This study presents a framework for mapping rainfall-induced landslide susceptibility in the Wencheng area of Zhejiang Province, China, using support vector machine (SVM). Seven conditioning factors of elevation, slope, aspect, distance to roads, lithology, land use, and normalized difference...

By empirical demonstration, this study extends the assessments of BRICS countries (Brazil, Russia, India, China and South Africa) in performing science and technology in previous studies by exploring their cumulative patterns of science and technology (proxied by publications and patents...

<title>Abstract</title> Despite their increasing importance worldwide, community foundations remain rare in much of East Asia. This comparative analysis of three community-based foundations currently operating in Japan, China and South Korea seeks to understand the role they play and factors that promote or...

Along with the rapid growth of nanoscience research and the wide application of nanotechnology into various industrial fields, the innovation patterns and co-evolutionary natures of multiple nano industrial sectors has drawn much attention from scholars. Based on a continuously updated...

This paper focuses on the role of interregional technology spillovers in the process of industrial growth in Chinese regions in the period 1990-2005. Inflows of FDI increased rapidly from 1990 till 1998, slowing down thereafter. Domestic R&D investment accelerated after 1998. Regional industrial...
