Congresos y revistas (y revisores)

En la última clase surgió una pregunta muy interesante, si se puede publicar algo que está ya enviado a un congreso o cuan diferentes han de ser dos artículos. Casualmente me han pedido revisar un artículo y en el correo me incluían el siguiente texto:

By the way, we briefly state here our duplicate submission policy, because this issue comes up quite often. It is an IEEE publications rule that if an author submits a paper that has similar material to a previous submission, the author must cite the previously submitted paper (unless the previous submission was rejected). This includes conferences. Furthermore, the multiply submitted papers cannot be identical. The later submission should contain new material unless the paper is highly important or the previous version had errors. The amount of required new material should be inversely proportional to the importance of the paper. For example, suppose a paper is submitted to PTL that is very similar to a published conference paper. If the author failed to cite the conference paper in the PTL paper, the PTL paper should be rejected. If the PTL paper did cite the conference paper but has added no new material, the reviewer can ask the authors to revise it. If the reviewer feels strongly that the material does not warrant republication as a Letter, the reviewer can ask the authors to develop the manuscript into a full paper and submit it to a full-paper journal, such as the Journal of Lightwave Technology.

Creo que es muy clarificador, y que es una respuesta que recoge muy bien el sentido común y la idea general de lo que debe ser un paper y que un congreso.
