Alzheimer disease is a neurodegenerative condition that affects cognitive, behavioral and global functioning of patients. Currently and due to the lack of conclusive biological testing, Alzheimer's disease diagnosis is based primarily on clinical criteria. Since its early diagnosis allows clinica...

This article attempts to review the main research on web sites that promote Eating Disorders (ED), Pro-ana and Pro-mia. It gives the opportunity to reflect on this growing topic that continues to be not well known. Some questions emerge in relation to the sense of belonging to virtual groups, gro...

The primal-dual column generation method (PDCGM) is a general-purpose column generation technique that relies on the primal-dual interior point method to solve the restricted master problems. The use of this interior point method variant allows to obtain suboptimal and well-centered dual solution...

This paper presents a new warmstarting technique in the context of a primal-dual column generation method applied to solve a particular class of combinatorial optimization problems. The technique relies on calculating an initial point and on solving auxiliary linear optimization problems to deter...

The optimal solutions of the restricted master problems typically leads to an unstable behavior of the standard column generation technique and, consequently, originates an unnecessarily large number of iterations of the method. To overcome this drawback, variations of the standard approach use i...

Oxytocin (OXT) and arginine-vasopressin (AVP) are two phylogenetically conserved neuropeptides that have been implicated in a wide range of social behaviors. Although a large body of research, ranging from rodents to humans, has reported on the effects of OXT and AVP administration on affiliative...

The impact on transportation mode choice of policies implementing metro network expansion, fare subsidies and automobile use and ownership regulation was evaluated econometrically using data for 41 world cities. Controlling socioeconomic and demographic variables, it was found that an increase in...

The Chilean Early Childhood Longitudinal Survey was used to model the choices made by households with respect to day care or preschool (DC/PS) attendance. We also use georeferenced data on the location of centers that could take care of children. We present a detailed analysis of the correlates o...

Studying the evolution of economic thought within a country allows us to trace the history of ideas in a given country and analyze the transfer of ideas across nations. This process is also important in terms of the development of national public policies. In this paper we study the evolution of ...
