Barkar det åt skogen för svenskt tidningspapper? : empirisk analys av efterfrågan och företagsstrategier på den svenska marknaden
According to Food and Agriculture Organization newsprint is defined as: Uncoated paper, unsized (or only slightly sized), containing at least 60 percent of mechanical wood pulp. The consumption of newsprint in Sweden was just over 798 000 tonnes in 2009, which represents approximately 90 kg per person. Although there are studies that predict a drastic reduction in newsprint consumption in the Western world, there seems to be a clear difference between forecasts for the future given by statistical analysis of newsprint consumption and forecasts given by experts in the industry. The former predict a continuing increase while the experts see a coming decrease in consumption.In this report, both demand and business strategies of newsprint in Sweden are studied. The study also presents a forecast of the future which is based on historical data and qualitative interviews.
Hastigheter på lokalgator: en studie av gaturummets påverkan
En gatas geometriska utformning är av betydelse för de val vi gör längs en sträcka.Det kanske viktigaste valet är hastighet, vilket är nära kopplat till olyckor och kan påverka en känsla av otrygghet längs gatunätet. Dimensioneringsfaktorerna på det vägnät vi har idag skiljer sig vitt åt, genom varierade gatubredder och korsningsavstånd men även olika högsta tillåtna hastigheter för vägar med samma dimensionering. Hastigheter påverkar människor både direkt och indirekt, och kan ge upphov till mycket svåra skador för den enskilda. I ?Nollvisionen? anges långsiktiga mål som eftersträvas vid svensk transportplanering.
Kapitalstrukturens inverkan på företagsvärdet : -En kvantitativ studie av den svenska aktiemarknaden
Background: During extreme market conditions like the period during fall 2008 the discussion of what affects company value becomes apparent. The capital structure is the relation between borrowed capital and equity in a company´s financing mix. What impact changes in capital structure have on company value is a widely debated subject within the theory of finance. If a relationship between capital structure and company value exists the implication is that an optimal capital structure where company value is maximized also exists.Aim: The aim of the thesis is to study whether a certain relationship between capital structure and company value exists among selected stocks and companies listed on Stockholmsbörsens OMXS30.Implementation: With aim to fulfill the purpose of the thesis regression analysis has been performed among chosen stocks and companies. The empirical results eventuating from this have been analyzed from the view of elected relevant theory.Completion and results: We find that during normal market conditions a positive relationship between debt ratio and enterprise value (EV) can be established.

The empirical study is implemented by the simple linear regression model and a vector autoregressive model (VAR).
Kalcium- och fosforsmältbarhet hos växande hästar
In the latest edition of NRC (2007) the feeding recommendations for Ca and P to growing
horses were increased with 35 and 25 %, respectively, based on results from a Canadian study
showing that daily endogenous fecal losses of Ca and P were greater than previously
suggested. A Ca absorption efficiency of 50 % is used for all horses. However, the true
absorption efficiency might be as high as 70 % in young horses. P absorption efficiency is
assumed to be higher for growing horses because their diets are often supplemented with
inorganic P. Thus, an efficiency of 45 % is used for growing horses as compared to 35 % for
mature horses.
Följa John på räntemarknaden
SYFTE: Syftet med detta arbete är att undersöka det eventuella sambandet mellan de utvalda ländernas ränteförändringar och ränteförändringar i Sverige. Vi undersöker även om det går att påvisa om något eller några av ländernas räntor påverkar räntorna i Sverige. Vidare är syftet att ta reda på vilken inverkan de utvalda EMU-länderna har på den svenska räntan. Vi undersöker även hur volatiliteten ser ut för ränteförändringarna i de olika länderna jämfört med ränteförändringarna i Sverige. METOD: Vi har i vår uppsats använt oss av en kvantitativ metod med komparativ design.
Pappa, mamma, barn och psykisk hälsa : Socialt stöd från föräldrar i relation till psykisk hälsa
Mot bakgrund av socialisationsprocessen och de rådande genusnormerna som verkar inom denna, ämnar den här studien undersöka huruvida sambandet mellan socialt stöd och psykisk hälsa bland barn och unga varierar enligt könskompositioner mellan föräldrar och barn. Ytterligare ett syfte är att studera om ovanstående samband skiljer sig mellan äldre och yngre barn.Uppsatsen är kvantitativ och studiens analyser baseras på empirisk data från Barn-LNU och Barn-ULF (2000-2001). Analyserna genomförs med linjär regression med hjälp av statistikprogrammet SPSS (n=1,964).Resultatet visar att det finns ett samband mellan socialt stöd från föräldrar och psykisk hälsa bland barn och ungdomar i åldrarna 10-18 år. Detta gäller dock inte alla aspekter av socialt stöd. Resultatet visar vidare att den psykiska hälsan varierar enligt kön; pojkar har bättre psykisk hälsa än vad flickor har.
Sambandet mellan psykisk ohälsa och hälsorelaterade levnadsvanor bland kvinnor och män i en skånsk befolkning
Bakgrund: Daglig rökning och låg fysisk aktivitet på fritiden är betydligt högre bland individer med psykisk ohälsa.
Syfte: Att undersöka dessa samband i ett köns- och socioekonomiskt perspektiv, samt eventuellt finna bakomliggande orsaker.
Metod: Använder data från en tvärsnittsstudie (Folkhälsoenkät, Skåne 2000) med en representativ population (n = 11 304) i åldern 18-65. Huvudvariabler är självrapporterad daglig rökning och låg fysisk aktivitet, samt psykisk ohälsa som bedöms via General Health Questionnaire-12. Analyser gjordes med logistisk
regression för att få oddskvoter och kontrollera för möjliga confounders.
Resultat: Samband finns mellan psykisk ohälsa och daglig rökning, respektive låg fysisk aktivitet bland båda könen, och bland socioekonomiska grupper. Kvinnor har signifikant lägre oddskvoter gällande båda sambanden. Individer med psykisk ohälsa har fler ofördelaktiga levnadsvanor än de med ej psykisk ohälsa, oavsett socioekonomisk status.
Kan relationen mellan CSR och lönsamhet stödja svenska finansbolags undermåliga samhällsansvar? - En kvantitativ studie med beaktning av endogenitetsproblemet
Introduction: The concept of CSR was first coined in the 1950?s and refers to corporate vol-untary work to contribute to a sustainable society. In Sweden, companies within the finance sector are among the worst when it comes to implementing CSR in their daily work. The debate on whether companies should engage in CSR activities or not, is extremely relevant nowadays. Right now we are facing a time where the demand on companies to take their social responsi-bility becomes more intensified.
Vem använder budget? : En kvantitativ undersökning av budgettillämpningen i olika organisationer
Weber and Linder (2005) have enlightened that the focus of the current debate on the budget?s to be or not be, has been on trying to find a general tool, which fits best in all situations. They argue that the budget may be more appropriate for organizations in certain circumstances, than for others. They claim that there is a gap in research concerning the situations in which the budget may be appropriate, or when Beyond budgeting is preferred. It is this gap we are trying to fill with our thesis.The purpose of the thesis is to explain which situational factors that affect the organization's use of budgets for the functions the budget can fulfill.
Bull´s Eye? : Träffsäkerheten i analytikers prognoser

The recent years´ development in the stock market has lead to criticism of analysts? deficient forecasts. Purpose: The purpose of this thesis is to evaluate analysts´ forecasting ability concerning companies quoted at Stockholmsbörsen between 1987 and 2002. We also intend to discuss possible explanations for analysts? behavior in case of deficient accuracy.
Är Leviathan giftig? : Autonomi och repression som förklaringar till regimskillnader i förväntad livslängd
During the last decade a number of studies have been published that investigate how the most fundamental aspect of political organization, the regime type, affects population health. The results unanimously show that citizens of democracies live longer and healthier lives than citizens of non-democracies. Many explanations for this have been suggested, among these are that democracies redistribute more and invest more in salutogenic resources, and that the tendency of dictatorships to control the media negatively affects the ability to spread information crucial to public health. When these mechanisms are controlled for, however, it turns out that democracy has a large residual correlation with for example life expectancy, which suggests that other mechanisms are also involved.In this paper two new mechanisms regarding the possible psychosocially mediated health effects of the regime type are investigated, namely political repression, and the possible negative effects this might have on the levels of chronic stress, and autonomy, which connects to a large previous literature in social epidemiology. In the paper an ecological cross-country design is used and country-level data, provided mainly by the World Bank and Freedom House, is analyzed with a simple multiple OLS-regression model.
Logistik i små företag - En analys av problem och möjligheter för STARKA
In order to suggest improvements for the logistics of STARKA, we felt that we had to analyze all the activities which were related to STARKA's logistic processes. Our primary analysis consisted of a rough but comprehensive description of different functions in the company, and the relationship between them. This was performed by following a typical order through the company to see which functions were affected by the order.Since we needed a more thorough view of the company, we decided to analyze the different products STARKA currently has on the market, focusing on economic data such as turn-over, profit, profit margin, deficiency cost and cost of warehousing. We also analyzed the company's choice of manufacturing processes, organization, warehousing processes, strengths and weaknesses.These analyses gave us a clear understanding of the company and its processes. STARKA is a small, function oriented company with a wide range of products.
Effektivisering : En utredning om åtgärder på en industrifastighet
AbstractDelta Terminal owns an outdated industrial building which they now rent out to businesses. This property currently has a high energy con-sumption and therfore it is desirable to improve the efficiency. In ordet to reduce the energy consumption within the industrial building enve-lope, the heating systems and lighting are being investegated. A good building envelope emits less heat and thus reduces the energy consump-tion. An energy audit is a tool used to determine the energy loss.
