the rapid growth of population in the third world countries specially in recent decades has posed an important social problem. there have been some attempts to propose solutions for this problem by scientists from various disciplines. however, it seems that an integrated approach calling for collaboration of various efforts can be more fruitful. in this work, we study the relation of women fert...

abstract nowadays, fuzzy technique is used to prepare the map in different sciences, extensively. with due attention to important role of soil fertility in modern agriculture, the preparation of soil fertility map seems to be necessary to plan for appropriate using of fertilizers for crops. this study was conducted to prepare a distinct map for evaluating soil fertility according to soil availa...

The Multicriteria Decision Analysis (MCDA) and Geographical Information Systems (GIS) are used to provide more accurate decisions to the decision makers in order to evaluate the effective factors in the natural science. One of the popular algorithm of multicriteria analysis is Ordered Weighted Averaging (OWA). The OWA procedure depends on some parameters, which can be 15 specified by means of f...

Background: infant mortality rate is one of the main health indicators for assessing the health system’s performance over the world. We aim to examine the socioeconomic and health system factors affect infant mortality in OPEC from 2004 to 2013. Methods: was used to examine the effects of some of the key explanatory factors (total fertility rate per women, GDP per capita (current US$), public h...

Conventional theories have little to say about the level at which fertility will stabilize at the end of the demographic transition, although it is often assumed that replacement fertility of about 2.1 births per woman will prevail in the long run. However, fertility has dropped below the replacement level in virtually every population that has moved through the transition. If future fertility ...

This paper questions the proposition that fertility was invariably high among populations before the fertility transition. By examining factors affecting pre-transition fertility based on the evidence from Japan and India in the pre-World War II period, together with that from England and Germany in the traditional period, it suggests that in most historical populations fertility was below the ...

BACKGROUND While recent studies have indicated that fertility has remained high in Uganda, no systematic attempt has been made to identify the factors responsible for this persistent trend and to quantify these factors. This paper uses the Uganda Demographic and Health Surveys (UDHS) of 2006 and 2011, to examine the contribution contraceptive use, marriage and postpartum infecundability on one ...
