Therefore,in Europe today,Marxism remains powerful only in the form of leftist populism among the"radical left",as social-democrats and socialists have been largely absorbed by the right. However,because the struggle for hegemony is not only a binary relationship but also a triangular relationship,the only conceivable emancipation strategy is the old Marxist one,which is both dual,popular class against ruling class,and triangular,between three social forces (plus the competent). In this way,the popular class can access itself competence-power by associating with the competent and putting them under its own hegemony.展开更多

To characterize the time-varying degradation rate, the degradation process is determined by a non-stationary Gamma process and the soft failure is encountered when it exceeds a predefined critical level. For the hard failure, a Cox’s proportional hazard model is applied to describe the hazard rate of the time to system failure. The dependent relationship is modeled by incorporating the degradation process as a time-varying covariate into the Cox’s proportional hazard model. To facilitate the health characteristics evaluation, a discretization technique is applied both to the degradation process and the monitoring time.All health characteristics can be obtained in the explicit form using the transition probability matrix, which is computationally attractive for practical applications. Finally, a numerical analysis is carried out to show the effectiveness and the performance of the proposed health evaluation method.展开更多

Under generalized progressively hybrid censoring with partially observed failure causes, the maximum likelihood estimators are established, and the approximate confidence intervals are also constructed via the observed Fisher information matrix.Moreover, Bayes estimates and highest probability density credible intervals are presented and the importance sampling technique is used to compute corresponding results.
