  9. 9. Journal selection
  10. 10. Where to publish <ul><li>It is better to publish one paper in a quality journal than multiple papers in lesser journals. …………. Try to publish in journals that have high impact factors; chances are your paper will have high impact, too, if accepted. </li></ul>Bourne PE (2005) Ten Simple Rules for Getting Published . PLoS Comput Biol 1(5): e57 doi:10.1371/journal.pcbi.0010057 or at SciVee

  13. 13. Impact factor <ul><li>Performance measure for journals </li></ul><ul><ul><li>“… it is also used for assessment of the quality of individual papers, scientists and departments. For the latter a scientific basis is lacking, as we will demonstrate in this contribution” (Opthof, 1997) </li></ul></ul><ul><ul><li>Opthof, T. (1997). Sense and nonsense about the impact factor.
