Torsion-Gravity and Spinors in Fundamental Theoretical Physics
No full textEinstein’s theory of gravitation is perhaps one of the best-established theories ever conceived. However, it is based on the hypothesis that space-time carries curvature alone, leaving torsion out. Because torsion is a natural part of the most general geometric background in which Einstein gravity is built, it is all too natural that the torsional completion of gravity should be considered. Constructing an underlying stage in which both curvature and torsion are present, the fact that curvature couples with energy suggests that torsion may couple with spin, which is the other conserved quantity in quantum field theory. Torsion-gravity with spinning matter is, therefore, a complete and self-consistent setting for modern physics, with potential applications wherever spin effects may be important, stretching from quantum mechanics to the standard models of particle physics and early cosmology. However, this fact is not as present in today’s literature as it might be. The scope of the present collection of papers is to bring together the wisdom of various experts in the field, so to make the present status of torsion in gravity and spin in quantum field theory clearer
RAPOPORT H. F., FABBRI A., SEBASTIANI L., 2016. Olive Biology. In Rugini, E., Baldoni, L., Muleo, R., Sebastiani, L. (Eds.), “The Olive Genome”, pp. 13-26. Springer, Heidelberg.
No full textThe olive is a medium-sized evergreen tree, which integrates a unique set
of morphological and developmental characteristics suited to the relatively
dry, rustic conditions of its Mediterranean origin. Also particular to the
olive tree are its numerous small fruits, which are rich in oil that is highly
appreciated for both flavor and health benefits. The Olea europaea species
includes both wild and cultivated forms, and both a long period of
domestication and the perseverance of wild varieties provide a range of
morphological variation, as does the developmental plasticity of this
species. This chapter reviews the general growth and taxonomy of the
olive tree and describes its vegetative and reproductive morphology and
anatomy. Basic structural features of the trunk and branches, leaves, roots,
flowers, fruits, and seeds are described. Current research is indicated for
the structures discussed, and information provided regarding adaptive
significance, environmental influences, and genetically based variability
among cultivars or between wild and cultivated genotypes

Learning to live in multicultural contexts: transformative theory contribution
No full textUsing the theory of transformative learning as a perspective that helps people to question and transform the codes of understanding and interpretation that they have acquired throughout their lives in different social contexts and through which their own experiences and actions are given meaning, the contribution presents and justifies the scientific and methodological background that made the F.O.R.W.A.R.D. project possible.
Following this theoretical framework, the approach to the topic of radicalization is "rethought" as a construct related to ordinary contexts, a micro-phenomenon resulting from ordinary rather than extraordinary interactions. This hypothesis allows to shift the focus from extremism, such as violence and terrorism, to a broader field, referring to the set of processes that are shaped in daily interactions between individuals in specific public arenas and geographical locations on which the project has focused. This allows the different communities involved to develop inclusive interpretive models of diversity management
Introduction [a Understanding radicalization in everyday life]
No full textThe term radicalization has been used over the past decades with different
interpretations. Coolsaet used the “catch-all concept” (2011, p. 261) to
define the trend that many constructs use one idea in reference to different
phenomena. Radicalization has, for many years, been synonymous with
terrorism, with a particular focus on violent radicalization rather than
radical meaning/thinking. Many other meanings in this sphere have been
developed and used. For example, Schmid notes that even within scholarly
and public debates not all forms of political violence are all-terrorist or allextremist
(Schmid, 2011).
Widespread uses and abuses of the term radicalization have appeared in
the media and more broadly in the public sphere. This has created
confusion regarding the various meanings of the term, and ultimately
delegitimizing the role that some forms of radicalism have had, throughout
history, in promoting democracy and social justice. It is therefore important
to reaffirm the distinction between violent radicalization and nonviolent
radicalization (Schmid, 2011).
We know that radicalization should not necessarily incorporate the idea
that a subject performs a violent act, or that the radical position assumed
may be connoted a priori as negative or dangerous
