Received Jun 9, 2017 Revised Nov 20, 2017 Accepted Dec 11, 2017 The size, structure, and composition of a population are affected by the fertility rates at any point of time. Many researchers took the opportunity to exploit the fertility rates in obtaining better fertility patterns for their country. The curve for the age specific fertility rate is consistent, and this feature allows the curve ...

What we propose here is to reduce the size of Galois lattices still conserving their formal structure and exhaustivity. For that purpose we use a preliminary partition of the instance set, representing the association of a “type” to each instance. By redefining the notion of extent of a term in order to cope, to a certain degree (denoted as α), with this partition, we define a particular family...

We show that fund families allocate their fund managers to different market segments such that their skill is rewarded best. Whether a fund manager’s skill is rewarded by higher alpha depends on the efficiency of the market segment in which she works. Even skilled managers can generate alpha only if the market segment is inefficient. Fund families take this relation between skill and inefficien...

In a nutshell, 21st century regionalism is not primarily about preferential market access as was the case for 20th century regionalism; it is about disciplines that underpin the tradeinvestment-service nexus. This means that 21st century regionalism is driven by a different set of political economy forces; the basic bargain is “foreign factories for domestic reforms” – not “exchange of market a...

The robot platooning problem has been studied extensively by the robotics community under some assumptions such as communication existance and global full observability. In this paper, we consider the platooning problem where the previous assumptions are not valid. In such a context, platooning can be considered as a specific flocking which is a collective decision model. This model can, thus, ...

The Global Program for Elimination of Lymphatic Filariasis calls for mass drug administration for endemic populations outside of sub-Saharan Africa with a single dose of diethylcarbamazine (DEC) and albendazole (Alb) annually for 4-6 years. Single-dose DEC/Alb dramatically reduces blood microfilaria (MF) counts, but most treated subjects fail to completely clear MF after a single dose. A more e...

BACKGROUND Diarrhoeagenic Escherichia coli (DEC) pathotypes are among the most common bacterial causes of morbidity and mortality in young children. These pathogens are not sought routinely and capacity for their detection is limited in Africa. We investigated the distribution and dissemination of DEC in 126 children paired with their mothers in a Nigerian community. METHODS A total of 861 E....
