Unpacking Knowing Integration: A Practice-based Study in Haute Cuisine

Nous proposons d'analyser l'intégration des connaissances à la source d'un avantage concurrentiel avec une approche pratique des organisations. Alors que la littérature s'est focalisée sur le transfert de connaissances et les relations entre communautés par le biais des objets frontière, nous considérons les relations intra-communauté et la façon dont les acteurs mobilisent, restructurent et créent des connaissances pour l'action. Dans une perspective pratique, la dynamique des connaissances est un phénomène situé dans un contexte social donné. Nous nous appuyons sur une phase empirique qualitative, par l'analyse de l'intégration des connaissances lors de la création de nouveaux plats au sein des équipes de cuisiniers de restaurants tri-étoilés.Apprentissage ; Avantage concurrentiel ; Connaissance ; Créativité ; Gastronomie ; Integration ; Transfert

The Social Dimensions of Idea Work in Haute Cuisine: A Bourdieusian Perspective

This paper analyzes idea work in haute cuisine through three case studies. Mobilizing Bourdieu’s praxeology, we consider idea work as a practice, an activity that takes sense and meaning in the social world. Thus, idea work reflects the position of the agent in the field and the struggles to maintain or improve this position. In grand restaurants, the chefs play a key role in idea work, even if they involve other people. Idea work is rooted in their personal experience, but is also shaped by the restaurant’ style and haute cuisine rules. Idea work relates to chefs’ reflection as well as emotions and feelings.Bourdieu; Creativity; Field; Habitus; Haute Cuisine; Gastronomy; Practice

The Social Dimensions of Idea Work in Haute Cuisine: A Bourdieusian Perspective

Nous proposons de définir la production d'idées comme une pratique, c'est-à-dire comme une activité qui prend son sens et sa valeur dans un contexte social, pour analyser le travail créatif dans les cuisines de trois grands restaurants.Créativité ; Gastronomie ; Idées ; Pratique

Unpacking Knowing Integration: A Practice-based Study in Haute Cuisine

Within a practice-based approach of organizations, we explore the knowing integration phenomena at the roots of competitive advantage. While former knowing integration studies have pointed to the importance of boundary objects across occupational communities, knowing integration inside a community to ground competitive advantage remains to be explored. How do individuals integrate their knowing in practice, in complex and important situations in order to contribute to competitive advantage for the firm? We ground our analysis on the ethnographic study of performed tasks in new dishes creation in two gourmet restaurants. We trace individual knowing in this creation to highlight how a new dish emerges from knowing integration, based on our understanding of knowing as processual, social, and situated. We propose a model of knowing integration as a combination of three phenomena: comprehending, interpreting and explicitating. We show that integration leads to the development of new dishes while knowing remains largely individual. We therefore suggest that there exists a clear distinction between knowing integration and knowledge sharing or transfer. We also contribute to a clearer delineation between integration and explicitation, the latter being only one and secondary means to achieve the former. Our study advances practice-based studies of organizations by highlighting the central role of integration in knowing dynamics and by bridging micro and macro perspectives on practice.Combination; Competitive Advantage; Integration; Knowledge; Learning; Restaurants; Transfer

Fractal dimension versus density of the built-up surfaces in the periphery of Brussels.

This paper aims at showing the usefulness of the fractal dimension for characterizing the spatial structure of the built-up surfaces within the periurban fringe. We first discuss our methodology and expectations in terms of operationality of the fractal dimension theoretically and geometrically. An empirical analysis is then performed on the southern periphery of Brussels (Brabant Wallon). The empirical analysis is divided into two parts: first, the effect of the size and shape of the windows on the fractal measures is empirically evaluated; this leads to a methodological discussion about the importance of the scale of analysis as well as the real sense of fractality. Second, we show empirically how far fractal dimension and density can look alike, but are also totally different. The relationship between density and fractality of built-up areas is discussed empirically and theoretically. Results are interpreted in an urban sprawl context as well as in a polycentric development of the peripheries. These analyses confirm the usefulness but also the limits of the fractal approach in order to describe the built-up morphology. Fractal analysis is a promising tool for describing the morphology of the city and for simulating its genesis and planning. Keywords: Fractals – dimension – periurbanisation – Brussels Note to the ERSA2004 referees: This is the state of our paper on April 30th 2004. It is not finished nor checked by an English native but results seem quite promising.

Characterisation of the immunological events induced by biodegradable polymer vaccines

This study was performed to unravel the adjuvant mechanisms of biodegradable microsphere vaccines based on poly (lactide-co-glycolide) (PLGA) polymer. Those microspheres have been extensively investigated as efficient vaccine adjuvant and delivery systems. However, their mode of action and their in vivo processing remain unclear. A better understanding of the adjuvant mechanisms would prove essential for the design of new generation vaccines required to be safer, given in less doses and stable at room temperature. This study focused on the sub-cutaneous administration of encapsulated protein models diphtheria and tetanus toxoids (DT and TT). The experimental work covered three aspects: (i) the uptake and transport of subcutaneously injected PLGA MS DT by macrophages and dendritic cells in vivoin mice; (ii) the influence of physico-chemical properties of the PLGA MS formulations on the toxoids immunogenicity in mice and guinea pigs; (iii) the immunogenicity of a multivalent encapsulated PLGS MS loaded with individual or multiple childhood vaccine antigens. This is probably the first study on the particle uptake and biodistribution of sub-cutaneously injected PLGA MS by antigen presenting cells in mice. Tracking of the fluorescent particles by microscopy confirmed previously postulated adjuvant mechanisms such as the depot effect at the injection site mimicking multiple injections; the efficient uptake of the particles by antigen presenting cells (APCs) and the active transport and relocalisation of the particles within lymphoid organs via APCs. These mechanisms were influenced mainly by the hydrophobic nature of the polymer and the size of the microspheres. When the formulation was optimized, a single dose of microencapsulated vaccine on its own (without addition of a potent adjuvant) protected better than two doses of the commercial alum-adsorbed vaccine. This study also demonstrates the feasibility of a multivalent paediatric encapsulated vaccine based on diphtheria, tetanus, pertussis and Hib antigens. The implementation of such a vaccine in the immunisation schedule would be a major achievement in the reduction of the number of injections given to the infants
