力于提高妇女道德及普及新知识。《女铎》发表的小说多展示普通人日常生活中的温馨,所关涉的主题多为呈现于婚姻家庭中舍己的爱,这种爱又多是经历生活的艰难及双方的摩擦后而得的,因而显得愈发可贵。其中的女性常常不是软弱无力或哀怨愁苦,而是具有自尊自立自强的人格、直面人生困境的勇气以及对家庭邻舍的责任等美德。小说呈现出对女性生命价值的尊重,以及个体生命成长与贡献社会之间的平衡意识,揭示出新女性在个人与他者、感情与事业、社会与家庭等方面的调和努力,并本着建设的目的给出解决问题的答案,因而是对现代女性争取恋爱及婚姻自由之后道路的继续探索的体现。较之那些止于冲破旧家庭的新女性的塑造之作,无疑是一种深入;较之很多新文学作品中灰暗失败的新女性生活,也是一种积极的婚姻家庭模式的建造。
