Collective management of environmental commons with multiple usages: a guaranteed viability approach
In this paper we address the collective management of environmental commons
with multiple usages in the framework of the mathematical viability theory. We
consider that the stakeholders can derive from the study of their own
socioeconomic problem the variables describing their different usages of the
commons and its evolution, and a representation of the desirable states for the
commons. We then consider the guaranteed viability kernel, subset of the set of
desirable states where it is possible to maintain the state of the commons even
when its evolution is represented by several conflicting models. This approach
is illustrated on a problem of lake eutrophication.Comment: 22 pages, 4 figure
Decision-making and negotiation assistant using viability analysis - An application to the participatory management of protected areas
La bonne gestion des espaces partagĂ©s impose de tenir compte de la multiplicitĂ© des parties prenantes qui ont chacune leurs valeurs et leurs objectifs. Elle est soumise Ă deux problĂšmes rĂ©currents. Le premier est lâabsence de consensus, le second est un consensus sur une solution inefficace dans sa rĂ©ponse aux problĂšmes soulevĂ©s. Combiner lâaspect participatif avec une aide technique permet dâaborder chacun des deux aspects. Il est possible Ă la fois dâaider les acteurs dans la prise de dĂ©cision, tout en aiguillant leur raisonnement vers un rĂ©sultat cohĂ©rent. Afin de fournir une aide technique, nous choisissons dâutiliser la thĂ©orie de la viabilitĂ© qui propose aux utilisateurs de dĂ©finir un ensemble de contraintes regroupant les intĂ©rĂȘts et objectifs de chacun. Cette mĂ©thode possĂšde deux avantages. Dâune part, il nâest plus nĂ©cessaire dâagrĂ©ger ou de hiĂ©rarchiser les critĂšres. Dâautre part, la viabilitĂ© permet la prise en compte dâun horizon temporel infini, impliquant le respect de lâĂ©quitĂ© intergĂ©nĂ©rationnelle. De plus, nous nous inspirons des techniques utilisĂ©es pour la conception de jeux sĂ©rieux afin de confĂ©rer un aspect Ă©ducatif et de sensibilisation Ă notre outil pour la gestion participative. Ce travail de thĂšse est axĂ© sur la conception, le dĂ©veloppement et lâĂ©tude de lâimpact dâun outil pour la gestion participative basĂ© sur la thĂ©orie de la viabilitĂ©. Nous avons implĂ©mentĂ© un prototype dâassistant informatique concrĂ©tisant les idĂ©es proposĂ©es dans la thĂšse. Puis, nous avons menĂ© une premiĂšre expĂ©rimentation de son utilisation afin dâanalyser son intĂ©rĂȘt et les avantages apportĂ©s Ă la dĂ©cision et Ă la nĂ©gociation. Cette Ă©valuation nous a permis dâĂ©tudier lâinfluence de cet outil sous lâangle de lâaide Ă dĂ©cision, de lâaide Ă la nĂ©gociation et de la sensibilisation aux enjeux soulevĂ©s par le partage des ressources. Une application inspirĂ©e du cas des rĂ©serves extractivistes brĂ©siliennes nous a permis dâillustrer cette dĂ©marche.Good management of shared spaces requires taking into account the multiplicity of stakeholders who each have their own values and objectives. It is subject to two recurring problems. The first is the lack of consensus, the second is a consensus on an ineffective solution in its response to the problems raised. Combining the participatory aspect with technical assistance makes it possible to address both aspects. It is possible both to help the actors in the decision-making process, while at the same time directing their reasoning towards a coherent result. In order to provide technical assistance, we choose to use the theory of viability, which proposes to users to define a set of constraints grouping the interests and objectives of each. This method has two advantages. On the one hand, it is no longer necessary to aggregate or prioritise the criteria. On the other hand, viability allows an infinite time horizon to be taken into account, implying respect for intergenerational equity. Moreover, we draw inspiration from the techniques used for the design of serious games in order to give an educational and awareness-raising aspect to our tool for participatory management. This thesis work focuses on the design, development and impact study of a tool for participatory management based on viability theory. We have implemented a prototype of an IT assistant that gives concrete form to the ideas proposed in the thesis. Then we conducted a first experimentation of its use in order to analyse its interest and the benefits brought to decision making and negotiation. This evaluation allowed us to assess the influence of this tool from the point of view of decision support, negotiation support and awareness of the issues raised by resource sharing. An application inspired by the case of Brazilian extractive reservation allowed us to illustrate this approach

The proportion of days with NRS †4/10 was greater in the acupuncture group than in the standard care group (61% vs 48%, p = 0.007). The mean Oswestry disability score was lower in the acupuncture group than with standard care alone (33 versus 38, Î = 5, 95% CI: 0.8 to 9, p = 0.02). Average total costs were higher in the control group (âŹ2947) than in the acupuncture group (âŹ2635, Î = ââŹ312, 95% CI: -966 to +325), resulting from the higher indirect costs of absenteeism and presenteeism. Acupuncture was a dominant strategy when both healthcare and non-healthcare costs were included. Costs for the health system (employer and out-of-pocket costs excluded) were slightly higher for acupuncture (âŹ1512 versus âŹ1452, Î = âŹ60, 95% CI: -272 to +470).</p><p>Conclusion</p><p>Acupuncture was a dominant strategy when accounting for employer costs.

Feasibility and efficacy of a supervised home-based physical exercise program for metastatic cancer patients receiving oral targeted therapy: study protocol for the phase II/III - UNICANCER SdS 01 QUALIOR trial
International audienceBackground: Currently, oral targeted therapies are known to be effective and are frequently used to treat metastatic cancer patients, but fatigue is a frequently reported early side effect of these treatments. This fatigue may impact the patientâs treatment adherence and result in a negative impact on quality of life. Physical exercise significantly improved the general well-being and quality of life of advanced cancer patients. However, there is no specific physical activity program adapted for patients with advanced disease. Methods QUALIOR is a two-part, randomized, open-label, and multicenter with two arms phase II/III trial. Patients (phase II: n =â120; phase III: n =â312) with metastatic cancer (breast cancer, kidney cancer, lung cancer, and other cancers [including but not limited to colon cancer, melanoma, sarcoma, or hepatocarcinoma]) treated with a first- or second-line oral targeted therapy without chemotherapy will be included. Patients will be randomized (2:1) to a 3-month supervised home-based standardized physical activity program or to a recommended adapted physical activity (via a booklet). The primary objective of the phase II is to evaluate the feasibility of the supervised program. The primary objective of the phase III is the evaluation of the benefit of the supervised home-based program compare to the recommended program in terms of fatigue and quality of life at 3âmonths. The secondary objectives aim to evaluate the impact of the supervised program on fatigue over time, pain, physical capacities, psychosocial and cognitive functions, general quality of life, frequency of dose reduction and patientsâ adherence to the targeted therapy, overall survival, and progression-free survival. This study will also evaluate the medico-economic impact of supervised program compared to the recommended adapted physical activity program. Discussion The aim of this study is to evaluate home-based physical exercise program for metastatic cancer patients treated with oral targeted therapies to help patients to cope with fatigue and improve quality of life. Trial registration This trial was registered in ClinicalTrials.gov since May 2017 ( NCT03169075 )
