Post an explanation of the role of theory in research. Next, identify a theory in respiratory therapy and explain its basic tenets. Then, with this theory in mind, consider your answer to the following question posed by Drs. Burkholder and Burbank in last week’s reading: “What do I have to believe about the world and about human beings in order for me to accept or use this theory?” (p. 27).  Finally, describe the extent to which the epistemological and ontological assumptions of your chosen theory align with the philosophical orientation that reflects your worldview.
