试论我国道路交通事故社会救助基金制度

随着我国《机动车交通事故责任强制保险条例》的生效实施，机动车交通事故强制责任保险制度开始运行并发挥作用，然而与之配套的道路交通事故社会救助基金制度的相关立法却尚未到位。本文在分析我国道路交通事故社会救助基金的法律性质、基本功能和法律特征的基础上，对我国道路交通事故社会救助基金制度构建提出相关完善建议。     

��������������BOAӦ���о�

交通信息化提高了交通效率,物联网技术为交通信息化的发展带来更多新技术、新方法,由此产生了“车联网技术”.物联网技术是一种在发展的新技术,故此车联网技术在应用过程中存在一些技术障碍,如车辆细部部件的监控等.本文提出一种通过BOA技术进行交通设备部件访问的服务技术,如果硬件本身具有嵌入式控制接口,通过BOA技术与这种接口集成可以远程对部件进行监控与参数修改.这样BOA通过CAN总线集成的操作可以对设备整体进行全部部件监控和更多的优化操作,甚至可以对BOA设置单独的虚拟IPv6地址,达到更大范围内的远程参数获取与监控.最后,通过具有BOA技术的可控视频监控实例证明,此种技术可行.

On altruists and egoists in activity participation and travel: who are they and do they live together?

Formulation and specification of activity analysis models require better understanding of time allocation behavior that goes beyond the more recent within household analyses to understand selfish and altruistic behavior and how this relates to travel behavior. Using data from 1,471 persons in a recent 2-day time use/activity diary and latent class cluster analysis we identify 11 distinct daily behaviors that span from the intensely self-serving to intensely altruistic. Predicted cluster membership is then used to study within household interactions. The analysis shows strong correlation exists between social role and patterns of altruistic behavior. However, a substantial amount of heterogeneity is also found within social roles. In addition, travel behavior is also very different among altruistic and self-serving time allocation groups. At the household level, a substantial number of households contain persons with similar behavior. Another group of households contains a mix of self-serving and altruistic persons that follow specialized household roles within their households. The majority of households, however, are populated by altruistic persons. Single person households are more likely to be in the self-serving groups but not in their entirety. Altruism at home is directed most often toward the immediate family members. This is less pronounced when we examine altruistic acts outside the home. Konstadinos G. Goulias is a professor of Geography at the University of California Santa Barbara, has been a professor of Civil Engineering at the Pennsylvania State University from 1991 to 2004, and he is the founder and chair of the TRB task force on moving activity-based approaches to practice.

Topology-aware overlay multicast over IP multicast networks

Most existing overlay multicast approaches refuse to consider any network layer support no matter whether it is available or not. This design principle greatly increases the complexity of the routing algorithms and makes the overlay topologies incompatible with the underlying network. To address these issues, topologyaware overlay multicast over IP multicast networks （TOMIMN） was proposed as a novel overlay multicast protocol, which exploits the cooperation between end-hosts and IP multicast routers to construct a topologyaware overlay tree. Through a little modification to protocol independent multicast sparse mode （PIM-SM）, a multicast router is able to receive registration from nearby group members and redirect passing-by join requests to them. Due to the multicast router＇s support, TOMIMN organizes its group members into an overlay multicast tree efficiently, which matches the physical network topology well.
