METRICS

Metrics are a sine qua non condition of an efficient management. Indeed, management cannot be based upon intuition: it has to be underpinned by figures.\ud \ud The choice of the indicators, their link to objectives and their strategic value, the weight to be assigned to them in terms of performance and cascading accountabilities imply considering:\ud \ud - outputs vs outcomes\ud - short term vs long term\ud - suboptimization vs global optimization\ud - lagging vs leaders indicators\ud \ud New metrics methods in management are doomed to give priority to effectiveness over efficiency.\ud \u

Dragged Metrics

We show that the path of any accelerated body in an arbitrary space-time geometry $g_{\mu\nu}$ can be described as geodesics in a dragged metric $\hat{q}_{\mu\nu}$ that depends only on the background metric and on the motion of the body. Such procedure allows the interpretation of all kind of non-gravitational forces as modifications of the metric of space-time. This method of effective elimination of the forces by a change of the metric of the substratum can be understood as a generalization of the d'Alembert principle applied to all relativistic processes

On Special Berwald Metrics

In this paper, we study a class of Finsler metrics which contains the class of Berwald metrics as a special case. We prove that every Finsler metric in this class is a generalized Douglas-Weyl metric. Then we study isotropic flag curvature Finsler metrics in this class. Finally we show that on this class of Finsler metrics, the notion of Landsberg and weakly Landsberg curvature are equivalent
