Promising approaches to the promotion of healthier eating among children in primary school settings include the opportunity to practise practical cooking and growing, promoting the take up of healthier school meals and nutritional education. However, less is known about the potential for strategies that integrate approaches through a focus on food sustainability issues--such as the promotion of awareness about local, seasonal, organic, fair trade and higher animal welfare foods. This paper presents an evaluation of the Food for Life Partnership, a multi-component programme that sought to address both the health and sustainability aspects of food. The study consisted of a two-stage cross-sectional survey of Years 5 and 6 students (ages 9-11) in 30 primary schools at enrolment and after 18-24 months, combined with an analysis of programme delivery. Higher self-reported fruit and vegetable consumption in the second stage survey was associated with a range of indicators of school participation in the programme. These included the reform of school meal procurement and preparation; experiential food growing, cooking and farm-based education and improved opportunities for stakeholder engagement. The study therefore develops a case for multilevel programmes that incorporate sustainability issues alongside experiential food education in primary school settings.

AbstractPurpose -Health promotion programmes are widely held to be more effective when the subjects of them actively participate in the process of change. The purpose of this paper is to report on an evaluation of the Food for Life Partnership programme, a multi-level initiative in England promoting healthier nutrition and food sustainability awareness for students and their families through involvement in cooking, growing, farm visits and School Nutrition Action Groups (SNAGs). Design/methodology/approach -The study adopted a mixed methods approach, drawing upon quantitative and qualitative data sources. The data sources included quantitative data on school level programme related activities, qualitative data collected through focus groups with children and reports from teachers and other staff involved in the delivery of the programme. Findings -The paper concludes that the pivotal role of SNAGs in catalysing and embracing a whole school approach must be seen as an important mechanism for any health promotion in complex school environments. Originality/value -This was a national evaluation of a unique school food project aiming to transform food culture in primary and secondary schools. The findings highlight the importance of a whole school approach to public health initiatives and the centrality of pupil participation in the success and sustainability of such interventions.
We have studied the effects of viscosogenic agents, sucrose and ficoll, on (1) the hydrolysis of adenosine and of 6-methoxypurine riboside catalyzed by adenosine deaminase and (2) the rates of association and dissociation of ground-state and transition-state analogue inhibitors. For adenosine, Vmax/Km is found to be inversely proportional to the relative viscosity with sucrose, an agent affecting the microscopic viscosity, while no effect is found with ficoll, an agent affecting the macroscopic viscosity. Viscosogenic agents have no effect on the kinetic constants for 6-methoxypurine riboside. Thus, the bimolecular rate constant, Vmax/Km = 11.2 +/- 0.8 microM-1 s-1, for the reaction with adenosine is found to be at the encounter-controlled limit while that for the reaction with the poor substrate 6-methoxypurine riboside, 0.040 +/- 0.004 microM-1 s-1, is limited by some other process. Viscosity-dependent processes do not make a significant (less than 10%) contribution to Vmax. The dissociation constants for inhibitors are unaffected by viscosity. The ground-state analogue inhibitor purine riboside appears to bind at a rate comparable to that of adenosine. However, the slower rates of association (0.16-2.5 microM-1 s-1) and dissociation (5 X 10(-6) to 12 s-1) of transition-state analogue inhibitors are affected by the viscosity of the medium to approximately the same extent as the encounter-controlled rates of association and dissociation of adenosine.(ABSTRACT TRUNCATED AT 250 WORDS)
Pro- and anti-vaccination users use social media outlets, such as Twitter, to join conversations about vaccines, disseminate information or misinformation about immunization, and advocate in favour or against vaccinations. These users not only share textual content, but also images to emphasise their messages and influence their audiences. Though previous studies investigated the content of vaccine images, there is little research on how these visuals are distributed in digital environments. Therefore, this study explored how images related to vaccination are shared on Twitter to gain insight into the communities and networks formed around their dissemination. Moreover, this research also investigated who influences the distribution of vaccine images, and could be potential gatekeepers of vaccination information. We conducted a social network analysis on samples of tweets with images collected in June, September and October 2016. In each dataset, pro- and anti-vaccination users formed two polarised networks that hardly interacted with each other, and disseminated images among their members differently. The anti-vaccination users frequently retweeted each other, strengthening their relationships, making the information redundant within their community, and confirming their beliefs against immunisation. The pro-vaccine users, instead, formed a fragmented network, with loose but strategic connections that facilitated networking and the distribution of new vaccine information. Moreover, while the pro-vaccine gatekeepers were non-governmental organisations or health professionals, the anti-vaccine ones were activists and/or parents. Activists and parents could potentially be considered as alternative but trustworthy sources of information enabling them to disseminate misinformation about vaccinations.
