The perspective of philosophical thinking on lifting enterprise soft power requires us to enhance both hard power and soft power in the enterprise and to grasp more the fundamental contradiction-promoting soft power of corporation-at the same time. Focusing on the environment-relationship economy, emotional economy, cultural economy and moral economy-faced by enterprise, corporation should take relationship building, feeling cultivation, cultm'e construction and integrity establishment as an origin of force to improve the image, the group cohesion force, the social credibility and the cultural strength of the company. 展开更多

The accuracy of hard core attractive Yukawa (HCAY) potential and adhesivehard sphere (AH) potential in representing the structure factor of short range square well potentialand Asakura and Oosawa (AO) depletion potential is examined by comparing theoretical predictionswith the existing simulation data and the present numerical results from the non-linear optimizedrandom phase approximation closure for Ornstein—Zernike equation. For the case of square-well (SW)potential, it is shown that the structure factor of HCAY potential based on a recently proposedsemi-analytical expression for the radial distribution function can describe the structure factor ofSW potential with reduced well width λ ≤ 2 only if the reduced contact potential βε_(sw) ≤0.25, while the analytical expression for the structure factor of AH potential under Percus-Yevick(PY) approximation completely fails for the case of λ 】 1.2. For the case of AO depletionpotential, the domain of validity of both HCAY potential and AH potential is complementary. With theabove analysis and considering the solid-liquid transition of the AH potential with an adhesiveparameter τ below 1.31 cannot be predicted by modified weighted density approximation, the roleplayed by the HCAY potential about the mapping manipulation should not be ignored. 展开更多
