can i submit same research work (multiple submission) in two different journal and conference? after getting the final result i will keep the work either in the journal or in the conference. i have submitted the work to a journal and the review result will take a long time. in the meantime a conference is going to be held and its deadline is nearby. can i submit the work to the conference also? or it will be considered as plagiarism. will it be harmful to my research carrier?
