Influence of anthropogenic activity on the lead isotope signature of Thau Lake sediments (southern France): origin and temporal evolution
2000
Lead concentrations and isotopic compositions were determined on both bulk sediments deposited in the Thau lake in southern France during the last 200 years, and leachates derived from a series of sequential leachings of the sediments, making it possible to identify the sources, natural (i.e. indigenous lithologic) or anthropogenic, and to quantify the different inputs of Pb. Two distinct inputs of Pb could be distinguished. One of these corresponds to the terrigenous material entering the basin, representative of the local natural Pb ‘background’. Its supply remained steady most of the time with 206Pb/207Pb ratios of 1.200±0.003, except at the time of heavy storms producing voluminous and …
Collectivités et prestataires de services : enquête exploratoire pour la collecte des déchets ménagers
2006
Private management of local waste has been scarcely studied although this question shows an original technico-institutionnal pattern in the field of local urban management. Under the rule of the “Code des marchés publics”, arrangements are made on a pluriannual basis. Such a legal framework is supposed to imply competitive procedure and thus to strengthen the decision making process of local authorities. Yet, the actual control of public authorities over this relationship is put under question. This article – based on a number of empirical studies — deals with this matter. It reveals what is at stake by studying closely the actual process of a contract between a local authority and a firm.
L’expérience du consommateur dans le commerce de détail. Une revue de littérature
2013
Résumé Le thème de l’expérience s’est constitué en objet de recherche en marketing, grâce aux efforts investis par de nombreux distributeurs dans la création d’offres expérientielles. La littérature académique s’est d’abord concentrée sur les antécédents, la recherche et les conséquences de l’expérience, avant de prendre en compte le contenu même de l’expérience. Les stratégies des détaillants peuvent être analysées en mobilisant des grilles de lecture fondées sur la nature de la participation du consommateur à la production de l’expérience, ou sur le caractère extraordinaire ou ordinaire de l’expérience proposée. Le modèle synthétique proposé permet de rendre compte de l’expérience du con…
Comprendre les courses ordinaires : Enjeux et implications pour les grandes surfaces alimentaires
2010
This article aims at registering the common shopping within the framework of the domestic life, like housework. This different perspective allows a better understanding of this behaviour of purchase. Retailers will find in this paper some ideas to improve the customers' satisfaction during the ordinary and regular shopping they do.
La place de l’enseigne dans les trajectoires d’achat des clients en contexte multi-canaux
2014
International audience; Alors que les analyses des comportements dans un environnement multi-canaux adoptent généralement une dichotomie magasin – Internet, cet article s’interroge sur les conséquences de la multiplication des formes d’interactions réelles et virtuelles sur les processus de décision et d’achat. Il propose de retenir la notion de trajectoire de fréquentation, et d’analyser la place de l’enseigne dans ces comportements. Les résultats d’une étude quantitative menée auprès de 750 personnes pour plusieurs catégories de produits montrent que les individus adoptant un comportement multi-canaux ont tendance à adopter plus souvent un comportement multi-enseignes (fréquenter plusieur…
Diferencias cross-culturales en la decisión de compra de los jóvenes europeos
2010
El presente trabajo se ha planteado en torno a dos objetivos principales. Por un lado, investigar los antecedentes en la decisión de compra de los jóvenes consumidores europeos de cuatro países. Por otro, analizar cómo varía la influencia de estos antecedentes cuando se consideran consumidores de distinta nacionalidad y distintas categorías de productos. Para desarrollar este estudio se procedió a encuestar on line a una 'muestra de conveniencia'. Para ello, se contó con la colaboración de cinco universidades que tomaron parte en esta red: una de Francia, una de Alemania, una de Italia y dos de España. De este modo, se obtuvo una muestra final de 295 jóvenes. Los resultados exhiben que los …
Co-treatment of landfill leachate in laboratory-scale sequencing batch reactors: analysis of system performance and biomass activity by means of resp…
2014
Aged or mature leachate, produced by old landfills, can be very refractory; for this reason mature leachate is difficult to treat alone, but it can be co-treated with sewage or domestic wastewater. The aim of the study was to investigate the feasibility of leachate co-treatment with synthetic wastewater, in terms of process performance and biomass activity, by means of respirometric techniques. Two sequencing batch reactors (SBRs), named SBR1 and SBR2, were fed with synthetic wastewater and two different percentages of landfill leachate (respectively 10% and 50% v v−1 in SBR1 and SBR2). The results showed good chemical oxygen demand (COD) removal efficiency for both reactors, with average C…
Occurrence and removal of organic pollutants in sewages and landfill leachates
2002
Sewages of different composition and the effluents of four sewage treatment plants (STPs), plus sewage sludges were analysed for semivolatile organic priority pollutants. Furthermore, 11 landfill leachates were analysed to evaluate their contribution to sewage pollutants when co-treated. Bis(2-ethylhexyl) phthalate (DEHP) was the pollutant occurring at highest concentrations (up to 122 microg/l) and it was present in all sewages and leachates; concentrations of other phthalates were usually below 17 microg/l. Some polycyclic aromatic hydrocarbons (PAH) (<1 microg/l) and 2,6-dinitrotoluene (< or =5.9 microg/l) were also present in many of the sewages and leachates. Phthalates were present in…
La fidélité des consommateurs : une tentative de synthèse
2008
The aim of this article is to offer a synthesis of a very important concept in marketing. After having analysing the definitions of loyalty and their evolution, an overview of theoritical explanation is presented and four main processes based on different theories are identified. The aim is to understand how these theories can be integrated in a general model, in order to open up new avenues of thought.
