This article looks at the shifting intricacies of British assessments of the Soviet IRBM threat to the United Kingdom during the 1950s. Based on JIC, Cabinet and Air Ministry records of the period, as well as political memoirs, it looks at the assessments in parallel with the development of the British Blue Streak nuclear ballistic missile programme. This land‐based weapon was eventually cancelled in April 1960 on strategic not cost grounds, too early in this author's opinion.  相似文献

Participants recruited from one Historically Black University (HBU) and two predominantly White higher-education institutions evaluated and decided simulated voting rights case summaries in which the plaintiff was either a racially-defined (African American) or a nonracially-defined (farmers) minority group. Contrary to social identity and social justice findings of an in-group bias, the present study showed greater support at all institutions for the voting rights of the African Americans than for the rural farmers, and the greatest support for both minority groups was found at the HBU. Perceived evidence strength was a better predictor of decisions than perceived unfairness, and both of these predictor variables completely mediated the effects of institution-type and involvement of a racially-defined group on decisions.  相似文献

This study assesses the impacts and implications for U.S. citiesof the set of congressional actions, presidential orders, andjudicial decisions which, together, comprise the so-called "devolutionrevolution." Based on a survey of chief administrative officersof all cities with a population over 100, 000, the study attemptsto assess the impacts of these various devolution policies.Although for a few local officials, devolution policies areseen as being effective; for most, these policies are viewedas having had very little significant policy or programmaticconsequences. The study identifies the characteristics of thosecities where local officials believe devolution policies are,and are not, having significant impacts and conclude that themost important long-term implications of devolution policiesmay be the impacts they are having, and will continue to have,on the changing political and administrative leadership skillsrequired in the urban arena.  相似文献

The application of supercritical fluid chromatography (SFC) in forensic science is reviewed. The applications centre on the analysis of explosives and of drugs of abuse. The systems employed are discussed in the context of comparison with gas chromatography and high-performance liquid chromatography methods which are traditionally used for such analyses. The advantages and disadvantages of SFC over these methods are discussed. Recommendations are made for the developments which are required in SFC technology if it is to find greater application in forensic science.  相似文献

Drought-induced inflation of cereal prices and the consequent turning of the terms of trade against livestock upset existing exchange entitlements and contributed to higher than normal mortality rates among the rural Beja populations in Red Sea Province in the early to mid-1980s. The Beja are agropastoralists who raise goats and sheep, and sow some sorghum. Their staples of consumption are goat milk and a prepared dish made with sorghum called asayda. They do not grow enough sorghum for household consumption, but they sell male goats in local markets in order to purchase sorghum. They also engage in a variety of minor activities to generate income for the purchase of sorghum.

In this article, data from two markets on cereal and livestock prices for the years 1980 to 1989 are examined. The objectives of the study were to examine market performance, especially that associated with the drought and famine in the mid-1980s in Red Sea Province, and to examine how the inflationary period from 1988 to 1990 differed from or resembled the early to mid-1980s.  相似文献
