Hi Timothy, I'm writing my master's thesis, and have 2 question. First, I would like to know how to cite an idea/hypothesis referenced to in a source I'm using. I know it is preferable to track down the primary source, but this can be a challenge with ideas/hypotheses. For e.g., the source I have is by Byler, 2013, where she writes: Among other obstacles that have been cited are the absence of a cultural precedent for safety, as well as the fear of employer retaliation against workers who speak up about safety hazards in the workplace (Buchanan, 2004). However, when I track down Buchanan's work to cite him directly, I find that he is not really the primary source of that idea; he cites John Doe for the idea, and John Doe cites Sally Smith, and so on. Here's another example from another one of my sources: Flynn, 2014, writes: Therefore, it is important to focus on the diverse perspectives, backgrounds and experiences of all workers as well as those of the organization (Koonce, 2001). Again, when I find Koonce's work, I see that he cites someone else for that idea, and that someone else cites someone else... So, my question is, how much tracking down do I have to do to find the primary source? These are just 2 of the many examples I've come across throughout my research. It seems like it would take me a lifetime to find the primary source for each one. But then again, if I don't find the primary source, then I would have too many citations by secondary sources bc my thesis involves more ideas than say quantitative results. My second question is: when reading a paragraph in one of my sources for e.g., where the author cites someone else at the end of the last sentence of the paragraph...How do I know if the previous sentences/ideas in that paragraph were from the source I'm reading or whether they're from the source that is cited at the end of the paragraph? Would I just assume that only that last sentence was from that cited source, and that all previous ones are from the author I'm referencing? I know that when a source cites in the beginning of a paragraph, many times they make it clear that the following sentences/ideas are from that same source by using phrases like, "He also noted..." or "The study also found....". But many times they don't make it clear and it's difficult to know which sentences/ideas are theirs and which are from the source they cite at the end. Thank you in advance!
