Jeu de Taquin and Diamond Cone for so(2n+1, C)
2020
International audience; The diamond cone is a combinatorial description for a basis of a natural indecomposable n-module, where n is the nilpotent factor of a complex semisimple Lie algebra g. After N. J. Wildberger who introduced this notion, this description was achieved for g = sl(n) , the rank 2 semisimple Lie algebras and g = sp (2n).In this work, we generalize these constructions to the Lie algebra g = so(2n + 1). The orthogonal semistandard Young tableaux were defined by M. Kashiwara and T. Nakashima, they index a basis for the shape algebra of so(2n + 1). Defining the notion of orthogonal quasistandard Young tableaux, we prove that these tableaux describe a basis for a quotient of t…
Chemical and isotopic characterization of rainwater in volcanic, urban and industrial areas of Sicily (Italy)
2021
The chemical composition of rainwater depends on (i) the dissolution of gases and particulate matter emitted by different sources, (ii) the chemical and physical reactions occurring during local and regional scale transport, and (iii) removal processes. The source of major and trace elements dissolved in rainwater can be both natural (e.g. sea salts, volcanic emissions, geogenic dust, biogenic material) and anthropogenic (e.g. industrial plants, vehicular traffic, domestic heating, vessel traffic). A group of trace elements has been recently brought to attention, especially for their possible environmental impacts, the Technology-critical elements (TCEs): Ga, Ge, In, Te, Nb, Ta, Tl, the Pla…
Calculating cohomology groups of $overline M_0,n(mathbb P^r,d)$
2003
Here we investigate the rational cohomology of the moduli space ℳ̄0,n (ℙr,d) of degree d stable maps from n-pointed rational curves to ℙr. We obtain partial results for small values of d with an inductive method inspired by a paper of Enrico Arbarello and Maurizio Cornalba.
Growth and population structure of perch in relation to diet in a small humic lake, Valkea-Kotinen
2011
Lake Valkea-Kotinen is a long-term ecological monitoring site in the Evo region of southern Finland .The aim of this study was to investigate the growth and population structure of perch (Perca fluviatilis L.) in relation to diet in Valkea-Kotinen in order to provide reference data for a study investigating effects of increased loading of dissolved organic matter to nearby Lake Alinen Mustajärvi. Valkea-Kotinen was predominantly inhabited by small benthivorous perch. The growth relationship between opercular bone and total length of perch in the lake is similar to those earlier analysed for nearby lakes. Compared to wider growth rates, the growth of perch was slow and similar to those in si…
El efecto del liderazgo auténtico y el tipo de establecimiento de metas sobre el desempeño y las respuestas actitudinales y afectivas de los seguidor…
2014
El papel que, en los últimos años, han jugado los líderes de organizaciones, tanto públicas como privadas, en el creciente número de escándalos que han sacudido la opinión pública internacional ha evidenciado la necesidad de un nuevo enfoque en el proceso de liderazgo. En este contexto, el liderazgo auténtico emerge como una alternativa post-heroica y post-autoritaria a los modelos de liderazgo basados en el carisma A pesar de que la investigación en liderazgo auténtico crece diariamente, aún es necesario explorar qué factores contextuales afectan a la influencia del líder auténtico sobre sus seguidores. En este contexto, el objetivo general de esta tesis es contribuir a la investigación so…
Scientific writing for impact factor journals
2013
EASARCICAPLivre dispo. dans :hal-00832739, version 1; Publish or Perish. This old adage illustrates the importance of scientific communication; essential to research, it also represents a strategic sector for each country’s competitiveness. An often-neglected topic, scientific communication is of vital importance, with new information technologies accelerating and profoundly changing how knowledge is disseminated. The necessity of optimally disseminating experts’ findings has also become crucial to researchers, institutes and universities alike, which has prompted the recent advent of Impact Factors for the evaluation and financing of research, the goal being for scientific knowledge to be …
L'articulation des indicateurs environnementaux entre contrôle diagnostique et contrôle interactif. Le cas d'une entreprise française de vins et spir…
2011
Cahiers de Recherche du FARGO - LEG, Université de Bourgogne; Depuis la Loi NRE, les entreprises cotées sur un marché réglementé français ont pour obligation de publier des informations sur les impacts environnementaux et sociaux de leurs activités. L'utilisation d'un système de contrôle de gestion, en particulier des indicateurs environnementaux, contribue au pilotage et au reporting de la performance de ces entreprises. Selon Simons (1995), ce système peut être utilisé soit de manière diagnostique pour atteindre les objectifs assignés, soit de manière interactive pour stimuler l'apprentissage organisationnel et l'émergence de nouvelles stratégies. Par contre, à notre connaissance, aucune …

Lake size and fish diversity determine resource use and trophic position of a top predator in high-latitude lakes
2015
Prey preference of top predators and energy flow across habitat boundaries are of fundamental importance for structure and function of aquatic and terrestrial ecosystems, as they may have strong effects on production, species diversity, and food-web stability. In lakes, littoral and pelagic food-web compartments are typically coupled and controlled by generalist fish top predators. However, the extent and determinants of such coupling remains a topical area of ecological research and is largely unknown in oligotrophic high-latitude lakes. We analyzed food-web structure and resource use by a generalist top predator, the Arctic charr Salvelinus alpinus (L.), in 17 oligotrophic subarctic lakes…
