The relationship between culture and tourism has been widely investigated from different perspectives. A large strand of literature studies the role of cultural heritage to attract tourists, while a rich bulk of studies on cultural participation investigates the impact of tourism flows on the demand for culture. Another aspect worth investigating relates to the link between cultural participation and the performance of tourism destinations (TDs), as a higher cultural participation in an area could boost the performance in the management of tourism resources. However, so far, this issue has been disregarded in the literature, and this paper aims at filling this gap. Specifically, it studies the effect of cultural participation on TDs’ performance using a conditional efficiency approach that ensures robust inference on the role of environmental factors. We employ data on the Italian regions for the period 2004–2010, and we explore the role of cultural participation for tourism by using several indicators. Our findings offer empirical support to the positive role of cultural participation and, thus, suggest that public cultural policies might also boost the efficiency of the tourism sector. 相似文献

In the paper some case studies of damaged towers in Italy are presented: the Tower Masserano of Palace Ferrero - La Marmora at Biella, the bell tower of the Collegiata of San Vittore at Arcisate, and three medieval towers in Alba. A methodology is put forward for combining laboratory and nondestructive testing methods with monitoring systems in order to reach the goal of evaluating the state of conservation of historic towers and its evolution in time. 相似文献

Mercury porosimetry was applied to the study of pore structure of the historic Roman cement mortars representative of different locations in Europe and time periods as well as different application techniques from architectural castings to in situ formed renders and profiles. Three categories of pores were found to coexist in the mortars. The finest pores, with diameters below 0.1 μm, are present within the hardened aged Roman cement matrix. The larger ‘air’ pores, with diameters between 0.2–2 μm, are due to the evaporation of the excess unbound water and restricted hydration. Pores larger than 2 μm are rare and, in general, can be related to microcracking induced by shrinkage drying and mortar weathering. The mortars have rarely been found to develop a dense fine-porous microstructure characteristic of the ideal conditions of moist-curing; massive architectural castings being the only exception identified. The presence of larger ‘air’ pores was, in turn, almost universally observed. The investigations of the freshly prepared Roman cement mortars have revealed that the restricted hydration could be due to the exposure of the freshly laid surface to dry real-world external environments, a high water-to-cement ratio in the original mortars, or the drawing of water from the stucco mass due to insufficient pre-wetting of the porous masonry. The insufficient reactivity of historic cements, resulting from a high content of over-burned, non-reactive cement components or coarseness of the cement grains, could be another reason for yielding poorly hydrated mortars in the past. In general, Roman cement stuccoes are in an excellent state of preservation in spite of their usual exposure to polluted urban environments for more than a century. Therefore, the coexistence of Roman cement mortars of widely different pore structures has not brought about any problems of incompatibility which field observations could reveal. The Roman cement repair materials have been found to develop pore structures similar to those of historic mortars. Therefore, they are in broad terms compatible with historic masonry or stuccoes. However, the porosity and strength of the repair materials can be controlled by a careful manipulation of the water-to-cement ratio of the mix to adapt them better to the properties of the host material. 相似文献

The aim of the paper was to evaluate changes in muscle force-velocity parameters (F-v) in elderly women subjected to physical exercise. The examinations encompassed 20 women, aged 62–71, who were students at the University of the Third Age in Wroc?aw. The evaluation of flexors and extensors of the knee joint, as well as flexors and extensors of the spine within the lumbar part, was performed under isokinetic conditions. The assessment was conducted three times: first, a preliminary evaluation; second, after four months of rehabilitation, which included march training and systemic exercises; third, was performed after another 12 months, during which the patients were subjected to various forms of individually selected physical activity. The examinations of muscles affecting the knee joint revealed that the results achieved in the second measurement, performed with load of 60°/s, revealed higher values than in the first examination and were similar or higher in the third examination. With a load of 180°/s, values achieved in the second measurement were higher than results from the first measurement and were mostly lower than registered in the measurement. The highest values of parameters F-v for flexors and extensors of the lumbar part of the spine were registered in third examination. The results were about 20% higher than achieved within measurements 1 and 2. The increase and maintenance of muscular fitness in elderly women is possible only if a load applied exceeds threshold values and is applied for a long time. 相似文献

The vision behind the work of the gender equality advisors in Norwegian universities and the Research Council of Norway is that of full equality between women and men in all areas and at all levels of the sector of higher education. The Network of Gender Equality Advisors in Higher Education and Research was formed in 1994. Both good and less good news can be reported on the work accomplished so far. A double strategy is applied to tackle gender inequality: mainstreaming and special commitment. 相似文献

Category‐based induction is a hallmark of mature cognition; however, little is known about its origins. This study evaluated the hypothesis that category‐based induction is related to semantic development. Computational studies suggest that early on there is little differentiation among concepts, but learning and development lead to increased differentiation based on taxonomic relatedness. This study reports findings from a new task aimed to (a) examine this putative increase in semantic differentiation and (b) test whether individual differences in semantic differentiation are related to category‐based induction in 4‐ to 7‐year‐old children (N = 85). The results provide the first empirical evidence of an age‐related increase in differentiation of representations of animal concepts and suggest that category‐based induction is related to increased semantic differentiation. 相似文献
