Sedan 1990-talet har uttrycket ”det svenska musikundret” använts för att beskriva Sverige som en stor musikexportör i världen. Detta begrepp är dock mångfacetterat och inte helt oproblematiskt. I denna uppsats har jag genom en kritisk diskursanalys studerat hur det svenska musikundret framställs inom kulturjournalistiken. Mitt syfte har varit att ta reda på vilka diskurser av det svenska musikundret som dominerar i medieframställningen, hur dikotomin kultur och ekonomi synliggörs i framställningen av dessa diskurser samt vilken roll journalisten har i reproducerandet. Uppsatsen har Bourdieus teorier om kapital och fält som grund, vilka är essentiella för förstå de regler som förekommer inom populärmusikens produktionsfält. Vidare har jag utgått från kritisk teori, forskning kring kulturjournalistik samt relationen mellan ekonomi och kultur. I min analys har jag kommit fram till fyra dominerande diskurser – den postmoderna, den marknadsliberala, den kollektivistiska och den anti- nationalistiska diskursen. Utifrån dessa diskurser har jag kommit fram till några olika sätt som dikotomin kultur och ekonomi synliggörs på. Det har skett en de-differentiering och placeringen på produktionsfältet kan idag tillåtas vara närmare den kommersiella polen. Musikundret är en del av ”varumärket Sverige”, där Sverige som musikland lyfts fram, och fungerar som en populärmusikalisk kanon eftersom uttrycket pekar på någon slag enhet. Journalisterna är representanter i ett åsiktsmaskineri som handlar om det svenska musik- undret, vilka till stor del består av vita män. De bidrar till formandet och reproducerandet av synen på det svenska musikundret som baseras på subjektiva åsikter. Synen på populärmusik verkar från journalisthåll ha förändrats mot en större öppenhet även för mer kommersiella akter inom musikundret. Det visar på att journalisternas texter präglas av den samhälleliga kontexten, samtidigt som deras texter är med och formar samhällskontexten.

The measurement of Cobb angles from radiographs is routine practice in spinal clinics. The technique relies on the use and availability of specialist equipment such as a goniometer, cobbometer or protractor. The aim of this study was to validate the use of i-Phone (Apple Inc) combined with Tilt Meter Pro software as compared to a protractor in the measurement of Cobb angles. Between November 2008 and December 2008 20 patients were selected at random from the Paediatric Spine Research Groups Database. A power calculation was performed which indicated if n=240 measurements the study had a 96% chance of detecting a 5 degree difference between groups. All patients had idiopathic scoliosis with a range of curve types and severities. The study found the i-Phone combined with Tilt Meter Pro software offers a faster alternative to the traditional method of Cobb angle measurement. The use of i-Phone offers a more convenient way of measuring Cobb angles in the outpatient setting. The intra-observer repeatability of the iPhone is equivalent to the protractor in the measurement of Cobb angles.

CFO and I/Q mismatch could cause significant performance degradation to OFDM systems. Their estimation and compensation are generally difficult as they are entangled in the received signal. In this paper, we propose some low-complexity estimation and compensation schemes in the receiver, which are robust to various CFO and I/Q mismatch values although the performance is slightly degraded for very small CFO. These schemes consist of three steps: forming a cosine estimator free of I/Q mismatch interference, estimating I/Q mismatch using the estimated cosine value, and forming a sine estimator using samples after I/Q mismatch compensation. These estimators are based on the perception that an estimate of cosine serves much better as the basis for I/Q mismatch estimation than the estimate of CFO derived from the cosine function. Simulation results show that the proposed schemes can improve system performance significantly, and they are robust to CFO and I/Q mismatch.

There is much still to learn about how young children’s membership with peers shapes their constructions of moral and social obligations within everyday activities in the school playground. This paper investigates how a small group of girls, aged four to six years, account for their everyday social interactions in the playground. They were video-recorded as they participated in a pretend game of school. Several days later, a video-recorded excerpt of the interaction was shown to them and invited to comment on what was happening in the video. This conversation was audio-recorded. Drawing on a conversation analysis approach, this chapter shows that, despite their discontent and complaining about playing the game of school, the girls’ actions showed their continued orientation to the particular codes of the game, of ‘no going away’ and ‘no telling’. By making relevant these codes, jointly constructed by the girls during the interview, they managed each other’s continued participation within two arenas of action: the pretend, as a player in a pretend game of school; and the real, as a classroom member of a peer group. Through inferences to explicit and implicit codes of conduct, moral obligations were invoked as the girls attempted to socially exclude or build alliances with others, and enforce their own social position. As well, a shared history that the girls re-constructed has moral implications for present and future relationships. The girls oriented to the history as an interactional resource for accounting for their actions in the pretend game. This paper uncovers how children both participate in, and shape, their everyday social worlds through talk and interaction and the consequences a taken-for-granted activity such as playing school has for their moral and social positions in the peer group.

This paper aims to develop the methodology and strategy for concurrent finite element modeling of civil infrastructures at the different scale levels for the purposes of analyses of structural deteriorating. The modeling strategy and method were investigated to develop the concurrent multi-scale model of structural behavior (CMSM-of-SB) in which the global structural behavior and nonlinear damage features of local details in a large complicated structure could be concurrently analyzed in order to meet the needs of structural-state evaluation as well as structural deteriorating. In the proposed method, the “large-scale” modeling is adopted for the global structure with linear responses between stress and strain and the “small-scale” modeling is available for nonlinear damage analyses of the local welded details. A longitudinal truss in steel bridge decks was selected as a case to study how a CMSM-of-SB was developed. The reduced-scale specimen of the longitudinal truss was studied in the laboratory to measure its dynamic and static behavior in global truss and local welded details, while the multi-scale models using constraint equations and substructuring were developed for numerical simulation. The comparison of dynamic and static response between the calculated results by different models indicated that the proposed multi-scale model was found to be the most efficient and accurate. The verification of the model with results from the tested truss under the specific loading showed that, responses at the material scale in the vicinity of local details as well as structural global behaviors could be obtained and fit well with the measured results. The proposed concurrent multi-scale modeling strategy and implementation procedures were applied to Runyang cable-stayed bridge (RYCB) and the CMSM-of-SB of the bridge deck system was accordingly constructed as a practical application.
