Sista generationens renskötare?
The purpose of this paper is to present a possible understanding of why the company Tekola is segregated according to sex. In accordance to this purpose, an understanding of how the segregation affects the employees in relation to power, values and possibilities is discussed. The theoretical understanding is that the organization of men and women within Tekola is done in close connection to creation of the meaning of gender in Tekola. This, in turn, affects and is affected by the recruitment to and within the company. Through the study of statistics from a survey, five interviews with employees and former employees and Tekolas? equality plan, we are able to see the possible existence of a glass ceiling, and a culture of homosociality, which affects the possibilities of women to enter the company and also to gain full entrance to power-positions in a negative way.

Neurodidaktik och matematik : En litteraturstudie om neurodidaktikens betydelse för matematikundervisningen
Ämnet neurodidaktik bygger på hjärnforskning och etablerade teorier inom det pedagogiska området. Syftet med vår studie är att dra slutsatser av de rön vi finner inom hjärnforskningen som studerar hur hjärnan fungerar i inlärningssammanhang. Vi har lyft fram ett antal förutsättningar för lärande i vår studie som alla får stöd i aktuell hjärnforskning. Dessa förutsättningar har vi kopplat samman med hur hjärnan utvecklas ur ett matematiskt perspektiv. Litteratursökningen har ägt rum i faktaböcker och databaser och för att få vägledning har vi kontaktat experter inom området.
Långsiktigt spårväxelunderhåll - Förutsättningar och möjligheter
Due to their complexity and heavy wear from rail traffic, switches are a sensitive part of the railway infrastructure and moreover expensive to maintain. Furthermore, increasing railway traffic not only accelerates the wear rate but also obstructs the necessary maintenance measures. This paper examines the opportunities for a transition to a long-term maintenance strategy in the Swedish railway network. It contains a study of the maintenance strategy of Banverket, and also analyses statistics of errors in the railway infrastructure. The survey was completed utilising interviews with infrastructure managers, maintenance contractors, planners of railway operations and the Banverket material service department.
Matematiska kompetenser i läroböckernasuppgifter : En granskning av två Matematik A läroböcker
Syftet med denna studie är att undersöka förekomsten av de matematiska kompetenserna i läroböcker för Matematik A. Centralt i studien är de sex matematiska kompetenser, som Palm et al. (2004) analyserat fram ur de nationella styrdokumenten. Dessa kompetenser är: kommunikationskompetens, modelleringskompetens, resonemangskompetens, begreppskompetens, problemlösningskompetens och algoritmkompetens. För att nå syftet genomfördes en analys av uppgifter i två läroböcker för Matematik A.Undersökningens resultat visar att alla sex matematiska kompetenser finns representerade i läroböckernas uppgifter.
Klassrumsaktiviteter för att utveckla och befästa elevers taluppfattning under grundskolans år 1-3
Studien syftar till att få grundläggande kunskaper om hur barn lär med alla sinnen och vilka faktorer litteraturen pekar på för att utveckla och befästa elevernas taluppfattning. Den teoretiska delen behandlar två områden; inlärningsstilar där fyra grundtyper beskrivs och en litteraturstudie där det framkommer vilka begrepp som är viktiga för att få den förförståelse som krävs längre upp i årskurserna.I resultatdelen finns 10 olika lektionsförslag som utvecklar och befäster barns kunskaper om taluppfattning. Övningarna har jag provat i olika barngrupper för att kunna ta till mig de oförutsedda saker som kunde hända under lektionen. Till varje lektionsförslag finns anvisningar vad respektive övning tränar och vilka lärstilar den vänder sig till.Det är mångfalden som leder fram till att eleverna erhåller en stabil taluppfattning..
Population genetic analysis and breed assignment of three Swedish horse breeds
The genetic relationship between three Swedish horse breeds was investigated using microsatellite data from 144 loci in 30 horses. The North Swedish Trotter is believed to have been crossed with the Standardbred in the 1950?s to produce a faster trotter. If true, the North Swedish Trotter should be more alike the Standardbred than what the North Swedish Draught Horse is, from which they originate. This was investigated using F-statistics and Nei?s distance in GENEPOP and GENETIX and cluster assignment in STRUCTURE.
Integrering av ett främmande språk i matematikundervisningen
Content and Language Integrated Learning (CLIL) is a relatively new method for learning a foreign language. CLIL programs are growing in popularity and more and more schools are adopting it all around the world. There is still no special education for the teachers working with CLIL, though research suggests it may be an effective method for achieving good results.To get a realistic view of the work of a CLIL teacher, I have interviewed four different mathematic teachers who work at CLIL international schools in Spain with English as the foreign language. I have compared their methods and experiences with the main ideas of current research in this particular field.The survey shows that the teachers? views about how CLIL is to be used do not completely correspond to that of the research.
Dimensionering av industrilager för biobränsle :
The aim of this study was to develop a simple model for calculating stock costs for bio fuel at Billerud Karlsborg and subsequently recommending a suitable stock level of bio fuel. The stock components considered in the model are GROT (branches and tops), bark, dry wood chips, raw wood chips from barking and sawdust. The calculations are based on a probability distribution of historical deviations between ordered and delivered volumes. The model presents two different ways to manage the supply in case of irregular deliveries. The first way is to stock enough volume to cover the deviations and the second way is to compensate with a quick purchase from the spot market (at extra high purchase prices).
Aspektorienterade vittringsprocesser : En studie i ett nordiskt klimat
Weathering on rocks is an important component of the world?s geomorphology. One way to measure weathering on rocks is to analyse rock hardness. This is a study conducted in the northern hemisphere on granite rocks in Uppsala, Sweden. A Schmidt hammer is used to create a correlation analysis between the aspects on three glacial erratic boulders and rock weathering.
Svenska Akademiens Nobelbibliotek : en uppsats om Nobelbibliotekets inköpspolicy och förändringar inom inköpta språkområden sedan 1904
The essay is about the Nobel Library's investments in fiction, the change of certain linguisticareas since 1904 and the purchase policy of the Library. The paper contains an introductoryhistorical chapter, where I describe the history of the Swedish Academy, the life and willof Alfred Nobel and in conclusion a description of the Nobel library of the Swedish Academy.When writing this essay I have used a combined qualitative and quantitative method, meaningthat I have interviewed the librarians of the Nobel Library, studied the purchase catalogues,and kept statistics over the books.in different linguistic areas purchased since 1904 onwardwith an emphasize on years ending with "4". The outcome of this survey is that the purchaseof books within the different speech areas doesn't vary as much as first expected, and thatthere rises and falls within all the linguistic areas which could be further explored..
Beräkning av koldioxidutsläppet från bostadssektorn i Stockholms län
During the last decades the housing sector has increased continuously, and housings and services accounted for 40 % of the energy usage in Sweden during 2011. The expansion in number of buildings in society has resulted in an increase in both energy usage and emissions of greenhouse gases. It is crucial to enable a sustainable development of society and as a result, the demand to reduce the emissions of carbon dioxide is a current question. In this study, the carbon dioxide emitted from the housing sector in Stockholm is estimated. The housing sector can be divided into different types of houses such as apartment blocks, single-family houses and holiday houses. By collecting information of the energy purchased in respective households, a computational model is generated that calculates the total emission of carbon dioxide.
Läraren som ledare och hennes roll i elevers kunskapsutveckling och socialt uppförande
Over the past ten years, the pupils' performance and grades has fallen and the number of competent to high school has decreased gradually. The Swedish school has been criticized and the role of the teachers has been questioned, among other by the media. In autumn 2007 Johannesskolan, one of Sweden's tenth worst schools replaced the ordinary teachers of Class 9A against eight of the country's "main" educators with the goal of the class to become one of Sweden's third major. The teachers have the autumn term in which to achieve the goal and the outcome will be measured by national tests in core subjects Swedish, English and Mathematics. The aim of this paper is to examine the role of the teacher's leadership in relation to the pupils' social and intellectual development, and identify common leadership of these eight educators.
Är dagens studenter morgondagens företagare? : En studie om studenters attityd till företagande
In this paper I study how the repeal of the Swedish wealth tax (1 of January 2007) has affected people´s labour supply behaviour. This particular issue is relevant because it may help us understand some of the effects of the earnings tax changes that have taken place in Sweden. Accoring to standard economic theory a repealed wealth tax is similar to an income effect for the persons who previously paid the tax. That means that they theoretically will want to consume more leisure, that is decrease their labour supply. The method I am using to test this hypothesis is a difference-in-difference approach where the treatment group consists of persons who previously paid the tax and the control group of comparable persons who did not pay the tax.
