The existing maritime wireless communication sys- tems are presented and the development of the state-of-the-art maritime communication systems is surveyed. Furthermore, a hierarchical and integrated maritime network architecture is proposed to satisfy the increasing various classes of services which demand different Quality of Service （QoS）. Finally, the open issues for further development of maritime communications are identified.展开更多

In order to explore factors that hinder telework adoption in China, this study addresses which individual or environmental factors affect people＇s decision to adopt telework and especially focus on the perception of and attitude toward telework （lllegems et al. 2001） as one of the key factors for telework implementation. By identifying variables that may have an impact on the attitude towards telework acceptance based on the literature reviews, the author collected the data of employees/managers from Chinese organizations through the online survey in 2014. The analyses show that there is statistically significant difference in attitude between men and women, employees and managers, and different marital status and commuting time groups. The findings suggest that China-specific cultural and environmental factors impede the adoption and/or acceptance oftelework.展开更多
