The Effect of Cognitive Bias Modification in the Attention Bias of Students With Test Anxiety

Abstract Introduction: Many of the students chr('39')educational problems, including academic failure and maladaptive behaviors, stem from exam anxiety caused by studentschr('39') cognitive bias. Cognitive bias modification can reduce attention biases students to be negative. Therefore, the purpose of the present study was to investigate the effectiveness of cognitive bias modification interven...

The Bott Periodicity Theorem

The Bott periodicity theorem is of fundamental importance in many areas of mathematics, from algebraic topology to functional analysis. It appears unexpectedly in different guises and I would like to explain some of these as well as the influence it has had on the development of different fields. I will concentrate on two roles that periodicity plays. First, periodicity allows one to deloop cla...

Poincaré Duality and Periodicity, Ii. James Periodicity

Let K be a connected finite complex. This paper studies the problem of whether one can attach a cell to some iterated suspension ΣK so that the resulting space satisfies Poincaré duality. When this is possible, we say that ΣK is a spine. We introduce the notion of quadratic self duality and show that if K is quadratically self dual, then ΣK is a spine whenever j is a suitable power of two. The ...
