Now there are almost 800 publications, 100TV and 302 FM radio stations, 6 telecommunication companies, tens of news agencies, more than 44 licensed ISPs internet provider companies and several number of production groups are busy to broadcast information, drama serial, films according to the afghan Culture, and also connected the people with each other on national and international level. Afghanistan is a nation of 30 million people, and a majority live in its 37,000 villages. But low literacy rate (38.2%) is the main obstacle in Afghanistan, most of the people who lived in rural area are not educated and they are only have focus on radio and TV broadcasting. So, the main purpose of this study is the rapid growth of media in Afghanistan after the Taliban regime, but most of those have uncertain future.

  • Mapping the Information Environment in the Pacific Island Countries: Disruptors, Deficits, and Decisions
    December 2019 Mapping the Information Environment in the Pacific Island Countries: Disruptors, Deficits, and Decisions Lauren Dickey, Erica Downs, Andrew Taffer, and Heidi Holz with Drew Thompson, S. Bilal Hyder, Ryan Loomis, and Anthony Miller Maps and graphics created by Sue N. Mercer, Sharay Bennett, and Michele Deisbeck Approved for Public Release: distribution unlimited. IRM-2019-U-019755-Final Abstract This report provides a general map of the information environment of the Pacific Island Countries (PICs). The focus of the report is on the information environment—that is, the aggregate of individuals, organizations, and systems that shape public opinion through the dissemination of news and information—in the PICs. In this report, we provide a current understanding of how these countries and their respective populaces consume information. We map the general characteristics of the information environment in the region, highlighting trends that make the dissemination and consumption of information in the PICs particularly dynamic. We identify three factors that contribute to the dynamism of the regional information environment: disruptors, deficits, and domestic decisions. Collectively, these factors also create new opportunities for foreign actors to influence or shape the domestic information space in the PICs. This report concludes with recommendations for traditional partners and the PICs to support the positive evolution of the information environment. This document contains the best opinion of CNA at the time of issue. It does not necessarily represent the opinion of the sponsor or client.

PUB TYPE Speeches/Conference Papers (150) Reports - Research /Technical (143) EDRS PRICE MF01/PCO2 Plus Postage. DESCRIPTORS *Broadcast Industry; Foreign Countries; Intercultural Communication; Mass Media; *Media Research; *News Reporting; *Programing (Broadcast); *Radio; Telecommunications IDENTIFIERS *International Broadcasting; News Sources; *Pacific Islands ABSTRACT A study examined the diversity of news and cultural programing sources available to the Pacific Islands news media from international broadcasting and from related activities of countries outside the region. Questionnaires dealing with the use of international broadcast programs in the Pacific Islands radio services, how managers view listener interest in news and other countries, translation, and monitoring were developed and sent to all Pacific Islands broadcasting services, as well as those international services indicating that their signal could reach the Pacific Islands. Among the conclusions suggested by the data are that (1) island broadcast services make heavy use of international broadcasting for world news, (2) Radio Australia is the leading international broadcaster in the Pacific, and (3) international broadcasting is clearly an important pa-'t of Island broadcasting.

These emissions, if prop- erly characterized, enable the prompt and accurate detection of explosive threats. The following dissertation develops and evaluates techniques for detecting and locat- ing common electronic initiators. The unintended emissions of radio receivers and microcontrollers are analyzed. These emissions are low-power radio signals that result from the device's normal operation.
