Socialt stöd bidrar till mindre risk för yrkesrelaterad utbrändhet. Var tredje lärare uppvisar inom sina första arbetsår symptom på utbrändhet. Syftet med föreliggande studie var att undersöka samband mellan socialt stöd och utbrändhet hos grundskolelärare. Totalt deltog 71 respondenter i Stockholm via enkäter. Socialt stöd mättes via Berlin Social Support Scale och utbrändhet mättes med Shirom Melamed Burnout Measure.

The ability to tackle NP-hard problems has been greatly extended by the introduction of Metaheuristics (see Blum & Roli (2003)) for a summary of most Metaheuristics, general problem-independent optimisation algorithms extending the hill-climbing local search approach to escape local minima. One of these algorithms is Iterated Local Search (ILS) (Lourenco et al., 2002; Stützle, 1999a, p. 25ff), a recent easy to implement but powerful algorithm with results comparable or superior to other state-of-the-art methods for many combinatorial optimisation problems, among them the Traveling Salesman (TSP) and Quadratic Assignment Problem (QAP). ILS iteratively samples local minima by modifying the current local minimum and restartinga local search porcedure on this modified solution. This thesis will show how ILS can be implemented for MSA.

Uppsatsen behandlar mindre företags införande och användande av elektronisk handel. Utifrån teorier för elektronisk handel har vi sammanställt riktlinjer som tillsammans utgör ett nytt teoretiskt ramverk. Under författandet av uppsatsen har ramverket kontrollerats och delvis förfinats utifrån vår empiriska studie och genomförda analys. Ramverket innefattar mindre företags införande och användande av elektronisk handel. Uppsatsen framhäver riktlinjer angående elektronisk handel som mindre företag bör ta hänsyn till.

When a company is part of an agreement there is a risk that one of the collaborators pursues similar business and takes up competition with the partner or chooses to reveal information about their partner to other parties. To avoid this, companies establish a confidentiality agreement that prohibits the parties to reveal any information. Confidentiality agreements that are eternal have become more common in Swedish contract law in commercial relations. As a result, disputes between collaborators have occurred regarding the unreasonable length and validity of the agreement at a later stage.When a confidentiality agreement is considered to be unreasonable, 36 § of the Swedish contract law (AvtL) can be applicable. The paragraph deals with the legitimacy and the opportunities of re-adjustment of the unreasonable contract.

This report is a study in voltagelevel in connection with regeneration of brake energy from the tramtype M31 in Gothenburg.In the act of braking, the tram M31 uses electrical braking where the electrical motors generates energy and if possible send it back to the overheadline, where other trams in the nearby can use this regenerated energy for its own driving force. In cases where no other energyconsumers are located in the same section, there is a resistance witch task is to convert this energy into heat. The regulation of this resistance appears to cause an increase in the voltagelevel into far too high levels.Investigations of the trams regulationequipment and its construction have been done. Further have measurements on the overheadline been performed in order to map the voltagevariations during a longer period of time.The result have been showing that the voltagelevel during regeneration often is as high as 880V-920V, more extreme values have not been observed in a large scale. The values are especially high compared to the nominal voltagelevel.

The Goal with this Master of Science thesis is to expand the possible turbine efficiencymeasurements on an exhaust turbocharger. It was done as a part of the CICERO competencecentre. To feed the turbine with air a special flow rig has been used. Instead of loading theturbine by just restricting the compressor flow a docking system for an electrical dynamometer isdesigned to use the dynamometer as an additional loading source. By using an electricaldynamometer as loading device for the turbine, measurements are not depending on compressorperformance.A large part of the work consists in designing accessories for the dynamometer.

The intention is to focus on the implementation of the tablet in preschools and how the intentions around the introduction of the tablet take shape in different preschools. The method is semi structured interviews where the respondents consist of 3 preschool directors and 6 teachers where the preschool directors work. This is a relevant subject to illustrate, as the tablet has become a tool in preschool where it seems to be different opinions about how it should be used. This study aims to understand how the implementation can take form in different preschools, what kind of similarities and differences we can see with the intentions of the tablet and if there is need of clarification on the workings of the tablets in preschools. The results show that the intentions around the introduction of the tablet in preschool look different in the preschools, and the implementation of this new technology starts in a small scale with help of photographing and videotaping.
