Analysis of the Non-singular Wyman-Schwarzschild Metric
The analog of the Schwarzschild metric is explored in the context of
Non-Singular Gravity. Analytic results are developed describing redshifts,
curvatures and topological features of the spacetime. All curvatures and
redshifts are finite so there are no Black Holes, no singularities and no
Hawking radiation.Comment: 14 pages, RevTeX, 6 Figures available on request, UTPT-94-1
Is the impact of social distancing on coronavirus growth rates effective across different settings? A non-parametric and local regression approach to test and compare the‘doubling rate
Epidemiologists use mathematical models to predict epidemic trends, and these results are inherently uncertain when parameters are unknown or changing. In other contexts, such as climate, modellers use multi-model ensembles to inform their decision-making: when forecasts align, modellers can be more certain. This paper looks at a sub-set of alternative epidemiological models that focus on the ‘doubling rate’, and it cautions against relying on the method proposed in (Pike & Saini, 2020) which relies on the data for China to calculate future trajectories. Such approaches are subject to overfitting, a common problem in financial and economic modelling. This paper finds, surprisingly, that the data for China are hyper-exponential, not exponential. Instead, this paper proposes using non-parametric methods, and local regression methods, to support epidemiologists and policymakers in assessing the relative effectiveness of social distancing across multiple settings.

Minimal Faithful Permutation Degrees for Irreducible Coxeter Groups and Binary Polyhedral Groups
In this article we calculate the minimal faithful permutation degree for all
of the irreducible Coxeter groups. We also exhibit new examples of finite
groups that possess a quotient whose minimal degree is strictly greater than
that of the group.Comment: 22 page
Embedding QR codes in the Bournemouth University print collection
During the 2011/12 academic year, Library and Learning Support (LLS) at BU have been working on a project to embed QR codes within the library print collection to highlight available e-books from heavily used areas of the shelves
Schools, communities and social capital: building blocks in the 'Big Society' (Research associate full report)
"This study looked at how effective schools engage with their communities. Its aim was to identify key
mechanisms that promoted community engagement. It also sought to determine the impact this had on the
amount and nature of social capital available to pupils, parents and the wider community. Effective schools
were found to generate significant amounts of social capital within their institutions as demonstrated by the
degree of trust, reciprocity, civic engagement and social cohesion. Pupil voice was a powerful mechanism in
developing a sense of control and self-efficacy. Recently created posts such as family workers, therapists and
social work placements extended much of this impact into the family.
Schools that went further to promote social capital in the neighbourhood were those with a more
aspirational vision that went beyond simply engaging the community to aid school improvement. They
viewed community empowerment as key to the success of their pupils and families within the wider social
context. They encouraged community leadership and decision-making, often through informal learning
approaches, and truly became ‘hubs of the community’, facilitating community development and promoting
community cohesion. The findings suggest that a more reciprocal view is needed of the relationship between
school and community and that schools could play a central role in creating the ‘Big Society’.
Object lessons : a learning object approach to e-learning for social work education
Learning objects are bite-sized digital learning resources designed to tackle the e-learning adoption problem by virtue of their scale, adaptability, and interoperability. The learning object approach advocates the creation of small e-learning resources rather than whole courses: resources that can be mixed and matched; used in a traditional or online learning environment; and adapted for reuse in other discipline areas and in other countries. Storing learning objects within a subject specific digital repository to enable search, discovery, sharing and use adds considerable value to the model. This paper explores the rationale for a learning object approach to e-learning and reflects on early experiences in developing a national learning object repository for social work education in Scotland
