- IceCube is a km-scale neutrino observatory under construction at the South Pole with sensors both in the deep ice (InIce) and on the surface (IceTop). The sensors, called Digital Optical Modules (DOMs). detect, digitize and timestamp the signals from optical Cherenkov-radiation photons. The DOM Main Board (MB) data acquisition subsystem is connected to the central DAQ in the IceCube Laboratory (ICL) by a single twisted copper wire-pair and transmits packetized data on demand. Time calibration is maintained throughout the array by regular transmission to the DOMs of precisely timed analog signals, synchronized to a central GPS-disciplined clock. The design goals and consequent features, functional capabilities, and initial performance of the DOM MB, and the operation of a combined array of DOMs as a system, are described here. Experience with the first InIce strings and the IceTop stations indicates that the system design and performance goals have been achieved. (c) 2009 Elsevier B.V. All rights reserved.

- Neutrophils are short-lived leukocytes that migrate to sites of infection as part of the acute immune response, where they phagocytose, degranulate, and form neutrophil extracellular traps (NETs). During NET formation, the nuclear lobules of neutrophils disappear and the chromatin expands and, accessorized with neutrophilic granule proteins, is expelled. NETs can be pathogenic in, for example, sepsis, cancer, and autoimmune and cardiovascular diseases. Therefore, the identification of inhibitors of NET formation is of great interest. Screening of a focused library of natural-product-inspired compounds by using a previously validated phenotypic NET assay identified a group of tetrahydroisoquinolines as new NET formation inhibitors. This compound class opens up new avenues for the study of cellular death through NET formation (NETosis) at different stages, and might inspire new medicinal chemistry programs aimed at NET-dependent diseases.

Object shift in spoken Mainland Scandinavian
- 2013

Konferensbidrag (refereegranskat)abstract
- Object Shift (OS) has been studied extensively across the Scandinavian languages (Holmberg 1986, 1999, Vikner 2006). Traditionally, OS is assumed to apply to all weak pronominal objects in Danish, Norwegian and Swedish. However, based on written corpora, Andréasson (2008, 2009, 2010) shows that while OS is obligatory with weak pronominal objects in Danish, these elements may marginally remain in situ in Swedish (cf. also Josefsson 2010 for similar Swedish results based on grammaticality judgments). In an elicited production study, Anderssen et al. (2012) find that Norwegian speakers consistently shift such objects, (1). Moreover, Andréasson also shows that not all weak pronominal objects behave the same way. While pronouns with nominal referents typically undergo OS, weak pronoun det ‘it’ referring to a clause or VP may remain in situ in Swedish. In contrast, in Danish also this latter type usually shifts. Anderssen & Bentzen (2012) argue that det with non-individuated (clausal/VP/type DP) referents generally remains in situ in Norwegian, (2).In this study, we investigate OS in spontaneous speech of adults in large Danish, Norwegian and Swedish child language corpora (Plunkett 1985, 1986; Simonsen 1990, Anderssen 2006; and Plunkett & Strömqvist 1992, Strömqvist et al. 1993, respectively).Our corpus data display both similarities and differences with the patterns reported above. Concerning non-contrastive weak pronominal objects with a nominal referent, our data show a similar pattern to that of previous studies. In Danish and Norwegian, these objects occur in a shifted position 80-90%, while in Swedish the majority of such objects remain in situ (57%). With respect to det ‘it’ with a non-individuated referent, our spoken data are quite different from those reported in Andréasson. While she found that these elements relatively frequently undergo OS in Swedish, we see a strong tendency for non-individuated det to remain unshifted (found in shifted position less than 3% in both Swedish and Norwegian). Moreover, for Danish, Andréasson reports that non-individuated det practically never remains in situ, while in our Danish data, such elements remain in situ as much as 86% of the time.Despite these discrepancies, our investigation confirms the picture regarding OS that has emerged in recent years (Andréasson 2008, 2009, 2010, Mikkelsen 2010, Josefsson 2010, Anderssen & Bentzen 2012), namely that OS is not a uniform phenomenon. There is much variation both depending on type of pronoun (and its referent), and across the Mainland Scandinavian languages. To account for some of the variation, Andréasson links OS to accessibility and cognitive status of the pronominal object. Similarly, Anderssen & Bentzen argue that Norwegian OS is clause-internal topicalization of familiar topical objects with an individuated referent, while this position is generally unavailable to pronouns with a non- individuated referent. Since OS clearly depends on information structure, the discrepancies between our data and those of Andréasson may be due to the different types of corpora studied (spoken vs. written discourse).Against this backdrop, we investigate the various factors influencing the position of pronominal objects across spoken Danish, Norwegian and Swedish. Examples:(1) A: Så du husetNEUT? B: Ja, jeg likte detNEUT ikke. saw you house.the yes I liked it not ‘Did you see the house?’ ‘Yes, I didn’t like it.’(2) A: Spiste du noe frukt? B: Nei, jeg gjorde {*detVP} ikke {detVP}. ate you any fruit.MASC no I did it.NEUT not it.NEUT ‘Did you eat any fruit?’ ‘No, I didn’t.’ (det = ‘eat any fruit’)ReferencesAnderssen, Merete & Kristine Bentzen. 2012. ‘Norwegian Object Shift as IP-internal topicalization,’ Nordlyd 39.1: The Grammar of Objects, 1-23.Anderssen, Merete, Kristine Bentzen & Yulia Rodina. 2012. ‘Topicality and complexity in the acquisition of Norwegian Object Shift,’ Language Acquisition 19.1: 39-72.Anderssen, Merete. 2006.

Tidskriftsartikel (refereegranskat)abstract
- Recent work on Object Shift (OS) suggests that this is not as uniform an operation as traditionally assumed. In this paper, we examine OS in the spontaneous speech of adults in large Danish, Norwegian and Swedish child language corpora in order to explore variation with respect to OS across these three languages. We evaluate our results against three recent strands of accounts of OS, namely a prosodic/phonological account, an account in terms of cognitiv status, and an account in terms of information structure. Our investigation shows that there is both withing-language and across-language variation in the application of OS, and that the three accounts can explain some of our data. However, all accounts are faced with challenges, especially when explaining exceptional cases.

- This chapter considers the language biographies narrated by two female forced migrants from the area of the former Yugoslavia that is now Bosnia. We analyse these to access defining traumatic and agentic moments towards high-level language and literacy skills in Swedish. They arrived, along with many other forced migrants fleeing the Balkan wars, during a deep economic recession. The immigrant group has outperformed other forced migrant groups in Sweden and these language biographies provide pertinent insights into adaption, and the route to the achievement of high-level literacy and language competencies. These insights should be viewed broadly and not as prototypical for forced migrants. Our findings suggest agentic acts of proactive language- and literacy-learning need to be interwoven across an individual’s social, academic, and working life.

Bokkapitel (refereegranskat)abstract
- Artikeln behandlar ett återkommande språkligt mönster i idrottstränares instruktioner och återkoppling till tränande barn. Mönstret utgörs av ett tvåledat yttrande där ett instruerande led föregås av ett orienterande led med lägre informationsvärde och en delvis annan funktion. I artikeln beskrivs detta orienterande led som scene-setting, vilket syftar på att den orientering som föregår och förbereder instruktionen är nödvändig för att yttrandet i sin helhet ska fungera kommunikativt. Förekomsten av scene-setting i tränares instruktioner får konsekvenser för hur yttrandet struktureras språkligt, och i artikeln åskådliggörs detta genom analyser av två strukturer: dels en V3-struktur där en initial när-sats följs av en sats med rak ordföljd, dels en kontrasterande satsrelation som påverkar möjligheten att använda konjunktion. En central slutsats är att instruktionernas utformning är starkt påverkad av de speciella kommunikativa villkor som präglar en träningskontext som inkluderar barn.

Direct observation of a ferri-to-ferromagnetic transition in a fluoride-bridged 3d-4f molecular cluster
- 2012
-
Ingår i: Chemical Science. - : Royal Society of Chemistry (RSC). - 2041-6520. ; 3:4, s. 1024-1032

Tidskriftsartikel (refereegranskat)abstract
- We report on the synthesis, crystal structure and magnetic characterisation of the trinuclear, fluoride-bridged, molecular nanomagnet [Dy(hfac)(3)(H2O)-CrF2(py)(4)-Dy(hfac)(3)(NO3)] (1) (hfacH = 1,1,1,5,5,5-hexafluoroacetylacetone, py = pyridine) and a closely related dinuclear species [Dy(hfac)(4)-CrF2( py)(4)]center dot 1/2 CHCl3 (2). Element-specific magnetisation curves obtained on 1 by X-ray magnetic circular dichroism (XMCD) allow us to directly observe the field-induced transition from a ferrimagnetic to a ferromagnetic arrangement of the Dy and Cr magnetic moments. By fitting a spin-Hamiltonian model to the XMCD data we extract a weak antiferromagnetic exchange coupling of j -0.18 cm(-1) between the Dy-III and Cr-III ions. The value found from XMCD is consistent with SQUID magnetometry and inelastic neutron scattering measurements. Furthermore, alternating current susceptibility and muon-spin relaxation measurements reveal that 1 shows thermally activated relaxation of magnetisation with a small effective barrier for magnetisation reversal of Delta(eff) 3 cm(-1). Density-functional theory calculations show that the Dy-Cr couplings originate from superexchange via the fluoride bridges.

"Say It Fast, Fluent and Flawless" : formulaicity in the oral language production of young foreign language learners
- 2017
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This thesis reports on a study, which investigated the process of early foreign language learning in a classroom context and the functions of multi-word units of language known as formulaic sequences in the oral language production of young foreign language learners. A classroom with 11 students in the age range 9 to 11 years was observed and video recorded for 16 sessions (90 minutes per session). The observations were accompanied by two elicitation tasks. 10 sessions out of the 16 sessions of the collected speech samples were transcribed chronologically. In the next step, formulaic sequences were identified based on pre-established criteria, which were further developed during the analysis. The data was analyzed in order to identify the functions of formulaic sequences in learners’ oral language production in addition to the inter-learner variations in the application of formulaic sequences for different functions.The results revealed evidence of incidental learning of formulaic sequences from input; the language input provided instances for the learners to learn multi-word units. In addition, formulaic sequences played different roles in the language production of the learners. These sequences helped young language learners to overcome their lack of knowledge, to improve their fluency, and to enjoy some language play. Formulaic sequences were used as a strategy to economize effort on processing and also to buy time for processing. The findings of the study suggested that language users might introduce dis-fluency in the production of their sequences in order to buy time for further processing. Moreover, the data provided examples illustrating communicative functions of formulaic sequences where the use of formulaic sequences was affected by the relationship between the speaker and listener. The analysis revealed that although all the learners applied formulaic sequences in their language production, there was a great variation among individual learners in their intention and the extent of the application of formulaic sequences. Some learners used these sequences to be able to extend their utterances and produce more of the language, whereas other learners used them to avoid further language production. In sum, it seemed that individual learners' different personalities, needs or limitations served as explanation for the application of formulaic sequences in different contexts.

HumaNetten Nr 48, våren 2022 : Educational Linguistics
- 2022
-
Samlingsverk (redaktörskap) (refereegranskat)abstract
- Under pågående pandemi och uppseendeväckande världshändelser fortsätter HumaNetten sin mission som spridare av humaniora i ordets bredare bemärkelse. Linnéuniversitetet har turen att ha en kader av driftiga språkforskare som tagit initiativet till flera artiklar och temanummer genom åren. I detta vårnummer har vi glädjen att se Daniel Ocic Ihrmark, Sergej Ivanov och Christian Waldmann som gästredaktörer för ett tema om Educational Linguistics, vilket kan översättas som utbildningsinriktad språkvetenskap. Det handlar om relationen mellan språk, tanke, kommunikation och kunskapsutveckling inom olika skol- och utbildnings-nivåer. Det är med andra ord en högst samhällsrelevant inriktning som förstärker bilden av humanioras roll i det moderna samhället. Den forskningsmiljö som utvecklats vid Linnéuniversitetet sammanför språkvetare och språkdidaktiker inom de olika språk som undervisas om vid universitetet. I det här temanumret presenteras tio studier med nya perspektiv på Educational Linguistics. Vi ska inte ge en detaljerad översikt över innehållet på denna plats eftersom gästredaktörerna ger en närmare presentation av temat i sin separata introduktion. Utanför huvudtemat publicerar Sara Snoder, doktorand i språkdidaktik, sin studie ”Utrymmen för flerspråkighet – funktionella aspekter av flerspråkiga låg- och mellanstadie-lärares språkliga praktiker”, där hon med en etnografisk ansats söker vinna ny kunskap om flerspråkig användning i skolundervisning.För redaktionens räkningHans Hägerdal
