Hi, I hope someone more knowledgeable than me will see this question and answer it:Please advise some reputed universities both in India and abroad whose Ph.d. would be recognized for jobs in India.
I don't know the answer to that, but maybe other people do. The best way is to do an experiment. Go inquire about obs and ask what the impressive institutions are. Interview the interviewers.
As for the topics, I can't choose for you. They are all important. I could tell you what I would like to write:
6. Morale and motivation in BPOs in India
That is what I would choose, but maybe you are interested in something else.
If you keep reading recent articles written by others in your field, the correct topic will suddenly become obious to you. You will say, "Hey! Someone really should conduct a "mixed methods" study, using interviews and questionnaires, to generate theory about the perspectives of rural and semi-urban youth in India about employment in the [name of industry] industry."
You MUST learn about research methods, and you must read lots of the current literature about the topic you choose.
Start with #7 on your list, and search a database of articles so you can find great research studies. Learn fro their examples.
