This article presents the results analyses of the archaeological and faunal assemblages from the Holocene strata at Trou Al'Wesse (Modave, Liège Province, Belgium). Two strata of human occupation are present in this sequence: the Early Neolithic in stratum 4.1 and the Late Mesolithic in stratum 4.2. The archaeological material includes lithics and ceramics. Faunal analysis of sample column K4 was done for paleoecological and taphonomic analysis of strata 4 and 12. [less ▲]

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 ▲]

The information that is necessary to perform the fire design of a structure made of a particular material, say a steel structure, is: a) The bases of design, stated in EN 1990. b) The mechanical actions, i.e. the forces, acting on the structure in the fire situation. Some information is found in EN 1991-1-2, but explicit reference is also made to EN 1991-1-1 that is therefore also necessary. c) The thermal actions, i.e. the fire and the heat flux induced in the elements by the fire. The information is in EN 1991-1-2. d) The rules for determining the temperatures in the structure during the course of the fire. They are given in the fire part of the relevant material eurocode, e.g. EN 1993-1-2 for a steel structure. e) The rules for determining the structural stability. They are given in the fire part of the relevant material Eurocode, e.g. EN 1993-1-2 for a steel structure, but reference is often made to the cold part of the same material Eurocode, EN 1993-1-1 for a steel structure. This layout is valid in general but some exceptions do exist: the structural stability of timber elements, for example, does not necessarily require the determination of the temperatures in the element and step d) may be omitted; the same holds if the fire resistance is determined from tabulated data, for concrete elements for example. The rest of this book is organised according to this layout, see Fig. 1-2: Chapter 2 deals with bases of design and mechanical loads. Chapter 3 deals with thermal attack from the fire. Chapter 4 deals with thermal analysis by simple calculation model. Chapter 5 deals with mechanical analysis by simple calculation model. Chapter 6 deals with the design of joints. Chapter 7 deals with thermal and mechanical analysis by the advanced calculation model. Chapter 8 gives four design examples showing how a complete and sometimes complex structure can be designed using the concept of element or substructure analysis. [less ▲]

This paper presents the resolution of a practical hydraulic engineering problem thanks to effective numerical tools. A sedimentation study of the lock of Hun (river Meuse, Belgium) is completed using solid transport models integrated in a finite volume free surface flows solver. The silting of the lock entrance is successfully modelled and various layout modifications of the site are tested to predict their effects and to see to what extent they could improve the actual situation. The analysis of the results shows that a regular dredging of the lock entrance is ineluctable. [less ▲]

In numerical simulations, it is always necessary to find an optimum between the simplicity of the model and a good representation of real phenomena. In the field of hydraulic flows simulations, the models using depth-averaged and moment equations are an interesting compromise between full 3D and simple depth-averaged models. This paper presents the use of a moment equation for suspended load transport. A simple but representative model for the sediment concentration profiles is developed. This original bi-linear concentration profile is compared to the traditional Rouse-profiles and shows a good correspondence despite its great simplicity. Advective and diffusive sediment fluxes are developed analytically and lead to a concise formulation, which is an asset for practical use. A differential equation for the sediment concentration moment is also fully developed, and a special attention is cast to the source term. The finite volume scheme has been chosen to implement the model, because it is particularly well suited for highly advective transport equations, it is conservative and it makes the choice of the upwinding easier. 1D simulations show the capacity of the model to reproduce laboratory experiments described in the literature.

The authors report the case of a patient aged 60-year-old who survived ulcerative colitis complicated by toxic megacolon and disseminated intravascular coagulation. This patient was not known for this ulcerative colitis and was first hospitalised for a suspicion of diverticulitis. The admission symptoms were fever, abdominal pain and bloody diarrhoea. The evolution was defavorable under antibiotics and sulfasalazine. The patient was readmitted 5 days after he left hospital, and the diagnosis of UC was based on colon biopsy made during the first hospitalisation. A treatment with methylprednisolone was started and the patient worsened day by day with apparition of toxic megacolon and disseminated intravascular coagulation. Subtotal colectomy was performed for degradation of general status and coagulation factors. Pathological findings confirmed ulcerative colitis with toxic megacolon. Cytomegalovirus inclusions were demonstrated on the colonic specimen and confirmed by PCR. In this report the authors discuss the etiology of toxic megacolon and disseminated intravascular coagulation in ulcerative colitis surinfected by cytomegalovirus. Mortality of these pathologies is high necessitating rapid diagnosis of cytomegalovirus infection by sigmoid biopsy. Management requires immunosupression interruption and ganciclovir therapy, or surgery in unsuccessful medical treatment. [less ▲]

The University of Liege Department of social Psychology for Groups and Organisations has been leading since 1999 an elaborate action research program on intense conflict situations in which people feel they are subjected to aggressions or bullying. This action research aims on the one hand to develop a better understanding of these issues and to find new directions for action. It includes interventions in organisations AND clinical work with people who felt they were subjected to bullying. In the course of our different interventions ( clinical as well as in organisations), we often felt that the concept of bullying was far too narrow, too restrictive to enable us to evoke all the situations we had to deal with even if people used this very word most of the time to refer to their situation and even if these situations included the usually accepted characteristics : hostile behaviour and prejudicial consequences for the persons aimed at ( Quine 1995). We have accordingly extracted from these experiments a few theoretical questions which inspire this article * Is this notion " bullying" appropriate for all the conflicts in which violent ways of behaving are perpetrated and in which people are subjected to important damages? * How should we consider situations in which the interfering parties are both violent and in which both parties suffer from it? * Can we try to define the concept of " hyper-conflict" to depict situations characterised by intense conflicts as far as ways of behaving, cognition as well as emotions are concerned. * * On the other hand, from an empirical point of view, two main explaining patterns seem to exist now in the field of victimisation at work ( Einarsen 1999). The first one focuses on the personality aspects of the people aimed at in these conflicts, the second deals with the part played by psychosocial factors. * On the strength of a bet according to which it might be fertile to insert results coming from meetings with victims giving pieces of information more related to the first pattern as well as from interventions in organisations ( where we expect the results to lean more on the side of the second pattern), we asked the following questions as research material: * * Can we identify recurring psychological and/or organisational patterns in these situations of intense conflicts? * Can we describe the dynamics of these patterns? * How can we describe the way the organisational and individual dimensions get interwoven to build up these dynamics without tracing the explanation to one dimension or to the other? This article deals more particularly with the standardisation of a conflictual pattern we encountered several times and which we named the Gavroche effect. This Gavroche effect concentrates around a psychosocial process of polarising- stigmatising that we will describe hereafter but before that we will sketch the aforementioned theoretical issues.
