Abstract

We approach productivity in science in a longitudinal fashion: We track scientists’ careers over time, up to 40 years. We first allocate scientists to decile-based publishing productivity classes, from the bottom 10% to the top 10%. Then, we seek patterns of mobility between the classes in two career stages: assistant professorship and associate professorship. Our findings confirm that radically changing publishing productivity levels (upward or downward) almost never happens. Scientists with a very weak past track record in publications emerge as having marginal chances of becoming scientists with a very strong future track record across all science, technology, engineering, mathematics, and medicine (STEMM) fields. Hence, our research shows a long-term character of careers in science, with one’s publishing productivity during the apprenticeship period of assistant professorship heavily influencing productivity during the more independent period of associate professorship. We use individual-level microdata on academic careers (from a national registry of scientists) and individual-level metadata on publications (from the Scopus raw dataset). Polish associate professors tend to be stuck in their productivity classes for years: High performers tend to remain high performers, and low performers tend to remain low performers over their careers. Logistic regression analysis powerfully supports our two-dimensional results. We examine all internationally visible Polish associate professors in five fields of science in STEMM fields (N = 4,165 with Nart = 71,841 articles).

科学家在学术阶梯上更上一层楼时,是否会改变他们的研究生产力等级?
我们以纵向方式研究科学的生产力:我们追踪科学家长达 40 年的职业生涯。我们首先将科学家划分为十等分的出版生产力等级,从最低的 10%到最高的 10%。然后,我们在两个职业阶段--助理教授和副教授--寻找不同等级之间的流动模式。我们的研究结果证实,从根本上改变出版生产力水平(向上或向下)的情况几乎从未发生过。在所有科学、技术、工程、数学和医学(STEMM)领域,过去发表论文记录非常薄弱的科学家成为未来发表论文记录非常出色的科学家的机会微乎其微。因此,我们的研究表明,科学职业具有长期性,一个人在助理教授学徒期的发表论文效率会严重影响其在更独立的副教授期的发表论文效率。我们使用了个人层面的学术生涯微观数据(来自全国科学家登记处)和个人层面的论文元数据(来自 Scopus 原始数据集)。波兰的副教授往往在其生产力等级中停留多年:在他们的职业生涯中,高绩效者往往一直是高绩效者,而低绩效者往往一直是低绩效者。逻辑回归分析有力地支持了我们的二维结果。我们研究了波兰在 STEMM 领域五个科学领域的所有国际知名副教授(N=4,165,Nart=71,841 篇文章)。

期刊介绍: Innovative Higher Education is a refereed scholarly journal that strives to package fresh ideas in higher education in a straightforward and readable fashion. The four main purposes of Innovative Higher Education are: (1) to present descriptions and evaluations of current innovations and provocative new ideas with relevance for action beyond the immediate context in higher education; (2) to focus on the effect of such innovations on teaching and students; (3) to be open to diverse forms of scholarship and research methods by maintaining flexibility in the selection of topics deemed appropriate for the journal; and (4) to strike a balance between practice and theory by presenting manuscripts in a readable and scholarly manner to both faculty and administrators in the academic community.
