A spatial scientometric analysis of the publication output of cities worldwide

In tandem with the rapid globalisation of science, spatial scientometrics has become an important research sub-field in scientometric studies. Recently, numerous spatial scientometric contributions have focused on the examination of cities’ scientific output by using various scientometric indicators. In this paper, I analyse cities’ scientific output worldwide in terms of the number of journal articles indexed by the Scopus database, in the period from 1986 to 2015. Furthermore, I examine which countries are the most important collaborators of cities. Finally, I identify the most productive disciplines in each city. I use GPS Visualizer to illustrate the scientometric data of nearly 2200 cities on maps. Results show that cities with the highest scientific output are mostly located in developed countries and China. Between 1986 and 2015, the greatest number of scientific articles were created in Beijing. The international hegemony of the United States in science has been described by many studies, and is also reinforced by the fact that the United States is the most important collaborator to more than 75% of all cities. Medicine is the most productive discipline in two-thirds of cities. Furthermore, cities having the highest scientific output in specific disciplines show well-defined geographical patterns.

Global scientific production on GIS research by bibliometric analysis from 1997 to 2006

A bibliometric analysis was applied in this work to evaluate global scientific production of geographic information system (GIS) papers from 1997 to 2006 in any journal of all the subject categories of the Science Citation Index compiled by Institute for Scientific Information (ISI), Philadelphia, USA. ‘GIS’ and ‘geographic information system’ were used as keywords to search parts of titles, abstracts, or keywords. The published output analysis showed that GIS research steadily increased over the past 10 years and the annual paper production in 2006 was about three times 1997s paper production. There are clear distinctions among author keywords used in publications from the five most productive countries (USA, UK, Canada, Germany and China) in GIS research. Bibliometric methods could quantitatively characterize the development of global scientific production in a specific research field. The analytical results eventually provide several key findings.     

Authorship analysis of specialized vs diversified research output

The present work investigates the relations between amplitude and type of collaboration (intramural, extramural domestic or international) and output of specialized versus diversified research. By specialized or diversified research, we mean within or beyond the author’s dominant research topic. The field of observation is the scientific production over five years from about 23,500 academics. The analyses are conducted at the aggregate and disciplinary level. The results lead to the conclusion that in general, the output of diversified research is no more frequently the fruit of collaboration than is specialized research. At the level of the particular collaboration types, international collaborations weakly underlie the specialized kind of research output; on the contrary, extramural domestic and intramural collaborations are weakly associated with diversified research. While the weakness of association remains, exceptions are observed at the level of the individual disciplines.     

Does the concentration of scientific research funding in institutions promote knowledge output?

Basic research is the main powerhouse of a country’s potential for continuous economic growth, and national-level scientific research funding is an important source of capital that supports this basic research. Given these observations, this paper takes micro-level data from projects funded by the Department of Management Sciences in the National Natural Science Foundation of China between 2006 and 2010 to examine the relationship between the efficient use of research funding and the level of concentrated funding in certain research institutions. In contrast to the positive externalities produced by the concentration of R&D activities, our study finds that the accumulation of scientific research funding at the institution level is negative correlated with the knowledge output of the principal investigators of projects within the research institution. We explore the sources of the negative correlation and discuss some policy implications.     

Scoring research output using statistical quantile plotting

In this paper, we propose two methods for scoring scientific output based on statistical quantile plotting. First, a rescaling of journal impact factors for scoring scientific output on a macro level is proposed. It is based on normal quantile plotting which allows to transform impact data over several subject categories to a standardized distribution. This can be used in comparing scientific output of larger entities such as departments working in quite different areas of research. Next, as an alternative to the Hirsch index [Hirsch, J.E. (2005). An index to quantify an individuals scientific research output. Proceedings of the National Academy of Sciences of the United States of America, 102(46), 16569–16572], the extreme value index is proposed as an indicator for assessment of the research performance of individual scientists. In case of Lotkaian–Zipf–Pareto behaviour of citation counts of an individual, the extreme value index can be interpreted as the slope in a Pareto–Zipf quantile plot. This index, in contrast to the Hirsch index, is not influenced by the number of publications but stresses the decay of the statistical tail of citation counts. It appears to be much less sensitive to the science field than the Hirsch index.     

Academic Publishing in India: Sites of Reform and Resistance

Concentrates on the academic publishing sector within India, promoting three sites of resistance to historical (colonial) publishing processes identified as deficiencies for India’s growing academic publishing market. For a framework, the research draws on postcolonial theory, particularly the body of work assessing the means by which large academic publishers tightly control access to scientific output in many developing countries. It argues that although the historical constraints to academic publishing in India are diminishing, careful socioeconomic planning, recognising the development of a unique digital culture in India, are pivotal for a revitalised, local academic publishing program to grow and succeed.

Double media distortions for science communication – an analysis of ‘compiled science news’ transforming in Taiwan

Scientific news is one of the major resources that help the public to understand new scientific knowledge. The latest technology in research and development primarily utilizes English as the language of communication in academic journals and scientific communities. Compiled science news therefore has become a major agent for many non-Western societies to understand the latest technological developments. For this reason, this study aimed to investigate the meaningful change among transforming processes of imported science news from ‘original scientific research’ and ‘overseas news reports,’ to ‘domestic compiled science news.’ The research findings showed that scientific knowledge categories of compiled science news in Taiwan appeared to be apparently unbalanced, and the compiled skills present obvious weaknesses. Furthermore, more seriously compiled science news in Taiwan has continually suffered from the ‘double media distortion’ syndrome. The first distortion appeared from the ‘original scientific research’ to the ‘overseas news reports,’ and the second was from the ‘overseas news reports’ to the ‘domestic compiled science news.’ Such situations are very different from the Western world and could also be a common problem for all non-Western societies.
