A Comparative Perspective on the Paradox of Choice

The paradox of choice leads one to desire more options over fewer options even when there are negative consequences when choosing from larger arrays (choice overload). The paradox of choice may be shared among mammals or it could result from cultural influences relevant to humans. Research with monkeys and young children sheds light on the developmental precursors of the paradox and may highlight the human-uniqueness of this effect. I tested young children (41.5–66.0 months) and monkeys (tufted capuchins, rhesus macaques) to examine choice overload effects. Limited evidence was found that children exhibited choice overload when choosing among six and twelve toys but not when choosing among three toys. No evidence of choice overload was found for monkeys, although this may be due to methodological limitations. Consistent with previous literature on choice and control, monkeys also demonstrated a preference for more options over fewer

Evaluation of the Performance of a Downward Flow Inclined Gravity Settler for Algae Dewatering

With recent concerns over the environmental implications of burning fossil fuels coupled with the depletion of fossil fuel reserves an alternative source of energy isneeded. Algae derived biofuels may be an effective replacement for transportation fuels as they are carbon neutral and have a high area productivity. Algae is superior to terrestrial plants as a biofuel source due to its high oil productivity and efficiency along with the fact that it will not displace food production. Currently the largest obstacle to the implementation of commercial algae to biofuel processes is algae dewatering. The separation of algae from water is difficult due to the dilute concentration of the algae suspension and the extremely low settling velocity of the algae biomass. This work investigates recent improvements to the downward flow inclined gravity settler which has the potential to unlock this much needed process. Additionally, an investigation into algae settling velocity, a field which has received little attention, is also discusse
