We analyze whether efficiency wages operate in urban labor markets, within the framework proposed by Ross and Zenou, in which shirking at work and leisure are assumed to be substitutes. We use unique data from the American Time Use Survey (ATUS) that allow us to analyze the relationships between leisure, shirking, commuting, employment, and earnings. We confirm that shirking and leisure are substitutes, and present an estimate of this relationship, representing the only empirical test of the relationship between a worker's time endowment and shirking at work. Our findings point to the existence of efficiency wages in labor markets. 相似文献

The Middle Uruk phase in Mesopotamia (3600–3500 bc) has been characterised by the massive production of “bevelled rim bowls” (BRBs). They are characterised by their similar shape and volume in Mesopotamia and surroundings. However, their production method has not been studied in detail, including the firing temperature. The determination of the firing temperature of ancient pottery has been attempted by studying mineral phase transformation sequences; although, very little knowledge exists about such transformations in mixtures or thermal analyses. These methods usually provide imprecise firing temperatures between 500 and 800 °C, as other factors such as the raw materials or firing time and conditions must be considered. As an alternative, luminescence techniques have been tested with promising results, as they have provided reliable maximum firing temperatures for ancient pottery at mild conditions (below 600 °C) with high precision. In this work, the firing temperatures of BRB samples from two archaeological sites located in the Middle Euphrates Valley (Syria) have been studied using mineralogical, chemical and thermal analysis. Both mineral characterization techniques and thermal analyses show agreement and firing probably below 600–700 °C. Luminescence yields ambiguous results but circumstantial evidence on the firing temperature between 400 and 550 °C. 相似文献

This article analyses the role of the Instituto do Patrimônio Histórico e Artístico Nacional—IPHAN (the Brazilian Government’s Bureau for Cultural Patrimony Preservation) as an educational institution, considering the relationship between archaeology and education. Consideration of education both as a social practice and as a profession provides a basis for discussing the educational approaches of archaeologists. The authors stress the fact that IPHAN barely takes advantage of the important teaching tool that the archaeological knowledge produced in Brazil can provide for education about Brazilian cultural patrimony. 相似文献

This article examines how basic socioeconomic and political factors are associated with higher levels of cooperation to garner a local community's shared green reputation. We analyze panel data on participation efforts in a collective voluntary environmental program, the Ecological Blue Flag Program, by the entire population of beach communities in Costa Rica between 2001 and 2009. Collective voluntary environmental programs are relatively new and aim to improve environmental performance and shared “green” reputation through joint participation and certification of multisector groups comprising businesses, governmental institutions, and nongovernmental organizations. Our results indicate that higher levels of within‐community cooperation for shared green reputation are more likely in seashore localities with lower income inequality and/or a higher number of businesses. These findings run counter to research suggesting these same characteristics are associated with lower levels of cooperation in the management of common pool natural resources such as fisheries and forests. We also find that within‐community cooperation is positively correlated with a greater proportion of expatriates from industrialized countries and/or with higher levels of democratic political participation. 相似文献

ABSTRACTIn this article, after analyzing the comics industry in Spain in the context of the 2008 crisis, which reveals how small and medium publishers have adapted to new trends in consumption, I focus on the graphic novel Barcelona. Los vagabundos de la chatarra (2015) by Jorge Carrión and Sagar. This comic depicts the underworld of scrap metal collection in Barcelona, where mainly immigrant workers wander the streets, barely eking a living out of the detritus of consumerist society. It is an example of graphic journalism in comics, one of the most interesting developments in the genre in the past few years. It is also a novelty in Spanish comics because certain topics were far from common in the existing repertoire, which had been dominated by adventures, fantasy, and science fiction. Drawing on Verónica Gago's La razón neoliberal (2014) and Saskia Sassen's Expulsions (2015), I challenge conventional approaches to neoliberalism by focusing on neoliberalism from below, which is seen by Gago to point toward the emergence of a new historical consciousness of living in perpetual crisis. 相似文献

The study of fabrics, that is, the analysis of the orientation and slope of archaeological and sedimentary materials associated with the Middle Palaeolithic/Upper Palaeolithic (MP/UP) transition at Cova Gran shows substantial differences. Archaeological assemblages are characterised by greater isotropy in the fabrics than the sedimentary levels within which they are located, indicating that these differences may be generated by anthropic processes. One of the anthropogenic processes associated with horizontal and vertical displacement of archaeological artefacts is trampling and circulation caused by later occupations. In order to evaluate the effect of movement on materials, we undertook experiments simulating geological and archaeological conditions at Cova Gran. The results show that human trampling does not cause major isotropy in fabrics, but arranges archaeological assemblages towards planar or linear materials according to surface geometry. We were not able to replicate the fabric pattern of materials from the archaeological levels of Cova Gran, suggesting that they must be associated with the activities of human occupation at each level. 相似文献
