Time banking facilitates generalized reciprocity among neighbors by rewarding contributions in proportion to the time entailed in contributing. Contributions can be person-to-person services, such as driving another person to an appointment. They can also be co-productions, in which the provider and recipient jointly enact a service, such as giving/receiving a guitar lesson. Co-production is an...

The subject of this paper is the attempt to reproduce the CO observed production rate curve of comet Hale-Bopp with a numerical model of the nucleus thermal evolution and chemical differentiation. Three possible mechanisms can contribute to the total measured CO production: 1) sublimation of CO from the nucleus; 2) release of gas of CO trapped in the amorphous water ice in the nucleus; 3) emiss...

High CO(2) concentration (0.5%) increased the rate of ethylene production, measured in a continuous flow system, in intact sunflower (Helianthus annuus L.) plants. However, the rate of ethylene production subsided to near control levels after approximately 24 hours. The effect of high CO(2) could only be observed in light. Although high CO(2) concentration had no effect on the rate of ethylene ...

This study investigates the effect of co-production on customer loyalty (attitudinal and behavioral separately) and factors which may boost co-production in an Iranian bank. To investigate co-production in banking services, the proposed model of Auh et al. (2007) was applied. Given the fact that many banks try to get the status of their main customers, co-production was examined due to its pote...

The promise of co-production to address complex sustainability challenges is compelling. Yet, co-production, the collaborative weaving research and practice, encompasses diverse aims, terminologies practices, with poor clarity over their implications. To explore this diversity, we systematically mapped differences in how 32 initiatives from 6 continents co-produce outcomes for sustainable devel...
