'A Deep Trade Agenda': The convergence of trade and Fundamental Rights

A key feature of the latest EU trade negotiations was the pursuance of a “deep trade agenda” for “deep integration” with the trade partners. The concept of “deep” has yet remained unexplored from a fundamental rights perspective. The central question of this chapter asks how a methodological framework of “convergence” can help the exploration and understanding of “deepness of fundamental rights” in the new generation of EU trade agreements. Using the Civil Society Forum under CETA as a case-study, the chapter argues that while convergence can justify the targeting of certain analytical elements as opposed to others, its usefulness remains limited for more normative explorations

Different realizations of tomographic principle in quantum state measurement

We establish a general principle for the tomographic approach to quantum state reconstruction, till now based on a simple rotation transformation in the phase space, which allows us to consider other types of transformations. Then, we will present different realizations of the principle in specific examples.Comment: 17 pages, Latex file, no figures, accepted by J. of Mod. Op

A probabilistic approach to quantum mechanics based on tomograms

It is usually believed that a picture of Quantum Mechanics in terms of true probabilities cannot be given due to the uncertainty relations. Here we discuss a tomographic approach to quantum states that leads to a probability representation of quantum states. This can be regarded as a classical-like formulation of quantum mechanics which avoids the counterintuitive concepts of wave function and density operator. The relevant concepts of quantum mechanics are then reconsidered and the epistemological implications of such approach discussed

Fundamental rights in the institutional architecture of EU trade agreements: a tale of omissions

This paper explores the institutional dimension of the implementation of the new generation EU Free Trade Agreements (FTAs) from a fundamental rights perspective. The creation of an institutional architecture of EU FTAs is what makes them operational. It enables the other dimensions to become “alive” and not to remain words within a text. Given the plethora of entities created by the new generation of EU FTAs, this paper investigates the extent to which the institutional architecture of EU FTAs is adequate to protect and promote fundamental rights. This investigation shows that, despite significant novelties, several limitations remain. Gaps in the mandate and deficiencies in the decision-making processes lead to foresee little consideration of fundamental rights at the implementation stage

Collective spontaneous emission in a q-deformed Dicke model

The q-deformation of a single quantized radiation mode interacting with a collection of two level atoms is introduced, analysing its effects on the cooperative behavior of the system.Comment: 11 pages, RevTeX file, 2 figures available from authors, accepted for publication in Mod. Phys. Lett.

Beyond the Standard "Marginalizations" of Wigner Function

Was It Something I Ate? Implementation of the FDA Seafood HACCP Program

We use FDA’s seafood inspection records to examine: (i) how FDA has targeted its inspections under HACCP regulation; (ii) the effects of FDA inspections on compliance with both HACCP and plant sanitation standards; and (iii) the relationship between HACCP regulations and pre-existing sanitation standards. We use a theoretical model of enforcement to derive hypotheses about FDA’s targeting of inspections and firms’ patterns of compliance. We test those hypotheses using econometric models of inspection and compliance. Contrary to the predictions of the theoretical model and to FDA’s own stated policies, FDA does not seem to have targeted inspections based on product risk or past compliance performance. Firms’ compliance strategies seemed to be broadly in accord with the predictions of the theoretical model. The threat of inspection increased the likelihood of compliance, although the deterrent effect was statistically significant for sanitation standards but not for HACCP. Firms tend to persist in compliance status, especially with respect to sanitation standards. Contrary to FDA’s presupposition, however, HACCP compliance does not improve compliance with sanitation standards, suggesting that the two are not complementary.HACCP, Food safety, Seafood, Enforcement, Regulatory compliance, Regulation

A generating functional approach to the Hubbard model

The method of generating functional is generalized to the case of strongly correlated systems, and applied to the Hubbard model. For the electronic Green's function constructed for Hubbard operators, an equation using variational derivatives with respect to the fluctuating fields has been derived and its multiplicative form has been determined. Corrections for the electronic self-energy are calculated up to the second order with respect to the parameter W/U (W width of the band), and a mean field type approximation was formulated, including both charge and spin static fluctuations. The equations for the Bose-like Green's functions have been derived, describing the collective modes: the magnons and doublons. The properties of the poles of the doublon Green's functions depend on electronic filling. The investigation of the special case n=1 demonstrates that the doublon Green's function has a soft mode at the wave vector Q=(pi,pi,...), indicating possible instability of the uniform paramagnetic phase relatively to the two sublattices charge ordering. However this instability should compete with an instability to antiferromagnetic ordering.Comment: 31 pages, 7 figures, to be published in Eur. Phys. J.

Density Matrix From Photon Number Tomography

We provide a simple analytic relation which connects the density operator of the radiation field with the number probabilities. The problem of experimentally "sampling" a general matrix elements is studied, and the deleterious effects of nonunit quantum efficiency in the detection process are analyzed showing how they can be reduced by using the squeezing technique. The obtained result is particulary useful for intracavity field reconstruction states.Comment: LATEX,6 pages,accepted by Europhysics Letter
