Ledande indikatorers prediktionsförmåga på svenska aktiemarknaden : En empirisk studie om hur en investerare kan använda ledande indikatorer för sina investeringsbeslut

Att det idag finns flera metoder och modeller för att fatta beslut är inte konstigt då beslutsfattande sker varje dag och i vissa sammanhang kan ge ödesdigra konsekvenser om det blir fel. Denna kandidatuppsats kan ses som en förstudie för hur naturligt beslutsfattande skulle kunna stödjas genom en förbättrad utbildning till beslutsfattare. Uppsatsen ämnar behandla naturligt beslutsfattande och intuition hos experter inom räddningstjänsten, närmare bestämt om de använder intuition och i så fall vad som ligger till grund för denna intuition. Intervjuer utfördes på räddningstjänsten i Motala efter critical decision method som är framtagen för cognitive task analysis. Inom räddningstjänsten använder sig befälen av intuition när de tar det flesta av sina beslut i fält.

Fågelbär (Prunus avium L.) - överlevnad, höjdutveckling och skador i unga planteringar på småländska höglandet :

Plant survival, plant damage and height growth were studied in nine wild cherry (Prunus avium L.) plantations in southern Sweden established between 2000 and 2002. All stands were located to the county of Småland. The survey was conducted during May and June in 2007. During the survey the height, diameter and quality of the cherry trees were recorded. In one stand, red ? berried Elder (Sambucus racemosa L.) was a dominant species.

Vara och Kristinehamns folkbibliotek - en jämförelse av folkbiblioteken under år 1994

The aim of this essay is to try to find the differences and similarities of two public librariesin the town of Kristinehamn and the rural community of Vara during the year 1994. Especiallyinteresting was if the different political traditions of the two communities -left wing majorityin Kristinehamn and right wing in Vara- have influenced the forming of the public libraries.The comparison contains accounts from the annual reports produced by the libraries between1987 and 1994, a more thorough study of the activities and interviews with decision makers in1994. The interview with the decision makers indicates that there is a distinct difference betweenthe librarians and the rest of the informants, this distinction shows, that in a tight budgetsituation the librarians prefer not to cut down on staff while the other informants actuallyfavour to make cuts on the procedures handled by the librarians. The general opinionthough, is that they all agree that the role of the public libraries is to defend democratic rights.The final conclusion is that the material of this essay supports the opinion that the idea ofpublic libraries is stronger than the political differences in Vara and Kristinehamn..

Inuti den svarta lådan: En studie av beslutsprocesserna bakom EU:s gemensamma handelspolitik

Trade was assigned as a Community responsibility at the founding of the European Community in 1957. It was then recognized that Europe would achieve a greater international influence if it were to negotiate trade deals with one voice. Since then, the basic rule has been that the European Commission negotiates agreements on behalf of the EC, and presents the agreements negotiated for approval in the European Council. Today, the 25-member European Union is the largest trading power in the world, and most member states have decades of experience of coordinating their national trade interests into a common position. However, partly as a result of the complex nature of the trade decision-making processes it is sometimes problematic to identify who or what really influences EU trade policy.

Delat ledarskap, en gemensam resa

Introduction/Background: Economic evaluations help decision-makers to make informed decisions regarding resource allocation. Information generated from CEA can support evaluations of a new intervention with current praxis. The evaluations also provide information as to whether an intervention is cost-effective, both in economic terms and in health gains. Objective: The aim of this thesis is to investigate the use of economic evaluations in public health, with a focus on CEA. Use of economic evaluations is regarded as both a method for evaluation and as support for informed decisions.

Påskön. Myten om Rapa Nui

This essay will examine the historical picture of the island Rapa Nui as it is portrayed in popular science and in ecohistorical literature of the university of Gothenburg. This historical picture states that the inhabitants of the island cut down a lot of trees in the process of transporting the big and heavy statues, moai, from the quarry to the platforms along the coastline of the island. During this process all trees disappeared and resulted in soil erosion. The cultivation was destroyed and brought hunger to Rapa Nui. The following rivalry for food led to a situation of war followed by a cultural collapse.

Planering av väginvesteringar :

The problems around and the planning of wood flow is some of the most complex issues in the forest-sector. The experience and overview of the single employees is crucial for the possibility of correct tactical and economical decision-making. The increasing demand of savings and shorter reaction-times with greater flexibility in the wood-supply-chain, makes solutions and aids for improved effectiveness in the work and processes according to wood-flow urgent. Holmen Skog is starting to develop a new forest-road-management-system. The system will facilitate the work according to construction, improvements and updating the standard of roads.

Att återställa en naturlig ordning : skogshistoria och restaureringsbränning i Långsidbergets naturreservat

During the late 1800s fire suppression became increasingly effective in northern Sweden which led to decreased areas of fire-disturbed woodland and successive changes in the structure of forests. In the long run this can pose a serious threat to fire-dependent and fire-favored species. Today some fire-prone forest reserves are burned as a nature conservation act. Often partial cuttings are made before burning, with somewhat different motives. The purpose of the study in Långsidberget nature reserve was to give a general picture of forest history and its affect on today?s forest condition, and to show how partial cuttings affect burning conditions and results. Långsidberget is located close to areas that were colonized during the Middle Ages.

Röjning på snö och röjning på barmark : effekter på produktivitet och kvarvarande bestånd

Approximately 4000-5000 hectares, of SCA´s forest land area in Västerbotten, are in need of pre-commercial thinning (PCT) every year. Within the management district, the areas annually treated with PCT must increase, in order to decrease the area with an urgent need for PCT. This can be done by employing more forest workers or entrepreneurs, by mechanized PCT or by an extended season for PCT. Positive experiences from a private forest owner, who started to carry out PCT when the first snow came and then continued for several months, gave an idea to investigate the possibilities to prolong the season of PCT. The purpose of this experiment was to compare PCT carried out when there was snow on the ground with PCT performed when there was no snow on the ground.

Framkomlighetsanalys med hjälp av en digital terrängmodell och kartdata

Driveability analysis of terrain data offers an important technique for decision support for all kinds of movements in the terrain. The work described in this report uses a high resolution digital terrain model generated from the laser radar data and further processed by the Category Viewer program, and information from the Real Estate Map. Properties of features found in a filtering process are calculated and compared with a set of rules in a knowledge base to get a driveability cost. This cost is then visualized in a graphical user interface. An evaluation of what driveability is and what it is affected by is performed, and a general cost function is developed, which can be used even if not all relevant information is available.

Skärvor av en svit ? förflutenhetens plats i Hammarkullen

The present study examines the demolition of a house on Hammarkulletorget in 1996 and the discourse of Hammarkullen, Gothenburg(Sweden), drawn from the perspective of historicization [?historisering?]. I have examined how the past played role inpresentations of Hammarkullen and how the past affected the decision to demolish a house. By examining which role the neighbourhood?spast time played in the perception of the neighbourhood, the thesis aims at providing a better understanding of howthe past can influence and legitimize major changes in the urban environment.In the early 1980s the image of Hammarkullen as a victim of negative publicity is established and this reputation lives beyond thesimplistic and negative descriptions themselfs.

Avancerad scenarioanalys för ambulansplanering

This paper describes the development of a simulation model for the ambulance flow in the Västra Götalands-region of Sweden, and an analysis tool for the output of the simulation model. The aim of the simulation model was to be able to evaluate the outcome from changes in the ambulance operations, such as a reorganization of ambulances or an increase in intensity of the ambulance calls. This evaluation is meant to serve as decision support for the strategic planning of the ambulance operations. The analysis tool was developed to visualize the abundant geographical data produced by the simulation model in a meaningful way. The simulation model was validated against historical data which showed that the dispatch time for the highest prioritized ambulance calls corresponds well with historical data.

Skötselavtal eller sköta graven själv : vilka faktorer spelar roll vid beslut om gravskötsel?

This study is a first attempt to try to understand what the variables could be that make the person responsible for the grave sign up for grave gardening services by the church or to maintain the grave by him- or herself. There has been almost no research done within this subject. This study has been made by a qualitative research method and interviews have been performed with both persons responsible for the grave who have gardening services made by the church and with those who maintain the grave by themselves. The characteristics that are affecting consumer behaviour and the buyer decision process are presented in the theoretical part of this study. That is done so it can be seen if a comparison between the results of the study and the basic theoretical concept is possible, resulting in an understanding of how the costumers think and argue about this question.

Big Data. En undersökande studie om hur Big Data uppfattas hos IT organisationer i Sverige

Data sets are continuously increasing within organizations. Data sets will also be in larger amounts,have shorter lifetime, is becoming more varied and holds various degrees of uncertainty. Together,these dimensions are included in the term Big Data. There is no universally accepted definition ofBig Data and how it should be used. Applications that turn out to be part of a Big Data conceptoften begin as investments in an organization in order come to new insights or create new businessperspectives.

I domstolens fälla? Den Liberala Intergovernmentalismen från Utstationeringsdirektivet till Lavaldomen

This thesis aim to advance the Liberal Integrovernmentalism (LIG) developed byAndrew Moravcsik in order to order to explain how the European Court of Justice (ECJ) can make de facto EU policies diverge from what was originally intended by the Member States. More specifically it describes how the Posting of Workers Directive, Directive 96/71/EC, originally was created to shield certain Member States and their respective systems of regulating the labour market from pressure arising from the posting of workers form low-wage countries inside the EU. However, through a series of cases in the ECJ the de facto policy of the directive has changed and it is now in itself a potential threat against these systems. The Member States now find themselves caught in a ?Joint-Decision Trap?, unable to rectify the situation even though their original agreement has been turned on its head.
