战略创业是创业和战略管理相结合的产物,创业活动和战略行为的互补有利于企业实现财富最大化。战略研究与创业研究的结合,有利于更好地分析企业是如何识别开发创业机会,建立和保持竞争优势能力,以及如何动态运作战略创业以创造财富。目前,战略创业已成为国际学术界的研究热点,美国战略管理学会为此特别设立了《战略管理》杂志的姐妹刊物:《战略创业》杂志,但是国内对于这一国际学界的发展方向还没有给予应有的重视。

Secure group communications are restrained by the number of the group size, number of changes and their distribution, all existing works do not meet the commands of applications with large group size and high dynamic members. In this paper, minimum exact cover problem for group key distribution （GMECP） is presented, and a heuristic solution is testified. Then an algorithm of batch rekeying with renewing cost tending to zero is illustrated, which can process any large number of change requests with best security guaranteed. Efficiency analysis and simulation test show that the achievement can improve the efficiency of any tree-based group key management.

Based on elaboration likelihood model, this study extends the existing research by investigating how different levels of relatedness of feeling-based ad claims influence degrees of attitude persistence. Results revealed significant main effects of cue relatedness on attitude persistence regardless of the involvement levels. However, the degrees of attitude persistence reduced greater under low rather than high-involvement conditions. This study also found that ad claims, which are verbal-based peripheral cues, influenced attitude persistence differently from those non-verbal cues. These findings have both theoretical and managerial implications.

Based on the measuring data and Digital Elevation Data (DEM) in a typical watershed--Hemingguan Watershed, Nanbu County, Sichuan Province of china, a GIS-based distributed soil erosion model was developed particularly for the purple soil type. It takes 20 m × 20 m grid as calculating unit and operates at 10-minute time interval. The required input data to the model include DEM, soil, land use, and time-series of precipitation and evaporation loss. The model enables one to estimate runoff, erosion and sediment yield for each grid cell and route the flow along its flow path to the watershed outlet. Furthermore, the model is capable of calculating the total runoff; erosion and sediment yield for the entire watershed by recursion algorithm. The validation of the model demonstrated that it could quantitatively simulate the spatial distribution of hydrological variables in a watershed, such as runoff, vegetation entrapment, soil erosion, the degree of soil and water loss. Moreover, it can evaluate the effect of land use change on the runoff generation and soil erosion with an accuracy of 80% and 75% respectively. The application of this model to a neighboring watershed with similar conditions indicates that this distributed model could be extended to other similar regions in china.

Perceived risk is an important concept in consumer behavior in online shopping. It impedes the adopting online shopping. A structure model with seven factors of consumer's perceived risk in online shopping is developed in this paper. The results have the descriptive power about Chinese consumers' perceived risk in Internet shopping and provide framework for managerial use in china's e-commerce market environment.
