The increasing interest aroused by more advanced forecasting techniques, together with the requirement for more accurate forecasts of tourismdemand at the destination level due to the constant growth of world tourism, has lead us to evaluate the forecasting performance of neural modelling relative to that of time seriesmethods at a regional level. Seasonality and volatility are important features of tourism data, which makes it a particularly favourable context in which to compare the forecasting performance of linear models to that of nonlinear alternative approaches. Pre-processed official statistical data of overnight stays and tourist arrivals fromall the different countries of origin to Catalonia from 2001 to 2009 is used in the study. When comparing the forecasting accuracy of the different techniques for different time horizons, autoregressive integrated moving average models outperform self-exciting threshold autoregressions and artificial neural network models, especially for shorter horizons. These results suggest that the there is a trade-off between the degree of pre-processing and the accuracy of the forecasts obtained with neural networks, which are more suitable in the presence of nonlinearity in the data. In spite of the significant differences between countries, which can be explained by different patterns of consumer behaviour,we also find that forecasts of tourist arrivals aremore accurate than forecasts of overnight stays.

Malgrat la important revifalla que en els darrers anys han experimentat els estudis històrics, entre els quals cal incloure els d"història de l"art, centrats en l"antic bisbat, l"antic terme i la ciutat mateixa de Tortosa, avui encara resulta relativament escàs el coneixement que tenim tant dels materials de la construcció com dels mestres que van construir en aquest territori durant les èpoques medieval i moderna.1 Aquest breu estudi, basat en un únic document,2 pretén ser, simplement, una petita aportació a la història de l"arquitectura setcentista tortosina, i pretén serho en els dos vessants esmentats abans: el dels materials de la construcció i el dels mestres.
