A double-blind randomized controlled trial of n-3 long-chain polyunsaturated fatty acid (n-3 LCPUFA) supplementation or matching placebo during third trimester of pregnancy was conducted within the COPSAC2010 mother-child cohort consisting of 736 women and their children. The objective was to determine if maternal n-3 LCPUFA pregnancy supplementation affects offspring neurodevelopment until 6 years. Neurodevelopment was evaluated in 654 children assessing age of motor milestone achievement, language development, cognitive development, general neurodevelopment, and emotional and behavioral problems. Maternal n-3 LCPUFA supplementation during pregnancy improved early language development and reduced the impact of emotional and behavioral problems. The n-3 LCPUFA supplementation was in boys associated with the earlier achievement of gross motor milestones, improved cognitive development, and a reduced impact of emotional and behavioral problems.  相似文献

This paper presents an example of the use of patent statistics as a technology indicator in one industry. The first part deals with the problem of interpretation. Through examination of several other partial technology indicators, it is concluded that at least in this industry, patent statistics provide a reliable indicator, not only for the timing of inventions, but for the timing of innovations and diffusion as well. The reason is that the intervals between the stages in the innovation process are very short. This contradicts evidence from many other industries, and it is therefore emphasized that generalizations are unwarranted.The second part of this paper deals with the possible causes of technological change in Norwegian whaling. The methodology is inspired by J. Schmookler's work. Thus, the patents are correlated with other indicators of economic development in the industry. But while Schmookler's view is that the patent activity is determined by social demand and economic growth, the conclusions for the Norwegian whaling industry point in the opposite direction: the technological transformation that took place during the 1920s and early 1930s was forced upon the firms in their efforts to cut costs, which was achieved by rationalizing production and catching methods in line with a downward price trend for whale oil.  相似文献

Research-based spin-offs (RBSOs) have become an important aspect of the technology transfer process. Emanating from what is conventionally a non-commercial environment, RBSOs pose major challenges if they are to realise their potential to meet the objectives of their founders and the parent research organisations (PROs) from which they emerge. An important issue is to understand the heterogeneity of RBSOs. This paper reviews the literature on RBSO typologies to develop a taxonomy of RBSOs. We identify common themes in relation to these typologies in relation to (1) spin-off creation and (2) spin-off development. The dimensions that differentiate between firms are the type of resources, the business model and the institutional link. We identify gaps in current typologies in order to propose avenues for future conceptual and empirical research.  相似文献

残缺的美     
陈琛 《海外英语》2003,(8):24-26
镜子被打碎了。我将它砸成碎片。它已经毫无用处,镜中的影像残缺不全。我厌恶我所见到的这一切,于是我必须毁灭它。由于对我们所见到的不满,我们挨饿、赎罪、沉沦、甚至自残我们的身体;由于对自身的平庸不满,我们责备惩罚我们自己。  相似文献

Preschool children's social interactions with teachers and peers were observed in the context of moral and prudential events. Twenty groups of children were observed during free play for a total of 164 hours (8 hours per each group). Four types of moral transgressions were observed: physical harm, psychological harm, property loss, and property damage. The majority of the moral transgressions pertained to physical harm and property loss. There were equal frequencies of both moral and prudential physical harm acts; Moral physical harm acts resulted in actual harm; whereas, prudential acts were only potentially harmful. Teachers responded differently to moral and prudential rule violations. Gender differences were noted with regard to instigator, victim teachers' responses, and victims' responses.  相似文献
