The eighteenth century was the heyday of Chinese traditional economic development, that the monetization and sharp increase in the supply of silver stimulated long-distance trade and the rise of regional merchants groups, and increased industrial and agricultural production all reflecting the overall economic development of this period. Along with commoditization and monetization of the economy, monetary supplies and government financial behavior had increasing influence on the economy. The shortage of monetary supplies gave rise to three economic depressions: the early years of the Qing Dynasty, Jiaqing’s reign, and Daoguang’s reign. This study clearly indicates that the scholarly debate over the “stagnation” or “growth” of the Qing economy perhaps merely depends on the period of time and aspect of the economy one examines. The two viewpoints can be somewhat reconciled. Translated by Feng Mei from Qingshi Yanjiu 清史研究 (Studies in Qing History), 2008, (3): 24–43  相似文献

Limited research has explored associations between blue spaces and mental health, specifically in children. This study assessed links between coastal proximity and depression and anxiety among children in Australia and tested whether duration of residency at current address moderated associations. It also explored associations between within-individual changes in coastal proximity and changes in depression and anxiety. Data were from 2400 children aged 11–12 years in Wave 5 (2012) and aged 14–15 years in Wave 6 (2014) of the national Longitudinal Study of Australian Children. Outcomes were children’s self-reported symptoms of depression and anxiety. Exposure was coastal proximity (<2, 2–<5, 5–<10, 10–<20, 20–<50, and ≥50 km). Linear models were fitted to examine cross-sectional associations and fixed effects models for within-individual associations. After adjustment for potential confounders, findings suggested that those living close to the coast (<2 km) had lower levels of depression than those living the furthest from the coast (≥50 km) during childhood (Wave 5) but not adolescence (Wave 6). No associations were observed with anxiety. There was weak evidence to suggest residency duration moderated associations. No associations were observed for within-individual changes. Further research is needed to understand whether and what characteristics of coastal environments may benefit children’s mental health.  相似文献

伴随着海势东迁,明代淮安府沿海荡地已出现盐场与民户相互争夺的态势,一方面是盐场为维护既有的盐利而竭力遏制沿海的农业开发,另一方面则是新淤的荡地往往吸引一批批新来的开发者。清初已淤为内陆的安东县垦荡行为在得到康熙帝首肯后,又有了进一步发展。清中期亭场商办这一市场行为也使得灶丁由制盐转向耕田,从而造成了狼在当地的绝迹。两淮盐场民众面对环境变迁积极调适生计,成为清代海州升为直隶州,庙湾、东台由盐场升格为县及清末民初"废灶兴垦"的内在动力。  相似文献

Recent archaeological investigation at the Coconut Walk site on the Caribbean island of Nevis revealed dense 40 cm deep midden deposits that accumulated between cal AD 890–1440. Analysis of invertebrate faunal remains reveals an assemblage dominated by nerite snails. We measured the length and width of more than 2700 tessellated nerite (Nerita tessellata) shells to investigate evidence for changing mean size that might be indicative of intensifying human predation pressure or other cultural and natural processes. Contrary to similar archaeomalacological studies in which size decline is detected, we observed a statistically significant size increase for N. tessellata over time. This size increase is coupled with increasing levels of tessellated nerite exploitation at the Coconut Walk site. Results suggest that tessellated nerite use was sustainable over several centuries of site occupation. Our findings have important implications for investigations of anthropogenic impacts on prehistoric mollusc populations. In addition, the findings reported here provide important insight into human subsistence patterns during the Late Ceramic Age in the Caribbean and a framework for comparison with observations from other Pre-Columbian sites in the Caribbean.  相似文献

The relationship between medicine and the arts, literature in particular, has many aspects. One of the most obvious relations is the use of literature as a source for historical studies. Jean-Martin Charcot and his school often appear in French literature at the end of the 19th century. Several aspects will be highlighted in this study, including (1) the ideas about degenerative diseases in the work of Emile Zola, the main author of the naturalistic movement; (2) decadence and spiritism in two transitional novels by Joris Karl Huysmans, who, once supporter of the naturalistic movement, changed his ideas following observations of disease and cure that could not be explained in a scientific way. Charcots work on hysteria and hypnosis, as well as Brown-Séquards rejuvenation experiments with testicular extracts played an important role with this respect; (3) Charcots relationship with the Daudets, in particular his treatment of Alphonses tabes dorsalis and the ambivalent attitude of his son Léon Daudet towards Charcot; (4) the influence of the lectures at the Salptrire on the work of Guy de Maupassant, who attended the lessons in the mid-1880s. The reading of novels and biographies of these authors provides a part of the social context and the cultural atmosphere in Paris at the “fin-de-siècle” when Charcot and his school played an important role in medicine. Moreover, it shows the influence of medicine and science on society as recorded by writers.  相似文献

A new sensitivity to the significance of historical experience has developed since the 2007 financial crisis. There are three possible ways of drawing on the past: as a source of advice on policies, of patterns of past evolution, of multiple possibilities. The best way of thinking about history is as a way of testing conventional hypotheses – particularly when those hypotheses are being used to create market opportunities (by making for false confidence; but also by engendering exaggerated despair).  相似文献

In the Pacific Northwest of North America, researchers routinely suggest changes in human use of animals explain hunter-gatherer organizational changes and development of cultural complexity. For example, most models developed to explain developing cultural complexity invoke salmon in some fashion. Yet until recently, fish remains were not carefully studied and more generally, zooarchaeological evidence has not been systematically used to test models of culture change. This study reviews the 10,000-year-old faunal record in the Pacific Northwest to test predictions drawn from models of resource intensification, resource depression and hunter-gatherer organizational strategies. The records from two subareas, the South-Central Northwest Coast (Puget Sound/Gulf of Georgia) and the Northern Columbia Plateau, are examined in detail, representing 63 archaeological sites. While minor changes in animal use are evident, the overall record is characterized by stability rather than change.  相似文献

Domestic faunal samples from farming sites from southern Africa dating from the Early (~AD 200–900) and Middle (~AD 900–1300) Iron Ages with large faunal samples are typically dominated by sheep/goats (both number of identified specimens and minimum number of individuals for large samples). However, four exceptions to this general pattern from these time periods are Bosutswe, Nqoma (both in Botswana), KwaGandaganda and Mamba (both in KwaZulu-Natal). At these sites, cattle outnumber sheep/goats, which have previously been measured using a Cattle Index. Intensive hunting is investigated at one of these sites, Bosutswe. Using various lines of evidence, including measuring high- vs. low-ranked prey, economic activities, as well as grease extraction and ageing from the most common taxon, plains zebra (Equus quagga), it is suggested that resource depression of wild game likely occurred. This would fit the expectation, based on human behavioural ecology, that as high-ranked game resource diminished over time, more emphasis was placed on cattle herding. The greater emphasis could have influenced descent patterns of people at Bosutswe. By the Late Iron Age (~AD 1300–1820s), cattle dominate most faunal assemblages in southern Africa with large sample sizes, and ethnographic and historical information confirm the central role these animals played in the social, political and economic lives of these farmers.  相似文献

河北文安、大城两县境内的文安洼,地处大清河、子牙河水系下游,地势低洼,“形如釜底”,导致积水难以泄出,历史时期常发生严重的洪涝灾害。明清时期文安县通过修筑堤防、开凿引河、营田种稻等多种措施治理文安洼,但水患仍频。文安洼水患难以治理的原因,既包括文安洼区域本身低洼的地形与大清河、子牙河下游流域淤高等环境因素,也包括文安县与周边州县之间治水利益的矛盾及文安县自身的治理乏术、乏力等社会因素。  相似文献
