The Drug Information Portal is a free Web resource from the National Library of Medicine (NLM) that provides a user-friendly gateway to current information for more than 15,000 drugs. The site guides users to related resources of NLM, the National Institutes of Health (NIH), and other government agencies. Current drug-related information regarding consumer health, clinical trials, AIDS, MeSH pharmacological actions, MEDLINE/PubMed biomedical literature, and physical properties and structure is easily retrieved by searching on a drug name. A varied selection of focused topics in medicine and drugs is also available from displayed subject headings. This column provides background information about the Drug Information Portal, as well as search basics.  相似文献

National security controls on information and communication in the United States arise from a variegated body of Executive Branch measures, statutes, and court decisions, as well as shifting opinions concerning the application of such authorities. After a discussion of the current national security atmosphere in the country, a brief history of Federal controls will be followed by an in-depth presentation of the current framework of controls on information and communication. Lastly, this review concludes with a discussion of the major implications of current conditions upon constitutional rights and democratic values in the United States.  相似文献

情景分析法是在环境非常复杂,不确定性非常高的情况下预见未来的一个重要方法.该方法在情报分析中的运用,虽然国内外都有一定的介绍,但这些介绍要么缺乏实际案例;要么案例过度简化令人很难理解.美国国家情报部门的案例国内尚未见到,该方法在美国情报部门日常情报工作中的运用模式还沒有人做过研究.本文通过对美国中央情报局最新解密的24份预见情报文件的梳理,总结了情景分析法在美国情报部门的运用,为我国企业和国家情报研究人员提供了"最佳实践"案例.本研究有助于我国情报工作者更好地借鉴国外的情报分析方法以及更好地保护我们自己的情报.  相似文献

Forbidden to censor, and saddled with an undefined (and perhaps undefinable) criterion of the “public interest, convenience and necessity”; for deciding among otherwise‐qualified applicants for a broadcast facility, it is little wonder that the FCC has relied upon a patchwork of precedents and rule‐of‐thumb standards. Possibly because of the uncertainty of these standards, and partly because the staff has not increased in size as greatly as has the workload, the Commission has avoided whenever possible the enlargement of license application hearings to include anyone other than the applicants themselves. Sometimes, however, the courts haven't allowed the FCC to so restrict the number of participants in a hearing, and sometimes the courts have had to remind the Commission that the laboriously accumulated body of administrative practice and precedent is not always the same as the language or purpose of the Communications Act of 1934.

“Economic injury”; is a station owner's concept. It is at the interface of theory and marketplace reality. It is the almost impossible‐to‐prove claim that the establishment of a new station in one's market will so split the available revenues that both stations will fail—or, at least, that both stations will have to operate with substandard (e.g., cheaper) programming, and thus will not serve the public interest. At first, the FCC listened to some of these claims, but soon evolved a policy of avoiding them, by whatever means and reasoning that it could. Over the years, and despite substantial prodding from the courts, the FCC's policy of avoiding this claim has become rigid . . . thus providing us with an excellent and fascinating case study of administrative policy formulation.  相似文献

Mapping the digital divide in America is a multifaceted issue; however, the influence of underlying socioeconomic causes, the shift in the conversation to new divides including broadband accessibility and digital literacy, and the importance of the library in narrowing the divide are all prominent points of focus in the literature today. As conversations surrounding the digital divide begin to shift from a divide in access to a divide in skills and/or literacy, attention must be drawn to meeting those needs in equal measure to maintaining access as the primary means of closing the digital divide in America.  相似文献

For over 40 years, the National Library of Medicine's (NLM) Toxicology and Environmental Health Information Program (TEHIP) has worked to organize and to provide access to an extensive array of environmental health and toxicology resources. During these years, the TEHIP program has evolved from a handful of databases developed primarily for researchers to a broad range of products and services that also serve industry, students, and the general public. TEHIP's resources include TOXNET , a collection of databases, including online handbooks, bibliographic references, information on the release of chemicals in the environment, and a chemical dictionary. TEHIP also produces several resources aimed towards the general public, such as the Household Products Database , which helps users explore chemicals often found in common household products, and Tox Town , an interactive guide to commonly encountered toxic substances, health, and the environment. This paper introduces some of NLM's environmental health and toxicology resources.  相似文献
