Introduction: language management, ideologies and practices in scientific research

The several challenges posed to Higher Education Institutions by globalisation and internationalisation have been highlighting language issues within scientific research that are related to the naturalisation of English-only policies. Over the last years, this naturalisation has been questioned by some researchers in the area of social sciences, arts and humanities who have discussed the constraints of monolingualism versus the potential of multilingualism in knowledge production, dissemination and circulation. This special issue aims at contributing to a growing debate on language policy and planning within research, by addressing language management, ideologies and practices in diverse key dimensions of scientific research (knowledge construction and dissemination, research assessment, multilingual collaborative research and doctoral education), and bringing together contributors from diversified academic contexts (Brazil, France, Germany, Portugal and Switzerland).This work is financially supported the Fundação para a Ciência e a Tecnologia, I.P. under the project UIDB/00194/2020 and in the scope of the framework contract foreseen in the numbers 4, 5 and 6 of the article 23, of the Decree-Law 57/2016, of August 29, changed by Law 57/2017, of July 19.publishe
