To explore diversified pension model for China has become the key to solve this problem. In 2013 the state council issued an document named Opinions to Speed Up the Derelopment of Pension Services, which clearly put forward that the government should promote the elderly housing reverse mortgage endowment insurance pilot ＂. ＂To implement housing endowment＂, practiced successfully in European and American countries, has proved a good way to solve the problem of lack of pension. This paper makes a analysis of the model, including the necessity,some practice and restricting factors promoting in our country, so as to explore countermeasures and Suggestions of the feasibility.展开更多

He spent many years in Europe. Fie had deep and subtle insights into the life of the upper class in America and Europe. He experienced the cultural differences between America and Europe profoundly, which was demonstrated in his literary works. Daisy Miller is one of the representative works of Henry James, reveals his ＂international theme＂, the American innocence in face of European sophistication, In D^dsy Miller, Winterbourne is an undeniable protagonist, embodies both narrative and symbolic meaning. Through his narration and his representative features of the sophistication of European culture, we can gradually realize that it is the inevitable collision between new world and old world that leads to the pathetic ending of Daisy Miller.展开更多

Ex...In the last three decades, the rise of a populist challenge to the liberal political mainstream exposed how shallow the supposed victory of global liberalism was, even in its heartlands in Europe and North America. Exclusive nationalism and nativism, identity politics, critiques of globaiisation and internationalism, and calls for democratic re-empowerment of the demos have converged politically on a new locus of inflated territorial, indeed ＇border＇ sovereignty, aligning the caU of ＇taking back control＇ on behalf of a radically re-defined community （＇we＇） with a defensive re-territorialisation of power along existing fault lines of nation-statism. In this paper, I argue that the very same call has become the new common political denominator for all populist platforms and parties across Europe. I argue that populists across the conventional left-fight divide have deployed a rigidly territo- rialised concept of popular sovereignty in order to bestow intellectual coherence and communicative power to the otherwise disparate strands of their anti-utopian cri- tiques of globalisation. In spite of significant ideological differences between so- called fight- and left-wing populism, in the short-term the two populist projects have sought to stage their performances of sovereigntism on, behind or inside the borders of the existing nation-states.展开更多
