由于学术迁移而形成的科学合作网络的动态

Dynamics of scientific collaboration networks due to academic migrations

Pavlos Paraskevopoulos, Chiara Boldrini, Andrea Passarella, Marco Conti

摘要:

学术移民是研究人员改变东道机构,通常旨在实现更强大的研究形象。科学特征,如合作的数量,生产力及其研究影响往往直接受到这种运动的影响。在本文中,我们分析了研究人员的合作网络的动态,因为他们从一个机构到下一个。我们特别强调了它们增加和收缩的情况,并量化了这种运动前后协作网络之间的依赖关系。最后,我们通过根据研究人员的职业阶段划分运动来深入分析。分析表明,跨迁移的协作网络具有显着的活力。有趣的是,移动并不总是会导致更大的协作网络,而移动网络之间的总体相似性平均来说非常有限。在所有职业生涯阶段都可以发现同样的影响,但显然,它们的大小可能有所不同。这些结果基于从Scopus中提取的数据集,其中包含84,141名研究人员的出版物的详细科学信息。

英文摘要:

Academic migration is the change of host institution by a researcher, typically aimed at achieving a stronger research profile. Scientific features such as the number of collaborations, the productivity and its research impact tend to be directly affected by such movements. In this paper, we analyse the dynamics of the collaboration network of researchers as they move from an institution to the next one. We specifically highlight cases where they increase and when they shrink, and quantify the dependency between the collaboration networks before and after such a movement. Finally, we drill down the analysis by dividing movements depending on the career stage of the researchers. The analysis shows a remarkable dynamism of collaboration networks across migrations. Interestingly, not always movements result in larger collaboration networks, while the overall similarity between networks across movements is quite limited on average. Qualitatively, the same effects can be found at all career stages, while, clearly, the magnitude of them might vary. These results are based on a dataset extracted from Scopus, containing detailed scientific information for the publications of 84,141 researchers.
