AbstractInterdisciplinary research is of significance for creating breakthroughs and facilitating innovations and may achieve higher citation impact, although contrary results still exist. The current study looks into the relationship between interdisciplinarity and citation impact from a brand-new perspective—the process of citation accumulation—by exploring how interdisciplinarity, as measured by Rao-Stirling and DIV, affects the accumulating process of citations, based on scientific papers published by Chinese or US authors in 2009–2011 in Chemistry. Two metrics are used to measure how long it takes for a paper to reach its citation peak (PEAK_YEAR) and how sustainable the citation impact remains after the peak (SUS). The results show that compared with Rao-Stirling, DIV is more sensitive to the length of the citation window and more closely aligned with the nature of interdisciplinarity. In Chemistry, higher interdisciplinarity is more likely to encounter delayed recognition and greater citation sustainability, which may explain the inconsistency in the relationship between interdisciplinarity and citation impact. In conclusion, it is necessary to consider the length of the citation window when explaining the relationship between interdisciplinarity and citation impact. A longer citation window may be a better solution, as an alternative or supplement, in assessing the academic performance of interdisciplinary research.

Background: The substandard vaccine case of that broke out in July 2018 in China triggered an outburst of news reports both domestically and aboard. Distilling the abundant textual information is helpful for a better understanding of the character during this public event. Methods: We collected the texts of 2211 news reports from 83 mainstream media outlets in China between 15 July and 25 August 2018, and used a structural topic model (STM) to identify the major topics and features that emerged. We also used dictionary-based sentiment analysis to uncover the sentiments expressed by the topics as well as their temporal variations. Results: The main topics of the news report fell into six major categories, including: (1) Media Investigation, (2) Response from the Top Authority, (3) Government Action, (4) Knowledge Dissemination, (5) Finance Related and (6) Commentary. The topic prevalence shifted during different stages of the events, illustrating the actions by the government. Sentiments generally spanned from negative to positive, but varied according to different topics. Conclusion: The characteristics of news reports on vaccines are shaped by various topics at different stages. The inner dynamics of the topic and its alterations are driven by the interaction between social sentiment and governmental intervention.
