- Teachers are pivotal in creating safe and efficacious learning environments for ethnic minority students. Research suggests that teachers' multicultural attitudes, self-efficacy, and wellbeing at work may all play important roles in this endeavor. Using survey data on 433 teachers in Belgium, Denmark, Finland, Norway, Sweden, and the United Kingdom, the present study used structural equation models to analyze the paths between teachers' multicultural attitudes and work-related wellbeing (work dedication and exhaustion), and whether self-efficacy mediates these paths. We further investigated how these associations differ between teachers of reception classes for migrant and refugee students versus teachers of multi-ethnic mainstream classes. The results show that positive multicultural attitudes were directly associated with high level of work dedication, but not with work exhaustion. Self-efficacy mediated the association between multicultural attitudes and work-related wellbeing, indicated by both higher work dedication and lower work exhaustion. Concerning the role of teacher's class type, self-efficacy mediated the association between positive multicultural attitudes and work dedication for both types of teachers, whereas the mediation to low work exhaustion was only evident in mainstream class teachers. To conclude, teachers' multicultural attitudes and work-related wellbeing are mediated by self-efficacy and this important link should be acknowledged when designing professional development programs in order to create supportive and competent learning environments for all students.

- Oxygen-stratified lakes are typical for the boreal zone and also a major source of greenhouse gas emissions in the region. Due to shallow light penetration, restricting the growth of phototrophic organisms, and large allochthonous organic carbon inputs from the catchment area, the lake metabolism is expected to be dominated by heterotrophic organisms. In this study, we test this assumption and show that the potential for autotrophic carbon fixation and internal carbon cycling is high throughout the water column. Further, we show that during the summer stratification carbon fixation can exceed respiration in a boreal lake even below the euphotic zone. Metagenome-assembled genomes and 16S profiling of a vertical transect of the lake revealed multiple organisms in an oxygen-depleted compartment belonging to novel or poorly characterized phyla. Many of these organisms were chemolithotrophic, potentially deriving their energy from reactions related to sulfur, iron, and nitrogen transformations. The community, as well as the functions, was stratified along the redox gradient. The autotrophic potential in the lake metagenome below the oxygenic zone was high, pointing toward a need for revising our concepts of internal carbon cycling in boreal lakes. Further, the importance of chemolithoautotrophy for the internal carbon cycling suggests that many predicted climate changeassociated fluctuations in the physical properties of the lake, such as altered mixing patterns, likely have consequences for the whole-lake metabolism even beyond the impact to the phototrophic community. IMPORTANCE Autotrophic organisms at the base of the food web are the only life form capable of turning inorganic carbon into the organic form, facilitating the survival of all other organisms. In certain environments, the autotrophic production is limited by environmental conditions and the food web is supported by external carbon inputs. One such environment is stratified boreal lakes, which are one of the biggest natural sources of greenhouse gas emissions in the boreal region. Thus, carbon cycling in these habitats is of utmost importance for the future climate. Here, we demonstrate a high potential for internal carbon cycling via phototrophic and novel chemolithotrophic organisms in the anoxic, poorly illuminated layers of a boreal lake. Our results significantly increase our knowledge on the microbial communities and their metabolic potential in oxygen-depleted freshwaters and help to understand and predict how climate change-induced alterations could impact the lake carbon dynamics.

- The vertical structuring of methanotrophic communities and its genetic controllers remain understudied in the water columns of oxygen-stratified lakes. Therefore, we used 16S rRNA gene sequencing to study the vertical stratification patterns of methanotrophs in two boreal lakes, Lake Kuivajarvi and Lake Lovojarvi. Furthermore, metagenomic analyses were performed to assess the genomic characteristics of methanotrophs in Lovojarvi and the previously studied Lake Alinen Mustajarvi. The methanotroph communities were vertically structured along the oxygen gradient. Alphaproteobacterial methanotrophs preferred oxic water layers, while Methylococcales methanotrophs, consisting of putative novel genera and species, thrived, especially at and below the oxic-anoxic interface and showed distinct depth variation patterns, which were not completely predictable by their taxonomic classification. Instead, genomic differences among Methylococcales methanotrophs explained their variable vertical depth patterns. Genes in clusters of orthologous groups (COG) categories L (replication, recombination and repair) and S (function unknown) were relatively high in metagenome-assembled genomes representing Methylococcales clearly thriving below the oxic-anoxic interface, suggesting genetic adaptations for increased stress tolerance enabling living in the hypoxic/anoxic conditions. By contrast, genes in COG category N (cell motility) were relatively high in metagenome-assembled genomes of Methylococcales thriving at the oxic-anoxic interface, which suggests genetic adaptations for increased motility at the vertically fluctuating oxic-anoxic interface.

- While scholarly literature indicates that both refugee and non-refugee migrant young people display increased levels of psychosocial vulnerability, studies comparing the mental health of the two groups remain scarce. This study aims to further the existing evidence by examining refugee and non-refugee migrants' mental health, in relation to their migration history and resettlement conditions. The mental health of 883 refugee and 483 non-refugee migrants (mean age 15.41, range 11-24, 45.9% girls, average length of stay in the host country 3.75 years) in five European countries was studied in their relation to family separation, daily material stress and perceived discrimination in resettlement. All participants reported high levels of post-traumatic stress symptoms. Family separation predicted post-trauma and internalizing behavioral difficulties only in refugees. Daily material stress related to lower levels of overall well-being in all participants, and higher levels of internalizing and externalizing behavioral difficulties in refugees. Perceived discrimination was associated with increased levels of mental health problems for refugees and non-refugee migrants. The relationship between perceived discrimination and post-traumatic stress symptoms in non-refugee migrants, together with the high levels of post-traumatic stress symptoms in this subsample, raises important questions on the nature of trauma exposure in non-refugee migrants, as well as the ways in which experiences of discrimination may interact with other traumatic stressors in predicting mental health.

- This article investigates school belonging among migrant students and how this changed during the Covid‐19 pandemic.Drawing on quantitative data gathered from 751 migrant students in secondary schools in six European countries (Belgium,Denmark, Finland, Norway, Sweden, and the UK), we examined the impact of Covid‐19 school closures, social support, andpost‐traumatic stress symptoms on changes in school belonging. Linear regression showed a non‐significant decrease inschool belonging, and none of the studied variables had a significant effect on this change in our whole sample. However,sensitivity analysis on a subsample from three countries (Denmark, Finland, and the UK) showed a small but significantnegative effect of increasing post‐traumatic stress symptoms on school belonging during Covid‐19 school closures. Giventhat scholarship on school belonging during Covid‐19 is emergent, this study delineates some key areas for future researchon the relationship between wellbeing, school belonging, and inclusion.
