Projektrisk : en studie av svenska bygg- och anläggningsföretag

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.

Tankens makt - Påverkar abstrakt respektive konkret tänkande affekt efter en positiv händelse? En experimentell studie i en studentpopulation

The aim of this study is to through six interviews, with six experienced, social workers?, in three cities, understand how the child?s position in the Swedish child protective services? enquiries has change, and the factors behind it. The aim is also to compare if the social workers? view of the child?s position in the enquire has change accordingly to Socialstyrelsens intentions of BBIC. The theoretical approaches that was used is the new institutionalism, the Shier?s pathways to participation and the term discretion.

Undersökning av luftkvaliteten vid småskalig biobränsleförbränning i två kommuner med modellsystemet VEDAIR

An Internet application, VEDAIR, for estimation of air quality in regions with small-scale combustion of bio fuel has been developed by Swedish Meteorological and Hydrological Institute with financing from Swedish Energy Agency and Swedish Environmental Protection Agency. The model contains user interface and a coupled model concept where concentrations of atmospheric pollutions are calculated for regional, urban and local contributions. In this report the model is described and a first study of air quality considering PM10 (particles with a diameter less than 10 µm) in two Swedish municipalities, Vänersborg and Gnosjö, is introduced.According to the result, there are areas with poor air quality even in smaller Swedish municipalities, mostly due to high emission from buildings with older wood heating furnace without hydraulic accumulator.In Vänersborg three areas were analysed in VEDAIR for the year 2003: Vargön, Mariedal and the downtown district. In the whole municipality the upper evaluation threshold for PM10, which is defined as 14 µg/m3 for annual average, was exceeded due to background contribution of particles. In all areas, however, the concentrations of PM10 were less than the environmental quality norms.

Pricing Credit Default Index Swaptions A numerical evaluation of pricing models

This study examines the background and nature of the credit default index swaption (CDIS) and presentsrelevant methods for modelling credit risk. A CDIS is a credit derivative contract that gives the buyerright to enter into a credit default index swap (CDS index) contract at a given point in time. ACDS index, in turn, is a multi-name credit default swap (CDS). Within the eld of research, thisthesis identi es the CDIS pricing models presented by Jackson (2005), Rutkowski & Armstrong (2009)and Morini & Brigo (2011) as the most recognized and developed. These models are evaluated byreconstruction in a numerical software environment.

Hur påverkas vård- och terapihundar av sitt arbete och hur uppfattar föraren hundens känslor?

Today's research on animal assisted interventions (AAI) has focused on the positive effects on humans. Dogs used for AAI are an expanding market, but the research on this area hasn't followed the increasing use. The few studies on dogs in this field mostly observed their cortisol-levels and are very ambiguous. I have observed the behaviour of dogs working with AAI compared to when they are off-duty to see how they are affected by their work. Their handlers where also told to make an assessment of the dog's emotions during the session.

Flexibel lärandemiljö: En studie av ett högskolebiblioteks lokalförändringar utifrån kunskapssyn och lärandeperspektiv

The aim of the study is to examine how different factors,such as views on how knowledge is produced and howlearning takes place, effect the way an academic librarymanages space. This is done by looking into how a specificlibrary, namely Library & Learning Resources (LLR) at theUniversity of Borås, by re-planning the building?s structure,design and functions, can support the students? differentstudying habits. The analysis is performed by using a theoreticalperspective built by a model first created by thearchitect Daniel Koch. The model is designed to look uponhow space produces meaning and knowledge.

Värdet av demand response på den svenska elmarknaden

Intelligent IT-based solutions, often called Smart Grids, are considered to be the future balancers of renewable energy sources. One area within the Smart Grid concept is called demand response, which is focused on making customers more consumption flexible by making them more active in their consumption. In this thesis the aim is to analyze a business model by investigating the income potential for a demand response solution as well as its market potential. This has been done through literature studies, interviews and development of a computational model.The use of 5000 households with flexible consumption can provide a cost reduction of 17.2% or 2.4 million SEK for a balance responsible party during an average year. If the solution is used to make strategic bids on the regulation markets the study indicates that the largest potential for revenues lies within this strategy.

Mobilt arbetssätt inom sjukvården och patientens personliga integritet : Klarar patientens integritet att journalen görs tillgänglig för sjukvården mobilt?

In the light of new technology health care is now given the opportunity to form a more mobile way of working that would bring about potential gains in terms of efficiency and quality. On the other hand, a more mobile health care also requires a more generous handling of personal information, something that may raise issues in terms of privacy. This study shows that the privacy of the patient requires two things: (i) that the personal information of the patient is handled in a way that generates her an overall positive expected utility and that (ii) the negative expected utility that each risk of an information leakage causes is offset by the expected utility it also makes possible. The first requirement (i) is shown, in comparison with today?s way of working, to be met due to the potential gains in efficiency and quality in combination with no increase in the probability of informational leakage or negative effects of such a leakage. The second requirement (ii) was also considered met since no separate risks of information leakage could be identified that was not offset by the gains it made possible in terms of expected utility..

Förekommer nedskrivningar av goodwill på Stockholmsbörsen i större utsträckning vid sämre redovisade resultat?

Background: Goodwill has always been frequently discussed and a lot of scientific research has been done regarding factors that affect companies? impairment of goodwill. Previous research has concluded that companies reporting low results are more prone to do impairments of goodwill than companies reporting better results which possibly can be seen as a form of earnings management.Purpose: The purpose of this essay is to examine if goodwill impairments occur to a greater extent among Swedish listed companies when the companies are reporting lower earnings. A subsidiary purpose is to see if there has been an improvement since 2008 regarding the size of reported goodwill in comparison to equity in the years 2009-2011. And to analyze the development of the companies goodwill impairments in relation to reported goodwill.Methodology: Three quantitative studies have been performed for the years 2009-2011 where all the listed companies on NASDAQ OMX Stockholm have been included.

Ett flervariabelt feldetekteringssystem för övervakning av bärlagertemperaturen i vattenkraftturbiner

The purpose of this thesis work was to develop an automatic fault detection system for surveillance of bearing temperature in hydropower turbines. The parameters used except the bearing temperature were cooling water temperature and cooling water flow. A simple static model based on data sampled every minute was developed to estimate the bearing temperature. Then a detector for detection of change in bearing temperature based on the CUSUM-algorithm was designed. Since the amount of data was very small the developed model was too uncertain to be used in a working system.The designed fault detection system showed to work well for the available data.

Att plocka russinen från kakorna : En studie om hur kuratorn inom hälso- och sjukvården arbetar med och utvecklar sin kunskap inom krisstöd.

This thesis aims to explore how medical social workers/counselors perform their workwith people during crisis and how they accumulate and practice scientific crisisknowledge. This study is an empirical research paper based on qualitative interviewsconducted with eight medical social workers. The data was analysed with Kvalesmodel for categorization, which constitutes the basis of the research. The results ofthe research was then analysed with the use of Cullbergs crisis theory and a model ofevidence based practice which is described by Topor and Denhov. The results showthat the medical social workers practice the evidence based practice model, describedby Topor and Denhov, in combination with Cullbergs crisis theory.

Kungsmarken, svart på vitt

Kungsmarken, a apartment area in Karlskrona has suffered the medias prying eye for decades. Today the area only maintains a very low position of status in the livinghierarchy in the community. The area in question was a part of the "Miljonprogrammet" and apperantly has suffered the same consequenses as similar areas since it was built. The onesided negative discourse that has persecuded areas of Miljonprogrammet, such as Kungsmarken, has put social problems as criminality, drugaddiction, dependancy on the social welfare system or cultural incompetence in the focus. The author´s previous understanding of the phenomena lies in private experience from living in Hjällbo, a similar area in Gothenburg also with the miljonprogram.

Biblioteksprofiler: kvalitativa fallstudier på tre folkbibliotek

The aim of this master?s thesis is to examine the roles ofthree different public libraries in three differentcommunities. In order to get some answers about the roles ofthe public libraries I have used the following questions: Howis the local cultural policy formulated? How is the locallibrary structured? What or which profiles has the publiclibraries in the three communities?I have made three qualitative case-studies in three differentcommunities. These three communities are somewhatlocated in the same area in order to identify any cooperationbetween them.

Validering av vattenkraftmodeller i ARISTO

This master thesis was made to validate hydropower models of a turbine governor,Kaplan turbine and a Francis turbine in the power system simulator ARISTO atSvenska Kraftnät. The validation was made in three steps. The first step was to makesure the models was implement correctly in the simulator. The second was tocompare the simulation results from the Kaplan turbine model to data from a realhydropower plant. The comparison was made to see how the models could generatesimulation result that was similar to the reference power station.

Institutioners inverkan på entreprenörsaktiviteter : En empirisk analys av relationen mellan institutioner och entreprenörskap

Entrepreneurship as playing a important role for economic growth has been discussed by a number of theorists such as Joseph Schumpeter and Israel M. Kirzner. William J. Baumol developed these theories as he considered that all entrepreneurship doesn?t lead to economic growth, some entrepreneurial activities may even lead to stagnation.
