This paper analyzes on the developing chance and negative influence brought about by the educational evaluation to the library,and advances some new tactics on how the university library to correctly recognize and treat the educational evaluation.
This paper mainly analyzes the positive and negative influences of network on the university students' ideological education,thus correctly guiding the students,developing its positive effects and raising the level of university students' ideological education.
They had higher score than those of normal controls in Negative Affect (14.4±5.2) and Social Inhibition (13.1±7.3) of DS (t=11.7,t=5.0,P<0.01), and there was significantly positive correlation between anxiety and Negative Affect (r=0.69,P<0.01).
In the present paper we study the remaing nontrivial case, that of a negative central charge-N.
CAT(-1) spaces are generalizations of manifolds with negative curvature.
We consider contractible affine surfaces of negative Kodaira dimension with only quotient singularities.
We prove that the smooth locus of such a surface has negative Kodaira dimension.
We characterize, for finite measure spaces, those orthonormal bases with the following positivity property: if f is a non-negative function, then the partial sums in the expansion of f are non-negative.
