Rentabilidad de las empresas vinculadas a las marcas colectivas en el sector vinícola

El objetivo del trabajo consiste en analizar la rentabilidad de las empresas que integran una marca colectiva en el sector vinícola español. El supuesto básico es que la marca colectiva puede explicar la rentabilidad de las bodegas, porque la reputación colectiva es una señal de calidad que reduce las percepciones de riesgo del consumidor. Los resultados obtenidos evidencian que sólo algunas marcas colectivas tienen un efecto positivo en la rentabilidad de las bodegas en relación con las no acogidas a dichas marcas colectivas. Asimismo, la rentabilidad viene asociada positivamente a la diversificación de la bodega en dos o más marcas colectivas.

Augmented and Virtual Reality techniques for footwear

The use of 3D imaging techniques has been early adopted in the footwear industry. In particular, 3D imaging could be used to aid commerce and improve the quality and sales of shoes. Footwear customization is an added value aimed not only to improve product quality, but also consumer comfort. Moreover, customisation implies a new business model that avoids the competition of mass production coming from new manufacturers settled mainly in Asian countries. However, footwear customisation implies a significant effort at different levels. In manufacturing, rapid and virtual prototyping is required; indeed the prototype is intended to become the final product. The whole design procedure must be validated using exclusively virtual techniques to ensure the feasibility of this process, since physical prototypes should be avoided. With regard to commerce, it would be desirable for the consumer to choose any model of shoes from a large 3D database and be able to try them on looking at a magic mirror. This would probably reduce costs and increase sales, since shops would not require storing every shoe model and the process of trying several models on would be easier and faster for the consumer. In this paper, new advances in 3D techniques coming from experience in cinema, TV and games are successfully applied to footwear. Firstly, the characteristics of a high-quality stereoscopic vision system for footwear are presented. Secondly, a system for the interaction with virtual footwear models based on 3D gloves is detailed. Finally, an augmented reality system (magic mirror) is presented, which is implemented with low-cost computational elements that allow a hypothetical customer to check in real time the goodness of a given virtual footwear model from an aesthetical point of view.
