Eutrophication of lakes and streams are nowadays a well known environmental problem and implies an enrichment of the nutrients phosphorus (P) and nitrogen (N). Phosphorus is considered to be the most important component for the growth of aquatic plants and leads in too large quantities to an intensification of growth. Phosphate (PO4) is the fraction of phosphorus that can easiest be taken up by plants and thus have the greatest impact on eutrophication. Increased plant growth in lakes and unfavorable conditions for aquatic animals are two examples of negative consequences. A significant portion of the increased nutrient supply to nearby water can be derived to phosphate leaching from agricultural areas, where private sewers and agriculture is two main sources.

The main purpose of this Masters thesis was to examine how the Internet and other electronic sources have affected public librarians use of printed reference sources. During the last couple of years the use of the electronic sources - in particular the Internet has become more established in the Swedish public libraries. Our aim was to examine if and how this has affected the use of the printed reference sources. This has been examined on the basis of the following factors: the gender and age of the librarians and how long they have served in the library. We also examined if the size of the library affects the use of the printed and the electronic reference sources and also which factors that are most important when librarians acquire reference sources.

Background: To be better able to meet the new competition, companies are seeking new competitive advantages, wich is forcing them to review and, in time, change both working methods and corporate structures. This has led to an increased interest in the development of strategies within the field of Knowledge Management. Objective: The objective of this thesis is to improve understanding of how learning in a company occurs over internal boundaries and to investigate whether individuals need to be motivated in this regard. We also aim to give recommendations as to how this can be developed. Furthermore, we will work out a model that explains the learning process.

Companies learn through their employees. In this paper I make research into how knowledge transfer and learning occur at Metso Paper Karlstad AB, which is a partly project based organization.The result is that there are many factors that affect the knowledge transfer in a company. Knowledge transfer occurs mainly between individuals within the company, but also between departments and other actors outside the company. In the gaps between these actors, there is a risk that knowledge is not transferred, which is an obstacle to learning. A great deal of the knowledge transfer and the learning is carried out through individual?s own drive and motivation.

AbstractThe aim for this study is to establish how teachers and supervisors at the Child and Recreation Programme interpret the concept ?vocational knowledge?. It is also about how they substantially can see that the pupils are developing vocational knowledge, during their work placement training. The aim of this thesis is to create a base for teachers to work with continuing development in teaching practice. The empirical part of this study is based on interviews. Interviews were analyzed in three categories: definition of vocational knowledge, substantially developing in vocational knowledge and success factors. The result shows that knowing how and knowing why is salient in vocational knowledge.

Background: Sleep-disturbances in persons with Alzheimer´s disease are prevalent. They are characterized as increased frequency and duration of awakenings, decreased slow-wave sleep, REM-sleep and increase of day-time napping. Depression and lower quality of life are associated with sleep-disturbances. Altogether a significant source of stress for caregivers and an important factor in institutionalization. Non-pharmacological treatment alternatives are rare.Method: Single-case A-B-C design, with non-concurrent multiple baselines, a pilotstudy.Aim: To explore if an educational program on sleep, sleep disturbances and behavioural change directed towards caregivers improved sleep, depression and quality of life in persons with Alzheimer´s disease living at home.

In today's producing companies, there is a high demand on early integrated productdevelopment. One way to facilitate communication between departments and collaborationbetween people and thereby enable early sharing of product information within the companyis to use PLM, Product Lifecycle Management.The CAD environment at Scania is at the moment being upgraded from Catia v4 to Catiav5. In this stage it is important that also the interacting computer systems in Scania?s PLMenvironment are adjusted and in the future join the development. Scania has an idea of howthese systems will be developed as the transition from Catia v4 to Catia v5 is being carriedout.

In recent years, the demands for effectiveness and evidence in social work have increased in all work areas, including that of healthcare. This has sparked the discussion on concepts such as practical- and theoretical knowledge and their respective roles in social work. In the light of this, the purpose of this candidate thesis is to investigate healthcare social workers understanding of practical- and theoretical knowledge in the working process as well as their respective influence and importance. This candidate thesis is based on three interviews with social workers from different departments in Norrlands Universitetssjukhus in Umeå, Sweden. To provide range to the thesis, the interviewees were chosen from a purposeful sampling.

Abstract:Title: Engelska (Svenska)Number of pages: 40 (47 including appendix)Author: Carl StrandTutor: Göran SvenssonCourse: Media and Communication Studies CPeriod: Fall 2005University: Division of Media and Communication, Department of Information Science, Uppsala UniversityPurpose/Aim: The purpose of this essay is to analyze how young people, in the ages 18 to 25, relate to the subject of file sharing, and what their attitudes to this phenomenon are. I aim to describe how they use file sharing, their knowledge about it, how their usage have changed due to the new copyright law, what their stands are on the question of resource control and management on the Internet, and what they think of the future of file sharing.Material/Method: The method being used is a qualitative focus group interview model, used to investigate how young people look at the subject of file sharing. The results of the interviews is then applied to a theoretical framework based on thoughts of Denis McQuail, Lawrence Lessig concerning creativity, copyright, resource management and file sharing on the InternetMain Results: My conclusion is that the widespread file sharing habits of young people is not only caused by the temptation of getting free stuff, but of the lack of commercial and legal alternatives. Youths are willing to pay for media if the distribution is superior to the illegal file sharing alternative. They are a generation of young people that has grown up in a society where the tendency in many fields has been to make everything faster and more effective.

This thesis describes the development ofa linear guidance system suited for NORCAN's aluminium profiles. The work took place at LP Innovation, a small technical consulting company, located in Uppsala. The work started with gathering and searching for information. A lot of the information was found in product catalogs, but my supervisor was also a great Source of knowledge, as well as the other engineers at the company. I also had the opportunity to work with the rea lprofiles, to get a feeling and greater understanding how they were supposed to be used. With the use of sketching and CAD, a number of concepts were generated.

The use of marketing research panels are a more and more frequently used source of information for studies within many different branches. The purpose of this report is to investigate the demographic composition of panels and compare it with the population of Sweden, a possible change in behaviour of respondents, and if the source of recruitment is the cause of possible differences in study results. The study was commissioned by Norstats Linkoping office. Sources for the data material include Norstat?s recruitment process and their two main panels with different recruitment sources.

The thesis aims at, from a user perspective, examining how a group of industrial researchers understand the information seeking in their every day work. A qualitative method is employed. The empirical material consists of open-ended interviews with in all ten researchers. All of them work at the Swiss-Swedish Technology Company ABB's research laboratory in Västerås. The thesis is based on the opinion that the scientific knowledge production has become commercialised and that the scientific communication is going through certain changes.

This paper aims to provide a description of how knowledge can occur in Apoteket AB, anorganization that is operating on the Swedish pharmacy market. The purpose of this paper isalso to describe how the organizational learning occurs in the organization, and how theoutcome of this learning can be stored in the organizational memory. This subject is ofinterest since Apoteket AB experience changes in their external environment in that they nolonger have monopoly to sell pharmaceuticals on the Swedish pharmacy market. Earlierresearch claims that organizations need to develop new knowledge in order to take action, andthis development needs to be supported by the management within the organization.The collection of primary data was done by two qualitative interviews with employees withinthe organization of Apoteket AB.Our conclusions are that knowledge can occur in many forms, such as tacit and explicitknowledge. The vast majority of the knowledge within the organization is the information thatcan be found in the electronic database Aponet within Apoteket AB, and that is useful for theemployees in their daily work, and therefore is known as explicit knowledge.

AbstractThe aim is to find out the teachers´ different point of views regarding what and why it´s important to teach children about the human body and in what way educationists can teach this knowledge. Seven teachers are asked, through qualitative interviews, about their point of views on teaching the human body in pre-school.The teachers don`t seem to reflect upon the subject, which shows that a development of knowledge needs within the area.Fist of all the children´s spontaneous questions direct what the educationists talk about with the children. The most frequently mentioned questions are about the circulation of the blood and the digestion organs. The teachers think it´s important that the children get knowledge about the human body in order to get a better opinion of their own bodies and themselves. It´s also important because this is the basis of other kind of knowledge, for instance the knowledge about animals..
