MAKT, EN FÖRUTSÄTTNING FÖR HJÄLP? : prykiatrihandläggares maktposition gentemot klienten
AbstractAuthor: Ellinor Carlsson and Renate HöjdTitle: "When you can make a difference and when you can´t" the power relation between psychiatricdisability social worker and client [translated title]Supervisor: Eva SkogmanAssessor: Norma MontesinoOne branch of the social works field of research is the relation between social worker andclient. Research has shown that the power and inequality in the relation between helper andperson being helped is needed for the helper to provide help. Power is often mentioned undernegative circumstances such as social workers abuse of their power position, violating theperson being helped. However, Michel Foucault suggests that power is something neutral thatexists in every social interaction. The negative aspects of power are effects of the parties notreaching agreement.
Balansering av en storskalig vindkraftsutbyggnad i Sverige med hjälp av den svenska vattenkraften
This master thesis is a study of the Swedish hydropower capacity to balance wind power. The Swedish government has decided that it should be possible to produce 30 TWh from wind power in the year 2020. The Swedish municipalities have to have plans for wind power plants with total yearly generation of 30 TWh. Wind power is an variable energy source that needs to be balanced by other energy sources. In Sweden the Swedish hydropower can be used for balancing a large scale introduction of wind power.
Triac Driver Platform
In the electronic industrials, power control of AC motors is commonly used. For example power control of a washing machine motor, a vacuum cleaner motor or a coffee machine motor. The company Rejlers Ingenjörer AB has many projects where power control of AC motors is included. A prototype card for this task can save time and money for the company in the future and this is the reason for this thesis.The motors are power controlled by a TRIAC and control of the trigging pulses to the TRIAC. This card is modularly built and can easily be adapted for future projects where the power control of AC motors are included.The prototype card can be used as a subsystem in a larger electronics projects or as it is in lab environment for testing and evaluating new motors..
Kvalitetssäkring i tjänsteföretag : En jämförande studie mellan Ving och SIQ:s riktlinjer för kvalitetssäkring
When managing the quality of a service producing industry?s products, the industry faces greater challenges than the manufacturing industries do. Today?s globalization puts further pressure on service producing companies around the world to work at their absolute maximum. So, how do service producing companies work to manage quality? In this essay the writers take a deeper look at the travel agency Ving, part of My Travel Northern Europe.

Porslinskonsumtion sett ur ett generationsperspektiv: Köpbeteende - Generationskohorter - Porslinsindustrin
During the latest 50 years, the Swedish porcelain tableware industry has gone from being rather successful to experience significant problems. Our empirical study attributes these problems to underlying changes in consumer buying behaviour, whereas current generation theory supports our findings. The younger generation has significantly different preferences compared to older generations, with less focus on quality and more focus on variability, and there is reason to believe that these findings also are applicable to other consumer purchases. The successful porcelain companies of tomorrow will be the ones that continuously can adapt to these and further changes in consumer buying behaviour..
Exkludering som demokratiproblem - En fallstudie av Bolivias demokratiska situation
Bolivia is a multiethnic country where the indigenous people constitute the majority of the population. Despite two decades of attempts to take the democracy further is its foundation more volatile than ever. The aim of this bachelor thesis is to examine if exclusion is taken place in Bolivia from year 1982 until today and if so in which way political exclusion constitute problems of democracy in Bolivia. The answer depends on the understanding of democracy used in the analysis. In this thesis I use theories of process-, participation- and deliberative democracy.
Förebyggande förbättringsarbete med Design for Six Sigma
Design for Six Sigma (DFSS) is a further development of the Six Sigma draft to carry through preventing quality measures in developing and designing of new products and processes. With increasing demands on enterprises development processes to be more safety and faster the need of DFSS arise as a product, process and service development concept in the organisations. Design for Six Sigma aims to improve and structure the development process of an organisation and consider the application of the innovation problem solving. The concept aims to leave the structure of the traditional Six Sigma concept and instead, from an innovative perspective, search for new solutions to existing problems. The concept constitute of a toolbox with a lot of quality tools that are divided into phases in a development model.
Metoder för kartläggning och analys av nätförluster i lågspänningsnät
An important process for grid companies in order to reduce power losses in electricity distribution grids is to figure out where and how they appear. This report describes the factors that cause power losses in low voltage distribution grids and methods for how they could be measured and analyzed. Measurement data for consumed and injected energy were collected for twelve low voltage distribution grids owned by Gävle Energi AB in order to analyze the size of the power losses and how the measurement uncertainty affects the collected data. Then models of three of the grids were created in MATLAB in order to analyze the data and the power losses were calculated to be compared to the collected data. Curve fitting were also used as a method in order to analyze the power losses from collected data.The results show that the losses in the studied grids are low.
"Det var inte mitt val" - en narrativ studie om upplevelser av elektrokonvulsiv terapi (ECT)
This study aims to highlight patients´ experiences about and thoughts of side effects fromelectroconvulsive therapy (ECT), a therapeutic method commonly used when having severedepressions. The framing of questions were how the respondents of this study describe theirlife before, during and after ECT-treatment, how the treatment has affected their daily life andhow these experiences may contribute to the awareness of power in professional relations.The study is based on three semi-structured narrative interviews and the main result showedthat, according to my interpretation, ECT as a treatment obliterated memories, quality of lifeand daily structure for all participants. Unfortunately they have all become subjects ofpsychiatric power and have faced considerable difficulty in getting professional recognitionaccording to their severe memory issues. The respondents have lost the ability to relate totheir past which clearly makes them struggle in their present context. A point in commonamong them is that neither of them wanted ECT but, because of the lack of communicationbetween them as patients and the health care in general, they all ended up getting it..
En undersökning av arbetssätt vid designprocesser
The aim of this study is to explain the paradox of the memberstates willingness to surrender power of important issues such as asylum and refugee policy and therefore partly abandon its sovereignty. We also discuss the relation between internationalization, regionalization and globalization since these processes form the context in which our research problem is found. A case study is used as a method in this paper.In our quest for answers we use a theory of internationalization that we place in its context by primarily discussing the relation between globalization and regionalization. The theory is used as an explanatory force and to give it a concrete form we operationalised its three processes; internationalization of problems, internationalization of the societies and internationalization of the descisionmaking.The result of the case study shows that the increase in asylumseekers leads to a higher risk of negative competition wich give rise to the memberstates need to coordinate their politics.We found that when societies and problems are being internationalized, the state finds it difficult to resolve problems on their own and this leads to the internationalization of the dedescisionmaking. The internationalization of the decision-making process is therefore natural, which in this case means the decisions are taken by the EU rather than by the member states..
Avbrottsfri Kraft med användning av ultrakondensatorer
The supply of uninterruptible power can be applied to many areas wherecontinuous operation is highly prioritized.The application of uninterruptible power for motor operation is facilitatedusing a frequency converter. Direct current operated frequency converters canbe applied directly to the power reserve which removes the need for additionalpower-converting.Batteries have long constituted the power reserve but advancements inthe development of ultracapacitors have created a viable substitution. Ultra-capacitors have high energy storing capabilities and can be applied to highpower applications.Maxwell is a leading manufacturing company of ultracapacitors and pro-vide different modules with built-in solutions for voltage balancing. Unevenvoltages between series-connected capacitors is a phenomenon caused by vary-ing capacitance. A configuration containing Maxwell?s 56V module is createdand constitutes the power reserve in the simulations.The discharge simulation shows a significant current that could damagethe system.
Kvalitetsbegrepp och tv-spelsbestånd - En fallstudie av tv-spelsverksamheten på Malmö stadsbibliotek
The purpose of this thesis is to examine the quality notions used by the library personnel responsible for the video game department at Malmo City Library. Furthermore, the thesis aims to assess how these notions of quality relate to properties of the actual collection of video games. The empirical results are based on interviews with the responsible library personnel. The result is then analyzed by an interpretation of Carl Gustav Johannsen?s library adapted, theory-based, model of quality definitions.
Implementation of a quality management system in food production
The aim of this study was to investigate how the process of implementing a quality management system for food safety was handled in four different food producing companies in Sweden. The aim was also to analyze what difficulties the companies face and the possibilities that arise when certified. Furthermore, the reason for implementation was discussed as well as the main expectations on the certificate. Implementing a quality management system is a good way of ensuring the quality and hygiene of the food production and it also increases the traceability of food products through the whole food chain. A food safety standard provides a method of preventing problems and crisis and it can also help to handle requirements from authorities, the market and others.
Dialog, maktrelationer och våld : En kvalitativ studie om maktrelationer i klassrummet och våld som uttryck för motstånd
Violence against teachers in Swedish schools, according to recent reports has increased and there have been many studies to investigate the situation for teachers. The surveys show that teachers are especially vulnerable to students. This study aims to examine the relationship between a number of teachers and their students to study the power relations that exist in the classroom. This is to see what violence is an expression of and also how violence is perceived by the teachers. The issues that are central in this study are:What is the importance of dialogue in the relationship between these teachers and their students?Is there power relations between teachers and their students?What is the violence against teachers and expression of?Is there any connection between dialogue, power relations and violence?The theories of the materials in this study was analyzed using power relations theories of the historian of ideas Michel Foucault and Philosophy Doctor Anders Persson, who to some extent has his theoretical basis in Foucault?s power relations.
