SummaryAimThe study examines a theoretical model developed to capture cyclist´s perceptions of the route environment. The survey focuses on if level two and three in the theoretical model captures what it´s intended to do. More specific we ask ourselves how the three appraisals (unsafe/safe by traffic reasons, stimulating/inhibiting route environment, unsafe/safe by other reasons) in the model´s second level relates among themselves and if these three appraisals can capture the degree of environmental well-being/unwell-being in the model´s third level. The questions were: Do the three appraisals differ among themselves? What is the difference/-s in such cases? And, is there a correlation between any of the three appraisals and environmental unwell-being/well-being? What is the correlation in such case? MethodThe gathering of data was done through questionnaires.

Open access (OA) is a publishing model aimed at increasingthe access to academic research results. The object of thisstudy was to contrast nine colleges and four fundingorganizations in Scandinavia with mandatory OA-policies,and to study how they put OA into practice.Inspired by the Open Access Spectrum (OAS), a tool used toappreciate the OA of academic journals, the aim was tograde the policy documents of the colleges using the OASmodel.The study also compares how the colleges implementtheir OA-policies as well as how, and if, the demands fromthe funding organizations are reflected in the policies of thecolleges.The findings show that the OAS is not a tool designed forgreen OA and that all the information needed for the scale tofunction was not found in the policy documents we studied.A selection of the colleges has some demands in theirpolicies, although most of them allow exceptions to be madefrom the mandatory policy. This is shown to be mainly aquestion of academic freedom, and copyright, or rather thanthe degree to which the scientist and the publisher can cometo an agreement on allowing the information to be accessiblethrough OA.The study proposes that the way to change this may be toincrease the demands on OA in the policies, and that the bestsolution might be in stipulations within the employmentcontracts between the individual colleges and scientist..

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.

Denna uppsats handlar om tektologi, en systemteori utvecklad av en rysk vetenskapsman vid namn Alexander Bogdanov mellan åren 1912 och 1928. Vi har i uppsatsen haft för avsikt att utreda om tektologin har något att tillföra modernt systemtänkande. Detta har vi gjort genom att låta Stafford Beers viable system model representera det moderna systemtänkandet, och därefter jämföra en modellering av en organisation med VSM, med en modellering av samma organisation med en egenutvecklad modell baserad på tektologi. Resultaten visar att tektologin har en hel del att tillföra modernt systemtänkande. Framför allt ger den nya infallsvinklar till modelleringen och belyser delar av organisationen som man inte kan se med VSM.

This study is about to see whether the two models representing the strategies of lean production is to use and apply in different companies. The models are structured in two different ways in which one of them is checking the softer elements of lean production in the form of leadership and strategies. This model is called Lesat and is based on interviewquestions. The second model, called "learning to see" is about identifying flows. This, together shall then give an idea of how mature companies are when it comes to a whole in the concept of lean production, and susceptibility to use these models to their respective companies. The study is conducted in two companies, SKF couplings systems and AQ parkoprint.

The purpose of this thesis was to investigate whether accounting quality is a priced factor by investors. The event studied is the release of year-end result and the release of the annual report. To assess accounting quality a sample of 30 companies listed on the Stockholm Stock Exchange during 2003 to 2007 are studied. We assess accounting quality by the absolute size of discretionary accruals using the modified Jones model developed by Dechow et al. (1995).

Background - Swedish trade and industry primarily involves small corporations, including small manufacturing corporations. Currently, most costing models that are used are based on studies accomplished at large corporations. This conveys to the fact that product costing that occurs at small manufacturing corporations is based on all complexities that large corporations bring, which rarely match with small corporations. It occurs that small manufacturing corporations unconsciously rely on incorrect information that has been calculated based on great corporations? product costing.

The use and attention given to the certification system ?Miljöbyggnad? has increasedin recent years. The system is completely Swedish and was initiated in 2005 by theBygga-Bo-Dialogen. Miljöbyggnad aims to create a healthy indoor environment, reduceenergy consumption and discourage the use of hazardous chemical substances. Thegrades that can be obtained are Classified, Brons, Silver and finally Gold.The work has been to examine three different models and conclude how the designof the models affect the grades in the certification system Miljöbyggnad.

During the last decades the housing sector has increased continuously, and housings and services accounted for 40 % of the energy usage in Sweden during 2011. The expansion in number of buildings in society has resulted in an increase in both energy usage and emissions of greenhouse gases. It is crucial to enable a sustainable development of society and as a result, the demand to reduce the emissions of carbon dioxide is a current question. In this study, the carbon dioxide emitted from the housing sector in Stockholm is estimated. The housing sector can be divided into different types of houses such as apartment blocks, single-family houses and holiday houses. By collecting information of the energy purchased in respective households, a computational model is generated that calculates the total emission of carbon dioxide.

Our purpose was to shed light on how parents act in respect of providing alcohol to young people when they ask for a taste of home, or wish to bring alcohol to such a party. We used qualitative interviews and the results show that some of the respondents think that it may be acceptable to provide alcohol, while some do not. The results also show that the respondents think that parents are important as a model for the young. They could not purchase alcohol for the purpose of giving it to the young but only if alcohol is available at home. The reason for this behavior is the parents' assessment that the young person demonstrates a level of maturity for his age that they are presumed to be able to handle a small amount of alcohol.

The aim of this literature review was to describe how the literature presents parents? need for information and how parents perceive the information from care personnel when their child 0-18 years of age is diagnosed with diabetes. The literature search was performed in the databases PubMed and Cinahl. Thirteen articles that met the inclusion criteria were studied. The results showed that when a child is diagnosed with diabetes the whole family faces a new situation and the parents are in great need for adequate information from care personnel to be able to deal with the new life situation and participate in the care.

Saab Aerosystems has a long tradition and a lot of competence in the field of flight simulation. Their ambition to broaden the market horizon has led to a discussion about also selling vehicle simulation solutions, both for military and civilian use.The aim of this thesis is to investigate the driver?s experiences of the accelerations he or she is exposed to whilst driving in rough terrain. The results may be used as a basis for future decisions and can act as a platform for the construction of an effective simulation model.To investigate the driver?s exposure of acceleration, some kind of dynamic simulation is needed.

Cycling is one of the most sustainable transport modes available and it is widely promoted inmany urban areas. The health benefits from cycling has shown to be substantial, includingdecreased risks of diseases related to overweight and enhancing brain capacity. However, inurban areas cyclists can temporaly be exposed to high levels of air pollution, resulting inhealth risks as opposed to health benefits.The objective of this thesis is to develop a rasterbased test model in GIS that estimates theinhaled dose of air pollution for cyclists based on relative particle concentration in differenttransportation micro-environments. The method used is a least-cost path approach,calculating three different routes; shortest, fastest and least dose for four different trips withinSödermalm, Stockholm.The results show that the inhaled particle dose can be greatly reduced, 39% - 58% for three ofthe routes, by choosing the least dose route. One of the most interesting findings is thesubstantial increase of dose when high levels of particles are combined with uphill cycling.The conclusion for the thesis is that a raster-GIS model can be very useful for estimating doseof different air pollution particles and chemicals along cycling routes.
