This study uses service area–based coverage and various count regression methods to assess neighbourhood-level healthy and unhealthy food environments, and food access associated with different socio-economic groups in Edmonton, Canada. We identify three types of vulnerable neighbourhoods according to different food environments: food deserts (i.e., neighbourhoods lack sufficient access to healthy foods); food swamps (i.e., neighbourhoods have excess access to unhealthy foods); and those with overlaps of food swamps and food deserts. We also identify neighbourhoods with superior access to healthy foods (i.e., food oases). Additionally, our results from regression analyses indicate: (1) child population is negatively associated with both healthy and unhealthy food resources; (2) good access to public transportation is associated with good coverage of all healthy food outlets and convenience stores; and (3) deprived neighbourhoods with higher percentages of minority populations have better coverage of both healthy and unhealthy foods in general. The results from this study can help the City of Edmonton identify the key neighbourhoods with high potential for local business and the hotspot neighbourhoods that require particular support. Tailored strategies are proposed to effectively and efficiently improve food environments with limited resources.  相似文献

The concept of “advocacy coalitions” is the bedrock of the Advocacy Coalition Framework (ACF), one of the most established and successful approaches for understanding policy processes across the globe. This article revisits and sharpens the conceptual definition of advocacy coalitions. We summarize the lessons from its theoretical emphases under the ACF and specify its five attributes (policy actors, shared beliefs, coordination, resources, and stability). Through this specification, we identify the ideal coalition type and several coalition subtypes. We then clarify and make a distinction between how we think about coalitions as a concept and how we approach coalitions empirically. This article sharpens the lens for describing and explaining coalitions toward better observations, theorizing, and measurements. It ends with next steps for further deepening and broadening knowledge about advocacy coalitions.  相似文献

Writing The History of the Sevarambians in the 1670s, the Huguenot Denis Veiras borrowed many ideas from Garcilaso de la Vega, also known as El Inca, whose Royal Commentaries of the Incas was published in 1609. Both works describe the history of an empire and justify it on the ground that it brought peace and unity. While Garcilaso’s book purported to be a history, his selection of facts reflected his goal of improving the treatment of the Incas by the Spanish. Veiras’s story also claimed to be a history, but it was transparently a fiction, even to the point of lifting many elements from Garcilaso’s book. What both works equally emphasized was that empires could aim at, and could be justified by, the benefits they provided their subjects. Both tell stories of benevolent and paternalistic rulers who founded nearly ideal societies in the countries they conquered. These were models of empire for peace and unity rather than merely promoting toleration of differences or concord among differing parties. Veiras’s utopia thus offers an instructive case study of the effects of cross-cultural borrowings of literary and political ideas.  相似文献

Zoos and aquariums are responding to the worldwide biodiversity crisis through major conservation initiatives like captive breeding for assurance populations and reintroduction programs. These institutions also fundraise, offer education programs, and provide critical research on biodiversity. Through a case study inside three accredited Canadian zoos, this paper illustrates that zoos and their staff members are being incorporated into many official species‐at‐risk recovery efforts on provincial, federal, and international levels. Specifically, the zoos studied are involved in every stage of the recovery process, from providing valuable research and habitat analyses, to captive breeding animals for reintroduction, to writing recovery strategies and creating recovery policy for multiple jurisdictional levels. Zoo staff indicate that zoos are uniquely suited to conservation because zoos have space, expertise, apolitical status, and the ability to connect with the public. Overall, the paper suggests that zoos can significantly contribute to species‐at‐risk protection and recovery in Canada and beyond.  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

Este artículo propone una lectura de la Historia del Reino de Quito en la América Meridional (1789), de Juan de Velasco, a partir de las ideas políticas y jurídicas de su autor. Sugiere abordar el tomo tercero de la Historia no solamente como un relato del declive social y económico que aqueja a la Audiencia de Quito, sino como un comentario a la crisis de gobernanza que, según Velasco, inicia con el ascenso de los Borbones al trono. La incapacidad jurídica de controlar la mestización de la sociedad y las desacertadas políticas de las autoridades peninsulares, resultan en la Rebelión de los Barrios de Quito, episodio que representa el clímax de las penurias que atraviesa el Reino y que le permite a Velasco cuestionar el modelo de gobierno establecido por los reformistas ilustrados, abogar por la necesidad de un gobierno criollo y restaurar la desgastada imagen de la Compañía de Jesús.  相似文献

This article compares different historical accounts of early Christianity written by François Guizot, Benjamin Constant and Madame de Staël and shows that they played a significant role in the construction of their ideas about religious tolerance and political liberty in ancient and modern states. In his 1812 translation of Gibbon’s Decline and Fall of the Roman Empire Guizot used his editorial footnotes to oppose Gibbon’s sceptical representation of the early Church and to assert that the development of Christianity had been crucial in condemning slavery, establishing religious toleration and fostering individual liberty. Benjamin Constant also opposed Gibbon’s representation of early Church history but he argued in his posthumously published Du polythéisme romain (1833) that the key achievement of the early Christians had been to revive the idea of individual religious sentiment against the anti-individualist Roman state. As Guizot developed his historical research in the 1820s he rejected this view and came to see the early Christians as demonstrating the inherently social nature of all religious practice. Some of these ideas were anticipated by Madame de Staël in De la littérature (1800), but all three thinkers sought to reintegrate religion into their ideas of modern liberty in ways that merit greater attention.  相似文献
