't Hooft loop and the phases of SU(2) LGT

We analyze the vacuum structure of SU(2) lattice gauge theories in D=2,3,4, concentrating on the stability of 't Hooft loops. High precision calculations have been performed in D=3; similar results hold also for D=4 and D=2. We discuss the impact of our findings on the continuum limit of Yang-Mills theories.Comment: 7 pages, 3 figures.

Non perturbative study of QCD on a 2+2 anisotropic lattice

We present preliminary results for a non perturbative determination of the parameters in the action required to restore Lorentz invariance in long distance correlators, using the static interquark potential. Comparison with analytical results is made and further applications are discussed.Comment: 3 pages, Lattice2003 (improvement

Colti in trappola. L’università postfordista e la formazione del cognitariato

In post-Fordism has now emerged the figure of cognitive workers, who work through communication, symbols and the relationship. Among these should be placed also precarious intellectual workers, that the article fits into the theorist landscape of Italian post-operaism. The analysis deals with the plan of social building and education of precarious cognitive workers. In this perspec-tive, the precarious researchers of Italian universities (PhDs, PostDocs, tem-porary teachers etc.) appear to play a central role because they exploit themself and simultaneously educate cognitive workers of postfordism into submission and obedience. To this aim seems to tend the process of restructuring of the university system.
