Over the last decade or so, the Internet has become a privileged media for advertisement. Despite this increase in popularity, several studies suggested that Internet users 'avoid' looking at ads (what is often referred to as the banner blindness phenomena). This conclusion, however, rests mostly on indirect evidence that participants do not remember the ad content. Therefore, it is unclear whether participants actually fixated the ads and how their gaze behaviour is related to memory for the ad. In the present study, we investigated whether Internet users avoid looking at ads inserted on a non-search website using an analysis of eye movements, and if the ad content is kept in memory. Our results show that most participants fixate the ads at least once during their website visit. Moreover, even though the congruency between the ad and the editorial content had no effect on fixation duration on the ad, congruent ads were better memorised than incongruent ads. This study provides a novel and systematic method for assessing the processing and retention of advertisements during a website visit.

Compost of poultry manure and olive mill wastes as an alternative fertilizer. Agronomy for Sustainable Development, Springer Verlag/EDP Sciences/INRA, 2006, 26 (2), pp.135-142. hal-00886323 135 Agron. Sustain. Dev. 26 (2006) 135-142Abstract -We studied a compost made of poultry manure, olive mill wastes and mineral-rich wastewater, as an alternative fertiliser. The composts were of high quality, characterized by high levels of nutrients, a relatively low C/N ratio of 15-17 and a fertilizing value similar to that of conventional cattle manure, however without phytotoxicity. Field experiments showed an increase in potato production of 31.5-35.5 t/ha, compared to 30.5 t/ha using cattle manure. The use of olive mill wastewater did not have any negative impact on soil pH, electrical conductivity and phenols. The compost made of poultry manure and olive mill by products appears therefore as a promising ecological alternative to classical fertilizers. poultry manure / olive mill cake / olive mill wastewater / composting / agronomic valorisation of by-products / agro-food industries * Corresponding author: ammarenis@yahoo.fr Article published by EDP Sciences and available at
