We provide evidence, by combining Occupational Information Network (O*NET) data with monthly Current Population Survey data from 1990 to 2015, that occupations characterized by high cognitive and people skill requirements are less sensitive to recessions, conditional on educational attainment, industry, and individual characteristics. These results are driven by urban areas, particularly noncollege educated people in urban areas, and vary with city size. Finally, we provide the first evidence that metropolitan areas’ recovery from economic downturns depends upon initial skill composition of occupations in the area.  相似文献

Although the female labor force participation rate of women has been steadily rising in the United States, there is substantial variation across cities. Previous cross‐county studies find that gender inequality in employment reduces economic efficiency hindering growth. This result is examined in a regional context, across metropolitan areas in the United States. Throughout multiple model formulations including instrumental variables approaches, higher initial female labor force participation rates are positively related to subsequent wage growth in metropolitan areas between 1980 and 2010. Specifically, every 10 percent increase in female labor force participation rates is associated with an increase in real wages of nearly 5 percent.  相似文献

In the past few years, foreign policy tensions between China and Australia have become especially fraught. In some cases, this political situation manifests in the very diplomatic initiatives that were funded to help ease relations. This article considers a case study of a theatrical collaboration in the context of contemporary Australia–China relations to interrogate the value of our understandings of and evaluation frameworks for public diplomacy. This article argues that theories of cultural diplomacy and assessments of initiatives need to consider the multiple and competing objectives, diverse publics and controversial receptions that may be the outcomes of cultural diplomatic initiatives. It demonstrates this complexity in relation to Australia–China relations. Taking a cultural diplomatic initiative that sought to increase positive association for Chinese culture in the Australian public as a case study, it illustrates the range of differences that can be found amongst stakeholders, and the different roles that may be ascribed to cultural diplomacy. These interests, including those of different artistic and political stakeholders, as well as differences in the publics involved, are best segmented not only according to nation but also to subculture.  相似文献

Bergmann's and Allen's Rules predict a relationship between climate and morphology as a thermoregulatory adaptation. These ecogeographic principles predict/explain change in the ratio of body surface area to body mass in hot and cold climates. With regard to Allen's Rule we would expect short and relatively broad limb proportions. Such adaptation should be observable in skeletal architecture. This paper provides a test of Allen's Rule using osteometric data for the second metacarpal from the Sadlermiut of Southampton Island, Northwest Territories, Canada. Following adjustment for body size, ANOVA by sample and sex shows the Sadlermiut second metacarpal to be shorter, wider at the base and deeper at the distal metacarpophalangeal joint, in comparison to an historic sample of European settlers. This pattern of difference suggests an Inuit hand with a thermally adapted morphology, viz. a large mass relative to surface area. Copyright © 1999 John Wiley & Sons, Ltd.  相似文献

Pairing Thus Spoke Zarathustra with On the Genealogy of Morality foregrounds tensions between artistic creation and critical interpretation in Nietzsche's work. From The Birth of Tragedy to his genesis of the concept, Will to Power, Nietzsche describes the real, or “what is,” in terms of a creative, form-giving force. We might therefore read Zarathustra—a linguistically experimental, richly allegorical, self-reflexive, modernist prose poem—as the pre-eminent, artistic mode of philosophical expression, at least for Nietzsche. But Zarathustra is followed by a sober Abhandlung (treatise), which professes a scientific goal of “getting to the bottom of things” by uncovering the contingency, origin, and fabricated nature of supposedly eternal, “given” values. These instantiations of Nietzsche-the-artist and Nietzsche-the-critic suggest art's “double” or contradictory nature—a nature that accents its kinship with philosophy. Zarathustra and the Genealogy, read together, hint that the destruction of idols—or de-constructive, critical interpretation more generally—is not just supplemental to, but a necessary moment within the aesthetic itself.  相似文献

US inequality has rapidly increased since the early 1970s. For advanced economies, inequality is linked to stronger incentives that enhance growth, education, innovation and entrepreneurship. However, the rise in US inequality is concentrated in the top 1%. Hence it is increasingly possible that economic rewards may be too uncertain to promote effort, suggesting the US has crossed a tipping point in which inequality reduces growth. Other costs include more social and political instability, making inequality the next potential “crisis” facing America. This study first examines trends in inequality and then reviews arguments that suggest that it is both good and bad for growth in America's cities. We then provide evidence that there has been a reversal in the effects of inequality after 2000 with it now being associated with less income and job growth in US metropolitan areas. We conclude by arguing that no general solution is possible without significant political reforms that equalize political influence.  相似文献

One of the three main plant microfossils, starch grains are increasingly used as markers of diet, plant domestication, tool use and site organization, because their morphology and features provide a means to identify the plant that produced them. However, starch grains are susceptible to damage when they are exposed to heat in the presence of water, as in cooking. We documented the changes that occur in the starch grains of 10 domesticated plant species due to exposure to different cooking methods, in order to better understand how cooking alters the appearance of the grains, and if these cooking methods might be identifiable in the archaeological record. Our results show that some cooking methods produce unique, identifiable damage on some types of plant starches, but generally each plant species reacts uniquely to cooking. In order to record the changes for each plant species, we have created a database, available at (http://www.osresearch.net/∼hollyf/starchdb/index.cgi), to which registered users can add their own images of cooked starch grains.  相似文献
