This research integrates and elaborates the basic premises of Blumer’s group position theory of prejudice. It does so in order to make explicit, more fully integrated, and empirically pliable the theoretical foundations of a sociological analysis of the nature of racial prejudice. In so doing, the research identifies important areas of agreement between Gordon Allport’s approach to prejudice an...

1. Introduction India has become one of the fastest growing economies in the world over the last two decades, arguably aided in this performance by economic reforms. One of the striking aspects of India's recent growth has been the dynamism of the service sector, particularly information technology (IT) and IT enabled services, while, in contrast, manufacturing has been less robust. The contrib...

We study the well-posedness of the Dirac-Klein-Gordon system in one space dimension with initial data that are analytic in a strip around the real axis. It is proved that for short times t the radius of analyticity σ(t) of the solutions remains constant while for |t| → ∞ we obtain a lower bound σ(t) ≥ c/|t|5+ in the case of positive Klein-Gordon mass and σ(t) ≥ c/|t|8+ in the massless case.

Knowledge Tracing is an extremely popular method for student modeling because of its capability to infer a student’s dynamic knowledge state in real time as the student is observed solving a series of problems (Corbett & Anderson, 1995). After its introduction in 1995, many extensions to the original technique have been proposed to improve its predictive accuracy. Variants include: fitting mode...

In this paper we consider the nonexistence of global solutions of a Klein-Gordon equation of the form utt −∆u+mu = f(u), (t, x) ∈ [0, T )× Rn. Here m = 0 and the nonlinear power f(u) satisfies some assumptions which will be stated later. We give a sufficient condition on the initial datum with arbitrarily high initial energy such that the solution of the above Klein-Gordon equation blows up in ...

The supersymmetric sinh-Gordon model on a half-line with integrable boundary conditions is considered perturbatively to verify conjectured exact reflection factors to one loop order. Propagators for the boson and fermion fields restricted to a half-line contain several novel features and are developed as prerequisites for the calculations.

The sine-Gordon equation has hyperelliptic al function solutions over a hyperelliptic Jacobian for y = f(x) of arbitrary genus g. This article gives an extension of the sine-Gordon equation to that over subvarieties of the hyperelliptic Jacobian. We also obtain the condition that the sine-Gordon equation in a proper subvariety of the Jacobian is defined.

We study the scattering theory for the coupled KleinGordon-Schrödinger equation with the Yukawa type interaction in two space dimensions. The scattering problem for this equation belongs to the borderline between the short range case and the long range one. We show the existence of the wave operators to this equation without any size restriction on the Klein-Gordon component of the final state ...

This paper investigates the occurrence of 'technology acceleration' across a range of information technologies. The prospect of technology was broached by Gordon Moore of Intel in 1965. His anecdotal 'law' – i.e. performance / price doubles every 18 months – has become received wisdom in many technology industries. Gilder popularized it as Moore’s law and proposed Gilder’s law and a number of s...
