知识资本构成分析及其技术评价

首先从人力资本、结构资本、技术资本和市场资本四方面构建知识资本，并较详细地分析了每部分的主要构成。然后，系统地介绍了如何对其评价，提出利用特尔斐方法先建立指标体系，然后利用语义差别隶属度赋值方法把定性指标定量化，采用模糊隶属赋值法将定量化指标无量纲处理，同时引入AHP法确定评价指标权重。最后采用分级处理思想对知识资本进行综合评价，并得出知识资本的综合评价模型。这种分级处理的思想，既有利于解决知识资本评价中遇到的错综复杂的关联性，而且通过这种分类分级评价，易于通过软件的开发来辅助评价。

Do knowledge conditions make a difference?: Investment, finance and ownership in German industries

This paper examines the impact of industry knowledge conditions, the mode of corporate control and firm size on tangible investments and its financing. Based on a large panel data set of German firms we investigate whether financing constraints exist for tangible investment and whether there is systematic variation across firms engaged in activities reflecting different knowledge conditions. In particular, we compare the extent of financing constraints for firm in knowledge intensive (hi-K) industries with those in less knowledge-based (lo-K) industries. This distinction is important because knowledge-based economic activity tends to be subject to high degrees of uncertainty, asymmetric information and spillovers of newly created knowledge, making access to external sources of finance difficult. Our surprising empirical finding is that firms in hi-K industries are less finance constrained than are their counterparts in lo-K industries. However, the mode of corporate control and firm size play an important role. After controlling for firm size and manager versus owner control, we observe that the small manager-controlled firms in both hi-K and lo-K industries are most finance constrained. By contrast, no financing constraints seem to exist for the smaller owner-controlled firms in hi-K industries. This latter result contrasts sharply with results of Anglo-Saxon studies.

Sin1-mediated mTOR signaling in cell growth,metabolism and immune response

The mammalian target of rapamycin (mTOR) is an evolutionarily conserved Ser/Thr protein kinase with essential cellular function via processing various extracellular and intracellular inputs. Two distinct multi-protein mTOR complexes (mTORC), mTORC1 and mTORC2, have been identified and well characterized in eukaryotic cells from yeast to human. Sin1, which stands for Sty1/Spc1-interacting protein1, also known as mitogen-activated protein kinase (MAPK) associated protein (MAPKAP)1, is an evolutionarily conserved adaptor protein. Mammalian Sin1 interacts with many cellular proteins, but it has been widely studied as an essential component of mTORC2, and it is crucial not only for the assembly of mTORC2 but also for the regulation of its substrate specificity. In this review, we summarize our current knowledge of the structure and functions of Sin1, focusing specifically on its protein interaction network and its roles in the mTOR pathway that could account for various cellular functions of mTOR in growth, metabolism, immunity and cancer.
