This masters thesis deals with smoke spread via ventilation systems. One aim of the thesis is to investigate and explain the differences in efforts to prevent smoke spread via ventilation systems in different countries. A second aim of this thesis is to investigate how frequently occurring smoke spread via ventilation systems in Swedish buildings are. A third aim is to investigate how uncertainties in input variables to smoke spread calculations will affect the result of calculation. To be able to do this the most important input variables are identified and analysed.

Real options analysis is a method for assigning value to flexibility in decisions, coming from uncertainty in future outcomes. This thesis ascertains to what degree this method is superior to traditional net present value analysis, with regards to ease of implementation in relation to the benefits from being able to measure the total value. Real options analysis is evaluated with a case study of the Swedish online gambling market, and conducted with the binomial framework of Copeland and Antikarov (2003). The authors find the sensible use of real options dependant on the specific situation to which it is applied, i.e. a certain degree of future uncertainty and managerial flexibility is necessary for justification of the increased workload.

Background: The intention of this study was to clarify the patients perspective of what it means to suffer fiom documented restenosis after one or more Percutaneous Coronary Intervention (PCI). Aim: The aim of this qualitative study was to ascertain the patients experience of restenosis. Method: Nine patients were interviewed. They had undergone at least one PC1 and two had also undergone Coronary Arterio Bypass Grafting (CABG). Data collection and analysis were done simultaneously according to Grounded Theory methodology and were continued until new interviews provided no additional information, i.e saturation was met.

In this master's thesis the problem of determining the uncertainty for an estimator of an unknown parameter is considered. The case we study is the estimation of gravity using a reversible pendulum. This involves the estimation of the point where two regression lines intersect. The estimated gravity is a function the coordinates of this point. One way to determine the uncertainty of this estimator is to use bootstrap methods.

In November 2007 the countries around the Baltic Sea signed the Baltic Sea Action Plan (BSAP). The action plan was an initiative from HELCOM due to the environmental status in the Baltic Sea. The action plan implemented a new approach with measures targeting the whole ecosystem. Eutrophication, hazardous substances, biodiversity and maritime activities constituted the main segments. The parties were to establish national implementation plans to fulfil the BSAP goals, which shall lead to good environmental status in the Baltic Sea by 2021.  The aim of this thesis is to investigate the points in common regarding conceptions of eutrophication in the Baltic Sea between the management, the science, the media and the public.

A real option model is developed to examine the crucial factors affecting the agricultural firms? decision to quit the production and rent out the land to a company building a PV power plant. The public policies in support of investments in renewable energies have created the conditions for a market regarding investments in PV installations in agricultural areas.The decision to switch offers to the agricultural firm and to society several economical, social and environmental benefits, representing sustainability. However, PV installations in agricultural areas require the allocation of a certain land area. By assigning a part of land to PV installations, thereby the area of land allocated to agricultural production decreases.

The market risk premium is one of the most important parameters in finance. Its value and the ways to calculate a risk premium for the market is a widely debated subject. This thesis examines numerous ways of calculating a risk premium for the Swedish market with regard to how good an estimation they make of a real risk premium. Estimations based on historical periods ranging from 20 to 85 years is calculated as well as a premium based on forward-looking estimates. The real risk premium is solved out for a selection of companies and an index with the help of CAPM.

Background and research problem: The former highly inflationary property market is currently undergoing a stagnation process. Investors have been used to annual growth figures in double digits,but now this is no longer considered to be a realistic outlook for future years. According to a report from PriceWaterhouseCoopers and Urban Land Institute, published by Avanza Wealth Management,the three most attractive markets for property investment in Europe are London, Paris and Stockholm. Because of this the authors have focused their investigation on two companies in the London andStockholm. The authors will additionally use an international bank, an estate agent and a consultancy firm for further information, with regards to the property market and risks associated with these typesof investment in particular.

Included in theses aims is to examine potential problems with the current risk management and to suggest changes. It is of utter importance to define the concept of risk, to study how risk can be measured and in which ways risk can be analyzed. In doing so, a literary study has be done and fourteen respondents has been interviewed.Risk is to be seen more as a concept than a quantity.

Syftet med denna uppsats är att undersöka uppfattningar om risk inom mödrahälsovården. Den behandlar hur barnmorskor och deras patienter uppfattar risk i samband med och runt en graviditet och hur de hanterar denna. En av metoderna för att hantera risk är fosterdiagnostik, vilket syftar till att finna riskgraviditeter. Fokus har främst varit på barnmorskor med frågeställningar kring hur de informerar om risk och fosterdiagnostik, hur de ger råd och hur de uppfattar den inverkan detta har på deras patienter och hur dessa reagerar..

In this essay, Risk and crisis management Conservation policy and normalization production, I discuss how societies, communities and individuals are responsible for the handling of catastrophes and crises. Risk and vulnerability analyzes are parts of modern risk and crisis management. The purpose of these analyzes is to prepare people and organizations for any crises. For managing this it is necessary to comprehend, be able to change mindset in creating concrete tasks and inform others.The purpose of this essay is to analyze modern risk and crisis management by studying empirical material, such as interviews, observations and literature. My aim is to combine these materials and study how they cooperate.One of the findings in this essay is that risk and vulnerability analyzes are of great complexity. These analyzes require a discussion in order to identify the development of the society's crisis management system, as well as the continued support of the individuals that have a responsibility for preventing and preparing their organizations..

Information about the risks involved shall be distributed to the people living in the area nearby to potentially dangerous installation. Swedish law stipulates strict requirements on what information should be supplied, but the law itself does not give any guidance on presentation. The main purpose of the study is to give recommendations on how to improve the information brochures. Within the study, eight people working with risk information have been interviewed and seven different risk information brochures have been studied. Also, a theoretical analysis and a practical experiment were performed using brochures from two municipalities.

All companies face risk in their daily business. Internationalised companies tend to experience higher risk due to for example unfamiliar business environment than companies that act only on the national market. Estonia became independent as late as in 1991 and is therefore a new interesting market for many companies in neighbouring countries like Sweden. Risks that are most apparent for an internationalised company are political risk, currency risk, capital and interest rate risk, business risk and credit risk. Our intention of this study was to find out how Swedish companies acting on the Estonian market faced the different risks when entering the Estonian market and how they value the risks today.

Introduction: The world is changing rapidly and the uncertainty that characterizes today´s society makes companies preparations for the future crucial. Purpose: To examine how CEO:s in small companies look at the future and what kind of preparations they make in order to meet it. Hereby, our ambition is to find out whether there is a difference between companies working in industries characterized by different degrees of stability. Mode of procedure: The purpose of this thesis has been fulfilled by interviews with four CEO:s from industries characterized by different degrees of stability. Result: The companies working in relatively unstable environments tended to be relatively more flexible and have an emergent strategy formation process, whereas companies working in relatively stable environments displayed relatively less flexibility and tended to have a planning strategy formation process..

Something that all people have come across and more or less experienced is climate change. Climate change in itself is a very complex problem since there are no borders between countries that can stop the problem. The link between science and the public is largely in the hands of the media, since the media play an important role in defining environmental issues and to inform the public about research findings. In recent years, reports from the media showed a slightly skeptical and uncertain picture of this problem. This is despite the largely prevailing consensus among climate scientists that there is an anthropogenic climate change.
