Therefore, in the process of establishing and implementing social security system, the status of the accounting system of social security fund has become particularly prominent. The existing problems in the system were discussed and corresponding reform ideas were proposed by analyzing the current situation of the social security fund accounting system.展开更多

In this paper, the process of IT project decision and implementation is fully analyzed, the real options that may be embedded in an IT project are identified, and a real option analysis (ROA) method is proposed for evaluation of an IT project under uncertain business environment. ROA employs Black-Scholes expansion model and cancels the assumption that the cost of project is certain. The numerical example manifests that the ROA can better evaluate IT project and select the IT investment alternative. Finally, a road map is provided to help selecting the suitable evaluation method to make IT investment decision.展开更多

In her 57-year publishing career, Lessing always crosses the borders: as a feminist or anti-feminist, as a science fiction writer or a realist who lost her way, as a Marxist or a reactionary, as a British writer or a postcolonial one. Lessing’s border-crossing not only lies in her different genres of writing or in different novels, but even in a single comparatively traditional novel. The Summer Before the Dark is a representative work of Lessing’s women portrayal transition from focusing on their outside world exploration to on their inner world seeking. This essay tries to look at the content and form of the novel, and to illustrate that Lessing’s border-crossing is also fulfilled in one single novel. She successfully crosses the border of convention and innovation: conventional in content, while innovative in form.展开更多

By considering the neurobiological phenomenon in brain development and the difference of the synaptic strength, we construct weighted networks develop with link additions and followed by selective edge removal. The network exhibits the small-world and scale-free properties with high network efficiency. The model displays an avalanche activity on a power-law distribution. We investigate the effect of selective edge removal and the neuron refractory period on the self-organized criticality of the system.展开更多

Because of the unique nature of these films, primarily which they are set in a future and distant world, they allow us to explore the socio-political landscape in which they were created from a remove that does not exist in "real-world" based works. Specifically we will be examining the governing power (in any particular Mars-based science fiction film) that might be either wielded by business interests or governmental interests. Although it is possible to have both a strong government and a strong business in a society, in many Mars-based science fiction films, government and business seem to represent two sides of a continuum. The stronger the business power structure in the film, the weaker the governmental power structure, and vice-versa.展开更多

As the thought of higher education management theory or a form, we jump out of the labyrinth of modernism manages view and the introduction of totally different from the modernist paradigm, from the angle of the theory research of postmodernism manages view. The paper is organized as the follows. In the first section, we generally introduce the basic concepts of higher education management and the relationship of the schools and government. Then, by comparing the pattern of the Chinese and the American, we analyze the difference in detail. Finally, we set up the prospect and the conclusion. In conclusion, our method combines the advantages of the American higher education management model which will be meaningful.展开更多

In the specific field of English literature, the genre of the fantastic is undoubtedly a common presence. In Fantasy: The Literature of Subversion, Jackson (1981) noted the re-emergence of the fantastic as a transgressive force at moments of cultural stress and repression. Waugh (1995) held a similar view in The Harvest of the Sixties. At the end of the 20th century, in its postmodernist shape, fantastic literature becomes one of the favourite genres of a number of feminist writers, and among them, Jeanette Winterson transforms it into a truly transgressive genre. This paper examines Winterson's The Passion (1996) and Sexing the Cherry (1990) in the light of Jackson's theory of the fantastic, as a narrative that establishes an oppositional dialogic relationship with the "real", to interrogate it and collapse the traditional distinction between the normative and the "other". In The Passion, the real is signified by the dominant ideological discourse, exemplified by Napoleon; the fantastic by Villanelle's webbed feet and her ability to walk on water. In Sexing the Cherry, the real is represented by the Puritans with their bigoted and hypocritical morality; the fantastic by the huge Dog-Woman and her foundling son, Jordan. Besides, in both novels, the female body is metamorphosed to challenge the view of a "normal", acceptable femininity; what emerges is a monstrous and sublime body that collapses distinctions between gender boundaries. In Sexing the Cherry (1990), Winterson created the grotesque, gigantic body of the Dog-Woman, a figure of Kristevan "abjection". In The Passion (1996), she gave life to the hybrid body of Villanelle, an oxymoronic combination of the terrible beautiful. The conclusion of the paper argues that Winterson deploys the fantastic to deconstruct the gendered subject of the dominant signifying order and create a dislocated world outside commercial culture, where new voices can be heard, speaking for unheard, neglected groups, particularly women.展开更多

The logical improvement was brought forward and the phenomenon of stress concentration was deceased by weighted analysis. The effects of different cut velocities and cutting thickness on life-spans of reamers were investigated, and the cutting parameters were optimized to satisfy the cutting precision and cutting efficiency. The study will provide a guide for the practical production.展开更多

Consensus can be achieved under some circumstances. But when the group reach consensus with a convergent opinion value which is not what we expect, how can we intervene the system and change the convergent value? In this paper a mechanism named soft control is first introduced in opinion dynamics to guide the group's opinion when the population are given and evolution rules are not allowed to change. According to the idea of soft control, one or several special agents,called shills, are added and connected to one or several normal agents in the original group. Shills act and are treated as normal agents. The authors prove that the change of convergent opinion value is decided by the initial opinion and influential value of the shill, as well as how the shill connects to normal agents. An interesting and counterintuitive phenomenon is discovered: Adding a shill with an initial opinion value which is smaller(or larger) than the original convergent opinion value dose not necessarily decrease(or increase) the convergent opinion value under some conditions. These conditions are given through mathematical analysis and they are verified by the numerical tests. The authors also find out that the convergence speed of the system varies when a shill is connected to different normal agents. Our simulations show that it is positively related to the degree of the connected normal agent in scale-free networks.展开更多
