MULTISCALAR CLUSTERS AND NETWORKS AS THE FOUNDATIONS OF INNOVATION DYNAMICS IN THE BIOPHARMACEUTICAL INDUSTRY
Based on the case of the biopharmaceutical industry, the aim of this paper is to challenge the core conviction now widespread within the âspatial clustering theoryâ, which devotes a key (if not exclusive) role to geographical proximity in explaining clustering dynamics of innovation activities within spe-cific territories. Our argument is threefold. First, mere geographical proximity is not enough; in many cases, cognitive, organizational and strategic forms of proximity are often at least as crucial as the topological closeness among inno-vation actors. Second, our idea is that clusters are fundamentally the territoria-lized outcome of combinations of inter-organizational and social networks among actors pursuing common goals, each of these actors having a specific territorial and social embedding that allows him or her (or not) to operate and interact at different spatial scales. These networks are socially and territorially embedded, but they can operate at various spatial scales. Third, sector-driven dynamics â as is in the case of biopharmaceuticals â may structurally frame the way the actors interact and collaborate in R&D projects and innovation proce-sses. Indeed, the dynamics underlying the emergence, structuring and evolution of biopharmaceutical clusters are both multi-actor and multiscalar. In this perspective, clusters and networks appear to be intertwined phenomena, con-substantial one to each other, and co-evolving organizational modes of biop-harmaceutical innovation.BIOCLUSTERS, FORMS OF PROXIMITY, INNOVATION NETWORKS, SPATIAL SCALES

Using bacteriophages and antibiotics in combination to control pathogenic bacteria
Multidrug resistance (MDR) is becoming an increasing threat to the global public health and Pseudomonas aeruginosa is one of the leading causes of nosocomial infections as it can quickly develop resistance to clinical antibiotics. The rise of MDR has rejuvenated interest in alternative therapies where, for example, pathogen-specific phages could be used on their own or alongside antibiotics to improve treatment efficacy. Benefits of phages include high pathogen specificity, efficacy against antibiotic-resistant bacterial genotypes and their ability to co-evolve to overcome evolution of phage resistance. Phages also have low toxicity to the patients, minimal disruption of the patientâs microbiota, and can auto- âdoseâ themselves by replicating in their host pathogens. This research investigates using phages and antibiotics in combination therapy in vitro against the Pseudomonas aeruginosa bacterial pathogen. The main aim was to identify effective phage-antibiotic combinations using various commonly used clinical antibiotics and LPS and pilus-targeting phages that have been shown to be effective against P. aeruginosa previously. Results show that certain combinations of antibiotics and bacteriophages are more efficient at suppressing bacterial growth than the others. Specifically, it was found that antibiotic combinations retain their synergies, antagonistic or not, even when phages are added. Furthermore, we show that two bacteriophages alongside one antibiotic is likely to be the best combination for designing efficient phage-antibiotic therapy cocktails. Interestingly, antibiotic-phage synergies were different when applied against clinical P. aeruginosa strains. Together, these results suggest further research on combination therapies aimed to suppress bacterial growth is needed, and specifically, combinations therapies need to be tested not only against laboratory but also against clinical strains to obtain effective outcomes

la responsabilité globale des entreprises du service public marchand : vers un élargissement de la notion de responsabilité sociale et environnementale
Ce document cherche Ă identifier les pratiques responsables des services publics marchands (SPM), prĂ©misses dâune responsabilitĂ© plus « globale » des entreprises (au sens plus large du terme). Ces entreprises du SPM, qui ont eu lâhabitude de gĂ©rer des conflits contradictoires entre leurs missions de service public et leurs impĂ©ratifs de rentabilitĂ©, dĂ©veloppent aujourdâhui des solutions innovantes pour coordonner les intĂ©rĂȘts divergents de leurs parties prenantes. Cet article met ainsi en Ă©vidence lâexistence dâune autre conception de la RSE (responsabilitĂ© sociale et environnementale de lâentreprise) relativement peu (voire pas du tout) traitĂ©e par la littĂ©rature Ă©tudiant cette question " This paper tries to identify French for-profit public servicesâ sustainable business strategies which could lead to a âglobalâ responsibility (i.e. an economical, social and environmental responsibility). These organizations have always managed contradictory aims between their public missions and their profitability. They try to develop new solutions in order to coordinate the contradictory objectives of their stakeholders. This paper highlights the existence of another conception of Corporate Social Responsibility (CSR).public sector, enterprise, social, environmental responsability
Les clusters et les reseaux comme fondements de la dynamique d'innovation dans l'industrie biopharmaceutique (Clusters and networks as the foundations of innovation dynamics in the biopharmaceutical industry)
Pour rendre compte des phĂ©nomĂšnes de rĂ©ticularisation et dâagglomĂ©ration croissantes des activitĂ©s dâinnovation, de nombreux travaux empiriques et thĂ©oriques dans diverses disciplines (Ă©conomie, sociologie, gĂ©ographie, management) ont soulignĂ© lâimportance des logiques de proximitĂ©. Câest dans ce cadre que sâest forgĂ©e lâidĂ©e que câest au sein des clusters que se gagne dĂ©sormais la compĂ©tition induite par les dynamiques dâinnovation soutenue et de globalisation rapide, notamment dans les secteurs high-tech. Toutefois, en dĂ©pit dâune trĂšs large diffusion, cette conviction manque aujourdâhui encore dâassise thĂ©orique et empirique. Ă partir du cas de la biopharmacie, cet article cherche ainsi Ă montrer que si les clusters sont une des conditions permissives du processus de production et de diffusion de lâinnovation, ils nâen constituent pas pour autant une condition suffisante, ni mĂȘme forcĂ©ment la forme organisationnelle et spatiale la plus adaptĂ©e, en particulier dans un contexte de plus en plus incertain et globalisĂ©. In order to explain why innovation activities are increasingly structuring through networking and agglomeration dynamics, numerous empirical and theoretical works in various disciplines (economics, geography, sociology, management) have stressed the crucial role of spatial proximity. Following this conviction, the idea has emerged that âclustersâ has become the key competitive tools within a context of sustained innovation dynamics and rapid globalization, notably in high-tech industries. However, despite its wide spread among academics and practitioners, this conviction still lacks solid theoretical and empirical foundations. Drawing from the case of biopharmaceuticals, this paper aims at showing that if clusters are one of the keys of the processes underlying innovative activities and the diffusion of innovations, they are far from constituting a sufficient condition or even more necessarily the appropriate organizational and spatial form of these processes, particularly in a context of globalization and growing uncertainties.Bioclusters, Emergence and Structuring Dynamics, Forms of Proximity,Innovation Networks, Spatial Scales
De la responsabilité sociale des acteurs
Nous montrons ici, sans prĂ©tendre Ă lâexhaustivitĂ©, quels sont, au-delĂ des (grandes) entreprises, les autres acteurs intĂ©ressĂ©s Ă rĂ©clamer leur part de responsabilitĂ© vis-Ă -vis du dĂ©veloppement durable. Nous nous demandons quelles sont leurs motivations, leurs objectifs et leurs moyens dâaction, et si ces moyens sont les mĂȘmes pour tous les acteurs. Le mouvement de revendication dâune responsabilitĂ© de la part de nombreux acteurs est replacĂ© dans le cadre plus gĂ©nĂ©ral des Ă©volutions (Ă©conomiques, sociales, environnementales, gĂ©opolitiques, etc.) des trente derniĂšres annĂ©es. La premiĂšre section de cet article explique lâĂ©mergence de la notion de responsabilitĂ© des acteurs (RSA), clarifie les relations entre RSA et dĂ©veloppement durable, puis montre les variantes gĂ©ographiques de la RSA. La seconde section sâattache aux diffĂ©rents acteurs de la RSA et compare leurs objectifs et moyens dâaction
