Vem får vara synlig i läseboken? : Om etnicitet i läsläror för elever i årskurs ett

Having different kinds of literature is an important part of the education in school and schoolbooks, in shape of reading-books, are common in the first year of primary school. The texts pupils encounter in school are important for how they form their identity and thoughts about what is right or wrong and what is natural or unnatural. People of other ethnicity than Swedish, or with another skin colour than white, have often in the past been portrayed negatively in reading-books as if they are of less worth. According to the Curriculum for the Compulsory School System (Lpo94) the school shall act for understanding of all people and every person?s equal value.The study analyses how ethnicity is portrayed in reading-books for pupils in the first year of primary school.

Renovering av flerfamiljsbostäder inom miljonprogrammet ur ett energi- och lönsamhetsperspektiv

Miljonprogram is a Swedish building program from 1964 to 1975. During that time about a million homes were constructed. Now, almost 50 years later, they are in desperate need of renovation. In order to fulfil the Swedish environmental objective to decrease energy consumption 50 per cent until 2050, considerable housing stock built under the Miljonprogram has to be renovated.Focus in this thesis is on the building services and theirs profitability that can decrease energy consumption in households build during the Miljonprogram. Building construction is not considered in this report.

Simulering av ventilationsbehov: vid framtida produktionsökning i Renströmsgruvan

Ventilation används i underjordsgruvor för att tillföra syre, späda och transportera ut föroreningar samt kontrollera arbetsklimatet. De föroreningar som förekommer är främst avgaser från dieseldrivna maskiner och skjutgaser. Den luftmängd som krävs för att kontrollera dessa föroreningar beror därmed på antalet och storlek på maskiner respektive sprängningar. Boliden AB har för avsikt att höja årsproduktionen i Renströmsgruvan till 400 kton från dagens 300 kton. En undersökning krävs därför för att bestämma om dagens huvudfläktar är tillräckliga samt eventuell utbyggnad av infrastrukturen.

Ombyggnad av ventilation i kulturbyggnader

I detta arbete studeras hur en systemombyggnad i kulturbyggnader kan gå till med avseende påinstallationerna. I Sverige finns det idag totalt ca 4,7 miljoner byggnader av vilka ca 235 000-280 000bör genomgå kulturbevarande byggnadsvårdsinsatser. Vid ombyggnad av ventilationen i enkulturbyggnad är det viktigt att man, samtidigt som man får en ändamålsenlig och energisnål lösning,tar hänsyn till byggnadens karaktär och förutsättningar så att den kulturhistoriskt värdefulla miljönbevaras.I detta arbete studeras tre olika kulturhistoriskt värdefulla byggnader som genomgått renovering avventilationssystemet under de senaste tio åren. Byggnaderna är Skridskopaviljongen, Dekanhusetoch Södra Bancohuset, som alla förvaltas av Statens fastighetsverk (SFV). Efter samtal, studier ochundersökningar om de tre byggnaderna visar det sig att det är viktigt att i början av ensystemombyggnad i en kulturbyggnad, först läsa in sig på byggnaden samt ställa sig frågorna: vad skabyggnaden användas till, vilken verksamhet passar här, vilket systemval kommer att passa brukarenbäst mm.

Simulering av inneklimat : Vid fönsterbyte

SammanfattningI detta arbete simuleras några utvalda kontorsrum för att undersöka hur det termiska klimatet påverkas då äldre fönster med vanlig isolerruta byts ut mot moderna med energibesparande och solavskärmande glas. Dessutom görs simuleringar med yttre solavskärmning för att se hur de kan minska innetemperaturerna under sommaren. Därutöver undersöks hur den befintliga ventilationen kan förbättra det termiska klimatet. Slutligen undersöks vilken besparingspotential som kan förväntas av glasen.För arbetet simulerades först hur det termiska klimatet för grundfallet under sommar och vinter, sedan några olika glasrutor och yttre solavskärmning. Därefter simulerades olika åtgärder som, minskad belysning och förändringar av befintlig ventilation.Simuleringarna visade inte några problem med det termiska klimatet vintertid, dock höga temperaturer under sommaren.

Språk och identitet : en intervjustudie av några gymnasieungdomar med svenska som andraspråk

This study aims to investigate, describe and discuss the views of a group of adolescents on their identity and the process of second language acquisition. They all came to Sweden and started studying in Swedish schools in the last three years without any knowledge of the Swedish language.The study has been conducted with respect to the adolescents own perspectives and what they consider important.The methods used are group discussions/ interviews, observations in class and informal discussions with teachers and adolescents.Their voices are described and discussed in this paper. One must take into consideration that there is no objective of being neutral or to generalize the results to any other group or category. On the contrary the study has involved critical self- scrutiny and active reflexivity according to ethnographic tradition.Symbolic interaction has provided a theoretical framework for the study. Looking into how social identities may be constructed or communicated from the adolescents voices and looking in to their use of language the study reveals that several expectations and situations need? to be met by different identities.

Downward migration and transfer to plants of radiocaesium in Scottish soil profiles : a comparison with earlier studies

Following the accident at the nuclear power plant in Chernobyl in 1986, great volumes of137Cs were distributed over large parts of the former Soviet Union and Europe. Over Scotland,radiocaesium was deposited as wet deposition. Due to the relatively long physical half-life of30 years, there are still measurable activity concentrations in the natural environment. Thisstudy was made on two organic soils, Knockandy Hill and Rora Moss, situated in the easternpart of the central highlands of Scotland. At these two sites, studies on migration and transferbetween soil and plants were conducted.

Several design companies fancy growth and to receive a wider market share to expand on the international market. One of them is Design Communicaton who has made a couple of acquisitions, to receive wider comptences and to cover different segments. That has lead to an increased brand portfolio with different subbrands, which can be complicated to handle efficiently in the internal and external communication.

Inkludering kontra utanförskap inom Idrott & hälsa :  En kvalitativ studie gällande hur elever med funktionsnedsättning upplever ämnet

The subject-matter of the following essay is to investigate the relationship between what is commonly called Deep Ecology or Biocentric Philosophy, as articulated by the co-founder of the Deep Ecology Movement, Arne Naess, and later proponents of the biocentric school of environmentalist thought. I contrast Naess? concept of Self-realization as founded in his Ecosophy T to the ideas of american conservationist and co-founder of the radical green movement Earth First! Dave Foreman, and to the controversial finnish environmentalist and ecofascist Pentti Linkola?s ideological agenda of population-reduction respectively.According to some critics of the movement, especially the social ecologist Murray Bookchin and French liberal philosopher Luc Ferry, the Deep Ecology ideology is essentially misanthropic and totalitarian in structure. A central idea among deep ecologists is that ecosystems and natural entities have intrinsic value in themselves, even outside a human social context. This idea is thought of among deep ecologists to create a philosophically sound basis for counteracting the environmental global crisis.

Acehkonflikten - en analys med identiteten i fokus

A violent conflict emerged in the Indonesian province of Aceh in 1976, with the rebels of the Free Aceh Movement, GAM, on one side, and the Indonesian government on the other. GAM demanded Aceh to become independent, but the Indonesian government did not accept their nationalistic claims. The conflict therefore lasted for almost thirty years, and many civilians were killed during this period. This essay deals with this particular conflict; its causes and its solution. In the centre of the analysis we find theidentity of the Acehnese people, and the way in which this identity has beenconstructed and re-constructed throughout the history.

Det kan vara farligt att ligga lågt - om stadsplanering inför stigande vattennivåer : Exempel från Göteborg, Kristianstad och Arvika

In this study is being examined how cities can be planned in the face of rising water levels and extreme weather, due to the changing climate. The starting point has been to investigate how the problems can be tackled and how the positive sides of water in the city can be strengthened, and synergy effects and greater sustainability be achieved thereby. The method has been literature studies and case studies containing interviews and visits. Göteborg, Kristianstad and Arvika have been studied for discussions and ideas about adaptation. Today, building near water is very popular which brings both advantages and disadvantages.
