The United States Census Bureau Library, acting on a study commissioned in 2002, has undertaken to improve electronic access for their patrons. The library provides e-journal and database access. The staff relies on usage statistics from these resources to sharpen the focus of the collection. Through an aggressive outreach program Census Bureau employees learn about these new products and services. Future plans include adding more e-journals, an open OPAC, and a new library building.  相似文献

"The census of population represents a rich source of social data. Other countries have released samples of anonymized records from their censuses to the research community for secondary analysis. So far this has not been done in Britain. The areas of research which might be expected to benefit from such microdata are outlined, and support is drawn from considering experience overseas. However, it is essential to protect the confidentiality of the data. The paper therefore considers the risks, both real and perceived, of identification of individuals from census microdata. The conclusion of the paper is that the potential benefits from census microdata are large and that the risks in terms of disclosure are very small. The authors therefore argue that the Office of Population Censuses and Surveys and the General Register Office of Scotland should release samples of anonymized records from the 1991 census for secondary analysis."  相似文献

Two key questions are addressed in this article. (i) Have Malawi's tobacco‐policy reforms led to improvements in the absolute prices that smallholders get? (ii) How do the prices that smallholders receive compare with what the rich estate owners get? Empirical results indicate that the reforms have led to some improvements in both absolute and relative prices that smallholder farmers receive. Major positive changes in the tobacco price‐structure have occurred after removing monopsony and liberalising the market. However, farmers, especially smallholders, are still faced with high transaction and logistics costs that need to be addressed.  相似文献

This article considers the influence of the ‘visual turn’ in diverse academic literature on the media representation of conflict. Primarily drawing on examples from American and British scholarship, the article presents encouraging evidence that the visualisation of conflict in news media is finally getting the kind of sustained theoretical scrutiny and rigorous empirical analysis that it deserves. Authors from varied disciplinary fields of research, from security studies to visual culture, are now engaging in a range of analytical and empirical investigations into the purportedly powerful roles of mediated visual imagery during wartime, employing conceptual tools such as ‘mediatisation’ and ‘performativity’. This article offers a summation of some of the key approaches: their intersections, distinctions and usefulness; while suggesting trajectories for further critical research into media visualisation of conflict.  相似文献

Image Restoration Discourse, Situational Crisis Communication Theory, and related crisis-response models tend to involve charges leveled at entities: individuals or organizations. In The New Rhetoric, Perelman and Olbrechts-Tyteca suggest an important mid-ground: stakeholder concerns regarding aberrant actions of a member of a larger public. Perelman and Olbrechts-Tyteca's “techniques of severance and restraint” comprise 11 strategies for countering the possible effects of an aberrant member's acts on the image and reputation of a larger public. This article will explore those techniques through an examination of how the National Review Online, the Web site complement of National Review magazine, responded to columnist Christopher Buckley's endorsement of Barack Obama in the 2008 U.S. presidential election.  相似文献

This article examines whether social class differences influences low-income, married and cohabiting African Americans to realize that they are in a “coupled” relationship. To determine the extent to which social class influences the assessment of “couple” status in these partnerships, we examined the qualitative responses of 30 cohabiting and 31 married African Americans to a question regarding the specific event in their relationship that made them realize they were a couple. Qualitative analyses of the data resulted in four delineated themes: (1) relationship marker, (2) affection/sex, (3) having or rearing children, and (4) time and money. Supporting qualitative data are presented in connection with each theme. The sociological aspects of income on African American romantic relationships are also discussed.  相似文献
