Purpose: First, to review the state-of-the-art in patent citation analysis, particularly characteristics of patent citations to scientific literature (scientific non-patent references, SNPRs). Second, to present a novel mapping approach to identify technology-relevant research based on the papers cited by and referring to the SNPRs. Design/methodology/approach: In the review part we discuss the context of SNPRs such as the time lags between scientific achievements and inventions. Also patent-to-patent citation is addressed particularly because this type of patent citation analysis is a major element in the assessment of the economic value of patents. We also review the research on the role of universities and researchers in technological development, with important issues such as universities as sources of technological knowledge and inventor-author relations. We conclude the review part of this paper with an overview of recent research on mapping and network analysis of the science and technology interface and of technological progress in interaction with science. In the second part we apply new techniques for the direct visualization of the cited and citing relations of SNPRs, the mapping of the landscape around SNPRs by bibliographic coupling and co-citation analysis, and the mapping of the conceptual environment of SNPRs by keyword co-occurrence analysis. Findings: We discuss several properties of SNPRs. Only a small minority of publications covered by the Web of Science or Scopus are cited by patents, about 3%-4%. However, for publications based on university-industry collaboration the number of SNPRs is considerably higher, around 15%. The proposed mapping methodology based on a "second order SNPR approach" enables a better assessment of the technological relevance of research. Research limitations: The main limitation is that a more advanced merging of patent and publication data, in particular unification of author and inventor names, in still a necessity. Practical implications: The proposed mapping methodology enables the creation of a database of technology-relevant papers (TRPs). In a bibliometric assessment the publications of research groups, research programs or institutes can be matched with the TRPs and thus the extent to which the work of groups, programs or institutes are relevant for technological development can be measured. Originality/value: The review part examines a wide range of findings in the research of patent citation analysis. The mapping approach to identify a broad range of technologyrelevant papers is novel and offers new opportunities in research evaluation practices. 展开更多

The objectives of this article are as follows: 1) to propose a university research ethics system framework, 2) to provide a brief anatomy of the Meru University of Science and Technology (MUST) Institutional Research Ethics Review Committee (MIRERC), 3) to perform a SWOT (Strengths, Weaknesses, Opportunities, and Threats) analysis of MIRERC, and 4) to make recommendations for improving its performance. The 13-member multi-disciplinary MIRERC was established in April 2017 to provide effective ethical oversight of research undertaken by the University’s scholarly community. Strengths of the MUST research ethics review system include a functional MIRERC, a pertinent national law and ethical guidelines, an Innovation and Enterprise Centre that could house a dedicated MIRERC Secretariat, and a supportive University Management Board. The weaknesses include lack of graduate schools to assure scientific rigor of proposals before submission to the MIRERC, lack of research ethics training in most school’s curricula, absence of a dedicated MIRERC Secretariat, undergraduate research proposals being not ethically reviewed, dearth of faculty trained in research ethics, and lack of an operating budget for MIRERC work. The opportunities include existence of about 22 accredited Institutional Research Ethics Review Committees (IRERC) in Kenya, existence of international standards and operational guidance for ethics review, availability of guidelines and codes of best ethical practices in research, existence of a free automated platform called Research for Health Innovation Organizer (RHInnO) Ethics for managing the ethics review process, and availability of external resources for strengthening IRERCs. In order to improve the performance and sustainability of the MUST research ethics system, there is need to include research ethics training in all undergraduate and post-graduate curricula, create a dynamic database of potential research ethics reviewers, allocate a percentage of the annual MUST research budget for MIRERC operations, charge a graduated fee for proposal ethics review, require all students’ and faculties’ internal and external research proposals be cleared by the MIRERC, and use the RHInnO Ethics platform to manage the ethics review process. 展开更多

Chengdu University of Technology (CDUT), located on the eastern edge of the Qinghai—Tibet Plateau, a higher education and research institution with a focus on geosciences, has paid special attention to scientific research on Q—T Plateau. In the earlier 1950s Professor Zhang Zhuoyuan, the former president of CDUT and Professor Ren Tianpei joined the geological survey in Tibet as members of the Tibetan geological working group organized by the Central Government of China. Since the 1980s, research on the Q—T Plateau has reached a golden age, and recognized this, CDUT established the Resources and Environment Research Center of Qinghai—Tibet Plateau in order to lead and coordinate the research around the Plateau continuously and smoothly. There are often more than 50 geologists involved in research during any given year. Scientists from CDUT are now conducting many kinds of research programs covering the whole area of the Plateau, from the Himalayas in the south to the Tianshan Mountains in the north, from the Longmen Mountains and the West Yunnan Plateau in the east to Ali area in the west. Scientists from CDUT have completed cooperative research programs with foreign scientists from the U. S., France, U.K., Japan, Austria, Canada, Germany and Australia. Research subjects include National Key Basic Research, State Scientific Key Projects, National Natural Scientific Foundation Projects, National Outstanding Young Scientists Foundation Projects, as well as Basic Geological Survey, Mineral Resources Evaluation, Analysis of Potential Oil and Gas Resources, Geohazard Protection.. More than 40 projects and 6 geological maps in different scales (1∶1000000, 1∶200000, 1∶50000) have been completed.. Research funding has increased to billions of yuan. Thousands relevant research papers and works have been published. More than 20 projects have won scientific achievement awards at national, ministerial and provincial levels. Meanwhile, a research group of young and middle\|aged scientists led by Prof. Wang Chengshan has formed and is determined to devote itself to the Q—T geological research. Many of them have broken established rules and have become professors or gained prizes. To strengthen Q—T research, the Ministry of Land and Resources specially established the Laboratory of Continental Dynamics of the Qianghai—Tibet Plateau at CDUT in 1999. Academicians, Li Tingdong and Liu Baojun, are the Honorary Directors of the Lab and the Academic Committee of the Lab respectively.
