Journal author rights and self‐archiving: the case of Spanish journals     

R. MELERO  J.M. RODRÍGUEZ‐GAIRÍN  F. ABAD‐GARCÍA  E. ABADAL 《Learned Publishing》2014,27(2):107-120

Open access (OA) literature is digital, online, free of charge, and free of most copyright and licensing restrictions. The lack of clarity of publisher permissions for archiving in OA repositories affects the adoption of the green OA route. This paper explores editorial policies and self‐archiving conditions in 1,615 Spanish scholarly journals. 48% are published by university and research institutions, 25% by associations/societies, and 17% by commercial publishers; social sciences and humanities (SSH) accounted for 67% of the journals (44.5% and 22.5%, respectively) followed by health sciences (20%); 71% offered gratis access immediately after publication, and 11% after an embargo; 31% provided some mention of author rights. Self‐archiving was specifically allowed by 65% of the journals; 52% were classified as ROMEO‐blue, 12% as green and 15% as white, and 21% could not be classified; 21%, mostly in SSH, used some type of Creative Commons license.  相似文献   

The quest for visibility of scientific journals in Latin America     

Catalina ESTRADA‐MEJÍA  Clemente FORERO‐PINEDA 《Learned Publishing》2010,23(3):237-252

This article studies the strategies for visibility of some of the most outstanding publications from Mexico, Venezuela, Brazil, Chile, Argentina, and Colombia, and the relationship between open access and the visibility of these journals. By means of in‐depth interviews with the editors, we explored their indexing and circulation strategies and examined certain organizational and contextual variables that may have helped them to remain in circulation. We also considered whether a combination of electronic publication and open access to the contents of the journals have increased the visibility of science from these developing countries. When these journals were not available electronically, even if they were distributed at no cost, their distribution was necessarily selective, and one could not properly speak of open access; once they were put on the Web, however, they became widely available at no cost to the reader. The editors' views on open access are also explored.  相似文献

Narrative transportability,leisure reading,and genre preference in children 9–13 years old     

Jakob D. Jensen  Katheryn Christy  Melinda Krakow  Kevin John  Nicole Martins 《The Journal of educational research》2016,109(6):666-674

Leisure reading behavior is a key predictor of educational success. Transportability is a trait that determines how likely an individual is to become involved in a story, and past research has suggested that involvement may be related to leisure reading behavior. However, available measures of transportability have not been validated with children or related to leisure reading. To address this gap, children 9–13 years old (N = 136) completed a revised version of the Transportability Scale. A 13-item version of the scale was found to be unidimensional, reliable, and predictive of 6% of the variance in leisure reading (above and beyond sex, age, reading ability, and student performance). Transportability was also related to genre preference and several interesting sex differences emerged. The Transportability Scale provides researchers with a psychometrically sound measure of narrative involvement to advance research on leisure reading.  相似文献   

Intervention for executive functions development in early elementary school children: effects on learning and behaviour,and follow-up maintenance     

Natália Martins Dias  Alessandra Gotuzo Seabra 《教育心理学》2017,37(4):468-486

Executive functions (EF) can be promoted by classroom interventions. Our study investigated whether (a) an intervention conducted by teachers improves EF in children; (b) there are effects on behaviour and academic achievement; and (c) there are stable benefits in a one-year follow-up. Fifty-eight first-graders, divided into experimental (EG = 28) and control (CG = 30) groups, were assessed in EF, reading and arithmetic tests. Parents and teachers answered EF and behaviour functional scales. The intervention was conducted by teachers in the classroom context. EG children showed greater gains in EF and outperformed controls on reading and arithmetic measures. The EG maintained better performance in the one-year follow-up and showed transfer effect for behaviour measures. The EF intervention may be a useful tool for promoting improved adjustment and academic achievement.  相似文献   

Great expectations: a critical perspective on Open Educational Resources in Brazil     

Giselle Martins dos Santos Ferreira  Márcio Silveira Lemgruber 《Learning, Media and Technology》2019,44(3):315-326

ABSTRACT

Nearly two decades have passed since the Open Educational Resources (OER) movement was launched. Its success in Brazil can be illustrated with the establishment of a UNESCO Chair in Open Education in 2014, in one of the country’s most prestigious universities. Crucially, OER were included in the 2014–2024 National Education Plan, a key piece of national educational legislation, as a category of educational technologies framed as tools. Assuming metaphors such as this play a key role in the ways we think, speak and act, this article presents a critical perspective on OER in Brazil. Examining the implications of the main metaphors used to construe OER in local media and academic sources, the text argues that these metaphors reflect hegemonic discourses on educational technology, concealing the non-neutrality of technological artefacts, obscuring issues concerning curriculum and pedagogy, and overlooking actual local needs. The article discusses issues concerning local OER advocacy, positioned in respect to specificities of a context where education, albeit a constitutionally established right, may be poised to undergo radical changes in the near future.  相似文献   

Peer Review in Education: Promoting Collaboration, Written Expression, Critical Thinking, and Professional Responsibility     

Vinícius Medina Kern  Luciana Martins Saraiva  Roberto Carlos dos Santos Pacheco 《Education and Information Technologies》2003,8(1):37-46

This article discusses the application of the peer review process as a pedagogical instrument for the promotion of written expression, collaborative work, critical thinking, and professional responsibility among Informatics and Engineering majors. The approach is introduced with a motivation, followed by a discussion about common principles of current learning paradigms and the peer review process. This work is being conducted in Brazil, where we intend to promote a learning paradigm shift through the application of peer review in education. A framework for this application is outlined, together with an account of results from experiences and a discussion about the skills that this approach exercises, especially with regard to widely accepted curricula and codes of ethics and professional conduct. Further research and development efforts are conjectured.  相似文献   

Effects of an unsupervised pedometer-based physical activity program on daily steps of adults with moderate to severe asthma: a randomized controlled trial     

Cristina Martins Coelho  Maycon Moura Reboredo  Felipe Martins Valle  Carla Malaguti  Larissa Almeida Campos  Lucas Mendes Nascimento 《Journal of sports sciences》2018,36(10):1186-1193

Supervised exercise has shown benefits for subjects with asthma, but little is known about the effectiveness of unsupervised physical activity on this population. We investigated the effects of a 12-week unsupervised pedometer-based physical activity program on daily steps and on clinical and psychological parameters of adults with asthma. Clinically stable adults with moderate to severe asthma were encouraged to take daily 30-minute walks and were randomized to pedometer and control groups. The pedometer group received pedometers and individualized daily step targets. Changes in daily steps (average of steps taken during six consecutive days), six-minute walk test (6MWT), health-related quality of life, asthma control and anxiety and depression levels were assessed 12 weeks after intervention and 24–28 weeks after randomization. Thirty-seven participants were recruited and 30 completed the intervention. At 12 weeks, the groups differed significantly in daily steps (adjusted average difference, 2488 steps; 95% confidence interval [CI], 803 to 4172; p = 0.005) and in the 6MWT (adjusted average difference, 21.9 m; 95% CI, 6.6 to 37.3; p = 0.006). These differences were not significant 24–28 weeks after randomization. The program was effective in increasing daily steps of adults with moderate to severe asthma 12 weeks after intervention.  相似文献   

Influence of hydrodynamics on the growth kinetics of glass-adhering Pseudomonas putida cells through a parallel plate flow chamber     

S. Mbaye  P. Séchet  F. Pignon  J. M. F. Martins 《Biomicrofluidics》2013,7(5)

The objective of this work was to investigate the influence of hydrodynamics on the growth kinetics of surface-adhering Pseudomonas putida cells. The results showed in particular that under non substrate-limiting conditions, the early step of bacterial apparent growth rate is lower than those measured with suspended cells. Contrary to previously cited authors which explain this behavior to the different adhesive properties of the “daughter”-cells (which makes more probable the detachment of these daughter-cells), in our experimental conditions, that explanation does not hold and we show a clear dependence of growth kinetics with flow conditions, due to the formation of boundary layer concentration at low Reynolds number. These results revealed that using Monod law in the modeling of biofilm growth in fixed-biomass processes should be performed with care.  相似文献   

The effect of the surface functionalization and the electrolyte concentration on the electrical conductance of silica nanochannels     

D. C. Martins  V. Chu  J. P. Conde 《Biomicrofluidics》2013,7(3)

It is known that the conductance of nanochannels as a function of electrolyte concentration deviates from a linearly proportional relationship and approaches a value independent of the concentration as the electrolyte concentration is lowered. Most of the proposed models account for this behavior by considering a constant surface charge density and an ideal electrolyte solution. However, at low electrolyte concentrations, the ideal electrolyte approximation is no longer valid because the ions that result from the atmospheric carbon dioxide dissolution in water dominate the ionic concentration. In this paper, arrays of silica nanochannels were electrically characterized via conductance measurements. The conductance at low salt concentrations is modeled by a variable surface charge model that accounts for all ionic species in solution. This model was used to determine the variable surface charge of the bare silica nanochannels as well as of chemically modified nanochannels. The model correctly predicted the variation of the nanochannel conductance observed after silane (aminopropyldimethylethoxysilane) functionalization and single-strand DNA immobilization. Finally, pH modification of bulk KCl solutions was employed as an alternative method of changing the surface charge of silica nanochannels. Surface charge calculated from conductance measurements performed at different bulk pH values confirmed that the surface charge of the silica nanochannel walls is sensitive to the H⁺ concentration.  相似文献
