Introduction.

This article introduces the current issue of Health Psychology. The call for early intervention to prevent adulthood health problems and the need to consider each period of children's lives within its developmental perspective are the main emphases in this special issue of the journal.

The Structure of Working Memory From 4 to 15 Years of Age.

The structure of working memory and its development across the childhood years were investigated in children 4-15 years of age. The children were given multiple assessments of each component of the A. D. Baddeley and G. Hitch (1974) working memory model. Broadly similar linear functions characterized performance on all measures as a function of age. From 6 years onward, a model consisting of 3 distinct but correlated factors corresponding to the working memory model provided a good fit to the data. The results indicate that the basic modular structure of working memory is present from 6 years of age and possibly earlier, with each component undergoing sizable expansion in functional capacity throughout the early and middle school years to adolescence.

Fetal Neurobehavioral Development: A Tale of Two Cities.

Longitudinal neurobehavioral development was examined in 237 fetuses of low-risk pregnancies from 2 distinct populations-Baltimore, Maryland, and Lima. Peru-at 20. 24. 28. 32, 36. and 38 weeks gestation. Data were based on digitized Doppler-based fetal heart rate (FHR) and fetal movement (FM). In both groups. FHR declined while variability, episodic accelerations, and FM-FHR coupling increased, with discontinuities evident between 28 and 32 weeks gestation. Fetuses in Lima had higher FHR and lower variability, accelerations, and FM-FHR coupling. Declines in trajectories were typically observed 1 month sooner in Lima, which magnified these disparities. Motor activity differences were less consistent. No sex differences in fetal neurobehaviors were detected. It is concluded that population factors can influence the developmental niche of the fetus.

撬装式油井热洗装置研制及应用效果评价

油井热洗是油田最常用的一种清蜡方法。靖安长6油藏是采油三厂的主力油藏,截至2004年底建成油井1064口,由于长6层原油含蜡量高,油井结蜡严重,通常采用常规热洗方法进行油井清蜡。存在以下两方面问题：一是常规油井热洗方法操作比较复杂,运行动力设施多,热洗费用较高；二是常规洗井油源均来自联合站或接转站,为不同层所采的混合原油,进入地层后,会对地层造成一定程度的伤害。为此,我们认真分析了现有油井热洗工艺的不足,查找了油井热洗费用高的影响因素,结合靖安油田长6油藏丰富的伴生气资源,自主研发了撬装式油井热洗装置,经过现场应用取得了较好的效果。

Obituaries: Martin Deutsch (1926-2002).

Reports the death of Martin Deutsch (1926-2002) and notes his contributions to the field of developmental psychology. Deutsch believed that environmental influences were critical for cognitive development during children's early years and that it was possible to design programs that would provide some of those experiences for children.
