If there is a researcher who is currently not associated with any research institution, university or college , for example he is un-employed or doing his own business etc. , who is interested in doing research using his own resources what can he do. On option is that he can show his affiliation with his ex-institute but as a matter of fact he is not actually doing research with that institution. What can he do in this situation please suggest some feasible options. And finally if he shows his affiliation with his ex-institute is it against any publication laws/ethics?
