Stillbirth in Australia 3: Addressing stillbirth inequities in Australia: Steps towards a better future

Persistent disparities in stillbirth risk and care are present in Australia. Eliminating these disparities is possible with a commitment to enhancing and scaling up models of culturally safe maternity care shown to be effective for Aboriginal and Torres Strait Islander women and those of migrant and refugee backgrounds. Campaigns to improve public awareness of stillbirth also play an important role in reducing stillbirth risk and consequences. To achieve reach and impact in communities at risk, messaging needs to be framed around the social and cultural context of women’s lives. Here we describe important initiatives underway within the Stillbirth Centre of Research Excellence to develop a coordinated national approach to stillbirth prevention and care in communities that bear a disproportionate burden of stillbirth.     

中国人口老龄化区域溢出与分布差异的空间计量经济学研究

将空间因素纳入我国人口老龄化问题的研究框架,对各地区人口老龄化的空间分布特征进行概括和探索性空间数据分析,利用空间计量经济学理论方法和空间误差模型,对各要素影响作用的方向和大小进行实证研究,最后得出综合结论和政策建议。除老龄化惯性、人口增长以外,首次对人口老龄化区域溢出机制进行了重点阐述。我国人口老龄化区域溢出作用不仅客观存在,而且影响显著,这一发现从空间维度拓宽了研究视野,为我国人口老龄化问题理论研究和政策制定提供了有益的借鉴。     

Determinants of fertility levels and change among developed countries: 1958–1978

This article provides a multivariate cross-national test of the hypothesis that national population/family planning policies have effected levels, and changes in fertility in developed nations over the past two decades. Variation is assessed in the total fertility rates (TFR) in 1978, and in the change in these rates between 1958 and 1978, among thirty developed countries. Measures include socioeconomic development, divorce, percent in consensual unions, female labor force participation, abortion policy, and level of contraceptive use by married couples and, government population/family planning policy. Seventy percent of the variation in 1978 TFR is related to the percent contracepting, female labor force, and the population/family planning policy measures. These are the only measures with significant direct effects. A longitudinal analysis of 1958 to 1978 change in TFRs is also conducted. This model increases R² to 75%, and the three independent variables remain significant. Implications of these findings for policy makers interested in increasing or decreasing fertility rates are noted.     

Designing two factor experiments for selecting interactions

This paper considers the problem of devising a single stage procedure for selecting the treatment combination associated with the largest interaction in a two-factor rfx× c experiment having independent normally distributed observations with common known variance. The intuitive procedure based on the best linear unbiased estimators of the population interactions is employed. Initially an indifference zone formulation is used; the problem of determining the least favorable configuration is reduced to a nonlinear programming problem with log concave objective function and a convex polytope as feasible region. A solution technique is introduced in the context of an illustrative example. The problem is also considered using a preferred population formulation; this approach requires a strengthened version of the indifference zone probability requirement. It is shown that the same sample size guarantees this requirement as does the earlier one.     

我国农村居民生育意愿转变分析

农村居民生育意愿真正开始转变是在全国推行计划生育以后,目前已发生了极大的转变,主要特征是:以期望生育两个孩子且一男一女为主流意识,还有相当比例自愿只生一个,"多子多福"观念基本没有市场,对孩子质量的追求正在替代对数量的追求。生育意愿转变的标准不应是生育政策,而应以符合可持续发展理念的要求为标准。     

如东县计划生育优质服务“三询”评估制

Optimal estimation of a finite population mean under generalized random permutation models

Employing certain generalized random permutation models and a general class of linear estimators of a finite population mean, it is shown that many of the conventional estimators are “optimal” in the sense of minimum average mean square error. Simple proofs are provided by using a well-known theorem on UMV estimation. The results also cover certain simple response error situations.     

南京市失业人口状况分析

根据"五普"南京市人口10%抽样调查数据,对南京市失业人口状况作了统计分析.分析结果表明,失业人口约占"非在业人口"的1/10略多,其中近2/3为"寻求再就业"人员.人口抽样失业率为6.08%,城区失业率较高,老城区人口失业问题更严重.15～25岁初次寻求就业和40～45岁寻求再就业的群体为两个"就业困难年龄段".女性群体在就业上处于明显弱势,其中25～45岁女性失业比例显著高于男性.但在初次寻找工作中,年轻男性碰到的困难大于年轻女性,而在失业后寻求再就业过程中,女性的困难远高于男性.     

流动人口子女及其教育：概念的辨析

“流动人口子女”这一概念近些年使用非常广泛 ,但它本身却是一个遭到误用、被窄化使用的概念。按照概念准确地说 ,流动人口子女不仅指流入城市的流动儿童 ,也应该包括留在乡村的“留守儿童”。因此 ,讨论“流动人口子女教育”的问题 ,也相应需要从这两个方面的一致之处着眼 ,以从整体和宏观的角度全面看待这个问题 ,把握问题的实质并更好地解决问题。     

基于生存分析的边境地区人口外流及影响研究

本文依据国家计生委2011年对吉林省中朝边境地区人口流动的抽样调查数据,运用非参数及半参数的生存分析模型对外流人口特征、流动影响因素进行研究,同时分析了人口外流对该地区经济及社会发展的影响。实证结果表明：年轻、受过良好教育的个体是外流人口中的主力,且韩国为其主要流入地;民族因素显著的影响个体选择,但性别影响并不显著;最后,尽管外出个体汇款对该地区GDP有一定贡献,但劳动力的严重流失不仅抑制了当地经济长期发展,同时也导致了人口老龄化等社会问题。因此,为了发展地方特色经济,当地政府在为吸引高端人才、招商引资创造条件的同时,还应采取措施避免受过良好教育的劳动力进一步外流,以期促进当地经济持续发展。
