据统计,我国高校每年立项的科研项目数量在逐渐提高,这就说明高校的科研水平也在逐步提高。而科研经费一直是困扰大多数高校的难题,如存在支出不合理等问题,使得部分科研经费并没有发挥应有的作用。因此,本文主要探究高校科研经费的使用和管理问题。 相似文献

商事侵权是商业交易中的侵权行为。商事侵权行为是指在商事活动中,行为人违反法定的或交易习惯上的注意义务侵害他人权利和法益的行为。商事侵权责任法并不是独立于传统民商法的独立法律部门,而是私法的重要组成部分。可以普通的商事侵权行为和特殊领域的商事侵权行为划分为基本框架,确定商事侵权行为的类型。普通的商事侵权行为以侵害的客体为划分标准,包括侵害商事人格权、侵害物权、侵害债权、侵害知识产权和侵害营业权等侵权行为,特殊领域的商事侵权行为则包括公司侵权、证券侵权、产品质量责任、商事欺诈侵权、竞业禁止侵权和侵害消费者权益等无法完全归入普通商事侵权的侵权行为。 相似文献

In airline networks, a link creates profits for its carrier in conjunction with the carrier’s other links. In other words, a link has “network” value. One prominent mechanism behind this network value is a hubbing effect: adding one single link to a hub creates many connecting routes. This paper studies a different and less explored mechanism of network value. It relies on the observation that passengers generally prefer a higher flight frequency (mainly because it provides more flexible options for travel times). Specifically, when a carrier adds a link, the created connecting routes will increase the traffic densities on adjacent links. As the carrier raises flight frequencies to meet the higher densities, there creates a positive effect on demand. By structurally estimating a model that incorporates this mechanism, I am able to quantify the density effect. It is found to be about 3.8 times as large as the hubbing effect. Furthermore, the model shows that the competitive impact of an airline entry (i.e., adding a new link) goes greatly beyond the local city-pair market where the entry happens. 相似文献
