This article considers the role of domestic knowledge capabilities for developing countries and emerging economies, and in particular in the build-up of their national systems of innovation. Using bibliometric methods, we describe the geographic sources of knowledge and the users of Brazilian research in 2005–2009, and analyze the roles of domestic and foreign knowledge bases in it. Our results suggest that increasing reliance on domestic sources of knowledge is a feature of Brazil's improved science and technology capabilities. The ascendancy of Brazil's research informs us about the unfolding re-organization of global research, too, underlining nascent South-South knowledge flows, the prevailing relevance of EU research, and the relative decline of US research for Brazilian knowledge creation. 相似文献

This study investigates how children negotiate social norms with peers. In Study 1, 48 pairs of 3‐ and 5‐year‐olds (N = 96) and in Study 2, 48 pairs of 5‐ and 7‐year‐olds (N = 96) were presented with sorting tasks with conflicting instructions (one child by color, the other by shape) or identical instructions. Three‐year‐olds differed from older children: They were less selective for the contexts in which they enforced norms, and they (as well as the older children to a lesser extent) used grammatical constructions objectifying the norms (“It works like this” rather than “You must do it like this”). These results suggested that children's understanding of social norms becomes more flexible during the preschool years. 相似文献

Explicit Theory of Mind Is Even More Unified Than Previously Assumed: Belief Ascription and Understanding Aspectuality Emerge Together in Development 下载免费PDF全文
Existing evidence suggests that children, when they first pass standard theory‐of‐mind tasks, still fail to understand the essential aspectuality of beliefs and other propositional attitudes: such attitudes refer to objects only under specific aspects. Oedipus, for example, believes Yocaste (his mother) is beautiful, but this does not imply that he believes his mother is beautiful. In three experiments, 3‐ to 6‐year‐olds' (N = 119) understanding of aspectuality was tested with a novel, radically simplified task. In contrast to all previous findings, this task was as difficult as and highly correlated with a standard false belief task. This suggests that a conceptual capacity more unified than previously assumed emerges around ages 4–5, a full‐fledged metarepresentational scheme of propositional attitudes. 相似文献

In 2007 Finland changed ownership rights to inventions from its employees – “the professor's privilege” – to universities. We investigate how this change affected academic patenting using new data on inventors and patenting in Finland for the period 1995–2010. Matched sample panel data regressions using difference-in-differences show that patenting by individuals dropped by at least 29 percent after 2007. Unlike other countries studied, in Finland the reform was known before implementation. Adding the period after announcement to the reform period increases the drop in academic patenting to 46 percent. Our and others’ results call into question whether the European reform of the professor's privilege were good innovation policy. 相似文献

This paper focuses on the international experience with early identification and intervention for children with AD/HD. Much less is known about AD/HD in two- to five-year-old preschool children than is known for older school-aged youngsters. Despite this lack of knowledge, AD/HD is increasingly recognized in this population and stimulant medication increasingly prescribed to treat it. The lack of control of temperamental patterns in preschoolers seems related to later observations of hyperactivity, attention problems and antisocial behaviours in school-aged children. The emergence and continuity of AD/HD-like behaviours is influenced not only by genetic, pre- and perinatal factors, but also by social context factors. All these influences interact with a child's developmental needs in complex ways according to a systemic bio-psychosocial model. The undiagnosed AD/HD child will often be labelled by parents as difficult and the family scapegoat. Because of the age of the children and the variety of ‘normal behaviour’ in this group, interventions should include systemic, environmental and play-centred approaches. 相似文献

ABSTRACTThe Internet has become a pivotal source of information among university students. However, studies routinely show that many students lack digital information literacy skills (i.e. skills needed to find and evaluate information online). In this paper, we report results from an experimental study testing the effect of a workshop for third-year students of a German university. The workshop was designed to teach relevant information literacy skills in a computer lab. Afterwards, students were given academic search tasks and their search behavior was recorded with a tracking device. We find that, compared with the control group, workshop participants significantly increased their use of academic databases and cited more articles from scholarly journals. On the other hand, we find no effect on the relevance of the content students found online. Teaching digital information literacy is essential and feasible, but it is no panacea for increasing the academic quality of students’ work. 相似文献

Abstract In this study, we examined the effects of a pre-acclimatization programme on endurance performance at moderate altitude using a resting intermittent hypoxia protocol. The time-trial performance of 11 cyclists was determined at low altitude (600 m). Athletes were randomly assigned in a double-blind fashion to the hypoxia or the control group. The pre-acclimatization programme consisted of seven sessions each lasting 1 h in normobaric hypoxia (inspired fraction of oxygen of 12.5%, equivalent to approximately 4500 m) for the hypoxia group (n = 6) and in normoxia (inspired fraction of oxygen of 20.9%) for the control group (n = 5). The time-trials were repeated at moderate altitude (1970 m). Mean power output during the time-trial at moderate altitude was decreased in the hypoxia group (?0.26 ± 0.11 W · kg?1) and in the control group (?0.13 ± 0.04 W · kg?1) compared with at low altitude but did not differ between groups (P = 0.13). Our results suggest that the applied protocol of intermittent hypoxia had no positive effect on endurance performance at moderate altitude. Whether different intermittent hypoxia protocols are advantageous remains to be determined. 相似文献

Do financial constraints hold back innovation and growth?: Evidence on the role of public policy 总被引:1,自引:0,他引:1
This paper provides evidence that capital-market imperfections hold back innovation and growth, and that public policy can complement capital markets. We deliver the evidence by studying the effects of government funding on the behavior of SMEs in Finland. By adapting the methodology recently proposed by Rajan and Zingales [Rajan, R.G., Zingales, L., 1998. Financial dependence and growth. American Economic Review 88, pp. 559-587] to firm-level data, we show that government funding disproportionately helps firms from industries that are dependent on external finance. We demonstrate that the result is economically significant and robust to a variety of tests. 相似文献
