Agenda • What is a Literature Review? • Literature Review Components. • Key Databases. • Internet as a Source of Info.
What is a Literature Review? • Comprehensive collection of information based on a construct. • Means of justifying a research question.
What’s The Point? • The current knowledge base. • Support for the question. • Questions still unanswered. • Opportunity for ideas. • Never complete – only a snapshot.
How Do I Start? • SPECIFY a topic of interest. • Easier to induct than deduct. • Ensures quality if using narrow focus.
Sources of Ideas • Common Sense – does the early bird truly get the worm? • Observations – the role of “serendipity” – Pavlov’s dogs. • Theories – Descriptions of “facts” that organize and explain phenomena. • Also generates new knowledge - additional hypotheses.
Sources of Ideas • PAST RESEARCH – theory/hypothesis generation based on past results.
Vocabulary • Develop a listing of all words that could represent your construct: • “Cats” – cat, feline, kitten, Siamese, pets, animals • Also be sure to consider plural words and alternate spellings. • Orthopedic, orthopedics, orthopaedics
Where Do I Look? • Learn your databases – Pub Med, Current Contents Connect, Psych Info, etc. • Learn your journals – Journal of Vocational Rehabilitation, Journal of Applied Rehabilitation Counseling, Journal of Rehabilitation, Rehabilitation Counseling Bulletin, Rehabilitation Education, RehabPro, Rehabilitation Psychology, Journal of Counseling and Development, etc.
Where To Look • Meet your librarians. • Attend the FREE library classes offered throughout the semester. • Ask the professors and Ph.D. students.
Using The Databases • All databases are different in some shape or form – most upgrade regularly. • When first using, access the HELP or GUIDE option.
What Details? • Booleans – using the AND, OR, and NOT functions. • Truncation – using a portion of a word to locate all similar words. • Ex. – rehab* • Be careful though…. • Ex. – ortho* could pick up orthopedics, orthodontics, orthodox
More Details • Nesting – the combination of Booleans and truncation • Example – (foot OR feet) AND diabet* • Phrase Searching – using quotations to find specific phrases – “functional impact of disability”
How Much Info Is Good Enough? • Depending on your topic’s specificity, the info you need to cover may vary. • Attempt to find the most recent literature available. • Again, a lit review is never complete.
The Databases • Focus on Pub Med and Current Contents Connect (CCC). • The number of databases that will provide info specifically for your topic of interest will vary on subject matter.
E-Journals • Full-text articles via the library web site. • HTML and PDF format – it is advisable to select PDF format if given the option. • Not every journal is available in full-text, which means we still have to go to the library sometimes. • http://www.library.health.ufl.edu/
Pub Med • Pub Med (formerly MedLine) – difficult but comprehensive. • Lots of bells and whistles. • http://www.library.health.ufl.edu/
CCC • Current Contents Connect – most up-to-date. • Also connected to Web of Science and the Journal Citation Report. • http://www.library.health.ufl.edu/
Reference Manager • Not a database, but can be used while searching Pub Med. • Creation of reference pages by entering each source in APA format for you. • Unfortunately, the software is costly and it’s best to find someone who has it already. • http://www.refman.com/
Accessing The Internet Research Implications
Web Searching • Using the Internet to educate/research. • Five major issues need to be addressed when using web sources for research.
Accuracy • How valid is the information – was it done by a professional in the field or by someone with Netscape Composer?
Authority • What are the author’s qualification for providing the information?
Objectivity • Was there bias and/or persuasion in the information?
Currency • Is the information still accurate or up-to-date as it may (or may not say) it is?
Coverage • Great info or does it scratch the surface of the topic – is this good stuff or filler?
Web Site Reliability Resources • When in doubt, use the following sites to offer assistance in determining reliability: • http://www2.widener.edu/wolfgrammemoriallibrary/webevaluation/inform.htm • http://info.wlu.ca/~wwwlib/libguides/internet/eval.html
Sounds Too Risky… • Validity and reliability threats – seek PEER-REVIEWED journal articles. • Critiqued for weaknesses prior to publishing – in theory provides best info. • Consider journal rating.
