Mesure de la performance globale dans une entreprise socialement responsable : une synthèse de la littérature
No full textL’évolution de la notion de la performance globale vient immédiatement lancer le débat sur la question de son évaluation. Cette évaluation « globale » sous-entend une multitude d’évaluations : évaluation économique et financière, évaluation sociale des compétences du personnel, évaluation des effets écologiques et environnementaux, évaluation des actes et opérations sociaux en matière de gestion publique, etc. La mesure de la performance globale consiste à produire systématiquement les indicateurs relatifs aux différentes dimensions de la RSE. Cette mesure globale constitue une transcription de la situation économique, sociale et environnementale en données statistiques chiffrées.
Nous allons essayer, à travers ce papier, de répondre à la question suivante : comment peut-on mesurer cette performance globale dans le cadre d’une entreprise socialement responsable ?
En d’autres termes, parmi les outils d’évaluation proposés dans la littérature, quels sont ceux qui sont à même de rendre compte d’un déploiement d’une démarche RSE par les entreprises
THREE ESSAYS ON INTERNATIONAL ASSET PRICING
No full textThe common thread running through my research is to explore the asset price dynamics across countries and across asset classes. In the first chapter of this thesis, I apply Newton's law of universal gravitation to investigate the determinants of the bilateral relationships in returns. Examining the gravity effect in a large set of countries, I find that the size of economies and geographical distance are significant determinants of the contemporaneous as well as the lead-lag correlation patterns observed in stock returns across countries. In addition, decomposing stock market returns into cash-flow and discount-rate news shows that the international transmission of country specific news is more pronounced through discount-rate news, and that the size of economies and geographical distance are significant determinants for both components of returns.
In the second chapter, based on a joint work with Redouane Elkamhi and Mikhail Simutin, we propose a diversification approach that exploits the global connectedness of developed countries to gain exposure to emerging countries' overall economies rather than their shallow equity markets. In doing so, we demonstrate that developed markets still offer substantial diversification benefits beyond those available through equity indices, contrary to a large body of literature claiming that the benefits of international diversification via developed markets have dramatically declined. Our results also suggest that relying on equity indices to assess diversification benefits understates diversification gains.
The third chapter explores the potential risk of investing in global markets. Specifically, my co-author Redouane Elkamhi and I study the two widely-known speculation strategies in the FX market, carry and momentum trades, and provide a risk-based explanation for the excess returns. We construct a common factor that drives correlation across international equity markets and show that the cross-sectional variations in the average excess returns across carry and momentum portfolios can be explained by different sensitivities to our correlation factor. By using a factor constructed from the equity market to explain abnormal return in the FX market, these findings shed light on the important linkage across the two markets through equity correlations as a main instrument of the aggregate risk.Ph.D

L’évaluation de la performance: Quels indicateurs pour le système de santé au Maroc ?
No full textThis article provides an assessment of the performance of the Moroccan healthcare system by outlining its current state and the methodology used to measure its performance. Based on key indicators and recent data, it highlights the structural and organizational challenges faced by the system, particularly regional disparities in access to care, shortages of human and material resources, as well as constraints related to funding and governance.The article also emphasizes the limitations of the current tools for measuring and monitoring healthcare performance, which complicates the identification of priority needs and the development of appropriate solutions. Furthermore, it highlights the need to improve transparency, strengthen data collection and analysis capabilities, and align performance indicators with international standards to facilitate comparisons and benefit from best practices. Drawing on successful experiences from other countries, the analysis proposes areas for improvement for Morocco, such as adopting an intersectoral approach, increasing the involvement of local stakeholders, and implementing more robust health information systems. These proposals aim to promote efficient and equitable resource management while meeting the population's expectations in terms of the quality and accessibility of care.L'évaluation de la performance des systèmes de santé est un élément essentiel pour pouvoir assurer une prestation efficace et équitable dans les prestations de soins de santé. Dans ce cadre, les indicateurs de performance jouent un rôle crucial en permettant de mesurer les résultats des politiques de santé et d'orienter les réformes nécessaires.Cet article se penche sur les indicateurs de performance appliqués au système de santé marocain et propose une étude comparative avec d'autres systèmes de santé internationaux. En s'appuyant sur des indicateurs clés et des données récentes, il met en lumière les défis structurels et organisationnels auxquels le système est confronté, notamment les disparités régionales dans l'accès aux soins, l'insuffisance des ressources humaines et matérielles, ainsi que les contraintes liées au financement et à la gouvernance. L'article souligne également les limites des outils actuels de mesure et de suivi des performances en santé, ce qui complique l’identification des besoins prioritaires et l’élaboration de solutions adaptées. Par ailleurs, il met en évidence la nécessité d'améliorer la transparence, de renforcer les capacités de collecte et d’analyse des données, et d’aligner les indicateurs de performance sur les normes internationales pour faciliter les comparaisons et bénéficier des meilleures pratiques. En s’inspirant des expériences réussies dans d’autres pays, l’analyse propose des pistes d’amélioration pour le Maroc, telles que l’adoption d’une approche intersectorielle, l’implication accrue des acteurs locaux, et la mise en place de systèmes d’information sanitaire plus robustes. Ces propositions visent à promouvoir une gestion efficace et équitable des ressources tout en répondant aux attentes des populations en matière de qualité et d’accessibilité des soins

La capacité d’apprentissage, comportement stratégique et performance : vers une lecture intégrative dans les coopératives artisanales
No full textCet article propose une lecture intégrative des liens entre apprentissage organisationnel, comportement stratégique et performance multidimensionnelle au sein des coopératives artisanales. À travers une revue systématique de la littérature (1990–2023) complétée par une analyse thématique exploratoire, il met en lumière les dynamiques d’apprentissage collectif qui permettent à ces structures hybrides de s’adapter à des environnements instables et de concilier viabilité économique, mission sociale et préservation des savoir-faire locaux. Le comportement stratégique y est envisagé comme un processus émergent, façonné par les pratiques, l’expérience et les ressources disponibles. La performance, quant à elle, est redéfinie selon une approche holistique intégrant des dimensions sociales, culturelles et territoriales, en cohérence avec les Objectifs de Développement Durable (ODD). L’article se conclut par la proposition d’un modèle conceptuel intégratif soulignant l’interdépendance dynamique entre ces trois dimensions, tout en appelant à une validation empirique dans des contextes émergents. Cette contribution vise à enrichir les cadres théoriques existants en intégrant les spécificités des organisations de l’économie sociale et solidaire
L’accompagnement entrepreneurial des coopératives : Le Marché Solidaire comme exemple de structure d’accompagnement au service des coopératives
No full textEntrepreneurial support, encompassing both financial and non-financial assistance, is a vector of growth and progression in emerging structures. This support has been extensively explored in management science research, generating substantial discourse. Nevertheless, the challenge persists in assessing its impact on the commercial performance of cooperatives. The correlation between financial and non-financial support and the commercial performance of cooperatives remains a focal point. While existing literature attempts to address this issue, the actual measurement of its tangible impact on business performance remains elusive. This article aims to conduct an analysis of the role played by the solidarity market as a support structure and platform for marketing products to benefit cooperatives.
Keywords : Cooperatives; Entrepreneurial support; Solidarity market; Support structures; Commercial performance.

Cet accompagnement a fait couler beaucoup d’encre dans les recherches en sciences de gestion. Pourtant, la problématique en relation avec l’évaluation de son impact sur la performance commerciale des coopératives reste encore posée. La question des liens entre L’accompagnement financier et non financier et la performance commerciale des coopératives reste à l’ordre du jour. Bien que la littérature propose des tentatives de réponses, nous avons toujours du mal à mesurer l’impact réel qu’il a sur la performance commerciale. L'objectif de cet article est de réaliser une analyse du rôle du marché solidaire en tant que structure d’accompagnement et plateforme de commercialisation des produits au profit des coopératives.

Temps et fonctionnement textuel chez Rachid Mimouni
No full textTime and Textual Functioning at Rachid Mimouni
The temporal dimension is a variable as important as space, and it is far from lacking in interest in the work of Rachid Mimouni. In fact, the issue of time considered as a structuring factor of the event representations which punctuate the story (1) is at the very heart of his romantic enterprise. To show how temporality exercises a locating and regulating function in the Mimounian text, we distinguish four temporal aspects to which the author focuses in his writing universe: romantic time, lived time, historical time and social time
Le marketing politique : comprendre sa démarche et son processus
No full textRésumé :
Le marketing politique est un processus d’action et de stratégies, ayant pour objectif de promouvoir un candidat, de favoriser son adéquation avec son électorat potentiel, et de développer sa notoriété auprès du plus grand nombre d’électeurs, tout en créant une différenciation avec les autres partis ou candidats, dans le but d’optimiser le nombre du suffrage obtenu, et gagner par la suite la campagne.
Plusieurs analystes de la scène politique limitent le phénomène du marketing politique uniquement à la communication publicitaire, alors que ce dernier ne constitue que la pointe de l’iceberg de la démarche marketing politique. En effet, la communication publicitaire s’avère un élément important, mais insuffisant au marketing politique, il constitue qu’un seul P de ses 4P (Produit, Prix, Promotion(communication) ; et Place). De ce fait, il est primordial de comprendre la démarche globale du marketing politique. Cette dernière englobe l’ensemble des étapes du processus marketing stratégique, opérationnel et tactique. Le marketing stratégique est mise en place, afin de faire les études de marché, et cela après avoir segmenter le marché , se positionner et cibler les segments ,tout cela dans le but d’analyser les besoins et comprendre les attentes des électeurs pour ensuite , concevoir l’offre politique qui satisfera au mieux les besoins de la cible ( électeurs) .Tandis que le marketing opérationnel et tactique est mise e place pour des actions à court terme, afin de gérer les imprévus et mettre en place les actions de la veille concurrentielle ( les autres partis politiques concurrents).Dans cet article on optera pour une typologie conceptuelle de notre revue de littérature, dans le but de repousser les limites traditionnelles de la littérature en marketing politique en mettant l'accent sur les idées, les concepts et le processus de la démarche marketing politique, plutôt que sur la narration linéaire ou les éléments esthétiques traditionnels du marketing politique .

Abstract :
Political marketing is a process of actions and strategies aimed at promoting a candidate, matching him to his potential electorate and developing his reputation with the greatest possible number of voters, while differentiating him from other parties or candidates, with the aim of optimizing the number of votes obtained, and subsequently winning the campaign.
Many analysts of the political scene limit the phenomenon of political marketing to advertising communications, when in fact the latter is only the tip of the iceberg of the political marketing approach. In fact, advertising communication is an important but insufficient element of political marketing, constituting just one of the 4Ps (Product, Price, Promotion (communication) and Place). For this reason, it is essential to understand the global approach to political marketing. This encompasses all stages of the strategic, operational and tactical marketing process. Strategic marketing is set up to conduct market research, after segmenting the market, positioning and targeting the party's target audience, with the aim of analyzing voters' needs and understanding their expectations, and then designing a political offering that best meets the needs of the target audience (voters), while operational and tactical marketing is set up for short-term actions, to manage unforeseen events and implement competitive intelligence actions (other competing political parties). In this article we will opt for a conceptual typology of our literature review, with the aim of pushing the traditional boundaries of political marketing literature by focusing on the ideas, concepts and process of the political marketing approach, rather than on linear narrative or the traditional aesthetic elements of political marketing.
Keywords: Political marketing, strategic political marketing, tactical political marketing, political segmentation, political positioning, political targeting, political mixed marketing

Efficiency of InN/InGaN/GaN Intermediate-Band Solar Cell under the Effects of Hydrostatic Pressure, In-Compositions, Built-in-Electric Field, Confinement, and Thickness
No full textThis paper presents a thorough numerical investigation focused on optimizing the efficiency of quantum-well intermediate-band solar cells (QW-IBSCs) based on III-nitride materials. The optimization strategy encompasses manipulating confinement potential energy, controlling hydrostatic pressure, adjusting compositions, and varying thickness. The built-in electric fields in (In, Ga)N alloys and heavy-hole levels are considered to enhance the results’ accuracy. The finite element method (FEM) and Python 3.8 are employed to numerically solve the Schrödinger equation within the effective mass theory framework. This study reveals that meticulous design can achieve a theoretical photovoltaic efficiency of quantum-well intermediate-band solar cells (QW-IBSCs) that surpasses the Shockley–Queisser limit. Moreover, reducing the thickness of the layers enhances the light-absorbing capacity and, therefore, contributes to efficiency improvement. Additionally, the shape of the confinement potential significantly influences the device’s performance. This work is critical for society, as it represents a significant advancement in sustainable energy solutions, holding the promise of enhancing both the efficiency and accessibility of solar power generation. Consequently, this research stands at the forefront of innovation, offering a tangible and impactful contribution toward a greener and more sustainable energy future.Dynamics of Micro and Nano System
