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.
