“…Despite evidence that rates are plateauing, over 30 % of children remain overweight or obese in the USA and several other developed countries (6) . To reverse this disturbing trend, Healthy People 2020 objectives include increasing the variety and contribution of fruit and vegetables and reducing the consumption of energy from solid fats and added sugars in the population aged 2 years and older (7) . Schools have been identified as a particularly relevant context for nutrition education due to opportunities to integrate nutritional information into existing curricula and the opportunity to reach a large number of children (8)(9)(10)(11)(12)(13)(14)(15) .…”

Objective: The current study evaluated the overall public health impact of the 'Shaping Up My Choices' (SMC) programme, a 10-week school-based nutrition education curriculum developed for third-grade students, using the RE-AIM (Reach, Efficacy, Adoption, Implementation, Maintenance) framework. Design: Randomized controlled trial to evaluate the programme and secondary analysis of archival data to describe dissemination. Data were collected from programme records, teacher surveys and student pre-, post-and 3-month follow-up surveys. Setting: Public elementary schools in California. Subjects: An evaluation sample (938 students and nineteen teachers) and a dissemination sample (195 245 students and 7359 teachers). Results: In the evaluation sample, differences between the control and intervention groups were observed for nutrition knowledge, self-efficacy, outcome expectancies, and intakes of vegetables, fruit (girls only), soda, and low-nutrient high-energy foods from pre-to post-survey. Group differences in change in knowledge, outcome expectancies and vegetable intake were sustained through the 3-month follow-up (efficacy). One hundred per cent of intervention teachers in the evaluation sample implemented all of the lessons (implementation). The dissemination sample represented 42 % of third-grade students (reach) and 39 % of third-grade classrooms in public elementary schools in California during 2010-2011 (adoption). Thirty-seven per cent of third-grade teachers in the dissemination sample reordered SMC materials during the subsequent school year (2011-2012; maintenance). Conclusions: The SMC programme demonstrates the potential for moderate to high public health impact.

“…Both strategies are based on Bayesian theory, and approximation is also their main approach for solving the nonlinear filtering problem [31]. However, the perspectives of these two strategies are different, which results in different characteristics.…”

“…However, the model used to improve the proposal distribution must be based on some known noise model (such as the Gaussian model in EPF and Gaussian mixture model in UPF), which cannot fully solve the impoverishment problem [49]. The resampling step might alleviate the sample degeneracy, accompanied by the introduction of the resampling error [31]. The main problem of the second strategy is that the particle utilization efficiency is not high, which affects the effect and efficiency of the filtering [40].…”

Two-Dimensional Monte Carlo Filter for a Non-Gaussian Environment

In a non-Gaussian environment, the accuracy of a Kalman filter might be reduced. In this paper, a two- dimensional Monte Carlo Filter is proposed to overcome the challenge of the non-Gaussian environment for filtering. The two-dimensional Monte Carlo (TMC) method is first proposed to improve the efficacy of the sampling. Then, the TMC filter (TMCF) algorithm is proposed to solve the non-Gaussian filter problem based on the TMC. In the TMCF, particles are deployed in the confidence interval uniformly in terms of the sampling interval, and their weights are calculated based on Bayesian inference. Then, the posterior distribution is described more accurately with less particles and their weights. Different from the PF, the TMCF completes the transfer of the distribution using a series of calculations of weights and uses particles to occupy the state space in the confidence interval. Numerical simulations demonstrated that, the accuracy of the TMCF approximates the Kalman filter (KF) (the error is about 10−6) in a two-dimensional linear/ Gaussian environment. In a two-dimensional linear/non-Gaussian system, the accuracy of the TMCF is improved by 0.01, and the computation time reduced to 0.067 s from 0.20 s, compared with the particle filter.
