This paper reports the representations and practices evolution of two CoPs’ members of the domain of education who used ICT tools and services supporting collaborative edition and documents production. These artefacts related to multimedia authoring, knowledge management and mediation are based on the respect of standards allowing data accessibility, reusability and interoperability.They have been developed within the framework of the European project PALETTE through a participatory design process in which these CoPs were involved. <br />The evolution of the CoPs’ members’ representations and practices was observed through answers to a questionnaire (before and after the activities), the individual logbooks weekly handled by the participants, interviews and their productions. <br />First, we observed that the use of several tools or services allows the members to become more <br />competent in the domain of the ICT in terms of practices and technological literacy. They discover more transverse functions through the tools and feel more comfortable when using new interfaces. <br />This also decreases fears of certain members who had negative representations regarding ICT. <br />Then, the scenarios concretely offered to the CoPs’ members to live collaborative activities supported by ICT artefacts. They could exchange ideas, resources and knowledge. These experiments enabled them to refine their representations about collaborative learning and to get reference tools to support their future activities. They declared the use of these artefacts allowed the emergence of a CoP but also the development of the feeling of belonging to a CoP. The tasks realization during the trials created some common interests between the members. For many of them it was their first experiment in collaborative edition. They learned favourable modes and codes to produce and exchange when carrying on this kind of task. They also perceived the importance of the role of a CoP animator. <br />As for the production of documents, the discovery of several new tools allowed the CoPs’ members to compare them with different editors and examine their advantages and disadvantages. Even if the tools were not still or sufficiently accepted and adopted by the members, this comparison allowed a certain awareness of the importance of standards, exchangeable documents and durability of data.

A new model for multivariate non-normal longitudinal data is proposed. In a first step, each longitudinal series of data corresponding to a given response is modelled separately using a copula to relate the marginal distributions of the response at each time of observation. In a second step, at each observation time, the conditional (on the past) distributions of each response are related using another copula describing the relationship between the corresponding variables. Note that there is no need to consider the same family of distributions for these response variables. The technique is illustrated in a dose titration safety study on a new antidepressant. The haemodynamic effect on diastolic blood pressure, systolic blood pressure and heart rate is studied. These three responses are measured repeatedly over time on ten healthy volunteers during the dose escalation. The available covariates are sex and the concentration of drug in the plasma at time of measurement. [less ▲]

The medial preoptic nucleus (POM) of the quail preoptic area is sexually dimorphic and testosterone sensitive. Stereotaxic implantation of needles filled with crystalline testosterone demonstrated that the POM is a critical site of steroid action in the control of copulatory behavior. Only implants located in the POM reliably restored the behavior in castrated birds. Implants around the nucleus weakly activated the behavior; those which were distant by more than 200 microns were totally inactive. Electrolytic lesions confirmed the role of the POM in the control of copulatory behavior. The percentage of the POM which was lesioned was highly correlated to the behavioral deficit while the absolute size of the lesion was not. Electrolytic lesions in or around POM also significantly decreased the volume of the nucleus suggesting that the afferents and efferents of the nucleus are required for its full development. The total volume of the POM was correlated with the sexual behavior of the birds. The morphological changes in POM observed following exposure to testosterone probably represent the signature of the behavioral effects of the steroid. The sexually dimorphic testosterone-sensitive POM is therefore an excellent animal model to study the brain-steroid interactions which mediate the activation of male reproductive behavior. [less ▲]

Context. Since 1998, a planet-search program around main sequence stars within 50 pc in the southern hemisphere has been carried out with the CORALIE echelle spectrograph at La Silla Observatory. Aims: With an observing time span of more than 14 years, the CORALIE survey is now able to unveil Jovian planets on Jupiter's period domain. This growing period-interval coverage is important for building formation and migration models since observational constraints are still weak for periods beyond the ice line. Methods: Long-term precise Doppler measurements with the CORALIE echelle spectrograph, together with a few additional observations made with the HARPS spectrograph on the ESO 3.6 m telescope, reveal radial velocity signatures of massive planetary companions on long-period orbits. Results: In this paper we present seven new planets orbiting HD 27631, HD 98649, HD 106515A, HD 166724, HD 196067, HD 219077, and HD 220689, together with the CORALIE orbital parameters for three already known planets around HD 10647, HD 30562, and HD 86226. The period range of the new planetary companions goes from 2200 to 5500 days and covers a mass domain between 1 and 10.5 MJup. Surprisingly, five of them present very high eccentricities above e > 0.57. A pumping scenario by Kozai mechanism may be invoked for HD 106515Ab and HD 196067b, which are both orbiting stars in multiple systems. Since the presence of a third massive body cannot be inferred from the data of HD 98649b, HD 166724b, and HD 219077b, the origin of the eccentricity of these systems remains unknown. Except for HD 10647b, no constraint on the upper mass of the planets is provided by Hipparcos astrometric data. Finally, the hosts of these long period planets show no metallicity excess. [less ▲]

We report the detection of a double planetary system around HD 140718 as well as the discovery of two long period and massive planets orbiting HD 171238 and HD 204313. Those discoveries were made with the CORALIE Echelle spectrograph mounted on the 1.2-m Euler Swiss telescope located at La Silla Observatory, Chile. The planetary system orbiting the nearby G9 dwarf HD 147018 is composed of an eccentric inner planet (e = 0.47) with twice the mass of Jupiter (2.1 MJup) and with an orbital period of 44.24 days. The outer planet is even more massive (6.6 MJup) with a slightly eccentric orbit (e = 0.13) and a period of 1008 days. The planet orbiting HD 171238 has a minimum mass of 2.6 MJup, a period of 1523 days and an eccentricity of 0.40. It orbits a G8 dwarfs at 2.5 AU. The last planet, <ASTROBJ>HD 204313</ASTROBJ> b, is a 4.0 M[SUB]Jup[/SUB]-planet with a period of 5.3 years and has a low eccentricity (e = 0.13). It orbits a G5 dwarfs at 3.1 AU. The three parent stars are metal rich, which further strengthens the case that massive planets tend to form around metal rich stars. [less ▲]
