However, this definition is ambiguous, and usually the ratio is too large to rigorously meet the effective medium theory.
Taking advantage of smallness of the plate thickness and heterogeneity, we use the variational asymptotic method to rigorously construct an effective plate model unifying a homogenization process and a dimensional reduction process.
p2P builds collaborations and partnerships between researchers, educators, commercial game developers, and community based organizations with the goal of developing and rigorously testing innovative, effective, and targeted game interventions for risk reduction and prevention in youth and young adults.
Reducing the incidence of shunt infection requires a number of measures before, during and after surgery [ 7, 10], and applying these measures rigorously has proved effective [ 52].
Overall, there is still a considerable lack of understanding of causal mechanisms underlying suicidal thoughts and behaviours and a paucity of effective, rigorously evaluated treatment and prevention strategies for suicide [ 4- 7].
The lack of evidence on SRH interventions in humanitarian contexts suggests weaknesses in investigating and rigorously documenting the most effective and cost-effective ways of delivering SRH services and a reliance on the status quo.
Those living in the model villages have rigorously adopted simple but effective sanitation and hygiene practices, like using clean water jugs for hand washing, carefully storing drinking water, harvesting rainwater, and building wooden racks for drying food utensils.
First, we need to build a better understanding of what makes active-learning exercises effective by rigorously exploring which elements are necessary and sufficient to improve learning (e.g., see Crouch et al., 2004; Smith et al., 2009, 2011; Perez et al., 2010).
A method of teaching fifth-grade math that has been rigorously shown to be highly effective for the students and teachers in one school district may well not work for the students and teachers in another.
While the production of educational studies whose aim is to document problems with science teacher knowledge and acceptance levels continues unabated, remarkably less work has been devoted to addressing the problem, or rigorously documenting the features of effective intervention programs.
