We study incremental wave propagation for what is seemingly the simplest boundary value problem, namely that constitued by the plane interface of a semi-infinite solid. With a view to model loaded elastomers and soft tissues, we focus on incompressible solids, subjected to large homogeneous static deformations. The resulting strain-induced anisotropy complicates matters for the incremental boun...

This paper makes three main points. Fiscal policy, …rst, may be needed in the long run to maintain full employment and avoid secular stagnation. If …scal policy is used in this way, second, the long-run debt ratio depends (i) inversely on the rate of growth, (ii) inversely on government consumption, and (iii) directly on the degree of inequality. The analysis, third, suggests that policies and ...

Recent high-profile corporate scandals are reminiscent of the corporate raider scandals of the 1980s, suggesting that ethical scandals may occur in waves. This article provides a framework for analysis of this question by suggesting that ethical attitudes may be cyclical about long-term secular trends. We provide some empirical evidence from previously published work for the existence of cycles...

In order to analyze and model the body kinematics used by fish in a wide range of swimming behaviors, we developed a technique to separate the periodic whole-body motions that characterize steady swimming from the secular motions that characterize changes in whole-body shape. We applied this harmonic analysis technique to the study of the forward and backward swimming of lamprey. We found that ...

In the fi rst great period of bourgeois hegemony, the reinvention of romance fi nds its strategies in the substitution of new positivities (theology, psychology, the dramatic metaphor) for the older magical content. When at the end of the nineteenth century the search for secular equivalents seems exhausted, the characteristic indirection of a nascent modernism, from Kafka to Cortazar, circumsc...

The study was conducted on Punjabi Arora girls (n = 159) and their mothers to see the phenomenon of secular trend in stature and age at menarche. An increase in stature and decrease in age at menarche was reported when the data of daughters was compared with that of their mothers thereby indicating secular trend in these two parameters. Better living conditions, improved nutrition and medical f...

The comparative approach regarding the ethics of surrogacy from the Western secular and Islamic bioethical view reveals both commensurable and incommensurable relationship. Both are eager to achieve the welfare of the mother, child and society as a whole but the approaches are not always the same. Islamic bioethics is straightforward in prohibiting surrogacy by highlighting the lineage problem ...

In this note we discuss a method of order 1 + √ 3 for computing the smallest eigenvalue λ1 of a symmetric and positive definite Toeplitz matrix. It generalizes and improves a method introduced in [7] which is based on rational Hermitean interpolation of the secular equation. Taking advantage of a further rational approximation of the secular equation which is essentially for free and which yiel...

We show that the algorithm proposed by Gauss to compute the secular evolution of gravitationally interacting Keplerian rings extends naturally to softened gravitational interactions. The resulting tool is ideal for the study of the secular dynamical evolution of nearly Keplerian systems such as stellar clusters surrounding black holes in galactic nuclei, cometary clouds, or planetesimal discs. ...
