This paper analyzes the long‐term transformations of the occupational structure in 50 provinces of Spain with a view to ascertain the existence and assess the extent of employment polarization. The peculiar characteristics of this country, namely rigid labor markets and the relatively recent transition to democracy, make for an interesting addition to existing studies on this topic. In line with previous literature on other countries, we find a strong association between the decline of “routine” mid‐skill jobs and the expansion of low‐skill service employment as well as differential labor market outcomes by levels of formal education. Results are robust to various controls and instrumental variables that account for long‐term industry specialization. We also find a positive local multiplier effect of high‐skilled workers on the demand for nontradable service jobs.  相似文献

This review discusses recent challenges to the welfare state arising from the Great Recession (GR). The GR was a significant event for social policy analysts, as it tested the responsiveness of welfare systems in the midst of a recent trend toward austerity politics in advanced economies. Social policy changes were part of the toolkit advanced democracies used to respond to the GR, and the welfare state mitigated the consequences of the GR. However, a stark limitation of the social safety net in the United States was the failure to assist immigrant households. The nexus of immigration and social policy is likely to be a significant controversy as we consider the meaning of social citizenship.  相似文献

Travertine was one of ancient Egypt's most popular ornamental stones. Upon prolonged exposure to sunlight, the rock's translucent brownish calcite is bleached to nearly white. Ultraviolet and gamma irradiation experiments were undertaken to investigate the source of the brownish colour and the process by which it fades. It was found that the coloration results from the activation of colour centres by natural radioactivity within the rock, and that these colour centres are deactivated by the ultraviolet component of sunlight. The results also demonstrate that the original brownish colour of sun‐bleached, travertine objects can be restored by artificial gamma irradiation.  相似文献

Imbued with profound historical consciousness, the Chinese people are Homo historiens in every sense of the term. To be human in China, to a very large extent, is to be historical, which means to live up to the paradigmatic past. Therefore, historical thinking in traditional China is moral thinking. The Chinese historico‐moral thinking centers around the notion of Dao, a notion that connotes both Heavenly principle and human norm. In view of its practical orientation, Chinese historical thinking is, on the one hand, concrete thinking and, on the other, analogical thinking. Thinking concretely and analogically, the Chinese people are able to communicate with the past and to extrapolate meanings from history. In this way, historical experience in China becomes a library in which modern readers may engage in creative dialogues with the past.  相似文献

Having been adopted by legislatures in over a dozen states, postsecondary merit aid programs are largely concentrated in the southeastern United States. The observed clustering pattern seems to support previous evidence that policies spread between proximate states, a phenomenon referred to by political scientists as policy diffusion. Often, however, policy diffusion is not complete, and one or more states in a region fail to adopt. By interviewing policymakers throughout the southeastern United States—including actors in the three states in the region without merit aid—the study addresses the following question: Why do diffusion pressures lead to adoption in some states but not in others? Studying state “hold‐outs” promises not only to uncover the reasons for failed legislation in specific state contexts but also to better our understanding of the limits of diffusion theory.  相似文献

Four blue-glazed faience jars, on exhibition in the Louvre Museum, are referred to as the canopic jars of Rameses II. Their recent typological re-examination rendered this original assignment questionable. In order to clearly determine their use, a study of two successive organic residues from the canopic jars, using molecular biomarkers analysed by GC-MS and LC-MS and absolute dating by 14C, was initiated. The results revealed that these two materials were not contemporary to the reign of Rameses II. The first one, scraped from the interior face of one jar, was identified as an unguent made of coniferous oil and animal fat and dated from the Third Intermediate Period. The second one, originally stored with glued linen inside one jar, is likely an embalming substance, made of pure vegetable resin (Pistacia) and dated from the Ptolemaic Period. These results clarify a controversy which has been lasting over a century. The famous blue-glazed faience jars are not the canopic jars of Rameses II but are confirmed as situlae which were reused at least two times: first to store unguents during the Intermediate Period and later to store embalming packages of an unknown person during the Ptolemaic period.  相似文献
