My question is for those who published/publishing a book or editing special journal issues. Generally, the expert persons are invited for such contributions. Frequently, many authors request to extend the submission date. However, at crucial/final stage of submission of article they send you an e-mail stating that they are not able to contribute. Many of my colleagues have came across such situations when some scientists/professors give up at the final stage (sometimes even after extending date of submission).
My query is how to cope up with such non-professional people? Is there anything we can do to tackle such problems? Your suggestions are important?
