Physical inactivity is a major contributor to morbidity and mortality worldwide. Many physical activity behavioral interventions at present have shown limited success addressing the problem from a long-term perspective that includes maintenance. This paper proposes the design of a decision algorithm for a mobile and wireless health (mHealth) adaptive intervention that is based on control engineering...
Mobile and wireless health (mHealth) interventions offer the opportunity for applying control engineering and system identification concepts in behavioral change settings. Social Cognitive Theory provides a recognized theoretical framework that can be applied to explain changes in behavior over time. Based on earlier work describing a dynamical model of this theory, a semi-physical system identification...
Social Cognitive Theory (SCT) is among the most influential theories of health behavior and has been used as the conceptual basis of interventions for smoking cessation, weight management, and other related health outcomes. SCT and other related theories were developed primarily to explain differences between individuals, but explanatory theories of within-person behavioral variability are increasingly...
The context of the European Space of Higher implies new Telecommunication Engineers trained in technical knowledge and professional skills. Problem-Based Learning and Project-Based Learning (PBL) are appropriate to achieve an effective learning of these skills. This paper presents a design of project-based learning course in Telecommunications Engineering degree from the University of Extremadura...
The development of skills through active learning methodologies has been demonstrated to be appropriate in environments where students must acquire particular professional capacities. Problem-Based Learning (PBL) embeds strudents' learning processes in real-life problems so, they can integrate different subjects in a common project that they need to solve in a self-directed way. In this context, we...
The emergence of the Internet has changed the nature of face-to-face towards online interactions. This leads to the concept of virtual interoperation such as Web Services, Grid, and Cloud Computing. Since existing security mechanisms are insufficient to cover the diversity of workflow application domains, trust is considered as an adaptive, high-level abstraction, and platform-independent solution...
This paper describes an approach to the formulation and classification of security requirements in eScience. It explains why it is untenable to suggest that `one size fits all', and that what is an appropriate security solution in one context may not be at all appropriate in another. It proposes a framework for the description of eScience security in a number of different dimensions, in terms of measures...
This paper presents a belief function approach for the location distribution of a search object in an optimal search planning context. We propose several ways to update the negative information obtained following an unsuccessful search mission using a belief functions framework. The discrete search space is defined by cells. We first represent the location information at the cell scale. We then generalize...
