There are several aspects to completing business ethics research. Here's what I recommend doing:
First, brainstorm. Read about social justice issues that effect businesses. Click on the "Social Stakeholders" link above to get a clearer picture of the business issues which impact people.
Secondly, you're going to want some company information. Perhaps you're researching recent legislation on cigarette package labelling. Remember, there's no such thing as a "light" cigarette! Once you've gotten some background on social stakeholders, it's a good idea to research a bit on tobacco companies (i.e. Philip Morris or Liggett).
Then, it's good to find some articles on the company and social stakeholders. These can include journal articles as well as newspaper and magazine articles. Hint: many of the databases located on the "Find Articles" tab allow you to narrow the search to both full-text and scholarly or peer-reviewed journals. Why is this so important? If you're off-campus, you can still get plenty of journal articles in full-text right from Old Westbury Library but you have to let the databases know this is specifically what you want. Once inside the database, you'll see helpful links to narrow your search.
Don't forget to properly cite all this good research! Go to Purdue OWL (Online Writing Lab) to see how to properly cite in APA, MLA, and more. Or click on the "Write and Cite" tab in the upper right corner of the page for additional citation style guides and information.
Finally, remember to plan some time for your research. Much like cooking a fine meal, good research takes time.
