Sport betting is a lucrative business for bookmakers, for the lucky (or wise) punters, but also for governments and for sport. While not new or even recent, the deviances linked to sport betting, primarily match-fixing, have gained increased media exposure in the past decade. This exploratory study is a qualitative content analysis of the press coverage of sport betting-related deviances in football in two countries (UK and France), using in each case two leading national publications over a period of five years. Data analysis indicates a mounting coverage of sport betting scandals, with teams, players and criminals increasingly framed as culprits, while authorities and federations primarily assume a positive role. As for the origin of sport betting deviances, French newspapers tend to blame the system (in an abstract way); British newspapers, in contrast, focus more on individual weaknesses, notably greed. This article contributed to the growing body of literature on the importance of these deviances and on the way they are perceived by sport organizations, legislators and the public at large.

Globalization has led to a drastic change on the international trade, this has caused that many countries such as France and Colombia find new business partners. This is the raison because I develop the investigation about How these countries can be integrated commercially in the dairy sector? Colombia and France had active trade relations for more than 8 years, but this has been declining for several factors. In the case of France, it has found that Germany is an excellent producer of raw milk, which can supply domestic demand and can export large quantities with a low price to European countries because of its proximity. For this reason, Colombia is a country that can not compete with Germany directly in raw milk, but I concluded that Colombia could become a major competitor with organic milk. This is the result of a research of the way they raise and feed the cows in the two countries, Colombia is generally on open country and Germany is on cow housing. In Colombia, the country found that Venezuela could offer many benefits in the processing of raw milk, and other processes that require high technology. But today Colombia has had several disputes with Venezuela and many Colombian companies are affected in this sector. Additionally, France is one of the largest producers and distributors of processed milk and its derivatives; it launches annually many manufactured products with high technology. At this point, Colombia can take out the best advantage because it can create an strategic alliance with French companies to bring most innovative and processed products such as cheese and yoghurts. The theoretical framework of this thesis consists on the analysis of competitiveness, because it is relevant to see if these two countries are competitive or if one has the comparative advantage over the other. The related authors are: Michael Porter, Adam Smith and David Ricardo. To complete the theoretical part, we found that France has a comparative advantage over Colombia in this sector thanks to its high technology, and Colombia is not currently competitive in the area of raw milk because the milk price is higher and the distance is a barrier, and it has no technology. But this research indicates that Colombia could become a competitive country selling organic milk.

This is volume II of my two-volume study of the nuclear strategies/strategy preferences of Britain, France and West Germany in the Cold War. It shows that the great variable is the mentalities, culture, and particular interpretations of particular historical experiences of these three countries. These mental frameworks are reconstructed, in the tradition of the French Annales/Mentalite schools (that in turn is rooted in anthropology) by looking at a very large nunber of public texts in the context of the public discourse about nuclear strategy in each country.

We analyze the potential of the Fermilab Tevatron and CERN Large Hadron Collider (LHC) to study anomalous quartic vector-boson interactions gamma gamma ZZ and gammaW(+)W(-). Working in the framework of SU(2)(L) circle times U(1)(Y) chiral Lagrangians, we study the production of photon pairs accompanied by l(+) l(-), l(+/-) v, and jet pairs to impose bounds on these new couplings, taking into account the unitarity constraints. We compare our findings with the indirect limits coming from precision electroweak measurements as well as with presently available direct searches at CERN LEPII. We show that the Tevatron run II can provide limits on these quartic limits which are of the same order of magnitude as the existing bounds from LEPII searches. LHC will be able to tighten considerably the direct constraints on these possible new interactions, leading to more stringent limits than the presently available indirect ones.

We perform a detailed analysis of the potentiality of the CERN Large Hadron Collider to study the single production of leptoquarks via pp→e±q→ leptoquark →e± q, with e± generated by the splitting of photons radiated by the protons. Working with the most general SU(2)L⊗U( 1 )Y invariant effective Lagrangian for scalar and vector leptoquarks, we analyze in detail the leptoquark signals and backgrounds that lead to a final state containing an e± and a hard jet with approximately balanced transverse momenta. Our results indicate that the LHC will be able to discover leptoquarks with masses up to 2-3 TeV, depending on their type, for Yukawa couplings of the order of the electromagnetic one.

We perform a detailed analyses of the CERN Large Hadron Collider (LHC) capability to discover first generation vector leptoquarks through their pair production. We study the leptoquark signals and backgrounds that give rise to final states containing a pair e+e- and jets. Our results show that the LHC will be able to discover vector leptoquarks with masses up to 1.8-2.3 TeV depending on their couplings to fermions and gluons. ©1999 The American Physical Society.

We estimate the cross sections for the production of resonances, pion pairs, and a central cluster of hadrons in peripheral heavy-ion collisions through two-photon and double-pomeron exchange, at energies that will be available at the Relativistic Heavy Ion Collider (RHIC) and the Large Hadron Collider (LHC). The effect of the impact parameter in the diffractive reactions is introduced, and by imposing the condition for realistic peripheral collisions we verify that in the case of very heavy ions the pomeron-pomeron contribution is indeed smaller than the electromagnetic one. However, they give a non-negligible background in the collision of light ions. This diffractive background will be more important at RHIC than at LHC.

We analyze double Higgs boson production at the Large Hadron Collider in the context of Little Higgs models. In double Higgs production, the diagrams involved are directly related to those that cause the cancellation of the quadratic divergence of the Higgs self-energy, providing a robust prediction for this class of models. We find that in extensions of this model with the inclusion of a so-called T-parity, there is a significant enhancement in the cross sections as compared to the Standard Model. © SISSA 2006.
