Fröåtjärns föroreningshistoria : Utredning av hur metallbelastningen varierat över tid med hjälp av sediment som ett naturligt historiearkiv
The metal mining history goes thousands of years back. The downside of the mining industry is the large amount of tailings created during the mining operations. Drainage and leaching of heavy metals from these tailings may cause major environmental problems including acid mine drainage and leaching of heavy metals. This study examines a pond located near an old mining site, where part of the old mining facility has been recently (1990) restored. The objective was to assess eventual metal contamination from historical mining and the recently performed restoration using a sediment core as a natural archive of historical metal inputs to the pond.
Kommunalt naturskydd som en del av markanvändningsplaneringen : en fallstudie av olika synsätt i samband med upphävande av naturreservat
In metropolitan areas where the exploitation pressure increases, also the importance to point out nature areas grows, both for the sake of outdoor life and for biodiversity conservation. Since nature conservancy and spatial planning constitute two different parts of the municipalities land use control, a case study has been carried out in two municipalities in the Stockholm region, Huddinge and Järfälla. Both these municipalities have protected about one third of their land and today there are plans to repeal parts of the reserves to enable exploitation. This thesis shows ? from the theoretical concept of sustainable development ? officials, politicians and non-governmental organizations perspectives on questions concerning land use together with the work with nature reserves and repeals.

Anonymitetens implementeringsproblem - En studie om Kortedalas försök av avidentifierade jobbansökningar
Anonymous job applications as a method to further diversity on the labour market is widely discussed. The method aims to promote an equal selection procedure, where the employer can only judge on merits and experience. We are with this study on the other hand interested in seeing how this specific method of employment has been implemented. We have chosen to perform a small qualitative case study, of a limited attempt of this method in the government administration of Kortedala, a district in Gothenburg.Our intrests are to see whether we can, while studying a specific implementation procedure, show that any implementation problems have occurred. Furthermore explaining it by applying our implementation theory, that consists of Lennart Lundquists three criterias for explaining implementation problems experienced from the appliers' standpoint.

Ur askan i elden? : Om psykologiskt arbete med asylsökande barn
This phenomenological study explores the mental health problems of asylum- seeking children in Sweden and highlights possible ways of meeting their needs. Open interviews with 13 clinically experienced psychologists were conducted.The results of the analysis suggest that experiences of trauma and separation, the child's developmental level, parental functioning and family dynamics contribute to the mental health problems of asylum- seeking children. When meeting these children the psychologists continuously face ethical dilemmas since the asylum-seeking process seems to aggravate the problems as well as complicate the use of traditional interventions. Promoting structure and activity, normalizing symptoms, educating about trauma and crisis, sharing and accepting anxieties and sometimes thoroughly working through traumatic experiences are treatment strategies found clinically useful. Systematic follow-up studies are needed to decide the effects of these interventions..
Effektiviseringspotential inom industrisektorn : Energibesparing vid frekvensstyrning av centrifugalpumpar ? en fallstudie
The project was performed at SiemensIndustry Drive Technologies with theobjective to provide actual values forthe energy savings potential withinSiemens scope of practice.In Sweden the electrical drives standfor about 30 % of the total electricityconsumption and about 60 % of theelectricity consumption within theindustry. During the pre-study phaseelectrical drives with pump applicationswere identified as large energy users.Because of this a case study at one ofSiemens customers, Stora Enso Fors wasperformed. The system that was evaluatedduring the case study was a throttledsystem with a centrifugal pump forpumping pulp.The results yielded that a saving ofover 50 % could be achieved by replacingthe throttle valve with a variable speeddrive, a frequency converter. Thepayback period was two years and twomonths and the present value for thetotal life cycle cost of the variablespeed system was 662.566 SEK lower thanfor the throttled system. As aconsequence, Stora Enso Fors is advisedto invest in a frequency converter forregulation of the system.The general conclusion is that a focuson system efficiency is the mostimportant factor in energy efficiencyprojects and that the system regulationmethod has a large impact on the overallsystem losses and hence its efficiency.Energy efficiency potential forthrottled systems with centrifugal pumpsis large and significant economicalsavings can be made through investmentswith short payback time..
En studie om hur ADHD/DAMP skildras i fem barnlitterära verk
The purpose of this study is to find out, explore and see how children with neuropsychiatric problems like ADHD/DAMP are portrayed and treated in five fictional children?s books written by writers who all are related to ADHD issues, except for one writer.I have done a text analysis performed on five children?s books which can be found in libraries in most of the libraries in Sweden. The analysis shows varying results between the five books followed by a general conclusion about how children with concentration problems are being presented in these chosen children's literature. The main problematic of this study is to examine how these characters are being represented and treated within the scopes of school, family relations and how ADHD/DAMP symptoms are portrayed. This study focuses on analysing how the actual ADHD/DAMP behaviour is being reflected and better understanding for the reader to understand the symptoms of ADHD.Another fact is what kind of relations these children with neuropsychiatric dysfunctions are portrayed when facing with other persons, such as family and friends and how ADHD/DAMP is affecting them daily basis.
Barn i terapiskola : en mixad studie om föräldrars upplevelse av sitt barns utveckling på terapiskolan Liljanskolan
This study is an evaluation of the school Liljanskolan, which is a ?therapy-school? for children between the ages of seven and twelve with psychosocial problems. These problems can concern difficulties interacting with adults as well as children, acting out, difficulty concentrating and anxiety. Liljanskolan has a high number of professionals, both teachers and treaters, and few children. The aim of the study was to increase the understanding of how children that have attended Liljanskolan have progressed during their time at the school with focus on their behaviour in school, ability to interact with adults and children, anger management and self-confidence.

Lantbrukare och rådgivare : tillsammans kan de främja biologisk mångfald.
With the farming methods of the past century the agricultural landscape has changed. This has led to the fact that many habitats and species have been significantly reduced. Sweden is committed to the preservation of biodiversity through various conventions and laws. In the EU's Common Agricultural Policy there are currently agro-environmental schemes, which were created as an instrument for reducing the negative impacts of agriculture on nature and environment. Within this system any farmer who perform environmental measures are financially compensated for this.
Referensvåtmarker för uppföljning av växtnäringsretention i anlagda våtmarker
One of the environmental problems today in seas, lakes and streams is eutrophication. This is often caused by nutrients such as phosphorus (P) and nitrogen (N) that leak from agricultural areas. A measure to partly prevent the nutrient discharge is to construct or restore wetlands.In order to control the efficiency of nutrient reduction of existing wetlands in the county, the administrative board in Västra Götaland wants to find different criterias for reference wetlands. These reference wetlands should represent other wetlands and be used in future evaluations of reduction of nutrients and design of constructed wetlands. According to the administrative board in Västra Götaland the reference wetlands should have a catchment area of about 50 hectare consisting of at least 70 % arable land, to represent wetlands created to remove nutrients.
Miljöpolitik eller personlig frihet? : fallstudie av Växjö Kommun
This thesis is a case-study of an ongoing court case between the Swedish Competition Agency and Växjö Municipality about a set-up requirement to the long-distance heating system for newly built private houses on municipality owned land. This requirement was set up as part of the municipality?s long-term environmental goals; however the Competition Agency claims that the demand is damaging the free market in the municipality. The purpose of this thesis is to determine which normative assumptions the decision makers have based their actions and re-action on, and whether or not these assumptions are valid, thru theoretical ideal types. This is determined via method of textual analysis.
