We examine the factors leading to creation and growth ofnational Old-Age Insurance (OAI) and Health Insurance schemes.None of the theories we test fit the data very well. There isweak evidence that the probability of adopting a systemdeclines in a country's wealth and in the ethnic heterogeneityof its population. Catholic countries are more likely tocreate earnings-related OAI systems. The growth of OAIspending since 1960 has varied considerably across countries,with fast growth in countries emerging from dictatorship andnon-English speaking countries. We conclude that socialinsurance can be politically expedient for many differentreasons.  相似文献

This article focuses on developments towards an EU educational policy. Education was not included as one of the Community competencies in the Treaty of Rome. The first half of the article analyses the way that the European Court of Justice and the Commission of the European Communities between them managed to develop a series of substantial Community programmes out of Article 128 on vocational training. The second half of the article discusses educational developments in the community following the Treaty on European Union and the Treaty of Amsterdam. Whilst the legal competence of the community now includes education, the author's argument is that the inclusion of an educational competence will not result in further developments to mirror those in the years before the Treaty on European Union. If the 1980s were a decade of expansion, the medium‐term future is likely to be one of consolidation.  相似文献

This paper analyzes the relationships of schooling, the skill content of work experience, and different types of employment patterns with less‐skilled women's job quality outcomes. Survey data from employers and longitudinal data from former and current welfare recipients are used for the period 1997 to early 2002. The analysis of job quality is broadened beyond employment rates and wages measured at a point in time by including non‐wage attributes of compensation and aspects of jobs that affect future earnings potential. This study shows the extent to which lack of employment stability, job skills, and occupation‐specific experience impedes welfare recipients' abilities to obtain a “good job” or to transition into one from a “bad job.” The business cycle downturn has significantly negatively affected the job quality and job transition patterns of former and current recipients. © 2003 by the Association for Public Policy Analysis and Management.  相似文献

Automated scanning electron microscopy coupled with image analysis and X-ray micro analysis was used to characterize a variety of gunshot residue (GSR) samples. More than 500 rounds of commercially available ammunition and six different types of hand gulls were used in the study of 17 GSR and 19 reference specimens. The individual particle X-ray composition was determined for 12 different elements. Elemental composition of GSR particles was highly variable but consistent with compounds mixed into or associated with a barium oxide matrix. When present in a specimen, GSR could be adequately characterized with automated procedures in less than an hour by restricting analyses to features larger than 2 microm. In "clean" samples, a higher resolution particle search was required to avoid reporting false negatives. Careful control of the back scattered electron signal strength threshold, by reference to a standard, was needed to ensure both time-efficient and accurate analyses. Samples collected from non-shooting subjects. active in a physical environment which contained firearms discharge residue were seen to be easily contaminated by sub-micron GSR particles.  相似文献

A prospective longitudinal study was conducted to investigate whether anxiety, depressive, personality, or substance use disorders increase risk for onset of bulimia nervosa (BN) or binge eating disorder (BED) during adolescence. Axis I and II psychiatric disorders were assessed in a primary care sample of 201 adolescents. Axis I disorders were reassessed 10 months later. Youths with dysthymic disorder were at elevated risk for the onset or recurrence of BN or BED after preexisting psychiatric disorders were controlled statistically. Problems with depression or anxiety tended to precede the onset of eating problems. In addition, youths with eating disorder symptoms were at elevated risk for the onset or recurrence of depressive disorders. These findings suggest that adolescents with chronic depressive symptoms may be at elevated risk for the development of BN or BED, and that adolescents with eating disorder symptoms may be at elevated risk for the development of depressive disorders.  相似文献

AT the National Energy Work Conference in January 2011,the Chinese government doubled its 2020 target for installed nuclear energy capacity which was set four years ago,to 86 million kW.The country’s current energy shortage partly drives the decision as does its ongoing commitment to the international community for energy conservation and emission reduction.According to up-to-date statistics from the Nuclear Energy Institute of the U.S.that were made available at the conference,the number of nuclear power plants under construction in China accounts for more than 40 percent of the global total,ranking China first in the world for number of plants under construction.  相似文献
