In the present study, we experimentally tested the role of hand motor circuits in simple-arithmetic strategies. Educated adults solved simple additions (e.g., 8 + 3) or simple subtractions (e.g., 11 - 3) while they were required to retrieve the answer from long-term memory (e.g., knowing that 8 + 3 = 11), to transform the problem by making an intermediate step (e.g., 8 + 3 = 8 + 2 + 1 = 10 + 1 ...

This study investigates if contamination perception of personal second-hand products by the previous owner can be used as a clue consumers to evaluate its perceived quality. Data were collected through an electronic survey with 332 Brazilian consumers. Descriptive, correlational, one-way ANOVA and General Linear Model tests performed analyze data. The findings confirm that alter quality and, th...

Cluster ensembles are collections of individual solutions to a given clustering problem which are useful or necessary to consider in a wide range of applications. The R package ̃clue provides an extensible computational environment for creating and analyzing cluster ensembles, with basic data structures for representing partitions and hierarchies, and facilities for computing on these, including...
