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 yearIs journal, empirical data will be presented which investigates variables which impact the isafe navigation of the doctoral voyageI. 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.

This issue of the Journal of Doctoral Research is devoted to a wide range of research topics which are all linked, implicitly or explicitly to Internationalization issues. The discussions in these articles - and indeed in current leadership literature in general - highlight number of recurring and yet unresolved issues in these research fields. The most critical of these is whether culture and ethics matter in international business and leadership.

Managing Across Cultures, an essential guide to cross cultural management, has been fully revised and updated, and includes contributions from many of the most outstanding authors in the field of crosscultural and comparative management, such as Nancy Adler, John Child, Charles Hampden-Turner and Fons Trompenaars, Frank Heller, David Hickson, Geert Hofstede, Fred Luthans, Derek Pugh and Rosalie Tung amongst others. Managing Across Cultures is concerned with crosscultural issues, both generally and also more specifically, in Australia, East Asia, Europe, Latin America and the USA. It examines culture not just in the commonly known sense, i.e. nation-states and regional groupings, but also at a corporate culture level. It looks at how managers, manage across different cultures and how they cope with globalization in practice. This is an indispensable text for both teachers and students of international business and management, as well as international executives; and contains descriptions of the most recent thoughts and insightful ideas on globalization and culture, the aculturefreea versus aculture-specifica management debates, area-studies and management education practice.
