Antropologia e Turismo: A importância da Antropologia nos Cursos Superiores de Turismo em Portugal

O turismo, na sua complexidade e multiplicidade, afecta as pessoas, os locais e a cultura de uma sociedade. A visão antropológica é insuficiente para compreender a riqueza e a diversidade do fenómeno turístico. No entanto, ela tem dado e continua a dar um contributo fundamental para a análise das práticas turísticas culturais em diferentes sociedades. O presente artigo pretende analisar a importância que a Antropologia assume nos planos curriculares dos Cursos Superiores de Turismo em Portugal.

Does final demand for energy in Portugal exhibit long memory

In this paper, we measure the degree of fractional integration in final energy demand in Portugal using an ARFIMA model with and without adjustments for seasonality. We consider aggregate energy demand as well as final demand for petroleum, electricity, coal, and natural gas. Our findings suggest the presence of long memory in all of the energy demand variables, that the series are stationary, although the mean reversion process will be slower than in the typical short run processes. These results have important implications for the design of energy policies. The effects of temporary policy shocks on final energy demand will tend to disappear slowly. This means that even transitory shocks have long lasting effects. Given the temporary nature of these effects, however, permanent effects require permanent policies. This is unlike what would be suggested by the more standard but much more limited unit root approach, which would incorrectly indicate that even transitory policies would have permanent effects.
