International audience; Over the long run, sustained growth is central to poverty reduction. The rapid growth seen in much of the world over the past few decades — notably, but not only, in China and India — has led to an unprecedented reduction in poverty. And, in general, increases in per capita income tend to translate into proportionate increases in income of the poor. As Dollar and Kraay (2002) memorably put it, “Growth Is Good for the Poor.” All the more reason, then, to place sustainability of growth at the center of any poverty reduction strategy.

International audience; We investigate the ordinal invariants height, length, and width of well quasi orders (WQO), with particular emphasis on width, an invariant of interest for the larger class of orders with finite antichain condition (FAC). We show that the width in the class of FAC orders is completely determined by the width in the class of WQOs, in the sense that if we know how to calculate the width of any WQO then we have a procedure to calculate the width of any given FAC order. We show how the width of WQO orders obtained via some classical constructions can sometimes be computed in a compositional way. In particular this allows proving that every ordinal can be obtained as the width of some WQO poset. One of the difficult questions is to give a complete formula for the width of Cartesian products of WQOs. Even the width of the product of two ordinals is only known through a complex recursive formula. Although we have not given a complete answer to this question we have advanced the state of knowledge by considering some more complex special cases and in particular by calculating the width of certain products containing three factors. In the course of writing the paper we have discovered that some of the relevant literature was written on cross-purposes and some of the notions re-discovered several times. Therefore we also use the occasion to give a unified presentation of the known results.

This chapter examines Leibniz’s complex relations to Descartes. These relations are deeply influenced by the evolution of the intellectual context from the beginning of the 1670s to the early eighteenth century. Beyond Leibniz’s overall appraisal of Descartes’s philosophy, there are three areas that stand out in which the discussion and criticism of Descartes’s ideas played a decisive role in the development of Leibniz’s thought: epistemology, natural philosophy, and philosophy of mind. There are three central issues at stake between the two philosophers: the nature and role of evidence, the use of final causes, and the Law of Continuity.

International audience; This chapter introduces several state of the art techniques that could help to make deep underwater archaeological photogrammetric surveys easier, faster, more accurate, and to provide more visually appealing representations in 2D and 3D for both experts and public. We detail how the 3D captured data is analysed and then represented using ontologies, and how this facilitates interdisciplinary interpretation and cooperation. Towards more automation, we present a new method that adopts a deep learning approach for the detection and the recognition of objects of interest, amphorae for example. In order to provide more readable, direct and clearer illustrations, we describe several techniques that generate different styles of sketches out of orthophotos developed using neural networks. In the same direction, we present the Non-Photorealistic Rendering (NPR) technique, which converts a 3D model into a more readable 2D representation that is more useful to communicate and simplifies the identification of objects of interest. Regarding public dissemination, we demonstrate how recent advances in virtual reality to provide an accurate, high resolution, amusing and appropriate visualization tool that offers the public the possibility to ‘visit’ an unreachable archaeological site. Finally, we conclude by introducing the plenoptic approach, a new promising technology that can change the future of the photogrammetry by making it easier and less time consuming and that allows a user to create a 3D model using only one camera shot. Here, we introduce the concepts, the developing process, and some results, which we obtained with underwater imaging.

Genome-wide screens are a powerful technique to dissect the complex network of genes regulating diverse cellular phenotypes. The recent adaptation of the CRISPR-Cas9 system for genome engineering has revolutionized functional genomic screening. Here, we present protocols used to introduce Cas9 into human lymphoma cell lines, produce high-titer lentivirus of a genome-wide sgRNA library, transduce and culture cells during the screen, isolate genomic DNA, and prepare a custom library for next-generation sequencing. These protocols were tailored for loss-of-function CRISPR screens in human lymphoma cell lines but are highly amenable for other experimental purposes.

International audience; This introductory chapter discusses the challenge of fostering sustainable development in Asia, where the economic, social and environmental contingencies are changing rapidly and concerns over, inter alia, climate change, environmental degradation, population growth and social deprivation provide for a complex terrain for decision-making. A number of perspectives that have been used in the extant literature to explain the specific societal role of business organisations in this region are critically reviewed and an emphasis is placed on their general lack of depth and contextualisation. This leads to the observation that this volume represents a timely contribution to our understanding of an understudied phenomenon: corporate sustainability-oriented practices in Asia. The book develops a collection of illustrative company cases that help us to clarify some conceptual and practical issues that surface the societal role of multinational companies in the Asian context. We hereby join a growing movement of research that seeks to unveil the conditions giving rise to a better and more context-sensitive way of integrating concerns for social and environmental impacts into corporate management decisions.

International audience; The study area mainly includes the continental shelves of two European states (France and Spain), three North African countries (Algeria, Morocco and Tunisia), and Gibraltar and Monaco. Overall, the total shelf area in the western Mediterranean down to the 150 m isobath is 208,000 km2 within a total basin area of 1,343,620 km2. There is a major difference in the degree of available information from EU member states and North African countries.

International audience; This chapter provides a critical analysis of the evidence for technical activity specialization in the European Upper Paleolithic by sex. It reviews the arguments based on the kind of evidence researchers are likely to collect (e.g., direct, indirect, and analogical). Some hypotheses are based on suppositions generated by ethnographic comparisons, while others rely on direct or indirect indices (task diversification, activity zone locations, skill level identification, diversity of grave goods, and body evidence like handprints and skeletons). The aim of this chapter is to show that there was a reasoned distribution of activities within groups, accompanied by an emerging social hierarchy, but that it is very difficult to account exactly for what women and men did. And even if we suspect that some tasks were respectively performed by males or females, it is possible that there was also a certain amount of technical specialization that was not related to gender.

International audience; The relative efficiency of auctions and negotiations is still a puzzle in the literature. While auctions are the prescribed procedures and the most used ones for public procurement, in the private sector, where buyers are free to choose their purchasing method, competitive tendering is far from being their preferred option (Bajari et al. 2009). In addition, recent empirical studies (Estache et al. 2009, Bajari et al. 2009) highlight some failures of auction procedures and identify conditions under which negotiation is more efficient. In particular, they show that auctions perform poorly when projects are complex. In this paper, our aim is to contribute to this debate by providing an empirical analysis of how awarding mechanisms are chosen in public procurement in France. To this end, we examine a comprehensive database of 76,188 observations corresponding to the entire set of public procurement work contracts awarded between 2005 and 2007 in the construction sector. We find empirical regularities regarding the choice of awarding procedures by public buyers. However, most of these regularities do not coincide with what the theoretical literature considers as transaction-cost minimizing behaviours. In particular, the size of the construction projects as well as the length of contracts do not appear as key determinants of the choice of awarding procedures, which translates into costly renegotiations.
