Internet in the intermediation role of travel agents: The Portuguese case

This article attempts to assess the impact that Internet has in the intermediation of travel agencies operating in Portugal. Firstly, the study discusses theoretical concepts related to the topic such as: tourism, internet, characterization of tourism distribution, disintermediation, reintermediation and new integrated management systems for travel agents. Then, a questionnaire was developed which resulted in 125 valid responses. The data analysis showed that travel agencies are committed to a new type of intermediation based on new technologies, using new technology platforms to distribute their tourism products and services and to adopt new business models. The study concludes that, only this way, organisations will achieve sustainable growth.info:eu-repo/semantics/acceptedVersio

I love you… but not unconditionally: Perceptions about luxury fashion brands

The Generation Y (1978-2000) live in a constant change and are always interacting among them and the brands that they love. The current study aims to contribute to better understand the perceptions that Y's have about Corporate Social Responsibility in fashion luxury brands. Therefore, 31 in-depth interviews were conducted with a group of people belonging to Generation Y. The findings reveal that Y's are concerned about transparent procedures and helping business and society to improve as a consequence of their sustainable and responsible attitudes. The environmental issues and labour practices are the most cited, commented and recommended factors of corporate social responsibility (CSR) proposed by participants. The article provides a framework presenting the seven core factors to incorporate CSR.info:eu-repo/semantics/acceptedVersio

Search for direct production of charginos and neutralinos in events with three leptons and missing transverse momentum in √s = 7 TeV pp collisions with the ATLAS detector

A search for the direct production of charginos and neutralinos in final states with three electrons or muons and missing transverse momentum is presented. The analysis is based on 4.7 fb−1 of proton–proton collision data delivered by the Large Hadron Collider and recorded with the ATLAS detector. Observations are consistent with Standard Model expectations in three signal regions that are either depleted or enriched in Z-boson decays. Upper limits at 95% confidence level are set in R-parity conserving phenomenological minimal supersymmetric models and in simplified models, significantly extending previous results

Jet size dependence of single jet suppression in lead-lead collisions at sqrt(s(NN)) = 2.76 TeV with the ATLAS detector at the LHC

Measurements of inclusive jet suppression in heavy ion collisions at the LHC provide direct sensitivity to the physics of jet quenching. In a sample of lead-lead collisions at sqrt(s) = 2.76 TeV corresponding to an integrated luminosity of approximately 7 inverse microbarns, ATLAS has measured jets with a calorimeter over the pseudorapidity interval |eta| < 2.1 and over the transverse momentum range 38 < pT < 210 GeV. Jets were reconstructed using the anti-kt algorithm with values for the distance parameter that determines the nominal jet radius of R = 0.2, 0.3, 0.4 and 0.5. The centrality dependence of the jet yield is characterized by the jet "central-to-peripheral ratio," Rcp. Jet production is found to be suppressed by approximately a factor of two in the 10% most central collisions relative to peripheral collisions. Rcp varies smoothly with centrality as characterized by the number of participating nucleons. The observed suppression is only weakly dependent on jet radius and transverse momentum. These results provide the first direct measurement of inclusive jet suppression in heavy ion collisions and complement previous measurements of dijet transverse energy imbalance at the LHC.Comment: 15 pages plus author list (30 pages total), 8 figures, 2 tables, submitted to Physics Letters B.
