Survival benefits in mimicry: a quantitative framework

Mimicry is a resemblance between species that benefits at least one of the species. It is a ubiquitous evolutionary phenomenon particularly common among prey species, in which case the advantage involves better protection from predation. We formulate a mathematical description of mimicry among prey species, to investigate benefits and disadvantages of mimicry. The basic setup involves differential equations for quantities representing predator behavior, namely, the probabilities for attacking prey at the next encounter. Using this framework, we present new quantitative results, and also provide a unified description of a significant fraction of the quantitative mimicry literature. The new results include `temporary' mutualism between prey species, and an optimal density at which the survival benefit is greatest for the mimic. The formalism leads naturally to extensions in several directions, such as the evolution of mimicry, the interplay of mimicry with population dynamics, etc. We demonstrate this extensibility by presenting some explorations on spatiotemporal pattern dynamics.Comment: 9 pages, 7 figure

Social Media And Health: Implications For Primary Health Care Providers

This report is the second deliverable of the ?Digital Inclusion and Social Knowledge Media for Health: Frameworks and Roadmaps? project. The first discussed the concept of social and digital exclusion whilst this report focuses on the emerging phenomenon of social media. The report outlines current knowledge on the users and usages of social media for health and goes on to discuss social media in the context of a continuing focus (ref. D1.1) on the areas of mental health, smoking cessation and teenage lifestyles. The report concludes with an outline of an approach to a ?social media strategy? and with suggestions for directions for future research

An Evidence-Based Approach To Digital Inclusion for Health

This report is the first deliverable of the ?Digital Inclusion and Social Knowledge Media for Health: Frameworks and Roadmaps? project. It discusses the concept of social and digital exclusion and suggests that a focus on the digital mediation of social processes may provide more purchase for public service providers. This focus leads to the consideration of the way in which digital services might support a range of health-related factors which are both directly and indirectly linked to specific health outcomes. The report discusses some examples in the light of a consideration of the specific (and spatial) health needs and priorities of Solihull Care Trust. The report concludes with suggestions for directions for future research and development

Energy Market Integration in East Asia: A Regional Public Goods Approach

This study applies a regional public goods approach to the study of energy market integration (EMI) in East Asia, with a view to clarifying the outlook for such integration and the likely obstacles to be encountered. In addition to drawing on theoretical ideas relating to regional public goods, the paper will also draw on the experience of the European Union in its attempts to develop a single energy market. The study shows that many services are needed in order to develop and sustain a regional integrated energy market and that some of these services have characteristics of regional public goods, though some may also be trans-regional or global in nature as well. The study recommends that: EMI in East Asia should be pursued in an incremental manner and mainly at a sub-regional scale; and the specific steps taken towards EMI should be chosen on the basis of their likely positive economic impacts and their likely ease of delivery.
