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.

Alien plants that have intentionally been introduced to an area for cultivation in public or private gardens constitute the primary pathway of introduction for invasive alien species that spread into nature. Garden owners want species that have satisfying characteristics, these characteristics are often also linked to plant invasiveness. Thus, the horticulture industry plays an important role by making scientifically based decisions and phasing out invasive plants and replacing them with alternative species with satisfying characteristics, but low risks of becoming invasive. This thesis aimed to examine the sale of and the attitudes towards alien plants in the horticulture industry in Sweden. Alien terrestrial plants identified to have a severe risk, high risk or potentially high risk of spreading and becoming invasive according to ArtDatabankens assessment, were examined to see if they were for sale.

Problematiken i strategiska samarbeten avseende varumärkesutvidgning ligger i att skapa en gemensam grund för användandet av varumärket, för att undvika varumärkesförsvagning. Det är svårt att förutsäga hur den andre parten kommer att agera och använda varumärket, vilket innebär en risk. Syftet med vår undersökning är att studera hur kommunikation, avseende relationen samt varumärket, tar sig uttryck i ett strategiskt samarbete som bygger på varumärkesutvidgning. Resultatet visar att genom att kombinera formell och informell kommunikation kan ett företag föra över sitt varumärke till ett annat företag, men för att förankra detsamma krävs även att hänsyn tas till kontexten, i vilken mottagaren verkar. Genom samma kombination byggs en relation som baseras på förtroende, vilket kan underlättas genom gemensamma erfarenheter samt val av ett visst språkbruk.

Syfte: Undersöka den kriterierelaterade validiteten, mellanbedömarreliabiliteten och användarvänligheten för MEONF, ett screeninginstrument för bedömning av risk för undernäring. Metoder: Hundra patienter inkluderades och nutritionsstatus bedömdes med Mini Nutritional Assessment (MNA) som här anses vara golden standard samt screenades med Malnutrition Universal Screening Tool (MUST) och Minimal Eating Observation and Nutrition Form (MEONF). Resultat: Sjuksköterskorna ansåg MEONFs instruktioner och frågor lätta att förstå, svara på (100 %) samt att frågorna var angelägna (98 %). Instrumentet hade acceptabel sensitivitet (0.83) och specificitet (0.78) jämfört med MNA. Sensitiviteten var högre än den som fanns mellan MUST och MNA (0.57).

Purpose: The purpose of this study is to examine whether hedge funds generate higher risk-adjusted returns than traditional managed funds in Sweden.Methodology: This study was based on quantitative data about the funds historical returns. The funds historical returns were taken from the database Morningstar and the risk-free rate from the Swedish central bank. Random samples of 36 funds have been divided into three portfolios in the form of a hedge fund portfolio, stock portfolio and mix fund portfolio.Result & Conclusion: The study concluded that the stock portfolio has shown the highest average yield for the study period where all portfolios below market index. Hedge fund portfolio has achieved the highest risk-adjusted return calculated by the portfolios Sharpe Ratio. Of all hedge strategies, arbitrage had the highest average return and risk-adjusted returns..

Background: In 1999 the Swedish pension system was reformed with an aim to create a stable and high return on pension assets. First, Second, Third and Fourth general pension funds, hereby referred to as AP1-AP4, had an important part in the reform. AP1-AP4, also called the buffer funds, was assigned to secure long-term, big parts of the pension capital. The funds objective is by law, to manage the fund's assets in a manner that provides maximum benefit for the state pension. The funds will also invest pension assets with an overall low level of risk while achieving a sustainable high return.Aim: The purpose of this study is to investigate whether the First-Fourth AP-Funds is meeting its objectives regarding risk and return according to Swedish law.

AbstractIntroduction: Hand Arm Risk Assessment Method (HARM) is a tool to assess the risks of deve­lo­ping complaints of the arm, neck or shoulders during manual work. The method was developed in the Netherlands primarily for employers, but is also used as an aid to work environment in­spec­tors. The purpose of this study was to evaluate the HARM-method for assessment of biomecha­nical exposure of the upper limbs when performing manual tasks as well as its suitability to be used within work environment inspection. Methods: Ten labour inspectors conducted assessments of five video-recorded work tasks. Assess­ments made with HARM were compared with those made with the Assessment of Re­pe­titive Tasks (ART) tool and with ACGIH Hand Actvity Level (HAL) - both methods for assess­ment of bio­mecha­nical exposure of the upper limbs - and with the model for the assessment of re­pe­titive work in the pro­visions of the Swedish Work Environ­ment Autho­rity on ergonomics for the prevention of mus­culo­skeletal disorders, AFS 1998:1.

Studien handlar om stickskador och skador med vassa föremål inom hälso- och sjukvård. Dessa skador är en risk som hälso- och sjukvårdspersonal utsätter sig för i sitt dagliga arbete. Stick- och skärskador är direkt förenade med risk för blodburen smitta såsom HIV, HCV och HBV. Litteraturstudien baserades på befintlig kvantitativ forskning och syftet med studien var att i vetenskaplig litteratur undersöka vilka faktorer som kan påverka sjukvårdspersonals hantering av stickande/skärande föremål. De faktorer som identifierades var; personrelaterade orsaker, materiella orsaker samt organisatoriska orsaker.

Investors? use borrowing as a way to profit from leverage advantages in their portfolios.When investors borrow with their securities as safety for the loan and the value of thesecurities decrease the investor can get a portfolio with more credit than what is covered bythe value of the securities and risk huge losses. To what extent an investor is allowed toborrow with his portfolio as safety depends on the bank or broker and varies between theproviders. By studying available material and in addition to that making an empirical study Iattempt to find out the reason for the varying degrees of leverage possibilities between thebrokers and how the degree of maximum borrowing on the securities are decided. Thefindings show that decision of leverage degree on a security is made after first making aquantitative analysis of the stocks volatility and liquidity and thereafter make a qualitativeanalysis of the company.

Syftet med vår litteraturstudie är att beskriva hur en livsstilsförändring och livstilsskillnader kan påverka utvecklingen av det metabola syndromet, samt hur sjuksköterskan kan medverka med hjälp och stöd vid livsstilsförändringar. Frågeställningar är: Vad är effekten av en livsstilsförändring vid risk för metabolt syndrom? Hur kan sjuksköterskan medverka till prevention av det metabola syndromet? 10 vetenskapliga artiklar användes i litteraturstudien för att besvara ovanstående frågeställningar. Resultatet i denna litteraturstudie visar att en livsstilsförändring har en stor och avgörande betydelse vid risk för utvecklande av metabolt syndrom. Denna studie visar även på att sjuksköterskan, genom att ge individuell rådgivning och stöd i form av kontakt via telefon, Internet samt sedvanliga mottagningsbesök har en betydande roll i preventionsarbetet vid detta tillstånd.

The issue of honour related problems in schools are important social problems in Sweden. It?s not unusual that honour related problem has had serious consequences before any action has been inserted by society. Sometimes the efforts made by society have had no impact whatsoever due to them being inserted too late. We can conclude based on our literature and our interviews, the importance of prevention.
