If your language did not have words for numbers, would you be able to think about numeric quantities? An Amazonian culture where number words are limited to one, two and many has provided new insights to the interaction between thought and language.

BACKGROUND We use data from rural Nepal and South India to compare the prevalence of small-for-gestational-age (SGA) and neonatal mortality risk associated with SGA using different birth-weight-for-gestation reference populations. METHODS We identified 46 reference populations in low-, middle-, and high-income countries, of which 26 met the inclusion criteria of being commonly cited and havin...

In the probabilistic track of the IPC5 —the last International Planning Competitions— a probabilistic planner based on combining deterministic planning with replanning —FF-REPLAN—outperformed the other competitors. This probabilistic planning paradigm discarded the probabilistic information of the domain, just considering for each action its nominal effect as a deterministic effect. Thus, in ce...

This article explores the effect of external representations on numeric tasks. Through several minor modifications on the previously reported two-digit number comparison task, we obtained different results. Rather than holistic comparison, we found parallel comparison. We argue that this difference was a reflection of different representational forms: The comparison was based on internal repres...

Not only is the operating plan the basis of organizing marshalling station's operation, but it is also used to analyze in detail the capacity utilization of each facility in marshalling station. In this paper, a long-term operating plan is optimized mainly for capacity utilization analysis. Firstly, a model is developed to minimize railcars' average staying time with the constraints of minimum ...

This paper presents a tool developed to obtain qualitative trend representations from signals, Qualtras. The aim of such a type of description is to offer an understandable representation of process behavior based on the concept of qualitative episode. The tool is intended to be used as a numeric to qualitative interface for supervisory applications. The applicability of this tool is demonstrat...

Purpose—The purpose was to determine the number of semantic neighbors, namely semantic set size, for 88 nonobjects (Kroll & Potter, 1984) and determine how semantic set size related to other measures and age. Method—Data were collected from 82 adults and 92 preschool children in a discrete association task. The nonobjects were presented via computer, and participants reported the first word tha...

Greater numeracy has been correlated with better health and financial outcomes in past studies, but causal effects in adults are unknown. In a 9-week longitudinal study, undergraduate students, all taking a psychology statistics course, were randomly assigned to a control condition or a values-affirmation manipulation intended to improve numeracy. By the final week in the course, the numeracy i...
