ABSTRACT: It is customary to employ surveys to evaluate government services. Race is cited frequently as a source of differences between people in the evaluation of government services. African-Americans are reported to be more critical of government services than others. However, a possible source of error reported in survey research is response bias due to what is commonly called the race-of-interviewer effect: black and white respondents giving different answers as a function of who asks the question. This note investigates, through an experimental design, whether response bias exists in mail surveys. Using two institutions, one historically black and one historically white, residents in a Southern community were asked to evaluate government's response to growth. As expected, initial results affirmed the importance of race. However, additional analysis revealed a more complex role for race. More importantly, the results indicated that citizens may, in fact, take into consideration who asks the question. 相似文献

Waste, duplication, and coordination are among the cornerstone concepts upon which the social policy of the New Federalism is being developed. The proposed Allied Services Act captures and reflects most elements of the Administration's emerging social policy. An analysis of the legislation, which is significant in that it begins to define a public responsibility for planning social welfare services, indicates several issues of concern to the planner. The legislation raises questions such as: the criteria for definition of planning area boundaries; the relationship between the quality of planning and the limits of present planning resources; the quality and availability of standards to assess services; the complex formulae by which federal, state, and local governments allocate and support services; the role of formal interest groups in the planning process; the vitality of existing private (voluntary) health and welfare planning agencies; and finally the substance of planning education. As it now stands, the legislation has more potential for improving the management of services in a narrow sense of the concept than for any significant planning for social welfare services on a systemwide basis. 相似文献
