Glial cell line-derived neurotrophic factor (GDNF) is absolutely required for survival of dopaminergic (DA) nigrostriatal neurons and protect them from toxic insults. Hence, it is a promising, albeit experimental, therapy for Parkinson's disease (PD). However, the source of striatal GDNF is not well known. GDNF seems to be normally synthesized in neurons,(More)
We report research investigating the role of mental models in deduction. The first study deals with conjunctive inferences (from one conjunction and two conditional premises) and disjunctive inferences (from one disjunction and the same two conditionals). The second study examines reasoning from multiple conditionals such as: If e then b; If a then b; If b(More)
This work proposes a framework for the design and development of Ontology Agents oriented to manage Rule Base Fuzzy Cognitive Maps (RBFCM). The approach takes into account the foundations of the Ontology Agents and the baseline of the Fuzzy Cognitive Maps depicted by Rule Bases. With these underlying elements, a specification of a conceptualization about(More)
The aim of this study was to investigate the effects of an intervention program to promote active text-processing strategies (main-idea identification and summarization) at two developmental levels (12- and 16-year-olds). The independent variables were training condition (experimental and control) and school level (7th and 10th grades). Several measures(More)
This paper introduces a service-oriented model for the development of Peer-to-Peer (P2P) systems. We first describe the set of abstract primitives supported by the model, and then the semantics for a simple calculus over these primitives that provides a solid ground to develop tools for the analysis and verification of P2P specifications.
Augmented reality is a technology that involves digital content deployed in the physical world in real time through the use of devices and sensors that allow users to interact with the resulting hybrid environment. Likewise, QR codes have become popular and accepted by the general public. They are useful for conveying information in the physical world and(More)
