This study examined the potential moderating roles of career officer's institutional intention and occupational intention on the relationship between structural/content career plateaus and job involvement in Taiwanese career military officers. Empirical data were collected from 338 career officers who received full-time training at the National Defense University in Taiwan. The results showed that the perception of structural/content career plateaus were both negatively related to job involvement. Furthermore, the results found the supports of the moderating role of institutional intention in the relationship between perceived structural/content career plateaus and job involvement, and the moderating role of occupational intention in the relationship between perceived structural career plateau and job involvement. Practical management and research implications are discussed, and future research directions suggested.

This paper aims to develop a model delineating the relationship between altruistic concern for prosocial motives/felt accountability for impression management motives of voice behavior and employees' career success. The model proposed in this study argues that the relationship between motives and career success depends on the voice behavior mediating mechanism and the moderating effect of supervisor-attributed motives on the relationship between voice behavior and career success. The results stress the importance of the context of supervisor attribution motives in linked voice behavior and career success. Overall, our model attempts to address these concerns by highlighting in particular the role of the perspective of supervisor attribution motives to advance the body of knowledge about voice behavior and career success. Practical and theoretical implications are addressed on the basis of the research findings as well as suggestions for future research in the employee voice behavior field.

In the vehicular ad hoc network, moving vehicles can keep communicating with each other by entering or leaving the network at any time to establish a new connection. However, since many users transmit a substantial number of messages, it may cause reception delays and affect the entire system. A certificateless aggregate signature scheme can provide a signature compression that keeps the verification cost low. Therefore, it is beneficial for environments constrained by time, bandwidth, and storage, such as vehicular ad hoc network. In recent years, several certificateless aggregate signature schemes have been proposed. Unfortunately, some of them still have some security and privacy issues under specific existing attacks. This article offers an authentication scheme that can improve security, privacy, and efficiency. First, we apply the certificateless aggregate signature method to prevent the onboard unit devices from leaking sensitive information when sending messages. The scheme is proven to be secure against the Type-1 [Formula: see text] and Type-2 [Formula: see text] adversaries in the random oracle model under the computational Diffie–Hellman problem assumption. Then, the performance evaluation demonstrates that our proposed scheme is more suitable for deployment in vehicular ad hoc network environments.
