Explain the differences between Concept-Centric and Author Centric literature analysis!
Both, the analysis of the literature and the writing of the analysis, can be performed in author or concept centric ways.
When working author centric sources are listed by paper/author and concepts presented in an article are just listed. The analysis is formulated in an author centric way stating which author presented certain concepts:
Example: Krasnova (2020) reports that Social Media Research is important.
When working concept centric a table might list concepts and all authors who wrote about it. The analysis is formulated based on the concept and differences are shown when authors disagree
Example: Studies report that SMR is important (Krasnova 2020) but other researchers disagree and state that it isn't (Gronau 1994)
