Nonlinearities in the Becker-Tomes-Solon model
2011
The aim of this paper is to explore nonlinearities in the relationship between parents and children earnings. We rst discuss a simple extension of the Becker-Tomes-Solon model accounting for nonlinearity. We then test the linearity of intergenerational transmission employing a set of 141 intergenerational mobility tables in 35 di erent countries at di erent time periods, and nd that linearity is rejected in 89 tables. We nally explore the correlation between the \strength of concavity" and income inequality. Our ndings suggest that more unequal societies tend to have a more concave intergenerational transmission process.
La "società commerciale" e il tema della corruzione nel dibattito del XVIII secolo.
2018
La tradizione repubblicana, a partire da Machiavelli, pone la corruzione come l'elemento disgregatore della convivenza civile, la cui diffusione conduce al prevalere del vantaggio del singolo sul bene della comunità e alla perdita di libertà dei cittadini. La riflessione su virtù e corruzione nei secoli XVII e XVIII assume sempre più rilievo a seguito dell'affermarsi di una moderna economia di mercato e della transizione verso forme più avanzate di capitalismo. Tale dibattito giunge al suo più maturo compimento nel tardo illuminismo quando il tema della società commerciale - l'espressione con cui Adam Smith definisce quelle organizzazioni sociali fondate sul mercato- impone un ripensamento …
Sex and Sexuality
2021
Abstract Symbolic interactionist approaches to sexuality state that human beings become sexual as they become whatever else and learn sexual definitions and sexual meanings just like they learn any other kind of meaning. Therefore, interactionist analysis shifts the focus of inquiry into sex from being sexual towards becoming sexual, which takes into account how sexualities are produced, organized, and negotiated, rather than tracing their sources in an immutable (conception of) nature. Sociosexual meanings give people the chance to define themselves and others sexually, to construct their sexual self and doing sexual things together in the shaping of more complex sexual choreographies and …
Indications of a Si-rich bilateral jet of ejecta in the Vela SNR observed with XMM-Newton
2017
Context. The Vela supernova remnant displays several ejecta, which are fragment-like features protruding beyond the front of its primary blast shock wave. They appear to be "shrapnel", bowshock-shaped relics of the supernova explosion. One of these pieces of shrapnel (A), located in the northeastern edge of the remnant, is peculiar because its X-ray spectrum exhibits a high Si abundance, in contrast to the other observed ejecta fragments, which show enhanced O, Ne, and Mg abundances. Aims. In this Letter we present the analysis of another ejecta fragment located opposite to shrapnel A with respect to the center of the shell, in the southwestern boundary of the remnant, named shrapnel G. We …
Photonic fractional Fourier transformer with a single dispersive device
2013
In this work we used the temporal analog of spatial Fresnel diffraction to design a temporal fractional Fourier transformer with a single dispersive device, in this way avoiding the use of quadratic phase modulators. We demonstrate that a single dispersive passive device inherently provides the fractional Fourier transform of an incident optical pulse. The relationships linking the fractional Fourier transform order and scaling factor with the dispersion parameters are derived. We first provide some numerical results in order to prove the validity of our proposal, using a fiber Bragg grating as the dispersive device. Next, we experimentally demonstrate the feasibility of this proposal by us…
Travailler plus longtemps ? Enjeux professionnels et non-professionnels des départs à la retraite dans l'enseignement
2016
Au Québec, en raison du vieillissement de la population et de l’introduction, par le gouvernement, de politiques de maintien en emploi, les enseignants sont incités à travailler plus longtemps. Dans cet article, nous nous demandons si les enseignants peuvent être sensibles à ces incitations, et cherchons à en comprendre les raisons en analysant les conditions d’enseignement et les trajectoires de vie. La recherche s’appuie sur 24 entretiens semi-dirigés auprès d’enseignants âgés de 50 ans et plus, exerçant à différents niveaux dans les commissions scolaires francophones. Nous montrons que les enseignants rencontrés n’envisagent pas, pour la plupart, de prolonger leur service dans l’enseigne…
Société des Alcools du Québec : la gestion d’une nouvelle expérience client inspirée et inspirante
2017
International audience; Objectifs du cas et utilisation : Cette étude de cas s’adresse à des étudiants de premier cycle universitaire ou des professionnels en formation continue. Il s’intègre en tant que cas de synthèse ou cas fil rouge à des cours sur le marketing du commerce de détail, la gestion de l’expérience client, la communication et gestion de la relation client. Elle aborde les enjeux contemporains du commerce de détail, la gestion des mégadonnées, l’initiation aux outils de la méthode « Value Proposition Design » (Osterwalder et al., 2015), inspirée de la pensée Design (« Design Thinking ») ainsi que les concepts de marketing individualisé et marketing communautaire associés à l’…
Description, microhabitat selection and infection patterns of sealworm larvae (Pseudoterranova decipiens species complex, nematoda: ascaridoidea) in …
2013
Third-stage larvae of the Pseudoterranova decipiens species complex (also known as sealworms) have been reported in at least 40 marine fish species belonging to 21 families and 10 orders along the South American coast. Sealworms are a cause for concern because they can infect humans who consume raw or undercooked fish. However, despite their economic and zoonotic importance, morphological and molecular characterization of species of Pseudoterranova in South America is still scarce. Methods: A total of 542 individual fish from 20 species from the Patagonian coast of Argentina were examined for sealworms. The body cavity, the muscles, internal organs, and the mesenteries were examined to dete…
