The article presents the method in which the reform of the system of higher education and science in Poland in 2016–2018, constituted in the form of a framework act the “Constitution for Science” (known as Law 2.0). It was carried out, with particular emphasis on aspects of the transformation that remain in accordance with the postulates of the model of public co-management or, in relation to this model, remain in clear contradiction. The authors try to point out both the declared aspect of the processes constituting the reform as well as the actual realized dimension of those processes. Therefore, the research question that comes to the fore in the following investigations is: is it possible in the practice of public administration functioning in Poland to create regulatory solutions in line with contemporary achievements of science of administration and politics, such as the paradigm of public participation and the concept of public co-management.

Science at the state level consists of two distinct and heterogeneous systems: the global science system and national science systems. National science systems are deeply embedded in global science, and states seek to use global knowledge for domestic economic needs. However, harnessing the wealth of global knowledge can only be done through scientists. Consequently, the scientific strength of states in practice depends on the scientific strength of individual scientists. Their ability to collaborate internationally and to tap into the global scientific network is crucial. By remaining outside it and working within local research programs, the academic community risks being marginalized, losing the interest of national research funding patrons, and losing the ability to influence the development of science.

In this text, we analyze the limitations of using academic age as a proxy for biological age in the whole national science system, for which we consider both biological age and academic age of all researchers from all Polish universities, holding at least a PhD degree and participating in global academic science through international publications (N = 20 569). An approximation of a researcher's functioning in global science is having at least one publication indexed in the Scopus database in the analyzed decade 2009–2018. Thus, using the example of comprehensive data from the entire national system of science, we estimate the extent of limitations of using academic age as a proxy for biological age depending on selected independent variables and analyze both the practical and methodological implications of using academic age in academic career research, which is one of the most important components of quantitative studies of science.

In this paper we analyze the phenomenon of quitting academic science and show how quitting differs between men and women, academic disciplines and over time. The approach presented is comprehensive: global, based on cohorts of scientists, and longitudinal – we observe the publication activity of individual scientists over time. Using metadata from Scopus, a global bibliometric database of publications and citations, we analyze the publication careers of scientists from 38 OECD countries who began publishing in 2000 ( N = 142 776) and 2010 ( N = 232 843). The paper tests the usefulness of large bibliometric datasets for a global analysis of academic careers.
