职业体育联盟的反垄断规制 ——美国经历与中国立场

在梳理美国以往判决与理论的基础上,分析了美国法院的矛盾判决导致的大量不受规制的反竞争行为.职业体育联盟在功能上类似于合资企业,联盟内竞争与合作的结合恰是其他产业内合资企业的典型特征.虽然合资方(联盟的各运动队)能够在合资企业的范畴以外继续竞争,但离开了合作,任何合资(体育联盟)都不可能有效地运转.联盟像合资企业一样,不应当对提升产品效力的限制竞争措施承担反垄断责任.但联盟滥用其垄断力量,将限制竞争措施扩展至超过维持其生存能力之外的行为,应当受到反垄断法的规制.

Improving Academic Performance of Sport and Exercise Science Undergraduate Students in Gross Anatomy Using a Near-Peer Teaching Program

Peer and near-peer teaching programs are common in medical undergraduate courses. However, there are no studies that have investigated the effectiveness of a near-peer teaching program on the academic performance of undergraduate students pursuing sport and exercise science coursework. This study was conducted to analyze the effectiveness of such a program for students who participated in a course on the functional anatomy of the locomotor apparatus. A total of 39 student participants were divided into two groups: students in one group voluntarily attended at least one session of a near-peer teaching program, and students in the other group attended no sessions. The final grade (range 0–100%) was recorded and used as an indicator of academic performance. The final grade of students who attended the near-peer teaching program (69.5 ± 16.0%) was 38.7% higher (P = 0.002, d = 1.06) than those who did not (50.1 ± 20.4%). When the academic performance of the same students was evaluated in another course (exercise physiology) that did not offer a near-peer teaching program, there were no significant differences between the groups (students who attended or did not attend the near-peer teaching program). A significant positive association was found between near-peer teaching program frequency and the number of students approved and not approved in the course (P = 0.041). A significant difference (P = 0.001) was found in the attendance at regular classes between the group who participated in the near-peer teaching program (median: 62 hours; IQR [interquartile ranges]: 4.0 hours) and those who did not (median: 58 hours; IQR: 4.0 hours). Gender was not a moderating factor on academic performance or near-peer teaching program attendance. These results highlight the effectiveness of a near-peer teaching program on the academic performance of students from a sport and exercise science degree program while enrolled in an anatomy course.

从石油供需缺口论我国石油安全策略

我国石油生产形势比较严峻,今后产量只能保持稳中略有上升的势头。但随着国民经济持续、高速的发展,石油需求增长幅度较大,今后石油供需缺口占国内石油需求的比例将不断上升,预计2005年、2010年和2015年将分别为38.6%、46.0%和53.4%。为此,本文根据我国油气资源勘探现状、能源消费结构和经济发展等特点,对未来我国石油安全策略提出五条具体建议：立足国内,保障石油基本供应;大力发展天然气,以气代油,减轻国民经济发展对石油需求的压力;积极利用国际石油资源,弥补国内石油供应缺口,保证国民经济发展的需要;依靠科技进步,提高能源利用效率,实施可持续发展方针;建立国家石油战略储备,提高应对突发事件的能力。     

随机产出随机需求下的供应链协调问题研究

考虑随机产出随机需求下单供应商-单零售商的两级供应链系统,研究回购契约在双随机环境下协调供应链的作用,分别建立基于批发价格契约与回购契约的供应链分散决策模型,比较两种契约安排下的供应商定价、零售商订货决策以及供应链各方利润,揭示影响回购价格的关键因素,分析供应商产出波动、需求波动分别对供应商定价决策、零售商订货决策以及供应链各方利润的影响。研究表明,回购契约能有效协调随机产出随机需求下的供应链运作,且回购契约对供应链效率改善随着供应商产出波动的增加而提高。
