The result of the MFDFA shows that there exists obvious multifractal scaling behavior in produced time series. We compare the MFDFA results for original time series with those for shuffled series, and find that its multifractal nature is due to two factors: broadness of probability density function of the series and different correlations in small- and large-scale fluctuations. This may provide new insight to the problem of the origin of multifractality in financial time series.展开更多

A refined finite element model was developed to conduct full-process analysis of construction of super-high rise buildings like Shanghai World Financial Center, in which the discrete analysis method of time-varying structures and age-adjusted effective modulus method were both used. In the finite element analysis, the whole construction process was divided into a series of stages, each with a structural system that is a part of the whole structure and with different material parameters, geometrical parameters, loading and boundary conditions. The whole construction process of Shanghai World Financial Center in consideration of creep of concrete was simulated successfully by using the finite element model and the analytical method developed. With respect to different construction stage, the total vertical deformation, inter-floor compression deformation and the relative deformation between the outer frame and the core-wall were obtained through the analysis. The comparison between the results from the stage-wise full-process analysis of construction with and without considering the creep and the results from the conventional analysis of the whole building under the total load from all self-weight and construction applied to the structure "in one go" shows that the cumulative effect on the deformation from the construction process and the creep effect need to be considered in analyzing the deformation of Shanghai World Financial Center, and the super-high rise buildings suchlike. Finally, the simulation results correlate well with the monitoring results-a proof of the feasibility and the validity of this paper.展开更多

Profit-driven financial voluntarism is spreading everywhere, leading directly to the "financial internalization" of individual lives and the decline of the holistic spirit in human life. World development is inseparable from financial innovation, but the present financial system has diverged from its true nature. Undeniably, capital's innate quest for surplus value has not changed since Marx's times, nor have its essential social relations or the leverage effect of capital in wealth creation. However, the 21st century has seen a great change in the development of the logic of capital: driven by the global capital financial system, it has become more abstract, overriding regional boundaries. Its subject orientation is heterogeneous and diverse, while its operating mode is virtual and enigmatic. In particular, as instrumental rationality has become more intelligent, the mental dimension of capital has become more subjective. An interpretation of the financialized world from the point of view of phenomenology of spirit reveals the underlying issue of the alienation of man's spirit from his objectified world in the 21st century, and thus offers food for thought at the level of spirit for the objective understanding of the category of capital in the 21 st century,展开更多

文摘We present a multifractal detrended fluctuation analysis (MFDFA) of the time series of return generated by our recently-proposed Ising financial market model with underlying small world topology. The result of the MFDFA shows that there exists obvious multifractal scaling behavior in produced time series. We compare the MFDFA results for original time series with those for shuffled series, and find that its multifractal nature is due to two factors: broadness of probability density function of the series and different correlations in small- and large-scale fluctuations. This may provide new insight to the problem of the origin of multifractality in financial time series.
