The purpose of this study is to examine the importance of a working laboratory in mathematics education, how it influences students? learning and the confidence the teacher has in the laboratory component. Focus has been placed upon the advantages and disadvantages that could follow in the working method.The method used in this essay is qualitative in order to answer all the questions that arise along the way, and in order to use this method in interviews. The interviews that has taken place has been with five class teachers that are currently teaching at a elementary school between the years of 1-5. The purpose of this study has been answered by using its literature and the qualitative method with the class teachers.The results of the research show that teachers express gratitude towards the method in use for mathematics studies.

This thesis examines the subject of reference interviews and the ways librarians form an opinion of users information needs. Using literature and interviews with three librarians I look at the questions below: - Why and when are reference interviews needed? - What significance do they have? - What ideas exist about the performance of reference interviews? - Are there any differences in librarians views of the questions above compared to views in the literature? Results from literature studies and interviews show that reference interviews can be important when librarians try to find out more about users information needs. However its neither necessary nor possible to analyse all reference questions. Librarians therefore need to determine if a reference interview is needed or not.

Sveriges Radio stores their data in large archives which makes it hard to retrieve specific information. The sheer size of the archives makes retrieving information about a specific event difficult and causes a big problem. To solve this problem a more consistent use of metadata is needed. This resulted in an investigation about metadata and keyword genera-tion.The appointed task was to automatically generate keywords from transcribed radio shows. This included an investigation of which systems and algorithms that can be used to generate keywords, based on previous works.

The aim of this study was to examine ways in which High School Students approach academic writing. Both discursive and critical-analytical levels in 21 PM-texts and 14 investigating literary essays were analyzed through a genre theoretical and sociocultural framework in order to widen the understanding of students? usage of explicit textual and interpersonal markers as well as their techniques of writing abstracts. The results showed that nearly 25 percent of the putative abstracts consisted of sampled and reshaped text sequences. The majority of these were on the other hand results of a creative process in which the students reshaped utterances from different sources.

A numerical simulation case involving space plasma and the evolution of instabilities that generates very fast electrons, i.e. approximately at half of the speed of light, is used as a test bed for scientific visualisation techniques. A visualisation system was developed to provide interactive real-time animation and visualisation of the simulation results. The work focuses on two themes and the integration of them. The first theme is the storage and management of the large data sets produced.

The goal of this master thesis project was to develop computer models of some plausiblepretreatment techniques and to assess the potential benefits/costs of using pretreatment andanaerobic digestion for waste management of organic waste from a system perspective. Forthis purpose a computer program called ORWARE has been used. ORWARE (organic wasteresearch) is a program for making life cycle assessments of waste management. As the mainpart of the project work the ORWARE system has been provided with three new models ofpretreatment techniques. The additions consist of: One model of pretreatment with ultrasound,one model of thermal hydrolysis and one model of a screw press.

As students of graphic design the craft of print is close to our hearts. One of the most essential mediums of the evolution of printing techniques is the poster. In a world where digital mediums are being utilized to a greater degree everyday, our love for the printed poster makes us wonder if the days of the poster are counted.What we did was to take a closer look at the role of the poster in promoting events. We focused on the Stockholm area and did qualitative interviews with three different event promoters. Live Nation which is an international live entertainment promoter, Dramaten which is one of Sweden?s most well respected theaters and Stockholm Live which is a stand up comedy promoter in Stockholm city.From doing this we learned that economics play an important part in defining the role of the poster.

Six different Digital Proofing Systems from three different techniques have been evaluated as totechnique, printing quality, economy and usability. Digital proof from two paper qualities, coatedand uncoated, has been compared with references printed in offset, to see how good they match eachother. Only two Proofing Systems manage to print on reference paper. The other Proofing Systemsuse special paper for digital proof.Measurements and visuell judgement show that the Digital Proofing Systems visualise referencepictures with quite good quality. Proof optimised for coated paper visualise the colours with goodresult.

As a member of the EU, Sweden has, in some cases, transferred the controlling rights to the Union. This means that the rules defined by the EU must be followed in all member countries, including Sweden. The European Agricultural policy constitutes the largest part of the EU's annual budget and is in contrast to many other areas fully funded at EU level. The last decade, many new regulations on chemicals and pesticides have been introduced which brought great changes and a lot of work throughout the Union, including Sweden. Sweden has always had a strict policy on chemicals and has been at the forefront when it comes to sustainable agriculture and environmental management.

An analysis of a specific application of anaerobic wastewater treatment at a pulp and board mill, Stora Enso Skoghall, was carried out. A literature study was done and effluent wastewater from CTMP pulp production was analyzed. The analysis consisted of a broad constituent analysis and an anaerobic treatment trial. Results from these test where used to calculate the treatment effectiveness and resulting energy potential at the mill.The literature study and constituent analysis showed that toxicity of the water to be treated, due to wood extractives and sulphur content, was of concern. Detoxification chemicals targeting these constituents where used in the anaerobic treatment trial.

Middle managers in social care find themselves in a middle position. The middle management position involves demands from several interested parties. The demands affect and generate feelings both within themselves and within others and the middle managers have to deal with them all.The aim of this study was to investigate the social care middle manager?s personal experiences of emotions in work.We have completed interviews with four middle managers who are assigned to carry out social care. When doing the interviews we used an interview guide divided into different interview areas.

The purpose of this thesis is to find out if people have changed the way in which they write since the introduction of the internet. Men and women have been writing books, articles, letters, diaries and different types of literature for centuries. To give the reader some background about the weblog as a literary media, this thesis has a whole chapter on half-public literature that includes the history of letters and diaries. The weblog is a unique way for anyone to be whoever they want, whether it be a man or woman, old or young. The reader has no possible way of knowing if the script is true or not.

A company may use different accounting techniques to adjust accounting information and thereby attract investors. Big Bath Accounting is defined as a strategy used to make changes in the financial statements and reduce the results further when the companies expect negative results. This phenomenon has been observed empirically and occurs when including CEO change and negative results. The aim of this study is to test whether there is another factor affecting Big Bath Accounting, namely remuneration of the CEO. The CEOs should, by changing the accounting information, be able to influence their compensation.

How can we use modern X-ray technology to raise awareness of the information that is hidden in historic upholstery? The materials and techniques add information to the history object in question and  about a profession that is sparsely documented in our country. The knowledge we have today has largely been obtained by studying damaged upholstery, or by removing the show cover and upholstery, a technique which involves high risk of damaging the upholstery. X-ray technology offers  a non- intrusive way to examine historical upholstery.Through case studies, I examined four artefacts. The artefacts went trough an inititial visual exam before being transported to The National Heritage Board in Visby where they underwent a thorough X-ray exam.

The association between social parameters (i.e. socio-economy and level of education) and voting behaviour has been reviewed and analysed based on data from municipal council elections in Stockholm and Gothenburg in 2002. Some social scientists argue that the class voting is in decline and that new social cleavages have emerged. However, by using regression analysis techniques, this study implies a strong dependence of voting behaviour on social parameters, such as socio-economic status (SES) and level of education. Socio-economy appears to be a dominant predictor in the analysis.
