As the role of information technology （IT） in business innovation becomes increasingly important, an increasing number of organizations have started to consider how to promote IT-enabled business innovation. Although extant studies have identified organization, environment, and innovation＇s characteristics as substantial determinants of IT innovation, they do not emphasize the accompanying innovation in processes, products or services, which distinguish IT-enabled business innovation from general IT innovation. Therefore, the reason why few companies succeed in realizing IT-enabled business innovation remains obscure. Anchored on the institutional entrepreneurship theory, this paper examines determinants of the success of IT-enabled business innovation in a fast-growing company using the case study approach. Our findings indicate that IT-business coordination competency, degree of institutionalization, participation of business managers, top management team＇s （TMT） attitude towards the innovation, and the innovation＇s relative strength, have significant impacts on the success of IT-enabled business innovation. Our findings also contribute to IT innovation research by identifying special determinants of IT-enabled business innovation and redirecting research ranging from innovation in IT itself to IT-enabled innovation in business processes, products or services.

Fluid flow can significantly change the evolution of microstructural morphology. However, relatively little is known how the fluid flow, concentration and microstructure affect each other quantitatively, which is essential to optimize processing parameters. A quantitative simulation study of Al-Cu solidified equiaxed dendrite evolution under forced flow based on phase field-lattice Boltzmann method(PF-LBM) is carried out. Results obtained are validated by Gibbs-Thomson relation at the dendrite tip. Compared with the equiaxed dendrite evolution without flow, the upstream dendrite arm is enhanced while the downstream arm is inhibited. Besides, as the inlet flow rate increases, the secondary arms attached onto the upstream primary arm and the upstream side of the primary arm normal to the inflow velocity has been well developed. Results show that sidewise instabilities of the primary dendrite arm and onset of secondary arm is caused by the local concentration perturbation and will be enhanced or inhabited by the flow. It is believed that the coupled PF-LBM method is able to handle dendrite evolution under forced flow quantitatively, which helps in investigating the solidified dendrite morphology evolution.

Gene expression studies are important for revealing gene functions putatively involved in biological processes. We were interested in identifying differentially expressed genes during leaf development in rice. We combined the RNA arbitrarily primed-polymerase chain reaction （***） and dot blot hybridization methods to screen a rice leaf primordium cDNA library. Three developmental stages during vegetative growth were examined. The cDNA clones showing different hybridization patterns were further analyzed and verified. Here we demonstrate that the combination of RAP-PCR and dot blot hybridization could provide an efficient and relatively low-cost cDNA library screening approach to discover genes not previously known to be associated with leaf development in rice, We believe that the findings described here will help to elucidate the molecular mechanism（s） underlying the developmental processes of rice leaf
