Most traditional concepts about creative writers include the idea that creative talent is evident early - that productive and talented writers began their careers at a young age. Yet few empirical studies have actually examined this supposition. A study of 986 creative writers from the twentieth century investigated the relationship between the age at first publication and measures of productivity (numbers of works produced) and success (winning a Nobel or Pulitzer prize). While significant relationships were found between an early debut and increased productivity in poetry and total number of works, it is more noteworthy that a writer's age at first publication was not significantly related to total productivity in fiction or success. Implications for creative writers and teachers of creative writing are discussed, along with how these findings might be incorporated into the current standards-based reform efforts.  相似文献

The need of inspecting a masterpiece of fine art without affecting it led to develop non destructive methods of investigation. In the field of art conservation, several diagnostic techniques are being widely used to inspect works of art, giving different but complementary results. The present work deals with two of these methods, reflectography and thermography, both techniques examining objects in the infrared spectrum but in different wavelength bands. Their integrated data potentially provide a powerful tool for mapping hidden features and alterations of artworks. This was confirmed during the inspections of a 13th century panel painting under restoration at the Opificio delle Pietre Dure laboratories (Florence, Italy). A graphical user interface was also designed to aid operators in the field of conservation dealing with the results of the two IR methods. Many options such as image adjustment, comparison, overlaying and transparency variation, in addition to thermographic elaborations, have been made available to users. Imaging data integration provides a multi-layered and multi-spectral representation of the painting that yields a comprehensive diagnosis confirms the anomalies individuation and reduces the ambiguities of information coming from a single diagnostic method.  相似文献

This article addresses the issue of transition from secondary to post-secondary education through collaborative research with teachers from both levels. It takes into account implicit elements in this transition. Research on the transition in mathematics education tends to focus more on the tertiary level, studying difficulties encountered by students or comparing curricula, tasks, and textbooks highlighting disruptions or cultural shifts. However, according to Hall (1959), and Artigue (2004) in a mathematical context, it is the implicit “ways of doing” that lead to the greatest cultural differences. In this article, attention is paid to the particular ways in which teachers’ ways of doing mathematics impact the transition. Ethnomethodology (Garfinkel, 1967) and its central concept of ethnomethods are used as the theoretical framework to conceptualize these ways of doing mathematics. A breaching situation presented to a group of secondary- and tertiary-level teachers engaged in collaborative research (Desgagné et al., 2001) brings to light familiar ways of doing mathematics. Our analysis focuses specifically on a comparison of the ways of doing mathematics related to functions at each level.  相似文献

The World Health Organization Regional Office for Europe (WHO EURO) and the German Federal Centre for Health Education (BZgA) published the Standards for Sexuality Education in Europe in 2010. The standards were developed to provide an overview of those sexuality education issues that should be addressed in school at various specific age levels. They were intended to guarantee that sexuality education teaching is age-appropriate and of uniformly good quality throughout Europe. In the context of the present survey, Austrian teachers and parents or guardians were asked about the importance of the topics covered by the WHO standards and about any aspects they would like to see for such sexuality education to be successful. The paper concludes that parents and teachers agree on the sexuality education topics they find important for coverage in Austrian primary schools, although teachers find sexuality education in general to be of greater importance than do parents. Teacher’ wishes for sexuality education in practice correlate highly with parents’ ideas of quality. Overall, qualifications and support for work in this field are viewed as essential, with survey respondents perceiving the need for high-quality initial training and continuing education and appropriate frameworks for implementation in school.  相似文献

This paper investigates whether a green kind of design helps firms increase their capabilities for inventing in the environmental domain and whether it does so more than ‘standard’ design. It also investigates whether the effect of ‘green-matching’ between new design and technologies is conditional on firms’ innovative capabilities, as reflected by their R&D expenditure. We address these research questions with respect to the world's top R&D investors, looking at their intellectual property rights at the United States Patent and Trademark Office (USPTO) and proposing an original textual identification of green designs and trademarks. We find that green design increases environmental inventions by top R&D investors, and to a greater extent than non-environmental ones. Standard design also stimulates environmental inventions, but to a lesser extent than green design. The ‘green-matching’ actually helps, but internal innovative capabilities are required to make it effective: a green-tech ‘prize’ emerges from green design, but only once a minimum threshold of R&D expenditure has been reached.  相似文献

Most research focuses on preschoolers’ primary non-parental child care arrangement despite evidence that multiple arrangements are relatively common. Using the nationally-representative Early Childhood Longitudinal Study, Birth Cohort, we compare characteristics and outcomes of families whose 4-year olds attend both home- and center-based child care with those who attend either home- or center-based care exclusively or receive no non-parental care at all. We find that about one fifth of 4-year olds attend both home- and center-based child care. Mothers’ priorities for care (getting their child ready for school, matching their families’ cultural background) and perceptions of good local care options predict their combining home- and center-based care. Preschoolers score higher on reading and math assessments, on average, when they attend centers, alone or in combination with home-based child care, than when they are cared for only in homes, either by their parents or by others. Preschoolers’ average socioemotional outcomes generally do not differ between families who do and who do not combine care types. Implications for research and policy are discussed.  相似文献
