“民间文学”与“俗文学”的交融

本文依据文学三分法(雅文学、俗文学、民间文学)的思想观念,从民间文学与俗文学的概念、特质、研究方式三方面,具体描述和分析了两学科的重合和差异之处,发现两学科无论在研究对象还是研究范围等方面都存在含混不清之处。通过对两学科重合和差异处的具体描述和详细分析,重新思考当代语境下两学科如何借助其他视角和理论进一步拓展研究领域和深度。     

Airport system planning—a U.K. study

There is growing public pressure, from environmentalist groups and others, for the imposition of lorry bans in urban areas. In the U.K. such bans have so far only been imposed as through‐route bans by small towns, such as Windsor, where the overall impact on operators and on road freight costs is limited. The Greater London Council's response to the pressure for lorry bans has been to set up a Committee of Inquiry to examine the impact of an access ban on the heaviest lorries in the London area. The proposed ban would apply to an area enclosed by the M25 orbital motorway within which vehicles above a specified gross tonnage would not be allowed to operate. A number of metropolitan authorities elsewhere in the U.K. are thought to be considering similar restrictions on lorries.

In this paper, the impact of area lorry bans on goods vehicle operating costs is discussed. It is suggested that practices based on “direct distribution” techniques may prove less costly than the operating alternatives that have been evaluated in the past which include public transhipment depots and the exclusive use of small vehicles.

航海英语教学的主要矛盾分析及其解决方案

航海英语教学实施多年以来始终存在不如意的窘况,问题的症结在于两组主要矛盾：即航海英语教学的定性与航海英语教师的身份的矛盾;航海英语听说与阅读教学的矛盾.航海英语教师应在充分认识到自身身份和责任的基础上,提高个人的专业英语教学和科研能力,使之与较强的听说读写译的语言能力相结合,进一步完善大学英语教学的全过程;认识并理顺通过阅读教学传授语言知识,通过听说实践提高学生的表达技能的关系,使学生的阅读和听说能力得到有机的双向提高.     

南黄海辐射沙脊群西洋水道质点示踪数值模拟

基于二维水动力数学模型和现有西洋垂线流速分布公式,运用Lagrange质点示踪法计算分析了南黄海辐射沙脊群北部西洋水域的质点运动轨迹,并与投放到该海域的GPS漂流浮标运动轨迹作比较,计算结果与实测浮标漂流轨迹吻合良好。模拟结果表明,西洋水域的涨潮表层流速最大可达3.5 m/s,落潮流速最大可达2.0 m/s,水质点运动主要沿着主槽方向,当质点运动到潮流沙脊区域,其运动会发生偏移,Lagrange余流方向指向南面。

Risk aversion,regret aversion and travel choice inertia: an experimental study

This paper presents the results of an experimental study into the role of risk aversion and regret aversion as codeterminants of travel choice inertia. Theoretical results published by Chorus and Dellaert are tested empirically. More specifically, the expectation is tested that when (1) travelers are risk averse, (2) the quality of travel choices is uncertain, and (3) the quality is partially revealed upon usage, travel choice inertia emerges as a learning-based lock-in effect. In addition, this paper studies the role of regret aversion as a possible trigger of travel choice inertia. Analyses are based on data collected in an experiment, where the reward that participants obtain is a function of the outcome of choices they make. Empirical results suggest that the learning-based lock-in effect indeed plays a role in the context of our data. The evidence for the hypothesis that regret aversion triggers inertia is mixed at best.
