Phase formation and evolution in the silicon substituted tricalcium phosphate/apatite system.
TL;DR: The sintering of silicon doped calcium phosphate ceramics prepared from a basic colloidal hydroxyapatite precipitate mixed with silica over 800 degrees C yields a phase mixture of tricalcium phosphate phases (TCP) designated Si-TCP, beta- TCP and a silicon substituted dehydrated apatite (Si-Ap).
Journal ArticleDOI
Motivation, money, prestige and cheats
TL;DR: This paper investigated the effects of supervision and incentives on subjects' performance and cheating behavior in a real effort task and found that lack of supervision promotes cheating, though workers tend to cheat moderately; both economic and social incentives increase motivation but only when workers like their jobs.
Journal ArticleDOI
In vivo imaging of seizure activity in a novel developmental seizure model
TL;DR: A novel in vivo model system of developmental seizures based on the transparent albino Xenopus laevis tadpole is characterized, which allows direct examination of seizure activity, and seizure-induced effects on neuronal development within the intact unanesthetized brain.
Journal ArticleDOI
Metaplasticity governs natural experience-driven plasticity of nascent embryonic brain circuits.
Derek Dunfield,Kurt Haas +1 more
TL;DR: It is found that specific patterns of visual stimuli shift population responses toward either potentiation or depression in an N-methyl-D-aspartate receptor (NMDA-R)-dependent manner and implicate metaplasticity as a natural property regulating experience-dependent refinement of nascent embryonic brain circuits.
Journal ArticleDOI
Peer effects in unethical behavior: standing or reputation?
TL;DR: It is shown that working in the presence of peers is an effective mechanism to constrain honest/dishonest behavior compared to an isolated work situation, and that reputation holds great importance in a worker’s self-image acting as a strong social incentives.
