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 has been to examine what it is in the situation that affects which leadership that is applied on the members of the organization. Our questions that we have explored were; What is it in the situation that influences the leadership applied on an individual or staff group? What similarities and differences have emerged by Hersey and Blanchards situational leadership model?Further, we used qualitative semi-structured interviews at the interview procedures with three managers and three employees. Hersey and Blanchards situational leadership model and Goffmans theory in the book "The presentation of self in everyday life" have been used as a foundation and inspiration in this study.We have found that circumstances like the size of the staff group along with the organizations financials and the resources affect the leadership behavior and how well it is matched with the employees. The function of the leaders position in the context, and the purpose of the situation influences how the leadership is formed.

AbstractThis report was undertaken at the request of the Management and maintenancedepartment of Swedish National Road Authority (Vägverket Region Sydöst) inJönköping.In 1992, the management and maintenance of Swedish roads were laid out onexternal contractors. When putting out a tender for the work, the foundation isfrom a national set of rules which are in constant change. This report is limited towinter road upkeep.The trend in the invitation for tenders is that it is moving from the moreconventional executional demands towards the less controlling demands. Thedownside of functional, less controlling demands is that it is difficult to articulatehow to measure them. The order authority therefore has to find ways to makesure to get what has been paid for.In connection to the invitation for tender of winter road upkeep for 2005, the newset of rules, ATB Vinter 2003 was deployed.The main purpose of this thesis is to see which the big changes in the set of rulesare and how these changes affect the organisation and activities of the contractor.It is also studied how the changes in execution is perceived by road users and howit affects the possibilities of the contractor to come as a newcomer to a new areaof administration.Interviews and examination of sets of rules has led to a list of a number ofchanges that the contractors feel affect their work in any sense.Views from road users that have come in to the order authority have beenscrutinized to see how they have experienced the change.

Parents today can be very stressed at the drop off and pick up of their children, this leads to that they sometimes miss important information that is pinned to the walls for example. Papers has the ability to disappear, a blog collects all in one place. Today, almost everything is digitized.This study has examined what a blog is and how schools and preschools can use it. The blog is used as a communication site for the preschools and school. This exam graduate work is made of three blog analysis, the analysis is made to see if the blogs can help the preschool and school to communicate wiht the parents.The theory I have decided to use in this study is the sociocultural theory.

Aim: The aim of this study is to understand why people have changed their preferred community over time. What are the main factors when changing to a new one?Method/material: The method has consisted of personal interviews with six different people in the ages between 20-22 and of different gender. The main material that has been used in this essay is the theory of Uses and Gratifications as explained by Denis McQuail, the theory of Convergence culture by Henry Jenkins and the theory about Communites of Practice by Etienne Wenger.Main results: This study shows a heavy affection that the use of communities often centers round the people around the community, rather than the functions that the communities themselves provides. Having people that you know on the community you choose is a vital part for people or at least having the support of other people and changing to another community at the same time.

The first information recruiters have access to, when recruiting a new co-worker is the applicant´s CV. It may even happen that the applicants are sending a photo with the CV, which can lead to the possibility that the appearance of the applicant will affect the assessment. Previous research shows that individuals who are regarded as beautiful get a better assessment than those who are considered to be ugly or mediocre looking, but if this can be prevented through awareness, the problem can easily be counteracted. The purpose of this thesis is to, through an experimental study, investigate whether recruiters can avoid being affected by the applicant?s appearance in the assessment of their CV if they receive information about the stereotypical thinking that is tied to a person's appearance.

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..

The aim of this thesis is to study the reading habits of Swedish librarians visualized by librarians from Götabiblioteken ? a collaboration of 14 public libraries in mid-Sweden ? focusing on the reading done on their spare time, even if work-related. We started with a survey sent out to 74 librarians in October 2013, answered by 56, and followed up by interviewing 7 of them in November.We tried to answer these questions:To what extent does the working librarians read on their spare time compared to before they started working?What literature do they read, now compared to before they started working?To what extent does their perception of what they should have read affect their private reading?In what way does a librarian in the beginning of their career differ in reading habits from the reading habits of a librarian with many years in the profession?The result of our study shows that most of the librarians read as much or more than before they started to work. They are more selective in their choice of literature and are affected by their work in it in different ways.

In 1994 the EU directive of packaging waste was adopted. The result was that all EU member states developed different systems to manage packaging waste and recycling. This paper examines the various systems and the factors that affect the level of recycling. This is done by a cross-sectional study between countries. The results of my study suggest that take-back system generates less recycling than other systems, the mandatory deposit system can affect the recycling in a positive way.

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..

Our purpose is to analyse three different epistemological discourses that exist in the social practice, Library and Information Science LIS, using the strategy for interpretation from the mimesis model by Paul Ricoeur and the terms from the critical discourse analysis by Norman Fairclough. The aim is also to explore there different views of knowledge organisation. We review previous research involving epistemology, knowledge organisation and discourse analysis in LIS. These show that there are many different epistemological standpoints and that later research has shown a more critical and sceptical state of knowledge organisation than earlier traditional positivist ideals. Discourse analysis is described as an important theory and method in LIS.
