Aquaponics is a food production system consisting of a consecutive cultivation of plants and aquatic animals, fish or shellfish, in recirculating water. The plants feed on the nutritious effluents from the fish tank and bacteria converts ammonia from the fish tank into nitrate that is absorbed by the plants. The plants receive nutrition and the fish gain purified water. The environmental impact of the production of fish meal and fish oil used in conventional fish feed includes a large consumption of fossil fuels with subsequent carbon dioxide emission. The aquaponic system can be made environmentally sustainable and self-supporting if supplemented with a vermicompost/vermiculture for the production of worm protein as a fish feed. Vegetable waste from the hydroponic part of the system can be reused as worm feed in the compost and the protein rich worms can be harvested, dried and grinded and brought back to the aquaculture as fish feed. As a first step in this direction, I have investigated the effect of recycling of vegetable waste in vermicomposts on the growth and number of earthworms (this was evaluated after harvesting). The hypotheses were that earthworms can be cultivated in the vegetable waste and that by adding manure to the vermicompost it is possible to obtain a nutrient content adequate to support a continuous worm harvest, in other words create a vermiculture. Eisenia fetida and Dendrobaena veneta were grown in 20 L bins containing peat mixed with either poultry or cattle manure. The proportions were 70% peat and 30 % manure. Discarded plant parts from lettuce cultivation was added to the vermicomposts (35 g per week) and water was supplied with 0.8 L per week.

Construction companies in Sweden have for recent years seen an increase in the numbers ofwarranty complaints associated with the market of resident buildings and the cost for this hasbeen measured to over 1.2 billion SEK per year. Working with poor quality cost as a way ofcreating insight about defects within the company?s processes is a method developed and usedby the manufacturing industry for decades, but have not yet reached the construction industry.This study has been performed in collaboration with a Swedish construction company, wherethe author has been stationed at the aftersales division for residential buildings. Owing tocircumstances, this published report has been made anonymous regarding the company whowill further on be namedthe Company. The Company is aware that warranty claims producegreat costs and has requested a way of putting cost and cause to specific claims in order ofreceiving a more specific cost view and to make the reuse of knowledge more efficient.

The purpose of this paper is to examine the effect that price has on quality expectations and customer satisfaction and how price fits into a customer satisfaction model. An experiment in which participants are subject to scenarios of a high or low quality flight are used to test the hypotheses. The analysis shows that perceived quality has a bigger impact on satisfaction than price. Furthermore, price and quality do not affect customer satisfaction independently of each other. The importance of value compared to quality changes whether the actor is a high or low price actor.

The purpose of this study is to examine what characterizes brand identity and positioning regarding festivals on the current Swedish festival market. In relation to our purpose we are also going to analyze how festival attendees relate to a festivals brand identity. Our research question is as follows:What characterizes festivals brand identity and positioning on the current Swedish festival market?This study has been written with a qualitative research method and an inductive approach. Our empirical foundation is built on a rich content based on personal interviews.

This study is on how small companies can use the Internet as a part of their marketing strategy to gain a leverage on their competitors with small means to survive and expand in the global market. Many Swedish small companies still don?t have a sufficient knowledge on how to use the communication channel despite the various advantages the Internet offers.Case studies were conducted of how AdLibris, A-lotterierna AB and SF-bokhandeln perceived the importance of using the Internet as a part of their communications strategy.This new communication channel demand new ways of applying traditional marketing principals. Careful analysis of the interviews and how the answers relate to new and old marketing theories makes the bulk of this study. The conclusion is that the Internet solely is not enough, a combination with traditional marketing tools is the way to succeed in their marketing efforts.

The purpose of this thesis is to examine why graduates in librarian- and information science are employed by private companies. An initial explanation could be the influence of information technology and its impact on the librarian. A second factor relates to how employers regard the librarian outside the confines of the traditional labour market. The study is primarily based upon qualitative interviews with representatives of Swedish companies who have employed librarians since 1993, the year that the education achieved third level academic recognition. Theoretically we relied upon Manuel Castells discussion on the rise of the information society and its influence on companies and the labour market.

AbstractA Problem to Every SolutionThe Corrymeela Community, René Girard and the ambiguous pluralismThe main purpose of this study is to examine how Girard´s ideas of society, culture andreligion have become part of the reflexion in the praxis of Corrymeela Community through the work of Roel Kaptein and how this praxis can shed light over the work with dissonances of faith and values in education in RE, Social Studies and other subjects.In earlier publications I have studied how dissonances of faith and values can beunderstood in educational settings and in connection with issues of interreligious dialogue.The extensive discussion of how differences in culture, religion and value in a pluralisticsociety are to be analysed and treated in pedagogical reflexion seems to increasingly occupyactors in different parts of the educational system. It is obvious that these issues also arebrought into focus as an important field of research. My main interest in this paper is to study how a reconciliation group in the middle of the conflict in Northern Ireland has developed a view of conflict reason and conflict resolution under the influence of the French researcher René Girard and what aspects of this study that can improve the reflection over pluralism and dissonances of faith and values in everyday praxis in education.For a period of more than a decade I have been in contact with actors in the peace process inNorthern Ireland in connection to different educational projects. The attempts to analyse the different aspects of ?The Troubles? and the efforts to find ways out of conflicts and civil war are many and the literature on subjects related to these tragic history of social, cultural and religious conflicts is difficult to survey.

The mental health has during the recent years decreased among Swedish adolescents while theinternet has become a common tool for communication between people. Aim: The overall aim is toidentify the relationship between internet use among adolescents and their mental health. Method:A literature based study within a defined research field. Result: The scientific hypotheses whichexist is based on whether social capital increase or decrease due to internet use. The healthoutcome is positively affected by internet communication, especially for boys and socially anxiousadolescents.

The study - Hur skapas en journalist? - examines why so many people choose to turn tothe journalist profession when the conditions for a secure position on the labor market ispoor. The study also highlights how recently graduated journalist perceives their temporary and insecure position on the labor market.The study was performed trough ten biographical interviews with recently graduated journalists. Via the interviews I examined what has formed the individuals to perceive journalism as a rational or pragmatic choice for a career. The study shows that journalists, who come from families with high cultural capital, have been shaped by a particular culture of education, which focuses on education as a step towards selfrealization.

Problem: The authors have, during the process of development of this thesis, tried to create an understanding of how a number of organizations, all working with different approaches around the ?brand Sweden?, perceive the efficiency and benefits of using extended concept around embassies as a tool in their strategic work. The embassies in question have an evolved concept in the sense that they don not only hold a traditional political and legal role. The problem facing us authors was the issue whether theses embassies are efficient arenas to coordinate the forces and resources of the organizations concerned, in the mission to enhance the visibility and awareness of Sweden abroad.Purpose: The purpose is to describe the strategic work with marketing Sweden to be able to look in to whether the evolved concept behind the embassies in question are used as a tool in within the work of the organizations. We wish to research this to be able to evaluate if this arena is perceived as efficient for the organizations concerned.Method: In order to get a background to which one establish and communicate a nations brand the authors have studied literature within the subject.

In this thesis we study the development of post-earnings announcement drift (PEAD) in the Swedish equity market from 2000 to 2009. By forming portfolios based on the stock price reaction to quarterly reporting we show that the characteristics of PEAD have changed. We demonstrate that negatively surprising companies show a positive drift during a holding period of six months sufficiently large to render the trading strategy unprofitable. This development holds from 2005 and onwards and these results contradict many a study which finds the same portfolio construction to be indeed profitable. We argue that this development is a trend that will not only affect our study but future studies as well..

We have different kinds of signal processing everywhere around us in our everyday life, in our cellphones, when we are listening to music, watching TV etc. This makes signal processing a very interesting and important technical area, where the demand of skilled engineers sets the limit of what is possible.Working with signal processing requires in-depth knowledge in areas such as mathematics, physics, electronics, and other related areas. For this, it has traditionally been demanded by a talented developer to also master the advanced programming languages such as C / C + + and Assembler.This has begun to change; today there are several companies that offer graphical development environments for signal processing, environments where programming skills are not needed anymore, and the focus can be on signal processing instead.The goal with this project is to build a corresponding graphical development environment to reach an understanding of what is required of these systems, and also to grasp what opportunities that are available within graphic programming. Inspiration for the work has partly arise from some of the tools available on the market, and partly from previous theses that have been written about graphic programming.The challenge lies in creating a program that can execute signal diagrams in real time from given signal blocks, and be able to handle feedback loops in an efficient way and to do so at the lowest "cost" in terms of clock cycles as possible. This should also be compared against to code, compile and run a complete signal diagram directly.To increase the usability it should also be possibility to externally manage in real time the parameters of the signal diagram during execution.The interface is a separate program, which is to some extent similar to Matlab Simulink, where a signal diagram is drawn up graphically by connecting wires between different signal blocks.

Syfte: Undersökningens syftet är att mäta huruvida det går att få ut en överavkastning av aktier som väljs in i (respektive ut ur) OMX Stockholm Benchmark (OMXSB), som följd av att ett index ändrar sin komposition. Delsyftet är att undersöka om det går att se en signifikant ökning av handelsvolymen i anslutning till ändringsdagen.Metod: Studien tillämpar en eventstudie som undersökningsmetod av kvantitativ karaktär. Studien undersöker indexet OMXSB och innefattade totalt 111 stycken ingående och utgående aktier fördelat på 10 tillfällen. Två eventfönster har konstruerats; ett kring annonseringsdagen och ett kring ändringsdagen. Den procentuella handelsvolymen har mätts över eventfönstret kring ändringsdagen.Resultat: Den genomsnittliga kumulerade överavkastningen för eventfönstret vid annonseringsdagen uppgick till 1,02 % (-6 %) för de aktier som valdes in (ut).

In a dynamic and unpredictable reality, either rigid structures or silo architectures areappropriate ways to organize an agile organization. This thesis enlightens these relationsbetween Service Oriented Architecture (SOA) and an organization who acts in a varied andconstantly changing business environment. In other words, this thesis enlightens the question:?How suitable is SOA to organize the enterprise who will meet a constantly changing andheterogenic business environment?.The thesis presents a model where an efficient organization must be agile to be able to actquickly in the business environments with constantly changing desires, needs, expectations,desires etc. According to the same model a Service Oriented Architecture organizes theenterprise elements such as processes, resources, competences, responsibilities, informationsystems etc.

This examination work is about an marketing investigation of John Deere Moco 730/735 during the season year 2003. Moco 730 has an workingwidth on 3 m, and 735 has one with 3,5 m. The research results of 16 moco 730/735 are from intervju- and questionnaire made of the owners. The results also comes from intervju anwser from dealers which sold this mocos. The examination work shows comments and opinions from the customer after one seasons use. In the end of my examination work are all comments and opinions put together in a marketing analysis called swot-analys in Swedish. The analysis declare that the moco 730/735 is functional and have god quality. The future seems god for this kind of moco. The strength for this moco are god quality and the dealers god service support. The most important weakness about this moco are that the machine came out late on the market, compared to other mocos on the market. I think it´s important the have in mind that the customers are very John Deere faithful and this JD 730/735 is used for only one season..
