A survey of work done by the China family planning association

The China Family Planning Association was set up in May 1980 as a nongovernmental organization under the leadership of the Communist Party of China. Funds come from the government, international organizations, and individual or community donations. 13 branches have been established so far. The Association has contributed to publicity, education, and research: members have given lectures on family planning, genetics, and population theory, and have helped develop contraceptives. The lectures on population problems have been published. In addition, the Association's periodical "Ren Sheng" is published bimonthly, and has a circulation of 125,000. Meeting have been convened for the exchange of information and experience among family planning workers. The Association organized tripartite seminars with IPPF and JOICFP in June and October, 1983. Under the auspices of the Association, 8 trainees have been sent to the David Owen Center in the United Kingdom for a Year's study, and 1 trainee was sent to the London School of Hygiene and Tropical Medicine. The Association was accepted as a full member of the IPPF at the conference held in Nairobi, Kenya, in November, 1983.

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.

食品老字号品牌在来华留学生中的传播效果研究——以北京市为例

随着经济全球化的加速,食品老字号品牌应重视国际消费者,制定品牌发展的国际化战略,走出国门,重塑品牌形象.本文以北京市为例,通过对来华留学生这一群体展开调查,评估北京食品老字号品牌在来华留学生中的传播效果,调查发现北京食品老字号品牌在来华留学生中品牌知晓度和满意度都不高.如何充分利用来华留学生在华期间制定具有针对性的且行之有效的品牌传播策略,如何开展国际化品牌传播战略是北京食品老字号品牌想要提高知名度,走向国际市场亟待解决的问题.     

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.     

机关事业单位职业年金替代率研究

鉴于职业年金计划能够低成本、高效率地解决养老保险改革造成的待遇下降问题,且多国已从中收益,中国也将其作为促进机关事业单位养老保险改革的必需工具,国办发[2015]18号文件就要求职业年金制度应于2014年10月初确立实施.但是由于机关事业单位职业年金计划执行年限较短,一系列相关问题开始显现,如保障水平略低、收益渠道受限、配套措施缺失等.为此,建议及时采取灵活选取参保方式、开放创新投资手段、完善配套规定等措施来促进职业年金顺利发挥自身优势.     

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。
