Is the Year of First Publication a Good Proxy of Scholars' Academic Age?

  title={Is the Year of First Publication a Good Proxy of Scholars' Academic Age?},
  author={Rodrigo Costas and Tina Nane and Vincent Larivi{\`e}re},
Individual scholars are the central unit of the research system and are increasingly the focus of bibliometric studies. An important aspect in the study of individual scholars is their academic age, which allows for the comparison of scholars that have been academically active in a similar period of time. Based on a sample of Quebec researchers for whom their year of birth, PhD year as well as the year of their first publication are known, we study the relationships among these ages with the…

Academic vs. Biological Age in Research on Academic Careers: A Large-scale Study with Implications for Scientifically Developing Systems

It is suggested that in scientifically developing countries, academic age as a proxy for biological age must be used more cautiously than in advanced countries: ideally, it must be use only for STEMM disciplines.

Domestic researchers with longer careers generate higher average citation impact but it does not increase over time

Abstract Information about the relative strengths of scholars is needed for the efficient running of knowledge systems. Because academic research requires many skills, more experienced researchers

Understanding success through the diversity of collaborators and the milestone of career

The results show that collaborating with authoritative authors plays an important role prior to a researcher's PhD graduation, but working with non‐authoritative authors carries more weight after PhD graduation.

How does research productivity relate to gender? Analyzing gender differences for multiple publication dimensions

It is found that women do research and write manuscripts, but may have different publication patterns: instead of submitting to competitive journals, they may be satisfied with less-prestigious book chapters, which may be disadvantageous for women.

Tracing scientific mobility of Early Career Researchers in Spain and The Netherlands through their publications

More sophisticated bibliometric analyses and comparisons with different 'generations' of researchers, possibly combined with qualitative investigation, will be required to better understand the role and function of national institutional context in both research mobility and research careers.

Scholars on Twitter: who and how many are they?

By combining bibliometric data from Web of Science and Twitter users identified by this http URL, this paper has obtained the largest set of individual scholars matched with Twitter users made so far, and finds a strong presence of researchers from the Social Sciences and the Humanities.

Star inventors and gender gaps in patented innovations

It is found that women are underrepresented among the overall pool of inventors, but less so among stars, and on the contrary, there seems to be a female advantage among top innovators, probably driven by selection effects.

Contributorship and division of labor in knowledge production

It is shown that scientific work is more highly divided in medical disciplines than in mathematics, physics, and disciplines of the social sciences, and that, with the exception of medicine, the writing of the paper is the task most often associated with authorship.

Modelling citation performance of Canadian researchers using Bayesian Networks

CBN and NPBN models perform similar to linear regression models in predicting citation performance of Canadian researchers, however, none of the Bayesian networks andlinear regression models fit perfectly, as they all have violations of their model assumptions.

Large-scale identification and characterization of scholars on Twitter

A new method for identifying scholars who have a Twitter account from bibliometric data from Web of Science (WoS) and Twitter data from Altmetric.com is presented, which reliably identifies matches between Twitter accounts and scholarly authors.



The Effects of Aging on Researchers' Publication and Citation Patterns

Drawing on a sizeable sample of 6,388 university professors in Quebec who have published at least one paper between 2000 and 2007, the results identify two turning points in the professors' careers, showing clearly that productivity and impact are not a simple and declining function of age and that they must take into account the collaborative aspects of scientific research.

Analysis of bibliometric indicators for individual scholars in a large data set

This work analyzes the scientific profile of more than 30,000 researchers, and finds that the h-index of a scientist is strongly correlated with the number of citations that she/he has received so that theNumber of citations can be effectively be used as a proxy of theh-index.

Do age and professional rank influence the order of authorship in scientific publications? Some evidence from a micro-level perspective

There is a strong trend for signatures of younger researchers and those in the lower professional ranks to appear in the first position, while more veteran or highly-ranked ones, who tend to play supervisory functions in research, are proportionally more likely to sign in the last position.

Productivity, impact and publication habits by gender in the area of Materials Science

A different life-cycle of productivity is found for men and woman and the most important inter-gender differences in productivity occur at the ages of 40-59.

A bibliometric approach to tracking international scientific migration

It is concluded that the bibliometric approach is promising provided that its outcomes are interpreted with care, based on insight into the limits and potentialities of the approach, and combined with complementary data, obtained, for instance, from researchers’ Curricula Vitae o, survey or questionnaire- based data.

Long-term variations in the aging of scientific literature: From exponential growth to steady-state science (1900-2004)

The major finding of this article is that contrary to a widely held belief, the age of cited material has risen continuously since the mid1960s, and it is suggested that this phenomenon is a direct response to the steady-state dynamics of modern science that followed its exponential growth.

The skewness of scientific productivity

International temporary mobility of researchers: a cross-discipline study

The extent to which information obtained from researchers’ electronic curriculum vitae (CV) may be used to study temporary geographical mobility is explored, exploiting a new type of data set—a comprehensive database of electronic CVs— developing a broad set of cross-discipline mobility indicators to assess the dimensions and characteristics of international research visits among a population of over 10,000 researchers.

Age and research productivity of academic scientists

Age-publishing profiles are estimated for four fields of science using data from the 1977 Survey of Doctorate Recipients. The five measures of publishing activity used allow for analysis of the

At what age do biomedical scientists do their best work?

High‐quality scientific productivity in the biomedical fields as a function of investigator's age plots an inverted U‐shaped curve, in which significant decreases take place from around 40 yr of age and beyond.
