The art of choosing the right tram – A study of urban segregation, choice of school and young people’s life plans When discussing barriers to integration and young people’s choice of school, research often focuses on language skills, cultural capital, supportive environments and other more obvious, distinct and material aspects that have an impact on educational achievement. In the present study, we have instead chosen to look at how young immigrants construct their inner career landscapes and life-plans, and how this relates to their perception of ethnicity, neighbourhood and identity. The sample used here consists of altogether twenty individuals. The interviews were used to explore certain designated dimensions and processes. All interviews were conducted in the school environment, in classrooms and other locations. The students attended two different inner-city schools. A narrative-sociological approach is used in the analysis. The young people’s perceptions and narratives are analysed in relation to concepts such as: territorial stigmatization, identity, self-perception and modifications of life plans. The findings show that the feelings of otherness which originates in housing conditions, experiences of exclusion and the everyday life of many immigrants, are transposed into the school area and transformed into strategies and life plans.

Allvac 718 Plus and Haynes 282 are relatively new precipitation hardening nickel based superalloys with good high temperature mechanical properties. In addition, the weldability of these superalloys enhances easy fabrication. The combination of high temperature capabilities and superior weldability is unmatched by other precipitation hardening superalloys and linked to the amount of the γ’ hardening precipitates in the materials. Hence, it is these properties that make Allvac 718 Plus and Haynes 282 desirable in the manufacture of hot sections of aero engine components. Studies show that cast products are less weldable than wrought products. Segregation of elements in the cast results in inhomogeneous composition which consequently diminishes weldability. Segregation during solidification of the cast products results in dendritic microstructure with the segregating elements occupying interdendritic regions. These segregating elements are trapped in secondary phases present alongside γ matrix. Studies show that in Allvac 718Plus, the segregating phase is Laves while in Haynes 282 the segregating phase is not yet fully determined. Thus, the present study investigated the effects of homogenization heat treatments in eliminating segregation in cast Allvac 718 Plus and Haynes 282. Paramount to the study was the effect of different homogenization temperatures and dwell time in the removal of the segregating phases. Experimental methods used to both qualify and quantify the segregating phases included SEM, EDX analysis, manual point count and macro Vickers hardness tests. Main results show that there is a reduction in the segregating phases in both materials as homogenization proceeds hence a disappearance of the dendritic structure. In Allvac 718 Plus, plate like structures is observed to be closely associated with the Laves phase at low temperatures and dwell times. In addition, Nb is found to be segregating in the interdendritic areas. The expected trend of increase in Laves as a result of the dissolution of the plate like structures at the initial stage of homogenization is only detectable for few cases. In Haynes 282, white and grey phases are clearly distinguished and Mo is observed to be segregating in interdendritic areas.

Syftet med uppsatsen är att undersöka möjliga påverkansfaktorer till varför en mindre friskola ärunderrepresenterad av elever med utländsk bakgrund. För att uppnå syftet ställs tvåfrågeställningar; (1) Vilka förklaringar ger elever med utländsk bakgrund som inte studerar påskolan till varför de inte valt att studera vid skolan? (2) Vilka förklaringar ger elever med utländskbakgrund som studerar på skolan till varför de har valt att studera vid skolan?För att svara på dessa frågor genomförs dels en litteraturstudie, dels en mindre kvantitativenkätundersökning samt en mindre kvalitativ intervjuundersökning. I litteraturstudien går jagigenom olika påverkansfaktorer till den idag påfallande ökande etniska skolsegregationen samtden teori som ligger till grund för analysen av mina två mindre studier.Resultatet visar att det inte finns något entydigt sätt att förklara friskolans brisande mångkultur.Utifrån litteraturstudien samt uppsatsens två mindre studier konstaterar jag att det åtminstonefinns tre påverkansfaktorer till skolans bristande mångkultur. (I) Staden har en påfallande etniskboendesegregation, som påverkar skolornas elevsammansättning, (II) Kompisrelationer är viktigaför skolungdomar vid deras skolval och (III) Skolans information är bristfällig, både om självaskolvalet och om skolans arbetssätt. Resultatanalysen visar också fler faktorer som i mindre gradän de tre nämnda sannolikt påverkar friskolans elevsammansättning.

The Norrliden project. Genderisation and ethnification of a low status residential area in the local press Media often contributes to segregation by constructing low status residential areas as “different” from what is “normal” and “Swedish”. Research into media representations of these residential areas often focuses big city contexts. Furthermore, research tends to be preoccupied with the construction of ethnic differences, paying little attention to the relationship between construction processes of gender and ethnicity. This article is a critical analysis of how the local daily newspapers in a medium sized town, Kalmar, construct stereotypes of immigrants and gendered identities in the low status residential area Norrliden. Two newspapers were studied in search for articles related to the area, published during the year 2005. Despite the newspapers’ claim that they want to contribute to a more nuanced and less stereotyped image of the residential area the consequences of their work seem to be the opposite. The representation sof the area are coded with stereotypes suggesting that the area is unsafe and dangerous and that the people who live there are motivated by affect and emotions rather than by successful socialisation. These representations are also characterised by notions of ethnicity and gender, as well as class. Norrliden is described as an area in need of change and improvement, as an unfinished project dependent upon aid from the outside. A reading of the 2005 media representations of Norrliden exposes an example of “symbolic violence” in that texts and photographs repeatedly degrade the area and its inhabitants.
