External Changes and R&I Inter-Organizational Network Dynamics: The Case of EU R&I Policy Change
2022
The paper seeks to understand in what way changes in EU innovation policy incentives affect the EU R&I inter-organizational network dynamics. In particular, the study’s empirical settings are the two innovative inter-organizational networks that connect knowledge actors financed through two EU Framework Programs: the 7th Framework Program (or FP7), and the 8th Framework Program, named HORIZON 2020 (or H2020). Using a dataset of more than 22,228 unique projects in FP7 and 22,153 in H2020, we constructed two collaboration networks. We apply network analysis as a research instrument to identify and measure the fundamental structural properties and evolutionary dynamics of whole networks. I…
Fonds de retraite et performance : la famille compte-t-elle ?
2008
(VF)Actuellement, la majorité des fonds mutuels ou des fonds de pension appartient à une famille. Une famille comprend les fonds gérés par la même société. Cet article s’intéresse à la performance des fonds de pension anglais à cotisations définies sur longue période. La performance est mesurée du point de vue de la famille de fonds. Ce changement de niveau d’analyse amène à s’interroger sur l’influence de la taille et donc de la complexité organisationnelle des sociétés de gestion de portefeuille sur leur performance. Autrement dit, les petites familles présentent-elles des performances supérieures à celles des grandes familles? (VA)Almost all mutual funds or pension funds belong to a fami…
The experience of risk in families: conceptualisations and implications for transformative consumer research
2014
International audience; Families represent an important context for understanding and addressing the various forms of risk experienced by consumers. This article defines and discusses the concept of risk as it applies to the familial unit, with a particular focus on the liminal transitions that occur within families and the resiliency required for families to identify and adopt effective coping strategies to manage these transitions. A framework is proposed that offers researchers an approach for applying concepts related to family risk to various consumption-related problems and issues. This framework constitutes a starting point that can be developed and expanded to facilitate a deeper un…
In-mouth mechanism leading to the perception of fat in humans: from detection to preferences. The particular role of saliva
2013
In humans, the perception of fat in food is a complex process involving many sensory modalities (texture, aromaand flavour). Themouth is the first place in which the process of digestion begins. During this process, a bolus is formed in which saliva is significantly incorporated. For solids and semi-solid fatty matrices, saliva and the shear forces applied during mastication contribute to their breakdown and/or destabilisation in emulsified systems. These mechanisms are often dependent on the fat content of the food and thus play an important role in not only the perception of texture but also the release of compounds responsible for the flavour of “fat”. In addition, saliva is directly inv…
La fidélité des consommateurs : une tentative de synthèse
2008
The aim of this article is to offer a synthesis of a very important concept in marketing. After having analysing the definitions of loyalty and their evolution, an overview of theoritical explanation is presented and four main processes based on different theories are identified. The aim is to understand how these theories can be integrated in a general model, in order to open up new avenues of thought.
Assessment of cross-flow filtration as microalgae harvesting technique prior to anaerobic digestion: Evaluation of biomass integrity and energy demand
2018
[EN] In the present study, the effect of cross-flow filtration (CFF) on the overall valorization of Chlorella spp. microalgae as biogas was assessed. The effect of CFF on microalgae cell integrity was quantified in terms of viability which was correlated with the anaerobic biodegradability. The viability dropped as the biomass concentration increased, whereas anaerobic biodegradability increased linearly with the viability reduction. It was hypothesized that a stress-induced release and further accumulation of organic polymers during CFF increased the flux resistance which promoted harsher shear-stress conditions. Furthermore, the volume reduction as the concentration increased entailed an …
Autofinancement, information et connaissance.
2007
L'objectif de cette note est d’analyser les limites de la notion d’autofinancement dans la théorie financière traditionnelle fondée sur la notion d’asymétrie d’information et d’explorer comment l’adoption d’une perspective cognitive permet d’identifier de nouvelles pistes pour mieux comprendre les déterminants de l’autofinancement.
