Survivability is one of the features for success in contemporary science ecosystem. In this paper, we analyze the publication records of physicists in American Physical Society journals, aiming to identify the career length of each researcher and accordingly investigate the dropout phenomenon in science by the example of physicists. We find that scientific career is a complex nonlinear evolution process and can be generally divided into four stages regarding the dropout rate. In the early career, the dropout rate from trainee phase to maturity is high and negatively correlated with the research performance of the scientists, in both productivity and impact. Moreover, a strong nonlinearity is observed when we study the detailed relationship between the dropout rate and research performance. Interestingly, in the more mature stage of the career, the dropout rate becomes stable and independent of the early performance of the scientists. In the late career stage, the dropout rate increases and is mainly determined by retirement and external factors. The findings in this paper may provide useful guidance for young scholars to allocate their research effort in the early career.

Contemporary science has been characterized by an exponential growth in publications and a rise of team science. At the same time, there has been an increase in the number of awarded PhD degrees, which has not been accompanied by a similar expansion in the number of academic positions. In such a competitive environment, an important measure of academic success is the ability to maintain a long active career in science. In this paper, we study workforce trends in three scientific disciplines over...

In areas of human activity where performance is difficult to quantify in an objective fashion, reputation and networks of influence play a key role in determining access to resources and rewards. To understand the role of these factors, we reconstructed the exhibition history of half a million artists, mapping out the coexhibition network that captures the movement of art between institutions. Centrality within this network captured institutional prestige, allowing us to explore the career traje...

While research on adolescent occupational expectations is voluminous, it either ignores students who do not report any career plans or imputes their answers. Consequently, little is known about the potential consequences that not having clear occupational expectations in adolescence might have for educational and occupational attainment in young adulthood. Therefore, this article presents evidence from the Longitudinal Survey of Australian Youth (LSAY), which followed students between 2006 and 2...

BACKGROUND The increasing availability of digital data on scholarly inputs and outputs—from research funding, productivity, and collaboration to paper citations and scientist mobility—offers unprecedented opportunities to explore the structure and evolution of science. The science of science (SciSci) offers a quantitative understanding of the interactions among scientific agents across diverse geographic and temporal scales: It provides insights into the conditions underlying creativity and the ...

Objectives To explore the factors that influence career progress for early stage clinician-scientists and to identify ways to mitigate these factors in the context of emerging Asian academic medical centres (AMCs). Design Qualitative interviews and thematic data analysis based on grounded theory. Setting and participants Five focus group interviews comprising 29 early career clinician-scientists who have received their first national-level career development award in Singapore. Results Clinical ...

Abstract The science of science (SOS) is a rapidly developing field which aims to understand, quantify and predict scientific research and the resulting outcomes. The problem is essentially related to almost all scientific disciplines and thus has attracted attention of scholars from different backgrounds. Progress on SOS will lead to better solutions for many challenging issues, ranging from the selection of candidate faculty members by a university to the development of research fields to whic...

Research policy observers are increasingly concerned about the potential impact of current academic working conditions on mental health, particularly in PhD students. The aim of the current study is threefold. First, we assess the prevalence of mental health problems in a representative sample of PhD students in Flanders, Belgium (N = 3659). Second, we compare PhD students to three other samples: (1) highly educated in the general population (N = 769); (2) highly educated employees (N = 592); an...

Are there quantifiable patterns behind a successful scientific career? Sinatra et al. analyzed the publications of 2887 physicists, as well as data on scientists publishing in a variety of fields. When productivity (which is usually greatest early in the scientist's professional life) is accounted for, the paper with the greatest impact occurs randomly in a scientist's career. However, the process of generating a high-impact paper is not an entirely random one. The authors developed a quantitati...

This study investigated the extent to which tolerance of uncertainty affects the relationship between happenstance skills and career satisfaction via career decision self-efficacy. Moderated mediation analysis was conducted on data collected from 321 graduates (175 men, 146 women) of Korean universities making the school-to-work transition. Results showed that career decision self-efficacy fully mediated the relationship between happenstance skills and career satisfaction. Furthermore, the moder...
