Bottom Line: Studies in rats show that the active ingredient in Garcinia Cambogia can inhibit a fat producing enzyme called Citrate Lyase and increase serotonin levels, leading to significant weight loss. A Look at Some Human Studies Fortunately, I also found several human studies on Garcinia Cambogia. All of these studies are so-called randomized controlled trials, which are the gold standard of scientific experiments in humans.
The biggest of the studies included 135 overweight individuals, which were split into two groups (7): Treatment group: 1 gram of Garcinia Cambogia Extract, 3 times per day, taken 30 minutes before meals.
I have put together this post to explain what a research paradigm is, which includes ontology, epistemology, theoretical framework and methodology, and why it is important for your research or PhD.
Research paradigms and research methods Each of the paradigms discussed above has definite research methods which can be used in carrying out scientific investigation. Positivism which emphasizes objectivist approach to studying social phenomena gives importance to research methods focusing on quantitative analysis, surveys, experiments and the like.
Describing something as a ‘research paradigm’ means that it is an established model, accepted by a substantial number of people in aresearch community. For example, tt could be argued that positivism and interpretivism are (rival) paradigms of research within sociology. Each academic discipline may have its own research paradigms. The most quoted definition of paradigm is Thomas Kuhn's (, ) concept in The Nature of Science Revolution, i.e. paradigm as the underlying assumptions and intellectual structure upon which research and development in a field of inquiry is based.
Research methods refers to the more practical issues of choosing an appropriate research design – perhaps an experiment or a survey – to answer a research question, and 5/5(18). research methodologies and methods that are often presented as competing paradigms and therefore as against each other. This paper is a humble attempt to discuss and clarify research.
