The African continent is known by various metaphors and geographies, but for many there are also unknowns about the continent. Geopolitically, Africa is a continent that is considered remote—an economically emerging continent seen as entangled in persistent challenges of wars, political dictatorship, poverty, disease, and more recently migration. Given these predispositions it is typical to stereotype events, practice, and behaviour as “African.” There is, however, now recognition of the continent as emerging economic power house. But unpacking the diversity of Africa reveals a huge potential with respect to resource endowments, diversity of ecology, socio‐cultural economic advancement, politics, language, and demographics. Colonial history coupled with traditional Africa shaped the geopolitical boundaries that have added to the confusion about this massive and diverse continent. Intellectual discourses either amplify the differences due to specificities of geographical focus or generalizations such as the contested notion of “African.” However, using socio‐ecological lenses, Africa is unified by these very differences in addition to being a massive landmass with several big and small island states. Appreciating these differences is useful to understanding the observed patterns of social, economic, and political systems that unify the continent. This paper illustrates the notion of “African” to describe the heterogeneous nature of a “unified” continent. Some illustrative examples between Africa and other continents are used.  相似文献

For over five decades, Pictou Landing First Nation, a small Mi'kmaw community on the northern shore of Nova Scotia, has been told that the health of its community is not impacted by a pulp and paper mill pouring 85 million litres of effluent per day into a lagoon that was once a culturally significant place known as “A'se'k,” and which borders the community. Based on lived experience, the community knows otherwise. Despite countless government‐ and industry‐sponsored studies indicating the mill's pollutants are merely “nuisance” impacts and harmless, the community's concerns have not gone away. Using a “Piktukowaq” (Mi'kmaw) environmental health research framework to guide the interpretation of oral histories coming from the Knowledge Holders in Pictou Landing First Nation, we convey the deep, health‐enhancing relationship with A'se'k that the Piktukowaq enjoyed before it was destroyed, and the health suppression that has occurred since then. Conducting the research using a culturally relevant place‐based interpretive framework has demonstrated the absolute necessity of this kind of approach where Indigenous communities are concerned, particularly those facing health impacts vis‐à‐vis land displacement and environmental dispossession.  相似文献

Freeze‐thaw cycles are most common at the beginning or near the end of the winter season. These cycles have various effects on the ecosystems of Eastern Canada, affecting both biotic and abiotic components of temperate cold environments. Using air temperature minima and maxima from four meteorological stations close to Québec City, we determined the frequency of daily freeze‐thaw cycles for the last 30 years. The results show no significant increase in the number of freeze‐thaw cycles despite a small increase in air temperature. Polynomial curves describing the relationship between mean air temperatures and the number of freeze‐thaw cycles were calculated. Based on these equations and anticipating a climate change scenario, we projected future freeze‐thaw cycles. Assuming a 5 °C increase in mean air temperatures by 2100, we estimated that the number of days with a freeze‐thaw cycle could increase by approximately 20 days per winter. The increase in the number of such cycles will be concentrated during the coldest months of the winter (January and February).  相似文献

The francophone and anglophone minorities of Gatineau‐Ottawa appear to benefit from a privileged location. Living very close to their respective majorities, they simply have to cross the border in order to access resources to live in their own language and share their culture. However, a qualitative analysis of the discourse by Anglo‐Quebeckers and Franco‐Ontarians about their everyday life in the Nation's Capital Region shows that the border has more complex and often contradictory effects. In this article, we focus our attention on four particular manifestations of the border: (1) the border is transparent so that one can cross the Ottawa River without hindrance in certain contexts yet rather opaque in others; (2) one may transcend minority status through the strategic use of the border; (3) it creates a multi‐topic imaginary geography in which the border itself often becomes mobile; and (4) finally, the border can act as a mirror when the cross‐cultural intermixing it allows causes the Anglo‐Quebeckers and Franco‐Ontarians to question their identities, a questioning which would not be as intense in the absence of the border. The comparison of these two minorities makes it possible to highlight the asymmetrical nature of the effects of the border on their everyday life, identities, and sense of belonging.  相似文献

Colour measurements and non‐destructive μ‐X‐ray mappings have been used for the first time in a comprehensive study of medieval émail champlevé works from different production areas in France and Germany. This approach has given a new insight into the enamel powder preparation process of the glass material used for enamelling. Colour measurements demonstrated that all production centres used glass of very similar hues, but with large differences in colour saturation. The μ‐X‐ray mapping results of blue enamels are described by a semi‐qualitative approach. Significant variations in oxide contents of lead, cobalt, manganese and antimony oxides were found. The variations suggest that more than one glass material was used to prepare the powder for enamelling. The variations in antimony and cobalt show that glass had different degrees of opacity and colour depth. The manganese and lead contents, which do not correlate with the cobalt or antimony contents, indicate that probably glass of different base compositions was used to prepare the enamel powder for one champlevé field.  相似文献

This paper examines the role of the Ottawa Local Immigration Partnership in the Syrian refugee resettlement in Canada's national capital following the federal government's 2015–2016 resettlement plan. Based on the findings of qualitative data collection—including semi‐structured interviews with representatives from community organizations, settlement agencies, and the City of Ottawa—two main arguments are advanced. First, while the current literature tends to portray the Canadian settlement sector as a passive victim in the face of neoliberal restructuring and austerity measures, this paper offers a more nuanced perspective by reflecting on the sector's ability to exert agency by developing initiatives and devising strategies that are rooted in the local context. Second, the case of the Ottawa Local Immigration Partnership sheds light on the significance of intersectoral networks and partnerships that extend beyond the settlement sector to build a sound approach for welcoming refugees and newcomers more generally. These findings serve to demonstrate the potential of partnerships as a place‐based settlement model that is responsive to context‐specific needs and enhances local community strengths, thus providing important lessons that can inform future immigrant and refugee (re)settlement and integration in other Canadian cities and regions.  相似文献
