Extreme weather events in northeastern New Brunswick (Canada) for the period 1950–2012: Comparison of newspaper archive and weather station data 下载免费PDF全文
In the context of global warming, changes in extreme weather and climate events are expected, particularly those associated with changes in temperature and precipitation regimes and those that will affect coastal areas. The main objectives of this study were to establish the number of extreme events that have occurred in northeastern New Brunswick, Canada in recent history, and to determine whether their occurrence has increased. By using archived regional newspapers and data from three meteorological stations in a national network, the frequency of extreme events in the study area was established for the time period 1950–2012. Of the 282 extreme weather events recorded in the newspaper archives, 70% were also identified in the meteorological time series analysis. The discrepancy might be explained by the synergistic effect of co‐occurring non‐extreme events, and increased vulnerability over time, resulting from more people and infrastructure being located in coastal hazard zones. The Mann Kendall and Pettitt statistical tests were used to identify trends and the presence of break points in the weather data time series. Results indicate a statistically significant increase in average temperatures and in the number of extreme events, such as extreme hot days, as well as an increase in total annual and extreme precipitation. A significant decrease in the number of frost‐free days and extreme cold days was also found, in addition to a decline in the number of dry days. 相似文献

Following the exceptional discovery of Neolithic engravings on a boulder at Vallée aux Noirs in the Fontainebleau forest, south of Paris, an excavation trench was opened in order to access the buried part of the decorated rock panel and explore the stratigraphic context of the artwork. A palaeosol was found two metres below the modern ground level, underneath multiple layers of sterile sandy soil forming a very compact sequence from which only one archaeological artefact was recovered – an Iron Age fibula (c.200–300 BC). Dating of the palaeosol was attempted through two different methods: AMS dates from charcoal suggest a significant span from the Early Bronze Age to the Iron Age, while two more consistent OSL dates point to formation of the palaeosol during the Late Neolithic (3500–3000 cal BC). The entire engraved rock surface (16 m2), including its buried part, was fully recorded. Four main semiotic groups were identified: a typical fifth‐millennium crook‐hafted axe with a ring, two boats with steering oars, and a central, very tall human figure dominating the composition from its 3.5‐metre height. 相似文献

Quiet urban areas are places with low noise levels that can help people to support physical and mental wellness. This paper has two objectives: to identify quiet urban areas in Montreal and to check for the presence of environmental inequities in access to such areas for vulnerable groups (children, older people, low‐income individuals, and visible minorities). Using a GIS‐based methodology, 2,282 quiet urban areas were identified in Montreal. The results of a mixed effects logistic regression model analysis showed that there are no major inequities in access to quiet urban areas for the population groups studied. The analysis did, however, revealed substantial spatial disparities in terms of the distribution of quiet urban areas across the boroughs and municipalities examined. 相似文献

The aim of this paper is to shed light on the importance, for cultural history, of a professional concept from the publishing worl, for example « general literature » - a concept which goes against most of the usual forms of classification and division of intellectual output. Through the use of an « indigenous » source from within the publishing domain such as the advertisement notices published in Bibliographie de la France, one can show the coherence of a wide domain which encompasses - but also widely surpasses - the boundaries of literature as commonly conceived. As one category of publishing output, general literature can be characterized during the first half of the XX th century by the use of the same material form the 12mo whose profound significance is the intention to reach a « wide educated audience ». Thus, it is by taking into account the structure of this output that, through such a domain as general literature, the publishing market allows the question of the actual existence and aspects of learned culture to be raised. 相似文献

ABSTRACTWith the increasing commodification of cultural heritage induced by tourism development, the perception of a ‘real’ travel experience often depends on what is defined as authentic, original and local. Visitors are becoming increasingly concerned about the authenticity of eco-cultural tourism practices when they visit culturally and environmentally remote regions. The purpose of this study is to examine the role performance plays in visitors' perception of authenticity of eco-cultural tourism experiences. Various theoretical foundations and aspects of visitors' perceptions of authenticity in cultural heritage tourism are considered. A grounded theory approach based on in-depth semi-structured interviews with several categories of visitors including 25 clients from two eco-tours in South and Central Kazakhstan and 29 Free Independent Travellers (FITs) was adopted to identify visitors' perception of authenticity of various aspects of their tourism experiences and the attributes of the visitors' performative aspects of their travels. Results reveal that the performative aspects contributing to the perceived authenticity of the visitors' eco-cultural experiences are spontaneous, existential and reciprocal relationships with their hosts in intimate tourism encounters. The findings contribute to literature regarding authenticity and cultural heritage tourism by exploring new directions in which to apply the concept of authenticity in eco-cultural tourism experiences and by theorising the link between performance-based touristic space and the perception of authenticity. This space becomes a basis for interaction and social exchange within the host–guest relationship. 相似文献
