WWW information access is based on search engines. Most of the users consider a single search engine that they will use whatever their queries are. Additionally, current search engines follow a general framework and they treat all the queries in the same way. In this paper, we present experiments that show that considering variability both in terms of systems and in terms of queries would impro...

Studies investigating fertility decline in developing countries often adopt measures of determinants of fertility behavior developed based on observations from developed countries, without adapting them to the realities of the study setting. As a result, their findings are usually invalid, anomalous or statistically non-significant. This commentary draws on the research article by Moeeni and co...

Adaptation is ubiquitous in sensory processing. Although sensory processing is hierarchical, with neurons at higher levels exhibiting greater degrees of tuning complexity and invariance than those at lower levels, few experimental or theoretical studies address how adaptation at one hierarchical level affects processing at others. Nevertheless, this issue is critical for understanding cortical ...
