Narrow Results

This paper provides experimental evidence for the theory of Che et al. (2013, Pandering to persuade, American Economic Review, 103(1), 47–79). Basic communication games with outside options developed by Che et al. (2013, Pandering to persuade, American Economic Review, 103(1), 47–79) are tested in the experiments, and experimental variations with additional conflicts over projects and with private information about outside options are also investigated. Moreover, in these games, strategies concerning delegation have been discussed as well. In general, the experimental results are aligned with the theoretical predictions. As the value of the outside options increases, communication becomes less informative and the experts may pander toward the conditionally better-looking project, the decision makers take their outside options more often and retain their decision rights with higher frequencies.

The under-provision of efforts in built heritage conservation was due to market failure to allocate cost and benefit efficiently. Conservation agency could facilitate conservation effort, which was considered not beneficial from the point of view of the private owners of the heritage houses, by providing conservation subsidy. In this paper, we conducted three different experimental auctions, namely, (i) discriminative price auction, (ii) uniform price auction, and (iii) random nth price auction to investigate bidding behaviors and efficiency levels in allocating conservation subsidies. Both uniform and random nth price auctions were able to encourage cost revealing bids. Random nth price auction was able to engage the off-margin bidders. However, discriminative price auction was more cost efficient compared to the other two auctions.

Reversing Paralysis: Can I Walk Again?

A temperature test apparatus has been designed to measure the temperature rise of the planetary gear train. The experimental platform integrated the temperature test system, siemens operating system and industrial personal computer (IPC). The temperatures of various locations have been investigated under rated condition and the oil temperature-rise time under different speed was estimated. The experimental results indicated that the temperatures of the super-speed planetary gear train (PGT) of the earth pressure balance shield machine (EPBM) rise quickly than the low-speed PGT and the speed has significant influence on the temperature of the PGT. Through comparison the oil temperatures under reverse direction and forward direction, the direction of the motor has little influence on the temperature of the PGT.

The numerical simulation and experiment method for temperature field research in the laser quenching process is proposed. First, several assumptions of the laser quenching process are discussed for the research convenience. The simulation process is analyzed by the Laser Heat-Treatment-2 software, which is developed in FORTRAN. A discrete simulation process and results are given through the setting of different parameters in the laser quenching process. Finally, the experimental study is carried out to demonstrate the validity of the simulation results.
