Självförsörjande elgenerering : Kan Orust bli självförsörjande på förnybar el?
Orust Kretsloppsakademi is a nonprofit organisation, with a goal of annually generate the same amount of electrical energy that is consumed. Orust is an island on the west coast of Sweden, north of Gothenburg. The population of 15 000 reaches 40 000 during summer, due to the large amount of vacationer. The total electricity demand is 174 GWh a year with a maximum power need of 32 MW. This report presents an analysis for the plausibility of their plan and from a power system stability perspective, the effects on the electrical grid.The conclusion is that the restraints for development of power generation from wind, solar and wave generation, are the power systems capability to transfer power, primarily in the transformers of the grid.
Högriskfonder kontra aktieindex : En studie av makrovariablers påverkan på olika fondalternativ
Abstract Title: High-Risk Funds vs. Mutual- Index FundsA study of macro -variables influence on different funds choice Level: Final assignment for Bachelor Degree in Business Administration Author: Moses Yokie & Bo Lemar Supervisor: Ogi Chun & Cheick Wagué Date: 2011-05-25 Aim: The purpose with this thesis is to compare two different types of mutual-index fond and a high-risk fund in relation to the macro variables. The purpose also includes an investigation about if an investor will receives a higher return on high-risk fund than on mutual-index fund in a 10 years period.Method: A quantitative method has been use in this study, where the information has been received from Morningstar. Microsoft Excel has been used to process the collected data in order to calculate the expected return and the risk measures. The result is presented in graphs and tables on the empirical capital, in order to analyse and compare it with the theories and the selected macro- variables to see if there will be any correlation. Conclusion: This research shows that there is no possibility that the macro-variable factors can benefit an investment on high-risk fund or on mutual-index fund in the short run.
Inverkan av leasingklassificering på konkursrisk - en studie av hur redovisningsbaserade prediktionsmodeller påverkas av en ny leasingstandard
The purpose of this bachelor-thesis is to investigate the possible effects of lease accounting on the estimation of bankruptcy. This is done by estimating the risk via prediction models based on accounting ratios for a sample of 43 listed firms in Sweden. Estimation is conducted twice for each firm, once base on unadjusted data as it is presented in the annual report of 2012, and one with data adjusted for operational leases (that is data is treated as if all leases present were to have been reported as financial leases). In the next step it is tested weather the predictive ability of the models is affected by this adjustment or not. For this purpose translation of bankruptcy risk into synthetic credit ratings via interest coverage ratios is done.
High Cereal Prices : An analysis of the causes behind the increase in the world market price of corn, rice and wheat.
The purpose of this study is to examine which factors played an important role in the food price crisis of 2007-2008. Theories used are Microeconomic theory, explaining changes in supply and demand, and Macroeconomic theory, explaining the impact of changes in exchange rate on prices. A theory regarding speculation is also used to explain the impact of speculative activities effects on price. The method used is multiple regression analysis in order to determine the effects which ethanol production, oil price and dollar exchange rate had on the surge in the price of corn, rice and wheat.The data used is in monthly observations during the period 2005-2008. However, other factors are taken into consideration during the study, such as production quantity, stock size, economic growth, speculative activity and population growth.
Riskhantering och kreditvärdighet : En undersökning av Enterprise Risk Management och dess relation till företags kreditbetyg
Background: Investors use companies? credit ratings as a base in their buy and sell decisions. Companies? credit ratings are also used as indicators of safety in the legislation. This means that credit rating agencies have an important role in the society because they communicate the company?s credit rating to investors and other actors in the society.
Att hjälpa andra trots risk : motivationen i det internationella biståndsarbetet
The purpose of this study is to examine what motivates people to help others at risk to themselves. The focus is on international aid workers, which in their work put themselves in situations of risk. Earlier research shows that international aid work involves risks such as infectious diseases, violence, death threats, assaults, constant insecurity and risk to be traumatized etc. There is not much research done on what motivates to help others in spite of risks, hence we find this an interesting area. We have interviewed six respondents about the content and character of their motivation and factors that are important for the maintenance and development of this motivation.
Självmord : en forskningsöversikt
Suicide is the ultimate outcome of mental illness and is a big and serious problem in society. About 1500 persons commit every year suicide in Sweden and many more engage in suicidal behaviour. This review aims at, from research studies from the 21th century, find out the knowledge of riskfactors regarding the risk for committing suicide among adolescents. The research questions are: What does research say, from a psychobiological perspective, about riskfactors among adolescents regarding the risk for suicidal behaviour? How much does genetic factors have an effect on the risk for suicidal behaviour among adolescents? and : What is the importance of environmental factors such as family connections, friends and school environment concerning suicidal thoughts among adolescents?The method that is used in order to answer these questions is a researchreview including ten research-studies.
Fondplacering i tillväxtmarknader vs mogna marknader
Syfte: Syftet med denna undersökning är att jämföra aktiefonders avkastning i relation till tagen risk för tillväxtmarknaderna Afrika, Ryssland och en mer mogen marknad i detta fall Sverige åren 2008-2011.Metod: Till detta arbete används kvantitativ metod med deduktiv ansats. Information har samlats in i form av sekundärdata såsom fondernas kvartal avkastning från Morningstar.Teori: Standardavvikelse, Sharpekvot och Modigliani-Modigliani måttet används för utvärdering.Slutsats: Studien visar att den Svenska mogna marknadens aktiefonder har högst avkastning och lägst risk. Medan fonder med placering i den mer etablerade tillväxtmarknaden Ryssland har högst risk men varken högst eller lägst avkastning i förhållande till Afrika- och Sverigefonderna. Fonderna som investerar i den nyetablerade tillväxtmarknaden Afrika har låg risk likt Sverigefonderna men även låg avkastning. Samtliga fonder utom en hade negativt värde på Sharpekvot.
Genetisk analys av data från fölbesiktning och jämförelse med resultat vid treårstest :
More than 1000 Swedish Warmblood foals are shown every year at foal inspections which are arranged around the country. Six traits are evaluated at these inspections: type, head-neck-body, correctness of legs, walk, trot and canter. No previous genetic studies have been done on the data from these evaluations. The purpose of this study was to do genetic analyses of the traits which are evaluated at foal inspections. The purpose was also to see if there are any correlations between the results of the foal inspections and the results from the tests of three-year-old horses.
Bedöma Risk för våld hos frihetsberövade : Vad säger forskningen?
Att göra bedömningar av risk för våld hos frihetsberövade personer på fängelser och i olika former av tvångsvård är en viktig del av arbetet med att reducera antalet våldsincidenter, vilket är till nytta både för frihetsberövade personer och för personalens arbetsmiljö. Syftet med denna studie är att göra en kunskapsöversikt över vad forskningen säger om att bedöma risk för våld hos frihetsberövade personer, beskriva aktuell forskning om riskbedömningar, hur strukturerade instrument för riskbedömningar definierar våld, vilka teoretiska utgångspunkter till uppkomst av våld som används och i vilken utsträckning riskbedömningsinstrument tar hänsyn till interaktion mellan personal och frihetsberövade personer.Studien genomförs igenom en litteraturstudie med en innehållsanalys av forskning på området utifrån frågeställningarna i syftet. Sökorden är ?inmate?, ?inpatient?, ?violence?, ?risk?, ?assessment?, ?juvenile? och ?youth?.Reslutatet av studien visar att det finns ett flertal instrument som som forskningen visar har god validitet och även inter-bedömarreliabilitet för att bedöma risk för våld, nämligen Brøset Violence Checklist (BVC), Historical-Clinical-Risk management-20(HCR-20), Dynamic Appraisal of Situational Agression (DASA) och Structured Assessment of Violencerisk in Youth(SAVRY). Utöver detta finns även några bedömningsinstrument som använder enbart statiska variabler för att bedöma risk för våld hos frihetsberövade, även kallade aktuariska modeller.
Ska jag placera aktivt eller passivt? : En studie om premiepensionsvalet
Intention: The purpose of this thesis is to see if an active investment decision in the Swedish Premium Pension System would result in a higher return than a non-active investment decision. A non-active investment decision is equivalent to leaving the money in AP7 Premium Savings Fund.Method: This thesis is a statistical analysis and has a descriptive character in which the calculations are based on secondary data, thus the thesis has a quantitative character. Furthermore three active portfolios in different risk categories have been chosen. These portfolios are compared with the AP7 Premium Savings Fund?s returns.
Två linsrengöringsmetoders påverkan på hornhinnan i samband med användande av kontaktlinsvätskan Opti-Free® Express®
Syfte: Studiens syfte var att jämföra två linsrengöringsmetoders påverkan på hornhinnan. Studien jämförde tillverkarens rekommenderade användningsinstruktioner för Opti-Free® Express®, med den alternativa rengöringsmetoden att gnugga linserna, något som ofta rekommenderas av optiker.Metod: Deltagarna sågs vid två tillfällen för utvärdering av eventuell påverkan på hornhinnan. Värdena som återfanns vid första tillfället fungerade som ett utgångsvärde. Samtliga fynd dokumenterades, graderades och poängräknades efter vilken typ av staining samt utbredning. Cornea delades in i fem regioner; centralt, superiort, inferiort, nasalt och temporalt.
En empirisk studie av Value-at-Risk-prediktering med hjälp av GARCH-modeller
This paper describes a study examining four different GARCH models AR(1)-GARCH(1,1), AR(1)-EGARCH(1,1), AR(1)-APGARCH(1,1) and AR(1)-GJR-GARCH(1,1), and their ability to predict future volatility and thereby providing more reliable estimates for Value-at-Risk. The study is based on daily observations for the return of the OMX Stockholm 30 Index, during the time period 31st December 1996 to 29th December 2006. The coefficients for these GARCH models have been estimated using a five-year rolling estimation window, with one-year lags, for five different in-sample-periods. These five in-sample-periods, and the coefficients given by them, have been used to generate five out-of-sample predictions for the volatility in each year. Using these volatility predictions, the daily Value-at-Risk has been calculated for confidence intervals of 90 percent, 95 percent, and 99 percent, respectively, during the time period between 1st January 2001 and 29th December 2006.
Delta på lika villkor? : En studie om ekonomiskt utsatta barns skolsituation sett utifrån ett lärarperspektiv.
The aim of this essay was to create an understanding of teachers strategies to respond to children in economic hardship in school and if these children can participate on equal terms in school. To examine this, we chose to do semi-structured interviews which is a qualitative method. Eight teachers were interviewed from four different elementary schools. In our interviews, we found that all the schools both had elements of inclusion and exclusion, which can result in both equal and unequal terms for participation in school. We also found that the school with the most students in economic hardship had the most inclusive strategies.
Fonders avkastning -en variabelanalys av fonders avkastning under ekonomisk upp- och nedgång
Vårt syfte är att ta reda på mer om vad som påverkar fonders avkastning och om detta skiljer sig åt i ekonomisk uppgångs- respektive nedgångsperiod. För att uppfylla vårt syfte har vi använt oss av regressionsanalyser med avkastning som beroendevariabel och variablerna: standardavvikelse, beta, storlek, TKA och omsättningshastighet som förklarande variabler. Vi har använt portföljvalsteori med dess ingående variabler avkastning och risk. Även begrepp som CAPM och beta gås igenom. Detta följs av det aktuella forskningsläget inom ämnet.
