基于EPO、 JPO、KIPO、SIPO、USPTO、WIPO六个主要专利审查机构的专利数据,对比分析了中国科学院与五家国际科研机构的全球专利布局与技术创新能力,从中发现,中国科学院的技术水平相较于其他国际科研机构并不存在显著劣势,但其专利布局过于集中在中国国内,对于产业界的技术影响力也极为有限。作为在基础研究领域取得了巨大国际影响力的中国科学院,在未来的科研工作中需要扭转“基础研究国际化,技术研发内卷化”的局面。而这一方面要求中国科学院在专利布局方面要拥有全球科技战略大局观,另一方面要更多地参与产业技术研发,将自身的科研工作与产业技术需求进一步接轨。 相似文献

Geographical Information Systems or GIS has become one of the more prominent research and training tools in South African university departments in the 1990s. GIS developed in the 1970s in North America in response to the expanding capacity of computer systems and the need to integrate spatial and attribute data (Maguire et al, 1991). It was only in the mid‐1980s that the first systems were set up in South Africa, primarily at research institutions such as the Department of Water Affairs and the Institute for Natural Resources in Pietermaritzburg. Since then the use of the technology has grown exponentially and most of the country's major municipalities (Szecsei, 1990; Van Rensburg, 1992), government departments, town and regional planners (Zietsman, 1992; Venter, 1993), engineering concerns (Poolman, 1990) and universities have become regular users. At universities GIS is used more as a research tool than as a defined analytical procedure. This article reviews the development of GIS and its use in South African universities. It also discusses the advantages and impediments to the use of the technology and its development. 相似文献

ABSTRACT Assessing the social impact of tourism-related activities is of paramount importance to promoting sustainable development. The present study aimed to assess the social impact of a project in Cabo Delgado (MZ), designed to increase local community residents’ employability in the emerging tourism sector through the delivery of vocational training programmes, utilising a multi-phase and mixed-method design. The study comprised three different phases (before, during, and after the intervention) and took into account the perspective of a variety of stakeholders. Programmes were perceived to be effective by local operators in the tourism sector and trainees, as they enhanced their living conditions and increased their employability. International operators and tourists, however, had not yet perceived their effectiveness. This study offers a methodological framework for social impact assessment by performing a programme evaluation as an integral part of the intervention itself. This methodology can be extended to other non-tourism related contexts. 相似文献
