The main purpose of our study was to examine whether autonomous training through the use of technologies could be associated with improvements in selective attention, visuospatial short-term memory and visuospatial processing in students with Down Syndrome (DS). In addition, our study aimed to analyse how the improvements in selective attention and visuospatial short-term memory tasks could predict improvements in visuospatial processing. Twenty-six children and adolescents with DS who belong to specialized schools for ID participated in the study. Three different mobile applications, Bubbles (selective attention), Pairs and Learn (visuospatial short-term memory) and Tangram (visuospatial processing) developed by Smile and Learn were used during a three-month period by the students. The results showed significant improvements through training in both, Pairs and Learn and Tangram, whereas there was no significant improvement in Bubbles. The results also showed that Pairs and Learn performance could predict a 36% variance in Tangram one. Cognitive and educational implications of these results are discussed. 相似文献

AbstractThe article discusses general structure and dynamics of the sports science research content as obtained from the analysis of 21998 European College of Sport Science abstracts belonging to 12 science topics. The structural analysis showed intertwined multidisciplinary and unifying tendencies structured along horizontal (scope) and vertical (level) axes. Methodological (instrumental and mode of inquiry) integrative tendencies are dominant. Theoretical integrative tendencies are much less detectable along both horizontal and vertical axes. The dynamic analysis of written abstracts text content over the 19 years reveals the contextualizing and guiding role of thematic skeletons of each sports science topic in forming more detailed contingent research ideas and the role of the latter in stabilizing and procreating the former. This circular causality between both hierarchical levels and functioning on separate characteristic time scales is crucial for understanding how stable research traditions self-maintain and self-procreate through innovative contingencies. The structure of sports science continuously rebuilds itself through use and re-use of contingent research ideas. The thematic skeleton ensures its identity and the contingent conceptual sets its flexibility and adaptability to different research or applicative problems. 相似文献

The need to preserve cultural heritage on paper requires the setting up of methods and treatments that can be applied to original documents. The cellulose main degradation processes are hydrolysis and oxidation. Only the first one has been widely investigated. The Istituto Centrale per la Patologia del Libro (ICPL) focused its attention on oxidation phenomena and studied a particular class of reducing agents, namely the borane-amine complexes. During the investigation it was found that the borane tert-butylamine complex, besides being the most promising reducing agent, was also able to react with carboxylic functions. In the present study 1H and 13C NMR, Pulsed field gradient NMR spectroscopy as well as Raman spectroscopy were used as analytical tools to disclose the mechanism of the interaction between the borane tert-butylamine complex and the carboxylic functions. Given the complexity of the paper/environment interactions and the subsequent degradation phenomena, we worked on simplified models based on small carbohydrate molecules in order to reproduce the behavior of degraded paper after reductive restoration. Modified D-glucose and D-cellobiose were used in this first step in order to set up the analytical methods before approaching more complex systems such as microcrystalline cellulose and paper. Our results give the experimental evidence that borane tert-butylamine complex is also able to neutralize acidic functions. This finding has important perspectives in paper restoration. 相似文献

In this article, the theoretical framework of developmental pedagogy is presented as a tool in studying and developing children’s knowing within the arts. The domains of art focused on are music, poetry and dance/aesthetic movement. Through empirical examples from a large‐scale research project, we illustrate the tools of developmental pedagogy and show how this perspective contributes to our understanding of children’s learning of music, dance and poetry. More specifically, we will analyse: (a) the important role of the teacher in children’s learning within the arts; (b) the importance of conversing when learning the arts; (c) what constitutes the knowledge, what we refer to as ‘learning objects’, to be appropriated within the three domains of art focused on; and (d) how to conceive of progression in children’s knowing within the arts. 相似文献

ABSTRACT During the coming years the need for professionals to work with the nation's elders will increase several fold. This will place a great responsibility on university educational programs to prepare enough qualified future professionals to work in the greatly expanding field of gerontology. Prior research has identified several nonacademic and academic experiences that influence a student's decision to become gerontological professionals. One area that has been omitted from this work concerns focus groups. This article reports on the impact that observing a relatively simple and inexpensive focus group of professional geriatric practitioners can have on field practicum preferences among advanced undergraduate social work students at a large Texas state university. Findings indicate that observing a focus group significantly influences students' practicum preferences for working with elders, thereby setting them on a trajectory for a career in geriatrics. 相似文献

This paper presents results taken from 2008 to 2010 of an ongoing microform use study. The number of titles used is evenly distributed over time with microfilm being the most used format and newspapers accounting for half of all usage. When publications are available electronically, users may still use the microform version. This study illustrates how microform and electronic collections are complementary—electronic materials provide better access but microform is better for preservation. Users prefer electronic materials but will also use microform when there is no online version available or when the online version is not an exact copy of the original. 相似文献
