Work hard, play hard: selling Kelowna, BC, as year-round playground   总被引:1,自引:1,他引:0  
A keen interest in place making and place selling is widespread in contemporary society. While the bulk of academic research has focused on studying the restructuring of large urban conglomerates, places beyond the exploding metropolis, by comparison, have received little attention, especially when it concerns Canadian landscapes. In an attempt to study the particularities of place making in contemporary smaller, more isolated communities—hinterlands—this work analyses the city of Kelowna, in British Columbia, Canada. We argue that historically Kelowna, a small rural community specialising in ranching, forestry and fruit production, since the early 1980s, has been re-imagined and re-designed, on the one hand as an all-year playground and as an innovative frontier for high-tech industries; on the other hand, this post-Fordist reinvention contains a discourse of 'whiteness', one that entices by packaging 'place' in terms of 'sameness' and 'familiarity'. In contrast to large cosmopolitan post-industrial cities, hinterland-type cities are invented, sought and lived as geographies cleared from the 'elements' that make cities 'unsafe'.  相似文献

ABSTRACT The productivity effects of agglomeration economies are often treated as endogenous in empirical work due to the potential for reverse causality. The extent to which these relationships are actually simultaneously determined, however, remains largely unobserved. This paper estimates panel data vector autoregressions for different sectors of the economy to test for bidirectional causality between productivity and both localization and urbanization economies. The aim is to address some key questions that will help to identify the extent of the endogeneity problem. Can we actually observe bidirectionality in the data? Does it feature more for some industries than for others? Is it more prevalent for localization or urbanization economies? The results show that agglomeration economies are not strictly unidirectional and that higher levels of productivity can induce growth in the scale of local urban and industrial environments. The paper discusses the difficulties that these issues pose for the estimation of agglomeration economies.  相似文献

Mexico’s Central Highlands form one of Mesoamerica’s fundamental cultural seams, a point of overlap between two traditions, one to the east and the other to the west. Although this area is usually included in the west, it can be more productively viewed as an interface, the physical space where people, goods, and ideas passed from one side to the other, and thus it holds many keys for our understanding of emerging social complexity in Mesoamerica. In reviewing the last two decades of Formative period (1500 BC–AD 100) research in this crucial territory, we focus on themes that reveal the variation and dynamism of interregional interaction, including the formation of regional traditions, exchange systems, and foreign “influence,” and others that help contextualize the events and processes of that time, like household studies and environmental degradation. We stress that this part of Mexico is undergoing relentless development so time is of the essence if we are to broaden our perspectives on social evolution in the Central Highlands. This issue cannot be resolved by rescue and salvage work because it requires long-term, interdisciplinary projects to unravel multifaceted problems.  相似文献

In Picturing Heaven in Early China,a consideration of the symbolism of Heaven in early Chinese culture,Lillian Lan-ying Tseng examines the evolution of a pictorial language for the expression of "religious" ideals.By analyzing the architectural,material and literary evidence from the Han dynasty,the author traces the trajectory of Han thought from its first concerns with the notion of Heaven and the involvement of the emperor,to the growing desire for personal immortality at all levels.The book comprises five chapters,which plot the development of Han thought and images of heaven.This is a complex and well-researched examination,whose depth and detail can only be suggested here.  相似文献

Situated within the political ecology of hazard, this article is an extended case study of the devastating 2003 wildfires in and around Kelowna, British Columbia (also known as the Okanagan Mountain Park Fire). This article reveals how compliance (or lack thereof) with fire mitigation strategies recommended by provincial, regional, and municipal agencies is complicated by differing social constructions of what constitutes ecologically sustainable forest management and community safety. Three perspectives emerge regarding the urban forests: “nature as hazard”—a volatile force to be controlled; “nature as instrumentally valuable”—a contribution to the character of one's surroundings and subsequent sense of place; and “nature as intrinsically valuable”—a distinct entity to be preserved and protected for its own sake. The article also examines how experiences of disaster influence community perceptions and result in a greater willingness to engage in fire mitigation strategies due to perceptions of heightened vulnerability. Forestry and fire mitigation agencies need to determine multiple courses of action among the varied and valid range of residents’ nature perspectives. The role of human agency in disaster mitigation must be examined, particularly as the risk of fire at the wildland‐urban interface continues to be exacerbated by encroaching human settlements and climate change.  相似文献
