- Background: Medical simulation enables the design of learning activities for competency areas (eg, communication and leadership) identi ed as crucial for future health care professionals. Simulation educators and medical teachers follow different career paths, and their education backgrounds and teaching contexts may be very different in a simulation setting. Although they have a key role in facilitating learning, information on the continuing professional development (pedagogical development) of simulation educators is not available in the literature. Objectives: To explore changes in experienced simulation educators’ perceptions of their own teaching skills, practices, and understanding of teaching over time.Methods: A qualitative exploratory study. Fourteen experienced simulation educators partici- pated in individual open-ended interviews focusing on their development as simulation educators. Data were analyzed using an inductive thematic analysis. Results: Marked educator development was discerned over time, expressed mainly in an altered way of thinking and acting. Five themes were identi ed: shifting focus, from following to utilizing a structure, setting goals, application of technology, and alignment with profession. Being con dent in the role as an instructor seemed to constitute a foundation for the instructor’s pedagogical development.Conclusion: Experienced simulation educators’ pedagogical development was based on self- con dence in the educator role, and not on a deeper theoretical understanding of teaching and learning. This is the rst clue to gain increased understanding regarding educational level and possible education needs among simulation educators, and it might generate several lines of research for further studies.

Animal horror cinema : genre, history and criticism
- 2015
-
Proceedings (redaktörskap) (övrigt vetenskapligt/konstnärligt)abstract
- The first academic study of the genre of animal horror cinema is essential for cinema and animal studies scholars as well as for fans of horror film. It defines this popular sub-genre, outlines its history and studies recent films as well as cult classics from a variety of perspectives. A central idea in the book is that animal horror cinema mirrors socially entrenched fears of and attitudes toward animals. Thus, animal horror cinema reveals attitudes toward the fabric of social life, the fragility of the eco-system and a deep uncertainty about what makes humans different from animals. The book contains chapters by scholars with different national and disciplinary backgrounds, and therefore offers a wide range of interpretations on the significance of the animal in modern horror film.

- Fish skin-associated microbial communities are highly variable among populations and species and can impact host fitness. Still, the sources of variation in microbiome composition, and particularly how they vary among and within host individuals, have rarely been investigated. To tackle this issue, we explored patterns of variation in fish skin microbiomes across different spatial scales. We conducted replicate sampling of dorsal and ventral body sites of perch (Perca fluviatilis) from two populations and characterized the variation of fish skin-associated microbial communities with 16S rRNA gene metabarcoding. Results showed a high similarity of microbiome samples taken from the left and right side of the same fish individuals, suggesting that fish skin microbiomes can be reliably assessed and characterized even using a single sample from a specific body site. The microbiome composition of fish skin differed markedly from the bacterioplankton communities in the surrounding water and was highly variable among individuals. No ASV was present in all samples, and the most prevalent phyla, Actinobacteria, Bacteroidetes, and Proteobacteria, varied in relative abundance among fish hosts. Microbiome composition was both individual- and population specific, with most of the variation explained by individual host. At the individual level, we found no diversification in microbiome composition between dorsal and ventral body sites, but the degree of intra-individual heterogeneity varied among individuals. To identify how genetic and phenotypic characteristics of fish hosts impact the rate and nature of intra-individual temporal dynamics of the skin microbiome, and thereby contribute to the host-specific patterns documented here, remains an important task for future research.

Bibliotekarier i teori och praktik : utbildningsperspektiv på en unik profession
- 2018
-
Samlingsverk (redaktörskap) (övrigt vetenskapligt/konstnärligt)abstract
- I den ständigt närvarande diskussionen om bibliotekarieprofessionens innehåll och utveckling finns återkommande frågan om utbildningens roll. I takt med att samhället blir alltmer komplext söker också biblioteken en breddad bas av kompetenser för sin verksamhet, något som gör att bibliotekariens grundkompetens ibland ter sig otydlig. Ofta talas det om ett "glapp" mellan det utbildningsbehov som finns i bibliotekens praktiska vardag och det innehåll som bjuds inom de biblioteks- och informationsvetenskapliga utbildningarna.I den här antologin samlas ett tjugotal bibloteks- och informationsvetenskapliga forskare och diskuterar sina specialområdens relevans för bibliotekariernas praktiska arbete. Grundfrågan är enkel: på vilket sätt bidrar en biblioteks- och informationsvetenskaplig utbildning och forskning till en stärkt bibliotekarieprofession? Svaret ges genom betraktelser av bibliotekariens professionsutövning utifrån ett renodlat utbildningsperspektiv. Bilden som framträder är bred och mångfacetterad. Ämnesområden som medie- och informationskunskap, bibliometri, professionellt språkbruk, praktikens betydelse i utbildningen, professionsetik, den historiska utvecklingen av bibliotekarieutbildningen i Sverige samt arbete med aktuella samhällsutmaningar är bara några av de teman som tas upp.Frågor som rör relationen mellan forskning, utbildning och praktik i dagens biblioteksvärld diskuteras genom exempel och en unik bild av bibliotekarienas professionella identitet träder fram. Bokens texter ställer också den egna verksamheten, bibliotekarieutbildningen, i ett kritiskt ljus och diskuterar hur en utveckling kan ske inom de ramar som styr utbildningens och forskningens möjligheter.

- Extended Spectrum beta-Lactamase (ESBL) producing Enterobacteriaceae started to appear in the 1980s, and have since emerged as some of the most significant hospital-acquired infections with Escherichia coli and Klebsiella being main players. More than 100 different ESBL types have been described, the most widespread being the CTX-M beta-lactamase enzymes (bla(CTX-M) genes). This study focuses on the zoonotic dissemination of ESBL bacteria, mainly CTX-M type, in the southern coastal region of France. We found that the level of general antibiotic resistance in single randomly selected E. coli isolates from wild Yellow-legged Gulls in France was high. Nearly half the isolates (47,1%) carried resistance to one or more antibiotics (in a panel of six antibiotics), and resistance to tetracycline, ampicillin and streptomycin was most widespread. In an ESBL selective screen, 9,4% of the gulls carried ESBL producing bacteria and notably, 6% of the gulls carried bacteria harboring CTX-M-1 group of ESBL enzymes, a recently introduced and yet the most common clinical CTX-M group in France. Multi locus sequence type and phylogenetic group designations were established for the ESBL isolates, revealing that birds and humans share E. coli populations. Several ESBL producing E. coli isolated from birds were identical to or clustered with isolates with human origin. Hence, wild birds pick up E. coli of human origin, and with human resistance traits, and may accordingly also act as an environmental reservoir and melting pot of bacterial resistance with a potential to re-infect human populations.

Forskningsöversikt (refereegranskat)abstract
- There is a lack of research on older lesbian, gay, bisexual, transgender, and queer/questioning (LGBTQ) adults. This systematic review aimed to synthesize Japanese and Swedish qualitative research on LGBTQ adults aged 60 years or older following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Japanese and Swedish articles, published in English, were searched across ASSIA, CINAHL, Medline, PsychINFO, PubMed, Scopus, and Sociological Abstracts databases. Additional searches were conducted to include studies in Japanese or Swedish. There were no papers from Japan, whereas five from Sweden were reviewed. One article was excluded due to the wrong phenomenon. Four articles were included, involving 48 participants aged 60–94 years. We summarized the findings using a deductive thematic synthesis. Two major themes emerged: (a) quality of life, minority joy, and resilience (positive aspects), and (b) discrimination, stigmatization, and minority stress (negative aspects). The participants wished to be acknowledged for their own assets and unique life histories, and to be treated as everyone else. They emphasized the importance of knowledge of LGBTQ issues among nursing staff, so that older LGBTQ people are treated in a competent and affirmative way. The study revealed several important topics for understanding older LGBTQ adults’ life circumstances and the severe lack of qualitative studies in Japan and Sweden.

- Low-pathogenic avian influenza (LPAI) viruses in wild birds are important as they can constitute the basis for the development of highly pathogenic avian influenza viruses or form part of human-adapted strains with pandemic potential. However, the pathogenesis of LPAI viruses is not well characterized in dabbling ducks, one of the natural reservoirs of LPAI viruses. Between 21 September 2009 and 21 December 2009, we used real-time reverse transcriptase polymerase chain reaction (q-PCR), histopathology, and immunohistochemistry (IHC) to study Mallards (Anas platyrhynchos) infected with an influenza A/H1N1 virus isolated from a wild Mallard in Sweden. The ducks were either inoculated intraesophageally ("artificial infection") or infected by virus shed by other ducks in the experiment ("contact infection"). The ducks were subjected to three low concentrations (80 ng/L, 1 mu g/L, and 80 mu g/L) of the active metabolite of oseltamivir (Tamiflu (R)), oseltamivir carboxylate (OC), which resulted in the development of the viral resistance mutation H274Y at 1 and 80 mu g/L. The LPAI virus infection was localized to the intestinal tract and cloacal bursa except in one Mallard. The exception was a duck euthanized 1 day postinoculation, whose infection was located solely in the lung, possibly due to intratracheal deposition of virus. The intestinal infection was characterized by occasional degenerating cells in the lamina propria and presence of viral antigen as detected by IHC, as well as positive q-PCR performed on samples from feces and intestinal contents. Histopathologic changes, IHC positivity, and viral shedding all indicated that the infection peaked early, around 2 days postinfection. Furthermore, more viral antigen and viral RNA were detected with IHC and q-PCR in the proximal parts early in the infection. There was no obvious difference in the course of the infection in artificial versus contact infection, when the level of OC was increased from 80 ng/L to 1 mu g/L (based on IHC and q-PCR), when the level of OC was increased to 80 mu/L, or when the resistance mutation H274Y developed (based on q-PCR).

Spatio-Temporal Interdependence of Bacteria and Phytoplankton during a Baltic Sea Spring Bloom

Tidskriftsartikel (refereegranskat)abstract
- In temperate systems, phytoplankton spring blooms deplete inorganic nutrients and are major sources of organic matter for the microbial loop. In response to phytoplankton exudates and environmental factors, heterotrophic microbial communities are highly dynamic and change their abundance and composition both on spatial and temporal scales. Yet, most of our understanding about these processes comes from laboratory model organism studies, mesocosm experiments or single temporal transects. Spatial -temporal studies examining interactions of phytoplankton blooms and bacterioplankton community composition and function, though being highly informative, are scarce. In this study, pelagic microbial community dynamics (bacteria and phytoplankton) and environmental variables were monitored during a spring bloom across the Baltic Proper (two cruises between North Germany to Gulf of Finland). To test to what extent bacterioplankton community composition relates to the spring bloom, we used next generation amplicon sequencing of the 16S rRNA gene, phytoplankton diversity analysis based on microscopy counts and population genotyping of the dominating diatom Skeletonema rnarinoi. Several phytoplankton bloom related and environmental variables were identified to influence bacterial community composition. Members of Bacteroidetes and Alphaproteobacteria dominated the bacterial community composition but the bacterial groups showed no apparent correlation with direct bloom related variables. The less abundant bacterial phyla Actinobacteria, Planctomycetes, and Verrucomicrobia, on the other hand, were strongly associated with phytoplankton biomass, diatom:dinoflagellate ratio, and colored dissolved organic matter (cDOM). Many bacterial operational taxonomic units (OTUs) showed high niche specificities. For example, particular Bacteroidetes OTUs were associated with two distinct genetic clusters of S. marinoi. Our study revealed the complexity of interactions of bacterial taxa with inter- and intraspecific genetic variation in phytoplankton. Overall, our findings imply that biotic and abiotic factors during spring bloom influence bacterial community dynamics in a hierarchical manner.

Expression Levels of hgcAB Genes and Mercury Availability Jointly Explain Methylmercury Formation in Stratified Brackish Waters

- Neurotoxic methylmercury (MeHg) is formed by microbial methylation of inorganic divalent Hg (Hg-II) and constitutes severe environmental and human health risks. The methylation is enabled by hgcA and hgcB genes, but it is not know nif the associated molecular-level processes are rate-limiting or enable accurate prediction of MeHg formation in nature. In this study, we investigated the relationships between hgc genes and MeHg across redox-stratified water columns in the brackish Baltic Sea. We showed, for the first time, that hgc transcript abundance and the concentration of dissolved Hg-II-sulfide species were strong predictors of both the Hg-II methylation rate and MeHg concentration, implying their roles as principal joint drivers of MeHg formation in these systems. Additionally, we characterized the metabolic capacities of hgc(+) microorganisms by reconstructing their genomes from metagenomes (i.e., hgc(+) MAGs), which highlighted the versatility of putative Hg-II methylators in the water column of the Baltic Sea. In establishing relationships between hgc transcripts and the Hg-II methylation rate, we advance the fundamental understanding of mechanistic principles governing MeHg formation in nature and enable refined predictions of MeHg levels in coastal seas in response to the accelerating spread of oxygen-deficientzones.
