The long-standing correlation between community function and nucleated settlement form in early colonial New England is mistaken. Puritan communities were established, but new communities—often called villages in colonial records—were developed and survived quite well regardless of settlement form. As in England at the time, village meant community and community was a social web. Village status in New England provided a community with land and thus enabled the community to undertake settlement. But the social web that comprised community did not require nucleated settlement, and the dispersed settlement form that many colonists had known in England dominated the village landscape of early colonial New England. 相似文献

City dwellers occasionally must seek jobs, dwellings, or particular services or goods. Two very different ways exist by which the individual may conduct such a search. Lacking prior information, the person may elect to visit perceived possible locations until an appropriate one is found. Alternatively, an address may first be ascertained and then visited by finding a path to it. Clearly, there is a substantial difference between these two methods in terms of the amount of spatial movement they require in order to satisfy the searcher's needs. In this paper, this difference is modeled for situations that vary in terms of the density of acceptable end points of the search, as well as in characteristics of the signs of these end points, their patterns, and the level of information with which the searcher may begin. 相似文献
