围城内外--《伤逝》的启示

鲁迅的小说<伤逝>是表现知识分子生活思想最深刻、艺术最圆熟的一篇.它通过对涓生和子君从初恋、同居到最后分离的悲惨结局,反映了婚姻不仅仅是个人问题,还是社会问题;婚姻是项事业,需要人们去经营.而这两个问题到现在都还没过时,这就决定了<伤逝>不仅有一定的历史意义,同时还有很重要的现实意义.

论资本维持原则和公司资产的保护

在大陆法系法定资本制下,其实只存在资本真实缴纳和维持两原则,公司的资本和资产、资本的维持和资产的保护是始终紧密联系在一起的,资本维持原则的保护范围已延伸至公司整个资产。当出现公然或隐蔽的公司向股东的资本返还时,可产生一系列法律后果。     

基于信任的供应链伙伴关系维系管理方法研究

在契约的基础上进行基于信任的伙伴关系维系管理是保证节点企业间融洽合作关系的有效策略之一.本文首先分析了供应链伙伴关系管理实践中需要注意的问题以及信任与供应链伙伴关系的内在联系;在供应商开发程序的基础上融入信任诊断、协商沟通和改进供应链伙伴关系提高绩效的过程,提出了一种基于信任诊断的供应链伙伴关系开发程序进行多层伙伴关系维系的方法,包括基于信任的伙伴关系诊断层、伙伴关系协商沟通层和伙伴关系修正层.最后给出了支持该方法不同组成元素的企业实际运作例证.     

面向多样化需求的M RO 服务资源配置模型与算法

针对大型复杂企业维修任务集的多服务需求点和多样化需求特征,基于服务需求视角,定义一类多服务需求点下的MRO服务资源配置问题,建立以MRO服务提供商整体服务成本为优化目标,同时考虑资源紧张度、信任度和多服务需求点不同工期要求的问题模型;针对模型中的关键参数（即服务成本和资源紧张度）的特征进行分析,并给出相应的度量方法;在此基础上,设计改进的模拟植物生长算法实现求解,算法通过启发式获得初始可行解,并进行敏感性分析。研究结果表明, MRO服务资源配置模型和算法是可行和有效的,服务成本的波动、信任度和资源紧张度的变化对于资源配置结果均有影响,模型能够有效提高维修服务成本的估算能力,同时能够保持MRO服务提供商资源配置的稳定性。     

动态维修成本下的非周期预防性维修决策模型

为了制定更符合生产实际的设备预防性维修计划,将役龄回退因子和故障率递增因子相结合,根据设备的故障率及其可靠性来确定设备的维修间隔期,分析设备生命周期内的动态维修成本。维修成本包括非预期故障小修费用、预防性维修费用、设备停机造成的费用、设备预防性更换的费用,以这些成本最小化为目标,以设备有效度及设备可靠度为约束条件,建立非周期预防性维修决策模型并给出求解步骤,据此得到最优的预防性维修计划。     

Specificity of Performance Feedback in a Professional Service Delivery Setting

Although feedback is one of the most widely used intervention strategies, data on the specificity of effects has been sparse. The current study examined the effects of individualized public feedback on maintenance of client charts by therapists in a clinic setting. Four types of charting errors were tracked throughout the study. In Phase 1, feedback on two types of charting errors was provided and withdrawn in an ABA fashion. Phase II was a systematic replication of Phase I, using a second group of therapists, in which feedback was provided on the other two types of charting errors in an AB fashion. Results showed that feedback affected only those errors on which it was provided, thus supporting a specificity view of feedback effects. It is suggested that target behaviors be carefully selected and that generalization of feedback effects be assessed and not assumed.     

Tourist number prediction of historic buildings by singular spectrum analysis

A wooden historic building located in Tibet, China, experienced structural damage when subjected to tourists visit. This kind of ancient building attends to too many visitors every day because heritage sites never fail to attract tourists. There should be a balance between accepting the visitors and the protection of historic buildings considering the importance of the cultural relics. In this paper, the singular spectrum analysis (SSA) is used for forecasting the number of tourist for the building management to exercise maintenance measures to the structure. The analyzed results can be used to control the tourist flow to avoid excessive pedestrian loading on the structure. The relationship between the measured acceleration from the structure and the tourist number is firstly studied. The root-mean-square (RMS) value of the measured acceleration in the passage route of the tourist is selected for forecasting future tourist number. The forecasting results from different methods are compared. The SSA is found slightly outperforms the autoregressive integrated moving average model (ARIMA), the X-11-ARIMA model and the cubic spline extrapolation in terms of the RMS error, mean absolute error and mean absolute percentage error for long-term prediction, whereas the opposite is observed for short-term forecasting.     

北极环境问题研究综述

在全球气候变化中,北极环境变化最为明显,并开始影响全球生态系统。北极环境研究及维护日益引起国内外学术界的关注,有价值的研究成果大量涌现并呈现出三大特点:在研究角度上,多集中于海洋环境法制建设;在研究内容上,面上研究较多纵深挖掘甚少;研究针对性不强,强调理论而缺少可行性考虑;从研究方法上看,重视定性研究缺乏定量研究。未来的研究仍具有较大拓展空间,应在北极环境技术、数据交流、考察等多方面进行深入的研究并结合我国具体实际进行针对性的政策探究。采用综合定性与定量的研究方法。
