Direct effects of the insecticide deltamethrin on zooplankton and benthic invertebrates werestudied during an attempt to eradicate signal crayfish. In accordance with earlier studies theresults of this investigation showed that deltamethrin is highly toxic for arthropods, whileRotifera, Oligochaeta and Mollusca have a higher tolerance. This study concludes thatRotifera in treated ponds coped with the actual concentration of deltamethrin used during theeradication attempt but that they probably got a different abundance and changed compositiondue to a new situation in competition and predation. Crustacean zooplankton totallydisappeared, but approximately a month after the treatment they began to recolonise. All thetaxonomical groups of arthropods drastically decreased in abundance, with total eliminationof the most sensitive groups.

The aim of this two years master thesis in Library and information science is to study the foundation Centrum för lättläst and its work regarding information use with focus on information structures and information needs. The aim is also to examine how Centrum för lättläst cooperate with Swedish libraries to promote the work concerning people with reading disabilities. This master thesis applies a domain analytic theory and method inspired by Birger Hjørland. The domain analysis is confined to examine ontology, epistemology, sociology, empirical user studies, document and genre studies and studies of structures and institutions in scientific communication. The main source material consists of information from the homepage of Centrum för lättläst.

During the last decades the evolution of information technology and the increasing ability to access information have been discussed in many ways. In the beginning the focus was on the technology but now the discussion is more and more about the use of information and how to develop knowledge out of it. There is an ongoing discussion about the difference between knowledge and information. The subject of this Master s thesis is to find out if and how the Swedish elementary school has written into its mission statements to help the pupils to become information literate. For this purpose I have examined literature about information literacy and pedagogic as well as legislation and other documents that control how the Swedish elementary schools work.

The thesis examines ?intermediality? in Svenska Bios (Swedish Biograph) first fiction films. Värmlänningarne (1910), Fänrik Ståls Sägner (1910), Bröllopet på Ulfåsa (1910), Regina von Emmeritz och Konung Gustaf II Adolf (1910), Amuletten (1910), Emigranten (1910) and Järnbäraren (1911) are analysed in relation to theatre, literature, music and ?reality?.

 The aim of this essay was to examine the way preschool teachers and children converse during school meals, and also the way preschool teachers start and develop conversations during meals. The conversations were analyzed from the topic of conversation and the teachers' ways of using language acts such as questions, remarks, exhortations. The study was based on observations, tape recording and contact schedule. The result shows that the topic of conversation is significant for how involved teachers are in conversations during meals. The result also shows how conversations develop or end depending on what language acts teachers use.

This is a study on the outcome of the Swedish Forest Agency´s mission to provide individual advice to private land owners about precommercial thinning. The study was conducted in Sala municipality and included forest owners that had received private individual advice from a Swedish Forest Agency consultant as well as forest owners that had not received individual advice. One of the central issues was to make comparisons between these two groups. The survey was carried out by telephone interviews combined with a smaller field study. The questions were designed to provide information about to what degree the forest owners had been affected by the advice and if there had been a change in the way in which precommercial thinning was performed. In terms of the amount of precommercial thinning that had been carried out, no statistically significant differences were found between the two groups.

We investigated a retirement home, where we looked at whether there are differences, disagreements or conflicts between teams who work day and night shifts. Our purpose was to examine the Heads of Unit and the employees perspectives on their perceived work situation, cooperation difficulties and why they emerged. We chose the general systems theory as our theoretical basis, which gave us the opportunity to highlight different parts that can affect the working climate and the cooperation of the working groups. The study also highlights the importance of structure, common goals, reporting and dialogue meetings. To understand the perceived work situation, we used methodological triangulation, using quantitative and qualitative methods (surveys, semi-structured interviews).

Laboratory work is a big part of chemistry education in high school. During our student training placement we have noticed that the laboratory work is not fully utilized to develop students´ chemistry knowledge. This problem made us want to investigate how the laboratory work in chemistry could be set, to become more meaningful for students. We introduced two preparation methods, and examined the outcome of students learning experiences and their acquisition of chemistry knowledge. This was examined both through surveys and observation.

The purpose of this essay is to explore how students in secondary school seek out and use information. More specifically, the essay examines how the search and use of information differs between students working in groups and students working independently. The essay draws on in-depth interviews with six students. Two different theories are used to analyse the transcripts from the interviews. The first theory consists of Carol Kuhlthau?s six different stages showing how the students? feelings, emotions and actions change during the information seeking process.

The ambition of this study is to examine the discussion surrounding the Swedish participation in the European security- and defence policy. By forming feasible areas of arguments the goal is to gain further comprehension in the case of Sweden. These arguments are formed in close relation to the empirical sources; With less public funding there are economic aspects of cooperation, this could also be related to Swedish the industry of defence systems; A high level of participation in the UN is a tradition in Swedish foreign policy, the European battle groups are the perfect tool to further strengthen the UN ability in conflict management and peace keeping missions; Outside the EMU Sweden could face the political margin, to retain influence a high level of activity ought to occur in the integration process; Finally, the future position of United States and NATO is not clear, Europe needs an capacity apart the US to contribute to lasting peace and stability.

This degree project has been performed with Mega Teknik AB in Landskrona. The project has resulted in a workplace for the cable installers of Mega Teknik. The workplace contains a workbench and a cart.The first stage in this project was to make an analysis of the current workplace to identify the needs the installers had.The different principle construction proposals of how the workbench would look like and which functions it would have was made during brainstorming, in groups and alone. These proposals were compared against each other using a functional analysis that has been put up to get the principle construction that fulfilled most points in this analysis.The proposal chose for further work was a cart and a bench with a module intends, the table got a formulation that creates a better reach for the installers.This proposal was generated in Catia V5 to get a better overview of the suggested proposal.During the primary structure phase drawings over all the products were made and the components were chosen. Calculations were made and the product got the dimension required.

The aim of this thesis is to examine librarians' view on the knowledge and competence required at a small public library and how they look upon their education in retrospect. Library education in the 1970's and 1980's was mainly practical, a vocational training, but since 1995 the education results in an academic degree in Library & Information Science. Due to this, we focus on the ongoing generation shift in Swedish libraries as an aspect of knowledge and education. The empirical study is based on interviews with librarians working in minor public libraries. The informants form two groups, based on their education; ?old? ones and ?new? ones.

The purpose of this report is to investigate teachers views of whether pupils with Asperger Syndrome, autistic symptoms or ADHD shall go in ordinary classes or special groups. The study tells you about what difficulties these pupils often have, what adjustments they need in their schoolsituation and the positive and negative effects of joining a special group.A teacher for special needs, two teachers in special groups and two teachers in ordinary classes have been intervjued and earlier made researches have been studied.The conclusions of this study are that the decision of whether a pupil shall go in a normal class or a special group must be made individually. Most pupils who are capable to profit from the training in a normal class and pass their examination, shall go in a normal class. The greater part of the recommended adjustments are possible to do in a normal class. But it requires more resourses and teachers with better knowledges about theese handicaps..

This paper is finishing part of the two-year master programme in Industrial Engineering and Management.Initially there was an inquiry of studying the queue-times that Fläkt Woods uses when they break down internal working orders. These times were assumed to be too generalised and does not apply to the actual value of the queue-times which generates incorrect data and delivery delays. During the work of this paper it has been established that it is not the queue-times that is the biggest problem. The problem is the shop floor control and the lack of manufacturing the right products at the right time. Therefore an analysis of the production planning process was made to bring forward the real problems.
