Gallringsprioritering av contortabestånd :
Extensive planting of the tree species lodgepole pine (Pinus contorta var. latifolia) during the 1970s and 80s has resulted in large areas now being available for commercial thinning. However, the varying quality of the stands creates a problem. The purpose of this study was to investigate, at the Torsby district of the Stora Enso forest company, how well the present computer records of the stands correspond to reality and determine which stands are, from a qualitative perspective, suited for timber production. Finding variables that indicate better stands would give Stora Enso the possibility of selecting qualitative stands which are more profitable to thin.
The study included 32 stands containing at least 70 % Pinus contorta.
Vad sägs om en förändring? ? En diskursanalys av hur privatisering av bibliotek framställs i Biblioteksbladet
The subject of this master thesis concerns the area of change in libraries, with special orientation towards privatisation. Its aim is to investigate how privatisation is portrayed in one of Sweden?s largest library magazines, Biblioteksbladet, in order to gain insight into why these portrayals are what they are, and what consequences they might get. Three theoretical viewpoints create the general base of the thesis; first, Fairclough?s critical discourse analysis (CDA) theory on the relations between text and society; second, Audunsson?s theory concerning how change is dealt with in public libraries; and third, a conceptual framework on privatisation consisting of definitions and perspectives of the phenomenon.
Att införa Balanced Scorecard : en studie av en implementeringsprocess
Background: In our case study we have been studying a company that during the last seven years have tried to implement the control system Balanced Scorecard. They have during this period made three attempts. According to Kaplan and Norton, the creators of Balanced Scorecard, it should take about 16 weeks to implement a Balanced Scorecard. Purpose: Our purpose is to investigate which factors that influence the possibility to implement Balanced Scorecard. Method: We have conducted a case study where we have studied implementation at three levels in a company.

Miljonprogramsområden tillförs ofta negativa attribut och ses av många som ett stort samhällsproblem. Därför är det viktigt att konkretisera vilka problem som finns för att bättre förstå hur de kan lösas. Två av dessa negativa attribut är ödslighet och rumslig förvirring eller svårigheten att skilja på vad som är privat, gemensam och offentlig miljö. Detta är uppsatsens fokus och konkretiseras genom en fallstudie av ett typsikt miljonprogramsområde. Fallstudien utförs på Byälvsvägen, Bagarmossen, i Stockholm.
Kommer traditionell TV att dö och vad är egentligen TV? : En studie av hur företrädare för TV-branschen ser på play-tjänsternas betydelse för TV
Since a few years back television has been on a verge of an enormous digital change. Web-TV is now growing at an incredible rate and is said to completely change the way we consume TV. The purpose of this essay is to determine and gain an understanding of how representatives of the broadcast industry looks at the phenomenon of web-TV and especially the different kinds of online video services and how they believe this will affect the television. Methods used are qualitative interviews which we compared with previous studies on the subject and acknowledged communication theories. The respondents were people with good insight and understanding of the media and TV industry.
Miljökonsekvenser av dagvattendamm i Skebäck, Örebro : en fallstudie hur miljöpåverkan av en dagvattendamm intill ett Natura 2000-område kan bedömas
Stormwater is surface runoff water that originates from precipitation or snowmelt and that on hardened surfaces prevents to infiltrate the ground. In city areas stormwater can consists of major amounts pollutants and when reaching a lake or watercourse it can cause damages on vegetation and animals. Therefore it is important to treat polluted stormwater before it reaches the recipient.
The municipality of Örebro have since the 90ies an extensive work with treatment of stormwater in sedimentation ponds. A new stormwater treatment project is planned in an industrial estate in Skebäck, Örebro.
Gummigranulatets lekvärde
I allt tätare städer blir gröna oaser av ännu större betydelse för både barn och vuxna. Det finns forskning som pekar på vikten av naturmaterial och vegetation på lekplatser. Trots detta har flera lekplatser som uppförts de senaste åren ett ytskikt av gummigranulat. Två anledningar till varför materialet har börjat användas är dess goda egenskaper som fallskydd samt att det är tillgängligt för barn och anhöriga med funktionshinder.
Huvudsyftet med uppsatsen är att skapa en diskussion kring lämpligheten av gummigranulat på lekplatser. Eftersom gummigranulat är ett förhållandevis nytt material finns det ännu inte så mycket forskning kring dess användbarhet och framförallt inte kring användningen på lekplatser.
Födoval hos juvenil piggvar (Psetta Maxima) : effekter av bytesstorlek
The effects of prey size on prey choice in different cohorts of juvenile turbot (Psetta maxima)were studied in three nursery areas at Gotland. Prey length measurements showed that gobies(Gobiidae) increased in average length during the season, while mysids (Mysidae) did not.Experiments on predation capacity of different size classes of turbot on different size classesof prey showed that juvenile turbot easily can eat gobies that are up to two thirds of their ownbody length, while the body size of turbot does not have any effect on the predation capacityon mysids. Stomach content of 217 turbots, less or equal 35 mm, was analysed to see if therewas any change in diet during the season, but there was no significant change in diet. Theoverall conclusion was that early settlers most likely have an advantage due to greater accessof alternative prey..
Försämrad korrelation mellan storleken av Kebnekaises sydtoppsglaciär och andra klimatindikatorer
Intergovernmental Panel on Climate Change (IPCC) recognizes glaciers as the best land-indicator of climate change. A variety of studies have concluded, using both modeling and field studies, that above all climate parameters precipitation, particularly winter precipitation, and summer temperature controls the change in glacier mass balance. With global warming almost all glaciers on Earth are losing mass. In this study, the summit-glacier constituting Kebnekaise's south summit (called the Southern-summit henceforth), Sweden's highest point, is studied to see how it is affected by winter precipitation and summer temperature during the period 1968?2013.
Vilka konsekvenser har Lex Uggla för fåmansbolag och deras ägare?: -En studie av 50 företag i Stockholm
This thesis analyzes the consequences of ?Lex Uggla? ? a law concerning the boundaries between firm and individual with respect to wealth taxation ? for small businesses, with more than 3 million SEK in over-liquidity. There are two main findings of this thesis. Firstly, the wealth taxation of non-operational assets seems to be an inefficient tax which costs the Swedish welfare system much more than it generates. Secondly, the change in actions among entrepreneurs following the extensive news coverage following the tax authority?s charges against the company of the well-known artist, Magnus Uggla (hence ?Lex Uggla?) illustrates that neither changes of rules nor new applications of rules is necessarily sufficient for an agent to change course of action.

Vattenkvalitén i Fredstorpsbäcken - dikad bäck på fastigheten Rämningstorp i Skara kommun :
The estate of Rämningstorp in the region of Västergötland in southern Sweden is administered by the holding trust company Skogssällskapet i Skövde. In 1999 measures were taken by Skogssällskapet to drain the stream Fredstorpsbäcken as a means to increase the forest productivity of the surrounding lands, which are situated on the estate of Rämningstorp. Almost immediately after the drainage, the streamwater turned turbid and a landowner downstream reported the issue to the county administrative board of the region.
The aim of this thesis was firstly to analyse the suspended matter that appeared during summer/autumn and secondly to explain why it came to be. Initial hypotheses for the explanation to the greyish turbid water were that it was either 1) a chemical/biochemical precipitate, or 2) an bacterial/algal blooming.
Skottbetning på granplantor i Kolmården : omfattning och påverkande faktorer
In the Kolmården area, northeast of Norrköping in south-central Sweden, it was discovered that shoots of spruce Picea abies, plants to a seemingly large extent had been browsed by deer. The area inhabits a dense red deer population, alongside with moose and roe deer, and red deer is thus suspected to cause the damage. The main purposes of this study are, however, to estimate the extent of the shoot-damage and to investigate what factors that may affect the browsing of shoots.
For each stand information was recorded about the age of the plants, area for the stand, height over the sea for the stand, site productivity, type of plants and stand-history.
The study was done in three areas: Simonstorp, Stavsjö and Valinge. At Simonstorp and Stavsjö, respectively, 10 stands were chosen for study and on Valinge six stands. In each stand, 10 plots were sampled.
De externa etableringarnas framtid : en samhällsekonomisk analys av behov och möjlighet till politisk styrning och planering
The out-of-town retail establishments are part of the dramatic structural changes in the retailing of food and groceries. There are however strong indications suggesting these establishments result in negative externalities concerning areas such as pollution and urban environment. The purpose of this study is to describe and, from an economic perspective, analyse the Swedish political regulations and planning policies concerning the out-of-town supermarkets. The analysis establishes that the current regulations regarding out-of-town retailing do not, due to the occurrence of market failures, produce an optimal situation. It might therefore be necessary to change the planning policies in a more restrictive direction.
Strömmar av vatten och politik - en studie om policyprocesser och anpassning.
One of the distinguishing features of successful societies is the ability to adapt to change, bothsocial but also natural changes like climate change. Climate change is a complex, dynamic,non-linear process with a great deal of uncertainty concerning the time perspective, risks andconsequences. A combination of factors like climate change, geographical vulnerability, adensely populated and highly built up coast line along with factors like deficient handling ofsurface runoff and a large usage of ground water leads to an increasingly vulnerable society. Italso puts a greater pressure on the society to have preventive measures in place.The number of actors working with preparing society to the expected impacts of climatechange and variability is increasing. However more than half of Sweden?s municipalities donot consider changing climatic conditions when planning, and many times even allow theconstruction of new living areas in known climatically vulnerable areas.
