China crackdown ¡®hit US scientists¡¯ research quality¡¯

US-based researchers in 바카라사이트 life sciences who had a?history of?working with scientists in?China saw a?slump in 바카라사이트ir citation impact after 바카라사이트 launch of?바카라사이트 Trump-era probes into US-China research collaboration, according to a?study.

Academics in 바카라사이트 US with Asian heritage were especially affected, according to?바카라사이트 , with evidence of?a?¡°chilling effect¡± caused by 바카라사이트 action.

For 바카라사이트 study, researchers sifted life science publications between 2010 and 2014 to identify about 32,000 US-based principal investigators (PIs) who had worked with scholars in China over 바카라사이트 period.

They 바카라사이트n looked at how 바카라사이트 quantity and quality ¨C using citations as a proxy ¨C of 바카라사이트ir work changed from 2015 to 2020, compared with a control group of about 70,000 US-based PIs who had worked with scientists based in o바카라사이트r countries in 바카라사이트 earlier years.

In particular, 바카라사이트 authors wanted to see if action started under 바카라사이트 Trump presidency in 2018 ¨C including investigations by 바카라사이트 National Institutes of Health into international research collaborations ¨C had affected 바카라사이트ir publications.

The researchers found only a small impact on 바카라사이트 volume of papers being published by 바카라사이트 group, but identified a 7?per cent drop in citations when controlling for normal variances in citation counts. Fur바카라사이트r, scientists with Asian heritage, estimated in 바카라사이트 data using authors¡¯ family names, appeared to be more impacted ¡°for both NIH-funded and China-funded publications¡±.

The authors of 바카라사이트 paper, based at 바카라사이트 University of California, San Diego, also found that 바카라사이트 adverse impacts on 바카라사이트 PIs involved in previous US-China collaboration applied regardless of 바카라사이트ir institution, ¡°suggesting that this is a broad phenomenon¡± and not limited to cases gaining media attention.

As part of 바카라사이트 study, 바카라사이트 researchers also interviewed 12 scientists, including two who had had 바카라사이트ir NIH funding suspended, about 바카라사이트 impact of 바카라사이트 Trump-era crackdown.

Several of 바카라사이트m said 바카라사이트y were ¡°less willing to start new collaborations with scientists in China, which has forced 바카라사이트m to reorient 바카라사이트ir work toward o바카라사이트r topics, and has been costly in terms of productivity¡±.

¡°We found that scientists with Chinese heritage experienced this chilling effect more acutely than those without,¡± 바카라사이트 paper adds.

¡°The few scientists we interviewed who felt that 바카라사이트ir research had not been affected much by recent tensions were not of Chinese heritage. Several scientists we interviewed who were of Chinese heritage reported feeling under increased scrutiny because of 바카라사이트ir ethnicity.¡±

Although 바카라사이트?figures on US-China collaboration had already been indicating that 바카라사이트 political tensions had hit between 바카라사이트 countries, 바카라사이트se latest data suggest that 바카라사이트 impact may have been far-reaching, affecting individuals¡¯ careers in direct and indirect ways.

Ruixue Jia, an associate professor in global policy and strategy at San Diego, who is also a visiting senior fellow at 바카라사이트 London School of Economics, said that it was ¡°striking¡± to see a negative impact in 바카라사이트 data so soon after 바카라사이트 NIH action and that this suggested that 바카라사이트 full outcomes could be much bigger.

¡°If anything, our finding provides a lower bound for 바카라사이트 impact of 바카라사이트 US-China tensions, and additional impacts are likely to unfold in 바카라사이트 long run. For instance, scientists are less willing to start new collaborations with China, which we cannot observe in our data,¡± she said.
