依托中心城市谋求互惠多赢

随着国家振兴东北老工业基地战略的实施,以沈阳为中心的辽宁中部城市群正面临着千载难逢的重大发展机遇,各城市之间的经济联系、产业关联度日益密切,中部城市群区域合作和崛起趋势日渐明显。抚顺作为七城市中的一员,积极主动融入沈阳经济区,实现资源共享、优势互补、互惠多赢。在这些方面,抚顺具有得天独厚的条件和优势。在区位上,抚顺与沈阳趋于零距离,山同脉、水同源,两市中心距离仅45公里,边缘距离不足10公里,抚顺经济开发区与沈阳浑南新区一水之隔,而且随着对外开放程度的提高,这一两市结合部有望形成规模庞大的新经济区。在交通上,沈抚…     

夷务与商务——以广州口岸毛皮禁运事件为例

1791～1792年广州口岸的毛皮禁运事件不是由单纯的商务纠纷所引发的,它涉及到了中俄间的政治冲突。广州与恰克图两个口岸相隔万里,却互相牵连。由清廷、地方官员及外国商人对这一事件的态度,我们可以看到清朝的夷务管理与对外贸易间的关系,外贸在相当的程度上是为政治所制约的。清朝的夷务管理政策已逐渐与实际的需要脱节。     

电声乐队的建构与现代信息装备的资源开发

电声乐队依据以下几个方面来建构 :1 必须配有擅长演奏曲调的旋律性乐器 ;2 应配有足量的和声节奏乐器 ;3 乐队组合中不能缺少低音声部、旋律、和声节奏、低音这三方面是电声乐队必须具有的三个主要功能 ,缺一不可。MIDI的产生、电脑音乐系统的运用 ,使电声乐队具有了更为广阔的前景

论应用型本科人才及其培养

由本科教育培养的应用型人才称为应用型本科人才。应用型本科人才是客观存在的,且已有一定的发展历史。培养应用型本科人才是社会发展的要求,是高等教育大众化的要求。应用型本科人才的培养要树立相应的教育教学思想观念,要落实为企业服务的办学理念,要系统改革教学内容和教学方法,要积极推进产学结合,强化学生动手能力培养。     

自我网络特征对电信客户流失的影响

近年来,随着移动通信行业的蓬勃发展,市场饱和度越来越高,企业获取新用户的成本也越来越大。随着中国三大运营商竞争的加剧,产品和服务的同质化程度也越来越高,这使企业在老客户的保留上变得异常困难,客户流失率也在逐年上升,如何识别高风险流失客户并有效防止客户流失已经成为该行业管理者普遍关心的问题之一。 着眼于客户流失影响因素研究,运用社交网络分析方法,通过构造与网络结构相关的变量进行影响因素的探讨,运用逻辑回归方法构建客户流失预警模型。从社交网络的视角出发,利用客户的通话详单数据建立客户之间的通信网络,在自我网络的相关理论框架下,构建个体的度、联系强度、个体的信息熵3个自我网络特征变量。运用中国某移动运营商公司的月度客户数据(包括基础通信数据和通话详单数据),通过逻辑回归构建基于社交网络变量的客户流失预警模型。 研究结果表明,个体的度、联系的强度和个体的信息熵都对预测客户流失有显著效果。具体的,个体的度越大,联系强度越强,个体的信息熵越大,客户越不容易流失。外样本AUC值平均可以达到0.75以上,模型具有良好的预测精度。 研究结果对企业实践具有非常重要的意义,合作企业应用客户流失预警模型进行高风险流失客户的识别,预测精度可以达到70%,达到了企业的实践预期。客户流失预警模型可以帮助企业提前识别高风险流失客户,极大地降低企业维系客户的成本。建议企业管理者在未来更加关注与客户社交网络有关的变量,从网络结构的视角理解消费者行为,更好地进行客户关系管理。     

旧题王昌龄《诗格》臆说

《诗格》二卷的分离,在考据之外,有更深层的理论意义。通过《诗格》卷上与《河岳英灵集》的选诗及《诗式》的理论倾向之比较;通过《诗格》卷下与《诗式》的意境理论及晚唐五代诗格的理论传承之比较,可以确认《诗格》二卷分离后各自的理论背景及合视之所呈现的唐代诗格发展的轨迹。     

Child Poverty in Rural China: Multidimensional Perspective

This paper describes a pilot study on child multidimensional poverty in rural China by introducing the Alkire–Foster method based on survey data collected from five provinces/autonomous regions. Results showed that the headcount ratio of child multidimensional poverty was 14.29%. On average, multidimensionally poor children were deprived in 37.62% of all the dimensions, and their adjusted headcount ratio (multidimensional poverty) index was 0.054. Health was the most deprived dimension, followed by the subsistence and participation dimensions. Disabled children, children influenced by HIV/AIDS, and ethnic minority children were severely deprived. This study not only adds to the current literature on child poverty in China, but also provides policy suggestions for future action plans.     

Comparing MCDA Aggregation Methods in Constructing Composite Indicators Using the Shannon-Spearman Measure

Composite indicators have been increasingly recognized as a useful tool for performance monitoring, benchmarking comparisons and public communication in a wide range of fields. The usefulness of a composite indicator depends heavily on the underlying data aggregation scheme where multiple criteria decision analysis (MCDA) is commonly used. A problem in this application is the determination of an appropriate MCDA aggregation method. Of the many criteria for comparing MCDA methods, the Shannon-Spearman measure (SSM) is one that compares alternative MCDA aggregation methods in constructing composite indicators based on the information loss concept. This paper assesses the effectiveness of the SSM using Monte Carlo approach-based uncertain analysis and variance-based sensitivity analysis techniques. It is found that most of the variation in the SSM arises from the uncertainty in choosing an aggregation method. Therefore, the SSM can be considered as an effective measure for comparing MCDA aggregation methods in constructing composite indicators. We also use the SSM to evaluate five MCDA aggregation methods in constructing composite indicators and present the findings.     

On the Emotional Context Theory of the Mass Art Transmission

Concern of emotion and emotional motivation are the basis of language and literature context, and it is also the basis for the social domain of discourse related to the human culture. The traditional Chinese literature and the modern literature are both the carrier and manifestation of the mass emotional context. Besides, emotional context is also the one and only culture route and popularization route of the national revival. Emotional context shoulders the responsibility of literature and the value of critical comments.
