The aim of this paper is to carry out a semantic analysis of the definitions proposed in the scientific literature and in legal texts to describe workplace victimization phenomena. Starting with the observation that there is a great diversity in how these phenomena are considered, the authors attempted to identify recurrences and differences between these various definitions. Three semantic poles were identified: the consequences for people and the environment, hostile behaviours, and the resources of the parties in which various components could be studied. Two questions promoting debate also emerged: the necessity for the author’s intention to talk about a victimization situation, and the place of conflict in harassment processes. Analysis of these definitions led to critical reflection about the problem of evaluation, diagnosis and the intervention relating to such situations. [less ▲]

Dans le domaine de la recherche sur le harcèlement moral au travail, un nouvel enjeu majeur est apparu au cours des dernières années : mieux comprendre la complexité des processus apparaissant à différents niveaux (individuel, interpersonnel, groupal, organisationnel) dans ces situations. Dans cette optique, nous utilisons un modèle d’analyse processuel, intégrateur et dynamique pour analyser le contenu de 100 entretiens menés avec des victimes de harcèlement moral. Les résultats montrent que les situations de harcèlement relèvent plus souvent d’une action négative de l’environnement social autour de la relation interpersonnelle entre harceleur et harcelé que de l’existence d’un processus victimatoire entre ces deux acteurs, qui apparaissent plutôt en conflit. En effet, la relation entre harceleur et harcelé ne relève que dans 22 cas sur 50 d’une dynamique victimatoire, alors qu’il existe une victimisation de l’environnement social (collègues et/ou organisation) dans 48 cas sur 50. Cinq profils de victimes sont également dégagés, mettant en lumière la diversité des configurations sociales du harcèlement. [less ▲]

Esthetic results in dentistry are determined by the harmony between the dental prostheses and the soft tissues. To reach an optimal result, each single step of the treatment has a great importance, from the smile analyses to the final restoration delivery. The goal of this lecture is to describe how to elaborate a treatment planning for single tooth replacement in the aesthetic zone. A decision tree for the surgical protocols will be proposed according to our clinical experience at the university of Liège and, the current scientific evidences. The overall objective is, from an initial clinical situation, to determine the appropriate treatment approach and timing. [less ▲]

We show that the data for the total cross section and for the real part of the elastic amplitude indicate the presence of a hard pomeron in pip and Kp elastic scattering at t = 0, compatible with that observed in deep inelastic scattering. We show that such a hard pomeron is also compatible with pp and pp data, provided one unitarises it at high energy. (C) 2004 Published by Elsevier B.V. [less ▲]

Spatially resolved images of the galactic supernova remnant G78.2+2.1 (gamma-Cygni) in hard X-ray energy bands from 25 keV to 120 keV are obtained with the IBIS-ISGRI imager aboard the International Gamma-Ray Astrophysics Laboratory INTEGRAL. The images are dominated by localized clumps of about ten arcmin in size. The flux of the most prominent North-Western (NW) clump is (1.7+/-0.4)x10(-11) erg cm(-2) s(-1) in the 25-40 keV band. The observed X-ray fluxes are in agreement with extrapolations of soft X-ray imaging observations of gamma-Cyg by ASCA GIS and spatially unresolved RXTE PCA data. The positions of the hard X-ray clumps correlate with bright patches of optical line emission, possibly indicating the presence of radiative shock waves in a shocked cloud. The observed spatial structure and spectra are consistent with model predictions of hard X-ray emission from nonthermal electrons accelerated by a radiative shock in a supernova interacting with an interstellar cloud, but the powerful stellar wind of the O9V star HD 193322 is a plausible candidate for the NW source as well.

Context: If relativistic particle acceleration takes place in colliding-wind binaries, hard X-rays and gamma-rays are expected through inverse Compton emission, but to date these have never been unambiguously detected. Aims: To detect this emission, observations of eta Carinae were performed with INTEGRAL, leveraging its high spatial resolution. Methods: Deep hard X-ray images of the region of eta Car were constructed in several energy bands. Results: The hard X-ray emission previously detected by BeppoSax around eta Car originates from at least 3 different point sources. The emission of eta Car itself can be isolated for the first time, and its spectrum unambiguously analyzed. The X-ray emission of eta Car in the 22-100 keV energy range is very hard (Gamma ~= 1 ± 0.4) and its luminosity is 7 × 10^33 erg s^-1. Conclusions: The observed emission is in agreement with the predictions of inverse Compton models, and corresponds to about 0.1% of the energy available in the wind collision. eta Car is expected to be detected in the GeV energy range.

Context. The colliding-wind binary η Carinae exhibits soft X-ray thermal emission that varies strongly around the periastron passage. It has been found to have non-thermal emission, thanks to its detection in hard X-rays using INTEGRAL and Suzaku, and also in γ-rays with AGILE and Fermi. <BR /> Aims: This paper attempts to definitively identify η Carinae as the source of the hard X-ray emission, to examine how changes in the 2-10 keV band influence changes in the hard X-ray band, and to understand more clearly the mechanisms producing the non-thermal emission using new INTEGRAL observations obtained close to periastron passage. <BR /> Methods: To strengthen the identification of η Carinae with the hard X-ray source, a long Chandra observation encompassing the INTEGRAL/ISGRI error circle was analysed, and all other soft X-ray sources (including the outer shell of η Carinae itself) were discarded as likely counter-parts. To expand the knowledge of the physical processes governing the X-ray lightcurve, new hard X-ray images of η Carinae were studied close to periastron, and compared to previous observations far from periastron. <BR /> Results: The INTEGRAL component, when represented by a power law (with a photon index Γ of 1.8), would produce more emission in the Chandra band than observed from any point source in the ISGRI error circle apart from η Carinae, as long as the hydrogen column density to the ISGRI source is lower than N[SUB]H[/SUB] ≲ 10[SUP]24[/SUP] cm[SUP]-2[/SUP]. Sources with such a high absorption are very rare, thus the hard X-ray emission is very likely to be associated with η Carinae. The eventual contribution of the outer shell to the non-thermal component also remains fairly limited. Close to periastron passage, a 3-σ detection is achieved for the hard X-ray emission of η Carinae, with a flux similar to the average value far from periastron. <BR /> Conclusions: Assuming a single absorption component for both the thermal and non-thermal sources, this 3-σ detection can be explained with a hydrogen column density that does not exceed N[SUB]H[/SUB] ≲ 6 × 10[SUP]23[/SUP] cm[SUP]-2[/SUP] without resorting to an intrinsic increase in the hard X-ray emission. The energy injected in hard X-rays (averaged over a month timescale) appears to be rather constant at least as close as a few stellar radii, well within the acceleration region of the wind. [less ▲]

Several members of the COROT Seismology Working Group (SWG) have performed several ``hare-and-hound'' exercises to prepare the data exploitation of the mission in the past few years. These exercises consist in reproducing a theoretical model on the basis of a light curve obtained from a frequency spectrum computed from an ``unknown'' theoretical model of a solar-like or a Delta Scuti star. Members of the BAG (Belgian Asteroseismology Group) have now shown that such an exercise in the mass range of Beta Cephei stars is extremely convincing, making these stars excellent targets for asteroseismology space missions.
