Using a unique panel data set detailing individual-level mobile app consumption, this study develops a utility theory-based structural model for multiple discrete/continuous choices in app use. We identify the dynamics and interdependencies between mobile apps and jointly quantify consumers’ app choice and satiation simultaneously. The results suggest that mobile users’ baseline utility is the ...

Sugar-sweetened beverages (SSBs) are thought to be problematic for weight management because energy delivered in liquid form may be less effective at suppressing appetite than solid foods. However, little is known about the relative 'expected satiation' (anticipated fullness) of SSBs and solid foods. This is relevant because expected satiation is an important determinant of portion selection an...

This study examined whether semantic satiation effects for a picture exemplar differ from a word exemplar. If massive repetition of the category name leads to an inhibition of conceptual processing, then semantic satiation effects would be found in both the word and picture exemplar conditions. However, if the repetition leads to an inhibition of lexical processing, then effects would be found ...

Verbal satiation of Chinese bisyllabic words was studied in three experiments to ascertain the phenomenon, to track its time course, and to identify its locus. Experiment 1 asked the participants to judge if an exemplar matched a category in 22 blocks of 40 trials each. Within a block, one category appeared 20 times (repeated trials) while each of the remaining 10 categories appeared only twice...

Last November, Jacques Diouf, Director-General of the FAO, called together a World Summit on Food Security in Rome. Seven of the leaders of the G8 countries (the USA, Russia, Japan, Germany, France, the UK, Canada and Italy) failed to attend (only Italy’s prime minister was present). Nevertheless, we would like to see a favourable development from the 2009 meeting, held at a time in history whe...

The participants at the food summit organized by the Food and Agriculture Organization (FAO) in 1996 pledged to reduce the number of hungry by half by 2015. Measuring and quantifying food insecurity is a crucial component of making progress towards that goal. This paper presents one possible approach towards measuring what share of the population might be affected by food insecurity and to what...
