Confirmatory Factor Analysis of the Behavioural Regulation in Exercise Questionnaire – Portuguese Version

Exercise constitutes one of the pillars of a healthy lifestyle (USDHHS, 1996). Paradoxically, more than 40% of Europeans are sedentary (Eurobarometer 213, 2004), although some interventions, at both community and individual levels, have been established to improve this situation. Some of these interventions are based on Self-Determination Theory (SDT: Deci & Ryan, 1985), which state that more internalized types of behaviour regulation lead to feelings of selfdetermination in one’s chosen activities and, consequently, to greater likelihood of behavioural adherence. Today, SDT is one of the most popular approaches to the study of exercise, thus the cross-cultural validation of instruments that can measure its constructs is a necessary step to further advance in the study of exercise motivation.

Robosonic: Randomness-Based Manipulation of Sounds Assisted by Robots

In this text, we intend to explore the possibilities of sound manipulation in a context of augmented reality (AR) through the use of robots. We use the random behaviour of robots in a limited space for the real-time modulation of two sound characteristics: amplitude and frequency. We add the possibility of interaction with these robots, providing the user the opportunity to manipulate the physical interface by placing markers in the action space, which alter the behaviour of the robots and, consequently, the audible result produced. We intend to demonstrate through the agents, programming of random processes and direct manipulation of this application, that it is possible to generate empathy in interaction and obtain specific audible results, which would be difficult to otherwise reproduce due to the infinite loops that the interaction promotes.

Determinants of portuguese wine & enotourism consumer behaviour

This study tries to understand what needs to be done to improve value perceptions and wine usage (1) Change the Portuguese wine and enotourism industry profile to adjust to huge competitive marketplace because it is still production-based; more sales than marketing oriented and the market data are less important then production and sales ones; (2) Enhance strongly the relationship between the wine and enotourism company and final consumers by “management synergies”; high “innovativeness to market”;“marketing research” and by an effective brand strategy. In this line, this paper provides an overview about strategic factors that determine the Portuguese wine and enotourism decision making process. The results of this research enable the essential features of a consumer profile of purchase and consumption to be obtained with respect to: (1) the structure of attributes - intrinsic and extrinsic - that Portuguese still wine consumers best recognise and value in determining its quality, (2) the motivational structures that encourage and guide them in their decision making process when purchasing and consuming wine and enotourism services, (3) the anticipated effect of interaction between different situations of consumption with different price bands.
