Challenges (ISSN 2078-1547) is a unique open access journal. Over the past five years, we have published research proposals, research plans, research or technology ideas, policy studies relating to science and scholarly research, and open contests aiming at solving major challenges. This kind of scholarly content is typically not published in traditional research journals.
As the term of the current Editor-in-Chief Prof. Andreas Manz, will end in 2015, you are encouraged to nominate individuals who you feel should be considered for this position. Self-nomination is also welcomed. In general, the Editor-in-Chief is responsible for the technical content and quality of the journal publications. The Editorial Office will carry out the majority of the administrative work, including the invitation of peer reviewers, correspondence with authors, professional copy editing, English editing of accepted manuscripts, and assistance in promoting the journal.
