Reasoning about Temporal Context using Ontology and Abductive Constraint Logic Programming

The underlying assumptions for interpreting the meaning of data often change over time, which further complicates the problem of semantic heterogeneities among autonomous data sources. As an extension to the COntext INterchange (COIN) framework, this paper introduces the notion of temporal context as a formalization of the problem. We represent temporal context as a multi-valued method in F-Logic; however, only one value is valid at any point in time, the determination of which is constrained by temporal relations. This representation is then mapped to an abductive constraint logic programming framework with temporal relations being treated as constraints. A mediation engine that implements the framework automatically detects and reconciles semantic differences at different times. We articulate that this extended COIN framework is suitable for reasoning on the Semantic Web.

Moderating effects of management control systems and innovation on performance. Simple methods for correcting the effects of measurement error for interaction effects in small samples

In the accounting literature, interaction or moderating effects are usually assessed by means of OLS regression and summated rating scales are constructed to reduce measurement error bias. Structural equation models and two-stage least squares regression could be used to completely eliminate this bias, but large samples are needed. Partial Least Squares are appropriate for small samples but do not correct measurement error bias. In this article, disattenuated regression is discussed as a small sample alternative and is illustrated on data of Bisbe and Otley (in press) that examine the interaction effect of innovation and style of use of budgets on performance. Sizeable differences emerge between OLS and disattenuated regression

Innovation strategies in the presence of technology markets: evidence from spanish innovative firms

The development of markets for technology has eased the acquisition of technology and reshaped the innovation strategies of firms that we classify as producers of innovations or as imitators. Innovative activities of firms include research, acquisition of technology and downstream activities. Within an industry, firms producing innovations tend to conduct more research and downstream activities than those imitating innovations. Acquisition of technology is equally important for both. To implement innovation strategies, firms producing innovations require both the capability to scan the external environment for technology and the capability to integrate new technology. Firms producing innovations require both, while firms imitating innovations require scan capabilities only

Innovation typology in tourism

Innovation is a research topic with a broad tradition. However, learning processes, from which innovations emerge, and the dynamics of change and development have traditionally been studied in relation with the manufacturing sector. Moreover, the objects of study have been usually process and tangible product innovations. Although recently researchers have focused their attention in other sectors, more research on service innovation should be carried out. Furthermore, regarding innovation in tourism, there is a need to adapt generic theories to the tourism sector and to contribute with new ideas. In order to find out, which are the origins of innovation processes, it is necessary to look into two fundamental subjects that are inherent to innovation, which are learning and interaction. Both are closely related. The first appears to be an intrinsic condition of individuals. Moreover, it can also be identified in organizations. Thus, learning allows individuals as well as organizations to develop. However, learning and development is not possible without taking the environment into account. Hence, it is necessary that interactions take place between individuals, groups of individuals, organizations, etc. Furthermore, the concept of interaction implies the transfer of knowledge, which is the basis for innovations. The purposes of this master thesis are to study in detail several of these topics and to develop a conceptual framework for the research on innovation in tourism

Une Innovation didactique basée sur les nanotechnologies au lycée: quels effets sur la dynamique professionnelle des enseignants?

Une nouvelle stratégie éducative a associé durant trois ans (2006-2009), au sein d’un lycée toulousain, enseignants du secondaire et chercheurs en sciences (CNRS-LAAS) et sciences humaines (ERT 64-GRIDIFE). Dans une classe de Terminale Scientifique, elle permet de combiner enseignement scientifique (mathématiques, physique-chimie, Sciences de la Vie et de la Terre) et enseignement aux « humanités » (philosophie, histoire-géographie-Éducation Civique, Juridique et Sociale (ECJS), anglais). Cette ingénierie d’éducation citoyenne des sciences repose sur l’enseignement des nanotechnologies. Ces dernières touchent de nombreux secteurs d’application et sont appelées à connaître un fort développement dans la société, engendrant de ce fait, de nombreux bouleversements en matière de développements économiques et industriels mais aussi de questionnements sur les relations entre sciences, technologies et société1. L’ingénierie d’éducation citoyenne aux sciences met l’accent sur la complémentarité entre formation scientifique et éthique pour éduquer les futurs citoyens à faire face à l’incertitude liée aux technosciences et leur impact sur la société (Désautels, 2002 ; Bensaude-Vincent, 2009)

Une Aide personnalisée pour le langage à l'école maternelle française: entre innovation et formation continue

De recentes directives ministerielles francaises (BO n° 25, 2008) ont impose aux enseignants de l'ecole primaire de consacrer deux heures par semaine de leur temps de travail a une Aide Personnalisee aux Eleves (APE). Au-dela des enjeux politiques et des tensions legitimes, s'est pose la question du contenu et de la pertinence de ces temps d'APE alors qu'aucun temps de formation supplementaire n'a ete prevu par le ministere. A l'ecole maternelle, l'objectif prioritaire etant la maitrise de la langue des eleves de trois a six ans, les APE peuvent theoriquement etre l'occasion pour les enseignants de mettre en place des situations d'interactions langagieres individualisees, ce qui est difficilement realisable avec le groupe classe. Neanmoins, reste la question de la conception et du contenu de ces temps d’echanges qui impliquent necessairement une reflexion sur les processus d’apprentissage du langage oral
