This fifth volume of the JIDR is devoted to a wide range of research themes, which are all
linked to the concepts of learning, motivation and happiness, both implicitly and explicitly. The
discussions in these articles highlight several recurring and yet under-researched issues in these
fields. The most critical of these themes is what leads to excellence in learning, well being and optimism levels. In publishing this symposium, we believe that our 18 authors offer pertinent reflections
upon this valid question.
