When professionals force managers to adopt a decoupling strategy
2015
Top managers in organizations usually adopt a “decoupling” strategy to regulate relations with the professionals whom they employ. The concept of decoupling worked out by Meyer and Rowan (1977) can be used to analyze senior management’s decision to avoid confrontations with professionals by accepting, more or less outright, differences between the institution’s norms and the practices of professionals. Operating in this way is no longer obvious, since managers increasingly interfere in the “business” of professionals. The latter still have resources for countering top management’s strategy of “conformity” with the requirements of institutional representatives ; but they have to put up a fig…
Rachats d’actions annoncés versus rachats réalisés:une analyse du découplage sur le marché français - Announced share repurchase versus repurchase sh…
2011
(VF)Notre analyse originale porte sur la pertinence des explications des rachats d’actions en confrontant les motivations des rachats annoncés au faible taux de rachats effectifs mesuré sur le marché français. Nous mobilisons les principales explications théoriques des rachats d’actions et nous proposons une étude empirique de plusieurs centaines de programmes de rachats afin de justifier l’intention volontaire des dirigeants de ne pas engager des rachats importants en dépit de ceux annoncés provoquant ainsi un découplage. Nous montrons que certaines entreprises ont une probabilité plus élevée de provoquer ce découplage en rachetant plus faiblement leurs propres actions. Ce sont les entrepr…
Spectroscopie des hexafluorures à nombre impair d'électrons
1995
From a theoretical point of view, a tensorial formalism adapted to the study of molecules or octahedral ions with a half-integer angular momentum has been developed for the first time. We have used here the method of projective representations, more consistent than that of double groups. A complete set of coupling coefficients and formulas, as well as the corresponding computing programs have been elaborated. This has firstly allowed to write a simple model describing the vibronic structure of colored hexafluorides. Then, somme applications of this formalism to the study of rovibronic couplings of XY6 molecules in a fourfold degenerate electronic state have been considered, especially conce…
