A dynamic integration algorithm for an ensemble of classifiers
1999
Numerous data mining methods have recently been developed, and there is often a need to select the most appropriate data mining method or methods. The method selection can be done statically or dynamically. Dynamic selection takes into account characteristics of a new instance and usually results in higher classification accuracy. We discuss a dynamic integration algorithm for an ensemble of classifiers. Our algorithm is a new variation of the stacked generalization method and is based on the basic assumption that each basic classifier is best inside certain subareas of the application domain. The algorithm includes two main phases: a learning phase, which collects information about the qua…
Big Data as a Driver for Clinical Decision Support Systems: A Learning Health Systems Perspective
2018
Big data technologies are nowadays providing health care with powerful instruments to gather and analyze large volumes of heterogeneous data collected for different purposes, including clinical care, administration, and research. This makes possible to design IT infrastructures that favor the implementation of the so-called “Learning Healthcare System Cycle,” where healthcare practice and research are part of a unique and synergic process. In this paper we highlight how “Big Data enabled” integrated data collections may support clinical decision-making together with biomedical research. Two effective implementations are reported, concerning decision support in Diabetes and in Inherited Arrh…
The dependency of the validity of information integration on cognitive variables and the judgement task
1980
Simple models of information integration focus essentially on the combination of the components of information. This research investigated whether cognitive variables in the constructs of intelligence and cognitive complexity, as well as concentration, could predict the conditions of simple models of judgement. As additional predictors, the two qualitative variables [type of information] and [experience of the judgement task] were introduced. Subjects judged three types of stimuli using the pair comparison method. The conditions of the judgement models were analysed in the framework of the conjoint-measurement approach. Five different regression functions provided mediocre approximations to…
Audiovisual constructs of Paralympic Games : scalarity and camera angle
2014
This research will analyze the variables differentiating between the audiovisual television of the XIII edition of the Paralympic Games and the Games of the XXIX Olympiad, held in Beijing from the 7th of September to the 17th, 2008. This study will serve as a methodological basis for similar future research. By means of a qualitative and quantitative methodology, this study also focuses on determining if TV representations of Paralympic sportspersons favour their social integration or if, on the contrary, lead to higher stigmatization.
Ontological supports of knowledge: knowledge creation and analytical knowledge
2011
PurposeThe purpose of this paper is to examine, from the perspective of different theoretical approaches, the relationship that exists between different ontological supports of knowledge and knowledge itself (the way it is created and its characteristics).Design/methodology/approachThe paper proposes two different types of knowledge (knowledge of concrete situations and abstract knowledge) and two approaches (the constructivist view and the cognitive view) and provides a general classification of the different knowledge types. Second, it examines the underlying ontological support‐knowledge creation, characteristics or types of knowledge relationship in different approaches. Finally, conclu…
A new interface to couple thin-layer chromatography with laser desorption/atmospheric pressure chemical ionization mass spectrometry for plate scanni…
2005
An interface to allow on-line qualitative and quantitative full-plate detection and analysis of compounds separated by thin-layer chromatography (TLC) is presented. A continuous wave diode laser is employed as a desorption source. Atmospheric pressure chemical ionization mass spectrometry ionizes and subsequently identifies the desorbed sample molecules. Besides direct laser desorption on untreated TLC plates, graphite particles were used as a matrix to couple in the laser power and improve the efficiency of desorption.
Análisis de la sostenibilidad del sector exterior en la OCDE con técnicas de multicointegración
2022
Este artículo analiza la sostenibilidad externa de un grupo de 23 países de la OCDE durante el periodo 1970-2020. La estrategia empírica adoptada muestra la importancia del desequilibrio acumulado como desencadenante del ajuste externo, en línea con la propuesta de Gourinchas y Rey (2007). Para ello, contrastamos la sostenibilidad externa a través de la relación acumulado-flujo entre las variables que representan las relaciones externas de una economía abierta utilizando varios tipos de contrastes de cointegración y multicointegración. Los resultados obtenidos apuntan hacia la sostenibilidad en sentido débil en el análisis de los flujos, mientras que desde el punto de vista del enfoque acum…
New TEL Environments for Vocational Education – Teacher’s Instructional Perspective
2015
Modern vocational education is increasingly taking place in new technology-enhanced learning (TEL) settings. On the one hand, vocational education can benefit from the opportunities of technological development. On the other hand, such technologies may create new challenges for teachers. Therefore, there is a particular need to pay more attention to the dialogic pedagogical approaches in which teaching should be seen as a dialogical practice involving teacher-student interactions that create contextual opportunities for teachers to trigger students’ learning in new TEL settings. This article reports on an exploratory study about the different ways in which teachers’ instructional activities…
Differentiation, differentiated integration and disintegration in a ‘post-Brexit-era’
2019
In contrast to the ‘ever closer Union among the peoples of Europe’ invoked in the preamble of the Treaty of Rome, Frank Schimmelfennig and Thomas Winzen ponder whether the European Union (EU) is ‘growing ever looser’. Differentiation can take various forms which are often intertwined, such as functional, institutional, spatial/territorial as well as temporal differentiation. In 1998, Petersen studied Denmark’s integration policy in what he called a ‘dilemma’ between influence capability and stress sensitivity. With the Great Recession of 2007This introduction presents an overview of the key concepts discussed in the subsequent chapters of this book. The book 2008, the EU entered a new multi…
Les jeunes issus de l'immigration. De l'enseignement supérieur au marché du travail
2004
04038http://www.cereq.fr/pdf/b205.pdf; Souvent d'origine sociale défavorisée, les jeunes issus de l'immigration sont proportionnellement moins nombreux que les autres à poursuivre leurs études après le baccalauréat. Même lorsque tel est le cas, leur passage par l'enseignement supérieur ne parvient pas toujours à gommer le poids de leur origine, en particulier lorsqu'ils sont issus de l'immigration nord-africaine. Plus souvent confrontés au chômage, à la précarité de l'emploi, les jeunes d'origine maghrébine, et notamment les jeunes femmes, ont en effet plus de difficultés à entrer dans la vie active. Pour accéder à leur premier emploi, ils ont fréquemment recours à l'intérim, au travail sai…
