Scientific Initiative: Literature Synthesis

  Literature Synthesis


Literature synthesis is a process of analyzing various material (textual, statistical, graphical, programming, and other) to understand the studied phenomenon by defining the differences, similarities, relationships, and new ideas, which emerge after interpreting published information, statements, arguments. 


Analysis of published literature is a process of asking questions about the information, meaning, goal, and implication of published research. Questions based on -  what, why, when, where, who - provide an insight for analysis of published literature, evaluation, and interpretation. 
 

Four synthesis types are defined from integrative literature reviews

  • Research agenda - identified from the critical analysis through the provocative question or proposition that is used for the next studies
  • Conceptual constructs - provides an analysis of the classification of constructs to classify previous research, which provided the direction for new theories
  • Alternative models or conceptual frameworks - new thinking about the published topics. Alternative models and conceptions are proposed deriving from critical analysis and synthesis
  • Metatheory - integration, and synthesis of literature review provides the foundation for further development of the metatheory across the theoretical domains

Literature Annotation 
 

Methods

  • Passive - light process (e.g., underlining and highlighting)
  • Active - thought-process (e.g., questions, observation, summary, and other
  • SIFT annotation - symbols, imagery, figurative language, tone, theme)

Questions 

  • What are the question and answer?
  • What are the main ideas and findings in the article?
  • What are the unique methods and techniques?
  • What are the patterns in the published literature?
  • Is there a collaborative pattern in published research? 
  • How this article relevant to the study?
  • What are the important concepts?
  • Individual interpretation 
  Literature Critical Appraisal and Synthesis


Critically Appraised Topic

Critically Appraised Topic (CAT) - is a “summary of a search and critical appraisal of the literature related to a focused clinical question, which should be kept in an easily accessible place so that it can be used to help make clinical decisions”

Dawes, M. (2005). Critically appraised topics and evidence-based medicine journals. Singapore Medical Journal, 46(9), 442.

  Scientific Knowledge


What is a Scientific Knowledge?

  • Description - observational analysis of the phenomenon by describing its characteristics 
  • Analysis - evaluating the studies phenomenon to conclude by testing assumptions through the analytical processes by evaluating studies characteristics 
  • Correlation - analysis of relationships among studied phenomena
  • Comparison - analysis of the differences and similarities 
  • Prediction - predictive forecast on emerging phenomenon based on information and knowledge
  • Control/validation - correlation, cause-effect
  • Categorization - typology, specification 
  • Explanation - study hypothesis, research questions - what, when, why, how, where, who

IT / ACCESS ISSUES
When we went to HPCON Charlie and shifted back to increased telework, IT changed how they route network traffic, and IP authentication on base is not consistent. Read more here. You may be prompted to login via EZproxy Remote Access, even when on base.  If you are experiencing access issues with Browzine or other websites/databases, try using the Firefox browser. If trouble persists, please contact us with a description of the issue.
