The purpose of this paper is to analyze the disciplinary orientation of scientific publications that were mentioned on different social media platforms, focussing on their differences and similarities with citation counts.

Social media metrics and readership counts, associated with 500,216 publications and their citation data from the Web of Science database, were collected from Altmetric.com and Mendeley. Results are presented through descriptive statistical analyses together with science maps generated with VOSviewer.

The results confirm Mendeley as the most prevalent social media source with similar characteristics to citations in their distribution across fields and their density in average values per publication. The humanities, natural sciences, and engineering disciplines have a much lower presence of social media metrics. Twitter has a stronger focus on general medicine and social sciences. Other sources (blog, Facebook, Google+, and news media mentions) are more prominent in regards to multidisciplinary journals.

This paper reinforces the relevance of Mendeley as a social media source for analytical purposes from a disciplinary perspective, being particularly relevant for the social sciences (together with Twitter). Key implications for the use of social media metrics on the evaluation of research performance (e.g. the concentration of some social media metrics, such as blogs, news items, etc., around multidisciplinary journals) are identified.

Channel management deals with the establishment of an efficient and effective distribution channel. It implies the stepwise development of channel leadership and channel relations. International channel management and the establishment of cross-border relations between exporting suppliers and their foreign subsidiaries and intermediaries are key in international marketing performance (Madsen, 1989; Cavusgil & Zou, 1994; Solberg & Nes, 2002). Li (2003) proves that an export channel is a very complicated phenomenon and a number of factors, both contextual and historical, affect simultaneously the exchange modes and their operation.

This part contains four papers. Even though this volume of AIM primarily concerns exporter–intermediary relations, the first two contributions deal with channel choice and partner selection. The first chapter by Kent Eriksson, Jukka Hohenthal and Jessica Lindbergh, “SME export channel choice in international markets”, tests some of the fundamental factors proposed by the IP model explaining choice of entry mode (accumulation of knowledge of foreign markets determining foreign operation modes). Later developments of the model claim that experience and knowledge of local business relationships are also essential elements of the IP model. Whereas the IP model has been found to hold well for incremental resource commitments, it has – in contrast to transaction-cost theories – produced mixed results concerning its ability to explain operation modes. The authors present findings from research in 494 firms from Sweden, Denmark and New Zealand: factors included in the initial explanation of the IP model explain choice of channel, but later developments of the model do not. Implications are that the foreign market knowledge is, and that more incremental experiential knowledge accumulation is not relevant for export channel choice as regards integrated or non-integrated channel. The results show that for Small and Medium Sized Businesses (SMEs), expected market growth lead to use of integrated channels. Integrated channels make it possible to reap more of the profits from a growing market and to learn faster about what is going on in the market. They also found that use of integrated channels is correlated with cultural distance, contradicting the findings of Johanson and Vahlne (1977) and Kogut and Singh (1988). The IP model therefore offers a rather weak explanation of choice of integrated channel.
