工程信息技术与选线设计课程体系的融合

工程信息技术是把计算机信息技术应用于工程规划、勘测、设计、管理中而发展起来的一门交叉科学技术。而铁路选线设计则是一个集信息采集、信息处理、信息识别、信息利用和信息管理于一体的综合设计过程。在选线设计课程建设中,应在课程教学、课程设计、毕业设计各个阶段将工程信息技术与选线设计课程的内容进行融合,改革选线设计课程体系和教学内容;将计算机图形技术、虚拟现实技术、建模技术和仿真技术与铁路选线理论相融合,以完善现代选线设计理论和技术。

从“感情的型”看李长之的传记批评

在李长之的批评实践中,传记批评分量最重、最具影响。李长之的传记批评具有鲜明的个人风格和独特的美学追求,他以“感情的型”为文艺创作的最高标准,通过“感情的型”沟通作家人格和作品风格,进而达到审美教育的目的。李长之传记批评中蕴含的审美教育理念,是在中国儒家哲学和德国浪漫主义的双重影响下形成的。     

National identity and regional development: Cornwall and the campaign for Objective 1 funding

The politics of identity is important within regional and governance policy debates, becoming a mechanism for ‘filling in’ the democratic gaps left by the hollowing out of the state, with much discourse about constructing identities for governance purposes. This raises questions about the feasibility of processes of identity construction, and whether it starts from new, or builds on existing identities. We use the case study of the Cornish campaign for Objective 1 EU structural funding, engaging directly with modernist versus ethnosymbolist accounts of nationalism, to explore the binary between instrumental, constructed identities and more phenomenological accounts.

高校科研经费管理的现状、原因及对策

伴随着政府对高校科研经费投入的日益增加,如何科学而又合理地用好科研经费,是我国高校财务管理工作面临的新挑战。近年来,我国高校科研经费管理在立项、预算、使用和考核等方面都存在着诸多问题,在科研经费的使用过程中违规违纪现象尤其严重,这些现状背后的深层次动因有信息不对称、管理体制中存在矛盾等。对高校科研经费的管理应采取健全管理制度、合理预算、加强监管等改进措施,以提高高校科研经费的使用效益。     

System Transformation and Development Path on Medical Care

China's basic medical care system has achieved universal coverage, faced the system transformation with substance fair. Under the transformation background from universal coverage to integration on urban and rural areas, and the transformation direction from the "medical care" to "health for all", through the institutional transition path on system design, service delivery, fi nancial support, this paper points out that how to improve quality of medical care and optimizing the level of health care services, match sustainable funding system and improving payment system, which in public health, medical services, medical care and medicine supply, realize the transformation and the development from universal medical care to health care.     

Pricing and Operational Performance in Discretionary Services

In many services, for example, website or landscape design, the value or quality derived by a customer depends upon the service time, and this valuation differs across customers. Customers procure the service based on the expected value to be delivered, prices charged, and the timeliness of service. We investigate the performance of the optimal pricing scheme as well as two commonly used pricing schemes (fixed fee and time‐based pricing) for such services on important dimensions such as revenue, demand served, and utilization. We propose a novel model that captures the above features and wherein both service rate and demand are endogenous and functions of the pricing scheme. In particular, service time is an outcome of the pricing scheme adopted and the heterogeneous valuations of customers, unlike in the queueing‐based pricing literature. We find that the service system may benefit from a greater variance in consumer valuations, and the performance of pricing schemes is impacted by the shape of the distribution of customers' valuation of service time and the responsiveness desired by customers. Both the fixed fee and time‐based schemes do well relative to the optimal pricing scheme in terms of revenue in many plausible scenarios, but there are substantial differences between the pricing schemes in some important operational metrics. For instance, the fixed fee scheme serves more customers and has higher utilization than the time‐based scheme. We also explore variants of the fixed and time‐based schemes that have better revenue performance and show that the two‐part tariff which is a combination of fixed and time‐based pricing can do as well as the optimal scheme in terms of revenue.
