This study provides a framework for quantifying demand for family planning and using a proximate determinates model of fertility to evaluate the potential effects of various family planning intervention scenarios in a low-resourced environment.
Using a proximate determinates model of fertility, we predicted that modest increases in contraceptive prevalence and extended periods of breastfeeding could meet women's demand for family planning by reducing the TFR to 6 or fewer children per woman, while also curbing population growth and preventing further pressure on the environment.
Stover's proximate determinants model also includes a potential fertility (PF) term equal to 21 which is the theoretical maximum number of children a fecund woman could physically bear if she remained sexually active the entire time between ages 15 and 49 with no constraints on her fertility.
There are many kinds of models, requiring different methods of design and testing, varying from game theoretic and other ultimate models (such as those discussed above by Ay et al. (2007) and Wilson et al. (2013)), to proximate physical models (Webb 2001) and visual depictions (visual diagrammatic models will be discussed in the next section, question 2).
Do you think that young authors now have fewer proximate role models than you did in the sixties and seventies?
Using the proximate determinants framework, we modeled Idjwi's TFR to be 9.86, which is greater than TFR measured by our survey (8.3).
Because the scheme is local, there is no a priori assumption that the whole contours comply with a certain mathematical description: we only assume that the contour is smooth between two proximate primitives, and model this using Hermite interpolation.
This proximate architecture framework can be utilized for modelling behavioural challenges in complex environments, for example how animals make behavioural decisions based on multiple sources of information, or adapt to changing environments.
This work proposes new organismal and proximate level conceptual models for these phenomena.
Modelling proximate determinates of fertility, we evaluated how the introduction of contraceptives and/or extended periods of breastfeeding could reduce the TFR.
