L’objectif de cette recherche consiste à étudier les processus économiques, politiques et sociaux ayant favorisé la diffusion de pratiques criminelles et mafieuses chez certains migrants d’origine italienne en Belgique. Nous émettons l’hypothèse que l’apparition de pratiques mafieuses ne se fait pas via l’exportation des activités criminelles sur une « base ethnique » d’un lieu à un autre, mais que ces pratiques se développent à la suite d'une adaptation aux contextes d’immigration où se vérifient toutes les conditions de transformation du parcours d’intégration de certains migrants en un parcours criminel ou mafieux. C’est pour cela que nous proposons un nouveau cadre théorique qui dépasse les interprétations habituelles sur les phénomènes mafieux dans les parcours d’immigration et qui se propose d’étudier le vaste et complexe système de relations dans lequel les forces criminelles s’enracinent. Pour ce faire, nous proposons de nous concentrer sur l’étude du secteur agroalimentaire et de la restauration dans lesquels la criminalité d’origine italienne a beaucoup investi durant les dernières décennies. Par ailleurs, nous proposons une analyse comparée à la société d’origine des migrants, le Sud de l’Italie, afin de comprendre les continuités et les ruptures dans les pratiques mafieuses entre les contextes d’origine des migrants et ceux présents dans les espaces d'immigration. Pour tester les hypothèses, cette recherche se base sur l’étude de la littérature scientifique, les données statistiques de la criminalité, les sources médiatiques, sur quelques dossiers figurant dans les archives judiciaires des tribunaux belges. Mais, la recherche est surtout basée sur une approche ethnographique qui repose sur des recueils biographiques, de récits familiaux et de l'observation participant en travaillant comme agent pour une entreprise d'import/export de produits italiens.

Ce papier s’inscrit dans un projet de recherche financé par le Fonds de la Recherche Scientifique – FNRS qui vise à mettre en rapport l’intérêt accru des savants pour l’Afrique à la fin du XVIIIe siècle et l’intensification de la compétition économique et militaire entre la France et la Grande-Bretagne. Ce projet ambitionne de démontrer comment une connaissance de plus en plus précise du terrain africain a influencé la façon dont les gouvernements des deux pays ont intégré l’expertise coloniale dans une politique scientifique complexe appropriée aux besoins spécifiques des deux états. L’originalité de cette étude consiste en l’approche comparative des « politiques scientifiques » coloniales successives de la France et de la Grande-Bretagne. Les récits de voyage ont joué évidemment un rôle important dans la collecte d’informations. Les expéditions ont été suivies de près par le public lettré, par les institutions scientifiques mais aussi par les décideurs politiques des deux côtés de la Manche. En plus de nouvelles données scientifiques, les récits contenaient également des informations d’importance économique et stratégique. Les fonctionnaires ont donc soumis les récits à l’analyse critique dès leur parution. On avait intérêt à faire traduire les récits composés par les concurrents. Ce papier mettra l’accent sur la traduction de récits de voyage français et britanniques, et sur leurs arrière-plans politiques. [less ▲]

In Belgium, female migrant Care workers are key elements for the demographic challenges the country faces. The ageing of the population and the insertion of native women in the labor market led to an increasing demand for their liable/affordable care-work. A key aspect that might help us to understand their careers toward their incorporation in Belgium are the circulations of care among and within their transnational family networks; which fluctuate over the life course and are subject to political, economic, cultural and social contexts of both sending and receiving societies. This study focuses precisely on the labor migration of Ecuadorian/Colombian care-workers in the global city of Brussels. Their labor migration could be seen as the result of their specific type of labor Care Work, the transnational care circulations among their families and the individual gender role changes that allow them to mobilize such resources. Considering this context, this research aims to understand how these women are actively mobilizing Transnational/familial Care Circulations in their careers towards their Incorporation in Belgium. In order to do so I will make use of a Care Circulation approach, which allows me to: Firstly, understand the individual characteristics and the transnational changes in Gender roles that either facilitates or constraint this mobilization of care. Secondly, link the individual level to the opportunities and constraints posed by the state institutions and migration regimes in this mobilization of care. Lastly, it allows me to take a look at the networks of co-nationals who over time sustain their settlement in Belgium and their transnational care-giving practices. It is through the combination of these past three aspects that this research contributes to a better understanding of the feminization of care labor migration in Belgium; by analyzing transnational family care circulation and showing the intersections between kinship and economic and political motivations in migratory moves, highlighting the role of family and the domestic sphere in sustaining diaspora ties and certain types of labor migration such as care-work. More over, it seeks to highlight these women’s agency within their transnational families and migratory projects, recognizing the heterogeneity in strategies and profiles even within the so-called “care sector”.

Economic evaluations of animal health surveillance systems are critical components of the assessment of their long-term sustainability and the improvement of their cost- effectiveness. Social costs and benefits of health information release through the surveillance systems are fundamental determinants of the acceptability and efficacy of surveillance and are often neglected in the evaluation process. This study presents the evaluation of social costs and benefits of Highly Pathogenic Avian Influenza (HPAI) surveillance in Vietnam. Three field studies were conducted in the South and North of the country. Data on animal health information flow networks and social costs and benefits were collected using participatory approaches. Non-monetary costs and benefits were quantified using a newly developed tool based on stated choice method and participatory techniques. The study showed that private actors incur many transaction costs in reporting the information. However social costs mainly arise from price drops due to information release on market which has strong influences on the decision to disclose sanitary information. This applies at all levels including farmers and veterinary authorities. Private actors of the poultry sector valued information on occurring disease outbreaks, which is perceived as a social benefit. However avian influenza information is scarcely disclosed in private networks as stakeholders fear its potential impact on markets. [less ▲]

Accurate evaluations of surveillance systems are keys in the guidance for critical health decisions and policy issues. However, current guidelines and frameworks used for evaluation are often providing a list of attributes (indicators) with no or few details about the methods used to measure these attributes. By reviewing the advantages and limits of existing methods and tools we highlighted the needs for innovative tools to assess specific attributes or to address specific evaluation questions. Indeed socio-economic and cultural context of surveillance are hardly ever considered within the evaluation process. Therefore we have identified a list of attributes that could be assessed completely or partially with the use of participatory approaches in order to improve the completeness of surveillance systems’ evaluation process. Moreover, these approaches should lead to improved recommendations and to a better acceptability by the stakeholders. [less ▲]

Methanol (CH3OH) is the second most abundant organic compound in the Earth's atmosphere after methane. In this work, we present the first long-term time series of methanol total, lower tropospheric and upper tropospheric-lower stratospheric partial columns derived from the analysis of high resolution Fourier transform infrared solar spectra recorded at the Jungfraujoch station (46.5° N, 3580 m a.s.l.). The retrieval of methanol is very challenging due to strong absorptions of ozone in the region of the selected υ8 band of CH3OH. Two wide spectral intervals have been defined and adjusted in order to maximize the information content. Methanol does not exhibit a significant trend over the 1995–2012 time period, but a strong seasonal modulation characterized by maximum values and variability in June–July, minimum columns in winter and a peak-to-peak amplitude of 130%. In situ measurements performed at the Jungfraujoch and ACE-FTS occultations give similar results for the methanol seasonal variation. The total and lower tropospheric columns are also compared with IMAGESv2 model simulations. There is no systematic bias between the observations and IMAGESv2 but the model underestimates the peak-to-peak amplitude of the seasonal modulations. [less ▲]

Consuming locusts and grasshoppers as food is not a new concept, because some people have been doing it for a long time and there are many references in the religious literature to support this. About 80 locust and grasshopper species are consumed worldwide, and the large majority of grasshopper species are edible. From the nutritional point of view they are an excellent source of proteins, lipids and other minor components like vitamins and minerals. They are an excellent source of amino acids and their lipids contain a large majority of unsaturated fatty acids. Environmentalists have supported human consumption of grasshoppers owing to the facts that they usually appear as pests. Using them as food could help reduce their population and result in limited application of harmful pesticides. Their production usually generates lesser amount of greenhouse gases & ammonia; a lower amount of water is required for their production in comparison to conventional proteins sources. Some species of grasshoppers usually feed on dead organic matter, this reduces the environmental load. In the developing world, catching of grasshoppers and selling them for human consumption has played a key role in improving the livelihood of women and underprivileged children. Eating grasshopper and locust is not a very common practice in temperate areas. However it is a very common practice in the tropical areas of world because of the higher density, bigger size of the insect and yearlong availability in such areas. To encourage their consumption in temperate areas, it is now necessary to perform accurate research regarding food safety (minor components, toxicity, allergens,…) but also to develop value added products to make it easier for people to adapt with entomophagy. Furthermore we have to develop methods for commercial production and organize awareness campaigns to explain about the nutritional and other benefits related to locust & grasshopper consumption as food to people.

Introduction La perception du temps a un retentissement majeur dans la vie quotidienne. Son déficit altère la capacité de l’enfant à intégrer le temps à la corporéité de son être et de ses activités. Seule le temps séquentiel est généralement évalué. Il n’existe pas de repères sémiologiques de la durée du temps, ni d’outils pour l’évaluer. Son évolution développementale est inconnue. Nous nous proposons d’évaluer la perception de la durée par des marqueurs sémiologiques en milieu écologique dans une population générale d’enfants et une population d’enfants avec une psychopathologie. Méthode Un questionnaire parental a été créé pour observer la perception du temps et appliqué dans 2 populations d'enfants de 2,5 à 12 ans : 827 enfants en population générale et 297 enfants consultant des Services de Santé Mentale (population transnosographique). Une régression logistique multinominale donne des courbes de percentiles (P5, P50, P95). Résultats Dans la population générale, la perception de la durée est progressivement acquise avec une pleine compétence à 9 ans. Le temps séquentiel est acquis à 4 ans. Dans la population consultant en SSM, la moyenne de la perception de la durée est retardée de 18 mois et demeure faible à 13 ans. Il n’y a pas de différences selon le sexe. Discussion La perception de la durée est une importante caractéristique développementale non prise en compte jusqu’à présent. Des enfants consultants en santé mentale ont un déficit de cette perception. Les marqueurs sémiologiques du questionnaire parental mis au point relèvent ces difficultés dans la vie quotidienne de l’enfant.

When choosing their sleeping sites, primates make adaptive trade‐offs between various biotic and abiotic constraints. In human‐modified environments, anthropic factors may play a role. We assessed the influence of ecological (predation), social (intergroup competition), and anthropic (proximity to human settlements) factors in sleeping site choice by long‐tailed macaques (Macaca fascicularis) occupying a habitat at the interface of natural forests and human‐modified zones in Bali Barat National Park, Indonesia. Over the course of 56 nights, we collected data relating to physical features of sleeping trees, patterns of the use of sleeping sites within the home range, pre‐sleep behavior, diurnal ranging patterns and availability of natural and human food. Overall, the macaques used 17 sleeping sites with 37 sleeping trees. When the monkeys slept in forest zones, they selected sleeping trees that had larger trunks but were not significantly taller than surrounding trees. Though the macaques rarely re‐used sleeping sites on consecutive nights, they frequently re‐used four sites over the study period. The group favored sleeping within the core area of its home range, despite the occurrence of frequent agonistic intergroup encounters there. Macaques preferentially selected sleeping trees located within or near human‐modified zones, especially when human food was abundant and natural food was scarce. These results partially support the hypothesis that long‐tailed macaques choose their sleeping sites to avoid predation; proximity to human settlements appears to be the primary factor influencing sleeping site choice in this primate species. Our results reflect the strong influence that anthropic factors have on primates, which subsist in increasingly human‐dominated landscapes. [less ▲]

The cross-sectional capacity is limited by material yielding on one hand and local buckling on the other hand. Most current metallic structural design codes use the concept of section classification for determining the section capacity of hot-rolled profiles. In this system, there exists a discontinuity between the classes 2 and 3 under pure bending load condition, while for the class 4, the effective width method (EWM) must be used to account for local buckling phenomenon. With the appearance of the more complex cross-sections, especially for thin-walled steel structures, the calculation using EWM becomes more and more intolerable and complicated. In order to overcome these difficulties when evaluating the cross-section strength, the alternative Direct Strength Method (DSM) approach, developed only for cold-formed thin-walled members, has gained importance over the last few years, and has been adopted by the North American and Australian standards for the design of cold-formed steel structural members recently. This thesis investigates the possibility to extend the DSM method to hot-rolled and welded structural steel members, and the objective is to derive a new formulation that would cover the whole field of section slenderness without section classification system used in Eurocode 3, using the same procedure for the DSM developed for cold-formed thin-walled steel structural members. Hot-rolled and welded H sections are mainly considered in this thesis. The DSM is premised on the assumption that the strength can be predicted from the yield strength to the elastic critical load ratio used in conjunction with a strength curve; i.e. the same concept than the one used in Eurocode 3, in terms of member buckling phenomenon. In the DSM approach applied for cold-formed thin-walled sections, local buckling and distortional buckling modes should be considered. For common hot-rolled or welded sections, only local buckling needs to be considered since distortional buckling does not occur for these sections. All available test results in literature are collected and evaluated with the current methods for calculating the cross-section resistance such as EWM, DSM, and the recent Continuous Strength Method (CSM). A short comparison is made and their domains of applicability are commented. A consistent approach has been adopted to develop numerical models for hot-rolled and welded sections subjected to compression and bending respectively. The FE model was built in FineLg and verified against test results of the “Semi-comp: Plastic member capacity of semi-compact steel sections - a more economic design” project, which was carried out earlier with the objective of improving the utilization of plasticity in rolled and welded sections with medium cross-section slenderness. Measured material and geometric properties, initial geometrical imperfections and residual stresses distributions have been highlighted. Once verified against the test results, the FE models have been used to carry out a parametrical study aimed at providing more FE results and highlighting the local buckling interaction between the webs and the flanges. All the experimental and FE numerical results constitute data base for the derivation of the new DSM curves. On the basis of Winter Formula for plate buckling and the generic DSM strength curve, different formulas are proposed for hot-rolled and welded H cross-sections under axial and bending load respectively. Also the statistical evaluation and safety study is conducted to obtain the safety factor γ_M, which is required for practical design. [less ▲]
