The so called ?ByggaF-method? is a relatively new Swedish method to stop moisture from being built into a building. The method should prevent damages on buildings as a result of mould growth and moisture. The purpose of the method is to include moisture control in the entire constructionprocess, from the projecting phase and all the way to the management phase. Up until now, there is no proof if the method is profitable or not and no studies have been made on the topic.

I dagens globaliserade samhälle är det enkelt att placera sitt kapital på olika marknader. Dock kan det innebära både risker och möjligheter för investeraren. Vilket betyder att det satsade kapitalet antingen kan bli en lönsam investering eller gå förlorat. Bör hänsyn tas till landsrisker på aktiemarknaden för att kunna bedöma investeringens lönsamhet?Syftet med studien är att ta reda på vilken betydelse landsrisker har för avkastningen i industri- respektive tillväxtländer.

Företag idag söker ständigt nya och förbättrade konkurrensfördelar, som är en konsekvens av den snabba och ökande globaliseringstrenden. Ett viktigt grundincitament för att skapa dessa fördelar samt bemöta omvärldens föränderlighet och krav har bidragit till att allt större fokus riktats mot behovet av en bred kompetens, det vill säga ett utvecklat humankapital, inom företag. Humankapitalet är en av de mest betydelsefulla grundpelarna i ett företag då företaget är beroende av de anställdas kompetens och innovationsförmåga. Det är således viktigt att ett företag styr humankapitalet på ett sådant sätt att det når en stärkande eller förädlande effekt. Ett sätt för att strategiskt styra förädlingsprocessen av humankapitalet är att nyttja Simons Levers of Control, vilken även går under benämningen Simons styrmodell.

The real estate industry is a sector where the companies generally have a capital structure which is high leveraged. The financing? with the related terms ? is therefore specifically of high importance for the companies in the sector. Traditionally, the way of obtain financing is by borrowing from the bank. Lately, due to new bank regulations, the banks have become more restrictive in their lending which have lead to a growth of other financing alternatives.

Active headsets have been on the market for years and now it is time for something else to enter the stage. The technology of active noise reduction can for exmple also be used in ventilation systems for reducing ventilation noise. An active control system principally consists of four important components, namely the downstream error microphone, the upstream detection or reference microphone, the digital signal processor (DSP) and a loudspeaker. The upstream reference microphone listen to the primary ventilation noise and sends it to the DSP which makes a phase shift to the signal and sends it to the loudspeaker. The loudspeaker sends out the opposite waveform of the incoming one and reduce the primary ventilation noise.

Background: Each year approximately 30 000 people suffer from stroke in Sweden, often with substantial mental and physical consequences.

For those who provide care for people who has suffered a stroke help and support was required. The caring science perspective was based upon caring and suffering. Aim: The purpose of this study was to describe family caregivers? experiences of caring for persons who had suffered a stroke.

Andelen ungdomar som inte uppfattar några större risker med cannabisbruk har ökat de senaste åren. Ungdomarnas uppfattning av riskerna med cannabisbruk påverkar huruvida de kommer att välja att avstå från eller bruka drogen. Syftet med denna uppsats har varit att se vilka risk- och skyddsfaktorer som påverkar ungdomars riskperception avseende cannabisbruk. Frågeställningarna har varit hur föräldrarna, skolan och vännerna påverkar riskperceptionen. Uppsatsen utgår från en subjektiv syn på riskperception som innebär att inte en faktor ensamt kan förklara om ungdomarna har en låg eller hög riskperception.

This master thesis encompasses an inventory of the older industrial community of Gimo. Investigations of the contamination situation for each industrial area were done. A risk classification according to the Swedish Environmental Protection Agency?s ?Method of Surveying Contaminated Sites?, phase one, followed. The risk classification was done on areas of Iron Work, a rockwool industry and a landfill. Gimo have had iron manufacturing from 1615 until 1945. Gimo have had two blast-furnaces and two smithies periodically.

This Thesis aims to explore how to integrate an IT-system for facilitating anorganizations work with Continous Impprovements.This is done here by examining and analyzing the process within a handful ofcompanies who seem to have been successful with their own implementations. Thestudy is focused on the implementation of one particular system, "System C2".Simliarities and differences between the companies, and the established rule of thumbfor these kind of activities are focused upon. This to emphasis how another actormight emulate some of the apparent success.Part of the core question is found in the title, since Continous Improvement is oftenseen as a relativly low-risk activity, is it then also possible to take a low-risk slow pathto the implementation of such a system in the entire organization?.

Friend lists allow Facebook users to group their friends and may be used to share certain information only with those in a specific list. This function has been around for several years, but has never gained any particular popularity among users, most of whom probably did not know it even existed a couple of years ago. In the fall of 2011, however, the function was updated and made more visible on the site.There are several possible uses of friend lists, such as privacy control, filtering of the news feed, self-presentation and targeted information sharing. This paper aims to investigate the extent to which friend lists are used by students today, as well as why students actually use their lists, i.e. for what purposes.Judging from the results of this study in comparison with earlier research, there seems to have been a somewhat recent increase in the awareness of the fact that friend lists actually do exist, but still most users tend not to utilize them.
