Archaeological and Historical Materials as a Means to Explore Finnish Crop History

ABSTRACT

In Northern Europe, barley (Hordeum vulgare L.) has been cultivated for almost 6000 years. Thus far, 150-year-old grains from historical collections have been used to investigate the distribution of barley diversity and how the species has spread across the region. Genetic studies of archaeobotanical material from agrarian sites could potentially clarify earlier migration patterns and cast further light on the origin of barley landraces. In this study, we aimed to evaluate different archaeological and historical materials with respect to DNA content, and to explore connections between Late Iron Age and medieval barley populations and historical samples of barley landraces in north-west Europe. The material analysed consisted of archaeological samples of charred barley grains from four sites in southern Finland, and historical material, with 33 samples obtained from two herbaria and the seed collections of the Swedish museum of cultural history.

The DNA concentrations obtained from charred archaeological barley remains were too low for successful KASP genotyping confirming previously reported difficulties in obtaining aDNA from charred remains. Historical samples from herbaria and seed collection confirmed previously shown strong genetic differentiation between two-row and six-row barley. Six-row barley accessions from northern and southern Finland tended to cluster apart, while no geographical structuring was observed among two-row barley. Genotyping of functional markers revealed that the majority of barley cultivated in Finland in the late nineteenth and early twentieth century was late-flowering under increasing day-length, supporting previous findings from northern European barley.     

Children’s participation in research on sensitive topics: addressing concerns of decision-makers

ABSTRACT

Although there is general agreement about children’s engagement in social research, some researchers continue to experience challenges when seeking approval and support for children’s participation from a range of adult stakeholders, particularly when the research involves a sensitive topic. These challenges may reflect different perspectives, conflicting interests, needs or expectations. This paper explores factors that influence the decision-making of key stakeholder groups, including Human Research Ethics Committees, parents and organisational representatives. Building on the kind of objective, rational reasoning that underpins much ethical decision-making, the findings, from interviews with 42 participants across stakeholder groups, draw attention to influential issues grounded in perceptions of: the institution and researcher undertaking the research; the project itself; children’s characteristics and contexts. Collectively, such issues point to the critically important role of mutually respectful relationships between researchers and stakeholders as the basis for designing and implementing ethical research that gives close attention to stakeholder concerns.     

‘We’re not very good at soccer’: gender,space and competence in a Victorian primary school

ABSTRACT

This paper draws on findings from a pilot project conducted at an inner city primary school in Melbourne, Australia. Inviting grade six girls and boys (aged eleven and twelve) to focus on spaces of their schoolground, we learned about the ways in which gender, age, ethnicity, language ability and sporting competence influenced active play and belonging. Informed by the understanding that schoolgrounds, gender and active play are socially constructed, and children are active agents in these constructions, the paper examines how girls and boys consider and negotiate spatial politics. The methods of participant-led photography, focus groups and thematic analysis, reveal how children understand gendered spatialities. A strong story emerged of girls’ experience of exclusion from active play spaces in particular, providing a perspective on the spatial and social performance of gender. The findings highlight the value of integrating a spatial analysis of schoolgrounds – and the gendered dynamics therein – for health, education and equity programmes.     

‘It’s fun in the legs’: children’s dwelling in garden trampolines

ABSTRACT

Physical activity is critical for children’s current and future health status. Understanding how children’s everyday outdoor environments encourage movement could help progress the health-environment debate. In response to this, and adopting a theoretical focus upon dwelling, skills and the haptic engagement, this qualitative case study explores 25 Danish 10–11-year-old children’s everyday use of garden trampolines. Three principal methods of data generation were employed in the fieldwork: photo-elicited interviews, group interviews and participant observation at children’s important outdoor places. Findings suggest that garden trampolines are important everyday outdoor places for children that – among other things – can spark a vigorous physical movement in abundantly meaningful and joyful ways. Further, findings indicate that trampolines are places of inexhaustible movement opportunities, which operate through haptic sensations, feelings of skilfulness and attunement, expansions of the range of motions available to the body, and interactions between children. Implications for future research and design are highlighted.
