Demokratins förutsättningar i Västafrika : En jämförande studie av Ghana och Guinea
In subsequent to Post-colonialism the African nations have dilated into different political directions. While some nations have established well-functioning democracies, others are still under authoritarian regimes. The aim of this thesis is to examine if civil society has an impact on democratic development in West Africa. Therefore the theoretical starting point is Putnam?s theory of social capital, but this study will also examine other possible causal explanations for democratic transition.This study will be based on a comparative analysis of Ghana and Guinea.
Vi gör vad vi vill men det är inte mycket vi kan göra : Om hur organisatoriska faktorer påverkar mellanchefers möjlighet att arbeta med hållbar utveckling
The group of elderly people in Sweden will increase significantly in the future and science point out that the future elderly people will not accept today?s standards and offers of assistance in today?s public elderly care.

The aim of the report was to increase the knowledge about what middle managers in public elderly care think sustainable development has to embrace, when it comes to quality and personnel administration, in order to meet the needs of the future elderly people.
Omkonstruktion av testrigg för småskalig ångsmotor
The actual project presents the development of a testing rig for a steam engine. A short overviewabout the development of steam engines is presented, until arriving to the development of thepresent engine, which will require to be tested in different ways.The testing rig studied on this project (based on a Lanchester engine) will be used to testdifferent materials and layouts for the group Piston-Cylinder.The engine is a high performance steam power engine, which is going to have a highpower/dimensions ratio, what will lead to require high performance components and materials.An introduction to the testing rig is presented, and the entire design project is done in order toreplace the disappeared documentation of the current testing rig, built on the 1970?s. Also somemodifications done in the original testing rig are presented, as well as some detected problemsand their possible solutions..
IKT verktyg ? befrielse eller belastning? : Elever i behov av särskilt stöd och deras uppfattningar om IKT verktyg i lärandet.
The aim of this study was to describe and analyse the perceptions that ten 12-15 yearold pupils with special educational need, who had been assigned a personal computer, have about Information and Communication Technology (ICT) in the learning process. Data was collected by personal interviews and observations.

Students had various opportunities to succeed in using their tool depending on e.g.
Statlig eller privat vattenförsörjning? : En debattanalys
The purpose of this essay is to illustrate the debate of water politics and privatisation of water distribution. My method is debate analysis and qualitative idea analysis and for my essay I used three books that try to persuade the reader that his or her idea is the best for this water crisis. My main question is to illustrate the debate concerning water privatisations. I will also look at the arguments for or against privatisations and finally determine how the authors think the state should act towards this subject. The first book I used was Vandana Shivas ?Water Wars? that when published started an international discussion about the water privatisations.

Kamratskapets påverkan på barns identitetsskapande i skolan
The purpose of this examination paper is to get an understanding as an upcoming teacher about how friends make an important impact on children?s identity development in school, their choice of friends circle and what kind of groups there can occur among them. With a deeper comprehension of these circumstances should an educationalist be more considerate and adapt his or hers education to prevent negative group formations and to be an outsider. To achieve my results I used a qualitative research method where I through observation handpicked eight students from upper level of compulsory school with different friend circles from two classes for further interviews. Beside this I observed students in their school environment for three days.

Störningsindikation på lågspänningsnät
Föreliggande rapport är avsedd som ett examensarbete i elektroteknik (20p).Syftet med arbetet är att skapa en applikation för att finna störningar pålågspänningsnätet upp till 95kHz. Bakgrunden till arbetet kommer frånenergibolagen som vill kunna skicka datainformation direkt pålågspänningsnätet, detta vill de kunna göra med hastigheter mellan 2k ? 5kHz. Beroende på med vilken hastighet man vill skicka information kan störningar mellan givna frekvenser hindra datatransmissionen, därför är detviktigt att hitta vid vilka frekvenser störningarna uppstår så att lämpligaåtgärder kan vidtas.Grundläggande delar i applikationen är ett oscilloskop för mätning, dator medGPIB- kort för upptagning av data och LabView programvara för hantering avdata. För frekvensanalys kommer Fast Fourier Transform, FFT, att användas,varvid en grundläggande beskrivning kommer att medfölja..
Musik som ett specialpedagogiskt verktyg för barns språkutveckling : Fem sydafrikanska pedagogers syn på musik som pedagogiskt verktyg
The purpose of this essay is to study if and how five South African educators work with music as a special pedagogical tool in children's language development.

They rather use music as an everyday educational tool to promote children's language development. The result indicates that music in educational activities promotes children?s communication with each other.

En resa till företagets medelpunkt : - en studie av kompetens på mellanchefsnivå
The profit a company makes is dependant of its employees which means that their competence is important for the company to perform well. The middle manager has a central position in the organization and is expected to take on different roles. This probably puts a lot of demands on the middle managers and their competence. We want to contribute with a comprehension of how learning, competence and needs for competence can look at a middle management level. Furthermore we also want to find out what kind of strategy for competence development the middle managers want the company to use so their competence development can be facilitated.

The study is also based on Vygotsky's sociocultural perspective which says that all learning takes place through relations and interaction with other people in the cultural context you are in. The results have shown that pre-school teachers are aware of the circle time?s importance to children?s development, and purposely plan the circle time to give children the opportunity to develop both socially and linguistically skills..
