Social Incentives Matter: Evidence from an Online Real Effort Experiment Contributing to a social cause can be an important driver for workers in the public and nonprofit sector as well as in firms that engage in Corporate Social Responsibility activities. This paper compares the effectiveness of social incentives to financial incentives using an online real effort experiment. We find that soci...

We investigate methods for modelling metabolism within populations of cells. Typically one represents the interaction of a cloned population of cells with their environment as though it were one large cell. The question is as to whether any dynamics are lost by this assumption, and as to whether it might be more appropriate to instead model each cell individually. We show that it is sufficient ...

For a wind energy system, main speed-increasing gearboxes, pitch drives and yaw are composed of multistage planetary gear system. However, inevitable errors in the manufacturing assembling gears lead to uneven load distribution system; thus, its service life reliability decrease greatly, which would eventually affect normal operation whole power In this study, dynamic sharing model drive is est...

Current distribution on a 2-layer PCB with lumped circuits is estimated by measuring the near electric field. In this method, the current estimation model is made without considering the electrical parameters of lumped circuits. Experimental results are demonstrated and compared with the numerical results, confirming the validity of this method. key words: measurement, current distribution, nea...

A transmission line model for capacitors is proposed and developed. The model relates electrical parameters to geometrical parameters, leading to simple design rules for power applications. In contrast, design rules based on lumped RLC models are shown to lead to design errors. Experimental results match a simulation based on the distributed model whereas a lumped model gives erroneous predicti...

Abstract To avoid the failure under longitudinal, shear, and mixed wave from earthquake, an archetypal vibration isolator based on a smooth discontinuous (SD) oscillator is proposed. This model comprises lumped mass mounted by vertical spring horizontal elastic continuum, which separately provides positive negative stiffness forming stable quasi-zero (SQZS) in all directions. The equation of mo...

In this study, the dispersion of an infinite shear beam with a lumped mass connected at periodic distances and resting on elastic foundation was examined. The effect periodicity in finite region masses wave propagation investigated through one-dimensional model. relationship for Bragg scattering, which consists masses, derived using transfer matrix method. Subsequently, to evaluate parameters s...

Numerical modeling and experimentation are used at Xerox Office Group to design, optimize, and verify the fluid dynamic behavior of phase-change ink jets, including the individual jets in a print head. A typical model of an ink jet is based upon lumped-parameter (no spatial variation) assumptions. While quite accurately predicting the main Helmholz resonant frequency (a key performance measure)...
