Speciation of organic matter in natural waters. Interaction of polyacrylates with the major cation components of seawater
2004
The speciation of some high molecular weight polycarboxylates was studied in different ionic media. Polyacrylates here investigated (W=2.0, 5.1 and 20.0 kDa) form weak species with alkali metal cations (K=102 mol l1, t=25 jC, I=0 mol l1) and quite stable complexes with alkaline earth metal cations (K>106 mol l1, t=25 jC, I=0 mol l1). Results are reported from experiments performed in a multicomponent electrolyte solution simulating the major composition of seawater (artificial seawater). Protonation constants in this medium are expressed as a polynomial function of S1/2 (S=salinity) and the sharp lowering with respect to values obtained in non-interacting aqueous tetraalkylammonium salts ca…
Une formation pédagogique peut-elle modifier les conceptions de jeunes enseignants universitaires sur l’apprentissage et l’enseignement ?
2012
Nous analysons l’évolution des conceptions de l’apprentissage et de l’enseignement de jeunes enseignants universitaires à l’issue d’une formation en pédagogie universitaire, grâce à des informations de formations collectées lors de sessions de formation de l’Université de Bourgogne. Nous montrons que les conceptions à l’entrée et à la sortie de formation apparaissent variées et que celles-ci sont liées aux disciplines, à l’expérience et au projet professionnel. Les participants considèrent avoir changé de conceptions au terme de la formation. Ceux qui ont des visions nuancées et centrées d’emblée sur l’apprenant sont toutefois davantage influencés par la formation pédagogique.
La formazione dei genitori: un modello di intervento in contesti socioculturali "a rischio"
2013
This article presents a possible model of parents’ training in an area at risk by a socio-economic and cultural point of view. It clarifies the theoretical framework that, during four years, has been the basis for the design, the implementation and the evaluation of several actions in a primary school in the city of Palermo. From this theoretical framework, which concern primarily the eco-systemic and socioconstructivist perspectives, some basic points are enucleated, such as the concepts of "context" and of empowerment. Some methodological and operational choices are also explained, in line with this approach, such as: the dimension of the working group, the narrative and the life stories …
Increased conformational rigidity of humic substances by oxidative biomimetic catalysis
2005
A synthetic water-soluble meso-tetra(2,6-dichloro-3-sulfonatophenyl)porphyrinate of iron(III) chloride, Fe(TDCPPS)Cl, was employed as a biomimetic catalyst in the oxidative coupling of terrestrial humic materials. High-performance size-exclusion chromatography (HPSEC), solid-state nuclear magnetic resonance (CPMAS-(13)C NMR), electron paramagnetic resonance (EPR), and diffuse reflectance infrared spectroscopy (DRIFT) were used to follow conformational and structural changes brought about in different humic materials by the oxidative coupling. Increase in apparent weight-average molecular weight (Mw(a)) occurred invariably for all humic substances with the oxidative polymerization catalyzed …
Professionnalisation dans l'enseignement supérieur : quelles logiques territoriales ?
2009
En ligne sur : http://www.cereq.fr/index.php/content/download/562/8279/file/netdoc59.pdf; National audience; La question posée dans cette recherche est celle de l'existence d'une ou de plusieurs stratégies dans la construction de l'offre de formation professionnalisante dans l'enseignement supérieur ; la focale est placée sur l'étude des licences professionnelles, masters et doctorats. La construction de l'offre de formation y est abordée comme le résultat de coordinations complexes entre quatre catégories d'acteurs qui contribuent à cette construction : les organismes de formation, les entreprises, l'État et les collectivités territoriales.Les résultats de cette recherche reposent sur une …
Contact formation in random networks of elongated objects
2014
The effect of steric hindrance is an important aspect of granular packings as it gives rise to, e.g., limitations on the densities of ordered and disordered packings, both of which are essentially defined by the geometry of the constituents. Here we focus on random packing of rods via deposition and their distributions of contact number and segment length. Such statistical properties are relevant for mechanical properties of the structures, but the (quite large) steric effects on them have not been addressed in previous studies. We therefore develop a theory that describes the statistical properties of rod packings, while taking into account that the deposited rods cannot overlap and thus i…
Winter male plumage coloration correlates with breeding status in a cooperative breeding species
2007
The function of colored ornaments is usually related to the signaling of individual quality in intra- and intersexual interactions. In cooperative breeding species, where only a fraction of the male population access the breeding status and the other fraction has the option to help breeding pairs, colored traits might provide the females with a reliable information on the quality of potential mate. Males of the cooperative breeding azure-winged magpies (Cyanopica cyanus) display conspicuous blue plumage coloration. Here we explored the role played by structural blue coloration of males and the probability of becoming a breeder or a helper. Birds were trapped during 4 consecutive years, and …
Innovació en la manera d'avaluar de treballs en grup per motivar l'atenció dels alumnes
2014
En el nou escenari educatiu de l'Espai Europeu d'Educació Superior (EEES) cobra gran rellevància l'aprenentatge dels alumnes alhora que desenvolupen competències que els ajudin en el seu futur exercici professional. Entre aquestes habilitats es troben la capacitat de treball en equip i la capacitat d'exposar els resultats d'aquest treball d'una manera clara, concisa i rigorós. Per això el professor ha d'incentivar als alumnes a que es prenguin aquesta activitat amb la suficient motivació i fomentant la dedicació de la mateixa. Tradicionalment, l'exposició d'aquests treballs només interessava als propis membres del grup mentre que els seus companys veien aquesta activitat de forma passiva qu…
Corpo e movimento come arte della costruzione di Sé: Danza Movimento Terapia e formazione
2016
In this paper I present a training model for educators based on a DMT course at the University and I will explain the theoretical and methodological framework related to the educational goals. The aim is to give professional skills to be spent in educational and social fields thanks to the mobilization of creativity , the integration between the different parts of Self and the development of awareness and the "presence". At the same time, students, through the artistic experience centered on the body, enhance the competences (observational, communicative, interpersonal, etc) required for their job in the future . A DMT course activates, indeed, new stories and new existential perspectives i…
