Citizen Science and Scientific Citizenship: Same Words Different Meanings?

This paper sets out to explore the relationship between the still developing phenomenon of citizen science and what I will refer to as ‘scientific citizenship’. Are they essentially synonyms or do they point in different directions? Since both terms are very broad in scope, it may be that no definitive answer is possible (unless that answer is ‘it all depends’). Nevertheless I believe the question is important, not least in throwing some critical light both on the citizen science movement(s) and on the possibilities for the democratic governance of science and technology.
