The internal migration of Indian scientists, 1981-2003, from an analysis of surnames

Although many Indian surnames are common across the whole country, some are specifically associated with just one of the 35 states and union territories that comprise India today. For example, Reddy comes from Andhra Pradesh and Das, Ghosh and Roy from West Bengal. We investigated the extent to which researchers with names associated with some of the larger states were writing scientific papers in those states, and in other ones, and to see how these relative concentrations (relative to the whole of India) had changed since the early 1980s. We found that West Bengalis, for example, were now significantly less concentrated in their home state than formerly, and that their concentrations elsewhere were strongly influenced by the state’s geographical distance from West Bengal and, to a lesser extent, by the correlation between the scientific profile of their host state and their own preferences (which favored physics and engineering over biology and mathematics). Thus they were strongly represented in nearby Bihar, Assam and Orissa, and much less so in Tamilnadu and Kerala

Identifying author heritage using surname data : an application for Russian surnames

This research article puts forward a method to identify the national heritage of authors based on the morphology of their surnames. Most studies in the field use variants of dictionary-based surname methods to identify ethnic communities, an approach that suffers from methodological limitations. Using the public file of ORCID (Open Researcher and Contributor ID) identifiers in 2015, we developed a surname-based identification method and applied it to infer Russian heritage from suffix-based morphological regularities. The method was developed conceptually and tested in an undersampled control set. Identification based on surname morphology was then complemented by using first-name data to eliminate false-positive results. The method achieved 98% precision and 94% recall rates—superior to most other methods that use name data. The procedure can be adapted to identify the heritage of a variety of national groups with morphologically regular naming traditions. We elaborate on how the method can be employed to overcome long-standing limitations of using name data in bibliometric datasets. This identification method can contribute to advancing research in scientific mobility and migration, patenting by certain groups, publishing and collaboration, transnational and scientific diaspora links, and the effects of diversity on the innovative performance of organizations, regions, and countries

Bibliometrics and scientometrics in India: An overview of studies during 1995-2014Part II: Contents of the articles in terms of disciplines and their bibliometric aspects

This part of the study highlights the contents of the published articles in terms of various disciplines or sub-disciplines and the bibliometric aspects discussed in these articles. The analysis of 902 papers published by Indian scholars during1995-2014 indicates that the main focus of bibliometrics/scientometrics is on assessment of science and technology in India in different sub-disciplines including contributions by Indian states and other individual countries followed by bibliometric analysis of individual journals. Papers dealing with bibliometric laws received a low priority as compared to other subdisciplines of bibliometrics/scientometrics. The analysis of data indicates that the share of theoretical studies using mathematical and statistical techniques which were missing in the earlier period (1970-1994) has increased during 1995-2014. The field of medicine as a discipline received the highest attention as compared to other disciplines

Diaspora and Transnationalism: Concepts, Theories and Methods

Diaspora and transnationalism are widely used concepts in academic as well as political discourses. Although originally referring to quite different phenomena, they increasingly overlap today. Such inflation of meanings goes hand in hand with a danger of essentialising collective identities. This book therefore analyses diaspora and transnationalism as research perspectives rather than as characteristics of particular social groups. The contributions focus on conceptual uses, theoretical challenges and methodological innovations in the study of social ties that transcend nation and state boundaries. This volume brings together authors from a wide range of fields and approaches in the social sciences, as studying border-crossing affiliations also requires a crossing of disciplinary boundaries.Diaspora en transnationalisme zijn veel gebruikte begrippen in zowel het academische als het politieke discours. Hoewel beide termen oorspronkelijk naar heel verschillende fenomenen verwijzen, overlappen ze elkaar tegenwoordig steeds meer. Deze inflatie van betekenis gaat hand in hand met een gevaar van stereotypering van collectieve identiteiten. Daarom analyseert dit boek diaspora en transnationalisme als onderzoeksperspectieven in plaats van als kenmerken van bepaalde sociale groepen
