翻转课堂教学模式下高校思政课教学改革探究

翻转课堂的核心理念是"先学后教、以学定教。"学生在课前自主学习教师提供的网络教学资源之后,回到课堂进行师生之间、生生之间的面对面交流讨论,这样不仅增加了课堂互动,也能够实现学生个性化学习。结合高校人才培养目标,将翻转课堂教学模式运用于思想政治理论课(以下简称思政课)教学,能够全面提升课堂的互动性,提升思想政治教育的有效性,从而加深学生对理论知识的内化程度并提高其实践能力,真正培养出高素质高技能型人才。     

城市轨道交通投资乘数效应计算的探讨

城市轨道交通作为城市投资最大的基础设施,存在一定的投资乘数效应。正确评估城市轨道交通产业的投资效应大小,有利于正确制定其发展策略。在分析城市轨道交通产业链的基础上,利用投入产出原理,探讨了城市轨道交通投资乘数的计算方法。并利用2002年中国投入产出流量表的数据,对提出的方法进行了示例计算,得到了城市轨道交通投资乘数为1．4073的计算结果。     

The New Zealand experience in restructuring road administration New Zealand road reform

Reform in the public sector in New Zealand saw the abolition of the Ministry of Works and Development in 1988, with the commercial activities being transferred into a Government owned company. Further reform saw the client function of roads transferred initially into the Ministry of Transport and then into an independent Crown agency known as Transit New Zealand. Transit New Zealand is led by an Authority of six members, appointed by the Government, and it administers the strategic (national) road network (10,500 kilometres).In 1996 a separate funding body, Transfund New Zealand, was established to distribute funds to Transit New Zealand and local authorities. Transfund New Zealand is funded through a share of the petrol excise, all vehicle registration and licensing fees and all road user charges (an axle-weight/distance charge levied on diesel vehicles, especially trucks). These revenues are paid into a dedicated National Roads Fund, which allows a measure of transparency in funding the road system. The reforms in New Zealand have resulted in large efficiency gains, with no measurable lowering in level of service.The road agency of the future is discussed, along with possible changes in road management.

Modal split in offshore supply network under the objective of emissions minimization

We study modal split under the objective of emissions minimization in the transportation of cargo from centralized vendors in the oil and gas industry to decentralized supply bases on the Norwegian coast. The supply network includes direct road transport and a sea route along the coast. To gain insight into modal split decisions between road and sea transport from the shipper’s perspective multi-period mixed integer optimization models are formulated. Particularly the models give possibilities to examine how weekly demand patterns at supply bases, cargo commitments to sea transport, storage possibilities at supply bases, and shipper’s responsibility for a certain share of vessel capacity may effect the emissions and the modal split. Experiments on real data from an oil and gas company operating offshore show that the size of the share of vessel capacity and the possibility for storage at supply bases are the major determinants for a larger shift to environmentally friendly sea transport. The models can be used as means for making decisions regarding how a shipper can commit to sea transport to achieve less emissions.
