De la France vers l’Algérie : retours et contributions des femmes journalistes algériennes à travers la trajectoire de Keltoum Staali (années 1980)
No full textInternational audienceKeltoum Staali was one of the top name of the Algerian weekly Révolution Africaine during the 1980s. Writing in the society section, she covered topics such as youth, education, labor mobilization and broader social issues. Hired in the mid-1980s by the newspaper owned by the Front de libération nationale (FLN) party, she spent three years working within a dynamic editorial team. Born in France in 1960, to a working-class immigrant family, Keltoum Staali returned to Algeria after completing her university studies. In Algiers, she embarked on a career in journalism. Focusing on Staali’s personal and professional trajectory, this paper aims to contribute to the under-documented history of the media in post-independance Algeria, particularly the role of women journalists in the context of socialist Algeria. It draws on interviews conducted with Keltoum Staali since 2021, as well as her personal archives, published writings, and Algerian press archives from the 1980s. Through her life and professionnal experience, this study offers a portrait of a little-known generation of Algerian journalists raised in France who played a significant role in shaping the Algerian press
Redesign adaptatif des paysages urbains industriels. Le cas d'étude de la place de TEE à Komotini, Grèce
No full textInternational audienceDeindustrialization has left many industrial buildings inactive, raising questions about their role in contemporary urban life. This article explores how semiotics and psychogeography can reframe such structures as dynamic architectural happenings, shifting emphasis from preservation toward social value and collective experience. This research focuses on Komotini, Greece, where the Technical Chamber Square is reinterpreted through references to the adjacent Tobacco Warehouse. By integrating architectural traces of the past into new recreational and sporting functions, this study demonstrates how heritage can be embedded into everyday practices. Methodologically, this research employs qualitative approaches, including demographic and historical analysis of Komotini's urban and industrial development, alongside psychogeographic drifting walks. Twenty interviews were conducted with local business owners, residents, and visitors, as well as psychogeographic walks, generating insights into how communities interact with industrial heritage. The findings indicate that semiotics and psychogeography are effective tools for activating public spaces near former industrial sites, enabling the built environment to be understood as a layered record of successive interventions. The study concludes that adaptive redesign offers designers a methodology that can embed industrial fragments into vibrant public realms that sustain diverse communities, catalyze local economies, and honor historical identity through lived practices
Numerical Analysis of Test Optimality
No full textIn nonstandard testing environments, researchers often derive ad hoc tests with correct (asymptotic) size, but their optimality properties are typically unknown a priori and difficult to assess. This paper develops a numerical framework for determining whether an ad hoc test is effectively optimal-approximately maximizing a weighted average power criterion for some weights over the alternative and attaining a power envelope generated by a single weighted average power-maximizing test. Our approach uses nested optimization algorithms to approximate the weight function that makes an ad hoc test's weighted average power as close as possible to that of a true weighted average power-maximizing test, and we show the surprising result that the rejection probabilities corresponding to the latter form an approximate power envelope for the former. We provide convergence guarantees, discuss practical implementation and apply the method to the weak-instrument-robust conditional likelihood ratio test and a recently-proposed test for when a nuisance parameter may be on or near its boundary
Optimizing the Viability of Interacting Systems with Evolutionary Algorithms
No full textInternational audienceViability theory studies the behavior of dynamical systems, with the aim of keeping them viable, or in other terms, keep their trajectories within desired constraints in the state space. Finding strategies to keep a dynamical system viable is already a challenge for optimization algorithms, but this task becomes even harder for multi-agent systems, where agents’ individual decision can influence the dynamics of the whole system. In this paper, we consider a multi-agent dynamic system and introduce an evolutionary approach for optimizing agents’ interaction behaviour, delimited by some a priori agreements, in the form of a set of commitments, with the objective of keeping the system viable. This approach is tested on the case-study of a collective project grouping several agritouristic activities on a shared place. Experimental results show that it is possible to find a set of agents’ commitments that can maintain system viability, supporting the proposed framework’s effectiveness
The Need for Transformative and Equitable Health Policy
No full textInternational audienceAbstract COVID-19 has led to a sharp deterioration in livelihoods in Africa and plunged many people into extreme poverty, increasing the number of people excluded from health services. This situation is exacerbated by security issues in regions such as the Sahel, which weaken health budgets in favour of security budgets. Countries in the Sahel have health systems that struggle to provide their populations with the health services they need. The most disadvantaged groups are excluded from healthcare. The COVID-19 pandemic has exposed the fragility of social protection systems and reaffirmed the challenges facing health systems, as well as the need for equitable and transformative implementation of health policies. This means that health services and models must include the poor and their specific needs and provide an opportunity for multisectoral engagement so that health is a cross-cutting issue that should be addressed in other areas of the lives of the poor beyond the health system. Using the COVID-19 crisis as a starting point, this chapter uses comparative analysis to examine fundamental health policy issues in general and those affecting the poor in particular, based on the cases of four countries: Burkina Faso, Benin, Mali, Niger, and Senegal
Dynamic network formation with farsighted players and limited capacities
No full textInternational audienceWe investigate a T-stage dynamic network formation game with linear-quadratic payoffs. Players interact through network which they create as a result of their actions. We study two versions of the dynamic game and provide the equilibrium analysis. First, we assume that players sequentially propose links to others with whom they want to connect and choose the levels of contribution for their links. The players have limited total contributions or capacities for forming links at every stage which can differ among players and over time. They cannot delete links, but the principle of natural elimination of links with no contribution is adopted. Next, we assume that the players simultaneously and independently propose links to other players and have overall limited capacities for the whole game, and not for each stage. This means that every player can redistribute the capacity not only over links, but also over time. The equilibrium concept for the first version of the dynamic game is subgame perfect equilibrium, while it is the Nash equilibrium in open-loop strategies for the second version. Both models are illustrated with numerical examples
