Smalltalk-80 also provides full closures with indefinite extent. These features pose interesting implementation challenges because a naïve implementation entails instantiating context objects on every method activation, but typical Smalltalk-80 programs obey stack discipline for the vast majority of activations. Both software and hardware implementations of Smalltalk-80 have mapped contexts and closure activations to stack frames but not without overhead when compared to traditional stack-based activation and return in “conventional” languages. We present a new design for contexts and closures that significantly reduces the overall overhead of these features and imposes overhead only in code that actually manipulates execution state in the form of contexts.Tue Apr 15 09:20:11 CEST 2008 Amsterdam Classification as a tool of research 169-176 Conceptual measurement and many--valued contexts 1986 measurement many--valued and Conceptual contexts Sat Apr 12 23:11:08 CEST 2008Proceedings of the 2nd Summer School on Generative and Transformational Techniques in Software Engineering (GTTSE 2007) (to appear)An Introduction to Context-oriented Programming with ContextS2007contexts Fri Nov 23 14:13:20 CET 2007Epistemologia, special issue on ``I Linguaggi e le Macchine''Also IRST Technical Report 9211-20, IRST, Trento, Italy.345--364Contextual ReasoningXVI1993contexts Thu Nov 08 15:41:39 CET 2007CONTEXTconf/context/2007206-219Lecture Notes in Computer ScienceThe Influence of Task Contexts on the Decision-Making of Humans and Computers.46352007humans agents decision LDSE multiagent modelling contexts cognition task Sun Oct 07 09:43:01 CEST 2007HeidelbergMathematical Knowledge Management: 4th International Conference, MKM 2005, Bremen, Germany, July 15-17, 2005, Revised Selected Papers33--48LNCSAuthoring Presentation for OpenMath38632006authoring, presentation, rendering, contexts content, notations, mathematical Some mathematical objects can have more than one notation. When a system compiles mathematical material from multiple sources, a management effort to maintain uniform and appropriate notations becomes necessary. Additionally, the need arises to facilitate the notations editing of the mathematical objects with authoring tools. In this paper, we present our work towards those needs. We have designed a framework that defines an authoring cycle supported by series of tools, which eases the creation of notations for the symbols in the process of publishing mathematics for the web.Fri May 04 05:48:10 CEST 2007May4543-05Multi-dimensional Ontology Views via Contexts in the {ECOIN} {S}emantic {I}nteroperability {F}rameworkWorking Paper2005single-ontology contexts with multiple This paper describes the coupling of contexts and ontologies for semantic integration in the ECOIN semantic interoperability framework. Ontological terms in ECOIN correspond to multiple related meanings in different contexts. Each ontology includes a context model that describes how a generic ontological term can be modified according to contextual choices to acquire specialized meanings. Although the basic ECOIN concepts have been presented in the past, this paper is the first to show how ECOIN addresses the case of "single-ontology with multiple contexts" with an example of semantic integration using our new prototype implementation.Wed Apr 18 11:38:06 CEST 2007Educational Studies in Mathematics1111--129Context Problems in Realistic Mathematics Education: A Calculus Course as an Example391999mathematics realistic education contexts Thu Apr 12 07:56:28 CEST 2007Educational Studies in Mathematics#dec#4341--373Encouraging the transfer of school mathematics to the real world through the integration of process and content, context and culture251993contexts real-world mathematics This paper reports upon a research project which considered the transfer of students' mathematical understanding across different task contexts. The research involved two groups of students from contrasting learning environments. The first environment was characterised by the complete integration of mathematical process and content using open ended activities. The second environment represented a lsquotypicalrsquo English classroom with a content based scheme being predominantly used. The research demonstrated that the procedure and performance of students in response to addition and fraction tasks varied considerably when the context of the tasks changed. This variation suggested that students' perceptions of the contexts were individually constructed and contexts did not have a uniform effect upon the difficulty of tasks. The research also suggested that students who had learned in an environment characterised by the integration of process and content were more able to transfer their learning across contexts. Students who had learned mathematical process independently of content were more likely to vary their procedure and performance in response to the contexts of the tasks. This was considered in relation to the problems of lsquoschoolrsquo — lsquoreal worldrsquo transfer and the effectiveness of different learning environments.Wed May 10 21:42:50 CEST 2006Information Systems Frontiers3257-272Language/Action Meets Organisational Semiotics: Situating Conversations with Norms.42002language/action contexts conversation norms semiotics Wed May 10 21:41:30 CEST 2006Proceedings of the Fifth International Conference on Conceptual Structures, University of Washington, Seattle, August 3--8, 1997Lecture Notes in Artificial Intelligence, No. 125780--94Contexts: A Formal Definition of Worlds of Assertions1997graphs conceptual contexts Thu Feb 02 17:51:21 CET 2006Proc. 3rd Intl.
