RESUMO
This paper presents an in-depth study of the stress wave behavior propagating in a Rayleigh-Love rod with sudden cross-sectional area variations. The analytical solutions of stress waves are derived for the reflection and transmission propagation behavior at the interface of the cross-sectional area change in the rod, considering inertia and Poisson's effects on the rod material. Examples solved using the finite element method are provided to verify the correctness of the analytical results. Based on the forward analysis of Rayleigh-Love wave propagation in a rod impacted by a striker rod, an impact-echo-type nondestructive testing (NDT) method is proposed to conduct defect assessment in rod-type structural components with sudden cross-sectional area changes within a cover medium. This proposed NDT method can identify the location, extension, and cross-sectional area drop ratios of an irregular zone in the rod to be inspected.
RESUMO
The topics of employer branding and organization's image and reputation have been well-researched in the literature. However, most empirical studies were conducted in Europe, Australia, or the United States, but very few were conducted in Asia, especially in Vietnam. In addition, the interaction of image and reputation with the availability of information on social media is poorly understood. Using signaling theory for building a research model, we collected data from 206 Generation Z respondents from the logistics sector in Vietnam. Our findings show that (i) employer branding has positively and significantly related to an organization's image and reputation; (ii) the organization's image and reputation had a significant effect on job seekers' intention to apply; and (iii) the interaction of image and reputation with availability of information on social media to predict the job seeker's intention to apply. The paper also presented implications for both researchers and practitioners as well as recommendations for future research.
