A social humanoid robot as a playfellow for vocabulary enhancement

2018

We introduce a system that exploits a Pepper humanoid robot acting as a playfellow in a word-play game. The robot can play a portmanteau game by directly interacting with children, and it exploits a conversation engine, a portmanteau creation engine, and a definition engine. The humanoid can play the role of either an answerer or a generator of new words.

Portmanteau Word-Play for Vocabulary Enhancement with Humanoid Robot Support

2018

Word-play is as powerful learning and motivation tool often used by educators for teaching the ability of reading, which is a complex activity. In this paper, we introduce a system that exploits a Pepper humanoid robot acting as a playfellow in a word-play game based on portmanteau words. The robot shows the ability to play with children using a conversation engine, a portmanteau creation engine, and a definition engine. In this manner, Pepper can integrate itself within a group of kids, and it can support a teacher in her activities. The humanoid can be involved in a word-based round-game in which it can play the role of either answerer or generator of new words.

Development of pre-academic skills and motivation in kindergarten : a subgroup analysis between classroom quality profiles

2017

AbstractThe present study extends research on classroom quality profiles by examining the differences between profiles with respect to children’s development in pre-academic skills and motivation across the kindergarten year. Teacher–child interactions were observed in 49 Finnish kindergarten classrooms using the CLASS Pre-K instrument. Based on prior identification of latent profiles of classroom quality, subgroup analyses on children’s data were carried out on three profiles representing high Emotional Support and Classroom Organisation and intermediate Instructional Support (Profile 1), higher-intermediate Emotional Support and Classroom Organisation and lower-intermediate Instructional …

Vocational education approach: New TEL settings—new prospects for teachers' instructional activities?

2013

This study focuses on vocational education teachers’ instructional activities in a new technology-enhanced learning (TEL) setting. A content analysis is applied to investigate teachers’ and students’ interactions in a 3D game context. The findings illustrate that when teachers’ and students’ interactions are mediated by a game, teachers seem to apply different discussion activities to empower vocational learning than they do in traditional classroom settings. Additionally, the present study shows that teachers spontaneously develop new ways of supporting vocational learning processes. In more detail, two main types of instructional activities were identified: a “knowledge-providing” approac…

Learning at work : Researching personal development and competence building in work integration companies

2017

The context of our research is Work Integration Enterprises. These hire people who are emerging from processes of social exclusion for a period of between 6 months and three years. In these companies, people work while learning a trade and learning to work, in order to facilitate their entry into the ordinary labour market.Of the different academic approaches to processes of learning at work and training, we have chosen Michael Eraut's notion of learning trajectories to apply to our research. We have chosen it for its potential: it provides a longitudinal approach to learning, it takes into account technical, social and personal dimensions of learning, and it also develops a particular focu…

Chapter 7 - Sensory interactions in wine: effect of nonvolatile molecules on wine aroma and volatiles on Taste/Astringency perception

2012

International audience; It is widely accepted that sensory interactions can, and do, occur during wine consumption. To this concern, many studies have dealt with aroma-taste interactions which have been attributed to physicochemical interactions in the product itself, interactions at the receptor level or cognitive interactions. Although the understanding of these interactions has grown during last years and it has been demonstrated that they are strongly product-dependent, investigations have seldom gone beyond that of model solutions with a reduced number of components (volatile and/or nonvolatile molecules). Recently some investigations carried out in this field have been conducted with …

Numerical and experimental study of hydrostatic displacement machine

2012

This paper presents a simulation tool to determine the structural deflections and corresponding leakage flow in a hydrostatic displacement motor. The simulation tool is applied to a new motor principle that is categorized as an extreme low-speed high-torque motor with dimensions that calls for attention to the volumetric efficiency. To counteract structural deflections the motor is equipped with compensation pressure volumes that may be used to limit the leakage flow across the end faces of the circular rotor. This leakage flow is investigated by solving Reynolds equation for the pressure distribution across both end faces. The fluid pressure is combined with structural calculations in a fl…

Constraining the spin-dependent WIMP-nucleon cross sections with XENON1T

2019

We report the first experimental results on spin-dependent elastic weakly interacting massive particle (WIMP) nucleon scattering from the XENON1T dark matter search experiment. The analysis uses the full ton year exposure of XENON1T to constrain the spin-dependent proton-only and neutron-only cases. No significant signal excess is observed, and a profile likelihood ratio analysis is used to set exclusion limits on the WIMP-nucleon interactions. This includes the most stringent constraint to date on the WIMP-neutron cross section, with a minimum of 6.3 × 10−42 cm2 at 30 GeV/c2 and 90% confidence level. The results are compared with those from collider searches and used to exclude new paramet…
