This work aims at assessing, by simulation methods, the performance of asymptotic confidence intervals for Zenga's new inequality measure. The results are compared with those obtained on Gini's measure, perhaps the most widely used index for measuring inequality in income and wealth distributions. Our findings show that the coverage accuracy and the size of the confidence intervals for the two measures are very similar in samples from economic size distributions.  相似文献

The notion of Equality of Opportunity (EO) has pervaded much of economic and social justice policy over the last half century in conveying a sense of liberation from the circumstances that constrain an individual’s ability to achieve it, and it has been a cornerstone of many gender equality programs. However unequivocal pursuit of the so called “Luck Egalitarianism” imperative has met with many critics who question why individuals who are blessed with good circumstances would wish to be “liberated” from them. This has led to a more qualified pursuit of Equal Opportunity which adds an additional proviso—that no circumstance group should be made worse off by such a policy or decentralized private initiative. Indeed observed practices, by focusing on the opportunities of the poorly endowed in circumstance, do accord with such a qualified Equal Opportunity mandate. Here it is contended that, because of the asymmetric nature of such a policy or initiative, existing empirical techniques will not fully capture the progress made toward an EO goal. Hence a new technique is introduced and employed in examining progress toward such a Qualified Equal Opportunity (QEO) Objective in the context of the educational attainments of Canadian males and females born between the 1920s and the 1970s (In the early part of that century, females did not perform as well as males educationally, and were much more constrained by their parental educational circumstance). A QEO goal is generally found to cohere with the data with females becoming less attached to their parental educational circumstance, and indeed surpassing males in their educational attainments.  相似文献

Numerous studies document the disadvantage in child health of the urban poor in African cities. This study uses Demographic and Health Survey data from 23 countries in sub-Saharan Africa to examine whether the urban poor experience comparable disadvantages in maternal health care. The results show that, although on average the urban poor receive better antenatal and delivery care than rural residents, the care of the urban poor is worse than that of the urban non-poor. This suggests that the urban bias in the allocation of health services in Africa does not benefit the urban poor as much as the non-poor. Multilevel analyses reveal significant variations in maternal health in urban areas across countries of sub-Saharan Africa. The dis-advantage of the urban poor is more pronounced in countries where maternal health care is relatively good. In these countries the urban poor tend to be even worse off than rural residents, suggesting that the urban poor have benefited least from improvements in maternal health care.  相似文献

This paper is a preliminary report on an ecological analysis of recent changes in the spatial distribution of socioeconomic strata within 363 Standard Metropolitan Statistical Areas (or substituted units) in the United States. The central hypothesis guiding the study is that certain population subgroups in and around the larger urban areas are shifting their residential locations in predictable directions. Changes in the distribution of educational classes between the central city (or cities) and their surrounding rings from 1950 to 1960 are traced by using census data. A special feature of the analysis is the inclusion of 163 "lquasi-metropolitan areas" centered on cities that had 25,000-50,000 inhabitants in 1960.The initial results indicate that residential redistribution according to "social class" is occurring in all these metropolitan areas and that the pattern of change varies systematically. Regional differences are pronounced, and, as prior research has suggested, age of the city and population size appear to be important factors. The percent of adults in the high school and college categories in the rings of older and larger metropolitan areas generally increased disproportionately compared to the central cities. A variety of patterns of change, however, occurred among the younger and smaller metropolitan areas.Subsequent analyses will include (a) alternative methods of controlling color and regional location, (b) other measures of the independent and dependent variables used here, and (c) a multivariate approach to the problem of identifying and assessing the explanatory power of additional independent variables (including population growth, the over-all rate of decentralization, annexation history, economic base, and the character of the ring). The extent as well as the direction of change will also be investigated. Finally, the feasibility of quantifying an "evolutionary sequence" in the distribution of social classes will also receive attention.  相似文献

This paper examines male-female differences in knowledge and attitudes towards traditional and modern methods of child spacing in Malawi, based on the survey on traditional methods of child spacing in Malawi which was conducted in 1988. The results show that most people in Malawi are knowledgeable about both traditional and modern methods of child spacing. In general more men than women report knowledge and practice of traditional methods. For modern methods, however, females are more knowledgeable than males of all the specific methods, with the exception of condoms. The greater knowledge by women of female-based modern contraceptives appears to be a manifestation of the exclusion of males from the family planning program. The high rates of knowledge do not translate into equivalent high rates of utilization for both modern and traditional methods of contraception. The study further demonstrates that, while women are involved in making decisions to use contraception, the proportion of men initiating such decisions is greater than that of women. This finding calls for family planning planners to think seriously about revising their target population to include men.  相似文献

Rural communities and well‐being: a good place to grow up?   总被引:1,自引:0,他引:1  
This study looks at young people's accounts of life in communities in rural northern Scotland, and considers in what ways affective and social aspects of community are bound up with well‐being, over and above young people's concerns for the future, rural youth transitions, and out‐migration. Interviews were held with 15–18 year‐olds in four study areas (16 groups, N=60+) and a parallel survey of 11–16 year‐olds was conducted in eight study areas (N=2400+). Themes to emerge from the interviews included: opportunities locally, the future and staying on, as well as local amenities and services; but older teenagers also spoke at length about their social lives, family and social networks, and their community, both as close‐knit and caring and as intrusive and controlling. Rural communities were seen as good places in childhood, but not necessarily for young people. In parallel with that, the survey data paints a picture where feelings of support, control, autonomy, and attachment were all associated with emotional well‐being. Importantly, links between emotional well‐being and practical, material concerns were outweighed by positive identifications of community as close‐knit and caring; and equally, by negative identifications as intrusive and constraining, where the latter was felt more strongly by young women. Certainly, beliefs about future employment and educational opportunities were also linked to well‐being, but that was over and above, and independently of, affective and social aspects of community life. Additionally, migration intentions were also bound up with sense of self and well‐being, and with feelings about community life; and links between thoughts about leaving and community life as controlling and constraining were, yet again, felt more strongly by young women. Thus, gender was a key dimension affecting young people's feelings about their communities with significant implications for well‐being, and out‐migration. The study illustrates the importance of understanding the experiences young people have of growing up in rural areas, and how they evaluate those experiences: particularly, how life in rural communities matters for young people's well‐being; and especially, for young women.  相似文献

The quest continues for a Code of Conduct embracing universal principles which will provide guidelines and norms for corporate decision making in our increasingly complex world of global business. The search continues to identify those criteria which will enable the corporate leadership, especially those engaged in international business to be more morally sensitive and to make better ethical decisions. This article will report on an ambitious initiative designed to achieve that goal: to develop through consultation and consensus new Guidelines for International Corporations.  相似文献

Application of Monte Carlo simulation methods to quantitative risk assessment are becoming increasingly popular. With this methodology, investigators have become concerned about correlations among input variables which might affect the resulting distribution of risk. We show that the choice of input distributions in these simulations likely has a larger effect on the resultant risk distribution than does the inclusion or exclusion of correlations. Previous investigators have studied the effect of correlated input variables for the addition of variables with any underlying distribution and for the product of lognormally distributed variables. The effects in the main part of the distribution are small unless the correlation and variances are large. We extend this work by considering addition, multiplication and division of two variables with assumed normal, lognormal, uniform and triangular distributions. For all possible pairwise combinations, we find that the effects of correlated input variables are similar to those observed for lognormal distributions, and thus relatively small overall. The effect of using different distributions, however, can be large.  相似文献

Most survey data on sexual activities are obtained via face-to-face interviews, which are prone to misreporting of socially unacceptable behaviors. Demographers have developed various private response methods to minimize social desirability bias and improve the quality of reporting; however, these methods often limit the complexity of information collected. We designed a life history calendar—the Relationship History Calendar (RHC)—to increase the scope of data collected on sexual relationships and behavior while enhancing their quality. The RHC records detailed, 10-year retrospective information on sexual relationship histories. The structure and interview procedure draw on qualitative techniques, which could reduce social desirability bias. We compare the quality of data collected with the RHC with a standard face-to-face survey instrument through a field experiment conducted among 1,275 youth in Kisumu, Kenya. The results suggest that the RHC reduces social desirability bias and improves reporting on multiple measures, including higher rates of abstinence among males and multiple recent sexual partnerships among females. The RHC fosters higher levels of rapport and respondent enjoyment, which appear to be the mechanisms through which social desirability bias is minimized. The RHC is an excellent alternative to private response methods and could potentially be adapted for large-scale surveys.  相似文献
