Inconsistent quality signals: evidence from the regional journals.

Nowadays many countries and institutions use bibliometric assessment of journal quality in their research evaluation policies. However, bibliometric measures, such as impact factor or quartile, may provide a biased quality assessment for relatively new, regional, or non-mainstream journals, as these outlets usually do not possess a longstanding history, and may not be included into indexing databases. To reduce the information asymmetry between academic community (researchers, editors, policymakers) and journal management, we propose an alternative approach to evaluate journals quality signals using previous publication track record of authors. We explore the difference in the quality signals sent by regional journals. Traditional, journal-level, bibliometric measures are contrasted with generalised measures of authors' publishing records. We used a set of 50,477 articles and reviews in 83 regional journals in Physics and Astronomy (2014-2019) to extract and process data on 73 866 authors and their additional 329,245 publications in other Scopus-indexed journals. We found that traditional journal-level measures (such as journal quartile, CiteScore percentile, Scimago Journal Rank) tend to under-evaluate journal quality, thus contributing to an image of low-quality research venues. Author-level measures (including the share of papers in the Nature Index journals) send positive signals of journal quality and allow us to subdivide regional journals by their publishing strategies. These results suggest that research evaluation policies might consider attributing greater weight to regional journals, not only for the training purposes of doctoral students but also for gaining international visibility and impact.

The adaptation of academics to the Covid-19 crisis in terms of work time allocation.

Academics have seen their work environment and routines severely affected by the Covid19 pandemic. This topic has been analyzed by the literature, mostly from personal and descriptive perspectives, that highlight the challenging transitions and adaptations that academics have endured concerning their work and life-balance. This research complements those studies, by using a sample of university academics working all around the world in all disciplinary fields and focuses on a longitudinal perspective of workload and task time allocation of academic work. The findings show that academics which in general had long working hours, further increased their time of the week dedicated to work leading possibly to the reported cases in the literature of increasing stress and burnout during the pandemic. These effects were found to be similar to all academics, independently of their gender and disciplinary field. More concerning is that this increased number of hours worked per week appears to have established itself as part of the new normal. The main driver for the increased workload is associated with teaching, and to a lesser extent with administrative duties.

How academic achievement spreads: The role of distinct social networks in academic performance diffusion.

Behavior diffusion through social networks is a key social process. It may be guided by various factors such as network topology, type of propagated behavior, and the strength of network connections. In this paper, we claim that the type of social interactions is also an important ingredient of behavioral diffusion. We examine the spread of academic achievements of first-year undergraduate students through friendship and study assistance networks, applying stochastic actor-oriented modeling. We show that informal social connections transmit performance while instrumental connections do not. The results highlight the importance of friendship in educational environments and contribute to debates on the behavior spread in social networks.

The effects of prenatal testosterone on wages: Evidence from Russia.

Is in utero exposure to testosterone correlated with earnings? The question matters for understanding determinants of wage differences that have attracted so much attention among economists in the past decade. Evidence indicates that markers for early testosterone exposure are correlated with traits like risk-taking and aggressiveness. But it is not at all clear how such findings might map into labor market success. We combine unique data from the Russian Longitudinal Monitoring Survey with measured markers (2D:4D ratios) for testosterone exposure and find that lower digit ratios (higher T) correlate with higher wages for women and for men, when controlling for age, education and occupation. There is also some evidence of a potential non-linear, inverse U-effect of digit ratios on wages but this is sensitive to choice of specification. These findings are consistent with earlier work on prenatal T and success in careers (Coates et al., 2009) but inconsistent with the work of Gielen et al. (2016) who find differing effects for men and women.

2D:4D asymmetry and gender differences in academic performance.

Exposure to prenatal androgens affects both future behavior and life choices. However, there is still relatively limited evidence on its effects on academic performance. Moreover, the predicted effect of exposure to prenatal testosterone (T)-which is inversely correlated with the relative length of the second to fourth finger lengths (2D:4D)-would seem to have ambiguous effects on academic achievement since traits like aggressiveness or risk-taking are not uniformly positive for success in school. We provide the first evidence of a non-linear, quadratic, relationship between 2D:4D and academic achievement using samples from Moscow and Manila. We also find that there is a gender differentiated link between various measures of academic achievement and measured digit ratios. These effects are different depending on the field of study, choice of achievement measure, and use of the right hand or left digit ratios. The results seem to be asymmetric between Moscow and Manila where the right (left) hand generates inverted-U (U-shaped) curves in Moscow while the pattern for hands reverses in Manila. Drawing from unusually large and detailed samples of university students in two countries not studied in the digit literature, our work is the first to have a large cross country comparison that includes two groups with very different ethnic compositions.
