- INTRODUCTION: Type 1 diabetes (T1D) is caused by the destruction of pancreatic islet beta cells resulting in total loss of insulin production. Recent studies have suggested that the destruction may be interrelated to plasma lipids.OBJECTIVES: Specific lipids have previously been shown to be decreased in children who develop T1D before four years of age. Disturbances of plasma lipids prior to clinical diagnosis of diabetes, if true, may provide a novel way to improve prediction, and monitor disease progression.METHODS: A lipidomic approach was utilized to analyze plasma from 67 healthy adolescent subjects (10-15 years of age) with or without islet autoantibodies but all with increased genetic risk for T1D. The study subjects were enrolled at birth in the Diabetes Prediction in Skåne (DiPiS) study and after 10-15 years of follow-up we performed the present cross-sectional analysis. HLA-DRB345, -DRB1, -DQA1, -DQB1, -DPA1 and -DPB1 genotypes were determined using next generation sequencing. Lipidomic profiles were determined using ultra-high-performance liquid chromatography quadrupole time-of-flight mass spectrometry. Lipidomics data were analyzed according to genotype.RESULTS: Variation in levels of several specific phospholipid species were related to level of autoimmunity but not development of T1D. Five glycosylated ceramides were increased in insulin autoantibody (IAA) positive adolescent subjects compared to adolescent subjects without this autoantibody. Additionally, HLA genotypes seemed to influence levels of long chain triacylglycerol (TG).CONCLUSION: Lipidomic profiling of adolescent subjects in high risk of T1D may improve sub-phenotyping in this high risk population.

Journal article (peer-reviewed)abstract
- Chronic, low intensity herbivory by invertebrates, termed background herbivory, has been understudied in tundra, yet its impacts are likely to increase in a warmer Arctic. The magnitude of these changes is however hard to predict as we know little about the drivers of current levels of invertebrate herbivory in tundra. We assessed the intensity of invertebrate herbivory on a common tundra plant, the dwarf birch (Betula glandulosa-nana complex), and investigated its relationship to latitude and climate across the tundra biome. Leaf damage by defoliating, mining and gall-forming invertebrates was measured in samples collected from 192 sites at 56 locations. Our results indicate that invertebrate herbivory is nearly ubiquitous across the tundra biome but occurs at low intensity. On average, invertebrates damaged 11.2% of the leaves and removed 1.4% of total leaf area. The damage was mainly caused by external leaf feeders, and most damaged leaves were only slightly affected (12% leaf area lost). Foliar damage was consistently positively correlated with mid-summer (July) temperature and, to a lesser extent, precipitation in the year of data collection, irrespective of latitude. Our models predict that, on average, foliar losses to invertebrates on dwarf birch are likely to increase by 6-7% over the current levels with a 1 degrees C increase in summer temperatures. Our results show that invertebrate herbivory on dwarf birch is small in magnitude but given its prevalence and dependence on climatic variables, background invertebrate herbivory should be included in predictions of climate change impacts on tundra ecosystems.

Species and abundance of ectoparasitic flies (Diptera) in pied flycatcher nests in Fennoscandia
- 2015
-
In: Parasites & Vectors. - : BioMed Central. - 1756-3305. ; 8
-
Journal article (peer-reviewed)abstract
- Background: Birds host several ectoparasitic fly species with negative effects on nestling health and reproductive output, and with the capability of transmitting avian blood parasites. Information on the abundance and distribution of the ectoparasitic fly genera Ornithomya (Hippoboscidae) and Protocalliphora (Calliphoridae) in northern Europe is still generally poor, and we thus explored their geographic range and occurrence of these flies in the nests of a common avian model species, the pied flycatcher Ficedula hypoleuca. Methods: Nests of F. hypoleuca were collected from 21 locations across Fennoscandia in summer 2013, across a latitudinal gradient (between 56 degrees N - 70 degrees N) and examined for the presence of fly puparia. Adult specimens of Ornithomya spp. were also collected for species identification. Fly species were identified morphologically and identifications confirmed with DNA barcoding. Results: We found three species: two louse-flies - Ornithomya chloropus and O. avicularia - and one blow-fly, Protocalliphora azurea. The prevalence of O. avicularia was higher in southern latitudes and this species was not encountered beyond 62 degrees N whereas O. chloropus and P. azurea occurred across the whole range of latitudes. The prevalence of O. chloropus further increased with increasing distance from the coast - a pattern not documented before. The three fly species showed no interspecific associations in their prevalence. Conclusions: Our study revealed relatively high prevalence for all the species (O. chloropus 59 %, O. avicularia 20 %, P. azurea 32 %), and an interesting spatial pattern in the prevalence of the two louse fly species. Our sample did not indicate any major range shifts towards the north for the southern species as compared to the information from the past. Morphological identification of O. chloropus did not match with the corresponding sequences published in the GenBank and taxonomy of this group calls for further studies.

Conference paper (other academic/artistic)abstract
- Titel: Hybridundervisning vid Konstnärliga fakulteten Bakgrund: Enligt Hilli (2016) finns det motstridig forskning om hur väl det går att skapa en känsla av gemenskap i virtuella lärmiljöer. Vuopalas (2013) menar att denna känsla är svår att uppnå i synnerhet om undervisningen sker på distans. Ett kompetensutvecklingsprojekt har genom-förts under våren 2021 på institutionerna HDK-Valand (Högskolan för konst och design) och HSM (Högskolan för scen och musik) för att främja digital kompetens kring hybridundervisning bland undervisande personal vid Konstnärliga fakulteten. Projektet Hybridundervisning vid Konstnärliga fakulteten har syftat till att genom utvecklingsarbete med samtidig nätburen undervisning på campus och distans utprova metoder där fem deltagande lärare undersökt olika villkor, möjligheter och begränsningar i användandet av hybridundervisning, främst inom de estetiska ämnena inom lärarutbildning. Frågeställning: Hur uppfattar studenter hybridundervisning och vilka möjligheter respektive svårigheter ser de med denna undervisningsform? Vilka konsekvenser får avsaknaden av direkt interaktion i en fysisk miljö, exempelvis i form av samspelsmöjligheter för studenternas lärande och vilken betydelse har deras förkunskaper i detta sammanhang? Beskrivning av presentationen: Genomförandet av utvecklingsprojektet har skett genom komparativa jämförelser i form av likheter och skillnader mellan undervisning i olika kurser. De deltagande lärarna har samman-ställt sina resultat från sina utprövningar utifrån centrala teman som varit gemensamma i projektet, som relationen mellan det analoga och det digitala samt individuella och gruppunder-visningsmoment, användandet av olika verktyg och teknik, men också exempelvis tidsaspekter och rumslighet (lärmiljön), lärarrollen och det kommunikativa liksom förförståelse och erfarenhet (kroppslighet, tyst och uttalad kunskap) (Polanyi, 1966; Molander, 1996). Olika metoder har utprovats i undervisning i bild, drama, musik och didaktiska studier med estetisk inriktning, som i denna föredragning beskrivs genom två fallstudier från dels kompetensutveckling kring pedagogisk handledning för lärare i förskola/grundskola och musiklärarutbildning. Exempel ges utifrån observationer från distansundervisning i grupp i brukspiano i relation till den tekniska begränsning som omöjliggör samspel mellan studenterna i realtid över internet. Av tradition har instrumentalundervisning oftast skett i form av enskild undervisning. Dock har gruppundervisning kommit att bli betydligt vanligare under senare år. Erfarenheterna i projektet visar att vissa studenter med mindre förkunskaper än andra i gruppen har en risk att inte utveckla sitt lärande lika mycket som de som har större förkunskaper. De möjligheter till lärande som kan ske i form av utbyte av metoder, erfarenheter, inspiration och stöttning när studenterna musicerar tillsammans går förlorade i detta sammanhang. Det kan därför finnas behov av att diskutera vad just samspelet har för betydelse för studenternas lärande på sina instrument.

“When neo-Nazis march on Norwegian streets, you hear a lot of Swedish”: Pan-Nordic and transnational dimensions of right-wing extremism
- 2023
-
Reports (other academic/artistic)abstract
- This report constitutes the first comprehensive review of right-wing extremism (RWE) in the Nordics (Denmark, Finland, Norway, and Sweden). In it, a team of 13 leading researchers have compiled and reviewed academic texts written about the topic. The result is a descriptive and analytical report of how the Nordic RWE milieu has developed from 1918 until today, with a specific focus on the pan-Nordic and transnational dimensions of the milieu. In the report, we also compile the practices used to prevent RWE in the Nordics, and analyze how well they are situated to handle the threat RWE poses to society.

Hiding in the background : community-level patterns in invertebrate herbivory across the tundra biome
- 2019
-
In: Polar Biology. - : Springer. - 0722-4060 .- 1432-2056. ; 42:10, s. 1881-1897

Journal article (peer-reviewed)abstract
- Invertebrate herbivores depend on external temperature for growth and metabolism. Continued warming in tundra ecosystems is proposed to result in increased invertebrate herbivory. However, empirical data about how current levels of invertebrate herbivory vary across the Arctic is limited and generally restricted to a single host plant or a small group of species, so predicting future change remains challenging. We investigated large-scale patterns of invertebrate herbivory across the tundra biome at the community level and explored how these patterns are related to long-term climatic conditions and year-of-sampling weather, habitat characteristics, and aboveground biomass production. Utilizing a standardized protocol, we collected samples from 92 plots nested within 20 tundra sites during summer 2015. We estimated the community-weighted biomass lost based on the total leaf area consumed by invertebrates for the most common plant species within each plot. Overall, invertebrate herbivory was prevalent at low intensities across the tundra, with estimates averaging 0.94% and ranging between 0.02 and 5.69% of plant biomass. Our results suggest that mid-summer temperature influences the intensity of invertebrate herbivory at the community level, consistent with the hypothesis that climate warming should increase plant losses to invertebrates in the tundra. However, most of the observed variation in herbivory was associated with other site level characteristics, indicating that other local ecological factors also play an important role. More details about the local drivers of invertebrate herbivory are necessary to predict the consequences for rapidly changing tundra ecosystems.

A physico-chemical characterisation of new raw materials for microcrystalline cellulose manufacturing
- 2012

In: Cellulose. - : Springer Science and Business Media LLC. - 0969-0239 .- 1572-882X. ; 19:1, s. 219-235

Journal article (peer-reviewed)abstract
- A detailed physico-chemical characterisation of potential new cellulose sources (rice husk, hemp stalk, and coniferous needles), and microcrystalline cellulose (MCC) manufactured from them, was made in this work. The length and the width of the cellulose crystallites were determined by wide-angle X-ray scattering (WAXS), crystallinities were studied by means of WAXS and solid state cross polarisation magic angle spinning (13)C nuclear magnetic resonance (NMR) spectroscopy, and the packing and the cross-sectional shape of the microfibrils were determined by small-angle X-ray scattering. When MCC was prepared from rice husks and hemp stalks an acceptable yield was obtained. Crystallinities obtained with solid state NMR spectroscopy and WAXS were highest for MCC prepared from hemp stalks, and lowest for rice husk MCC. The crystallite sizes of MCC samples studied in this work varied more than in those MCC samples which were prepared from conventional plant sources, and crystallite size and cellulose crystallinity were related. When taking into account rather high values of specific surface, hemp stalks and rice husks appear as a promising raw materials for MCC production.
