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.
Bestämning av osäkerheten hos skattningar av tyngdaccelerationen
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.
Photovoltaic installations and land allocation under uncertainty : a real option approach
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.

Media, en ignorerad länk i den strategiska berättelsen : En kvantitativ studie över medias projektion av det svenska Afghanistannarrativet
The Afghan war post 9/11 has become the source of multiple case studies. Recent studies suggest that variations in domestic support for deployment of troops in Afghanistan can be explained by means of the strategic narratives provided by the policymakers of the contributing state; a strong consistent narrative increases public support. Scholars recognize a Swedish catch-all narrative, which suggests weakens the narrative, thus raising the uncertainty among the public. This thesis investigates the projection of Swedish strategic narrative through elite Swedish newspapers. The content analysis reveals an inconsistency between the policymaker?s formation of the strategic narrative and the narrative projected by individual newspapers.
Intuition : En studie av beslutsfattande i mindre svenska företag
Background: Previous studies have shown that intuition occurs in decision making in small enterprises. However, these studies have not illuminated which decision attributes leads to intuitive decision making.Purpose:The purpose with this study is to contribute with an increased understanding of which decision attributes leads managers in small enterprises to use intuition in decision making and why these decisions attributes have an impact on the role of intuition. The follow-ing research question will be answered in our study: Which decision attributes leads to intui-tive decision making in small enterprises, and why?Method: To answer the research question we have conducted semi structural interviews with managers in small enterprises to achieve a deeper understanding of the role of intuition. We have also used a method called Visual Card Sorting as a complement to the semi structural interviews.Result/conclusion: The result of our study indicates that the relevance and the uncertainty of a decision have the greatest significance in the use of intuition in decision making in small enterprises.

Man promenerar i dimma - En studie av flyktingars berättelser om asylprocessen
This essay is based on seven lifestoryinterviews with people who are undergoing orhave undergone a long asylum process. Four women and three men have contributedwith their stories about their experiences of waiting for a determination of theirapplication for residence permit. The main aim of the essay is to give betterunderstanding of how to be a refugee and a long asylum process affects people's abilityto narrate and thus examine their opportunities to be active in the construction of theirown identity.The questions that are debated and discussed are:? What can it mean for an individual's identity to escape her country and for a longtime wait for decision of asylum?? What stories can be told?? What reality are highlighted as central in the stories?? How do they handle their situation and give meaning to their lives?The analysis is based on two main theoretical perspectives: narrative theory and identitytheory. The approach is that people create meaning of events through storytelling andthat they through this process of narrating construct (and reconstruct) their identities -the self image as one have and wants to present to others.In the analysis three different types of stories are distinguished, stories that arerepresented in the empirical material: the story that can not be told, the story that mustbe told and the story that are gladly told.
Nytta, skada och kostnader vid screening för bröstcancer med mammografi
The efficacy of screening for breast cancer with mammography has been a subject of controversy during the last decades. However, the general opinion is now that screening reduces mortality in breast cancer (Zackrisson, 2006). It is nevertheless important to weigh the efficacy against the harm and costs associated with screening. Cost-utility and cost-effectiveness analysis of screening have generally failed to incorporate side effects such as anxiety and discomfort related to screening tests and the following diagnostic tests (Gyrd-Hansen, 2000). This study seeks to include such side effects in a cost-utility analysis.

I väntan på framtiden : en studie av mindre företags förberedelseinför framtiden
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..
Medarbetares behov av kommunikation : Ett medarbetarperspektiv på kommunikation vid en organisationsförändring
Changes are occurring in most organizations today and due to the fact that changes often are harder to implement than they seem, it often takes much longer time to implement them than the management have planned. During an organizational change theorist claim that communication between managers and employees is one of the most important things to consider. Therefore, in this essay, our aim is to closer investigate which needs of information and communication co-workers have during a planned organizational change. To collect data, we interviewed five co-workers and one manager who works in an organization which has gone through a major change. Our theoretical framework comprises former research of organizational communication, employee?s needs of communication, change communication and theories of uncertainty during organizational change.
De kommunala miljöarbetet : En uppsats om miljömedvetenhet och medborgarskap
The work with Agenda 21 resulted in a larger focus on local participation and deliberation. The Swedish implementation of Agenda 21 is a result of these local governments´ political agendas and policies.The purpose with this paper is to examine the relationship between the citizen and the local government. It focuses on three theories of citizenship and how the view of "the environmental aware citizen?; in the local government?s municipalities policies differ and from which theory of citizenship do they come from.The analysis is of a valuing and comparing nature. The municipalities´ web pages have been the main source to generate an understanding of their view on the normative environmental work.
Det främsta arbetsredskapet ? Sjuksköterskans erfarenheter av det vårdande samtalet med patienter inom psykiatrisk öppenvård
Introduction: The conversation is one of the main components of the nursing process in psychiatric care. The preunderstanding on this research field is described based on theoretical concepts that together form the basis for understanding the study; nurse's role in psychiatric care, communication and caring relationship, as well as theories of the caring conversation and person-centered care. Research on the caring conversation as a theory and how it is experienced by patients existed, however, no research from the nurse's perspective was found.Aim: The aim of the study was to describe nurses' experiences of the caring conversation with patients in psychiatric open care units.Method: Qualitative research interviews were conducted with six nurses working in outpatient psychiatric care in the west region in Sweden. The interviews were recorded, transcribed and then analyzed according to the qualitative content analysis as described by Graneheim and Lundman (2004).Results: Four categories with related subcategories were distinguished throughout the analysis: The caring conversation, The importance of the care plan, Limitations and Caring based on the patients narrative.Discussion: An uncertainty about what caring conversation is and what it should contain creates uncertainty in the nurse's work. This results in a need for training for the individual nurse and the further research to obtain evidence for the importance of conversation in caring work.
Miljo?klassning inom infrastruktur och anla?ggningsprojekt : - en fo?rdjupning inom CEEQUAL
This thesis has evaluated environmental classifications of projects and the lessons learned to explore what the possible ramifications of implementing this in the construction and infrastructure are. Companies today are looking to develop methods to demonstrate their environmental commitments, but there is an uncertainty regarding the contribution of environmental classifications in this aspect.The literature review presents the theory of environmental classification, which provides a general knowledge of its function. The empirical data is based on an analysis of existing classification methods and qualitative interviews. The analysis shows specific environmental classification system for the area of construction and infrastructure. CEEQUAL is currently the only environmental classification applicable to Swedish projects and therefore serves as the basis for the continued analysis.
