A bibliometric analysis of the research dealing with the impact of additive manufacturing on industry, business and society.

Purpose The ecosystem perspective on innovation and business has emerged as the secret sauce of innovative organizations. While its theoretical foundations are premised on innovation system literature, the broad adoption of the ecosystem concept has resulted in conceptual ambiguity. The purpose of this paper is to tackle the ambiguous use of innovation ecosystem terminology and structure a conceptual frame for the field, identifying definitions of an innovation ecosystem and how the concept has been established in previous literature. Design/methodology/approach This paper examines the ambiguous use of terminology by reviewing the literature with bibliometric coupling and co-citation analysis by which thematic differences in ecosystem literature were identified. The study gathered the scientific publications from Thomson Reuters Web of Sciences Core Collection (n=4,681) from 1990 to 2015. Findings Six major bibliometrically coupled clusters were identified, of which the three largest clusters are innovation system studies, regional innovation studies and technological innovation studies. In addition, further analysis shows an emerging cluster that is focused on ecosystems, having its roots in eight seminal papers. This ecosystem research cluster includes seven sub-clusters, such as innovation ecosystem studies, business ecosystem studies and studies focusing on ecosystem development. Research limitations/implications The authors’ approach highlights how a lot of recent ecosystem studies actually belong to previous, well-developed research streams. However, there is also a separate, emergent research stream that includes the innovation and ecosystem studies. As a research implication, the paper concludes by suggesting the research agenda for further studies. Originality/value Even though literature on innovation systems and ecosystems is extensive literature, no studies have captured the emergence of the ecosystems approach and its relation with the systems of innovation literature.

Service innovation through social robot engagement to improve dementia care quality

In the paper, we apply small world complex network theory to analyze scientific research in the field of service innovation, and discover its research focuses. Our study considers the key words and subject categories of the publications as actors to map keyword co-occurrence network and subject category co-occurrence network, and compare them with their corresponding random binary networks to judge whether these complex networks have the characteristics of small world network, in order to find the hot issues in the field by the small world network analysis. We discuss the knowledge structure in the field through analyzing 437 papers that were searched from Web of Science database over the period 1992---2011. We find that case study, service industry, service quality, market orientation, new product development, and knowledge management were the most popular keywords of the field, and also show the dynamic development of the research focuses in recent 10 years. The researchers who made most contribution in a certain field are also found out. It is concluded that there were more researchers who did investigation about service innovation in the category of Business and Economics, Engineering, Public Administration, Operations Research and Management Science, and Computer Science than those in other categories. The study suggests a quantitative method to analyze trends of scientific research in a certain field, and presents some directions of research mainstream to the researchers who may be interested in the service innovation.

A bibliometric study of service innovation research: based on complex network analysis

This study introduces nation diffusion breadth and nation diffusion intensity by adapting the notions of field diffusion breadth and field diffusion intensity as defined by Liu and Rousseau, and a variation on the total cited influence indicator introduced by Hu et al. Knowledge diffusion across countries in the field of management is then analyzed as a case study. Main countries in the field of management studies are considered as centers in their own ego-centered citation networks. The three indicators mentioned above are then calculated for these ego-centered citation networks. They measure the scientific impact each of these countries has on other nations. A general picture of the knowledge diffusion process is given by the three indicators at the country level over four periods 1992---1996, 1997---2001, 2002---2006, and 2007---2011. The validity of the proposed indicators is verified by the calculated results.

Objective: Using network pharmacology and molecular docking method to predict the main active components and targets of Jiufen Powder in the treatment of rheumatoid arthritis, and to analyze the mechanism of its multi-component, multitarget and multi-pathway. Methods The active components of four traditional Chinese medicines (semen strychni, ephedra, frankincense, myrrh) were collected and screened in the TCMSP, PubChem and Swiss Target Prediction database, and predict their targets; Screening of disease targets associated with rheumatoid arthritis treatment through OMIM and GeneCards databases; Intersecting with Jiufen Powder active component targets to screen out common targets as research targets, A potential protein interaction network was constructed by inputting their common targets into String online analysis platform; Use Cytoscape 3.7.2 software to construct a drug-active component-target visualization network, and use the Metascape platform to perform GO and KEGG enrichment analysis on its core targets to predict its mechanism of action; molecular docking of key targets through molecular docking technology verification. Result The key targets were verified by molesults A total of 40 active components were obtained by screening OB≥30%, DL≥0.18, and corresponding 186 potential action targets; Using "Rheumatoid arthritis" as the key word search for 4465 disease-related targets, and mapped them to potential drug targets,get 124 common targets, among which 9 targets may be useful for the core target of Jiufen Powder treatment of rheumatoid arthritis; A total of 231 nodes and 962 edges were read in the "drug-active component-target" network diagram; There are 22 different signaling pathways in the GO and KEGG enrichment analysis, including the PI3K-Akt signaling pathway , Proteoglycans in cancer, MAPK signaling pathway, chemokine signaling pathway, IL-17 signaling pathway, etc; Molecular docking shows that the compounds in Jiufen Powder have high binding energy with key proteins that cause rheumatoid arthritis. Conclusion Through multi-target and multi-pathway, the potential mechanism of Jiufen Powder in treating rheumatoid arthritis was preliminarily explored, which provided scientific basis for the clinical application and in-depth study of Jiufen Powder.
