This literature study aims to examine the existence of cancer stem cells in breast cancer. The cancer stem cell theory states that there is a hierarchical organization within a tumour, in which a small subpopulation of the cells can initiate new tumours and maintain tumour growth whilst the bulk of the tumour cannot. These tumour initiating cells have shown to possess many characteristics similar to those of adult stem cells, which is why they are often referred to as cancer stem cells. Both cell types have the capacity of asymmetric division and have shown to possess mechanisms of resistance to both apoptosis and cancer drugs. The cancer stem cell theory elucidates many biological aspects such as the heterogeneity of tumours and the relapse of many cancers after what appeared to be successful treatments.

The purpose of this study is to explore the differences and similarities regarding the causes of and approaches to bullying among a number of girls and boys in third grade in two schools. One of the schools is in a mono-ethnic area and the other in a multi-ethnic.The purpose isto compare the results between the schools and the questions proposed are:What is the reason for the bullying?What are the differences and similarities in existing opinions on the practice of bullying?What are the differences and similarities of students' opinions on bullying in a mono-ethnic and in a multi-ethnic school?I have chosen to use gender and ethnicity theories and the study was conducted through qualitative group interviews. The results have shown that boys' explanations for bullying are more aggressive than girls, although approaches to bullying were more related with violence among boys. The multi-ethnic school uses more direct bullying compared to the mono-ethnic school where indirect bullying occurred more often.

Climate change and the sea level rise that it contributes to is an ever more pressing issue for costal municipalities around the world. Today there is a great deal of scientific reports and projections on what these changes could entail. However, resent studies on south Swedish costal municipalities have shown great discrepancies when it comes to how these scientific projections are implemented in the municipal planning and adaptation strategies. In an effort to understand the underlying reasons for this lack of concurrence, this paper has applied Rolf Lidskogs theory of the hetrogenity of science. The theory gives an explanation to the complications in the science-policy interface, by describing complicating factors in the communication between these actors.

In Jan Jagers and Stefaan Walgrave theory about populism as a political communication-style they claim that one can find this in the rhetoric of political parties. In their study of Belgian politics they found that the extreme-right party Vlaams Block has embraced this populism to a larger extent than other parties. Based on this theory this thesis aims at finding populism as a communication-style in three different Swedish political parties with the purpose to see if the extreme-right party ?The Sweden Democrats? will show populism to a larger extent than other parties, as was the case in the Belgian study.Based on Jagers and Walgraves operational definition of populism as a political communication-style this thesis applies it to the rhetoric of three different parties being ?The Social Democratic Party?, ?The Moderate Party? and ?The Sweden Democrats?. This is done in order to be able to clarify on the one hand if their theory is applicable to the Swedish case and on the other hand to what extent populism as a communication-style exists in Swedish political rhetoric.The method for this thesis has been a qualitative text analysis since and leads to the result that Jagers and Walgraves theory of populism as a communication-style is applicable to the Swedish case and that ?The Sweden Democrats? to a larger extent uses this political communication style, than the two other parties..

För det första konstaterade jag att det är väldigt svårt att mäta produktivitetsförändringar inom IT-området. Trots svårtigheterna att mäta förändringar var det en som uttryckligen lyckats åstadkomma mer under arbetstiden eftersom intranätet medfört att han kunnat byta ut restimmar mot arbetstimmar. Dessutom kom jag fram till att alla respondenter erhåller mer information än vad de behöver till sina respektive arbetsuppgifter. Situationen är mest akut för människor som är ute och reser mycket, och därför inte har en daglig kontakt till intranätet. Många av intranätanvändarna väljer hellre att ta avstånd från intranätet än att riskera att drabbas av för mycket information.Det är inte många av intranätanvändarna som sitter och letar efter information.

Fighting against accidents with elderly involved have come to be one of the west world's greatest challenges together with the climate changes and epidemics, and in order to fight against these accidents SDF Centre, Gothenburg appointed a man to the post as a caretaker.The aim of this master thesis is to analyse whether the implementation process and the systematic work correspond with Vedungs implementation theory and also put forward arguments for and against a masculine entrance into promotion old-age care; if it strengthens or is a take-off from the classical sexual roles.The thesis main theory is Evert Vedungs theory of implementation, which is constituted of eight factors which facilitates an implementation process. In order to theorise the sexual roles I have appropriated a gender perspective, constituted of multiple researchers and authors.The conclusion I have received through the qualitative interviews carried out with actors involved in the implementation process, is that the security services implementation correspond well with Vedungs implementation theory, hence the implementation has proceeded efficiently. The classical sexual roles is on one hand strengthened through a masculine possession of the security service, and on the other hand can the masculine entrance in the old-age care entail that more men apply for promotion old-age care work..

The aim of this study is to illuminate and discuss a case of political steering, specifically Managment-By-Objectives (MBO) in Swedish municipalities, from a democratic perspective. The essay examines a discrepancy between MBO in the Swedish municipalities and democratic theory.To fulfil the aim of the study one leading politician and one leading civil servant from five municipalities have been interviewed on this matter. This material is discussed in the light of a democratic theory constructed specifically for this essay. The democratic theory consists of three main democratic values in the democratic process: debate, transparence and the ability to demand political accountability.The main conclusion is that there is a contradiction in the use of MBO and the democratic values of debate, transparence and the ability to demand political accountability. MBO has resulted in a lack of debate and transparency and furthermore, it has made it increasingly more difficult to demand political accountability..

This examination work aims to describe how a supply chain around the biggest pellets factory in Sweden will be configured in a logistic perspective. The plant and associated infrastructure are in the building phase and will have production start on the 2 November 2009. The key question that is set in this examination work is to recognize the logistic processes which are essential for an effective flow of materials and information that link the source of supply with the ultimate customer. In order to get the answer, a flowcharting of these supply chain processes is required for understanding the pipeline activities such as input and storage of raw material, the production system and the output of pellets to the customers. The basis for this supply chain map is a model-based representation of these logistic processes and activities that are involved around the pellets factory.
