Schlichtman and Patch suggest that there is an elephant sitting in the academic corner: while urbanists often use ‘gentrification’ as a pejorative term in formal and informal academic conversation, many urbanists are gentrifiers themselves. Even though urbanists have this firsthand experience with the process, this familiarity makes little impact on scholarly debate. There is, Schlichtman and Patch argue, an artificial distance in accounts of gentrification because researchers have not adequately examined their own relationship to the process. Utilizing a simple diagnostic tool that includes ten common aspects of gentrification, they compose two autoethnographic memoirs to begin this dialogue.  相似文献

The research studies empirically the role that fairness plays in shaping emotional and behavioral forgiveness among older U.S. consumers (55 years of age and older). A theoretical model is proposed and tested that proposes, consistent with theory on emotions, that perceptions of justice affect behavioral forgiveness through emotional forgiveness. An alternative theory questions whether the effects of justice are totally mediated by emotion. Comparative results support the latter model. The cognitive perceptions of justice display a stronger effect compared to the mediated effect through emotional forgiveness. Additionally, an examination of moderation by psychological age suggests that relatively old and young (psychologically) consumers react in the same manner. While clearly, service managers need to be sensitive to the emotions of senior customers, the results here suggest a stronger role for cognitive perceptions of justice. Thus, service providers need to provide senior consumers with clearly understandable explanations for any service failure and explain how the recovery efforts will compensate for the failure.  相似文献

适应节能形势发展的新变化,能耗监测的内涵也正在逐步延伸。实践表明,建立有效的能耗监测管控体系,对于提高能效、推进节能减排作用明显。近年来我国能耗监测管理得到了不同程度的改善,但在管理理念、制度安排、技术创新、资金支持等方面还存在着较多问题。利用信息技术,建立能耗在线实时监测管理体系,将成为未来能耗监测的发展目标。适应这种发展要求,我国需要在计量设备基础管理、能耗监测考核制度、监测机构设置和人员培训、资金渠道等方面进行不断创新。  相似文献

Estimation of ecosystem service values is a hot area of research in ecological conservation and economics. However, the costs of these outputs are largely unknown. In this paper, we estimated the opportunity cost of water allocated to afforestation projects through mathematical modeling based on statistical data for all of China to provide support for restoration planning based on a fuller consideration of the true costs. To guide future ecological conservation and environmental policy development, we illustrate a neglected concept (ecosystem service costs) and use this concept to compare the ecological services provided by ecological restoration based on afforestation with those of restoration based on the conservation of natural vegetation using data obtained since 1949 in China. The results showed that afforestation and natural vegetation create annual costs related to use of the available water resources equal to 4800 and 3700 RMB ha−1, respectively, representing a water opportunity cost of 1100 RMB ha−1 for afforestation. This illustrates the rule that “there is no free lunch” for any service, including ecosystem services. Therefore, to support the development of more effective and sustainable environmental restoration policy, it will be necessary to evaluate the associated opportunity costs.  相似文献

2013年我国人均GDP达到6900美元,标志着我国已居于“上中等收入”国家行列,正面临“中等收入陷阱”的威胁。本文基于日本、韩国、巴西和阿根廷的发展历程,考察了“中等收入陷阱”区间下消费率的变化轨迹,认为成功跨越“中等收入陷阱”的消费率特征是:消费率走势呈U型特征,由波动性变化演变为平稳性运行,并大致在人均GDP4000美元形成“消费率拐点”。其中,收入因素对“消费率拐点”的培育与形成具有较大的制约作用。同时文章对比分析了低中等收入阶段我国消费率变化轨迹,认为我国在人均GDP4283美元水平下形成“消费率拐点”,但当前消费需求的充分释放仍面临较强的挑战,迫切需要相应的政策措施来强化“消费率拐点”的形成。  相似文献

Soil is a natural resource essential to human welfare by virtue of its numerous crucial functions. In the past, soil has been taken for granted because of its widespread, albeit finite, availability. However, now that world's population is projected to exceed ten billion before the end of this century, soil is increasingly perceived as a precious commodity. Consequently, soil is increasingly under pressure by rich private investors and governments within the poorest countries to satisfy appetites for food production and biofuel. A case study is used to explore the plausibility of soil being considered as ‘brown gold’. Based on the comparison of land use maps, we estimated the value in terms of resource from raw material, carbon sink and virtual calories of the productive soil lost during the period 2003–2008 in the Emilia-Romagna Plain, one of the most productive areas of Italy. More than fifteen thousand hectares of cropland underwent land use change – in particular urbanization – over the 6-year period with an implied loss of crop production potential equivalent to the daily calorific requirement of more than 440,000 people. Taking into account that Italy is no longer self-sufficient in food production, such a loss appears to be strategically significant. Perhaps more importantly, urbanization and soil sealing has had negative ramifications on environmental sustainability, on both local and broad scales, with increased consumption of public funds. A logical framework of the socio-economic impact of land use change has been compiled and is presented as a possible example of a policy relevant approach to managing productive soils as a finite resource.  相似文献
