2012 NPI Asia-Pacific
For many years, science in the Asia-Pacific region has been dominated by Japan. However, as seen through the lens of the Nature Publishing Index (NPI), the fastest growth in high-quality research is now coming from other countries — in particular China and Singapore. The 2012 NPI Asia-Pacific presents an analysis of the dynamic changes in the region’s scientific publishing record.

Introduction to the Index
The Nature Publishing Index Asia-Pacific tracks research published in Nature journals from the Asia-Pacific region during the past 12 months, and is updated weekly. The Index provides many different options for users to delve into the data: users can analyze data by institution, country, subject or Nature journal, and can access historical data and graphs. Listings of recently published articles are also provided in the ‘Latest research’ section.
The Index primarily tracks research articles, but data for reviews published in Nature journals is also available. The type of publication can be selected at the top of the institution, country and journal rankings pages. As the Index focuses on primary research articles, the tab for ‘Research articles’ is selected by default. By clicking on ‘Reviews’, data for review articles only can be selected, while clicking on ‘All’ displays data for both primary research articles and reviews.
The corrected count is a score that takes into account the number of affiliated institutions per author and the percentage of authors per institution. It is a decimal fraction up to a maximum of one calculated for each paper for a given institution or country affiliated with the paper, by taking into account the percentage of authors of the paper from that institution or country. All authors are assumed to contribute equally to corrected count, and an author with multiple affiliations is assumed to be divided equally among those affiliations. When an author gives a "present address", "permanent address" or "current address" that affiliation is assumed to not be involved in that author's contribution to the paper and is not included in the corrected count. The rules governing the calculation of corrected counts with respect to the way affiliations are presented are expanded regularly to account for new scenarios and any such additions to the rules are added to the footnotes to the tables.
The number of articles reflects the total number of articles with which a particular institution or country is affiliated according to the stated affiliations of authors in each publication. Institutions and countries are counted once per article. Advance online publications are not included until assigned issue and page numbers.
The institutional rankings track institutions in the Asia-Pacific region (including India and Australasia) according to corrected count. Data for primary research articles (Articles, Letters and Brief Communications), reviews or a combination of both, can be viewed by selecting the appropriate tab at the top of the page. By default, the top 25 institutions are listed; clicking on ‘Show all’ at the bottom of the list will display all of the institutions.
Clicking on the number in the ‘Articles’ column displays a list of all the articles from that particular institution. The list includes the journal name, article title and the corrected count of that institution for that article. Hovering over the article title reveals the article DOI and clicking on the title opens the article on nature.com.
Similar to the institution rankings, the country rankings are listed according to corrected count and can be filtered by selecting the article type at the top of the page. Clicking on a country name will display the list of institutions in that country. This page functions in the same way as the institutional rankings page. Clicking on the number of articles on the Country rankings page displays a list of articles from that country with journal name, article title and corrected count. Hovering over the article title reveals the article DOI and clicking on the title opens the article on nature.com.
Rankings by journal
The rankings by journal list the number of papers published by each institution in each of the Nature family of research journals. As with the other rankings, the lists can be filtered according to article type using the article filter at the top of the page. By default, the top five institutions are listed for each journal. Clicking on ‘Show all’ lists all of the institutions from the Asia-Pacific that have affiliations associated with articles in that journal. Clicking on the number of articles displays a list of the relevant articles. The list contains the article title and corrected count.
Hovering over the article title reveals the article DOI and clicking on the title opens the article on nature.com.
Rankings by subject
The rankings by subject track institutions in the Asia-Pacific region in four subject areas: chemistry, earth & environment, life sciences and physical sciences. Click the tab at the top of the table to display the ranking for that subject.
The Historical rankings track data by country for primary research articles (reviews are not included) for past years. Clicking on the year at the top of the table will display the rankings for that year based on the corrected count. The number of articles is also listed.
These graphs provide a visual representation of the historical data based on primary research articles (reviews are not included) from past years.
Users can analyze data for either institutions or countries in the Asia-Pacific. Corrected count data is displayed by default, and the number of articles can be shown by making the appropriate selection.
The Latest research published in the past month in Nature journals from the Asia-Pacific region can be viewed by country. The lists show the journal name and article title. Clicking on the article title reveals a panel with article type, publish date, DOI, the affiliated institutions from the Asia-Pacific and the corresponding corrected count for each institution. Clicking on the "Full article" link opens the article on nature.com.
