Det nya IV-programmet : en kvalitativ textanalys
The purpose of this study is to examine the view of knowledge and the view of learner which are prominent in the ministry memorandum Specific programs and access to vocational programs (U2009/5552/G) and thereby understand the potential impact of the new transformation of the current individual program and what it brings to the students who do not achieve the objectives in grade 9. We have used a qualitative text analysis method. The background to the study describes in particular today's individual program, view of knowledge and view of learner. The result shows that the most prominent in the memorandum is that knowledge is divided into theory and practice, that individualization is the focus and the text shows freedom for interpretation..
Samhällets Sårbarhet för Klimatförändringarna
The effects of the climate changes are expected to generate several substantial direct and indirect consequences on both ecosystems and societies. It is the extent of the negative consequences that determents the vulnerability of the things or the ones exposed. The knowledge of the effects and consequences by a changing climate provides an opportunity to take measures to reduce the vulnerability.Our society?s vulnerability depends on how we choose to act out of the existing knowledge and what measures we choose to take. Karlstad municipality has good knowledge and perception of the increased flood risks the climate changes will generate and the probable consequences that most likely will follow. How the municipality decides to manage the flooding issue is not just affected by the will to mitigate the vulnerability but also by the vision to increase the number of citizens.
En studie om förutsättningar för ledarskap i kunskapsintensiva verksamheter
Title: A study about conditions for leadership in knowledge-intensive firms.Authors: Cecilia Ekström and Niklas SandbergKeywords: Leadership, knowledge-intensive firm, hierarchies, followers.Background: Leadership is becoming one of our greatest social myths and is considered a total solution for many problems that occur in an organization. The view of leadership is usually from a top-down perspective, which contributes to an often underestimated view of the follower. Just as it is important to understand the leader's view of leadership, it is important to understand how employees view the structure from which the leader derives its legitimacy. The existing conditions in knowledge-intensive firms, such as autonomy, place special demands on the formal leadership.Purpose: The purpose of this study takes an employee perspective, to understand what the conditions are for formal leadership in knowledge-intensive firms.Method: A qualitative research method was used and empirical material was collected through interviews with employees in knowledge-intensive firms. The empirical material was analyzed by the respondents? mental images which were set against the theoretical framework of the thesis.Conclusions: The conditions for formal leadership in knowledge-intensive firms make it advantageous to have a leader with a withdrawn role.
Uljabuouda vindkraftpark turbinmodellering och stabilitetsanalys
This master thesis has been performed at Solvina in Gothenburg for Skellefteå Kraftand Vattenfall Eldistribution. The aim of it is to investigate the consequences of theinstallation of a wind power plant on the mountain Uljabuouda in the vicinity ofArjeplog. Especially the impacts on voltage and transient stability are examined.Furthermore, the amount of extra strain on the voltage regulation equipment and theneeds for increased regulation capabilities are looked into.The wind power plant is planned to be built by Skellefteå Kraft and connected to a130 kV grid owned by Vattenfall Eldistribution. The work comprehends the followingmain parts:- Theoretical studies aimed at wind turbines and power system stability issues.- Modelling of the type of wind turbines assumed to be built on Uljabuouda.- Simulations of different operation cases and analysis of the simulation results.The results from the simulations show that, as far as voltage stability and extraworkload on tap-changers are concerned, the wind power plant does not, in anysignificant manner, worsen the present conditions. The problem of overloading theline between Arvidsjaur and Vargfors is also minor.
Utvärdering av konsekvenserna för nätanslutning av vindkraftparker i Sverige vid införandet av nätkoden Requirements for Generators
Grid codes are becoming more demanding on power generating units due to the factthat the complexity of the power grid is increasing. The penetration of wind powerhas grown over the last years and it is clear that wind farms need to be addressedwith the same type of grid codes as conventional generation units. There is howeveran undeniable difference between the technology in conventional synchronousgeneration units, and the asynchronous generation units in wind farms.This thesis has reviewed the current grid code in Sweden and compared it to the newcode proposed by ENTSO-E, ?the Requirements for Generators?, in the aspect ofwind farms with an installed power of 30 MW or more. The comparison has beencomplemented by an analysis of how wind farms of two different technologies(Doubly fed induction generators and full power converters) can meet therequirements and technical proposals have been given on how to be able to meetcompliance with the new grid codes.The Requirements for Generators contains many non-exhaustive and optionalrequirements, because of this it has been difficult to, at this stage, exactly point outthe technical impact on the grid connection of future wind farms in Sweden.
Bors E23 - Framtagning av eldriven röravklippningsmaskin
Our Bachelor´s Thesis has been performed in co-operation with Bors Automation & Tool AB.Our task was to develop a servomotor powered tube cutting-machine with initial point fromtoday's hydraulic driven tube cutting machine Bors HYD 23. The purpose with the newconstruction was to achieve a more power-efficient tube cutting machine which could lowerthe power consumption, and also meet the market continued growing demand forenvironmental-conscious production.Bors Automation & Tool gave us relatively free hands in order to enable new thinking ideaswithout following their traditional constructional solutions.Our solution resulted in a construction based on a power source existing of a servomotordrivenrollerscrew, witch provides a more rational use of energy compared with the currentmethod.Bors Automation & Tool AB has decided to fabricate a prototype of Bors E 23 during theautumn of 2007, which they are planning to revile at the Tube 2008 exhibition in Düsseldorf,Germany.NOTE:Due to an agreement signed by the authors in the beginning of this project, no appendix is published at this time.If you want to wiew these documents, please contact the authors..
Det handlar om tur: en kvalitativ studie av rättsprocessen vid kvinnofridsbrott
The purpose of this essay was to examine the experience of the judicial process concerning domestic violence from the perspectives of abused females and from some of the authorities and organisations which meet these women. The essay investigated several views of the judicial process in order to obtain a wide perspective. It responded to the following questions:- How are abused women treated by the authorities and organisations?- Are there enough resources and knowledge among the authorities and organisations?- Is there any collaboration between the authorities and organisations which the female meets in the judicial process and if so, how does it look like?- What does the aspect of security of person look like for the women which have been exposed to domestic violence?- What in the judicial process is important for the women's ability to move on in her life after experiences of violence in a relationship?This study was based on a qualitative method, where the interviews constituted of empirical material. The essay was based on interviews with two females who have experiences of violence in a relationship, two social workers from Kvinnojouren in Lund, two social workers from Kriscentrum in Lund, one lawyer, one prosecutor, one policeman and one social worker from Kvinnoforum in Lund.
Tidssynkroniserade mätningar i vattenkraftstationer
Vattenfall and Svenska Kraftnät perform start-up tests, where hydropower generators are used to power up the electrical grid in case of a blackout. To monitor the electrical grid, Phasor Measurement Units (PMU) are used. Each PMU is individually equipped with a GPS-receiver to precisely timestamp the data relative to the official time UTC. During the test, it is also of interest to timestamp the measurement signals from individual hydropower generators to later compare with PMU-data, and thus study the power grids impact on the generator. The aim is to work out an appropriate method to make these measurements and to build a data acquisition system, capable of timestamp data relative to UTC, from a generator in one of Vattenfalls hydroelectric power stations. The problem is that the generator is located in an underground station which hampers the reception of GPS-signals and wiring should be avoided if possible. Time synchronization has been solved by using Vattenfalls network, which is synchronized by the network protocol NTP.
Energiewendes påverkan på det nordiska kraftsystemet
Both the German and the Nordic power markets are seeing dramatically changed conditions due to an ongoing process of expanding the share of renewable production in the systems. For the German part this comes from heavy subsidies which have led to an explosive development in installed capacity of photovoltaic and wind based production. After the Fukushima incident it has been decided to shut down all Germanys nuclear plants. This capacity drop is however not of the same magnitude as the
increase in renewables, but will impact the stability of the power system. The Nordic power system which already has a surplus of power sees an even further increase, coming mainly from construction of new nuclear plants in Finland and a general increase in wind farms.
Att möta vampyren : Hur kan Twilight behandlas i skolan?
This essay discusses how popular literature in general and Stephanie Meyer?s Twilight-series in particular can be useful in the classroom, despite, or rather, thanks to, its inherent problems concerning gender roles, relationships and the power systems within them. The essay takes a reader and teacher centered approach in describing both the problems of Twilight and the ways these problems can be worked with in the context of the school subject Swedish in upper secondary school. It makes an inventory of Twilight?s problematic aspects, and attempts to use them in conjunction with the governing documents of the Swedish school system.
Naturvetenskap i grundskolans lägre åldrar : Om lärares förhållningssätt gentemot ämnet
This investigation is about how teachers in school can motivate and create interest for science among younger children. Teachers were interviewed about attitudes to their subject and how this affects their lessons.I have also tried to find out, both by interviewes but also by studying litterature, what the most important thing is to teach in science, which knowledge is necessarry in the future and why.My result indicates that teachers find science both interesting and important but at the same time they also think it is a difficult subject to teach even if they are educated. Both the litterature and the teachers in my study agree that knowledge in science gives us a chance to ask questions, take stands and solve problems and that this knowledge is important for us in our future..
Flickor i en mångkulturell skola
Background: The main purpose of our study is to try to give an idea of what a multicultural school is and what difficulties girls find with Swedish as a second language. We are at the end of our teacher education, which means that in a few months, we will be responsible for creating environments that are conducive to the students and to ensure that opportunities that allow the students to develop exist. We are aware that in a multicultural school that we no have in Sweden there has been some discussion regarding the Swedish language, which can be interpreted as the Swedish language being at a disadvantage with the students because of all the integration that occurs in schools and the lack of knowledge regarding the different cultural backgrounds. To get this knowledge we had to seek more knowledge on the subject.
Intranät : en kunskapskälla i arbetet?
The ambition with this study is to look into and create an understanding for how an intranet can work as a support system in work processes in capacity as a source of knowledge. We want to enhance the understanding for which kind of knowledge that can be coded in and transmitted by an intranet, and which that is lost in this process. We also want to clarify what it takes to get this knowledge, in collaboration with the intranet, to support the work in an organization. It is a qualitative case study at a Swedish bank. It consisted of semi standardized, half structured interviews with five people in one of the bank?s local offices.

New public management och den svenska gymnasieskolan : En ideologikritisk analys av Gy11-reformen kopplat till organisationskonceptet new public management
The purpose of this ideology critical study is to investigate the hidden content in the reform Gy11 and compare it with the concept new public management. After the clarification of the hidden content, we compare the structure of the organization in Swedish high schools with the structure in public sector called new public management. The main questions of this study are the following: Is it possible to see the foundation of new public management in the Swedish high schools when it comes to the views of knowledge and the formation of goals? Which similarities can we find when we look at the organization new public management and the Swedish high school?The result showed many similarities, both regarding the views of knowledge and the formations of goals. The structure of new public management has been largely implemented in the Swedish high schools and the schools now focus more on instrumental knowledge rather than universal knowledge based on understanding.This is not surprising due to the social progress.
