    This paper examines scientific collaboration between French public research teams and distant partners. We first analyse the role and the development of trust and then, the relation between the degree of sophistication of Information and Communication Technologies (ICT) and the constraint of geographical proximity. In that purpose, we present a typology of the different kinds of knowledge and a classification of technologies. A case study in the field of space physics allows us to confront our theoretical elements to real life. We study the evolution of ICT sophistication parallel to collaboration patterns. Finally, we give some recommendations for public funding of virtual networks.collaboratory, knowledge transfer, trust, ICT classification, space physics

    Regionalismo y educación superior en Suramérica: Un análisis comparadao para entender la internacionalización

    Current region-building projects are crafting higher education governance around the world. In fact, almost every regional scheme has launched programs and policies to promote the coordination, cooperation and/or integration of higher education systems and institutions. This paper focuses in the South American region and develops a comparative analysis of regional schemes, focusing on four cases: the Common Market of the South (Mercosur), the Bolivarian Alliance for the People of Our America – People’s Trade Agreement (Alba-TCP), the Union of South American Nations (UNASUR) and the Pacific Alliance (AP). These regional projects –regardless its ideological orientation– are delivering policies to promote university cooperation, coordination and/or integration. We argue that at least three trends of internationalization of the university are being diffused and consolidated through regionalism: first, a status-quo internationalization (hegemonic); second, a revisionist internationalization; third, a counter-hegemonic internationalization. The Pacific Alliance reveals the first type; Mercosur is the revisionist case; and ALBA-TCP represents an attempt of a counter-hegemonic process. UNASUR is an “in-between” case, as the Atlantic versus Pacific divide has not yet been resumed. We unfold the argument by pursuing a comparative approachLos actuales proyectos de construcción de región están generando modificaciones en la gobernanza de la educación superior en todo el mundo.

    Impact splash chondrule formation during planetesimal recycling

    Full text link
    Chondrules are the dominant bulk silicate constituent of chondritic meteorites and originate from highly energetic, local processes during the first million years after the birth of the Sun. So far, an astrophysically consistent chondrule formation scenario, explaining major chemical, isotopic and textural features, remains elusive. Here, we examine the prospect of forming chondrules from planetesimal collisions. We show that intensely melted bodies with interior magma oceans became rapidly chemically equilibrated and physically differentiated. Therefore, collisional interactions among such bodies would have resulted in chondrule-like but basaltic spherules, which are not observed in the meteoritic record. This inconsistency with the expected dynamical interactions hints at an incomplete understanding of the planetary growth regime during the protoplanetary disk phase. To resolve this conundrum, we examine how the observed chemical and isotopic features of chondrules constrain the dynamical environment of accreting chondrite parent bodies by interpreting the meteoritic record as an impact-generated proxy of planetesimals that underwent repeated collision and reaccretion cycles. Using a coupled evolution-collision model we demonstrate that the vast majority of collisional debris feeding the asteroid main belt must be derived from planetesimals which were partially molten at maximum. Therefore, the precursors of chondrite parent bodies either formed primarily small, from sub-canonical aluminum-26 reservoirs, or collisional destruction mechanisms were efficient enough to shatter planetesimals before they reached the magma ocean phase. Finally, we outline the window in parameter space for which chondrule formation from planetesimal collisions can be reconciled with the meteoritic record and how our results can be used to further constrain early solar system dynamics.Comment: 20 pages, 11 figures, 2 tables; accepted for publication in Icarus; associated blog article at goo.gl/5bDqG

    Networks, Standards and Intellectual Property Rights

    This paper reviews issues that lie at the intersection between intellectual property rights (IPR) and network effects, especially in the context of the global economy. Some of the relevant questions are: (1) How do IPR influence the provision of goods exhibiting network effects? (2) How do network effects in turn influence the creation of intellectual property? And (3) how do aspects of the global economy interact with both IPR and network effects? We synthesize what is known from the existing literature to answer these questions.Intellectual Property Rights, Network Effects, Globalization, Standards, Social Networks, Software Piracy
