压舱水成为海洋污染的万恶之源 不少人把压舱水说成是万恶之源,国际组织、地区法规和各国政府有关压舱水的限制和处罚越来越严厉,但是在如何彻底解决船舶压舱水课题上却遇到难以想象的严峻挑战。不少志士仁人煞费苦心,采用形形色色的解决方法对付压舱水,其中有过滤、加热、紫外线照射、臭氧处理、脱氧、电离、化学杀虫剂,等等,这些方法各有神通,但是无法从根本上更不可能一劳永逸地解决船舶压舱水给海洋水资源带来的种种祸害。 相似文献

The introduction of the tonnage tax for shipping companies has been a response to the declining fleets in many European countries. There are strategic and commercial reasons why a maritime presence is desirable, not least of which is to maintain an important skill base. Although regimes have differed they all offer some form of preferential rates of tax for those ships on the register. In certain cases this tax subsidy has been linked to a requirement to train seafarers, notably in the UK. This article analyses the impact of the tonnage tax system and its success in achieving its objectives of fleet expansion and employment with particular reference to the UK. 相似文献

Worldscale is the dominant system for setting freight rates in ocean-tanker shipping. Its structure is hampered by administrative rigidity which easily disguises the effects of rate changes and complicates the comparison of rates between vessel size segments. The angle is the charterer's, and the shipowner is left to his/her own devices. The sparseness of spot rates between ports (not regions) and the individuality of flat rates due to varying port charges, make functional generalizations between Worldscale (WS) and time charter equivalents (TCE) hazardous. The publishing of rate parameters for all ship segments and possibly port charges for each port would substantially upgrade the value of the system. 相似文献

作为我国传统法中特有物权制度的典权制度,在存续的近两千年里,的确起过重要的作用,但终因失去了,存在的社会、文化基础渐趋灭亡,其功能也多由其他更好的制度代替,因而在物权立法中已无规定的必要。 相似文献

Sejoon Kim 《Coastal management》2018,46(3):222-234
The release of captive dolphins (Tursiops aduncus) from South Korean marine parks, which occurred in 2013, 2015, and 2017, is described and evaluated for its usefulness for conservation of coastal ecosystems. The campaign to free the dolphins created a flagship species, uniting the efforts of national government agencies, local government, and NGOs. However, the Korean management agencies framed the release as a species-specific conservation intervention, while the NGOs brought forward welfare-based demands for the curtailment of cetacean captivity. We argue that the release of the Korean dolphins changed the policy climate, to facilitate two major policy changes: revision of anti-whaling regulations to prohibit capture of cetaceans for exhibit, and improvement of regulations for rescue, rehabilitation, and release of stranded marine animals. Tradeoffs between welfare and conservation concerns are described in terms of risk for the management agency, welfare for the animals, and feasibility of a continued commitment to maintain the viability of the dolphin stock in the wild. The release of captive animals to their native range relies on a single-species conservation focus which poses little risk for management agencies but does not guarantee their continued commitment. 相似文献
