The WTO from the Perspective of a Developing Country

This Essay starts by laying out the shortcomings of the WTO. In Part II it lays out the issues at stake in the Seattle Conference. Part III is about the effects of the Seattle fiasco. Part IV gives the author\u27s views on what a development round should be. Part V asserts that the WTO should promote fair labor standards. Finally, Part VI discusses the prospects for the WTO to address concerns of developing nations

Reggeon Interactions in Perturbative QCD

We study the pairwise interaction of reggeized gluons and quarks in the Regge limit of perturbative QCD. The interactions are represented as integral kernels in the transverse momentum space and as operators in the impact parameter space. We observe conformal symmetry and holomorphic factorization in all cases.Comment: 13 pages LATEX, 2 figures using package FEYNMAN, N4-9

Co-managing shared waters: a coastal governance experience of Western Visayas Region, Philippines

Coastal ecosystems in the Philippines are under stress from the combined effects of human overexploitation and habitat destruction. In recent years, the concept of an integrated approach to coastal resource management has been adopted to address this. This new paradigm, generally described as co-management, makes use of the participation of the different sectors (e.g. government, community) in the management process. CRMCs are multi-sectoral in nature with inter-LGU partnerships and different resource-sharing schemes. This is based on the premise that complex problems in coastal areas do not respect jurisdictional boundaries and can only be addressed in a meaningful way through collaboration with the different sectors involved and empowerment of the community. This paper will present the experiences of the different CRMCs in Western Visayas Region, Philippines and how the different LGUs surrounding a bay area have joined together to responsibly manage their common resource. Success stories or ôbest practiceö strategy of the CRMCs will also be highlighted for possible replication in other coastal communities.Fishery management, Coastal zone management, Resource management

Exact resolution of the Baxter equation for reggeized gluon interactions

The interaction of reggeized gluons in multi-colour QCD is considered in the Baxter-Sklyanin representation, where the wave function is expressed as a product of Baxter functions Q(lambda) and a pseudo-vacuum state. We find n solutions of the Baxter equation for a composite state of n gluons with poles of rank r in the upper lambda semi-plane and of rank n-1-r in the lower lambda semi-plane (0 leq r leq n-1). These solutions are related by n-2 linear equations with coefficients depending on coth (pi lambda). The poles cancel in the wave function, bilinear combination of holomorphic and anti-holomorphic Baxter functions, guaranteeing its normalizability. The quantization of the intercepts of the corresponding Regge singularities appears as a result of the physical requirements that the holomorphic energies for all solutions of the Baxter equation are the same and the total energies, calculated around two singularities lambda, lambda^* --> + i or -i, coincide. It results in simple properties of the zeroes of the Baxter functions. For illustration we calculate the parameters of the reggeon states constructed from three and four gluons. For the Odderon the ground state has conformal spin |m -m | = 1 and its intercept equals unity. The ground state of four reggeized gluons possesses conformal spin 2 and its intercept turns out to be higher than that for the BFKL Pomeron. We calculate the anomalous dimensions of the corresponding operators for arbitrary alpha_s/omega.Comment: LaTex, 42 pages, 8 .ps figures. Expanded and improved versio

Lattice isomorphisms of bisimple monogenic orthodox semigroups

Using the classification and description of the structure of bisimple monogenic orthodox semigroups obtained in \cite{key10}, we prove that every bisimple orthodox semigroup generated by a pair of mutually inverse elements of infinite order is strongly determined by the lattice of its subsemigroups in the class of all semigroups. This theorem substantially extends an earlier result of \cite{key25} stating that the bicyclic semigroup is strongly lattice determined.Comment: Semigroup Forum (published online: 15 April 2011

N=4 supersymmetric Yang Mills scattering amplitudes at high energies: the Regge cut contribution

We further investigate, in the planar limit of N=4 supersymmetric Yang Mills theories,the high energy Regge behavior of six-point MHV scattering amplitudes. In particular, for the new Regge cut contribution found in our previous paper, we compute in the leading logarithmic approximation (LLA) the energy spectrum of the BFKL equation in the color octet channel, and we calculate explicitly the two loop corrections to the discontinuities of the amplitudes for the transitions 2 to 4 and 3 to 3. We find an explicit solution of the BFKL equation for the octet channel for arbitrary momentum transfers and investigate the intercepts of the Regge singularities in this channel. As an important result we find that the universal collinear and infrared singularities of the BDS formula are not affected by this Regge-cut contribution. Any improvement of the BDS formula should reproduce this cut to all orders in the coupling

Regge Asymptotics of Scattering with Flavour Exchange in QCD

The contribution to the perturbative Regge asymptotics of the exchange of two reggeized fermions with opposite helicity is investigated. The methods of conformal symmetry known for the case of gluon exchange are extended to this case where double-logarithmic contributions dominate the asymptotics. The Regge trajectories at large momentum transfer are calculated.Comment: 18 pages LATEX, 3 figures using package FEYNMAN, N3-9
