Översättare eller särskiljare? -elevers syn på att ha elevassistent i grundskolan
In all times school has defined and categorized pupils from a hypothetical normality. The National Agency for Education is today critical to how the municipalities provide for the necessity of special support for pupils with difficulties in school.Pupil`s assistants has been a growing profession in school during the last decade and their importance for the pupils is relatively unexplored. The aim of this study is to find out how the pupils think about having pupil`s assistant during the obligatory school on the basis of the ideas of power, knowledge, involvment and understanding. The study is based on qualitative interviews, consisting of half-structured questions, with eight pupils that have or have had pupil`s assistant during their time in senior compulsory school. The result notifies that the pupils feel powerless in school, they have no opportunity to affect and they do not think they are someone that could make any change.
Folkbibliotekens oberoende? ? En ideologianalys om politisk ideologisk påverkan på folkbiblioteken
The subject this thesis will investigate concerns the matter of how political ideologies exist within public libraries with a focus on the democratic ideal. Public libraries are part of the political system and we want to show how political ideologies take their shape in public libraries and the possible consequences of this. With the help of three major political ideologies, liberalism, conservatism and socialism we investigate how the democratic ideals of these ideologies are expressed in documents that describes activities the libraries will and have performed. In order to identify these ideologies we use discourses in cultural policy as a bridge between the investigated documents and the political ideologies. As an analytical tool we have developed a model that describes the relation between text, discourse and ideology which we use in our analysis.
En ekonomisk utvärdering av framtida biobränslebaserade processkoncept inom energisektorn
The main purpose of this bachelor thesis is to create a product in the form of a database that can be used for cost estimates of equipment within bio refineries. Through interviews and literature searches the key components and their costs were identified. The database was constructed in Microsoft Excel with different tabs for different categories of components; these tabs are further divided into three parts: one part with costs, one part with calculations and an information part. Most of the part with costs contains the expenses found in scientific papers during the literature study, the calculating part converts different capacities according to user preferences and the currency to euro (?) from 2010 and the information part consists of references and information about what is included in the cost.The database is a good tool for making cost estimates for bio refineries.
Maskinskydd på rullriktverk
ESAB is a world leader in production of welding consumables and equipment. The company manufactures, among other things, welding electrodes. A roller straightening unit is used in the cutting process to straighten the wire, which the welding electrode consists of, by adjusting some of the rollers during operation. According to ESAB?s standard and the European machinery directives, moving parts of machinery, such as rollers of the roller straightening unit, must be out of the operator?s reach.
Regressionsmodellering av dynamiska råemissioner från statiska mätningar
By using steady-state measurements for predicting emissions under a dynamic drive cycle wouldsave a lot of time and money for the exhaust aftertreatment specialists at Volvo cars. The idea forthis thesis has been to investigate if statistical regression models can be used with good accuracy.Questions included are for example if common operating variables such as engine speed, air-fuelratio etc. is sufficient to predict engine-out emissions over the engine operating range with goodaccuracy. Focus was set on the modelling of warm engine, but also the more complex engineheat-up phase was investigated since it is a great contributor to total emissions. While NOxcouldnot be measured because of malfunctioning measurement equipment, only HC, CO andtemperature at inlet of first catalytic converter has been modelled.
Site fidelity of a migratory species towards its annual range
Site fidelity, the behaviour of animals to return to areas where they have been before is a common trait in many species. The Scandinavian moose is known to show fidelity to its range, but to what extent, is little known. The landscape in Sweden changes in a predictable and unpredictable way and hence gives the opportunity to test the existence of fidelity. I used the kernel Brownian bridge method to estimate the home ranges of individual moose over consecutive years and estimated the overlap at the home range level. I also used Euclidian distance to look on calving site fidelity.
Batterilyft för telekom basstationer
The purpose with this thesis work was to design and build a technical aid for installingbatteries in telecom base stations. Today that job is done manually, since there is noequipment on the market for that purpose. Installing batteries in base stations manually isa very tough job.To get ideas for possible solutions a preliminary study on existing lift aids was done.From the preliminary study the conclusion that some kind of overhead crane would besuitable for the task was drawn. After that a lift for installing batteries in base stationswas designed, built and tested. The tests show that it is possible to minimize heavy liftingwhen installing batteries in telecom base stations, at a relatively low cost.ii.
Dubbel problematik : socialtjänstens, psykiatrins och beroendevårdens föreställningar om samverkan kring dubbeldiagnostiserade
The essay's aim was to see which attitudes county council's and municipality representatives had about themes like: collaboration and competence in the work around double diagnosed persons. Its objective was to zero in on the attitudes of the representatives regarding a coallocated collaboration project in Stockholm. Also, it sought to find out what attitudes the representatives had about the other representatives attitudes concerning the above mentioned themes. A number of attitudes were presented during the qualitative interviews with the representatives, highlighting which attitudes seemed strongest. Then the interviews were analyzed using meaning condensation and then set against the theory of social representations.The analysis showed that before work with the target group starts, there?s a need for synchronization of the different representatives involved in the collaboration project.
Ökar surfplattor afatikers digitala delaktighet?
In today?s society more and more activities are digitalized. This means that everyone has to be able to use information and communication tools (ICT) in order to take part in the digital world, otherwise they will be left out of the digital community. There is a so called digital gap between for instance elderly and young people, where elderly do not know how to use the tools and there for cannot gain access to the digital society. What happens when people, not only grow old, but also have a communication disorder, such as aphasia? How are they included? The purpose of this study is to investigate whether or not surf pads are good tools for bridging the digital gap for people with aphasia, and which activities and situations that encourages people with aphasia to work with the surf pad.

Jordbearbetningsstrategier på hösten inför vårsådd på tyngre lerjordar :
It is important for today?s farmers to minimize the costs for crop establishment, because
of decreased prices and support from the EU. Farmers, who plow in autumn on heavy
clay soil, often do some kind of tillage in autumn to get better soil structure before
spring seeding. This is especially important when growing small seed crop, e.g. sugar
beet and oil plants.
Skärgårdsliv för rekreation : En undersökning av möjligheterna till vistelse i Stockholms Skärgård
AimThe aim of this study has been survey the possibilities for short-term stays in the Stockholm Archipelago for people without their own means of transport, own equipment and/or experience of outdoor life.To fulfil this aim, the following questions were formulated:? What communications are available to chalet parks in the Stockholm Archipelago?? What overnight accommodation is available in the chalet parks in the Stockholm Archipelago?? What activities can be pursued in the Stockholm Archipelago?? What is the financial cost of travelling to and staying in the Stockholm Archipelago for a week?MethodWe chose to use six interviews and three observations in order to gain as much insight as possible. Interviews were conducted with Claes Petterson at Waxholmsbolaget, a company that provides transport services in the Archipelago, and with managers for five chalet parks: Rolf Andersson for Finnhamn, Per Englund for Grinda, Arne Johansson for Rånö, Pär Hjärtström and Peter Hösöyen for Gålö and Anders Bedinger for Gålö and Nåttarö. The interviews were recorded in writing and on tape. Observations were carried out at three chalet parks, i.e.
