Data were collected on rate per minute of administering token reinforcement for one male and six female teachers enrolled in a behavior modification course. Data were obtained from record cards maintained by pupils for tokens received during an observer-present condition and for an observer-absent condition. Comparison of reinforcement rates for observer-present vs. absent indicated significantly higher rates of token delivery (p <.025) in the observer-present condition. The observer effect has important implications for those programs in which assessment procedures introduce an observer into the classroom to collect data on changes in teacher behavior. 相似文献

The purpose of this study was to explore the intermedia influence of the Internet on traditional news media. Accordingly, this study examined the influence of Internet bulletin boards on newspaper coverage of the 2000 general election in South Korea at both first and second levels of agenda-setting through content analyses of major newspapers and the Internet bulletin boards during the campaign. Results of cross-lagged correlation analyses showed that newspapers influenced Internet bulletin boards at the first level of agenda-setting. Additionally, at the second level of agenda-setting, the influence of Internet bulletin boards on newspapers was found. Although reciprocity appeared in a few time spans, the results imply that the Internet funnels and leads public opinion as well as affecting the coverage of other media. 相似文献

During the past several years the Online Computer Library Center (OCLC) noted increasing concern from the library community regarding the future of cataloging. In response to this concern and to the rapidly changing metadata environment, OCLC is taking steps to further a paradigm shift toward early acquisition of metadata in WorldCat directly from the entities responsible for content purchased by libraries—chiefly the publisher supply chain. This shift in thinking requires the acknowledgement that metadata is dynamic and will change over time and relies upon the automated capture of metadata early in the publishing cycle as well as automated processes to help make the early metadata “good enough.” 相似文献

While scholars have increasingly engaged with the (micro)political and emotional experiences of coaches in professional and semi-professional football, little attention has been given to grass-roots coaches’ understandings of these issues. The aim of this paper is to outline one possible research agenda that could contribute to the development of a rich and increasingly nuanced understanding of the everyday realities of being a grass-roots football coach. In particular, we consider (volunteer) coaches’ participation in grass-roots football to be an inherently relational endeavour. Following the presentation of a creative fiction that is based upon our shared experiences of being grass-roots football coaches, we then illustrate how relational thinking might be productively applied to exploring the social, (micro)political and emotional features of grass-roots football coaching. 相似文献

This study replicates and extends Yates and Chapman's [(2007), Behavioral & Social Sciences Librarian, 26(1), 39–51] study of references from Communication Monographs, Communication Research, and Journal of Communication for the years 2010 and 2015 to draw further conclusions on the use of monographs in journal literature in the field of communication. Results show that the use of monographs in these journals has been outpaced by references to journal articles by a ratio of 5 to 1. The references were further analyzed by date and publisher. The authors then selected a random sample of the monographs cited in the journals to explore the availability of these monographs in electronic format and found that many are available as ebooks, particularly the more recent titles. The authors also examined the references from a collection of scholarly books in communication from 2005, 2010, and 2015 and found that the use of monographs may be declining slightly. The most notable trend in these references was the increase in the number of references to items in other formats such as film, television, comic books, and websites. The authors conclude that the monographs crisis is indeed affecting citation patterns in the field of communication. 相似文献
