中国艺术品海外回流新现象

在今年中国嘉德春拍中,有一件《南宋四朝宸翰》书法手卷格外引人注目.不仅是因为这件拍品是集南宋前四位皇帝高宗、孝宗、光宗、宁宗御书诗为一卷,更为重要的是,这件拍品曾经出现在2012年纽约苏富比的亚洲艺术周上,当时估价75万至100万美元,最终以568.25万美元成交,成为了当年纽约亚洲艺术周书画拍卖的最高价.因而,其再次出现在拍卖市场上,被视为中国艺术品海外回流进入"2.0时代"的一个重要标志.     

Decision support for vessel traffic service (VTS): user needs for dynamic risk management in the VTS

Vessel Traffic Service (VTS) is a shore-side service implemented by a "Competent Authority to improve the safety and efficiency of vessel traffic and to protect the environment". It is a service that operates through VTS centers, from which VTS operators monitor traffic, assist in navigational matters and provide information to all ships in a designated area. As VTS is provided by operators located on shore, they usually make use of several decision support systems to be able to monitor the traffic and to provide information to the vessels. Although several new tools and approaches have been introduced in the VTS domain, there is still room for improvements. This paper summarizes the results from three studies conducted within the EfficienSea project to approach user needs for dynamic risk management in the VTS domain. Data was collected by conducting study visits and observations at VTS centers, a focus group interview as well as several semi-structured interviews. The paper summarizes the results and presents technical and organizational user needs for dynamic risk management within the VTS domain.
