Aprofessor at big state university proposes to study attitudes about obesity in chile by giving subjects in chile surveys to complete. which is a question that the big state university irb should ask the researcher in order to determine if this study should be reviewed by a local chilean irb or ethics committee as well as the big state university irb

I believe the answer is: Will the researcher have collaborators at the research site abroad?

If the researcher only collaborate with local people, then the permission of the local Chilean committee is all they need. But, if the collaborators would include research site abroad, then it fall to the jurisdiction of the international ethic committee along with big national universities.

muslims have taken his goods and products to different parts of asia an indonesia. sometimes just traveled and trade, but in other occasions, stayed in the place and made a living.

trade was the key for muslims economies to prosper. their commerce routes reached far places like malaysia and java in the 11th century.

another important factor for prosperity was that muslim states served as the middle point for european traders.

they used to travel by land but sailing the seas -the indian ocean- really increase the exportation of products.
