In our previous study, focusing on a ranking determination, we developed two ranking models. The foundation of these ranking models is derived from either one of the two ranking methods, denoted by Ranking (I) and Ranking (II), that were proposed in our previous papers. The purpose of this paper is to analyze the mathematical structure in the process of generating Ranking (I) and Ranking (II) i...
The global population is at a turning point. At the end of 2004, the majority of the world’s population is believed to live in countries or regions below-replacement fertility, and the earlier distinct fertility regimes, ‘developed’ and ‘developing’, are increasingly disappearing in global comparisons of fertility levels (Wilson 2001, 2004). Several aspects of this convergence towards low ferti...
Many scholars have offered structural and ideational explanations for the fertility changes occurring around the world. This paper focuses on the influence of developmental idealism-a schema or set of beliefs endorsing development, fertility change, and causal connections between development and fertility. Developmental idealism is argued to be an important force affecting both population polic...
Studies of the causes of fertility levels and their changes often seek to measure directly the impact of socioeconomic factors on fertility. Such procedures have a broad appeal to policymakers, offering as they do to pinpoint mechanisms susceptible to manipulation by official policy. Despite this appeal, such approaches are considerably more problematical in their application. Not infrequently,...
data envelopment analysis (dea) technique now widely use for efficiency evaluation of a set of decision making units (dmus). as regards of the necessity for ranking efficient units different dea models presented each of which has advantages and rank efficient units from special aspects. note that all the existing ranking models have disadvantages, as well and there is not a model in which all t...
BACKGROUND Research on fertility differentials between eastern and western Germany after German reunification in 1990 has focused on the fertility of women. Trends in the fertility of men are rarely studied due to data constraints and methodological challenges. OBJECTIVE This paper aims to close this gap by analyzing fertility differentials between eastern and western German males over the peri...
INTRODUCTION Fertility counselling for young women newly diagnosed with cancer is an important field of preconceptional counselling. This qualitative, small-scale study explored how young women newly diagnosed with cancer experienced specialized fertility preservation counselling and treatment in the public Danish health care system. METHODS Semi-structured, in-depth interviews were conducted...
Decades of research on human fertility has presented a clear picture of how fertility varies, including its dramatic decline over the last two centuries in most parts of the world. Why fertility varies, both between and within populations, is not nearly so well understood. Fertility is a complex phenomenon, partly physiologically and partly behaviourally determined, thus an interdisciplinary ap...
Ranking fuzzy numbers plays a very important role in decision making and some other fuzzy application systems. Many different methods have been proposed to deal with ranking fuzzy numbers. Constructing ranking indexes based on the centroid of fuzzy numbers is an important case. But some weaknesses are found in these indexes. The purpose of this paper is to give a new ranking index to rank vario...
The recent decline in fertility in Bangladesh froin a total fertility rate of 6.3 children per women in 1975 to 3.5 in 1995 (MHPC, 1978:73; BBS, 1996) has created interest among researchers, policy makers and academicians. This is because such a dramatic change in fertility has occurred without a substantial improvement in socio-economic status, health conditions and otlier factors thought to b...
