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.
Aktievärdering : En studie om vilka aktievärderingsmodeller som främst tillämpas av finansanalytiker inom bankväsendet
Introduction: Analysts worldwide valuates stocks and companies by using different valuation models. The models are used to calculate how much public company?s stocks are worth and to identify whether stocks are over- or undervalued. Objective: The objective of this essay is to study which valuation models are mainly used by financial analysts in Swedish banks. The purpose is also to study how reliable these models are considered. Method: The empirical study is based on a qualitative approach through interviews with financial analysts. The study includes both primary data (interviews) and secondary data (literature, websites and scientific articles)Theory: The theory chapter includes methods of analysis (fundamental and technical analysis), Valuation models, components of valuation and an example of a valuation with the Discounted cash flow model. Empirical study: The study includes a qualitative research that consists of interviews with financial analysts.
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.

BIM-projektering i praktiken
The use of CAD, within the building industry came strongly, during the 1980?s and the 1990?s. The development has since then rapidly progressed and the using of 3D-models has in addition increased. We are now at the edge of next step of evolution. BIM, Building Information Model(ing), is here.
Bokhandeln : En studie om lönsamheten i en enskild bokhandel
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.
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.

Safe in the cityscape? Gender aspects on spatial city planning
In this thesis, theories regarding gender and spatial planning are applied to the comprehensive plan Fortuna och Hemgården in eastern Malmö. Independent of factors like class, ethnicity and age women experience lack of safety to a larger extent than men do.
Today, safety aspects on housing projects is scarcely a controversial issue, quite the contrary. However seldom are the central terms such as safety and security defined. Research has shown that women feel safe when they experience little risk of being subjected to violence; security is deeply interconnected with feeling safe.
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.
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.
Smarttelefon-sensorernas möjligheter - En studie om barometer-, GPS- och accelerometersensorer. The smartphone sensor possibilities - A case study featuring the barometer, GPS and accelerometer sensors
Denna rapport sammanfattar resultat av ett examensarbete på en högskoleingenjörsutbildning
som utfördes av två studenter på Malmö högskola.
Arbetets syfte var att genomföra en mängd olika experiment med accelerometer, barometer
och GPS i en modern smarttelefon. Ett antal scenarier för en tänkbar sensoranvändning i applikationer
formulerades för att vägleda olika experiment. Experimentdata dokumenterades noggrant
och analyserades med avsikten att skapa en databank med information för framtida studier.
Analys av data inkluderar höjdbestämning i naturen och i byggnader med hjälp av barometersensor,
geografisk position med hjälp av GPS, hastighet och acceleration under en hissfärd
med hjälp av accelerometer.
Rapporten innehåller en omfattande litteraturstudie om användning av sensorer vid inomhuspositionering.
Från analys av mätdata, kom vi fram till slutsatsen att är möjligt att beräkna höjden
från barometerdata med bra noggrannhet under optimala omständigheter. GPS höjden
från mätningarna har stor felmarginal jämfört med den verkliga höjden samt när den jämförs
med den beräknade höjden från barometern.
Genom att utföra en numerisk integration på accelerometer-data kom vi fram till att det är möjligt
att beräkna ungefär hur långt man har färdats med en hiss, dock att vissa detaljer måste tas
i beaktning..
Hot, våld och trakasserier : En studie om handlingsutrymme, politiska ledare och demokrati
Studies have shown that politicians are significantly more likely to become victims of violent crime than other citizens in Sweden. In fact increasing political rank and engagement are directly proportionate to increased risk for violence. Threat towards politicians is not only dangerous to the individuals involved but also to the democratic system as a whole.Political scientists the world over have done a lot of research on democracy, but I have been unable to find a single method or theory that examines how violence, threat and harassment affect political leaders and democratic systems.The aim of this study is to expand the existing model made by Tommy Möller, professor in political science. In his model he presents 11 factors that affect political leaders ability to act. My aim is to develop his model by adding a 12 th factor ?violence, threat and harassment?.
Behovet av en genomtänkt kommunikationsstruktur- en studie av ett projektorienterat företag
Every organization goes through the same lifecycle. Through every step in the transformation to a better organization the communication structure changes. In this report there are examples of the communicational disadvantages that is connected to the communicational structure.By choosing to not have a formal communicational design, the manager takes a risk in spreading the information, the interaction, the control and the balance in creativity and constraint.This case organizations problem is that some parts of the organization has made more progress in the communicational structure than other parts. In this case the Collectivity structure has met the Formalized structure.Tha structural differences has came to affect the way of sharing information and it has become a situation where the information about the products is not stored in a safe way from a quality point of view. There is a gap between the two different ways of communicate.In this report I have created a model to identify problems in the communication structure.
