Det smarta kapitalet : En studie av nyetablerade IT-företags syn på relationen till sitt riskkapitalbolag
Background: The growth of the venture capital industry has given birth to new relations between investors and entrepreneurial firms. Venture capital firms are by definition investors serving as an active partner which implies a deeper relation between investors and entrepreneurs than has been the case previously. This new situation leads to a number of questions. Do venture capitalists really act as active partners with a long term interest in the venture? Do they add any value besides capital? How important is their influence in the portfolio company's decision making process? Purpose: The purpose of this study is to give a deeper understanding of the relation between venture capital firms and IT companies in the start-up phase.
Vad är ?rätt? gjutkvalitet? Hur uppnås det?
Ever since ABB has begun diecasting their rotors instead of permanent mold casting it,variation in the quality of the cast has arisen. Diecasting is performed in three differentmachines, M1, M2, M3 with 400, 660 respectively 800 tons of die locking pressures.The aim of this thesis is to answer the following questions:What is the ?right? cast quality? How is the right quality achieved?For sizes 160-180 solutions will be proposed that consider eccentricity between thelaminate and the short circuit ring as well as elimination of the thin Al film that appearson the outer periphery of the rotors.Through considering the statistic material the most often diverging rotor type has beenidentified and one of the actual rotors has been sent to a laboratory to be analyzed inorder to establish the current defects. The result of the analysis shows that there areplenty of gas- and oxide-porosity.It has been proved that every time the dies temperature decreased below 120°C thecontent of gas porosity increased. It is due to rapid solidification of metal that flowsthrough the ?cold? laminate.It has confirmed that enhanced porosity in squirrel cage causes high impedance in therotors.
Barn- och ungdomars uppfattning om sin övervikt och fetma som ett problem samt skillnader i aktivitetsnivån hos barn- och ungdomar beroende på deras sociala familjesituation
BackgroundIncreased prevalence of obesity in children- and young adults and risk for diseases related to obesity will increase the burden on medical care. It is important to identify early risk factors that can be noticed by nurses in the daily work.AimThe aim was to investigate whether children- and young adults themselves perceive overweight as a problem and if there was a difference in the measured activity levels between overweight children- and young adults in families with different socio-economic family status.Method descriptionExisting survey from the Obesity Centre at the Akademiska Sjukhuset were examined together with the results from an accelerometer, where children- and young adults activity was recorded, compared to their perception of how active they were. The results were compared using a statistical software program and compiled with descriptive and non-parametric statistics.ResultsThe results do suggest that the majority of children- and young adults experiencing excessive weight have a problem in their everyday lives. Nearly half overestimate themselves as more active than what the actual measurements with accelerometer demonstrated. Much time is spent in front of the TV and computers.
Isavsmältningen vid Arktis : Arktis på väg att bli isfritt
Arktis är den plats där den globala uppvärmningen är som mest märkbar på hela jorden (Arktiska rådet). Därför är Arktis ett intressant område att studera ur klimatsynpunkt. Enligt Gore (2006) så kan en ökning av jordens medeltemperatur på 1,5 °C leda till att de ekvatoriala områdena får en temperaturökning på 0,5 °C medan temperaturen vid Arktis kan stiga med hela 6 °C. De senaste 30 åren har medeltemperaturen vid Arktis stigit med drygt en grad per decennium (Anisimov, 2007) medan den globala medeltemperaturen för samma period endast stigit med ca 0.15 grader per decennium.Arktis tros ha varit isfritt under en värmeperiod för ca 6000 ? 8500 år sedan (Founder, 2011) men det som är unikt med den aktuella situationen är att avsmältningen går så snabbt.
Fyra lärares tankar och syn kring arbetet med integration, mångfald och värdegrund på en mångkulturell skola
The purpose of this qualitative research study is to examine if and how the teachers from a multicultural International School work with intercultural pedagogy. The school in question isprofiled and consists of both Swedish- and English classes. The study examines if and how the teachers related to the great variety of cultures and created opportunities for integration between the students and handling with values at school. It is important to be aware as a teacher to be able to take an active part in working towards a school that gives possibilities for different cultures to meet. If this is neglected, it may increase the risk of problems and cultural clashes between the students.
Fysiskt aktiva skolungdomar : En studie som belyser högstadielärares motivationsarbete
SummaryAim and research questionsThe purpose of the study is to examine how physical education (PE) teachers can work to increase young people?s interest in physical education but also physical activity in general.- How can PE teachers work to increase student?s interest in physical activity?- Does PE teachers believe that the student?s interest for sports is achieved according to the educations curriculum and in that case, how?- What problems can PE teachers encounter in their efforts to get young people motivated for physical activities during PE classes?MethodPrior to implementation of the study i reviewed on a lot of past research and got interested about the problem with unmotivated students. After this I looked for different theories that I could use for my study and settled with the KASAM theory by Aaron Antonovsky. The method applied in this study was a qualitative interview method. The aim was to find out how teachers work to motivate their students to be physically active and wanting to participate in PE classes.

"The spirit of ayahuasca" : de kognitiva grunderna i erfarenheten av substansen ayahuasca: en fältstudie genomförd i Pisac, Peru
This essay aims at understanding the experience of the use of ayahuasca, and similarities and differences between interview protocols and socio-cultural identities. The work is based on field studies conducted in the Peruvian Andes, in the village of Pisac September to November 2009. What has emerged is that the experience does not seem to be dependent on cultural manifestations as much as it is dependent on general human cognition. Theories have been applied on an empirical phenomenological descriptive study. Various brain activities, along with mental mechanisms contribute to a deeper understanding of the findings in the descriptive analysis.It seems that the cultural differences, which I have classed as typological in the phenomenological study, mostly are expressions of meaning for the informants.
?Om man tar en tråkig bok så börjar den sova? : En kvalitativ intervjustudie av barn som läser för hundar i skolmiljö
This two years master's thesis examines the experience of children who read to a dog. The theoretical framework is inspired by sociocultural theory developed by Roger Säljö and the concept carnival inspired by Mikhail Bakhtin. The sociocultural theory has been chosen because it emphasizes the role of practice, instruments and communication in learning and the concept carnival has been chosen to analyze the experience of reading to a dog.The method used is qualitative interview and observation. A total of eight interviews and two observations when children read to a dog have been collected. One interview is with a teacher and seven interviews are with the children (six children participated and one child was interviewed twice).
Skoldemokrati : En kvalitativ intervjustudie som undersöker elevrådet och elevkåren som demokratiska forum för gymnasieelever i Stockholm.
The main objective in this study is to examine the pupil?s possibility to affect the upper secondary schools in Stockholm, Sweden. I was once active in the pupil?s council and experienced some hardships, feeling a great dissatisfaction among teachers and principals against pupil?s suggestions and chances to affect their school environment. Thus I wanted to do a contemporary study of where schools in Stockholm stand today within this issue.
Solenergi : en lönsam investering för ett lantbruk?
A possible way to reduce pollution and slow down the process of global warming is to increase the usage of renewable energy sources. One of these renewable energy sources is solar power. With the aid of solar panels and solar cells the energy from the sun can be transformed into both heating and electricity. The requirement to use the sun in this fashion is a suitable surface, for example a big roof, an angle between 40-60 degrees and that the surface should be exposed to the south. Almost every farm meets these requirements.
Motorik hos barn som går montessoriskola : En pilotstudie av elever på en montessoriskola i jämförelse med Skola, Idrott och Hälsa-projektet
AimThe aim of this essay is by using a motor skill track to see if there exists any remarkable difference in the motor skill profiles between pupils from our montessori school and the mean score in the "Nytidstest". The questions at issue we had were: How is the motor skill profile on pupils in year 2 and 3 practicing montessori pedagogy? Is the motor skill profile superior or inferior to the mean score in the "Nytidstest"? What factors, if any, concerning the montessori pedagogy affects the results of the test?MethodWe used a motor skill track consisting of 8 stations sellected from the "Nytidstest" adapted for year 3 (the original test consists of 16 stations). Pupils from year 2 and 3 in our chosen montessori school were tested in groups of 4-5 persons each. We made the tests on two occasions each lasting for 100 minutes at the time.

Verkligt värde : Hur verkligt är det egentligen?
Masters thesis in Business Economics IV, VT 2012Linneuniversity in Kalmar Authors: Johanna Susaeg and David JohanssonTutor: Petter BoyeExaminer: Karin JonnergårdTitle: Fair value - How real is it? Background and research discussion: The concept of fair value is today connected with great uncertainty, which may be a result of the various guidelines developed during recent years. Hence, auditors have an important role in situations where they have to make projections concerning fair value and also do inspections of the management´s own assumptions. The critique that has been shown regarding fair value is that it can be difficult to estimate, especially when there is no active market to proceed from. This problem has been confirmed through that the management often uses the estimations subjectivity to deliberately show higher or lower values in the accounts. Purpose: The purpose of this essay is to study and describe auditors, appraisers and real estate companys interest and procedure in valuation of real estates. We also going to describe theirs view on fair value of real estates plus analyze and explain the actor?s roles in the valueprocess and how their particular interests can affect the final valuation in different situations. Methodology: The study is characterized by a qualitative method containing a pilot interview and several personal interviews with auditors, estimators, and real estate companies.
Outnyttjade resurser inom park- och naturvård
As a small and land scarce country, effective waste management is ofoutmost importance in Singapore. In this study the production of biogasthrough anaerobic digestion from the organic fraction of municipal solidwaste (OFMSW) was compared to incineration of the waste. At the momentalmost all of the OFMSW in Singapore is incinerated. Three differentscenarios were compared to the reference scenario (incineration): one with alarge scale biogas plant that can treat half of all OFMSW in Singapore, onewith a medium scale biogas plant about 15 times smaller than the large oneand one with a small scale biogas plant that can treat waste from e.g. ashopping center or a food center.By using life cycle assessment (LCA) the different scenarios were comparedin terms of global warming potential (GWP), acidification, eutrophication,energy use and land use.
