Le statuts y stématique du Genévrier oxycédre Junyperus oxycedrus L. (Cupressacées): une contribution d'ordre biochimique et biométrique

Dimensiosis des galbules et/ou teneur en prodelphinidine des aiguilles permettent trés généralement de déterminer les sous-espéces oxycedrus et macrocarpa, respectivement septentrionale-continentale et méridionale-insulaire, du Genévrier oxyeédre Juniperus oxycedrus L. Parcontre, la sous-espéce nord-africaine rufescens (en montagne) ne parah pas distinguable à ces titres de la sous-espéce type. Mais l’étude biochimique plus approfondie d’une (méta)population languedocienne montre l’existence d’un polymorphisme proanthocyanique indépendant de la taille des galbules. Les deux sous-espéces classiquement reconnues pourraient donc n’étre que les formes extremes, homozygotes pour le caractére chimique considéré, d’un méme génóme spécifique. Si les spécimens littoraux (Corse, Majorque, Maghreb) correspondent bien à la pleine expression (= prodelphinidine forte) de ce polymorphisme, certains échantillons «péri-littoraux» (Baléares et Languedoc) trahissent une introgression (actuelle ou ancienne) ayee appartion d’individus hétérozygotes, aux teneurs intermédiaires: des génes «macrocarpa» sont done bien presents au nord de la Méditerranée, méme si le phénoméne n’est pas morphologiquement décelable, et ne mérite pas d’étre formalisé en termes systématiques.

Place et rôle de Juniperus thurifera dans les structures de vegetation des Alpes du Sud

Les formations a genévrier thurifère des Alpes françcaises du sud, présentent un intérêt biogeographique et historique de première importance. Les auteurs étudient les structures de végétation que le genevrier organise dans les étages supraméditerranéen et montagnards.

Groupements arbustifs el mégaphorbiaies du haut Jura français. Quelques aspects particuliers

Tras las observaciones efectuadas durante la sesión de la Amical Internacional de Fitosociogía en la Jura franco-suiza, los autores exponen alganos datos complementarios sobre las comunidades megafórbicas jurasianas con Cicerbita alpina y Adenostyles alliaria y analizan desde un nuevo punto de vista, la comunidad arbustiva de Jun¡perus nana, Pinus uncinata, Sorbus chamaespilus, Laburnum alpinum.., que existen en los pisos subalpino y montano superior del Jura.

Social Work and theatre: considering intersections

Theatre is a cultural and artistic form that involves a process of communication between creators and is received in a space and time located in the public sphere, which has meant that, over the centuries, it has acted as a space for expression, exchange and debate regarding all manner of ideas, causes and struggles. Implicit within this process are processes of expression, creation and reception, by way of which people demonstrate, analyse and question ways of seeing and understanding life, and ways of being and existing in the world. This gives rise to educational, cultural, social and political potential, which has been endorsed in numerous studies and investigations. In this work, in which theoretical orientation is established through a review of the relevant literature, we consider different intersections that occur between theatre and social work in order to also show that dramatic and theatrical expression offers substantive methodologies for achieving some objectives of social work, particularly in areas such as critical literacy, reflexivity and recognition, awareness raising, social participation, personal and/or community development, ownership of cultural capital and access to personal and social wellbeing.

The Rhetorical Construction of Corporate Logos

This research is set in the context of today’s societies, in which the corporate visual symbology of a business, corporation or institution constitutes an essential way to transmit its corporate image. Traditional discursive procedures can be discovered in the development of these signs. The rhetorical strategies developed by the great classical authors appear in the logo-symbols expressing the corporate values of today’s companies. Thus, rhetoric is emerging once again in the sense it had many centuries ago: A repertory of rules that, paradoxically, standardizes the deviations of language and whose control is synonymous with power. The main objective of this study is to substantiate the rhetorical construction of logos using as a model of analysis the classical process of creating discourse. This involves understanding logos as persuasive discourses addressed to a modern audience. Our findings show that the rhetorical paradigm can be considered as a creative model for the con­struction of an original logo consistent with a company’s image.
