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

Rapid advances in technology have provided the potential to connect citizens to their surroundings in unprecedented ways. While many scholars examine different types of efficacy as a predictor of behavior (e.g., internal, external, and political), it is essential to examine how confident citizens feel in their ability to use the technology before understanding how they will use it politically. Research shows that perceived competence increases motivation, which is correlated with behavior. This study examined how traditional measures of efficacy and a new measure affect online political behaviors, concluding that technological efficacy is a reliable construct predicting online news use and expression.  相似文献

A great number of Central Asian wall paintings, archeological materials, architectural fragments, and textiles, as well as painting fragments on silk and paper, make up the so called Turfan Collection at the Asian Art Museum in Berlin. The largest part of the collection comes from the Kucha region, a very important cultural center in the third to ninth centuries. Between 1902 and 1914, four German expeditions traveled along the northern Silk Road. During these expeditions, wall paintings were detached from their original settings in Buddhist cave complexes. This paper reports a technical study of a wall painting, existing in eight fragments, from the Buddhist cave no. 40 (Ritterhöhle). Its original painted surface is soot blackened and largely illegible. Grünwedel, leader of the first and third expeditions, described the almost complete destruction of the rediscovered temple complex and evidence of fire damage. The aim of this case study is to identify the materials used for the wall paintings. Furthermore, soot deposits as well as materials from conservation interventions were of interest. Non-invasive analyses were preferred but a limited number of samples were taken to provide more precise information on the painting technique. By employing optical and scanning electron microscopy, energy dispersive X-ray spectroscopy, micro X-ray fluorescence spectroscopy, X-ray diffraction analysis, and Raman spectroscopy, a layer sequence of earthen render, a ground layer made of gypsum, and a paint layer containing a variety of inorganic pigments were identified.  相似文献

The current study tests the influence of threatening-mediated intergroup contact on intergroup relations. A 2 (Immigration: Threat, No-threat) × 2 (Ingroup Group Exemplar: Present, Absent)?+?1 (Control Condition) experimental design was used to examine both the direct and indirect influence of news exposure on attitudes toward immigration. The moderating role of previous local news consumption was also investigated. Results indicate that exposure to a threatening news story about immigration directly affected attitudes toward immigrants’ human rights, but not attitudes toward immigration policy. News exposure also indirectly influenced both types of immigration attitudes through feelings of intergroup anxiety, particularly for heavy news consumers. The discussion highlights the implications for both intergroup threat theory and cultivation research.  相似文献

This paper explores the awareness of the young German and Norwegian participants in the Youth Olympic Games (YOG) of the additional educational mission of this new event, implemented by the International Olympic Committee. Among the questions considered are whether the nature of the event contradicts its claimed intention to focus on both competition and education. Data were collected through a set of interviews with young German and Norwegian athletes at the Singapore YOG in the summer of 2010 and the Innsbruck YOG in the winter of 2012. The findings revealed (1) a focus on elite sport by athletes and their coaches, while the educational aims were considered secondary; (2) that it was problematic for the young participants to focus on education in a high-performance event. The overall conclusion was that the YOG have had only limited success in achieving the educational ambitions of the Olympic Movement.  相似文献
