Forest fertilization had its peak in the late 60´s, when almost 200 000 ha was fertilized annually. The silviculture of today has high demands for timber production at the same time as the demand for nature conservation increases. It means that it?s necessary to produce more volume in smaller areas in the future. The use of DGPS equipment has in modern forestry in Sweden become more and more common.
Gravar i Alsike hage : Analys av fyndkontexter och gravkonstruktioner tillhörande gravfältet RAÄ 26 i Alsike socken, Uppland
This essay deals with the results and observations made during excavations in an iron age cemetery in Alsike hage, located in Alsike parish. The excavations took place in 2005 and 2006 and the investigated area comprised two adjacent, but secluded burial-constructions; a square stone setting with a secondary grave, and a stone-built terrace with at least one secondary grave. The artifacts suggests that the TPQ of the stone setting, and the construction date of the rest of the graves, is 900-950 A.D. The aim of this study was to comprehend the course of events in the investigated area, and toanalyse the archaeological finds - in comparison to the well documented an discussed material burial culture in the lake Mälar area ? in order to discuss indicators of gender and social status.Metal artefacts has been preserved as a part of the analysis..
Ungdomsbrottslighet : Ungas föreställningar om varför ungdomar begår brott.
Den första januari år 1999 upprättades ett nytt statligt pensionssystem i Sverige. Det gamla systemet ATP ersattes av ett nytt system; den allmänna pensionen. En del av den allmänna pensionen blev premiepensionen. Den delen av den allmänna pensionen är ett fonderat system där pensionsspararen själv kan välja hur det inbetalade pensionskapitalet ska placeras. Idag finns det drygt 800 fonder för pensionsspararna att välja bland till sin premiepension.
Att beskriva etnografiska föremål med hjälp av ämnesanalys och ämnesindexering
The aim of this masters thesis is to analyze how subjects of ethnographical objects should be described. To obtain this we focus on which subject aspects of ethnographical objects that could be possible and valuable to analyze and to index. This is done with the help of established LIS subject indexing theories, and through the perspective of ethnographical museum documentation. The theories are both general, concerning the stages of subject indexing, and more specific, regarding the indexing of pictures. One of the latter is the theoretical model of Sara Shatford, from the article Analyzing the Subject of a Picture.
Anseende - Hot or Not? : En explorativ studie i hur stora svenska företag ser på begreppet anseende
There are many views in the concept of corporate reputation and the massive research in the area tends to result in many new definitions. Research has shown that a good corporate reputation has a positive relation to Sustainable Competitive Advantage, financial performance and attraction to competent employees. The many views in the concept make it especially interesting to examine the view on corporate reputation in a perspective of big Swedish corporations. Another interesting area to examine is whether the companies manage their reputation or not. The empirical findings of this essay are based on qualitative interviews to get a deeper understanding in the area of reputation.

Naturvårdsrestriktioners effekter på brukandet av ädellövskogen i Skåne :
Restrictions in nature conservations are increasing the influence of forest management. Nobel broadleaved forests are more influenced than other forests, because they are considered to be more valuable than other forest types in Skåne. There has been a lack of knowledge about the amount that is set-aside for nature conservation and what types of forest that is concerned.
These are the main questions to be answered in this thesis. Moreover has the timber quality been compared between set-aside and non-set-aside areas since it affect the financial conditions for the forestry in nobel broadleved forests. The last asked question deals with the financial consequences of set-aside.
Boksomäromöjligatthitta?: En studie av de sociala taggarna i Stockholms stadsbiblioteks OPAC

My starting-pointis that the tags are a form of utility texts.What I find is that a clear majority of the tags are nounsand function as index terms, but that there are differencescompared to authorized index terms.
Korruption : en kulturell förklaringsansats
Syftet med denna uppsats är att pröva om kulturella faktorer kan förklara den mellanstatligavariationen av korruption. En teoretisk genomgång pekar ut Transparency Internationals CorruptionPerception Index, samt Världsbankens Control of Corruption Index som lämpliga indikatorerpå graden av korruption. Som kulturella förklaringsfaktorer används två dimensionersom den amerikanske samhällsvetaren Ronald Inglehart (1997) extraherat ur det världsomspännandeWorld Values Survey-materialet; dessa dimensioner avspeglar en tvärkulturellpolarisering mellan traditionella visavi sekulära värderingar och överlevnadsvärden visaviemancipativa frihetsvärden (Warelius 2007). Inglehart och Welzel (2005) har lagt fram empiriskbevisföring för att socioekonomisk utveckling orsakar kulturell förändring, således användsdenna faktor som bakomliggande kontrollvariabel ? FN:s Human Development Indexnyttjas som indikator på socioekonomisk utveckling.Flera teoretiker framhäver närvaron av formella demokratiska institutioner som en förklaringtill graden av korruption.

Kloridhalter i gran utmed en depositionsgradient för havssalter :
The knowledge of the chloride content and its fluxes and patterns in trees is insufficient. Increased knowledge would be desirable, one of many reasons is to be able to more efficiently meet the problems that the substance causes in the pulp industry. The purpose of this study was to examine and describe the chloride concentration of Norwegian spruce (Picea abies L. Karst.) in the south of Sweden. Furthermore the aim was to be able to predict chloride concentration from readily measurable site factors.

Hur underprissättning påverkar efterföljande prestation
This thesis examines underpricing and the long run performance of IPO firms on the Swedish equity market during 1994-2010. We further investigate whether any correlation exist between underpricing and post-IPO performance during 36 months. We use a sample of 80 IPO firms. To examine the aftermarket performance we compare total return of each firm with a matching industry index. In order to strengthen our analysis, we run a second test, comparing actual return for each firm with expected return, adjusted for firm specific risk.
Utformning av hamnområdet i Arvika : stadsbild och offentliga miljöer
The harbour in Arvika is closed down and the industry that has been established in the area is now beeing wound up. A deepened comprehensive plan for the area is under progress in the municipality. The intentions are for instance that the harbour should be integrated with the city and that Arvika is facing a lake should be more apparent from the city center. The harbour should also contribute to a more attractive city. These intentions have hence been the starting point of my undergraduate theses, which has resulted in a proposal on how to develop the harbour.
During the process I have analysed the city image, how the area is used today and the public places in the city centre.
Marknadseffektivitet - en studie på den svenska fondmarknaden
Huvudsyftet är att undersöka om det existerar väsentliga variabler som kan hjälpa oss att finna framtida vinnarfonder genom att studera historisk information. Studien mäts i förhållande till det existerande utbudet på svenska fondmarknaden. Konkret vill vi kunna få en högre signifikant avkastning under en given period än den genomsnittliga avkastningen för samtliga fonder på den svenska marknaden. Med denna undersökning vill vi bidra till en diskussion om det råder marknadseffektivitet. Variabler som vi studerar för denna undersökning är historisk avkastning, standardavvikelse, Sharpekvot, Stutzer index, fondstorlek, kapitalflöde, relativ volym, trading activity, fondavgifter och slutligen ålder.
