Measurements of Top Quark Properties at the Tevatron

The precise measurement of the top quark properties is a stringent test of the Standard Model of Particles and Fields. This reports presents the latest results from the CDF and D0 collaborations with an integrated data sample of up to 2.3/fb.Comment: 4 pages, 0 figures, proceedings for the 2008 QCD session of Morion

Deterministic Quantum Distribution of a d-ary key

We present an extension to a d-ary alphabet of a recently proposed deterministic quantum key distribution protocol. It relies on the use of mutually unbiased bases in prime power dimension d, for which we provide an explicit expression. Then, by considering a powerful individual attack, we show that the security of the protocol is maximal for d=3.Comment: 12 pages, 2 figure

Fundamental Rights of workers in the Digital Age: A methodological approach from a case study. WP C.S.D.L.E. "Massimo D'Antona" .INT - 89/2011

The relationship between employer and worker is not only obligatory but above all, as Sinzheimer said, a ‘relationship of power’. In the Digital Age this statement is confirmed by the massive introduction of ICT in most of the companies that increase, in practice, employer’s supervisory powers. This is a worrying issue for two reasons: on one hand, ICT emerge as a new way to weaken the effectiveness of fundamental rights and the right to dignity of workers; and, on the other hand, Spanish legal system does not offer appropriate solutions to ensure that efficacy. Moreover, in a scenario characterized by a hybridization of legal systems models –in which traditional hard law methods are combined with soft law and self regulation instruments–, the role of our case law has become very important in this issue. Nevertheless, despite the increase of judicialization undergone, solutions offered by Courts are so different that do not give enough legal certainty. Facing this situation, I suggest a methodological approach –using Alchourron and Bulygin’s normative systems theory and Alexy’s fundamental rights theory– which can open new spaces of decision to legal operators in order to solve properly these problems. This proposal can allow setting a policy that guarantees fundamental rights of workers, deepening their human freedom in companies from the Esping-Andersen’s de-commodification perspective. With this purpose, I examine electronic communications in the company as a case study
