The loss of a child and the desire to replace the loss is another important factor that is not acknowledged in all studies, with only one study stratifying analyses based on infant survival or death within the first year [ 16].
There are limitations to our study, particularly ascertainment and reporting biases, as acknowledged in previous studies of emerging infectious diseases (2, 3 ).
Although these approaches have been widely acknowledged in environmental studies they have not yet conquered the field of simulating environment-induced migration, which is likely related to the fact that simulating those processes is a rather new endeavour (McLeman 2013).
The association between objectively assessed environmental barriers and mortality has not been widely studied, even though the environmental implications for healthy aging have been acknowledged in several studies.
Considering whether the experiences of women are sufficiently acknowledged in disability studies, Susan Wendell points to masculinist influences on the field's standard model of disability (1996).
The potential of rangelands to store carbon in soils and vegetation has been acknowledged in many studies (e.g. IPCC 2007) and lies within the natural state of rangelands or rangelands moderately disturbed by grazing (Perez-Quezada et al. 2011).
This has been acknowledged in previous studies to be the result of primers designed to capture the largest eukaryotic diversity possible [3].
The context dependency of regulatory networks has been identified and acknowledged in many studies.
The importance of mobility in determining individual environmental exposures and in shaping the profile of the underlying population at risk has been acknowledged in many studies [ 2- 7].
