Osäkerheter vid riskanalyser i samband med transport av farligt gods

Risk analysis in connection with transportation of dangerous goods is associated with great uncertainty. In addition there are a number of specific problems that the risk analyst faces when risks associated with transportation of dangerous goods are to be analysed. In this report those problems and uncertainties are described.One of the most important conclusions in this report is that uncertainty analysis within risk analysis in connection to transportation of dangerous goods has to be made more effective..

Risk och osäkerhet vid inträde på den svenska apoteksmarknaden: En studie om nya aktörer på en marknad under omreglering

The Swedish pharmacy market will be re-regulated in July 2009 which will present private actors with an opportunity to enter the market. Several risks and uncertainties are associated with such an entry. The purpose of this thesis is to increase the understanding of identification and management of risks and uncertainties associated with entering the Swedish pharmacy market. We also intend to investigate similarities and differences in risk identification and risk management as well as create an understanding of the underlying reasons for these similarities and differences. Three companies interested in entering the market have been interviewed and the interviews were conducted with an open approach to avoid influencing the companies? answers.

Ovisshetens uttryck : En empirisk studie baserad på berättelser om ovisshet.

Background: Many people within the health care system experience uncertainty. Uncertainty can be described as a feeling, a condition or as a phenomenon. Uncertainty is often associated with stress and an emotional burden among patients. It?s important for the nurse to have knowledge about the expressions of uncertainty to get a higher appreciation for the patients? situation.

Uppamma mod och utjämna makt : Ett aktionsforskningsprojekt där arbetsredskap utformades tillsammans med sjuksköterskestudenter för att kunna lindra för personer att leva med ovisshet.

Uncertainty is a well-known phenomenon that is recurring in biographies, imaginative literature and science, but is less studied in nursing science. The aim of this participatory action research project was to, in collaboration with nursing students; explore nursing activities for relieving patients? uncertainty. A qualitative approach was chosen with focus groups and the text was content analyzed. The students studied their third semester on a nursing program.

Ovisshet, ett begrepp att räkna med. En begreppsanlys

Abstract This Concept Analysis according to Walker & Avant (1995) studies the concept of uncertainty in the nursing context. It consists of four parts where uncertainty in general have been encircled in a semantic analysis (part one) and a qualitative content analysis consisting of an questionnaire, distributed to the staff members at one nursing and medicine institution, with an open question about the meaning of uncertainty (part two). The third part is a literature study of the nursing context to find out how uncertainty is described (part three). Part four is the actual concept analysis based on the three first parts. Uncertainty in the nursing context is an individual conscious experience witch is changeable and impressionable. It is chained together with its antecendents and consequences.

Demokrati och vetenskap - ett problemfyllt förhållande

What role should science play in democracy? Political scientists often assume that it is possible to demarcate between ?instrumental? and ?moral? knowledge, and argue that citizens and/or politicians should use their moral knowledge to agree upon political goals and then apply the instrumental knowledge of scientists to achieve them. This straightforward view is challenged by writers in science studies, who identify three major problems in the use of science in democracy: uncertainty, risk and hidden values. They suggest that these problems could be solved through citizen participation.In this essay I perform an analysis of the internal logic of their suggestion. Is it likely that citizen participation enhances the democratic decision making process so as to reduce the problems? The internal analysis shows that it is rational to advocate citizen participation by reasons of legitimacy.

Kan risken för finansiell kris förutsäga första dagens avkastning vid börsintroduktioner?

This thesis studies the relationship between risk and the first day returns of Initial Public Offerings (IPO) by assessing the risk of each issuing company with a risk model that combine financial key ratios of importance. The study is based on 92 IPO?s that were made on the Stockholm OMX stock exchange during the period of 1997-2009. The point of departure was to investigate if the uncertainty created by the asymmetric information between investors and the issuing firm could be captured by predicting the possibility of failure in the future. This has been studied by applying Skogsvik?s probability of failure model on the 92 issuing firms.

Kvantifiering av osäkerheter i lyftkraftsmodellen

With today´s power uprates in BWR reactors the bundle lift force has become aproblem. The lift force is calculated using a best estimate approach and the resultfrom the calculation should pass the existing lift force margin. Lift force margin isdefined so that the lift force may not exceed 80 % of the fuel weight. The margin issupposed to cover all the uncertainties that exist in the lift force calculations.However, no uncertainty analysis has been conducted to quantify the uncertainties.In this report the uncertainties in the lift force model have been quantified. Each inputparameter to the lift force model which has been assumed to have an uncertainty isassigned a probability distribution.

Intern kontroll och riskhantering

The accounting scandals that have attracted attention in recent years have led to internal control becoming a more central part of business activity. Doubts about what firms actually do have increased, all caused by the attention of accounting scandals. To counter this, frameworks and laws evolved and gained a significant role in the organization and its surroundings. The aim of the present study is to find out how four companies in the Kristianstad region are working to ensure its internal control and how they work to minimize risk and reduce uncertainty. We have used a qualitative method and interviewed a person in a senior position in each company.

Påverkar goodwill kapitalkostnaden?

Does goodwill affect the cost of capital? Goodwill is an asset which is characterized by much uncertainty regarding both what it is and how much it is really worth. Based on economic theory about information risk and principal-agent problems as well as theory regarding the cost of capital we test for the hypothesis that debt and equity investors perceive goodwill as something risky and hence demand compensation for taking on this extra risk. The proxies used for the cost of capital are cost of debt, beta and the EP-ratio. On a general level we find that increasing the level of goodwill seems to result in higher cost of capital as represented by the three proxies.

Systematiskt arbete för att hantera osäkerheter vid mätning : vid Q-Med AB i Uppsala

This report is about helping Q-Med AB in Uppsala to start its implementation of uncertainty of measurements analyses in their manufacturing department. Prior to this, the company relied solely on personal experience or did not take this uncertainty into consideration at all during different kind of measurements, which means that some of the processes that the company previously believed were within specified acceptance limits, will actually fail when considering these sources of uncertainties.Q-Med AB needed some sort of instruction to help the company, in a systematic way, to investigate different types of disorders that are affecting all kinds of measurements. This instruction includes a short summary about measurements and uncertainty of measurements in general and a detailed procedure about how these uncertainties are going to be handled in their daily work.The goal was to be able to use this instruction to systematically locate, eliminate (when possible) and analyze all kinds of disorders when measuring. Q-Med is using a lot of different types of instruments when measuring different types of quantities, including temperature, mass, pressure and density. This instruction will hereafter be used for every instrument, regardless of quantity and type of instrument.The instruction is tested through 4 different kinds of measurements, for mass, temperature and humidity.

Foreign direct investments under political uncertainty : a case study of crop production in Ukraine

Intense competition among companies and luck or unavailability of certain resources in country of company?s origin force last to cross the borders, and start to hunt for new markets and cheaper inputs. However, by investing abroad the company is not only facing and dealing with cultural differences and new regulatory framework, but also becomes dependent on decisions and actions of different and to large extend unknown government. Moreover, the majority of the investments? flows are directed to developing countries, where power and capabilities of state authorities are considered to be more extensive than in countries of developed economies.

Investering i tidig läkemedelsutveckling. En studie om hur man tar beslut under osäkerhet.

This case study aims to explore how decision making is performed under circumstances characterised by high uncertainty. We have identified and interviewed two types of organisations dealing with investments in pharmaceutical drug development, a business characterised by high uncertainty. We have found that the two types of organisations we have interviewed display different decision making behaviour evaluating the same type of investment. Further we have explained these differences in decision making behaviour by using relevant decision making theories. This study has showed that different forms of decision making are appropriate depending on the conditions facing the decision maker..

Osäkerhet i energisimuleringar av flerbostadshus : Analys av fem nybyggnationer

Since energy simulations are used to verify that projected residential buildings will reach the current energy requirements it is important that the results are reliable.This report investigates the extent of uncertainty in energy simulations, estimates the causes of the uncertainty and its economic and environmental consequences.The method used in this report is based on three validation methods; empirical validation, analytical validation and comparative validation. The analysis was carried out for five multi-family dwellings in Uppsala with installed meters for energy measurements. One of these objects, Klockarlunden, was studied in more detail than the others.The results show that the deviations are between 10 and 29% for the studied objects, which means that the uncertainty is estimated to be at least 29%. All simulations underestimate the buildings need of energy. The simulation for Klockarlunden can predict the energy consumption to be within the range of 46-98 kWh/m2year with 90% confidence level based on the current uncertainty.
