This paper examines the specific impacts of market-oriented coopetition on product commercial performance. Indeed, most contributions have focused on technology-driven coopetition with cooperation on activities that are far from the market (e.g., production, R&D), whereas most coopetitive agreements involve market-oriented coopetition in which the cooperation arises in activities that are close to the market (e.g., marketing, distribution). We first present the specificities of market-oriented coopetition and distinguish horizontal and vertical marketoriented coopetition. We then focus on the performance implications of market-oriented coopetition. Building on social network exchange theory, we elaborate a theoretical framework detailing the mechanisms through which market-oriented coopetition affects product commercial performance. Using a database from the real estate brokerage industry, we validate our hypotheses that horizontal market-oriented coopetition enhances product commercial performance compared to competition, whereas vertical market-oriented coopetition does not. Furthermore, we highlight the existence of a learning effect for horizontal market-oriented coopetition. This research contributes to coopetition theory by defining market-oriented coopetition and studying its performance implications.

Concurrent dewatering and slope depressurization operations have been underway at the Escondida open pit since 1996. A hydrogeological investigation has been undertaken as part of the depressurization operation on the north wall. It has shown that there are two distinct hydrogeological units in the slope, the altered and unaltered Escondida Porphyry. The hydrothermally altered Escondida Porphyry is clay rich and has relatively high matrix permeability. The underlying silicified, or unaltered porphyry, has very low matrix permeability and groundwater flow is in steeply dipping NW-trending fracture systems. Pore pressures in the silicified porphyry are higher than the altered material.A system of horizontal drains and vertical wells has been in operation to reduce pore pressures in the altered porphyry. To investigate effective drainage measures for the silicified porphyry, a groundwater model of the slope was constructed. This analysis showed that a drainage tunnel with horizontal drains was the most effective method of draining significant areas of the slope to the required pore pressure targets.

La coopétition est une stratégie porteuse de performances et de risques pour les entreprises. Ceci est également vrai pour les petites entreprises (PE). Les recherches antérieures montrent qu’elles peuvent bénéficier de la coopétition, mais qu’elle se traduit par des tensions et des conflits destructeurs de valeur. La coopétition doit donc être managée pour être performante. Les recherches antérieures ont mis en évidence le management interne de la coopétition en PE, mais pas les dispositifs interorganisationnels. Un cadre théorique fondé sur la loi proxémique a donc été développé, comportant quatre points fondamentaux : les PE en coopétition forment une communauté séparée des autres compétiteurs par un phénomène de paroi ; les PE en coopétition développent un fort sentiment d’appartenance à la communauté ; il y a une hiérarchie des membres à l’intérieur du réseau coopétitif ; la paroi de la communauté coopétitive n’est pas totalement hermétique, car il y a des portes d’entrée et de sortie. La pertinence du cadre théorique est évaluée en étudiant les PE de l’industrie des agences immobilières en France. Les résultats montrent tout l’intérêt de la coopétition pour les PE et que les quatre traits caractéristiques de la coopétition en PE sont bien présents.

Technique as the entanglement of composition and performance as an epistemic object (Knorr Cetina) emergent from contingent materiality. Two pieces by Scott McLaughlin—respectively for Zubin Kanga (piano) and Mira Benjamin (violin)—are discussed as case studies of strategies for entwining the specific embodied techniques of instrumental performance with the material agency (Pickering) of the instrument as a 'material indeterminacy' in which knowledge inheres through practice (Spatz). This exposition situates the artistic research as a novel conceptualisation of 'technique' that treats composition and performance not as separate domains but as an Ingoldian 'meshwork' where virtual structures in the performance technique are amplified through processes of listening and through compositional structures into open-ended local feedback loops.
