At the same time, analyses for time correlation variance and subject correlation variance are used to present the formation of overlapping structures in scientific networks. As a test, a co-citation network of highly cited papers on Molecular Biology & Genetics from Essential Science Indicator(ESI) is taken as an example for an empirical analysis.Findings: Our research showed that the Q-value variance is effective for achieving the desired overlapping structures. Meanwhile, the time correlation variance and subject correlation variance are equally useful for uncovering the evolution progress of scientific research, and the properties of overlapping structures in the research of co-citation network as well.Research limitations: In this paper, the theoretical analysis and verification of time and subject correlation variances are still at its initial stage. Further studies in this regard need to take actual evolution of research areas into consideration.Practical implications: Evolution properties of overlapping structures pave the way for overlapping and evolution analysis of disciplines or areas, this study is of practical value for the planning of scientific and technical innovation.Originality/value: This paper proposes an analytical method of time correlation variance and subject correlation variance based on the evolution properties of overlapping structures, which would provide the foundation for the evolution analysis of disciplines and interdisciplinary research.展开更多

Design/methodology/approach: Records retrieved from Web of Science were submitted to author co-citation analysis(ACA) following a longitudinal perspective as of the following time slices: 1986–1996, 1997–2006, and 2007–2015. The top 10% of most cited first authors by sub-periods were mapped in bibliometric networks in order to interpret the communities formed and their relationships.Findings: KM is a homogeneous field as indicated by networks results. Nine classical authors are identified since they are highly co-cited in each sub-period, highlighting Ikujiro Nonaka as the most influential authors in the field. The most significant communities in KM are devoted to strategic management, KM foundations, organisational learning and behaviour, and organisational theories. Major trends in the evolution of the intellectual structure of KM evidence a technological influence in 1986–1996, a strategic influence in 1997–2006, and finally a sociological influence in 2007–2015.Research limitations: Describing a field from a single database can offer biases in terms of output coverage. Likewise, the conference proceedings and books were not used and the analysis was only based on first authors. However, the results obtained can be very useful to understand the evolution of KM research.Practical implications: These results might be useful for managers and academicians to understand the evolution of KM field and to(re)define research activities and organisational projects.Originality/value: The novelty of this paper lies in considering ACA as a bibliometric technique to study KM research. In addition, our investigation has a wider time coverage than earlier articles.展开更多

However, quantitative and systematic reviews on those findings are rarely conducted by researchers. Therefore, a visualized presentation regarding the advancement of nZEB research was made in this study by applying the scientometric method of co-citation analysis to 704 publications retrieved from the Web of Science database from 2006 to 2018. Here, the key conclusions drawn after the research are as follows:(1) Italy, the USA and Spain are the top three nations by the number of nZEB publications;(2) Energy and Buildings, Applied Energy and Energy are the journals with the highest number of published nZEB articles;(3) Politecnico di Milano, Aalto University and Politecnico di Torino are the most influential core organizations in the field of nZ EB;(4) Professor Kurnitski J, Professor Corgnati SP and Professor D’Agostino D are the leading nZEB experts;(5) "cost optimal", "life cycle assessment", "technical system", "design" and "indoor environment quality" are the major research directions in the field of nZEB;(6) A multi-stage optimization method for cost-optimal and nearly zero-energy building solutions in line with the EPBD 2010, co-authored by Hamdy M, is the most cited nZEB reference;(7) "residential building", "building energy saving technology", "simulation method" and "thermal comfort", etc. are the hot topics in nZEB research at present and in the future. This research is designed to provide valuable information for scholars interested in the field of nZEB.展开更多
