Uppsatsen syftar till att undersöka former och frekvens av IKT i ett kommunikativt syfte i skolan.I bakgrunden presenteras att kommunikation med datorerna sätter sin prägel på människors liv och Internet påverkar i hög grad den dagliga tillvaron. Hur tillgången till datorer är i svenska hem och skola samt vilken betydelse datorns placering i har arbetssituationen belyses.I den teoretiska bakgrunden beskrivs vad kommunikation och information är, att vi alltid kommunicerar men det är skillnad på de medel som används. Här belyses även datorns betydelse för kommunikation inom informations- och kommunikationstekniken (IKT). Här exemplifieras vidare datorn i ett pedagogiskt syfte och dess användning inom skolan samt att kringmiljön är viktig.Studien är huvudsakligen baserad på en kvantitativ metodinriktning i form av en enkätundersökning där lärare och elever vid tre skolor i sex olika klasser svarar på frågor kring datorns nyttjande både inom skolan och i hemmet.Resultatet visar att både elever och lärare är frekventa användare av datorer och kommunicerar via IKT i olika former. Båda grupperna är positiva till att i ökad grad kommunicera via IKT.

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.

Today there are many system development projects that break both budget and time plan. Often this depends on defects in the information systems that could have been prevented. The cost of test can in some cases be as high as 50 % of the projects total cost and it's at the same time an important part of development. Test as such has moved its focus from the software it self and its faults to a wider perspective on whole infrastructures of information systems where assure a good quality is important. Sogeti in the Netherlands have developed a test method called TMap (Test Management approach) that can be used for structured testing of information systems.

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.

The purpose of this study is to increase knowledge and clarify how active educators regard ICT- tools as aids, both the educators currently using the ICT- tools to improve writing skills and educators who have not yet embraced it. The study is based on four interviews with educators working within the age groups grade 1- 3. The findings of this study show a strong commitment among all educators, in terms of students' writing skills and their different approaches to working with writing skills, which is important as one method should not preclude another. In the findings a considerable curiosity can be seen for ICT- tools for writing instruction by the educators who have not embraced it. The interest and commitment of the educators who have embraced ICT- tools in their teaching is great..

The amount of information stored on the internet grows daily and naturally the requirements on the systems used to search for and analyse information increases. As a part in meeting the raised requirements this study investigates if it is possible for a automatised text analysis system to distinguish certain groups and categories of words in a text, and more specifically investigate if it is possible to distinguish words with a high information value from words with a low information value. This is important to enable optimizations of systems for global surveillance and information retrieval. The study is carried out using word spaces, which are often used in text analysis to model language. The distributional character of certain categories of words is examined by studying the intrinsic dimensionality of the space, locally around different words.

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.

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.

Studiens syfte var att undersöka varför de lärare i grundskolan och i gymnasieskolan som använder datorn använder den och de som inte använder den undviker den, och vilka för- och nackdelar de ser med datorn i undervisningen. Det empiriska underlaget består av fyra intervjuer av lärare på två gymnasieskolor och en grundskola. Resultatet visar att lärarna inte såg sin egen datorkompetens som något hinder för undervisningen, däremot ansåg flera av dem att de inte kände till vilka program som kunde användas. Lärarna såg datorn som något positivt för matematikundervisningen, men såg även en oro för att eleverna inte lär sig grundfärdigheterna i matematik. Slutsatser som kan dras är att det behövs mer kunskap om hur datorn ska användas i matematikundervisningen och att det behövs förhållningsregler till det ökade antalet datorer i skolvärlden..

This thesis analyses the cost accounting system KPP and its use within the Swedish health care. KPP is designed to calculate and assign health care costs to individual patients. 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.

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 study was carried out in Jordan with the purpose to investigate the bacterial microflora of egg shells from cage systems and from deep litter floor systems. Another aim wasto get a general impression of the hygiene, at farm level, of egg production in Jordan andthe factors affecting it.Eggs from two cage systems and three floor systems were analyzed, regarding bacterialcontamination of the egg shells. Egg samples were taken from the storage room, the eggcradle in the cage system and from the nest and floor in the floor system. To get a generalimpression of the hygiene at the farms, swab tests and air tests were performed. Swab testswere performed with a sterile cotton swab at the same units as the eggs were sampled andair tests were performed by opening petri dishes where the hens were staying.

Today?s housing system for laying hens has limitations for the hens natural behavior. Despite the current law of prevention of cruelty to animals, this might implicate health problems for the hens. 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.

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.
