Tracing the footprint of knowledge spillover: Evidence from U.S.-China Collaboration in Nanotechnology

The impacts of international collaboration on research performance have been extensively explored in the last two decades. Most research, however, focuses on quantity and citation-based indicators. Utilizing the turnover of keywords, this study develops an integrative approach tracking and visualizing the shift of the research stream and tests it within the context of U.S.-China collaboration in nanotechnology. Continue reading Tracing the footprint of knowledge spillover: Evidence from U.S.-China Collaboration in Nanotechnology

Assessing nanocellulose developments using science and technology indicators

This research aims to examine scientific and technological trends of developments in nanocellulose based on scientometric and patent indicators obtained from the Science Citation Index and Derwent Innovations Index in 2001-2010.

Characteristics and popular topics of latest research into the effects of air particulate matter on cardiovascular system by bibliometric analysis

In recent years, many epidemiological and toxicological studies have investigated the adverse effects of air particulate matter (PM) on the cardiovascular system. However, it is difficult for the researchers to have a timely and effective overall command of the latest characteristics and popular topics in such a wide field. Continue reading Characteristics and popular topics of latest research into the effects of air particulate matter on cardiovascular system by bibliometric analysis

Combined biological and health effects of electromagnetic fields and other agents in the published literature

Electromagnetic field (EMF) radiation exerts both stand-alone and combined effects on biological systems. The present study examines the scope of the combined effects; i.e., identify effects on biological systems from combined exposure to electromagnetic fields/radiation and at least one other agent. Only articles in which the presence of EMF had some effect (beneficial or adverse) on the biological system were selected. Continue reading Combined biological and health effects of electromagnetic fields and other agents in the published literature

Technological Forecasting on Phytotherapics Development in Brazil

The prospective analysis is presented as an important tool to identify the most relevant opportunities and needs in research and development from planned interventions in innovation systems.   This study chose Phyllanthus niruri, known as “stone break” to
describe the knowledge about the specie, by using biotechnological forecasting through the software Vantage Point. It can be seen a considerable increase in studies on Phyllanthus niruri in recent years and that there are patents about this plant since twenty-five years ago. India was the country that most carried out research on the specie, showing interest, mainly in studies of hepatoprotection, antioxidant and anti-cancer activities. Brazil is in the second place, with special interest for anti-tumor studies. Given the identification of the Brazilian groups that exploit the species it is possible to mediate partnerships and cooperation aiming to help on the implementing of the Program of Herbal medicines (phytotherapics) in Brazil.

Enabling Policy Planning and Innovation Management through Patent Information and Co-Authorship Network Analyses: A Study of Tuberculosis in Brazil

New tools and approaches are necessary to facilitate public policy planning and foster the management of innovation in countries’ public health systems. To this end, an understanding of the integrated way in which the various actors who produce scientific knowledge and inventions in technological areas of interest operate, where they are located and how they relate to one another is of great relevance. Tuberculosis has been chosen as a model for the present study as it is a current challenge for Brazilian research and innovation. Continue reading Enabling Policy Planning and Innovation Management through Patent Information and Co-Authorship Network Analyses: A Study of Tuberculosis in Brazil

Effects of International Collaboration and Knowledge Moderation on China’s Nanotechnology Research Impacts

Recent studies have consistently reported that China is becoming a leading nation in scientific output, notably in the emerging field of nanotechnology. Given the existence of Chinese diaspora and reverse migration, the driver of such growth is presumed to be international collaboration. However, little evidence shows collaboration to be the principal determinant. The purpose of this article is to examine the impact of international collaboration on the research visibility of China nanotechnology. Continue reading Effects of International Collaboration and Knowledge Moderation on China’s Nanotechnology Research Impacts

Composing technology roadmapping according to bibliometrics: hybrid model and empirical study

Technology roadmapping is considered a powerful instrument for technology assessment and forecasting, and the composing model for technology roadmapping is also a hot topic in the field of technology visualization. This paper tries to introduce a bibliometric method involving with terms frequency analysis and association analysis to construct the objects and their relationships in the technology roadmapping, and blend with expert knowledge to locate each object in the appropriate layer and time interval. Continue reading Composing technology roadmapping according to bibliometrics: hybrid model and empirical study
