In this article visual technologies and their use in three reconstructions after an incident are linked with accountability issues. Conclusions are drawn on the relation between administration, the choice of technology to create and distribute visual occurrences, and society and how visualizations are used to frame accountability issues. 相似文献

In this paper, we study to what extent a movie’s box-office receipts are affected by the temporal distribution of rival films. We propose a reduced-form empirical model to measure and test competition effects among films released close to each other in a standard regression framework. Such an analysis is appealing in terms of its policy implication and may provide guidance to distributors to decide on their releasing dates of their firms. We estimate this model using information on the films released in five countries: the USA, the United Kingdom, Germany, France and Spain. The geographical dimension of our data set permits us to control for unobserved heterogeneity among films released using panel data techniques, which allows us to evaluate the individual and specific effects of each film. Thus we deal with one of the most relevant features of the movie market, namely the presence of highly differentiated products. 相似文献

Responding to a survey requires cognitive abilities similar to those for any other linguistic task. We argue that, when faced with a cognitively challenging task, individuals respond by simplifying the task, declining it, or performing it poorly. Using the 2003 Program for International Student Assessment (PISA 2003) data sets, we document that the extent of construct differentiation in students’ mathematics learning strategies is strongly associated with their level of mathematics achievement. Likewise, the higher the level of mathematics achievement, the lower is the probability of a non-response to the mathematics learning strategy questions. Finally, the higher the students’ level of mathematics achievement, the more varied were their responses to the learning strategies items. These associations were examined across 40 participating countries. 相似文献

Simple as the outflow clock principle may seem for the measurement of time, its translation into an accurate clock raises formidable technical and conceptual problems. An attempt is made here to reconstruct the Egyptians' consciousness of these problems, and the success of their solutions. 相似文献

Research that clearly demonstrates the negative effects of institutionalization, particularly for young children, has been critical for changing policy. However, actually putting science into action requires advocacy, persistence, and perseverance. Policy makers and advocates must be informed about the research and use it effectively. This paper proposes a number of key components for translating research into policy and programs: analyzing the situation, using evidence to build the case for action, developing policies, building program capacity in child welfare and early childhood development, creating a family‐based child welfare system, and developing a system of monitoring and accountability. Much of the knowledge in this paper comes from experiences, desk reviews, and case studies of successful practices. Research provides the basis, but moving research to practice depends on collaboration between researchers who understand the key policy perspectives and policy makers who understand the research. 相似文献
