数据论文国内外发展研究综述   总被引:1,自引:0,他引:1  
[目的/意义]数据密集型科学范式增加了科学数据共享的重要性和紧迫性。数据论文作为一种新兴的数据出版模式,成为国内外相关领域研究热点。调研国内外相关文献,希望为我国数据论文与数据期刊实践与研究提供参考与借鉴。[方法/过程]基于国内外文献调研,从数据论文的概念、出版模式、不同主体的态度、当前模式的缺陷及未来发展方向几方面介绍和评述数据论文这一数据出版模式的发展情况。[结果/结论]数据论文为解决数据出版中的归属、激励、质量和引用等问题提供了新思路,近年来受到国内外相关领域和主体的广泛关注。与国外相比,国内在实践和研究中存在一些不足,建议研究中关注国内数据期刊的发展,加大对具体问题的研究深度,实践中借鉴国外经验,结合国内特点,从平台、渠道、政策等多方面完善和推广这一新兴数据出版模式。  相似文献

Language is an important way of presenting an identity, either individual or group. This paper explores the language used in the presentation of the identity of academic development. The study is based on an analysis of websites from academic development centres in the UK and Australia and outlines the public ways in which academic developers present their work and the meanings that are attached to this presentation. It uses frame theory to analyse the language of academic development websites in order to explore some of the assumptions underpinning the public face of academic development. It explores the ways in which language is used to frame and persuade in order to establish the credibility of academic development as an expert and scholarly field.  相似文献

Los autores proponen la Lingüística Textual para un reenfoque de las actividades de análisis de texto en la enseñanza. Como modelo de aplicación de esa propuesta se expone un caso de análisis textual de una nanación en el que se localizan los mecanismos de coherencia y se generan preguntas de control y ejercicios para que el alumno desarrolle estrategias de lectura.  相似文献

The analysis of the Batteries and AIDS episodes presented in this article is guided by the assumption that thinking can be conceptualized as an activity of communication, and learning can be regarded as modifying and extending one's discursive ways. Within this framework, 1 of the aims of mathematical learning is to become skillful in the discursive use of designated symbolic artifacts supposed to mediate solving certain types of problems. My analysis of the learning episodes is aimed at uncovering the ways in which the discursive uses of such new symbolic tools were interactively constructed by the students. I argue that the construction process is extremely complex because of a certain inherent circularity of this process. The analysis reveals that this difficulty may be overcome by the gradual dialectic adjustment of former discursive habits to new contexts. The adjustment happens gradually, through cycles of intimations about the applicability of the old habits followed by implementations in which this applicability is examined. This intricate interplay of intimations and implementations is found in both the Batteries and the AIDS episodes and is presented in detail in the article. I also show that, with time, students significantly increased their mastery of this particular discursive mechanism.  相似文献

ABSTRACT

The aim of this study was to compare the effects of 20 min neuromuscular training with a programme of 10 min in youth football players. 342 (15.4 ± 1.7 years) male football players from 18 teams were included, and cluster-randomized by team into two intervention groups. Both groups performed an injury prevention programme twice a week over five months using the same exercises but a different duration. The first intervention group (INT10, n = 175) performed the programme for 10 min, the second intervention group (INT20, n = 167) for 20 min. Primary outcomes were lower extremity (LE) injuries. Secondary outcomes were injury type, severity, mechanism and compliance to the intervention. 13 teams with 185 players were included for final analysis. No significant group difference was found between INT10 (6.37 per 1000 h) and INT20 (7.20 per 1000 h) for the incidence rate ratio of the lower extremities (IRR = 1.03, 95% confidence interval 0.59, 1.79), nor for the distribution of injury location, type, severity or mechanism. The results show that performing preventive exercises for 10 min is no less effective than 20 min in youth football players. Shorter training sessions can, therefore, be effectively used for injury prevention.  相似文献

Traditional media have been changing in response to digitisation processes and the spread of the internet. This article looks at the consequences of technological change for the organisational structures of publishing houses in Germany, most of which are small to medium sized enterprises (SMEs). Following any decision to produce digital content, new tasks emerge which need to be fulfilled and publishing houses have to re-allocate appropriate responsibilities. The context of the preference for in-house or for external production is explored as is the precise identification of the managerial and technical skills demanded by a switch to digital publishing. The findings suggest the important role of strategic partnerships with service providers as well as with other publishing houses, especially for larger projects beyond the capabilities of SMEs.  相似文献

Filipino parents’ school choice and loyalty: a factor analysis   总被引:1,自引:1,他引:0  
This quantitative study aims to ascertain the significant relationship existing between parents’ profile, and their school choice and school loyalty. Data were gathered using the researcher’s two-part made instrument. Respondents were first asked to fill in a robotfoto for purpose of profiling their baseline characteristics and were later asked to rate listed indicators, using a modified 8-point Likert scale. Using statistical tools such as the ANOVA, factor analysis, correlation, mean, and standard deviation, data were treated indepth. It is interesting to note that although parents are loyal to their alma mater, this does not have a much impact on their choice of school for their children. On the whole, parents’ choice of school is based on its indispensable qualities. Among the three interval-scale profiles of the parent respondents such as age, income, tuition fee payment and number of children, none of these relate to school choice, but age, income, and tuition fee payment negatively relate to school loyalty. From their nominal-scale profiles, significant differences were noted in their school choice when grouped according to civil status, place of work, and terms of payment. With respect to school loyalty, significant differences occurred in their responses when classified according to gender, terms of payment and their active participation in the Parent-Teacher Association (PTA).  相似文献

This article analyses the use of peer and self-assessment in oral presentations as complementary tools to assessment by the professor. The analysis is based on a study conducted at the University of Girona (Spain) in seven different degree subjects and fields of knowledge. We designed and implemented two instruments to measure students’ peer and self-assessment, and a rubric to guide the assessment process. Results were compared with the marks awarded by the professor. In contrast with studies by other authors, which show a high correlation between these different assessment systems, our study revealed significant deviations. Applying peer and self-assessment to oral presentation activities also demonstrates their formative value above and beyond their summative usefulness.  相似文献

Environmental education in schools is an important strategy in achieving environmental improvement. However, it needs to be based on children's understandings of environment rather than on assumptions of what children know and believe. This paper reports on a research project where school children's answers to a question 'I think the term/word environment means ' were analysed using the qualitative research method of phenomenography. Six distinct conceptions were isolated, ranging from the least sophisticated--environment as a place--to the most inclusive and expansive--environment and people in a relationship of mutual sustainability. An important qualitative difference was found between conceptions that treat the environment as an object and relational conceptions. The implications of these findings for environmental education are discussed.  相似文献
