Denna uppsats söker förstå beslutsprocessen som resulterade i att Lunds och Frederiksbergs kommun fattade beslutet om att samarbeta. Beslutsprocessen resulterade i ett informellt samarbete, och söks förstås med hjälp av Cohen, March och Olsens Garbage Can-modell, och Kingdons window of opportuntity (möjlighetsfönster). Garbage Can-modellen består av fyra flöden, som innehåller beslutstillfällen, problem, lösningar och deltagare. Dessa flöden kan kopplas samman då möjlighetsfönster uppstår, vilket sker vid opinions- eller känsloförändringar bland befolkning och politiker.Vi har kommit fram till att beslutsprocessen bör förstås som att lösningen informellt samarbete mellan Lund och Frederiksberg, kopplades till problem relaterade till att vilja vara en del av Öresundsregionen, och beslutstillfällen såsom Öresundskommittén. Deltagare drev lösningarna och identifierade problemen.

The study was based on qualitative interviews with ten professional social workers from different municipalities in Skåne in an attempt to answer the following questions:* What routines exist for the follow-up work with foster care?* What factors have an impact on how the follow-up is formed in the particular case?* How can the follow-up affect outcomes of the placement?* In what way could the work with follow-up foster home placements develop?The theories we chose to analyze our material from was the ecology of human development formed by Urie Bronfenbrenner and the theory of civil courage formed by Lennart Lundquist. The interviews were semi-structural which gave the respondents a chance to talk in a free way about the questions we presented.The result of the study showed that there is a difference in the way social workers form the follow-up work of foster care. The greatest difference is in whom the social workers include in their follow-up.

Not only developing countries are affected, even in the western world epidemics are breaking out by partake or bathing in dirty/polluted water.MIP, Molecularly Imprinted Polymers, is a biosensor technology that can provide faster and more reliable response than the current methods of water analysis. It is also cheaper and due to that more samples can be taken and analyzed.
