Quaternary stratigraphy and sea level changes have been extensively investigated in many areas of the Mediterranean. However, numerical dating of coastal deposits and the associated paleoenvironmental information are limited for the coasts of Cyprus, principally based on radiometric and radiation-exposure geochronological techniques on fossils which bear a range of limitations and uncertainties. As such, optically stimulated luminescence (OSL) dating techniques are deemed to be the most suitable in direct dating of the coastal sediments of Cyprus. In the southeastern Cyprus, coastal dunes (aeolianites) now forming elongated ridges appear as morphological features running parallel to the current shoreline presenting an indicator of sea level and climate changes of great paleoenvironmental significance. We present our first chronological results for the exposed aeolianites and underlying littoral deposits formed along the southeastern coastal Cyprus ranging from 78.4 ± 9.9 to 56.2 ± 7.4 ka. The post-infrared–infrared stimulated luminescence (pIR-IRSL) revealed that dune formation took place during the marine isotope stages (MISs) 3, 4, and possibly 5a. Late Holocene reworking is proposed for a distinctively isolated dune with an age of ~1.3 ka ago. This study also showed that pIR-IRSL dating of feldspars may be a reliable alternative to quartz OSL dating when the quartz luminescence characteristics are unsuitable.  相似文献

Breathtaking parades of black kings and their courts enlivened the streets of cities in Europe and the Americas between the fifteenth and the eighteenth centuries. Sumptuously dressed queens and kings and their resplendent attendants processed to the sound of music, lifted, temporarily, from the grim the life of enslavement or institutionalized inferiority many of them lived in the age of Atlantic slavery. Drawing from a recent analysis of a prominent ritual performance from the central African kingdom of Kongo called sangamento, this article offers a new interpretation of the black kings festivals, beyond their interpretation as carnivalesque pomp emulating and destabilizing European rule. On both shores of the Atlantic, the performances combined African and European regalia and pageantry to express and enact central African collective identity, political power, and social unity. Restaging performances and reshaping ideas honed in the Kongo, enslaved central Africans not only preserved the memory of their region of origins, but also crafted empowered responses to enslavement and the colonial system at large.  相似文献

A recently found cattle-based mandibular thong-smoother, which was the only bone tool in the Baden culture burial of a 6–10-year-old child at the site of Balatonlelle-Rádpuszta-Romtemplom mellett (western Hungary), represents the best-preserved Eneolithic implement in this category ever published in Hungary. Being one of the oldest specimens from the distribution area of mandibular thong-smoothers, it brings new information regarding the origin and possible use of this rarely identified type of tool linked to strap and thong-making in the period from the Eneolithic to the Middle Bronze Age. Having been recovered from the grave of a child, it draws attention to the possibility that children may have been involved in strap production. The evaluation of analogies from and outside of Hungary also offered a complex review of mandibular thong-smoothers. In addition to the role of these implements in taming and driving horses already discussed in the specialist literature, we also point to their involvement in the use of harnessed cattle for draught and transport, and its linkage to the spread of wagon and carriage in the wake of the 4th millennium.  相似文献

Abstract

This paper examines the development of the field of feminist geographies in Brazil, proposing a reflection upon the different aspects of the policy (personal, institutional and national/international) which are intertwined with the geographical scientific production on gender and sexualities. This research is based on a data survey comprising 17,636 papers published between 1974 and 2015 in 90 scientific journals kept by Brazilian geographical entities at all levels of the ranking established by the government. The study emphasizes that there was an expansion of the gender and sexualities approach after the 2000s, characterized for its production from the peripheral universities, by young researchers and its publication in scientific journals of lower scientific impact, when the formal criteria of evaluation recently set in Brazil are taken into consideration. The gender studies field can be considered consolidated in Brazil, however, the approach of sexualities in the Brazilian geography still requires some work to be finally recognized.  相似文献

This paper describes environmental systems games developed for energy and water resource use designed to be adaptable from high school to undergraduate use. Two of the games are computer simulations with adjustable levels of difficulty that can be done in a computer lab or as a homework assignment. The third is a peer-to-peer roleplayer game designed for an immersive in-class simulation. For the energy and the peer-to-peer water games, we describe (1) the overall strategy or story line adopted, (2) the manner in which the game is played by students in a classroom setting, (3) the use of scientific literature in conceptualizing and parameterizing the game, and (4) possible game extensions. Preliminary data from use at the undergraduate level shows that the games are very well-received by students and, consistent with other research on quasi-experimental simulations, likely enhance learning outcomes.  相似文献
