Many educational theoretical approaches to cosmopolitanism tend towards an unconditional appreciation of mobility, diversity and rootlessness. The recent interest of educational philosophy in the rhizome, de-territorialization and diversity contributes to this understanding of cosmopolitanism as movement across a borderless and imperfect world. Without downplaying such insights (and related political education), this article displaces and de-temporalizes them. It takes the form of a parody of the rhizome to view those insights from a different perspective and make them strike a different pedagogical note. 相似文献

Genotypic and environmental variation in cadmium, chromium, arsenic, nickel, and lead concentrations in rice grains 总被引：1，自引：0，他引：1
Genotypic and environmental variation in Cd, Cr, As, Ni and Pb concentrations of grains, and the relationships between these heavy metals and Fe, Zn were investigated using 9 rice genotypes grown in 6 locations for two successive years. Significant genotypic variation was detected in the five heavy metal concentrations in grains, indicating the possibility to reduce the concentration of these heavy metals in grains through breeding approach. The environmental effect varied with metal, with Pb and Ni having greater variation than the other three metals. There was significant genotype-environment （location） interaction of the concentrations of all five heavy metals in grains, suggesting the importance of cultivar choice in producing rice with low heavy metal concentrations in grains for a given location. Correlation analysis showed that Cd and As, Cr and Ni, and As and Pb concentrations in rice grains were closely associated, and that Ni concentration in grains was negatively correlated with Zn concentration. 相似文献

AbstractFor Kant, we cannot understand how to approach moral education without confronting the radical evil of humanity. But if we start out, as Kant thinks we do, from a morally corrupt state, how can we make moral progress? In response, I explore in this paper Kant’s gradualist and revolutionary accounts of moral progress. These differing accounts of progress raise two key questions in the literature: are these accounts compatible and which type of progress comes first? Against other views in the literature, I argue that gradual progress through a change of mores must come first and can gradually lead toward, as its ideal endpoint, a revolution in our disposition (or a change of heart) and the overthrowing of our radical evil. This has important implications for moral pedagogy. 相似文献

The Consultation Models Revisited series of articles appearing in volume 6 are a testament to the historical strength of consultation approaches and the continuing innovation illustrated by consultation researchers and practitioners. This discussion article highlights the challenges still apparent in developing consultation strategies that are part of a comprehensive plan of services to children. Preventive work is emphasized along with interventions that are aimed at societal issues such as poverty and racism. 相似文献

Simple, reliable and sensitive analytical methods to determine anticariogenic agents, preservatives, and artificial sweeteners contained in commercial gargles are necessary for evaluating their effectiveness, safety, and quality. An ion chromatography (IC) method has been described to analyze simultaneously eight anions including fluoride, chloride, sulfate, phosphate,monofluorophosphate, glycerophosphate (anticariogenic agents), sorbate (a preservative), and saccharin (an artificial sweetener)in gargles. In this IC system, we applied a mobile phased gradient elution with KOH, separation by IonPac AS18 columns, and suppressed conductivity detection. Optimized analytical conditions were further evaluated for accuracy. The relative standard deviations (RSDs) of the inter-day's retention time and peak area of all species were less than 0.938% and 8.731%, respectively,while RSDs of 5-day retention time and peak area were less than 1.265% and 8.934%, respectively. The correlation coefficients for targeted analytes ranged from 0.999 7 to 1.000 0. The spiked recoveries for the anions were 90%～102.5%. We concluded that the method can be applied for comprehensive evaluation of commercial gargles. 相似文献

Knowledge, Concepts, and Inferences in Childhood 总被引：1，自引：0，他引：1
The role of knowledge in children's inferences was investigated in 3 experiments. Experiment 1 examined developmental changes in the role of categorical membership, perceptual appearance, and item complexity in inferences for natural kind and artifact concepts. Preschoolers (5-year-olds), second graders (8-year-olds), and fourth graders (10-year-olds) were taught novel properties about target concepts and asked whether each of 4 probes had those properties. Probes varied in category membership and perceptual appearance relative to the target item. Item complexity also varied. Experiments 2 and 3 examined inferences with known and unknown concepts for familiar and unfamiliar properties. Older children's knowledge led to differential weighting of categorical information over appearance but only for known concepts and/or familiar properties. Preschoolers made no distinction between category and appearance for either known or unknown concepts. Additionally, as target item complexity increased, older children made more inferences than preschoolers. No differences between inferences about natural kind and artifact concepts were found. The role of theories and knowledge in children's drawing of inferences is discussed. 相似文献

In this column, the author explores current understandings of risk and safety in pregnancy and childbirth. An emphasis on risk management places the provider and hospital in control of women’s decisions related to pregnancy and birth and may make pregnancy and birth less safe for mothers and babies. Accepting that no life is risk free, women can let go of fear and make choices that take into account real, not imagined, or exaggerated risk and, in doing so, increase safety for themselves and their babies. The focus of maternity care becomes enhancing safety through evidence-based practice rather than managing risk. 相似文献

Engineering competences form a potential basis for entrepreneurship. There are pressures to find new approaches to entrepreneurship education (EE) in engineering education, as the traditional analytical logic of engineering does not match the modern view of entrepreneurship. Since the previous models do not give tangible enough tools on how to organise EE in practice, this article aims to develop a new framework for EE at the university level. We approach this aim by analysing existing scientific literature complemented by long-term practical observations, enabling a fruitful interplay between theory and practice. The developed framework recommends aspects in EE to be emphasised during each year of the study process. Action-based learning methods are highlighted in the beginning of studies to support students’ personal growth. Explicit business knowledge is to be gradually increased only when professional, field-specific knowledge has been adequately accumulated. 相似文献

Teacher Education in Italy, Germany, England, Sweden and Finland 总被引：3，自引：0，他引：3
GIORGIO OSTINELLI 《European Journal of Education》2009,44(2):291-308
This article presents a brief analysis of teacher education in five European countries: Italy, Germany, England, Sweden and Finland. In the post-industrial world, the sense of teaching has profoundly changed, influenced by a rapidly evolving socio-economic context.
The responses given by each country are different, but two tendencies emerge: on the one hand, the English model, which seeks to make a teacher a faithful executor with regard to centrally decided learning objectives; on the other, the Nordic model that conceives the teacher as a 'fully-fledged' professional.
From the point of view of the sustainability and of the safeguard of the educative mission of the school, the second model, though with all the difficulties that its efficacious realisation entails, presents some advantages when compared to the first. The article concludes with some considerations on the need to conceive the reform of teacher education from a systemic point of view, in the context of a global change of national school systems, where the autonomy of the single schools plays a role of paramount importance. 相似文献
