It is known the protective role of personal resources in stress situations and changes (e.g. Van Den
Heuvel, 2010). Personal resources may help the individual to maximize from environmental
opportunities, to cope with difficulties, to persist when encountering difficulties and capitalize even
from failures. One of the most difficult and challenging work situation is certainly job loss.
The present study aims to emphasize the role of personal resources in a group of 874 call center

In the last decades, lighting has evolved from a branch of engineering ensuring safety and performance in indoor and outdoor installations, to a key discipline interacting with a wide spectrum of fields and having a deep impact on our daily lives. Although this evolution also applies to other areas of knowledge, the special features of lighting make its potential and also its limitations different. It is not the typical field where a well-established mathematical framework allows a departure from well-defined input and identifying clear effects and conclusions.

In previous papers, we proposed an extension of Spider Diagrams to object-oriented modelling, called Modelling Spider Diagrams (MSDs), as a visual notation for specifying admissible states of instances of types, and for verifying the conformance of configurations of instances with such specifications. Based on this formalisation, we developed a notion of transformation of MSDs, modelling admissible evolutions of configurations.
