Structure and Power in Multilateral Negotiations: An Application to French Water Policy

Stakeholder negotiation is an increasingly important policymaking tool. However, relatively little is understood about the relationship between the structure of the negotiating process and the effectiveness with which stakeholders can pursue their individual interests. We apply the Rausser- Simon multilateral bargaining model to a specific negotiation process involving water storage capacity and use in the upper Adour Basin in southwestern France. We focus on a coalition of three stakeholder groups with aligned but distinct interests. In addition to the standard indices of bargaining powerԴhe distribution of political weights (ܡccessݩ and players٠utilities if an agreement is not reached, our analysis identifies other less obvious sources of power. First, a coalition member may benefit when his access is reduced if the redistribution increases the access of another coalition member who has a more favorable ܳtrategic location.ݠSecond, the interests of the coalition as a whole will usually, but not always, be advanced if its members cede access to a pokesmanݠrepresenting their common interests. However, some members may be adversely affected. Third, restricting the extent to which coalition members can make proposals that further their own individual interests at the expense of other coalition members will usually, but not always, harm the coalition as a whole.water, bargaining, negotiations, Environmental Economics and Policy, Institutional and Behavioral Economics,

Structure and bargaining power in multilateral negotiations : Application to water management policies in France

Environmental policies are characterized by a growing emphasis on participation, devolution and negotiated decision making. Increasingly, centralized top down decision making systems are being replaced by new forms of local governance. In their strongest versions, these involve delegation of formal authority to local stakeholders who are expected to decide collectively upon the management rules of local common-pool resources. Devolution is particularly important in relation to the allocation and management of scarce water resources. Indeed the French water law of 1992 institutionalised the notion of [...].

Simulation des négociations et intercommunalité sur l’étang de Thau

Dans le processus de réattribution des compétences d’aménagement de l’espace et de gestion de l’environnement au sein des intercommunalités, les gestionnaires des territoires sont souvent confrontés à la question de l’organisation des instances de concertation. Cet article propose de développer un modèle de marchandage multilatéral couplé à une méthode de révélation des préférences des acteurs d’un territoire, fondée sur la théorie politiciens-électeurs et mobilisant une analyse économétrique de l’électorat communal. La simulation des compromis obtenus sous différentes structures de négociation (communes ou intercommunalités) permet de comparer la stabilité de ces accords et d’anticiper la déformation des solutions. Ces analyses, très pertinentes pour les démarches concertées de gestion de l’eau, sont illustrées pour le bassin versant de la lagune de Thau, sur lequel un Schéma d’aménagement et de gestion des eaux et un Schéma de cohérence territoriale sont simultanément négociés et portés par la même structure d’animation.Public policies have evolved towards greater devolution of land and urban planning decisions, as well as natural resource management, to local stakeholders and local communities. . However, local elected representatives are often left without much guidance on the way they should promote and organize the negotiations between the local councils concerned by a common agenda on these issues. This article develops a multilateral bargaining model to simulate the outcomes of the negotiations, for various structures of the negotiation. Local preferences for land and urban planning options are revealed through an econometric analysis of past choices made by elected city councils, based on a politician-voter model. The article illustrates the feasibility of this modelling approach by applying it to the case of the Thau laguna territory (South East of France)

Long-term follow-up of autologous stem cell transplantation after intensive chemotherapy in patients with myelodysplastic syndrome or secondary acute myeloid leukemia.

International audienceWe report on the outcomes of 53 patients with myelodysplastic syndromes (MDS) or acute myeloid leukemia secondary to MDS, autografted in first complete remission. Five (9.4%) died from the procedure whereas hematological reconstitution occurred in all the remaining patients. Forty patients (75%) relapsed, with 87.5% of the relapses occurring within 2 years of the autologous transplant. With a median follow-up of 6.2 years, the median actuarial disease-free survival and overall survival were 8 and 17 months after autograft, respectively. Karyotype was the only prognostic factor for disease-free and overall survival. The eight survivors (15%), including two patients with unfavorable or intermediate karyotype, remained in first complete remission 50+ to 119+ months after transplantation and are probably cured

Quelles connaissances du Plan S et de la stratégie de non-cession des droits ??

Cette enquête intitulée « Quelle·s connaissance·s du Plan S et de la stratégie de rétention [non-cession] des droits ? » a été menée à la fin de l’année 2022 par le groupe juridique du groupe de travail science ouverte du Consortium Couperin (GTSO). Diffusée sous forme d’un questionnaire en ligne, elle s’adressait aux professionnels de l’information scientifique et technique (IST) et personnels des services d’appui à la recherche, travaillant dans des universités, organismes de recherche et grandes écoles. L’objectif de cette enquête était de mesurer le niveau de connaissance et d’appropriation du Plan S de ces professionnels, leurs besoins éventuels d’accompagnement, alors qu’il n’existe pas à ce jour de cadre d’application global du Plan S dans les établissements et structures de recherche françaises

Inter-model comparison of sub-seasonal tropical variability in aquaplanet experimets: effect of a warm pool

This study compares the simulation of sub-seasonal tropical variability by a set of six state-of-the-art AGCMs in two experiments in aqua-planet configuration: a zonally-symmetric experiment, and an experiment with a warm pool centered on the equator. In all six models, the presence of the warm pool generates zonal asymmetries in the simulated mean states in the form of a “Gill-type” response, made more complex by feedbacks between moisture, convective heating and circulation. Noticeable differences appear from one model to another. Only half the models simulate mean low-level equatorial westerlies over the warm pool area. The presence of the warm pool can also favor the development of large-scale variability consistent with observed Madden-Julian Oscillation (MJO) characteristics, but this happens only in half the models. Our results do not support the idea that the presence of the warm pool and/or of mean low-level equatorial westerlies are sufficient conditions for MJO-like variability to arise in the models. Comparing spectral characteristics of the simulated Convectively Coupled Equatorial Waves (CCEWs) in the aquaplanet experiments and the corresponding coupled atmosphere-ocean (i.e. CMIP) and atmosphere-only (i.e. AMIP) simulations, we also show that there is more consistency for a given model across its configurations, than for a given configuration across the six models. Overall, our results confirm that the simulation of sub-seasonal variability by given model is significantly influenced by the parameterization of sub-grid physical processes (most-likely cloud processes), both directly and through modulation of the mean state

Genome sequence of the tsetse fly (Glossina morsitans):Vector of African trypanosomiasis

Tsetse flies are the sole vectors of human African trypanosomiasis throughout sub-Saharan Africa. Both sexes of adult tsetse feed exclusively on blood and contribute to disease transmission. Notable differences between tsetse and other disease vectors include obligate microbial symbioses, viviparous reproduction, and lactation. Here, we describe the sequence and annotation of the 366-megabase Glossina morsitans morsitans genome. Analysis of the genome and the 12,308 predicted protein-encoding genes led to multiple discoveries, including chromosomal integrations of bacterial (Wolbachia) genome sequences, a family of lactation-specific proteins, reduced complement of host pathogen recognition proteins, and reduced olfaction/chemosensory associated genes. These genome data provide a foundation for research into trypanosomiasis prevention and yield important insights with broad implications for multiple aspects of tsetse biology.IS
