Manlig omskärelse : Föräldrarnas eller barnets religionsfrihet?
Bullying is today a major problem in schools worldwide. Far too many children are forced to undergo bullying day in and day out without anyone seeing or doing something. My purpose with this study is to find out how four F-6 schools in a municipality south of Stockholm are describes their work to get zero tolerance for bullying at their school.My questions are:How does the four F-6 schools' anti-bullying group in a municipality south of Stockholm describes their work to have zero tolerance for bullying?What do the employees in the school anti-bullying groups consider that bullying is?Why do the employees in the school anti-bullying groups think bullying occurs?Who do the employees in the school anti-bullying groups think are bullies or are being bullied?To get my results I have done four interviews with those in charge of the school's anti-bullying group. My theory is based on standards, what is acceptable behavior and normative theory, hypotheses, what is right and wrong as well as desirable or undesirable behavior.
Postoperativ shivering: En kvantitativ studie om dess orsaker
Postoperativ shivering (PAS) definieras som en serie ofrivilliga muskelrörelser som ökar den metabola värmeproduktionen i kroppen. Förekomsten av postoperativ shivering är ett problem inom den perioperativa vården. Det finns flera orsaker till shivering. Termoregulativa och icke termoregulativa. PAS förekommer i ca 5-65% av alla anestesier, men frekvensen har under åren minskat.
Nya träd för stadsmiljö
Trees in urban environment are exposed to extreme conditions, foremost the ones that grow in the hard packed soil along our streets. They are also exposed to damaging insects and fungal diseases both local and new ones spreading from South Europe. The global warming with warmer temperatures provides a longer growing season, making it easier for insects and fungus to establish a habitat. Based on these facts new tree species need to be available for future urban plantings.To determine what these trees would be an interview study began. Six people were selected who have experience in the field of urban environment planting.
Projektorganisering : En fallstudie av Östers IF?s nya fotbollsarena
Background - The trend of new soccer stadiums took off in England and the three key factors of this trend where security, economic value and growth. In the early 2000s the trend came to Sweden and Växjö. The soccer stadium, Värendsvallen were old and needed modernization.Purpose - The overall purpose of this study is to understand how Östers IF as a nonprofit organization has organized themselves when planning a large and complex project as the construction of a new soccer stadium. It also aims to portray how Östers IF has moved from concept to reality with the new soccer stadium.Method - The case study of the project organization in Östers IF where made ??using semi-structured interviews and participant observations.
Åre kommun och klimatförändringar : En studie kring hotet mot Åre kommuns vinterturism och dess anpassning till framtida klimatförändringar
Today?s climate research shows that the climate may increase its temperature. One sector that is being threatened by global warming is the winter tourism of the Swedish municipality A?re. Tourism is an important economical source of income in A?re and is now threatened by a shortened winter season.
Flyktingungdomars upplevelser av deras etniska identitet
The aim of this study has been to reach a deeper understanding of how refugee adolescences experience their ethnic identity, particular ethnic consciousness in terms of integration, assimilation and segregation. Further my intention has been to investigate if the adolescences experienced changes in their ethnic identity. In order to investigate these questions a qualitative method consisting of four interviews were conducted. The study included two young men at the age of 18, and two young women at the age of 17 and 18. Three of the interviewed persons can be defined as refugees, but not the fourth adolescence.
Uppförsäljning - en väg till ökade snittköp
The Swedish consumer electronic industry has recently experienced an increasingly intensive price war. The price war has forced some operators in the business to declare bankruptcy, as the only way to compete has been by driving down prices. A challenge that retail chains in the consumer electronics industry is facing is to increase their margins. If store personnel can success with upselling, the companies will increase their profits. The purpose of this paper is to examine if the sales people in the consumer electronic industry can influence the customer to buy a more expensive product and what the effects the upselling has on the customers' attitudes.
Lätta människor, men svårt språk! : En studie av flyktingars upplevelse av integration.
The aim of this study was to explore refugees experiences of an introduction program in a small Swedish municipality. The study was based on semi-structured interviews with six refugees and was conducted to explore how the introduction program contributed or has not contributed to feelings of being integrated. Our informants have got different backgrounds but have all been forced to flee their home country to Sweden. The interview data was interpreted through earlier research, theories about social exclusion and concepts which were relevant for our study. Our study showed that the informants felt kindly received in the small municipality.
Att författa en Design- en processorienterad fallstudie av manusförfattandets arbetsprocess i ett interaktionasdesignarbete
This thesis is a process oriented case-study. The studied case is a interactiondesignassignment of a databasevisualisation and the process. The goalis to do this according to the ways of a screenwriter.When the computers spread from the military and university's into homes all around the world the computers and the programs had to becomeeasier for the users to understand and use. User interfacedesign became more and more important and companies like Apple put a lot of resources intothe designprocess. This quite new and evolving area of research, interactiondesign, has been forced to search for methods in other areas like lm, gamedesign, psychology and behavioural science.
Ny teknik för småskalig kraftvärme : - med fokus på Organisk RankineCykel (ORC)
As a part of the fight against the global warming the energy production needs to be more efficient and redirected towards sustainable options. One alternative is cogeneration, which means that electricity and heat is produced in one plant. The purpose with this survey is to examine if there are any commercial available combined heat and power techniques, based on combustion of solid moist biomass, which are suitable to small-scale applications. The technique must be able to produce between 2 and 10 MW thermal and the heat demand is a Swedish district-heating system. When already published reports had been studied, the Organic Rankine Cycle (ORC) was chosen as the most suitable technique.
My patience ran out on Hasad a long time ago? - varför blev Syrien en ondskans axelmakt?
In 2002 George W. Bush held a speech where he classified six nations as being the main threats to American security, one of them being Syria, a state with a secular constitution, no resent offence towards the US, and with an improved diplomatic relationship to the US during the Clinton years.Being an ally to the Soviet Union during the Cold War Syria was forced to redefine its role in the region. Using neorealistc theory one part conlusion is the fact that the new Syrian leader, Bashar al-Hasad, in the early 21th century determined to set higher goals for the Syrian power ambition in the Middle East, threatened to destabilize the region and leave the US and its allies in a caotic situation.In the US, however, the new administration after 11/9 sharpened its tone towards states that did not cooperate in the new ?war on terrorism? or/and were likely to harbour terrorists. Syria was accused of doing both.
Omkonstruktion av kolvlod : På uppdrag av institutionen för geologiska vetenskaper Stockholms universitet
On ocean beds around the world sinking particles of residual biomass from animals and vegetation have, over time, accumulated into thick layers of sediment. For researchers these layers of sediment contain valuable information about the earth?s past climate, information that can be used to predict future climate change and to estimate natural vs. human causes of today?s global warming.The Institute of Geosciences at Stockholm University studies sediment cores that have been acquired with an apparatus called piston corer.
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.
Robotstyrning med metoden Sliding Mode Control
The task in this thesis is the steering of one of Saab Bofors Dynamics robots using Sliding Mode Control, a method they never used before. The robot constitutes a system which in addition to perturbations and uncertainties due to modeling imprecision, hold the difficulty of being highly time variant. In order to be able to keep required performance with uncertainties and modeling imprecision present, the use of robust control methods like Sliding Mode Control is necessary. SMC is based on the states of the system being forced to stay on or in the direct vicinity of a hyper plane in the state space which is chosen in a way that gives the system dynamics desired properties. Other advantages with sliding mode are reduced order dynamics on the switching surface and total insensitivity to some uncertainties and perturbations.
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.
