Nous assistons actuellement au peuplement des zones périurbaines de la planète par des centaines de millions d’individus. Cette évolution pose de redoutables problèmes et des difficultés inédites pour les politiques publiques. Si les effets de la périurbanisation sont relativement bien connus dans les pays du Nord, les analyses dédiées aux pays du Sud sont bien moins développées. L’ouvrage « Territoires périurbains : développement, enjeux et perspectives dans les pays du Sud » permet de lever un coin du voile sur cette problématique et sur les grands défis que la périurbanisation pose pour le Sud en général et pour l’Afrique centrale en particulier. L’ouvrage débute en cherchant à clarifier ce qu’il faut exactement entendre par « territoire périurbain ». À la suite de cette mise en contexte, il se poursuit par cinq parties organisées autour des problématiques des ressources naturelles, de la sécurité alimentaire, de la santé publique, des services publics et de l’aménagement des territoires. Pour chacune de ces problématiques, des chercheurs spécialisés issus de disciplines variées apportent des contributions qui, tout en soulignant l’ampleur des défis, permettent la mise en avant de solutions innovantes pour améliorer la gouvernance et le bien-être des populations. Cet ouvrage s’adresse d’abord aux chercheurs préoccupés par les défis du développement. En parallèle, par les pistes pour l’action publique qu’il esquisse, il ne manquera pas d’également intéresser les décideurs et les praticiens qui opèrent dans le contexte des territoires périurbains des pays du Sud.

Tree species influence biogeochemical cycling through element deposition (throughfall, litterfall), root decomposition and exudates, and through their influence on the microbial activities in the soil. Yet, the effect of mixing tree species on soil functioning is unclear, in particular concerning the microbial diversity and activity in soils. Here we synthesize results from the Exploratory Platform of the FunDivEUROPE project (http://www.fundiveurope.eu/). This network of 209 comparative plots covering tree diversity levels of 1 to 5 species was established in existing mature forests in 6 European regions. These six focal regions represent a gradient of major European forest types from boreal to Mediterranean forests. The aims of this study were to determine the soil microbial biomass and metabolic diversity of soil bacteria for these 6 European forest regions, presenting each a tree species richness gradient and to analyse the impact of tree species richness and the role of other controlling factors. We analysed the relation between tree species diversity, the proportion of coniferous tree species and soil factors (pH, soil organic carbon, water soluble carbon and nitrogen) and the carbon substrate utilisation pattern of soil bacteria (BIOLOG Ecoplate), soil microbial biomass (fumigation-extraction), hot water carbon and nitrogen in the forest floor and the upper mineral soil horizon (linear mixed models, GLM for multivariate abundance data, discriminant correspondence analysis). Mean values of microbial biomass carbon ranged from 3264 (Italy) to 8717 (Finland) mg kg-1 in the forest floor and from 465 (Italy) to 3748 (Finland) mg kg-1 in the mineral soil. Statistical models predicted microbial biomass to increase in both soil layers by 7-8% with each step increase in tree diversity. Increased proportion of conifers was linked to a decrease in the number of carbon substrates used by soil bacteria. The types of carbon sources used were dependent on region, proportion of conifers, soil pH and water-soluble carbon and nitrogen. [less ▲]

En Belgique, la réforme de la santé mentale a récemment été élargie aux populations internées dans le cadre de la loi dite « de défense sociale ». Construite sur un modèle communautaire du soin, elle propose une approche globale et intégrée de tous les acteurs, services et secteurs pertinents. Tout en développant les principaux axes de la réforme, l’article questionne la mise en œuvre de ce modèle dans le contexte hybride de l’internement entre mesure de protection et nécessité de soins.

The main goal of this paper is to provide an integrated overview of the literature devoted to identifying the causes of the British industrial revolution. Why did the industrial revolution, a fascinating and multifaceted event which brought about modern economic growth, occur in eighteenth-century Britain? This question has animated a lot of discussions among scholars and is still nowadays heatedly debated in the literature. This debate is reflected in the large spectrum of theories which aim at explaining the true origins of the British industrialization. The paper first sheds light on a rising debate concerning the evolution of British incomes per capita before the British industrial revolution and the “Great Divergence”. The paper then investigates the proposed causes of the British industrialization, aggregating them into seven broad categories, i.e. (1) geography and natural resources, (2) demography, (3) agricultural progress, (4) demand-side factors, (5) trade and empire, (6) institutional and political factors, (7) science, technology, and human capital.

Foreign language classroom assessment practices are a mystery, at least in Belgium. The present case study aims at shedding light on Belgian foreign languages teachers’ assessment practices in secondary education. I interviewed seven teachers to know what they assessed and how often they assessed it. I also analyzed the legal provisions that teachers have to respect when they assess. The results show that teachers assess four communicative skills—listening, reading, writing, and speaking—as legally required, but also reveal that they frequently assess vocabulary and grammar, sometimes in ways that are not permitted. Furthermore, they spend a considerable amount of time assessing those skills without even being aware of it. Since these assessments only aim at verifying that the students master the skills, it may be worth investigating whether some assessments are not redundant so as to devote that time to a more productive task.

Nombreux sont les sylviculteurs qui souhaitent régénérer naturellement la chênaie mais le processus demande une gestion pointue, permettant de contourner les obstacles. Une régénération naturelle du chêne sessile a été mise en place dès 1989 dans un compartiment de 16 ha situé sur le cantonnement DNF de La Roche-en-Ardenne (Belgique). Le peuplement initial était un médiocre taillis sous futaie de chêne et de hêtre à sous-étage de charme. Par ses observations et ses actions précises, le gestionnaire a réussi à installer les semis de chêne, à en soustraire suffisamment de la dent du gibier, bien présent, pour constituer un peuplement de qualité. Les enseignements de l'expérience sont multiples. Quelques points essentiels sont exposés : dosage fin de la lumière pour favoriser le développement des semis de chêne en maîtrisant le hêtre et la végétation adventice, observation de la réaction des semis comme indicateur du moment de l'intervention, exploitation adaptée, dégagement et/ou dépressage dans le semis, pression du gibier, etc. Actuellement, le chêne est régénéré sur plus de 12 ha. Le coût total est estimé entre 800 et 1000 €/ha. [less ▲]

When a district heating network is fed by natural gas boilers (or biomass boilers), the selection of the network temperature level has a slight influence on the boiler efficiency which means that producing at low temperature allows only to decrease the heat losses through the network. However when a cogeneration plant based on a Rankine cycle is used, lowering the network temperature not only decreases the heat losses but also increase the electrical efficiency while decreasing the thermal efficiency. This aspect is very often overlooked when the quality of a cogeneration plant is assessed by the cogeneration efficiency namely the sum of the electrical and thermal efficiency which is misleading for decision makers. In this contribution, an existing cogeneration plant connected to a district heating network installed on the University Campus in Liège (Belgium) is used as an application test case. Based on actual operational and economic data, a detailed economic evaluation is carried out which is supported by a calibrated simulation model of the whole installation in order to study the influence of the network temperature level. As a second step, the simulation model is used again to perform a detailed exergetic analysis intended to give physical insights to the economical study. This results in a broader discussion on the several methods to assess the quality of cogeneration plants and the opportunity to develop such a technology together with district heating networks.

This paper deals with the problem of the origin of the verbal endings in Middle Persian and Parthian and seeks to show a feasible history of their evolution from proto-Iranian onwards. Starting from the assumption that the present indicative of Western Middle Iranian emerged from two old tenses, viz. present and imperfect, my aim is showing how both tenses converged in a single paradigm and how traces of both appear here and there.

Gut content examination and trophic markers (fatty acids, stables isotopes of C and N) were combined to delineate the diet of the dominant species of amphipods from Mediterranean Posidonia oceanica seagrass meadows and to highlight trophic diversity among this community. Our results indicate that, although all dominant species heavily relied on macroalgal epiphytes, considerable interspecific dietary differences existed. Carbon stable isotope ratios notably showed that some of the amphipod species favored grazing on epiphytes from leaves or litter fragments (Apherusa chiereghinii, Aora spinicornis, Gammarus aequicauda), while others like Dexamine spiniventris preferred epiphytes from rhizomes. The remaining amphipods (Caprella acanthifera, Ampithoe helleri and Gammarella fucicola) readily consumed both groups. In addition, SIAR modeling suggested that most species had a mixed diet, and relied on several food items. Fatty acid analysis and gut contents revealed that contribution of microepiphytic diatoms and of benthic and suspended particulate organic matter to the diet of amphipods were anecdotal. None of the examined species seemed to graze on their seagrass host (low 18:2(n-6) and 18:3(n-3) fatty acids contents), but G. aequicauda partly relied on seagrass leaf detritus, as demonstrated by the lesser 13C-depletion of their tissues. Overall, our findings suggest that amphipods, because of their importance in transfers of organic matter from primary producers and detritus to higher rank consumers, are key-items in P. oceanica associated food webs.
