The Netherlands form a consensus democracy. In such a society the legitimacy of decisions is of great concern to all. An elaborate system of checks and balances tends to exist and the pressure to join an emerging consensus at meetings is both subtle and tremendously powerful. In the Dutch system of higher education and research the manifestations of the consensus ideal are numerous. This paper highlights them where appropriate. It reviews the Dutch research effort in an international perspective and concludes that R&D expenditure in the Netherlands, measured as a proportion of GDP, is declining. Fairly radical changes in science policy orientation since the 1960s are reviewed and the current frameworks for policy formulation, academic foresight and the organisation of support are sketched. After discussing NWO's different funding instruments, the practices of picking the winners are described in some detail. Three different peer review models are then discussed with special attention to their strengths and weaknesses. The paper's final section is focussed on the evaluation practices in force.  相似文献

冷轧纯铝板在不同温度退火后的织构   总被引:1,自引:0,他引:1  
通过对单向冷轧的纯铝板在140℃,200℃,300℃,380℃退火,用X射线衍射物相分析,研究冷轧纯铝板在退火前和各温度退火后的织构,结果表明,在140-300℃的中低温退火后,板中的形变强织构被削弱,产生新的退火织构;在380℃的高温退火后,板中的形变强织构被进一步增强。  相似文献

Whereas emerging technologies, such as touchscreen tablets, are bringing sensorimotor interaction back into mathematics learning activities, existing educational theory is not geared to inform or analyze passages from action to concept. We present case studies of tutor–student behaviors in an embodied-interaction learning environment, the Mathematical Imagery Trainer. Drawing on ecological dynamics—a blend of dynamical-systems theory and ecological psychology—we explain and demonstrate that: (a) students develop sensorimotor schemes as solutions to interaction problems; (b) each scheme is oriented on an attentional anchor—a real or imagined object, area, or other aspect or behavior of the perceptual manifold that emerges to facilitate motor-action coordination; and (c) when symbolic artifacts are introduced into the arena, they may both mediate new affordances for students’ motor-action control and shift their discourse into explicit mathematical re-visualization of the environment. Symbolic artifacts are ontological hybrids evolving from things with which you act to things with which you think. Students engaged in embodied-interaction learning activities are first attracted to symbolic artifacts as prehensible environmental features optimizing their grip on the world, yet in the course of enacting the improved control routines, the artifacts become frames of reference for establishing and articulating quantitative systems known as mathematical reasoning.  相似文献

We investigated Dutch word stress acquisition in 3‐year‐old children at risk of dyslexia (children with at least one parent or older sibling with reading difficulties) and normally developing children, in order to shed light on language acquisition delays in children at risk of dyslexia, as well as to investigate further phonological deficits in dyslexia. The children had to repeat non‐words with stress patterns varying in regularity. Both the at‐risk and control children performed better on imitation of regular stress targets and worse on irregular and prohibited stress patterns. However, the at‐risk children showed more difficulty imitating irregular and prohibited patterns, and had lower percentages phonemes correct than the control group. The results can be interpreted as a delay in word stress acquisition in the at‐risk group. The findings thus point towards a phonological deficit early in language development.  相似文献

Objective: To analyze the association between attitudes of filial responsibility and adult child caregivers’ behaviors in the Southern Region of Brazil.

Methods: Cross-sectional study with 100 child caregivers of older adults. The data were collected through an interview using the protocol of filial responsibility adapted and validated to Brazilian Portuguese. Filial Expectation and Filial Piety scales evaluated the attitudes of filial responsibility. Caring behaviors assessed were: instrumental support, emotional, financial support, and companionship. The variables that presented p< .20 value in the bivariate analysis were inserted into a multivariate Poisson regression model.

Results: Financial and emotional support behaviors were significantly associated with filial piety (p = .050 and p = .001, respectively) and filial expectation (p = .013 and p = .023, respectively). Providing companionship was associated with filial piety (p = .015).

Conclusion: Attitudes of filial responsibility are associated with some but not all caregiving behaviors. Brazilians caring for older parents show more similarities to Chinese than to Canadian caregivers. Furthermore, filial responsibility and caregiving behaviors are strongly affected by Brazilian social and cultural norms. Reasons are discussed.  相似文献

There is, broadly speaking, an agreement within the international science education community that comprehension of the nature of science (NOS) should be a key element in the scientific literacy of citizens. During the last few decades, several didactic approaches have emerged concerning what and how to teach NOS. Also, one of the basic objectives of science education is for students to become familiar with the skills typical of scientific practice; however, there is little reference to their need to also acquire meta-knowledge about scientific practice (i.e., an understanding of the nature of scientific practice). Among other reasons, this may be due to NOS being essentially identified in most of the predominant proposals with the nature of scientific knowledge. But why not plan the teaching of science to be in tune with real scientific practice for students to learn about the nature of scientific practice at the same time as they are learning science? The answer to this question has given rise to a proposal grounded in ten essential pedagogical principles for the teaching and learning of science in secondary school. These are the principle of formulating questions, the principle of creativity and imagination, the principle of experimentation, the principle of procedural diversity, the principle of errors as opportunity, the principle of modeling, the principle of cooperation and teamwork, the principle of argumentation and discussion, the principle of communication, and the principle of evaluation. The purpose of this article is to present the justification and fundaments of these principles.  相似文献

Spelling skills have been identified as one of the major barriers to written text production in young English writers. By contrast oral language skills and text generation have been found to be less influential in the texts produced by beginning writers. To date, our understanding of the role of spelling skills in transparent orthographies is limited. The current study addressed this gap by examining the contribution of spelling, oral language and text generation skills in written text production in Italian beginner writers. Eighty-three children aged 7–8 years participated in the study. Spelling, lexical retrieval, receptive grammar, and written sentence generation and reformulation skills were assessed and children were asked to write a text on a set topic. A factor analysis revealed that the children’s written text production was captured by three factors: productivity, complexity and accuracy. In contrast to results from children learning to write in opaque orthographies, such as English, this study showed that receptive grammar and written sentence generation skills accounted for significant variance in measures of productivity, complexity and accuracy in Italian children’s written text production. Spelling skills contributed to text accuracy and quality and explained more variance than receptive grammar in microstructural accuracy. By contrast, oral grammatical skills explained more variance in text quality than spelling. The current study shows the differential impact of language systems, such as Italian, on written text production. Implications for assessment and instruction are outlined.  相似文献
