Gilman not only creates a political vacuum, where the whole patriarchal civilization, including patriarchal system, superstructure, ideology, influence, and consciousness have ceased to exist, but also men are done away with all together. Most reviews claim that Herland criticizes the patriarchal tradition and manifests concern for humanity and some even regard Herland as the first truly feminist work in the American tradition. But this supposedly utopian world is actually static, without possibilities of growth and even inhuman, gothic, and nightmarish. And this is because Gilman constructs the women＇s utopia out of the conviction in women＇s superiority over men. Herland is a little paradise that is designed too perfect. Women＇s utopias still need to promote social change in the real world展开更多

文摘For a graded algebra,the minimal projective resolution often reveals amounts of information.All generated degrees of modules in the minimal resolution of the trivial module form a sequence,which can be called the degree distribution of the algebra.We try to find lower and upper bounds of the degree distribution,introduce the notion of(s,t)-(homogeneous) determined algebras and construct such algebras with the aid of algebras with pure resolutions.In some cases,the Ext-algebra of an(s,t)-(homogeneous) determined algebra is finitely generated.
