Doctoral dissertations in logistics and supply chain management: a review of Nordic contributions from 2009 to 2014 <s> Analysis <s> Purpose ::: ::: ::: ::: – The purpose of this paper is to identify Nordic doctoral dissertations in logistics and supply chain management (SCM) published from the years 2002 to 2008. The paper then seeks to analyze the identified dissertations by categorizing them in various dimensions, including but not limited to subject, methodology, and type of contribution. Subsequently, the paper compares the analysis of the dissertations with results obtained in a previous study that also concerned Nordic dissertations only published from 1990 to 2001, effectively opening up for longitudinal interpretations. ::: ::: ::: ::: ::: Design/methodology/approach ::: ::: ::: ::: – The paper is based on reviews of 70 Nordic doctoral dissertations within logistics and SCM published at relevant Nordic research institutions. All dissertations were reviewed according to a priori determined categories adopted from a similar, previous study in order to strengthen the validity of the longitudinal comparison. ::: ::: ::: ::: ::: Findings ::: ::: ::: ::: – This paper identifies a clear and significant trend towards: more dissertations based on a collection of articles than monographs; more dissertations focusing on manufacturing companies and fewer on carriers; a shift from a focal company perspective to more dyadic and supply chain‐related research and finally; and a decreasing focus on the philosophy in science. ::: ::: ::: ::: ::: Research limitations/implications ::: ::: ::: ::: – Despite the thorough method applied, there is possibility that a few dissertations might not have been identified in this paper. ::: ::: ::: ::: ::: Originality/value ::: ::: ::: ::: – This paper is a continuation of documenting the progress of doctoral work in logistics and SCM within the Nordic countries from the years 2002 to 2008. <s> BIB001 </s> Doctoral dissertations in logistics and supply chain management: a review of Nordic contributions from 2009 to 2014 <s> Analysis <s> The purpose of this article is to examine the output of logistics and supply chain-related dissertation research during the period, 2005–2009, and compare that output with earlier published dissertations from 1970 to 2004. Doctoral students and faculty members can identify emerging areas of research based on the year-by-year trends in topical coverage. Qualitative research analysis of 609 doctoral dissertations published by Dissertation Abstracts International over a 5-year period (2005–2009) was performed. Results suggest that future prospects for additional dissertations being published in logistics and supply chain-related areas are excellent. Many dissertations are emanated from colleges of engineering and business. The prominent research methodologies employed by doctoral students are modeling, simulation, and empirical quantitative methods. More colleges/universities are graduating doctoral students in these areas. Some shift is occurring with respect to the specific colleges/universities that are leading the way in terms of generating the largest number of logistics and supply chain graduates. <s> BIB002
This section is concerned with specific analyses of the 150 reviewed doctoral dissertations. For comparative purposes, the data from the present review are portrayed and analyzed with the categories that are similar to those used by Gubi et al. [13] and Zachariassen and Arlbjørn BIB001 . The results are displayed in tables and are followed with appropriate comments and interpretations. [1990] [1991] [1992] [1993] [1994] [1995] [1996] [1997] [1998] [1999] [2000] [2001] , this shows that there has been a strong increase in PhD production in this research area. A similar pattern is identified by Nakhata et al. BIB002 in their study of doctoral dissertations published by Dissertation Abstracts International in the period of 2005 and 2009. They explain that one reason for such an increase might be an increased level of retiring academicians toward 2020 which creates a stronger market for Assistant Professors. Another explanation could be that there is a drive from the governments to boost the number of annual PhD production in order to support national social, economic and environmental well-being as well as to address major global challenges  . The majority of the Nordic logistics and SCM PhDs come from the Finnish, Norwegian and Swedish research environments. In Denmark, the production is stable with 17 dissertations in the period of 2009-2014. Iceland has reported their first PhD in this period of analysis. Twenty-five Nordic research institutions have produced within logistics and SCM in the period 2009-2014 (see ''Appendix 2'').
