This doctorial dissertation would have remained a dream had it not been for
the support of several people in the journey of my life. I would like to thank a
number of people who have contributed to the final result in many different ways.
To commence with, I pay my obeisance to GOD, the almighty to
have bestowed upon me good health, courage, inspiration, zeal and the light.
After GOD, I express my sincere and deepest to my supervisor and guide
Dr. E. John Suriyakumar, Former Head and Associate Professor, Department of
Commerce, Madras Christian College, Chennai, who ploughed through several
preliminary versions of my text, making critical suggestions and posing challenging
questions. His expertise, invaluable guidance, constant encouragement,
understanding, patience and healthy criticism added considerably to my experience.
Without his continual inspiration, it would have not been possible to complete this
study. I thank him for the support and guidance extended.
