The relationship between lifetime health trajectories and socioeconomic attainment in middle age

A large literature demonstrates the direct and indirect influence of health on socioeconomic attainment, and reveals the ways in which health and socioeconomic background simultaneously and dynamically affect opportunities for attainment and mobility. Despite an increasing understanding of the effects of health on social processes, research to date remains limited in its conceptualization and measurement of the temporal dimensions of health, especially in the presence of socioeconomic circumstances that covary with health over time. Guided by life course theory, we use data from the British National Child Development Study, an ongoing panel study of a cohort born in 1958, to examine the association between lifetime health trajectories and socioeconomic attainment in middle age. We apply finite mixture modeling to identify distinct trajectories of health that simultaneously account for timing, duration and stability. Moreover, we employ propensity score weighting models to account for the presence of time-varying socioeconomic factors in estimating the impact of health trajectories. We find that, when poor health is limited to the childhood years, the disadvantage in socioeconomic attainment relative to being continuously healthy is either insignificant or largely explained by time-varying socioeconomic confounders. The socioeconomic impact of continuously deteriorating health over the life course is more persistent, however. Our results suggest that accounting for the timing, duration and stability of poor health throughout both childhood and adulthood is important for understanding how health works to produce social stratification. In addition, the findings highlight the importance of distinguishing between confounding and mediating effects of time-varying socioeconomic circumstances.     

以写促说：提高英语成段表达能力

写作作为一种输出性运用对于其他语言技能的发展具有促进作用。成段表达能力是中高级英语口语训练的重要目标。口语课实行“从写开始,以写促说”的教学模式,可以有效地提高课堂教学效果以及学生英语成段表达的质量,克服长篇发言的心理障碍,培养外语思维能力,加快语言习得的进程。

试析高校院系资料室的隐性功能

信息时代中 ,由于网络在查找资料上的方便与快捷 ,已经对当前高校的院系资料室形成较大的冲击 ,资料室存在的合理性因此受到质疑。然而 ,笔者认为网络可以取代的只是资料室的显性功能 ,而资料室本身所具有的隐性功能则是网络所无法替代的。本文主要以资料室的隐性功能的阐释为出发点 ,认为环境与交往是资料室隐性功能发挥的重要机制 ,进而剖析高校院系资料室隐性功能的具体体现

Estimation of global temperature fields from scattered observations by a spherical-wavelet-based spatially adaptive method

Summary.  The paper considers the problem of estimating the entire temperature field for every location on the globe from scattered surface air temperatures observed by a network of weather-stations. Classical methods such as spherical harmonics and spherical smoothing splines are not efficient in representing data that have inherent multiscale structures. The paper presents an estimation method that can adapt to the multiscale characteristics of the data. The method is based on a spherical wavelet approach that has recently been developed for a multiscale representation and analysis of scattered data. Spatially adaptive estimators are obtained by coupling the spherical wavelets with different thresholding (selective reconstruction) techniques. These estimators are compared for their spatial adaptability and extrapolation performance by using the surface air temperature data.
