Public Health and Well-being Innovation in the Natural Environment Sector: Lessons from the UK and Finland
Thirty-one ethnographic interviews were conducted with health and well-being sector businesses to examine the dynamics of innovation in the UK (Cornwall) and across Finland. The Nordic countries are at the leading edge of these types of public health nature-based interventions, consequently, Finland was chosen as a comparator to the UK. We found that the construction of natural environment based services for health and well-being follows a five-step model: (1) Services are specifically designed for individuals’ needs; (2) These services are based around routine behaviours of that individual and their personal and social habits; (3) This creates a process of normalisation that relates to former states of health prior to being ill; (4) These routines generally function at a habitual level if they are to be of use on a daily basis (we are not conscious of all of our actions all the time); and (5) nature is used to embed these new routines because it allows access to the latent forms of thought, not ones that require direct conscious learning. We found this emergent process closely resembles Pierre Bourdieu’s concept of habitus. A number of health and well-being businesses have moved towards mixed models of service provision– combining profit-making activities in the tourism and leisure markets with care services to create a sustainable service model in response to increasing pressures on funding sources. However, more still needs to be done in terms of training for public health and well-being businesses if this service model is to become financially sustainable for all
Unreliability of mutual information as a measure for variations in total correlations
Abstract
Correlations disguised in various forms underlie a host of important phenomena in classical and quantum systems, such as information and energy exchanges. The quantum mutual information and the norm of the correlation matrix are both considered as proper measures of total correlations. We demonstrate that, when applied to the same system, these two measures can actually show significantly different behavior except at least in two limiting cases: when there are no correlations and when there is maximal quantum entanglement. We further quantify the discrepancy by providing analytic formulas for time derivatives of the measures for an interacting bipartite system evolving unitarily. We argue that to properly account for correlations one should consider the full information provided by the correlation matrix (and reduced states of the subsystems). Scalar quantities such as the norm of the correlation matrix or the quantum mutual information can only capture a part of the complex features of correlations. As a concrete example, we show that in describing heat exchange associated with correlations neither of these quantities can fully capture the underlying physics. As a byproduct, we also prove an area law for quantum mutual information in systems with local and short-range interactions, without need to assume Markovianity or final thermal equilibrium
