            the issue of

         Learn how to…

1. Search newspaper articles from
   LexisNexis Academic.


2. Search academic articles from
   Scopus.
       3-step search process
1. Determine the keywords from your topic.
    electronic waste
2. Determine the relevant databases.
    For newspapers → search
    LexisNexis Academic
3. Apply search strategies to get the relevant
    results.
    Use AND, OR, * , !, ( )
   What’s a search statement?
1. What is it?
    A query string that contains keywords,
    terms and connectors to input into the
    search engine or database.
2. How do I construct one?

    a. Identify keywords and concepts
    b. Learn about connectors
Identify keywords and concepts
• Think of related words or synonyms
• Check that related words are really
  related, e.g. urban and urbane have very
  different meanings!
• Leave out non-concepts terms such as
  ‘issues’, ‘problems’, ‘list’, ‘elaborate’,
  ‘explain’ and so on
    Determine keywords
electronic        waste
gadgets           rubbish
computer(s)       trash
mobile phones
Components
such as
microchip,
lead, precious
metals, plastic
casing
    Consider related concepts
•   Disposal/waste management e.g. recycling,
    reducing volume of waste to landfill
•   Trans-boundary movement of waste e.g. e-waste
    from Japan to China, from Singapore to Indonesia
•   Impact on people’s livelihoods, e.g. by export to
    countries with cheap labour to process waste, are
    we adding to their environment risks, exploitative
    HR practices and feeding the greed of
    ‘entrepreneurs’?
Putting them together …
 electronic            waste
 gadget(s)             rubbish
                       trash


        (electronic OR gadget*)
                 AND
     (waste OR rubbish OR trash)
               Connectors
1. Boolean operators (AND, OR)

2. Truncation (* or !)

3. Parentheses (brackets)
     What does AND do?
           electronic AND waste

              Items with the          Items with
              word                    the word
              ‘eletronic’             ‘waste’



                Articles containing both words


Without AND, ‘electronic’ will retrieve articles with the phrase
‘waste’. This means articles that contains both words will be
retrieved. Your search result is narrower.
      What does OR do?
               waste OR rubbish

              Articles with           Articles with the
              the word                word ‘rubbish’
              ‘waste’




             Articles with either the word ‘waste’
             and ‘rubbish’ and where both terms
             occur anywhere in the document will
             be included

This means articles will have ‘waste’ & ‘rubbish’ anywhere in the
full text will be retrieved. Your search results will be a lot longer.
          Truncation ( * or !)
• The truncation symbol expands your
  search by incorporating all variations of a
  root word
  e.g. communit* includes
     community
     communities
     communitarian
       Role of parenthesis ( )
Why do we put terms within parenthesis?
e.g. waste AND (gadget* OR computer*)
  Parenthsis [pl. parentheses] tells the
  search engine how to prioritise a complex
  search statement. Otherwise, the default
  mode is from left to right.
  ( ) tells it to search ‘gadget* OR computer*’
  first before combining with ‘waste’ using the
  ‘AND’ boolean operator.
          Next step …

                             it tells me that there are more
                             articles found in ST than in SCMP.
