Researchers’ risk-smoothing publication strategies: Is productivity the enemy of impact?

Factors to Improve Publication Productivity in Russian Universities

One of the most important conditions for the effectiveness of science is the motivation of academic staff of universities as key and direct producers of new knowledge. The purpose of the article was to substantiate the factors of efficiency in managing the publication activity of Russian universities. The nature and density of the relationship between the number of scientific publications and the level of citation of 19 leading countries in the world, including Russia, were determined by means of statistical analysis and the method of clusters. It has been empirically proven that the priority model for the development of publication activity should be an intensive model, which aims at improving the quality of scientific publications and the level of their citation. Moreover, a survey of 1573 young scientists (under the age of 39) and 2461 senior scientists from 14 universities in Russia was conducted. It investigated the factors of effective management of the publication activity at Russian universities. The results contribute to a better understanding on how Russian universities can activate and foster the flow of high-quality publication outputs by their researchers.

All downhill from the PhD? The typical impact trajectory of U.S. academic careers

Within academia, mature researchers tend to be more senior, but do they also tend to write higher impact articles? This article assesses long-term publishing (16+ years) United States (U.S.) researchers, contrasting them with shorter-term publishing researchers (1, 6, or 10 years). A long-term U.S. researcher is operationalized as having a first Scopus-indexed journal article in exactly 2001 and one in 2016–2019, with U.S. main affiliations in their first and last articles. Researchers publishing in large teams (11+ authors) were excluded. The average field and year normalized citation impact of long- and shorter-term U.S. researchers’ journal articles decreases over time relative to the national average, with especially large falls for the last articles published, which may be at least partly due to a decline in self-citations. In many cases researchers start by publishing above U.S. average citation impact research and end by publishing below U.S. average citation impact research. Thus, research managers should not assume that senior researchers will usually write the highest impact papers.

The research trends of metal-organic frameworks in environmental science: a review based on bibliometric analysis

Metal-organic frameworks, an emerging class of porous material, have developed rapidly in recent years. In order to clarify the application of metal-organic frameworks in the field of environmental science, 1386 articles over the last 20 years were obtained from Scopus and analysed by the bibliometric method. And the collaboration between countries, institutions and authors and the co-occurrence of keywords were also conducted using VOSviewer. The results indicated that this area of research has entered a fast-developing stage. The number of articles published has grown from 7 articles in 1999 to 378 articles in 2018. The most productive country was China with 626 articles published. The most productive institution was the Chinese Academy of Sciences, and the most productive author was Jhung SH from Kyungpook National University of South Korea. Although metal-organic frameworks have been widely used in adsorption and catalytic degradation of pollutants from the environment, the removal mechanism of pollutants by MOFs, the stability improvement and the cost reduction of metal-organic frameworks are still the main challenges for their practical applications.
