Scientific research in the Indian subcontinent: selected trends and indicators 1973-2007 comparing Bangladesh, Pakistan and Sri Lanka with India, the local giant
No full textAs part of a research program to analyse research in Bangladesh we provide a comparison between research indicators related to India, Bangladesh, Pakistan and Sri Lanka. In this investigation we make use of Web of Science (WoS) data as well as Scopus data (using the SCImago website). Special attention is given to collaboration data and to the evolution of country h-indices. A comparison based on relative quality indicators shows that Sri Lanka is the best performer among these four countries. Such a result agrees with the ranking of these countries according to the United Nations' Human Development Index (HDI).Dilruba Mahbuba thanks the International Centre for Diarrhoeal Disease Research, Bangladesh (ICDDR,B), Bangladesh; 68 Shahid Tajuddin Sarani, Mohakhali, Dhaka 1212, Bangladesh for their financial support. Most research for this article was done while she was a member of the Centre. The authors thank the reviewers for some pertinent observations improving the presentation of our contribution

A scientometric analysis of health and population research in South Asia: focus on two research organizations
No full textIn this article we provide a scientometric comparison between two health and population research organizations, namely the International Centre for Diarrhoeal Research in Bangladesh (ICDDR,B) and the National Institute of Cholera and Enteric Diseases (NICED) in India, during the period 1979-2008. We study these two institutes because they conduct similar research and because of their collaboration ties. Data are collected from the Web of Science (WoS) as well as from official records of these two organizations. The analysis presents the evolution of publication activities. Special attention is given to research impact through time series of the institutional h- and R-indices, as well as to the trend in yearly citations received. Types of publications, international collaboration with other countries, top scientists and most cited articles co-authored by scientists from these institutions are highlighted. It is observed that female scientists play a minor role in these two institutes
Year-based h-type indicators
No full textAbstract: We propose new variations of the standard and the real-valued (or interpolated) h-index. More precisely, we propose two different types. For the first type, sources are years, and items are either publications, or citations received or citations per publication. The second type makes use of the speed by which citations are received: it is a diffusion speed index
New definitions and applications of year-based h-indices
No full textAbstract: In this contribution we extend the notion of year-based h-indices and the corresponding h-cores. Real-life examples using the career of the Bangladeshi scientist Firdausi Qadri are provided. Moreover, year-based h-indices of h-indices are calculated for all Bangladeshi publications
The Matthew effect and a relation with concept symbols and defaults
No full textAbstract: In this article a review of Mertons article about the Matthew effect is presented. The authors discuss what they think Merton really meant and link it to the use of concept symbols and defaults. The Matthew effect is linked to the notions of concept symbols and defaults. The diffusion of Mertons ideas in science over time is discussed. Several h- and R-indices related to Matthew publications are derived. Related effects, namely the Podunk effect, the Knudop effect and the Wehttam effect are briefly discussed. Also the Matilda effect is given some attention as is the under representation of women in science and factors explaining this phenomenon
