我们引入一个指标来衡量科学研究的扩散。与斯特林的3因素多样性模型一致,扩散分数不仅捕捉到多样性和平衡,而且还捕捉到引用文章队列之间的差异。我们将其应用于基准文章样本从1995年Web的科学主题类别(SC)跟踪知识扩散的趋势,随着时间的推移,因为出版。研究结果表明,对于大多数SC,扩散分数随着时间的推移稳步增加。数学是一个局外人。我们采用了一种类型学的引用趋势之间的基准SC和相关的扩散分数。我们还发现,自我引用不,在大多数情况下,显着影响扩散分数。
We introduce an indicator to measure the diffusion of scientific research. Consistent with Stirling's 3-factor diversity model, the diffusion score captures not only variety and balance, but also disparity among citing article cohorts. We apply it to benchmark article samples from six 1995 Web of Science subject categories (SCs) to trace trends in knowledge diffusion over time since publication. Findings indicate that, for most SCs, diffusion scores steadily increase with time. Mathematics is an outlier. We employ a typology of citation trends among benchmark SCs and correlate this with diffusion scores. We also find that self-cites do not, in most cases, significantly influence diffusion scores.
