The aim of this study was to examine if performance-based self-esteem, personality (Type A), perceived stress, age and gender predict the value of own or others life-stress (VLS). The aim was also to examine whether the variables were correlated significantly with each other. The investigation was conducted in a town in the mid-south of Sweden. The instrument consisted of two forms where the first measured Type A personality and the second tapped perform-ance-based self-esteem, perceived stress and the level of life-stress. The results showed that the level of life-stress could explain, on the basis of the predictors, performance-based self-esteem, personality (Type A), perceived stress, age and gender.

The Swedish potential of electricity production from roof mounted solar panels has been determined in three steps: accessing the existing roof top areas, simulating the amount of electricity solar panels can produce on these areas and finally analyzing how large the necessary economical change is to make the solar cells profitable.The total existing amount of roof top areas are 319 square kilometers and the area distribution follows the distribution of people. This leads to an installed power of 47,9 GW which are expected to produce 49,0 TWh electricity per year. If the quality of the electricity is prioritized the highest the power is reduced to 3,7 GW, generating 3,8 TWh yearly, but if the hosting capacity is calculated from Sweden?s total electricity need, the capacity is 42 TWh per year.Today, solar panels are not profitable in Sweden for houses, even though there is a subsidy of 35 % of the investment costs, discounted in 25 years. The profitability is calculated with a cost of capital of 5 %, a price on electricity of 1 SEK/kWh and an investment cost of 20 SEK/Wp.

A clean and affordable energy source for cooking is deficient in developing countries. People rely on fuels that contribute to environmental, social and health problems.Biogas is an alternative energy source and an increased investment in small-scale biogas production can in several developing countries be found. Several projects have started to use the technology in developing countries because of the benefits with biogas. Some cases in the establishment of biogas plants have succeeded and some have not. The study is a literature review supplemented by two field studies.

Choosing a new plastic material for a container includes several different steps. In this case,the Finnish company Hackman needed a new type of packaging material for theircutlery- and kitchentool series »Hackman tools«. The project was carried out in cooperationwith the design agency Ytterborn & Fuentes, which has Hackman as a client.Several different demands were put on the material in order to fulfill as many of the clientswishes as possible. The most urgent problem with the existing container was the difficultysfor the customer to clearly see the contents in the container. Because of this problemthe customer tried to open the container in the shop.

This thesis is about new technology in academic libraries in the form of Patron Driven Acquisition. As libraries take part in the digital era, a new model of patron driven acquisition has emerged. This model gives users more influence over the libraries electronic book collection. The collection development model changes libraries traditional role in the collection development process, from collecting for the future to the present.The purpose of this thesis is to gain knowledge of what acquisition librarians think about the effects of PDA on the collection, the acquisitions role and the cost structure. The theoretical framework relies on Christensen?s theory about disruptive technology and was used to interpret outcomes of new technology in libraries and its staff.Five librarians from four different Swedish university libraries were interviewed using a qualitative semi-structured method to carry out the investigative part of this thesis.

This report presents an investment calculation based on an assumed initial investment of a new saw line to an existing sawmill. In order to get as close to reality as possible, we have received data material from northern forest owners who recently made an initial investment in their sawmill in Kåge. In order to calculate and evaluate investments are several different methods, but we, we have chosen to use the discounted cash flow method. The method sums up with the help of a fixed cost of capital together with any future costs and revenues, thereby giving a present value of the investment. We also do a sensitivity analysis to examine how selected factors affect the investment research they change. The study is carried out to a fictitious investment, and therefore the result should not only be studied as a result of the figures. The purpose of this study was that with the help of an investment calculation studying the profitability of a hypothetical investment, and by means of a sensitivity analysis to study the sensitivity of investment to changes. The result demonstrates that the calculations according to the present value method requires a lot of information of the prospective investment.

This thesis investigates the socio- and environmental economic effects of a deep repository for spent nuclear fuel in Forsmark in the municipality of Östhammar. I seek to show the general picture but focus on the effects on employment, environment and income. Cost-benefit analysis is used to investigate the differences in utility between a scenario with and a scenario without a deep repository in Forsmark. Most of the possible effects can not be valued and many can not even be quantified with the data available today. Therefore this thesis has a bit of a ?preliminary study character? and seeks to show what we know today and what needs to be further investigated when available data allow it. The costs that could be valued are noise from the traffic during the period of building and emissions of carbon dioxide and nitrogen oxides from the transportation of rock masses during the building period.

Projektet Precious utforskar narrativa lagningar av artefakter. I arbetet diskuteras människans komplexa förhållande till artefakter. Komplexiteten som behandlas i arbetet är fokuserad kring att artefakter förutom rent praktiska funktioner; även fungerar som verktyg i den sociala interaktionen människor emellan. Industrialism i kombination med bland annat den fria marknadsekonomin har särskilt efter Andra Världskriget bringat välfärd och accelererande konsumtionstempo i det moderna västsamhället. Konsumtionsvanorna är numera mer sammanlänkade med varumärken och social status än behovet av praktisk funktion.

Uppsatsen utreder ifall det finns en möjlighet till kostnadsbesparingar genom att erbjuda en stor andel av den äldre befolkningen hjälpmedel. Dessa hjälpmedel är tänkta att ha i förebyggande syfte för att minska antalet höftfrakturer. Perspektivet för analysen är samhällsekonomiskt, det vill säga alla möjligheter till kostnadsbesparingar antas tillkomma samma aktör. En uppdelning mellan landsting och kommun görs med andra ord inte. I en cost-benefit kalkyl görs en uträkning på vilken nettoeffekt som uppnås på den samhälleliga välfärden genom att antalet höftfrakturer minskar.En makroundersökning ligger till grund för de hjälpmedel som studeras.

The purpose of this master thesis is to investigate different types of measures for making buildings more energy efficient and to estimate their profitability. The calculations were performed with the building simulation program VIP+ and the evaluation of the profitability with the life cycle cost method. Furthermore, it was examined how losses in the distribution of secondary systems of district heating can be avoided. Options to replace district heating with a local district heating system based on bio-energy have been investigated. The possibilities of achieving more efficient thermal energy consumption and production for the chosen estate were also examined.The object of the study has been a residential estate with 133 detached houses in Uppsala, built in 1974.

This investigation?s task was to map manufacturing of special qualities at Stora Enso Packaging under a certain period, analyze if rules concerning special qualities is followed, which consequences this results in concerning use of paper, waste and costs and to give suggestions on alternative solutions. The goal was to give sugges-tions that help the company to reach its business ratio that the production de-partment uses within use of paper and productivity in the corrugated cardboard machine.Stora Enso Packaging is a part of the forest group Stora Enso and is one of Swe-den?s leading producers of corrugated cardboard. Stora Enso Packaging acts pri-mary on the Swedish market, where they have a market share of 25 %.To be able to analyze orders with special qualities we did a data collection during two months, where we mapped incoming orders.

In Uppsala, Sweden, Vattenfall has a combined heat and power plant. On the premises there is an engineering workshop with old fluorescent and mercury lamps that need to be replaced. This provides a great opportunity to save energy and money by installing more efficient lighting. The main purpose of this study was to present two functional and energy efficient lighting systems including control system. The lighting systems were designed by investigating the working environment, measuring illuminance and by simulations in the software DIALux.

Syftet med detta arbete är att studera de samhällsekonomiska konsekvenser som en uppstart av persontåg på TGOJ-banan, mellan Oxelösund och Eskilstuna, skulle innebära. På vägen fram för att uppfylla syftet med uppsatsen har ett antal frågeställningar pekat ut vägen och hjälpt till att föra in arbetet mot specifika problemområden. - Vilka kostnader är förenade med tågtrafiken jämfört med busstrafiken? - Vilken nytta uppkommer vid tågtrafik jämfört med busstrafik? - Hur stora är kostnaderna för järnvägen i förhållande till de uppkomna nyttorna? Ett väsentligt led i studien har varit att studera dagens resande för att kunna dra slutsatser om det framtida resande vid en uppstart av tågtrafik på sträckningen. Dagens kollektivtrafik resande, dagens resande på vägar i korridoren och resvaneundersökningar har varit faktorer som vägts in för att få fram det estimerade resandet.

In this essay, I have examined what has been studied and presented in the theory of ICT in schools. I have based my theory on Arne Trageton?s book Att skriva sig till läsning ? IKT i förskoleklass och skola (2005) and theories on children?s reading and writing development.The purpose of this study is to determine how teachers and children experience teaching with Trageton?s ICT-based model Att skriva sig till läsning and whether the model is beneficial for children's first reading and writing.Through qualitative interviews with two pedagogues from the same school and some children from first grade, I have received answers to my two questions:How do pedagogues and children experience ICT-based teaching in the context of children's first reading and writing?How do pedagogues experience the reading and writing development in first- and second-language students when using ICT-based teaching?The results showed that both pedagogues and children were positive about the model in which the computer was used as a writing tool in learning to read and write. The teachers felt that the model was suitable for all children according to their conditions.The children saw the writing as very enjoyable. For the ICT-based teaching to work properly, the technology has great significance.
