民办高校体育场馆BCO运营模式的探析

运用文献资料法、访问调查法、数理统计法,对河南省14所民办高校的体育场馆现状及运营模式进行了调查分析,结果表明：体育场馆资源严重缺乏、体育场馆运营模式滞后是民办高校体育场馆存在的主要问题;BCO运营模式能较好地解决民办高校体育场馆运营的问题,即在学校投资的基础上,加大企业的投资、坚持科学定位,前瞻考虑体育场馆的综合利用、实施管教分离,创新场馆的管理体制、实施两权分离,创新场馆的运营模式.

Fuzzy-based risk prioritization for a hydrogen refueling facility in Malaysia

Hydrogen is starting to be mentioned as an alternative fuel to replace the fossil fuel in future transportation applica- tions due to its characteristics of zero greenhouse gas emission and high energy efficiency. Before hydrogen fuel and its facilities can be introduced to the public, relevant safety issues and its hazards must be assessed in order to avoid any chance of injury or loss. While a traditional risk assessment has difficulty in prioritizing the risk of failure modes, this paper proposes a new fuzzy-based risk evaluation technique which uses fuzzy value to prioritize the risk of various scenarios. In this study, the final risk of each failure modes was prioritized by using the MATLAB fuzzy logic tool box with a combination of two assessments. The first assessment was concerned with the criteria which affected the actual probability of occurrence. This assessment considered the availability of the standard that was applied to prevent the likelihood of the scenario occurring. On the other hand, the second assessment was focused on evaluating the consequence of the failure by taking into account the availability of detection and the complexity of the failure rather than only the severity of the scenarios. A total of 87 failure scenarios were identified using failure modes and effect analysis （FMEA） procedures on hydrogen refueling station models. Fuzzy-based assessments were performed through risk prioritizing various failure scenarios with a fuzzy value （0 to 1） and risk level （low, medium, and high） while a tra- ditional risk assessment approach presented the risks only in forms of level （low, medium, and/or high）. Availability of the fuzzy value enabled further prioritizing on the risk results that fell in the same level of risk. This study concluded that fuzzy-based risk evaluation is able to further prioritize the decisions when compared with a traditional risk assessment method.     

The Dark Side of Collection Management: Deselecting Serials from a Research Library's Storage Facility Using WorldCat Collection Analysis

To address the situation of its nearly full storage facility, the Purdue University Libraries developed guidelines for the deselection of very low–use serial titles and conducted a pilot project to identify material for withdrawal. The library school intern hired to conduct the pilot used WorldCat Collection Analysis to create subject lists of titles to be considered for withdrawal. These lists also contained value-added information about how many benchmark institutions owned and duplicated the local holdings of each title. Working with subject specialists, the intern developed criteria to guide a major serials deselection project. After the success of the internship in six subject areas, the libraries funded a longer-term position to complete the deselection project.     

燃烧加热污染空气对超燃冲压发动机性能影响研究

针对燃烧加热地面试验设备存在的工质污染问题,采用数值模拟方法研究了燃烧加热污染空气对氢燃料超燃冲压发动机性能的影响。以飞行马赫数Ma=6.5,当量油气比ER=0.6为计算基准状态,分别对纯净空气和污染空气来流下氢燃料超燃冲压发动机的整机流场和性能进行了对比计算分析。燃烧化学反应模拟采用了改进的H₂/O₂七组分八方程模型,湍流模型为标准的 k-ε模型,并采用直连式燃烧室试验数据进行了数值方法的验证。研究结果表明:(1)相对于纯净空气来流,污染空气来流下的超燃冲压发动机推力和比冲均有所下降。(2)采用酒精燃烧加热器的前提下,来流参数匹配静温、静压、马赫数时,发动机性能与纯净空气来流下的结果最为接近,而匹配总温、总压、马赫数时相差最大。(3)来流参数匹配总焓、静压、马赫数的前提下,采用氢燃烧加热器时发动机性能与纯净空气来流下的结果最为接近,而采用甲烷燃烧加热器时相差最大。      

小城镇体育 大社会问题——来自我国小城镇学校体育的调查报告

采用问卷、面访、个案调查以及文献等方法对我国东中西3个不同区域的16个小城镇学校体育的软件、硬件和学校课外活动运动训练等方面的现状和发展进行了深入的研究和探讨.研究发现部分小城镇中小学已经具有相当的体育硬件设施,条件较为完备的体育馆、塑胶田径场以及其他常见体育活动场地在发达地区中小学为数不少,但中西部仍有较大的差距;学校体育硬件设施质量高低和数量多寡基本与地区经济发展水平成正比,硬件设施差距随经济发展逐渐扩大;研究认为目前的教育体制和办学指导思想使小城镇学生身体健康和学业有所失衡,体育与文化学习的关系仍有待于进一步理顺.     

大型公共体育设施国民经济评价研究(Ⅰ)——概念性框架与评价方法

国民经济评价作为建设项目投资决策的重要依据,可使决策更加科学、规范和高效,避免或减少投资失误。当代中国大型公共体育设施建设项目国民经济评价相关研究基本处于空白状态。以逻辑顺序为依据,采用层层推进的方法,对"大型"、"公共性"、"国民经济评价"、"大型公共体育设施国民经济评价"作出界定,形成崭新的概念性框架。针对体育设施的属性,通过对费用——效果、费用——效益等传统国民经济评价方法的梳理、总结、剖析,提出了"综合效益——净投资"具有较好适用性的大型公共体育设施国民经济评价方法。
