While benthic and sediment processes are now recognized as major components of the shelf iogeochemical budget, their representation in 3D biogeochemical model has for long been oversimplified [Soetaert et al., 2000]. These oversimplified formulations of the bottom boundary onditions prevent to account for the response of diagenetic processes to the environment. The onsequent absence of spatial and temporal variability of benthic/pelagic fluxes may lead to mis- valuation of important terms in the biogeochemical budgets (e.g. Oxygen, Nitrogen, Carbon, hosphate). More importantly, feedbacks mechanisms within the ecosystem response to utrophication may be overlooked, such as, for instance, the sensitivity of benthic denitrification o the oxygen content in the bottom waters. The GHER-ECO 3D biogeochemical model is xtended ith a refined benthic component explicitly accounting for the effect of organic matter transport, eposition and resuspension and for the influence of the environmental conditions on the iagenetic pathways. A semi-empirical approach allows to reproduce the variability and feedbacks riven by benthic diagenesis without the computational burden of a vertically resolved sediment ayer. This simplification allows to use the coupled model for the long term runs (several ecades) required to appreciate the slow dynamics introduced by the accumulation of organic atter in the sediment layer during the years of high riverine discharge. The extended model has een implemented for the Black Sea North western shelf [Capet et al., 2012]. After a presentation f the main assumptions used to construct the benthic module, re- sults are analyzed with a focus n (1) spatial and seasonal variability of benthic diagenesis and con- sequent benthic/pelagic xchanges, (2) comparison to in-situ estimates of benthic/pelagic dissolved fluxes, (3) implication n biogeochemical budgets and eutrophication issue. Inherent limitations of the semi-empirical pproach are discussed in the perspective of the current challenges addressed to biogeochemical odels. [less ▲]

What is mini-livestock ? Mini- (or micro-) livestock is a term used to group several animal species reared to produce food or feed and of usually smaller size than commonly reared species. Those species include rodents, snails, reptiles, insects, earthworms, etc. Although some authors consider small species and breeds of common livestock (e.g. rabbits or dwarf cattle) as mini-livestock, mini-livestock species should rather be referred to as unconventional species. Capybara, for example, the world’s largest rodent can weigh up to 90 kg which is far more than African sheep and goats whose adult weight varies between 30 and 60 kg. To be considered as mini-livestock, those unconventional species must be reared in some kind of controlled and sustainable system conversely to the mere management and hunting of game in the wild. Why keep mini-livestock instead of conventional livestock? Depending on the context, mini-livestock can have several functions that conventional livestock cannot fulfill or less efficiently. In developing countries, in urban agriculture, where land is scarce or in conflict areas, small livestock species can occupy niches unavailable to larger species. The small size of the animals reduces the financial risk as it is easy to buy, sell or kill one animal of the herd, adapting more efficiently to family’s needs for cash or food. It is also easier to maintain in terms of feed demand. Small animals have usually higher reproductive rates than larger animals. They can be raised by landless farmers harvesting forage on common lands. Finally, as they can be maintained on small farms, they have the potential to increase the productivity of the crops by recycling nutrients from crop residues and kitchen wastes into manure. Another interesting feature of mini-livestock concerns conservation strategies. Using mini-livestock principles, endangered species highly appreciated as game meat or for other purposes (e.g. skins) are domesticated and reared in sustainable ways. This helps reducing pressure on wildlife and gives the farmer access to lucrative niche market. What does BEDIM do to help people busy with mini-livestock? Considering mini-livestock are unconventional species, conversely to cattle, small ruminants, pigs or poultry, few information on rearing systems is available. Nutrition, reproduction, behavior, genetics and health issues, including potential zoonosis, are barely studied and stay unknown. This is a major limitation for the development of mini-livestock and the improvement of the systems efficiency. BEDIM (Bureau for Exchange and Diffusion of Information on Mini-livestock; www.bedim.org) was therefore created by the Professor Jacques Hardouin and his colleagues in the nineties as an international non-profit organization with the goal to stimulate information exchange and research on mini-livestock. Presently, BEDIM members are redefining BEDIM activities in the context of information exchange of the 21st century. One new activity is the award of an annual prize to encourage works done on a topic related to mini-livestock. This award is a tribute to the late Professor André Buldgen, former President of BEDIM.

Until recently, the most common parametric approaches to study the combined effects of several genetic polymorphisms located within a gene or in a small genomic region are, at the genotype level, logistic regressions and at the haplotype level, haplotype analyses. An alternative modeling approach, based on the case/control principle, is to regard exposures (e.g., genetic data such as derived from Single Nucleotide Polymorphisms - SNPs) as random and disease status as fixed and to use a marginal multivariate model that accounts for inter-relationships between exposures. One such model is the multivariate Dale model. This model is based on multiple logistic regressions. That is why the model, applied in a case/control setting, leads to straightforward interpretations that are similar to those drawn in a classical logistic modeling framework. [less ▲]

Starting from the idea of Tsallis on non-extensive statistical mechanics and the q-entropy notion, we recall the Theil index Th and transform it into the Th-q index. Both indices can be used to map onto themselves any time series in a non linear way. We develop an application of the Th-q to the GDP evolution of 20 rich countries in the time interval [ 1950 - 2003] and search for a proof of globalization of their economies. First we calculate the distances between the "new" time series and to their mean, from which such data simple networks are constructed. We emphasize that it is useful to, and we do, take into account different time "parameters": (i) the moving average time window for the raw time series to calculate the Th-q index; (ii) the moving average time window for calculating the time series distances; (iii) a correlation time lag. This allows us to deduce optimal conditions to measure the features of the network, i. e. the appearance in 1970 of a globalization process in the economy of such countries and the present beginning of deviations. The q value hereby used is that which measures the overall data distribution and is equal to 1.8125. [less ▲]

Ce livre s’adresse à toutes les personnes qui a des titres divers sont concernés par l’évaluation des politiques publiques parce qu’ils doivent en assurer la réalisation ou en encadrer la démarche. Les exemples et les angles de discussion sont les plus larges possibles pour que le lecteur puisse s’approprier les outils quel que soit son secteur de responsabilité et quel que soit son territoire. Il trouvera dans la suite des chapitres non pas un livre de recettes – ce qui nous semble contraire à la logique d’évaluation de politiques – mais des cadres de réflexion, des propositions de pratiques, ainsi que des références complémentaires pour développer ses pratiques tout en mobilisant un regard critique.
