Scientists advise limiting global warming to 1.5°C with substantial actions by 2030. Our viewpoint argues that climate response strategies in Canada have underemphasized and underestimated the potential contribution deep energy retrofits can make to greenhouse gas (GHG) emissions reductions, leading to inadequate responses in the building sector, and that Canada can (and should) be ambitious with building retrofits over the next decade. GHG savings from building retrofits can be realized more quickly than GHG reductions from other sectors, and either deliver net cost savings or are cost‐effective when compared to other mitigation measures. Retrofits can also provide social and economic benefits, such as improved health and comfort, and lower energy costs. This paper reviews energy use and building retrofits in Canada and argues the following should be implemented: (1) focus innovation on deep energy retrofit processes, not singular retrofit actions; (2) maximize both social and environmental benefits; (3) improve data gathering and availability for analysis and delivery; (4) innovate for a process of decisions and to avoid “dropouts” during the retrofit process; and (5) focus innovation on business models that maximize benefits.  相似文献

A new generation of greenways has emerged in recent years, the most ambitious of which are nationwide, interconnected networks of multi-use, multi-purpose greenways and trails, clustered under a single national vision. However, because these initiatives have been the focus of so few research studies, opportunities to glean lessons from their planning and implementation have been limited. This paper contributes to addressing this knowledge gap by presenting a comparative account of two networks, the Trans Canada Trail in Canada and Sendero de Chile in Chile. Using document analysis and interviews with officials closely involved in their development, the evolution of both networks is documented over time, emphasizing similarities and differences related to their planning and implementation. Both initiatives have faced significant challenges in reaching their connection goals and have availed themselves of a diverse range of opportunities and strategies to advance their agendas. A simple model of a virtuous cycle is proposed to highlight the positive feedback—between political and public support, sustained funding, partnership development, accessibility for urban residents, and connectivity of the network—generated by sustained network expansion over time. It is hoped that the insights offered from this analysis may offer guidance to inform the development of similar scale projects elsewhere.  相似文献

This article explores the ‘more-than-work’ aspects of the lives of vulnerable women who street-sex work. Particularly, we are interested in the differences between the women’s experiences, within the broader context of power structures as manifested in neoliberal cities. Few studies have explored this aspect of street-sex workers’ lives and theorisations of the co-creation of environments tend to elide the experiences of the most vulnerable people. Specifically, we explore the relationships that these women have with two environments: the quotidian (where they undertake routine everyday activities), and the gentrified (relating to changes in the spaces in which they live and work). We find that their experiences are extremely local, and heavily contingent on the services made available to them (or not) by the statutory and third sectors, and the emotional contacts they make, particularly in third sector support services. This challenges some of the literature which suggests a separation of ‘home’ and ‘work’, and which finds close associations between women who street-sex work. While places designed by the third sector are more responsive to these women, they are also more vulnerable to closure through lack of funding. This contributes to a significant degree of ontological non-linearity and ontological insecurity in these women’s lives.  相似文献

Using data from Canada’s General Social Survey, this article assesses ethno-racial differences in social trust. Bivariate findings reveal that the three most culturally distinctive minorities—visible minorities, the French, and Indigenous Peoples—exhibit the lowest trust of all groups. Multivariate analyses show that controls for “ethno-cultural markers” (religion, language, immigration status), socioeconomic influences (education, income), and social engagement indicators (voluntary association activity, ethnic diversity of friendships) explain the lower trust between the French and, less so, among visible minorities. Socioeconomic factors partly account for lower trust among Indigenous Peoples, but they still express comparatively low social trust even with controls. The article discusses how interpretations focusing on “social distance” and “social boundaries” processes help in understanding social trust differences across Canada’s major ethno-racial communities.  相似文献

This article introduces latent trajectory models (LTMs), an approach often employed in social sciences to handle longitudinal data, to the arena of GIScience, particularly space‐time analysis. Using the space‐time data collected at county level for the whole United States through webpage search on the keyword “climate change,” we show that LTMs, when combined with eigenvector filtering of spatial dependence in data, are very useful in unveiling temporal trends hidden in such data: the webpage‐data derived popularity measure for climate change has been increasing from December 2011 to March 2013, but the increase rate has been slowing down. In addition, LTMs help reveal potential mechanisms behind observed space‐time trajectories through linking the webpage‐data derived popularity measure about climate change to a set of socio‐demographic covariates. Our analysis shows that controlling for population density, greater drought exposure, higher percent of people who are 16 years old or above, and higher household income are positively predictive of the trajectory slopes. Higher percentages of Republicans and number of hot days in summer are negatively related to the trajectory slopes. Implications of these results are examined, concluding with consideration of the potential utility of LTMs in space‐time analysis and more generally in GIScience.  相似文献

India’s recognition of West, but not East, Germany was the foundation of an inconsistent policy on Germany from India and many other non-aligned countries. It was the outcome of a lack of professionalism, indecisiveness, the pragmatic considerations of a junior Indian diplomat in Berlin, and the laconic approval of the anti-communist secretary-general of the Ministry of External Affairs, Girja Shankar Bajpai. Neither Prime Minister Jawaharlal Nehru nor his advisor V.K. Krishnan Menon were involved at all. Officials around Foreign Secretary K.P.S. Menon held that the GDR should also be recognised in due course, but did not exercise sufficient influence. India would stand by its decision for 23 years and thereby set an example for other non-aligned countries.  相似文献

Scholars have been studying the concept of public engagement and its role in the policy process for some time. Scholars have argued that understanding the interests and motivations of the public and engaging them in the decision‐making process can lead to better policy designs and, ultimately, better policy outcomes. However, studies of public engagement often assume that people have a desire to get involved in the policy process. This paper tests this key assumption using the case of nuclear facility siting in the United States to ask: what factors influence an individual's stated willingness to want to engage in the policy process? Using data from a national web survey fielded in 2013, we ask the public if and to what extent they would likely engage in the siting process if given the opportunity. Findings indicate that the likelihood of engagement varies rather substantially across individuals. We find that an individual's cultural belief system and existing level of political activity account for some of this variation. These findings suggest that public engagement programs may vary across groups and communities. In other words, the prospects of engagement are likely to appeal to some members of the population and not others.  相似文献
