Expressing layer dependencies in Context-oriented Program-ming is cumbersome because until now no facility has been introduced to control the activation and deactivation of lay-ers. This paper presents a novel reflective interface that provides such control without compromising efficiency

ContextL is an extension to the Common Lisp Object System that allows for Context-oriented Programming. It provides means to associate partial class and method definitions with layers and to activate and deactivate such layers in the control flow of a running program. When a layer is activated

of students main effect, F(1, 4521) = 118.52, p < .0001. Results indicated that dropout students perceived themselves as significantly less competent in school activities than persistent students. A significant gender main effect was also revealed, F(l, 4521) = 6.42. p < .01. Female students perceived

PADS is designed to support context-aware processing by providing an executing platform to enable active service deployment and reconfiguration of the service composition in response to environments of varying contexts. Unlike most mobile middleware, MobiPADS supports dynamic adaptation at both the middleware

Abstract Many financial markets are characterized by strong relationships and networks, rather than arm's-length, spot-market transactions. We examine the performance consequences of this organizational choice in the context of relationships established when VCs syndicate portfolio company

(as captured by cameras and microphones). By defining a proper set of individual actions, group actions can be modeled as a two-layer process, one that models basic individual activities from low-level audio-visual features, and another one that models the interactions. We propose a two-layer Hidden

by ContextL, ContextJ*, and other languages. Our language is based on Featherweight Java extended with layers and scoped layer activation and deactivation. As layers may introduce methods not appearing in classes, we also give a static type system that ensures that no program gets stuck (i.e., there exists a

, methods for deliberating about the circumstances and consequences of those actions, and—when things go wrong—ways to reflect upon and debug the activity of previously invoked mental critics. Mental critics are arranged into six layers, the reactive, deliberative, reflective, self-reflective, self

Regions of reflections contain two semi-transparent layers moving over each other. This generates two motion vectors per pel. Current multiple motion estimators either extend the usual brightness consistency assumption to two motions or are based on the Fourier phase shift relationship. Both
