Most geo-spatial studies regarding inter-ethnic relations are single dimensional, focusing on residential segregation assuming its association to the social domain. We argue that in the globalizing world daily activity spaces, social networks and influences on everyday life conditions are rooted in growing horizons around residential location weakening the power of residential location to dictate life conditions. Hence we suggest employing a multi-dimensional approach. Specifically, we explore the associations among residential spaces （relating to Arab residents of： purely Arab localities; mixed-Jewish-Arab cities, and Jewish cities）; main activity spaces （commuters to Jewish areas and localists--people staying mostly in the Arab localities） and social integration （social networks; repertoire of identities; attitudes toward integration and knowledge of Hebrew）. The data incorporate tracking the movements of 177 responders for a week （using a GPS logger） and in-depth interviews, which were analyzed quantitatively. Core findings suggest that both residential place and activity spaces affect social integration, however, the locality type has a greater affect. In addition, we identified four integration sorts according to kinds of municipality, activity spaces, and integration measures： （1） segregated localists living in Arab municipalities; （2） commuters living in Arab localities characterized by limited integration; （3） Arabs residing in Jewish cities that succeeded economically but are characterized by limited social integration, and （4） those living in mixed cities which enjoy the highest, yet limited integration level.展开更多

Results indicate good agreement between measured and predicted GSR values for each of the 35 locations with known GSR values. Finally, the data from all available stations are used to train an abductive network to estimate the GSR values anywhere in the Kingdom based on latitude and longitude. GSR values are estimated using the developed method at 25 additional locations throughout the kingdom and used with the measured data from the 35 available measurement stations to draw a comprehensive contour map of GSR values for KSA.展开更多

文摘This article examines integration vs. segregation of Arabs in Israel＇s social sphere. Most geo-spatial studies regarding inter-ethnic relations are single dimensional, focusing on residential segregation assuming its association to the social domain.
