The CADOS International Course on “Ethics and Integrity in Science” is built to ensure that researchers, particularly junior researchers and doctoral students at the Universidade Católica Portuguesa (UCP), (i) learn the basic foundations, frameworks, ethical principles and values inherent to research ethics and integrity in sciences, (ii) discover how to manage research subjects/participants in sensitive and appropriate ways, and (iii) understand the importance and strategies to conduct research in a way that allows other researchers and society to have trust and confidence in the methods and findings resulting from their research.
