Results of the 2007/08 survey "Energy--the present and the future" conducted on a population of 1439 students from Zagreb University have shown that after school and television, internet is the third major source of knowledge for the participants. Therefore, "NEMIS" web site (www.nemis.zpf.fer.hr) was launched at the end of the 2008. NEMIS is a Croatian acronym for "Nuclear Energy--Mysticism and Reality". The site was envisioned as a place where interested visitors could get information, prepared by experts, on all the issues relating to nuclear energy. The main objectives of the work reported in this paper are to present the structure of the NEMIS web site and to analyze the activity on the site during the last three years. Based on the performed analysis, future activities on the site are set and discussed. 展开更多

This paper will present a television program based on glocal (global + local) culture and sustainability concepts, such as local production, social support and cultural diversity, done with virtual and social networks. The result is NosOtros1. Its name is a play of words between Nos-we in Portuguese and Otros--other in Spanish. The purpose is to practice a journalistic and cultural production process which would understand local specificities and global themes. NosOtros used professional networks in journalism to compose a cultural, democratic, and balanced program, understood and accepted across all of Latin America. NrsOtros was recorded in four countries in 2007, co-produced by local journalists, using professional networks and new media technologies such as Voice over Internet Protocol (VolP) and peer-to-peer programs. 展开更多

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. 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
