Control and choice in English prisons: developing health-promoting prisons.

The 'health-promoting prison' has been informed by a broader settings-based philosophy to health promotion which conceptualizes health as the responsibility for all social settings. Though in its relative infancy, the notion of a health-promoting prison has gained political backing from international organizations like the World Health Organization, but the implementation of the policy rhetoric has not translated across all prison environments. The aim of this paper is to consider how key elements of health promotion discourse-choice, control and implicitly, empowerment-can apply in the context of imprisonment. These concepts were examined in three category-C (secure) prisons in England, through interviews with 36 male prisoners and 19 prison staff conducted by the first author. Analysis showed that prisoners negotiated the norms, structures and strictures of prison life by both relinquishing control and also by taking control, showing resistance and exercising some element of choice. The paradox is that, as most prisoners are expected to be released at some point they need to exercise some agency, control and choice, but these learning experiences may be constrained whilst 'inside'. The paper argues that if a settings approach in prison is truly to move forward, both conceptually and practically, then health promoters should seek to embed the key values of health promotion within the prison setting

A discrete slug population model determined by egg production

Slugs are significant pests in agriculture (as well as a nuisance to gardeners), and it is therefore important to understand their population dynamics for the construction of efficient and effective control measures. Differential equation models of slug populations require the inclusion of large (variable) temporal delays, and strong seasonal forcing results in a non-autonomous system. This renders such models open to only a limited amount of rigorous analysis. In this paper, we derive a novel batch model based purely upon the quantity of eggs produced at different times of the year. This model is open to considerable reduction; from the resulting two variable discrete-time system it is possible to reconstruct the dynamics of the full population across the year and give conditions for extinction or global stability and persistence. Furthermore, the steady state temporal population distribution displays qualitatively different behavior with only small changes in the survival probability of slugs. The model demonstrates how small variations in the favorability of different years may result in widely different slug population fluctuations between consecutive years, and is in good agreement with field data

Improving health and well-being through community health champions: a thematic evaluation of a programme in Yorkshire and Humber.

AIMS: The contribution that lay people can make to the public health agenda is being increasingly recognised in research and policy literature. This paper examines the role of lay workers (referred to as 'community health champions') involved in community projects delivered by Altogether Better across Yorkshire and Humber. The aim of the paper is to describe key features of the community health champion approach and to examine the evidence that this type of intervention can have an impact on health. METHODS: A qualitative approach was taken to the evaluation, with two strands to gathering evidence: interviews conducted with different stakeholder groups including project leads, key partners from community and statutory sectors and community workers, plus two participatory workshops to gather the views of community health champions. Seven projects (from a possible 12) were identified to be involved in the evaluation. Those projects that allowed the evaluation team to explore fully the champion role (training, infrastructure, etc.) and how that works in practice as a mechanism for empowerment were selected. In total, 29 semi-structured interviews were conducted with project staff and partners, and 30 champions, varying in terms of age, gender, ethnicity and disability, took part in the workshops. RESULTS: Becoming a community health champion has health benefits such as increased self-esteem and confidence and improved well-being. For some champions, this was the start of a journey to other opportunities such as education or paid employment. There were many examples of the influence of champions extending to the wider community of family, friends and neighbours, including helping to support people to take part in community life. Champions recognised the value of connecting people through social networks, group activities, and linking people into services and the impact that that had on health and well-being. Project staff and partners also recognised that champions were promoting social cohesiveness and helping to integrate people into their community. CONCLUSIONS: The recent public health White Paper suggested that the Altogether Better programme is improving individual and community health as well as increasing social capital, voluntary activity and wider civic participation. This evaluation supports this statement and suggests that the community health champion role can be a catalyst for change for both individuals and communities
