Maritime security guidelines: a study of Swedish ports’ perceived barriers to compliance

ABSTRACT

Due to the constant risk of piracy and terrorist attacks which cause disturbances within international shipping of goods, barriers to the adoption of maritime security guidelines (MSGs) at European ports have become prevalent. In this paper, a conceptual framework was created to explore the perceived barriers that prevent compliance with MSGs. To verify the conceptual framework, empirical data were collected using a mixed-methods approach, which was comprised of interviews with national experts and a survey of 47% of Swedish ports involved in the shipping of goods. According to the presented framework, the perceived barriers of Swedish ports to compliance with MSGs were linked to collaborations within the Swedish Maritime Security stakeholder network, available resources and educational knowledge about security culture. In addition, the perceived barriers of smaller ports were linked to the adaptation to MSGs at different levels and the absence of specific tools of maritime security management. Due to an increased interest in international shipping of goods, this paper is currently one of few that addresses the barriers to compliance with MSGs. Moreover, the paper presents a general conceptual framework, novel managerial implications and recommendations for future research.     

Online channel strategies under different offline channel power structures for the Belt and Road of China

ABSTRACT

This paper explores the online channel strategies adopted by Chinese manufacturers with regard to the Belt and Road. It also investigates the effect of offline channel power structures and maritime transportation costs on online channel mode selection and pricing strategies. The offline channel power structures are classified into three types, namely, Chinese manufacturer Stackelberg (MS) structure, vertical Nash (VN) structure, and foreign retailer Stackelberg (RS) structure. Furthermore, a game model is developed among the Chinese manufacturer, foreign retailer, and cross-border e-tailer to investigate the interactions among offline channel power structures, maritime transportation costs, and Chinese manufacturers’ online channel mode selection. The results show that Chinese manufacturers’ preferences for the online agency selling mode increases correspondingly with the decrease in their market position and bargaining power. Moreover, foreign retailers can obtain higher profits in the online agency selling mode under the VN structure. However, the level of profit for foreign retailers depends on the intensity of their competition with cross-border e-tailers under the MS and RS structures. Finally, consumers in countries along the Belt and Road can obtain a higher surplus in the online agency selling mode under all of the structures.

网络数据融合技术在MITS中的应用研究

探讨了基于传感器网络的数据融合技术在海事智能交通系统(MITS)中的应用问题,为该领域的进一步研究提供一些有价值的思路和见解。基于目前研究遇到的困境,提出将MITS抽象成一个无线传感器网络(WSN),从而可在WSN环境下引入数据融合技术来研究海事智能交通系统中的各种信息处理问题,如船舶的定位与导航以及避碰等;紧接着,总结了现有定位、导航、避碰和船舶安全管理技术研究的现状并分析了存在的主要问题;针对基于GPS的MITS存在的种种弊端,结合各国卫星定位导航系统的建设现状,提出利用MITS内其它元素的信息和多源信息融合技术来实现船舶的相对定位和导航这一新思路;最后,从网络数据融合技术角度出发,具体指出了MITS网络融合系统构建时所必须考虑的一些基本问题,并给出该融合系统的一般性框架。

关于海事人为因素的层次分析法

航海是一项有风险性的行业,船只在航行中遭遇自然灾害和意外事故导致人身和财产损失的情况是比较常见的。一直以来航运界都在企图找到发生海上事故的原因以减少损失、降低风险,在气候、环境、船舶结构、设备诸方面都做了研究,却收效甚微。其实再先进的船舶也得由人来操纵,人的素质高低对船舶航行的安全有着主要的影响。本文将探讨用层次分析法对导致海事发生的人为因素进行分析。
