Attitudes and beliefs on multilingualism in education : voices from Sweden

Sweden is often commended for the inclusion of home languages in the formal education system: both mother tongue instruction (where a pupil’s home language is taught as an optional school subject) and study guidance (where a pupil is given content support in their home language or prior language of schooling) are offered. Still, while many national educational policies are supportive of multilingualism, their enactment on the ground is often problematic. The attitudes and beliefs of teacher educators, in-service teachers, and pre-service teachers are crucial here, yet few studies have investigated how these key actors in Sweden perceive their encounters with linguistic diversity. Furthermore, an understanding of the similarities and differences in the perspectives across these three cohorts is lacking. We have analysed interviews with five teacher educators, five in-service teachers, and eight pre-service teachers concerning their attitudes and beliefs on multilingualism. These interviews reveal orientations towards language and language use in teacher education and primary schools. Specifically, language is seen both as a problem and as a resource. Our results uncover tensions in the expressed attitudes and beliefs about multilingualism, as well as about multilingual pre-service teachers in teacher education and multilingual pupils in the Swedish school

Community proteogenomics reveals insights into the physiology of phyllosphere bacteria

Aerial plant surfaces represent the largest biological interface on Earth and provide essential services as sites of carbon dioxide fixation, molecular oxygen release, and primary biomass production. Rather than existing as axenic organisms, plants are colonized by microorganisms that affect both their health and growth. To gain insight into the physiology of phyllosphere bacteria under in situ conditions, we performed a culture-independent analysis of the microbiota associated with leaves of soybean, clover, and Arabidopsis thaliana plants using a metaproteogenomic approach. We found a high consistency of the communities on the 3 different plant species, both with respect to the predominant community members (including the alphaproteobacterial genera Sphingomonas and Methylo bacterium) and with respect to their proteomes. Observed known proteins of Methylobacterium were to a large extent related to the ability of these bacteria to use methanol as a source of carbon and energy. A remarkably high expression of various TonB-dependent receptors was observed for Sphingomonas. Because these outer membrane proteins are involved in transport processes of various carbohydrates, a particularly large substrate utilization pattern for Sphingomonads can be assumed to occur in the phyllosphere. These adaptations at the genus level can be expected to contribute to the success and coexistence of these 2 taxa on plant leaves. We anticipate that our results will form the basis for the identification of unique traits of phyllosphere bacteria, and for uncovering previously unrecorded mechanisms of bacteria-plant and bacteria-bacteria relationships
