Participation solely in the acquisition of funding or the collection of data does not justify authorship cheap 100mg voltaren. One useful technique is to agree on the number and role of the co-authors before 7 THE A–Z OF MEDICAL WRITING the article is written (see brief setting) generic 100 mg voltaren fast delivery. This should limit the practice of people jumping aboard once all the work has been done. The real cause of the trouble is the fact that authorship is now one of the main international performance indicators for scientists and, less obviously, for doctors. There is no reason to believe that the ability to publish in an English language journal should predict the clinical performance of a Dutch doctor, but that is currently a fact of life, and until the system is reformed conflicts will exist between those who want some easy points (and perhaps get back to their proper jobs) and editors who feel that this is somehow not playing the game. Meanwhile, the current trend is for journals to add lists explaining who did what. If this is the style of your target journal, then follow it (see evidence-based writing). Bad writing I take a pragmatic view and define bad writing as writing that fails to get the desired message across to the target audience (see brief setting). The writing may read easily and appear plausible but, alas, the arguments depend on facts that appear to be, or later turn out to be, not true (see scientific fraud). The author has chosen words and constructions with which the audience is not familiar (see jargon). This can be fixed by altering sentences and paragraphs, though it takes considerable time and is difficult to do well. These are those pieces of writing that you gamely wade through, but by the 8 BAD WRITING end have no idea why (see brief setting; message). If the writer cannot define a clear message, then the reader will be unable to, and the writing will be doomed to fail. Balanced feedback When people ask us to comment on their writing, we tend to shower them with criticism (see correcting the work of others). Whenever you are asked your opinion on a piece of writing, first establish the audience for which is intended. Read the piece quickly, after which you will be in a position to make up your mind on the following key questions.

Dashed and dotted vertical lines in (d) purchase voltaren 50mg mastercard, (e) and (f ) generic voltaren 50 mg visa, (g) indicate the onsets of the corticospinal peak and of the extra facilitation on combined stimulation, respectively. The vertical arrow indicates that the two volleys arrived synchronously at the segmental level of the motoneurone when TMS was elicited 3 ms after the MC volley.
