Labor Force Transitions after Childbirth Among Five Birth Cohorts in Sweden

This article describes part-time work in Sweden and performs a multivariate analysis of the choice between part-time work, full-time work, and other activities in connection with childbirth among five birth cohorts of women. Results show that the combination of market work and family is common, but heterogeneity exists among women in the sample analyzed. Previous labor force participation proves important when it comes to returning to the labor market. The extent of previous labor force participation is also important, regardless of sector of, when it comes to the return to part-time or full-time work. Career orientation and social background also prove significant, some indicators probably working indirectly through higher education and different preferences.     

A Model of Parental Demand for Child Labor with High Fertility Norms

This paper sets out a model to examine how social norms regarding fertility influence parental choice between child labor and child's education. The parent is modeled as a social animal who derives utility from conformity with behavior of other members of the society. In deciding on the number of children, parents internalize the gain of utility from conformity to the norm for fertility. The model investigates the influence of the social element of conformity on the education decision for children and the prevalence of child labor. Social utility from conformity with exogenous social norms of high fertility increases the prevalence of child labor. This social norm can decrease the effectiveness of public policy aimed at encouraging education in place of child labor.     

The demography of words: The global decline in non-numeric fertility preferences, 1993–2011

This paper examines the decline in non-numeric responses to questions about fertility preferences among women in the developing world. These types of response—such as ‘don’t know’ or ‘it’s up to God’—have often been interpreted through the lens of fertility transition theory as an indication that reproduction has not yet entered women’s ‘calculus of conscious choice’. However, this has yet to be investigated cross-nationally and over time. Using 19?years of data from 32 countries, we find that non-numeric fertility preferences decline most substantially in the early stages of a country’s fertility transition. Using country-specific and multilevel models, we explore the individual- and contextual-level characteristics associated with women’s likelihood of providing a non-numeric response to questions about their fertility preferences. Non-numeric fertility preferences are influenced by a host of social factors, with educational attainment and knowledge of contraception being the most robust and consistent predictors.     

移民的文化适应：宁夏吊庄移民的生育观念调适

以扶贫与保护生态环境为重要出发点的宁夏吊庄移民规划,使居住在宁夏西海固地区的大量回族群众搬迁到了宁夏北部易于得到黄河灌溉的地区。伴随着这样的移民搬迁,回族群众的思想观念必然发生变迁。在移民的各种思想观念中,生育观念的转变体现得最为直接与明显。因此,移民群众在生育观念方面的调适就显得极为重要。移民迁出地的历史传统、文化习俗以及迁入地的社会观念、价值标准．都深刻地影响着移民的生育观念。在这些因素中,迁入地城市文化的影响则是一个极为重要的因素。     

Child Care and Child Births: The Role of Grandparents in the Netherlands

This study explored the involvement of grandparents in the care for young children and its effect on subsequent child births in dual‐earner families, using data on 898 Dutch men and women aged 18–49 from the Netherlands' Kinship Panel Study. Three theoretical perspectives were used to develop hypotheses: (a) needs and opportunities, (b) normative preferences, and (c) gendered involvement of grandparents. The findings showed that needs and opportunities informed involvement of grandparents but that the availability of formal child care did not predict grandparents' involvement. Maternal grandparents were more likely to provide child care than paternal grandparents, and grandmothers were more likely to do so than grandfathers. Involvement of both maternal and paternal grandparents in turn increased the likelihood of additional child births. The authors conclude that grandparental child care may be part of an emerging reproductive strategy. Implications of these findings for the theoretical approaches used are discussed.     

Age at first marriage in Malawi: a Bayesian multilevel analysis using a discrete time-to-event model

Summary.  The paper presents a hierarchical discrete time survival model for the analysis of the 2000 Malawi Demographic and Health Survey data to assess the determinants of transition to marriage among women in Malawi. The model explicitly accounts for the unobserved heterogeneity by using family and community random effects with cross-level correlation structure. A nonparametric technique is used to model the base-line discrete hazard dynamically. Parameters of the model are computed by using a Markov chain Monte Carlo algorithm. The results show that rising age at marriage is a combination of birth cohort and education effects, depends considerably on the family and to some extent on the community in which a woman resides and the correlation between family and community random effects is negative. These results confirm a downward trend in teenage marriage and that raising women's education levels in sub-Saharan Africa has the beneficial effect of increasing age at marriage, and by implication reducing total fertility rates. The negative correlation between family and community random effects has policy implications in that targeting communities with an intervention to increase age at first marriage may not necessarily yield reduced fertility levels in individual families. A campaign that is geared towards individual families would achieve the desired goals. Overall, the findings point to the need for the Government in Malawi to enact public policies which are geared at vastly improving women's education at higher levels. The variation in marriage rates over families poses problems in delivering the policy, since particular policies must be devised for specific groups of families to accomplish the required social and health objectives.     

The gendered division of labor and family outcomes in germany

The literature on the predictors of the division of household labor continues to expand, but the effect of this division on family outcomes has not been explored. Using the German SocioEconomic Panel (N= 628), I analyze the effect of men's participation in housework and child care on the likelihood of second birth and divorce. Fathers' greater relative child‐care time increases couples' odds of second birth, attenuating the negative effect of mothers' employment. Husbands' relative housework time is insignificant in predicting second birth or divorce among couples with at least one child, but increases the likelihood of divorce among childless couples. This is evidence that the division of domestic labor affects family outcomes, but effects differ depending on the outcome and presence of children.     

中国人口迁移与生育率关系研究

本文利用2000年人口普查数据,考察了中国人口迁移与生育率的关系。通过比较农村本地人口、城市本地人口和流动迁移人口三个人口群体在生育率上的差异,并进行多元统计分析,结果表明,流动迁移对生育率有着非常显著影响,城市外来人口的生育率不仅显著低于农村本地人口,而且也低于城市本地人口;远期流迁人口的生育率要低于近期流迁人口的生育率。中国人口迁移与生育率的关系出现了与已有的迁移生育率理论的不一致。1990年代中国的迁移生育率发生了转变。     

对消费率的深层思考

2004年国民经济保持平稳较快发展,2004年学术界对消费率空前关注。文章提出政府应当依法办好基础教育,把有限的财政资金向基础教育倾斜;建立和完善以医疗、失业、养老为主的社会保障体系;切实支持“三农”。这些公共管理和服务职能对政府而言责无旁贷。如果造就了一个较好的制度框架和消费环境,有效改善了居民的收人预期和支出预期,消费需求与经济发展自然可以实现良性循环。这正是文章的主旨:提高消费率,功夫在诗外。     

光周期诱导对两系杂交稻育性的影响

以5个两系杂交稻及相应的两用系为材料，在自然温度条件下进行长日（15：00小时）和短日（10：00小时）处理，结果再次表明，两用核不育系的不育性属隐性核遗传，在杂种F1代不表达。两用系的可恢性及父本的恢复力、亲和力是影响两系杂交稻结实率的主要因素。
