An investigator planning to study behavioral changes during alcohol intoxication will pay subjects $600 for 6 hours of testing that includes drinking a moderate level of alcohol and completing several written questionnaires. He plans to recruit college students taking his courses, as well as economically disadvantaged and homeless people. Which of the following is the most important for the investigator to address before submitting the protocol to the IRB?

Potential undue influence or coercion of subjects

Explanation:

Coercion means influencing or making somebody to act or do something by forceful means or by threatening them.

In the context, a researcher requires human subjects to investigate or do a study on his research on the affect of alcohol intoxication in the behavioral changes of them. For this he will pay $600 to the subjects  for testing them for 6 hours.

Thus before submitting the protocol to the Institutional Review board, (IRB), he must be careful to note that none of his subjects either influenced forcefully or threaten to participate in his research work.  

well, paralell is parallel. i am providing links to .

hope this !

a series circuit is one with all the loads in a row. there is only one path for the electricity to flow. if this circuit was a string of light bulbs, and one blew out, the remaining bulbs would turn off.

unlike in series circuits, a charge in a parallel circuit encounters a single voltage drop during its path through the external circuit. the current through a given branch can be predicted using the ohm's law equation and the voltage drop across the resistor and the resistance of the resistor.

a parallel circuit has certain characteristics and basic rules: a parallel circuit has two or more paths for current to flow through. voltage is the same across each component of the parallel circuit.

what is the other part to the question
