Successful corporate turnarounds occur, thus avoiding liquidation, but historical examples are few. In late nineteenth century France Henri Fayol became managing director (CEO) of a vertically integrated iron and steel firm and made various decisions that retrieved the firm from the brink of liquidation. In examining his career, the competitive nature of the industry, and his decisions, it is suggested that he employed a deliberate and comprehensive corporate strategy to guide the firm toward its objectives. While he developed his theory of management from these experiences and claimed that its application was the primary cause of the turnaround, this paper suggests that there were several other factors at work.

This paper aims to model a three-dimensional twisted geometry of a twisted pair studied in an electrostatic approximation using only two-dimensional (2D) finite elements.

The proposed method is based on the reformulation of the weak formulation of the electrostatics problem to deal with twisted geometries only in 2D.

The method is based on a change of coordinates and enables a faster computational time as well as a high accuracy.

The effectiveness of the adopted approach is demonstrated by studying different configurations related to the IEC 60851-5 standard defined for the measurement of the electrical properties of the insulation of the winding wires used in electrical machines.

Many relationships between politicians and bureaucrats are based on an energy‐equilibrium model where the politicians provide energy and the bureaucrats, equilibrium. According to this model, conflicts occur when one partner does not adequately fulfill his or her expected role. This model may be fruitfully used to study the relationship between the politician, the career bureaucrat, and the political appointee. The division of roles among this “ménage à trois” is particularly difficult and often generates tension. The situation is most prone to conflict when the government is in a period of change. At such times, the newly elected politicians have a tendency to mistrust the established bureaucracy and to depend almost exclusively on their political appointees. The dysfunctions induced by this phenomenon, in regard to the capacity of the bureaucracy to adequately fulfill its equilibrium role, are very clearly illustrated by the Canadian political transition of 1984, when the federal government was handed over to the Progressive Conservative Party. A series of interviews with ministers, senior civil servants, and senior policy advisors, all of whom had ringside seats to this transition, shows how the extensive power granted to ministerial offices aggravated the difficulties usually associated with a period of transition. This particular transition illustrates how important it is for the newly elected to ensure that their partisan policy advisors play their roles without getting in the way of the indispensable cooperation which must be established between ministers and senior civil servants.

Past research on collectivist-democratic organizations has attributed their distinctiveness to their socio-political goals and democratic decision-making and largely ignored their work processes. This ethnographic study examines how such organizations resist alienating forms of work even in the face of direct competition with for-profit companies. It focuses on Scopix, a French cooperative sheet-metal factory where the first author spent one year as a shop-floor worker. Cooperators there developed various practices to retain an emancipatory dimension to their work, regularly putting forward “craft ethics” as a counterweight to the sheet-metal industry’s drive to rationalize work processes. Drawing on the sociology of worth, the authors analyze how these practices emerged from the arrangements that workers made between the industrial world on the one side and the domestic and inspired worlds on the other. This study contributes to the literature into two main ways. First, the authors refine the sociology-of-worth framework by conceptualizing the emancipatory dimension of work as the result of ad hoc arrangements between different worlds. Second, the authors highlight the need for the literature on collectivist-democratic organizations to increase its focus on work, introducing the concept of work degeneration as a step in that direction.

Currently, the European air transport system is experiencing an annual growth of 7%. With an increasing number of flights, airports are reaching their capacity limits and are becoming a bottleneck in the system. Mantea is a European Commission funded project dealing with this issue. This paper focuses on planning decision support tools for airport traffic controllers.

The objective of our planning tools is to achieve a better use of the available airport infrastructure (taxiways and runways). To generate a safe plan, many rules must be taken into account that restrict the usage of airport tarmac: international regulations, airport operational procedures, aircraft performance, weather conditions and sometimes even controller “usual practices”. To generate a realistic plan, extensive monitoring of the traffic situation as well as suitable timing must be achieved. In the life cycle of a flight, 11 out of 15 possible causes of delay occur in an interval of 10-20 minutes, between aircraft start-up request and push-back. This means that precise planning before the end of this period is highly improbable. On the other hand, planning after this period implies the need for fast responses from the system.

In the Mantea project, an architecture is proposed in which a co-operative approach is taken towards planning aircraft movements at the airport. Controllers will be supported by planning tools that help assigning routes and departure times to controlled vehicles, in planning runway allocation (departure sequence) and occupancies, and in monitoring plan progress during flight phases. The planning horizon relates to medium term operations, i.e. 2-20 minutes ahead. The Mantea planning tools implement the following functions: runway departure planning, routing, and plan conformance monitoring. The tools will reduce the controller's workload, increase the level of safety for airport surface movements, and reduce the number of delays and operating costs for the airliners.

In this paper, we will focus on the constraint satisfaction programming techniques used in Mantea for (1) runway departure planning, (2) itinerary search and taxi planning functions. The airport tarmac and runway vicinity air routes have been modelled as a graph. Real time constraints have brought us to develop an algorithm linear in complexity for the itinerary search problem. Operational pressure has led us to develop fast search strategies for scheduling (i.e. use of heuristics, hill climbing…).

Traces seven generations of Henri Fayol′s family through family records and public documents found in France. These previously unpublished records document the financial situation of the Fayol family, further details of Fayol′s career, and other information concerning his descendants. For many years the Fayol family members and their in‐laws had close ties with Commentry‐Fourchambault and Decazeville. Suggests the circumstances which led to the estrangement of Henri Fayol from his only son, as well as the role the Fayols played in the international management movement.
