Doctoral dissertations in logistics and supply chain management: a review of Nordic contributions from 2009 to 2014 <s> Number and type of dissertations finalized in the period 2009-2014 <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> Number and type of dissertations finalized in the period 2009-2014 <s> Purpose – Scholarly interest in carrying out impactful research continues to remain high. Yet, given that citations of scholarly work can never decrease with time, traditional measures of research impact (such as raw counts of citations) unwittingly discriminate against early career researchers and also make it hard to identify future high impact scholars. In the current study, the paper compares several commonly used measures of research impact to identify one that best normalizes for the effect of career stage. The measure thus applies equally across most career stages, providing a usable impact benchmark for logistics scholars irrespective of seniority level. The paper also aims to present benchmarks on that metric to help logistics scholars identify their research impact vis-a-vis their peers. Design/methodology/approach – Bibliometric data on the research of 702 logistics scholars were collected and analyzed by dividing the scholars into different cohorts based on seniority.

Another interesting finding in the current review is the increase in the share of dissertations that are based on a collection of articles. As given in Table 1 , 92 out of the 150 dissertations (61 %) are based on a collection of articles. Thus, there is a much higher focus on the craft to write academic articles when compared to the share of articlebased dissertations in previous periods (29 % in the period 2002-2008 and 21 % in the period 1990-2001) . This trend supports the predictions previously made by Zachariassen and Arlbjørn BIB001 . One plausible explanation for this development might be an increased amount of public and private resource allocation to research environments based on publications in internationally recognized peer-reviewed journals as well as measures such as impact indicators and H-index (see, e.g., BIB002 ).
