Introduction: Lung cancer is the leading cause of years of life lost because of cancer and is associated with the highest economic burden relative to other tumor types. Research remains at the cornerstone of achieving improved outcomes of lung cancer. We present the results of a comprehensive analysis of global lung cancer research between 2004 and 2013 (10 years). Methods: The study used bibliometrics to undertake a quantitative analysis of research output in the 24 leading countries in cancer research internationally on the basis of articles and reviews in the Web of Science (WoS) database. Results: A total of 32,161 lung cancer research articles from 2085 different journals were analyzed. Lung cancer research represented only 5.6% of overall cancer research in 2013, a 1.2% increase since 2004. The commitment to lung cancer research has fallen in most countries apart from China and shows no correlation with lung cancer burden. A review of key research types demonstrated that diagnostics, screening, and quality of life research represent 4.3%, 1.8%, and 0.3% of total lung cancer research, respectively. The leading research types were genetics (20%), systemic therapies (17%), and prognostic biomarkers (16%). Research output is increasingly basic science, with a decrease in clinical translational research output during this period. Conclusions: Our findings have established that relative to the huge health, social, and economic burden associated with lung cancer, the level of world research output lags significantly behind that of research on other malignancies. Commitment to diagnostics, screening, and quality of life research is much lower than to basic science and medical research. The study findings are expected to provide the requisite knowledge to guide future cancer research programs in lung cancer. © 2016 International Association for the Study of Lung Cancer.

This paper describes the process by which almost all authors of papers in the Web of Science (WoS) can be characterised by their sex and ethnicity or national background, based on their names. These are compared with two large databases of surnames and given names to determine to which of some 160 different ethnic groups they are most likely to belong. Since 2008 the authors of WoS papers are tagged with their addresses, and many have their given names if they appear on the paper, so the workforce composition of each country can be determined. Conversely, the current location of members of particular ethnic groups can be found. This will show the extent of a country’s “brain drain”, if any. Key results are shown for one subject area, and inter alia it appears that the majority of researchers of Indian origin who are active in lung cancer research are working in the USA. But East Asians (Chinese, Japanese and Koreans) tend to stay in their country of birth. © 2015, The Author(s).

Most physical science research papers are universal in their interest and are published in international journals in English. However much social sciences research is of primary interest to readers in the authors' country and so is often published in the national language and in journals not processed for the SSCI. We wondered if it was possible to estimate the shortfall in coverage of this research by the SSCI by comparing the ratio of papers from a given country in the SSCI only to the numbers in both the SCI and SSCI with the corresponding ratio for the USA, with account taken of the relative expenditures on social sciences and medical research. For this purpose, we examined sets of papers with each of a selected title word chosen from one of four subject categories, and found, as expected, that Anglophone countries showed much less shortfall than the large continental European ones (France, Germany, Italy, Spain) or those in east Asia (China, Japan, South Korea). The data in the paper can be used to estimate how many social sciences papers are likely to be "missing" from the SSCI for the leading countries. © AIT Austrian Institute of Technology GmbH Vienna 2013.

Background While the media may significantly influence public attitudes and government policies affecting the research agenda, how mental health research is reported in the media has been virtually unstudied. The aim of this study was to examine stories concerning mental health research published on the British Broadcasting Corporation (BBC) website between 1999 and 2008 and in New Scientist between 2008 and 2010.Method Stories were retrieved from on-line archives. Story content was coded and assessed against: 'disease burden' of mental disorders; the general corpus of research papers in mental health and the countries from which they originated; the journals in which cited papers were published; and funding sources.Results A total of 1015 BBC stories reporting mental health research and 133 New Scientist stories were found. The distribution of stories did not reflect 'disease burden'; research on dementia was over-represented, while depression and alcohol were under-represented. There was an emphasis on biological research while stories on psychological interventions were rare. UK research was over-represented. Research funded by government and private non-profit sources was over-represented. Commentators from Alzheimer's Disease charities were prominent.Conclusions Consideration of reported stories may suggest approaches to working with the media to improve the public understanding of, and support for, mental health research. The role of commentators may be especially important. © 2011 Cambridge University Press.

This paper uses two large databases, one of given names and one of family names, to categorise the names of researchers from Italy, Sweden, the UK and the USA whose papers in astronomy and oncology were published in 2006-2007 and in 2011-2012 by sex (gender) and ethnicity or national origin. For all the countries, there were relatively many more females publishing papers in oncology than in astronomy, but their share of contributions was lower than the percentage of researchers. Sweden and the UK had much higher percentages of both other European and Rest of the World researchers than Italy did. US researchers with non-European names were categorised in six main country groups. The ones with the greatest presence were Chinese (mainly Mandarin) and South Asians (mainly Indians). The method could be adapted to investigate the progress of women in research in many other countries, and the role played by non-national researchers in their scientific output. © 2013 Akadémiai Kiadó, Budapest, Hungary.

Cancer research outputs in India have expanded greatly in recent years, with some concomitant increase in their citation scores. Part of the increase in output is attributable to greater coverage in the Web of Science of Indian journals, which are more clinical than international ones, and much less often cited. Other measures of esteem have also increased, such as the percentage of reviews and the immediacy with which Indian cancer articles are cited. Most of the output came from just nine of the 35 Indian states and Union Territories, led by New Delhi and Maharashtra. The distribution of the amount of research by cancer site correlates moderately positively with the relative disease burden, with mouth (head and neck) cancer (often caused by the chewing of tobacco or areca, betel or paan) causing the highest number of deaths and also being well researched. We also analysed the articles by type of research, with articles in genetics and chemotherapy being the most numerous. For articles published in 2009-2010, data were available on the funding acknowledgements, and we found, as expected, that articles in clinical subjects were less often supported by external funding than ones in basic research. The major source of support was the Government of India, with relatively small contributions from charities and industry, unlike the situation in the UK and other western European countries. © 2012 Akadémiai Kiadó, Budapest, Hungary.

The Democratic People's Republic of Korea (North Korea) is one of the world's most secretive and reclusive states. In scientometrics, even the United Nations, which compiles data from every country of the world, has been able to do little beyond counting the few scientific papers made publicly available (UNESCO 2010). The world could benefit from knowing more about North Korean science, which is quite well developed-witness all the concern about their nuclear energy and rocket launches. Here an analysis is presented of the North Korean presence in the world's scientific literature, and of the possibilities for collaboration which offers a mechanism for positive development for their citizens and also for their neighbours. © 2013 Akadémiai Kiadó, Budapest, Hungary.

The organisation of cancer research is critical to its overall creativity and productivity. Cancer centres are a major organisational structure for this research, however, little is known about their effect on research or how national policy-making intersects with this complex policy nexus. This study of the evolution of United Kingdom cancer centres (UKCC), part of a wider European and United States programme, uses a bibliometric analysis of research activity prior to the creation of the NCRI and after its formation (1995-2004/5). In terms of critical research mass UKCC are very heterogeneous with a fourfold difference between the top and bottom quintiles. UK centres published just over one eighth of the total UKCC in 1995 but almost a quarter by 2004. This centrification occurred in the absence of any national strategy. Overall these centres conduct more fundamental (laboratory-based) research than that being conducted in the wider network but this hides major heterogeneity. UKCC collaborate with European investigators in 5-28% of all their outputs and with USA the range is between 6% and 21%. We have also derived new measures of research impact on clinical management and the general public as well as the impact of national policy on research assessment for certain types of cancer research. © 2011 Published by Elsevier Ltd.

New Scientist is a British weekly magazine that is half-way between a newspaper and a scientific journal. It has many news items, and also longer feature articles, both of which cite biomedical research papers, and thus serve to make them better known to the public and to the scientific community, mainly in the UK but about half overseas. An analysis of these research papers shows (in relation to their presence in the biomedical research literature) a strong bias towards the UK, and also one to the USA, Scandinavia and Ireland. There is a reasonable spread of subject areas, although neuroscience is favoured, and coverage of many journals-not just the leading weeklies. Most of the feature articles (but not the news items) in New Scientist include comments by other researchers, who can put the new results in context. Their opinions appear to be more discriminating than those of commentators on research in the mass media, who usually enthuse over the results while counselling patience before a cure for the disease is widely available. © 2010 Akadémiai Kiadó, Budapest, Hungary.
