Optimization Model and Algorithm for Crew Management During Airline Irregular Operations

Airline irregular operations have long been a realm where human experience and judgement are the most important tools to utilize. Crew management during irregular operations is usually the bottleneck of the whole system-recovering process due to complicated crew schedules and restrictive crew legalities as well as the size and scope of the hub-and-spoke networks adopted by major carriers. A system-wide multi-commodity integer network flow model and a heuristic search algorithm for the above purpose are presented and discussed in this paper. The computational experiences show that the algorithm is efficient enough to solve problems of realistic size and also has the flexibility to accommodate practical business requirements.     

One-dimensional optimal bounded-shape partitions for Schur convex sum objective functions

Consider the problem of partitioning n nonnegative numbers into p parts, where part i can be assigned n_i numbers with n_i lying in a given range. The goal is to maximize a Schur convex function F whose ith argument is the sum of numbers assigned to part i. The shape of a partition is the vector consisting of the sizes of its parts, further, a shape (without referring to a particular partition) is a vector of nonnegative integers (n₁,..., n_p) which sum to n. A partition is called size-consecutive if there is a ranking of the parts which is consistent with their sizes, and all elements in a higher-ranked part exceed all elements in the lower-ranked part. We demonstrate that one can restrict attention to size-consecutive partitions with shapes that are nonmajorized, we study these shapes, bound their numbers and develop algorithms to enumerate them. Our study extends the analysis of a previous paper by Hwang and Rothblum which discussed the above problem assuming the existence of a majorizing shape.

许伯建及其书法述论

许伯建是现当代书坛一位颇有影响的书家,他对郭沫若"伪兰亭"观点曾进行深入辨析,认为"神龙本"更近唐初所存王羲之墨迹,并作出"神龙本"较"定武本"更近真迹的判断;在书学追求上,许主张"神韵出于真实",并以此作为自己攻书的基本原则;其晚年尤醉心于王氏名帖《兰亭集序》,对《兰亭》摹写着力最多,最终成就其雅韵精致的个人书风.许伯建还在传统诗歌创作方面有一定建树,其诗重真情韵致,与其书学重"神韵"的旨趣一脉相承,二者和谐相融、互为促进.     

宁波公共就业服务质量改善机制构建

向3000名宁波劳动者发放问卷对宁波公共就业服务质量进行调查,运用模糊综合评价法处理调查数据后发现,劳动者对宁波公共就业服务质量的总体评价是"中等".根据服务质量差距模型构建出宁波公共就业服务质量改善机制.为了提升宁波公共就业服务质量,宁波公共就业服务机构应正确理解劳动者对宁波公共就业服务质量的期望,正确选择公共就业服务设计和制定公共就业服务质量标准,确保按照公共就业服务质量标准提供服务,保证政府公共就业服务传递与承诺相一致.     

中国单身女性的困境: 多元交叉的社会压力和歧视

随着中国单身人口比例的上升,单身人群特别是单身女性群体受到了社会各个层面的关注。目前国内对单身女性的研究主要通过深度访谈来探讨单身未婚女性的身心和生活状态,缺乏系统的理论观照,且访谈样本又大都局限于大城市的中产阶层单身未婚女性,因而限制了研究成果的代表性。从交叉性理论出发,分析中国单身女性面临的宏观(儒家文化和人口调控压力)、中观(媒体的形象控制和代际压力)和微观(性别歧视、年龄歧视和单身歧视)的多元交叉压力和歧视,厘清目前单身女性所受到的压力和歧视,从不同阶层单身女性的需求出发,才能为她们提供切实有效的帮助,并有助于解决目前我国单身人口比例上升的问题,缓解人口老龄化的压力。     

大学化学实验课程中有效数字的记录

有效数字是大学化学实验课程的主要教学内容之一,是培养学生在课程中理解并在日常学习与工作中规范使用有效数字,提升其对有效数字与测定误差之间关系的认识水平,树立良好规范的数字记录习惯,具有十分重要的现实意义。论述介绍了目前大学化学实验教学中关于有效数字方面存在的主要问题,并采用相应的举措建立和完善了教学方案以利于更好地解决存在的问题。通过几个学期的教学实践发现新教学方案取得了初步的成效,同时严格按照有效数字的要求记录与计算数据也是培养学生具有严谨科学素养的一条重要途径。     

徐家围子断陷油气运移体系及成藏模式分析

在对含油气组合特征和成藏要素配置关系综合分析基础上，根据断陷盆地发育特征以及天然气藏形成的主控因素，重点分析了地震泵对油气纵向运移的影响，建立了该区油气藏成藏模式，本区发育的油气藏类型主要有构造气藏，岩性气藏和由构造、岩性二者共同控制作用的构造—岩性气藏、地层超覆油气藏以及基岩风化壳油气藏。徐家围子断陷两期构造运动进而形成了正反转构造，为油气提供了良好的构造圈闭及纵向疏导通道。沙河子组共经历了3 次生排烃高峰，第一次由于强烈的构造活动，没有聚集成藏，后两次在其他成藏要素的配合下，最终得以聚集成藏。     

Financial policy innovation for social change: a case study of China's green credit policy

Financial policy impacts on a range of social issues such as poverty alleviation, education, pollution control, etc. Making good use of financial policy and applying innovation to existing financial systems can generate positive outcomes for society. This article is to discuss the case of green credit policy in China. This policy was jointly announced in 2007 by financial and environmental regulators. According to this policy, banks were encouraged to give more loans to environmental friendly companies than to others. Such policy has made great progress, and it became a more formal document entitled ‘Green Credit Guideline’ in 2012. This guideline included a comprehensive definition on green credit and specified several requirements at practical levels. Despite the great success, challenges of implementing such policy still remain. First, information about corporate environmental performance is insufficient; second, market incentives for green credit policy are not high enough; third, most banking staff lack knowledge and capacity to handle environmental affairs. Nevertheless, this case still sheds light on how financial policy innovation drives social changes. The key is to identify the connection between social issues and financial issues, and then to make a business case that creates pressures or incentives for financial institutions. This requires a market where social and environmental cost is appropriately priced and internalized to those who generate it. Ideally, financial policies should help shape such a market so that society can share values created by financial institutions.
