健美操动作的灵魂--论健美操音乐的选配

健美操的音乐是健美操动作的灵魂，音乐和动作的和谐统一是一套健美操完美表现的标志，因此音乐的选配对动作的节奏、风格、整体布局及表现起着决定性的作用。同时在选配健美掺音乐时我们应特别注意音乐的延续性和完垫巨，此外音乐的风格、节奏和旋律决定着健美操动作的编排及表演者的再创造。     

陕西秦岭旅游景区认知与选择偏好研究

在大尺度区域旅游规划兴起背景下,本研究以陕西省秦岭旅游发展专项规划为例,基于客源群体差异角度,运用认知度和偏好度等值线图对大区域旅游景区认知和选择偏好规律进行了探究,结果表明：①成熟型和稳定型旅游景区形成认高知度聚集区,成长型和开发型旅游景区形成低认知度分散区;②旅游景区选择偏好形成聚集区和辐射区,数量选择偏好存在差异,旅游景区空间显示偏好与交通通达性密切相关;③大区域旅游景区认知度和选择偏好度存在正相关关系,形成了以认知为基础的旅游景区偏好和出游倾向。     

县域生态工业园区发展路径选择

县域经济发展生态工业是循环经济的必然选择,生态工业园区是县域生态工业的主要载体。生态工业茵区有虚拟型、现有改造型和全新创建型三种建立模式。目前,县域经济构建生态工业园区存在物质集成障碍、技术障碍、信息共享障碍、效益障碍和政策障碍等障碍,因此需要进一步制度创新。     

Why are there proportionately more poor pupils enrolled in non-state schools in urban Kenya in spite of FPE policy?

One of the conundrums of free primary education (FPE) policy in several countries in Sub-Saharan Africa is the ‘mushrooming’ of fee-paying private schools. Several researchers have become interested in studying this phenomenon and have raised the question—does free primary education meet the needs of the poor? Emerging voices among this group of researchers suggest that the impact of FPE, particularly in meeting the educational needs of the poor may be over-stated in situations where the poor still utilize what is referred to as ‘private schools for the poor’. The concerns expressed by those voicing this point of view point to the question of why the poor choose fee-paying [low quality] private schools when there is, presumably a free state school? To respond to this question and to contribute to this debate, this paper adopts the excess demand and differentiated demand frameworks to analyse how slum (poor) and non-slum (non-poor) parents utilize education in Nairobi, Kenya following the implementation of free primary education policy in 2003. We conclude that the answer to the ‘mushrooming’ of private schools for the poor is ‘excess demand’. As to whether free primary education meets the needs of the poor, we argue that where supply does not match demand excess demand is likely to arise in the initial stages. We recommend that what is required is greater and possibly differentiated and better targeted investment in education whereby unequals are treated unequally in order for the Kenyan government not to under-invest in the education of the poor.     

理性选择理论视角下的身份认同研究

理性选择理论在社会学、公共行政和公共管理等领域产生了丰富的理论成果,其对个人行为选择的分析着重运用系统方法进行研究,以达到解释行为发生原因,预测行为前景的效果.这在个人确立身份并建构身份认同的过程中发挥了重要的指导作用,通过引导个人在差异申确定身份,从语言、文化、记忆等层面完成身份建构,避免个人因在身份认同上与群体的偏离而产生发展的滞后性,在思想上和行动上实现个人的身份认同,彰显人生的价值与意义.

选择连词"其"与语气副词"其"

选择连词"其"和语气副词"其",是古代汉语中极易混淆的两种虚词用法,在某些具体文献用例中,"其"字到底用作选择连词还是语气副词往往难以识别.作者试从二者的源流关系和它们的现代汉语译文等角度,分析造成二者难以识别的原因,并由此探求在具体文献用例中怎样进行识别的方法.

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.
