An analysis of the pricing system in the Greek–Italian coastal routes

Price discrimination is practiced by oligopolistic coastal shipping companies in the ‘unregulated’ Greece–Italy routes in the year 2002. Investigation has been carried out ‘per route’—in a doctoral thesis—instead of ‘per market’ which was the so-far erroneous approach of shipping economists. This is so for a host of differentiating factors play a considerable and non-negligible role (like geography, distance, demand, seasonality and others). Service—and price-discrimination—in coastal shipping is affected also by the predetermined ship design which thus is a special feature—but not exclusively—in coastal shipping. Companies in the Adriatic Sea try to extract the greater possible value of the user's willingness to pay, peak and off-peak, group and ungrouped, for social groups (clubs, families and students). Marketing and economics interfere in a complicated—far from the nice world of theory—situation, where maximization of revenue and profit, capacity utilization, intense seasonality and high fixed cost (common and joint costs as well) are a few of the factors that interplay. This paper can be considered as a case study for applied pricing. Excess capacity is also a strategic factor affecting pricing. It is our opinion that the analysis here gives for the first time a complete theoretical and practical account—based on the price lists of the companies—of the pricing policy of the ferry boats running in the Adriatic Sea belonging to coastal shipping companies connecting Italy with Greece and Greece with the European Union (EU). We believe this work to be useful for maritime Europe.     

加肋锥—环—柱结合壳初始几何缺陷形态分析

根据加肋锥—环—柱结合壳加工建造过程,分析其中可能产生初始几何缺陷的环节和关键因素。同时参考现行规范,根据大量环肋薄壳结构的建造经验,分别对肋骨与壳板初始几何缺陷的形态进行分析,并与已建模型存在的初始几何缺陷测量值进行对比,进一步验证建造经验的可靠性。结果表明:锥—环—柱结合壳初始几何缺陷主要因肋骨与壳板的角焊缝及壳板之间的环焊缝产生;具有不同半波数的肋骨初挠度以及壳板凹凸度等为典型的初始几何缺陷形态。所得结果可为后续探寻初始几何缺陷对锥—环—柱结合壳力学性能的影响提供参考。

     

污垢组合对印度玛纳尔湾水域低碳钢腐蚀行为的影响研究(英文)

Corrosion behaviour and biofouling characteristics of mild steel in three different coastal locations in the Gulf of Mannar,India have been studied over a period of 24 months.Oyster fouling was predominant at Open sea-Tuticorin,while barnacle fouling was dominant at both Mandapam and Harbour-Tuticorin.The rate of corrosion for 24 months exposure period was highest at Mandapam,where fouling was minimal.The surface of the mild steel was characterized by etchings&crevices beneath the hard foulers attached on it,at all the test locations.The depth of crevice caused by hard foulers was higher at Open sea-Tuticorin followed by Harbour-Tuticorin and Mandapam.The loss in ultimate tensile strength was more in Open sea-Tuticorin than the other two locations.Corrosion behaviour of mild steel is discussed based on the variation in the biofouling assemblage at the three test locations.

Safety, security, the environment and shipping: The problem of making effective policies

This paper examines where problems of shipping policy jurisdiction between international, supra-national and national levels have occurred. These range across the issues of public goods — safety, security and environment— and show up inadequacies in the current shipping policy-making processes. New frameworks — commonly termed “polycentric governance” and “multi-level governance”— sensitive to the complexities of the maritime industry and its associated political structure urgently need to be adopted. The paper is based upon research work recently carried out across the European Union supported by a number of publications and will include examples from Greece, the United Kingdom, Spain, France and also the new member states. Suggestions for improvements in policy-making structures will be made and recommendations put forward for consideration by policy-makers in the maritime sector at all jurisdictional levels

海河河口挡潮闸的泥沙问题

本文根据辽河河口西水道、海河河口建闸前后与套尔河河口的实测资料,总结出淤泥质河口的河床演变,除纳潮量而外,还有三个重要的动力参变数:a.年径流量/年纳潮量即Qr/Qt的比值,b.纳潮量沿程递减率(涨潮)及递增率(落潮)即ΔQt/Δx,c.时段年输沙量减少/时段年径流量减少即ΔG/ΔQr。对于海河河口闸下减淤问题,根据上述与河床演变有关因素,作出了建议:a.把河口段改建成半潮汐通道,及b.提出修建闸下防沙导流堤的原则。     

Governance Responses to Rapid Growth in Environmentally Sensitive Areas of Coastal Australia

The twin forces of rising affluence and population are altering coastal communities around the world. High amenity, environmentally sensitive areas—particularly attractive, non-metropolitan coastal environments—are witnessing a tidal wave of in migration from former urbanites. As a result, these communities are struggling to accommodate growing numbers of people with urban tastes and rural dreams in areas with governance structures and physical infrastructure designed for occasional tourists. This article looks at how governance frameworks in coastal Australia respond to the profound environmental, social, and cultural implications of this process. We offer a typology of non-metropolitan coastal growth settings—from exurban contexts to isolated coastal hamlets—and identify the main environmental, social, economic, and governance issues they face. We then outline the policy and legislative framework governing coastal areas in Australia and show how this framework is interpreted at the local level through an analysis of five local plans covering different coastal settings.
