Abstract Journal ranking is becoming more important in assessing the quality of academic research. Several indices have been suggested for this purpose, typically on the basis of a citation graph between the journals. We follow an axiomatic approach and find an impossibility theorem: any self-consistent ranking method, which satisfies a natural monotonicity property, should depend on the level of aggregation. Our result presents a trade-off between two axiomatic properties and reveals a dilemma ...

Abstract In this article we solve a minimum problem involving step functions. The solution of this problem leads to an investigation into generalized h- and g-indices. This minimum problem and the related generalized h- and g-indices are studied in a general context of decreasing differentiable functions as well as in the specific case of Lotkaian informetrics. The study illustrates the use of h-and g-indices and their generalizations in a context which bears no relation to the research evaluati...

Abstract Twitter altmetrics has been proposed to measure the popularity and the potential societal impact of scientific products, but scientific tweeters who produce the Twitter altmetrics data have not been well explored. The study, by analyzing 2.63 million scientific tweeters’ data that are extracted from the company dataset, is aimed to reveal their productivity and geographic distribution in a comprehensive way. To gain a more in-depth understanding of their account types and ...

Abstract This study inserts in the stream of research on the perverse effects that PBRF systems can induce in the subjects evaluated. The authors’ opinion is that more often than not, it is the doubtful scientific basis of the evaluation criteria that leave room for opportunistic behaviors. The work examines the 2004–2010 Italian national research assessment (VQR) to test the lack of possible opportunistic behavior by universities in order to limit the penalization of their performance (and fund...

Abstract In this paper, we investigate the effects of using four methods of publication counting (complete, whole, fractional, square root fractional) and limiting the number of publications (at researcher and institution levels) on the results of a national research evaluation exercise across fields using Polish data. We use bibliographic information on 0.58 million publications from the 2013–2016 period. Our analysis reveals that the largest effects are in those fields within which a variety p...

Abstract This paper proposes two novel measures to study the geographic mobility of faculty members from their graduating institutions in the United States: a continuous measure using geographic distance and a discrete one concerning the concept of Metropolitan Statistical Area (MSA). The joint application of the two novel measures to a hand-collected hiring network dataset including more than 15,000 faculty members in three disparate disciplines (business, computer science, and history) leads t...

Abstract Constructing academic networks to explore intellectual structure realize academic community detection, which can promote scientific research innovation and discipline progress, constitutes an important research topic. In this study, tripartite citation is fused with co-citation and coupling relations as a way of weighting the strength of direct citations, and all-author tripartite citation networks were constructed due to the contributions of all authors to the resulting publications. F...
