The Internet continues to grow as an information and entertainment medium. Internet growth has implications for the news industry. Twenty-four hour news networks such as CNN and MSNBC regularly encourage viewers of their television programs to visit their Web sites. While visiting news Web sites, visitors are invited to participate in opinion polls. Unfortunately, these online opinion polls are not scientific and have little real news value. In spite of these limitations, news Web sites' Internet polls are often treated as serious topics in broadcast news discussions. This article examines media organizations' Internet online polls and critiques them as instances of symbolic representation and pseudo-events that have arisen largely out of the integration of print, broadcast, and Internet media. 相似文献

Informed learning is a pedagogy that focuses on learning subject content through engaging with academic or professional information practices. Adopting the position that more powerful learning is achieved where students are taught how to use information and subject content simultaneously, the research reported here investigated an informed learning lesson. Using phenomenographic methods, students' experiences of the lesson were compared with observations of how the lesson was enacted in the classroom. Based on an analysis of student interviews using variation theory, different ways of experiencing the informed learning lesson emerged. Some students understood the lesson to be about learning to use information, i.e., researching and writing an academic paper, while others understood it as focusing on understanding both subject content and information use simultaneously. Although the results of this study are highly contextualized, the findings suggest criteria to consider when designing informed learning lessons. 相似文献

The mushroom growth of radio and television instruction taking place since the end of World War II has left in its wake a patch‐work guilt of academic programs in colleges and universities from coast to coast. The importance of trying to answer the question ‘Where are we going?”; indicates a need for realistic stock‐taking and thorough curriculum evaluation. In keeping with its policy of seeking to advance the field of knowledge as to education for broadcasting, the Journal presents a special report on the current state of the curriculum which, it is hoped, will prove of value to all those interested in education for broadcasting. 相似文献

This study advances documentary film effects research by comparing the influence of a political documentary with a historical reenactment film on narrative engagement, affect, learning, and interest. Using the Rwandan genocide as a context of study, a documentary film, The Triumph of Evil, and the historical reenactment fictional film, Hotel Rwanda, were examined. Results revealed significant differences between documentary and historical reenactment film exposure for affective responses and issue knowledge gain. However, increased issue interest and narrative engagement were not significantly different for the two stimulus groups, suggesting that dramatic fictional reenactments of socio-political events lead to increased issue interest as much or more than the live footage and factual account of events offered in a documentary. The results of this study are discussed in terms of their importance for key democratic outcome variables (e.g., knowledge and participation), along with suggestions for future documentary film research. 相似文献

This article concludes work started for a presentation on bibliophile Andrei Avinoff made at a symposium on Russian art and Russian studies in America in 2008 and for the 2009 book Treasures into Tractors. A member of the pre-Revolutionary Russian aristocracy, Andrei Avinoff, emigrated to Pittsburgh, Pennsylvania and managed to collect imperial association books and books on Russian art from some of the same dealers—Simeon Bolan and Israel Perlstein—who were supplying large research institutions such as the New York Public Library, the Library of Congress, and Harvard University Library with the same material. 相似文献

This essay and checklist document the exhibition Pageant of the Tsars: The Romanov Coronation Albums, held at Hillwood Estate, Museum & Gardens February 16–June 8, 2013. The exhibition focused on the history of the Romanovs through the lens of the coronation albums of the tsars. Based on the collection of five of the seven coronation albums held in the Hillwood library, the exhibition was supplemented with objects from the museum and library collections, loans from other institutions, and electronic versions of the albums available on iPads in the exhibition and via the iBooks store. The show marked the 400th anniversary of the founding of the Romanov dynasty in 1613. 相似文献

Camera techniques are typically used in the study of human movement. However, as the number of joints and markers involved
in a study increases, data extraction and calculation become increasingly tedious and complicated. To overcome this challenge,
we propose a method of study that simplifies data extraction and calculation by using an electrogoniometer and dual Euler
angles. The contribution of the rotation of each arm segment to produce a racket head’s speed was identified in the context
of a badminton smash. The contribution of each segment rotation was computed using dual velocity analysis. A set of orthogonal
Cartesian frames was established for computing the anatomical rotational velocities for each of the three segments of the
upper arm. Electrogoniometers were attached to the subjects during the execution of the smash to obtain measurements of joint
angles throughout the motion. To test the algorithm, the calculated velocity of the racket head was compared to the measured
velocity. The calculated velocity was derived from an algorithm, while the measured velocity was obtained from a video image.
The results are similar, indicating that the dual velocity method is suitable for determining segmental velocities in such
kinematic situations. 相似文献
