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.

Suicidology deals a lot with taking into consideration significant symptoms, risk factors and establishing causal relationships which inevitably are very important for suicide prevention. But do we understand the suicide attempters better thereby? The aim with the study is to elucidate the meaning of the lived suicidal experience that is expressed by participants on an Internet forum. Ten participants' texts which concerned own suicidality were chosen out from this Internet forum and were analyzed and interpreted on the basis of a phenomenological hermeneutical method inspired by Ricoeur (1976). The result established twelve themes that with the aid of Heidegger (1993) and Derrida (1978, 1991) led to that the following conclusions could be drawn about the meaning of the suicidal lifeworld: suicidal concern and care in itself reduces the sense of identity, practical suicidal doing in itself reduces the world, sense of identity is more affected by the future than the present and the past, the death is escaped from through a calculating determination to have the death at one's disposal, inability to turn away from the death increases oscillating between states of emotions, the surrounding world's requirement to avoiding death becomes to a compulsion to isolate one self; and finally: to both feel anxiety in front of one self's own death and dread when escaping from it..

This paper examines a long run macroeconomic dilemma. This dilemma states that given a real appreciation, i.e. a continuous increase in the real exchange rate, an economy has two options open with respect to inflation and nominal exchange rate. Either the economy chooses a fixed exchange rate- regime but has to allow for a rising inflation. Or the economy can choose an inflation targeting- regime, but then has to allow for an appreciating nominal exchange rate.

The primary purpose of this thesis is to investigate the operation of membership criteria, which are applied against countries that wish to join the European Union (EU). More specifically, the importance of some criteria in comparison to others is considered. To answer this proposal, three questions are posed: What are the EU membership criteria? Are some criteria more important than other criteria? Does the EU treat candidate countries differently in applying the membership criteria? Three countries are used in this analysis, each country representing one recent enlargement round: Poland (2004), Romania (2007), and current candidate country Turkey. Both official documents, such as EU treaties, and unofficial documents such as statements from EU leaders are used to analyze the application of membership criteria.

ABSTRACTIn this study I have analyzed, throughout a gender perspective, two textbooks Den levandelitteraturen and Upplev litteraturen which are purposed to be used as teaching materials inSwedish schools in the subject of Swedish when teaching the history of literature. The intentof this study was to provide a gender analysis of two textbooks and the focus was on thepresentations of female and male writers, because they have not been studied earlier. In thisstudy, a qualitative text analytic method was used to achieve the best results as possible.Theories used in this study were Yvonne Hirdman?s and Raewyn Connell?s theories. Hirdmanclaims that there are differences between men and women at different levels in the societywhile Connell believes that this is a myth because, according to her, men and women arepsychologically alike.

1 juli år 2013 trädde en ny skollag i kraft i Sverige. Den nya lagen ger papperslösa barn i Sverige rätt till utbildning. Detta gäller både om barnet har fått avslag av Migrationsverket på sin uppehållstillståndsansökan och om barnet lever gömt och inte sökt uppehållstillstånd. Idag har papperslösa barn rätt till utbildning men detta innebär inte att dessa barn har en skolplikt, utan det avgör barnet själv eller familjen till det papperslösa barnet om rätten ska nyttjas. Denna valfrihet leder till att flera papperslösa barn inte utnyttjar sin rätt till utbildning.

The paper examines how human inner properties and the interpretation of the external worldare explained and presented in Dark City (Alex Proyas, 1998). Aspects as the relationship between the body and soul/consciousness, body snatching, memory transferences and dystopian cities are analyzed. The field of study is compared to a general science-fiction film perspective regarding the aspects. Dark City contains an alien race with a common mind, but who lacks soul and individuality. They represent what humanity can become if the scientific development goes too far.

The purpose of the essay was to examine the role of the professional communicator in the Swedish Unemployment Funds. Focus was on measures carried out by the communicator to enhance and streamline communication and how the communicator supports their coworkers in their own communication role. In order to fulfill the purpose, two main questions were asked;? How do the communicators support and develop their coworkers communication role?? What to the communicators identify as challenges in their work in doing this?The theoretical base of the essay was Heide and Simonssons (2011) challenges for the professional communicator. The theory states that organizations communication processes are the foundation to its existence and development and that the professional communicator therefore needs a solid base with the possibility to monitor the whole organization.A questionnaire was sent to communicators in all Swedish Unemployment Funds and even though the non-response was rather considerable, the answers received was assessed sufficient to make an analysis.

The purpose of this Master thesis is to compare the perception and significance of reference work in two countries, Sweden and Germany. This will be achieved by means of a literature review of previous research literature and public documents and a content analysis of articles from two library journals.A first step was to examine the historical development of reference work in the selected countries. In connection with this there proved to be distinct phases in the discussion regarding reference work. These phases with their specific discourses, themes and emphases reflected and thus later were confirmed in the second part of the study.The results show that despite some similarities there are also quite a few differences in how reference work is perceived in both countries. For Sweden, the idea of reference work was introduced relatively early.

The purpose of this essay is to study two film adaptations of the original Planet of the Apes novel and see what kind of relationship the two adaptations have with each other. The main question is if the secondary film adaptation is restricted by the primary and if the relationships between these two are as two separate adaptations or as a remake of an adaptation. What the results of the study show is that the secondary adaptation can not be seen as a remake even though it gets some of its inspiration from both the original story as well as the primary adaptation. The secondary adaptation is, however, restricted in what it can adapt due to the primary adaptation having the first pick, at least if the secondary adaptation wishes to be a whole new adaptation and not a remake of the primary. The study shows also that the fidelity in the secondary adaptation is not necessarily to either the original or the primary but to the knowledge the audience has about the Planet of the Apes universe which they have gathered from all of the important versions of the story.

Researchers in the field of political corruption generally expect voters in democratic states to lose trust in corrupted politicians. However, there are cases where corrupted politicians maintain their popularity, a phenomenon studied in this thesis. Focus lies on three cases of political corruption: the Italian Prime Minister Silvio Berlusconi who has been the subject of several judicial investigations and court cases; the impeached former president of Lithuania, Rolandas Paksas; and the German Christian Democratic Union's (CDU) involvement in a party funding scandal. The cases are chosen based on the method of agreement. Berlusconi, Paksas and CDU have all, in spite of their corrupt behaviour, kept or regained popular support among a large group of their country's citizens.

This report, written by Ma?ns Ridze?n and Jonas Stenberg, presents the thesis carried out the spring of 2012. The authors met the first time in 2008, when they started their studies at Uppsala University. Since then they have completed various projects, both within and without the university. This study is based on a theory that was first conceived when Jonas Stenberg did his internship in the summer of 2010.

The aim of this essay was to gain a deeper understanding about how school employees interpret and practice school law regarding cyber-bullying that occurs between pupils on the internet. To examine this we used a qualitative method. We completed eight interviews with five teachers, one headmaster, one school welfare officer and one special educationist. These eight school employees were from four different high schools. In our interviews we found that the school employees thought it was difficult to define different concepts within the school law such as in association with the occupation and offensive behaviour which prohibits them from interpreting the school law in the same way.

Den första januari 2004 vann Lag (2003:778) om skydd mot olyckor laga kraft och ersatte Räddningstjänstlagen (1986:1102), detta var startskottet för ett nytt sätt att se på brandskydd och brandskyddsarbete i Sverige.Den nya lagen förde över en större del av ansvaret för brandskyddet på den enskilde och minskade på så vis myndigheternas skyldigheter och inverkan på brandskyddet; det personliga ansvaret stärktes och en ny betoning på att arbeta kontinuerligt och konsekvent med brandsäkerhet infördes, att arbeta systematiskt med brandskyddsarbetet.För de flesta privatpersoner och företag innebar detta inte någon större förändring då de flesta lagar som reglerar det rent tekniska brandskyddet de facto befinner sig i annan lagstiftning än Räddningstjänstlagen/LSO. Den stora förändringen kom hos de företag som har verksamhet där en olycka kan innebära fara för allvarliga skador på människor och miljö, så kallade 2.4-anläggningar. Dessa anläggningar har, sedan LSO infördes, fått ta över ett mycket större ansvar för att kontrollera sitt brandskydd och se till att det bedrivs ett systematiskt brandskyddsarbete på arbetsplatsen.AarhusKarlshamn AB (AAK) är en internationell koncern som utvecklar och tillverkar vegetabiliska fetter för mat, konfektyr, kosmetika och tekniska produkter. Fabriken i Karlshamn har existerat i nästan ett sekel och har länge varit en av de viktigaste arbetsgivarna i Karlshamns kommun. Trots att industrin verkar 24 timmar om dygnet med uppåt 600 skiftanställda och hanterar stora mängder brandfarliga och giftiga ämnen har de en förvånansvärt låg brandrelaterad tillbuds- och olycksstatistik; ca 50 automatlarm om året och färre än 10 % av dem är riktiga incidenter.
