Negative responses to strategic innovation, a case study of record labels facing streaming
2021
Record labels are organizations in charge of phonographic production at the interface between musicians and the audience. Since the arrival of digital technologies such as the mp3 and the Internet, record labels have had to adapt to several changes: wider distribution channels, dematerialized competitors, customers’ demands for free music, more ephemeral cooperation. Specifically, streaming platforms like Spotify brought a major change known as a strategic innovation. A strategic innovation is a strong change that overturns all previously established values in the sector (renewal of values attached to the product, values attached to the customer relationship and power relations). However, f…
Bioavailability of inorganic arsenic in cooked rice: practical aspects for human health risk assessments.
2005
Arsenic is present in rice grain mainly as inorganic arsenic. Little is known about the effect of cooking on inorganic arsenic content in rice and its bioavailability. This study evaluated total arsenic and inorganic arsenic in rice cooked with arsenic-contaminated water, the bioaccessibility of As(III) and As(V) after simulated gastrointestinal digestion, and the extent of arsenic retention and transport by Caco-2 cells used as a model of intestinal epithelia. After cooking, inorganic arsenic contents increase significantly. After simulated gastrointestinal digestion, the bioaccessibility of inorganic arsenic reached 63-99%; As(V) was the main species found. In Caco-2 cells, arsenic retent…
Failure of the normalization of the RAS method : absorption and fabrication effects are still incorrect
2000
The r and s vectors of the RAS method of updating matrices are presented often as corresponding to an absorption effect and a fabrication effect. Here, it is proved that these vectors are not identified, so their interpretation in terms of fabrication and absorption effect is incorrect and even if a normalization was proposed to remove underidentification, this normalization fails and poses many difficulties..

Les organisations publiques : des institutions communicantes ? Le cas des Caisses d'Allocations Familiales
2009
L’objectif de cet article est de proposer une approche comprehensive de la communication des organisations publiques a travers le cas des Caisses d’Allocations Familiales (CAF). Les travaux dont il est issu ont eu pour objet d’interroger les representations des cadres, charges de communication et directeurs des CAF autour de la notion d’institution communicante. Il s’agit notamment de preciser si celle-ci releve d’un artefact ou pourrait -et a quelles conditions- constituer un modele valide pour analyser la communication des organisations publiques.

Valeur boursière versus valeur comptable
2011
International audience; Cet article a pour objet d’apporter une explication à l’écart constaté entre la valeur comptable et la valeur boursière des sociétés. Nous avons supposé qu’il peut être expliqué par l’irrationalité et « l’auto-référentialité » du marché, ainsi que par l’incapacité du modèle comptable traditionnel à traduire la valeur de la firme. Nos résultats corroborent la majorité de nos hypothèses et montrent que la distorsion entre la valeur comptable et la valeur boursière est une conséquence directe de la comptabilité au coût historique, de la prudence comptable, de la non-activation des certains éléments immatériels, ainsi que de la mauvaise évaluation (mispricing) des titres…
The need for information in purchase situation and the information behavior in front of the shelf : use and effects of electronic interactive communi…
1999
The classic approach of buying behavior supposes that the consumption value derives from the evaluation of the technical, functionnal and symbolic features of the product. But, most of recents works use an experiential approach, for which the anticiped situation of consumption or use and the self concept are the essential elements of the consumption value. This thesis, devoted to information behavior in buying situation, attemps to conciliate these two paradigms until here opposite. The first part of this search investigates the concept of need for information. Its results, according to us, the activation ot two schemes, the first concerning the product acquisition, the second relative to t…
