This essay deals with the social services cooperation with the private sector relating to foster care. The aim was to examine whether and what the causes may be that the social service transfer tasks of authority to private actors. Furthermore, we have examined and discussed if such a working procedure can lead to consequences for the individual child and how / if the children's legal security is affected. Survey methodology is qualitative in nature where we conducted semi-structured interviews with three persons who work in different ways to be involved in work with a foster family. We have also made use of questionnaires sent to social workers around the country.The result has been interpreted on the basis inter alia, legal texts, legislative history, and two theories which have their origin in organization theory.

This paper aims to explore the relationship between financial risk and ESG scores in order to assist investors in making investment decisions. We investigate the hypothesis that there is a relationship between the ESG score of a company, and the financial risk in terms of volatility in the relevant company?s share price. The paper is grounded in sustainability reporting and financial risk. With the world facing significant changes and natural disasters, there is an urgent need for action to mitigate environmental impacts to avoid devastating consequences.

To be able to evaluate different radio waveforms in a laboratory environment FOI in Linköping has developed an experimental system for radio communication called Rasmus. The system consists of a transmitter, a channel emulator and a receiver. The transmitter modulates a digital signal to a desired analogue waveform. The channel emulator is used to simulate a real radio channel. The channel emulator distorts the signal by splitting it up in several propagation paths.

This thesis examines a possible control strategy to minimize flow fluctuations in Uppsala?s district heating system. High variations in flow rate may lead to complications caused by hydraulic constraints in the district heating system. These complications, such as inadequate pressure and temperature levels, increase the risk of heat delivery failures. It is therefore important to avoid such situations both for the producer and for the customers.Typically, the forward temperature is controlled by using a rough correlation with respect to the outdoor temperature.

The objective for this master?s thesis was to test and evaluate two methods for determining the content of tannin in a pinebarkextract. The methods used at Södra for this previously have not been specific enough, only the amount of polyphenolics have been measured. One of these methods is a test based on the Stiasny test and it determines the extracts ability to form a gel with formaldehyde. When this test was carried out it showed that the extract did not contain much tannin.

Hälsans Trädgård is a project which is going to start in Gamla Linköping, Sweden. The authors were commissioned by Arbetslivsresurs, a company working with work rehabilitation, to select, define and make job analyses on five work tasks at Hälsans Trädgård in Gamla Linköping. A job analysis means an analysis of the demands the job make of the individual. The job analysis used in this study is called The Revised Handbook for Analyzing Jobs (RHAJ) and is from the US Department of Labor (DOL). As RHAJ is an American instrument, the authors produced a form where the concepts are translated into Swedish to make the analysis easier.

Different field tests are currently used in a wide extent in different levels of soccer teams. To be able to assess the players? physiological status the tests must have high validity, reliability and external validity. Many different tests have been developt, but currently only five of these tests are most commonly used: Yo-Yo intermittent recovery test (YIRT), Yo-Yo intermittent endurance test (YIET), Multi-sprint-test, Beep-test and Cooper-test. Presently there is no definitive conclusion regarding which of these tests is most suitable for soccer players.

My main purpose with this study is to investigate how the social worker relates to knowledge, power and profession. From this purpose has also the concept ?to be a social worker? emerged.The study is based on a qualitative study and consists of semi-structured interviews with seven social workers from different fields of expertise.The result of the study shows that the knowledge is dependent of different fields of expertise. But in the contact with the client, regardless of field of expertise, the knowledge is gathered through a reflective pattern. Through theoretical attempts and earlier experience from social workers, this is brought to life in this unique meeting.

North Korea is considered to be the most autocratic dictatorship in the world today. Its citizens are denied their most basic human rights and North Koreas ambition to pursue nuclear weapons is looked upon with great fear from the international community and the US in particular. Some experts say that the threat from North Korea is far greater than the one possessed by Saddam Hussein. Although North Korea seems to inhabit all the necessary criteria for an US military intervention the United States has openly declared its diplomatic ambitions with the state. Why?With the use of realist and social construction theory this study will bring clarity to why the United States prefers diplomacy instead of a military intervention.

Companies in the western world can no longer compete by using traditional means such as product and price since the commerce of services continually grows. To avoid similarity and increase competitive advantages modern companies have to be more specified. The competition between companies has increased and customers are harder to reach. Customers of today can afford luxury but trend indicates that originality, identity, and status are more important than factual needs. Products created and consumed at the same time within the service market are often very homogenous (similar).

This final thesis was performed at Ericsson in Gävle between April and June of 2008. Ericsson is a world leading manufacturer of radio base stations (RBS), which handles mobile phone traffic with 2G and 3G technology. The main purpose of this study is to examine if two different types of products (RBS and site material) should have different terms and conditions, today the terms and conditions are the same for both types. During the course of our study we have tried to think of the terms reliability, validity and generalization. The intention in doing that was to keep the thesis at a high academic level. To name an example of this we have tried to keep our minds at an objective level during the interviews and informal conversations.

Sustainable Development is often described as a balance between ecological, economical and social aspects. Between these exists a complicated interaction that creates conflicts in the planning of the landscape. We see a growing need for a functional interaction between values and interest and an understanding for different perspectives. Cooperation and dialogue are key ideas with the focus on cooperation rather than the goal. There is a lack of forum for dialogue and cooperation within municipalities where a great knowledge and competence are gathered.

The purpose of this literature study was to investigate the possibilities to improve longevity and stayability of beef cattle with breeding. The breeding goal for beef breeds is to produce animals with high capacity for growth and good feed efficiency. Longevity and sustainability are two important features to include in the breeding goal. If longevity is increased each cow can produce more calves and the number of female calves used for recruitment can be reduced and only the best heifers need to be selected for breeding. The benefits of longer life is that it lowers the costs of recruitment animals, it increases the number of young animals that become available for slaughter, and it increases the proportion of high producing animals in the herds.

The aim of the study is to see how teachers and students work in a multicultural school according to a method which teaches students to write before reading with the aid of computers. A further aim to investigate is how pupils with Swedish as a second language develop their linguistic skills using the method.To participate in modern society requires a lot from the individual. To function in a society that is constantly changing requires a good knowledge of the use of language in order to participate as a democratic citizen. It is therefore important that all students develop good linguistic knowledge regardless of their first language.The study is based on interviews with four teachers, operating in a multicultural school. Besides the interviews observations were made of the teachers and students in their daily work with computers.The results of the study showed that the method is language stimulating and develops the second language of the learners.
