Antwerp is the largest city in Flanders and its population comprises around 13% foreigners. Yet a quarter of the inhabitants have a migration background and they represent 30% of the working population. Until recently, the diversity policy adopted by the city focused on specific target groups – people with a migration background was one of them. It was a categorial diversity policy. And specific departments were in charge to stimulate and support the policy through specific measures and actions with respect to each specific target group. The Integration Service and in particular the IS diversity consultants developed intensive contacts with some other services such as the Urban Poverty Department. The main challenges remain the language barriers and the recruitment procedures of the city. [less ▲]

The city of Valencia has a population of 807,396 inhabitants and is the centre of an extensive metropolitan area which brings the number to a million and a half people. This total represents 18% of the population of the Valencian region and makes Valencia, in terms of population, the third largest city in Spain after Madrid and Barcelona. It is also the third largest city in terms of registered immigrants. Foreign nationals – just as Spaniards – have to register in the municipal census. The city population increased throughout the 20th century and was stable during the 1990s. At the beginning of the 21st century, a strong migratory inflow has led to a new dynamic increase in the population. [less ▲]

The local dairy commodity, from farm to retail point, is informal and often escapes safety surveillance and results in high contamination of local milk by pathogens. The objective of this study was to determine the biodiversity of Bifidobacterium species in the informal dairy production chain in Abidjan and evaluate their potential antibacterial activity against pathogens. Bifidobacterium species were identified after sequencing of hsp60 genes. Results showed that Bifidobacterium were present in 9% of samples. Milkers' hands (14%) and cows’s udders (14%) were the most contaminated with Bifidobacterium. These isolates belong to five different species. Most Bifidobacterium isolated are Bifidobacterium minimum (53%) and Bifidobacterium pseudolongum subsp. Globosum (24.4%). The other strains are composed of one strain of Bifidobacterium thermophilum, Bifidobacterium thermacidophilum subsp. suis and Bifidobacterium magnum. The isolated Bifidobacterium species have antibacterial activities that are not related to bacteriocins production, but to organic acids production (65%), which exert in vitro inhibitory action against Listeria monocytogenes, Salmonella hadar and Salmonella typhimurium, Staphylococcus aureus, Escherichia coli O27 and Escherichia coli O157H7. However, ensuring milk safety along the local milk production chain requires implementation of good hygiene practices together with adapted technology, such as fermentation. [less ▲]

beta-Lactamase production is responsible for the appearance of a large number of pathogenic bacterial strains exhibiting a high degree of resistance to beta-lactam antibiotics. A large number of enzymes have been described with very diverse primary structures and catalytic profiles. Nevertheless, all known three-dimensional structures of active-site serine beta-lactamases exhibit a high degree of similarity with apparently equivalent chemical functionalities in the same strategic positions. These groups might not, however, play identical roles in the various classes of enzymes. Structural data have also been recently obtained for the zinc metallo-beta-lactamases, but the detailed catalytic mechanisms might also differ widely, depending on the enzyme studied. Similarly, the induction of the synthesis of beta-lactamases is now better understood, but many questions remain to be answered. [less ▲]

Although warming and plant diversity losses have important effects on aboveground ecosystem functioning, their belowground effects remain largely unknown. We studied the impact of a 3 °C warming and of three plant functional groups (forbs, grasses, legumes) on ammonia-oxidizing bacteria (AOB) diversity (polymerase chain reaction-denaturing gradient gel electrophoresis, PCR-DGGE) and their function (potential nitrification) in artificial grasslands. Warming did not influence AOB diversity and function. Sequencing of 16S rRNA gene fragments retrieved from DGGE gel revealed that they were all related to Nitrosospira-like sequences. Clustering analysis of DGGE profiles resulted in two nodes, separating AOB community structure under legumes from all other samples. Decreased AOB richness (number of DGGE bands) and concurrent increased potential nitrification were also observed under legumes. We hypothesized that ammonium availability was the driving force regulating the link between aboveground and belowground communities, as well as the AOB diversity and function link. The results document that the physiology of AOB might be an important regulator of AOB community structure and function under plant functional groups. This study highlights the major role of the microbial community composition in soil process responses to changes in the functional composition of plant communities. [less ▲]

This cahier aims to identify and analyze the consequences of international migration movements on the school itineraries and aspirations of children who have been exposed to international migration between Mexico and the U. S. Some of these children are active actors of migratory flows because they moved from one country to another. Others are not active migrants; however, given the fact that they belong to divided families due to international migration, they are exposed to the impacts of their family members’ decisions. Consequently, two critical components of their migratory experiences will be the focus of our analysis. Firstly, we will analyze their school trajectory and secondly the family dispersion due to their migratory decisions. [less ▲]

In this paper we propose a new method to approach optimal Traffic Engineering routing. The method consists of dividing the traffic matrix into $N$ sub-matrices, called strata, and route each of these independently. We propose two different implementations of our method in routers. Our method can also be used to compute a very precise approximation of the optimal value of a given objective function for comparison to heuristic Traffic Engineering algorithms. For this application, our algorithm is very efficient on large topologies compared to an LP formulation. [less ▲]
