The coverage provided by the existing solar radiation monitoring network for British Columbia and adjacent areas in western Canada is assessed and found to be inadequate. It is generally advantageous to use a numerical solar radiation model at available sites to augment the observed values, although this is not a complete solution to the problem. It is also shown that the ability to extrapolate solar radiation data from measurement and modelling locations is strongly determined by the general nature of the synoptic weather conditions. In addition, the use of solar radiation extrapolations is restricted by problems involving homogeneity and isotropy assumptions.

Neanmoins, cela ne represente pas pour les auteurs une solution complete du probleme. 11s demontrent que le caractere general des conditions meteorologiques synoptiques determine fortement la possibilite d'une extrapolation de la distribution de la radiation solaire, derivee des donnees mesurees et des modeles adoptes aux sites specifiques. Finalement, ils etablissent que certains problemes concernant les hypo-theses d'homogeneite et d'isotropie imposent leur tour des limites a I'utilite de la methoded'extrapolation pour decrire la radiation solaire. 相似文献

This paper critically explores the problems and tensions that occur within a multi‐level governance structure. It examines the (conflictual) relationships between the European Commission (EC), the UK Government, and regional and local actors. The case study is Merseyside's European Union Objective I Programme, with particular reference to the Pathways to Integration initiative in the Borough of Knowsley. It traces the design of policy and its delivery and argues that these processes are riven by acutely contested power relations. Objective 1 generally, and Pathways specifically, provided a substantial opportunity for Merseyside, but conflicts over economic governance act as a debilitating force upon the prospects for economic development. 相似文献

A quantitative bioenvironmental study of cranioskeletal size has been made of a latitude-ordered sequence of 14 series of adult skeleton sets (N=305): the archaeological remains of aboriginal maritime peoples inhabiting the west coast of North America between southern California and the Arctic. Of eight osteometric parameters of cranioskeletal size developed, the most important are partial skeleton volume (PSK) and cranial capacity (CC); and the principal bone-affecting environmental factors are the northerly climate (CLIM2c), the reconstructed diet deficient in calcium and overabundant in animal foods and vitamin D (DIET3c), and demographic stress (DSg). Prior research has demonstrated that cranioskeletal size increases with geographical latitude and decreases under dietary calcioprivation and unphysiologically high birth rates. Upon linear multifactorial statistical analysis our main finding, limited to the Amerindian subsequence (n=11 series) from the Santa Barbara Channel, the San Francisco Bay Region and the Northwest Coast, is that PSK and CC vary in direct proportion to CLIM2c, and inversely with DIET3c and DSg. Controlling for the latter two osteoantitrophic factors, coastal Amerindian female PSK rises by 9% between 34 and 54°N latitude, CC by 5%; and the male incremental rates are somewhat higher, 13 and 10%, respectively. This newly discovered climate-dependent race cline, an example of Bergmann's Rule, is interpreted as factual evidence of a mid-Wisconsin or earlier arrival date for the first Palaeoindians. Cranioskeletal size of the very small (n=3 series) Western Eskimo subsequence approximates the northernmost values of the coastal Amerindian distribution. © 1998 John Wiley & Sons, Ltd. 相似文献

According to Bruno Latour, the imposition of crude classificatory schemes onto complex entities has two main effects: firstly, the classifications lead social actors to sift the world into the schemes' simple categories; secondly, underlying relations subvert the schemes' functioning, resulting in the production of transgressive 'hybrids'. Thus, classification and relation interact and this interaction shapes both the practice of classification and the world that is classified. In this paper, we examine the interaction between a scheme of spatial classification and the spaces that are enrolled within the scheme. We show that a division between urban and rural areas was put in place in post-war England in order to protect a 'vulnerable' rural nature from urban advance. However, as soon as it was imposed, this division was transgressed by complex socio-economic processes. We assess the response to this transgression by considering the activities of the Council for the Protection of Rural England (CPRE), an environmental group that played some considerable part in constructing the urban–rural divide in the first place. We show that the CPRE has responded to the 'paradox of preservationism' by placing urban–rural divisions in the context of 'ecological' relationships. We illustrate this 'ecologization' of the modernist divide using the example of housing and we argue that the CPRE's ecological approach illustrates how a new alignment between 'urban' and 'rural' may herald a new and more sophisticated form of spatial classification. 相似文献

In this ‘postcolonial’ era, peoples and places around the globe continue to face ongoing colonisation. Indigenous peoples in particular experience colonisation in numerous forms. Despite recent attempts to ‘decolonise’ indigenous spaces, hegemonic systems of production, governance and thinking often perpetuate colonial structures and relationships, resulting in further entrenched colonisation or ‘deep colonising’ (Rose, 1999). The interface between indigenous communities and the mining industry provides fertile ground for the tensions emerging between decolonising and deep colonising. Gold mining operations at Placer Dome's Granny Smith mine in the Eastern Goldfields of Western Australia present a valuable case study for examining this tension. Changes taking place at the mine site are decolonising in intent, though outcomes may be deep colonising in effect. Recent discussions among cultural geographers over meanings of place, Ollman's (1993) notion of vantage point and a broadly postcolonial literature inform consideration of this tension. Acknowledgment and incorporation of multiple vantage points into new resource management systems allows current hegemonic approaches to be rethought, and provides insights for the shift towards genuinely decolonising processes. 相似文献

From sustainable development to carbon control: eco-state restructuring and the politics of urban and regional development 总被引:2,自引:0,他引:2

The management of carbon emissions holds some prospect for challenging sustainable development as the organising principle of socio-environmental regulation. This paper explores the rise of a distinctive low-carbon polity as an ideological state project, and examines its potential ramifications for the regulation of economy–environment relations at the urban and regional scale. Carbon control would seem to introduce a new set of values into state regulation and this might open up possibilities for challenging mainstream modes of urban and regional development in a manner not possible under sustainable development. But low-carbon restructuring also portends intensified uneven development, new forms of state control and a socially uneven reworking of state–society relations. In order to explore these issues we start by setting out a framework for conceptualising environmental regulation based around the idea of eco-state restructuring. This idea is introduced to capture the conflicts, power struggles and strategic selectivities involved as governments seek to reconcile environmental protection with multiple other pressures and demands. Overall the paper seeks to make a distinctive contribution to theoretical work on state environmental regulation and the emerging spatial dimensions of climate policy. 相似文献

SONIC GEOGRAPHY, PLACE AND RACE IN THE FORMATION OF LOCAL IDENTITY: LIVERPOOL AND SCOUSERS 总被引:1,自引:0,他引:1
by Philip Boland 《Geografiska annaler. Series B, Human geography》2010,92(1):1-22
The concept of identity has attracted significant academic attention. This article unpacks what constitutes the Scouse identity, how it is constructed and its different dimensions, with particular reference to place, phonology and race . Its novelty lies in developing the underused concept of "sonic geography" to examine the extent to which sound, for example a distinctive accent and/or dialect, affects the construction of local identity. Empirically this is conducted through a detailed analysis of the Scouse, or Liverpudlian, identity. The article also deploys the concept of "sonic exclusion" to examine the role a distinguishing vernacular plays in shaping local identity and the extent to which it determines "who is in" and "who is out" as a Scouser. The conclusion is that an effective understanding of a Scouser is not only spatial – someone born in Liverpool – because the sonoric landscape of spoken Scouse, and thereby Scouse identity, extends beyond the contemporary political and geographic boundaries of the City of Liverpool. 相似文献
