Whereas it is obvious that the failure process can vary from one firm to another (Argenti, 1976; D'Aveni, 1989; Laitinen, 1991), to date, few researchers have worked on the detection of several explanatory failure patterns. In addition, none of the reviewed research really focuses on small firms while their failure is important and particular (Julien, 2005). Considering these observations and on the basis of two complementary statistical analyses (Thiétart, 2003), this article identifies, among a sample of 208 small Belgian distressed firms, a taxonomy of five explanatory business failure patterns, i.e. five homogeneous groups of small firms on the basis of the reasons for their failure. As the detection of the fundamental explanatory failure factors is the basis of failure prevention (Argenti, 1976), the identification of these patterns is of crucial importance for a better understanding and for a better prevention of this phenomenon [less ▲]

We studied the identification of key habitat parameters for two specialist woodpecker species (middle spotted woodpecker Dendrocopos medius and lesser spotted woodpecker D. minor) associated with mature broadleaved forests ecosystems in Europe, and the modelling of their specific requirements with a view to assist forest managers. The study was conducted in four beech and oak-dominated forests (Haut-Fays, Halma, Gembes and Croix-Scaille) located in the Ardennes Region of Southern Belgium. The study sites covered a total area of ca. 20 km². A census of woodpecker occurrence (presenceabsence) was implemented from 2000 to 2003 within 255 1-ha plots. Habitat variables describing stand age, tree density, snag density, stand composition and vertical vegetation structure were also sampled at the same plots to develop both logistic and autologistic regression models describing habitat use.Middle spotted woodpecker (MSW) uses the oak-rich locations (mean basal area of 15.6 m²/ha), with selection of areas with the largest, oldest oak trees (mean circumference > 150 cm), and with a high diversity of tree species in the overstory. Similarly, the lesser spotted woodpecker (LSW) was detected in areas presenting the highest percentage cover of oak trees but with a selection of younger stands, with a high density of snags and dead wood (mean of 9 m³/ha). The integration of an autocorrelation term improved model performance for the LSW but not for MSW. Our results highlight the importance of a high disponibility of oak trees for these two sympatric species. The climax forest in northwest Europe is beech so that public and private owners must develop appropriate forest management plans to prevent the conversion of oak to beech forests. In particular, forest managers can promote an active oakregeneration management to obtain a balanced representation of age classes. They must also aim to maintain/increase the volume of dead wood resources by reserving all trees produced by storms or any other cause of natural mortality. [less ▲]

The Katanga copper belt, where natural outcrops of copper-rich rocks are colonised by highly original plant communities, has been recognised as a hotspot for metallophyte species. The flora comprises more than 600 species from which 30 are endemics. These plants represent a valuable phytogenetic resource for revegetation and restoration programs, for the phytostabilisation and for the remediation of heavy metal pollutions. However, the flora of metalliferous soils is threatened by mining activities in Katanga. Actions aiming at preserving these species are therefore urgent. Since 2007, a unique conservation project has been launched by scientists supported by a mining company. The aim is to elaborate a program that allows biodiversity conservation while being compatible with mining activities. The project combines in-situ and ex-situ conservation strategies involving ecosystem reconstruction, species translocations, protected areas designation and the development of seed banks in Belgium and in Katanga.

La population nicheuse de balbuzards pêcheurs en région Centre, principalement établie en forêt d'Orléans et en Sologne, a fait l'objet d'une prémière étude sur le choix des proies et la stratégie alimentaire. L'analyse a été menée sur un échantillon d'une quinzaine de couples. Les premiers résultats montrent que les rapaces consomment une large gamme de poissons, évaluéenà plus de 20 espèces. Quels que soient la méthode utilisée et le nid étudié, ce sont les cyprinidés qui constituent la grande majorité des proies. En période d'étiage, les espèces de poisson de fond viennent également enrichir le régime alimentaire en raison de la faible profondeur de l'eau. [less ▲]

Cervical cancer, the second most frequent gynaecological malignancy in the world, is caused by infection with high-risk human papillomaviruses (HPV). HPV16 and/or 18 are detected in more than 70% of these tumours. Prophylactic HPV-L1 virus like particle (VLP) vaccines are highly efficient to protect against HPV16 and HPV18 infection, but not against established infection. In this context, we study the effect of HPV-VLP on natural killer cells (NK) and on the crosstalk between NK and Dendritic Cells (DC). In order to know if HPV-VLP are able to enter in NK cells, we used fluorescent HPV-VLP with flow cytometry and confocal microscopy. HPV-VLP were internalised more rapidly in NK cells than in DC. They were already detected inside NK cells after 10 min of contact at 37°C. We also observed in CD107 assays, that HPV-VLP induce degranulation of NK cytotoxic granules. Previous works have shown that HPV-VLP were able to activate DC. We confirmed these results and observed an increase of CD69 cell surface expression and IFN-γ production by NK cells in the presence of DC activated by VLP. Interestingly, NK cells seemed to further activate DC in the presence of VLP as shown by an up-regulation of HLA-DR and CD86 on DC. Moreover, NK cells in the presence of HPV-VLP induced the production of IL12p70, but not the immunosuppressive cytokine IL10. Our results suggest that NK cells could play a role in the activation of DC induced by HPV-VLP during the vaccination against cervical cancer. Supported by the Belgian FNRS-Télévie [less ▲]

The high productivity of coral reef ecosystems is largely attributed to the mutualistic symbiosis between reef-building corals and their intracellular dinoflagellate in the genus Symbiodinium commonly referred to as zooxanthellae. These photosynthetic algae translocate a majority of their photosynthetically fixed carbon to the host and contribute greatly to their metabolic needs (Muscatine, 1990) and the calcification process (Gattuso, 1999). In the natural environment the holobiont have to cope with significant daily variations in light intensities that sometimes exceed Symbiodinium photosynthetic capacity. Fortunately, photosynthetic organisms possess regulatory features that help to ensure that high light intensities can be endured without the accumulation of photodamage. Thus, the regulation of photosynthesis can be viewed as a dynamic balance between photosynthetic efficiency (photochemical quenching) and photoprotection processes (i.e. non-photochemical quenching). Among them, the role of O2 as an alternative electron acceptor within the chloroplast could play a critical role (Ort & Baker, 2002). Under particular environmental conditions when sinks for photosynthetic electrons are scarce, the direct reduction of oxygen by the PSI could sustain significant levels of photosynthetic electron flux by initiating the ΔpH formation and of NPQ, regulating the ratio of ATP/NADPH to match the requirements of carbon reduction. However, this process leads to the formation of reactive oxygen species that are rapidly detoxified by superoxide dismutase and ascorbate peroxidase. An additional electron flux associated with this oxygen pathway is directed to the reduction of monodehydroascorbate (MDA), which is generated as a result of peroxide reduction by ascorbate (Asada, 2000). The present study aimed to highlight the existence of alternative photosynthetic electron pathways and more especially the Mehler ascorbate peroxidase pathway in different clades of Symbiodinium, cultivated at low and high light intensities. -Muscatine L (1990) The role of symbiotic algae in carbon and energy flux in reef corals.

In this talk, I will discuss some new properties of S-automatic sets. First I will show that a multidimensional set is S-automatic for all abstract numeration systems S if and only if it is 1-automatic. This result is surprising in the following sense: the class of multidimensional 1-automatic sets is a strict subclass of that of semi-linear sets. Hence, this result is not a generalization of the well-known result in integer base numeration systems: a multidimensional set is b-automatic for all integer bases b ≥ 1 if and only if it is semi-linear. Second I will describe the possible behaviors of the nth -term of an S-automatic set, depending on the growth function (i.e., the number of words of length n) of the numeration language. [less ▲]
