With academic publications purchase erectafil 20mg with mastercard erectile dysfunction type of doctor, however buy erectafil 20mg low price erectile dysfunction among young adults, there is the chance of appeal in certain circumstances. If the editor says that publication of your paper is not a priority then, as with the editors of magazines and newspapers, you must respect that decision (see fairness). However, if you believe that your article has been turned down because the reviewer has made an error and given bad advice, then you should consider an appeal. Under no circumstances should you just blank out the name of the first editor and send it off to another. Find a new market and 112 REJECTION research it (see evidence-based writing). Look at your message: is it right for that market or do you need to adjust it slightly? It will probably take less time than you imagine, and will be more effective than just tinkering with the rejected version. Although most rejected articles are subse- quently published somewhere, occasionally you will write the article that no one will ever accept. The logical time to give up is when editors and reviewers continue to make the same objection – insuffi- cient numbers in the sample, for instance, or offensive to public taste – and you cannot (or will not) do anything about it. This is the time to hold a ceremonial burning – and get on with your life. While unpleasant at the time, they are good for the soul and better for the writing. And it does make that acceptance letter – when it comes – that much more worth while (see acceptance). Generally these will review a situation (or problem), analyse it, and then put some recommendations. This is a specialized type of writing; once you master the technique, you have a powerful tool. Some reports, sadly, are written only because someone has been told to write them; these are pointless. Are you writing to obtain an extra piece of equipment or new member of staff, or to change an existing policy? Are you writing to raise awareness of an issue, or to persuade people to take drastic action, like closing down a hospital? Whatever you decide, be clear in your mind how you will judge success (see effective writing). The more focused you are, the greater the chances of your report being successful (see marketing). Examples might include introduction, background/history, current situation/problem, discussion, recommendations. Look at the reports that have worked before for your audience, and follow the style of the 113 THE A–Z OF MEDICAL WRITING successful ones. Approach each section as if it were a separate piece of writing (see process of writing). Some documents run into trouble because they have to appeal, say, to an audience of professional colleagues who have one set of expectations (see jargon), while at the same time having to convince the non-professionals who will make the decisions. Fortunately there is a solution: write the report for your professional peers, and use the executive summary as your selling tool for the decision makers. Research All types of writing – not just science writing – will fail if the research is inadequate (see bad writing). Research into writing Even those steeped in the harshest traditions of evidence-based medicine can become remarkably cavalier when it comes to making decisions about their writing. But a wide range of evidence exists, both from psychological experiments into readability and from market research carried out privately for commercial publishers. Here is a short selection of some of the main findings: • Long sentences. For going across an A4 page, for instance, you should have a type size of 12 point. BOOKLIST: research into writing • Designing public documents: a review of research, by Elaine Kempson and Nick Moore, London: Policy Studies Institute, 114 RESEARCH INTO WRITING 1994. Useful advice for those designing forms and other docu- ments, with details of many of the experiments on which this advice is based. This classic ranges over typo- graphy and layout, illustrations and tables, effective writing and evaluating design.
