As stated at the start of this article, psychological and physical demand states can be understood as the effects and consequences caused by loads. To deduce the physiological characteristics of psychophysical demand, theoretical concepts like the load/demand concept are commonly…

OBJETIVOS: Los objetivos se centraron en comprender y explicar cuál es significado que de los recursos naturales para las personas que viven con el VIH/SIDA (PVVS o PVV), desde la perspectiva de la antropología de los cuidados, de la misma…

El carácter transicional de la Ría de Aveiro le confiere una riqueza florística singular, integrando comunidades vegetales típicas de las
regiones Eurosiberiana y Mediterránea. La implantación del Proyecto Desenvolvimento Agrícola do Vouga (PDAV) va a provocar una
modificación de las…

Previous work on an interactive system aimed at helping non-expert users to enlarge the monolingual dictionaries of rule-based machine translation (MT) systems worked by discarding those inflection paradigms that cannot generate a set of inflected word forms validated by the…

In this paper a new conception of science is defined, which opposes apocalyptic points of view —science is a perverse knowledge leading to world destruction—, to irenist points of view —science is an armonic knowledge, as a puzzle where we…

This work presents the main theories and models formulated with the purpose of offering a global overview on the acquisition of knowledge and skills involved in the initial development of expert competence. Setting from this background, we developed an empirical…

We develop a theory to explain the transition from stagnation to modern growth. We focus on the forces that shaped the evolution of total factor productivity in agriculture and manufacturing across history. More specifically, we build a multisector model of…

Photopolymers are studied as holographic recording materials for recording computer-generated phase holograms. The recording was performed using a holographic copying process, in which the master is produced by means of a high resolution graphic device. To our knowledge it is…

The extension to new languages is a well known bottleneck for rule-based systems. Considerable human effort, which typically consists in re-writing from scratch huge amounts of rules, is in fact required to transfer the knowledge available to the system from…

Geographic knowledge discovery (GKD) is the process of extracting information and knowledge from massive georeferenced databases. Usually the process is accomplished by two different systems, the Geographic Information Systems (GIS) and the data mining engines. However, the development of those…
