Social anxiety and self-concept in adolescence

This study analyzes the relationships between social anxiety and dimensions of self-concept in a sample of 2022 (50.1% males) Spanish adolescents, ranging in age from 12 to 16 year-olds. The social anxiety was assessed by the Social Phobia and Anxiety Inventory (SPAI), and self-concept was measured with the Self-Description Questionnaire II (SDQ-II). Logistic regression analyses show that adolescents with social anxiety are more likely to negatively perceive their relationship with opposite sex peers and have lower scores in self-esteem than students without social anxiety. Furthermore, in most logistic models, students with social anxiety also show a higher probability of perceiving their relation with peers of the same sex in a negative way, considering worse student, less attractive and athletic, and more emotional instable than students without social anxiety. The relevance of sex and grade in the relationship between social anxiety and self-concept in adolescence is discussed.

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.

Vida Triste y Buen Vivir según personas adultas mayores en Otavalo, Ecuador

El presente trabajo se basa en el diagnóstico inicial previo de un proyecto de cooperación con una entidad social del Cantón de Otavalo (Ecuador), para incluir la actividad física y el juego en su programa de atención integral de Personas Adultas Mayores (PAM) en situación de indigencia. Para conocer el contexto de la población del servicio, sus experiencias previas y sus expectativas, se realizó una investigación basada en sus historias de vida. A su vez, se analizaron las políticas públicas del Buen Vivir y las políticas específicas para personas adultas mayores, analizando la legislación vigente y efectuando entrevistas en profundidad a informantes clave. Con enfoque interdisciplinar, se exponen reflexiones sobre elementos constitutivos de la Vida Triste y Buen Vivir, se destaca la importancia de la intervención integral en la promoción del Buen Vivir de PAM a partir de su pasado, sus puntos de vista y recursos de apoyo del territorio.
