Fresh Pod Yield, Physical and Nutritional Quality Attributes of Common Bean as Influenced by Conventional or Organic Farming Practices
2022
The aim of the current study wat to comparatively assess the impact of different nitrogen (N) fertilization schemes on fresh pod yield and yield quality in either organically or conventionally grown common beans (Phaseolus vulgaris L.). Prior to common bean crop establishment, the experimental field site was cultivated following either organic (a) or conventional (b) farming practices with a winter non-legume crop (Brassica oleracea var. italica) (BR), or (c) with field bean (Vicia faba sp.) destined to serve as a green manure (GM) crop. At the end of the winter cultivation period the broccoli crop residues (BR) and green manure biomass (GM) were incorporated into the soil and the plots tha…
Multiplicity in financial equilibrium with portfolio constrains under the generalized logarithmic utility model
2012
Previous research on the effects of constraints to take unbounded positions in risky financial assets shows that, under the logarithmic utility function, multiplicity of equilibrium may emerge. This paper shows that this result is robust to either constant, decreasing or increasing relative risk aversion obtained under the generalized logarithmic utility function.
La vulgarisation scientifique et les doctorants : mesure de l'engagement, exploration d'effets sur le chercheur
2018
We ask two questions: what are the factors that influence researchers’ public engagement activities (PEA)? And what are the impacts of these activities on the researcher? After presenting a historical overview of PEA, we analyze 20 surveys carried out between 1967 and 2014. We identify some global trends: PEA is generally positively perceived, researcher’s engagement is occasional but robust. Besides those trends some differences appear between studies based on theoretical models and empirical studies: the latter report complaints such as lack of time or lack of recognition, whereas theoretical-based ones challenge these statements.To further explore our two questions, we used two approache…
L'impact des services de vulgarisation agricole : revue de la littérature
1981
Référence interne : 81006; Cette étude est une tentative de synthèse de la littérature mondiale sur l'impact des services de vulgarisation agricole. Elle montre que les évaluations de l'efficacité interne des services de vulgarisation sont en général critiques : les services de vulgarisation sont présentés comme peu efficaces ; ils ne touchent qu'une minorité d'agriculteurs (ceux qui sont déjà les mieux dotés) ; ils poursuivent de mauvais objectifs et ne sont que de peu d'utilité pour promouvoir le développement rural.L'auteur souligne que ces diagnostics tendent à être excessifs, exagérément pessimistes, et que leurs auteurs n'ont pas toujours des critères d'évaluation appropriés. De plus,…
Platone e gli Eleati (II)
2017
Si cerca di mostrare che le tendenze eleatiche erano molto diffuse nell´ Atene del IV secolo, probabilmente nella stessa Accademia e che Platone ha scritto Sofista e Parmenide essenzialmente contro i Megarici Plato gives two constrasting accounts of Zeno's philosophical purposes in the Phaedrus and Parmenides. The Parmenides is more accurate in detail, and consequently it is more probable that Zeno intended to defend Parmenides' teaching, as he is represented as doing in this dialogue, than to accumulate eristic contradictions for their own sake, as he is represented as doing in the Phaedrus. Plato seems to be aware that one of the main features of Socratism, dialectic reasoning, originates…
Electrophoresis of model colloidal spheres in low salt aqueous suspension
2004
We report on comprehensive measurements of the electrophoretic mobility μ of a highly charged spherical colloid in deionized or low salt aqueous suspensions, where fluid and crystalline order develops with increased packing fraction Φ. We propose the existence of a 'universal' shape of the μ(Φ) showing three distinct regimes: a logarithmic increase, a plateau and a logarithmic decrease. The position and the height of the plateau are found to be influenced by the particle surface properties and the electrolyte concentration. In particular, it starts once the counter-ion concentration becomes equal to the concentration of background electrolyte. This coincides only loosely with the range of Φ…
