Open Science

Life cycle and taskforce

Radboud University and our research institute (Radboudumc Research Institute for Medical Innovation) see Open Science as the norm in 2030.

This means much more than publishing all papers in Open Access journals. Open Science is about increasing impact in the scientific and societal domains by sharing research materials and codes, making data available for reuse, enhancing reproducibility of research, and involving all relevant stakeholders, including citizen and patients. Our research institute's taskforce (the Open Science Taskforce) is there to stimulate the cultural, policy and professional changes to roll out Open Science in its fullest scope.

The entire research cycle can be open. The taskforce focuses on four domains:

• Open Access
• Open and FAIR data
• Citizen Science and Public Engagement
• Reproducibility

Open Access

Open Access publishing ensures free and unrestricted access to scientific knowledge, promoting transparency, education, and innovation without publisher-imposed copyright barriers. For researchers, it enhances visibility, boosts citation potential, and amplifies the overall impact of their work.
Radboudumc fully endorses the principles of Open Access and actively monitors the percentage of articles made openly available. In 2025, 94% of publications from Radboudumc (co-)authors were published Open Access. This is a milestone we are proud of, but our work does not stop here. We remain committed to advancing publishing practices that are Open, Fair, and of the highest quality, ensuring that scientific knowledge is accessible to all and contributes to better healthcare and innovation.
Additional information about Open Access can be found on the general website on Open Access.

• Support for Publishing

  The Radboud University Library supports Radboudumc researchers in publishing their research articles Open Access, including financial deals with scientific journals, making the publication available free of charge via the Radboud Repository and the publication services of Radboud University Press. Advice is also given on Open Access licensing and how to avoid publishers of dubious quality. Curious on how and where you can publish your research? Please visit this Radboud University page or all available support concerning the Open Access.

• Articles of Radboudumc (co-authors) are behind a paywall, how can I retrieve the full-text?

  You can find the full-text of all articles published by a Radboudumc (co-)author via:

  • Google Scholar: Look up the article in the search engine. To the right of the title you see a link “[PDF] ru.nl”. You find the PDF stored in Radboud Repository by clicking on this link.
  • Google search: Search for the title of interest between quotation marks. e.g. “title” the Radboud Repository will be among one of the first 5 hits.
  • Unpaywall browser extension: Visit the website unpaywall and install the browser extension. When browsing articles, the extension automatically looks for full text PDFs, including PDFs stored in the Radboud Repository.
  • Look up article directly in Radboud Repository: Go to the Radboud Repository and search for your title (search takes a few seconds). If the number of hits are too many, filter on “title contains”, and apply.

  Closed-access publications are still made publicly available through the Dutch copyright provision Taverne. When the six month embargo period ends, they are added to the Radboud Repository. Find more information here.

• Help with avoiding questionable journals

  How do you guarantee the quality of an open access journal? And how do you recognize predatory publishers who abuse the open access publishing model? The following organizations will help you find open access journals of a good quality.

  • Use the checklist Think Check Submit to judge whether a journal is trustworthy or not.
  • Check whether publishers clearly disclose their peer-review process and Open Access fees. Missing or vague information may signal potential predatory practices. 
  • Check if the journal has a recent Journal Impact Factor listed in Journal Citation Reports (JCR). A verified JIF indicates recognition and quality standards; missing or fake metrics can signal predatory practices.
  • Look for mentions of the journal or publisher on Retraction Watch. Frequent retractions or misconduct reports may point to integrity issues and questionable editorial practices.
  • The Open Access Scholarly Publishers Association (OASPA) screens all members on integrity, quality and transparency.
  • The Committee on Publication Ethics (COPE) offers guidelines for integrity in research and research publications.

Citizen Science and public engagement

• Citizen science around the world

  Citizen science in the fields of ecology, biodiversity, astronomy, and climate science often entail data collection activities through environmental monitoring. That is, volunteers are asked to record local wildlife sightings (e.g. De Nationale Tuinvogeltelling), track changes in air quality or weather patterns (e.g. Curieuze Neuzen), or classify galaxies from telescope images (e.g. Galaxy Zoo).

  The rise of the internet and mobile technology enables people to participate in scientific projects from around the world, making it easier to contribute from anywhere. This involvement allows large-scale data collection that might be otherwise difficult or expensive to achieve.

• Citizen science for health

  Although monitoring activities are present in fields such as medicine, health, and social sciences (e.g., through eHealth apps), ‘citizen science for health’ can extend beyond simple data collection. In these areas, lay people may also engage with professional scientists in activities like formulating research questions, designing appropriate recruitment and data collection methods, gathering information, conducting experiments, analyzing data, and helping to disseminate findings in ways that effectively reach the wider public.

  This active engagement enables citizen scientists to contribute to multiple stages of the research process, facilitating a more inclusive and comprehensive approach to scientific inquiry. The benefits of citizen science include their empowerment, increased scientific literacy among participants, and community engagement. It also democratizes science by making it accessible to a broader population.

  It is advised to work according to the 10 principles of citizen science.

Reproducibility

Replicability and reproducibility are increasingly recognized as essential to scientific progress and integrity.

Open science practices play an essential role in supporting these concepts. Replicability (or the extent to which the design, implementation, analysis, and reporting of a study enable a third party to repeat the study and assess its findings), is highly dependent on the openness of, for example, research protocols, methods and data. We cannot replicate research if we have insufficient information about the original study.

Openness in science is therefore a vital driver of replicability. Replication, in turn, allows for an assessment of reproducibility, (or the extent to which the results of the original study agree with those of replication studies - see the figure below). In the end, reproducibility increases our confidence in research findings and promotes the credibility and reliability of science, and open science practices are essential to achieve this goal.
