In the constellation of the eighteenth-century revolutions, the French events have always occupied a dominant position. Consequently the other European upheavals have been considered as being provoked or strongly influenced by France. Yet, the Dutch revolutions in the 1780s and 1790s provide some important nuances to this interpretation. Before the French took over the Bastille, there was already a Dutch revolution with devoted Patriots, speaking about rights of man and constitutions. The Patriots had to flee abroad in 1787. In 1795, thanks to the French Army, they were able to return to their drawing boards, eager to think anew their government and society. This paper investigates how they did it and whether the American and French precedents were so influential after all in the construction of the Batavian Republic.  相似文献

Marsola, J.C.A., Grellet-Tinner, G., Montefeltro, F.C., Sayão, J.M., Hsiou, A.S. & Langer, M.C., 2014. The first fossil avian egg from Brazil. Alcheringa 38, 563–567. ISSN 0311-5518.

In contrast to the rich record of eggs from non-avian dinosaurs, complete eggs attributable to Mesozoic birds are relatively scarce. Nevertheless, several well-preserved specimens have been discovered over the last three decades revealing functional and phylogenetic characters that shed light on the breeding strategies of extinct birds. Here we report the first fossil avian egg from Brazil, which was discovered in Upper Cretaceous strata of São Paulo in the southeastern part of the country. The taxonomic identity and structural features of the biomineralized tissues were determined using a combination of Scanning Electron Microscopy, Wave Dispersion Energy analyses and Computed Tomography. These show that the 125.5-μm-thick shell of the 31.4?×?19.5?mm egg incorporates three structural layers of similar thickness with both prismatic and aprismatic boundaries. Close similarity between the Brazilian bird egg and those of enantiornithines from the Upper Cretaceous Bajo de la Carpa Formation (Río Colorado Subgroup) of Argentina advocates affinity with basal Ornithothoraces. Furthermore, coherency of their depositional contexts might imply a compatible preference for breeding and nesting environments.

There is a rich, but unacknowledged, heritage of rural subalterns, crofters, in Scandinavia. A Swedish-Norwegian interdisciplinary research-network investigated the most prominent category – the remains of crofts. Due to industrialisation, urbanisation and the modern welfare state, the institution of crofting was abolished, and many crofters left for opportunities elsewhere. The welfare state transformed a landscape of living and working people into a one filled with relicts mostly from the nineteenth century. Although numerous and important to local citizens, these sites fall outside the authorised heritage discourse (AHD) in terms of both research and heritage management. This paper takes an environmental justice perspective to challenge the AHD. Three themes are in focus: (1) bringing out the history of a subaltern and marginalised group of people; (2) promoting crofts as heritage of importance to local citizens and demanding complex management due to the various historical narratives and risks; (3) considering the crofting landscapes in relation to the (economisation) framing of heritage in development processes, especially in relation to fair development in present rural communities.  相似文献

Augmented reality (AR) technology is commonly used in education. AR offers a combination of the virtual and real world; thus, it can help students in learning abstract and complex subjects. The purpose of the current study was to determine the impact of mobile AR technology on achievement, cognitive load levels and views of 95 first-year university students (40 in the experimental group and 55 in the control group) enrolled in a geography course in the social sciences education department of the education faculty of a university in Turkey. A sequential explanatory design, a mixed method type of research, was used. The data were collected using an achievement test, a cognitive load scale, and a semi-structured interview form. The results of the study showed that AR increases students’ achievement and decreases their cognitive load levels, and the students’ views about AR technology were positive. Consequently, it can be stated that mobile AR technology is a useful tool for teaching geography, especially geomorphology topics.  相似文献

This article provides a summary of the various maritime archaeology projects undertaken in the French Antilles (Guadeloupe and Martinique) since the 1980s that date to the 17th–19th century Colonial period. These projects are presented in the context of the principal maritime archaeological research questions. The results are analysed thematically touching on different aspects of archaeological research in littoral and underwater zones: coastal plantations, ports, and micro‐islets. Research carried out on wreck‐sites is presented with respect to their maritime use (commercial, naval, and cabotage). The nature and distribution of such sites provides information both on maritime routes and traffic, trade, conflicts, and environmental risks specific to the Antilles in the Colonial period.  相似文献
