Metaheuristic design of feedforward neural networks: A review of two decades of research
(2017)Engineering Applications of Artificial IntelligenceOver the past two decades, the feedforward neural network (FNN) optimization has been a key interest among the researchers and practitioners of multiple disciplines. The FNN optimization is often viewed from the various perspectives: the optimization of weights, network architecture, activation nodes, learning parameters, learning environment, etc. Researchers adopted such different viewpoints mainly to improve the FNN's generalization ...Journal Article -
The Restructuring of South American Soy and Beef Production and Trade Under Changing Environmental Regulations
(2017)World DevelopmentIn response to the extensive loss of forests caused by soy and cattle expansion in South America, several countries have increased their legal restrictions on deforestation, and stepped up their enforcement. In addition, in the Brazilian Amazon, new private agreements were initiated in 2006 and 2009 to limit the purchase of soy and cattle linked with deforestation. One concern is that such policies, because they are spatially heterogeneous ...Journal Article -

Trading off nutrition and education? A panel data analysis of the dissimilar welfare effects of Organic and Fairtrade standards
(2017)Food PolicyMillions of smallholder farmers in developing countries participate in different types of sustainability standards. A growing body of literature has analyzed the welfare effects, with mixed results. Yet, there are important knowledge gaps. First, most existing studies have looked at the effects of one standard in one country. When comparing between studies it is unclear whether dissimilar outcomes are the result of different standards or ...Journal Article -
La arquitectura en su dimensión temporal
(2017)Bitácora arquitecturaEl tiempo somos nosotros, por lo tanto resulta indispensable hablar de él y comenzar por aquéllos que han pensado en el tiempo a lo largo de la historia desde distintos enfoques. Se reflexionará después sobre los cambios y las posibilidades que puede traer consigo, para concluir con un acercamiento a la arquitectura en su estrecha relación con el tiempo y su “muerte,” la cual se propone contemplar como un ciclo de inicios perpetuos.Journal Article -
Assessing snow instability in skier-triggered snow slab avalanches by combining failure initiation and crack propagation
(2017)Cold Regions Science and TechnologyDry-snow slab avalanches start with a local failure in a weak snowpack layer buried below cohesive snow slab layers. If the size of the failed zone exceeds a critical size, rapid crack propagation occurs possibly followed by slab release if the slope is steep enough. The probability of skier-triggering a slab avalanche is generally characterized by classical stability indices that do not account for crack propagation. In this study, we ...Journal Article -

How do Students Learn to See Concepts in Visualizations? Social Learning Mechanisms with Physical and Virtual Representations
(2017)Journal of Learning AnalyticsSTEM instruction often uses visual representations. To benefit from these, students need to understand how representations show domain-relevant concepts. Yet, this is difficult for students. Prior research shows that physical representations (objects that students manipulate by hand) and virtual representations (objects on a computer screen that students manipulate via mouse and keyboard) have complementary advantages for conceptual ...Journal Article -
Chloride-induced corrosion of steel rebars in simulated pore solutions of alkali-activated concretes
(2017)Cement and Concrete ResearchThe passivation and chloride-induced depassivation of steel rebars immersed in varying alkaline environments (0.80 M, 1.12 M and 1.36 M NaOH solutions), simulating the pore solutions of low-Ca alkali-activated concretes, were investigated using a range of electrochemical techniques. The passive film on the steel rebars was complex in chemical makeup, composed of Fe–hydroxides, oxy-hydroxides and oxides. An increased degree of passivation ...Journal Article
