Since its publication, it remains an indisputably classic text and arguably Conrad's finest work. And it has been regarded as a significant text in British literature because of its modernistic features, innovative narration and artistic style. Heart of Darkness deals with the highly disturbing effects of economic, social and political exploitation of European and African societies. It has inspired filmmakers and such authors as F. Scott Fitzgerald, Gabriel Garica Marquez, D. H. Lawrence and Virginia,Woolf. This article is aimed to analyse it from the perspective of primitiveness and civilization. Through the analysis, readers can sense Conrad's attitude towards the two aspects.展开更多

Yes, we have had revolutions against the disciplinary apparatus and legal devices of power (schools, hospitals, prisons) and we have had examples of revolutions against the economic foundations of social inequality, but there has never been a genuine revolution against pastoral power as a power relating to the conduct of individuals (but also entire social groups) and their disposition to “voluntary submission” to the will of external authorities. In my paper, I would like to reflect on this thesis, and taking it quite seriously, to look for examples of such revolutions. One of them is a women’s strike in Poland during the power of the conservative government of “Law and Justice”. Mainly referring to the texts of Silvia Federici and Paul Preciado, I will want to reflect on contemporary practices of reclaiming the body in contemporary capitalism. I will defend the thesis that regaining control over sexuality and reproduction means changing the material conditions of life and modern reproductive technologies.展开更多

In particular, we prove that the scaled Boussinesq equations strongly converge to the viscous primitive equations with density stratification as the aspect ratio goes to zero, and the rate of convergence is of the same order as the aspect ratio. Moreover, in order to obtain this convergence result, we also establish the global well-posedness of strong solutions to the viscous primitive equations with density stratification.展开更多

The goal is to reduce time consumption in data format conversion and the requirement of network bandwidth so as to improve the cooperative ability and the synchronization efficiency. Firstly, real-time collaborative design is reviewed and three kinds of real-time collaborative design models are discussed. Secondly, the concept of operation semantics is defined and the framework of an operation semantics model is presented. The operation semantics carries the original design data and actual operation process to express design intent and operation activity in conventional CAD systems. Finally, according to the operation semantics model, a CAD operation primitive is defined which can be retrieved from and mapped to the local CAD system operation commands; a distributed CAD collaborative architecture based on the model is presented, and an example is given to verify the model.展开更多
