This study examines the relation between local news content and ownership structure in 17 television markets in the United States. It is an extension of the localism research that was conducted by the Federal Communications Commission (FCC) in 2004 and the Local Television News Media Project at the University of Delaware in 2007 (see FCC, 2007). The findings point to the need to consider television markets as the appropriate unit of analysis when examining the effect of ownership on local content. Ownership does matter in the production of news on local broadcasts. When examining only station-level factors, independent stations broadcast more local content on their newscasts than those stations that were either (a) owned-and-operated (O&O) and part of a duopoly, (b) O&O-only, or (c) part of a duopoly-only. However, when examining station-level and market-level factors of television markets, the station-level ownership profiles positively affected local content. Market-level factors that indicated more consolidation negatively affected the proportion of local news presented in the entire designated market area. 相似文献

ABSTRACTThe International Standard Serial Number (ISSN) has been the standard, eight-digit code used to identify newspapers, journals, magazines, and periodicals on all kinds of media—print and electronic—for the past 40 years. Periodically, the standard must be revised to allow it to accommodate new formats, changes in the publishing industry and information supply chain, and other developments in the information field. Regina Romano Reynolds, director of the U.S. ISSN Center at the Library of Congress, describes the issues that the ISSN International Centre perceives as necessitating a revision of the standard and the likely next steps in the International Organization for Standardization standards revision process. 相似文献

Step 6: does not routinely employ practices, procedures unsupported by scientific evidence: the coalition for improving maternity services: 下载免费PDF全文
Step 6 of the Ten Steps of Mother-Friendly Care addresses two issues: 1) the routine use of interventions (shaving, enemas, intravenous drips, withholding food and fluids, early rupture of membranes, and continuous electronic fetal monitoring; and 2) the optimal rates of induction, episiotomy, cesareans, and vaginal births after cesarean. Rationales for compliance and systematic reviews are presented. 相似文献

Internet use among pregnant women is common and frequent, while attendance at childbirth education classes appears to be on the decline. This article explores why women turn to the Internet in pregnancy and how Internet use may affect their knowledge, attitudes, and behaviors. It suggests strategies for engaging women's interest in the Internet and describes how doing so may help increase the effectiveness of "traditional" childbirth education while mitigating the potentially overwhelming and confusing aspects of Internet use. 相似文献
