Title: Investor behavior in extreme situations of speculation and crash : an approach based on iterated prisoner’s dilemma Authors: Silva, Rui Miguel; Filipe, José António; Costa, Ana Abstract: This paper analyzes the investor behavior in situations of speculation and crash on stock markets. The investors’ main behavioral features are addressed, notably those related to cognitive and decision-making matters, in order to obtain an individual and an aggregated behavioral profile of the investor in situations of extreme events.

Title: Conceptualizing and measuring the economic issues in the evaluation of socio-ecological resilience : a commentary Authors: Mancini, Alberto; Salvati, Luca; Sateriano, Adele; Mancino, Giuseppe; Ferrara, Agostino Abstract: Resilience is the capacity of an ecosystem to tolerate disturbance without collapsing into a state controlled by a different set of environmental conditions and processes. Despite the growing importance of socioeconomic resilience, this concept has not been yet carefully defined or satisfactory measured within the more general issue of socio-ecological resilience of both natural (forest) and anthropogenic (agricultural) systems. Investigating socioeconomic resilience in a rapidly changing landscape is important for sustainable land management under intense and increasing human pressure, like observed in the Mediterranean region. This paper presents an overview of definitions and indicators of the socioeconomic resilience and comments on some possible measurements of the concept taken from the parallel ecological literature. The study is intended to contribute to this deserving issue in the light of the (increasingly complex) relationships between the environment, the economic systems, and the social sphere.

Title: Nanotechnology and processes : nano-photovoltaic panels as an innovation in energy market Authors: Chavagli, Jose; Filipe, Jose António; Ferreira, Manuel Alberto M.; Pacheco Coelho, Manuel Abstract: Nanotechnology can be a powerful weapon in creating competitive advantages in the energy market, through the use of the photovoltaic nanopanels, which may reduce production costs and simultaneously meet the socio-environmental requirements. It is a way to produce clean energy. Moreover, today the adoption of nanotechnology in energy production can make this kind of energy very interesting along the years, and fractal theory may help to show the effects. Nanotechnology may, in fact, be responsible for unimaginable gains, both economically and to preserve the planet.

Title: Output persistence in Portugal Authors: Caleiro, Antonio Abstract: The measurement of output persistence in Portugal is the main goal of this paper. By the use of a non-parametric methodology, it is shown that the level of output in Portugal exhibits a relatively high degree of persistence. This result is essential from a (contractionary/expansionary) policy point of view as the magnitude and duration of policy effects depend upon the level of persistence in output.
