“渡船”与“商船”——论《边城》牧歌形象的裂隙

渡船与商船是《边城》中多重意义的交汇点,它们是湘西社会不可或缺的交通工具,是翠翠、天保或是傩送的欲望对象的替代物,也是这些主人公各自所处社会地位的象征物,同时还是小说文本内部的结构性因素。论文以文化研究的方式,通过对这两个意象的分析,试图揭示《边城》中牧歌形象的裂隙。文章最后认为,这两个意象构成了小说内部幻景与小说外部社会现实之间的一条隐秘通道。     

An integrated modelling approach for raw material management in a steel mill

An integrated modelling approach combining optimisation models with simulation is proposed for coordinated raw material management at steel works throughout the whole supply chain management process. The integrated model is composed of three components: ship scheduling, yard operation simulation and material blending models. The ship scheduling model determines which brands, how much and when they should be arrived, and the problem is modelled as mixed integer linear programming. The simulation model is used to simulate the whole processes from ships’ arrivals to the retrieval of the materials through the berthing and unloading the raw materials. Finally, the raw material blending model is developed for determining the brand and quantity of raw materials to be used. The proposed integrated modelling approach for raw material management has been successfully implemented and applied at steelwork to provide shipping schedules and predict future inventory levels at stock yards. By coordinating all the activities throughout the entire raw material supply chain management process, this article proposes an integrated approach to the problem and suggests a guideline by the appropriate simplification. The quantitative nature of the optimisation model and simulation facilitates an assessment of the risk factors in the supply chain, leading to an evaluation of a wide variety of scenarios and the development of multiple contingency plans. Further research is expected to supplement the ship scheduling models with heuristics for the idiosyncratic constraints of maritime transportation.     

企业所有权安排的交易成本分析

交易成本是影响企业效率的一个重要因素。从交易成本角度来看,所有权安排形式只能根据企业的具体情况来确定,并不存在通用于所有企业类型的最优所有权安排形式。每一种企业所有权安排都有其特定的优势,能够相对较好地解决某种类型的交易成本,因而适用于特定类型和规模的企业。在一定的条件下,人力资本所有者享有企业所有权可以是有效率的企业制度模式。     

华南古板块兴凯地裂运动特征及对油气影响

华南板块新元古代的兴凯地裂运动始于晋宁运动后（800 Ma B. P.）,强烈活动于新元古代中期的苏雄—开建桥组火山岩喷发期（700 Ma B. P.）,结束于中奥陶世的郁南运动（458 Ma B. P.）。演化历程大体相当于Rodinia（罗迪尼亚）超大陆解体时,应为Rodinia 超大陆裂解期的组成部分。兴凯地裂运动在新元古代形成扬子板块的基底,对中上扬子区后期构造变形有重要的影响,为后兴凯期（加里东运动）形成大型古隆起和大形拗陷提供了基础;产生的基底断裂对四川盆地后期构造活动有控制作用;形成的稳定大陆边缘为下组合烃源岩发育提供了条件。     

巴拿马船舶扣押制度及其启示

巴拿马基于与美国海事审判法律制度的历史渊源关系,其船舶扣押制度比较完善。通过船舶登记地法、合同准据法或更密切联系规则等识别船舶优先权,并辅之有效率的扣船程序,吸引世界各地的权利人前往巴拿马扣船。这对完善我国的扣船制度有一定的借鉴作用。

对长江三峡旅游船营运进行了历史回顾和经营反思,对旅游船业经营现状和三峡工程蓄水后的影响进行了分析,根据旅游可持续发展的战略思想提出了旅游船业未来的经营发展对策。     

旅游船管理与服务专业培养模式研究

旅游高等职业技术教育与旅游产业相关,其中旅游船管理成为旅游高等职业技术教育中一站必不可少的课程。对旅游人才的培养有十分重要的作用。     

愚昧与死亡——论美国愚人文学的主题嬗变

关注人类本性和行为的愚蠢及其对自身和社会造成的危害是愚人文学产生和存在的基础。美国的愚人文学由讽刺人类本性和行为的愚蠢到揭示现、当代人类的“无归属感”和“死亡”结局 ,其主题发生了深刻的变化。研究这些愚人文学作品 ,对于从人性的角度揭示人类境遇的规律具有一定的认识论意义。     

融资租赁的资产证券化模式与法律风险控制

航运业作为资本密集型产业,资金来源是其发展的关键所在.船舶融资租赁将融资压力由承租人转向出租人,资产证券化则是将该压力由出租人分散到广大投资者并实现稳定现金流,有效解决此难题.虽然当前国内资产证券化大多采用离岸模式,但主要碍于国内立法和税收制度,其发展是未来趋势所在.文章从国内法角度,分析船舶融资租赁下出租人进行资产证券化的优势和存在的问题,探究一种适合我国未来发展的交易结构.同时,深入分析该交易结构中的法律关系和存在的风险,并结合实际提出相关建议.     

An overview of maritime waterway quantitative risk assessment models

The safe navigation of ships, especially in narrow shipping waterways, is of the utmost concern to researchers as well as maritime authorities. Many researchers and practitioners have conducted studies on risk assessment for maritime transportation and have proposed risk reduction/control measures accordingly. This article provides a detailed review and assessment of various quantitative risk assessment models for maritime waterways. Eighty-seven academic papers and/or project reports are summarized and discussed. The review then proceeds to analyze the frequency and consequence estimation models separately. It should be pointed out that we further summarize the advantages and disadvantages of frequency estimation models and provide recommendations for their application. From the overview, we find that the quantification of the impact of human error is of great importance and should be considered in future studies. Possible solutions are also proposed in the discussions.
