Summary: Mummified human remains have been preserved in the cool, well-ventilated crypts of old Finnish churches, which were popular burial sites among the elite of the early modern period. Here, the authors present the results of a computed tomography study of the remains of an early 17th-century vicar of Keminmaa. They examined the preservation of his remains and made several pathological findings; the causes of the latter possibly had a severe impact on his health. He was a large man who achieved relative longevity for his time, although he suffered from conditions related to obesity. There were also potential indications of tuberculosis. Inflammatory changes, for example, had afflicted his spine. 相似文献

This article demonstrates the relevance of future discounting behavior to studies of prehistoric subsistence strategies. The case study of Agave spp. bajada cultivation among the Classic Period, a.d. 1150–1450, Hohokam of southern Arizona illustrates how slight discounting of future rewards can significantly alter agriculture investment strategies. Despite a higher kcal/hour return than maize agriculture, agave cultivation lessened or ceased in several communities during a time in which intensification would be predicted due to inferred subsistence stress. We surmise the decade-long maturation of agave made it unattractive relative to more immediate return resources in any context that presented risks to land tenure. The cessation of agave cultivation can be understood on two levels of explanation. The long-term investments required by agave and tendency to discount future rewards are the ultimate causes. Political and social instability during the tumultuous Classic period, causing increased insecurity in land tenure, are the proximal causes. 相似文献

Over one hundred years of palaeontological research in northwestern Argentina has provided extensive knowledge of Andean lower Palaeozoic fossil assemblages, with trilobites, graptolites, brachiopods and echinoderms being among the most prominent groups. This record is enriched by the recent discovery of soft-bodied worms in Cambrian outcrops of northwestern Argentina. Palaeoscolex sp. cf. P. ratcliffei from the Furongian Lampazar Formation in Jujuy is described, considerably expanding the biogeographical range of this genus and filling the distributional gap, between the well-known early–middle Cambrian occurrences of Palaeoscolex and those of its Ordovician species. 相似文献

Carlorosi, J., Heredia, S. & Aceñolaza, G, 2013. Middle Ordovician (early Dapingian) conodonts in the Central Andean Basin of NW Argentina. Alcheringa 37, 1–13. ISSN 0311-5518. This paper describes and analyzes the significance of a conodont fauna from the Alto del Cóndor Formation, exposed in the Los Colorados region of the Argentine Eastern Cordillera. Identified taxa are Baltoniodus triangularis, Baltoniodus sp. cf. B. triangularis, Drepanodus sp., Drepanoistodus basiovalis, Drepanoistodus sp. B., Erraticodon patu, Gothodus costulatus, Oistodus sp., Trapezognathus diprion, T. quadrangulum, Triangulodus sp. and Triangulodus? sp. The presence of Baltoniodus triangularis indicates the base of the Dapingian stage (Middle Ordovician). In addition, we report the coexistence of T. diprion and T. quadrangulum. The conodont association suggests a faunal affinity with Baltica and South China, both belonging to the Shallow-Sea Realm of the Temperate-Cold Domain.

Abstract Through a critical consideration of recent proposals urging the use of “citizen forums” or “mini-publics” on issues involving science, this article reflects on the challenge posed to democracy and democratic decision making by the intellectual authority of modern science. Though the danger of a descent into technocracy is real and pressing, arguably the most serious challenge to democracy today, these novel “deliberative democratic” institutions are unpromising as a corrective beyond the local level, and may actually exacerbate the problem. The article concludes with a consideration of alternatives. 相似文献

ABSTRACTHoteliers have steadily been able to reduce costs and increase employees’ workload as a result of mass unemployment sparked by the financial crisis, beginning in 2008, and associated legislative reforms by the Spanish government. Outsourcing has been hotels’ main instrument in this drive. Hotel chambermaids are among the groups most affected by this phenomenon. This article analyses the impacts of outsourcing on hotel maids’ working conditions, while questioning the possibilities for achieving inclusive tourism given the current outsourcing trend. It is based on 44 in-depth interviews with a range of informants, including 24 hotel maids who have experienced the process of outsourcing, in major Spanish tourism destinations. This study aims to understand the changes these workers have experienced and perceived in their working conditions. The research results highlight a marked deterioration in hotel maids’ working conditions in recent years, most notably involving (a) a reduction in their salary and the loss of professional categories, (b) work overload, (c) greater uncertainty in the duration of employment, timetables and work schedule, (d) de-professionalisation, (e) segmentation, division and an increase in competition between hotel staff, (f) the accentuation of health problems and (g) a decrease in the capacity of representation and the defence of workers’ collective interests. 相似文献

Seismic performance of historical vaulted adobe constructions: a numerical case study from Yazd,Iran
Neda H. Sadeghi Daniel V. Oliveira Mariana Correia Hamed Azizi-Bondarabadi Agustín Orduña 《International Journal of Architectural Heritage》2018,12(5):879-897
Past earthquakes have demonstrated that historical vaulted adobe buildings are highly vulnerable to seismic actions. Hence, it is crucial for such building typologies to be evaluated in terms of seismic capacity. To this end, this article deals with the seismic performance of historical vaulted adobe houses from the city of Yazd, Iran as one of the seismically active areas of the world and possessing a very rich adobe heritage. Thus, and based on a detailed geometrical survey, a representative sample of adobe houses from Yazd was studied using a simplified in-plane analysis based on three geometric indexes. Concerning the out-of-plane behavior, a deeper assessment was conducted by performing a numerical study, where the main influential parameters on the seismic behavior of vaulted adobe buildings were considered. The numerical analyses were carried out by adopting the limit analysis theory implemented in the Block2D software. The results obtained indicate the safe in-plane behavior of most of the houses and the safe out-of-plane response of the sample under gravitational loads. However, the sample out-of-plane safety under earthquake-induced loads seems to be a matter of concern. 相似文献
