1. 21. Förvaltning som verksamhet – bidrag till offentligrättens allmänna läror : Administration as activity: Contributions to the general theory of public law

   Författare :Tormod Otter Johansen; Göteborgs universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; offentlig rätt; allmänna läror; förvaltningsrätt; rättsvetenskap; offentlig förvaltning; rättsteori;

   Sammanfattning : The thesis gives a contribution to the general theory of administrative and public law in order to develop a systematic and conceptual framework for better and more realistic descriptions of public administration. The central claim is that administrative law should take as its starting point the fact that public administration is concrete activity. LÄS MER

3. 22. Injection and Combustion of Alternative Fuels in Spark Ignited Direct Injection Engines

   Författare :Lars Christian Riis Johansen; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; gas fuel; direct injection; E85; stratified combustion; spark ignition; alternative fuels; optical measurements;

   Sammanfattning : Increasingly stringent vehicle emission legislation necessitates increasingly efficient combustion engines. The use of direct injection in spark ignited engines improves engine efficiency and reduces CO2 emissions. LÄS MER

4. 23. Spark Ignition Combustion of Direct Injected Alternative Fuels

5. 24. Om att välja vad och hur : musiklärares samtal om val av undervisningsinnehåll i ensemble på gymnasiets estetiska program

   Författare :Karl Asp; Øivind Varkøy; Geir Johansen; Örebro universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; music education; upper secondary school; choices of teaching content; music teaching; music didactics; discursive psychology; Musikutbildning; musikdidaktik; gymnasieskolan; val av innehåll; musikdidaktik; diskurspsykologi; Musikvetenskap; Musicology;

   Sammanfattning : This study investigates how teachers of the subject ensemble in Swedish upper secondary school talk about their choices of subject content in light of their background as musicians and/or music teachers? According to current regulations and curricula (Läroplan för de frivilliga skolformerna, Lpf 94; Programmål för Estetiska programmet, ES 2000:05) the Swedish upper secondary school system can be described as goal-centered, which implies that the goals of the education are in focus and that methods and material to achieve those goals can show great variances. The aim of this study is to investigate how music teacher talk about their choices of content in relation to several background factors like music teacher education and experience and their experience as professional performers.
