Lesson3#Scientific Research Skills

  1. 1. Scientific Research Skills<br />Scientific Research Skills - D.ALQahtani<br />3<br />
  2. 2. Lessons<br />Scientific Research Skills - D.ALQahtani<br />1- Essentials <br />2- Searching<br />3- Using MeSH<br />4- Working with Results<br />5- Referencing <br />
  3. 3. Scientific Research Skills - D.ALQahtani<br />3- Using MeSH<br />
  4. 4. Scientific Research Skills - D.ALQahtani<br />3- Using MeSH<br />Basically , when we search , we use<br />keywords<br />MeSH terms <br />or /and<br />
  5. 5. Scientific Research Skills - D.ALQahtani<br />3- Using MeSH<br />keywords<br /><ul><li> Is fast and easy - usually finds what you need
  6. 6. Often automatically maps your keyword to the appropriate MeSH term, including it in your search </li></li></ul><li>Scientific Research Skills - D.ALQahtani<br />3- Using MeSH<br />MeSH Search<br />MeSH Retrieves Subjects – Not Words: When you search with a MeSH term, you are searching for a subject<br /> (not a keyword) match<br />
  7. 7. Scientific Research Skills - D.ALQahtani<br />3- Using MeSH<br />Example<br />Searching for the keyword &quot;aids&quot;retrieves articles on : <br />AIDS virus, as well as articles on hearing aids, audiovisual aids, clinical aids, teaching aids etc. <br />Using the MeSH term for AIDS:Acquired Immunodeficiency Syndrome [MeSH] will limit your retrieval to the relevant subject<br />
  8. 8. Scientific Research Skills - D.ALQahtani<br />3- Using MeSH<br />When MeSH Helps and When it Doesn&apos;t ?<br />
  9. 9. Selecting medical subject headings (MeSH)for a search <br />Scientific Research Skills - D.ALQahtani<br />3- Using MeSH<br />can provide much needed focus and precision...<br />
  10. 10. Scientific Research Skills - D.ALQahtani<br />3- Using MeSH<br />Consider doing a MeSH Search<br />Your keyword search results in a retrieval that is off-target<br />F<br />
  11. 11. Scientific Research Skills - D.ALQahtani<br />3- Using MeSH<br />Use MeSHsubheadingsto quickly focus your search on a specific aspect of a topic. For example: &quot;Etiology of aphthous ulcer &quot;, &quot;Genetics of amelogenesis imperfecta&quot;<br />Tip: When your topic contains the word &quot;of&quot; consider selecting MeSH and MeSH subheadings for your search<br /> <br />
  12. 12. Scientific Research Skills - D.ALQahtani<br />3- Using MeSH<br />Also Consider doing a MeSH Search If:<br />Your keyword search results in a retrieval that is Too large<br />
  13. 13. Scientific Research Skills - D.ALQahtani<br />3- Using MeSH<br />In the MeSH database you can also restrict your search tomajor topic headings only. This feature allows you to retrieve articles where your topic is one of themajor points discussed, rather than a secondary focus. <br />
  14. 14. Scientific Research Skills - D.ALQahtani<br />3- Using MeSH<br />MeSH will probably NOT help you if you search<br />A new or emerging medical concept<br />A recently published articles<br />
  15. 15. Scientific Research Skills - D.ALQahtani<br />3- Using MeSH<br />Scenario<br />You need to find articles on drug treatments for aphthous ulcer !<br />
  16. 16. Scientific Research Skills - D.ALQahtani<br />3- Using MeSH<br />To see the difference between searches, start with a keyword search<br /><ul><li> Clear the previous search if it is still active
  17. 17. In the query box, type aphthous ulcer AND drug treatment
  18. 18. Click GO</li></li></ul><li>Scientific Research Skills - D.ALQahtani<br />3- Using MeSH<br />You should retrieve about 1008 citations. This is more than is optimal. More importantly, inspection would show that drug treatment aphthous ulcer is not the main focus of many of these citations. (Some of the articles are about aphthous ulcer , but mention drug treatment of other conditions<br />We need to increase the search precision<br />
  19. 19. Scientific Research Skills - D.ALQahtani<br />STEPS<br />
  20. 20. Scientific Research Skills - D.ALQahtani<br />Locate and Select MeSH Terms From the MeSH database<br />3<br />2<br />1<br />
  21. 21. Scientific Research Skills - D.ALQahtani<br />Locate and Select MeSH Terms From the MeSH database<br />6<br />4<br />5<br />
  22. 22. Scientific Research Skills - D.ALQahtani<br />Locate and Select MeSH Terms From the MeSH database<br />7- click search Pub Med<br />
  23. 23. Scientific Research Skills - D.ALQahtani<br />3- Using MeSH<br />WHY <br />Subheading ( STEP 4) <br />Attaching subheadings to a MeSH term allows you to focus on a specific aspect of your topic. In this example, we retrieved citations about drug therapy of aphthous ulcer . We did NOT retrieve citations where &quot; aphthous ulcer &quot; and &quot;drug therapy&quot; are both mentioned as separate concepts<br />
  24. 24. Scientific Research Skills - D.ALQahtani<br />3- Using MeSH<br />WHY <br />Restrict Search to Major Topic Headings Only( STEP 5) <br />So that your articles will have drug therapy of aphthous ulcer as a major focus<br />
  25. 25. Scientific Research Skills - D.ALQahtani<br />SO, 504 focused citations in your results down from about 1008 retrieved at the beginning of this example<br />
  26. 26. Scientific Research Skills - D.ALQahtani<br />3- Using MeSH<br />Using MeSH terms and subheadings, and restricting your topic to major headings greatly increases your chances of locating relevant results<br />
  27. 27. Scientific Research Skills - D.ALQahtani<br />3- Using MeSH<br />Quick Summery <br /><ul><li> A MeSH search is a subject search
  28. 28. Consider selecting MeSH terms if your search results are off topic or too large
  29. 29. A MeSH search usually results in a smaller retrieval than a keyword search. Selecting MeSH terms limits your search to the MeSH field
  30. 30. MeSH subheadings allow you to quickly focus on one aspect of a topic</li></li></ul><li>Scientific Research Skills - D.ALQahtani<br />3- Using MeSH<br />Quick Summery <br /><ul><li> Consider restricting your MeSH search to Major Topics Only
  31. 31. MeSH will not usually help you if you need to research a new or rare topic or the most recent articles on a topic
  32. 32. Display search sets in Citationformat to view the MeSH terms for each citation.</li></li></ul><li>Scientific Research Skills - D.ALQahtani<br />Reference<br />1- Gustave L. and Janet W. Levy Library of Mount Sinai School of Medicine<br />
