Informal mealtime pedagogies: exploring the influence of family structure on young people's healthy eating dispositions
Families are increasingly recognised as informal sites of learning, especially with regard to healthy eating. Through the use of Bourdieu's conceptual tools, this paper explores the role of family meals within different family structures and the informal pedagogic encounters that take place. How they help to construct young people's healthy eating beliefs, values and dispositions, together with what influences their ability to conduct healthy lifestyle practices within different social and material conditions, is also considered. This study draws from semi-structured interviews with students (n =62) from three inner city comprehensive schools in the Midlands, UK, who were invited to interview with a friend from the same family structure. The interview protocol sought to uncover how often young people ate with their family and elicit their subjective views of family meals as a social context (pedagogical field) in which health messages were conveyed. Corresponding interview data were analysed using thematic analysis which revealed two main themes: (1) the importance of family meals as a pedagogic context for the (re)production of health-related beliefs, values and dispositions and (2) the influence of family structure on individual agency. The narratives illustrate the varying role of family meals for young people in different fields and suggest that family (as a primary field) with its particular practices can act as a site of informal pedagogy, but crucially, only for those whose social and material conditions allow. We should therefore not assume that family meals are 'normative' for all families and may serve different functions for different families. Hence, in a period of economic depression and prolonged austerity, encouraging family units of any structure to invest in family meals from an early age will help to enhance young people's healthy dispositions. © 2013 Copyright Taylor and Francis Group, LLC
The Plasmodium falciparum, Nima-related kinase Pfnek-4: a marker for asexual parasites committed to sexual differentiation
<b>Background</b>
Malaria parasites undergo, in the vertebrate host, a developmental switch from asexual replication to sexual differentiation leading to the formation of gametocytes, the only form able to survive in the mosquito vector. Regulation of the onset of the sexual phase remains largely unknown and represents an important gap in the understanding of the parasite's complex biology.
<b>Methods:</b>
The expression and function of the Nima-related kinase Pfnek-4 during the early sexual development of the human malaria parasite Plasmodium falciparum were investigated, using three types of transgenic Plasmodium falciparum 3D7 lines: (i) episomally expressing a Pfnek-4-GFP fusion protein under the control of its cognate pfnek-4 promoter; (ii) episomally expressing negative or positive selectable markers, yeast cytosine deaminase-uridyl phosphoribosyl transferase, or human dihydrofolate reductase, under the control of the pfnek-4 promoter; and (iii) lacking a functional pfnek-4 gene. Parasite transfectants were analysed by fluorescence microscopy and flow cytometry. In vitro growth rate and gametocyte formation were determined by Giemsa-stained blood smears.
<b>Results:</b>
The Pfnek-4-GFP protein was found to be expressed in stage II to V gametocytes and, unexpectedly, in a subset of asexual-stage parasites undergoing schizogony. Culture conditions stimulating gametocyte formation resulted in significant increase of this schizont subpopulation. Moreover, sorted asexual parasites expressing the Pfnek-4-GFP protein displayed elevated gametocyte formation when returned to in vitro culture in presence of fresh red blood cells, when compared to GFP- parasites from the same initial population. Negative selection of asexual parasites expressing pfnek-4 showed a marginal reduction in growth rate, whereas positive selection caused a marked reduction in parasitaemia, but was not sufficient to completely abolish proliferation. Pfnek-4- clones are not affected in their asexual growth and produced normal numbers of stage V gametocytes.
<b>Conclusions:</b>
The results indicate that Pfnek-4 is not strictly gametocyte-specific, and is expressed in a small subset of asexual parasites displaying high rate conversion to sexual development. Pfnek-4 is not required for erythrocytic schizogony and gametocytogenesis. This is the first study to report the use of a molecular marker for the sorting of sexually-committed schizont stage P. falciparum parasites, which opens the way to molecular characterization of this pre-differentiated subpopulation
Locating the place and meaning of physical activity in the lives of young people from low-income, lone-parent families
Background: In the United Kingdom (UK), it is predicted that economic cuts and a subsequent increase in child poverty will affect those already on the lowest incomes and, in particular, those living in lone-parent families. As a result, the informal pedagogic encounters within the family that contribute to the development of physical activity-related values, beliefs and dispositions from a very early age will be affected. Therefore, it is vital that we gain an understanding of the place and meaning of physical activity in the lives of young people, as well as the informal pedagogic practices and the socio-cultural forces that influence individual agency. Purpose: Based on Bourdieu's key concepts, this paper explores the interplay of structural conditions and personal agency with regard to physical activity in the lives of young people from low-income, lone-parent families. Methods: This study reports on the voices of 24 participants (aged 11–14) from low-income, lone-parent families in the West Midlands, UK. These participants were engaged in paired, semi-structured interviews to explore issues of personal agency by listening to how they reported on their present lives, past experiences and future possibilities with regard to physical activity. All corresponding interview data were analysed using analytical induction. Findings: This paper suggests that young people exhibited diminished desires to engage in activity due to structural constraints of time, parents' work commitments and a lack of transport that resulted in engagement in sedentary alternatives. Informal pedagogic practices within these families were restricted due to the associated structural conditions of living in a lone-parent family. As such, young people's choice to not seek out physical activities when at home reflected a ‘taste for necessity’ resulting from a lack of cultural and economic capital, placing restrictions on physical activity opportunities that stemmed from their family doxa. Conclusions: To succeed in fostering dispositions and opportunities to participate in physical activity, we must engage with young people from low-income, lone-parent families from an early age. Certainly though, further consideration of the informal pedagogic practices within, and the demands on, lone-parent families is required when designing any intervention or policy that seeks to enhance their current circumstances and provide opportunities for engagement in a variety of contexts
Sport and physical activity in the lives of looked-after children: a ‘hidden group’ in research, policy and practice
Looked-after children are arguably one of the most disadvantaged groups in society and constitute a ‘hidden group’ in relation to sport and physical activity research, policy and practice. Research on looked-after children has explored the views of caregivers, practitioners and policy-makers who have often been asked to speak for children on their behalf. Through the use of the mosaic approach and innovative participatory methods, including peer interviewing, the purpose of this paper was to provide an insight into a new area of research in the field of sport and physical activity. As such, it reports on initial findings from a wider project with looked-after children that explores their sport and physical activity experiences. Specifically, it asks the following: (1) What are the sport and physical activity experiences of looked-after children? (2) What meanings and values do looked-after children ascribe to their engagement in sport and physical activity? Findings from the voices of four male looked-after children highlight that these young people used sport as a means to an end; to spend time with friends and develop stocks of social capital. However, due to changes in placement, they also experienced disrupted patterns of engagement coupled with additional institutional constraints that shaped access to sporting activities
Co-producing strategies for enacting trauma-aware pedagogies with pre-service physical education teachers
Background:
In Physical Education (PE), trauma may manifest in a range of different actions/behaviours (e.g. small fouls escalating into physical conflict, students refusing to be part of a team, and struggling to adhere to the rules of the game). Without knowledge of the effects of trauma, teachers often defer to punitive responses, which exacerbate rather than mediate the needs of trauma-affected youth. It is therefore critical that prospective physical educators can enact trauma-aware practices to better support their learning and development.
Purpose:
The aim of this novel paper was to reflect on the principles underpinning trauma-aware pedagogies and, from this, co-create tangible strategies that could be employed by future PE teachers to better support all students, but especially those who have experienced trauma.
Methods:
We worked with three distinct groups of pre-service PE teachers(n= 22) from a range of different institutions, delivering a total of 12 hours of online workshops (2 × 2-hour sessions per group). The workshops were designed to support pre-service PE teachers in becoming trauma-aware and were grounded in the principles of trauma-aware pedagogies, namely: (1) ensuring safety and wellbeing, (2) establishing routines and structures, (3) developing and sustaining positive relationships that foster a sense of belonging, (4) facilitating and responding to youth voice and, (5) promoting strengths and self-belief. Through a range of academic content, individual activities and group tasks, participants were invited to consider, in conversation with us (as the workshop leaders) and each other, how these principles could be enacted in practice during various ‘PE moments’(e.g. transitions into PE, getting changed, responding to incidents). Audio recordings of the workshops were transcribed, and along with copies of the online ‘chats’, were thematically analysed.
Findings:
The workshops led to the co-creation of a host of tangible strategies–things that could be done to enact trauma-aware pedagogies in PE. While the strategies are noted here in relation to specific principles, we are not suggesting that these are in any way rigid categorisations. Rather, strategies are associated with principles reflecting how these were framed by pre-service teachers during the workshops. Each of the individual strategies is subsequently explored in relation to the relevant principle. For instance, strategies associated with the principle of ‘establishing routines and structures’ included: (1) being predictable, (2) ensuring consistent transitions within and between PE lessons, and (3) forewarning of changes.
Conclusions:
This novel paper provides a range of strategies that could be used by both future and current teachers to enact trauma-aware pedagogies in PE. We argue that these strategies are reflective of ‘good pedagogy’ more broadly–and would benefit all students – but especially those who have been impacted by trauma. However, there remains a need to consider the context of the school, the students, and broader cultures when implementing these within practice
Exploring pre-service physical education teachers' trauma-related learning experiences in schools
This paper explores pre-service physical education (PE) teachers' experiences of working with trauma-affected young people whilst on placement in schools. It involved an online professional learning programme which facilitated reflective discussions to explore their experiences. The pre-service teachers revealed that the school context influenced their trauma-related learning, which took place across multiple sites throughout the school, with both teachers and pupils. These findings evidence the need to support pre-service PE teachers’ school-based learning, encouraging them to explore the broader context of the school, seek supportive relationships and co-develop strategies to create positive and safe learning environments
Litter quality and its response to water level drawdown in boreal peatlands at plant species and community level
Changes in the structure of plant communities may have much more impact on ecosystem carbon (C) cycling than any phenotypic responses to environmental changes. We studied these impacts via the response of plant litter quality, at the level of species and community, to persistent water-level (WL) drawdown in peatlands. We studied three sites with different nutrient regimes, and water-level manipulations at two time scales. The parameters used to characterize litter quality included extractable substances, cellulose, holocellulose, composition of hemicellulose (neutral sugars, uronic acids), Klason lignin, CuO oxidation phenolic products, and concentrations of C and several nutrients. The litters formed four chemically distinct groups: non-graminoid foliar litters, graminoids, mosses and woody litters. Direct effects of WL drawdown on litter quality at the species level were overruled by indirect effects via changes in litter type composition. The pristine conditions were characterized by Sphagnum moss and graminoid litters. Short-term (years) responses of the litter inputs to WL drawdown were small. In longterm (decades), total litter inputs increased, due to increased tree litter inputs. Simultaneously, the litter type composition and its chemical quality at the community level greatly changed. The changes that we documented will strongly affect soil properties and C cycle of peatlands.Peer reviewe
Can’t pay, can’t play? Talent lead’s perspectives on the financial constraints experienced by athletes on the England Talent Pathway
© 2017 European Council for High Ability This study explored the extent of financial constraints experienced by athletes on the England Talent Pathway, as perceived by talent leads from various sports. Using a mixed-methods approach, 34 participants completed online surveys with 26 follow-up interviews. Findings showed the prevalence of financial constraints on individuals within the system, with three emerging themes: costs; demands on athletes; and potential funding support. “Pinch points”, causing the greatest severity of financial constraint, emerged further along the pathway and there were infrequent examples of mechanisms to identify talented athletes experiencing financial hardship. A means-tested system, premised on the demonstration of potential, is suggested by talent leads as a way of providing funding for athletes to ameliorate financial constraints in the future

Implementing physically active learning: Future directions for research, policy, and practice
Objective
Identify co-produced multi-stakeholder perspectives important for successful widespread physically active learning (PAL) adoption and implementation.
Method
A total of 35 stakeholders (policy makers, n = 9; commercial education sector, n = 8; teachers, n = 3; researchers, n = 15) attended a design thinking PAL workshop. Participants formed 5 multi-disciplinary groups with at least 1 representative from each stakeholder group. Each group, facilitated by a researcher, undertook 2 tasks: (1) using Post-it Notes, the following question was answered: within the school day, what are the opportunities for learning combined with movement? and (2) structured as a washing-line task, the following question was answered: how can we establish PAL as the norm? All discussions were audio-recorded and transcribed. Inductive analyses were conducted by 4 authors. After the analyses were complete, the main themes and subthemes were assigned to 4 predetermined categories: (1) PAL design and implementation, (2) priorities for practice, (3) priorities for policy, and (4) priorities for research.
Results
The following were the main themes for PAL implementation: opportunities for PAL within the school day, delivery environments, learning approaches, and the intensity of PAL. The main themes for the priorities for practice included teacher confidence and competence, resources to support delivery, and community of practice. The main themes for the policy for priorities included self-governance, the Office for Standards in Education, Children's Services and Skill, policy investment in initial teacher training, and curriculum reform. The main themes for the research priorities included establishing a strong evidence base, school-based PAL implementation, and a whole-systems approach.
Conclusion
The present study is the first to identify PAL implementation factors using a combined multi-stakeholder perspective. To achieve wider PAL adoption and implementation, future interventions should be evidence based and address implementation factors at the classroom level (e.g., approaches and delivery environments), school level (e.g., communities of practice), and policy level (e.g., initial teacher training)
