Att gestalta en socialt hållbar begravningsplats
This thesis aims to present the essential background on how to perform climate changeimpact assessments, and to present the results from a climate impact assessment on waterbalance and nitrate leaching for an arable Swedish soil. The soil is a sandy soil in southwesternSweden, grown with spring cereals. This study is meant to be a benchmark example,and cannot be seen as a regional or national assessment for Sweden, rather as an approachto present and analyze the most important parts of these kinds of assessments.A dynamical simulation model (COUP, Jansson and Karlberg, 2004) was used for thisstudy. The model was parameterized and calibrated against data from an experimental site,located in Mellby in Hallands county, south western Sweden. Measurements were carriedout between 1st of April 1988 and 1st of April 1991.
Att se med barns ögon ? en undersökning om förändringsarbete på barnbibliotek
The purpose of this Master´s thesis is to examine howchildren?s needs, based on the Convention on the Rights ofthe Child, are provided for by the librarians when they havethe opportunity to create new libraries. We also examine ifchildren have been involved in the process and in that case towhat extent.Our theoretical perspective is based on MarianneAndersson?s and Dorte Skot-Hansen?s model of the fourdifferent functions the library can have for their users. Inorder to illustrate the degree of children?s involvement weuse Roger Hart?s model of participation.The thesis is based on qualitative interviews with seveninformants working at six different libraries.As a result of the thesis we can see that priority have beengiven to the function concerning how to find your way in thelibrary as a user.
Lönediskriminering av invandrare: en empirisk undersökning av invandrares samt invandrarkvinnors förhållanden på den svenska arbetsmarknaden 2005.
I denna uppsats undersöker vi huruvida invandrare diskrimineras på den svenska arbetsmarknaden. Vi undersöker även om förhållandet skiljer sig när vi endast tittar på gruppen kvinnor, och gör en jämförelse mellan svenskfödda kvinnor och invandrarkvinnor. Vi använder oss av två modeller för att estimera löneskillnader, dummyvariabel modellen och Blinder-Oaxaca modellen. Våra resultat ger tydliga indikationer på lönediskriminering gentemot invandrare, kvinnor och en ännu tydligare lönediskriminering gentemot invandrarkvinnor. Vi anser att invandrarkvinnor drabbas av en så kallad dubbel diskriminering, där den övriga populationen i genomsnitt ges 28,4% högre lön än invandrarkvinnor..
The importance of shade for dairy cattle in Sweden.
Today, there are no regulations saying that cows must have access to some kind of shelter at pasture during the summer. In more tropical countries, it is well-known that dairy cows might suffer from heat stress when exposed to sun and high temperatures. The well-being of the cows is thereby reduced and the production may also decrease. In Sweden, no research has been done in the area and therefore it is now a clear need of improved knowledge.The purpose of this study was to investigate the importance of shade for dairy cows in Sweden. The behaviour of 30 cows was examined to see any differences between cows with access to shade and cows without access to shade.
Kommunal demokrati och medborgarinflytande i ett samhälle i förändring
The organisation of the municipalities is based on the principle of representation. It has previously been impossible to give the citizens more influence through direct democracy, but the information technology gives new possibilities and the choice of democracy model might no longer be obvious. Representation can be interpreted in many ways and there is a need for a more distinct definition of the rule that the municipalities shall be governed according to the principle of representation. It should also be further investigated how the new technology can be used to increase the use of direct democracy. The municipalities ought to work to supplement the representation with direct democracy in the form of active discourse with the citizens.
Konkurrensfördelar på en marknad som karaktäriseras av offentlig upphandling
Background: It is necessary for a company to hold some unique and irreplicable competitive advantage in order to be able to succeed in a market. In a market where public procurement is an important part the competitive advantages will be characterized by the fact that some of the participants on the market are public organizations and that their actions as for procurement fall under the legislation LOU. The characteristics of competitive advantage also depend on and change with continuous changes on a market. Purpose: The purpose of this thesis is to study the competitive advantages that are presenton a current market characterized by public procurement and how these are created. The purposes is also to based on the trends on the market today study and predict the nature of the competitive advantage on the market in the future as well as the changes that we think will occur on the relevant market.
Småskalig biobränsleeldad kraftvärmeproduktion : teknik och investeringsutrymme
To achieve the requirements to decrease emissions of greenhouse gases by 20 % by 2020, Swedenneeds to increase its use of bioenergy. In doing so it seems natural that those who already haveaccess to large amounts of biofuels in the form of by-products such as straw, wood chips anddigestible materials take advantage of these assets locally. By combining production of heat withpower production at the farm it may be possible to not only reduce the direct use of fossil fuel forheating but also reduce energy costs.The purpose was to simulate different cases of using a small scale biofueled combined heat andpower plant for farm-based systems. A MatLab-model was developed and used to draw conclusionsabout the costs for production of heat and electricity with different conversion technologies.The model uses climate data to simulate the variations in heat energy demand on a day-to-day basis.The given heat demand is the base of the simulation and from this the possible electric output iscalculated. This study has focused on the impact of the following properties: electric-, heat- andtotal efficiency, fuel, fuel price and specific fuel requirements.
Boken kommer: förmedling och bemötande.
My aim is to examine the special form of interaction between users of the shut-in service and the responsible librarians. My purpose is to examine how mediating of literature can be pictured in correlation with shut-in services. How do librarians describe their experiences of the shut-in service? What roles of mediating can be perceived? How can interaction interpreted in the context of the shut-in service?The material was acquired by doing qualitative interviews of five librarians who works with shut-in service. This study is based on the theory of Åse Kristine Tveit.
Salutogenes - grunden för skolsköterskans hälsopromotiva arbete inom området barn med fetma :
Abstract Background: The World Health Organization has expressed a great concern about the increasing prevalence of childhood obesity. Region Västra Götaland (VGR) has developed a web based program to support school nurses in their work to promote health among children with obesity. Previous research on childhood obesity emphasizes the importance of support from nurses and how their work is organized. Aim: The aim of the study is, firstly, to explore school nurses experiences with health promotion work among obese children. Secondly, to investigate whether school nurses use the salutogenic theory of health.
Sätter jag mig i ett hörn, blir jag äldre än vad jag är : En kvalitativ studie om insatsen aktivering inom hemtjänsten
From the day we are born, we slowly grow old and sooner or later most people will have to use geriatric care provided by the community. In the Swedish model, society is responsible for the geriatric care, so the elderly can live a dignified, meaningful and active life. Home help insert activity is designed to help elderly get their social needs satisfied in the form of, for example, being outdoors, walk and visit a friend or some other form of social interaction. The study's purpose is to study how older people use and perceive bet activation in the municipal home care. To find out how this was conducted five interviews with older people who have help from home care to insert activation was made.
Revisionsutskott i svenska aktiebolag: En statistisk analys
The recent development in several countries? legislation and best practice recommendations in relation to corporate governance in general and audit committees in particular have affected Swedish listed corporations in the form of the Swedish Corporate Governance Code and the coming EU-directive. This paper aims to discover what factors affected Swedish listed companies to form audit committees when this was entirely voluntary. We collected data from the annual reports of 121 Swedish listed companies and formed eleven hypotheses as to what factors we believed affected the voluntary formation of audit committees based on Agency Theory, economies of scale and circumstances specific to the Swedish environment. We then analyzed the data through the use of a multivariate logistic regression model.
3D-visualisering i markprojekteringsprocessen
The thesis has been made for NCC Teknik in Gothenburg. The NCC Corporation is one of the largest leading companies in Scandinavia within the construction industry. NCC is active throughout the whole construction process, where one part is to carry out soil investigations prior the construction of various buildings, for example residential buildings. NCC Technology wants to visualize the samples taken at the construction sites in 3D for clients, authorities and also internally to show in a simple and understandable way how contamination is spread out in the soil.The thesis includes the area of Limhamns läge in Malmö, previously an industrial area. The area has previously included a concrete factory and the contamination from that factory has lingered in the soil.
Energianvändning för markkonstruktioner förlagda med ytvärme : En teknisk och ekonomisk utredning av fördelarna med att isolera under värmerören
The need for snow-free surfaces at squares, bus stops, platforms, car parks and sports facilities increases and at the same time energy price rise and the environment is becoming a hotter issue. The construction of the ground heating systems often lack thermal insulation under the heating pipes, which means that the heat from the pipes not only warm up the soil surface but also heats the surrounding soil. The insulation also has more features, by insulating the risk of frost damage is minimized. The goal of this report is to demonstrate the large heat loss and energy costs in the absence of insulation under the heating system.The report begins with a scientific way to study and treating the soil heating system uses, and the theory involved. Furthermore it also deals with different routing principles of heat pipes depending on the facility.All calculations are made with so called finite element method (FEM), in COMSOL Multiphysics 3,5a, where models are created with different conditions.
Kommunala kulturmiljöprogram : strategiska planeringsunderlag för landskapsanalys, kulturhistorisk värdering och utveckling av kulturmiljöer
In 1999 the Swedish Parliament decided about 15 environmental goals aimed to be achieved in time for the next generation. For example physical social planning must be based on programs and strategies how cultural-historical values has been attended, so called programs of cultural heritage. By law the Swedish municipalities are responsible for reaching these goals by creating program of cultural heritage. But only a few of the municipalities have these programs, meaning that many municipalities need to create programs of cultural heritage in the next five years.The aim of this report is to present a model of analysis on programs of cultural heritage in municipalities for preservation and development of cultural environments. By testing the model on the municipalities of Osby and Tomelilla methods on how to create a new program of cultural heritage or how to complete existing documents are formulated.One of the conclusions is that one document, program of cultural heritage, functions as landscape analysis, model of cultural valuation and strategy of developing cultural values.
Beräkningsmodell för massbalanser för Slottshagens reningsverk
In the next few years the pollutants loading at the Slottshagen wastewater treatment plant in Norrköping is going to increase due to the reason that one of the waste water treatment plant in the district will be shut down.A survey of how these different pollutants are divided in the treatment process is therefore necessary for mapping out both the loading and treatment efficiency.This can be achieved by studying mass balances.Mass balances were carried out for the water treatment process for the mechanical/chemical,biological and the chemical stage.The mass balance studies show that the treatment efficiency was very good. However in order for the mass balances to be quite consistent and to ensure complete coverage of results and conclusions i.e. more reliable results, sludge samples should be collected and taken at different times per day and the influent rate should be investigated.In this work mass balance has been set up in order to illustrate and identify the factors that should be considered and taken care of for further estimation using mass balances in the future. Furthermore this survey results in a calculating model for the mass balances at thisplant.This calculating model is used as a tool to facilitate future calculations for mass balances for the water treatment process at Slottshagens wastewater treatment plant.Moreover it provides a basis for carrying out further estimation of the treatment process in the near future.In this project the importance of some operating parameters was also taken in consideration.This calculating model can be modified so that calculations of such operating parameters i.e. sludge loading and sludge age can be easily performed.Such information can be used further to evaluate different operation alternative in order to ensure an optimal use of the treatment process with in the plant..
