The Portuguese agglomeration of Porto Litoral is one of the several European Union urban areas that had to develop and implement AQPs to reduce particulate matter (PM10). The AQPs were initially designed based on a scenario approach and using an air quality model, which was applied over the study region for the reference situation with the current PM10 emissions, and for a reduction scenario with PM10 emissions re-estimated considering the implementation of abatement measures. Aiming to cost-efficiently optimize Porto Litoral PM10 abatement measures, the assessment procedure was repeated using an optimization approach based on the RIAT + (regional integrated assessment tool +). Porto Litoral urban area's technical and non-technical measures were characterized (including associated costs) and, through the application of the air quality model to 20 emissions abatement scenarios, S-R (source-receptor) relationships were created. This paper comparatively describes the air quality plans designed to improve PM10 levels in the Porto Litoral agglomeration based on both the scenario analysis and the optimization approach.展开更多

Then they were the first large refugee group in Finland. They have got integration problems with Finnish society and from that perspective the author started to doubt that whether migrants adopted the same kinds of relationship with the local places and which kind of influence it would have on their integration. The author's aim for this study has been to explore their sense of belonging from transnational family and geographical perspectives. Relph argued that placelessness could be created either by individual itself or urban planning. With the content analyses the author analyzed 50 questions from seven respondents. The questionnaire includes the part of transnational contact keeping among kin members of transnational family, migration and respondents' sense toward urban surrounding where they lives. Emotional ties play a maior role in Finnish Somalis' diasporic life. Emotions intertwine around their life as members of transnational family and toward sense of place. Transnational family affects their perspectives toward western society and urban places. Placelessness is the first step toward integration and positive sense of place. With the integration placelessness turns to placeness.展开更多
