Major cardiotonics are now widely used in reviving patients and we are concerned with shock following cardiac surgery. It is, however, difficult to use the most efficient of them, e.g. isoprenalin, with required accuracy regarding its effects. We describe a model which simulates the haemodynamic response to variable doses of cardiotonics. Firstly, one has to identify the parameters of this model and to test it on experimental data. Then one has to use the resulting model in the frame of optimal control of time‐dependent systems in order to determine some doses nearest the optimum.

Many bio‐medical models leads to differential systems. Some coefficients (exchange parameters,…) must be identified from partial observation on the system's solution. We suggest methods to study the existence and unicity of the identification problem. Applications to numerical identification are also given, in particular when unicity is not ensured. Physiological systems, like respiratory system, are concerned with the identification of parameters.

The trajectory of François Perroux across the Vichy regime poses about all possible range of methodological issues to the historian of ideas: individual versus collective biography, ideational versus ideological reading, internal versus external analysis, etc. The chapter outlines key elements about Perroux’s trajectory showing the entanglements and boundaries of science and politics in the transition from democratic to authoritarian rule and vice versa. A particular emphasis on uncertainties and adjustments shows, against the tendency to a teleological explanation induced by a linear interpretation of his career, that different paths were considered by Perroux, but that his choices were nevertheless constrained by the forces of both the scientific and political fields.

The chapter analyzes François Perroux’s institutional and intellectual activities under the Vichy regime (1940–1944) mainly by drawing on archival insights from Perroux’s papers. The authors argue that Perroux used his strategic position as general secretary of the Carrel Foundation (created by Marshal Pétain) to reshape French economics along a twofold trend: unifying economics with other social sciences, on the one hand; and developing its most analytical aspects, on the other hand. Thus, Perroux seized the opportunity to push for the introduction and dissemination of foreign theoretical studies within French economics, quite counter-intuitively to the expected nationalistic fallback accompanying authoritarian rule. In the end, the Vichy regime proved a suitable vehicle for the advancement of Perroux’s ideas and career: he managed in fact to make the best of a highly uncertain situation in 1940 and especially in 1944, with the impending Liberation of France. The authors show that Perroux used different strategies to neutralize those aspects of his work associated to Vichy’s ideology.

There is no one best way to teach management and organizational behaviour to MBA students; job demands force educators to consider multiple course objectives as well as multiple methodologies for achieving these objectives. Suggests desirable objectives or outcomes and then identifies instructional methods that are the most appropriate for achieving the various outcomes. A focus on managerial job demands resulted in the identification of six outcomes: content knowledge, self‐knowledge, diagnostic skill, application skills, teamwork skills and self control. These outcomes and 13 instructional methods are presented in a matrix showing which outcomes are impacted by the different methodologies. Implications for the implementation of this multi‐method approach are discussed.

Unlike many militaries in Europe, the Canadian Forces (CF) have no union or representative association. Although two separate studies have shown that more than one-third of military members think positively about forming a union (Bradley & Charbonneau, 2004; Deneumoustier, 1971), there has traditionally been little movement towards any form of associationism within Canada's military. While there is no formal ‘contract’ between the CF and the government of Canada, an informal social contract has appeared to be successful in maintaining the status quo. Critics of the social contract argue the agreement is one-sided; that is, the responsibilities of the member to Canada are well defined in the National Defence Act and Queen's Regulations and Orders but there is “no such articulation of the responsibilities of the Government of Canada to the men and women of the CF” (Milner, 1998, p. 10).

The archives of François Perroux deposited at IMEC bear witness to the fact that he has devoted, beyond his scientific production, great energy to the most material aspects of research: setting up and maintaining networks to publicize his work and that of other economists, either directly or through the institutes and the journals he headed; organize seminars and symposiums; take care of relations with colleagues and the press; create collections and journals; and so on.

In this chapter, we concentrate our attention on the archives relating to the management of the institutes, those attesting to the lines and themes of the producer’s research, and those concerning his important correspondence.

Thanks to the archives deposited at IMEC, it is possible to follow the development of the theoretical work of François Perroux by contextualizing it. They also show the itinerary of a Christian intellectual, whose attachment to social Catholicism constitutes a guiding thread and is reflected in all his activities. Finally, the archives illuminate his substantial role in the institutionalization of research in economics in the France of the twentieth century.

It is a huge technical and engineering challenge to realize the precise assembly of thousands of large optics in high power solid-state laser system. Using the 400-mm aperture-sized transport mirror as a case, this paper aims to present an intelligent numerical computation methodology for mounting performance analysis and modeling of large optics in a high-power laser system for inertial confinement fusion (ICF).

Fundamental principles of modeling and analysis of the transport mirror surface distortion are proposed, and a genetic algorithm-based computation framework is proposed to evaluate and optimize the assembly and mounting performance of large laser optics.

The stringent specifications of large ICF optics place very tight constraints upon the transport mirror’s assembly and mounts. The operational requirements on surface distortion [peak-to-valley and root mean square (RMS)] can be met as it is appropriately assembled by the close loop of assembly-inspection-optimization-fastening. In the end, the experimental study validates the reliability and effectiveness of the transport mirror mounting method.

In the assembly design and mounting performance evaluation of large laser optics, the whole study has the advantages of accurate evaluation and intelligent optimization on nano-level optical surface distortion, which provides a fundamental methodology for precise assembly and mounting of large ICF optics.

This paper assesses the impact of this program on the rural women's employment opportunities using data from the 2015 round of the household's living standard survey (HLSS) of Côte d'Ivoire.

In 2013, in order to improve the living conditions of the rural population, the Ivorian government launched the National Program for rural electrification (PRONER) to electrify all localities with more than 500 inhabitants.

The results show that PRONER, while reducing the time allocated to performing household chores, increases women's employment through the reallocation of time to full-time paid work in the agricultural and non-agricultural sectors. The authors also find that the allocation of men's time is not affected by this programme. A possible mechanism that would explain such a pro-women effect is the labour-saving technology introduced to home production as an effect of the reform.

As a limitation, it is important to note that these results were obtained in the specific context of PRONER in Côte d’Ivoire and are not necessarily applicable to rural electrification programmes in other contexts. Furthermore, the choice of other indicators to measure women's empowerment is limited by the quality of the data available. It would be interesting for future research to extend this analysis to include other aspects of women's empowerment and household welfare.

This paper is the first to the author’s knowledge to apply a robust econometric method by combining an inverse probability weighted regression adjustment model with Heckman sample selection method to access a robust causal effect of the PRONER in Côte d'Ivoire.
