Pre- and syn-eruptive geochemistry of volcanic gases from Soufriere Hills of Montserrat, West Indies
1998
International audience; Soufriere Hills fumaroles contained magmaderived volatiles before and during the eruption initiated in 1995 but also preserved a typical and quite steady hydrothermal coinposition. Chemical changes due to increased boiling and a greater input of oxidizing magmatic gas occurred only at Galway's Soufriere, the most active fumarolic field. Hydrothermal buffering of the fumaroles has been favoured by their remote location (!-2 km) froin the eruptive vents and by a preferential degassing of the uprising magma through intrusive conduits under the crater. High temperature (720øC) gas collected froin the extruding lava dome in Feb. 1996 was chemically and isotopically repres…
Could male tergal secretions be considered as a nuptial gift in the Madeira cockroach?
2008
International audience; Many male insects provide somatic nuptial gifts that may strongly influence reproductive fitness, ensuring effective copulation or mediating paternal resource benefits in offspring. Although the courtship feeding behaviour on tergal gland secretions has been described in numerous cockroaches, studies on the function of these so-called nuptial gifts are lacking in this group. In this study, we examined, in the Madeira cockroach, Leucophaea maderae, the functional significance of tergal secretions by manipulating their availability on the back of males. We tested whether male tergal secretions function as a form of mating effort, and/or as a form of paternal investment…
Gifted Education in German-Speaking Countries
2011
AbstractThe purpose of this article is to provide the reader with a comprehensive yet detailed account of the current giftedness and gifted education situation in Austria, Germany, and Switzerland. It is concerned with four main research questions: (1) How is ‘giftedness’ defined in German-speaking countries? (2) How are gifted children identified? (3) What gifted education programs are there? (4) What are the empirical findings on these programs?The article is based on relevant journal articles, books, and webpages. The review of each of the topics mentioned above is accompanied by some critical comments.
Cíborgs : res ipsa loquitur
2020
En el presente trabajo analizamos el daño desproporcionado sobre la naturaleza humana causado por el fenómeno cíborg a través de su encaje en la regla res ipsa loquitur, o la cosa habla por sí sola. Por un lado, fundamentamos lo que denominados naturaleza humana haciendo referencia a las iguales capacidades humanas, necesarias en el cumplimiento de funciones vitales. Por otro, esta regla recibe también el nombre de daño desproporcionado y su teoría vincula el resultado causado sobre la cosa con la lex artis de una profesión, de ahí que, para su análisis jurídico, hayamos optado por el ámbito sanitario
Protection of the surviving spouse in French law
2021
While French inheritance law has recently sought to give everyone more freedom to anticipate the transmission of their estate, it still guarantees to the children a reserved portion in his estate. This guarantees the deceased?s children a minimum share in his/her estate. However, the mechanisms protecting this reserve are subject to legal adjustments when spouses wish to organize the protection of the couple?s survivor, either by submitting to a conventional matrimonial regime or by giving themselves gifts that improve the legal succession of the spouse. This ensures a balance between the protection of the spouse and that of the compulsory heirs. Not seeming to be satisfied, several famous …
Ricerche in tema di società questuarie
2019
Intorno al regime delle società di tipo questuario – riconducibili agli schemi teorici della societas universorum quae ex quaestu veniunt – e delle società unius alicuius negotiationis e unius rei, si profusero gli sforzi interpretativi dei giuristi romani, fin dalla fine dell’età repubblicana. La monografia scientifica ripercorre le tracce della individuazione della nozione stessa di quaestus (guadagno), con particolare riferimento alla inclusione al suo interno delle donazioni cd. remuneratorie; ancora, ricostruisce il dibattito giurisprudenziale sorto intorno alla questione se i soci – nella determinazione delle quote – dovessero rispettare una proporzione rispetto ai conferimenti, con u…
Strategies exhibited by good and average solvers of geometric pattern problems as source of traits of mathematical giftedness in grades 4-6
2019
International audience; We describe and analyse the strategies used by students in primary grades 4, 5 and 6 to solve linear and affine geometric pattern problems. Based on two problems posed in a teaching experiment, we have identified several profiles of strategies used by students to solve the problems. We consider the profiles of students who were good geometric pattern problem solvers as traits that may help identify mathematical giftedness. Our results show that average students used very often incorrect functional strategies and were consistent in using incorrect proportional strategies along the grades. On the other hand, good geometric pattern problem solvers tended to use correct …
When are vomiting males attractive? Sexual selection on condition-dependent nuptial feeding in Drosophila subobscura
2009
Nuptial gifts are any nutritious items or inedible tokens transferred from the male to the female as a part of courtship or copulation. Although nuptial gift donation has been studied in a variety of taxa, this behavior has been largely overlooked in Drosophila. We studied nuptial feeding in Drosophila subobscura, where the gift is a regurgitated drop of liquid, in order to examine the importance of this behavior for male mating success and female fecundity. We varied male and female condition by dietary restriction to assess any condition dependence of male nuptial feeding ability and female feeding behavior and mate discrimination. Our results show that there was directional selection for…
Ethique professionnelle et régulation économique du marché des soins ambulatoires : de la théorie des contrats à l'économie des conventions
1992
What is the part played by professionnal ethics in the economic regulation of the market for ambulatory care (heterogeneity, uncertainty, information asymmetry...) and extrinsic rigidities (imposed by medical corporation and public authorities) ? Is it the internal control variable from "interested" self-regulation that implicitly relies on teological conception of ethics ? Or, the essential being of conventions for "quality" and "activity" that, through the cycle of gift economics, set upspontaneous order, with respect to professional ethics ? What usecan we do with such theoritical approach for the understanding andthe trend of politics in ambulatory care ?
Doni funesti. Miti di scambi pericolosi nella letteratura latina
2018
«I doni sono come gli ami» avverte Marziale. «Catturano anche gli dèi» afferma Ovidio. «Sono l’inganno in cui di solito incappano i re» osserva Seneca. La forza calamitante del dono, la sua natura seducente e pericolosa, emerge con chiarezza dall’analisi del sapere mitico romano e delle sue riscritture letterarie. I Romani, del resto, conoscevano bene il potere attrattivo dei doni, la loro capacità di condizionare i comportamenti e le dinamiche di relazione. Erifile è soggiogata dalla collana di Armonia, Mida è accecato dalla sua fame d’oro, Creusa è ingannata dai doni nuziali; Didone brucia con sé quelli dell’amato, Semele e Fetonte ne saranno bruciati. Il dono promesso è un rischio, il do…
