IR finite one-loop box scalar integral with massless internal lines

The IR finite one-loop box scalar integral with massless internal lines has been recalculated. The result is very compact, simple and valid for arbitrary values of the relevant kinematic variables. It is given in terms of only two dilogarithms and a few logarithms, all of very simple arguments.Comment: 7 pages, 2 figure

Dimensionally regulated one-loop box scalar integrals with massless internal lines

Using the Feynman parameter method, we have calculated in an elegant manner a set of one$-$loop box scalar integrals with massless internal lines, but containing 0, 1, 2, or 3 external massive lines. To treat IR divergences (both soft and collinear), the dimensional regularization method has been employed. The results for these integrals, which appear in the process of evaluating one$-$loop $(N\ge 5)-$point integrals and in subdiagrams in QCD loop calculations, have been obtained for arbitrary values of the relevant kinematic variables and presented in a simple and compact form.Comment: 14 pages, 2 figures included, SVJour, journal versio

Corporate social responsibility in tourism - The most popular tourism destinations in Croatia: Comparative analysis

In today\u27s rapidly changing tourism market, it is getting more and more difficult for a destination to be competitive on the global level. Hotel companies, as well as tour operators have a very important role in creating the tourism product. Tourism companies should be able to create the tourism product whilst operating in a responsible way. With the implementation of a socially responsible business practice, tourism companies contribute to the achievement of sustainable tourism and, consequently, to the achievement of sustainable development. The discussion about the importance of corporate social responsibility (CSR) in the tourism industry makes the very essence of this paper. The aim of the paper is to present and discuss the level of social and environmental sensitivity of managers of the highest category hotels in the Dubrovačko-Neretvanska, Istarska and Primorsko-Goranska counties. Results presented in this paper are based on the research conducted in the summer of 2008. The research was enriched with the analysis of the web sites of the selected companies in order to get an idea of whether the corporate social responsible practice has been somehow underlined. Results have shown that the practice of CSR has still not been widely recognized
