Although vast social and political changes over the past decades have opened many opportunities for women, many activists and academics maintain that women continue to face significant barriers to entry into positions of power and influence. The vast majority of American leaders are white and male, but the representation of women in the professions has begun to rise as more and more women enter the leadership ranks of various professions. This article provides a profile of women who currently hold positions of power in the United States—who they are, what sectors they represent, and how their opinions on social and political issues compare and contrast with one another. Analyzing data from the Study of Leadership Characteristics, a recently completed national survey of American elites, this article examines the structure and gender composition of elites in the United States, revealing patterns of both conflict and consensus among women elites. 相似文献

Many studies have considered the economic, social, and psychological effects of hurricanes, earthquakes, floods, tornadoes, and other natural disasters, but few have considered their demographic effects. In this paper we describe and evaluate a method for measuring the effects of Hurricane Andrew on the housing stock and population distribution in Dade County, Florida. Using information collected through sample surveys and from other data sources, we investigate the extent of housing damages, the number of people forced out of their homes, where they went, how long they stayed, and whether they returned to their prehurricane residences. We conclude that more than half the housing units in Dade County were damaged by Hurricane Andrew; that more than 353,000 people were forced to leave their homes, at least temporarily; and that almost 40,000 people left the county permanently as a direct result of the hurricane. We believe that this study will provide methodological guidance to analysts studying the demographic effects of other large-scale natural disasters. 相似文献

Empirical analysis of the motor carrier industry pre- and post-regulatory reform reveals that deregulation resulted in significant changes in firm production structure and lower real average costs. Translog cost functions for firms operating in 1977 and 1983 were estimated and compared for "other specialized commodity" carriers. Fitted average costs were computed from these functions. The results indicate significant differences in the cost functions and real costs that cannot be attributed to technological changes but rather suggest efficiency gains. The results also suggest that it is inappropriate to predict outcomes of deregulation using empirical analyses of firms in the regulated environment. 相似文献

A number of previous studies have called attention (typically ex post facto) to the finding that schizophrenics tend to have backgrounds with a particular type of status imbalance—their occupational level is lower than their years of education would seem to merit. The data from this study substantiated this finding. Moreover, we found that the greater the magnitude of this type of inconsistency, the higher the proportion of schizophrenia. Since schizophrenics were especially downwardly mobile, however, we tentatively concluded that this type of status inconsistency is not a “cause” of schizophrenia but rather a consequence of that illness. 相似文献

From 1979 to 1996, the Survey of Consumer Attitudes response rate remained roughly 70 percent. But number of calls to complete an interview and proportion of interviews requiring refusal conversion doubled. Using call-record histories, we explore what the consequences of lower response rates would have been if these additional efforts had not been undertaken. Both number of calls and initially cooperating (vs. initially refusing) are related to the Index of Consumer Sentiment (ICS), but only number of calls survives a control for demographic characteristics. We assess the impact of excluding respondents who required refusal conversion (which reduces the response rate 5-10 percentage points), respondents who required more than five calls to complete the interview (reducing the response rate about 25 percentage points), and those who required more than two calls (a reduction of about 50 percentage points). We found no effect of excluding any of these respondent groups on cross-sectional estimates of the ICS using monthly samples of hundreds of cases. For yearly estimates, based on thousands of cases, the exclusion of respondents who required more calls (though not of initial refusers) had an effect, but a very small one. One of the exclusions generally affected estimates of change over time in the ICS, irrespective of sample size. 相似文献

Migration is the most difficult component of state and local population growth to forecast accurately because it is more volatile than either births or deaths, and subject to much larger fluctuations within a short period of time. In addition, migration rates can be based on several different measures of migration and the base population. The choice of the appropriate base population has received little attention from demographic researchers, but can have a tremendous impact on population projections. In this article, I develop three different models for projecting migration, each using a different denominator for migration rates. Population projections for ten states are made, using identical data and cohort component techniques, except for the different formulations of migration rates. Differences among the three sets of projections are noted, and conclusions are drawn regarding their usefulness as forecasts of population growth. 相似文献

The relationship between socio-economicstatus and fertility among married women is examined, using data from the 1/1,000 sample from the 1960 United States Census of Population and the 1960 Growth of American Families Study. Both sets of data indicate that the negative relationship between socio-economic status and fertility is still prevalent but may reflect different patterns of child-spacing rather than completed fertility. Labor force participation among these women is found to be negatively related to the number of children ever born. To determine the degree of involvement in this type of non-familial role, the work index or proportion of one’s married life engaged in the labor force is developed. The work index is found to be a particularly sensitive measure of involvement in the worker role vis-a-vis their fertility. The working hypothesis of this study, that such non-familial activity has a different effect according to one’s socio-economic status, is borne out. Participation in the labor force results in a relatively larger reduction in the fertility of upper status women than for those of lower status. However, this relationship apparently holds true only for those women from rural backgrounds but not for those from large urban areas. 相似文献
