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.

This forth volume of the JIDR is devoted to a wide range of research themes, which are all linked to the concept of diversity; both implicitly and explicitly. In addition, this volume showcases research related to the doctorate journey. As the mission statement and title of our journal suggests, our goal is to promote excellence in publications with a focus on both doctorate studies and also on research disseminated from specific doctorate studies. In next year's journal, empirical data will be presented which investigates variables which impact the 'safe navigation of the doctoral voyage'. Elements such as choice of research methodology, professional background, family issues, career path, gender and choice of supervisor all impact the success rate of PhD candidate. Two of our articles this year therefore showcase the doctoral research journey.
