Accessing the global seafaring labour market

As a global labour market exists for international shipping, a challenging issue facing this industry is to get access to reliable, accurate and timely information of seafarers’ demand and supply. Related to the deregulation environment and great variety in the availability and quality of relevant information, an enquiry into the global seafaring labour market is more complex than a national labour force survey. To cope with the challenge, a novel approach has been developed by the Seafarers International Research Centre (SIRC) at Cardiff University. Viewing capital (ship), labour (seafarers) and services (cargo or passengers) as interconnected and interwoven to each other, it collects and analyses crew lists from main ports world-wide, resulting in the creation of the first global seafarers database. The purpose of this paper is explain its methodological principles, and to illustrate its application potential. Taking the cruise sector as an example, research findings and methodological implications are highlighted.

船舶签证制度应予完善

人与自然的协调发展是一个大趋势,21世纪的中国将以更大的规模,在更广的领域走向海洋,发展海洋经济。海洋经济的发展离不开港口经济的依托,海洋经济和港口经济是相辅相成的。没有海洋经济也就谈不上21世纪的港口经济,没有港口经济也难以发展海洋经济。本文从我国海洋经济与港口经济现状出发,分析构筑海洋经济与港口经济发展的新体系,以供相互探讨。

Maritime search and rescue: Benefit or burden for society?

Just twenty five years have passed since the International Maritime Organization (IMO) provided the legal and internationally harmonized framework for maritime search and rescue operations. While a number of nations only had to adapt their well-established national services it took great efforts for other nations to develop agencies able to fulfil or outstrip minimum requirements. However, the majority of nations (well aware of the humanitarian nature of that task) have been afraid to cope with this challenge and the related financial burdens since the benefits to local, regional, or even national economies are not always clear to the relevant national administrating authorities.

南友公路石灰改良中等膨胀土路堤的试验研究

结合广西南友公路石灰改良膨胀土试验路的修筑，室内试验研究表明宁明盆地的灰白色膨胀土具有中等膨胀潜势，经石灰改良可作为路堤填料，并通过室内试验确定了最优掺灰率；针对普遍利用熟石灰改良膨胀土的“二次掺灰”法，提出了掺加生石灰的“一次掺灰”的施工要点，为类似膨胀土路提的修建提供借鉴。
