They can be applied in approximating continuous functions with arbitrary growth order, defined on a finite interval or the whole real axis. The properties of approximation are studied and their asymptotic formulae are presented. These results show that their degrees of approximation are the best among existing operator sequences of Landau type, for example, their degrees of approximation for C 2[0, 1] are O(1/n 2) but corresponding degree of ordinary Landau operators are only O(1/n).展开更多

The city as an organic compound of space represents the organic integration in space of the elements of civilization, while its meaning provides the ethical ties that link these elements to form an organic whole. A city without a locus of meaning will be buffeted by risks and confrontations. The realization of sustainable urban prosperity requires the integration of the city as an ordered community of meaning at the same time as its physical forms take shape. An important practical path to achieving this aim is restructuring city space in a rational ＂spatial-ethical ecology＂ based on integrity and interaction of physical, social and psychological urban space, by means of collective action knitted together by meaning and carried out by communities and organizations.展开更多

This article argues that the early phase of development this Marxist concept implicates a deeper notion of injustice, which contains logic of linearity that can be further dissected into a trichotomous part worthy of our discussion, namely, temporal ordering, harsh treatment, and inhumane consequences. This ＂linearity＂ as assumed in this concept, nevertheless, was not unchallenged in history. As a matter of fact, in Mao＇s era, China deliberately sought an alternative path to the capitalist mode by attending to social welfare, physical well-being and rights protection for workers. This part of history is well worth re-investigation and re-interpretation.展开更多

文摘Rapidly urbanizing China is at a critical period in the construction of urban meaning and order. The city as an organic compound of space represents the organic integration in space of the elements of civilization, while its meaning provides the ethical ties that link these elements to form an organic whole. A city without a locus of meaning will be buffeted by risks and confrontations. The realization of sustainable urban prosperity requires the integration of the city as an ordered community of meaning at the same time as its physical forms take shape. An important practical path to achieving this aim is restructuring city space in a rational ＂spatial-ethical ecology＂ based on integrity and interaction of physical, social and psychological urban space, by means of collective action knitted together by meaning and carried out by communities and organizations.
