Ny princip för spänningsreglering i Fortum Distributions mellanspänningsnät i Stockholm.
The voltage regulation in Fortum Distributions medium voltage network in Stockholm does not work satisfactory. This results in too high distribution voltages with many customer complaints as a consequence. The reason is the model responsible for compensating for voltage drops in the distribution network. Despite several adjustments Fortum has not been able to find the source of the high voltages and has therefore appointed an investigation in the form of a thesis work.The aim of this investigation is to locate the error and to produce a proposal regarding the solution of this error using the existing system, common industrial knowledge, state of the art research and the option to use voltage readings from the different substations.The conclusion of this master thesis is that the largest contribution to the high voltage levels is made by the large compensation for distribution loses. Furthermore an additional error in the model has been found.
Relationen mellan prestationer och ersättning
The thesis handles the principal-agency problem between shareholders and the Chief Executive Officer.

Data was collected from corporate annual reports between the years 2000 ? 2008 and the study covers 39 Swedish companies from the Stockholm Stock Exchange Large Cap list. To examine whether there is a link between the CEO´s compensation and firm performance, we performed a regression analysis, and no significant relation is found.
Vad vet gymnasieelever om betygskriterierna och kursplanen i Idrott och Hälsa?
The Scanian woodfences has been determined by two mainly elements: Scania's composition of tree species, with a large element of deciduous forest, and the local building tradition which has more in common with the European continent than the Swedish tradition. By examining responses from ethnological question lists deriving from the first half of the 1900s, combined with literature studies, I have been able to deepen and broaden the knowledge behind the various fencing design. In addition I ?ve constructed maps which could illustrate their historical geographic distribution.I have come to the conclusion that there was three main types of woodfences that was most common until the barbed wire was introduced in the early 1900s and later on replaced the elderly woodfences. Common for the three main types is that the base material was made out of Juniperus communis, this largely because of its durability against rot.
Likvärdig utbildning för alla barn? En studie om boendesegregation och diskriminering i Sveriges grundskolesystem
The major focus in this study is structural inequalities in primary school in Sweden. UNESCO points out that in many developing countries, up to 40% of the children perform at or below the lowest proficiency level in language and mathematics. Sweden has been criticized by the UN about the large differences in educational achievements between different regions. Based on an official study Sweden considers that those differences are related to ethnically segregate residential areas. My research question is whether the Swedish government takes adequate consideration of the impact that socioeconomically aspects have on educational achievement.

Att skapa kunskap i informationshavet - Om hur text kan struktureras för att skapa lärande i intranät
Creating instructions is not just about words, but also about text structure. A
company creates many instructions to document their management systems, which
often are presented through an intranet. This study examines how the text can
be presented to make content understandable and give employees the knowledge to
take action. An interview survey was made at Skanska Sweden and their
management system "Vårt sätt att arbeta". The results show that it is mainly
about creating an overview of the system and creating separations between
different text sections.

Ordförståelse i förskolan : Pedagogers syn på arbetet med yngre barns utveckling av ordförståelse i en stor barngrupp med blandad språkbakgrund
Syftet med studien är att synliggöra förskollärares syn på arbetet med ordförståelse för yngre barn i större barngrupper där barnen har blandad språkbakgrund. Frågeställningarna är hur förskollärarna arbetar med att introducera nya ord, vad de tror påverkar inlärningen och hur utvecklingen av språket påverkas av faktorerna kring barngruppen. Kvalitativa intervjuer har genomförts med två förskollärare som arbetar med barn i åldrarna tre till fem år på förskolor i större städer i Mellansverige. Studien visar att organisation och planering är en viktig del i arbetet i en stor barngrupp. Pedagogens förhållningssätt och goda förebilder hos både pedagoger och andra barn är en viktig del i hur barnen lär sig nya ord.
Integritetsskyddet vid forskning : - En analys av det rättsliga stödet för att lämna ut och behandla känsliga personuppgifter vid registerforskning
The study explores collective action in Sweden between 1980 to 1995 using time-series data from the European Protest and Coercion Database. In spite of severe hardship during the crisis of the early 1990s, Swedish strike-rates declined. However, contention merely shifted from workplaces into the streets; there was indeed a protest movement against austerity, as shown by a series of large demonstrations, and some riots, between 1989 and 1993. Further analysis indicates this movement faded as it was increasingly chanelled into the electoral campaign of the labor pary; having won the 1994 election, the organised labor movement no longer had an interest in sustaining the protest movement against austerity..
Hur påverkas högstadielevers studier av klass och kön? : Skolprestation, studieval och attityder till skolan i en kommun belägen i Norrlands inland
How do gender and socioeconomic backgrounds affect students? academic performance, educational choices and attitudes towards education? Moreover, does class play the same role for girls and boys? In order to find this out, I surveyed students in a small province located in the northern inlands of Sweden. The survey was answered by nearly every student in the ninth grade of that year, a total of 160 people. The results revealed that girls in this area have less faith in their capabilities than boys, despite getting much better grades. Many more girls than boys want to go onto college or university studies.
Att dela med sig av sin vardag : En studie om fotoapplikationen Instagram
Photography has long been of importance for humans in aspects of community, sharing and documenting. It has previously only existed in analogue format and with larger cameras. We have presently reached a new generation of cameras and photography. The new smaller compact cameras that are provided with most cellular phones take digital images of varying quality and accounts for a large part of photography. With the emergence of social media, photography and social interaction combined came photo applications with different features.
Klassning av renbete med hjälp av ståndortsboniteringens vegetationstypsindelning :
During thousands of years, reindeer have adapted to living under harsh conditions with large seasonal variations in climate and forage availability. This adaptation implies that body functions and nourishment needs are strongly bound to the season. In the summer the reindeer has to maximize food intake to build up fat and protein reserves for the winter. More than 200 different plant species are included in the reindeer diet, but since reindeer have an unique ability to use the nourishment in lichen, different lichen species make up a large portion of their winter diet in many areas. Fundamental for reindeer husbandry is access to natural grazing during most of the year.
Leder kritisk publicitet till kritisk publicitet?
Academic research indicates that critical publicity can have a detrimental effect on brand attitudes. The negative effects have been showed to be buffered by cognitive bias elicited by strong favourable attitudes, commitment, brand certainty and brand identification. It has been proposed that the influence of such bias in a news reporting context should be studied, something that also is interesting from a brand perspective. The study therefore investigated whether a well-publicised scandal in one period can lead to increased critical publicity in the coming periods. A case study of Swedish grocery chain ICA was conducted.

Journalistik i ett nytt medium : En studie av hur journaliststudenter på två universitet i Sverige använder Twitter
The aim of this study was to find out how journalism students at two universities in Sweden, Gothenburg University and Linnaeus University in Kalmar, use the social networking service Twitter. We were primarily interested in whether the students are using Twitter as a journalistic tool, which includes gathering, production and distribution of material. The study focused on journalism students because they soon will enter the working life and therefore can provide an indication of whether Twitter is a part of the future of journalism. We have used theories of mass communication to describe the development in the area and explore how journalism has adapted to this change. The study was conducted in the form of a survey in which the students answered questions about how they use Twitter and what they think about the social networking service.
