När psykiatrin vände sig åt samhället : Om psykiatridebatt, sektoriseringsplaner och Nackaprojektet 1968-81

This essay revolves around the reformation and sectorization of Swedish psychiatry starting in the 1970?s. Psychiatry was to change from being based in closed asylums to being an institution in the middle of society, finding social solutions to mental illness and working through a dynamic network of various care givers, such as welfare officers, nurses and psychiatrists. This new kind of psychiatry was first tested in Nacka, where psychiatric reformers Johan Cullberg and Bengt Berggren were the heads of a six-year long pioneer project of sectorized psychiatric care. My specific purpose is to analyze the new ideas of mental illness and of psychiatry?s role in society which were introduced in this project and how they were expressed in the official reports presenting it.The reformation was preceded by a public debate concerning psychiatry, which had intensified a few years around 1970.

Smart konsumtion : unga vuxnas attityd till miljö- och rättvisemärkta produkter

We are more aware than ever about our impact on the common environment and the world's population. Consumption awareness can be one way to take social and environmental responsibility. This study aims to examine young adults' (19-30 years) attitudes toward consumption awareness in Sweden. Consumption awareness is treated in this study as the consumption of environmental and fair-trade labeled products that have been certified of a third party. The study is limited to everyday commodities, which in this case is groceries, household consumables and clothing.

Simulering av simulinkmodeller med Extended Kalman Filter

Simulations of simulink models using Kalman filters are often very time-consuming. This problem depends mainly on the fact that the Kalman correction has to be performed at each sample instance through the whole simulation. The goal for this thesis work is to reduce that time-consumption for the filtering part (the integration partis treated in a complementary report) of a simulation. Furthermore a Matlab routine to perform parameter tuning and finally a graphical user interface is developed.The filtering part of the simulation in this thesis is based on an Extended Kalman Filter (EKF). The time optimization of this filter considers searching for the possibility to replace the today?s existing Matlab functions that is used to perform the filtering calculations.

Prediktionsmodell för graviditet vid in vitro-fertilisering med ett frys-tinat embryo

SEB Merchant Banking provides to its institutional customers a true market neutral product called Dynamic Manager Alpha (DMA). The DMA is constructed by a long position in an exceptionally well performing mutual fund and a beta adjusted short position in an appropriate index. The key to making the product market neutral is adjusting with the correct beta, since the beta changes, it is very important to have a good model for predicting beta in the future.This master thesis begins with describing what beta is in a CAPM sense. It then continues with recognizing the so called ?Two Beta Trap?, which separates two kinds of beta.

Mekanisk integration av en IR-detektor i en Stirlingkylare

The master thesis ?Mechanical Integration of an IR-detector in a Micro Cooler? has beenperformed at FLIR Systems AB in Danderyd. FLIR Systems is a world leader in the design,manufacture and marketing of thermal imaging camera systems.The thesis project is divided into to two areas, Production Method and Noise.The Production Method concerns the positioning of a detector on the cold finger within the IRcamera.The detector has to be positiond with very high accuracy at the center of the cold finger,so it can be placed in line with the optical axis to avoid movement of the picture during zooming.The positioning of the detector is at present done with the help of specially designed guides on aplate on top of the cold finger. The design workes well but the special machining needed for thisplate is very expensive.The goal concerning the production method was to derive a new more cost effective method forthe assembling and positioning of the detector on the cold finger by replacing the guides on theplate with a reusable equipment or some other alignement operation.Several concept ideas have been generated with the help of concept generation methods in theform of concept classification trees and concept combinational tables. Two of these conceptswere selected to be further refined.

Lane Keeping Aid : ett förarstödjande system för bilar

Many traffic incidents are due to the driver?s lack of attention, resulting in dangerous lane departures, either sliding off theroad or into the oppose lane. These kinds of incidents often have serious outcomes, which has led to much effort being concentrated on preventing or lessening the damages when the incident is already a fact, for example by installing safety belts and air bags. These measures may be considered to be acts of so-called passive safety. Active safety on the other hand, means that the safety systems intervene before the incidents have occurred.

Utvärdering av en väggkonstruktion utan PE-folie : Med en undersökning av hårdvaxolja som diffusions-/konvektionsspärr

District heating covers around 80 % of the heating demand in apartment buildings and 10 % in single-family homes in Sweden. In the year 2010 the total input of energy to the Swedish district heating grids was about 70 TWh, which corresponds to 11 % of the total energy input to the whole energy system in the country. Through the combined production of heat and power the CHP-plants often reaches an efficiency of 90 % from energy in the fuel to produced heat and power. In order to keep the efficiency high it is important for the owners of the plant to have good knowledge about the plants performance at different operation points. Strängnäs Energi AB initiated this diploma work together with FVB Sverige ab in order to come up with a program for short term planning of the production of heat and power at the company´s CHP-plant.The work consists of three main parts.

"In i sagans land" : Aktionsforskning i bibliotekspraktiken med syfte att utveckla sagostunden

The purpose of this master's thesis is to examine children's communication and interaction during story time at the public library. The aim is also to examine how to develop the story time ? in terms of participation and equality ? at a specific library.Action research was used as a research strategy and participant observation, log, tutoring and interviews as methods to collect data. Since action research is done on the basis of practice, a significant collaboration with the librarian and the participant children is taking place within this study.Research from the fields of Library and Information Science, Education and Childhood Sociology form the interdisciplinary research area to which this study links. The theoretical framework consists of theory and concepts from the Socio-cultural Perspective, Poststrucuralist Feminism and Childhood Sociology.

Strävan efter det legitima polisväsendet : En jämförande studie mellan tre postkonfliktländer

Products and services have for a long time competed with their brands. For some time now, cities have begun to compete with each other to attract visitors and other stakeholders to come to their town. It is important that the citizens feel as they are a part of the message that the city sends out in its communication.Cities are today working actively with their brands, much like regular companies, in order to create the profile and image in order to be competitive against other cities and places. Cities and places are part of a dynamic process which includes both positive and negative events. These events might have an impact on the brands, and therefore it is a necessity to be able to react on these events to make the most of positive things and deal with the negative in a way that minimizes the effects on the brand.Citybranding as a research field is quite new.

Swedish dairy farmers? interest in using price risk management tools : a study of correlating factors

The dairy market will change importantly in the coming years. The quota system, which has regulated the European dairy production, will disappear in 2015 and the European dairy market will then be importantly affected by the volatility characterizing the dynamic of world prices. Besides this, the global demand of dairy products is expected to increase due to the growing world population. Farmers in countries such as the U.S. and New Zealand, when compared to Swedish farmers, show greater familiarity and experience with risk management tools.

Bärförmågetillväxt i pålad friktionsjord

Piled friction soil show a set-up which is increasing with the time after installation. The cost could be reduced if the set-up had been taken into account when designing but in Sweden it is very unusual to do that. Previous studies showed that set-up can vary between 25 % and 75 % during the first 90 days after pile installation. This showed that the effect of the phenomenon is difficult to predict. A study involving five projects have been carried out by specifying certain parameters like pile type, method for pile installation and test method for measure the bearing capacity in friction soils located in Sweden.

Managing Positions in a Dynamic Environment - New Technology Impact on Tactel and the Telecom Industry

The Telecom industry is facing a paradigm shift, where the industry is converging with Internet technologies and the market is becoming more sophisticated. This results in more demanding customers, and the need for offering more content and services with a focus on usability for the end-users. The operators are starting to loose both their strong position and revenue in the Telecom industry, due to new technology and the fact that other actors are starting to enter the market, offering new content and services. In the end, the operators have two choices, to become bit-pipe providers, and only focusing on network management, or keeping the control over their networks. The latter would mean that they block other actors who are taking parts of their revenue, e.g.

Föränderliga stadsrum : flexibilitet, dynamik & interaktivitet

The number of inhabitants of the towns and city centers have generelly increased, concurrent as the population in smaller towns has decreased. In Stockholm, the migration is very fast and here is also the most populous place, if one compares with other Sweden. In order to respond to the increasing population and the pressure they put on city spaces has Stockholm's town a town building strategy that says "build inwards". It means that one stem seals the town with spaces and business activities in central locations. The increased population in the towns and the densification of buildings leads however to an increased pressure on parks and public places.

Stockholm temporary : relevancy & potentials for implementing temporary architecture in Stockholm

Temporary architecture is an alternative urban planning concept which has been adapted in many cities worldwide during the last decade. There is however no common definition for temporary architecture and it is diversely labelled and applied. In 2013 it also became publicly introduced in Stockholm via the approval of the city's first architectural guideline. Temporary architecture is presented in the guideline as a potential tool for exploring public spaces among other architecture related themes. The ideas for temporary architecture are ambitious and promising. The problem is that they are vague and leaves questions regarding performance unanswered.

Verifiering av beräknad energiprestanda för flerbostadshus byggda år 2007-2009

The building industry consumes approximately 40 % of the total energy consumption in Sweden, where the using stage is dominating with 80 %. There is a lot of work in progress to reduce energy use in the building industry, and the demands from authorities regarding energy use increases. As a part of this work Building and planning department of Sweden has established a requirement that has been applied since 2006, and restricts a maximum energy use for buildings.The requirement includes that an energy simulation must be done in advance to demonstrate that it is possible to meet the demands.Reality is however more complex than an energy simulation program, that frequently underestimates the energy use of buildings. The purpose of this thesisis to study and analyse deviations between estimated and actual energy use in modern apartment buildings. The study includes four apartment buildings in Stockholm, Gothenburg and Jönköping that were built in 2007-2009.
