Ricci flow on compact K\"ahler manifolds of positive bisectional curvature

We announce a new proof of the uniform estimate on the curvature of solutions to the Ricci flow on a compact K\"ahler manifold $M^n$ with positive bisectional curvature. In contrast to the recent work of X. Chen and G. Tian, our proof of the uniform estimate does not rely on the exsitence of K\"ahler-Einstein metrics on $M^n$, but instead on the first author's Harnack inequality for the K\"ahler-Ricc flow, and a very recent local injectivity radius estimate of Perelman for the Ricci flow.Comment: 4 page

A Research Review on Entrepreneurial and Intrapreneurial Characteristics

The enthusiasm for entrepreneurial management in the past two decades has leaded a definition for the boundary and legitimacy. Entrepreneurial research is no longer focused on the individual level of characteristic traits, but extends to multi-level analysis, e.g. prior experience, corporate culture, social relationships, and educational background. The paper intends to review researches on entrepreneurs and intrapreneurs for the purpose of identifying the similarities and differences between the two. We found that entrepreneurs tend to be higher risk taking, and uncertainty bearing, and intrapreneurs are better in communication and leading techniques. This paper tries to review, organize, and analyze the previous research contributions and hopes to provide managers with a practical reference for personnel filtering, training, and policy making as it gives employees an advanced mechanism for self-evaluation as a potential entrepreneur/intrapreneur
