This qualitative study is about the differences and similarities between the organization Friends and schools? methods to prevent bullying. Aggression, bullying and discomfort in schools result in that many students do not dare to go to school because of their fear that they might get attacked and become systematically bullied. Bullying is a universal and persistent problem. In this study the reader will receive a better understanding and get an insight into the problems that teachers and students experience and struggle with every day in dealing with bullying in schools.

Experimentets art och roll i naturvetenskaplig undervisning är ett fundamentalt och omfattande ämne. I föreliggande litteraturstudie görs ett försök att sätta in frågan i ett historiskt, pedagogiskt och vetenskapligt sammanhang. Innan experimentets roll diskuteras, ställs dock frågan vad naturvetenskap är, varför och hur det skall undervisas, och vad som kännetecknar praktiskt arbete och experimentell verksamhet i skolan. Med denna bakgrund refereras några forskares och lärares erfarenheter och åsikter. Det visar sig, föga överraskande, att formerna för och avsikterna med experiment i undervisningen är skiftande.

The aim of this thesis is to study the teaching methods that provide the greatest learning effect for children in grades 6 in the subject of Physics. One class was divided into three equal groups, each group was educated in a specific way. The three teaching methods that have been investigated are: film with reflection, laboratory work and traditional lecture- teaching. The research question of the study is: "Which method of three selected, causes the greatest understanding of the properties of air??.

Survey's purpose is to illustrate why and how the process happened when Piteå relocated its commercial port away from Skuthamn to the new construction on Haraholmen 1950-1973. How decision-makers worked to achieve their goals, how the work changed and what incentives motivated them to act. The results showed that the decision was taken not to retain the existing commercial port in large part due to Skuthamns Physics attributes, which made it impossible to ship large deep vessels from there. The reason that the decision about the port took such a long time was due to a local political conflict which was based on interest in the ownership of Haraholmen. The reason for the location of the trading port became Haraholmen had political backgrounds.

Organic Light Emitting Displays (OLEDs) are a new type of thin emissive displays predicted to possess superior properties to existing techniques e.g. Liquid Crystal Display (LCD). The main advantages are low power consumption and a thin display structure. This report contains an explanation of the emissive OLED technology, its functionality and the Physics of the organic layer structure in an OLED. The technology is described with respect to the two classes of organic materials used in displays, small molecules and conjugated polymers.

The aim of this study was to investigate preschool teacher?s perceptions about the curriculum goal concerning simple chemical processes. The result was based on narratives received by a qualitative study and semi-structured interviews of six preschool teachers. The results of the study showed that preschool teachers perceive that they actually are working in a relatively small scale with simple chemical processes and they do not really know what simple chemical processes are, and do not feel very familiar with the subject. Water, dough, mud, paint and baking were the most common activities that were used when working towards the curricular goal. However, it was never explained to the children that it was simple chemical processes they were working with during the activities, neither was it discussed among colleagues because of the uncertainty about the concept.

Syftet var att studera elevernas uppfattningar inom Naturbruksprogrammets hästinriktning om sambandet mellan ryttarens kroppsfysik och ridningen. Följande frågor har ställts: ? Vilken betydelse ansåg eleverna att en god kroppsfysik hade för ridningen? ? Hur uppfattade eleverna olika pedagogiska metoders betydelse för ridningen? ? Hur uppfattade eleverna olika pedagogiska metoders betydelse för kroppsfysiken? ? Hade eleverna förstått att ridningen påverkades av deras fysiska hälsa? För att besvara frågeställningar har jag använt mig av en enkät. De elever som besvarade enkäten deltog i ett projekt, som genomfördes med hjälp av olika didaktiska metoder och övningar samt observationer. Projektets avsikt var att förbättra ryttarens kroppsfysik samt dess inverkan på hästen.

The purpose of this investigation is to find out how the children?s exercises affect their learning capabilities. With exercise, I mean all kinds of movements, like Physics, walks and games.The method I will use in this investigation is interviews, where I choose to interview both teachers and their pupils at a school which uses an exercise-program called röris. Röris is an exercise program which involves moving to music. I also choose to look at Bunkefloprojektet, were scientists has investigated how the power of concentration is affected by exercise.My conclusion from the interviews and the literature is that I can?t prove that the children?s exercises affect their learning capabilities.

This Master?s thesis aims to map and analyse publishing patterns at two academic departments at the University of Gothenburg - the department of Physics and the department of History. The investigation has been guided by a set of questions: Who chooses to publish their scientific outcomes? In which forums do they publish findings? In what kind of media are the results published? What type of findings get to be published? The departments' publication lists have been examined, covering the years 2004-2007. Furthermore, ten scientists have been asked to describe factors contributing to their individual publishing pattern.

Det huvudsakliga syftet med denna rapport är att genomföra och testa en implementationsteknik för ragdolls ämnade användas i spelsammanhang. Implementationen sker genom en kombination av en verletimplementering tillsammans med en fördefinierad bone-hierarki i meshen som skall användas. Verletimplementeringen programmerades som en grund till en enklare fysikmotor och parsningen och struktureringen av meshen sköttes parallellt utanför fysikmotorn. Rotationsmatriser för samtliga större kroppsdelar, såsom över- och underarmar, överkropp, huvud etc. beräknas sedan i fysikmotorn och används för att vrida mesh-kroppen rätt.

Long time-series of pressure measurements often have high quality because the early instrumentsare more or less the same as the modern ones. A time-series from Lund consisting of three dailymeasurements from 1780-1997 has been homogenised and is therefore suitable for analysingpossible influences of the enhanced greenhouse effect. According to a two-layer model of theatmosphere one finds a shift in the frequency of baroclinic instability due to an increasedtemperature gradient caused by the increasing CO2. Baroclinic instability over the Atlantic Oceanis the main cause for frontal zone production, causing cyclonic activity over the southern part ofScandinavia. Changes to the baroclinic instability would therefore be traceable in the time seriesfrom Lund.

This study is focusing on students at compulsory level and their performance in national exam tests when the students first language is taken into account. Students in Swedish schools with non-Swedish speaking parents commonly follow language classes for limited Swedish proficient students. How does this affect their results when tested in other subjects as Physics,biology and chemistry? A general claim is that national tests can provide data for balancedand fair grades. This view is challenged in this paper, through Principal Component Analysisof test results that shows a difference between schools when the schools social position and share of limited Swedish proficient students are measured.

This essay is about the origin, planning and establishment of the European Space Research Organisation's (ESRO) sounding rocket base Esrange outside Kiruna in Northern Sweden. Three main questions are examined. First I show there were not just scientific and technical but also political, economical as well as military reasons to build a European rocket base. Second, I scrutinize the reasons to choose Northern Sweden as the location for the rocket base. As it turns out, the main reasons were the favourable location of Northern Sweden within the aurora oval zone, the proximity of the Kiruna Geophysical Observatory, and the possibility to use a large, although not quite uninhabited, area where the launched rockets could crash.

I den senaste PISA undersökningen från 2012 testades elevernas kunskaper i matematik, läsning och naturvetenskap hos femtonåringar runt om i landet. Sverige var det land som försämrat sina resultat mest av alla deltagande länder inom samtliga områden. Detta tyder på att något måste göras. Vi har studerat hur man kan väcka intresse för ämnena fysik och kemi inom naturvetenskapen. Detta för att öka de naturvetenskapliga kunskaperna hos eleverna i skolan.
