The Living Gesture and the Signifying Moment

Drawing from Peircean semiotics, from the Greek conception of phronesis, and from considerations of bodily awareness as a basis of reasonableness, I attempt to show how the living gesture touches our deepest signifying nature, the self, and public life. Gestural bodily awareness, more than knowledge, connects us with the very conditions out of which the human body evolved into its present condition and remains a vital resource in the face of a devitalizing, rationalistic consumption culture. It may be precisely these deep-rooted abilities for what I term “self-originated experience” that can ultimately offset automatism

On the limit behaviour of second order relative spectra of self-adjoint operators

It is well known that the standard projection methods allow one to recover the whole spectrum of a bounded self-adjoint operator but they often lead to spectral pollution, i.e. to spurious eigenvalues lying in the gaps of the essential spectrum. Methods using second order relative spectra are free from this problem, but they have not been proven to approximate the whole spectrum. L. Boulton (2006, 2007) has shown that second order relative spectra approximate all isolated eigenvalues of finite multiplicity. The main result of the present paper is that second order relative spectra do not in general approximate the whole of the essential spectrum of a bounded self-adjoint operator
