Drinking water is produced from raw water and is either from groundwater or surface water. This thesis aims to find out if the cleaning process of raw water is sufficiently effective. This is important because consumers are otherwise at risk of waterborne infection caused by pathogens. There are three groups of pathogens; bacteria, virus and parasite. These have different characteristics which mean that they require different water treatment to be separated.

This thesis explores some issues regarding estimations of the cost of capital on the Stockholm Stock Exchange through reverse engineering of the Residual Income Valuation model and through usage of the Capital Asset Pricing Model. Previous studies are in conflict of whether the risk premium changes considerably over time or not. Furthermore, the risk premium estimated by CAPM tends to be fairly stable. In this study, reverse engineering of the cost of capital implied by analysts? forecasts shows a significant difference in the risk premium over time.

This paper seeks to investigate whether there is a positive relationship between bonus as a part of total executive compensation and lower accounting quality among Swedish companies. In this study, accounting quality is defined as the degree by which a company's earnings are subject to earnings management. To detect earnings management accrual-based modified Jones model is applied to companies listed on the Large-, Mid- and Small-Cap lists on the Stockholm stock exchange during 2011. We find a statistically significant positive relationship between bonus as a part of total executive compensation and lower accounting quality. Thus, in line with prior research, our results suggest that managers, interested in maximizing their bonus, will select income increasing accruals to manage earnings upwards.

More relevant price comparisons between groceries are possible. This study points outone possible path through an example. The purpose of this approach is to develop amodel in a realistic context.

The aim of this Masters thesis is to investigate the notions and use of non fiction literature of children 9-11 years old. Moreover, this study tries to dissect the underlying concepts that exert influence over the target groups notions and use of non fiction literature. The method and empirical basis of this study is qualitative, with interviews of eight children within the target group. We use a theory of reading exchange to highlight the different areas of usability of non fiction for children. To emphasize how children use non fiction as representative for actual facts, or as non fiction with fictional content, we use a four-field correlation model.

In November 2006 and July 2007, changes were made to the Social Services Law and the Criminal Injuries Law, defining children who have witnessed domestic violence as crime victims. The objective of our study is to examine if these changes have affected how social workers responsible for child protection inquiries interact with children who have witnessed domestic violence, and to what extent these children?s need of support are taken into account. Qualitative interviews have been carried out with five social workers, with the aim to evaluate how they meet and become aware of these children. Our problem-formulation is based upon the question how social services implement the recent changes to the law.

The aim of this thesis is to analyze and examine India's economic reforms which the country introduced on the government's own initiative in the early 1990s after decades of practicing isolationism. The analysis entails a thorough systematic examination of possible factors that determined the decision to implement the reforms. These factors are derived from two models developed by scholars within the field of foreign policy.The research is performed through an examination where the possible factors for the reforms have been examined on a three-level basis; system-, state- and individual level. It is a qualitative case study that seeks to explain not only why the Indian government implemented the reforms but also to evaluate the validity of the models to the extent that they stand in accordance with the case of India.The conclusion presented in this thesis is that one model works better for explaining the case of India. The model lie emphasis on structural changes, a crisis and political entrepreneurs committed to a certain type of reforms as a prerequisite for policy change to take place.

The aim of this bachelor thesis is to examine what expectations young adults have of the public library andthereby determine the relevance of the library guidelines, Påbarns och ungdomars villkor (2003), for young adults. The empirical data is gathered through focus group interviews consisting of 18 participants between the ages of 16 and 17. The conceptual framework for this study is based on Lee´s motivation model for customers in the public library (2007). The model focuses on three conditions for motivation: expectation, instrumentality and valence.The results reveal that young adults in this study have low expectations of the public library. They express little need for public library services because they see the possibility of finding the same things that the library offers through other alternatives, such as the Internet.

The theoretical framework consists of two different models.

This study is based on interviews, document and literature studies. For the analyses we used Torgil Persson?s theoretical model.

In 1984 the Swedish government introduced a special law which gave tax benefits to foreign researchers who for a limited time was engaged in research or development work in Sweden. The purpose was to facilitate for companies to recruit skilled employees from outside of Sweden and to make Sweden more attractive to this important group of researchers and to strengthen the Swedish competitiveness. In 2001 the law for foreign researchers was reformed to include foreign experts, researchers, managers and other key personnel.

There are currently 2160 buildings in Sweden that are protected by law with the designation as a cultural heritage building, which is the strongest protection that can be obtained for a building of cultural historic significance. The purpose of this thesis is to research how strong and sustainable the protection of such a designation is and how you can motivate a revocation. Furthermore, this thesis aims to give an overall insight into all cases where there has been a revocation.To achieve the protection of a designation as a cultural heritage building, the object has to be of outstanding interest on account of its cultural historic value. In the first part, this thesis gives a short historic background of the cultural heritage law and its terms, like outstanding interest and cultural historic value. The County Administrative Board's documents about revocation are the main source for this research.There have been 24 cases of revocation and the frequency of such cases has increased in the past ten years.

The aim of this Master?s thesis is to investigate if the library can be a real partner for researchers in managing and dealing with their research information.

This method focuses mainly on problems and what happens around those problems.
