What is convergence theory in sociology?
Convergence Theory. In studying the economies of developing countries to see if they go through the same stages as previously developed nations did, sociologists have observed a pattern they call convergence. This describes the theory that societies move toward similarity over time as their economies develop.

Emergent norm theory hypothesizes that non- traditional behavior (such as that associated with collective action) develops in crowds as a result of the emergence of new behavioral norms in response to a precipitating crisis. The norms that develop within crowds are not strict rules for behavior.

What is disease theory?
The germ theory of disease is the currently accepted scientific theory for many diseases. It states that microorganisms known as pathogens or “germs” can lead to disease. These small organisms, too small to see without magnification, invade humans, other animals, and other living hosts.
When was germ theory accepted?
By the 1890s, wider acceptance of germ theory resulted in the emergence of the science of bacteriology, and new research revealed that antiseptics were not the only way to control infection.

Which study design is best?
Hierarchy of Evidence
| Clinical question | Suggested best study design |
|---|---|
| Diagnosis | prospective, blind comparison to a gold standard |
| Therapy | RCT > cohort > case control > case series |
| Prevention | RCT > cohort study > case control > case series |
| Prognosis | cohort study > case control > case series |
