Today there is an even higher demand on IT-projects success rate compared to a few years ago. IT-projects must be handled more efficiently and result in a more profitable investment. In order to make the handling of IT-projects more efficient and create profitability the developers must have a broad understanding of the IT-projects characteristics and which factors that affect the result of the projects. Changes within IT-projects are often carried out through the development of a system. Since this change is more common when it comes to IT-projects it is important to handle risk and change within these kinds of projects in order to prevent and avoid uncontrolled changes.

Världen är idag mer energiberoende än någonsin. I Sverige står bostads- och servicesektorn för 38 % av landets energianvändning. Till följd av det ökande beroendet av energi har EU infört nya direktiv när det kommer till nybyggnation och ombyggnad av fastigheter. Byggnaders klimatskal byggs allt tätare för att spara energi, vilket skapat problem med inomhusmiljön. Temperaturen inomhus blir ofta för hög i energieffektiva byggnader och byggnadsrelaterad ohälsa kan öka till följd av för dålig ventilation.Polhemsskolan i Gävle driver en butik i fastighet P5, där personalen upplever att inomhusmiljön är otillfredsställande.

During the last decade a number of studies have been published that investigate how the most fundamental aspect of political organization, the regime type, affects population health. The results unanimously show that citizens of democracies live longer and healthier lives than citizens of non-democracies. Many explanations for this have been suggested, among these are that democracies redistribute more and invest more in salutogenic resources, and that the tendency of dictatorships to control the media negatively affects the ability to spread information crucial to public health. When these mechanisms are controlled for, however, it turns out that democracy has a large residual correlation with for example life expectancy, which suggests that other mechanisms are also involved.In this paper two new mechanisms regarding the possible psychosocially mediated health effects of the regime type are investigated, namely political repression, and the possible negative effects this might have on the levels of chronic stress, and autonomy, which connects to a large previous literature in social epidemiology. In the paper an ecological cross-country design is used and country-level data, provided mainly by the World Bank and Freedom House, is analyzed with a simple multiple OLS-regression model.

Background: The construction industry is Sweden?s single most important industry branch with a significant influence on Sweden?s wealth. The political restrictions that once controlled the industry are today almost gone. This combined with an unbalanced supply and demand situation on the Swedish constructions market, caused by urbanisation, has led to increased pressure on the Swedish construction companies who now are forced to find new methods in their struggle to contain or increase their competitive advantage. Purpose: The purpose of this thesis is to survey: which strategic variables are of great importance in today?s Swedish construction industry with focus on the four main actors, JM, NCC, PEAB and Skanska.

This thesis describes how a cost reduction project was done on the Packsize ondemand packing machine EM7. The cost reduction was achieved by making minorredesigns of the EM7.The project began by studying the EM7´s structure and function by working on itsassembly line. A short literature study on the subject Design for Manufacturing wasalso done.By working on the assembly line and by speaking with staff from production anddevelopment departments, a number of ideas for reducing manufacturing costs arose.Estimations of the potential cost reduction size for each proposal were done incollaboration with vendors and the purchasing department. Based on the size of the cost reduction, technical risk, impact on the assembly lineand the development time the various proposals were ranked. The two highestranked proposals were selected for further development towards finished solutions.One of the ideas that were selected to develop in to a finished solution meant thatsome of the pneumatic valves were replaced with others.

Presentations of Oriental people as subordinated the West and their ideals was one way for Europeans to expand and keep control over their colonies in Africa during the nineteenth- and twentieth centuries. France and Great Britain controlled their colonies in different ways which has led to diverse legacies. Today, tourism is a source of revenue for former colonies, such as Tunisia and Kenya, and tourism also helps to spread knowledge and images of distant countries. A guidebook is one way that knowledge of other countries and people are spread to travelers. During history, images of distant people were based on a colonial discourse in which the west was seen as superior; but is that still the case? The purpose of this paper was to analyze how Tunisia and Kenya are presented in the Lonely Planet guide to Tunisia and the Lonely Planet guide to Kenya to investigate if they are constructed through a colonial discourse, and to see if there are any dissimilarities on how they are presented.

The aim of this Master's thesis is to examine difficulties concerning information acquisition, use, and management experienced by graduate students in physics during their first years of research work. Semi-structured, qualitative interviews were carried out with nine doctoral students. The theoretical background for analysis of the material is based on the work of Patrick Wilson, with particular focus on the concept of cognitive authority, and on that of Lars Seldén, who has proposed the idea of an information seeking career running parallel to the academic career of the researcher. Results from the interviews indicate that most of the students, in the early stages of their information seeking careers, rely to a great extent on supervisors and more experienced colleagues when identifying material needed for the research project. In a situation where information of potential relevance is abundant and where experience and focus are not yet fully developed, senior researchers function as cognitive authorities and as guides to other cognitive authorities.

I take interest in whether and how students in primary schools nowadays in Sweden participate in book clubs. My focus is on why teachers and school librarians choose to run book clubs and try to understand the structures that make book clubs possible. The method form my work is the qualitative research interview. I interviewed a group of eight people, five school librarians and three teachers from a medium-sized city in southern Sweden. My theoretical framework is a model contructed by researcher Patricia Montiel-Overall called Teacher- and Librarian Collaboration.

The company Bergteamet, Boliden, Sweden, is installing ventilation shafts of the Garpenberg mine. For such work a platform is needed which you can stand on and work from. The Shaft Reinforcement Team at Bergteamet performs the installation work and is the sponsor of the platform. The project described in this report is performed at the department MEC, Mining Equipment Construction, which has been given the task to design and construct the platform, customized for the current shaft. After this the platform is manufactured and inspected at the workshop at Bergteamet.The design work was carried out as follows:- After an initial meeting a requirement specification was worked out, describing the problem and previous experiences of platforms and requirements for the design and equipment.- A concept sketch was developed with consideration of surrounding factors.- A constructed 3D model was presented along with the choice of materials.

Tekniken inom energihushållning har utvecklats mycket de senaste 50 åren. Idag har vi en helt annan syn på uppvärmning och hushållning av energi i byggnader än vi hade då. Denna rapport kommer att fokusera på ventilation- och värmesystem eftersom dessa, tillsammans med isolering, har visat sig vara de viktigaste ur energihushållningssynpunkt.Det var egentligen efter oljekrisen i mitten på 70-talet som energihushållningsfrågan drog igång på allvar. Eftersom oljan blev dyrare så var man tvungen att hitta andra lösningar för att värma upp byggnader.Inomhusklimatet i bostäder, kontor, skolor och andra lokaler har en avgörande betydelse för människors hälsa och välbefinnande. Ändå har hälso- och komfortproblem med anknytning till inomhusklimatet varit ett stort problem.

The development in photogrammetry has created possibilities for new methods in aerial images acquisition. Remotely-controlled imaging from an unmanned helium zeppelin is a new and relatively unexplored acquisition. The purpose with this degree project is to evaluate the accuracy of this kind of low-height photographing system, a task given from the consultant company WSP, in Sweden. Landbadet in Uddevalla municipality was chosen as a test field for the zeppelin. Seventeen images distributed over three strips were acquired from the flying height of 80 m.

Kontorslokaler nyttjas generellt cirka 2500 av årets 8760 timmar. Ett vanligt problem med kontorslokaler är det termiska klimatet, antingen är det för varmt, för kallt, eller så drar det. Höga temperaturer, över ca 26°C, bidrar till trötthet, nedsatt koncentration och gör att luften känns mindre fräsch. Stora variationen av lasten mellan dag och nattetid kan också resultera i att lokalerna överventileras under nattetid och underventileras under dagtid.Syftet med examensarbetet var att undersöka och jämföra Ecoclimes komforttaks lösning med andra olika värme och kylsystem i kontorslokaler. Att undersöka vilka eventuella fördelar Ecoclimes komforttak har gällande komfort, kyla, ventilation och ur energisynpunkt.

Utmattningssyndrom är ett snabbt växande problem i vårt land, studierinom området har visat att detta tillstånd ofta är stressrelaterat. Stress är enreaktion på obalans mellan de belastningar som människan utsätts för ochde resurser som han/hon har för att hantera dessa belastningar. Att drabbasav utmattningssyndrom kan bl.a. innebära en minskad förmåga tillrörlighet, vilket också innebär svårigheter att klara det dagliga livetsaktiviteter. En av arbetsterapeutens uppgifter är att hjälpa patienter hitta enhälsosam balans mellan arbete, vila och fritid.

Med energieffektivisering menas att man använder energi på ett effektivt sätt som ska leda till en positiv inverkan på miljö och samhälle.Sisjö Entré är ett köpcentrum som har en årlig energiförbrukning på 1 865 270 kWh och bör enligt Energimyndighetens riktvärde ha en årlig förbrukning på 1 530 000 kWh, alltså en minskning med 18 %. Köpcentret består av 17 butiker och i examensarbetet undersöks fem butiker vilka är Toys ? Us, Rusta, Burger King, Babyproffsen och Webhallen. I dessa utförs mätningar på ventilation och belysning med syftet att studera vilka laster i butikerna som orsakar mest förbrukning. Målet är att komma fram till förslag på åtgärder för att minska energiförbrukning samt kostnader.Vi kom fram till att belysning är den största lasten i handelslokaler vilka är Toys ? Us, Rusta, Babyproffsen och Webhallen medan den största lasten i restauranger (Burger King) är utrustningen i köket som står för 75 % av restaurangens totala förbrukning.I Rusta upptäckte vi att elmätarna visade lägre värden än den verkliga förbrukningen.

Black nightshade (Solanum nigrum L.) is a major problem in gardenpea cultivations contracted by Findus AB, a Swedish food processing company. The main problem is that the nightshade berries contain solanin and, thus, are not tolerated in the marketed product, which is fresh frozen peas. In addition, berries have the same size and color as the peas and cannot be separated at the factory. Black nightshades have the last ten years become a more common weed in field grown vegetables in the southern parts of Sweden. This MSc thesis presents an experiment conducted in 2005, aiming at developing a tool for predicting the need for control of black nightshade in peas.
