Identification of average marginal effects under misspecification when covariates are normal

A previously known result in the econometrics literature is that when covariates of an underlying data generating process are jointly normally distributed, estimates from a nonlinear model that is misspecified as linear can be interpreted as average marginal effects. This has been shown for models with exogenous covariates and separability between covariates and errors. In this paper, we extend this identification result to a variety of more general cases, in particular for combinations of separable and nonseparable models under both exogeneity and endogeneity. So long as the underlying model belongs to one of these large classes of data generating processes, our results show that nothing else must be known about the true DGP—beyond normality of observable data, a testable assumption—in order for linear estimators to be interpretable as average marginal effects. We use simulation to explore the performance of these estimators using a misspecified linear model and show they perform well when the data are normal but can perform poorly when this is not the case.     

中国与海合会国家金融合作的问题及对策分析

近年来,中国与海合会国家的金融合作形式日益多元,同时也取得了一定成果并积累了宝贵经验,为双方进一步开展金融合作打下了坚实基础。当前,中国与海合会国家的金融合作深度有限,具体表现为金融合作规模增长缓慢,互设金融机构数量不足,合作水平参差不齐、层次不高,平台作用不足等问题。本文从政治环境、金融体系、文化认同等方面分析影响中国与海合会国家金融合作的主要因素,并提出从政治评估、战略对接、货币结算、文化认同等方面进一步提升中国与海合会国家金融合作水平的应对策略。     

Development of an RFID‐based Traceability System: Experiences and Lessons Learned from an Aircraft Engineering Company

This paper presents a case study of the research and development of an RFID‐based traceability system in an aircraft engineering company in Hong Kong. We report the system design and implementation, and discuss our experiences and lessons learned. The aim of the RFID system is to effectively support the tracking and tracing of aeroplane repairable items in the company. The study reveals eight critical success factors for the successful implementation of RFID systems, namely, create strong internal and external motivation for improvement, stir up desire to keep abreast of the latest technology for global competitiveness, strive for cross organizational implementation, avoid major process changes/limit process changes, start with a small RFID project scope, facilitate equipment vendor's investment, use cost‐effectiveness reusable tags, and transfer RFID skills and knowledge from university to industry. We also summarize 13 lessons learned, including three lessons concerning RFID implementation at strategic level, six lessons at management level, and four lessons at operational level resulting from carrying out this project. Given the contextual details of the study, the lessons learned can help other firms to better anticipate the hurdles they will experience, and make them aware of the possible ways to cope with such difficulties before embarking on the journey of RFID implementation.     

Activism as a pathway to global citizenship

We examined the influence of prior work with activist issues on the antecedents, identification, and outcomes of global citizenship. Participants rated their engagement with activist issues and measures related to global citizenship identification antecedents and outcomes. The results showed that engagement with activist issues predicted global citizenship through the perceptions of one’s normative environment and global awareness. Activism also indirectly predicted prosocial values and behaviors related to global citizen identity through antecedents and global citizenship identification. The results highlight the prosocial outcomes of participation in activist movements.

虚拟社区与成员心理联结机制的实证研究:基于认同与纽带视角

对于虚拟社区成员与社区之间连接的关系纽带的本质与类型及其对网民参与行为的影响目前仍缺乏研究。本文基于社会认同理论和纽带理论的扩展与深化,揭示了网民参与虚拟社区的两种心理来源和心理依附机制。通过1028份问卷的实证调查,证明网民对虚拟身份的自我认同是社区认同的部分中介变量,社区成员通过纽带人际依恋和身份群组依恋共同构成与社区之间的心理联结系统,并且线下联系只有在社区内产生人际依恋时才会产生。文章也证明了社区类型对模型的调节作用,最后对该模型的理论贡献和管理应用意义进行了讨论。

异构小蜂窝网络移动性管理研究综述

新一代移动通信网络不断演进为高密集、无定型、立体分层的异构网络,移动性管理旨在保证用户设备（user equipment,UE）移动通信服务的连续性和无缝切换及降低信令开销等。移动性管理问题正成为异构小蜂窝网络（heterogeneous and small cell networks,HetNets）中无线资源管理需要应对的关键性挑战之一。阐述了移动性管理的一般性问题,根据移动性管理的主要特征给出了一个综合分类：整体切换性能增强、小蜂窝发现与识别增强和无线链路失效（radio link failure,RLF）恢复增强。此外,依据此分类对近年来第三代合作伙伴计划（3rd genera-tion partnership project,3GPP）成员在无线接入网（radio access network,RAN）标准化工作组历次会议中提出的主要移动性管理增强方案进行了分类阐述和性能对比。对异构小蜂窝网络的移动性管理所面临的挑战和未来研究的趋势进行展望,并在此基础上进行了总结。     

青年消费者全球化品牌认同的驱动因素与效应机理

基于社会认同理论探索青年消费者全球化品牌认同的驱动因素,考察驱动因素与品牌认同对全球化品牌购买倾向的影响,研究结果显示:全球化品牌认同的驱动因素包括全球维度、传播维度、真实维度与差异维度,其中,全球维度、传播维度是外在驱动线索,真实维度与差异维度是内在驱动线索。传播维度对品牌认同的影响作用最强,其次分别是差异维度与真实维度,而全球维度对全球化品牌认同影响不显著。另外,全球化品牌认同对品牌购买倾向有显著的影响。
