Moral disengagement of hotel guest negative WOM : moral identity centrality, moral awareness, and anger

Adopting a moral identity perspective, this research examines the moral judgment of hotel guests’ vindictive negative word of mouth (WOM) toward hotel service failure. This research finds that people with higher moral identity centrality are less prone to moral disengagement of vindictive negative WOM, especially when their moral awareness of the behavior is higher. However, even these individuals may engage in moral disengagement of vindictive negative WOM, if they have higher anger toward the service failure, and when their moral awareness is lower. These findings highlight the significant roles of moral identity centrality, moral awareness, and moral emotion for people’s moral judgment. Practically, this research suggests hotels may manage customer vindictive negative WOM by raising moral awareness and appeasing anger

Electronic origin of spin-phonon coupling effect in transition-metal perovskites

By applying Wannier-based extended Kugel-Khomskii model, we carry out first-principles calculations and electronic structure analysis to understand the spin-phonon coupling effect in transition-metal perovskites. We demonstrate the successful application of our approach to SrMnO$_3$ and BiFeO$_3$. We show that both the electron orbitals under crystal field splitting and the electronic configuration should be taken into account in order to understand the large variances of spin-phonon coupling effects among various phonon modes as well as in different materials.Comment: 5 pages, 1 figur

Extended First-Principles Molecular Dynamics Method From Cold Materials to Hot Dense Plasmas

An extended first-principles molecular dynamics (FPMD) method based on Kohn-Sham scheme is proposed to elevate the temperature limit of the FPMD method in the calculation of dense plasmas. The extended method treats the wave functions of high energy electrons as plane waves analytically, and thus expands the application of the FPMD method to the region of hot dense plasmas without suffering from the formidable computational costs. In addition, the extended method inherits the high accuracy of the Kohn-Sham scheme and keeps the information of elec- tronic structures. This gives an edge to the extended method in the calculation of the lowering of ionization potential, X-ray absorption/emission spectra, opacity, and high-Z dense plasmas, which are of particular interest to astrophysics, inertial confinement fusion engineering, and laboratory astrophysics

Moral identity centrality and cause-related marketing : the moderating effects of brand social responsibility image and emotional brand attachment

Cause-related marketing (CRM) is a popular hybrid marketing tool that incorporates charitable initiatives and sales promotion. CRM has strength in simultaneously encouraging consumer purchases and doing something good for the society. Drawing on the moral identity-based motivation model, this research examines how consumer MI influences consumer behavioural response to CRM. Two field experiments were conducted to test a series of hypotheses relating to the conditional effect of MI on behavioural response to CRM. Brand social responsibility image and emotional brand attachment positively moderated the relationship between consumer moral identity centrality and intention to purchase CRM sponsor brand. The findings contribute to the literature on CRM, moral identity-based motivation of consumer behaviour, and emotional brand attachment

Mechanical design and analysis for a low beta squeezed half-wave resonator

A superconducting half-wave resonator (HWR) of frequency=162.5 MHz and {\beta}=0.09 has been developed at Institute of Modern Physics. Mechanical stability of the low beta HWR cavity is a big challenge in cavity design and optimization. The mechanical deformations of a radio frequency superconducting cavity could be a source of instability, both in continues wave(CW) operation or in pulsed mode. Generally, the lower beta cavities have stronger Lorentz force detuning than that of the higher beta cavities. In this paper, a basic design consideration in the stiffening structure for the detuning effect caused by helium pressure and Lorentz force has been presented. The mechanical modal analysis has been investigated with finite element method(FEM). Based on these considerations, a new stiffening structure has been promoted for the HWR cavity. The computation results concerning the frequency shift show that the low beta HWR cavity with new stiffening structure has low frequency sensitivity coefficient, Lorentz force detuning coefficient KL and stable mechanical property.Comment: this work is supported by Strategic Priority Research Program of CAS (Grant No. Y1020700ADS)and National Natural Science Foundation of China (Grant No. 91026001
