The road to excellence: deliberate practice and the development of expertise

The relative contribution of domain‐specific and non‐domain‐specific activities to the development of soccer expertise was examined using a retrospective cross‐sectional design. Elite and sub‐elite players aged between 9 and 18 years of age completed a participation history questionnaire under supervision. Weekly and accumulated hours spent in soccer team practice most consistently discriminated between skill levels across age cohorts. Elite players spent more time in decision‐making activities during team practice, possessed higher levels of motivation and had greater parental support. Maturational indices, time spent in playful activities, sporting diversity and time at which specialization occurred did not differentiate between groups. Engaging in activities deliberately designed to improve performance rather than mere experience within the domain or experience of related activities is likely to lead to elite status.

Primary physical education: a complex learning journey for children and teachers

Primary physical education (PPE) is increasingly being recognised for the role it can potentially play in setting a foundation for lifelong engagement in physical activity. However, the majority of the literature continues to focus on the negative features of the subject within the primary context. Whilst acknowledging the existence of these barriers, this paper sets out to take a proactive approach by presenting a conceptual framework for PPE that seeks to support a renewed and positive vision for the future. Based on ideas from complexity thinking, the framework represents a move beyond the more positivist and linear approaches that have long been reported to dominate practices in PPE and recognises learners as active agents engaged in a learning process that is collaborative, non-linear and uncertain. While acknowledging the contested nature of the complexity field, the paper explores how key principles, including self-organisation, emergence, similarity, diversity, connectedness, nestedness, ambiguous bounding, recursive elaboration and edge of chaos, offer a lens that views PPE as a complex system. With the children's learning positioned as the focus of PPE in the educational setting, the paper discusses how complexity principles interweave with the ecological components to help us better understand and more creatively engage with the complex nature of PPE developments. Specifically, these components are identified as PPE learning experiences and their associated pedagogy, teachers and their PPE professional learning and key environmental factors that include the physical environment and key stakeholders who influence developments across the different levels of the education system. The paper concludes by suggesting that this complexity-informed PPE framework represents an open invitation for the all those involved in PPE to engage in a collective process of exploration and negotiation to positively influence developments in PPE.     

Accessing participatory research impact and legacy: developing the evidence base for participatory approaches in health research

Action research has been characterised as systematic enquiry into practice, undertaken by those involved, with the aim changing and improving that practice: an approach designed to have impact. Whilst much has been written about the process and practice of ‘researching’, historically ‘impact’ has been somewhat taken for granted. In recent years, however, the impact of all forms of research has become the focus of interest with many funding bodies now demanding that researchers not only articulate the prospective impact of their work, but what kinds of evidence will be proffered to demonstrate that impact. This has raised questions for action researchers, not about whether their work has an impact, but what form that impact takes, how it is recognised and by whom. This paper focuses on difficulties researchers find in both articulating the impact of participatory research and demonstrating links between such forms of research and impact. We draw on discussions about the notion of impact with authors that have self-reported and published their work as participatory. These discussions revealed that not only were there difficulties in clarifying the participatory dimension of their research but that whilst authors were able to discuss particular impacts of their work, articulating and evidencing that impact was often absent from their published papers. This paper offers insights into some of issues and barriers those who undertake participatory research face in explicating, for the external audience (and indeed sometimes for ourselves), the impact of this action-based form of enquiry.     

Lessons for co-innovation in agricultural innovation systems: a multiple case study analysis and a conceptual model

Purpose: This paper highlights important lessons for co-innovation drawn from three ex-post case study innovation projects implemented within three sub-sectors of the primary industry sector in New Zealand.

Design/methodology/approach: The characteristics that fostered co-innovation in each innovation project case study were identified from semi-structured interviews conducted with key stakeholders in each project, iterative discussions to confirm the findings and secondary document analysis. Common themes from the three cases are examined in relation to innovation system structure and function analysis and agricultural innovation system (AIS) literature. This study builds on the literature attempting to overcome methodological challenges in the applied AIS research space.

Findings: The findings have implications for co-innovation in practice; that there needs to be network-level capability and legitimacy, an understanding of priorities between actors, and adequate resources, to ensure proposed outcomes are likely to be attained.

Practical implications: Practically, project leaders need to ensure they embed an appropriate mix of actors in the research program and they also need to create and encourage room for open and honest dialogue between these actors to develop a shared vision of the future.

Theoretical implications: A conceptual model is developed to highlight and simplify lessons that can inform future projects involving co-innovation approaches to create value in the primary industries and AIS more generally. This model is unique to the applied AIS research space and provides new insights on enhancing the potential value of a co-innovation approach.

Originality/value: The paper adds to current scholarly debates and provides insight to key actions stakeholders need to take to foster co-innovation processes for successful outcomes in extension.     

An interdisciplinary approach to environmental and sustainability education: developing geography students’ understandings of sustainable development using poetry

Education for sustainable development (ESD) persists as an important concept within international policy and yet, despite considerable debate, there remains a lack of consensus as to a pedagogy for ESD in schools. This paper presents findings from a study investigating how an interdisciplinary approach to ESD in England developed one class of 16- and 17-year-old geography students’ understandings of sustainability. The research used students’ drawings of sustainable cities alongside questionnaires and semi-structured interviews to explore their understanding of sustainable development within a constructivist, case study framework. The study found that the use of poetry within a geography lesson developed students’ appreciation of the social and economic dimensions of sustainability, although their focus persisted around the environmental. As such, it is argued that an interdisciplinary approach to ESD encourages students to engage more critically and affectively with the concept of sustainable development, thereby developing a more holistic appreciation of it.     

A review of interventions for adolescents with insomnia and the role of the educational and child psychologist: when sleep does not come easily

The role of an educational and child psychologist involves the promotion of mental health and wellbeing. While adolescents who have insomnia are usually referred to Primary Healthcare services, it might be argued that insomnia can be seen as a barometer of psychological wellbeing and should warrant a psychological intervention. A search of PSYCHINFO and Medline revealed that interventions carried out thus far with adolescents who have difficulty initiating and/or maintaining quality sleep include Sleep Hygiene and Sleep Education, Cognitive Behavioural and Multi Component interventions. In this review it will be posited that using multi-modal approaches which are tailored to specific needs may have the most positive outcomes in the treatment of insomnia, by helping adolescents to develop a sense of self-efficacy and emotional regulation in the context of family and peer support. Educational and child psychologists are ideally placed to offer this type of input to adolescents with insomnia.     

Do women with smaller breasts perform better in long-distance running?

Literature has established that a range of physiological, biomechanical, and training variables influence marathon performance. The influence of anthropometric characteristics has also received attention. However, despite major marathons exceeding 40,000 participants and approximately a third of these runners being female, no data exist on the influence of the breast on running performance. This cross-sectional study aimed to explore the impact of breast mass on marathon finish time. One hundred and sixty-eight of 321 female marathon runners contacted completed an on-line survey focusing on marathon performance during the 2012 London marathon. Participants were categorised as smaller (<500?g, 54%) or larger breasted (>500?g, 46%). Regression analysis identified that 24% of marathon performance variance could be explained by body mass index (BMI), but breast mass improved the model to explain 28% of performance variation. The model determined that for women with 32/34 or 36/38 underband each increase in cup size equates to a performance decrement of 4.6?min or 8.6 min, equivalent to 34.4?min difference between a woman with 36A compared to 36DD breast size. Larger breasted runners had greater BMIs, completed less marathons and had slower marathon finish times (316?±?48?min) compared to smaller breasted runners (281?±?51?min). Twenty-five per cent less larger breasted women finished in the fastest quartile. These results suggest that differences in breast mass are an important factor for female athletes and should be considered in future research in this area.
