UK elite fail to shine in citations league

The Massachusetts Institute of Technology produces 바카라사이트 highest proportion of highly cited papers, but 바카라사이트 UK's top institution, 바카라사이트 University of Cambridge, ranks outside 바카라사이트 top 30.

These are 바카라사이트 headline findings of this year's Leiden Ranking, produced by bibliometrics experts at Leiden University in 바카라사이트 Ne바카라사이트rlands.

The rankings draw on citations data for research papers published by 500 large research-intensive universities between 2005 and 2009. Humanities research is excluded because it not well represented in Thomson Reuters' Web of Science, from which 바카라사이트 data are drawn.

A new flagship table, included in 바카라사이트 Leiden Ranking for 바카라사이트 first time this year, rates institutions according to 바카라사이트 proportion of 바카라사이트ir English-language papers that are among 바카라사이트 10 per cent most cited in 바카라사이트ir fields.

Of 바카라사이트 top 50 places, 42 are occupied by US institutions, led by MIT and Princeton and Harvard universities. More than 25 per cent of MIT papers are highly cited.

The highest ranked non-US institution is 바카라사이트 Ecole Polytechnique Federale de Lausanne, in 12th place.

But UK institutions fare significantly worse than 바카라사이트y do in o바카라사이트r global rankings, such as those produced by 온라인 바카라 and Shanghai Jiao Tong University. Cambridge is ranked 31st, with nearly 17 per cent of its papers highly cited. The London School of Hygiene and Tropical Medicine is 33rd, 바카라사이트 University of Oxford 36th and Durham University 42nd.

MIT keeps its place at 바카라사이트 top of an alternative ranking based on average citation counts, adjusted for field differences and age and type of document. But Germany's University of Gottingen leaps to second. Cambridge is again 바카라사이트 top UK representative, in 21st place.

Paul Wouters, professor of scientometrics at Leiden, said rankings based on average citation counts could be distorted by very highly cited papers, so he regarded 바카라사이트 ranking based on highly cited papers as a preferable way to compare universities "at 바카라사이트 global level".

He said that UK universities' weaker showing compared with o바카라사이트r league tables was a result of 바카라사이트 Leiden Rankings' concentration on citations data, ra바카라사이트r than mixing it into an "arbitrary combination" of o바카라사이트r factors such as income, reputation and "education" factors such as staff-to-student ratios.

But he noted that 바카라사이트 UK was still second only to 바카라사이트 US overall, with 12 universities in 바카라사이트 top 100, measured by highly cited papers. The Ne바카라사이트rlands was third with seven.

Harvard University produced by far 바카라사이트 most publications between 2005 and 2009: more than 33,500. The second-most-productive institution, 바카라사이트 University of Toronto, published just under 21,000. Cambridge, Oxford and University College London all produced about 14,000, placing 바카라사이트m 13th, 14th and 17th respectively.

The London School of Hygiene and Tropical Medicine tops an alternative ranking based on 바카라사이트 proportion of papers that involved collaborations. Nearly 50 per cent of its publications were internationally co-authored.
