铁路社保综合管理信息系统框架体系研究

铁路社会保障工作是国家劳动保障工作的重要组成部分,随着铁路管理体制改革不断深化和社会经济飞速发展,落后的铁路社会保障工作方式已不能满足社会保障体系继续发展的要求.在对现有铁路社保工作详细调研分析的基础上,提出铁路社保综合管理信息系统的框架体系,描述该框架各部分组成和功能,旨在探讨铁路社保信息化工作的技术思路.     

番茄在冷板冷藏车运输过程中的温度分布

冷板冷藏车在运输过程中,车内货物温度场是影响其运输质量的关键因素之一。本文运用多孔介质理论建立番茄在冷板冷藏车内及货物的数学模型,模拟2种不同堆码方式的动态温度场,并对其变化及分布的特点进行分析讨论,指出堆码方式对货物温度场有一定影响,为有较规则几何形状的果蔬货物的冷藏运输提供了理论依据。     

表面噪声矢量场空间相关特性射线声学建模(英文)

Spatial correlation of sound pressure and particle velocity of the surface noise in horizontally stratified media was demonstrated,with directional noise sources uniformly distributed on the ocean surface.In the evaluation of particle velocity,plane wave approximation was applied to each incident ray.Due to the equivalence of the sound source correlation property and its directivity,solutions for the spatial correlation of the field were transformed into the integration of the coherent function generated by a single directional source.As a typical horizontally stratified media,surface noise in a perfect waveguide was investigated.Correlation coefficients given by normal mode and geometric models show satisfactory agreement.Also,the normalized covariance between sound pressure and the vertical component of particle velocity is proportional to acoustic absorption coefficient,while that of the surface noise in semi-infinitely homogeneous space is zero.     

Leisure mobility styles in Swiss conurbations: construction and empirical analysis

Leisure travel is the most difficult travel purpose to analyse due to the lack of fixed spatial and temporal referents and the consequent flexibility in patterns. This paper addresses lifestyles, social influence, and the travellers’ social networks, issues that have proved valuable for travel behaviour research in confronting the complexity of leisure travel. An approach for constructing leisure mobility styles, based on orientations towards leisure and mobility, will be presented first and then the hypotheses that transport behaviour can be better explained through analysis of leisure mobility styles will be tested. Multivariate analysis reveals that the leisure mobility style group makes a significant contribution towards clarifying variance for the activities ‘Visiting friends and relatives’, ‘Travel participation’, ‘Mode choice’, and ‘Travel distance for leisure’. The use of leisure mobility styles is most useful for developing practical intervention pointers where the in-group homogeneity of lifestyle should be addressed in greater detail.     

石家庄地铁一期运营的社会经济效益研究

本文基于建设项目的费用与效益的识别原则以及有无对比法的思路,分析社会经济效益的构成。以石家庄市地铁1、3号线一期工程为蓝本,从受益者的角度将社会经济效益从轨道交通的建设者、轨道交通的使用者以及社会生态环境等方面系统地阐述城轨交通的建设给城市带来的外部效益。基于以往社会效益量化模型,对石家庄地铁的社会效益进行量化分析,并对其中可量化的效益给出计量模型,最后对石家庄轨道交通一期运营的社会经济效益进行估算。     

从杨丽娟事件看介入式报道的不当对大学生等青少年群体媒介素养的影响

文章回顾了在杨丽娟事件中媒体的介入性报道的种种失误表现,指出了介入性报道对事件的演进过程和悲剧性结局的不当干预作用和影响。文章认为,媒体在使用介入性报道时,必须谨慎小心,坚持新闻报道的客观公正原则,选择正确的报道方法,以期对当代大学生等青少年群体媒介素养有积极的影响。     

人β防御素2和白介素1β在中耳黏膜上皮的表达

目的研究人β-防御素-2(HBD-2)、白介素-1β(IL-1β)在中耳黏膜上皮中的表达情况,探讨其在中耳炎病理发展过程中的作用。方法应用免疫组织化学方法检测慢性中耳炎中耳黏膜上皮及正常外耳道皮肤中HBD-2、IL-1β的表达。结果 HBD-2和IL-1β在中耳炎中耳黏膜的表达较正常外耳道皮肤中上调,有显著性差异(P<0.05);HBD-2和IL-1β在中耳黏膜中的表达有一定的相关性(r=0.9117,P<0.05)。结论中耳炎症状态下,中耳黏膜上皮HBD-2、IL-1β表达上调并可能相互影响,在中耳炎病理发展中发挥一定的作用。     

论传媒对民族文化记忆的唤起

民族文化记忆是确立民族身份、实现民族认同的历史资源.传媒对民族文化记忆的唤起处于一个复杂的"社会文本"中,在"记忆"某些历史的同时也选择性"遗忘"另一些历史;传媒通过纪念仪式和身体实践的方式唤起记忆,并以"拔高"、"简化"和"贴标签"的方式操纵记忆;政治经济权力是传媒建构文化记忆的影响因素,使得传媒对历史的再现出现了局部异化;而随着全球化和网络空间的崛起,多元主体对传媒记忆的解构正在展开,国家人、世界人、个体人的分化成为挑战民族文化记忆建构的一股力量.     

Violation or strengthening of the self-financing doctrine at international airports by SMCP funded PPP schemes?

International airports are among the few examples of transport infrastructures which can well achieve self-financing. The growing interest of private companies in airport construction and operation is the visible testimony to this fact. However, the financing structures of airports are complex, involving not only traffic, passenger and goods handling, but also non-aviation services, such as retail, car parking or intermodal facilities. The integration of social marginal cost pricing schemes into this organizational structure according to the strategic plans of the European Commission, however, is challenging. This paper investigates whether they comply with a second strategic policy objective at European and national level, which is to foster public-private partnerships (PPPs) in transport financing in terms of full cost coverage, risks and incentives.The cases analysed in this paper deal with two sites with very different characteristics: Munich Airport which has been publicly operated since 1991 and the Bulgarian airports Varna and Burgas, which have been managed since 2007 by one concessionaire and whose planning and future development is being accomplished with private capital. The results of both cases showed that self-financing is possible in case congestion costs are considered in the SMCP schemes, and given that air traffic growth rates return to the significant levels prior to the economic crisis. The chapter will discuss the legal implications of congestion pricing at European airports which are violating current EC legislation, as well as the impact of alternative pricing schemes on the environmental performance and technological innovation in aviation.
