18This article gives an overview of the history and current status of the Directory of Open Access Journals (DOAJ). After a brief historical overview, DOAJ policies regarding open access, intellectual property rights and questionable publishers are explained in detail. The larger part of this article is a much 23 requested explanation on how DOAJ uses its new set of criteria for the evaluation of open access journals and the rationale behind choosing the seven extra criteria that qualify for the DOAJ Seal. A final section is devoted to the extended possibilities that DOAJ will be offering shortly to scholars and 28 publishers for searching the database and for uploading metadata. The result is a renewed DOAJ that offers a more robust platform, a more stable database and enhanced services to allow the upload and collection of metadata.
Over the last five years, scholarly publishing has turned its attention towards metadata; increasingly recognizing it as a strategic priority for digital development. In a 2017 Imbue Partners study based on interviews with industry leaders, metadata was identified as of the highest importance in digital transformation. With an understanding that metadata improvements can be most efficiently made in collaboration, scholarly communications communities are now convening to find ways to jointly improve metadata.Metadata 2020 is a project-driven collaboration of over 120 individuals across scholarly communications, convening to find ways to improve metadata that is connected, reusable, and open for all research outputs. Having launched in September 2017, the collaboration now includes 5 community groups and 6 projects.We include publishers, librarians, service providers, data publishers and repositories, researchers and funders in our work to advance metadata for scholarly communications, to ensure consideration of all stakeholder needs in scholarly communications.In this presentation, we will outline some of the key observations of our community groups around the metadata challenges they face; and explain how these observations evolved into the formation of our 6 cross-community projects. The projects that we will briefly outline include:Researcher CommunicationsMetadata Recommendations and Element MappingsDefining the Terms We Use About MetadataIncentives for Improving Metadata QualityShared Best Practice and PrinciplesMetadata Evaluation and GuidanceGiving a brief overview of the remit and progress to date of each project, we will invite participation from attendees, and provide information about when key resources and guidance will be made available to the communities we serve.
The Directory of Open Access Journals (DOAJ) was founded by Lars Bjørnshauge in 2003; the current managing director is Joanna Ball. A cornerstone in the global Open Science landscape, DOAJ currently lists more than 18,000 peer-reviewed, strictly open access journals (Gold or Diamond). Dominic Mitchell, who has worked for DOAJ for the last ten years, explains how the indexing process is managed by a combination of volunteers and salaried staff like himself, how they work to exclude predatory journals from the list, and how DOAJ is financed. Furthermore, DOAJ is involved in several collaborative projects promoting high-quality scholarly publishing, including The Principles of Transparency and Best Practice in Scholarly Publishing (4th ed., 2022). Recording made during the 17th Munin Conference on Scholarly Publishing. First published online: December 30, 2022.
RESUMO -O conhecimento da estrutura interna de meios porosos muitas vezes permite que modelos matemáticos possam ser simplificados e os resultados obtidos possam ainda ser concisos. O presente trabalho teve como objetivo verificar a concisão da perda de carga obtida comparando um meio poroso de estrutura definida e um meio poroso pseudo-homogêneo. Através das simulações realizadas, pôde-se verificar que a aproximação de um meio poroso psseudo-homogêneo e um meio poroso de estrutura definida é adequado o suficiente tendo um erro normalizado associado médio de 4,02%. Desta forma, para estudos de modelagem e simulação de escoamento um modelo de estrutura definida pode ser usado para a obtenção de dados e resultados de estudo em escoamento de meios porosos.
