Excerpt] In terms of the current discussion of pro-poor economic growth, the Harris-Todaro model and other multi-sector labor market models can help policy-makers avoid two mistakes. One is to assume that development efforts should necessarily be channeled to the sectors where the poor are. The other is to assume that efforts should necessarily be focused on getting the poor out of the sectors ...

In the category of operator spaces, that is, subspaces of the bounded linear operators B(H) on a complex Hilbert space H together with the induced matricial operator norm structure, objects are equivalent if they are completely isometric, i.e. if there is a linear isomorphism between the spaces which preserves this matricial norm structure. Since operator algebras, that is, subalgebras of B(H),...

The millennium marks the beginning of a second century for the formal system of juvenile justice in the United States. From its inception, the central focus of the system has been delinquency, an amorphous construct that includes not only “criminal” behavior but also an array of youthful actions that offend prevailing social mores. Thus, the meaning of delinquency is markedly time dependent. Li...

in this paper we study properties of symbols such that these belong to class of symbols sitting insidesm ρ,φ that we shall introduce as the following. so for because hypoelliptic pseudodifferential operatorsplays a key role in quantum mechanics we will investigate some properties of m−hypoelliptic pseudodifferential operators for which define base on this class of symbols. also we consider maxi...

In this paper we propose a method of corner detection for obtaining features which is required to track and recognize objects within a noisy image. Corner detection of noisy images is a challenging task in image processing. Natural images often get corrupted by noise during acquisition and transmission. Though Corner detection of these noisy images does not provide desired results, hence de-noi...
