Critical phenomena in globally coupled excitable elements
Critical phenomena in globally coupled excitable elements are studied by
focusing on a saddle-node bifurcation at the collective level. Critical
exponents that characterize divergent fluctuations of interspike intervals near
the bifurcation are calculated theoretically. The calculated values appear to
be in good agreement with those determined by numerical experiments. The
relevance of our results to jamming transitions is also mentioned.Comment: 4 pages, 3 figure
The Child Feeding Guide:A digital health intervention for reducing controlling child feeding practices and maternal anxiety over time
Fussy eating and food refusal are common in young children. These behaviours can contribute to anxiety or concern in parents and caregivers, who have called for credible support to help them navigate the challenges of feeding young children. Given recent increases in technology, and use of the Internet as a trusted source of parenting support, the Child Feeding Guide digital health intervention was created to provide evidence-based support to parents and caregivers to help them to feed children and establish healthy eating habits from the early years. An evaluation was conducted with 25 mothers (with a child aged 6 months to 4 years) who used the Child Feeding Guide website/app over 4 weeks. Mothers provided information about their feeding practices and anxiety levels at baseline, and again 4 weeks later, and answered questions regarding the acceptability and use of the digital support resource. Significant decreases were seen in maternal anxiety and in maternal use of pressure to eat and restriction of food from children for weight reasons. Mothers reported that the Child Feeding Guide was easy to use, that they valued its credibility and reassurances, and that its content helped them to better understand their child’s eating behaviour. These promising findings suggest that naturalistic use of a digital health intervention could contribute to reductions in mothers’ use of controlling feeding practices and levels of anxiety. Such findings are important for supporting the development of healthy eating habits in young children and are likely to be relevant to health and childcare professionals
Globalization & the Law: An Introduction
The focus of this special issue of the Alberta Law Review is globalization and the law. The purpose of this special issue is to look at ways that law is participating, and can participate, in the process of globalization. Given the social and political regulatory power of law- both domestic and international - there is no doubt that law can and should have a lot to say about how the process of globalization develops
Bayes linear kinematics in the analysis of failure rates and failure time distributions
Collections of related Poisson or binomial counts arise, for example, from a number of different failures in similar machines or neighbouring time periods. A conventional Bayesian analysis requires a rather indirect prior specification and intensive numerical methods for posterior evaluations. An alternative approach using Bayes linear kinematics in which simple conjugate specifications for individual counts are linked through a Bayes linear belief structure is presented. Intensive numerical methods are not required. The use of transformations of the binomial and Poisson parameters is proposed. The approach is illustrated in two examples, one involving a Poisson count of failures, the other involving a binomial count in an analysis of failure times

Local structural studies of BaKFeAs using atomic pair distribution function analysis
Systematic local structural studies of BaKFeAs system are
undertaken at room temperature using atomic pair distribution function (PDF)
analysis. The local structure of the BaKFeAs is found to be
well described by the long-range structure extracted from the diffraction
experiments, but with anisotropic atomic vibrations of the constituent atoms
( = ). The crystal unit cell parameters, the
FeAs tetrahedral angle and the pnictogen height above the Fe-plane are seen
to show systematic evolution with K doping, underlining the importance of the
structural changes, in addition to the charge doping, in determining the
properties of BaKFeAs
