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

Community‐based participatory research (CBPR) is generally understood as a process by which decision‐making power and ownership are shared between the researcher and the community involved, bi‐directional research capacity and co‐learning are promoted, and new knowledge is co‐created and disseminated in a manner that is mutually beneficial for those involved. Within the field of Canadian geography we are seeing emerging interest in using CBPR as a way of conducting meaningful and relevant research with Indigenous communities. However, individual interpretations of CBPR's tenets and the ways in which CBPR is operationalized are, in fact, highly variable. In this article we report the findings of an exploratory qualitative case study involving semi‐structured, open‐ended interviews with Canadian university‐based geographers and social scientists in related disciplines who engage in CBPR to explore the relationship between their conceptual understanding of CBPR and their applied research. Our findings reveal some of the tensions for university‐based researchers concerning CBPR in theory and practice.  相似文献

Fatal avalanche accidents in Québec (Canada) 1825 to 2009 Archival research, coroner's investigations, and newspaper searches reveal the occurrence of 43 deadly snow avalanches in Québec since 1825. Historical records indicate 73 fatalities and more than 50 injuries. Sixty percent of the victims were younger than 20 years old. More than 50 percent of the victims (38 fatalities in 12 incidents) were inside or near a residential building, usually their home, mainly in the cities of Québec and Lévis. The second‐most deadly category is recreational activities, with over 24 deaths in 20 accidents. Most of these deadly incidents occurred on very short slopes (<70 metres of relief) outside mountainous areas. Only five fatalities were related to backcountry recreational activities in highlands. The inventory of avalanche‐threatened areas has never been completed in the Province of Québec and it is likely that avalanche‐prone areas are more widespread than previously thought.  相似文献

Given the importance of contextual factors—physical, social and institutional environments—for understanding health landscapes, this article examines the situation in the province of Québec and suggests a spatial typology at the scale of the health and social services centres (CSSS). These CSSS provide services for 95 areas which are the finest territorial delineation in terms of health policies since a reform instituted in 2003. While delivery of primary health and social services is defined at this local scale, overall health policy is decided at the provincial scale. The challenge for stakeholders is to supplement their local knowledge with that of the broader context. In this article, we use principal components analysis and hierarchical cluster analysis to identify eight profiles of CSSS. The final results of the cluster analysis demonstrate that two‐thirds of the health and social services centres correspond with two marginally differentiated profiles and the remaining third shows specificities that are highly spatially anchored.  相似文献

Starting from an econometric model of local employment growth, applied to Canada (1971–2001), residuals—relative to model predictions—are analyzed over time and over space, in turn allowing us to draw a distinction between general explanatory variables and factors of a more local, cyclical or accidental nature. The model's explanatory power grows over time, founded on variables such as urban size, market access and industrial structure, allowing us to conclude that local employment growth in Canada follows an increasingly geographically predictable pattern. However, an examination of the residuals reveals more localized processes. Growth volatility is most manifest in Alberta and British Columbia, home to the most erratic local economies. Emerging patterns are visible in the last period, most notably the underperformance of Northern Ontario and of non‐metropolitan communities between Windsor and Québec City, lying along the Great Lakes and the Saint Lawrence. The over‐performance—compared to model predictions — of small and mid‐sized towns in south‐eastern Québec can, on the other hand, be interpreted as a sign of truly local social processes, generally associated with a particularly dynamic local entrepreneurial class.  相似文献

The 2012 Senegalese presidential elections engulfed the country in unprecedented controversy, violence, and protest. Urban youth in Dakar animated the massive opposition movement that eventually led to the incumbent's defeat through voter registration, public critique, and mass mobilization. Two prominent factors fomenting youth action were the direct engagement of a host of well known rappers and the pervasive power of hip hop culture. This article probes the valence of the globalized art form of hip hop as a medium of political identity formation and a language of resistance in these elections through considering the spatial practices and imaginaries of rappers and their followers. It argues that hip hop fosters new geographies of citizenship inspiring urban youth to transgress prescribed boundaries in allowed speech and political behavior to make new claims on their city and nation. Insight is drawn for understanding youth politics, the power of music, and questions of urban citizenship.  相似文献

The Province of Alberta in 2001 implemented the First Nations Gaming Policy (FNGP) to improve First Nations development potential by permitting the construction of reserve casinos. This article argues that during the policy development stages provincial and First Nations leaders failed to consider the geographic placement of reserve communities, both in terms of where casinos would be placed and how gaming revenues would ultimately be distributed. Therefore, a policy intended to assist with First Nations economic rejuvenation in Alberta has benefitted a small proportion of First Nations while exacerbating regional economic difficulties the policy was in part calculated to ameliorate. The authors recommend revisiting the FNGP to establish a more equitable revenue distribution formula, thus resulting in a greater distribution of gaming revenues to a larger number of First Nations.  相似文献

Place branding in heritage tourism development is presented as a strategy that opens up new possibilities for attracting investors and visitors by distilling, capturing and shaping what is distinctive about a place. This representational fix is an efficient marketing device in the sense that it represents places through widely intelligible symbols. Branding is also a limiting activity that locks places in time and class relations. While place branding has always had this dual effect, we argue that it has particularly insidious and limiting consequences for local development under current conditions of roll‐out neoliberalism. Beginning in the 1960s, several prominent residents and outsiders initiated efforts to transform the Town of Cobalt, Ontario, into a mining heritage tourism destination. In 2001, the town entered and won a contest to be named Ontario's Most Historic Town. The following year it persuaded Parks Canada to designate it as a national historic site. These two events provided renewed external validation for the efforts to brand Cobalt as a heritage site and began a new cycle of mining heritage tourism development. However, instead of breaking the dependency relationships that characterize resource regions, the current round of place branding has acted to circumscribe the range of possible economic development options.  相似文献

One of the significant developments in the interdisciplinary field of judgment and decision making is the classification of environments as a function of (a) their capacity to enable people to learn from experience (kind environments vs. wicked environments) and (b) the consequences of having failed to understand and adapt to them (exacting environments vs. lenient environments). Based on the premise that ‘environment’ is a key geographical concept, I explore the usefulness of appropriating these classifications in geography and argue that they can stimulate normative work on the possible contours of a better world as well as illuminate in novel ways long‐standing geographical concerns with the problematic of fairness.  相似文献

Community‐based conservation is experiencing a crisis of identity and purpose as a result of a disappointing track record and unresolved deficiencies. The latter include over‐simplified assumptions and misconceptions of “community,” the imposition of externally designed and driven projects at the community level, a focus on conservation outcomes at the expense of community empowerment and social justice, and limited attention to participatory processes. New approaches are urgently needed to address these weaknesses and to counter a rising trend towards environmental protectionism and a preference for conservation approaches at an eco‐regional scale that threaten the interests of local and Indigenous communities. We propose that three core principles of community‐based participatory research (CBPR)—(1) community‐defined research agenda; (2) collaborative research process; and (3) meaningful research outcomes—hold much promise. Drawing on the experience of a research partnership involving the James Bay Cree community of Wemindji, northern Quebec, and academic researchers from four Canadian universities, we document the process of applying these principles to a community‐based conservation project that uses protected areas as a political strategy to redefine relations with governments in terms of a shared responsibility to care for land and sea. We suggest that basic assumptions of CBPR, including collaborative, equitable partnerships in all phases of the research, promotion of co‐learning and capacity building among all partners, emphasis on local relevance, and commitment to long‐term engagement, can provide the basis for a revamped phase of community‐based conservation that supports environmental protection while strengthening local institutions, building capacity, and contributing to cultural survival.  相似文献

The uneven distribution of environmental hazards across space and in vulnerable populations reflects underlying societal inequities. Fragmented research has led to gaps in comprehensive understanding of and action on environmental health inequities in Canada and there is a need to gain a better picture of the research landscape in order to integrate future research. This paper provides an initial assessment of the state of the environmental health research field as specifically focused on vulnerable populations in Canada. We present a meta‐narrative literature review to identify under‐integrated areas of knowledge across disciplinary fields. Through systematic searching and categorization, we assess the abstracts of a total of 308 studies focused on the past 30 years of Canadian environmental health inequity research in order to describe temporal, geographical, contextual and epistemological patterns. The results reveal that there has been significant growth in Canadian research documenting the uneven distributions and impacts of environmental hazards across locations and populations since the 1990s, but its focus has been uneven. Notably, there is a lack of research aimed at integrating evidence‐based and policy‐relevant evaluation of environmental health inequities and how they are created and sustained. Areas for future research are recommended including more interdisciplinary, multimethod and preventive approaches to resolve the environmental burden placed on vulnerable populations and to promote environmental health equity.  相似文献

Questioning Québec through social geography In the early 1960s, two revolutions were underway: the quiet revolution in Québec and the quantitative revolution in geography. Apparently unrelated, these episodes of change probably shared common underlying values associated with modernity. Since then, the transformations experienced in Québec have been interpreted in a multitude of ways, including geographical considerations. Research careers, mine included, have been shaped by this undertaking. All along, I have found that social geography, with the capacity it has to reinvent itself, has helped making sense of this turbulent environment. In the 1970s, exploring the structural dynamics of Canada's social space helped in figuring out the place occupied by Québec in this ensemble. Then, analyzing the historical relationships between cosmopolitan Montréal and provincial Québec City suggested that the oxymoron ‘quiet revolution’ stood for a central process in the cultural dynamics of Québec's social space, where new ideas arriving through Montréal are sifted and institutionalized by the state in Québec City. Nevertheless, Québec City is also capable of initiating progressive urban movements, as illustrated by the odyssey of the Rassemblement populaire de Québec, documented through participant observation. Such urban movements may affect the urban fabric but, as intense and creative social networks, they may affect even more their interacting members, as it seems to have been the case with regard to rapidly evolving gender relations during the last decades. All in all, after more than four decades, I keep the conviction that a practice of social geography that is open to various theories and methods is capable of producing liberating knowledge.  相似文献
