The cognitive role of concept variability

Mind &Language, EarlyView.
I present and defend concept variability, the view that concepts can admit of indefinitely many variations and changes in their representational contents without thereby losing their identity. I argue that the variability of concepts is central to their role in enabling cognition, and thus that a concept's content variability is, despite philosophical ...

How does religion influence an emerging nationalism? Evidence from the Kurdish context in Turkey

Nations and Nationalism, EarlyView.
Abstract Based on qualitative interviews with 66 Sunni Muslim Kurdish elites, this study reveals that Kurdish Islamic circles in Turkey are not monolithic, homogeneous or fixed. Some willingly or unwillingly maintain their Islamic identity as a primary reference point for self‐consciousness, motivation for collective action and political aspirations ...

Bifurcations of heteroclinic loop accompanied by pitchfork bifurcation [PDF]

Nonlinear Dynamics, 2012
In this paper, using the local coordinate moving frame approach, we investigate bifurcations of generic heteroclinic loop with a hyperbolic equilibrium and a nonhyperbolic equilibrium which undergoes a pitchfork bifurcation. Under some generic hypotheses, the existence of homoclinic loop, heteroclinic loop, periodic orbit and three or four heteroclinic

Control of Pitchfork and Hopf Bifurcations [PDF]

1992 American Control Conference, 1992
A multiple-scale analysis is used to determine the effect of a linear regulator with a small gain on systems which exhibit pitchfork or Hopf bifurcations in open loop.

A pitchfork bifurcation in the tatonnement process ★ [PDF]

Economic Theory, 1997
. This note extends the example of Gale (1963) by considering the continuous time tatonnement process for a class of two agent, two commodity exchange economies, parametrized by a number μ∈(0,1). We demonstrate that as the parameter passes a threshold value μ* the unique, globally stable competitive equilibrium loses local stability while two new ...

Stochastic perturbation of pitchfork bifurcations

Structural Safety, 1989
Abstract In this paper the sensitivity to random parametric pertubation of dynamical systems that exhibit a pitchfork bifurcation is investigated. The largest Lyapunov exponent is evaluated to study the stability of the trivial solution of the linearized system. The bifurcating solution is then studied by analyzing the mean energy of the system.
