Trace and describe the development of the theory

Trace and describe the development of the theory Describe or summarize the theory Take one major concept ( which in my case placental transfusion) define it theoretically and operationally ( in my case there are a lot of ways to measure it direct and indirect) use the most common method of measuring which is measuring hematocrit and hemoglobin at 48 hrs after birth, but write briefly about the other methods for example ( biotinylated blood method is not used because of the ethical consideration of using radiation in healthy newborns). By the way one of the ways which very important is measuring the residual blood volume form the placenta Identify the independent variable and the depended variable ( in my case Placental transfusion is the independent variable, and hematological parameters are my dependent variable What are the relational statements and propositions and assumptions What are the parameters for application Back up the empirical data that supports this theory ( if there were any studies that tested this theory — Mercer ( an author) used this theory in all of her research studies
