    How I would had liked found your channel before I begin my master or my PhD. Currently, I finishing my PhD and beginning to develop a research proposal for a post-doc position. I do not know if you have already made a video about research proposal for post-doc. If not, I will be very grateful you can do it.
    Great video!

    @digitidea
    Literature review is usually the easiest way to get lost in research. I Have so many questions as I am about to begin my PhD in wind farm modelling and control.
    1. At what stage do I begin to download the literature that have searched for using keywords and advanced search? Is it before I qualify them or after? Would you advise I download all literature from my search of various databases before qualifying them.
    2. About how many literature would you suggest is adequate for a good literature review?
    3. Also do you have any suggestions as to how to manage the process. I mean in terms of downloading, categorizing, folder management etc.. the way I do it is to have a folder for read and unread. I'll like to hear more productive ways to do it.
    4. How much time would be proper to use in studying a relevant literature say an article from a journal? I sometimes get drawn in as I find words or concepts I didn't know before reading the paper and then I pause reading and try to understand those concepts, ideas or words by googling them or reading scientific blogs about the topic and sometimes in the process I encounter another word or concept I have to try to understand. At the end of the day, I might have gone so deep on just one concept or idea from just 1 paper that I haven't even finished reading. Sometimes this can happen so many times in one paper.
    How long will you advise I try to spend on a paper?
    5. What method would you advise I use in taking note of my review? Is there a software or template that one can use take note of findings associated with each literature?
    6. When is the best time to write your literature review chapter? as you study? Or after you are done studying?
    I know I have many questions 😃. I will really appreciate if I can get a detailed response.

    • @digitidea
      @digitidea  4 роки тому

      Qualify first, then start downloading and reading.
      When download, also download the bibtex reference and put in single file.
      For journal paper, 5 hrs, generally avoid reading conference papers until they also have a journal associated.
      Take snap shot of important PARAGRAPHS on Evernote using webclipper (watch my video on how)

    • @AdeyemiAlabi
      @AdeyemiAlabi 4 роки тому

      Thank you very much sir for your response.
      The 5hrs your suggested for reading journals does that include time I use to try to understand concepts I didn't get from the paper. The way I get drawn in as I described earlier is it best practise? Or am I doing it wrong?.

      Google scholar will only show research papers which are authentic and from reputed journals. And there is no chance of getting a deceptive research paper?
