BACKGROUND Evolutionary psychology suggests that skin signals aspects of mate value, yet only limited empirical evidence exists for this assertion. OBJECTIVES We sought to study the relationship between perception of skin condition and homogeneity of color/chromophore distribution. METHODS Cropped skin cheek images from 170 girls and women (11-76 years) were blind-rated for attractiveness, ...
Hoare and He’s Unifying Theories of Programming take a relational view on semantics. The meaning of a non-deterministic, imperative program is described by ‘designs’ composed of two relations. They represent terminating states and relate the initial and final values of the observable variables, respectively. Several ‘healthiness conditions’ are imposed by the theory to obtain properties found i...
Boolean-valued predicates over a state space are isomorphic to its characteristic functions into {0, 1}. Enlarging that range to {−1, 0, 1} allows the definition of extended predicates whose associated transformers generalise the conventional wp and wlp. The correspondingly extended healthiness conditions include the new ‘sub-additivity’, an arithmetic inequality over predicates.
Different front-of-pack (FOP) labelling systems have been developed in Europe by industry and organisations concerned with health promotion. A study (n 2068) was performed to establish the extent to which inclusion of the most prevalent FOP systems--guideline daily amounts (GDA), traffic lights (TL), GDA+TL hybrid (HYB) and health logos (HL)--impact consumer perceptions of healthiness over and ...
This research demonstrates that global food products suffer from healthiness bias – a tendency to favor local and evaluate them as healthier than equivalent or foreign products. The paper extends previous findings provides empirical evidence the perception of product’s is driver this phenomenon. Results three between-subject experimental design studies indicate (versus foreign) are associated w...

We present a prototype of a novel interactive food recommender for groups of users that supports groups in planning their meals through a conversational process based on critiquing. The system comprises two novel elements: a user interface and interaction design based on tagging and critiquing, and a utility function incorporating healthiness and diet compliance factors.
