New research demonstrates more effective method for measuring impact of scientific publications

2023-11-20
(Press-News.org) Newly published research reexamines the evaluation of scientific findings, proposing a network-based methodology for contextualizing a publication’s impact.

This new method, which is laid out in an article co-authored by Alex Gates, an assistant professor with the University of Virginia’s School of Data Science, will allow the scientific community to more fairly measure the impact of interdisciplinary scientific discoveries across different fields and time periods. The article was published by the Proceedings of the National Academy of Sciences, a journal of the National Academy of Sciences. 

The impact of a scientific publication has long been quantified by citation count. However, this approach is vulnerable to variations in citation practices, limiting the ability of researchers to accurately appraise the true importance of a scientific achievement. 

Recognizing this shortcoming, Gates and his co-authors – Qing Ke of the School of Data Science at City University of Hong Kong and Albert-László Barabási of Northeastern University – propose a network-normalized impact measure. By normalizing citation counts, their approach will help the scientific community avoid biases when assessing a diverse body of scientific findings -- both going forward and retrospectively.

In addition to the published findings, the authors have also implemented the method in an open-source package where anyone who is interested can find instructions on how to try this approach themselves on different examples of scientific research.

Gates joined UVA’s School of Data Science in 2022.

UCSB scientists will eliminate bottlenecks to breakthroughs with a newly acquired synthetic biology robotics system

2023-11-20
Researchers in UC Santa Barbara’s newly designated Biological Engineering (BioE) Department have received a significant boost from the U.S. Army, which awarded the university a $9.85 million grant to design and purchase state-of-the-art equipment that project leader Michelle O’Malley, a professor of chemical engineering and biological engineering, says “allows UCSB scientists to do things that we never thought were possible.” The funding, awarded through the Department of Defense’s Defense University Research ...

NASA’s Webb reveals new features in heart of Milky Way

NASA’s Webb reveals new features in heart of Milky Way
2023-11-20
The latest image from NASA’s James Webb Space Telescope shows a portion of the dense center of our galaxy in unprecedented detail, including never-before-seen features astronomers have yet to explain. The star-forming region, named Sagittarius C (Sgr C), is about 300 light-years from the Milky Way’s central supermassive black hole, Sagittarius A*. “There’s never been any infrared data on this region with the level of resolution and sensitivity we get with Webb, so we are seeing lots of features here for the first time,” said the observation team’s principal investigator Samuel Crowe, an undergraduate student at the University ...

UC Irvine-led study is first to find brain hemorrhage cause other than injured blood vessels

2023-11-20
Irvine, Calif., Nov. 20, 2023 — A first-of-its-kind study led by the University of California, Irvine has revealed a new culprit in the formation of brain hemorrhages that does not involve injury to the blood vessels, as previously believed. Researchers discovered that interactions between aged red blood cells and brain capillaries can lead to cerebral microbleeds, offering deeper insights into how they occur and identifying potential new therapeutic targets for treatment and prevention.   The ...

People watched other people shake boxes for science. Here’s why

People watched other people shake boxes for science. Here’s why
2023-11-20
When researchers asked hundreds of people to watch other people shake boxes, it took just seconds for almost all of them to figure out what the shaking was for. The deceptively simple work by Johns Hopkins University perception researchers is the first to demonstrate that people can tell what others are trying to learn just by watching their actions. Published today in the journal Proceedings of the National Academy of Sciences, the study reveals a key yet neglected aspect of human cognition, and one with implications for artificial intelligence. “Just by looking ...

AI finds formula on how to predict monster waves

AI finds formula on how to predict monster waves
2023-11-20
Long considered myth, freakishly large rogue waves are very real and can split apart ships and even damage oil rigs. Using 700 years’ worth of wave data from more than a billion waves, scientists at the University of Copenhagen and University of Victoria have used artificial intelligence to find a formula for how to predict the occurrence of these maritime monsters. The new knowledge can make shipping safer. EMBARGOED CONTENT UNTIL MONDAY 20 NOVEMBER 2023 3 PM US EASTERN TIME Stories about monster waves, called rogue waves, have been the lore of sailors for centuries. But when a 26-metre-high rogue wave slammed into the Norwegian oil ...

Study reveals bias in AI tools when diagnosing women’s health issue

2023-11-20
Machine learning algorithms designed to diagnose a common infection that affects women showed a diagnostic bias among ethnic groups, University of Florida researchers found.  While artificial intelligence tools offer great potential for improving health care delivery, practitioners and scientists warn of their risk for perpetuating racial inequities. Published Friday in the Nature journal Digital Medicine, this is the first paper to evaluate fairness among these tools in connection to a women’s health issue. “Machine learning can be a great tool in medical diagnostics, but we found it can show bias toward different ethnic groups,” said Ruogu Fang, an associate ...

Anti-bias police training improved performance and reduced discrimination-based complaints significantly

2023-11-20
In recent years, many police departments have mandated or encouraged anti-bias training. This has occurred in response to government-imposed measures such as consent decrees or as a proactive attempt to enhance public perceptions of police following actions that have raised concerns about racially motivated and other discriminatory practices. In a new study, researchers evaluated the effectiveness of an anti-bias training intervention in one Californian jurisdiction. The study found that officers who received the training had improved performance scores (measured by Body Worn Camera footage), decreased disparity in how they treated different groups of people, ...

Analysis of cyberstalking research identifies factors associated with perpetration, victimization

2023-11-20
The widespread use of digital technologies and the Internet has spurred a new type of personal intrusion, known as cyberstalking. Incidences of cyberstalking have risen, with the U.S. Department of Justice estimating that more than 1.3 million people experience this type of victimization annually. A new study explored research to identify the factors associated with perpetration and victimization in cyberstalking. The study’s findings can inform the development of efforts to prevent and address cyberstalking. Conducted by a researcher at Sam Houston State ...

Massive 2022 eruption reduced ozone levels

2023-11-20
When the Hunga Tonga-Hunga Ha’apai volcano erupted on January 15, 2022 in the South Pacific, it produced a shock wave felt around the world and triggered tsunamis in Tonga, Fiji, New Zealand, Japan, Chile, Peru and the United States. It also changed the chemistry and dynamics of the stratosphere in the year following the eruption, leading to unprecedented losses in the ozone layer of up to 7% over large areas of the Southern Hemisphere, according to a recent study published in the Proceedings of the National ...
