An Assessment of the Networks for Measuring and Modelling Solar Radiation in British Columbia and Adjacent Areas of Western Canada

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.
Les auteurs presentent une evaluation de la distribution des stations en Colombie britannique et les aires adjacents du Canada de I'ouest mesurant la radiation solaire; ils en concluent que le reseau actuel est inadequat. 11s soulignent I'avantage d'emprunter un modele numerique pour caracteriser la radiation solaire aux sites disponibles, afin d'aug-menter les donnees observees. 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.     

Contested multi‐level governance: Merseyside and the European structural funds

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.     

Archaeological Amerindian and Eskimo cranioskeletal size variation along coastal western North America: relation to climate,the reconstructed diet high in marine animal foods,and demographic stress

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.     

The preservationist paradox: modernism, environmentalism and the politics of spatial division

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.
