The expansion of the European Union in the 21th century will bring with it new tasks in education. Among the predominant ones are issues related to commonalities and diversities found within each nation's own education system. Until now the European states have focused on diversities found within their own national education systems. The ongoing integration process in Europe will mean transnational perspectives need more attention. Processes of globalisation, economic integration, social mobility, migration and political integration will persist into the next century and produce new forms of commonalities, inside and outside nation states. The relationship of these processes of commonalities and diversities is a major problem and challenge for all education systems . . This volume deals with isssues related to this development in seven fields: history and theory of education, ethnicity, teacher education, youth care and special educational needs, media based education, woman and gender studies, higher education. The 43 articles are written by more than 50 authors from 15 European countries. (DIPF/Orig.)

Most HIV‐infected parents in Stockholm are of African origin. Many of them have several children, but their social network is often limited. This article looks at the networks of these families in relation to different aspects of HIV in order to improve the support strategies. The theoretical basis of the study rests on network and ecological systems theory. The social networks of the families in the study were found to be generally of similar size in Sweden and in the home country. However, of 47 HIV‐infected parents only 21 (45%) had disclosed their HIV status to friends and relatives in Sweden. The lack of a social network was especially prominent among single women. Contact with counsellors at the HIV clinic and the social welfare office increased the probability of disclosure about HIV infection. The lack of knowledge about HIV transmission and about whom to inform about the infection stresses the importance of improved counselling. The support strategies aimed at broadening the patient's network and breaking their isolation need to be continued and strengthened.

The present text compiles the latest research within the field of biology performed in the Baltic Sea area. The themes span from theoretical and philosophical aspects of the ecosystem concept over population and autecological studies to detailed descriptions of plant and animal physiology. Results from microcosm and mesocosm experiments as well as direct observations in field together bring insight of the special structure and function of the Baltic Sea ecosystem. How the spawning success of cod and spat are dependent of each other and environmental factors, the impact of alien species to the composition of plankton or benthic communities, the flip of phytobenthic to planktonic communities in lagoons and mechanisms triggering the change, pure descriptions of e.g. the Estonian coast and shallow off shore areas as well as strategies for the reproductive success of Fucus vesiculosus, and the influence of eutrophication of the different Baltic Sea areas and the fate of pollutants as radionucleids and PAH etc. and other themes are all discussed in the 24 original papers of this volume

The public sector makes long-term investments in for example tram rail lines and highways based on forecasts of future travelling but generally do not consider the impacts of self-driving technology as a factor. Several papers have presented transport system wide simulations with self-driving cars, exploring changes in mode choice, energy demand or the potential for sharing. Demand traffic models have been used in several studies, looking at modal choice changes, but the general assumption is that the public transport service remains unchanged, despite a large potential for governments to enhance service or reduce costs. This paper examines the effects of self-driving technology on the transport system with Stockholm, Sweden as a case study, looking at four scenarios which were developed with input from 130 transport professionals from industry, academia and the public sector. Each of the scenarios include one "car" and one "public transport" mode, looking at changes in e.g. modal choice and person kilometers traveled. The national demand model Sampers is used for evaluation. The results indicate a decrease in walking and bicycling in all scenarios and a decrease in public transport travelling in scenarios with a taxi-like car service. Although this result would mean a shift from public transport to car travel, the majority of travel to and from central parts of Stockholm were still made by public transport. ; QC 20201005 ; Självkörande fordon och kollektivtrafik - Hot och möjligheter
