Smiles Counting the Smiles

This research summary, based on a review of the literature and a series of focus groups with NHS staff, shows that while it is difficult to measure how people feel about their work, there is much to suggest that morale and motivation of the NHS workforce are low. It identifies three key factors that affect morale and motivation: whether staff feel valued, their working environment, and resource...

Frequent SMILES

Predictive graph mining approaches in chemical databases are extremely popular and effective. Most of these approaches first extract frequent sub-graphs and then use them as features to build predictive models. In the work presented here, the approach taken is similar. However, instead of frequent sub-graphs, frequent trees, based on SMILES strings are derived. For this, the SMILES strings of c...

Smiles when sharing

One of the proposed functions of human smiling is to advertise cooperative dispositions and thereby increase the likelihood that a social partner would invest resources in a relationship. In particular, smiles involving an emotional component would be honest signals of altruistic dispositions because they are not easy to produce voluntarily. In this study, 60 people were covertly filmed while i...
