The thesis deals with three document retrieval models based on logic: the Boolean model,the fuzzy model and the Van Rijsbergen model.In Chapter 1, the author presents the purpose of the thesis. This is to give the logical foundationof the models, to describe them and to examine them critically. In Chapter 2, some importantnotions in document retrieval are presented. Chapter 3 is devoted to the Boolean model, Chapter4 to the fuzzy model and Chapter 5 to the Van Rijsbergen model.These three chapters are organized in the same way. First, the logical foundation of the modelis given.

From policy to practice - a study of textile companies view about challenges with implementing CSR policies examine the textile companies awareness of which challenges there are with the implementation of codes of conduct in a global supply chain, as well as to analyze how the companies deal with the challenges. With increased globalization many companies have chosen to outsource entire or parts of the production in various developing and newly industrialized countries. However, the working conditions in these countries do not always fulfill the labor standards that are defined in various conventions. The society began demanding companies to take social responsibility. The social responsibility goes under the term Corporate social responsibility (CSR).

User comments:Availability and Utilization in Online News Affiliated with Local Daily PressAuthor: Susanne AlmgrenSupervisor: Mats EkströmConstituent: Dagspresskollegiet (Annika Bergström/Ingela Wadbring)Course: Term Paper in Media and Communication StudiesTerm: Spring Term 2012Pages/word count: 91 pages / 38 334 wordsObjective: To examine the users availability to the user comment feature and how theusers utilizes the user comment feature in the context of an online news site affiliatedwith local daily press.Method: Mixed methods approach, content analysis and discourse analysisMain result: In this context, three out of four news stories (76.5 percent) has beenallocated with the user comments feature. The highest availability to the user comment feature was found in news themes covering sports and entertainment, followed by financial news. News stories lacking the user comment feature weremainly found in news themes concerning crimes and accidents. The user comment frequencies are not normally distributed along news stories. On the contrary, 62 percent of the news stories did not get any user comments at all.

In cooperate with Asko Cylinda we have developed a new heat system too short the process time and reduce the energy consume in a dishwasher and still have it too be a class AAA. The environment and quality is important for the company too still be the number one on the market, If they want too keep that position the product developed of new innovations will be very important. The systems we have developed are more effective and reduce energy up too 25 %. The process time is reduced too less than two hours, from the today two and half-hour. The solutions are too heat up the rinse water and the dishwater at the same time, with a new heating system and it make are solutions unique and effective. Its good for the dish and the environment.

The purpose of our study was to investigate whether national adoptions could be an option within the childcare system in Sweden. We wanted to create an understanding of how the professionals agree to this. We have implemented a comprehensive literature review as well as a qualitative study, taking benefit of a phenomenological method of analysis. The result of our study shows that national adoptions cannot replace foster placements but be a good addition to foster homes. Adoption gives the children a more secure and stable life..

A substantial part of the Swedish outdoor education is being practiced in so called ?school forests?. The concept school forest was first introduced in the 1980?s by the organization Skogen i Skolan. The definition of a school forest is an area that is being used for educational purposes, over which the school and the land owner has reached an agreement of how the school may utilize it.

AimThe aim of this study is to examine the long term effects of e12 and how they have influenced the lifestyle and perceived awareness about nutrition and exercise in relation to factors from Social Cognitive Theory (SCT) that e12 took in consideration. The questions asked were; How has e12 affected the attitudes, skills, self-efficacy and knowledge relative to exercise? How has e12 influenced the individual?s habits of exercise? How has e12 affected the perceived awareness regarding the impact of nutrition and exercise on the body weight?MethodThe study is pursued by a qualitative method using semi structured interviews on six individuals between the ages of 16-18 years old that completed the project 4-5 years ago. A questionnaire regarding nutrition and exercise habits was also used as part of the study. All individuals from the year of interest were first contacted by the senior physician connected to the project.

In this thesis we calculate the Hawking mass numerically for surfaces in Kerr spacetime. The Hawking mass is a useful tool for proving the Penrose inequality and the result does not contradict the inequality. It also does not contradict the assumption that the Hawking mass should be monotonic for surfaces in Kerr spacetime. The Hawking mass is quasi-local and defined by the spin coefficents of Newman and Penrose, so first we give a discussion about quasi-local quantities and then a short description of the Newman-Penrose formalism..

This report will present athesis on behalf of Eleiko Sports AB and carried out by two students at the InnovationEngineering (University of Halmstad).

A clear structure for participants, stakeholders and information flowbetween these parts will be included in this report so that you can clearly seethe areas of responsibility. The report includes a timetable which the grouphas worked along and also methods used. In the development process you will beable to read about how the students in an interdisciplinary way have used themethods and come up with an entirely new product.

Based on the on the assumption that the two recent Swedish poetry collections mil by Anna Hallberg and mallamerik, mallamer, malameri, mallame, amerik, mallameka, merikka, by Lars Mikael Raattamaa, are constructed with theoretical questions about identity, national identity, language hierarchy and power in mind, this study aims to investigate the ways in which these issues come to expression. Simplified, the term language-poetry, or språkmaterialism, can be used to describe a language-philosophical poetry that aims to eliminate the hierarcic structures between writer and reader in a text and invite the reader to become the co-worker of it. The study shows that by different ways of eliminating the centre of the text, the text is made democratical. But one question that this study asks is how can a nation's conventional and standardised written  language ? the language of the centre ? be used to write itself out of this centre into the margin? Stepping from a theoretical background of postcolonial theories on identity and national identity, including reflections as those given by Benedict Anderson, Madan Sarup, Timothy Brennan, Stefan Helgesson and Mia Cuoto, the analysis points out how this poetry laborates with the terms bugging, repetition, national language identity, and space as poetic material, in order to work in line with ? and contrary to - conceptions of a unified and shared language.

This thesis purpose was to contribute to knowledge which could explain the driving forces behind Corporate Social Responsibility in corporate Sweden and their strategic impact from a management perspective. The method used to archive this research was a qualitative interpretative study conducted by interviews. The thesis is based on descriptive theories of drivers for CSR, concepts of strategy and CSR and normative/instrumental theories suggesting a strategic approach to CSR and stakeholder management. The empirical study is based on interviews with Swedish business managers in a strategic board position as well as consultants working with CSR strategies, supported with internet information from companies? webpage.

Learning words have shown to be a very crucial part of learning a second language and the one most important factor to make pupils with Swedish as a second language succeed in school. To make sure that all pupils get the right conditions to learn from all subjects and their entire content a wide vocabulary is necessary. Even so it is found that there are shortcomings regarding this kind of teaching in Swedish schools.Through interviews and observations of two teachers that teach pupils with Swedish as a second language, and also with a short reading test for the pupils, the possible strategies that these teachers use for learning words have been studied. The result shows that the teachers are using several strategies and that they are actively working with transmitting these to the pupils, but there are some areas that need developing..

Agriculture has to be performed in a sustainable way in order to sustain high yields and to support a globally growing population. Functional soil properties are fundamental for high yields and in order to achieve good soil conditions sustainable management is a key. Loss of soil organic material and increased soil acidity are problems associated with degradation of soils and hence less sustainable agriculture. In this thesis, the effect of different agricultural systems on soil organic matter, pH and yield was examined. The systems examined are a cereal system with straw removal or returning and a ley system, all with different nitrogen levels.

AbstractThe purpose of project is to study the possibility for Borås Energy & Environment to build and run a commercial ethanol production facility in Borås. The project also studies the technology for the production of ethanol using renewable energy, e.g. lignocelluloses with focus on two processes, svag-syra hydrolyse and enzymatic hydrolyse. The technology of the process is based of hydrolysation of biomass (hemicelluloses and cellulose) to sugar and extract it to ethanol. These two techniques will compare with each other to determine which of them that it?s more suitable for ethanol production.

This study investigates the teaching strategies of four teachers, and determines which teaching strategies give better results in mathematics at the middle school level? Result here means the knowledge level of the students. The result has been measured through leave out a mathematical test, which I leave out designed. Teaching strategies have been assessed through interviews with teachers and observations of their lessons.My study shows that to go through the lessons thoroughly in the traditional way, and open discussions with the whole class are best for students achievements.The information available, however, is too limited to draw some general conclusions, but my study can be seen more like a counter-example to the general praxis that is short lectures and individual assessment with one to one communication when teaching mathematics..
