The special issue aims at exploring, with an economic perspective, the interconnections between cultural participation, in all its expressions, and tourism organization and patterns with the purpose of understanding economic effects, emerging trends and policy implications. The expanding notion of the cultural consumption of tourists makes the definition of cultural tourism increasingly elusive. Empirical investigations of the relationships between cultural participation and cultural heritage and tourism offer interesting hints in many directions. This introduction briefly overviews the premise of this special issue, the literature and the several perspectives taken by the included articles. Aside from their cultural topics—general, intangible or temporary—these essays all tackle some important economic dimensions of tourism. We encourage cultural economists to invest more in these fascinating areas as more than just intellectual tourists. 相似文献

No matter one’s wealth or social position, all are subject to the threats of natural hazards. Be it fire, flood, hurricane,
earthquake, tornado, or drought, the reality of hazard risk is universal. In response, governments, non-profits, and the private
sector all support research to study hazards. Each has a common end in mind: to increase the resilience of vulnerable communities.
While this end goal is shared across hazards, the conception of how to get there can diverge considerably. The earthquake
and hurricane research endeavors in the US provide an illustrative contrast. The earthquake community sets out to increase
resilience through a research process that simultaneously promotes both high quality and usable – preparedness-focused - science.
In order to do so, the logic suggests that research must be collaborative, responsive, and transparent. Hurricane research,
by contrast, largely promotes high quality science – predictions - alone, and presumes that usability should flow from there.
This process is not collaborative, responsive, or transparent. Experience suggests, however, that the latter model – hurricane
research - does not prepare communities or decision makers to use the high quality science it has produced when a storm does
hit. The predictions are good, but they are not used effectively. Earthquake research, on the other hand, is developed through
a collaborative process that equips decision makers to know and use hazards research knowledge as soon as an earthquake hits.
The contrast between the two fields suggests that earthquake research is more likely to meet the end goal of resilience than
is hurricane research, and thus that communities might be more resilient to hurricanes were the model by which research is
funded and conducted to change. The earthquake research experience can provide lessons for this shift. This paper employs
the Public Value Mapping (PVM) framework to explore these two divergent public value logics, their end results, and opportunities
for improvement. 相似文献

ABSTRACTThe literature on momentum is still undecided, with mixed results whether momentum exists or is only perceived to exist (“hot hand fallacy”). We explore whether momentum exists by looking at cases in which a basketball player has three consecutive free throws. A free throw is a well-defined task executed in a stable environment, allegedly giving momentum optimal chances to occur. Taking 14 NBA seasons we collected over 4500 three-free-throw sets (triplets). We obtained the outcomes of the shots as well as some additional variables about the player and the game: the player’s average free-throw percentage, home or away, and the game score and the quarter when the free throws were attempted. We first analyse the hit rates in the three shots and then proceed to regression analysis that also controls for the abovementioned variables. We address several concerns raised in the literature. All comparisons and analyses yield the same conclusion that there is no evidence for momentum in the data. 相似文献
