This paper uses a structural, large dimensional factor model to evaluate the role of ‘news’ shocks (shocks with a delayed effect on productivity) in generating the business cycle. We find that (i) existing small-scale VECM models are affected by ‘non-fundamentalness’ and therefore fail to recover the correct shock and impulse response functions; (ii) news shocks have a limited role in explainin...

Psychological investigations have led to considerable insight into the working of the human language comprehension system. In this article, we look at a set of principles derived from psychological findings to argue for a particular organization of linguistic knowledge along with a particular processing strategy and present a computational model of sentence processing based on those principles....

This paper presents a comparative study of spelling errors that are corrected as you type, vs. those that remain uncorrected. First, we generate naturally occurring online error correction data by logging users’ keystrokes, and by automatically deriving preand postcorrection strings from them. We then perform an analysis of this data against the errors that remain in the final text as well as a...

This article reports an investigation aimed at analyzing interactive model of executive functions, which seeks to explain the process followed by human beings correct their mistakes. The method was analysis based on structural equations, considering maximum likelihood around a that considered six functions. We worked with randomized sample 771 subjects (mean age = 39.86, SD 15.47; 50.5%, women,...

This paper evaluates the positioning performance of a single-frequency software GPS receiver using Ionospheric and Tropospheric corrections. While a dual-frequency user has the ability to eliminate the ionosphere error by taking a linear combination of observables, a single-frequency user must remove or calibrate this error by other means. To remove the ionosphere error we take advantage of the...
