), and consumption-based macroeconomic ratios (cay). Our paper comprehensively reexamines the performance of these variables, both in-sample and out-of-sample, as of 2005. We find that [a] over the last 30 years, the prediction models have failed both in-sample and outof-sample; [b] the models are unstable

that is introduced here, referred to as the shifting strategy, is applicable to numerous geometric covering and packing problems. The method of using the technique and how it varies with problem parameters are illustrated. A similar technique, independently devised by B. S. Baker, was shown to be applicable

Abstract. We define a class of dynamical systems on the sphere analogous to the baker map on the torus. The classical maps are characterized by dynamical entropy equal to ln 2. We construct and investigate a family of the corresponding quantum maps. In the simplest case of the model the system does

Pretheoretically, there are processes in languages of the world that have both a syntactic component and a morphological component. An example is the English passive, illustrated in (1): (1) a. The cats chase the mouse every day. b. The mouse is chased by the cats every day. (lb) differs from (la

-size indexes and conventional values for these are given for operationally defined small, medium, and large effects. The sample sizes necessary for .80 power to detect effects at these levels are tabled for eight standard statistical tests: (a) the difference between independent means, (b) the significance

This paper describes our initial research into the use of the P300 event related potential as a control signal in a computer interface for locked-in patients. These experiments are directed toward development of a device which uses the occurrence of a P300 to control motion of a cursor on a computer screen. Simultaneous target-detection tasks are presented in four compass positions (N, E, S, W) on a computer screen. The subject is instructed to detect targets in one of the positions corresponding to the intended direction of cursor movement. EEG signals from scalp electrodes at Fz, Cz and Pz are collected and averaged for targets in each of the four locations and the direction of movement is indicated by the highest P300 peak amplitude. Variables such as target on-time, ISI, nulltarget inclusion, and trial averaging are manipulated and the results are discussed in terms of a rate vs. accuracy trade-off.

and specifically using some of Foucault's own terminology: a) An historical or 'technico-political' account of the rise of the school, from its negatively oriented seventeenth century origins to its more positively conceived nineteenth century entrenchment and expansion; b) an explication
