Davies A 《Long Range Planning》1991,24(2):94-100
Although the planning operation is regarded by some observers as unrealistic in conditions of rapid change and increasing competition, the discipline of strategic thinking and the need for strategic leadership continue to be of vital importance. The author examines the purpose of the Board of Directors and its role in the management of strategy. 相似文献

Polls do not simply measure public opinion; they also providevital information that the public can use to form opinions andto make decisions. Using multiple regression analysis, the authorsfound that published polls had a powerful impact on the valueof the Canadian dollar during the 1988 Canadian federal election.This appears to have been due to the unprecedented importanceof economic issues in the federal campaign, the distinctivepositions taken by the major political parties with respectto the U.S.-Canadian Free Trade Agreement, and to the proliferationof "horse-race" polls in the media. These results have implicationsfor understanding the behavior of other elite groups, such asfinancial contributors and volunteer campaign workers, who mayalso use published horse-race polls to handicap election outcomes. 相似文献

Recent trends in the process of stratification 总被引:1,自引:0,他引:1
Using the 14 annual cross-sections from the General Social Survey, we specify a "basic model" of attainment and describe the year-by-year fluctuations in its parameters. The results are partially consistent with theories describing the gradual growth of universalistic patterns of stratification and mobility. Under a linear model of educational achievement, we find that the direct effects of race are weakening and the returns to class-based advantages are declining in tandem. The contours of the socioeconomic "gender gap" are also changing in important ways, with the male intercept declining at a rapid pace and the female term registering small and insignificant year-by-year gains. At the same time, the returns to experience and schooling are increasing for men, whereas the corresponding returns for women have remained stable over the 15-year period. This pattern of interaction effects implies that the size of the gender gap varies over time and across different population groups. 相似文献

"Two models, the U.S. census model and the latent-class model, are compared in their application to evaluating measurements of ethnicity. Although the census approach assumes that the response categories of a questionnaire item correspond to groups in the population, the latent-class approach seeks to assess whether any set of response categories can represent observed ethnic heterogeneity. Data collected using the 1990 census Hispanic-origin question and other instruments for measuring ethnicity suggest that the latent-class approach is superior whenever the response categories are not known to be valid. In particular, using the latent-class model, this article rejects the census model's assumption of a single dimension of meaning underlying responses to the Hispanic-origin question." 相似文献

Although survey researchers are often warned against using prestigenames in questions (e.g., identifying Contra aid as "PresidentReagan's policy"), prestige names are still commonly used. Tolearn more about the effects of using prestige names, we analyzetwo sets of experiments—on judicial confirmation electionsand on an initiative on tax indexing. The results indicate thatprestige names do more than shift responses in one direction—they eliminate the effect of education on DKs and provide moreof a political basis for the responses. 相似文献

Using data from the 1976 and 1988 censuses, the author notes that the population of Senegal has grown by 37.6 percent over the period and that this growth is concentrated in urban areas. One feature of this trend has been the growing primacy of the capital Dakar and a decline in the relative importance of smaller towns. The need to discourage rural-urban migration by promoting socioeconomic development in rural areas is stressed. (SUMMARY IN ENG) 相似文献
