Today?s wind power plants are only compensated for their reactive power consumption at no-load. As the wind power plants grow bigger the amount of reactive power they need also increases. This is no longer a problem that can be ignored, especially as the net owners are beginning to charge the reactive power they transport.In this thesis a couple of different methods of compensation and their prices will be discussed and evaluated. Problems, such as self-excitation, that can occur if one fully compensates the wind power plant will also be brought to surface.

It has been demonstrated in this study how people working in frontline jobs in service organizations are exercising ?micro power?. The use of ?micro power? is defined as ?to in ones professional role, without objectively defensible reasons, impose sanctions on a customer?. The interviewees are explaining their use of ?micro power? with mood, working conditions, and customers? behavior.

In this paper we investigate whether power structures in organizations have an influence in the process that leads to burnout. We analyze if these power structures affect the individual?s health condition toward burnout in a way that leads to disability and subsequent absence from work. In the study, six persons who all have been unable to work due to burnout have been studied through qualitative, semi-structured interviews. The material have been coded with three different themes; leadership and hierarchy, responsibility and delegation of responsibility and performance and loyalty.

Purpose: The purpose of this paper is to describe the perception of value and risk in CSR as well as analyzing how financial institutions influence responsible behavior in business in order to create sustainable economic growth.Methodology: The study has a qualitative research method used by an abductive process. Data has been collected through semi-structured interviews with respondents from three venture capital companies and three banks. The sample of respondents was done through a convenience sample with respect to access and expertise in the research area.Conclusion: The most important meanings of the research results have shown that CSR holds an intrinsic value concerning contributing value as its conceptual meaning in terms of sustainable development. CSR can also be regarded as a dimension of risk management to reduce the risk of negative externalities on corporate activities. Investors and financiers contribute to sustainable companies through active ownership and improvements in the CSR dimensions.

The intension of this study is to investigate the interaction between teachers and social workers in two diffrent countys. The study is focused on how teachers act upon suspicions when there are children at risk and what kind of support the teacher gets from social workers. Another importent question is if the teachers know what kind of rules regarding to confidentiality and if it would be better for the pupils if there were no confidentiality.To get answers to my questions, i have interviewed teachers and social workers in both countys.In this study I assume that the power has three dimensions and that there are four levels of interaction.Due to the law about confidentiality the social worker has the power over the teachers. Because the law about confidentiality it is difficult for teachers and social workers to interact.If the teacher want help from social services, she or he must call the social worker because the social worker will not call the teacher. If the social worker want to help the teacher and give her advice, the social worker can do that without breaking confidentiality.

This essay analyse the relationships between scientific paradigms and different logics of power in the field of psychiatry, primarily in the fields of attention disorders of children and schizophrenia. In these two fields of psychiatric research and treatment, there exist two scientific paradigms, a biological/neuropsychiatric and a socialpsychological, working from different standpoints regarding questions of ontology, epistemology and theories of value. Drawing from Thomas Kuhns paradigmatic theory of science, and Michel Foucaults concept of power, this essay proposes that different paradigmatic standpoints gives rise to different logics of power. Relying on the concept of power/knowledge and different paradigmatic standpoints, the essay states that the biological/neuropsychiatric paradigm produces a biological individualising logic of power that fixes the individual to his/hers biological condition. This in contrast to the socialpsychological paradigm, which on the basis of its paradigmatic standpoints produces a social-group related logic of power.

Den omgivning organisationer idag ställs inför blir alltmer krävande. En allt hårdare reglering, hot från nya teknologier, samt de företagsskandaler som härjat i media, har lett till att dagens organisationer ser på risk på ett nytt sätt. En utveckling som nyligen skett inom riskhantering är Enterprise Risk Management (ERM). Denna uppsats undersöker den roll ERM, och i synnerhet ett nyutvecklat ramverk som används för att implementera ERM, har i en organisations riskarbete. Ramverket, COSO:s ERM, består av åtta kontrollpunkter som enligt ramverket bör finnas i en organisation som utför sitt ERM-arbete på ett korrekt sätt.Studiens syfte är att undersöka likheter och olikheter mellan en organisations riskarbete och COSO:s riskhanteringsramverk samt den teoribildning som skapats kring Enterprise Risk Management.

En kvantitativ studie av incitament och avkastning på 338 aktie- och 33 hedgefonder med säte i Sverige genom att variablerna fondförmögenhet, antal fonder i fondbolaget, prestationsbaserad avgift samt prestationsbaserad lön testas mot avkastning och risk. Vi finner att en större fondförmögenhet leder till lägre avkastning, fler fonder i fondbolaget resulterar även det i lägre avkastning för fonden än för motsvarande i ett fondbolag med färre antal fonder. Vår variabel prestationsbaserad lön resulterar i lägre risk för fonden och vår variabel prestationsbaserad avgift resulterar i högre risk. Vi kan inte utifrån våra resultat fastslå att agentteorins antaganden om incitament och kontroll i svenska fonder har en avgörande roll. Däremot hittar vi effekter vilka sannolikt har sin förklaring i agentteorin men då de inte är entydiga går det inte att generalisera sambandet..

Bakgrund: Det rådande pensionssystemet i Sverige består av sex så kallade AP-fonder. Genom åren har pensionssystemet flertalet gånger kritiserats för dess låga avkastning.Problem: Vår huvudfråga är att jämföra AP-fondernas risk och avkastning med aktiemarknaden som helhet, detta ska ske med hjälp av två jämförelseindex: MSCI World och SIXRX.Syfte: Syftet med uppsatsen är att jämföra de fyra första AP-fondernas risk och avkastning med aktiemarknaden som helhet under åren 2002-2010.Metod: Vi har använt oss av en kvantitativ metod, genom att samla in information från AP-fondernas årsredovisningar och hemsidor. Vi har samlat in historisk data, som vi sedan har bearbetat och analyserat.Slutsats: De studerade AP-fonderna har presterat sämre än aktiemarknaden..

Purpose: To explore how the changes in work life, here represented and depicted through the concepts of knowledge work and knowledge worker, have been incorporated in the official psychosocial work environment discourse in Sweden. Methodology: Critical discourse analysis, contrasting the official psychosocial work environment discourse to literature on knowledge work and knowledge worker, to explore how employees, employers and their relations are constructed within these two discourses; focusing identity, autonomy and power. Using the constructions to make visible how they are articulated, used and dealt with in a real life case from the Work Environment Authority. Theoretical perspectives: Our social world is socially constructed and language is the main tool for constructing it. Discourse analysis is thus not just a tool for deconstructing texts but also for enhanced understanding of our construction of the world and our ability to communicate about it.

Purpose: The main purpose of this study is to study the 45 funds, divided into three differentdivisions, then the result will provide a greater understanding of how returns change with ahigher risk.Methodology: The study is based on a quantitative approach. The survey was conducted bygathering raw data from databases and secondary data from literature, printed and electronicsources.Theoretical perspectives: The study is based on the theory: the efficient markethypothesis, which argues that future returns can not be calculated as the market is fullyinformed. The study is therefore studying historical yields.Empirical foundation: Empirical data are acquired from www.morningstar.se, andtherefore also treated on this page. The material is then divided into documents and time axes.Conclusions: The study has shown that high-risk funds give a higher percentage returns thanmedium-and low-risk funds. However, does not imply a higher risk automatically earn ahigher return when the low-risk funds have shown a higher yield than medium-risk funds.

As a consequence of increasing wind power installations in the Nordic grid the last years, the need for regulating power has become larger. In the Nordic grid, regulating power is mainly provided by hydro power. One part of the regulating power is called frequency control, which ensures that the grid frequency is stable and close to 50 Hz.However, setting the turbine into frequency controlled operation may cause stress and wear of the components in the mechanical control system. Frequency controlling implies large and frequent servo forces and longer travelling distance of the sliding bearings in the Kaplan turbine.Based on one selected Kaplan turbine, Selsfors G1, measurements and MATLAB calculations have been performed in order to determine forces and movements of the linkage system. With these forces and movements as input, stresses and fatigue have been determined as well as sliding distances, bearing pressures and wear of bearings during a typical lifetime of 40 years.The results indicate that no severe wear exists on the bearings during 40 years of service.

New technology makes it possible to remotely measure all consumers in a power network onan hourly basis and store the values in a database.This thesis work describes the conversion process between automatic meter reading systemMActor and calculation software Xpower.Then the possible differences between calculations of power networks using load curves incombination with a yearly estimate of consumption and calculations using hourly measuredvalues is examined.The result of the comparison shows that, for the power network under inspection, nosignificant difference could be noticed. This does not mean that calculations using hourlymeasured values would be unnecessary. I believe that in a near future calculations using hourmeasurements will be the primary choice for many power companies to whom technology isavailable.Also some basic calculations of fundamental power network parameters, such as power factorand loses, are presented using hourly measured distribution transformers in combinations withits hourly measured loads.The report is written in Swedish.

The purpose of this thesis is to identify power structures and instruments of power within the Jehovah?s witnesses and investigate how they affect the baptized youths baptized within the organization. The material consists of qualitative in-depth interviews and is analyzed with Foucault's theories of power. The results show that the participants have a very strict relationship to the rules of the congregation and also that they take great care in observing these rules carefully. It becomes evident that young members are exposed to disciplinary measures from the organization.
