Purpose The modern knowledge-based economy acknowledges the role of the third mission of universities related to the process of knowledge transfer as a driving force to face sustainability issues, in addition to the two traditional missions focusing on research and teaching. The purpose of this paper is to investigate the relationships between internal environment, external environment, knowledge exploitation, knowledge exploration and university performance. Design/methodology/approach This study applies confirmatory factor analysis and structural equation modelling to test the conceptual model in the Chinese education system. Findings The findings confirm the higher impact of internal environment on both knowledge exploitation and knowledge exploration as compared to external environment. Knowledge exploitation is more strongly related to university performance than knowledge exploration. These results highlight the imperative role of internal university stakeholders in fostering knowledge management strategies. In addition, they encourage academicians, practitioners and policy makers to focus their attention on the impact of knowledge management models, tools and practices in universities to achieve the entrepreneurial development which, in turn, has a positive impact on individual graduates and innovation ecosystems. Originality/value The necessity to develop a more entrepreneurial university, as well as the lack of evidence of their development in emerging countries, highlights the need to investigate how specific factors and knowledge management processes are impacting the universities’ performance. In fact, although previous studies provide an explanation of the impact of internal and external factors on a university’s performance, contributions integrating these concepts with strategic knowledge management processes are still lacking.

PurposeThis paper seeks to examine the export competitiveness and concentration level of the 15 top sugar exporting countries over the last 18 years (2001–2018) with special reference to India.Design/methodology/approachFirst, the paper utilizes a review based approach and explains the structures of major sugar economies in context to protected and unprotected perspectives. Subsequently, empirical research was carried out to assess the competitiveness level of sugar using Revealed Comparative Advantage (RCA) approach and Hirschman Herfindahl Index.FindingsThe study found structural changes in cane or beet sugar, and molasses over the time period between 2006 and 2015. Further, the findings confirmed that despite the stringent regulations in European Union, the United States of America, Guatemala, Mexico, Thailand, China, and India, the comparative advantage is high up to seven to nine sugar categories. Besides, despite the indulgent regulations in the Colombia, Brazil, and Canada, the comparative advantage is only consistent up to two to three sugar categories.Research limitations/implicationsThis study provides an overview of competitiveness patterns of 15 sugar exporting countries and further compare their comparative and concentration levels. In this context, in future, it would be interesting to study the macro-economic and firm and industry-specific factors which may strengthen the study findings.Practical implicationsThis study suggests that the sugar export of few countries (i.e. Mexico and Canada) is restricted up to their trade pacts and free trade zones which is restricting the competitiveness level and performance. Accordingly, such countries need to enlarge their business boundaries to foster their export competitiveness level. Rational subsidies and governmental assistance in diversification schemes in terms of products' range and sustainable processes can make India a consistent exporter in more categories.Originality/valueAlthough, the previous studies attempted to examine the sugar industry with particular country context, this study enlarge the body of knowledge through simultaneously examining the sugar export scenario of fifteen sugar exporting countries and providing a broad comparative view of their competitiveness and concentration levels.

In recent years, knowledge management (KM) has consistently attained considerably growing research attention. Consequently, several literature reviews have been performed addressing different topic areas of KM. This paper seeks to present a comprehensive bibliometric and network analysis on KM to understand its development from the perspective of academic communities. Subsequently, it seeks to identify the structure of associations between prior and current themes, predict emerging trends and offer a longitudinal perspective on KM research. This study used web of science database and the initial sample was trimmed down by considering only the articles contributing to KM literature, and further 8,721 KM papers published in the last 30 years were systematically evaluated. The descriptive statistics and science mapping methods employing co-citation analysis were performed with VOSviewer software. In the descriptive analysis, we have analysed publication trends over time, geographical localization of the contributing institutions, journals, most prolific authors, top-performing institutions and most cited articles. Science mapping analysis is based on co-word analysis and co-citations analysis, namely articles’ co-citations and authors’ co-citations. The main findings of this paper will help researchers and academicians to develop knowledge in a specific sub-field by analysing the research outcomes of the papers included in the body of literature.

The first total synthesis of enisorine D, a natural product isolated from the marine sponge Iotrochota cf. iota, is described in 64% overall yield. The target molecule, which is an inhibitor of T3SS-dependent Yope secretion of Y. pseudotuberculosis, is achieved in seven linear steps from tyramine via simple and effective transformations that include bromination, acylation, alkylation, azidation, reduction and routine acid–amine coupling. A total of sixteen analogues are prepared by coupling with eight different cinnamic acids, two bromopyrrole carboxylic acids, five phenyl carboxylic acids and picolinic acid.

Currently in world wide computing (Cloud) has a great impact on life. Everyone can access the all services of cloud if he/she is on different location. Client user can access the cloud services as per their requirement. If one user on cloud, Integrity of data is an important aspect. Data integrity is the upkeep of and the confirmation of the exactness and consistency of, data over its whole life-cycle, and is a basic perspective to the outline, execution and use of any framework which stores, forms, or recovers data. In this research paper, a fitting technique that guarantees the integrity of data and in addition rightness of calculations done by the cloud service provider is introduced. Integrity is a method for protecting the consistency of the put away data in cloud server and guaranteeing the innovation of the data put away in the cloud server. It implies that the data can be altered just by approved people, along these lines expanding the certification, confirmation and dependability of the cloud service providers.

BACKGROUNDDoppler sonography has become a part of routine antenatal surveillance in Obstetrics during past decade. Colour Doppler can be used to distinguish between low and high risk pregnancies.
