I have studied how network in a broad sense can affect decision-making. The primary purpose is to see if the political initiative somewhere disappears when it comes to understand the relations between power, actors and politics. The study discuss in a theoretical area that concerns the reliability in neoinstitutionalism to use as an analytical instrument. Some criticism is given to the theoretical standpoint in the sense that there is no power perspective included in the theory. I include a discussion about a concept of power, which I include to the theory.

This paper intends to examine the knowledge challenges in small IT companies which is going through rapid growth. The movement of information and knowledge is a social and very complex process.

In order to understand how technology can support information and knowledge management one needs to understand what information and knowledge is.

Syftet med denna studie är att undersöka lärarens arbete med lärplattor i förskolan. Studien har tre frågeställningar; 1) Hur beskriver förskollärarna sin syn på lärplattan som pedagogiskt verktyg? 2) Hur beskriver förskollärarna sitt arbete med lärplattan? 3) Hur beskriver förskollärarna lärplattans tillgänglighet för alla barn? Studien genomfördes på en förskola i Mellansverige. Intervjuer med fyra förskollärare genomfördes. Intervjuerna utfördes med en semistrukturerad design; en intervjuform där det finns goda möjligheter anpassa intervjun efter respondenten.

The aim of this essay was to obtain an understanding about company owners thinking about the connection between having an own company, and the risks for an alcoholic abuse. The risk factor I was researching was stress, alcoholic culture, accessibility and rehabilitation.I have interviewed five owners of small companies, two women and three men, which represents four different kinds of branches. The theories I used in analysing the empirical findings where the theories of psychosocial work environment of Lazarus, Karaseks demand/control model, epidemiology- and culture perspective.I have found that the main stress factors for company owners where the economical stress and great load of work. The stress was also related to the fact that company owners of small companies often were alone with all the responsibility and problems.Women did not use alcohol very often as a tool to reduce stress. If individuals were using alcohol to reduce their stress, it also had to deal with their ability of coping and also what channels they had for coping..

In this thesis the construction of identity within the EU is discussed. A thesis problem in three dimensions is used to explain the purpose of the construction, its realization and the consequences of such identity. These aspects show the complexity of the problems related to identity construction on a structural level.By using a post-modern and a social constructivist theoretical approach identity is presented as socially constructed by discourse. The theory of discourse makes it possible to analyze the development of an identity forming discourse within the EU and its status today.With an approach inspired by critical theory, we use discourse analysis as a methodological tool to illustrate the ideas that govern discourse, and in what way it is related to the social reality.The analysis states that the purpose of identity constructing is the striving for legitimacy. Without identification, the legitimacy is threatened.

This thesis is about how ideology affects the way leadership literature measures good and bad leadership qualities. The paper argues that ideological influences in leadership literature, from a teacher perspective, complicate the understanding of leadership in its practice and theory. The methodological tool used in this thesis is an idea- and ideology analysis approach applied on leadership literature that is used in teacher education. A theoretical discussion about the definition of leadership and its possible ideological connotations sets a frame for measuring ideological influences in the texts. The analysis from the textbooks showed clear signs of ideological influences when talking about leadership.

This thesis examines the relationship between recognition of prior learning and the aim to increase social and ethnical diversity in higher education. Recognition of prior learning is a result of educational politics aiming to broaden social and ethnical recruitment to higher education. By examining if recognition of prior learning rather can, and shall, be seen as part of what Pierre Bourdieu calls educational social reproduction I try to question whether it fulfils education policy goals or not. My results show that persons responsible for recognition of prior learning rather recognise knowledge from prior educational institutions than knowledge gained outside the educational system. Considering this, recognition of prior learning does not quite live up to the aims.

This degree project aims to investigate the potential and possibilities for conceptual energyanalyses in the early stages of the design process. Many key decisions are made in theearly stages of a project regarding the shape and orientation of the building. Conceptualenergy analyses can provide the architects with insight regarding different design option?srelative energy performance.As the demands for more sustainable buildings increases, so does the need for earlyenergy analyses. Performing analyses in the early stage requires many assumptions andguesswork which could lead to a large margin of error.The offering from Autodesk is a module in Revit Architecture/MEP and the stand aloneprogram Project Vasari (under development).

This thesis describes the introduction of Web 2.0 education into Swedish LIS education with emphasis on the driving forces and obstacles in the process. It also discusses the possibilities of estimating the appropriate time for the start of new educational courses introducing new technologies, when it is uncertain if the technologies in question will sustain for a long enough period of time to make the educational effort worthwhile. The data on the Web 2.0 education was collected during the spring of 2010 from the Web pages of the five LIS departments in Sweden, namely Borås, Lund, Umeå, Uppsala and Växjö, as well as by 10 interviews during November and December 2010 with two representatives from each LIS department..The key finding is that Web 2.0 is covered in Swedish LIS education and embracing both practical and theoretical issues. The main driving forces have been both the needs of the profession and an academic research interest. It is concluded that Rogers??S-curves? as described in ?Diffusion of Innovation? can be used as a tool in order to improve the understanding of when to introduce education in new technologies.

The purpose of this master?s thesis is to examine the use of the concept cultural heritage in Swedish governmental cultural policy. Ten official reports, reaching over a time period of seven years (1997-2004) are examined in the following way: What is cultural heritage? What functions/ values does the cultural heritage have? Whose heritage is a cultural heritage? With some simplification you can say that there are two different views on cultural heritage in the documents. The most common way to refer to cultural heritage is a category of chosen historical objects whose preservation is motivated by their function as sources of information and knowledge about the history and development of the Swedish society.

The purpose of this essay is to study how the local creators of a "master plan" for the swedish city Kristinehamn, the years between 1940 to -43, looked on their planning. It is an analysis of ideas case study. A hypothesis is upheld for the research: that the local physical planning had largely extended ambitions what regards central state control in a way that is similar to planned economy. Questions that are asked include: Was the planning assumed to be a tool for the state to regulate the environment? Can the planning be seen as a mean to control the society in time and space? The essay search for verification of the hypothesis by a theoretical analysis apparatus made upp of ideal types.
