Lärares syn på teknikämnet. : En enkätstudie av pedagogers tankar kring teknik på mellanstadiet
Syftet med denna studie är att få en inblick i hur lärare på mellanstadiet arbetar med teknikämnet i skolan. Detta görs genom en enkät, vars frågor är upplagda efter tre frågeställningar: Vilka tankar har lärarna om teknik? Hur ser pedagogernas teknikundervisning ut? Vilket undervisningsmaterial använder lärarna sig av i teknikämnet? Totalt är det 65 lärare som arbetar eller har arbetat med teknik på mellanstadiet som deltagit i studien. Enkäten har visat på att de flesta lärarna som deltagit tycker att teknikämnet är ett roligt, spännande och intressant ämne som dock är svår bedömt, tids- och materialkrävande. Undersökningen visar även att de flesta lärarna tycker det är bäst att arbeta med teori och praktik varvat, då båda delarna behövs för att eleverna skall förstå teknikens innebörd i samhället.
Modelering av Wideband : Code Division Multiple Access
Today wireless transmission of data is becoming more and more popular and the need for faster transmission rates is increasing. Since the bandwidth is limited it is important to try to use it to the fullest. CDMA is a technology that allows multiple accesses on the same frequency and time thus making it very bandwidth efficient. The CDMA technology was first introduced in the second generation?s cellular systems but has since then been improved and is reused in today?s 3G systems as Wideband CDMA.

Strategic environmental management in a service organization : a case study of Swedbank
During the past decade environmental challenges have been intensified and given increased attention. This implies that businesses in all sectors strategically need to manage these challenges. The service sector is often considered as a sector with a low environmental impact if the direct environmental aspects are assessed. Still, it has been argued that the environmental impact that the sector gives rise to can create severe indirect environmental
impacts. The products and services that are produced by this sector have a relatively limited use of physical resources which may make the environmental impact challenging to visualize.
Banks belong to the service sector and it is partly banks that make the development of societies possible.
Open access i forskningspolitiken : en undersökning av de politiska argumenten i debatten kring vetenskaplig publicering
This Master's thesis aims at pinpointing the political arguments that appear in the recent debate on scientific publication. There is a widely spread opinion that prices on digital resources are far too high, thus taking up a major part of the University libraries budget, while publishing companies make high profits. It is also a common opinion that the current publishing method does not take full advantage of the possibilities of electronic publishing. Lately a number of alternative ways of publishing have been initiated and discussed, generally referred to as open access. Open access published material is available free of charge and free of most copyright and licensing restrictions on the public internet.In this thesis the minutes from four hearings held by the UK House of Commons in the spring of 2004 are examined.

Experimentell undersökning av provkroppar för trälimfogar
This thesis engages the topic of test methods for wood adhesives. Two test methods were evaluated, EN 302-1, a European standard, and ASTM D905, an American standard. The total amount of specimens manufactured and tested was more than 500. The adhesive bonds were tested in shear with an increasing load on the specimen until failure.The adhesives used were epoxy-resin, phenol-resorcinol-formaldehyde and a 2-K polyurethane. The test programme included five different types of intentional errors per method, in order to investigate the sensitivity of the test methods.
Vårt liv, vår fritid, våra förebilder, vår framtid och där vi bor
Few studies enlighten the problem associated with the dialectical relationship between adults and adolescents and how that affects the construction of identity for adolescent?s, in relation to two areas that are closely bordering to each other but differs socioeconomically whereas one area is much weaker on resources than the other. These two areas is Högberget and Haganäs, which are situated in a larger city in Sweden.For us to be able to enlighten this problem we have chosen to use an inductive research approach so that we can explain how adolescents construct their identity and how the organized spare time, in addition with the influence of adults, impacts on adolescents construction of their identity.Therefore we have used interviews as method, both group and individual, so it can regulate which theories that influence our study. The two theories that wires through the entire study are firstly Peter L. Bergman and Thomas Luckmanns theory on social construction where the idea is that the human being is an active social being that constructs its own reality.

Och längtan efter färg Del 2
This thesis examines the verification of the terms and conditions stated in contracts based on the Public Procurement Act. In March 2013 the Swedish state procurement commission released " Good Business - A Strategy for Sustainable Public Procurement " (SOU 2013:12), which found that the proportion of control and verification is relatively low. The thesis examine how verification is carried out and looks for an explanation to why verification is not more oftenly performed. To answer these questions two care studies, based on seven semi-structured interviews, is presented as the empirical material. Network theory has been used to analyse the empirical results, and aspects of commonly used theories such as contract management and "Markets and Hierarchies" by Williamson has also been taken into account.
Mellan digitala och fysiska världar : En utredning av immersionens och realismens retorik i kommersiella datorspel
This master thesis examines commercial video games and their relation to the concept of immersion and realism. Games as a communicative medium is quite a new area of interest within rhetorical research in Sweden. Most of the research conducted has, however, been focused on gaming and formation on opinion ? games that explicitly tries to persuade the player, unlike commercial games that focus on entertainment, that is. But that does not mean that commercial games cannot influence us.
