The cross-sectional nature of much social data, coupled with the static view provided by maps and current spatial data handling software, have produced a tradition of research on urban spatial structure that is largely two-dimensional and derived from residential locations. The paper presents an analysis of a space-time diary data set collected in Halifax, Nova Scotia. A series of transformations are used to convert the individual diary records to a three-mode matrix of intensities, which is then analyzed using the PARAFAC three-mode factor model. Home/work is found to be the strongest organizing dimension of the urban space-time, followed by entertainment, shopping, and education / work. We show how these dimensions appear to varying degrees in different locations, time periods, and human activities. The paper argues for a dynamic view of urban spatial structure in which only the physical facilities remain static. 相似文献

Although corporate groups have featured in the anthropological literature for a century, and have more recently been proposed as a potentially useful unit for archaeological analysis (L. Freeman, 1968, In Man the hunter, edited by R. Lee and I. De Vore, pp. 262–267. Aldine, Chicago), application of the concept in archaeology has largely remained hypothetical, and little theoretical modeling has been attempted. In spite of this neglect, it is argued here that the corporate group is potentially one of the most useful and important aspects of the archaeological record that can be dealt with. This conclusion is derived from a detailed ethnoar-chaeological analysis of over 150 households in the Maya Highlands, in which it became apparent that social, economic, and demographic characteristics of households were only loosely associated with a wide variety of material culture expressions. In contrast, such inferences seemed to be much more reliable when households were grouped into “hypothetical corporate groups” and group averages were compared. In addition, theoretical considerations based on economics and on interactions also indicate that the analysis of corporate groups shold be more rewarding and potentially more accurate than the analysis of individual households. Archaeologically, corporate groups can be defined where residential coherency and internal hierarchies are demonstrable. Because corporate groups can be viewed as signaling major changes in the structuring of society, and in the evolution of social and political complexity, the investigation of conditions under which corporate groups emerge should be of major theoretical significance to the entire discipline of archaeology. Moreover, because of the close logical links to material culture and the environment, theoretical modeling should be particularly amenable to archaeological testing. In sum, corporate groups provide an unusually fertile problem area which archaeologists can hope to attack with at least a promising degree of success. 相似文献

Indigenous families are overrepresented among those within Canada who experience food insecurity. Studies have largely focused on northern populations, with less attention paid to southern and urban communities, including the social, cultural, and geographic processes that challenge food security. In this study, we present findings from a decade‐long community‐based study with the Southwest Ontario Aboriginal Health Access Centre (London, Ontario) to examine family perspectives related to the social determinants of food security. These topics were explored through qualitative interviews (n = 25) and focus groups (n = 2) with First Nation mothers with young children from the city of London, and a nearby reserve community. Interviewees from both geographies identified a number of socio‐economic challenges including household income and transportation. However, some interviewees also shed light on barriers to healthy eating unique to these Indigenous contexts including access issues such as a lack of grocery stores on‐reserve; loss of knowledge related to the utilization of traditional foods; and the erosion of community, familial, and social supports. Resolving these unique determinants of food security for urban and reserve‐based First Nation families will require a range of economic and culturally specific interventions, particularly those that support development and uptake of Indigenous foodways. 相似文献
