Climate change and resource development interact to have significant impacts on both natural and human systems within watersheds. It is, however, difficult to conceptualize and communicate these intersections, as climate change and resource development are each independently uncertain and complex. We facilitated a process whereby stakeholders created plausible future scenarios for the Nechako Watershed in British Columbia, Canada. This region is reliant upon, and has been significantly affected by, many types of resource exploitation. During a full-day workshop, 32 stakeholders created scenarios for 2050 envisioning high and low levels of both resource development and climate change. The high and low levels of climate change were based on downscaled projections from global emissions scenarios, and the resource development levels were determined at the beginning of the workshop by the participants. The exercise was educational, and motivated stakeholders to conceptualize plausible future changes and their impacts, and the outcomes should motivate stakeholders to work towards realizing a more desired future. All scenarios (even low-low) were deemed to have significant negative impacts, suggesting that the Nechako Watershed is in a vulnerable state. The complexity of the exercise suggests that more capacity building may be necessary. 相似文献

Geographically weighted quantile regression (GWQR) has been proposed as a spatial analytical technique to simultaneously explore two heterogeneities, one of spatial heterogeneity with respect to data relationships over space and one of response heterogeneity across different locations of the outcome distribution. However, one limitation of GWQR framework is that the existing inference procedures are established based on asymptotic approximation, which may suffer computation difficulties or yield incorrect estimates with finite samples. In this article, we suggest a bootstrap approach to address this limitation. Our bootstrap enhancement is first validated by a simulation experiment and then illustrated with an empirical U.S. mortality data. The results show that the bootstrap approach provides a practical alternative for inference in GWQR and enhances the utilization of GWQR. 相似文献

Abstract. Accusations of Albanian rape of Serbs in Kosovo became a highly charged political factor in the development of Serbian nationalism in the 1980s. Discussions of rape were used to link perceptions of national victimisation and a crisis of masculinity and to legitimate a militant Serbian nationalism, ultimately contributing to the violent break‐up of Yugoslavia. The article argues for attention to the ways that nationalist projects have been structured with reference to ideals of masculinity, the specific political and cultural contexts that have influenced these processes, and the consequent implications for gender relations as well as for nationalist politics. Such an approach helps explain the appeal of Milo?evi?'s nationalism; at the same time it highlights the divisions and conflicts that lie behind hegemonic gender and national identities constructed around difference. 相似文献

This study examines the abilities of different types of governments to take proactive steps towards reducing pollution. Specifically, the hypothesis that the system of interest group representation on a scale of pluralism to corporatism will affect a state's rate of change to reduce consumption of carbon dense fuels. Using a standardized measure of carbon density of fuels consumed, this work examines industrialized economies over a 13-year time period. The study shows that the Nordic corporatism systems are more capable of shifting to cleaner fuels than pluralist, majoritarian systems. It is asserted that this is a result of the goal-oriented policymaking in corporatist states in comparison to more process-oriented policymaking in pluralist systems. 相似文献

It took several decades for sex workers to become true speakers,rather than testifiers to the speech of others. Tensions understandablyremain about sharing authority with oral historians. This articlereflects on attempts to share authority in setting up, funding,organizing, and publishing from a UK sex work project. It questionswhether commitment to share authority compromises scholarshipand theoretical development, and how an oral historian's roleis affected by a parallel advocacy role. It explores the formationand boundaries of collaborative relationships and briefly raisesthe issue of crossing legal boundaries in less orthodox projectwork and implications for ethical permissions. 相似文献

The number of sale transactions recorded by northern Spanish charters of the tenth century is very striking, especially in the 930s to 960s. A record of price paid was a consistent element of such documents, although words used to express price varied from silver solidi to goats, shirts and grain. Valuations, in solidi and in other units of account such as cattle, were often stated when objects were used as payment. While it looks as if some silver was really used in deals in urban León and its hinterland, using pieces of silver called argenzos , argenteos etc., elsewhere this was rare. Comparing the transactions in the three very different monastic collections of Celanova in the north–west, Sahagún in the central meseta and Cardeña in the foothills of the sierras in the north–east, regional difference is also striking. Sahagún is notable for the volume and early date of its sales and for increasing use of silver–based expressions of price and value. Round Celanova, by contrast, although there were also many sales, people used several modes of valuation simultaneously, but metal–based notions very rarely. Round Cardeña, close to urban Burgos, far fewer sales are recorded, and they come later in the century, but silver–based notions of value were the only ones used. This latter sub–urban context seems to have been much less commercially active than that of León and Sahagún, with exchange by gift and countergift a more prominent characteristic. 相似文献

Gayle MacDonald (a sociologist) and Leslie-Ann Jeffrey (associateprofessor of history and politics) interviewed sixty sex workersin three cities in the Maritimes region of Canada: Halifax,Saint John, and Moncton, as well as some police, health, andcommunity workers and politicians. This book presents in-depthextracts of those interviews, with a commentary drawing on criticalpolitical analysis. It is not an oral history book per se. Butit skillfully blends these oral sources with a thorough critiqueof a range of good sex work literature. In common with mostother sex work oral history, the authors take an explicit andacknowledged stance that draws on the insights of sex radicalismand pro-rights feminism, 相似文献

Contemporary prostitution policy within the European Union has coalesced around the view that female prostitution is rarely voluntary, and often a consequence of sex trafficking. Responding, different nation-states have, however, adopted antithetical legal positions based on prohibition (Sweden), abolition (UK) or legalisation (Netherlands). Despite the apparently sharp differences between these positions, in this article we argue that there is now a shared preoccupation with repressing spaces of street prostitution. Noting the forms of exploitation that nonetheless adhere to many spaces of off-street work, we conclude that the state and law may intervene in sex work markets with the intention of tackling gendered injustice, but are perpetuating geographies of exception and abandonment. 相似文献
