Motivation – To analyse how Augmented Reality associated to video may affect collaborative design and multimodal interactions. Research approach – An exploratory study that aims to compare 2 pairs of last year students in co-presence with 1 distant pair. Each pair had to solve an architectural design problem. Collected video has been coded with a systematic method of protocol analysis. Findings/Design – When using an AR desktop-based CAD, distance may not affect the design process itself whereas it may affect how the process is distributed across the various modalities of collaboration. Furthermore, collaborating and architectural experiences influence collaboration and/or design. Research limitations/Implications – Only 3 pairs of students participated in the study resulting in 12 h of video protocol, which limits generalisation of the findings. Originality/Value – The research makes a contribution in providing a detailed view on how external (e.g. situation, technology) and individual factors may affect the activity of collaborative design. Furthermore, we propose a coding method usable beyond design in a wide range of collaborative activities to underline how they are affected by technology and other situational constraints. Take away message – Technology constraints as well as personnal characteristics of designers result in designing with specific forms of multimodal collaboration. [less ▲]

This work aimed to describe a mechanistic model for soil heterotrophic respiration, to apply it to an agricultural soil and to specify its important parameters, in order to define future research fields. A complete description of the model structure is given. It uses a daily time step and is derived from the CENTURY model. The model was found to be independent from the initial carbon pool contents and an exponential relationship was observed between the order of stabilisation of the different pools and their respective decomposition constants. Literature was scanned to provide a panel of biochemical parameter values (nitrogen, lignin, cellulose and hemicellulose contents) for wheat, sugar beet and potato crops. Large parameter ranges of values were noticed and a lack of information about sugar beet and potato crops drove our choice to work with wheat biochemical parameters later on. An exponential relationship between two parameters linked to the effect of temperature on microbial respiratory activity, respectively Tb and h, was highlighted. For a fixed value of Q10, the values of these two parameters varied in opposite ways. The sensitivity analysis was performed at both short and long terms, mainly on the basis of carbon pool contents. The results were very variable from one pool to another. In both analyses Tb and h appeared to be the most sensitive parameters while some differences between both time spans were noticed, notably because of pool stabilisation dynamics and crop residue types. In the end, the combination of sensitivity values with parameter ranges of values brought us to consider the parameters Tb, h, Nlit (% nitrogen in above-ground residues) and Lignlit (% lignin in above-ground residues) and the forcing variables MBR (root residues quantity) and Litfall (above-ground residues quantity) as the features about which further investigations would be needed. The integration of this mechanistic model into a more complete one, also taking account of autotrophic respiration and CO2 diffusion in soils, is a further goal to achieve. [less ▲]

To accompany the International Classification of Primary Care (ICPC), a new classification called Core Content Classification in General Practice Family Medicine (3CGP/FM) is proposed in order to index documents pertaining to the domain of expertise of GP/GM. The tool and its construction are described and their purpose discussed. 3CGP/FM, which is also complementary to Medline, permits the indexing of Wonca congress presentations and allows a quick view of the main axes of research of GP/FM. A desk copy of 3CGP/FM is available on the Wonca abstracts repository project web site and in attached file. [less ▲]

In a previous study, Parisse suggested that subject dislocations in French language (e.g. "la fille elle dort") could be considered as a marker of morphosyntactic development in children with normal language development. The present study aimed to develop this proposition and to confirm it with experimental data, more specifically the fact that this development would go through a four-step process. Our prediction was that children could produce forms that correspond to successive steps in the developmental process (for example, forms [1] and [2], or [2] and [3]), but not forms that were very different (for example, forms [1] and [4], or [2] and [4]). In order to test this hypothesis, a sentence repetition task was administrated to 27 children aged 4 to 5. The results confirm the presence of a developmental trend in the use of dislocation in spontaneous language. At age 4, dislocations were frequent (30%), and tended to respect the gender (stage 3 and 4). At age 5, dislocations were rare (stage 4). Previous stages (1 and 2) would be observed in younger children. [less ▲]

Cette communication s’inscrit dans le cadre du projet Elfe et vise à évaluer l’impact d’une formation à distance pour femmes créatrices et chefs d’entreprise sur leur sentiment d’efficacité personnelle, tel que défini par Bandura (1997). Nous situons notre intervention par rapport aux premier et deuxième niveaux d’évaluation d’une formation selon Kirkpatrick (1983), se rapportant respectivement à la satisfaction des apprenants et à leurs acquis, avec une attention particulière au sentiment d’efficacité personnelle. Notre méthodologie de recherche qualitative est basée sur dix études de cas approfondies auprès de femmes futures créatrices et chefs d’entreprise. Les résultats en termes de satisfaction des apprenantes sont nuancés et mettent en évidence différents éléments de contexte. Par contre, l’étude révèle qu’au terme de la formation à distance, les femmes entrepreneures de notre échantillon ont vu leur sentiment d’efficacité personnelle augmenter. Nous identifions différents facteurs explicatifs. Enfin, l’analyse met en évidence certains éléments relatifs au troisième niveau de Kirkpatrick, le transfert sur le terrain, ouvrant ainsi la route à de nouvelles pistes de recherche. Les implications managériales sont importantes. En effet, il nous semble crucial que notre formation s’inscrive dans une vision à long terme et, au-delà de développer les connaissances et compétences, contribue aussi et surtout à renforcer le sentiment d’efficacité personnelle des apprenantes par rapport à leurs capacités entrepreneuriales, facteur déterminant pour la performance présente et future de leurs entreprises.

The Atmospheric Chemistry Experiment (ACE), also known as SCISAT, was launched on 12 August 2003, carrying two instruments that measure vertical profiles of atmospheric constituents using the solar occultation technique. One of these instruments, the ACE Fourier Transform Spectrometer (ACE-FTS), is measuring volume mixing ratio (VMR) profiles of nitrous oxide (N2O) from the upper troposphere to the lower mesosphere at a vertical resolution of about 3-4 km. In this study, the quality of the ACE-FTS version 2.2 N2O data is assessed through comparisons with coincident measurements made by other satellite, balloon-borne, aircraft, and ground-based instruments. These consist of vertical profile comparisons with the SMR, MLS, and MIPAS satellite instruments, multiple aircraft flights of ASUR, and single balloon flights of SPIRALE and FIRS-2, and partial column comparisons with a network of ground-based Fourier Transform InfraRed spectrometers (FTIRs). Between 6 and 30 km, the mean absolute differences for the satellite comparisons lie between -42 ppbv and +17 ppbv, with most within +/- 20 ppbv. This corresponds to relative deviations from the mean that are within +/- 15%, except for comparisons with MIPAS near 30 km, for which they are as large as 22.5%. Between 18 and 30 km, the mean absolute differences for the satellite comparisons are generally within +/- 10 ppbv. From 30 to 60 km, the mean absolute differences are within +/- 4 ppbv, and are mostly between -2 and +1 ppbv. Given the small N2O VMR in this region, the relative deviations from the mean are therefore large at these altitudes, with most suggesting a negative bias in the ACE-FTS data between 30 and 50 km. In the comparisons with the FTIRs, the mean relative differences between the ACE-FTS and FTIR partial columns (which cover a mean altitude range of 14 to 27 km) are within +/- 5.6% for eleven of the twelve contributing stations. This mean relative difference is negative at ten stations, suggesting a small negative bias in the ACE-FTS partial columns over the altitude regions compared. Excellent correlation (R=0.964) is observed between the ACE-FTS and FTIR partial columns, with a slope of 1.01 and an intercept of -0.20 on the line fitted to the data. [less ▲]

Cette enquête est une adaptation d’une étude équivalente réalisée, en 2002, au Québec. Le questionnaire comporte 20 questions réparties en 5 thèmes représentant les étapes de la recherche documentaire. Elle vise à connaître le niveau de compétences documentaires des étudiants qui arrivent dans l’enseignement supérieur, vérifier l’adéquation de celui-ci avec la perception qu’en ont les formateurs et identifier les lacunes afin de permettre d’améliorer les formations. 31 établissements d'enseignement universitaire et non universitaire ont accepté de participer à l’étude. Le questionnaire québécois adapté à la situation belge a été envoyé en septembre 2007 à un échantillon aléatoire de 4388 étudiants accédant pour la première fois à l'enseignement supérieur. Le taux de retour s’élève à 42,57%. Après analyse, il apparaît que comme au Québec, la moyenne des résultats est faible (7,67/20). Outre diverses variables sociologiques, certaines caractéristiques des étudiants sont en lien direct avec le niveau de performance, notamment la fréquentation d'une bibliothèque dans l'enseignement secondaire, le choix d'option dans le secondaire ou le choix actuel d’étude. A contrario, l'utilisation d'Internet ne semble pas favoriser la compétence informationnelle des étudiants. Ces observations confirment la nécessité de proposer des formations aux étudiants pour leur permettre d’atteindre les compétences requises par le métier d’étudiant. Les lacunes observées vont permettre d’adapter les formations existantes. L'étude doit se poursuivre pour évaluer l’impact réel des formations documentaires proposées. [less ▲]
