The literature on public, educational, and government (PEG) access channels has focused on production rather than audience analysis, which hinders our understanding whether such channels remain relevant forums for public expression and a source of community information in an increasingly digitized and converging media landscape. To address this gap, this study draws on random sampled survey data in Austin, Texas to analyze the audience of PEG access channels. Findings suggest that public access television remains relevant for underprivileged populations, especially racial minorities and less educated people. Online media do not reduce the importance of cablecasting public access content to local residents. Compared to non-viewers, viewers of public access channels have significantly higher social capital. This research has practical implications because many PEG channels across America have been cut back or shut down due to budget cuts. 相似文献

对技术时代的人、经济与文化的关系,卢卡奇认为经济的优先性既是人的物化的表现,也是文化被扭曲的表现,但它仅限于阶级社会。经济统治的终结是真正文化产生的必要前提。真正的文化是把反映人的自由活动作为自身目的的文化,这样的文化对社会的经济基础保持着自己的自由。 相似文献

Screening for early reading problems is a critical step in early intervention and prevention of later reading difficulties. Evaluative frameworks for determining the utility of a screening process are presented in the literature but have not been applied to many screening measures currently in use in numerous schools across the nation. In this study, the accuracy of several Dynamic Indicators of Basic Early Literacy Skills (DIBELS) subtests in predicting which students were at risk for reading failure in first grade was examined in a sample of 12,055 students in Florida. Findings indicate that the DIBELS Nonsense Word Fluency, Initial Sound Fluency, and Phoneme Segmentation Fluency measures show poor diagnostic utility in predicting end of Grade 1 reading performance. DIBELS Oral Reading Fluency in fall of Grade 1 had higher classification accuracy than other DIBELS measures, but when compared to the classification accuracy obtained by assuming that no student had a disability, suggests the need to reevaluate the use of classification accuracy as a way to evaluate screening measures without discussion of base rates. Additionally, when cut scores on the screening tools were set to capture 90 percent of all students at risk for reading problems, a high number of false positives were identified. Finally, different cut scores were needed for different subgroups, such as English Language Learners. Implications for research and practice are discussed. 相似文献
