我国出台行政法规鼓励非公有资本参与出版中下游产业,但是科技期刊的控制经营依旧是非公有资本的法律“禁区”。在实践层面,非公有资本早已悄然进入到科技期刊出版领域,造成了租售稀释版面、滥收版面费,期刊与中介勾连、逐级分销版面,申请境外刊号、规避禁入政策等乱象。非公有资本渗透科技期刊出版领域归因于科技期刊办刊资金普遍不足,科技期刊版面供需结构紧张,科技期刊市场化道路推波助澜。针对非公有资本渗透科技期刊办刊产生的诸多风险,本文从民法层面、行政法层面、刑法层面和国家安全法层面提出了综合规制的建议。 相似文献

在解构主义和阐释学的观照下,译者主体性成为当代翻译理论的重要命题.古诗作为一种文学表现形式,韵律美感强,句式整齐,对仗工整,风格特点明显,在翻译中尤其可以体现出译者的主体性。本文从“诗圣”杜甫的一篇著名五言律诗——《月夜》的6种译文文本入手,在意象再现与意境再造、人称视角的选取、韵律与形式的再创造等三个方面作分析比较,揭示了译者主体性在唐诗英译过程中的内涵和研究意义。 相似文献

We developed a new method for releasing viable cells from affinity-based microfluidic devices. The lumen of a microchannel with a U-shape and user-designed microstructures was coated with supported lipid bilayers functionalized by epithelial cell adhesion molecule antibodies to capture circulating epithelial cells of influx solution. After the capturing process, air foam was introduced into channels for releasing target cells and then carrying them to a small area of membrane. The results show that when the air foam is driven at linear velocity of 4.2 mm/s for more than 20 min or at linear velocity of 8.4 mm/s for more than 10 min, the cell releasing efficiency approaches 100%. This flow-induced shear stress is much less than the physiological level (15 dyn/cm2), which is necessary to maintain the intactness of released cells. Combining the design of microstructures of the microfluidic system, the cell recovery on the membrane exceeds 90%. Importantly, we demonstrate that the cells released by air foam are viable and could be cultured in vitro. This novel method for releasing cells could power the microfluidic platform for isolating and identifying circulating tumor cells. 相似文献

The capability of 3D printing technologies for direct production of complex 3D structures in a single step has recently attracted an ever increasing interest within the field of microfluidics. Recently, ultrafast lasers have also allowed developing new methods for production of internal microfluidic channels within the bulk of glass and polymer materials by direct internal 3D laser writing. This review critically summarizes the latest advances in the production of microfluidic 3D structures by using 3D printing technologies and direct internal 3D laser writing fabrication methods. Current applications of these rapid prototyped microfluidic platforms in biology will be also discussed. These include imaging of cells and living organisms, electrochemical detection of viruses and neurotransmitters, and studies in drug transport and induced-release of adenosine triphosphate from erythrocytes. 相似文献

A variety of the web-mining techniques are now being extensively utilized to extract useful knowledge about customer behaviors on the Internet. However, the naive interpretation of the web-mining results would lead to poor decision on customer behaviors, which is likely to cause waste of time and efforts on managing electronic commerce strategy. To overcome this pitfall, this study proposes using the cognitive map-based interpretation of the web-mining results. Conventional approach to obtaining the web-mining results is based on the association rule approach (ARA), while the cognitive map approach (CMA) is believed to provide more robust support in interpreting the web-mining results. Therefore, to compare the interpretation capability of the two approaches, the four constructs such as perceived usefulness, causality, information richness, users’ attitude and intention to use the approaches are adopted in the research model and tested against the questionnaire data. The test results obtained through applying the structural equation models reveal that CMA is comparable to ARA and the cognitive map has a great potential in helping enrich the interpretation of the web mining results and build more effective Internet business strategy. 相似文献
