Application of online booking data to hotel revenue management

This paper presents an application of online booking data, comprised of big data crawled from a hotel booking website to hotel revenue management. It is important to build a quantitative revenue management method for online hotel booking systems incorporating overbooking strategies, because of increasing numbers of bookings through online booking websites and last-minute cancellations, which cause serious damage to hotel management. We construct a quantitative overbooking model for online booking systems combined with customers’ choice behaviors estimated from the data. Firstly, we present the overbooking model for online booking systems. Secondly, we estimate the choice behaviors of the customers from the online booking data by a discrete choice model. Thirdly, combining the estimated discrete choice model with the theoretical overbooking model, we investigate the expected sales maximization problem where we numerically solve the optimal overbooking level and room charge. Finally, we provide numerical examples of the optimal overbooking strategies and room charges using online booking data of two major luxury hotels in Shinjuku ward, Tokyo. This method, which utilizes online booking data available by crawling from booking websites, helps hotels obtain an optimal room charge and overbooking level maximizing the expected sales.     

高校图书馆基于区域图书馆联盟开展阅读推广的探讨

目前,高校图书馆阅读推广活动受到广泛重视,高校图书馆合作开展阅读推广活动的意识较强,并且阅读服务项目的类型多样。但是高校图书馆存在阅读推广活动呈现阶段性、读者对于阅读推广活动的参与度不一、阅读推广活动面向的读者类型较单一、缺乏阅读推广活动的评价机制等问题。我国高校图书馆基于区域图书馆联盟开展阅读推广活动时应该成立联盟阅读推广委员会,制订联盟阅读推广制度,建立阅读推广的评价体系,合作开展阅读推广活动。

The contribution of orthographic and phonological processes to word reading in young Norwegian readers

The dissociation between phonological and orthographic processes in word reading was investigated in a study involving 147 children in grade 3. The criterion measure was a timed word reading test. Two tasks assessed phonological skills and two tasks assessed orthographical skills. Orthographic ability accounted for variance in word reading even after phonological ability had been controlled. Poor readers differed from skilled readers in the way phonological and orthographic factors were balanced. The relationship between the two factors was fairly strong among poor readers, whereas the correlation was low for more skilled readers. Furthermore, phonological factors played a much stronger role in explaining the variance in word reading among poor readers, while on the other hand, orthographic factors were more powerful among skilled readers.     

谈开放性语文阅读教学

语文阅读教学要摆脱封闭性,实现开放性。实现语文阅读教学课堂的开放性,应当建立“大语文”观念,同时还要求对问题的解决应持开放的态度,要求教师应具有开放的胸襟。语文阅读教学倚重开放性,但并不意味着教师可以对学生的课堂行为放任自流。
