The emigration literary culture which is formed in this exile is not very abundant, but with distinct trends between certificating and documenting the experiences of immigrants. Reportages play an important role, including A Sud di Lampedusa. Cinque anni di viaggi sulle rotte dei migranti by Stefano Liberti, A Lampedusa. Affari, malaffari, rivolta e sconfitta dell＇isola che voleva diventare la porta d＇Europa, a book written by Italian journalists Fabio Sanfilippo and Alice Scialoja, and a diary La scelta di Catia written by Catia Pellegrino. In addition, many materials （including journalistic materials） confirm the existence of a preliminary reconnaissance, however, requires further research. Italian documentaries, personal opinions and comments that go far beyond literature in the strict sense complement the panorama of contemporary emigration which comes from Africa and the Near East. However, they allow us to understand better the area of psychosocial determinants of individual migration decisions and specificity of the migrants＇ experience, including the experience of the community. How do human solidarity and effectiveness work in the process of the emigration on the European continent？ An analysis of the phenomenon of the emigration on the Apennine Peninsula is inextricably linked with the questions about the confrontation and integration, about the literature which is created in this community and the impact political correctness has on its shape, as well as about the new model of immigrant/the African/the European.展开更多

It was always one of the main objectives of any successful general theory of high energy particle physics and quantum cosmology to keep non-physical negative norms, the so called ghosts completely out of that theory. The present work takes the completely contrary view by admitting these supposedly spurious states as part of the physical Hilbert space. It is further shown that rethinking the ghost free condition with the two critical spacetime dimensions D<sub>1</sub> = 26 and D<sub>2</sub> = 25 together with the corresponding intercept a<sub>1</sub> = 1 and a<sub>2</sub> ≤ 1 respectively and in addition imposing, as in Gross et al. heterotic superstrings, an overall 496 dimensional exceptional Lie symmetry group, then one will discover that there are two distinct types of energy. The first is positive norm ordinary energy connected to the zero set quantum particles which is very close to the measured ordinary energy density of the cosmos, namely E(O) = mc<sup>2</sup>/22. The second is negative norm (i.e. ghost) energy connected to the empty set quantum wave and is equal to the conjectured dark energy density of the cosmos E(D) = mc<sup>2</sup> (21/22) presumed to be behind the observed accelerated cosmic expansion. That way we were able to not only explain the physics of dark energy without adding any new concepts or novel additional ingredients but also we were able to compute the dark energy density accurately and in full agreement with measurements and observations.展开更多
