Pearls have been a valued resource in most cultures that had access to them. A number of historically important pearling grounds were situated in the waters around today's Indonesia. One of these areas, now largely forgotten, was the Segara Anakan lagoon in South Java. In the seventeenth century, Dutch colonists exploited the lagoon's pearls. Afterwards, the lagoon's oysters were locally exploited as a food item until the late 1970s. While the pearl fishery attracted considerable attention in the colonial literature, its disappearance, by contrast, went largely undocumented. Nowadays, the oysters no longer are found in the lagoon as a result of extensive sedimentation processes. Their former existence is only preserved in the memory of local people. This article examines the history and fate of the pearls of Segara Anakan, providing an example of a formerly valued species whose existence simply became forgotten outside the area. 相似文献

This study explores the spatial structure of retailing in Milwaukee, Wisconsin, in the era before the introduction of the electric streetcar in 1890. It uses city directory listings to chart changes in the numbers and types of retail outlets, their degree of nucleation and the functional complexity of such nucleations. The evidence suggests the early appearance of non-central retailing, the rapid dispersal of high as well as low order goods to non-central sites and the early emergence initially of a three-level and then, by 1870, a four-level hierarchy of shopping clusters. The pattern of retail clustering varied with the class and ethnic character of neighbourhoods, and clusters gravitated toward major arterial routes even in the pre-mass transit ear. Urban retailing in the second half of the nineteenth century was neither randomly dispersed nor over-whelmingly concentrated in a single central retail district, but developed a spatial hierarchy that clearly anticipated modern patterns. 相似文献

Facility location models are examined as a framework for generating rain gauge networks designed to reduce errors in mean areal precipitation (MAP) estimation. Errors in estimating MAP may be divided into two types: (i) capture error, not observing a storm which occurs in a gauged area, and (ii) extrapolation error, using a rain gauge measurement to represent a heterogeneous area. In this paper, five rain gauge location models are developed to minimize these errors. The models include adaptations of the maximal covering location problem, the p-median model, and three models derived from multicriteria cluster analysis. The models are tested using precipitation data from an experimental watershed maintained by the U.S. Department of Agriculture in Arizona. Analysis of the results reveals, for the particular watershed, that (1) in sparse networks, location of rain gauges can play a larger role than number of rain gauges in reducing errors in MAP estimates; (2) models based on mean hydrologic data provide nearly as good networks as models based on spatially correlated data; and (3) models yielding the best networks for estimating precipitation for flood predictions are different from the models providing the best precipitation estimates for low flow forecasts. 相似文献

Models of both primate and hunter-gatherer decision-making systems are developed and their relative abilities potentially to detect certain classes of spatial distributions within a standardized environment are compared. It is demonstrated that in situations where language facilitates the pooling of information between individuals within a hunter-gatherer group, the group minimally need only to pool information with one central decision maker in order potentially to recognize all possible spatial distributions within a limited environment. On this basis alone, we would theoretically expect the presence of one-leader groups to be a fairly ubiquitous phenomenon among hunter-gatherers. 相似文献

In the post-imperial world of sixth-century Gaul, the Church found itself competing for allegiance with strengthened local family groupings as well as royal households. In this milieu the fragmentation of power and the propensity for spoliation of church lands posed a severe problem for ecclesiastical survival. An answer might be found in a competing kindred structure: the family of the saint. Such an entity would have the benefit of building a support group for the Church that could cut across the existing family lines and thereby weaken their impact. As a voluntary association based on the celestial it would have the added benefit of being a familia everlasting, and endlessly elastic.The works of Gregory of Tours contain such an idea built around his patronus, St Martin. Gregory's preface to Book 5 of his History, and his frequent pleas against feuding, show his concern as to how the familia Sancti Martini could perform an annealing function for society, mitigate the more rebarbative elements of the feud, and leave the Church in a strengthened position in society. 相似文献

Critics have been uncertain as to the genre of Catalan writer Jaume Cabré's 2000 book, Viatge d’hivern. The confusion, I argue, is due to the fact that the volume is a short story cycle, a literary form situated midway between the novel and the short story collection. Forrest Ingram differentiates among composed, arranged, and completed cycles, and Cabré's comments in his Epilogue to Viatge d’hivern indicate that the book is an example of the third category. While he composed its fourteen narratives over a period of years, when he revised them for inclusion in a single volume he discovered that various threads, some secret and others more obvious, connected the stories. In this essay I examine ways in which theme, structure, and motifs, as well as recurrent imagery and wording, form a web of associations among the individual units of Viatge d’hivern. 相似文献

ABSTRACTCities are growing rapidly, and the systems of production and consumption that support this growth are contributing to the depletion of natural resources and pollution of the environment. The circular economy model offers an alternative to the predominant take-make-dispose economic system. Local municipalities are seen to have the capacity to encourage sustainable development of the built environment. This paper aims to explore the role of strategic planning in facilitating a circular economy in urban settings. In particular, this research asks: How are local governments facilitating circular economy initiatives through strategic planning? What are the opportunities and barriers when applying circular economy principles through local strategic planning? The research approach used for this paper is a comparative case study of two international municipalities: the City of Melbourne, Australia and the City of Malmö, Sweden. Current strategic planning practice was examined with a focus on circular economy themes. The findings reveal that strategic urban planning can translate circular economy objectives into actions within specific urban areas, although barriers still exist to fully integrating the circular economy model. 相似文献
