Risk eller Resurs: En studie av hur riskbegreppet konstrueras i den svenska kÀrnkraftsdebatten
Looking at the debate on nuclear power in Sweden, the issue of risk is central to understanding the difficulties in resolving differences between proponents and opponents. I sought to answer the research question: "how is the concept of risk constructed in the nuclear power debate in Sweden?" Four main aspects of risk construction were defined and investigated to identify differences between sides in the debate. Through a qualitative study of the debate and its actors I found clear differences in respect to all four aspects of risk construction. First, the perception of nuclear power as a "normal risk" is common among nuclear opponents in contrast to a largely probabilistic view among proponents.
Icke förnyelsebara risker : Svenska gruvbolags riskhantering av en eventuell framtida metallbrist
A major issue that has been a subject for quite some time is whether there will be a scarcity of metals in the bedrock in the future and whether or not we might end up with a problem similar to that of the big oil crisis in the mid-seventies. Following the oil crisis many oil companies started up with risk management to control future risks. This work presents how Swedish mining companies work with risk management to handle risks that might come up in the future due to metal scarceness. How Swedish mining companies look at the possible metal scarceness and if they use risk management in their decision-making process is studied. By doing interviews with Swedish owned mining companies it was found that the mining companies did not see the future metal scarcity as a risk, even though 2/3 of the companies acknowledged the scarceness to be a reality.

Förorenad mark Förekomst och spridning av koppar och zink i GrĂ€sdalenanlĂ€ggningens nĂ€romrĂ„de, Gusum, Ăstergötland.
Förorenade omrĂ„den kan utgöra en stor risk för den omgivande miljön. Föroreningar som tungmetaller kan pĂ„verka det mikrobiologiska livet samt genom urlakning föras ut i grundvatten och vidare förorena omgivande miljö och dricksvatten. Tungmetaller tas Ă€ven upp i organismer och sprids vidare i nĂ€ringskedjor och kan ocksĂ„ nĂ„ mĂ€nniskan genom föda som vĂ€xer eller odlas pĂ„ förorenad mark. Föroreningar i mark hĂ€rstammar oftast frĂ„n gammal industriell produktion, sĂ„ Ă€ven i och omkring samhĂ€llet Gusum i Ăstergötland. HĂ€r har verksamhet med smĂ€ltverk bedrivits sedan 60-talet och Ă€nda fram till början av 80-talet var rökgaserna frĂ„n verket orenade frĂ„n metaller och har kraftigt förorenat och skadat nĂ€romrĂ„det kring bruket.
Den militÀra nyttan av kurskorrigerande tÀndrör
Sveriges ökade engagemang i internationella konflikter har förÀndrat under vilkaformer och i vilka miljöer som dagens militÀra operationer genomförs. FramföralltinnebÀr det att alla insatsförband inom Försvarsmakten ska kunna verka inom allakonfliktnivÄer och i de flesta miljöer, Àven i urban terrÀng. Som en följd av dettauppkommer nya behov och krav pÄ den indirekta bekÀmpningsförmÄgan i form avprecisionsbekÀmpning.Syftet med föreliggande arbete Àr att kartlÀgga om, och till vilken grad, ettkurskorrigerande tÀndrör bidrar till att öka den taktiska effektiviteten förstÄdd somverkanseffektivitet, kostnadseffektivitet, logistisk effektivitet samt minskad oönskadsidoverkan. KartlÀggningen sker genom en komparativ litteraturstudie medkompletterande expertintervjuer.Med hjÀlp av kurskorrigerande tÀndrör som medger nÀra precisionsbekÀmpning kanen rad vinster erhÄllas.

Hur skapas en effektiv riskhantering? : En studie av telekomoperatörer
Background: As companies are operating in more globally and complex environments, the need for risk control is accelerating. In an ever-changing environment, companies cannot merely focus on traditional risks, which include financial and insurable risks. To maintain competitiveness, companies need to extend their risk management to include all risks, traditional as well as operational and strategic risks. Purpose: The purpose is to describe and position risk management for Telecom operators, in comparison with the risk management literature, with regards to structure, processes, learning process, visions and benefits. In addition, our aim is to link risk management perspectives with the different strategies for knowledge management.
Motiverad för riskmedvetenhet? En studie om stadsarkitekterna i Dalarnas lÀns medvetenhet om, motivation för och arbete med risker vid fysisk planering.
The purpose of this study is to examine how risk is perceived by the urban architect's in the region Dalarna, as well as how this is reflected in their everyday work with risk and decision- making according to urban planning. The ambition is also to show how their risk awareness could be improved. The study is written in cooperation with LĂ€nsstyrelsen Dalarna as a part of their regional long-term goal to improve the region's proactive risk' and crisis management. The study is based upon 12 semi-structured interviews with local urban architects conducted during the summer and autumn 2007. The result shows that some architects are motivated for working with risk and think that risk awareness should be integrated in their everyday work, while others are not motivated and think that risk is more of a passing trend.
Diffusionen av SOA
Uppsatsen Àmnar ge en indikation om diffusionen av den tjÀnsteorienterade arkitekturen SOA, idag och dess framtida diffusion. Genom att operationalisera begreppet SOA med hjÀlp av litteratur har vi kunnat sammanstÀlla en enkÀt i syfte att utföra en enkÀtundersökning. Genom det empiriska material vi samlat in har vi kunnat applicera detta i en modell för teknologisk diffusion, i syfte att ge en indikation i form av en graf för diffusionen av SOA. Resultatet visade pÄ en överraskande hög spridning av SOA dÄ sannolikheten för spridningen blev vÀldigt hög. Vi misstÀnker att vissa system- och programutvecklingsföretag tror sig ha spridit SOA utan att de gjort det.
Direktinvesteringar och risk : Finns ett samband?
Beslut om och var man ska genomföra en direktinvestering grundar sig pÄ en rad faktorer. En av dessa Àr den risk som Àr förknippad med investeringen. Den hÀr uppsatsen tar upp risk i form av volatilitet dels pÄ aktiemarknader men ocksÄ för vÀxelkurser. Med utgÄngspunkt frÄn tvÄ teorier dÀr den ena sÀger att hög risk Àr förenat med en lÀgre nivÄ av direktinvesteringar samt en motsatt som istÀllet menar att hög risk leder till en högre direktinvesteringsnivÄ undersöker jag situationen för USA och Sverige. Genom att undersöka just dessa lÀnders marknader fÄr man en bild av ekonomins storleks betydelse för huruvida risken pÄverkar direktinvesteringar eller inte.
Projektrisk : en studie av svenska bygg- och anlÀggningsföretag
Background: Today businesses are largely structured in projects and temporary organizations. In many companies, the ability to pursue projects is decisive for the business efficiency and competitiveness. The risk literature do not discuss identification and handling ofproject risk in building- and construction companies to a large extent, which has led us to investigate how project risk can be treated and handled in Swedish building- and construction companies. Purpose: The purpose of this thesis is to cover and describe business risk in Swedish building- and construction projects with focus on different risks and risk tools, and also to modify a model for evaluating the business risk maturity. Realization: This thesis has both traces of a case study and a cross-section study and examines eight different companies that are active in the building- and construction business.

Nöjda kunder med risken i fokus : En studie i hur finansiell risk bör förmedlas
During the last decades major changes has occurred at the financial markets, meaning an increasing supply and a greater variation of financial instruments. The saving habits of the Swedish people have gone from traditional bank deposits to investments in equities, funds and bonds. All this together with the great rise in the stock market at the late 90?s has brought words like risk and return up-to-date, and is the background to the development of a new law concerning financial advising which come into force the 1th of July 2004. The contents of the thesis can be described as three bricks, representing the survey questions.
Riskbedömning och naturligt producerade dioxiner
The highly toxic man-made substance referred to as dioxin (polychlorinated dibenzo-para-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs)) causes severe health damages both to humans and other organisms, with lethality as its worst. Because of the toxicity several risk assessments has been performed on dioxins trying to determine at what concentration there are no risk of exposure. Resent years of research has discovered that these substances are not only anthropogenically but also producedin natural processes, like volcanoes and forest fires. To investigate if there is a need to take these naturally formed dioxins into account in the risk assessment processes, interviews with persons at relevant institutions in Sweden has been made. Analyses of existing risk assessment methods and political documents were also made to complete the picture.
Plötslig spÀdbarnsdöd, ett kÀnsligt Àmne : En litteraturöversikt om risker, förebyggande ÄtgÀrder och sjuksköterskans roll vid SIDS
Background:The sudden infant death syndrome (SIDS) has always existed. In the early 1990's, researchers discovered that prone position was associated with a significantly higher risk for SIDS. This resulted in a lowered incidence of SIDS in the world. The campaign showed the value of risk knowledge and risk reducing methods, that's why new information campaigns about other risks regarding SIDS must occur.Aim:The aim was to describe the risk factors and preventive actions for SIDS, and the nurse's role regarding the preventive work. Method: A literature review based on 16 articles based on qualitative and quantitative studies.
