The utilization of accolade awards to motivate reviewers is widespread, but their effectiveness remains uncertain. We aim to explore how receiving an accolade award affects reviewers’ subsequent number of reviews. In contrast to small-scale, unrepresentative experiments, we perform a large-scale, global, and all-disciplinary analysis based on quasi-natural experiments. By integrating the Publons, ORCID, MAG, SciSciNet, and OpenAlex databases, a large dataset that tracks the reviewers’ annual number of reviews and their bibliometric indicators is compiled, encompassing 179,794 individuals. Among them, 6605 individuals who receive the “Publons Global Peer Review Award” in 2018 are constituted as the experimental group. Those non-winners are then matched to form a control group. Using propensity score matching (PSM), 711 and 762 reviewers are matched as the experimental and control groups respectively. An analysis employing the difference-in-differences (DiD) method is conducted to examine the impact of an accolade award on reviewers’ subsequent number of reviews. It is found that, following the receipt of an accolade award, reviewers, on average, reviews about four fewer manuscripts, with the reduction exhibiting a V-shaped pattern. Additional analyses are conducted to examine how individual differences and socio-economic factors influence the awarding effects. Besides, we analyze the mechanisms underlying the awarding effect and propose strategies to motivate reviewers. In brief, the sharp decrease in marginal utility of accolades, the voluntary nature of peer review, and the unexpected properties of accolade awards are the potential mechanisms that generate the negative effect. The academic community should reassess the existing incentive strategies for reviewers.

Background: The new media provides a convenient platform to access, use and exchange health information. And as a special group of health care, maternal health care is still of international concern due to their high mortality rate. Scientific research is a good way to provide advice on how to improve maternal health through stringent reasoning and accurate data. However, the dramatic increase of publications, the diversity of themes, and the dispersion of researchers may reduce the quality of information and increase the difficulty of selection. Thus, this study aims to analyze the research progress on maternal health under the global new media environment, exploring the current research hotspots and frontiers. Methods: A scientometric analysis was carried out by CiteSpace5.7.R1. In total, 2270 articles have been further analyzed to explore top countries and institutions, potential articles, research frontiers, and hotspots. Results: The publications ascended markedly, from 29 in 2008 to 472 publications by 2020. But there is still a lot of room to grow, and the growth rate does not conform to the Price’s Law. Research centers concentrated in Latin America, such as the University of Toronto and the University of California. The work of Larsson M, Lagan BM and Tiedje L had high potential influence. Most of the research subjects were maternal and newborn babies, and the research frontiers were distributed in health education and psychological problems. Maternal mental health, nutrition, weight, production technology, and equipment were seemingly hotspots. Conclusion: The new media has almost brought a new era for maternal health, mainly characterized by psychological qualities, healthy and reasonable physical conditions and advanced technology.

Predicting breakthrough papers holds great significance; however, prior studies encountered challenges in this task, indicating a need for substantial improvement. We propose that the failure to capture the dynamic structural-evolutionary features of citation networks is one of the major reasons. To overcome this limitation, this paper introduces a new method for constructing citation cascades of focus papers, allowing the creation of a time-series-like set of citation cascades. Then, through a thorough review, three types of structural indicators in these citation networks that could reflect breakthroughs are identified, including certain basic topological metrics, PageRank values, and the von Neumann graph entropy. Based on the time-series-like set of citation cascades, the dynamic trajectories of these indicators are calculated and employed as predictors. Using the Nobel Prize-winning papers as a landmark dataset, our prediction method yields approximately a 7% improvement in the ROC-AUC score compared to static-based prior methods. Additionally, our method advances in achieving earlier predictions than other previous methods. The main contribution of this paper is proposing a novel method for creating citation cascades in chronological order and confirming the significance of predicting breakthroughs from a dynamic structural perspective.

Background: The new media provides a convenient digital platform to access, use and exchange health information. As a special group of health care, maternal is still of international concern due to their high mortality rate. Improving maternal health as a Millennium Development Goal of the United Nations is an important quest for the health care system. Scientific research provides advice on how to improve maternal health through stringent reasoning and accurate data. However, the dramatic increase of publications, the diversity of themes, and the dispersion of researchers may reduce efficiency. Objective: This study aims to analyze the research progress on maternal health under the global new media environment, exploring the current research hotspots and research frontiers. Methods: A scientometric analysis was carried out by CiteSpace5.7.R1, searching in the core database of Web of Science for articles published in English from 1998 to 2021, and combined topic words such as new media, maternal, and health. In total, 3312 articles have been retrieved, of which 2270 studies have been included for further analysis. Top countries and institutions, potentially high-impact literature, research frontiers, and hotspots were analyzed in this study. Results: The number of publications grew rapidly after 2008, from 29 publications sharply increasing to 472 publications by 2020. Research centers concentrated in Latin America, such as the University of Toronto, the University of California. The work of Larsson M, Lagan BM, Tiedje L, and Helle C had a high potential impact. Most of the research subjects were maternal and newborn babies, and the research frontiers focused on health education and maternal psychological problems. Maternal mental health, maternal and infant nutrition, weight, production technology, and equipment were hotspots. Conclusion: The development of new media has brought a new era for maternal health, characterized by psychological qualities, healthy and reasonable physical conditions, and advanced technology.

Drawing on data from the Korean Longitudinal Study of Aging (n = 3252) and the Chinese Longitudinal Healthy Longevity Survey (n = 8281) from 2008 to 2018, this study employed fixed-effects panel data regressions to examine the differential association between healthy lifestyles and disability across education, income, and place of residence. Our results indicate that adopting one more healthy lifestyle was associated with a 0.1–0.2 point lower disability score among older adults in South Korea (β = −0.14, 95% CI, −0.19 to −0.09) and China (β = −0.24, 95% CI, −0.28 to −0.21). Specifically, this association was more pronounced among older adults with higher income, lower education, and urban residents, with a significant difference based on the Chow test (P < 0.05). Clinical and public health policies could pay attention to reducing the socioeconomic disparities highlighted in this study through tailored interventions. Our findings suggest that promoting healthy lifestyles among less-educated individuals might yield significant benefits against disability. They underscore the potential of promoting healthy lifestyles to mitigate education-related inequalities in disability within aging societies. We recommend that policymakers consider simultaneously emphasizing the enhancement of health literacy to delay disability onset among vulnerable groups and prevent the risk of low-income households slipping back into poverty.
