On Temporal Aspects in Cross-Cultural e-Collaboration Between Finland and Japan Research Teams
2018
Time is an essential dimension in cross-cultural e-collaboration among research project teams. Understanding temporal aspects and project dynamics in cross-cultural research e-collaboration and related processes can improve team members' skills in cross-cultural communication and increase their cultural competence. The present case cultures are Finnish and Japanese, and the case universities are the University of Jyväskylä (Finland) and Keio University (Japan). Three issues are addressed in this article. First, cultural dimensions and time models in the cross-cultural e-collaboration context are discussed. Second, temporal aspects related to e-collaboration activities are introduced. Third,…
Invisible streams : Process-thinking in Arendt
2016
For Hannah Arendt, some of the most distinctive features of the modern age derived from the adoption of a process-imaginary in science, history, and administration. This article examines Arendt’s work, identifying what it calls the ‘process-frame’ in her criticism of imperialism, economy, and the biologization of politics. It discusses an interpretation in which ‘natality’ presents a completely alternative mode of temporality, a resistance to the process-frame. This interpretation, it is argued, needs to be specified by taking into account that political action both interrupts and starts processes of its own. To confine and overcome the negative effects of process-framing, it is important t…
Caractérisation fine du climat en serre expérimentale - Cas de la plateforme 4PMI de l’INRA de Dijon
2019
Les conditions environnementales dans lesquelles sont cultivées les plantes influent grandement surleurs caractéristiques observables, i.e. leur phénotype. Les conditions environnementales d’une serren’étant pas homogènes, elles peuvent induire un biais lors de l’analyse des résultats de phénotypage.Afin de mieux contrôler ce biais, la plateforme « Plant Phenotyping Platform for Plant Micro-organismsInteractions » (4PMI) hébergée par le Centre INRA de Dijon a mis en place un système decaractérisation du climat de chaque plante dans ses serres. Le développement de ce protocole a faitl’objet de ce stage. Dans un premier temps un système de collecte et de gestion des donnéesclimatiques produit…
High-Frequency and Ultra-High Frequency Ultrasound: Musculoskeletal Imaging up to 70 MHz
2020
AbstractMusculoskeletal (MSK) ultrasound has well-established advantages, able to investigate very small structures with high resolution and a quick and real-time dynamic evaluation with the possibility of contralateral comparison. Thus ultrasound has kept its own almost exclusive fields of application in daily clinical practice, and it is considered the first-level imaging technique to assess tendons, bursae, and capsuloligamentous structures of small peripheral joints as well as peripheral nerves. Up to now, however, clinical MSK ultrasound imaging could not go beyond the first 1 to 2 cm under the skin, using high-frequency probes up to 18 to 20 MHz with spatial resolution just below mill…
Thermo-Mechanical Behaviour of Flax-Fibre Reinforced Epoxy Laminates for Industrial Applications
2015
The present work describes the experimental mechanical characterisation of a natural flax fibre reinforced epoxy polymer composite. A commercial plain woven quasi-unidirectional flax fabric with spun-twisted yarns is employed in particular, as well as unidirectional composite panels manufactured with three techniques: hand-lay-up, vacuum bagging and resin infusion. The stiffness and strength behaviours are investigated under both monotonic and low-cycle fatigue loadings. The analysed material has, in particular, shown a typical bilinear behaviour under pure traction, with a knee yield point occurring at a rather low stress value, after which the material tensile stiffness is significantly r…

Effect of oil lamination between plasticized starch layers on film properties
2016
International audience; To reduce the hygroscopic character of biodegradable starch-based films, rapeseed oil was incorporated by lamination (starch-oil-starch 3-layers technique). The lipid lamination followed by starch solution casting step induced an emulsion type structure of dried films. Composite films are more opalescent and glossier than fatty free starch films. For all the films, structure is heterogeneous in the cross-section only. Adding fat induced a twice decrease of the tensile strength. Thermal gravimetry analysis did not show differences between films with and without oil. Lipid reduced the moisture absorption particularly at higher RH as well as the surface swelling index, …
Understanding the White-Emitting CaMoO4 Co-Doped Eu3+, Tb3+, and Tm3+ Phosphor through Experiment and Computation
2019
In this article, the synthesis by means of the spray pyrolysis method, of the CaMoO4 and rare-earth cation (RE3+)-doped CaMoO4:xRE3+ (RE3+ = Eu3+, Tb3+, and Tm3+; and x = 1, 2, and 4% mol) compounds, is presented. The as-synthesized samples were characterized using X-ray diffraction, Rietveld refinement, field emission scanning electron microscopy (FE-SEM), Raman spectroscopy, and photoluminescence (PL) spectroscopy. To complement and rationalize the experimental results, first-principles calculations, at the density functional theory level, have been performed to analyze the band structure and density of states. In addition, a theoretical method based on the calculations of surface energie…
Local and territorial determinants in the realization of public–private–partnerships: an empirical analysis for Italian provinces
2019
ABSTRACT Relational networks and intangible factors are crucial elements for the competitiveness of a territory. Public–Private–Partnerships (PPPs), in particular, allow for the provision of goods and services that favour the exploitation of complementarities between public and private resources. They aim at promoting an increase in the overall efficiency of investment projects through a complex mechanism that distributes risk and revenues among stakeholders. This paper examines the local and territorial determinants of PPPs through an econometric analysis based upon Italian municipal data, grouped at the provincial level. Using a tobit model, we analyse the relationship between the realiza…
Les enjeux de la professionnalisation des agents de développement. L’ingénierie territoriale prise en étau entre les conceptions organique et mécanis…
2011
International audience; Cet article relie les mécanismes de régulation de l’action publique territoriale à des enjeux de professionnalisation des agents de développement, acteurs pivot de l’ingénierie territoriale. Ceux-ci, inscrits dans des communautés épistémiques, posent les jalons d’une régulation pragmatique de l’action publique.Cependant, le registre concurrentiel de l’excellence territoriale couplé aux nouvelles formes de contrôles bureaucratique transforme les territoires de projet en segments d’exécution de politiques définies par des agences regroupant expertise et gestion. Au final, la personnalité bureaucratique des agents de développement l’emporte sur leur rôle d’ « agitateurs…
