För att veta vad någonting är måste man veta vad det inte är : En studie om hur några elever i årskurs 1 lär sig vad ett tekniskt föremål är
Syftet med denna studie är att undersöka hur några elever i årskurs 1 skapar förståelse för vad en teknisk artefakt är och vidare hur eleverna ges möjlighet till detta genom att läraren använder variationsmönster under ett lektionstillfälle. Materialet har samlats in genom en learning study vilket innebär att vi har genomfört en praxisnära undersökning. Vi har i studien agerat både forskare och lärare; observerat, planerat och bedrivit undervisning samt analyserat empirin. Vi har studerat tre lektionstillfällen i tre olika grupper med fokus på att tillsammans med eleverna skapa en definition av vad en teknisk artefakt är. Med hjälp av för- och eftertester har vi även undersökt elevernas uppfattningar om tekniska artefakter före och efter lektionstillfället.
Musikteori på gymnasiet : En studie om gymnasieelevers inställning till musikteori
The transition from having been under another country?s control to becoming a democratic country can, many times, pose difficulties, which has proven itself to be quite common. Estonia and Moldova?s processes towards a democratic regime are two examples of countries with varied success in the final transition phase.When the USSR (Soviet union) fell and collapsed in 1991 Estonia was well on their way from having a communistic ruling to a democratic one due to the fact that their democratic work had already begun a few years prior to 1991. After the collapse Estonia continued with their democratic work and in 2004 the country became a EU member state.
Skogens produktionsvärden och dess betydelse för Sveriges ekonomi
The forest is characterized by many different values such as those related to forest productivity which are of a big importance for Swedish economy. History has proved that forest resources had helped the country in the transition from the agricultural to the industrial society. Today Swedish forest industry is among the strongest in Europe and significantly contributing to the Swedish export. The industry provides many direct and indirect job opportunities and is one of the biggest employers in the industry sector. It is also worth to notice that the forest can also generate an additional income for the owners, even if the forestry isn?t their primary income source.
Allmänna rättsprincipers framväxt och påverkan inom EU - En uppsats om principerna med fokus på proportionalitet, rätten till försvar och offentlighet
General principles of law can be defined as a legal foundation with the function of codifying basic values. They can also be of a character, which makes them useful as supplement and interpretation of law. EU has developed principles of law that can be divided into general and special. Within the Union there are existences of around twenty general ones. A further separation can be made in terms of institutional and individual.
Graffitifrågan i Sverige - Två städers förhållningssätt
The chosen task in this thesis is to compare two projects of importance on the impact on the approach to graffiti in Norrköping and Göteborg. My main source for empirical findings was interviews. I have examined the Norrköping project Canslit including legal graffiti walls and a graffiti school and the political process around it. This was compared to the Göteborg project kulturprojekt Röda Sten, which is a cultural center that happens to be covered in illegal graffiti. The conclusion was that due to the very detailed plans and well-functioning communications between actors in the Norrköping project, this has resulted in a creative, tolerant approach to graffiti still with low rate of illegal graffiti.
Magnetiska egenskaper hos Öje-Diabasen, Dalecarlia
A study of paleomagnetic remanence and anisotropy of magnetic
susceptibility (AMS) has been performed on the Öje-Diabase
in Dalarna, Sweden, and on basic dikes associated with the
alkaliquartzsyenite/granite Noran-pluton in central Sweden.
Based on isolation of directions of characteristic magnetization
in the basic rocks, a division into three different groups (A,B,C)
has been made. Group Aconsists of dolerites of Jotnian origin,
both dolerites from the Öje-Diabase and dikes associated with
the Noran-pluton are included in this group, making them coeval.
Group B is suspected to show a re-magnetization from the later part
of the Svekonorwegian orogeny. Group C belongs to the
Blekinge-Dalarna-Dolerites (BDD). Thermal demagnetization of
dolerites revealed two different types of demagnetization behaviours,
one where magnetite clearly was the source of the remanence, and an
other with a linear decrease in magnetization intensity. The measurements
of magnetic anisotropy reveals a magnetic fabric with an almost
horizontal foliation and a lineation that indicates a fairly uniform NNW/
S-SE flow direction of the magma..
Olika fönster mot samma omvärld ? En undersökning av omvärldsbevakningen på Stockholms stadsbibliotek och Akademibokhandeln i Stockholm
The aim of this thesis is to explore how a bookstore chain and a public library meet the needs of their customers through environmental scanning. The empirical material is derived from six semi-structured interviews with six informants, three from each organization, together with an analysis of internal documents. The method used is a case study and the theoretical framework is based on models used in the process of environmental scanning, as described by Choo, Hamrefors and Hedin & Sandström among others, and which facilitate a comparison of the environmental scanning of the two organizations. The results of the study indicate that the library, as a public organization with a mission in society, perceives the environment as society as a whole and all its members as their users, whereas the bookstore concentrates on the sectors of the environment that affect their sales. The consequences of these different views are that the library is more active in the environment and uses surveys as a basic source of information, while the bookstore is more passive, and relies on statistics for information.
Kundnöjdhet i revision: En jämförelse mellan företag som reviderats av Big Four och företag som reviderats av någon annan revisionsbyrå
The need for auditing originates from the agency problem that arises due to the separation of ownership and control in companies. The purpose of the audit is to increase credibility of the financial statements that management uses to communicate with owners and other stakeholders. In order for the audit to fulfill its purpose a certain level of quality needs to be obtained. The auditor can also be seen as a provider of a commercial service in which service quality is important. Audit quality can thus be separated into technical quality, which is defined as the probability that the auditor both discovers and reports a breach in the client?s accounting system, and service quality, which relates to the provision of services in general.
Musiken och folkbiblioteket: en studie av musikverksamheten på folkbiblioteken i Borås Stad
The purpose of the master thesis was to reflect and analyze music library activities and policies in the public libraries in the area around the city of Borås, in the south-western part of Sweden. With this thesis I also wanted to look at the interaction between the public libraries, the music school and the music associations in the same area. To investigate these matters, qualitative method was used in the form of interviews with seven librarians from seven different libraries and five representatives of different local music organizations. Other methods used were observations and source studies. The literature used discusses the role of the music department of public libraries as well as that of a music librarian working in a public library.
Osteometriska Mätningar : För artbedömning av får, get och svin utifrån mått av revben
Ribs from sheep, goat and pig are rarely assessed to species due to the fact that they are very similar in their morphology and size. The ribs are instead considered unidentifiable although it is possible to see what kind of bone it is. If these ribs would be identified to species not only would species assessment degree of archaeological source material increase, the relationship between meat-rich and meat poor regions would change.To find out whether there are morphologically measurable differences between sheep, goat and pig ribs, three measurement points on each rib has been defined and measured. At each measurement point two measurements were measured, one medial-lateral measurement and one cranial-caudal measurement. The ratio between the medial- lateral measurement and the cranial-caudal measurement was calculated for each point.
Maktbalansen mellan mannen och kvinnan i Domarboken 19
The thesis of this essay is how literary texts are selected in the teaching of Swedish in upper secondary school, and how teachers reflect upon gender in these selections. To answer the thesis question three methods have been used. Firstly interviews were held with five teachers of Swedish, which have been the primary source for the essay. In addition to the interviews, I have examined two literary anthologies used as teaching aid in the teaching of Swedish and lastly I analyzed the literature and authors that the teachers explicitly express that they use in their tutoring. The secondary sources of this thesis contain research on selections of fictional texts, literary canon and students? re-production of gender.
Rätten till språk : En studie av hur folkbibliotek arbetar med inköp av barnböcker på andra språk än svenska
The purpose of this essay is to examine how public libraries work with children's books, in other languages thanSwedish, regarding acquisitions. The purpose is also to describe what the libraries assignments are in regard tochildren with non-Swedish backgrounds. This is then put in a relation to the libraries democratic assignment.The main questions are: What are the libraries' assignments, as described in the libraries regulations? How do thelibraries work to fulfil their assignments?To answer these questions a survey in two parts has been carried out. The first is a study of the libraries'regulations, and various handbooks that serve as an inspiration for librarians.
Datormodellering av en värmelagrande betongväggs inverkan på det termiska klimatet i ett växthus
This report describes the building of a computer model that makes it possible to simulate the thermal climate in a greenhouse. The computer model is built on the physical theory of heat exchange that occur in a greenhouse, such as radiation and convective heat exchange. The model also includes the heat storage that is active in a greenhouse.The computer model is used to simulate the thermal climate in a greenhouse under three periods, winter, spring and summer. It also investigates which effect a concrete wall has on the thermal climate in a greenhouse. The purpose of putting a concrete wall in the greenhouse model is to investigate the possibility to store heat during the day and then use this heat when the temperature drops during the night.The result from the simulations shows that a concrete wall levels the big difference in temperature that normally occurs under a day in a greenhouse.

Resultat av detta arbete innefattar statistik över kartlagda fabrikers elanvändning samt en rad åtgärdsförslag.
Läsförståelse med stöd av Läsfixarna och Leselos : En jämförelse mellan en svensk och norsk arbetsmodell för ökad läsförståelse
The purpose of this study is to understand how the school manages to question norms, and in doing so might prevent its students from being subjected to discrimination and other degrading treatment. This has been done with a focus on how gender related norms are represented, reproduced and questioned in children?s fictional literature. Two methods have been used; a survey and an literary analysis. The survey was conducted on primary school teachers with the intent to collect information related to their thoughts when choosing books to use in their classrooms, and also to source commonly used fiction.
