Blodbad eller tragedi : Hur fyra skolmassakrer framställs i Aftonbladet och Dagens Nyheter

This survey's main purpose is to highlight how the two Swedish newspapers Aftonbladet and Dagens Nyheter writes and describes four different school shootings. We wanted to find out if there is a general pattern of how school shootings are reported by the media. Two of the shootings occured in USA, Columbine and Virginia Tech, and two in Finland, Kauhajoki and Jokela. The analysis aims at three areas: the whole event, the perpetrator and the victim. We have used a qualitative content analysis with a semiotic model to examine the articles in the survey. The theories in the study is based upon views on social constructionism, media logic, stereotypization, representation, morale panic/media panic and media events.

Moss-sedumtakets bullerdämpande egenskaper : The noise reduction capability of greenroofs

Syftet med arbetet är att få en förståelse för moss-sedumtakets bullerdämpande egenskaper. Jag kommer även att försöka förutsäga med hjälp av akustikteori vilken utav de två olika uppbyggnadssystemen av moss-sedumtak som ger den bästa bullerdämpande effekten.Mätningarna kommer att bestå i att registrera ljudtrycksnivån i rummet, vid varje oktavband i frekvensområdet 125-4000 Hz. Först utan moss-sedummattan och sedan med moss-sedum mattan. Storleken på differensen i ljudnivån ger en bild av i vilket frekvensområde som ljudabsorptionen är effektivast. För att ytterliggare öka förståelsen för hur moss-sedum absorberar ljud så kommer även absorptionsfaktorn att beräknas.

Robothandel ? En rättvis arena? -En litteraturstudie om Robothandeln med aktier

The purpose of the thesis is to demonstrate how high frequency trading affects the stock market. The growing high frequency trading is affecting the game plan on the financial markets and concerns have grown about the high frequency users intentions with their business. It is difficult to receive an overall picture of the subject because the lack of previous research and even the research that exist do not show the entire picture. The thesis contributes to the research through a comprehensive picture of the present debate as well as the previous research through a literature study. Our results showed that high frequency trading provides liquidity to the market, there is a statistical connection between high frequency trading and volatility, no price manipulation is being used and there is a need for a supervision of the high frequency trading..

Organisationskultur ur två perspektiv : En jämförande studie av två etnografier ifrån socialantropologi och organisationsteori

This study aims to compare two ethnographies of organizational culture ? one from the discipline of Social Anthropology and one from the discipline of Organizational Studies ? considering their purpose, their method, and their concept of culture. Despite big similarities, or perhaps thanks to the similarities, some fundamental differences are made visible. The discipline of Organizational Studies has, compared to that of Social Anthropology, regarding the research method being used, less focus on, and less participation in, the informal social life of the organizational culture of the study. Regarding the concept of culture the Organizational Studies consider culture containing more of unity, stability and clear boundaries, compared to Social Anthropology.

Vallfoderproduktion i norrländskt klimat till högpresterande hästar :

High-performance equine athletes have an energy requirement that often reaches twice the maintenance requirement. Horses are grazers and adapted to a grass diet, and diets high in grains and concentrates are associated with digestive upsets and behavioural disorders. It could therefore be of interest if the energy requirement of a high-performing horse could be met by forage. It is important that the forage have a high concentration of energy so that the horse is able to consume the whole amount of energy needed from the forage without exceeding the maximum voluntary intake. The purpose of this literature study was to investigate if the energy demand of a high-performance horse can be covered by forage produced under Northern Swedish climate conditions.

Ungdomar, religion & religiositet En undersökning om ungdomars syn på religion och religiositet

This is a study concern high school student?s view of religion and their religiosity. I dispensed a questionnaire to 124 high school students studying comparative religion in a large high school in Sweden, with the students from different socio-economic backgrounds. The result I came up with is that traditional religion activities have decreased, religion has not disappeared but taken other shapes than before. And I also came up to with the result that more than half of them who answered the survey likes the subject and there are tendencies by them who doesn?t like the high school subject religion that they live in a non-religious family.The study concerns following aspects: sociology, youth, human needs, religion, spirituality and individualization..

Ängar - att skapa ängskänsla i din lilla trädgård

Ett brinnande intresse för naturen i kombination med min pågående utbildning på trädgårdsingenjörsprogrammet med inriktning design gör att naturinspirerade trädgårdar är något jag både tycker är vackert och något jag ville lära mig mer om. Det här examensarbetet handlar om att skapa ängskänsla på ett litet utrymme, med vilda och hortikulturella växter. I arbetet beskrivs olika anläggningstekniker, skötsel för de olika anlagda ängstyperna, samt gestaltningsförslag för olika slags ängar. Min huvudfrågeställning har varit Vilka växter passar i en konstgjord äng i en liten trädgård, vilka ger stark karaktär och varför passar de växterna bra? Jag har valt att inte fokusera så mycket på historia utan ger bara en snabb bakgrund till hur ängar uppstod och varför de är intressanta i trädgårdssammanhang, detta behandlas mer i min litteraturstudie.

Vakuumbrytare i småskaliga vattenkraftstationer

This master thesis has been performed at Vattenfall Power Consultant in Gothenburg and Trollhättan for Vattenfall Vattenkraft. In this report vacuum circuit breaker in small-scale hydropower stations with the rated power 4 MVA and below has been studied. Models of the stations are modeled and analyzed in PSCAD/EMTDC to study the high voltage transients that are created after current chopping with vacuum circuit breaker. Vacuum circuit breaker may chop the current before it reaches zero value, which means that high voltage transients can be created. The equipment of the stations can be destroyed by high voltage transients.The purpose of this thesis is to examine the use of vacuum circuit breaker in small-scale hydropower stations and the risk for high voltage transients from current chopping.According to the results there is a risk of high voltage transients after current chopping with small synchronous generators in stations with the operating voltages 0.4 kV and 3.6 kV.
