A central organizing framework of the voluminous recent literature studying changes in the returns to skills and the evolution of earnings inequality iswhatwe refer to as the canonicalmodel, which elegantly and powerfully operationalizes the supply and demand for skills by assuming two distinct skill groups that perform twodifferent and imperfectly substitutable tasks or produce two imperfectly...

We examined the controlling factors that allow a prompted skill to become autonomous in a discrete-trials implementation of Touchette's (1971) progressively delayed prompting procedure, but our subjects were rats rather than children with disabilities. Our prompted skill was a left-right lever-press sequence guided by two panel lights. We manipulated (a) the effectiveness of the guiding lights ...

Why are performance trade-offs so rarely detected in animals when their underlying physiological basis seems so intuitive? One possibility is that individual variation in health, fitness, nutrition, development or genetics, or 'individual quality', makes some individuals better or worse performers across all motor tasks. If this is the case, then correcting for individual quality should reveal ...

Transfer (i.e., the application of a learned skill in a novel context) is an important and desirable outcome of motor skill learning. While much research has been devoted to understanding transfer of explicit skills the mechanisms of skill transfer after incidental learning remain poorly understood. The aim of this study was to (1) examine the effect of practice schedule on transfer and (2) inv...

flexibility is one of the most important indicators of a supply chain .a flexible supply chain in the face of market changes and customer needs, must be responsive to the changes and needs, to be able to attract customers in the a competitive marketplace. being aware of the flexibility of a supply chain helps managers to solve problems and overcome deficiencies and increase the competitive adva...

flexibility as an ability to respond to changing circumstances is one of the vital characteristics of the natural and built environment. during the contemporary era, diversity of methods relating the architectural flexibility execution are suggested. but along with contemporary conceptual approaches toward pluralism and uncertainty, it seems that the multiplicity of approaches toward flexibilit...

Wage inequality in the United States has grown substantially in the past two decades. Standard supply-demand analysis in the empirics of inequality (e.g. Katz and Murphy (1992)) indicates that we may attribute some of this trend to an outward shift in the demand for high skilled labor. In this paper we examine a simple static channel in which the wage premium for skill may grow increased firm e...
