Sommario/riassunto

Plus de quatre-vingts contributeurs, spécialistes de sciences humaines et sociales (droit, économie, gestion, histoire, sciences politiques, sociologie) ont travaillé ensemble pour définir les principales notions et termes comptables qui courent du xve siècle à aujourd’hui. L’ouvrage est à même d’intéresser un public varié : les non-spécialistes de la comptabilité à la recherche de l’histoire technique de termes comptables ; les spécialistes de la comptabilité soucieux de trouver matière à réflexion sur les débats contemporains relatifs à la construction du chiffre comptable et de ses enjeux de pouvoir (i.e. : normes comptables internationales IFRS) ; les professionnels du chiffre curieux de l’étymologie et de l’origine des termes comptables et financiers. L’ouvrage vise donc à donner à chacun les moyens de mieux comprendre les enjeux des conventions comptables passées et actuelles et de prendre part aux débats qu’elles suscitent. Il permet de s’approprier ce qui est en général présenté comme une technique aride. Bien au contraire, ce dictionnaire critique met en avant la dimension historique et sociale de la comptabilité et le rôle qu’elle joue dans les transformations successives du capitalisme.  Over eighty contributors human and social scientists (law, economics, management, history, political science, sociology) have worked together to highlight the main accounting concepts and terms coming from the past.

Sommario/riassunto

The purpose of this paper is to answer two questions. The first question is: Is it feasible to use airborne forces to penetrate enemy airspace and to conduct a vertical envelopment to effect deep operational maneuver? If it is feasible, what are the employment options available for the use of such an airborne force in the conduct of a modern military campaign? To examine these questions, the paper begins with some definitions to provide a common frame of reference. The use of airborne forces in World War II is next examined to determine if the use of airborne forces to effect deep operational maneuver is historically feasible. Next, the contemporary threat is



discussed as it is relevant to the employment of airborne forces in a modern context. Next, the feasibility of the use of airborne forces with some limitations to conduct deep operational maneuver is established in the context of the maneuver, firepower, and protection aspects of the combat power model. Next, the theory of deep operations and the use of airborne forces to conduct these kinds of deep maneuvers is examined in the theories of Clausewitz, Jomini, Tukhachevskiy, Triandafillov, and Simpkin. Next, six employment options for the use of airborne forces to conduct deep operations in a modern context are deduced. They are: (1) an airborne force can be used to create a second front within a theater of operations; (2) an airborne force can be used to operationally contain an enemy force targeted for destruction within a theater of operations; (3) an airborne force can be used to seize a "bridgehead"...; (4) an airborne force can conduct coups de main against high value targets within a theater of operations; (5) an airborne force can conduct light operations in a theater of operations to disrupt and disorganize the enemy's rear facilities and networks and have a cumulative operational impact; and (6) an airborne force can conduct expeditionary operations to achieve political, strategic, and operational aims
