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.

There is an irregularity in the interregional migration in Sweden. An increasing proportion ofthe population is drawn to the metropolitan areas, which creates problems for the smallermunicipalities and towns when their population declines. At the same time, our whole societyis faced with a great challenge: we need to redirect towards a sustainable development, wherethe environmental issues are discussed and dealt with to secure that all present and futuregenerations are given equal opportunities to live a good life.The aim of this study is to, focusing mainly on the environmental dimension of thesustainability concept, examine the attractivity of housing with sustainability claims. Toanswer this, three research questions were used:? Was the migration motive to reduce their environmental impact a part of the decision tomove, among migrants who had moved to housing with sustainability claims?? If the motive was a part of the decision, how much impact did it have compared to othermigration motives?? Which factors in housing aiming at sustainability are considered important by peopleliving in housing with sustainability claims?The research questions have been answered using quantitative data, gained in the form of selfadministeredquestionnaires which were distributed in four different residential areas withsustainability claims in the county of Västra Götaland, Sweden.

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.

Swedish studies have shown that more people than expected have problems with leg ulcers and that the yearly cost for treatment per patient is approximately 26 500kr. Since the elderly population is on the rise, there is a need to highlight this growing problem, to make sure that proper assessment tools are used and to improve the standard of care given to patients with leg ulcers. The aim was to show what a difference the nurse can make to patients with leg ulcers. With all types of wounds it is imperative to establish if there is any underlying reasons since certain illnesses can cause more wounds or delay the healing process. The doctor is responsible for making the diagnosis and to prescribe the correct treatment whereas the nurse?s responsibility is for the nursing care and its documentation.

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.

Metakognitiva processer och förmågor innefattar bland annat människans förmåga att reflektera över sin egen kunskapsnivå och minneskapacitet, och att utifrån detta till exempel kunna reglera tid och inlärningsstrategier vid inlärningssituationer. Kännetecknande för en person som räknas till att vara expert inom en viss domän är bland annat att denne anses kunna övervaka sin kunskapsnivå på ett korrekt sätt. Denna studie undersöker om personer med stor domänkunskap uppvisar en större förmåga till metakognitiv övervakning än vad personer med sämre domänkunskap gör. Aktuell kunskapsdomän i denna studie är deklarativ kunskap kring fotboll, och fotbollsspelare och ledare rekryterades som försöksdeltagare. Förmågan till metakognitiv övervakning mättes med hjälp av mätteknikerna Assessment of Cognitive Monitoring Effectiveness (ACME) och Metacognitive Knowledge Monitoring Assessment (KMA), där försöksdeltagarna i samband med att ett kunskapstest genomförs får avgöra vilka frågor de tror sig kunna eller inte kunna svaret på.

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.

This master's thesis aims to explore the field of evaluative bibliometrics. In short, this field of research uses bibliometrics - i.e. the application of mathematical and statistical methods to books and other media of communication - as a research assessment tool. In recent years, evaluative bibliometrics has been an increasingly used method in research evaluation and is today used and implemented in many countries worldwide. Today, in Sweden, we can also see that evaluative bibliometrics is highly recognised and, in some cases, used in practice.

On-site sewage systems are common on the countryside of Sweden with approximately one million on-site systems installed. Due to insufficient function, these contribute significantly to the total discharge of phosphorus to rivers and lakes, causing eutrophication. In order to reduce eutrophication and to fulfil one of the environmental quality objectives, the decision was taken by the Swedish Government in 2005 that 60 % of phosphorous in sewage sludge is to be recycled to arable land before 2015. To make recycling a reality, new solutions have to be found. Federation of Swedish Farmers (LRF) takes an active interest in this issue and has initiated this study. One problem is that the food industry is sceptical towards recirculation due to the risks that products from sewage systems may contain pathogens, heavy metals and unwanted chemical compounds, e.g.

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.

The objective of this study was to explore the mechanisms controlling elderly people's choice of staying in there own home.The main questions were: What makes some people move to retirement homes while some people stay in their own home? What is the emotional relation to housing for people in general and elderly people in particular? How does the assessment of aid and application of the law affect elderly people's possibility to choose their way of living? What mechanisms during the twentieth century have controlled the society's way of looking on elderly people's housing? What future scenarios can we expect concerning elderly people's housing?Our method consisted of a literature study combined with qualitative interviews.The authors found a complex picture concerning elderly people's relationship to their housing and the will, wishes and possibilities to move to a retirement home or stay in their own home. One factor that affects elderly people's will to move is a deteriorated health. Another is the increased need of a safe living and access to personnel at all time. Also the assessment of aid and application of the law affect elderly people's possibility to stay at home or to move to a retirement home.

Time Perspective is related to mental and physical health. This study examines the relationship between Time Perspective and perceived stress where Time Perspective was expected to predict the level of perceived stress. Past-negative, Future-negative, Future-positive and present-fatalistic were expected to be positively associated with perceived stress while Past-positive and present-hedonistic were expected to be negatively associated. Measures from the self-assessment forms S-ZTPI, PSQ-recent and CES-D from 445 participants (242 women, 203 men) between 60-90 years were used to examine the hypothesis of the study. Two hierarchical multiple regression analysis confirmed that Time Perspective is associated with perceived stress and in part 2 explains it's variance, one when adjusting for demographic data (.R = .37) and the 2 other when adjusting for demographic data and depressive symptoms (.R = .13).

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.

The idea for the project emerged when Nilorn wanted to get better control over their supplychain and improve operational efficiency. The company also want to reduce their expenses inthe continuous process of improving profitability. By choosing the right option oftransportation and mode of transport there are large potential savings for the company. Thisenables Nilorn to reduce the transportation costs and strengthen the environmentalresponsibilities by reducing their environmental impact.The flow of goods within Nilorn has over the past years increased significantly and most ofthe gods today is transported by air. The aim of this thesis is to analyse the supply chain of thecompany and evaluate the potential economic savings in this area.

This paper is intended to provide a picture of which associations water can wake in the human mind from the perspectives of garden history as well as from that of environmental psychology. I hope to paint a fairly broad picture of our perception of water that can serve as a basis for discussion and as a starting point for different forms of design work in landscape architecture. The historical perspective emphasizes the importance of water as a condition for the emergence of gardens and in a wider perspective the importance of water in early cultures. Also, I describe a picture of how water has been used throughout the history of gardens from early Egypt to the baroque era. The garden history analyzed from an art historical perspective gives a picture of human associations to water, and the history behind these associations is presented. As a compliment to the art history approach, I have chosen to highlight our associations with water from the perspectives of environmental psychology and evolutionary science.
