O.F.G. SITWELL 《The Canadian geographer》1993,37(4):332-351
The special number of the Canadian Geographer devoted to West Edmonton Mall raises important questions, notably that of the relative status, as values, of work (seen historically as fundamental to our culture), and of leisure, perceived, albeit controversially, as being embodied in wem. In preparing to present my principal thesis, I review recent reinterpretations of human behaviour advanced by workers in the fields of symbolic interaction and the sociology of knowledge. These schools ha ve given rise to the concept of, though not the term, functional religion. The meaning of this concept is close to that of ideology; a comparative analysis of the two terms justifies using the former. A survey of recent work by geographers who approach religion from a functional point of view closes the second part of the paper. In the course of this review the relative status of work and leisure emerges as a significant issue. The view of leisure as a norm presented in the third part of the paper is that advocated by Pieper, Huizinga, and de Grazia. They argue that the Classical view, according to which human life finds its meaning in activities that are carried on for their own sake (e.g., games), rather than in those pursued for the material rewards they offer, is correct. Following their lead, and in opposition to both Marxists and Liberals, I argue that the adoption of leisure as a fundamental value would provide a more satisfactory foundation for our culture than work has to this point. Le numéro spécial du Géographe canadien consacréà?étude du West Edmonton Mall soulève plusieurs questions importantes, notamment celle du statut relatif, comme valeur, du travail (valeur-clé historiquement dans notre culture) et du loisir, valeurs incarnées, bien que de façon controversées, dans le WEM. Pour établir les bases de la thèse principale, on examine les réinterprétations récentes du comportement hurnain avancées, dans les sciences humaines, par des chercheurs travaillant dans les domaines de ?interaction symbolique et la sociologie du savoir. Ces écoles ont engendré le concept, sinon le terme, de la religion fonctionelle. Le sens de ce terme est proche de celui de ?idéologie; une analyse comparative des deux termes justifie ?emploi du premier. Pour conclure la deuxièrne partie de ce mémoire, on passe en revue quelques écrits récents par des géographes qui abordent la religion ?un point de vue fonctionnel. De cet examen il ressort que le statut relative du travail et du loisir est ?une importance capitale. Dans la troisième partie, on présente une perspective sur le loisir qui est proche de celle qu'avancent Pieper, Huizinga, et de Grazia. Ceux-cisupportent la position des auteurs classiques, selon qui la vie humaine trouve sa signification dans les activités entreprises pour ellesměmes (par exemple, les jeux) plutǒt que pour le gain matériel. Appuyant leur argument, et m'opposant à celui des marxistes et des libéraux, je prétends que ?adoption du loisir comme vaieur fondamentale fournirait une meilleure assise à notre culture que celle offerte jusqu'ici par le travail. 相似文献

Revegetated Sand Mining Areas,Swamp Wallabies and Remote Sensing: North Stradbroke Island,Queensland
Mining of mineral sands has taken place on North Stradbroke Island for over 40 years. Revegetation of mined areas creates a mosaic of seral classes. For a mine site in the northwest of the island, Landsat Thematic Mapper data were used successfully to map the distribution of seven seral classes resulting from mining rehabilitation. Faecal pellet counts were used to assess usage of these areas and surrounding natural forest by swamp wallabies, Wallabia bicolor. Results indicated that revegetated sites from 2 to 4 years in age were heavily used by wallabies. Older revegetated sites, dominated by senile Acacia cunninghamii, and offering little or no forage, were avoided. Swamp wallabies used revegetated sites for night-time feeding sessions and rested, during the day, in surrounding eucalypt forest. 相似文献

The article seeks to enhance understanding of post-transitional demographic change by examining the working out at the local level of the macro-scale societal processes underpinning the recent cyclic oscillation in Australian reproductive behaviour. Variations in urban marital and overall fertility between 1966 and 1971 and between 1971 and 1976 are described and analysed. In general, inter-urban variability in both measures diminished greatly, as did the explanatory power of ecological differentials, suggesting widespread acceptance of the small family norm throughout the study-area. While the process of convergence was continuous for marital fertility, structural changes contributed to later divergence of overall fertility levels, in accordance with Alonso's cyclical model of change. The current low level of residual inter-urban variability suggests that little more may be gained from analyses of this type. 相似文献

Archaeologists, along with other Quaternary researchers, seldom rely upon a single radiocarbon determination to provide an estimate of the age of the phenomenon which is the object of their study. There is an evident need for an explicitly formulated procedure for comparing sets of radiocarbon determinations from the same and from adjacent strata or sites, and for combining these where statistical and archaeological criteria indicate that this combination is warranted. The present contribution provides explicit modelling for a series of recommended procedures, a critique of previous methods, and paradigms for application of the recommended procedures. 相似文献

Among the manifestations of radioactive decay which can be etched to optical visibility on the surface of mica are tracks from nuclei recoiling from alpha emission, called ‘alpha-recoil tracks’. If, beforeetching, the mica is heated to temperatures of the order of 600°C, all evidence of these tracks is annealed from muscovite mica in a few minutes. Alpha activity observed on mica from pot sherds, from stones surrounding fire places, from fire pits, and fired daub may constitute an alpha-recoil track clock which started at the moment of the last firing of the artifacts. 相似文献
