Giganters Kamp - en undersökning av konfliktlösning och förhandling i handelskonflikter
This paper is an attempt to distinguish the specifics of the conflict resolution process and the negotiations during trade conflicts. First of all, this kind of conflict almost always contains some kind of protectionism which doesn?t make sense economically. Imposing trade-barriers decrease the overall welfare of your own nation and the only winner is the protected sector. These policies can be introduced since the political pressure from threatened industries is usually much stronger than the pressure from the consumers who will bear the burden of protectionism.
Vad förklarar variationer i frivillig information?
There is an increased pressure for firms to provide the financial market with additional information. Such disclosure is attached with different kinds of costs. In spite of these costs, and in spite of increased mandatory disclosures, firms choose to voluntary disclosure financial information to analysts and others. This indicates that firms also benefit from providing additional information. The subjects of this study is 431 annual reports from firms listed at the Stockholm Stock Exchange for 2002 and 2005 and the objective is to survey factors that can explain variations in firms? voluntary disclosure.
Energieffektiv ventilation som lösning på radonproblematik i bostadsområde
Bostadsbolaget Mitthem AB äger 11 tvåvåningshus med lägenheter på Uppsalavägen i Sundsvall. Spårfilmsmätningar har visat på radonhalter över gränsvärden i flertalet lägenheter, vilket också konstaterats bero på markradon. I dagsläget är lägenheterna utrustade med F-ventilation utan värmeåtervinning. I detta arbete utreddes möjligheten att lösa radonproblematiken genom införande av energieffektiv ventilation med värmeåtervinning. En sådan åtgärd kan påverka radonhalten genom förändring av dels luftomsättningen och dels undertrycket inomhus.

Att mäta ankeltryck i primärvården : Distriktssköterskors och distriktsläkares uppfattningar om en undersökningsmetod och dess användning
Background: Peripheral arterial disease (PAD), as a consequence of atherosclerosis in the arteria of the limbs, affects one of ten Swedes older than 65. PAD can develop slowly and silently, and involves an increased risk for cardiac infarction and stroke. Measurement of the patient´s ankle blood pressure and calculation of the ankle-brachial index is an evidence-based method to discover PAD. Objective: To investigate how district nurses and general practitioners perceive this method of examination and experience possible obstacles to why it is not more commonly applied at primary health care centres. Method: Data collected by semi-structured interviews have been processed by qualitative content analysis with a manifest onset.
NNN... Nostalgi: Om effekterna av nostalgi vid konsumtion
The presence of nostalgic emotions during consumption is often seen as something purely positive to a product. To evoke these emotions has become a very common tool in marketing and advertising. Paradoxically very few studies have focused on the effects of nostalgia. The purpose of the thesis has been to understand how the presence of nostalgic emotions during consumption effect consumers. The research model used is a quantitative study with testing of hypotheses generated from theory.
Operationssjuksköterskan-en sterilklädd dörrvakt? En observationsstudie
Current research shows that the number of door openings during surgery is unjustifiably high. It is the operating room nurses task to ensure a hygienic and aseptic environment throughout the surgery with the goal of minimizing the risk of healthcare associated infection. The study aims to investigate whether the operating room nurse is attentive to the number of door openings during surgery and if the operating room nurse is attentive to the reasons behind the door openings. A pilot study with nine observations was carried out on two smaller hospitals in the region of Västra Götaland. The results showed a significant underestimation of the rated door openings compared with the actual ones.
Upphängningssystem
Examensarbetet som utförts på Institutionen för Maskinteknik vid Blekinge Tekniska Högskola i samarbete med Kockums AB har benämningen ? Upphängningssystem?. Dagens upphängning av rör, ventilationsrör och kabelbanor består av ett antal olika singelupphängningar utan större samordning. Detta har gjort att Kockums AB önskat få fram ett samordnat upphängningssystem som klarar av alla dessa upphängningstyper. Utifrån denna problemställning har vi arbetat oss fram till ett upphängningssystem bestående av ett multisystem och ett flertal singelupphängningar för rör, kabelbanor och ventilation.
LCC på ventilationssystemet på en skola : en undersökning huruvida VAV eller CAV är mest ekonomiskt i längden
Vid projektering idag ställs konstruktören ofta inför valet att projektera för antingen ventilation med konstanta flöden, eller med variabla flöden. Vidare kan även flödena varieras manuellt eller automatiskt. Det konstruktören måste ta hänsyn till är investeringskostnaden, men även potentiella energi- samt kostnadsbesparingar över tid. Många gånger är det svårt att veta hur energianvändningen påverkas av de olika systemvalen varför det är svårt att välja det mest optimala systemet.Detta arbete undersöker livscykelkostnaden, LCC, med nuvärdeskostnaden på en skola i Uppsala med tre olika system, antingen konstant ventilationsflöde, CAV med timer, manuellt styrd variabel ventilation, VAV, eller automatisk VAV med styrning på temperatur och CO2. Huvudanledningen till det är att skolor består av en mängd olika klassrum och lokaler som inte alltid används under skoltiden, risken finns alltså att skolan överventileras med ett traditionellt CAV.
Livscykelanalys för koldioxidutsläpp från flerbostadshus
Today, about 15 to 20 percent of Sweden?s total emission of carbon dioxide can be traced to the household sector. By examining apartment blocks in a life cycle perspective, the origin of the carbon dioxide emission has been charted and analyzed. This information has been used to create a computational model that calculates the total emission of carbon dioxide from a specific apartment block. The results from the analyzed apartment blocks indicate that both the use of energy and the emission of carbon dioxide have been reduced since the 1960s. Through the examination of building materials, it is possible to lower the emission of carbon dioxide that origins from the construction phase of an apartment block.
