Hybrid open access journals generally authorize self-archiving along with Author-pays model. Given the dependence of the Author-pays model on APCs paid by authors, it is expected to have a negative association with the free-of-charge Green model. By exploring a sample of 52,150 papers published in 47 Elsevier's hybrid journals, the study compares the OA models' citation performances to non-open access (NOA) model's and investigates the relationship between the quantities of their papers.Three OA groups are identified, including Green-only, APC-only and Green-APC. The OA papers show a citation advantage over the NOA articles, despite their lower number. The mixed APC-Green, gains the highest citation compared to the three other access models. However, the number of Green and APC-funded papers are revealed to have a negative association. Although, the combination of the Green and APC models magnifies the impact of OA papers, the inverse association between the quantities of their papers signifies that the lower number of the latter can be partially explained by the prevalence of the former. The results help academic librarians involved in advocating and managing OA to better understand authors' behaviors towards OA models and adopt a more supportive role for OA according to their preferences. 相似文献

In this article, we present an overview of a self-archiving service for the Brazilian Digital Library of Computing (BDBComp) and describe a user experiment conducted to evaluate it. This experiment involved several potential real users, including computer science graduate students and professors, and archivists/librarians. The results of this study and their implications for similar services are described and analyzed, following sound statistical principles, which can serve as a basis for other similar studies. These results and their analysis indicate that we have successed in building a usable, efficient and learnable self-archiving service, properties which are essential to bring users to the system. 相似文献

本文将循证政策方法引入到开放存取政策制定中,通过系统收集开放存取领域的相关证据,对其进行分级与分类,以此为依据,对是否制定开放存取政策,政策是自愿还是强制,以及开放存取的实现方式这三个关键的结构性问题进行证据综合。在此基础上,考虑中国的情境,初步得出我国开放存取政策的思路与框架:①制定国家层面的受公共资助研究成果的开放存取政策,并采取自顶而下的途径;②制定强制性的以自存档为主导的开放存取政策,并制定相应的惩罚性措施。本文展示了循证政策方法应用于开放存取政策制定的可行性,以及进一步深入利用的可能。图1。表2。参考文献28。 相似文献
