Varför barn fortfarande vräks : En kvalitativ jämförande studie om socialtjänstens användande av disciplin i ärenden där barn riskerar att vräkas

Kuyumcuoglu, Jessica, Kindezi, Chrisante January 2013 (has links)
The purpose of this study was to examine whether the degree of discipline in social services may be the reason why more children are evicted in one municipality in Stockholm, compared to another. Since our purpose was to study the degree of discipline in social services work with eviction cases where children are concerned, discipline is therefore a central part of the study. The interest in the subject arose from our prior understanding that social services approach to discipline may affect the extent of evictions. In order to answer the study’s question at issue, a qualitative interview was conducted to create an understanding of the discipline and a vignette study was conducted to compare the social workers assessments in two municipalities in Stockholm, Högstad and Lågby. The study's interviews and vignette study was complemented with previous research related to the topic. The theoretical perspective was the basis for the analysis of the empirical study and consisted interconnection of theory by Michel Foucaults as well as Greta Marie Skaus and Erich Fromms perspective which helped us create a better understanding of the discipline in social services. In conclusion, we discussed thoughts and ideas that arose during the study and the results show, among other things, obvious elements of discipline in social services. Additional knowledge from the study contributed to increased understanding was in which way the social services approach to discipline affects their assessments in eviction cases where children are concerned.

FRAMTIDENS BETONG.- Blir det bättre än trä? / HE FUTURE OF CONCRETE - Will it surpass wood?

Ward, Martin, Markström, Liv January 2022 (has links)
Idag är det viktigare än någonsin att koldioxidutsläppen börjar minska. Över hela världens sätts idag visioner, mål och regleringar som ska motverka de enorma klimatutsläppen som utges varje år. Byggbranschen är en stor bov och i Sverige står dem för nästan en femtedel av utsläppen. I EU står cementtillverkningen för nästan 3 procent av alla koldioxidutsläpp.  Cementa, Sveriges största cementtillverkare, har jobbat hårt sedan 2020 med att lägga upp en plan – Nollvision 2030. Med hjälp av CCS-tekniken kommer Cementas koldioxidutsläpp inte ta sig ut i atmosfären och därför bli noll. Utsläppen kommer istället lagras och förvaras under havsbotten och därför inte bidra till klimatförändringarna negativt. Denna CCS-fabrik kommer utvecklas på Slite, Gotland, under Cementas redan befintliga cementfabrik.  I detta arbete kommer utsläppen från dagens betong och framtidens betong presenteras samt jämföras. Med hjälp av Cementa och flera andra aktörer har data samlats in som lagt grunden till en livscykelanalys (LCA). En livscykelanalys är ett verktyg som visar hur stor klimatpåverkan en produkt har under sin livstid. I detta arbete har en helt ny LCA gjorts för framtidens betong där värdena jämförs med en LCA för dagens betong. Med hjälp av denna jämförelse går det att se hur positivt Slite kommer påverka klimatmålen för framtiden. Ett tidigare examensarbete har använts för att hitta en LCA för ett betonghus och trähus. Där framkom data för ett trähus som också kommer användas vid ena frågeställningen. Där är målet att se ifall framtidens betonghus skulle kunna släppa ut mindre koldioxid än trähus, vilket det sedan framkommer att det gör. När LCA:erna var färdiga och redo att jämföras framkom det tydligt att framtidens betong har betydligt lägre utsläpp än dagens betong. Utsläppen från framtidens betong var även mindre än trähus om jämförelsen gjordes från vagga till grav. Jämförelserna har gjorts i kg koldioxidekvivalent/m2 tempererad area. / Today, it is more important than ever that carbon dioxide emissions begin to decrease. Visions, goals, and regulations are being set all over the world today to counteract the enormous climate emissions that are released every year. The construction industry is a big culprit and in Sweden, they account for almost a fifth of emissions. Of these carbon dioxide emissions, cement production accounts for almost 8%, with the worst emissions occurring during the production state. Cementa, Sweden's largest cement manufacturer, has worked hard since 2020 to set up a plan - Agenda 2030. With the help of CCS technologies, Cementa's carbon dioxide emissions will not be released into the atmosphere and therefore have zero emissions. The emissions will instead be compressed and stored under the seabed and therefore not contribute to climate change negatively. This CCS manufactory will be developed on Slite, Gotland, under Cementa's already existing cement factory.In this rapport, the emissions from today's concrete and the concrete of the future will be presented and compared. With the help of Cementa and several other contributors, data has been collected that laid the foundation for a life cycle assessment (LCA). A life cycle assessment is a tool that shows how much of a climate impact a product has during its lifetime. In this work, a completely new LCA has been made for the concrete of the future where the values have been compared with an LCA for today's concrete. With this comparison, it is possible to see how positively Slite will affect the climate goals in the future.  A previous degree project has been used to find an LCA for a concrete house and a wood house. There was data for a wooden house that will also be used for one issue. The goal here is to see if the concrete houses of the future could emit less carbon dioxide than wooden houses, which will then be proven to be true.  When the LCAs were done and ready to be compared, it became clear that the concrete of the future will have a significantly lower emission value than today's concrete. The emissions from the concrete of the future were also lower than wooden houses, if the comparison was made from cradle to grave. The comparisons have been made in kg carbon dioxide equivalent/m2 temperate area.
