- The demographic history of East-Central Europe after the Neolithic period remains poorly explored, despite this region being on the confluence of various ecological zones and cultural entities. Here, the descendants of societies associated with steppe pastoralists form Early Bronze Age were followed by Middle Bronze Age populations displaying unique characteristics. Particularly, the predominance of collective burials, the scale of which, was previously seen only in the Neolithic. The extent to which this re-emergence of older traditions is a result of genetic shift or social changes in the MBA is a subject of debate. Here by analysing 91 newly generated genomes from Bronze Age individuals from present Poland and Ukraine, we discovered that Middle Bronze Age populations were formed by an additional admixture event involving a population with relatively high proportions of genetic component associated with European hunter-gatherers and that their social structure was based on, primarily patrilocal, multigenerational kin-groups. By analysing 91 Bronze Age genomes from East-Central Europe, the authors discovered that Middle Bronze Age populations were formed by an admixture event involving hunter-gatherers and that the social structure of resulting population was primarily patrilocal.

- Objective: We aim to identify maternal genetic affinities between the Middle to Final Neolithic (3850-2300 BC) populations from present-day Poland and possible genetic influences from the Pontic steppe.Materials and methods: We conducted ancient DNA studies from populations associated with Zlota, Globular Amphora, Funnel Beaker, and Corded Ware cultures (CWC). We sequenced genomic libraries on Illumina platform to generate 86 complete ancient mitochondrial genomes. Some of the samples were enriched for mitochondrial DNA using hybridization capture.Results: The maternal genetic composition found in Zlota-associated individuals resembled that found in people associated with the Globular Amphora culture which indicates that both groups likely originated from the same maternal genetic background. Further, these two groups were closely related to the Funnel Beaker culture-associated population. None of these groups shared a close affinity to CWC-associated people. Haplogroup U4 was present only in the CWC group and absent in Zlota group, Globular Amphora, and Funnel Beaker cultures.Discussion: The prevalence of mitochondrial haplogroups of Neolithic farmer origin identified in Early, Middle and Late Neolithic populations suggests a genetic continuity of these maternal lineages in the studied area. Although overlapping in time - and to some extent - in cultural expressions, none of the studied groups (Zlota, Globular Amphora, Funnel Beaker), shared a close genetic affinity to CWC-associated people, indicating a larger extent of cultural influence from the Pontic steppe than genetic exchange. The higher frequency of haplogroup U5b found in populations associated with Funnel Beaker, Globular Amphora, and Zlota cultures suggest a gradual maternal genetic influx from Mesolithic hunter-gatherers. Moreover, presence of haplogroup U4 in Corded Ware groups is most likely associated with the migrations from the Pontic steppe at the end of the Neolithic and supports the observed genetic distances.

- Objective: In this work we aim to investigate the origins and genetic affinities of Bronze Age populations (2,400-1,100 BC) from the region of southern Poland and to trace maternal kinship patterns present in the burials of those populations by the use of complete mitochondrial genomes.Materials and methods: We performed ancient DNA analyses for Bronze Age individuals from present-day Poland associated with the Strzy(z) over dotow culture, the Mierzanowice culture, and the Trzciniec Cultural circle. To obtain complete mitochondrial genomes, we sequenced genomic libraries using Illumina platform. Additionally, hybridization capture was used to enrich some of the samples for mitochondrial DNA. AMS C-14-dating was conducted for 51 individuals to verify chronological and cultural attribution of the analyzed samples.Results: Complete ancient mitochondrial genomes were generated for 80 of the Bronze Age individuals from present-day Poland. The results of the population genetic analyses indicate close maternal genetic affinity between Mierzanowice, Trzciniec, and Corded Ware culture-associated populations. This is in contrast to the genetically more distant Strzy(z) over dotow people that displayed closer maternal genetic relation to steppe populations associated with the preceding Yamnaya culture and Catacomb culture, and with later Scythians. Potential maternal kinship relations were identified in burials of Mierzanowice and Trzciniec populations analyzed in this study.Discussion: Results revealed genetic continuity from the Late Neolithic Corded Ware groups to Bronze Age Mierzanowice and Trzciniec-associated populations, and possible additional genetic contribution from the steppe to the formation of the Strzy(z) over dotow-associated group at the end of 3rd millennium BC. Mitochondrial patterns indicated several pairs of potentially maternally related individuals mostly in Trzciniec-associated group.

- Recently, the COVID-19 pandemic impacted immensely on individuals and societies around the world. This study aimed at delineating Swedish middle school (10?12-year-old) pupils? understanding of bacteria and viruses, thereby illustrating the influence of the pandemic at schools and in society. Data was collected by semi-structured, individual interviews and by asking pupils to draw images. Thematic coding of interview transcripts and content analysis of pupils? annotated drawings were used. The morphology of microorganisms from the drawings was often 'corona-like', with a round shape and with protruding parts. Viruses were commonly considered larger than bacteria, but sometimes also similar in size. Interrelationships between bacteria and viruses were expressed with a superior microorganism. Pupils drew microorganisms as cell-like and never portrayed them as animals or with anthropomorphic features. Viruses were considered to cause a more severe disease than bacteria. Pupils seldomly tethered a specific virus to a specific infectious disease, and often named both (virus and disease) 'corona'. However, when they did make a connection, viruses were considered to cause flu and COVID-19, bacteria to cause cold and plague. In general, these results indicate that viruses received a more pronounced position amongst microorganisms in the minds of pupils in the aftermath of COVID-19.

Tidskriftsartikel (refereegranskat)abstract
- The COVID-19 pandemic had an immense impact on communities around the world. We know that new epidemic-prone diseases will emerge in the future. Consequently, it is important to investigate what impact the current pandemic had on school children’s understanding of infectious diseases in order to develop biology education based on that novel understanding. The aim of this study was to explore Swedish middle school (10-12-year-old) pupils’ understanding of infectious diseases and their perceived sources of knowledge. Data was collected through individual semi-structured interviews with fifteen pupils and analysed by thematic coding. Results revealed a great impact of the pandemic on the respondents’ conceptions. Firstly, their notion of infectious diseases based on their idea of COVID-19 was elusive because COVID-19 can manifest very differently. Secondly, the need to care about oneself and others was recognized. Thirdly, the importance of vaccines was recognized, but vaccines were given different roles. Finally, their understanding of infection seems to originate from informal domains such as the news and the Internet, rather than from biology education. One proposal for biology teaching could be to introduce scientific concepts earlier, to pay more attention to differences and similarities between infectious diseases, and to cooperate with other school subjects.

- For much of the past year the coronavirus 2019 (COVID-19) pandemic has had an enormous impact on the lives of individuals and communities around the world. The aims of the current study was to investigate (I) 10 to 12-year-old Swedish pupils´ views on how the ongoing COVID-19 pandemic influences their interests and understanding regarding contagion literacy (CL), and (II) from what source (biology education or informal settings) they perceive that their knowledge originates from. The study is based on the framework of CL that was defined as the health literacy required in daily life and that recommends what should be taught at compulsory schools. The framework specifies six content themes, of which four are used in the current study to outline middle school pupils´ comprehension. Data is collected by individual, semi-structured interviews with pupils´ at schools located in various socio-economic areas. The interviews were transcribed and analysed thematically. Preliminary results showed that pupils´ perceive the ongoing pandemic to prompt many student-initiated questions and is creating more interactive and interesting learning situations. Most pupils say they have no experience CL from their formal biology teaching and that their knowledge derives mostly from sources outside school, such as news programs for children. To conclude, the interviewed Swedish middle school pupils´ understanding of CL seems mainly to originate from informal domains, rather than from formal biology education. Hence, the results indicate that the COVID-19 pandemic spark interest among pupils for the topic and that there is a potential for exploiting this interest in developing biology education at this school level.

- For the past couple of years, the COVID-19 pandemic had an immense impact on lives of individuals and societies around the world. The main purpose of this study was to delineate Swedish middle school (10-12-year-old) pupils’ understanding of bacteria and virus thereby illustrating the impact of the pandemic at schools and in society. Data were collected by semistructured, individual interviews and by asking participants to draw images of bacteria and virus. Thematic coding and content analysis of children’s annotated drawings were used. The morphology of the microorganisms from the drawings was analyzed by the deductively induced themes shape, surface texture and internal feature. Viruses were frequently considered larger than bacteria, but it was also common to view them being similar in size. Interrelationships between bacteria and viruses were expressed like a hierarchy with a “superior” microorganism, and as bacteria could generate viruses. Pupils drew microorganisms as cell-like and never portrayed them as animals or with anthropomorphic features, as reported in earlier research. Metaphoric aspects of drawings of viruses were summarized as being “bacteriophage-like” or “corona-like”. A virus was considered to induce the more grievous disease. Pupils seldomly tethered a specific virus to a specific infectious disease, and often named both "corona". However, when they did so, virus was tethered to flu and COVID-19 and bacteria to cold and plague. One ostensible suggestion for learning improvement would be to pay more attention to differences between microorganisms and their liaison to specific infectious diseases. This liaison is suggested as an important concept for developing contagion literacy. Furthermore, we recommend pathogenic bacteria and viruses to be explicitly taught in biology education at middle school or earlier in balance with knowledge about essential microorganisms. Finally, we propose the measures above to be integrated into the biology education of teacher´s education.

Tidskriftsartikel (refereegranskat)abstract
- Volt hockey is a team sport developed for persons with physical disabilities, but its influence on well-being is unknown. Elements of well-being have been described as positive emotions, engagement, relationships, meaning, and achievement constituting a theoretical framework referred to as PERMA. The purpose of this study was to describe how well-being according to PERMA is reflected in the experiences of playing volt hockey. Data were collected through focus group and individual interviews including 21 players. A deductive analysis was conducted using the elements in PERMA as preexisting main categories with an additional main category, named resources needed. Findings showed that all five elements constituting well-being according to PERMA were reflected in the experiences of playing volt hockey. In addition, players emphasized the importance of having the resources needed to play volt hockey. In conclusion, having the opportunity to enjoy playing volt hockey enabled the players to flourish and experience feelings of subjective well-being.

- Volt hockey is a team sport developed for persons with physical disabilities. Because family members are important resources to enable sports participation, the purpose of this study was to illuminate experiences of volt hockey from family members’ perspectives. Focus group interviews were conducted, including 20 family members, and the verbatim transcripts were inductively analysed using reflexive thematic analysis. Family members saw the value of enabling participation in volt hockey, being an inclusive team sport that brings enjoyment and strengthens social relationships within, and outside of, the family. Trying to facilitate sport participation, the need for material resources and other actors was emphasised, such as personal assistance, funders, and healthcare professionals informing about the sport and the engagement of the volt hockey clubs. In conclusion, involvement in volt hockey is emotionally and socially rewarding for family members, but there is a need for additional enablers to allow the sport to grow.
