Sur la base des travaux de Gérard Genette, en particulier Figures III, uneanalyse narratologique du roman L’Élégance du hérisson (2006) de l’auteur MurielBarbery a été effectuée afin de comprendre les liens qu’il y a entre les spécificités dumode narratif et leurs effets sur l’espace du récit, soit « le bocal à poissons », unemétaphore importante du roman. Ultimement nous répondons à la question suivante :En quoi la narration dans le roman L’Élégance du hérisson permet-elle de bien rendrela métaphore du « bocal à poissons »?

Ce mémoire est constitué par une analyse écocritique du roman Naissance d'un pont, écrit par Maylis de Kerangal. Le but général du mémoire est d'examiner comment ce roman décrit la relation entre l'homme et la nature. Nous examinons surtout les stratégies narratives employées par l'auteure pour transmettre l'image de cette relation et en plus, nous discutons le rôle joué par les différents paysages se retrouvant dans le récit. Finalement, l'analyse comprend aussi une brève réflexion sur la capacité éventuelle du roman d'influencer l'attitude du lecteur envers l'écologie. L'analyse des stratégies narratives se concentre sur le rôle du narrateur, ainsi que sur la présence et la fonction des perspectives éthiques, des noms symboliques et des figures de style. Ces stratégies contribuent à dépeindre une variété d'idées par rapport aux modes de vie de la société humaine, alors que les descriptions des paysages démontrent la relation complexe entre cette société et les paysages naturels et construits respectivement. Naissance d'un pont semble promouvoir une attitude à l'égard de la nature qui est plus humble que celle dominant dans la société moderne. Afin de pouvoir juger la capacité du roman de transmettre ces valeurs au lecteur, il serait pourtant raisonnable de tenir compte de plusieurs facteurs, tels que la complexité du langage et le niveau de crédibilité de l'histoire.

Arabidopsis thaliana ecotype Columbia-0 was transformed with a green fluorescent protein (GFP) gene under control of a phenylalanine ammonia-lyase (PAL) promoter. PAL is a key enzyme of the phenylpropanoid pathway and is induced to high levels during plant stress. Constitutive expression of PAL1 promoter-controlled GFP occurred in vascular tissues within stems, leaves and roots and in developing flowers. PAL1 promoter–GFP expression was examined in leaves of transgenic plants subjected to an abiotic elicitor, mechanical wounding or to inoculation with the pathogens Pseudomonas syringae pv. tomato or Peronospora parasitica. Wounding of leaves and treatment with an abiotic elicitor and compatible interactions produced low to moderate levels of GFP. However, in incompatible interactions there were high levels of GFP produced. In incompatible interactions, the intensity of GFP fluorescence was similar to that produced in transgenic plants expressing GFP driven by the CaMV promoter. The bright green fluorescence produced in live cells and tissues was readily visualised using conventional fluorescence microscopy and was quantified using spectroflourometry. This is the first report of the use of GFP as a reporter of defence gene activation against pathogens. It has several advantages over other reporter genes including real time analysis of gene expression and visualisation of defence gene activation in a non-invasive manner.

The contemporary debate about quality education for children with disabilities and impairments has continued to focus on mainstream schools, and, more recently, the emphasis on inclusion considers the reproduction of exclusionary practice within school structures. While the socio-cultural construction of disability is recognised as disabling, this paper argues that a constructive approach to policy implementation can be accomplished by drawing on 'insider' information constructed by teachers involved in inclusive practice.

Purpose – The purpose of this paper is to discuss the use of moral theory as a philosophical analytical framework for built environment organisations' ethical codes of practice. The identified moral theories under consideration are “deontology”, “consequentialism” and “virtue ethics”.

Design/methodology/approach – The paper uses a case study to examine the use of moral theory to explain the ethical codes of practice of built environment professional organisations. The chosen organisation is the Royal Institution of Chartered Surveyors (RICS). The approach for conducting the case study is through semi-structured interviews with experienced RICS members which gather views on the application of moral theory to explain the RICS ethical principles.

Findings – The case study revealed that there are mixed views on the use of moral theory to explain the RICS code of practice. The general view is that deontology is the most suitable theory to explain the fact that the work or process has been undertaken correctly. On the other hand, there is also a view amongst senior professionals that virtue ethics is most appropriate as it addresses the importance of both the correct “result” and the correct “process”.

Research limitations/implications – The paper uses a case study approach to examine the ethical code of one built environment professional organisation. This research does not therefore claim empirical generalisation but instead provides illustrations on the use of moral theory to explain the code of practice of a built environment professional organisation. The paper is based on a series of interviews. The findings should be understood as the aggregated opinions of the interviewees.

Originality/value – The paper makes an original contribution to existing literature on the theoretical analysis of codes of practice for built environment professional organisations. It describes research which is the first to use moral theory as a framework for analysing rules of conduct of built environment professional organisations.
