Competition and regulation in a new integrated transit system across jurisdictional borders

It is often argued lately that some regional transit systems should be integrated to improve the transit services across jurisdictional borders. One of the important issues concerning this integrated transit system is how to make proper use of the competition and regulation to improve its performance and to increase relevant benefits to the authorities, the operators and the passengers. This paper deals with this problem in a new integrated transit system across jurisdictional borders. An optimization model is used to investigate the competition of transit operators in oligopolistic competition transit market (OCTM). An optimization model with nonlinear complementarity constraints is proposed to guide the competition of transit operators using transit subsidy as the regulation means in system optimum transit system (SOTM). By analyzing and comparing the performances of the integrated transit system in two markets, numerical studies show that the competition mechanism should be made full use of and transit subsidy is an important regulation means that should be valued by the transit authorities in the integrated transit system.

‘Tool port’ to ‘landlord port’: a game theory approach to analyse gains from governance model transformation

This study investigates potential port users’ surplus and terminal operators’ profits due to transforming port governance from the ‘tool port’ model to the ‘landlord port’ model. Although the landlord port model is one of the most adopted and successful port governance models, many ports still operate under other models. Chittagong Port, the largest port in Bangladesh, currently operates under the tool port model, while the country’s second-largest port, Mongla Port, operates under the service port model. Chittagong Port is currently facing many challenges, including capacity expansion and renovation of port facilities. Therefore, we form four hypothetical situations for port governance model transformation, assuming that Chittagong Port will transform to the landlord port model but that Mongla Port will run under the existing governance model. Estimating a Bertrand game model, we present a cost-benefit analysis for port users and terminal operators (or port authorities) in hypothetical game situations. The results reveal that privatising one of the container terminals under a landlord setting is the most profitable scenario for Chittagong Port Authority, but privatising all terminals of Chittagong Port yields the highest users’ surplus. However, privatising two of the terminals while they cooperate yields the lowest users’ surplus.     

Technology application and development trend of intelligent unmanned system北大核心CSCD

Intelligent unmanned system combat is moving from concepts to actual combat applications. The military applications of intelligent unmanned systems are emphasized by focusing on the needs of the combat missions that they will undertake on future battlefields and summarizing the development statuses of land, air and maritime unmanned systems. Aiming at the key problems faced by intelligent unmanned systems and the practical difficulties that will be faced on the battlefield in the future, we analyze the key technologies required for intelligent unmanned systems, including autonomous perception and understanding in complex environments, behavioral decision-making and trajectory planning, autonomous navigation and positioning, multi-scenario autonomous skill learning and intelligent control, unmanned cluster cooperative control, natural human-computer interaction, etc. At the same time, aiming at the problems that will be encountered in the further development of intelligent unmanned systems on the battlefield in the future, we start with individual enhancement and cluster enhancement, and conduct a detailed analysis of the development trends of intelligent unmanned systems. © 2022 Palaeobulgarica.

提升新能源汽车专业服务地方产业发展能力的探索与实践

专业服务地方产业发展的能力是职业院校建校水平和人才培养质量的反映,随着河南省首张纯电动"牌照"落户三门峡,三门峡市新能源汽车产业对相关高技能专业人才培养提出了强劲需求,但是,目前职业院校还存在主动对接汽车支柱产业不足,汽车专业设置与产业需求脱节等问题。产教融合、校企合作的办学模式是职业教育改革的成功经验,地方职业院校应立足区域产业的转型发展,建立"岗位主导·项目带动"的人才培养模式,以汽车专业群建设为引领,从专业结构优化调整、人才规格紧贴行业、推进校企对接、加强专业课程改革力度、打造"双师型"教师队伍、推行校企"双主体"育人等方面入手,培养工业企业急需的高技能人才,助力工业转型发展。     

鲁迅"魏晋文学自觉说"辨正

鲁迅关于魏晋时代是"文学的自觉时代"的学术观点有自己独特的内涵.鲁迅在《魏晋风度及文章与药及酒之关系》中,肯定的是魏晋时代一批文人疏离或摆脱了重教化的实用主义文学观念,他们坚持"师心"、"使气"并在这个意义上获得自身"文"的独立思想品格和审美价值,这种意识的出现,就是鲁迅所说的"自觉".赵敏俐《"魏晋文学自觉说"反思》体现了他在今天与鲁迅当年不同的一种对传统文化的选择与阐释.
