Masahiro Yoshida of the University of Tokushima described (Tetrahedron Lett. 2008, 49, 5021) the Pt-mediated rearrangement of alkynyl oxiranes such as 1 to the furan 2. Roman Dembinski of Oakland University reported (J. Org. Chem. 2008, 73, 5881) a related zinc-mediated rearrangement of propargyl ketones to furans. The cyclization of aryloxy ketones such as 3 to the benzofuran 4 developed (Tetrahedron Lett. 2008, 49, 6579) by Ikyon Kim of the Korea Research Institute of Chemical Technology is likely proceeding by a Friedel-Crafts mechanism. Sandro Cacchi and Giancarlo Fabrizi of Università degli Studi “La Sapienza”, Roma, observed (Organic Lett. 2008, 10, 2629) that base converted the enamine 5 to the pyrrole 6. Alternatively, oxidation of 5 with CuBr led to a pyridine. Zhuang-ping Zhuan of Xiamen University prepared (Adv. Synth. Cat. 2008, 350, 2778) pyrroles such as 9 by condensing an alkynyl carbinol 7 with a 1,3-dicarbonyl compound. Richard C. Larock of Iowa State University found (J. Org. Chem. 2008, 73, 6666) that combination of an alkynyl ketone 10 with 11 followed by oxidation with I-Cl led to the pyrazole 12. The “click” condensation of azides with alkynes, leading to the 1,4-disubstituted 1,2,3- triazole, has proven to be a powerful tool for combinatorial synthesis. Valery V. Fokin of Scripps/La Jolla and Zhenyang Lin and Guochen Jia of the Hong Kong University of Science and Technology have developed (J. Am. Chem. Soc. 2008, 130, 8923) a complementary approach, using Ru catalysts to prepare 1,5-disubstituted 1,2,3- triazoles. Remarkably, internal alkynes participate, and, as in the conversion of 13 to 15, propargylic alcohols direct the regioselectivity of the cycloaddition. A variety of methods have been put forward for functionalizing pyridines. Sukbok Chang of KAIST described (J. Am. Chem. Soc. 2008, 130, 9254) the direct oxidative homologation of a pyridine N -oxide 16 to give the unsaturated ester 18. Jonathan Clayden of the University of Manchester observed (Organic Lett. 2008, 10, 3567) that metalation of 19 gave an anion that rearranged to 20 with complete retention of enantiomeric excess. Shigeo Katsumura of Kwansei Gakuin University developed (Tetrahedron Lett. 2008, 49, 4349) an intriguing three-component coupling, combining 21, 22, and methanesulonamide 23 to give the pyridine 24.

Electronic commerce requires the redefinition of the firm’s relationships with partners, suppliers, and customers. The goal of effective customer relationship management (CRM) practice is to increase the firm’s customer equity, which is defined by the quality, quantity, and duration of customer relationships (Fjermestad & Romano, 2003). The explosive development of the online market and the rapid evolution of customer management applications have determined the companies to implement electronic customer relationship management (eCRM) systems, which are using advanced technology to enhance customer relationship management practices. The successful implementation of an eCRM system requires a specific combination of IT applications that support the classic domains of the CRM concept: marketing, sales, and service (Kennedy, 2006). Electronic marketing aims for acquiring new customers and moving existing customers to further purchases. Electronic sales try to simplify the buying process and to provide superior customer support. Electronic service has the task to provide electronic information and services for arising questions and problems or to convey customers to the right contact person in the organization. The eCRM system comprises a number of business processes, interlinked in a logical succession: • Market segmentation: The collection of historical data, complemented with information provided by third parties (such as marketing research agencies), is segmented on the basis of customer life-time value (CLV) criteria, using data mining applications. • Capturing the customer: The potential customer is attracted to the Web site of the firm through targeted promotional messages, diffused through various communication channels. • Customer information retrieval: The information retrieval process can be either implicit or explicit. When implicit, the information retrieval process registers the Web behaviour of customers, using specialized software applications, such as “cookies.” On the other hand, explicit information can be gathered through direct input of demographic data by the customer (using online registration forms or questionnaires). Often, these two categories of information are connected at database level. • Customer profile definition: The customer information collected is analyzed in relation with the target market segments identified through data mining, and a particular customer profile is defined. The profile can be enriched with additional data (e.g., external information from marketing information providers). This combination creates a holistic view of the customer, his needs, wants, interests and behaviour (Pan & Lee, 2003). • Personalization of firm-customer interaction: the customer profile is used to identify the best customer management campaign (CMC), which is applied to personalize the company-customer online interaction. • Resource management: The company-customer transaction require complex resource management operations, which are partially managed automatically, through specialized IT-applications, such as Enterprise Resource Planning (ERP) or Supply Chain Management (SCM), and partly through the direct involvement and coordination of operational managers.

Sous l’apparence d’une écriture dépouillée et d’une narration dénudée, Marie Redonnet, écrivaine contemporaine, nous présente un univers fictionnel peuplé de personnages –féminins pour la plupart- démunis et solitaires, soumis aux grandes tensions sociales, ancrés dans un cadre spatio-temporel flou, et fréquemment plongés dans un état d’abandon existentiel, de stagnation, auquel vient contribuer la présence d’une composante clé de l’imaginaire redonnetien: l’élément aquatique. Chez Redonnet, les différentes variantes de l’eau: océans, mers, fleuves, lacs, cascades, marécages, etc, deviennent d

Résumé: La recherche s'intéresse à la formation de Le Corbusier et à sa capacité d'abstraction au travers des mémoires, images liées à la connaissance du monde antique; un approfondissement qui traite le lien entre les œuvres du Maître et l'étude de l'architecture romaine, soulignant ainsi deux clés de lecture: une liée à l'archétype des modèles classiques, et une seconde liée aux ruines et à son paysage archéologique. Si la première laisse apparaitre clairement la composante rationnelle, volonté de poursuivre une architecture universelle, dans laquelle s'affirme l'utilisation de la raison que
