This study analyzes the patterns of university co-authorship networks in the Guangdong-Hong Kong-Macau Greater Bay Area. It also examines the quality and subject distribution of co-authored articles within these networks. Social network analysis is used to outline the structure and evolution of the networks that have produced co-authored articles at universities in the Greater Bay Area from 2014 to 2018, at both regional and institutional levels. Field-weighted citation impact (FWCI) is used to analyze the quality and citation impact of co-authored articles in different subject fields. The findings of the study reveal that university co-authorship networks in the Greater Bay Area are still dispersed, and their disciplinary development is unbalanced. The study also finds that, while the research areas covered by high-quality co-authored articles fit the strategic needs of technological innovation and industrial distribution in the Greater Bay Area, high-quality research collaboration in the humanities and social sciences is insufficient.

The skies of Northern Chile are considered among the best in the world for astronomy due to their geographical, climatic and atmospheric conditions. In fact, during the last several decades, a great number of astronomical observatories have been built by space research institutions devoted to space research, turning Chile into one of the countries with the greatest astronomical observation capacity in the world. Consequently, it is relevant to explore and assess the development of astronomy in Chile during the last ten years (2005-2015), carrying out a bibliometric analysis to extract traditional metrics, complemented with alternative metrics, to identify the Chilean production and scientific contribution of research in this field of knowledge. The results from traditional metrics, based on the information obtained in the Web of Science (WoS) database analyzed through InCites for the Astronomy & Astrophysics category indicate a sustained increase of the scientific production for the discipline during the last ten years. In particular, the Normalized Citation Impact of organizations and institutions conducting research in Chile is above the worldwide average. On the other hand, the alternative metrics, including for instance, the altmetrics types presented by the SCOPUS database, reflect that the Chilean research impact is much lower in the context of social networks.

INTRODUCTION: To compare the surgical outcomes of anterior chamber (AC) and posterior chamber (PC) implantation of iris claw lens (ICL) combined with penetrating corneal transplantation (P-CT), in eyes with no capsular support. METHODS: The records of 20 P-CT cases who underwent ICL implantation were retrospectively evaluated. The eyes were grouped according to the location of implantation; AC ICL and PC ICL. Pre- and post-surgical best-corrected visual acuity (BCVA), post-operative complications and graft rejection rates were compared between the two groups. Mean follow-up time was 28 (range, 12 and 76) months. RESULTS: ICLs were implanted during P-CT surgery in 14 (70%) eyes, and as a secondary procedure after P-CT in 6 (30%) eyes. ICLs were implanted in PC in 12 (60%) and in AC in 8 (40%) eyes. Mean preoperative BCVA was 0.064 (range, 0.001-0.02) in PC group and 0.02 (range, 0.001-0.1) in AC group (p=0.86). Mean postoperative BCVA was 0.17 (range, 0.0001-1.0) in PC group and 0.14 (range, 0.0001-0.4) in AC group (p=0.81). Glaucoma developed in 5 (41.6%) eyes with PC ICL. No eye with AC ICL developed glaucoma over time. DISCUSSION AND CONCLUSION: Both AC and PC ICL implantation provide favorable visual outcomes and complication rates in CT patients. However, PC implantation of ICL seems to increase glaucoma incidence.

Objective – To determine reasons authors choose to publish in open access (OA) education journals, which provides readers with unrestricted free online access to published articles, and investigate ways in which publishing practices in the discipline of education affects authors’ willingness to publish in these journals. Design – Web-based survey questionnaire. Setting – The survey was conducted over the Internet through email invitations. Subjects – A total of 309 authors who published in OA journals in education participated in this survey for a response rate of 27.9%. Methods – Researchers surveyed authors who published in selected education journals from 2007 to 2008. The journal titles where generated from the Directory of Open Access Journals (DOAJ). All chosen journals were peer-reviewed and published either original research or overviews of research results. In addition, all were in English and published in the United States. A total of 1,107 authors were invited to participate via email. The survey was delivered through commercial online survey tool SurveyMonkey and consisted of multiple choice and open-ended questions. It was open from early March to April 16, 2009. Main Results – The survey had a response rate of 27.9%. The majority of participants were tenured faculty (42.0%), tenure-track faculty (25.9%), and non-tenure track faculty (12.1%). The rest of participants (20%) consisted of adjunct instructors, graduate students, administrators, and individuals working in non-academic institutions such as government agencies. Most authors surveyed have published between 10 and 20 articles (20.6%), or over 20 articles (30.4%) in print and electronic journals (e-journals). The majority of authors also reported that one (23.3%) or between 2 to 5 (54%) of their articles was published in OA format. When choosing a journal for publications, authors surveyed ranked peer-review to be the most important determinant. Other important determinants included “good match” (ranked second most important) for authors’ manuscripts and reputation of the journal (third) and editorial board (fourth). Citation impact, such as the ISI impact factor (eighth), and copyright retention (tenth) were ranked as some of the least important factors. Researcher also noted a “surprisingly low” (p. 124) correlation between authors’ interest in copyright retention and practices of self-archiving. Thirty-seven percent of authors surveyed reported self-archiving at least one of their publications, but just over 35% of the same group considered copyright retention a determinant when choosing journals for publication. Overall, only 22% of the authors surveyed deemed e-journals to be “less desirable” than print journals. The majority of both tenured faculty (77.4%) and tenure-track faculty (72%) surveyed found e-journals “acceptable” or difference between print and electronic journal format “not an issue.” Only 16.8% of authors surveyed had published in journals that required author fees. Moreover, over 56% of authors indicated they would not publish in journals requiring such fees. Most authors reported they were either very aware (45.1%) or somewhat aware (38.9%) of the concept of OA publishing. However, their perceptions of OA publishing varied: • 47.7% believed OA journals have faster publication times, while 33.6% disagreed and 18.5% offered no opinion. • 57.3% of authors believed OA journals have larger readerships. However, when asked whether OA articles would be cited more frequently than others, only one third of authors agreed, while one third disagreed and one third offered no opinion. • Just under half of the authors (49.4%) thought OA journals are not less prestigious than subscription based journals, while 18.8% had no opinion. Lastly, it should be noted that only 7.1% of authors credited their institution’s library for making them aware of the OA publishing concept. Most credited their colleagues (42.1%), Google searches for publishing opportunities (40.4%), and professional societies (29.3%) for raising their awareness of OA. Moreover, based on voluntary general comments left at end of the survey, researchers observed that some authors viewed the terms open access and electronic “synonymously” and thought of OA publishing only as a “format change” (p.125). Conclusion – The study revealed some discipline-based differences in authors’ attitudes toward scholarly publishing and the concept of OA. The majority of authors publishing in education viewed author fees, a common OA publishing practice in life and medical sciences, as undesirable. On the other hand, citation impact, a major determinant for life and medical sciences publishing, was only a minor factor for authors in education. These findings provide useful insights for future research on discipline-based publication differences. The findings also indicated peer review is the primary determinant for authors publishing in education. Moreover, while the majority of authors surveyed considered both print and e-journal format to be equally acceptable, almost one third viewed OA journals as less prestigious than subscription-based publications. Some authors also seemed to confuse the concept between OA and electronic publishing. These findings could generate fresh discussion points between academic librarians and faculty members regarding OA publishing.
