Children's creative potential: An empirical study of measurement issues     

Todd Lubart  Chantal Pacteau  Anne-Yvonne Jacquet  Xavier Caroff 《Learning and individual differences》2010,20(4):388-392

Relations between measures of creative potential and different scoring methods were examined in 154 French schoolchildren. The Test for Creative Thinking — Drawing Production (TCT-DP), parallel lines task from the Torrance Test for Creative Thinking, and an object-based creative drawing task were used. Factor analysis of TCT-DP subscores showed an originality factor and an appropriateness factor. The relations between these factors, judge's creativity ratings of the same drawings, and statistical originality scores based on the frequency of elements in the drawings were tested by means of a LISREL model. Moreover, TCT-DP scores correlated positively but weakly with performance in the parallel lines task and the object-based drawing task.  相似文献

Reacting to poverty: A comparative analysis of schools in Brazilian deprived areas     

Aina Tarabini  Xavier Bonal  Oscar Valiente 《Prospects》2014,44(3):335-349

Schools in the most deprived areas in Brazil are marked by extreme poverty, a situation that has obvious consequences for the everyday life in schools and for efforts to develop a supportive culture of schooling. Nevertheless, schools’ responses to poverty are far from uniform. Although the context of poverty generally determines what is possible for schools to achieve, this context is by no means consistent. Not all schools located in poor areas offer poor education. And, in themselves, unfavourable contexts do not necessarily generate educational failure. This article captures the diversity of effects generated by poverty at the school level, and the variety of responses by schools situated in very similar socioeconomic and cultural contexts. It draws on a study conducted in the state of Minas Gerais, which explored five schools and their corresponding cultures to reveal the diverse effects of poverty at the school level.  相似文献   

Pedagogical innovation and music education in Spain: Introducing the Dalcroze method in Catalonia     

Francesca Comas Rubí  Xavier Motilla-Salas  Bernat Sureda-Garcia 《Paedagogica Historica: International Journal of the History of Education》2014,50(3):320-337

The aim of this paper is to analyse how the Dalcroze method was introduced to Spain and became known there, more specifically in the Catalonia of the Noucentisme movement, and why it made the greatest impact and was more widely disseminated in this particular region of Spain. Following a summary of Dalcroze’s contributions to music education, an outline is given of how the Junta para la Ampliación de Estudios or Committee for Extended Studies (the JAE, in Spanish) became a springboard for the method’s introduction in Catalonia through a grant awarded to Catalan musician and teacher Joan Llongueras Badía, even though the JAE had not shown much interest in its diffusion. It goes on to explain how the method’s use spread in Catalonia, partly thanks to the efforts of Joan Llongueras and his Institute for Rhythmic Gymnastics and partly as a result of the support that these efforts received in the political, philosophical, moral and aesthetic context of the Noucentisme movement – which, the paper argues, explains why the method’s impact was much greater in Catalonia than in the rest of Spain.  相似文献   

Consumer Information Requirements and Telecommunications Regulation     

Patrick Xavier 《The Information Society》2013,29(5):342-354

Consumers can be disadvantaged and suffer detriment when information is withheld, when there is deception in the information provided, or when information is too difficult for consumers to obtain or evaluate. While information provision is often favored as a policy/regulatory tool to address “market failure,” it can have its own failings and drawbacks. For instance, the volume of information presented can contain its effectiveness. While the demand-side analysis indicates that actual consumer behavior exhibits systematic departures from the “rational” behavior assumed by conventional (neoclassical) economics, behavioral economics goes further in questioning whether additional information is always useful. It challenges some of the presumptions of conventional economics that consumers make their choices coherently and rationally. This article incorporates such considerations in proposing measures (including regulatory initiatives) that could improve the information made available to telecommunications consumers.  相似文献   

FIDJI: using syntax for validating answers in multiple documents     

Véronique Moriceau  Xavier Tannier 《Information Retrieval》2010,13(5):507-533

This article presents FIDJI, a question-answering (QA) system for French. FIDJI combines syntactic information with traditional QA techniques such as named entity recognition and term weighting; it does not require any pre-processing other than classical search engine indexing. Among other uses of syntax, we experiment in this system the validation of answers through different documents, as well as specific techniques for answering different types of questions (e.g., yes/no or list questions). We present several experiments which show the benefits of syntactic analysis, as well as multi-document validation. Different types of questions and corpora are tested, and specificities are commented. Links with result aggregation are also discussed.  相似文献   

Gradual refinement for application-specific MPSoC design from Simulink model to RTL implementation   总被引：1，自引：0，他引：1  

Kai Huang  Xiao-lang Yan  Sang-il Han  Soo-ik Chae  Ahmed A. Jerraya  Katalin Popovici  Xavier Guerin  Lisane Brisolara  Luigi Carro 《浙江大学学报(A卷英文版)》2009,10(2):151-164

The application-specific multiprocessor system-on-chip （MPSoC） architecture is becoming an attractive solution to deal with increasingly complex embedded applications, which require both high performance and flexible programmability. As an effective method for MPSoC development, we present a gradual refinement flow starting from a high-level Simulink model to a synthesizable and executable hardware and software specification. The proposed methodology consists of five different abstract levels： Simulink combined algorithm and architecture model （CAAM）, virtual architecture （VA）, transactional accurate architecture （TA）, virtual prototype （VP） and field-programmable gate array （FPGA） emulation. Experimental results of Motion-JPEG and H.264 show that the proposed gradual refinement flow can generate various MPSoC architectures from an original Simulink model, allowing processor, communication and tasks design space exploration.  相似文献   

Oxidative stress in elite athletes training at moderate altitude and at sea level     

Josefa León-López  Carmen Calderón-Soto  Matías Pérez-Sánchez  Belén Feriche  Xavier Iglesias  Diego Chaverri 《European Journal of Sport Science》2018,18(6):832-841

Using a controlled parallel group longitudinal trial design, we investigated the effects of different training interventions on the prooxidant/antioxidant status of elite athletes: living and training at moderate altitude for 3 (Hi-Hi3) and 4 weeks (Hi-Hi), and for 4 weeks too, living high and training high and low (Hi-HiLo) and living and training at sea level (Lo-Lo). From 61 swimmers, 54 completed the study. Nitrites, carbonyls, and lipid peroxidation (LPO) levels were assessed in plasma. Enzymatic antioxidants glutathione peroxidase (GPx) and glutathione reductase (GRd), and non-enzymatic antioxidants total glutathione (GST), reduced glutathione (GSH) and oxidized glutathione (GSSG) were analysed in the erythrocyte fraction. At the end of the intervention, nitrites levels were similar in all altitude groups but higher than in the Lo-Lo controls (P?=?.02). Hi-HiLo had greater GPx activity than Hi-Hi and Hi-Hi3 during most of the intervention (P?≤?.001). GRd activity was higher in Lo-Lo than in Hi-Hi at the end of the training camp (P?≤?.001). All groups showed increased levels of LPO, except Lo-Lo, and carbonyls at the end of the study (P?≤?.001). Training at altitude for 3 or 4 weeks drives oxidative stress leading to cellular damage mainly by worsening the antioxidant capacities. The GSSG/GSH ratio appears to be related to perceived exertion and fatigue. The stronger antioxidant defence showed by the Hi-HiLo group suggests an inverse relationship between redox alterations and performance. Further studies are required to investigate the role of oxidative stress in acclimatization, performance, and health.  相似文献
