This study investigated the time course of spelling, and its influence on graphomotor execution, in a successive word copy task. According to the cascade model, these two processes may be engaged either sequentially or in parallel, depending on the cognitive demands of spelling. In this experiment, adults were asked to copy a series of words varying in(More)
The processing of syllables during the writing of isolated words has been shown to occur either before or during the writing of the word containing them. To demonstrate that this difference is related to graphomotor constraints, participants copied bi- and trisyllabic words three times, in four conditions where graphomotor constraints were gradually(More)
In this paper, we consider the problem of constructing confidence intervals for a population median when the underlying population is discrete. We describe seven methods of assigning confidence levels to order statistic based confidence intervals, all of which are easy to implement. A simulation study shows that, with discrete populations, it is possible to(More)
Past studies have shown the unstability of unstructured peer-to-peer networks and in particular Gnutella. Because of this unstability,q ueries in these networks are inefficient. Furthermore, to keep the network stable, the protocols used require huge bandwidth usage. One approach proposed by Gnutella conceptors is to create twoc lasses of servents: leaf(More)

Many empirical studies on credit spread determinants consider a single-regime model over the entire sample period and …nd limited explanatory power. We model the credit cycle independently from macroeconomic fundamentals using a Markov regime switching model. We show that accounting for endogenous credit cycles enhances the explanatory power of credit(More)
