Strokekedjan från början till slut : En etnografisk studie om farlighet och tid i en akut vårdkedja

Varje år drabbas 30 000 svenskar av stroke, vilket innebär stora personliga omställningar och stora kostnader för samhället. Den mest effektiva behandlingen, trombolys, måste ges så snart som möjligt för att ha god effekt.  Samtidigt som det är av största vikt att ta reda på om patienten har några differentialdiagnoser som gör behandlingen riskfylld.Den här studien undersöker hur strokekedjan går till och vilka faktorer som påverkar beslutsfattandet. Studien är baserad på etnografiska fältstudier på fyra svenska sjukhus och materialet är analyserat med metoder från sammansatta kognitiva system och målorienterad design. Resultaten visar att trots olika organiserade strokekedjor på de olika sjukhusen är processerna desamma och direkt kommunikation är mest framgångsrik för att effektivt sprida information mellan dem. Neurologjouren är viktig roll som, liksom resten av aktörerna i strokekedjan, ständigt balanserar sitt beslutsfattande mellan effektivitet och grundlighet.

Konceptuellt ramverk för lagerlokalisering : ? En kvalitativ studie om lagerlokalisering

Bakgrund: Globalisering har gjort försörjningskedjan till ett komplicerat nätverk med många påverkande faktorer. I försörjningskedjan är valet av anläggningars position viktigt för att företag ska behålla sin konkurrenskraft. Valet av lagerlokalisering har stor påverkan på ett företags framgång.  Problem: Lagerlokalisering är en komplex process med många faktorer som påverkar, att praktiskt tillämpa existerande modeller är komplicerat. Det saknas ett konceptuellt ramverk för lagerlokalisering. Syfte: Syfte med examensarbetet är att skapa en konceptuell modell för beslutsfattandet för lagerlokalisering för mindre företag, att finna relevanta faktorer samt att praktiskt göra en förstudie för ett företag med verksamhet i Norra Europa.

Ungdomars mognad, en avgörande faktor : en kvalitativ studie inriktad på en grupp föräldrar gällande tillhandahållande av alkohol till sina barn

Our purpose was to shed light on how parents act in respect of providing alcohol to young people when they ask for a taste of home, or wish to bring alcohol to such a party. We used qualitative interviews and the results show that some of the respondents think that it may be acceptable to provide alcohol, while some do not. The results also show that the respondents think that parents are important as a model for the young. They could not purchase alcohol for the purpose of giving it to the young but only if alcohol is available at home. The reason for this behavior is the parents' assessment that the young person demonstrates a level of maturity for his age that they are presumed to be able to handle a small amount of alcohol.

En fordonsförares upplevelse av accelerationer som grund för en effektiv simuleringsmodell

Saab Aerosystems has a long tradition and a lot of competence in the field of flight simulation. Their ambition to broaden the market horizon has led to a discussion about also selling vehicle simulation solutions, both for military and civilian use.The aim of this thesis is to investigate the driver?s experiences of the accelerations he or she is exposed to whilst driving in rough terrain. The results may be used as a basis for future decisions and can act as a platform for the construction of an effective simulation model.To investigate the driver?s exposure of acceleration, some kind of dynamic simulation is needed.

Vägval: kortast, snabbasteller hälsosammast : En försöksmodell i GIS för ruttoptimering och beräknad inhalation av luftföroreningar för cykelrutter

Cycling is one of the most sustainable transport modes available and it is widely promoted inmany urban areas. The health benefits from cycling has shown to be substantial, includingdecreased risks of diseases related to overweight and enhancing brain capacity. However, inurban areas cyclists can temporaly be exposed to high levels of air pollution, resulting inhealth risks as opposed to health benefits.The objective of this thesis is to develop a rasterbased test model in GIS that estimates theinhaled dose of air pollution for cyclists based on relative particle concentration in differenttransportation micro-environments. The method used is a least-cost path approach,calculating three different routes; shortest, fastest and least dose for four different trips withinSödermalm, Stockholm.The results show that the inhaled particle dose can be greatly reduced, 39% - 58% for three ofthe routes, by choosing the least dose route. One of the most interesting findings is thesubstantial increase of dose when high levels of particles are combined with uphill cycling.The conclusion for the thesis is that a raster-GIS model can be very useful for estimating doseof different air pollution particles and chemicals along cycling routes.

Synchronizing migration with birth: an exploration of migratory tactics in female moose

Migration and giving birth are crucial decisions for animals during their life cycle, which may have lasting consequences on their population demography and fitness. Migration can entail a variety of possible effects for an individual, such as access to high quality food and reduced risk for predation. The moose (Alces alces) in northern Sweden is partially migratory and moose females are known to give birth to one or two calves. The synchrony between time of calving and timing of migration has not been compared before, especially in terms of energy maximizing and time minimizing perspectives, which may provide vital cues for fitness benefits of migration. I investigated effect of timing of birth and individual life history on distance, timing, stopovers and duration of 190 individually marked female moose that have been tracked for multiple years in ten different areas in northern Sweden.

AbstractRunning an individual bookstore is not an easy task. And then to do it in a profitable way is even harder.In this study you will read about what matters to the profitability in a bookstore. There are several aspects of this but it may be of interest to know what is affecting most of a bookstore's profitability.These three theories were researched by examination of previous research. The theories were then compared to the empirical research of an individual bookstore. Developing the empirical research qualitative and quantitative data collection methods was used.

Macedonian agriculture : preconditions for development of the agro-sector in Macedonia towards EU accession

The focus of the thesis is: how conditions for agriculture in the Republic of Macedonia today may form the basis for development of the agricultural sector towards conditions needed for future accession into the European Union. The method for investigating this question has been to look at newly available farm monitoring system (FMS) data from Macedonia. Also to look at the latest government policies created in the country for the agricultural sector and rural areas in relation to the requirements for EU accession. Articles and empirical studies published by other authors related to the questions which arise in this study have been reviewed and presented herein. Trade relations, trade patterns and national economic and agricultural trends are displayed to provide a background overview for the study of the agricultural sector.

TV-stativ med nytt ställdon

The purpose of this thesis work is to evaluate how the physical behaviour of a pipe bend is affected by the pipe bending procedure. Effects such as initial ovalization, thinning, thickening and plastic hardening from the bending procedure are examined and the mechanical properties of pipe bends containing these effects are investigated.This has been evaluated by creating a detailed Finite Element model of a pipe that is being bent. Then the differences compared to a bent tube in a virgin state, so called Elbow elements and an analytical in-house program have been evaluated. The virgin state refers to a model of a pipe that is bent from the beginning, thus having a homogeneous thickness and not containing any plastic hardening. The Elbow element is a calculationally cheap element, specially developed for accurate calculations of pipe bends in an initially virgin state.The goal with the thesis work is to get a better picture of what happens to a pipe as it is being bent, how this affects the mechanical properties and to evaluate the possibility to develop an easy method for taking these effects into account when using the Elbow element.This report describes the layout of the work and how the detailed FE-model has been constructed.

Klient-server och Peer-to-Peer applikationer : En prestandajämförelse

An increasing number of applications are becoming more or less network based today.The traditional architecture for network based applications is client-server, but as usageof download services are going up, so is the Peer-to-Peer architecture. This report is acomparison between the Peer-to-Peer and client-server model, and can serve as a basiswhen a decision between them needs to be taken. In the report, the performancebetween the different architectures is compared in different contexts. Our basis is ageneral implementation of both architectures in a test that is derived from a previousreport. On top of this, the performance of the different architectures are measured,implemented in a gaming-context.

Gröna transportkorridorer

The economic development and competitiveness in Europe is heavily dependent on an efficient transport system. Movement of goods and people is essential for a competitive industry and successful trade. As a result of an intensified transport business, consumption of fossil fuels has increased dramatically. As a consequence, there are increased emissions of dangerous greenhouse gases. Transports are often mentioned as an area with high impact on the environment.

Design av interaktionsmoment för spelarmotivation

The game industry is growing by every year but for some reason the research surrounding it hasn't caught up with its rapid expansion. This study aims at expanding the knowledge surrounding one of those areas, player motivations. An empirical model has been used to identify which interaction has the highest impact on player motivation in story-driven roleplaying-games. By conducting semi-structured interviews with eight different game developers using the GameFlow model to explore the use of interactions to sustain the motivation of the player a new criteria has been identified. This additional criteria was: Alive, and it was shown to have a high impact on motivation in story-driven roleplaying-games.
