Amygdala activation in response to 2D and 3D emotion-inducing stimuli

Studying changes in brain activation according to the valence of emotion-inducing stimuli is essential in the research on emotions. Due to the ecological potential of virtual reality, it is also important to examine whether brain activation in response to emotional stimuli can be modulated by the three-dimensional (3D) properties of the images. This study uses functional Magnetic Resonance Imaging to compare di...

Proteção auditiva : fatores de seleção e riscos da atenuação excessiva

Hearing protection : selection factors and risks of excessive attenuation

Currently, noise exposure in the occupational setting continues to be a problem in industrialized countries, not only because this is the most common occupational disease in these countries, but also because it is transversal to all activity sectors, including leisure activities. Exposure to high noise levels can affect the hearing system. For this reason, the legislation requires that the employer implement...

Mismatch negativity in childhood temporal lobe epilepsy: a proposed paradigm fo...

Background: Temporal lobe epilepsy (TLE) is a neurological disorder that directly affects cortical areas responsible for auditory processing. The resulting abnormalities can be assessed using event-related potentials (ERP), which have high temporal resolution. However, little is known about TLE in terms of dysfunction of early sensory memory encoding or possible correlations between EEGs, linguistic deficits, a...

Differences in Mismatch Negativity (MMN) response to Pure-tone and Speech sound...

The relation of automatic auditory discrimination, measured with MMN, with the type of stimuli has not been well established in the literature, despite its importance as an electrophysiological measure of central sound representation. In this study, MMN response was elicited by pure-tone and speech binaurally passive auditory oddball paradigm in a group of 8 normal young adult subjects at the same intensity lev...

Key factors affecting strategy-minded decision makers in their innovations choices

The rapid and continuous pace of technological change is a major challenge for all managers, who are often faced with innovations’ adoption decisions affecting the future of their companies. This is a fundamental issue on strategy, if we see strategy as a set of actions to make critical choices between two or more alternatives, in order to achieve competitive advantages or to respond to competitors. Strategy‐mi...

Business strategies in contexts of high uncertainty : a case study on the innov...

Innovation and internationalization of small and medium enterprises are widely cited as decisive factors, for the sustainable growth of European economies, which are facing a deep crisis. The European Union launched in March 2010 a European strategy, called Europe 2020, to prepare the EU economy for the future, where growth is based in three dimensions: smart, sustainable and inclusive. In the Portuguese case, ...

Generic roles: reducing code replication

In partial fulfillment of requirements for the degree of Doctor of Philosophy in Informatics Enginnering by the Doctoral Program in Informatics Engineering ; For many years the concept of modularity has been considered a very important part in the development of large software systems. Modules help to manage the system’s complexity by decomposing it in smaller parts. These parts can be assigned to individuals ...
