Peter Ashby 《Social Policy & Administration》1985,19(3):191-198
In July 1985 the National Council for Voluntary Organisations launched a campaign for "action for the forgotten million"— the four out of every five long-term unemployed people who receive no practical support from the public services, apart from their benefits. The author of the National Council discussion document outlines some of the major issues which will need to be faced. In particular, he argues that public debate tends to concentrate too narrowly on specific initiatives and individual programmes. Instead, there is a need to consider the rights of all long-term unemployed people, and the needs of the group as a whole. 相似文献

在新巴塞尔资本协议(New Basel Capital Accord)对金融全球化的冲击及金融机构改善资产质量及合并政策的影响下,我国台湾地区金融业进入激烈合并竞争的时代.许多银行颇受降低逾放比率及增加净值报酬率与资产报酬率两难之困扰.消费性信用贷款产品利差大、风险分散,是金融机构授信经营极重要的产品.实证结果显示,采用世代研究(cohort study)建立之模型对样本数据之拟合程度较个案对照研究法(case-control study)的解释变异量为佳,且较符合新巴塞尔资本协议规定及科学程序.虽然Logistic 回归模型在建立逾期概率模型上广泛地被使用,但要求存在于同构型的变异数Var=np(1-p)假设上,且在数据分析上常因为出现变异数之异质性问题,故可采用调整变异数异质性之方法. 相似文献

Two habituation experiments were conducted to investigate how 4‐month‐old infants perceive partly occluded shapes. In the first experiment, we presented a simple, partly occluded shape to the infants until habituation was reached. Then we showed either a probable completion (one that would be predicted on the basis of both local and global cues) or an improbable completion. Longer looking times were found for the improbably completed shape (compared to probable and control conditions), suggesting that the probable shape was perceived during partial occlusion. In the second experiment, infants were habituated to more ambiguous partly occluded shapes, where local and global cues would result in different completions. For adults, the percept of these shapes is usually dominated by global influences. However, after habituation the infants looked longer at the globally completed shapes. These results suggest that by the age of 4 months, infants are able to infer the perceptual completion of partly occluded shapes, but for more ambiguous shapes, this completion seems to be dominated by local influences. 相似文献

There is an emerging consensus in empirical finance that realized volatility series typically display long range dependence with a memory parameter (d) around 0.4 (Andersen et al., 2001; Martens et al., 2004). The present article provides some illustrative analysis of how long memory may arise from the accumulative process underlying realized volatility. The article also uses results in Lieberman and Phillips (2004, 2005) to refine statistical inference about d by higher order theory. Standard asymptotic theory has an O(n-1/2) error rate for error rejection probabilities, and the theory used here refines the approximation to an error rate of o(n-1/2). The new formula is independent of unknown parameters, is simple to calculate and user-friendly. The method is applied to test whether the reported long memory parameter estimates of Andersen et al. (2001) and Martens et al. (2004) differ significantly from the lower boundary (d = 0.5) of nonstationary long memory, and generally confirms earlier findings. 相似文献

Summary. We develop a general methodology for tilting time series data. Attention is focused on a large class of regression problems, where errors are expressed through autoregressive processes. The class has a range of important applications and in the context of our work may be used to illustrate the application of tilting methods to interval estimation in regression, robust statistical inference and estimation subject to constraints. The method can be viewed as 'empirical likelihood with nuisance parameters'. 相似文献

Expectations, Capital Gains, and Income 总被引:2,自引:0,他引:2
A theoretical framework for the measurement of income under uncertainty is developed that addresses some long-standing controversies about the treatment of capital gains. The consequences for economic analysis and policy making are potentially serious, because the treatment of capital gains can significantly affect some major macroeconomic aggregates, including national income and savings, balance of payments deficits, government deficits, and depreciation.

Peter M. Hall 《Symbolic Interaction》2003,26(1):33-55
With its roots in American pragmatism, symbolic interactionism has created a distinctive perspective and produced numerous important contributions and now offers significant prospects for the future. In this article, I review my intellectual journey with this perspective over forty years. This journey was initiated within the American society, sociology, and symbolic interaction of circa 1960. I note many of the contributions made by interactionists since that time, with particular focus on those who have contributed to the study of social organization and social process. I offer an agenda for the future based on currently underdeveloped areas that have potential. These are inequality orders, institutional analysis, collective action across space and time, and the integration of temporal and spatial orders. The article concludes with calls for further efforts at cross‐perspective dialogues, more attention to feminist scholars, and an elaborated critical pragmatism. 相似文献

The discovery of participatory research as a new scientific paradigm: Personal and intellectual accounts 总被引:1,自引:1,他引:0
Peter Park 《The American Sociologist》1992,23(4):29-42
The article presents considerations for the placing of participatory research in the practice of sociology. The changing conditions
in contemporary society have compelled social scientists to rethink the way social theory has been conceptualized and has
been practiced in relation to social change. Modernist social theory, of which sociology is a prime example, has been imbued
with the biases of the Enlightenment that privilege the essentialized male rational actor set above the ordinary people. As
a consequence it has produced narratives and practices that are not in the interest of the people, especially those who have
been dominated and oppressed. In order to live up to the potential of sociology as a vehicle for the improvement of social
conditions, it must include the interest and the wisdom of the people in its researching and theorizing activities. It is
argued that participatory research provides an opportunity to follow this course in sociology. Participatory research, it
is contended, will lead to a paradigm shift in the social sciences because it is based on an expanded conception of knowledge
and because it changes the relationship between the researcher and the researched and between theory and practice. Arguments
are drawn from the history of science, critical theory, and postmodernist and feminist critiques.

Abstract This paper examines rural/urban differences and trends in mental health during the farm crisis of the 1980s in a large panel sample from a midwestern state. A community research perspective, which attributes differences to life styles, culture, and community context, is contrasted with an economic stress perspective, which focuses on individual differences in economic circumstances as determinants of rural-urban differences in mental health. Survey samples from 1981, 1986, and 1989 are used to examine differences among seven categories of community type. Multiple regression analysis of the trend and panel data provide support for both the individual economic distress and community context models. 相似文献

Federal minimum wage statutes cover only 70 percent of the work force and 30 percent of all employers. State laws are designed
to close some of these coverage gaps and in some cases to set higher wage floors. Hence, differences in state wage floors
and coverage should affect employment rates and wage distributions, particularly among low-skilled workers. Evidence from
the National Longitudinal Ssurveys of Youth is mixed, however: State wage floors appear to have no impact on youth employment
or entry wages, but coverage exemptions appear to increase both employment and wages. These observations underscore the need
to include state provisions in models of minimum wage impacts, particularly for later periods (e.g., 1988–1991) when state
wage floors were relatively higher. 相似文献
