Advances in port studies: the contribution of 40 years Maritime Policy & Management

Port economics, management and policy have progressively emerged as a distinctive research field, and a core part of maritime economics. This paper provides an analysis of all the 267 port studies published in Maritime Policy & Management (MPM) since its inception in 1973. This paper provides a content analysis for seven interrelated research theme categories including main research topics and methods, authorship distribution and citation counts. It is demonstrated that MPM played, and continues to play, a key role in publishing research on seaports. The published research increasingly applies established analytical frameworks to ports. The paper concludes with a discussion on current challenges for port-related research.     

Value creation in the port: opening the boundaries to the market

In the era of fierce competition among ports as elements of value chain systems, the opening of the boundaries to the market represents a crucial challenge that port authority has to cope with, in order to guarantee a lasting economic and social development of the port and its hinterland. We propose a theoretical framework to analyse value creation in the port and its hinterland through two core concepts: resource allocation and interaction. We illustrate such framework with the case of the port of Naples and, specifically, the contribution of the port authority and other port business operators to the value creation process of Garofalo, an export-oriented firm located in its hinterland. A discussion and suggestions for future research are provided in the last section.     

Au40 Pd20合金原子团簇惰性气体氛围凝聚动力学行为研究

采用蒙特卡洛方法,结合Tight-binding和Lennard-Jones作用势,对Ar原子氛围中初始随机分布的40个Au原子和20个Pd原子体系的凝聚动力学行为进行了研究．Ar原子氛围对合金团簇的形成过程及其形貌尺寸有重要影响,计算表明：不同的Ar原子氛围得到的Au40 Pd20合金原子团簇凝聚结构形貌不同;在降温退火过程中, Ar原子密度大时,得到的Au40 Pd20合金原子团簇结构更加紧凑,且Au40 Pd20合金团簇凝聚相变温度更高;而恒温退火过程中,则发现较高温度时能得到较为紧凑的合金团簇结构,Ar原子密度越大,系统到达平衡的动力学时间更短．模拟结果能为惰性气体冷凝方法中实现合金团簇结构与形貌可控制备提供参考．

经济全球化与教育国际化

20世纪末以来,经济全球化的发展呈现出不可逆转的态势。经济的全球化极大地提高了世界范围的人、财、物、技术的流动速度,促进了各种生产要素和资源的优化配置。经济全球化在加强各国之间教育资源交流的同时,也迫使各国的教育市场向全球开放,因此高等教育国际化是应全球化而生,是世界经济一体化进程的必然产物。所谓高等教育国际化,就是加强国际高等教育的交流合作;积极向各国开放国内教育市场,并充分利用国际教育市场;在教育内容、教育方法上要适应国际交往和发展的需要,要培养有国际意识、国际交往能力、国际竞争能力的人才。
