进入20世纪90年代以来,旅游影响以及居民对旅游发展认知态度的研究开始逐渐聚焦于研究尺度与研究方法上,旅游影响态度尺度就是在这种背景下被开发出的一种用以测量目的地居民对旅游发展态度的工具。尽管在国外它已经引起学术界的广泛关注,但是国内还鲜有学者对此进行研究。因此,本文以实证研究的方式,在中国广西的阳朔地区进行实地调查,并采用因子分析的方法对数据进行了分析,以验证西方学者所提出的旅游影响态度尺度在我国的适用性。  相似文献

Human geography without scale   总被引:14,自引:0,他引:14  
The concept of scale in human geography has been profoundly transformed over the past 20 years. And yet, despite the insights that both empirical and theoretical research on scale have generated, there is today no consensus on what is meant by the term or how it should be operationalized. In this paper we critique the dominant – hierarchical – conception of scale, arguing it presents a number of problems that cannot be overcome simply by adding on to or integrating with network theorizing. We thereby propose to eliminate scale as a concept in human geography. In its place we offer a different ontology, one that so flattens scale as to render the concept unnecessary. We conclude by addressing some of the political implications of a human geography without scale.  相似文献

Abstract: Recent years have witnessed increased geographical interest in the changing nature of forestry in the UK. Critical attention has been given to a transition from a previously dominant regime of industrial forestry, primarily concerned with the mass production of timber, to a post‐industrial regime, within which timber production sits alongside a broader range of social, economic and environmental objectives. Investigations of this transition, however, have been largely restricted to analyses of national policy discourse, with relatively little attention given to the implementation of post‐industrial forestry in regional and local spaces. In this paper, we argue that the emergence of this new forestry regime has been associated with a great deal of spatial complexity. Drawing on findings from recent research in the southern valleys of Wales, we highlight the complex geographies bound up with the implementation of national regimes of forestry in the UK, and the significant roles played by the local socio‐natural context in facilitating and resisting the implementation of new forestry regimes in particular spaces.  相似文献

The author discusses aspects of how time appears and is used by the individual and by society. In focus is what the author calls the ideological time scale as it appears in Western society. The concept of the ideological time scale implies systems of strong, ideological signals transferred through time in the human mind from one generation to another. One such signal is the age-old concept of the hero and the symbolism projected around this concept. The paper ends with an admonition to scholars to be aware of and study the kinds of messages transferred through time by this signal system. These messages carry important information about the ways in which society directs itself in the time continuum.  相似文献

Recent studies on place--mobility relationships suggest an increasing possibility that people can have multiple place attachments at varied spatial scales. Yet, our understanding of how place attachment in different spatial scales affects mobility remains limited. This study investigates home return visits by Chinese diaspora tourists from North America who have made multiple trips to China. A total of 27 in-depth interviews with repeat home return travellers were conducted. Four different types of return movements were identified: local; dispersed; local & dispersed; and second-migration locale focused. A relationship was found between the participants’ sense of place, place identity, and home return travel. The findings suggest that home return travel is more complex than previously thought. More focused sense of place and strong personal connection to ancestral homes may lead to more localized return, while a more generic sense of place (i.e. to ‘China’) and collective personal identity would result in a more dispersed travel pattern. Family migration history and strong attachment to family's first-migration destination also lead to focused return to the place. The study highlights the fact that place and place attachment are deeply personal and can evolve over time and space.  相似文献

Calcite veins at outcrop in the Mesozoic, oil‐bearing Wessex Basin, UK, have been studied using field characterization, petrography, fluid inclusions and stable isotopes to help address the extent, timing and spatial and stratigraphic variability of basin‐scale fluid flow. The absence of quartz shows that veins formed at low temperature without an influence of hydrothermal fluids. Carbon isotopes suggest that the majority of vein calcite was derived locally from the host rock but up to one quarter of the carbon in the vein calcite came from CO2 from petroleum source rocks. Veins become progressively enriched in source‐rock‐derived CO2 from the outer margin towards the middle, indicating a growing influence of external CO2. The carbon isotope data suggest large‐scale migration of substantial amounts of CO2 around the whole basin. Fluid inclusion salinity data and interpreted water‐δ18O data show that meteoric water penetrated deep into the western part of the basin after interacting with halite‐rich evaporites in the Triassic section before entering fractured Lower and Middle Jurassic rocks. This large‐scale meteoric invasion of the basin probably happened during early Cenozoic uplift. A similar approach was used to reveal that, in the eastern part of the basin close to the area that underwent most uplift, uppermost Jurassic and Cretaceous rocks underwent vein formation in the presence of marine connate water suggesting a closed system. Stratigraphically underlying Upper Jurassic mudstone and Lower Cretaceous sandstone, in the most uplifted part of the basin, contain veins that resulted from intermediate behaviour with input from saline meteoric water and marine connate waters. Thus, while source‐rock‐derived CO2 seems to have permeated the entire section, water movement has been more restricted. Oil‐filled inclusions in vein calcite have been found within dominant E‐W trending normal faults, suggesting that these may have facilitated oil migration.  相似文献

This article attempts to explore the dynamic behavior of traditional Dieh-Dou timber structure under different combinations of structural forms and vertical loads. Using time-history record (TCU 084) from the Chi-Chi earthquake, two semi full-scale specimens (Symmetric and Asymmetric) were tested. Results showed that the Symmetric specimen tends to be damaged more easily and faster than the Asymmetric one. Damage pattern generally begins from the bottom Dou members and subsequently spreading upwards to the upper Dou, horizontal Gong members, and adjoining Shu members. Friction force between the contact surfaces is crucial towards the maintenance of overall structure. Increase vertical loadings have significant effect on the natural frequencies and global stiffness of the structure. Using the Single-Degree-Of-Freedom (SDOF) system, the derived stiffness is generally in good agreement with the dynamic results of both forms. This study suggests that the effects of increasing vertical loadings should be taken into consideration for future evaluation.  相似文献

Having been launched at a symposium at Nottingham Trent University in February 2013, the themed section Queer/ing Regions addresses the potentials of critical regionalisms in contemporary queer studies. The section explores the ways in which the complex regional/local formations of sexual dissidence emerges, if not being instrumentalized, as objects of theoretical inquiry when addressed within a global context by means of transnational formations of academic practice. Rather than appropriating queer theory through a global-local vector and affirming the complex alterity of the local vis-à-vis the flattening performative of the global, the contributors underline the regional complexities of sexual politics, the multi-scalar aspects of its spatial production, and the discourses of its worlding.  相似文献

This paper examines processes of financialisation in the Arab world, a region that has been almost completely absent from the wider financial literature. The paper shows that financialisation is much more than simply the expansion of financial markets within neatly bounded sets of social relations operating at the national scale. In the Arab world, financialisation has been marked by the growing weight of regional finance capital—most specifically, those capital groups based in the Gulf Cooperation Council—in circuits of capital operating at all scales. This has important implications for processes of class and state formation. Approaching financialisation in this manner—moving away from methodologically nationalist assumptions and the literature's largely singular focus on the advanced capitalist core—brings into focus the significance of cross‐scalar accumulation patterns, their spatial hierarchies, and geographic unevenness. The paper thus reaffirms the need for a more spatially sensitive approach to financialisation.  相似文献
