Social awareness is the active process of seeking out information about what is happening in the community in which we live. It helps us to understand what others think about you. Review articles are a summary of the current state of understanding on a particular research topic. They analyze or discuss research previously published by scientists and academicians rather than reporting novel research results. Review article comes in the form of systematic reviews and literature reviews and is a form of secondary literature. Systematic reviews determine an objective list of criteria and find all previously published original research papers that meet the criteria. They then compare the results presented in these papers. Literature reviews, by contrast, provide a summary of what the authors believe are the best and most relevant prior publications. The concept of "review article" is separate from the concept of peer-reviewed literature. It is possible for a review to be peer-reviewed, and it is possible for a review to be non-peer-reviewed.
