The situation described below is very common in Pakistani institutions. Students are always directed by professors/ supervisors to write their name(s) on researched work. Failing in doing so, they would present hurdles inside university/ department. In some cases, supervisors discourage students about research work and afterward publish that work with their own names. Rarely it happens: student reach extreme authorities to defend his/her.
As far as the course of ”Professional and Ethical Issues” is concerned; major universities are teaching this subject in final year to undergraduate students. But how could this teaching affect students (other than passing exam) when you find a huge difference in teaching, saying and doing acts. Actions speak louder than words. Furthermore, (in my opinion) Ethics cannot be learned, it is your inner-self. That is why immediately after starting career, students forget all about ethics and decide on the basis of personal will just because they hardly find any real world example.
With due respect; for effective learning and teaching ethics, nation builders have to rethink about their boundaries, position and sensitivity of their profession. They are those who directly affect the society.
