Two studies documented and evaluated parental scaffolding of 3and 4-year-olds' spatial communication. In Study 1, children gave directions to parents about locations of objects. Three-year-olds gave ambiguous directions more often than 4-year-olds, and parents used directive prompts more often with 3-year-olds than 4-year-olds, Study 2 compared the effectiveness of parental prompts in a control...

In 4 studies, the authors examined the impact of categorization on the recollection of ethnically ambiguous faces. Participants were presented with faces lying at various locations on mixed-race continua (i.e., Caucasian-North African and Caucasian-Asian faces were used as source images in a morphing program). In all studies, the prevalence of exclusive ethnic features in a face distorted parti...

Increasingly user-generated content is being utilised as a source of information, however each individual piece of content tends to contain low levels of information. In addition, such information tends to be informal and imperfect in nature; containing imprecise, subjective, ambiguous expressions. However the content does not have to be interpreted in isolation as it is linked, either explicit...

How to sign an electronic contract online between two parties (say Alice and Bob) in a fair manner is an interesting problem, and has been studied for a long time.

Crowdsourcing is a distributed approach in which people participate and share information over the Web (e.g. Facebook or Twitter). This distributed model has proved to be helpful in accelerating the perception of what occurred, where it happened, and who needed help in recent disasters such as the Boston Marathon bombs, the Oklahoma tornado or the Central Europe floods. Nevertheless, this kind ...
