Molecular imaging, as an emerging technique in current medical diagnostics, therapy and biology science, has received more and more attention in academia, industry, as well as medical practices. And the applications of nanotechnology in this field stimulate its development. This paper explores the development of the basic research and applied research on nano-enhanced molecular imaging, and does the in-depth analysis by adopting the bibliometrics method. The results show that the US is the leader in this field, who has the absolute advantages. Germany, UK and France and Japan are the followed ones. The rapidly developing Asian countries , China and South Korea might become the potential competitors. Research network analysis draws the conclusion that the other countries and regions share the same research interests with the US. The US not only take the lead in the researching number, but also directing the future orientation of this field. However, the US has not much international collaboration. The collaboration within the country and regions show that collaboration in this field is limited to the regional adjacency. Disciplinary analysis reveals that the major subjects which relate intimately to the nano-enhanced molecular imaging are chemistry, biomedical science and material science. 相似文献

As the Internet has changed communication, commerce, and the distribution of information, so too it is changing psychological research. Psychologists can observe new or rare phenomena online and can do research on traditional psychological topics more efficiently, enabling them to expand the scale and scope of their research. Yet these opportunities entail risk both to research quality and to human subjects. Internet research is inherently no more risky than traditional observational, survey, or experimental methods. Yet the risks and safeguards against them will differ from those characterizing traditional research and will themselves change over time. This article describes some benefits and challenges of conducting psychological research via the Internet and offers recommendations to both researchers and institutional review boards for dealing with them.

The five articles that make up the bulk of this special issue collectively illustrate new methods for examining the utility of sub-test and scale-level profile analysis. By necessity they are preliminary, but they illustrate methods that may indeed prove useful and may help resolve this divide between research and practice. This special issue grew out of a symposium conceived and organized by Cecil Reynolds at the American Psychological Association in 1998. The articles and one of the commentaries in this special issue are extensions of that symposium. (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

Based on the organization cooperation, from the perspective of variable correlation and variable proper ties, this paper describes the research result on relationship between trust and knowledge transfer, in which the elements correlation research is broken down relationship between trust and knowledge transfer, correlation of trust, knowledge transfer and performance relationship, and the interrelationships of trust, knowledge transfer and multiple factors. For trust perspective. There are two structural dimensions of trust: antecedents and media ting variables. Combining the literature at home and abroad in recent years, the existing research results are summed ul and the future research directions are nronosed. 相似文献
