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.

What factors that affect the motivation within the industry are interesting to examine and specifically the factors that are not apparent, in other words informal factors that increases the motivation. The purpose of this thesis is to examine and describe which informal motivator factors co-workers/employees in a production department think are meaningful.

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..

Lund who has over 90 systems in 12 departments and now wants to streamline the management of these IT systems. Governance of IT systems is something that Lund would treat as it carried a large amount of changes in their practices, where the control is something missed in trying to standardize their systems. What's missing for Lund Municipality is routine to fall back on in order to streamline the management when they get into these complex situations.Given that Lund treat so many systems make it so that the situation quickly becomes very complex due of the organization's structure. The municipality is divided into twelve departments that have their own goals, it is an organization that is organized, which makes creating standards become complicated when all departments have different needs. Our study was based on a framework that deals with complex environments that lack a clear definition.An analysis was conducted where we started from the theory associated with the interviews conducted in which we aimed to understand their decision and understand the processes that affect system development.

Web services are now a day often mentioned when speaking of systems communicating with each other online. This master thesis describes how we, with a grounded theory, developed a web service from scratch and then used it to describe how to develop a method for this case scenario. The purpose of the web service is to simplify the information exchange between Infra Gaming, which is the company who assigned this project to us, and their customers. This master thesis is not a guide to how you develop a web service. It is a master thesis that describes how we, in three steps, solved the assignment from Infra Gaming and our problem, with a web service..

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..
