Une méthode talentueuse : la solution bizarre
Authors: Barth Isabelle , Bobot Lionel
Published: April 2011

Résumé Dans le contexte actuel d’évolution d’attentes et de comportements des salariés (comme la génération Y), les managers expriment leur désarroi à gérer de façon innovante les situations de conflits. Pourtant, de nombreuses pratiques sont régulièrement transmises et enseignées, tant en formations qu’en situations de travail. Elles semblent maintenant marquer leurs limites. Nous faisons l’hypothèse que le recours à des attitudes défiant la logique et le bon sens pourrait conduire à la fin pacifique d’une forme de conflictualité, plus en phase avec l’environnement actuel. Nous avons identifié l’approche développée par les chercheurs de l’ ECOLE PALO ALTO, nommée « solution hors cadre » ou « solution bizarre » en la transposant au monde de l’entreprise, et plus particulièrement au champ du management commercial. Afin de vérifier si cette solution apparait dans la pratique des managers commerciaux nous avons utilisé la méthode des scénarios. Cette méthode, qui consiste à questionner des praticiens sur des situations professionnelles concrètes, permet d’évaluer leur perception de ces situations et apporte ainsi une information riche sur les problèmes rencontrés par les managers. L’objectif de cette recherche est de comprendre, grâce à l’apport des techniques projectives, comment sont gérées les situations de conflit en management commercial, et dans quelle mesure la « solution bizarre émerge ».
Entre crédit public et crédit mutuel : un aperçu des théories du crédit au XIXe siècle
Authors: Chaïbi Olivier
Published: April 2011

Les études sur les théories relatives au crédit au XIX e ont accordé une importance majeure aux économistes britanniques. À l’exception de la doctrine saint-simonienne qui exerça une forte influence dans la mise en place du système bancaire sous le second Empire, la plupart des autres pensées ont été éclipsées. Pourtant, la question du crédit a été âprement débattue en France. Que ce soit au sujet de la légitimité de l’intérêt, de la valeur des taux, du problème de la dette publique ou encore des moyens de stimuler un secteur ou une activité économique, de nombreux auteurs ont exposé des conceptions ou des projets originaux sur le crédit, son rôle et les moyens de l’organiser. Les débats sur ces questions semblent avoir atteint leur paroxysme sous la seconde République en raison de la crise économique et politique que traversa alors le pays. Auparavant, la question du crédit public avait dominé les débats politiques, tandis que la question de la légitimité de l’intérêt continuait de tourmenter les moralistes. À partir du second empire, le développement d’institutions modernes de crédit aux particuliers offre une nouvelle donne. La diminution des taux d’intérêts estompe les querelles sur sa légitimité. Toutefois, l’importance prise par les grandes banques capitalistes inquiète les théoriciens soucieux des questions sociales. Malgré l’échec de la Banque du Peuple de Proudhon, de nombreux théoriciens persistent dans la volonté de créer un organe de crédit des travailleurs. Il en résulta des formes de coopérations bancaires et de crédit mutuel, fruits de plusieurs décennies de théorisation et de maturation.

Published: April 2011

Transistors have been significantly downsized over the past decades, reaching channel dimensions of around 100 nm. In nanoscale, quantum effects start to play a key role in device operation, allowing the development of applications based on new physics. In silicon nanodevices, for instance, the device downsizing is associated with a reduction of the number of impurities (dopants) incorporated in the channel. Dopants can play an active role in device operation, mediating the electron transport between source and drain. Here, we present a new device concept of a memory based on the interaction between dopants in nanoscale field-effect transistors. As a basis for memory operation, we show experimental results of single-electron charging in individual dopants monitored by a single-electron current flowing through a dopant array.

In light of current world economics heading towards a direction that demands a refurbished theoretical guidance, Huang, Mu and Huang’s (1990, 1991) “Overall Development of Global Economics” model - also affectionately known as the "4-ways, 2-forms" hypothesis - serves as a research guideline and a basic framework of economical development problems. Economical development throughout the history of mankind has experienced three phases, each phase bearing its own characteristics. While today’s developing countries linger in the era of nature driven self-sufficiency, developed countries have surged ahead into a phase of post-information economy where information technology serves as the backbone of Information Economic Era. At present, the financial disparities between nations often and inevitably produce conflicts driven by socio-economical differences and the resultant ideologies. What are the orientations in economic development for less developed countries, developing countries and developed countries? Why does conflict between them arise and what causes this? How can they be resolved? These have become focal issues of concern among economist.

Published: April 2011

Green vegetation segmentation in color images is a fundamental issue for automated remote sensing and machine vision applications, plant ecological assessments, precision crop management, and weed control. A simple green vegetation feature extraction method (GVFE) is proposed in this paper to segment the green vegetation from their non-green backgrounds due to the fact that the green component content is always greater than that of the red and blue in RGB color space. The conventional based-auto-threshold method, ExG (Excess Green) was compared with GVFE, in which a green index ratio was defined to evaluate the performance of them. A digital color image set of single Canna flower taken in natural lighting were used to test them. Experimental results have showed that GVFE has superior performance over ExG+auto-threshold in term of stability, and is insensible to illuminant variations.

Published: April 2011

The existence of water affects the mechanical properties of cracked rock mass. Taking into account the friction generated by the crack closure, the stress intensity factor of the center cracked plate subjected to compression and seepage pressure was obtained through the theoretical analysis and numerical calculation of the boundary collocation method. The results show that crack tip stress intensity factor increases with the increasing of the seepage pressure, but decreases with the increasing of crack surface friction and the confining pressure. Finally a failure criterion for cracked rock mass under seepage pressure and confining pressure is developed.

Published: April 2011

The superconducting magnetic energy storage system (SMES) has good characteristics such as high efficiency, quick response, no deteriorations, etc. However it is still far from wide application. The main obstacle is due to its high cost. One of the most effective ways to reduce the cost of SMES is to make it multifunctional. In this paper, a dual mode control strategy is proposed. With the proposed control strategy, The SMES can compensate voltage dip, current harmonics, reactive power, and active power fluctuation with a simple topology. The efficacy of the proposed control strategy is verified by simulation results.

In an adaptive echo canceller, the detection algorithm able to distinguish echo path change (EPC) from double-talk (DT) is vital to ensure that adaptive filter tap coefficients are updated in case of EPC and frozen during the DT period. The paper presents a new echo cancel algorithm, which can protect the adaptive filter performance during double-talk in acoustic echo cancellation of teleconference without setting a detector. A judgment value can be directly used in the iteration formula to control the iteration speed of the filter, which composed of the correlation of the far-end signal and near-end received signal, the pre-correlation of the error signal. The computer simulation results verify that the mentioned algorithm has the good double talk protection performance, and it is very useful and efficient in distinguishing EPC from DT but with less computational complexity contrast to the congener algorithm.
