This article evaluates the impact of opposition originating at the national level on affirmative action policies in 13 Texas cities in the late 1980s and early 1990s. We find that increased national hostility to affirmative action in hiring and contracting has had little effect on the content and strength of affirmative action programs in Texas municipalities. In fact, most programs have been maintained or strengthened since the 1980s. However, there is no clear and consistent relationship between the strength of municipal programs and either minority political representation or the size of a city's minority population. City size appears to be a relevant, but not decisive, factor in maintaining comprehensive policies. As such, we explore two additional hypotheses—policy time lag and bureaucratic insulation—to account for the survival and strengthening of municipal affirmative action policies in the 1990s.  相似文献

The application of radiocarbon dating to archaeological samples generally requires calibration of 14C dates to calendar ages and interpretation of dating errors. In this paper, four recent methods of age calibration are assessed, particularly with regard to their quality of error treatment. Recent experimental research has suggested that commonly quoted errors on “raw” 14C dates may require enlargement to more realistic levels, which, when incorporated in the calibration schemes, produce a considerable increase in the size of the typical calibrated interval. A general decrease in the sensitivity of 14C dating using single, “normal precision” dates is implied. Thus typical calibrated age intervals range from 300 to 1300 years (approximate 95% confidence level), with little improvement resulting if “high precision” calibration systems are used to correct “normal precision” dates. Of the four methods considered here, that proposed by Neftel is found to provide the most objective, flexible, comprehensive and “easy to use” scheme. This method is particularly recommended for its treatment of errors both on the dates to be calibrated and on the calibration curve itself.  相似文献
