A SPECIFIC COBB-DOUGLAS MODEL AND THE PERFORMAMNCE OF PUBLIC ADMINISTRATION IN THE FRAMEWORK OF MANAGEMENT CONTROL MECHANISM

The position of public administrations at the centre of major socio-economic development projects means that these administrations are strongly requested to perform their productivity mechanisms. Any failure affects systematically development and society, explaining why management control is an essential tool for mitigating risks and failures and increasing the performance and productivity possibilities of these administrations. Thus, management control will be considered through a carefully proposed Cobb-Douglas model adapted to the public sector of the Moroccan administration. The importance and the originality of this work reside respectively in the scientific engineering position of the Cobb-Douglas formalism and in the interpretation that we give to the production scale factors K and L for a rational and reliable adaptation

Toric Geometry and String Theory Descriptions of Qudit Systems

In this paper, we propose a new way to approach qudit systems using toric geometry and related topics including the local mirror symmetry used in the string theory compactification. We refer to such systems as (n,d) quantum systems where $n$ and $d$ denote the number of the qudits and the basis states respectively. Concretely, we first relate the (n,d) quantum systems to the holomorphic sections of line bundles on n dimensional projective spaces CP^{n} with degree n(d-1). These sections are in one-to-one correspondence with d^n integral points on a n-dimensional simplex. Then, we explore the local mirror map in the toric geometry language to establish a linkage between the (n,d) quantum systems and type II D-branes placed at singularities of local Calabi-Yau manifolds. (1,d) and (2,d) are analyzed in some details and are found to be related to the mirror of the ALE space with the A_{d-1} singularity and a generalized conifold respectively.Comment: 12 pages,latex, 2 figures.
