论构建和谐社会的历史必然性

当前我国正处于“黄金发展期”与“矛盾凸显期”并存的关键阶段,构建社会主义和谐社会是我国社会发展目标的准确定位,是顺应历史发展趋势的正确选择。它既传承历史,又开创未来,同时又对马克思关于“自由人联合体”的论述做出了时代性的阐释。     

既定增长目标下的产业结构调整--以安徽省为例的实证分析

文章按照安徽省近期经济增长目标,通过对1978年以来的数据进行分析,回归三次产业的生产函数,来预测未来产业结构中的各项指标比重.并针对经济增长中所存在的农业人口比重过大、就业结构调整方向错位、转换缓慢;投资率长期偏低,投资增长缓慢、结构不合理;规模经济效益低下,产业竞争力相对较弱等主要问题进行分析,提出了相关的政策建议.     

区分关键路径与非关键路径的项目进度偏差分析模型

挣值管理法是项目成本和进度控制中应用比较广泛的一种方法。文章分析了传统挣值进度偏差分析的缺点,提出了区分关键路径与非关键路径的进度偏差分析方法。分别探讨了关键路径和非关键路径的进度偏差。在各级施工单元计划编制的基础上,引入挣得时间ET（Earned Time）原理,建立整个项目的进度偏差分析模型。该方法可以精确地分析项目的进度偏差情况和偏差来源。     

家族涉入、家族理性与家族企业目标偏好——基于一项比较案例的探索

家族涉入是家族企业的基本特征,它影响了家族社会资本的结构分布,进而决定了家族理性的效用构成,并通过对家族企业二元目标的不同偏好表现出来。其中,家族理性反映为家族企业对家族整体责任的兼顾,二元目标指的是对企业即期利润的追求以及对家族非货币化利益的追求。这种家族涉入决定家族理性,家族理性体现家族企业目标偏好的理论构念,通过一项比较案例分析得以验证。案例中的两家家族企业背景相似,但由于企业传承上的不同选择影响了家族涉入情况,进而两家企业表现出显著的经营目标差异。     

我国货币政策传导机制及盯住目标选择

本文通过建立结构向量自回归模型,分析了货币政策不同盯住目标与最终目标之间的作用关系和扰动响应,对货币政策数量、价格两种传导机制的有效性进行了比较。从实证结果看,中央银行选择盯住货币供应量具有相对合理性。中央银行应继续完善货币政策体系,疏通货币政策传导渠道,更好地实施以货币供应量为盯住目标的数量调控。     

Customer complaint behaviour (CCB) in the retail sector: why do customers voice their complaints on Facebook?

With the increasing usage of platforms such as Facebook, understanding customer complaint behaviour (CCB) in the context of the social media is imperative for any businesses. Of the two billion users on Facebook, more than half of its users have shared their product-related experiences with others on the platform. This paper aims to explore CCB in the context of social media in regards to customers’ unfavourable buying experiences in the retail sector. A qualitative research approach and 12 in-depth interviews were conducted. The findings indicate that the respondents’ initial contact with the retailer directly resulted in service recovery failures and undesirable outcomes. Such double deviation then leads to frustration and uncertainty of the situation, which furthermore led to the respondents’ need to voice their complaint by sharing their unfavourable experiences on Facebook. The main reasons for the respondents to voice their complaints on the platform is to vent frustration, to share their unfavourable experiences, a need to be seen, understood and respected, to seek revenge by damaging the retailer’s reputation as well as offering the retailer a chance to improve. A proper way to manage complaints, in which frontline employees can solve the problem before the customers feel the need to turn to the social media, is crucial. However, once the complaints are voiced on Facebook, it is imperative to respond to the complaints and acknowledge the problem rather than ignoring the situation.     

深度复极限学习机在雷达HRRP目标识别中的应用

传统雷达高分辨一维距离像(High-resolution Range Profile,HRRP)目标识别方法只利用目标幅度信息而丢失其相位信息,这势必会造成信息不完备。为解决此问题,提出将深度极限学习机从实数域扩展到复数域,以有效提取复HRRP序列的深层潜在结构信息。同时为更好地保持数据间的邻域信息,将流形正则化引入到网络模型训练过程中,提出流形正则深度复极限学习机。在雷达暗室测量数据上的实验结果表明,所提算法相比常用的深度学习模型具有更好的识别效果和更快的训练速度,验证了算法的有效性。     

小型化高频地波雷达舰船目标检测方法

针对OSMAR2003型小型化高频地波雷达系统的目标检测问题,讨论了对小型化高频地波雷达系统低信杂比回波信号的优化处理过程,给出了一种峰值检测后同时在距离域、多普勒域和波束域进行联合的三维联合恒虚警(CFAR)目标检测方法,利用高分辨力测向算法对检测到的目标进行方位估计,然后利用最邻近法进行目标关联得到目标点航迹,最后结合小型化高频地波超视距雷达的实测数据验证了三维CFAR检测器的有效性。     

An empirical study on the timing of big retailers’ initial internationalization: Influence of the target market and entry-mode choice

This paper examines the timing of big retailers’ initial internationalization and proposes a theoretical framework. Then, the framework is tested with the proportional hazard model and data of European and U.S. big retailers. Empirical results show that retailers’ entry timing is jointly influenced by the economic conditions of both the home market and target foreign markets, cultural and geographical distance, and the entry mode. Based on these findings, this article offers suggestions to China’s big retailers whose initial internationalization has just started.     

房地产供应链成本控制体系构建分析

供应链环境下,传统的房地产成本控制体系发生了重大变化。分析房地产供应链成本的概念、构成及房地产供应链的结构模型,构建房地产供应链的成本控制体系。成本控制体系始于成本核算体系,终于成本优化体系,包括主体、对象、方法、目标等要素;成本控制方法是成本控制体系的核心内容,目标成本法不失为一种有效的控制方法;供应链环境下各种理论方法日渐成熟,应注重房地产供应链成本控制方法的集成和扩展。
