Combining the rational and relational perspectives of electronic trading

Many organisations make extensive use of electronic linkages to facilitate their trading exchanges with partners such as suppliers, distributors and customers. This research explores how the use of inter-organisational systems (IOS) both affects, and is affected by, the relationships between trading partners. In doing this, it brings together two existing but distinct perspectives and literatures; the rational view informed by IOS research, and the behavioural or relationship perspective embodied in inter-organisational relationships (IOR) literature. The research was undertaken in the European paper industry by means of six dyadic case studies. The dyads studied covered both traditional electronic data interchange systems and newer e-marketplace environments. A framework was derived from existing literature that integrates the two perspectives of interest. The framework was used to analyse the case studies undertaken and enabled the inter-relationship between IOS use and IOR to be explained.

Augmented Reality for Games

In this text, we intend to explore augmented reality as a means to visualise interactive communication projects. With ARToolkit, Virtools and 3ds Max applications, we aim to show how to create a portable interactive platform that resorts to the environment and markers for constructing the game’s scenario. We plan to show that the realism of simulation, together with the merger of artificial objects with the real world, can generate interactive empathy between players and their avatars.

The uncanny valley, notes on the realism of “living” creatures in digital games and their relationships with the player

Neste artigo argumenta-se que as simulações numéricas fomentam e exploram relações complexas entre o jogador e o sistema cibernético da máquina que com este se relaciona através da jogabilidade, ou seja, da real aplicação às regras de jogo de tácticas e estratégias usadas pelo participante durante o seu trajecto na aplicação lúdica. Considera-se que o espaço mágico imposto pelo tabuleiro de jogo é mais do que um espaço de confusão entre real e artificial mas antes se apresenta como uma cortina ou interface entre o corpo próprio do participante e a simulação digital inerente ao sistema computacional.

Ball Recovery in the Handball Tournament of the 2008 Beijing Olympic Games: Sequential Analysis of Positional Play as Used by the Spanish Team’s Defence

In sport there is a great need to obtain as much information as possible about the factors which affect the dynamics of play. This study uses sequential analysis and temporal patterns (T-patterns)to examine the evolution of defence (against an equal number of attackers)as used by the Spanish handball team at the Beijing 2008 Olympic Games. The aim is to help handball coaches (during their training and gathering of professional experience)to understand the importance of the structure of defensive systems. This can be achieved through observational processes that reveal the evolution and adaptation of these defensive systems according to different variables: the match score, the response of the opposing team and progress through the tournament.
