La dominance régionale et son imprécision : traitement dans le type général de structure
1978
Les notions d'influence et de dominance ont pour champ d'existence les structures d'échange, pas nécessairement économiques. Elles visent à mettre en évidence, par delà l'interdépendance, les relations de dépendance existant entre les éléments d'une structure. En économie, leur intérêt est essentiellement d'être un instrument pour le décideur. Elles lui permettent d'orienter la Politique Economique qu'il doit mener (relance, planification, restructuration, etc...) grâce à la détection des sous-ensembles stratégiques"de la structure .

Strength of J(pi)=1(+) Gamow-Teller and isovector spin monopole transitions in double-beta-decay triplets
2014
In this work we study systematically the energetics and intensity distributions of Gamow-Teller (GT ± )and isovector spin monopole (IVSM ± ) transitions from the ground states of the pairs ( 76 Ge, 76 Se), ( 82 Se, 82 Kr), ( 100 Mo, 100 Ru), ( 116 Cd, 116 Sn), ( 128 Te, 128 Xe), ( 130 Te, 130 Xe), and ( 136 Xe, 136 Ba), of double-beta-decay initial and final nuclei, to the J π = 1 + excited states of the intermediate odd-odd nuclei 76 As, 82 Br, 100 Tc, 116 In, 128 , 130 I, and 136 Cs. We use a proton-neutron quasiparticle random-phase approximation (QRPA) theory framework with the Bonn-A two-body interaction in large no-core single-particle valence bases. Our studies indicate that the GT −…
Loss of density-dependence and incomplete control by dominant breeders in a territorial species with density outbreaks
2011
Background: A territory as a prerequisite for breeding limits the maximum number of breeders in a given area, and thus lowers the proportion of breeders if population size increases. However, some territorially breeding animals can have dramatic density fluctuations and little is known about the change from density-dependent processes to density-independence of breeding during a population increase or an outbreak. We suggest that territoriality, breeding suppression and its break-down can be understood with an incomplete-control model, developed for social breeders and social suppression. Results: We studied density dependence in an arvicoline species, the bank vole, known as a territorial …
The adaptations to tube-dwelling life of Propsilocerus akamusi (Diptera: Chironomidae) larvae and its eutrophication-tolerant mechanisms
2019
Propsilocerus akamusi (Diptera: Chironomidae) is a dominant macroinvertebrate species in many eutrophic lakes in subtropical and temperate zones. P. akamusi larvae can migrate deep into the sediment (>30 cm) during summer where is no oxygen. However, to our knowledge, the specific adaptive tactics of its tube-dwelling life (>30 cm) and underlying mechanisms why this species is favored by nutrient-rich lakes remain limited. With the understanding above-mentioned issues, we can provide important information for the development of sensitive biomonitoring. We examined monthly morphological dynamics and physiological adaptations of P. akamusi to anoxic conditions, and environmental relationships…
Attitudes, Sentiments, and Concerns About Inclusive Education of Teachers and Teaching Students in Spain.
2020
The Sentiments, Attitudes, and Concerns About Inclusive Education Revised scale was developed to close the existing gap in measuring perceptions of inclusive education in the educative context. It has been widely used in other cultures but not in Spain. Our objective has been to analyze the psychometric properties in the Spanish sample by studying their relationship with empathy and social dominance variables, finally taking into account sociodemographic variables to observe if there are differences. The scale was applied to a total of 647 subjects: 323 university-students (18–45 years) and 324 in-service teachers (35–58 years). The scale showed psychometric properties suitable for the gene…
Fighting performance as a predictor of mating success in male black grouse
2010
As a consequence of certain conflicting evolutionary interests of males and females, the sexes have taken on different reproductive roles. In many species, where females invest more in the production of offspring, males compete for the opportunities to reproduce and females attempt to choose the highest quality males to sire their offspring. Males of different species signal their quality in a variety of ways, including physical cues such as color signals or exaggerated secondary sexual characters, behavioral signals and acquisition of a dominance status through aggression towards other males. In the lekking black grouse only a few males manage to copulate and active fighting is required fo…
Coherent conditional probabilities and proper scoring rules
2011
In this paper we study the relationship between the notion of coherence for conditional probability assessments on a family of conditional events and the notion of admissibility with respect to scoring rules. By extending a recent result given in literature for unconditional events, we prove, for any given strictly proper scoring rule s, the equivalence between the coherence of a conditional probability assessment and its admissibility with respect to s. In this paper we focus our analysis on the case of continuous bounded scoring rules. In this context a key role is also played by Bregman divergence and by a related theoretical aspect. Finally, we briefly illustrate a possible way of defin…
From Analysis to Formulation of Strategies for Farm Advisory Services (Case Study: Valencia – Spain). an Application through Swot and Qspm Matrix
2019
Abstract European agriculture should meet new increasing internal and contextual challenges. For example, the reform of the Common Agricultural Policy in 2003 introduced the cross-compliance, among other novelties, as compulsory for farmers. To better meet this and other requirements, Member States had to set up the so-called Farm Advisory System, operational across the European Union in 2007. From a sample of actors involved in the provision of farm advisory services in the region of Valencia (Spain), the present study aimed to identify the most appropriate strategies to implement such services. SWOT method has been applied to examine the internal and external environment. Based on this di…
L’économie de la santé : inégalités, prévention et offre de soins
2010
À partir d’une sélection des communications présentées lors des 31e Journées des économistes de la santé français à Rennes en décembre 2009, ce numéro spécial, coordonné par le Collège des Économistes de la Santé, présente des travaux originaux en économie de la santé. Comme à l’accoutumée, la revue Économie Publique - Public économies propose trois rubriques (« Panorama », « Dossier » et « Recherches »). Alain Trannoy (Ehess, Greqam-Idep) offre au lecteur tout d’abord un véritable « panorama...
