Using Heavy Quark Spin Symmetry in Semileptonic BcB_c Decays

The form factors parameterizing the B_c semileptonic matrix elements can be related to a few invariant functions if the decoupling of the spin of the heavy quarks in B_c and in the mesons produced in the semileptonic decays is exploited. We compute the form factors as overlap integral of the meson wave-functions obtained using a QCD relativistic potential model, and give predictions for semileptonic and non-leptonic B_c decay modes. We also discuss possible experimental tests of the heavy quark spin symmetry in B_c decays.Comment: RevTex, 22 pages, 2 figure

Cultural diversity in the curriculum: perceptions and attitudes of Irish hospitality and tourism academics

Academics are facing significant challenges in preparing indigenous students for employment in the multicultural working environment of hospitality and tourism organisations. In dealing with the impact of the new skills and flexibilities demanded by increasing globalisation, the indigenous workforce needs to possess a multicultural perspective and the adaptive skills and mindsets to integrate more inclusively in diverse work settings. This article explores the nature of cultural diversity within the Irish hospitality and tourism workforce (in both Northern Ireland and the Republic of Ireland). An attempt is made to identify the challenges that hospitality and tourism educators face in implementing education for cultural diversity within the curriculum in order to prepare indigenous students (and indeed local industry staff) for employment within a multicultural workforce. The main themes analysed include: training requirements; educators' requirements; programme content and learning outcomes; assessment methods; and methods of programme delivery
