The 1st millennium AD was a time of great transition in Europe and the Mediterranean. At the heart of the Byzantine Empire, Constantinople (modern day Istanbul) was a pivotal trade hub for the Aegean region. Establishing a precise and accurate dating framework for the development of this remarkable city and a chronological reference for this critical time period for the Mediterranean region is of great importance to a wide range of scholars. Here we present a new 213 year tree-ring record from 89 oak samples placed in time by dendrochronology and supported by radiocarbon analysis and historical documentation. It represents the middle of the first millennium AD in Constantinople. The tree-ring series are derived from pilings recovered from the extraordinary excavations of the so-called “Theodosian harbor” at Yenikap?, Istanbul, along with timbers from other sites and buildings around the city, including one of the most famous sites on the Istanbul sky-line—Hagia Sophia. They provide potential for new insight into a time period in which earthquakes, the Justinianic plague, and even a possible tsunami struck the city, and during which dramatic changes in climate have been recorded in other paleoenvironmental proxies. The chronology is the first published tree-ring series from the Aegean region to cover the ‘event’ years of AD 536–7 and 542 which are characterized by anomalous growth in other tree-ring series from around the world, but interestingly these event years are not evident in this tree-ring sequence. 相似文献

A pilot study of an opal phytolith morphotype series diagnostic for palms (Arecaceae), using modern specimens of four economically important palm species (Areca catechu L., Calamus aruensis Becc., Cocos nucifera L., and Metroxylon sagu Rottb.), was undertaken to identify distinctive features of leaf phytoliths from each taxon. Our univariate and multivariate analyses documented that although it was not possible to identify individual palm phytoliths unambiguously to taxon, interspecific differences in phytolith morphology significantly outweighed intraspecific variation, revealing the potential value of further research in this area and the possible utility of assemblage-level analysis to palm phytoliths in archæological assemblages. The methods are applied to archæological phytoliths from Watom Island, East New Britain, Papua New Guinea, and directions for further research outlined. 相似文献

Although there is a growing scholarship on the history of amateur meteorology, contemporary amateur meteorology has tended to remain a largely invisible social phenomenon. Moreover, questions of female involvement and gender relations therein have tended to be overlooked. This paper seeks to address this gap by drawing on interviews with members of one of the most important amateur meteorological networks in the UK—the Climatological Observers Link. The research identifies a predominantly male bias within amateur meteorology in the UK, offers insight into why and how this bias has emerged and explores the implications of this bias for gender politics in the home. It also considers the way in which, as a pursuit that is very much situated within the domestic sphere, amateur meteorology complicates traditional framings of the home as a female realm and contributes to a domestic masculinity. 相似文献

Abstract This article investigates Tom Wolfe's assessment of the age-old debate between nature and nurture, the Cartesian mind–body problem, and the tensions between science, politics, and morality that result from the human struggle to explain what the components of a human being are. I begin with Wolfe's own study of what evolution and neuroscience tell us about the “Human Beast.” Wolfe is not certain that evolution tells the whole story of how human beings came to be who and what they are in the twenty-first century. Evolution got us to the point of speech but Wolfe is persuaded that at that point, evolution ended and speech took over. Speech, according to Wolfe, made the development of reason and ingenuity and the creation of culture possible. And it is culture, the shared set of human behavior, knowledge, and beliefs, manners, and mores, and, above all for Wolfe, status, which then informs human motivation and actions. Wolfe is open to the idea that neuroscience might eventually be able to explain every detail of how and why the human brain functions as it does but he is skeptical that it will be able to explain away completely the idea that each of us is an individual, striving for honor and success within our status sphere. 相似文献

Local Government Portfolios and Regional Growth: Some Combined Dynamic CGE/Optimal Control Results 总被引:1,自引:0,他引:1
A theoretical policy model is presented that combines regional dynamic CGE modeling and optimal control to explore the role of local government taxation and expenditure in enhancing regional growth. It contributes to the regional CGE literature by explicitly solving for an optimal policy and augments earlier regional optimal control models by adding endogenous optimization of producer and consumer agents in response to endogenously determined prices. Results of three policy regimes are analyzed in terms of gains in the objective function, impacts on income inequality, and sensitivity to model parameterization. 相似文献
