First-order actions: A new view

We analyse systems described by first-order actions using the Hamilton-Jacobi (HJ) formalism for singular systems. In this study we verify that generalized brackets appear in a natural way in HJ approach, showing us the existence of a symplectic structure in the phase space of this formalism.

C-TPAT and AEO: new channels for world trade

This edition of the FAL Bulletin analyses the requirements of and the advantages offered by the Customs-Trade Partnership Against Terrorism (C-TPAT) of the United States and the Authorized Economic Operator (AEO) programme implemented by the European Union.Supply chain security, especially for foodstuffs, has grown considerably in importance in recent years, owing to a combination of different factors which are emerging or becoming more significant, making the requirement of ensuring that a cargo is harmless increasingly essential and valuable during trade negotiations.In the field of certifying the harmlessness of a cargo, a number of private-sector standards have arisen worldwide, but the benefits offered by the C-TPAT and AEO programmes are well above those of their private-sector counterparts.As a first step, a comparative analysis of the programmes implemented by the two largest markets in the northern hemisphere is needed in order to provide to Latin American and Caribbean exporters the information they need in order to modify or tailor their installations and production procedures, to achieve greater market entry.

Complex sochastic boolean systems : new properties of the intrinsic order graph

[EN]A complex stochastic Boolean system (CSBS) is a system depending on an arbitrary number n of stochastic Boolean variables. The analysis of CSBSs is mainly based on the intrinsic order: a partial order relation defined on the set f0; 1gn of binary n-tuples. The usual graphical representation for a CSBS is the intrinsic order graph: the Hasse diagram of the intrinsic order. In this paper, some new properties of the intrinsic order graph are studied. Particularly, the set and the number of its edges, the degree and neighbors of each vertex, as well as typical properties, such as the symmetry and fractal structure of this graph, are analyzed…

Report of the ESIL IEL IG Göttingen Conference on PTAs and World Economic Order

Presentation of the main findings of the first ESIL IEL IG Conference in Göttingen in March 2014. The conference provided a thorough overview over all of the current legal issues relating to preferentialism. Particularly the discussions on the role of academia in solving these new challenges in global trade regulation were perceived as fruitful and inspiring.
