Socialarbetare : professionell medmänniska eller byråkrat?
The purpose of this study was to examine how social work professionals view their professional role and how they think about the concept of social work. I also wanted to investigate what they believe characterize a professional social work. For the purposes of this study, I chose a qualitative approach in which I interviewed five people linked to the social work. The theories which I have assumed in the analysis of the results are power theory, organization theory and professional theory. The results of this study show that the respondents believe that a professional social work is performed by someone who has training and experience in the field.

Påverkan av skuggor från vindkraftverk
To get rid of our dependence on fossil fuels we need to make use of renewable energy sources like wind power to a greater extent. Even though wind power is a renewable energy source it can still cause some problems for the close environment. One of the problems is shadow flickering. When the sun is low and the wind blows in a direction so that the rotor blades are positioned at right angles to the sunbeams and ?cut? the sunbeams off.
Politecast : ett nytt kommunikationsprimitiv för trådlösa sensornätverk
Wireless sensor networks have the potential for becoming a huge market. Ericsson predicts 50 billion devices interconnected to the Internet by the year 2020. Before that, the devices must be made to be able to withstand years of usage without having to change power source as that would be too costly. These devices are typically small, inexpensive and severally resource constrained. Communication is mainly wireless, and the wireless transceiver on the node is typically the most power hungry component.
?Normative Military Power Europe?: a contradiction in terms? : En fallstudie av EU:s militära insats i Somalia i förhållande till Normative Power Europe.
This thesis paper is based on Ian Manners Normative Power Europe-theory with a focus on EU?s military operation in Somalia. By examining documents from EU institutions in the form of reports concerning EU NAVFOR ? Operation ATALANTA ? EUTM Somalia ? EUCAP NESTOR. This study shows that the Normative Power Europe-theory can get expressed and that the EU continues its normative statements in Somalia. This result is an interesting contribution to the theory of Normative Power Europe witch have gotten a lot of critic about how a military operation should effect and diminish the theory..
Brukarperspektiv på vad som är hjälpande i relationen till professionella : En kunskapsöversikt
The relationship to professionals has proved to be a helping factor for personswith severe mental illness, but it is also a relationship characterised by anunbalanced power relation. The aim of this study was to compile and analyze theknowledge of what persons with severe mental illness themselves consider to behelping in the relationship to professionals, and to specifically analyse this from apower perspective. The analysis was conducted using Foucault?s ideas of powerand knowledge, and an empowerment perspective. The method used was anarrative review.
Energieffektiv högtalare med trådlös kommunikation
Music today is a big part of a person's everyday life and can influence emotions as wellas initiative and motivation. This effect together with development in technology hasled to that music today is accessible and can be played from a large amount of differentkinds of products. This in turn has meant that the demand for smaller audio playbackdevices is greater than ever.The goal of this project is to develop a concept for energy-efficient speakers withwireless communication that has the ability to obtain and play high quality music. Thespeakers will use the latest available technology and at the same time, using digitalsignal processing, have a low environmental impact through high energy efficiencyand low power consumption. Parallel to this work a pilot study will be conducted tosee trends in listener preference of sound.The result achieves the goals pledged while power consumption in sleep mode is solow that they meet the demands of tomorrow.
Maktavstånd och kommunikation - en studie av upplevda och verkliga kulturella skillnader och deras följder
Hofstede constructed a culture dimension called Power Distance, measuring the inequality of Power. Germany and Sweden have relatively similar values according to his world-renowned research. But a series of interviews of Swedish entrepreneurs in Germany shows that these perceive a large difference in inequality of power in the two countries. This essay seeks to explain the difference between these subjective-qualitative experiences and the objective-quantitative data of Hofstedes Power Distance Index. We propose that a combination of differences in communication, exercise and visibility of power and formality influence the way Power Distance is perceived.
EMC problematik och el-kvalitet i elkraftnät
The dissertation deals with an account of actual problem, which can arise within EMC and power quality. The cause of power interruption and what can be done to minimise the power interruption is discussed. It also includes a definition of planning levels and which factors one needs to have control over to carry out a possible planning strategy and how the local distributions net could be more secure. The electrical net could be secure but no system can be free from interruption.The dissertation examines two distribution transformers: GLA40T1 (Glansås) and T399 in Tranås Energy which don?t have regulators.
Empowerment: en studie i ansvar, tilltro och ekonomiskt bistånd
Our understanding is that responsibility is shifting from the community towards the individual within the field of social work. This resulted in our essay, which aims to study how the representatives within social service assistance and churches in Helsingborg work with personal power. Our aim is also to illustrate how these representatives view the boundaries of responsibility between the individual and the community. Our questions are: How do the representatives work with personal power from a micro and macro perspective? How do the representatives look upon their position as representatives? What do the representatives consider as responsibility of the individual respective the community? And; Are there preventing factors from individual responsibility? We obtained our empirical material from a qualitative method consisting of interviews.
Agens i matematikundervisning : En jämförande studie av elevers agens och makt i lärandesituationer där IKT används
The purpose of this study is to investigate how power is distributed in the mathematics classroom and how students achieve agency when ICT (Information and communication technology) is used as a teaching tool. Three learning situations, structured by mathematics, are analysed: in the first situation mathematics is taught in a traditional way, in the second mathematics is taught in interdisciplinary projects, and in the third mathematics is taught using ICT as a pedagogical tool. The theoretical concepts of power and agency are used as analytical tools within a socio-political framework. The concept of power is used to assess the students? ability to influence their learning and degree of inclusion in the three learning situations.
Minivindkraftverks inverkan på lågspänningsnät
Micro-power wind energy convertors have recently increased in popularity. The reasons for this are among other things the increasing cost of electric energy and enviromental concern.In this thesis the connection of these micro-power wind energy convertors to the utility network is discussed. Electric standards for the connection of small production units is presented. Finally some calculations and measurements of electric quality are also presented. The utility network used in the calculations is part of Halmstad Energi och Miljö network..
Den som ger sig in i leken får leken tåla! : En studie om barns maktlekar
Our essay is about children's exercise of power, oppression or domination in games or when playing on school grounds with one and other. We thought it would be interesting to look into how children in preschool and up to the fifth grade use power acts respective power plays in leisure-time. During four days we visited two different after-school center and carried out observations of children during the school day and later inside the recreation centers during leisure activities. In order to analyze our empirical material in relation to power, we have used Magnus Hörnqvist (2012) interpretation of Michel Foucault's theory of power - Another Foucault. We have also used Åsa Bartholdsson (2008) thesis about The regular exercise of power regime ? about normality and power in school.
EU:s normativa närvarande i Makedonien : - en kvalitativ studie

The main purpose has been to look closer with the use of the application of Ian Manners theory of normative power on the Macedonian case. The focus will be to answer the following questions: Does the European Union act as a normative power in relation to Macedonia, if so, how are these values diffused? Has there been any effect of the spreading of these values? Based on six interviews and the available material of European Union strategies for the Macedonian membership I have attempted to understand to what extent the European Union?s normative power has had an influence in Macedonia. The result of my analysis is confirmation of the European Union as a normative power in Macedonia and the understanding of the methods of application..
Implementering av en PSS i Trängslets kraftstation
The purpose of this master thesis is to implement and validate a Power System Stabilizer (PSS) to a generator at Trängslet hydropower station in Dalarna, Sweden. Problems with local rotor oscillations can occur at the hydropower station when power is transferred on a new power line (130 kV) from Northern to Southern part of Dalarna. To ensure good operation properties on this power line Fortum Generation AB and Fortum Distribution AB wants to activate a PSS on a generator.There have been investigations in which situations and what equipment that contributes to rotor oscillations. When this is known the PSS is tuned to damp these oscillations by choosing a good set of parameters. The most important parameters for good performance are to choose amount of gain and phase compensation.
