Between 2004 and 2008, Thomson Reuters indexed 401,649 papers that listed at least
one author address in a United Kingdom region (England, Scotland, Wales, and
Northern Ireland). Of those papers, the highest percentage appeared in journals
classified under the heading of space science, followed by economics & business and
general social sciences. As the right-hand column indicates, the citations-per-paper
average for U.K. research in space science was 41% above the world average (10.06
cites per paper for the U.K. versus 7.14 for the world). United Kingdom-based
researchers surpassed the world mark in all the other fields shown here, with notably
strong performance in plant & animal science (+61% above the world average),
agricultural sciences (55% above), physics (+46%), and pharmacology & toxicology
(+44%).

Between 2004 and 2008, Thomson Reuters indexed 383,345 papers that listed at least
one author address in Japan. Of those papers, the highest percentage appeared in
journals classified under the heading of physics, followed by materials science. As the
right-hand column indicates, the relative citation impact of the nation’s physics research
was 4% above the world average (4.33 citations per paper for Japan, versus 4.16 cites
for the world). Papers from Japan-based Researchers also scored well in immunology
(15% above the world mark) and space science (14% above).

Between 2003 and 2007, Thomson Reuters indexed 75,676 papers that listed at least
one author address in Taiwan. Of those papers, the highest percentage appeared in
journals classified under the heading of computer science, followed by engineering and
materials science. In the latter field, as the right-hand column shows, the impact of
Taiwan-based research in materials registered at 94% of the world average (or 6%
below: 2.71 cites per paper for Taiwan, versus a world average of 2.88 cites per paper).
In agricultural sciences, meanwhile, Taiwan-based researchers scored within 2% of the
world mark. The nation's performance was also comparatively strong in geosciences,
plant & animal sciences, and chemistry.

Between 2003 and 2007, Thomson Reuters indexed 76,440 papers that listed at least
one author address in Brazil. Of those papers, the highest percentage appeared in
journals categorized under the heading of agricultural sciences, followed by plant &
animal sciences and microbiology. As the right-hand column indicates, Brazil has yet to
attain the world impact average in any of the fields shown, although its score in
mathematics for the five-year period was at 89% of the world mark (or just 11% below:
1.28 cites per paper for Brazil versus the world average of 1.44 citations). The nation's
relative impact was also comparatively strong in physics, ecology/environmental, and
geosciences.

The data above were extracted from Thomson Reuters's Essential Science IndicatorsSM
database. This database, currently covering the period January 1997 to December 2007,
surveys only journal articles (original research reports and review articles) indexed by
Thomson Reuters. Articles are assigned to a category based on the journals in which
they were published and Thomson Reuters’s journal-to-category field definition
scheme. Both articles tabulated and citation counts to those articles are for the period
indicated. Naturally, institutions publishing large numbers of papers have a greater
likelihood of collecting more citations than scientists publishing fewer papers. This
ranking is by citations per paper (impact), among those institutions that have collected
10,000 or more citations in engineering journals. For papers with multiple institutional
addresses, each institution receives full, not fractional, citation credit.
