The paper investigates population change and migration over the period 1984–1994 for communes. There are important conclusions emerging from this study. The first is that we are watching now a profound change of population redistribution patterns in Poland. We observed that direct upwards hierarchical mobility has been markedly modified. The first modification is the substantial reduction of migration from rural to urban locations. There were important changes in the role of cities and towns. Largest cities, massive gainers of the seventies and eighties, have tended to lose population in the mid-nineties. It is likely that they lose population mainly to the neighbouring communes. We believe that a suburbanization process has been put into motion. Medium to large sized towns and cities, in the range between 50,000 and 500,000 as well as small, but not the smallest, towns attract substantial parts of the migration pool. 相似文献

This paper relates a review of the English language literature on quality costing and traces its historical development; it provides authoritative reading on the subject. The review also has a focus on collection and use of quality-costing methods, quantitative cost data and the role and views of accountants in the task of quality-cost collection and reporting. Amongst the main findings is the preoccupation with the prevention – appraisal – failure categorization of quality costs and lack of guidance on definitions. The considerable impact of the American quality profession on the development of quality costing is pointed out along with the increasingly positive stance of accountants. 相似文献

Segregation and Mortality: The Deadly Effects of Racism? 总被引:10,自引:0,他引:10
Elevated rates of mortality for African Americans compared to whites, coupled with the persistence of high levels of racial residential segregation, have directed attention to the structural manifestations of racism as potentially important pathogens for health. Using national mortality and census data for 1990 and a measure of black social isolation from whites, we examine the association between residential segregation and mortality in 107 major U.S. cities. Our analyses revealed that black social isolation tended to predict higher rates of mortality for African American males and females, although the strength of the association varied by cause of death. Socioeconomic deprivation explained a modest part of this association for black males but not for black females. Our analyses also found that a positive association between social isolation and mortality was more pronounced, for both blacks and whites, in cities that were also high on the index of dissimilarity. These findings highlight the need for research to identify the specific mechanisms and processes that link residential environments to adverse changes in health status. 相似文献

Recently there has been a great deal of interest in studying monetary policy under model uncertainty. We point out that different assumptions about the uncertainty may result in drastically different “robust” policy recommendations. Therefore, we develop new methods to analyze uncertainty about the parameters of a model, the lag specification, the serial correlation of shocks, and the effects of real‐time data in one coherent structure. We consider both parametric and nonparametric specifications of this structure and use them to estimate the uncertainty in a small model of the U.S. economy. We then use our estimates to compute robust Bayesian and minimax monetary policy rules, which are designed to perform well in the face of uncertainty. Our results suggest that the aggressiveness recently found in robust policy rules is likely to be caused by overemphasizing uncertainty about economic dynamics at low frequencies.

The investigation of alleged child abuse should be multi-professional and coordinated to minimize distress to the child and family. Much attention has focused on the joint interview process, with less prominence being given to the medical component of the initial investigation. No standard practice exists in the United Kingdom regarding the conduct of the medical examination or in the training requirements of the doctors who perform the examination. We present a model of practice which has evolved in Edinburgh and the Lothians, drawing on the combined expertise and experience of paediatricians and police surgeons, which has operated for over 2 years; and propose a formal accreditation process for doctors who wish to specialize in the field of child abuse. © 1998 John Wiley & Sons, Ltd. 相似文献

In the past 15 years, research activities focusing on the interlinkages between climate change and human mobility have intensified. At the same time, an increasing number of actors and processes have sought to address human mobility in the context of climate change from a policy perspective. Hitherto, research has been limited in terms of geographical preferences as well as conceptual and methodological focus areas. This paper argues that to address the evolving policy space, future research on climate change in the context of human mobility needs to become more differentiated, integrated and generalized. This includes concerted efforts to better integrate researchers from the global South, improved cross-linkages between different datasets, approaches and disciplines, more longitudinal and comparative studies and development of innovative qualitative and quantitative methods. 相似文献

AbstractTeaching about the comfort women of World War II offers a compelling case study for the social studies classroom and human rights education. The topic will educate students to become knowledgeable about the larger world and its dark histories that have been omitted or scarcely mentioned in U.S. history textbooks. This article provides high school social studies teachers with the historical background of comfort women, rationales for including this topic in social studies curriculum, and teaching strategies and resources that teachers can use in their classrooms. 相似文献

This evaluation assessed whether participation in Parents Anonymous mutual support groups was associated with child maltreatment prevention. Parents new to groups across the United States were interviewed at baseline, one month, and six months. Using standardized scales, all parents showed improvements in some child maltreatment outcomes, risk factors, and protective factors. Parents starting out with particularly serious needs showed statistically significant improvement on every scale. Results indicated that Parents Anonymous participation contributes to child maltreatment reduction. 相似文献
