This article is the third in a series reporting on the changes in attitudes and interests‐‐mainly with respect to physics‐of several hundred students as they proceed through the Danish upper secondary school (Gymnasium). It concentrates on the results of the final investigation which took place shortly before the students leave the school. 相似文献

Since the mid‐twentieth century, special exhibitions of art forgeries have appeared in many museums in the United States and Europe. These exhibitions have displayed artworks of many kinds, and have been structured around a variety of objectives and methodologies to engage the public. Fundamentally, they inform that public about an uncomfortable reality: that artistic deception is more common than they may think. The collective phenomenon of these forums displaying faux art has reached a point at which it is a topic worthy of study. This article draws upon representative examples of exhibitions of fake art to present an overview of their “what,” “why,” and “how” in light of commonalities and differences among them. It furthermore traces a loose historical pattern in these exhibitions that shows change over time as well as continuity. 相似文献

In this article, we build on Stigler and Becker’s (1977) “consumption capital theory” and propose a novel conceptualization of film quality for the analysis of motion picture franchises. Generally, this theory predicts that the utility consumers derive from a particular good or service increases with prior consumption. We test our theoretical conjectures by drawing on the population of sequels that were running in the US between 1992 and 2011. The empirical results point to the explanatory power of the proposed framework. Film executives may use our findings to improve the profitability of their sequel productions. From a theoretical point of view, consumption capital theory allows for a more refined analysis of sequel performance along different dimensions. Moreover, it may provide a fruitful basis for the analysis of other serial media content, including books, TV, music, and games. 相似文献
