The Young Geographers, an informal organization of American geographers, flourished from 1936 to 1943. One of its projects in 1940 and 1941 was the compilation and publication of lists of contemplated research by some 170 Young Geographers. Their listed research interests were relatively narrow in subject and geographical area. The successor of the Young Geographers was the American Society for Professional Geographers which merged with the Association of American Geographers in 1948 under a democratic constitution which assured that young geographers and their research would be recognized.  相似文献

The discussion of agricultural restructuring has often failed to include farm women, particularly those who own and operate their own enterprises. Accordingly, this research presents an overview of Canadian female farm operators, who are a growing component of the farm operator population. Using previously untabulated data from the 1971, 1981, and 1986 censuses of agriculture and population, the study draws comparisons to male farmers in Canada and female farmers in the United States. The census data show that the socioeconomic and farming profile of Canadian female farmers differs from that of their male colleagues, and that the differences in certain key characteristics (such as farm size, sales, and commodity type) are becoming more noticeable over time. This raises questions about whether female operators are in danger of becoming marginalized from mainstream production, and whether their needs as a minority group among agricultural producers are being recognized.  相似文献

ABSTRACT. The segregation of Catholics and Protestants varies spatially and temporally in Belfast, Northern Ireland. Using small-area statistics from the censuses of 1971, 1981, and 1991, taken during the recent “Troubles,” a strongly rising level of ethnic segregation is noted for the 1970s, followed by a more gentle rise in the 1980s. Segregation is shown to vary among subunits of the urban area. The basic cause of this segregation is ethnic violence, and the spatial variation in segregation can be attributed to spatial variation in this violence.  相似文献

In spite of the considerable economic importance of high order (intermediate demand) services, research on the growth and location of these activities has remained at a fairly aggregate level. The behavior of the individual elements of this group has rarely been documented in detail. In this paper, we seek to determine if individual high order service activities are becoming spatially more concentrated or dispersed across the Canadian urban system, and to determine if differential rates of growth may be observed by region and by urban size category. These issues are of considerable importance in the ongoing debate concerning the impact of the tertiarization of the economy on uneven spatial development. We examine the performance and location of 17 individual high order service activities over a set of 152 Canadian urban areas with populations greater than 10,000 inhabitants. Most of these activities are highly concentrated in a small number of very large urban areas, and their level of concentration declined only very slightly over the period 1971–1991. We conclude with an examination of the factors underlying the geographic concentration of high order services at the upper end of the urban hierarchy.  相似文献
