Lorentz invariance for mixed neutrinos
We show that a proper field theoretical treatment of mixed (Dirac) neutrinos
leads to non-trivial dispersion relations for the flavor states. We analyze
such a situation in the framework of the non-linear relativity schemes recently
proposed by Magueijo and Smolin. We finally examine the experimental
implications of our theoretical proposals by considering the spectrum and the
end-point of beta decay in tritium.Comment: 8 pages, 4 figures. Presented at 2nd International Workshop DICE2004:

Between “ghettos”, “safe spaces” and “gaytrification”: exploring the specificities of LGBT neighbourhoods in southern Europe
In recent decades, “LGBT neighbourhoods” or “gay Villages” have been
gaining some prominence and particular characteristics within cities,
representing safe spaces for the expression and negotiation of individual and
collective identities as well as for the political affirmation of LGBT
communities and queer identities. As other areas that have been the main
drivers of urban revitalization of inner-cities, such as cultural and creative
quarters or multicultural spaces, these territories distinguish for the social
practices of their users and inhabitants, the specificities of their economic
activity, or their contribute to creativity or social integration. More than
community ghettos, these areas have been characterized by their openness and
vibrancy, enhancing the coexistence of diverse lifestyles, trajectories and
identities, but also by the contribution of LGBT people to the gentrification of
these districts through their strong commercial, residential and symbolic
presence.
Drawing upon an empirical work developed in Lisbon (PrĂncipe Real district)
and Madrid (Chueca district), based on in-depth interviews to LGBT residents
and participant observation in the two neighbourhoods, this paper characterizes
the main evolutionary trajectories and specificities of these two districts. An
analysis is made confronting the characteristics and contingencies of these
areas with other cases previously studied in literature, identifying the existence
of notable differences and suggesting evidence of significant specificities,
which can represent a “South European” approach to the reality of “Gay
Villages”. Some generic principles for urban planning are drawn out from the

La réforme pénale et la réciprocité des droits
This letter deals with two major questions. The first shows how the “program” of criminology which emerged in the 19th century contributes to a neutralisation of the impact of discussions concerning human rights in the case of punishment. To do this, the author compares two paradigms of penal reform. The second question tries to clarify the relations established in Quebec between the rights of prisoners and abolitionist alternatives from 1975 on
La réforme pénale au Canada : l’apport de la Commission canadienne sur la détermination de la peine
This study is a critical analysis of the penal reform project put forward by the Canadian Commission on Sentencing from the point of view of moderation. The author first considers the Commission's position in the penological debate between the Medical Model and the Justice Model. He then analyses the “new theory on sanctions” proposed by the Commission, as well as its position on “community measures” and on the ideal of rehabilitation. Finally, his analysis focuses on a number of the Commission's major recommendations for reform, its policy in terms of maximum and minimum sentences, the new “exceptional sentence” (intended to replace the present measures regarding “dangerous criminals”), its position on imprisonment of “twenty-five years' minimum” and its general guidelines for Canada. In conclusion, the author make an evaluation of the orientation of the Commission's reform with respect to the principle of moderation
