Är OSSg2 ett lämpligt steg mot Open Source på verksamhetskritiska IT-system?
Sun Microsystems chose its own Open Source path by not following competitors in their commitment toGNU/Linux. Sun instead created its own Open Source project from the source of Solaris under the name ofOpenSolaris. The business model of OpenSolaris belongs to the new and more commercially viable OpenSource, referred to as OSSg2. This survey was based on articles on the adoption of Open Source in organizationsand István Orci?s publication Kritiska IT-System.
Högskolestudenters uppfattning av informationsöverflöd: En studie med fenomenografisk ansats
With the volume and availability of information increasing as fast as technological development in society a phenomenon called information overload has emerged. The purpose of our thesis was to investigate how university students experience this increase in volume and ease in access to information. In our study we concentrated our focus on the student?s use of electronic resources. So as not to prejudice our study group our questions focused on different aspects of searching for information.
Energibolagens framtida datainsamling
The Swedish energy companies have several different systems for data collection of the energy consumption of their clients. Often computerized remote meter readers are put in practice in order to register the energy consumption of large companies. The majority of household clients, however, are read off by the assistance of manual methods. Household power consumption is read off once a year. As a result, these clients are not debited for their actual consumption; their invoices during the year are the result of estimations.
Bron och Attityderna : en undersökning av politiska åsikter kring Öresundsbron
This thesis deals with past and present political attitudes towards the Öresund bridge. It describes the decision making process which preceded the construction of the bridge, and has a short historical introduction to it. It then presents the attitudes towards the bridge of five different political parties, all represented by regional politicians. This empirical information was obtained through interviews with politicians and literature studies. The author then analyzes the empirical information with the help of the human ecological triangle developed by Steiner, and the center-periphery theories of Wallerstein and Persson.To conclude, the author describes what the central problem is in the case of the Öresund bridge from a human ecological perspective and analyzes the empirical data collected..
Community Supported Agriculture (CSA) - en väg mot ökad uthållighet? : en studie av Ramsjö gård
Over the past one hundred years, there has been an increasing globalization and
industrialization of the food systems. As a result, the distance between the production and the consumption of food has increased, both in time and space and in the minds of
people. There is also an increasing concern for the environmental effects of industrial
farming and the long distance transportation of food.
Sustainable agriculture and efforts to build more sustainable food systems has emerged in
opposition to the global food market. The definitions of sustainability usually include
environmental, social and economical aspects. To build more localized food systems is
seen as one way towards increased sustainability.
Agilt - men agilt nog?
This paper aims to investigate whether a small organization with small development teams can find a value in leaving a functioning development process to follow a formal systems development methodology, if these organizations can find support in an agile systems development method and in such case the method needs to be adjusted according to the organizations unique conditions.A traditional plan-driven system development methodology includes a number of phases that are carried out sequentially and a completed phase can basically not be resumed. All requirements are specified at the beginning of a project and at the end of the project only one delivery of software take place. This can cause difficulties in for example dealing with changing requirements. Agile system development methods intend to deal with changing requirements and to enable continuous delivery of valuable, working software.In this paper, both the traditional plan-driven methods and agile methods will be explained. Research methodology and existing system development theories will be discussed and a company where the study has been conducted will be presented.
Ickelinjär kurspåverkan vid kreditbetygsändring
Att bedöma och betygssätta företags kreditvärdighet är en stor och vinstbringande marknad. Ett företags kreditbetyg har visat sig ha stort inflytande när t ex lånevillkor behandlas. Detta ställer höga krav på kreditvärderingsföretagens förmåga att leverera korrekta analyser. Såväl långivare som investerare reagerar på ett ändrat kreditbetyg, vilket ger direkta effekter på det företag som betygssätts. Kreditvärderingsföretagen har kritiserats bland annat för att inte svara tillräckligt snabbt på ny information.
Informationskvalitet: informationssökares syn på kvalitet

However, the respondents are not aware of the strategies they are actually using. An explanation is the respondents lack of education in information seeking.
Att reducera lagernivån : en studie vid SKF Mekan AB
Background: The increasing competition on the market demand both companies and supply chains to find optimal solutions. The edeavour to reduce inventory levels is a part of this. Earlier, inventory was seen upon as valuable assets, but today they tend to be more and more negative in the eyes of the companies. Inventory demands capital, handling, and space. Therefore inventory creates unnecessary costs.
Ekonomistyrning i den svenska sjukvården: En utvärdering av KPP-systemet

This would facilitate evaluations and comparisons of the costs for certain diagnosis, patient groups or clinics with a different mix of diagnosis. The study investigates the following questions: 1. Does the KPP-model theoretically work as a cost accounting tool for health care purposes? 2.
Content Management Systems - effektiviserar informationshanteringen?
För ett par år sedan tog utvecklingen och fokuseringen kring Internet fart på
allvar ute bland företag. Alla skulle ha en webbsida och anledningen till detta
var ofta att konkurrenten hade en eller att man bara ville synas.
Idag finns det ett antal så kallade Content Management System utvecklade för
att hantera information på Internet, intranet och extranet. Det gemensamma för
dessa system är att användarna skall kunna uppdatera, vidareutveckla och
administrera lösningen utan någon teknisk kompetens.
Syftet med den här uppsatsen var att undersöka om ett Content Management System
effektiviserar uppdateringen av information, med hjälp av kategorier inom
användbarhet. Användbarhet består av flera olika kategorier, dock har vi valt
att begränsa oss till tre av dessa; effektivitet, syfte och tillfredsställelse.
För att få djupare kunskaper inom ämnet användbarhet har vi läst böcker och
artiklar, vi har även sökt information via Internet. Vi hittade information om
användbarhetstest där vi fann en metod som hette utredning.
I domstolens fälla? Den Liberala Intergovernmentalismen från Utstationeringsdirektivet till Lavaldomen
This thesis aim to advance the Liberal Integrovernmentalism (LIG) developed byAndrew Moravcsik in order to order to explain how the European Court of Justice (ECJ) can make de facto EU policies diverge from what was originally intended by the Member States. More specifically it describes how the Posting of Workers Directive, Directive 96/71/EC, originally was created to shield certain Member States and their respective systems of regulating the labour market from pressure arising from the posting of workers form low-wage countries inside the EU. However, through a series of cases in the ECJ the de facto policy of the directive has changed and it is now in itself a potential threat against these systems. The Member States now find themselves caught in a ?Joint-Decision Trap?, unable to rectify the situation even though their original agreement has been turned on its head.

This degree project is aiming to improve the situation for laying hens in cage-systems. The aim with our project is to bring forward a draft of a cage that improves the welfare of laying hens.
Visualisering ? ett verktyg för att illustrera långsiktiga konsekvenser av slutavverkning och naturhänsyn
Forestry in Sweden is currently conducted in a manner aiming at equating the production objectives and the biodiversity. To ensure that biodiversity is maintained, patches that are considered to be valuable now or in the future is saved in final fellings. How the tree retention areas will grow into the future forest stands is yet unknown.The purpose of this study was to visualize how different scenarios of natural consideration taken at final felling will evolve in a long term perspective, for two rotation periods. Projections of the forest conditions were executed with the decision support system Heureka and its applications PlanStart and PlanWise. The information about the projected forests was then used for the visualizations which were created in the software Visual Nature Studio.
Kyla i Nyköping och Motala : Kartläggning av kylapotential för Vattenfall Värm
The Swedish energy company Vattenfall is currently the owner of the district heatingsystems in Nyköping and Motala. To be able to also offer cooling solutions tocustomers are becoming more and more important. This report describes the resultsof an investigation of the cooling market in the two cities and the potential needs forcooling today and in the coming 20 years. The total potential for the coming 20 yearsis estimated to be roughly 17 MW for Nyköping and 9 MW for Motala.Two possible district cooling systems for each of the two city centers was modeledand a comparison was made between different cooling techniques namely absorptionand compressor chillers.Absorption chillers driven with district heating during the summer is one way ofincreasing the load in a combined heat and power plant and thereby the possibleelectricity generation. The cost of heat production must be low for absorption chillerto be able to compete as an alternative.
