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.

物资采购综合评价指标体系质量控制模型应用研究

本文依据非序列多层次目标准则建立了物资采购综合评价指标体系,应用模型参考思想构建了物资采购综合评价指标体系的质量控制模型及其目标函数,按照采购项目管理的运作程序对各个阶段的采购质量做了相应的评价,最后运用实例对以上讨论进行了定量化的分析。通过计算得到的数量指标,我们可以有效评价和控制物资采购工作,以期提高采购质量、节省经费开支。     

卧式吸尘器包装结构有限元研究

为了验证卧式尘袋吸尘器包装结构的安全性能,根据该吸尘器生产、物流过程中所处物流环境,采用Creo软件建模,通过施加相应约束条件, 分析卧式吸尘器包装件在物流环境中抗压、随机振动、跌落等情况,采用ANSYS Workbench软件分析包装件在相应载荷作用下的应力、变形以及物理试验下包装 、产品受损情况。结果表明卧式吸尘器包装件在最大堆码情况下,变形量未超过标准规定10 mm;经过模态分析,得到6阶模态参数表明不会发生共振现象;包装 件跌落试验结果表明应力应变较小。该吸尘器包装结构设计满足抗压、随机振动、以及跌落测试等要求,方案可行。     

夫妻一方举债案件中的当事人确定和嗣后救济

“夫妻共同债务”与 “连带债务”在债务发生原因和债务履行上存在差别,对其进行诉讼时,诉讼形式应为固有的必要共同诉讼。当债权人仅起诉名义举债人一方时,可能构成诉讼被告不适格。借鉴德日诉讼要件理论,法院可以对当事人适格问题进行“职权调查”,但所采用的诉讼资料应遵循“辩论主义”。在此基础之上,应明确法院的释明权适用情形,即通过对已经参加诉讼的当事人进行释明来改变诉的不合法状态。若因法院在此审判阶段释明权适用不到位,而最终不合法的诉获得了无法顺利执行的实体判决,债权人想要获得圆满救济仅能依靠再审。     

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.     

基于累积前景理论的多资产投资组合优化与实证研究

基于CPT视角的多风险资产投资组合模型,探讨投资者面对不同投资风险时的心理变化以及心理变化对其投资策略的影响。通过选取不同超额收益率及波动率水平的股票,测试投资策略对于风险态度指标的敏感度。研究表明,投资者面对不同风险具有明显地心理变化,并且其心理变化对投资策略具有显著的影响。具体表现在几个方面：投资者面对不确定收益时,表现出风险厌恶,面对不确定损失时,表现出风险偏好;投资者将无风险资产的投资收益作为心理参考点,所做的投资决策与相对于此参考点的相对财富水平的变化有关,而不是与传统理论中的绝对财富变化量相关。     

债券增信对企业创新的影响研究

债券增信能帮助企业以更好的条件发行债券,因而对企业的创新能力产生影响。通过对2007-2015年上市债券的研究发现：债券增信能够显著提升企业创新能力,但不同的增信方式（第三方保证、抵押和质押）其影响存在差异,其中,以采用抵押担保的增信方式效果为最佳;并且,债券增信对企业创新的提升效果在融资约束企业更为明显,从另一侧面证明了融资约束对企业创新的负面影响。
