Val av outsourcing-leverantör. En fallbaserad studie av hur organisationer väljer outsourcing leverantör.
This report explores how organizations act when they are choosing an Outsourcing supplier. The study was conducted through multiple interviews with managers of different organizations. The data from those interviews was then analyzed through the use of two theoretical models. Our findings indicate that most organizations share the same base factors (qualifiers) when selecting an Outsourcing supplier. What therefore become crucial are the key factors that the Organizations see as Order winning factors.
Syntes och egenskapskarakterisering av volframoxid framställd med magnetronsputtring
The system tungsten-oxygen has potential of being suitable for decorative coatings since ceramic coatings are often hard and wear resistant, and since modulations in oxygen content or incorporation of small ions could give bright colours. The aim of this report was to investigate the relationship between process parameters and the properties of the films, with the wear resistance being of special interest.Samples with tungsten to oxygen ratios in the range of 100:0 to 25:75 at% were made using reactive sputter deposition, either with constant gas flow, or gas flow controlled by optical emission of the plasma. The hysteresis of the system, which means that a certain gas flow will cause different pressure and/or target voltage depending on in what way the flow is reached, makes it interesting to control the process where the system makes the steep change from metallic tungsten to ceramic tungsten oxide. This is difficult and thus requires precise control equipment.The samples were analysed using X-ray diffraction, X-ray photoelectron spectroscopy and an empirical wear test suitable for small components like cell phone cover for example, in order to characterize the structure, composition and wear resistance of the coatings. The results could be divided into three groups: (I) tungsten-like, with very low oxygen content; (II) mixed phase and (III) tungsten oxide like, with oxygen content close to 75 at%.
Den globala uppvärmningen : vad kommer att hända med morgondagens värld?
Mankind faces a serious threat. Its activities, for example the burning of fossil fuels, have led to an enhancement of the greenhouse effect - something that has given rise to a global warming. The climate is becoming warmer, a change that has important effects on the nature as well as for humans and their society. Sea level rising, extreme temperatures are becoming more common, glaciers and other ice caps melt and storms becomes more intense when they appear. The main cause is the emission of greenhouse gases into the atmosphere - carbon dioxide in particular.

Kan företag tvingas till tillväxt?
The purpose with this disertation is to find if there are selected factors which can force companies to grow. We have chosen five factors which we think can force the companies; market, strategy, profitability, demographic and institutional factors. We want to examine if there are differences between small and larger companies, and if there are differences between the lines of business.The intention to growth is also influenced by different factors. The organization and the board have an effect on the development. There are also factors that can obstruct the growth, for example control.
Gymnasiereformer - en jämförelse av politiska argument : En jämförelse mellan gymnasiereformerna 1963 och 2009
The purpose of this paper is to examine witch factors lays behind political decisions when reforming upper secondary school. Three major factors are used: political, economical and structural. These factors become visible by comparing the school reforms 1965 and the coming one in 2009. An analytical scheme is used to find the factors in the primary information. The study is based both political inquiries and on debate articles from newspapers and political papers.The results show that two factors are more visible than the third, and that is the ideological and structural.
Att förstå ätstörningar : En kvalitativ studie baserad på kvinnors egna berättelser om hur det är att leva med ätstörningar.
The aim of this study is to create a deeper understanding of the disease known as eating disorder. The study is based on four autobiographies written by individuals who themselves have been affected by eating disorders. These stories have been studied using a narrative approach. To achieve the purpose, the study is focused on what participants describe as the factors underlying the onset of the disease, the factors that participants describe maintained their eating disorders, as well as what is described to be the factors responsible for their recovery. By my interpretation of the stories, I have been able to identify common factors that all participants describe to be influential in their disease course.
Utvärdering av koldioxidmätaren Vaisala GMP343 samt sambandet mellan grundvattennivå och koldioxidavgång från torvjordar
The research group Soil and Water Management at the department of Soil and Environment at theSwedish University of Agricultural Sciences in Uppsala are studying greenhouse gas emissions fromcultivated peat soils. To measure carbon dioxide emissions from peat soils in the field the researchgroup are now using two portable carbon dioxide meters (Vaisala GMP343). For practical reasons,they plan to acquire a new type of automated field meter. The aim of this study is to evaluate thepresent meters to see how environmental conditions and instrument settings affect the results,which is meant to facilitate the introduction of the new field meter when the meters needs to becompared. As a part of the study the relationship between groundwater level and carbon dioxideemissions from peat soils will be investigated.The evaluation of the two carbon dioxide meters was made by connecting them to one single airtightsystem, with the aim of creating identical measurement environments.
Hur lokal bioenergi kan bidra till att Uppsala kommun når klimatmålet 2050
The purpose of this thesis was to examine how locally produced bioenergy may contribute to meet the climate target year 2050 in the municipality of Uppsala. The
goal of reduced GHG-emissions from current 6,8 ton CO2-equivalents to 0,5 ton CO2-equivalents per capita and year, year 2050 is based on avoiding harmful penalties
of an increased level of GHG in the atmosphere. By estimating available biomass in the county together with examining future technologies and Emission factors for the substrates used, four possible future scenarios has been developed focusing either on electricity generation or production of biofuels. GHG-emissions of year 2050 have been calculated using the software LEAP.
The conclusion is that bioenergy, depending on how it is integrated in the energy system, may reduce greenhouse gas emissions between 0.6 ton CO2-equivalents and 1.4 ton CO2-equivalents per capita or 12% to 25% compared to 5.5 ton CO2-equivalents in the reference scenario 2050. The greatest reduction is obtained if biofuels are produced in combination with energy efficient heat requirements in
buildings..
Entrepreneurs? work with Factors for Success in a Start-up Business
The purpose of this study is to examine whether there are any key factors for success to look for in launching a new business that affects the subsequent performance of the venture. Further on, the study will examine if there are any differences between believed and actual factors for success for an entrepreneur and the key factors for success given by existing theory. The purpose of looking in to the assumed gap between existing theory and entrepreneurs? believed and actual factors is to distinguish factors that make start-ups evolve. It is then important to investigate how they have worked with their business start-up and how they have worked with key factors for success in order to understand the impacts of their decisions.
Lika bolag leka bäst - En studie om betydelsen av likhet vid sammanslagningar av bolag
This study addresses the issue of mergers between consulting firms. Previous research has shown that there are specific factors that determine the outcome of a merger and that success is more likely if companies are more similar. The purpose of the study is therefore to define relevant factors and understand when resemblance matter and under what conditions disparity may cause problems. Furthermore, the aim of the study is to find a pattern of which factors are more important in a successful merger. The problem of the study is addressed through a qualitative research approach and is conducted on six different mergers.

The purpose of this essay was to study factors that influence some youth to use narcotics. I wanted to increase my understanding and knowledge about these factors. I believe it is good to have such knowledge when you are working with youth who are using narcotics but also for a good drug-prevented work. It is a literary study, which covers the most frequently quoted results in the field of research.The questions for my study were:· Which factors influence youth to use narcotics on a individual level?· Which factors influence youth to use narcotics on a group level?· Which factors influence youth to use narcotics on a society level?My conclusion of this study was that youth often use narcotics because of many different factors and it is youth from all social groups in the society who are testing and using narcotics..
Miljöanpassad offentlig upphandling: effektivt styrmedel mot koldioxidutsläpp? : En studie av kostnadseffektivitet, transaktionskostnader och teknisk utveckling
Green public procurement (GPP) can be used as an instrument to reduce carbon dioxide emissions, and consideration of environmental aspects within public procurement is becoming more common in Sweden and internationally. Two product groups that have been pointed out as especially important are transports and electricity, where the opportunities for public purchasers to reduce emissions are relatively large. This paper studies GPP which aims at reducing emissions, primarily of carbon dioxide, through environmental requirements within these two product groups. A theoretical analysis of cost-effectiveness, transaction costs and effects on technological development is performed, followed by a closer study of how these aspects appear in practice within GPP.
The results indicate that a cost-effective allocation of reductions between the two product groups is most likely to be attained if the main part of emission reduction is achieved through environmental requirements on electricity. The cost for emission reduction within transports is relatively high, especially for heavy transports.
For transportation services, more generally focused requirements on emission reductions could probably give greater environmental gains, but the existence of transaction costs steer the environmental requirements towards more technology specific types.
