不像以前的IETF会议那样,IETF第69次全体会议并不是以技术演示为特色.Olaf Kolkman解释说,很难找到既有趣又与整个IETF团体都很相关的演讲者和话题.后来的开放MAC讨论上提出了一些建议,包括互联网研究任务组(IRTF)主席Aaron Falk提出的应该包含进更多的研究议题,这样可能会鼓励更多的研究者参与到IETF的工作中来.另一位参会者提出,应将IETF的工作组(WG)或IRTF的研究组(RG)的工作展现给更广泛的受众,例如IETF大会的参与者. 相似文献

OBJECTIVE: The purpose of this study was to investigate retrospectively neonatal health and maternal background among a sample of children taken into custody and placed in foster care and to investigate the relation between medical and social risk in the neonatal period. METHOD: The data-linkage study combined two registries: the Finnish Medical Birth Registry (MBR), from January 1, 1987 to December 31, 1989, and the Finnish Child Welfare Registry (CWR) from January 1, 1987 to December 31, 1997 using personal identification numbers (n=1,668). As controls all Finnish children born in 1987 were chosen (n=59,727). Infant neonatal health was estimated using the following indicators: birth-weight and birth-length, birth-weight by gestational age, 1-minute Apgar scores, and discharge age from the nursery. Maternal background characteristics included maternal age, parity, marital status, number of antenatal visits at maternity clinics and smoking during pregnancy. RESULTS: We found that the 1,668 children in the study had a lower birth-weight and birth-length, shorter gestational age, lower 1-minute Apgar scores and later discharge from the nursery than the population-based controls. The proportion of teen-age mothers was about four times higher and the proportion of unmarried women was twice as high. A majority of the women (56%) reported smoking during pregnancy, compared with only 15% of the population-based comparisons. Children subsequently taken into custody had poorer health at the time of birth than other children and these differences could only partly be explained by the differences in smoking habits during pregnancy. The women in the study made use of the free health controls at maternity clinics as much as the population-based comparisons. CONCLUSIONS: Our findings indicate that social and medical risks are related in the neonatal period. Since almost all mothers visit maternity clinics, there are possibilities for early intervention. 相似文献

Although promoting student interest is a pivotal educational goal, student interest in science, and particularly in physics, declines substantially during secondary school. This study focused on the long-term development of interest in physics at the lower secondary level (grades 5–7) and examined the role of teaching and teaching quality on the development. In particular, the study investigated the role of whether or not physics was taught in class and the role of perceived teaching quality for classes' interest trajectories. The results provide evidence of declining interest in physics from Grade 5 to 7, with stronger declines from Grade 5 to 6. Whether classes participated in physics teaching or not neither notably reduced nor increased interest in physics. However, several dimensions of perceived teaching quality (in particular, cognitive activation and cognitive support) mitigated the decline in interest. 相似文献
