This paper studies the causal e¤ect of aid volatility on the economic performance of developing countries in 2000-2009 period. We construct a time-varying measure of aid volatility using autoregressive conditional heteroskedasticity (ARCH). We control for the endogeneity of aid ‡ows by using as instruments for aid volatility three characteristics of donor counitres: (i) their budget de…cits ; (...

The memory bus must work. Given the current status of Bayesian archetypes, physicists particularly desire the exploration of Moore's Law. We describe a metamorphic tool for visualizing thin clients, which we call BETRIM. Keywords— sensor networks,memory bus,betrims,,DHCP

Many current approaches to statistical language modeling rely on independence a.~sumptions 1)etween the different explanatory variables. This results in models which are computationally simple, but which only model the main effects of the explanatory variables oil the response variable. This paper presents an argmnent in favor of a statistical approach that also models the interactions between ...

Let me answer this question unequivocally. It depends. Figured out I’m a consultant yet? Actually, let me explain. It does depend. It depends on what you think patterns are. Many people have a misunderstanding of patterns, and for those people, patterns can be harmful. However, when people get past their early understanding of patterns and come to comprehend them in a richer way, patterns canno...

The Test Vector Concept A test system based on vectors has several defining characteristics: • There is a “vector sequencer” that defines which “vector” will be obeyed next. • The vector sequencer broadcasts a small amount of information (such as vector address, period numbers and timeset numbers) to all of the pin channels. • The pin channels access a small pin command, usually of between 1 an...

Passing the Turing Test is not a sensible goal for Artificial Intelligence. Adherence to Turing's vision from 1950 is now actively harmful to our field. We review problems with Turing's idea, and suggest that, ironically, the very cognitive science that he tried to create must reject his research goal.

A central problem in the theory of genetic algorithms is the characterization of problems that are difficult for GAs to optimize. Many attempts to characterize such problems focus on the notion of Deception, defined in terms of the static average fitness of competing schemas. This article examines the Static Building Block Hypothesis (SBBH), the underlying assumption used to define Deception. E...

We model the stock market as a timing game, in which arbitrageurs who are not expected to be certainly rational compete over profit by bursting the bubble caused by investors’ euphoria. The manager raises money by issuing shares and the arbitrageurs use leverage. If leverage is weakly regulated, it is the unique Nash equilibrium that the bubble persists for a long time. This holds even if the e...

Frequently physical affordances are considered one of the main advantages of tangible interfaces or input devices, making interaction intuitive. This assumption may be overly simplistic – because physical objects have a multitude of physical affordances and properties, it is difficult for the designer to restrict these to (only) those that match with the digital system that they are connected w...
