Causes of teachers’ turnover intentions in Swedish schools : A qualitative research

Purpose – The purpose of this paper is to explore the causes of teachers' turnover intentions in selected Swedish schools. Research methodology – This research took the form of a qualitative research. Semi-structured interviews were used to explore the causes of teachers' turnover intentions within the schools selected for this study. The sample was composed by 9 teachers that work in Säter. In order to provide a different yet meaningful perspective, a further interview with the Säter school department has been conducted. Results – Several of the results were coherent with the literature: elements such as motivations to teach, administrative support, workload, class size and collaboration were found to be related to teachers’ turnover intentions and therefore confirmed the previous studies. However, factors like salary, mentoring, autonomy, physical conditions and orderly environment were not found to have a connection with the respondents’ turnover intentions, hence constituting a result that did not confirm the literature. Originality – This thesis extended the previous research related to the causes of teachers’ turnover intentions by focusing on Sweden, which had not been investigated yet to that matter. The Swedish context appears particularly worth researching because of both the particularity of its decentralized educational system and the widespread turnover intentions of teachers.

Student satisfaction in tourism education : The case of Dalarna University, Borlänge, Sweden

The students' expectations must be met to ensure their overall satisfaction. Because of this student satisfaction has become a measurement tool with which the universities can compete against each other in order to attract potential students and also a higher level of internal and external funding. This thesis deals with students' overall satisfaction in tourism education at Dalarna University in Sweden. It is important to understand what it takes for the universities to be able to produce a motivated workforce for the communities and how satisfied students could help in achieving this goal. Sweden was selected because of the recent introduction of tuition fees, in 2010, which has made it even more crucial to understand the factors affecting students' satisfaction. The method chosen for conducting this study was a questionnaire where the students of Dalarna University were asked to rate different aspects of their overall experience on a Likert scale. The research was conducted via Facebook and email questionnaire. The results show different levels of satisfaction based on the tourism programmes and gender for example. The major finding from this research implicate that the social conditions and surrounding city categories are the most influential when it comes to the overall satisfaction of students at Dalarna University. The results give the university and the city of Borlänge an insight on issues that really matter to the students and how to improve them.

The Evolution of a Responsibility to Protect in Africa : The African Unions Emerging Peace and Security Regime

The thesis focuses on, and tries to evaluate, the role that the African Union (AU) plays in protecting the peace and security on the African continent. The thesis takes an interdisciplinary approach to the topic by both utilizing international relations and international law theories. The two disciplines are combined in an attempt to understand the evolution of the AU’s commitment to the pragmatist doctrine: responsibility to protect (R2P). The AU charter is considered to be the first international law document to cover R2P as it allows the AU to interfere in the internal affairs of its member states. The R2P doctrine was evolved around the notion of a need to arrive at a consensus in regard to the right to intervene in the face of humanitarian emergencies. A part of the post-Cold War shift in UN behaviour has been to support local solutions to local problems. Hereby the UN acts in collaboration with regional organizations, such as the AU, to achieve the shared aspirations to maintain international peace and security without getting directly involved on the ground. The R2P takes a more holistic and long-term approach to interventions by including an awareness of the need to address the root causes of the crisis in order to prevent future resurrections of conflicts. The doctrine also acknowledges the responsibility of the international community and the intervening parties to actively participate in the rebuilding of the post-conflict state. This requires sustained and well planned support to ensure the development of a stable society.While the AU is committed to implementing R2P, many of the AU’s members are struggling, both ideologically and practically, to uphold the foundations on which legitimate intervention rests, such as the protection of human rights and good governance. The fact that many members are also among the poorest countries in the world adds to the challenges facing the AU. A lack of human and material resources leads to a situation where few countries are willing, or able, to support a long-term commitment to humanitarian interventions. Bad planning and unclear mandates also limit the effectiveness of the interventions. This leaves the AU strongly dependent on regional powerbrokers such as Nigeria and South Africa, which in itself creates new problems in regard to the motivations behind interventions. The current AU charter does not provide sufficient checks and balances to ensure that national interests are not furthered through humanitarian interventions. The lack of resources within the AU also generates worries over what pressure foreign nations and other international actors apply through donor funding. It is impossible for the principle of “local solutions for local problems? to gain ground while this donor conditionality exists.The future of the AU peace and security regime is not established since it still is a work in progress. The direction that these developments will take depends on a wide verity of factors, many of which are beyond the immediate control of the AU.

A study of slag corrosion of oxides and oxide-carbon refractories during steel refining

The use of ceramic material as refractories in the manufacturing industry is a common practice worldwide. During usage, for example in the production of steel, these materials do experience severe working conditions including high temperatures, low pressures and corrosive environments. This results in lowered service lives and high consumptions of these materials. This, in turn, affects the productivity of the whole steel plant and thereby the cost. In order to investigate how the service life can be improved, studies have been carried out for refractories used in the inner lining of the steel ladles. More specifically, from the slag zone, where the corrosion is most severe. By combining thermodynamic simulations, plant trails and post-mortem studies of the refractories after service, vital information about the behaviour of the slagline refractories during steel refining and the causes of the accelerated wear in this ladle area has been achieved. The results from these studies show that the wear of the slagline refractories of the ladle is initiated at the preheating station, through reduction-oxidation reactions. The degree of the decarburization process is mostly dependent on the preheating fuel or the environment. For refractories without antioxidants, refractory decarburization is slower when coal gas is used in ladle preheating than when a mixture of oil and air is used. In addition, ladle preheating of the refractories without antioxidants leads to direct wear of the slagline refractories. This is due to the total loss of the matrix strength, which results in a sand-like product. Thermal chemical changes that take place in the slagline refractories are due to the MgO-C reaction as well as the formation of liquid phases from impurity oxides. In addition, the decrease in the system pressure during steel refining makes the MgO-C reaction take place at the steel refining temperatures. This reduces the refractory’s resistance to corrosion. This is a serious problem for both the magnesia-carbon and dolomite-carbon refractories. The studies of the reactions between the slagline refractories and the different slag compositions showed that slags rich in iron oxide lead mostly to the oxidation of carbon/graphite in the carbon-containing refractories. This leads to an increased porosity and wettability and therefore an enhanced penetration of slag into the refractory structure. If the slag contains high contents of alumina and or silica (such as the steel refining slag), reactions between the slag components and the dolomite-carbon refractory are promoted. This leads to the formation of low-temperature melting phases such as calcium-aluminates and silicates. The state of these reaction products during steel refining leads to an accelerated wear of the dolomite-carbon refractory. The main products of the reactions between the magnesia-carbon refractory and the steel refining slag are MgAl2O4 spinels, and calcium-aluminates, and silicates. Due to the good refractory properties of MgAl2O4 spinels, the slag corrosion resistance of the magnesiacarbon refractory is promoted.
