    International audience; Orchestras of Digital Musical Instruments (DMIs) enable new musical collaboration possibilities, extending those of acoustic and electric orchestras. However the creation and development of these orchestras remain constrained. In fact, each new musical collaboration system or orchestra piece relies on a fixed number of musicians, a fixed set of instruments (often only one), and a fixed subset of possible modes of collaboration. In this paper, we describe a unified framework that enables the design of Digital Orchestras with potentially different DMIs and an expand-able set of collaboration modes. It relies on research done on analysis and classification of traditional and digital orchestras, on research in Collaborative Virtual Environments, and on interviews of musicians and composers. The BOEUF framework consists of a classification of modes of collaboration and a set of components for modelling digital orchestras. Integrating this framework into DMIs will enable advanced musical collaboration modes to be used in any digital orchestra, including spontaneous jam sessions.

    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.

    la copie déposée est une première version de l'article paru en 2011. Cette publication fait suite au congrès 2005 de AAA à Washington session: "Endangered languages and Linguistic anthropology".; The Añun language (also known as "Parauhano") is still spoken by a few aged individuals, all speaking Spanish in everyday activities and living in lake-dwellings between Maracaibo and the Venezuelan border with Colombia. The territory of the Añun people, disputed ever since the first contacts with the Europeans, has progressively shrunk with the increasing importance of the oil industry. Their linguistic situation, reflected in their oral narratives, takes us back to the power relations experienced by the speakers. Besides providing the community with the widest range of documentation as possible, linguistic anthropology assumes a participative approach, which can help create a partnership between elder speakers and young members of the community, in order to preserve traditional knowledge and develop different aspects of the language and the culture. To be effective, the revitalization of the language should go together with territorial claims and identity recognition.

    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.

    Many data management applications, such as setting up Web portals, managing enterprise data, managing community data, and sharing scientific data, require integrating data from multiple sources. Each of these sources provides a set of values and different sources can often provide conflicting values. To present quality data to users, it is critical to resolve conflicts and discover values that reflect the real world; this task is called {\em data fusion}. This paper describes a novel approach that finds true values from conflicting information when there are a large number of sources, among which some may copy from others. We present a case study on real-world data showing that the described algorithm can significantly improve accuracy of truth discovery and is scalable when there are a large number of data sources.

    Part 6: The Dark Side of Digitalisation; International audience; We advance a structured view of the Futures of Work (FoW) using a futurist’s lens to advance two goals: advancing core dimensions to the FoW while outlining the Futurist’s approach to considering possible futures. Professional futurists point out that they do not predict the future, but rather, build a number of futures – in plural. These views of the futures are presented as scenarios to help decision makers consider alternatives and better understand interactions among the planning dimensions. The scenarios that drive planning are constructed by drawing on characteristics or dimensions that will shape our futures. It is these dimensions that we present here. We offer five foundational dimensions for the FoW, articulating them as opposing perspectives to frame the issue: (1) Virtuality versus Compressed working arrangements; (2) Atomistic work versus Holistic work; (3) Algorithmic versus Human decision-making; (4) Neoliberal capitalism versus Safety-net capitalism; (5) Übermensch versus Nihilists. We use these dimensions to provide scenarios to illustrate their use. We conclude by reflecting on the shock of the 2020 pandemic and the roles of firm size relative to the futures of work.

    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; 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.

    Part 4: Panel; International audience; The field of information systems (IS) has throughout its history experienced extensive changes in technology, research, and education. These renewals will continue into the foreseeable future [10]. It is recognized that IS is a key force in the ongoing societal and organizational renewal and change [2, 8, 14]. For example, in the US business sector, IS continues yearly to consume about 30% of total investments made [5]. Recent research document that IS supports the creation of business value, with particular emphasis on an organization’s innovation and change capabilities [1, 3]. Traditionally, research in IS has been interdisciplinary in nature - since it draws on innovation theory, models of value creation, actors’ roles and behaviors, the creation and running of task oriented groups, and how these relate to organizational structures and mechanisms [24]. Throughout its history the question of benefits from investing in IS has been lively discussed.
