Because advertising is the bread‐and‐butter of broadcasting in the United States, any attempt to limit the number and length of commercials is, bound to meet with strong opposition. One such unsuccessful attempt was made by the FCC only four years ago, but already memories of the events and maneuverings that swirled around this proposal are fading. Lawrence D. Longley investigated this topic in connection with his doctoral dissertation on “The Politics of Broadcasting” which is nearing completion at Vanderbilt University. Mr. Longley is instructor in the Department of Government at Lawrence University, Appleton, Wisconsin. 相似文献

The present research combines in-depth interviews and in-home observations to explore usage patterns and perceptions of television viewers in digital video recorder (DVR) households. Innovativeness, Use Diffusion, and Continuity-Discontinuity are employed to characterize DVR use and conceptualize DVR viewing in the home. Findings indicate that the DVR is an important, interactive technology that can help transform the way television is used by some consumers in their movement to proactive media decision makers. 相似文献

The caution with which the broadcaster views editorializing is interesting, when considered in light of the broadcaster's willingness to allow “strangers” (people not associated with station or network ownership) to comment on topics of the day. Today, the commentary is undergoing change in form and personnel, but it remains an important program type. Dr. Smith is Instructor in the Department of Speech at Bowling Green (Ohio) State University. 相似文献

Difficulties in indexing the degree of motivation or attention to television by people in the same room with a “live” television set have long been recognized. One element of this problem has been the question of determining which member of the household actually makes the selection of specific program or channel, and whether there are differences between types of households or socio‐economic classes that are related to different patterns of channel or program selection. 相似文献

In an attempt to reduce the educational achievement gap of Hispanic students in a professional degree program, two courses grounded in the Keller method were implemented at a pharmacy school. The Keller method is characterized by breaking course content into modules, then allowing students to test and repeatedly remediate and retest until competency is achieved. Outcomes from this intervention-based cohort study suggest that the Keller method is effective in reducing the educational achievement gap of Hispanic students in a professional degree program. 相似文献

This study compares the Rasch item fit approach for detecting multidimensionality in response data with principal component analysis without rotation using simulated data. The data in this study were simulated to represent varying degrees of multidimensionality and varying proportions of items representing each dimension. Because the requirement of unidimensionality is necessary to preserve the desirable measurement properties of Rasch models, useful ways of testing this requirement must be developed. The results of the analyses indicate that both the principal component approach and the Rasch item fit approach work in a variety of multidimensional data structures. However, each technique is unable to detect multidimensionality in certain combinations of the level of correlation between the two variables and the proportion of items loading on the two factors. In cases where the intention is to create a unidimensional structure, one would expect few items to load on the second factor and the correlation between the factors to be high. The Rasch item fit approach detects dimensionality more accurately in these situations. 相似文献

This study investigated how self-regulation contributes to the development of reading competence in an at-risk sample of 157 children born to adolescent mothers. It was hypothesized that reading readiness at age 5 would shape self-regulation at age 10, which in turn would influence reading competence at age 14. Based on structural equation modeling, it was concluded that self-regulation partially mediated the relationship between early reading skills and later reading competence. These findings suggest the importance of socioemotional and cognitive self-regulation in the development of reading competence; implications for classroom practice are discussed. 相似文献

Noise appears to critique the prevailing cognitive and social habits of modernity by providing concrete and particular art objects that demand attention and jar us from one‐dimensional life. Noise sounds, for a moment, like a true alternative not only to contemporary music but to a whole way of thinking through abstract generalisation and living through commercial mediation. Understood in this way, noise makes sense. Once noise is no longer inscrutable, however, it is assimilated into popular culture and becomes a commercial novelty. The blatant contradiction of the commodification of noise gives rise to a second order of critique wherein noise parades its uselessness and occasions reflection on the tortured existence of art in modernity, the ubiquity of identity thinking, and the relation between use and exchange value. This ironic endgame for noise, however, is itself absorbed by consumer culture and noise lives on as but another cool, extreme product. The cultural reception of noise thereby demonstrates the mechanism by which modernity absorbs artistic attempts to critique it, and noise is ultimately understood as a desperate but spectacular failure. 相似文献

We analyse 446 location decisions of R&D activities by multinational firms incorporated in the European Union over 1999–2006. Our results suggest that on average, the location probability of a representative R&D foreign affiliate increased with agglomeration economies from foreign R&D activities, human capital, proximity to centres of research excellence and the research and innovation capacity of the region. Further, our evidence suggests that in comparison to European multinational firms, the effects of patents intensity and proximity to centres of research excellence were stronger in the case of North American multinational firms. While government R&D expenditure intensity increased the probability of location of R&D activities by European multinational firms in the region, it did not have a significant effect on the probability of location of R&D activities by North American multinational firms. 相似文献
