Financing Georgia's Schools: A Primer

Georgia's nearly 1.5 million students make it the ninth largest state K-12 school system in the United States. Furthermore, Georgia has one of the fastest growing school enrollments in the nation, registering an increase of 12.2 percent between 1996 and 2002. Educating these students requires substantial financial resources. The purpose of this Primer is to explain how education in Georgia is financed and to point out some of the major school financing issues confronting the state. Report No.8

Stability of Fully Nonlinear Stokes Waves on Deep Water: Part 1. Perturbation Theory

We consider a full set of harmonics for the Stokes wave in deep water in the absence of viscosity, and examine the role that higher harmonics play in modifying the classical Benjamin-Feir instability. Using a representation of the wave coefficients due to Wilton, a perturbation analysis shows that the Stokes wave may become unbounded due to interactions between the Nth harmonic of the primary wave train and a set of harmonics of a disturbance. If the frequency of the nth harmonic is denoted Ꙍn = Ꙍ(1 ± ꭉ) then instability will occur if √2 k nn sn 0 \u3c ꭉ \u3c (n -1) ! subject to the disturbance initially having sufficiently large amplitude. We show that, subject to initial conditions, all lower harmonics will contribute to instability as well, and we identify the frequency of the disturbance corresponding to maximum growth rate

What can a mean-field model tell us about the dynamics of the cortex?

In this chapter we examine the dynamical behavior of a spatially homogeneous two-dimensional model of the cortex that incorporates membrane potential, synaptic flux rates and long- and short-range synaptic input, in two spatial dimensions, using parameter sets broadly realistic of humans and rats. When synaptic dynamics are included, the steady states may not be stable. The bifurcation structure for the spatially symmetric case is explored, identifying the positions of saddle–node and sub- and supercritical Hopf instabilities. We go beyond consideration of small-amplitude perturbations to look at nonlinear dynamics. Spatially-symmetric (breathing mode) limit cycles are described, as well as the response to spatially-localized impulses. When close to Hopf and saddle–node bifurcations, such impulses can cause traveling waves with similarities to the slow oscillation of slow-wave sleep. Spiral waves can also be induced. We compare model dynamics with the known behavior of the cortex during natural and anesthetic-induced sleep, commenting on the physiological significance of the limit cycles and impulse responses
