Canada’s climate change strategy faces an uncertain future since the country’s withdrawal from the Kyoto Protocol in 2011, making domestic public debate and awareness critical in the search for effective mitigation policies. This article presents a spatio-temporal analysis of newspaper reporting across Canada on climate change and carbon reduction approaches, ranging from renewable energies (solar, wind, hydro power) to carbon management (e.g., carbon capture and storage [CCS]) and economic approaches (e.g., carbon trade, ecological fiscal reform). The findings of a news article keyword analysis show that the overall growth of the Canadian news coverage during this time period was significantly fragmented into isolated peaks of activity rather than continuous growth of the topic of climate change. Furthermore, the study finds a strong news emphasis on technology- and growth-oriented solutions as opposed to a comprehensive ecological modernization that would encourage a deeper structural discussion about Canada’s much-criticized carbon-intensive energy economy.  相似文献

Abstract

Anthropologists Niko Besnier, Susan Brownell, and Thomas Carter have recently contributed a theoretically- and empirically-updated account of sport anthropology, the burgeoning, heterogenous, productive field dedicated to the myriad forms of sport and physical activity in human societies. This essay dialogically relates their contribution with previous conceptions of sport anthropology to better understand the interconnections between global and local contexts of physical culture and the relations between anthropological inquiry and important issues like social power, biopolitics, and colonialism. The essay specifically highlights the authors’ contextualization of assumptions of modernization and categorizations of “primitive” and “pre-modern” sport, arguing that a postcolonial approach to sport anthropology results in a more inclusive, nuanced framework for studying the anthropological dimensions of physical culture.  相似文献

Conservative Party leader Stephen Harper campaigned in 2006 that, if elected, his government would make major improvements to Canada’s military. Emphasizing the decline that had befallen the once proud institution under the Liberals, Harper spoke of the spending increases and new capabilities that would result if his party emerged victorious in the upcoming vote. Seven years later, and two years after the prime minister was finally rewarded with a majority government, it seems like an opportune time to examine the Harper defense record. The article will show that defense spending has increased and a string of new equipment projects have been announced. However, the article will also reveal that the spending increases are almost certainly over, while few of the capital programs are actually progressing. Thus, the Harper defense record is ambiguous, and does not constitute the dramatic change that was promised.  相似文献

对中国社会改革开放重要意义的认识应置于现代化与中国特色社会主义相统一的视野中。无论是对改革开放历程的总结,还是对中国特色社会主义道路的认识,都必须基于中国社会现代化道路的曲折探索过程。唯有从这三个方面且将三者有机地联系起来进行全面认识,方可实现对改革开放历史作用的深刻判断。  相似文献

A large network of exceptionally well-engineered prehistoric canals has been discovered near Safford, Arizona. Within an area of roughly 450 km2, 12 distinct canal systems, comprised of 41 canals, have been identified originating in the bajada of the Pinaleño Mountains. Conveying water from runoff and springs, the longest canal is about 13?km, and the total length of all systems exceeds 125?km. While a few canals may date to ca. a.d. 1100, the vast majority date to between ca. a.d. 1250 and 1450 and appear to be constructed by migrants from northeastern Arizona. These features represent the second largest network of canal systems in the American Southwest, and, while smaller in size and total length than the canal systems of the Phoenix Basin, they exhibit engineering sophistication not found in those systems. These canals have expanded the knowledge of prehistoric water management engineering and agricultural intensification in the American Southwest.  相似文献

Methods are described for modelling both the speeds and the driving forces of innovation processes, namely Critical Path Schedules and Cash Flow Curves respectively. The differences between innovations in modern industrial conditions and simpler societies are discussed, and the models applied to early innovations, but the data are too fragmentary to make quantitative models, although they can be used qualitatively to show general trends. In early societies the speeds were very slow but benefit/cost ratios very high, whereas the reverse tends to be true on average for modern innovations. Long delay times are often found in early innovation processes and these are determined by a wide variety of cultural factors. Seldom has the progress of the technology itself been on the “Critical Path” of innovation processes. The “Critical Path” and “Cash Flow” methods can also be used to study other, non-innovative, complex processes.  相似文献

As economic and ecological crises evolve in combination, some policy strategies might aim at killing the two birds with one stone. One recent example can be found in Malmö, Sweden, where crisis management has operated, we propose, as a green fix. The district of Västra hamnen (Western Harbour) is at the centre of the reinvention of the city: once the home of a world‐leading shipyard, it is now a no less prominent neighbourhood of ecological virtues. Through outlining the history of Malmö in general and the Western Harbour in particular, we identify how the municipality and local capital in concert increasingly used “green” strategies in the urban policies that started as crisis management in the 1990s. Today Malmö is reckoned to be among the world's greenest cities, and we reflect on the importance of this international recognition for the city. Finally, we develop a critique of the green fix as concealing crucial factors of scale, and hence running the risk of myopia.  相似文献
