Metrics on open access (OA) availability of content published in scholarly journals (i.e. content licences, copyright ownership, and publisher‐stipulated self‐archiving permissions) are still scarce. This study implements the four core variables of the recently published Open Access Spectrum (OAS) (reader rights, reuse rights, copyright, and author posting rights) to measure the level of openness in all 1,728 Spanish scholarly journals listed in the Spanish national DULCINEA database at the end of 2015. Data exported from the database and used as variables for the analysis were: journal research area, type of publisher, type of access, self‐archiving and reuse policy, and type of Creative Commons (CC) licence used. Out of the total number of journals (1,728), 1,285 (74.5%) published their articles OA immediately after initial publication and thus received the maximum OAS score for reader rights; 37.5% of all journals used CC licences, and 79.5% allowed self‐archiving in some form. In 72% of journals, authors retained or publishers granted broad rights, which included author reuse and authorization rights (for others to reuse), whilst 13.5% did not specify any terms for copyright transfer. Similar studies could be carried out on other countries as this would enable comparisons of the general adoption and form of openness in different parts of the world. 相似文献

We propose the use of ISI-JCR categories as units of cocitation and measurement for the construction of heliocentric maps. The use of a spatial metaphor allows us to illustrate, analyze and compare domains in terms of the categories and their interconnections or links. We can also move around within the structure of these domains for further analysis, and access the documents associated to the categories and to the links that cocite or relate them. 相似文献

The aim of this paper is to provide an introduction to higher mathematical concepts and techniques as applied to real-world problems. An interesting case study is the 200-mile limit for fisheries presented in Wan (1989, Mathematical Models and their Analysis (New York: Harper and Row)). It is commented upon, re-examined and solved in a different manner inspired by Turing's (1952, Philosophical Transactions of the Royal Society London , B237 , 37-72) paper as a suitable classroom example for undergraduate students taking a first course on mathematical modelling. Emphasis is made not only on the mathematics--always kept as elementary as possible--but also on interpretations, explanations and translation into plain language of the mathematical expressions and results. 相似文献

The aim of our study is to improve the understanding of the different behavioral intentions of referees and assistant referees in different FIFA (International Federation of Association Football) confederations towards Multimedia Teaching Materials as learning tools. To achieve this goal, we carry out a survey of 214 elite referees and assistant referees and we propose a research model with the variables perceived usefulness, perceived ease of use, perceived enjoyment, perceived self-efficacy, multimedia instruction, previous experience with technology and self-paced learning. These variables were taken from previous educational technology research. Among these models we mainly take into account the Technology Acceptance Model, the Motivational Model and the Social Cognitive Theory. To assess the relationships between the constructs, we develop an analysis based on a Structural Equation Modeling (SEM), specifically Partial Least Squares (PLS). The results of this study confirm that referees and assistant referees are willing to use Multimedia Teaching Materials to assist them in their learning activities as long as they perceive the materials to be useful, enjoyable and easy to use and whenever the course contents are multimedia. 相似文献

This study seeks to develop and validate an Assessment Centre (AC) tool for the evaluation and selection of school leaders, focusing on the identification of competencies that influence teaching and learning outcomes. International research supports the creation of Assessment Centres to select candidates for these roles, due to their superior predictive capacity over traditional methods. In this research, a model composed of four face-to-face instruments (an interview to assess competencies, a human resources exercise, a class observation exercise, and a strategic analysis exercise) was designed and validated which simulated the key tasks of a school principal. To establish the desired performance outcomes, three competencies and 15 indicators were selected, based on international and local standards. The analysis of performance results was obtained from a sample of 164 participants made up of teachers, school leaders and principals. The results suggest positive evidence for construct validity, concurrent criteria validity, and reliability between evaluators. Moreover, the data obtained from a sub-sample of principals, with three or more years of experience in their role, allowed for the association of their AC scores with the results of their school organisations, as measured by the National System for the Measurement of Educational Quality in the years 2013 and 2016. 相似文献

Are children competent producing anatomy cross-sections? To answer this question, we carried out a case study research aimed at testing graphic production skills in anatomy of nutrition. The graphics produced by 118 children in the final year of primary education were analysed. The children had to draw a diagram of a human cross section, integrating knowledge of anatomy acquired from longitudinal sections. The results show that they have very limited skills in producing these graphics judging by the dimensions (scale, shape, organs represented and its organization inside the section) and their conception of human anatomy at thoracic level (location of the organs, elements in the spaces between them and connections between organs). The results also indicate that the only exposure to cross-sections in daily life is not enough by itself to draw them correctly, so this type of graphic production should be addressed from the earliest stages of education, since it contributes to the development of visual literacy, and this is a crucial skill when it comes to learning science concepts and developing scientific literacy. 相似文献

Positive emotional expressivity has been associated with increased social competence and decreased maladjustment in childhood. However, a few researchers have found null or even positive associations between positive emotional expressivity and maladjustment, which suggests that there may be nuanced associations of positive expressivity, perhaps as a function of the social context in which it is expressed. We examined whether observed positive emotional expressivity balance across peer-oriented/recreational and learning contexts predicted kindergarten children’s adjustment (N = 301). Research Findings: Higher positive expressivity during lunch/recess compared to positive expressivity in the classroom was associated with lower teacher–student conflict, externalizing behaviors, and depressive symptoms. In addition, overall positive emotional expressivity predicted lower externalizing behaviors as well as lower depressive and anxiety symptoms. Practice or Policy: The results suggest the importance of assessing observed positive emotional expressivity in context as a potential indicator of children’s maladjustment risk and the need for children to adapt their emotions to different contexts. Implications for assessing and supporting positive emotional expression balance and training emotional regulation in school are discussed. 相似文献

Research Findings: This study explored the relations between Spanish–English dual language learner (DLL) children’s home language and literacy experiences and their expressive vocabulary and oral comprehension abilities in Spanish and in English. Data from Spanish–English mothers of 93 preschool-age Head Start children who resided in central Pennsylvania were analyzed. Children completed the Picture Vocabulary and Oral Comprehension subtests of the Batería III Woodcock–Muñoz and the Woodcock–Johnson III Tests of Achievement. Results revealed that the language spoken by mothers and children and the frequency of mother–child reading at home influenced children’s Spanish language abilities. In addition, the frequency with which children told a story was positively related to children’s performance on English oral language measures. Practice or Policy: The findings suggest that language and literacy experiences at home have a differential impact on DLLs’ language abilities in their 2 languages. Specific components of the home environment that benefit and support DLL children’s language abilities are discussed. 相似文献
