Large scale immigration to the United States and a sluggish national economy have brought to the forefront of the current immigration policy debate, the question of whether immigrants fully pay—in the form of taxes—for the public services they use. Recent estimates of the costs of immigration differ so widely that they have confused rather than enlightened that debate. This paper argues that a uniform accounting framework must be agreed to if future studies are to provide credible and reliable estimates of costs and benefits upon which immigration policy can be formulated. The key conceptual, factual, and accounting issues that are to be addressed for the development of such a framework are outlined.  相似文献

In this paper I investigate the use of a measure of well-being derived from time-use data on the enjoyment of activities, and explore the association between the well-being of partners. The measure of well-being used is directly derived from the subjective assessment of the enjoyment of activities as recorded in time-use diaries. It is shown that this measure yeilds plausible results which share many of the characteristics of other measures of well-being. In addition, since the diaries used in the analysis were collected from couples it has also been possible to investigate the association between the well-being of partners. It is shown that in multivariate analyses including both time-use and socio-demographic variables the effect of a partner's well-being has by far the most significant impact on individual well-being. It is argued that this combination of information offers a useful means of analysing the relationship between time-use, well-being and the couple relationship. In this sense the analysis cross-cuts some of the conventional disciplinary boundaries which have served to separate the study of emotional relationships and psychological states from that of the daily activities of households.  相似文献

The advance of life expectancy within high‐income countries from 1955 to 1996 is well represented by a straight‐line trend. This explains more of the variance on average, and in 19 of 21 high‐income countries, than logged or unlogged age‐standardized death rates. Change in life expectancy in individual countries over this period was partially predicted by a country's level relative to the rest of this group of high‐income countries and partially by a country's own prior rate of advance, with substantial convergence toward the group mean for both measures.  相似文献

This paper reviews the research on the measurement and prediction of subjective well-being in later life. Psychometric data on several gerontological scales are presented in detail. Structural analyses of a variety of measures of subjective well-being are discussed and evidence for a one factor structural solution to subjective well-being is presented. Objective predictors of subjective well-being are discussed with respect to the strength of their relationships to subjective well-being. It is concluded that subjective well-being is the best predictor of itself. Evidence of temporal stability and corss-situational consistency, combined with the evidence of a one factor structural solution, suggests that subjective well-being has trait-like characteristics. Suggestions for future research are presented.  相似文献

Motor Vehicles in China: The Impact of Demographic and Economic Changes   总被引:2,自引:0,他引:2  
While China's transportation sector is relatively small compared to other nations—both in absolute terms and relative to the size of the population—the nation is currently experiencing one of the highest annual motorization growth rates in the world. This rapid growth has raised both excitement among business leaders over the potentially enormous market for automobiles and concern among environmentalists over their further impact on the global environment. This paper examines the influence of population growth, increased urbanization, and economic development on the rapid growth of motor vehicles in China, and considers their implications for future motor vehicle growth in the country.  相似文献

This paper examines changes in the mean levels of domain indicators of happiness, as well as happiness itself, using a longitudinal design. Results show that for a large sample of the elderly, mean levels of subjective domain indicators of happiness (excluding subjective health), as well as happiness itself, did not change over the 18-month period of the study. Physically related objective domain indicators, on the other hand, did change during the same time period.  相似文献

A thorough search was made of United States Federal Government publications in an effort to uncover government interest and action on homosexuality in the United States. No references were found prior to 1920 to government publications that refer to homosexuality. Since that time there has been sporadic interest in the subject, and from 1975 onwards it has been raised in Congress every year. There have been many hearings and reports that deal with the subject both directly and indirectly. Besides the bibliographic entries that follow, sources of information are listed and some annotation and discussion of the documents are included.  相似文献

This paper argues for the use of social indicators, in conjunction with the traditional norm-referenced and criterion-referenced tests, to assess the effects of local educational systems. A conceptual framework for the study of educational performance is presented, interrelating (1) personal resources invested by youth, (2) opportunities for development, (3) developmental behaviors, (4) educational system impacts, and (5) other contextual variables, which together affect (6) progress toward adulthood. Four types of variables and 15 content areas that should be monitored are described, with examples of social indicators for each. Procedures are presented for selecting variables, collecting time-series data, and analyzing and reporting the indicators, relying entirely on existing data sources. Appendices include a data base screening form, a statistic screening form, and a list of United States national, state, county, and city sources of time-series data relevant to youth development and educational performance.  相似文献

Abstract This paper discusses the relationship between the level of mortality at ages one to four, on one hand, and five to 34 on the other. This relationship has been observed to vary considerably among mortality schedules at different levels of mortality and even among schedules at the same general level of mortality. This variation is shown among the modem life table systems of the Regional Model Life Tables and the United Nations Model Life Tables. Controlling for the leyel ofmortality from age five to age 34, the West Tables and the United Nations Tables embody approximately the same 'average' relationship between early childhood and adult mortality. Relatively to this average relationship, the South and East Tables consistently display higher childhood mortality rates for a given level of adult mortality. Indeed, the childhood rates of the South Table are twice those of the West Tables over a range of life expectancy at birth from 40 to 70 years. The relationship between childhood and adult mortality from 1957 to 1968, a period of rapid mortality decline, was investigated in Taiwan. In 1957, the Taiwanese data reflected the severe childhood mortality of the South Model Tables. However, by 1968, due to an especially large decline in childhood mortality, this relationship was more moderate and resembled the mortality pattern of the West or East Model Tables. An analysis of the decline in cause-specific mortality during the period revealed that a dramatic decline in childhood mortality from gastro-enteritis was primarily responsible for the shift in the relationship between childhood and adult mortality in Taiwan. It is asserted that, while any of several diseases which result in fatalities primarily among children of pre-school ages, could cause relatively severe childhood mortality, gastro-enteritis is likely to be a primary contributor to such an age pattern. This assertion is based on the fact that, especially in the developing areas of the world, malnutrition and gastro-enteritis are usually precipitating and complicating factors of other childhood diseases. A limited test of this hypothesis was provided by considering the causal components of childhood mortality rates in two populations known, for certain periods, to have exhibited relatively severe childhood mortality conditions; Spain and Portugal. For the years in which those populations were characterized by the South mortality pattern, gastro-enteritis was a principal cause of mortality in childhood. Moreover, with the decline in mortality from gastro-enteritis, the mortality pattern in Spain and Portugal no longer exhibited childhood mortality rates which were severe relative to those of adult life. The implications of these findings for the analysis of mortality conditions in many areas of the developing world, where the gastro-enteritis malnutrition syndrome annually claims a heavy toll of life in early childhood, are not clear. In those areas, the effect of this syndrome on the age pattern of mortality could be offset by special conditions inflating adult mortality rates. Nevertheless, in circumstances where there is evidence indicating substantial childhood mortality from this syndrome and no evidence indicating compensating severe adult mortality, there is reason to suspect that the existing mortality pattern reflects the relatively severe childhood mortality conditions of the South Model Tables. Additionally, where mortality from the gastro-enteritis malnutrition syndrome has been severe in past years, but has been reduced to low levels in recent years, it is probable that the relationship between childhood and adult mortality will shift in favour of the former - quite possibly, in the manner of Taiwan, from a South to an East or West age pattern.  相似文献
