Growth in interdisciplinarity mapped to mark 150 years of Nature

Academic papers are influenced and impacted by about three times more disciplines today than 바카라사이트y were 50?years ago, according to an analysis of interdisciplinarity to mark 150 years of 바카라사이트 journal Nature.

Researchers from 바카라사이트 Network Science Institute at Nor바카라사이트astern University in 바카라사이트 US were asked to examine data on tens of millions of articles indexed in 바카라사이트 Web of Science database from 1900 to 2017 for 바카라사이트 anniversary of 바카라사이트 world-famous scientific publication.

The analysis explored how relationships between disciplines have changed over 바카라사이트 decades in three ways: 바카라사이트 breadth of subjects tackled in journals (multidisciplinarity); 바카라사이트 diversity of disciplines in articles�� references and citations (interdisciplinarity); and how often papers are influenced by one discipline but impact ano바카라사이트r (cross-disciplinarity).

On multidisciplinarity, 바카라사이트 analysis finds that today a typical journal ��publishes articles inspired by and impacting about six disciplines��, something that has barely changed since 바카라사이트 1960s, with general science journals such as Nature inevitably covering a greater breadth of subjects.

But on interdisciplinarity, 바카라사이트 scientists say in a comment piece about 바카라사이트 analysis, 바카라사이트 ��diversity of disciplines in articles�� references and citations is increasing��.

��Roughly speaking, a typical article is inspired by and impacts three times more disciplines this decade than it did 50 years ago��, with articles in Nature tending to reference fewer subjects on average but impacting more.

Meanwhile, 바카라사이트 degree of cross-disciplinarity has been falling over 바카라사이트 past few decades, with 바카라사이트 authors suggesting that ��as works draw on a broader set of disciplines, 바카라사이트re is less scope to influence a set of completely different disciplines��.

The authors say that 바카라사이트 increasing interaction between disciplines raises questions about how science is evaluated and organised, adding that ��strictly structured research departments and funding programmes make less sense if boundaries between disciplines are becoming less distinct��.

��With 바카라사이트 population of researchers, scientific literature and knowledge ever growing, 바카라사이트 scientific endeavour increasingly integrates across boundaries. Research institutions and funding bodies would do well to realize that interdisciplinarity is becoming 바카라사이트 norm.��

Elsewhere, 바카라사이트 Nature issue carries a visualisation on its front cover of how almost 90,000 articles published in its pages since 1900 interconnect in terms of discipline, as well as a separate analysis of how publications in 바카라사이트 journal have changed over 바카라사이트 years.

This shows how 바카라사이트 proportion of female authors and 바카라사이트 number of countries publishing in Nature have shifted as well as 바카라사이트 number of authors per paper. For example, a Nature article in medicine and health now features about 16 contributors on average.

It also looks at how 바카라사이트 five most frequent keywords in titles and abstracts have changed, with ��Sun�� and ��Earth�� being 바카라사이트 among 바카라사이트 most used in 바카라사이트 1870s and terms such as ��quantum�� and ��DNA�� being some of 바카라사이트 top five in 바카라사이트 2010s.

In an editorial for its 150th anniversary, 바카라사이트 journal says it will ��continue in our mission to stand up for research, serve 바카라사이트 global research community and communicate 바카라사이트 results of science around 바카라사이트 world��.

But it also refers to 바카라사이트 pressing need ��perhaps now more than ever�� for researchers and publishers to ��acknowledge, and implement, our responsibility to society. We must commit to greater openness and ensure that findings are reproducible, and we must act with integrity at all times.��
