[more ▼]Purpose – Fair trade organisations (FTOs) have been taken quite early as examples of Social Enterprises (SE) and have contributed to the shaping of the SE concept. The purpose of this paper is to examine more deeply the link between FTOs and SE, both at a conceptual and at an empirical level. Design/methodology/approach – First, different theoretical frameworks of SE are introduced and confront FT to each of these frameworks. The second step is an empirical study of FTOs across four European countries to illustrate and deepen the links between FT and SE, focusing on the goals and the governance structures of FTOs. Findings – All the FTOs combine in some way economic, social and sometimes also political goals. FTOs are thus coherent to the “hybrid goals” nature of SEs. FTOs' governance is also quite specific and often innovative in terms of organisational architecture and stakeholders' involvement. Some FTOs are closer to the European – participatory – approach while others are closer to US – individual – approaches. Finally, the governance structures of FTOs seem to reflect quite well their goal mix. Research limitations/implications – This paper provides a more solid basis for the often implicit link between FT and SE. Future researches could use this work to explore specific topics of the SE literature in the context of FT (e.g. stakeholders' involvement). The FT example could also be used to examine further the shifting boundaries of the SE reality. Originality/value – The originality of this paper is to apply the SE concept to a specific field and to show how, within this field, there is at the same time a diversity of organisations, reflecting the diversity of SE approaches; and a range of specific features (especially in terms of goal mix and governance) distinguishing SEs from other types of organisations.

[more ▼]In the Kivu region located in east of the Democratic Republic of the Congo, malnutrition and malaria is a major cause of morbidity and mortality. The relationship between malaria and malnutrition is unclear and has never been studied in the Kivu region. This report presents an analysis of data from 5695 children aged 0 to 5 years, admitted to the paediatric ward of Lwiro hospital between November 1992 and February 2004. The weight/age (W/A) index and weight/height (W/H) index expressed with standard deviation in relation to the reference median were calculated (Z score). The association between protein-energetic malnutrition and malaria infection and nutritional indicators was measured based on prevalence ratios determined by univariate analysis and adjusted Odds Ratio (OR) derived using a multivariate model. The prevalence of malaria at the time of admission was 35.8 % (n=5695). The W/A and W/H indexes and serum albumin level were correlated with malaria-related morbidity. Logistic regression showed that high malaria OR was associated with both anthropometric nutritional indicators [WHZ > -2: OR (CI 95 %) 1.7 (1.4-2.2)] [WAZ > -2: OR (CI 95 %) 1.3 (1.1-1.6)] and biological nutritional indicators [serum albumin > or = 23 g/L: OR (CI 95 %) 1.6 (1.2-2.1)]. Our findings indicate that malnourished children at admission have a lower risk of malaria infection.

Ovsienko, Projectively equivariant quantization and symbol calculus: Noncommutative hypergeometric functions, Lett. Math. Phys. 57 (1) (2001) 61–67], the authors showed the existence and the uniqueness of a sl(m+1,R)-equivariant quantization in non-critical situations. The curved generalization of the sl(m+1,R)-equivariant quantization is the natural and projectively equivariant quantization. In [M. Bordemann, Sur l’existence d’une prescription d’ordre naturelle projectivement invariante (submitted for publication). math.DG/0208171] and [Pierre Mathonet, Fabian Radoux, Natural and projectively equivariant quantizations by means of Cartan connections, Lett. Math. Phys. 72 (3) (2005) 183–196], the existence of such a quantization was proved in two different ways. In this paper, we show that this quantization is not unique.

[more ▼]We report on the cDNA cloning and characterization of a novel short-chain isoprenyl diphosphate synthase from the aphid Myzus persicae. Of the three IPPS cDNAs we cloned, two yielded prenyltransferase activity following expression in Escherichia coli; these cDNAs encode identical proteins except for the presence, in one of them, of an N-terminal mitochondrial targeting peptide. Although the aphid enzyme was predicted to be a farnesyl diphosphate synthase by BLASTP analysis, rMpIPPS, when isopentenyl diphosphate and dimethylallyl diphosphate are supplied as substrates, typically generated geranyl diphosphate (C10) as its main product, along with significant quantities of farnesyl diphosphate (C15). Analysis of an MpIPPS homology model pointed to substitutions that could confer GPP/FPP synthase activity to the aphid enzyme.

[more ▼]Dans un monde de plus en plus interdépendant, il nous arrive de nous sentir manipulés par les acteurs dominants que sont les institutions économiques internationales, les entreprises mondialisées, les grands médias ou les principaux responsables politiques. Pour autant, l’homme ordinaire d’aujourd’hui n’est-il vraiment qu’une marionnette comme le prétend toute une partie de la critique de gauche ? Ne sommes-nous pas davantage acteurs qu’on nous le prétend et n’avons-nous pas mieux à faire que de voir partout des manipulations et des « agendas cachés » ? C’est à cette réflexion que nous invitent les auteurs.

[more ▼]Toll-like receptors (TLRs) as well as the receptors for tumor necrosis factor (TNF-R) and interleukin-1 (IL-1R) play an important role in innate immunity by regulating the activity of distinct transcription factors such as nuclear factor-kappaB (NF-kappaB). TLR, IL-1R and TNF-R signaling to NF-kappaB converge on a common IkappaB kinase complex that phosphorylates the NF-kappaB inhibitory protein IkappaBalpha. However, upstream signaling components are in large part receptor-specific. Nevertheless, the principles of signaling are similar, involving the recruitment of specific adaptor proteins and the activation of kinase cascades in which protein-protein interactions are controlled by poly-ubiquitination. In this review, we will discuss our current knowledge of NF-kappaB signaling in response to TLR-4, TNF-R and IL-1R stimulation, with a special focus on the similarities and dissimilarities among these pathways.

[more ▼]This contribution aims to show a multidisciplinary method to understand and formalize design process, from a cognitive point of view, in the particular case of human errors in architectural preliminary design process. We first emphasize the importance of error detection and recovery in the sketching phase in architecture. After the description of our methodology, we explain the general theory and model on human error, the short study we made and our proposition of a model on hu- man error in architectural design. We finally conclude by giving some first re- quirements from this model in order to improve to the development of sketch- based CAD tools.

[more ▼]Using standard group theoretical techniques we construct the exact wave function of the $[{\bf 70},1^-]$ multiplet in the orbital, spin and flavor space. This symmetric wave function is compared to that customarily used in the $1/N_c$ expansion, which is asymmetric. The comparison is made by analyzing the matrix elements of various operators entering the mass formula. These matrix elements are calculated by the help of isoscalar factors of the permutation group, specially derived for this purpose as a function of $N_c$. We also compare two distinct methods used in the study of the $[{\bf 70},1^-]$ multiplet. In the first method the generators are divided into two parts, one part acting on a subsystem of $N_c-1$ quarks called core and another on the separated quark. In the second method the system is treated as a whole. We show that the latter is simpler and allows to clearly reveal the physically important operators in the mass formula.

[more ▼]Analysis of passive microwave brightness temperatures from the space-borne Special Sensor Microwave Imager (SSM/I) documents a record surface snowmelt over high elevations (above 2000 m) of the Greenland ice sheet during summer of 2007. To interpret this record, results from the SSM/I are examined in conjunction with fields from the National Centers for Environmental Prediction/National Center for Atmospheric Research reanalysis and output from a regional climate model. The record surface melt reflects unusually warm conditions, seen in positive summertime anomalies of surface air temperatures, downwelling longwave radiation, 1000–500 hPa atmospheric thickness, and the net surface energy flux, linked in turn to southerly airflow over the ice sheet. Low snow accumulation may have contributed to the record through promoting anomalously low surface albedo.
